3 Simplify SIGIO usage (Bug#12408).
4 The code that dealt with SIGIO was crufty and confusing, e.g., it
5 played tricks like "#undef SIGIO" but these tricks were not used
6 consistently. Simplify mostly by not #undeffing standard symbols,
7 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
8 or not as we please) rather than "defined SIGIO" (standard symbol
9 that we probably shouldn't #undef).
10 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
11 Modules that need it can include it.
12 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
13 * dispextern.h (ignore_sigio): New decl.
14 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
15 unconditionally, since it's now a no-op if !USABLE_SIGIO.
16 * emacs.c (shut_down_emacs):
17 * keyboard.c (kbd_buffer_store_event_hold):
18 Use ignore_sigio rather than invoking 'signal' directly.
19 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
21 (FIONREAD, SIGIO): Do not #undef.
22 (tty_read_avail_input): Use #error rather than a syntax error.
23 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
24 for I_PIPE, used by SETUP_SLAVE_PTY.
25 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
26 * sysdep.c (croak): Remove; no longer needed. This bit of
27 temporary code, with Fred N. Fish's comment that it's temporary,
28 has been in Emacs since at least 1992!
29 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
30 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
31 * syssignal.h (croak): Remove decl.
32 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
33 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
34 now that we're termios-only.
35 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
36 * term.c (dissociate_if_controlling_tty): Use #error rather than
39 Work around GCC and GNOME bugs when --enable-gcc-warnings.
40 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
41 to work around GNOME bug 683906.
42 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
43 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
44 This works around GCC bug 54561.
46 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
48 More fixes for 'volatile' and setjmp/longjmp.
49 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
50 * image.c (struct png_load_context) [HAVE_PNG]: New type.
51 (png_load_body) [HAVE_PNG]:
52 (jpeg_load_body) [HAVE_JPEG]:
53 New function, with most of the old parent function's body.
54 (png_load) [HAVE_PNG]:
55 (jpeg_load) [HAVE_JPEG]:
56 Invoke the new function, to avoid longjmp munging our locals.
57 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
58 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
59 longjmp is passed 2, as the C standard doesn't guarantee this.
60 Instead, store the failure code into mgr->failure_code.
62 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
64 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
65 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
66 (syms_of_keyboard): Remove support for unread-command-char.
68 2012-09-12 Eli Zaretskii <eliz@gnu.org>
70 * w32proc.c (sys_kill): If PID is our process ID and the signal is
71 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
72 violation. (Bug#12426)
74 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
76 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
78 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
80 * eval.c: Add `inhibit-debugger'.
81 (Qinhibit_debugger): New symbol.
82 (call_debugger): Bind it instead of Qdebug_on_error.
83 (maybe_call_debugger): Test Vinhibit_debugger.
84 (syms_of_eval): Define inhibit-debugger.
85 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
86 (syms_of_xdisp): Remove inhibit-debug-on-message.
88 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
90 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
91 If a nonvolatile local variable is written before a _longjmp to
92 the frame containing the variable, and is read after the _longjmp,
93 the value read is indeterminate. Some local variables of type
94 'struct handler' and 'struct catchtag' are used in this way, so
95 mark each of their slots as volatile if the slot can be set before
96 _longjmp and read afterwards.
97 * lisp.h (struct handler): var and chosen_clause are now volatile.
98 (struct catchtag): val, next, and pdlcount are now volatile.
100 * bidi.c (bidi_push_it, bidi_pop_it):
101 * fns.c (copy_hash_table):
102 * image.c (define_image_type):
103 * keyboard.c (kbd_buffer_store_event_hold):
104 * process.c (Fprocess_send_eof):
105 * xfaces.c (x_create_gc) [HAVE_NS]:
106 * xgselect.c (xg_select):
107 Prefer assignment to memcpy when either will do.
109 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
110 Use pointer-to-a-pointer to simplify and avoid a NILP check each
111 time an item is removed. No need to mark this function 'inline';
112 the compiler knows better than we do.
114 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
116 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
117 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
118 to change_frame_size (Bug#12388).
119 (windowDidResize:): Pass YES to updateFrameSize.
121 * nsterm.h: Add delay parameter to updateFrameSize.
123 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
125 Discard killed buffers from deleted window and frame objects.
126 This reduces an amount of references to killed buffers and
127 helps GC to reclaim them faster.
128 * alloc.c (discard_killed_buffers): New function.
129 (mark_object): Use it for deleted windows and frames.
130 (mark_object): If symbol's value is set up for a killed buffer
131 or deleted frame, restore it's global binding.
132 * data.c (swap_in_global_binding): Add GC notice.
133 (swap_in_symval_forwarding): Use convenient set_blv_where.
134 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
135 * window.h: ... to here.
137 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
139 Convenient macro to check whether the buffer is live.
140 * buffer.h (BUFFER_LIVE_P): New macro.
141 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
142 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
144 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
146 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
147 composition cases (Bug#12364).
149 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
150 overhang of succeeding glyphs overlapping box cursor.
152 * w32term.c (x_draw_glyph_string): Likewise.
154 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
156 Simplify, document, and port floating-point (Bug#12381).
157 The porting part of this patch fixes bugs on non-IEEE platforms
158 with frexp, ldexp, logb.
159 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
161 * floatfns.c: Simplify discussion of functions that Emacs doesn't
162 support, by removing commented-out code and briefly listing the
163 C89 functions excluded. The commented-out stuff was confusing
164 maintenance, e.g., we thought we needed cbrt but it was commented out.
165 (logb): Remove decl; no longer needed.
166 (isfinite): New macro, if not already supplied.
167 (isnan): Don't replace any existing macro.
168 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
169 are present on all C89 platforms.
170 (Ffrexp): Do not special-case zero, as frexp does the right thing
172 (Flogb): Do not use logb, as it doesn't have the desired meaning
173 on hosts that use non-base-2 floating point. Instead, stick with
174 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
175 frexp, to avoid getting an unspecified result.
177 * xdisp.c (Qinhibit_debug_on_message): Now static.
179 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
181 * nsterm.m (ns_update_begin): Set clip path to whole view by using
182 NSBezierPath (Bug#12131).
184 2012-09-10 Chong Yidong <cyd@gnu.org>
186 * fns.c (Fdelq, Fdelete): Doc fix.
188 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
190 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
191 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
193 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
195 * lisp.h (make_lisp_ptr): New macro to replace XSET.
196 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
199 2012-09-09 Eli Zaretskii <eliz@gnu.org>
201 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
202 left fringe if the window has a left margin. This avoids leaving
203 traces of the cursor because its leftmost pixel is not drawn over.
205 * dispnew.c (update_window_line): When the left margin area of a
206 screen line is updated, set the redraw_fringe_bitmaps_p flag of
207 that screen line. (Bug#12277)
209 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
211 Assume C89 or later for math functions (Bug#12381).
212 This simplifies the code, and makes it a bit smaller and faster,
213 and (most important) makes it easier to clean up signal handling
214 since we can stop worring about floating-point exceptions in
215 library code. That was a problem before C89, but the problem
216 went away many years ago on all practical Emacs targets.
217 * data.c, image.c, lread.c, print.c:
218 Don't include <math.h>; no longer needed.
219 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
220 might be autoconfigured, as that never happens.
222 * doprnt.c (DBL_MAX_10_EXP):
224 Remove. C89 or later always defines these.
225 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
226 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
227 (arith_error, domain_error, domain_error2):
228 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
229 no longer needed -- we simply return what C returns. All uses removed.
230 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
232 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
233 Remove. All uses expanded, as these macros are no longer used
234 more than once and are now more trouble than they're worth.
235 (Ftan): Use tan, not sin / cos.
236 (Flogb): Assume C89 frexp.
237 (fmod_float): Assume C89 fmod.
238 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
239 (init_floatfns): Remove. All uses removed.
241 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
243 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
244 compositeToPoint for OSX < 10.6 (Bug#12390).
246 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
248 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
249 This produces more-accurate results.
251 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
253 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
256 2012-09-08 Chong Yidong <cyd@gnu.org>
258 * syntax.c (Fstring_to_syntax): Doc fix.
260 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
262 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
263 in the internal border.
264 (x_set_window_size): Remove static variables and their usage.
265 (ns_redraw_scroll_bars): Fix NSTRACE arg.
266 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
267 fringe/internal border adjustment (Bug#11052).
268 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
269 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
270 (ns_fix_rect_ibw): Remove.
271 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
272 (ns_dumpglyphs_box_or_relief): Ditto.
273 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
275 (ns_dumpglyphs_image): Ditto.
276 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
278 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
279 their usage. Add fringe_extended_p and its use as in other terms.
280 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
281 scroll bar was removed.
282 (updateFrameSize): New function.
283 (windowDidResize): Move code to updateFrameSize and call it.
285 * nsterm.h (EmacsView): Add updateFrameSize.
287 2012-09-07 Chong Yidong <cyd@gnu.org>
289 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
291 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
293 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
295 More signal-handler cleanup (Bug#12327).
296 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
297 Problem introduced when merging patches. Noted by Eli Zaretskii in
298 <http://bugs.gnu.org/12327#67>.
299 * floatfns.c: Comment fix.
300 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
301 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
302 and anyway the declaration is harmless even if SIGDANGER is not defined.
303 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
304 defined BROKEN_FIONREAD). systty.h formerly did this, but other
305 source files not surprisingly expected syssignal.h to define, or
306 not define, SIGIO, and it's cleaner to do it that way, for consistency.
307 Include <sys/ioctl.h>, for FIONREAD.
308 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
309 This eliminates a problem whereby other files mysteriously had
310 to include "syssignal.h" before including "systty.h" if they
311 wanted to use "#ifdef SIGIO".
313 2012-09-07 Eli Zaretskii <eliz@gnu.org>
315 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
317 * w32.c (sigemptyset): Empty the set.
318 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
320 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
322 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
324 * alloc.c (mark_buffer): Revert unsafe marking optimization.
325 (mark_object): Likewise for frame objects.
327 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
329 * syssignal.h (handle_on_main_thread): Always declare,
330 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
331 This ports to platforms without HAVE_PTHREAD.
333 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
335 Signal-handler cleanup (Bug#12327).
336 Emacs's signal handlers were written in the old 4.2BSD style with
337 sigblock and sigmask and so forth, and this led to some
338 inefficiencies and confusion. Rewrite these to use
339 pthread_sigmask etc. without copying signal sets around. Also,
340 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
341 'signal', and instead use functions that do not attempt to take
342 over the system name space. This patch causes Emacs's text
343 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
344 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
345 Do not include <signal.h> or "syssignal.h", as these
346 modules do not use signals.
347 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
348 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
349 Do not include <signal.h>, as "syssignal.h" does that for us now.
350 * atimer.c (sigmask_atimers): New function.
351 (block_atimers, unblock_atimers): New functions,
352 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
354 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
355 no longer needed here.
356 * emacs.c (main): Inspect existing signal handler with sigaction,
357 so that there's no need to block and unblock SIGHUP.
358 * sysdep.c (struct save_signal): New member 'action', replacing
359 old member 'handler'.
360 (save_signal_handlers, restore_signal_handlers):
361 Use sigaction instead of 'signal' to save and restore.
362 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
363 New function. All users of 'signal' modified to use set_sighandler
364 if they're writeonly, and to use sys_signal if they're read+write.
365 (emacs_sigaction_init, forwarded_signal): New functions.
366 (sys_signal): Remove. All uses replaced by calls to sigaction
367 and emacs_sigaction_init, or by direct calls to 'signal'.
368 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
369 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
370 all uses replaced by pthread_sigmask etc. calls.
371 * syssignal.h: Include <signal.h>.
372 (emacs_sigaction_init, forwarded_signal): New decls.
373 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
374 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
375 (sigmask, sys_sigmask): Remove; no longer needed.
376 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
377 (sigblock, sigunblock, sigfree):
378 (sigsetmask) [!defined sigsetmask]:
379 Remove. All uses replaced by pthread_sigmask.
380 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
381 no longer need to be replaced, and its typical old uses
382 are now done via emacs_sigaction_init and sigaction.
383 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
384 (sys_sigdel): Remove; unused.
385 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
387 2012-09-06 Eli Zaretskii <eliz@gnu.org>
389 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
390 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
392 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
394 Explicitly mark buffer_defaults and buffer_local_symbols.
395 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
396 mark_local_symbols here.
397 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
398 since special buffers aren't marked here any more.
399 (allocate_buffer): Chain new buffer with all_buffers here...
400 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
402 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
403 (syms_of_buffer): Remove staticpro of the above.
404 (init_buffer_once): Set names for buffer_defaults and
405 buffer_local_symbols.
407 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
409 Use bool for booleans in font-related modules.
410 * font.c (font_intern_prop, font_style_to_value)
411 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
412 (generate_otf_features, font_check_otf_features, font_check_otf)
413 (font_match_p, font_list_entities, font_at):
414 * fontset.c (fontset_id_valid_p, reorder_font_vector
415 (fontset_find_font, Fset_fontset_font)
416 (face_suitable_for_char_p) [0]:
417 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
418 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
419 (m17n_flt_initialized, ftfont_shape_by_flt):
420 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
421 * nsfont.m (nsfont_draw):
422 * w32font.c (w32font_draw):
423 * w32term.c (x_draw_glyphless_glyph_string_foreground):
424 Use bool for booleans.
425 * font.h: Adjust to above API changes.
426 (struct font, struct font_driver, struct font_driver_list):
427 Use bool for booleans.
428 (struct font): Remove useless member encoding_type.
430 * fontset.c, xftfont.c: Omit unnecessary static decls.
432 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
434 * alloc.c (mark_object): Revert window marking code
435 since it's unsafe for the Fset_window_configuration.
437 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
439 Fix race conditions with signal handlers and errno (Bug#12327).
440 Be more systematic about preserving errno whenever a signal
441 handler returns, even if it's not in the main thread. Do this by
442 renaming signal handlers to distinguish between signal delivery
443 and signal handling. All uses changed.
444 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
445 * data.c (deliver_arith_signal): Rename from arith_error.
446 * dispnew.c (deliver_window_change_signal): Rename from
447 window_change_signal.
448 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
449 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
450 * keyboard.c (deliver_input_available_signal): Rename from
451 input_available_signal.
452 (deliver_user_signal): Rename from handle_user_signal.
453 (deliver_interrupt_signal): Rename from interrupt_signal.
454 * process.c (deliver_pipe_signal): Rename from send_process_trap.
455 (deliver_child_signal): Rename from sigchld_handler.
456 * atimer.c (handle_alarm_signal):
457 * data.c (handle_arith_signal):
458 * dispnew.c (handle_window_change_signal):
459 * emacs.c (handle_fatal_signal, handle_danger_signal):
460 * keyboard.c (handle_input_available_signal):
461 * keyboard.c (handle_user_signal, handle_interrupt_signal):
462 * process.c (handle_pipe_signal, handle_child_signal):
463 New functions, with the actual signal-handling code taken from the
464 original respective signal handlers, sans the sporadic attempts to
465 preserve errno, since that's now done by handle_on_main_thread.
466 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
467 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
468 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
470 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
471 Move initialization of main_thread to sysdep.c's init_signals.
472 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
473 our usage, and simplifies the mainline code.
474 (record_child_status_change): New static function, as a helper
475 for handle_child_signal, and with most of the old child handler's
477 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
478 (handle_child_signal): Use the above.
479 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
480 Moved here from emacs.c.

482 code moved here from emacs.c's main function.
483 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
484 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
485 lets callers save and restore errno properly.
487 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
489 Remove redundant or unused things here and there.
490 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
491 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
492 * editfns.c (Fcompare_buffer_substrings): Likewise.
493 * frame.h (struct terminal, struct font_driver_list):
494 Remove redundant declarations.
495 * window.h (Qleft, Qright): Likewise.
497 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
499 Do not mark objects from deleted buffers, windows and frames.
500 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
501 (mark_object): Likewise for windows and frames.
503 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
505 * alloc.c (valid_lisp_object_p): Treat killed buffers,
506 buffer_defaults and buffer_local_symbols as valid objects.
507 Return special value to denote them.
509 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
511 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
512 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
513 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
514 (file_name_absolute_p, Fsubstitute_in_file_name):
515 (check_executable, check_writable, Ffile_accessible_directory_p)
516 (Fset_file_selinux_context, Fdefault_file_modes)
517 (Finsert_file_contents, choose_write_coding_system)
518 (Fwrite_region, build_annotations, a_write, e_write)
520 * filelock.c (boot_time_initialized, get_boot_time)
521 (get_boot_time_1, lock_file_1, within_one_second):
522 * floatfns.c (in_float):
523 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
524 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
525 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
526 * lisp.h (struct Lisp_Hash_Table.cmpfn):
527 * window.c (compare_window_configurations):
528 Use bool for booleans.
529 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
530 (Fdefault_file_modes): Now mode_t, not int, for modes.
531 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
532 (internal_delete_file): Now returns void, not a (boolean) int,
533 since nobody was looking at the return value.
534 * lisp.h, window.h: Adjust to above API changes.
536 * xdisp.c (set_message): Simplify and reindent last change.
538 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
540 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
542 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
544 * eval.c (call_debugger): Make the function non-static so that we
545 can call it from set_message.
547 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
548 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
550 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
552 Give more-useful info on a fatal error (Bug#12328).
553 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
554 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
555 of doing the work ourselves.
556 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
558 (fatal_error_backtrace): New function, taken from the guts
559 of the old fatal_error_signal, but with a new option to output
561 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
562 info about the signal than just its number.
563 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
564 * sysdep.c: Include <execinfo.h>
565 (emacs_backtrace): New function, taken partly from the previous
566 code of the 'die' function.
567 (emacs_abort): Call fatal_error_backtrace rather than abort.
569 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
571 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
572 eager (load-time) macro-expansion.
573 * lisp.mk (lisp): Add macroexp.
575 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
577 Simplify redefinition of 'abort' (Bug#12316).
578 Do not try to redefine the 'abort' function. Instead, redo
579 the code so that it calls 'emacs_abort' rather than 'abort'.
580 This removes the need for the NO_ABORT configure-time macro
581 and makes it easier to change the abort code to do a backtrace.
582 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
583 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
584 Remove; sysdep.c's emacs_abort now takes its place.
585 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
586 'abort' changed to use 'emacs_abort'.
587 * msdos.c (dos_abort) [defined abort]: Remove; not used.
588 (abort) [!defined abort]: Rename to ...
589 (emacs_abort): ... new name.
590 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
591 the place of the old 'abort' in emacs.c.
592 * w32.c, w32fns.c (abort): Do not #undef.
593 * w32.c (emacs_abort): Rename from w32_abort.
595 2012-09-04 Eli Zaretskii <eliz@gnu.org>
597 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
598 offsets[j].dv, since the y axis of the screen coordinates points
599 down, while the y axis of the font definition coordinates points
600 up. This fixes display of Arabic diacritics such as KASRA and
601 KASRATAN. (Bug#11860)
603 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
605 Be more systematic about _setjmp vs setjmp.
606 * alloc.c (test_setjmp, mark_stack):
607 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
608 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
609 (png_load, my_error_exit, jpeg_load):
610 * process.c (send_process_trap, send_process):
611 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
612 The underscored versions are up to 30x faster on some hosts.
613 Formerly, the code used setjmp+longjmp sometimes and
614 _setjmp+_longjmp at other times, with no particular reason to
615 prefer setjmp+longjmp.
617 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
619 Fix minor problem found by static checking.
620 * buffer.c (Fdelete_all_overlays): Return nil.
622 2012-09-03 Martin Rudalics <rudalics@gmx.at>
624 * buffer.c (Fdelete_all_overlays): New function.
626 2012-09-03 Chong Yidong <cyd@gnu.org>
628 * gtkutil.c: Add extern decl for Qxft.
630 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

635 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
636 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
637 (main, decode_env_path, Fdaemon_initialized):
638 * eval.c (call_debugger, Finteractive_p, interactive_p):

642 Use bool for booleans.
643 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.

646 EXCLUDE_SUBRS_P. All callers changed.
647 * dispextern.h, lisp.h: Reflect above API changes.
648 * firstfile.c (dummy): Use the address of 'main', whose signature
649 won't change, instead of the address of 'initialize', whose
650 signature just changed from int to bool.
651 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
652 * msdos.c (fatal_error_in_progress): ... from here.
653 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
655 (redisplay_internal, unwind_redisplay): Simply clear
656 REDISPLAYING_P when unwinding, instead of saving its previous,
657 always-false value and then restoring it.
659 Clean up some extern decls.
660 Mostly, this hoists extern decls out of .c files and into .h files.
661 That way, we're more likely to catch errors if the interfaces change.
662 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
663 declare xg_mark_data.
664 * dispextern.h (x_frame_parm_handlers):
666 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
667 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
668 (Qultra_bold, Qoblique, Qitalic):

681 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
682 * xfont.c (x_clear_errors):
683 * xterm.c (x_frame_parm_handlers):
684 Remove now-redundant extern decls.
685 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
686 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
688 * xfaces.c: Remove unnecessary static decls.
689 * xterm.c (updating_frame): Remove decl of nonexistent object.
691 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
692 when building globals.h, as the objects that are not built on
693 this host are not needed to compile C files on this host.
695 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
697 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

710 (format_time_string, general_insert_function)
711 (make_buffer_string, make_buffer_string_both)
712 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

730 2012-09-02 Chong Yidong <cyd@gnu.org>
732 * keymap.c (push_key_description): Print M-TAB as C-M-i
735 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
737 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
738 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

745 2012-09-01 Eli Zaretskii <eliz@gnu.org>
747 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
748 more than one grapheme cluster passed to the shaper: compute the
749 offset adjustment values separately for each cluster. (Bug#11860)
751 * image.c: Restore mistakenly removed inclusion of w32.h. Without
752 it, GCC doesn't see prototypes of w32_delayed_load, and complains
753 about implicit conversions from integer to pointer.
755 2012-09-01 Daniel Colascione <dancol@dancol.org>
757 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
758 system used too early.
760 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
762 Better seed support for (random).

764 * fns.c (Frandom): Set the seed from a string argument, if given.
765 Remove long-obsolete Gentzel cruft.
766 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.

791 * process.c: Include TERM_HEADER instead of listing all possible
792 window-system headers.

795 FRAME_X_SCREEN, FRAME_X_VISUAL.
797 * menu.c: Include TERM_HEADER instead of listing all possible
798 window-system headers.
800 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
803 * keyboard.c: Include TERM_HEADER instead of listing all possible
804 window-system headers.
806 * image.c: Include TERM_HEADER instead of listing all possible
807 window-system headers. Declare Vlibrary_cache when compiling for
810 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
811 window system declarations.
813 * frame.h: Move common functions here: set_frame_menubar,
814 x_set_window_size, x_sync, x_get_focus_frame,
815 x_set_mouse_position, x_set_mouse_pixel_position,
816 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
817 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
818 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,
819 x_activate_menubar, x_real_positions, x_bitmap_icon,
820 x_set_menu_bar_lines, free_frame_menubar, x_free_frame_resources,
823 * frame.c: Include TERM_HEADER instead of listing all possible
824 window-system headers.
826 * font.c: Include TERM_HEADER instead of listing all possible
827 window-system headers.

842 Remove mark_ttys function and fix tty_display_info initialization.
843 * lisp.h (mark_ttys): Remove prototype.
844 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
845 to mark_ttys because all possible values of 'top_frame' slot are
846 the frames which are reachable from Vframe_list.
847 * term.c (mark_ttys): Remove.
848 (init_tty): Safely initialize 'top_frame' slot with Qnil.
850 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
852 Change struct frame bitfields from unsigned char to unsigned.
853 * frame.h (struct frame): Change type of 'display_preempted',
854 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
855 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
856 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
857 bitfields from unsigned char to unsigned.

865 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
867 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
868 does not become zero (Bug#12234).
870 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
872 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
873 for GCC 4.7.1 x86-64.
875 2012-08-30 Glenn Morris <rgm@gnu.org>
877 * lread.c (init_lread): For out-of-tree builds, only add the
878 source directory's site-lisp dir to the load-path if it exists,
879 consistent with in-tree builds. (Bug#12302)
881 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
883 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
884 button_values to NULL. Call setStykeMask so dialogs get a close button.
885 (windowShouldClose:): Set window_closed.
886 (dealloc): New member, free button_values.
887 (process_dialog:): Make member function. Remove window argument,
888 replace window with self. Count buttons and allocate and store values
890 (addButton:value:row:): value is int with the name tag. Call setTag
891 with tag. Remove return self, declare return value as void.
892 (addString:row:): Remove return self, declare return value as void.
893 (addSplit): Remove return self, declare return value as void.
894 (clicked:): Remove return self, declare return value as void.
895 Set dialog_return to button_values[seltag]. Code formatting change.
896 (initFromContents:isQuestion:): Adjust call to process_dialog.
897 Code formatting change.
898 (timeout_handler:): Set timer_fired to YES.
899 (runDialogAt:): Set timer_fired to NO.
900 Handle click on close button as quit.
902 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
903 Add window_closed and button_values. Add void as return value for
904 add(Button|String|Split). addButton takes int instead of Lisp_Object.
905 Add process_dialog as new member.
907 2012-08-28 Eli Zaretskii <eliz@gnu.org>
909 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
910 is not one of the heaps we manage. (Bug#12242)
912 2012-08-28 Glenn Morris <rgm@gnu.org>
914 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

952 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
954 * dispnew.c: Use bool for boolean.
955 (frame_garbaged, display_completed, delayed_size_change)

968 (update_frame_1, scrolling, buffer_posn_from_coords)
969 (do_pending_window_change, change_frame_size)
970 (change_frame_size_1, sit_for):
971 Use bool for boolean.
972 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
973 and remove last int (actually boolean) argument, which was always 0.
975 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
976 * dispextern.h (struct composition_it): Use bool for boolean.
977 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
978 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
979 * dired.c (file_name_completion):
980 Use bool for boolean. (This was missed in an earlier change.)
982 2012-08-27 Martin Rudalics <rudalics@gmx.at>
984 * window.c (Fset_window_configuration): Revert first part of
987 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
989 * nsterm.h (NSPanel): New class variable dialog_return.
991 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
993 (windowShouldClose:): Use stop instead of stopModalWithCode.
994 (clicked:): Ditto, and also set dialog_return (Bug#12258).
995 (timeout_handler:): Use stop instead of abortModal. Send a dummy
997 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
1000 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
1002 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
1003 * composite.c (find_composition, composition_gstring_p)
1004 (composition_reseat_it, find_automatic_composition):

1012 Use bool for booleans.
1013 * dired.c (file_name_completion):
1014 * process.h (fd_callback):
1015 Omit int (actually boolean) argument. It wasn't being used.
1017 * composite.h, lisp.h: Reflect above API changes.

1040 (Fset_coding_system_priority):
1041 * fileio.c (Finsert_file_contents):
1042 Use bool for booleans.
1043 * coding.h, lisp.h: Reflect above API changes.
1044 * coding.c: Remove unnecessary static function decls.
1045 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
1046 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
1047 not a boolean 'int', since callers never look at the return value.
1048 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
1049 * coding.h (decoding_buffer_size, encoding_buffer_size)
1050 (emacs_mule_string_char): Remove unused extern decls.
1051 (struct iso_2022_spec, struct coding_system):
1052 Use 'unsigned int : 1' for boolean fields, since there's more than one.
1053 (struct emacs_mule_spec): Remove unused field 'full_support'.
1054 All initializations removed.
1055 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
1057 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1059 Fix spare memory change (Bug#12286).
1060 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
1061 (valid_lisp_object_p): Likewise.
1063 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1065 * window.c (Fset_window_configuration): Record any window's old
1066 buffer if it's replaced (see Bug#8789). If the new current
1067 buffer doesn't appear in the selected window, go to its old
1070 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1072 Special MEM_TYPE_SPARE to denote reserved memory.
1073 * alloc.c (enum mem_type): New memory type.
1074 (refill_memory_reserve): Use new type for spare memory.
1075 This prevents live_cons_p and live_string_p from incorrect
1076 detection of uninitialized objects from spare memory as live.
1078 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1081 * Makefile.in (.PHONY): versioclean -> versionclean.
1083 Remove unused external symbols.
1084 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1085 * window.c (Qwindow_valid_p, decode_valid_window):
1086 Now static, not extern.
1087 * data.c (Qinterval): Remove; unused.
1088 (syms_of_data): Do not define 'interval'.
1089 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1090 * window.h (decode_valid_window):
1093 * character.c, charset.c, chartab.c: Use bool for booleans.
1094 * character.c (lisp_string_width, string_count_byte8)
1095 (string_escape_byte8):
1096 * charset.c (charset_map_loaded, load_charset_map, read_hex):
1097 (load_charset_map_from_file, map_charset_chars)

1099 (Fdeclare_equiv_charset, find_charsets_in_text)
1100 (Ffind_charset_region, char_charset, Fiso_charset):
1101 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1102 (sub_char_table_set, sub_char_table_set_range)
1103 (char_table_set_range, optimize_sub_char_table)
1104 (map_sub_char_table):
1105 Use bool for boolean.
1106 * character.c (str_to_unibyte): Omit last boolean argument; it was
1107 always 0. All callers changed.
1108 * character.h, charset.h: Adjust to match previous changes.
1109 * character.h (char_printable_p): Remove decl of nonexistent function.
1110 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1111 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1112 are all boolean, so make them single-bit bitfields.
1114 * lisp.h (ASET): Remove attempt to detect side effects.
1115 It was meant to be temporary and it often doesn't work,
1116 because when IDX has side effects the behavior of IDX==IDX
1117 is undefined. See Stefan Monnier in
1118 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1120 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1122 * lisp.h (functionp): New function (extracted from Ffunctionp).
1123 (FUNCTIONP): Use it.
1124 * eval.c (Ffunctionp): Use it.
1126 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1128 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1129 as that's faster and simpler than static storage. Don't bother
1130 with the g_main_context_query overhead if g_main_context_pending
1131 says no events are pending.
1132 (gfds, gfds_size): Remove these static vars.
1133 (xgselect_initialize): Remove; no longer needed.
1134 All uses and decls removed.
1136 * emacs.c (fatal_error_signal_hook): Remove.
1137 All uses removed. This leftover from old code was always 0.
1139 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1140 * casefiddle.c (casify_object, casify_region):
1141 * casetab.c (set_case_table):
1142 * category.c, category.h (word_boundary_p):
1143 * category.h (CHAR_HAS_CATEGORY):
1144 Use bool for booleans, instead of int.
1146 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1148 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1150 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1152 On assertion failure, print backtrace if available.
1153 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1154 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1155 * Makefile.in (LIB_EXECINFO): New macro.
1158 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1159 * bytecode.c (exec_byte_code):
1160 * callint.c (check_mark, Fcall_interactively):
1161 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1162 (getenv_internal, sync_process_alive, call_process_exited):
1163 * lisp.h (USE_SAFE_ALLOCA):
1164 Use bool for booleans, instead of int.
1165 * lisp.h, process.h: Adjust prototypes to match above changes.
1166 * callint.c (Fcall_interactively): Don't assume the mark's
1167 offset fits in 'int'.
1169 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1171 * buffer.c, buffer.h: Use bool for boolean.
1172 * buffer.c (reset_buffer_local_variables)
1173 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1174 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

1176 (overlay_touches_p, overlay_strings, Foverlay_put)
1177 (report_overlay_modification, call_overlay_mod_hooks):
1178 (mmap_enlarge, mmap_set_vars):
1179 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1180 Use bool for booleans, instead of int.
1181 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1182 since the 1-or-0 return value is always ignored anyway.
1183 (mmap_initialized_p):
1184 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1185 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1187 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1189 * bidi.c: Use bool for boolean.
1190 This is a bit more readable, and makes the text segment of bidi.o
1191 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1192 Presumably it's faster too.
1193 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1195 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1196 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1197 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1198 (bidi_explicit_dir_char, bidi_level_of_next_char)
1199 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1200 Use bool for booleans, instead of int.
1201 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1202 (bidi_unshelve_cache): Adjust decls to match code.
1204 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1206 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1209 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1211 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1212 * atimer.h: Include <stdbool.h>.
1214 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1216 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1217 compile time tests instead of run time tests on systems that do
1219 (FRAME_MAC_P): Remove leftover from deleted code.
1220 * frame.c (syms_of_frame): Remove leftover from deleted code.
1222 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1224 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1226 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1228 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1229 Otherwise, the compiler complains about (A?B:C) where B is void
1230 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1231 (fontset_add): Return void, for FONTSET_ADD.
1233 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1235 * alloc.c: Use bool for booleans.
1236 (gc_in_progress, abort_on_gc)
1237 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1238 (dont_register_blocks) [GC_MALLOC_CHECK]:
1239 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1240 (check_string_bytes, make_specified_string, memory_full)
1241 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1242 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1243 (mark_stack, valid_pointer_p, make_pure_string)
1244 (Fgarbage_collect, survives_gc_p, gc_sweep):
1245 Use bool for booleans, instead of int.
1246 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1247 Remove unused local.
1248 * alloc.c (PURE_POINTER_P):
1249 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1250 * editfns.c (Fformat):
1251 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1253 * fns.c (sweep_weak_table):
1254 * lisp.h (suppress_checking, push_message, survives_gc_p)
1255 (make_pure_string, gc_in_progress, abort_on_gc):
1256 * lread.c (readchar, read1):
1257 * print.c (Fprin1_to_string):
1258 * xdisp.c (push_message):
1259 Use bool for booleans affected directly or indirectly by
1262 Make recently-introduced setters macros.
1263 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1264 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1265 (set_fontset_default, set_fontset_fallback): Rename from their
1266 upper-case counterparts, and make them functions rather than macros.
1267 This is more consistent with the other recently-introduced setters.
1268 These don't need to be inline, since they're local.
1270 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1272 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1273 the loop (Bug#12247).
1275 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1277 * lisp.h (vcopy): Use memcpy rather than our own loop.
1278 This fixes a performance regression introduced by the recent
1279 addition of vcopy. This means 'vcopy' will need to be modified
1280 for a copying collector, but that's OK. Also, tighten the
1281 checking in the assertion.
1283 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1285 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1286 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1287 non-base glyph for the width of the base character, according to
1288 what x_draw_composite_glyph_string_foreground expects.
1289 Generate WADJUST value according to composition_gstring_width's
1290 expectations, to produce correct width of the composed character.
1291 Reverse the sign of the DU offset produced by ScriptPlace.
1293 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1295 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1297 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1299 Avoid direct writes to contents member of struct Lisp_Vector.
1300 * lisp.h (vcopy): New function to copy data into vector.
1301 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1302 * fns.c (Ffillarray): Use ASET.
1303 * keyboard.c (timer_check_2): Use AREF and ASET.
1304 (append_tool_bar_item, Frecent_keys): Use vcopy.
1305 * lread.c (read_vector): Use ASET.
1306 * msdos.c (Frecent_doskeys): Use vcopy.
1307 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1308 (Finternal_merge_in_global_face): Use ASET and vcopy.
1309 * xfont.c (xfont_list_pattern): Likewise.
1311 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1313 * window.c (Fwindow_point): For the selected window always return
1314 the position of its buffer's point.
1315 (Fset_window_point): For the selected window always go in its
1316 buffer to the specified position.
1318 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1320 Setter macros for fontsets.
1321 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1322 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1323 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1326 2012-08-20 Glenn Morris <rgm@gnu.org>
1328 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1329 Don't assume that `ln -f' works.
1331 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1333 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1334 and later about non-assignments with no effect. See discussion at
1335 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1338 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1340 Inline setter functions for Lisp_Objects slots of struct specbinding.
1341 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1344 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1346 * window.c (select_window): Always make selected window's buffer
1349 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1351 Use AREF and ASET for docstrings of category tables.
1352 * category.h (CATEGORY_DOCSTRING): Use AREF.
1353 (SET_CATEGORY_DOCSTRING): Use ASET.
1354 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1356 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1358 Inline setter functions for hash table members.
1359 * lisp.h (set_hash_key, set_hash_value, set_hash_next)

1377 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1379 Rely on <config.h> + <unistd.h> to declare 'environ',
1380 as gnulib does this if the system doesn't.
1381 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

2250 2012-08-04 Eli Zaretskii <eliz@gnu.org>
2252 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
2253 * w32.c (init_environment): Change the default values of many
2254 environment variables in dflt_envvars[] to NULL, to avoid pushing
2255 them into environment when they were not already defined.
2256 Remove the code that deletes site-lisp subdirectories from the default
2257 value of EMACSLOADPATH, as it is no longer needed.
2258 (check_windows_init_file): Now external, not static.
2259 Use Vload_path as is, without adding anything, as this function is now
2260 called when Vload_path is already set up.
2262 * w32.h (check_windows_init_file): Add prototype.
2264 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
2265 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
2266 compatibility with Posix platforms.
2267 (main): Move the call to check_windows_init_file to here from
2269 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
2270 any, in the DEFALT argument into the root of the Emacs build or
2271 installation tree, as appropriate.
2273 * callproc.c (init_callproc_1): Call decode_env_path instead of
2274 doing its equivalent by hand.
2275 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
2276 the code that sets Vexec_path run on MS-Windows.
2278 * lread.c (init_lread): Add comments to #ifdef's.
2280 * msdos.c (dos_set_window_size, IT_update_begin)
2281 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
2282 instead of direct references.
2284 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
2286 Export DEFAULT_REHASH_* to GDB.
2287 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
2288 Now constants, not macros.
2290 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
2292 Remove unnecessary casts involving pointers.
2293 These casts are no longer needed now that we assume C89 or later,
2294 since they involve casting to or from void *.
2295 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
2296 (make_pure_float, make_pure_vector):
2297 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

2306 (x_get_window_property, x_get_window_property_as_lisp_data):
2307 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
2308 Remove unnecessary pointer casts.
2309 * alloc.c (record_xmalloc): New function.
2310 * lisp.h (record_xmalloc): New decl.
2311 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2312 more like a function. This is because the pointer cast is not
2313 needed. All uses changed.
2314 * print.c (print_string, print_error_message): Avoid length recalc.
2316 Improve fix for macroexp crash with debugging (Bug#12118).
2317 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2318 ARRAY_MARK_FLAG when checking subscripts, because ASET is
2319 not supposed to be invoked from the garbage collector.
2320 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
2321 (gc_aset): New function, which is like ASET but can be
2322 used in the garbage collector.
2323 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
2324 (set_hash_index): Use it instead of ASET.

2333 <g_b_init_create_symbolic_link>: New static flags.
2334 (globals_of_w32): Initialize them to zero.
2335 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
2336 (map_w32_filename): Improve commentary. Simplify switch.
2337 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
2338 headers (most versions of MinGW w32api don't).
2339 (get_security_info, create_symbolic_link)
2340 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
2342 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
2343 in the argument file name.
2344 (sys_access): Call unc_volume_file_attributes only if

2346 (sys_rename): Diagnose renaming of a symlink when the user doesn't
2347 have the required privileges.
2348 (get_file_security_desc_by_name): Rename from
2349 get_file_security_desc.
2350 (stat_worker): New function, with most of the guts of 'stat', and
2351 with addition of handling of symlinks and support for 'lstat'.
2352 If possible, get file's attributes and security information by
2353 handle, not by name. Produce S_IFLNK bit for symlinks, when
2354 called from 'lstat'.
2355 (stat, lstat): New functions, call 'stat_worker'.
2356 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2357 symlinks when the underlying filesystem supports them.
2359 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2361 Fix macroexp crash on Windows with debugging (Bug#12118).
2362 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2363 checking subscripts; problem introduced with the recent
2364 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2365 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2366 since it's used in non-static inline functions now.
2368 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2369 Don't assume buffer size fits in 'int'. Remove unused local.
2371 Use C99-style 'extern inline' if available.

2383 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2384 * alloc.c (LISP_INLINE):

2386 * category.c (CATEGORY_INLINE):
2387 * character.c (CHARACTER_INLINE):
2388 * charset.c (CHARSET_INLINE):
2389 * composite.c (COMPOSITE_INLINE):
2390 * dispnew.c (DISPEXTERN_INLINE):
2391 * sysdep.c (SYSTIME_INLINE):
2392 Define to EXTERN_INLINE, so that the corresponding functions
2393 are compiled into code.
2394 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
2395 (INLINE_HEADER_END): New macros.
2396 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

2416 hard-coding the path separator.
2418 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
2420 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
2421 This how ASET and AREF are supposed to work, and makes
2422 it easier to think about future improvements. See
2423 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
2424 * charset.h (set_charset_attr): New function.
2425 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
2426 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

2805 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
2806 (w32_kbd_patch_key, key_event): Use the codepage returned by
2807 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

2839 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
2840 enumeration constants, as PURE and HEAP are too general, and clash
2841 with other headers and sources, such as gmalloc.c and the
2842 MS-Windows system headers. All users changed.
2844 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2846 Revert last save_excursion_save and save_excursion_restore changes.
2847 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

2862 complains about the types in the unevaluated arm when the argument
2863 is an integer literal.
2864 (xgetint): Simplify expression.
2865 * alloc.c (gdb_make_enums_visible): New constant. This ports to
2866 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
2867 Zaretskii in <http://bugs.gnu.org/12036#13>.
2868 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
2869 needed now that we have gdb_make_enums_visible.
2870 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
2871 (enum enum_USE_LSB_TAG):
2872 New enum types, packaging up enums that need to be exported to GDB.

2914 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
2915 emacs.c, as this is a more-suitable home. Had this been done earlier
2916 the fix for 12036 would have avoided some of the problems noted in
2917 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
2918 would have been more obvious.
2919 * emacs.c: Do not include <verify.h>; no longer needed.
2920 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
2921 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
2922 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

2928 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
2929 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
2930 not be usable in #if. This simplifies things.
2932 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
2934 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

2939 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
2940 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
2941 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
2942 Adjust to changes in lisp.h and emacs.c, by using
2943 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
2944 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
2945 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
2946 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
2947 instead of gdb_valbits.
2948 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
2949 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
2950 instead of gdb_array_mark_flag.
2951 (xboolvector): Get size from $->size, not $->header.size.
2952 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
2953 (xreload, hook-run, hookpost-run): Remove.
2954 * emacs.c: Include <verify.h>.
2955 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
2956 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
2958 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
2959 (gdb_USE_LSB_TAG): New enum constants.
2960 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2961 Also define these as enum constants, so they're visible to GDB.
2962 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
2963 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
2964 as constants, so they're visible to GDB.

2967 Now enum constants, not macros, so they're visible to GDB.
2968 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
2969 more convenient now. All uses changed.
2970 (VALMASK) [USE_LSB_TAG]: Also define in this case.
2971 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
2973 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

2980 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
2981 add argument, tune behavior, and adjust all callers.
2983 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
2985 Use typedef for EMACS_INT, EMACS_UINT.
2986 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
2987 than macros. This simplifies debugging in the usual case, since
2988 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
2989 and it allows expressions involving EMACS_INT casts.
2990 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
2992 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

3004 Adjust buffer text indirection counters at the end of Fkill_buffer.
3005 * buffer.c (Fkill_buffer): Adjust indirection counters when the
3006 buffer is definitely dead. This should really fix an issue reported
3007 by Christoph Scholtes again. (Bug#12007).
3008 (init_buffer_once): Initialize indirection counters of
3009 buffer_defaults and buffer_local_symbols (for sanity and safety).
3011 2012-07-24 Eli Zaretskii <eliz@gnu.org>
3013 * xdisp.c (init_iterator): Don't compute dimensions of truncation
3014 and continuation glyphs on tooltip frames, leave them at zero.

3040 (build_overlay): Add prototype.
3042 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
3044 Swap buffer text indirection counters in Fbuffer_swap_text.
3045 * buffer.c (Fbuffer_swap_text): Swap indirections too.
3046 This avoids crash reported by Christoph Scholtes at
3047 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
3049 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
3051 * nsmenu.m (Popdown_data): New struct.
3052 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
3054 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
3055 (initWithContentRect): Make imgView and contentView non-static
3056 and autorelease them. Also autorelease img and matrix (Bug#12005).
3057 (dealloc): Remove (Bug#12005).
3059 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
3061 Adjust consing_since_gc when objects are explicitly freed.

3074 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
3076 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
3077 as it's limited by the amount of memory, not by INT_MAX.
3079 2012-07-21 Eli Zaretskii <eliz@gnu.org>
3081 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
3082 in special-event-map. See the discussion at

3805 * s/aix4-2.h (unix): Remove; no longer needed.
3807 EMACS_TIME simplification (Bug#11875).
3808 This replaces macros (which typically do not work in GDB)
3809 with functions, typedefs and enums, making the code easier to debug.
3810 The functional style also makes code easier to read and maintain.
3811 * systime.h: Include <sys/time.h> on all hosts, not just if
3812 WINDOWSNT, since 'struct timeval' is needed in general.

3825 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
3826 not functions. All uses rewritten to use the following, respectively:
3827 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
3828 (add_emacs_time, sub_emacs_time): New functions.
3829 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

3850 * nsterm.m: Include <ftoastr.h>.
3852 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
3853 Prefer snprintf to strncpy.
3854 * nsterm.m (ns_term_init):
3855 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
3856 * nsterm.m (ns_term_init):
3857 Avoid the need for strncpy, by using build_string or
3858 make_unibyte_string directly. Use dtoastr, not snprintf.
3859 * process.c (Fmake_network_process): Diagnose service names that
3860 are too long, rather than silently truncating them or creating
3861 non-null-terminated names.
3862 (Fnetwork_interface_info): Likewise, for interface names.
3863 * sysdep.c (system_process_attributes) [GNU_LINUX]:
3864 Prefer sprintf to strncat.

3871 Clarify fallback case.
3873 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

3877 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
3878 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
3879 where argument type is known to be a Lisp_Cons.

3934 O_RDONLY already includes it).
3936 Stop ns builds setting the EMACSLOADPATH environment variable.
3937 * nsterm.m (ns_load_path): Rename from ns_init_paths.
3938 Now it does not set EMACSLOADPATH, just returns the load-path string.

3940 * lread.c [HAVE_NS]: Include nsterm.h.
3941 (init_lread) [HAVE_NS]: Use ns_load_path.

3951 (ns_init_paths): Do not set EMACSPATH.

4009 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4011 Move marker debugging code under MARKER_DEBUG.
4012 * marker.c (MARKER_DEBUG): Move marker debugging code under
4013 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4014 for bootstrap with --enable-checking (~3x slowdown reported
4015 by Juanma Barranquero <lekktu@gmail.com>).
4016 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4018 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4020 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4021 See <http://bugs.gnu.org/11825#29>.
4023 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4025 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4026 has no font, use the frame's font. (Bug#11813)
4027 (display_line): Add commentary about displaying truncation glyphs
4029 (produce_special_glyphs): Move here from term.c.
4031 * term.c (produce_special_glyphs): Move to xdisp.c.
4033 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4036 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4038 * xdisp.c (display_line): Avoid warning about implicit declaration
4041 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4043 * lisp.h: Remove empty conditional.
4045 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4047 * lread.c (load_path_check): Now static.
4049 Fix some minor --with-ns problems found by static checking.
4050 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4051 (x_set_font) [!HAVE_X_WINDOWS]:
4052 * image.c (xpm_load_image) [HAVE_NS]:
4053 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4054 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4055 Remove unused local.
4056 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4057 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4058 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4059 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4060 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4061 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4062 Fix pointer signedness problem.
4063 * xfaces.c (FRAME_X_FONT_TABLE):
4064 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4066 2012-07-07 Glenn Morris <rgm@gnu.org>
4068 * lread.c (load_path_check): New function, split from init_lread.
4069 (init_lread): Reorganize. Motivation:
4070 If EMACSLOADPATH is set, check/warn about that rather than the
4071 defaults, which we are not going to use. Hence we can remove
4072 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4073 Don't warn if site-lisp directories are missing.
4074 If not installed, start from a blank load-path, since
4075 PATH_LOADSEARCH refers to the eventual installation directories.
4077 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4079 Support truncation and continuation glyphs on GUI frames, when
4080 fringes are disabled. (Bug#11832)
4081 * xdisp.c (init_iterator): Get dimensions of truncation and
4082 continuation glyphs even if on GUI frames.
4083 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4084 or both, are absent.
4085 (start_display, move_it_in_display_line_to): Handle the case of a
4086 GUI frame without a fringe to display continuation or truncation
4088 (insert_left_trunc_glyphs): Support GUI frames: make sure
4089 truncation glyphs overwrite enough glyphs from the current line to
4090 have sufficient space in pixels.
4091 (display_line): Support truncation and continuation glyphs on GUI
4092 frames. If some spare pixels are left on the line after inserting
4093 the truncation glyphs, fill that space with a stretch glyph of a
4094 suitably computed width.
4096 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4097 produce_glyphs, to support GUI sessions.
4099 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4101 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4103 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4105 Do not require float-time's arg to fit in time_t (Bug#11825).
4106 This works better on hosts where time_t is unsigned, and where
4107 float-time is applied to the (negative) difference between two times.
4108 * editfns.c (decode_time_components): Last arg is now double *,
4109 not int *, and means to store all the result as a double, without
4110 worrying about whether the seconds part fits in time_t.
4111 All callers changed.
4112 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4113 All callers changed.
4114 (Ffloat_time): Do not fail merely because the specified time falls
4115 outside of time_t range.
4117 2012-07-07 Glenn Morris <rgm@gnu.org>
4119 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4120 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
4121 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
4123 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4125 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4126 Update dependencies.
4128 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4130 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4132 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4133 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4134 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4135 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4136 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4137 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4139 * xfont.c (compare_font_names): Redo to omit the need for casts.
4141 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4143 * xfns.c (Fx_change_window_property): Doc fix.
4144 * w32fns.c (Fx_change_window_property): Doc fix.
4146 * w32fns.c (Fx_window_property): Accept the same arguments as the
4147 X Windows version. Doc fix.
4148 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4150 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4151 Eli Zaretskii <eliz@gnu.org>
4153 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4154 Windows-specific code from nt/config.nt moved here.
4155 Obsolete settings removed.
4157 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4159 * process.c: Avoid unnecessary calls to gettime.
4160 (wait_reading_process_output): Don't get the time of day
4161 when gobbling data immediately and not waiting, as there's no need
4162 for it in that case. This removes a FIXME.
4164 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4166 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4167 is defined (Bug#11768).
4169 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4171 Fix marker debugging code.
4172 * marker.c (byte_char_debug_check): Do not perform the check
4173 if buffer is not multibyte.
4174 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4175 Call byte_char_debug_check with correct arguments.
4177 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4179 Compile marker debugging code only if ENABLE_CHECKING is defined.
4180 * marker.c (byte_char_debug_check, count_markers):
4181 Use only if ENABLE_CHECKING is defined.
4182 (byte_debug_flag): Remove.
4183 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4184 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4186 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4188 Avoid code repetition in marker-related functions.
4189 * marker.c (attach_marker): New function.
4190 (Fset_marker, set_marker_restricted, set_marker_both)
4191 (set_marker_restricted_both): Use it.
4192 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4193 Consistently rename charno to charpos.
4194 (marker_position): Add eassert.
4195 (marker_byte_position): Convert to eassert.
4197 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4199 Simplify list operations in unchain_overlay and unchain_marker.
4200 * buffer.c (unchain_overlay): Simplify. Add comment.
4201 * marker.c (unchain_marker): Simplify. Fix comments.
4203 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4205 Introduce fast path for the widely used marker operation.
4206 * alloc.c (build_marker): New function.
4207 * lisp.h (build_marker): New prototype.
4208 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4209 * composite.c (autocmp_chars): Likewise.
4210 * editfns.c (buildmark): Remove.
4211 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4212 (save_restriction_save): Use build_marker.
4213 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4214 * window.c (save_window_save): Likewise.
4216 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4218 Do not use Fdelete_overlay in delete_all_overlays
4219 to avoid redundant calls to unchain_overlay.
4220 * buffer.c (drop_overlay): New function.
4221 (delete_all_overlays, Fdelete_overlay): Use it.
4222 * minibuf.c (get_minibuffer): Fix comment.
4224 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4226 Port to OpenBSD 5.1 amd64.
4227 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4228 This is needed for OpenBSD, and should be harmless on all BSD systems.
4229 Also, include <sys/sysctl.h>, as it should be available on all
4230 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4231 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4232 use p_pid member, not kp_proc.pid.
4234 2012-07-06 Glenn Morris <rgm@gnu.org>
4236 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4238 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4240 More xmalloc and related cleanup.
4241 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
4242 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
4243 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

4247 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
4248 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4249 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4251 Omit needless casts involving void * pointers and allocation.
4252 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4253 as the former is more robust if P's type is changed.
4254 Prefer xzalloc to xmalloc + memset 0.
4255 Simplify malloc-or-realloc to realloc.
4256 Don't worry about xmalloc returning a null pointer.
4257 Prefer xstrdup to xmalloc + strcpy.
4258 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4260 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4261 alloca of a constant.
4263 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4265 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4266 hscroll is larger than the line width. Fixes long and futile
4267 looping inside extend_face_to_end_of_line (on a TTY) producing
4268 glyphs that are not needed and thrown away.
4270 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4272 * marker.c (set_marker_restricted_both): Simplify by using
4275 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4277 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4279 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4281 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4282 not defined (Bug#11768).
4283 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4284 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4285 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4286 followed by gtk_box_set_homogeneous (Bug#11768).
4287 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4288 (update_theme_scrollbar_width, xg_create_scroll_bar):
4289 Use gtk_scrollbar_new (Bug#11768).
4290 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4291 (is_box_type): New function (Bug#11768).
4292 (xg_tool_item_stale_p): Call is_box_type.
4293 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4294 with default display (Bug#11768).
4296 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4298 * xdisp.c (window_hscroll_limited): New function.
4299 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4300 coordinates when window's hscroll is set to insanely large
4303 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4305 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4306 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4308 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4311 * lisp.h (xzalloc): New prototype. Omit needless casts.
4312 * alloc.c (xzalloc): New function. Omit needless casts.
4313 * charset.c: Omit needless casts. Convert all calls to
4314 xmalloc with following memset to xzalloc.
4315 * dispnew.c: Likewise.
4316 * fringe.c: Likewise.
4317 * image.c: Likewise.

4364 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4366 * fileio.c (time_error_value): Check the right error number.
4367 Problem reported by Troels Nielsen in
4368 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4370 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4372 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4373 This should be fixed in a better way; see Eli Zaretskii in
4374 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4375 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4377 * fileio.c (time_error_value): Rename from special_mtime.
4378 The old name's problems were noted by Eli Zaretskii in
4379 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4381 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4382 This variable's comment says Emacs needs at least one GDB-visible
4383 symbol of type enum pvec_type, to work around GDB problems.
4384 The symbol's value doesn't matter.
4386 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4387 that causes compilation to fail on pre-C99 compilers.
4389 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4391 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4392 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4394 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4396 * buffer.c (init_buffer_once): Fix initialization of
4397 headers for buffer_defaults and buffer_local_symbols.
4398 Reported by Juanma Barranquero <lekktu@gmail.com>.
4400 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4402 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4403 * lisp.h (enum pvec_type): Use fewer bits.
4404 (PSEUDOVECTOR_SIZE_BITS): New constant.
4405 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4406 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4407 change in pvec_type.
4408 (PSEUDOVECTOR_TYPEP): New macro.
4409 (TYPED_PSEUDOVECTORP): Use it.
4410 * fns.c (internal_equal): Adapt code to extract pvectype.
4411 * emacs.c (gdb_pvec_type): Update type.
4412 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4413 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4414 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4415 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4416 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4417 abusing vector->header.next.nbytes.
4418 (live_vector_p): Use PVEC_TYPE.
4419 (mark_object): Adapt code to extract pvectype. Use switch.
4421 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4423 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4424 Tighten new eassert a bit.
4426 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4428 Fix compilation with --enable-gcc-warnings and -O1
4430 * doprnt.c (doprnt): Change type of tem to int, initialize
4431 to avoid compiler warning. Add eassert.
4432 * search.c (simple_search): Initialize match_byte to avoid
4433 compiler warning. Add eassert.
4435 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4437 Avoid weird behavior with large horizontal scrolls.
4438 Without this change, for example, large hscroll values would
4439 mess up Emacs's display on Fedora 15 x86, presumably due to
4440 overflows in int calculations in the display code.
4441 Also, if buffers had long lines, Emacs would freeze.
4442 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4443 (set_window_hscroll): New function, containing the old guts of
4444 Fset_window_hscroll. Return the clipped value.
4445 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4446 This avoids the need to check against PTRDIFF_MAX.
4448 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4450 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4452 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4454 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4456 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4457 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4458 since GCC 4.4.6 issues a bogus warning for them.
4460 Fix bugs in file timestamp newness comparisons.
4461 * fileio.c (Ffile_newer_than_file_p):
4462 * lread.c (Fload): Use full timestamp resolution of files,
4463 not just the 1-second resolution, so that files that are only
4464 slightly newer still count as newer.
4465 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4466 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4468 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4470 * fileio.c: Improve handling of file time marker. (Bug#11852)
4471 (special_mtime): New function.
4472 (Finsert_file_contents, Fverify_visited_file_modtime):
4473 Use it to set special mtime values consistently.
4475 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4477 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4478 marker for non-existing file. (Bug#11852)
4480 2012-07-03 Glenn Morris <rgm@gnu.org>
4482 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4483 and did not make it into globals.h).
4485 2012-07-03 Tom Tromey <tromey@redhat.com>
4487 * window.c (Fset_window_margins, Fset_window_fringes)

4532 values which aren't power of 2.
4533 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4534 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4537 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4539 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

4545 * alloc.c (allocate_vector_block): Remove redundant
4546 calls to mallopt if DOUG_LEA_MALLOC is defined.
4547 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4548 avoid calls to mallopt if zero_vector is returned.
4550 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4552 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4553 is enabled, avoid dereferencing NULL current_sblock if
4556 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4558 Cleanup basic buffer management.
4559 * buffer.h (struct buffer): Change layout to use generic vector
4560 marking code. Fix some comments. Change type of 'clip_changed'
4561 to bitfield. Remove unused #ifndef old.
4562 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4563 (GET_OVERLAYS_AT): Fix indentation.
4564 (for_each_per_buffer_object_at): New macro.
4565 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

4568 * alloc.c (allocate_buffer): Adjust to match new layout of
4569 struct buffer. Fix comment.
4570 (mark_overlay): New function.
4571 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4572 Lisp area of struct buffer.
4573 (mark_object): Use it. Adjust marking of misc objects
4574 and related comments.
4576 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4578 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4579 wrapper that is not needed because the wrapped code is a no-op (zero
4580 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4581 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4583 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4585 * alloc.c (mark_buffer): Simplify. Remove prototype.
4586 (mark_object): Add comment. Reorganize marking of vector-like
4587 objects. Use CHECK_LIVE for all vector-like objects except buffers
4588 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4589 Avoid redundant calls to mark_vectorlike for bool vectors.
4591 2012-06-30 Glenn Morris <rgm@gnu.org>
4593 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4595 * epaths.in (PATH_SITELOADSEARCH): New.
4596 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4597 This is rather than relying on --enable-locallisppath elements
4598 having "site-lisp" in their names. (Bug#10208#25, 11658)
4600 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4602 * w32proc.c (sys_select): Accept and ignore one more argument.
4604 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4606 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4607 (pselect) [!MS_DOS]: Redirect to sys_select.
4609 * sysdep.c: Don't include dos.h and dosfns.h.
4611 * process.c (sys_select):
4612 * msdos.c (sys_select): Accept one more argument and ignore it.
4614 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4615 adapt data types and code to that.
4618 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4619 which clashes with the gnulib function of the same name.
4621 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4623 * font.c (font_style_to_value, font_style_symbolic)
4624 (font_prop_validate_style): Add type checks for values in
4627 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4629 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4632 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4634 * xdisp.c (try_window_id): Undo last change.
4636 * w32.c (getwd): Adjust commentary about startup_dir.
4637 (init_environment): Always call sys_access, even in non-MSVC
4638 builds. Don't chdir to the directory of the Emacs executable.
4639 This undoes code from 1997 which was justified by the need to
4640 "avoid conflicts when removing and renaming directories". But its
4641 downside was that every relative file name was being interpreted
4642 relative to the directory of the Emacs executable, which can never
4643 be TRT. In particular, it broke sys_access when called with
4644 relative file names.
4645 (sys_access): Map GetLastError to errno.
4647 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4649 * window.h (struct window): Change type of 'fringes_outside_margins'

4653 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4656 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

4659 Add QUIT to make the loop interruptible.
4661 2012-06-29 Glenn Morris <rgm@gnu.org>
4663 * charset.c (init_charset): Make lack of etc/charsets fatal.
4665 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4667 * editfns.c (region_limit): Fix type mismatch.
4669 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4671 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4672 undefined. Convert from xassert to eassert.
4673 * nsmenu.m: Convert from xassert to eassert.

4680 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
4682 Avoid integer overflow on scroll-left and scroll-right.
4683 * window.c (HSCROLL_MAX): New macro.
4684 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

4689 * window.h (struct window): Change type of 'hscroll',
4690 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
4691 'last_modified' and 'last_overlay_modified' to EMACS_INT.
4692 Adjust users accordingly.
4693 * xdisp.c (try_cursor_movement): Replace type check with eassert.
4694 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
4695 from EMACS_INT to ptrdiff_t.

4702 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4704 * window.h (struct window): Change type of 'use_time' and

4771 * alloc.c (allocate_string): Omit intervals initialization.
4772 * alloc.c (make_uninit_multibyte_string): Initialize intervals

4831 a better opportunity to optimize away calls to strlen when the
4832 function is called with compile-time constant argument.
4833 * image.c (imagemagick_error): Convert to build_string.
4834 * w32proc.c (sys_spawnve): Likewise.

4837 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
4839 Use sprintf return value instead of invoking strlen on result.
4840 In the old days this wasn't portable, since some sprintf
4841 implementations returned char *. But they died out years ago and
4842 Emacs already assumes sprintf returns int.
4843 Similarly for float_to_string.
4844 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
4845 * ccl.c (ccl_driver):

4851 * xfns.c (syms_of_xfns):
4852 Use sprintf or float_to_string result to avoid need to call strlen.
4853 * data.c (Fnumber_to_string):
4854 Use make_unibyte_string, since the string must be ASCII.
4855 * lisp.h, print.c (float_to_string): Now returns int length.
4856 * term.c (produce_glyphless_glyph):
4857 Use sprintf result rather than recomputing it.
4859 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

4890 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
4892 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

4895 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
4897 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
4898 instead of truncating it to 63 (admittedly a generous limit).
4900 * process.c: Fix spelling and caps in comments.
4902 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
4904 * emacs.c (setpgrp): Remove definition, unused.

5028 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
5030 Support higher-resolution time stamps (Bug#9000).
5031 The time stamps are only nanosecond-resolution at the C level,
5032 since that's the best that any real-world system supports now.
5033 But they are picosecond-resolution at the Lisp level, as that's
5034 easy, and leaves room for future OS improvements.
5036 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5039 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5040 Don't get current time unless it's needed.
5042 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5043 now provides it if it's absent.
5044 (start_atimer): Port to higher-res time stamps.
5045 Check for time stamp overflow. Don't get current time more
5046 often than is needed.
5048 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5049 Include systime.h, not time.h.
5050 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5052 * dired.c: Include stat-time.h.
5053 (Ffile-attributes): File times now have higher resolution.

5056 (struct image): Timestamp now has higher resolution.
5058 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5059 has at least microseconds now. All uses removed.
5060 (update_frame, update_single_window, update_window, update_frame_1)
5061 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5062 (duration_to_sec_usec): Remove; no longer needed.

5071 (make_time): Now static.
5072 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5073 Report an error if the time is invalid, rather than having the caller
5076 * fileio.c: Include <stat-time.h>
5077 (Fcopy_file): Copy higher-resolution time stamps.
5078 Prefer to set the time stamp via a file descriptor if that works.

5080 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5081 (Fvisited_file_modtime, Fset_visited_file_modtime):
5082 Support higher-resolution time stamps.
5084 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5086 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
5088 * image.c (prepare_image_for_display, clear_image_cache)
5089 (lookup_image): Port to higer-resolution time stamps.
5091 * keyboard.c (start_polling, bind_polling_period):
5092 Check for time stamp overflow.
5093 (read_char, kbd_buffer_get_event, timer_start_idle)
5094 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5095 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5096 Port to higher-resolution time stamps. Do not assume time_t is signed.
5097 (decode_timer): New function. Timers are now vectors of length 9,
5098 not 8, to accommodate the picosecond component.
5099 (timer_check_2): Use it.
5101 * nsterm.m (select_timeout, timeval_subtract): Remove.
5102 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5103 as they're a bit more accurate and handle overflow better.
5104 (ns_select): Change prototype to be compatible with pselect.
5105 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5106 * nsterm.h (ns_select): Adjust prototype.
5108 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5109 us-resolution time stamps.
5110 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5112 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5114 * lisp.h (time_overflow): New decl.
5115 (wait_reading_process_output): First arg is now intmax_t, not int,
5116 to accommodate larger waits.
5118 * process.h (struct Lisp_Process.read_output_delay):
5119 Now counts nanoseconds, not microseconds.
5120 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

5125 (Faccept_process_output, wait_reading_process_output):
5126 Check for time stamp overflow. Do not assume time_t is signed.
5127 (select_wrapper): Remove; we now use pselect.
5128 (Fprocess_attributes): Now generates ns-resolution time stamps.
5130 * sysdep.c: Include utimens.h. Don't include utime.h
5131 or worry about struct utimbuf; gnulib does that for us now.
5132 (gettimeofday): Remove; gnulib provides a substitute.
5133 (make_timeval): New function.
5134 (set_file_times): Now sets ns-resolution time stamps.
5135 New arg FD; all uses changed.
5136 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5137 (system_process_attributes):
5138 Now returns ns-resolution time stamp. All uses changed.
5139 Check for time stamp overflow.
5141 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5142 provides a substitute now.
5144 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5145 since it guarantees struct timespec.
5146 (EMACS_TIME): Now struct timespec, so that we can support
5147 ns-resolution time stamps.
5148 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5149 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5150 (EMACS_USECS): Remove.
5151 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5152 so multiply the arg by 1000 before storing it.
5153 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5155 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5156 Port to ns-resolution time stamps.
5157 (EMACS_TIME_NEG_P): Remove; replaced by....
5158 (EMACS_TIME_SIGN): New macro.

5162 (make_timeval, make_lisp_time, decode_time_components): New decls.
5163 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5164 that it mishandled time_t overflow. You can't compare by subtracting!
5165 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5166 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5168 * term.c: Include <sys/time.h>.

5174 (Fprimitive_undo): Use them when restoring time stamps.
5176 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5177 (w32_get_internal_run_time):
5178 Port to higher-resolution Emacs time stamps.
5179 (ltime): Now accepts single 64-bit integer, as that's more convenient
5182 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5184 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5185 for compatibility with pselect. Support ns-resolution time stamps.
5187 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5189 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5190 Check for time stamp overflow, and support ns-resolution time stamps.
5192 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5193 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5194 (timeval_subtract): Remove; no longer needed.
5195 (XTflash, XTring_bell, x_wait_for_event):
5196 Port to ns-resolution time stamps. Don't assume time_t is signed.
5198 2012-06-22 Chong Yidong <cyd@gnu.org>

5202 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5204 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5205 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5206 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5207 staticidx goes up to 1597 out of 1600 = 0x640.)
5209 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
5211 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5212 Otherwise, the umask might be mistakenly 0 while handling input signals.

5246 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
5247 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
5248 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

5257 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
5258 gets killed during executing of this function (Bug#11665).
5259 Try to always return Qt when the buffer has been actually killed.
5260 (Vkill_buffer_query_functions): In doc-string say that functions
5261 run by this hook should not change the current buffer.
5263 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
5265 Fix recently-introduced process.c problems found by static checking.

5283 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
5285 * lisp.h (eassert): Assume C89 or later.
5286 This removes the need for CHECK.
5287 (CHECK): Remove. Its comments about always evaluating its
5288 argument were confusing, as 'eassert' typically does not evaluate
5291 * coding.c (produce_chars): Use ptrdiff_t, not int.
5293 * xterm.c (x_draw_underwave): Check for integer overflow.
5294 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5446 * frame.c (delete_frame): Remove outdated comment.
5447 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
5448 USE_LISP_UNION_TYPE.

5450 (Fw32_toggle_lock_key): Likewise.
5451 * w32menu.c (add_menu_item): Likewise.
5452 (w32_menu_display_help): Use XIL instead of checking

5463 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
5465 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
5467 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
5468 * alloc.c (make_number) [!defined make_number]:
5469 Remove, as lisp.h always defines this now.
5470 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
5471 (roundup_size): Verify that it is a power of 2.
5472 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
5473 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
5474 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
5475 -DUSE_LSB_TAG=0, to override the automatically-selected default.
5476 USE_LSB_TAG now is always defined to be either 0 or 1.
5478 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
5479 code works fine either way, and efficiency is not a concern here,
5480 as the union type is for debugging, not for production.
5481 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
5482 Use an inline function on all platforms when using the union type,
5483 since this is simpler and 'static inline' can be used portably
5485 (LISP_INITIALLY_ZERO): New macro.
5486 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
5487 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

5514 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
5515 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
5516 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

5555 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
5556 dbus_type_is_basic if available.
5557 (xd_extract_signed, xd_extract_unsigned): Rename from
5558 extract_signed and extract_unsigned, respectively. Adapt callers.
5560 2012-06-09 Chong Yidong <cyd@gnu.org>
5562 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).

5569 * xdisp.c (vmessage): Treat frame message as multibyte.
5570 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
5571 would generate the diagnostic "Making \302\247 buffer-local while
5574 2012-06-08 Eli Zaretskii <eliz@gnu.org>
5576 * dispnew.c (showing_window_margins_p): Undo last change, which

5590 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
5592 2012-06-08 Eli Zaretskii <eliz@gnu.org>
5594 * alloc.c (allocate_vectorlike): Fix last change.
5596 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
5598 Block-based vector allocation of small vectors.
5599 * lisp.h (struct vectorlike_header): New field `nbytes',
5600 adjust comment accordingly.
5601 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
5602 to denote vector blocks. Adjust users (live_vector_p,
5603 mark_maybe_pointer, valid_lisp_object_p) accordingly.

5623 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
5625 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
5627 * doprnt.c (doprnt): Truncate multibyte char correctly.
5628 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5629 would mishandle a string argument "Xc" if X was a multibyte
5630 character of length 2: it would truncate after X's first byte
5631 rather than including all of X.
5633 2012-06-06 Chong Yidong <cyd@gnu.org>
5635 * buffer.c (word_wrap): Doc fix.

5684 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5685 Convert pctcpu and pctmem to Lisp float properly.
5686 Let the compiler fold better, as 100.0/0x8000 is exact.
5688 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5690 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5693 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5695 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5697 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5699 For a 'struct window', replace some Lisp_Object fields to
5700 bitfields where appropriate, remove unused fields.
5701 * window.h (struct window): Remove unused 'last_mark_x' and
5702 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5703 change it's type from Lisp_Object to bitfield.
5704 Change type of 'force_start', 'optional_new_start',
5705 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5706 fields from Lisp_Object to bitfield. Adjust users accordingly.
5708 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5710 Pacify gcc -Wdouble-precision when using Xaw.
5711 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5712 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5713 Use 'float' consistently, rather than 'float' in most places
5714 and 'double' in a couple of places.
5716 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5718 * xdisp.c (handle_stop): Detect whether we have overlay strings
5719 loaded by testing it->current.overlay_string_index to be
5720 non-negative, instead of checking whether n_overlay_strings is
5721 positive. (Bug#11587)
5723 2012-05-31 Chong Yidong <cyd@gnu.org>
5725 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5727 * doc.c (Fsubstitute_command_keys): Doc fix.
5729 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5731 * search.c (search_buffer): Remove calls to
5732 r_alloc_inhibit_buffer_relocation, as it is now called by
5733 maybe_unify_char, which was the cause of relocation of buffer text
5736 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5738 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5739 for the duration of call to load_charset, to avoid problems with
5740 callers of maybe_unify_char that access buffer text through C
5743 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5744 decrement the inhibition flag, instead of just setting or
5747 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5749 Remove obsolete '#define static' cruft.
5750 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5751 This #undef was "temporary" in 2000; it is no longer needed
5752 now that '#define static' has gone away.
5753 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5754 (gray_bitmap_bits): Remove; no longer needed.
5755 All uses replaced with definiens.
5756 * xterm.c: Include "bitmaps/gray.xbm".
5758 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5760 Clean up __executable_start, monstartup when --enable-profiling.
5761 The following changes affect the code only when profiling.
5762 * dispnew.c (__executable_start): Rename from safe_bcopy.
5763 Define only on platforms that need it.
5764 * emacs.c: Include <sys/gmon.h> when profiling.
5765 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

5767 (safe_bcopy): Remove decl; no longer has that name.
5768 (main): Coalesce #if into single bit of code, for simplicity.

5796 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
5798 Do not create empty overlays with the evaporate property (Bug#9642).
5799 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
5800 Bug#9642, but explicitly check that the buffer the overlay would
5801 be moved to is live and rearrange lines to make sure that errors
5802 will not put the overlay in an inconsistent state.
5803 (Fdelete_overlay): Cosmetics.
5805 2012-05-28 Eli Zaretskii <eliz@gnu.org>
5807 * w32term.c (my_bring_window_to_top): New function.
5808 (x_raise_frame): Use handle returned by DeferWindowPos, which

5819 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
5821 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
5822 This avoids undefined behavior that might cause the eassert
5823 to not catch an out-of-range value.
5825 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
5827 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

5839 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
5841 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
5842 Only r_alloc_inhibit_buffer_relocation needed to be added;
5843 the others were already declared.
5845 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
5846 before checking whether it's out of range. Put the check inside
5848 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
5850 2012-05-27 Ken Brown <kbrown@cornell.edu>
5852 * callproc.c (Fcall_process): Restore a line that was accidentally
5853 commented out in the 2011-02-13 change (bug#11547).

5857 * lisp.h [REL_ALLOC]: Add prototypes for external functions
5858 defined on ralloc.c.
5860 * buffer.c [REL_ALLOC]: Remove prototypes of
5861 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
5862 they are now on lisp.h.
5864 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
5866 * search.c (search_buffer): Use it to inhibit relocation of buffer
5867 text while re_search_2 is doing its job, because re_search_2 is
5868 passed C pointers to buffer text. (Bug#11519)
5870 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
5873 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
5874 state after an additional call to move_it_in_display_line_to, keep
5875 the values of it->max_ascent and it->max_descent found for the
5877 (pos_visible_p): Revert the comparison against bottom_y to what it
5878 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
5881 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5883 Fix coding-related core dumps with gcc -ftrapv.
5884 The code was computing A - B, where A and B are pointers, and B is
5885 random garbage. This can lead to core dumps on platforms that
5886 have special pointer registers, and it also leads to core dumps on
5887 x86-64 when compiled with gcc -ftrapv. The fix is to compute
5888 A - B only when B is initialized properly.
5889 * coding.c (coding_set_source, coding_set_destination): Return void.
5890 (coding_change_source, coding_change_destinations): New functions,
5891 with the old behaviors of coding_set_source and coding_set_destination.
5892 All callers that need an offset changed to use these new functions.
5894 2012-05-26 Glenn Morris <rgm@gnu.org>
5896 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
5898 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5900 Extend mouse support on W32 text-mode console.
5901 * xdisp.c (draw_row_with_mouse_face):
5902 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
5904 * w32console.c: Include window.h.
5905 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
5907 (initialize_w32_display): Initialize mouse-highlight data.
5909 * w32inevt.c: Include termchar.h and window.h.
5910 (do_mouse_event): Support mouse-autoselect-window. When the mouse
5911 moves, call note_mouse_highlight. If help_echo changed, call
5912 gen_help_event to produce help-echo message in the echo area.
5913 Call clear_mouse_face if mouse_face_hidden is set in the mouse
5916 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5918 * lread.c (read1): Simplify slightly to avoid an overflow warning

5924 definitely wide enough here.
5926 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
5928 Fix integer width and related bugs (Bug#9874).
5929 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):

5939 (allocate_pseudovector):
5940 Use int, not EMACS_INT, where int is wide enough.
5941 (inhibit_garbage_collection, Fgarbage_collect):

5950 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5951 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
5952 (Fkill_buffer, Fset_buffer_major_mode)

5958 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
5959 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
5960 (Foverlay_recenter, last_overlay_modification_hooks_used)
5961 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
5962 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5963 (validate_region): Omit unnecessary test for b <= e,
5964 since that's guaranteed by the previous test.
5965 (adjust_overlays_for_delete): Avoid pos + length overflow.
5966 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
5967 (report_overlay_modification):
5968 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5969 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
5970 Omit pointer cast, which isn't needed anyway, and doesn't work
5971 after the EMACS_INT -> ptrdiff_t change.

5973 * buffer.h: Adjust decls to match defn changes elsewhere.

5978 not int, to avoid needless 32-bit limit on 64-bit hosts.
5979 (exec_byte_code): Use tighter memory-full test, one that checks
5980 for alloca overflow. Don't compute the address of the object just
5981 before an array, as that's not portable. Use EMACS_INT, not
5982 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
5983 * callint.c (Fcall_interactively):
5984 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

5995 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
5996 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5997 (casify_object): Avoid integer overflow when overallocating buffer.
5998 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
5999 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6000 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6001 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6002 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6003 integers are now checked earlier. All uses replaced with XINT.
6005 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6006 For CCL_MapSingle, check that content and value are in int range.
6007 (ccl_driver, Fregister_code_conversion_map):
6008 Check that Vcode_version_map_vector is a vector.
6009 (resolve_symbol_ccl_program): Check that vector header is in range.
6010 Always copy the vector, so that we can check its contents reliably
6011 now rather than having to recheck each instruction as it's being
6012 executed. Check that vector words fit in 'int'.
6013 (ccl_get_compiled_code, Fregister_ccl_program)
6014 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6015 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6016 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6017 contents are in range.
6018 (Fccl_execute_on_string): Check that status is in range.
6019 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6020 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6021 Accept and return EMACS_INT, not int, because callers can pass values
6023 (c_string_width, strwidth, lisp_string_width, chars_in_text)
6024 (multibyte_chars_in_text, parse_str_as_multibyte)
6025 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)

6027 (string_escape_byte8, Fget_byte):
6028 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6029 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6030 avoid mishandling large integers.
6031 * character.h: Adjust decls to match defn changes elsewhere.
6032 * charset.c (load_charset_map_from_file, find_charsets_in_text)

6040 (Fdefine_charset_internal): Check ranges here, more carefully.
6041 Don't rely on undefined behavior with signed left shift overflow.
6042 Don't assume unsigned int fits into fixnum, or that fixnum fits
6043 into unsigned int. Don't require max_code to be a valid fixnum;
6044 that's not true for gb10830 4-byte on a 32-bit host. Allow
6045 invalid_code to be a cons, for the same reason. Require code_offset
6046 to be a character. Avoid int overflow if max_char is close
6048 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6049 this is intended anyway and avoids some undefined behavior.
6050 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6051 INDEX_TO_CODE_POINT, as that's what it expects.
6052 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6053 * charset.h (DECODE_CHAR): Return int, not unsigned;
6054 this is what was intended anyway, and it avoids undefined behavior.
6055 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6056 integer-overflow issues.
6057 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6058 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6059 where the argument is EMACS_INT, and this behavior is not intended.
6060 * chartab.c (Fmake_char_table, Fset_char_table_range)
6061 (uniprop_get_decoder, uniprop_get_encoder):
6062 Don't assume fixnum fits in int.
6063 * cmds.c (move_point): New function, that does the gist of
6064 Fforward_char and Fbackward_char, but does so while checking
6065 for integer overflow more accurately.
6066 (Fforward_char, Fbackward_char): Use it.
6067 (Fforward_line, Fend_of_line, internal_self_insert)
6068 (internal_self_insert):
6069 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6070 Fix a FIXME, by checking for integer overflow when calculating
6071 target_clm and actual_clm.

6728 2012-05-25 Glenn Morris <rgm@gnu.org>
6730 * lisp.mk (lisp): Update for more files being compiled now.
6732 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
6734 * lread.c: Remove `read_pure' which makes no difference.
6735 (read_pure): Remove var.
6736 (unreadpure): Remove function.
6737 (readevalloop): Don't call read_list with -1 flag.

6750 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
6752 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
6755 This directory predates autoconf and is no longer needed nowadays.
6756 Move its few remaining bits of functionality to where they're needed.

6766 (EMACS_UINT): Define unconditionally now.
6767 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
6768 (BITS_PER_EMACS_INT): New constants, replacing
6769 what used to be in config.h, but not useful in #if.
6770 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
6771 define them any more.
6772 (VAL_MAX): New macro.
6774 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
6775 BITS_PER_EMACS_INT, in #if.
6776 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
6777 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
6778 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
6779 * s/ms-w32.h (DATA_START):
6780 Move here from removed file m/intel386.h.
6781 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
6782 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
6784 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
6786 Assume C89 or later.
6787 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

6795 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
6796 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
6797 * xterm.c (input_signal_count): Assume volatile works.
6799 2012-05-21 Ken Brown <kbrown@cornell.edu>
6801 * xgselect.c (xg_select): Fix first argument in call to 'select'
6804 2012-05-20 Ken Brown <kbrown@cornell.edu>
6806 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
6807 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
6809 2012-05-19 Ken Brown <kbrown@cornell.edu>
6811 * xfns.c (x_in_use): Remove `static' qualifier.
6812 * xterm.h (x_in_use): Declare.
6813 * xgselect.c: Include xterm.h.
6814 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
6815 and `display_arg' (bug#9754).
6817 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
6819 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
6821 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
6822 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
6824 2012-05-18 Eli Zaretskii <eliz@gnu.org>
6826 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
6828 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
6829 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
6831 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
6832 reference to image_cache->refcount.
6833 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
6835 2012-05-17 Juri Linkov <juri@jurta.org>
6837 * search.c (Fword_search_regexp, Fword_search_backward)
6838 (Fword_search_forward, Fword_search_backward_lax)
6839 (Fword_search_forward_lax): Move functions to isearch.el
6840 (bug#10145, bug#11381).
6842 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
6844 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
6846 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
6848 * lread.c (init_obarray): Declare Qt and Qnil as special.
6850 2012-05-14 Glenn Morris <rgm@gnu.org>
6852 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
6853 Put "libexec" before "bin", for the sake of init_callproc_1.
6855 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6857 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
6859 * unexaix.c: Port to more-recent AIX compilers.
6860 (report_error, report_error_1, make_hdr, copy_sym)
6861 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
6862 Make arguments const char *, not char *, to avoid violations of C
6863 standard and to fix some AIX warnings reported by Gilles Pion.
6865 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6867 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
6868 already have overlays loaded.
6869 (handle_single_display_spec): Before returning without displaying
6870 fringe bitmap, synchronize the bidi iterator with the main display
6871 iterator, by calling iterate_out_of_display_property.
6872 (iterate_out_of_display_property): Detect buffer iteration by
6873 testing that it->string is a Lisp string.
6874 (get_next_display_element): When the current object is exhausted,
6875 and there's something on it->stack, call set_iterator_to_next to
6876 proceed with what's on the stack, instead of returning zero.
6877 (set_iterator_to_next): If called at the end of a Lisp string,
6878 proceed to consider_string_end without incrementing string
6879 position. Don't increment display vector index past the end of
6880 the display vector. (Bug#11417)
6881 (pos_visible_p): Don't report a position visible when move_it_to
6882 stopped at the last line of window, which happens to be scanned
6883 backwards by the bidi iteration. (Bug#11464)
6885 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6887 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
6888 and right-margin display specs even if the spec is invalid or we
6889 are on a TTY, and thus unable to display on the fringes.
6890 That's because the text with the property will not be displayed anyway,
6891 so we need to signal to the caller that this is a "replacing"
6892 display spec. This fixes display when the spec is invalid or we
6895 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6897 * unexaix.c (make_hdr): Fix typo in prototype.
6898 This bug broke the build on AIX. Problem reported by Gilles Pion.
6900 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
6902 * keyboard.c (kbd_buffer_get_event): Read special events also in
6903 batch mode. (Bug#11415)
6905 2012-05-12 Glenn Morris <rgm@gnu.org>
6907 * ns.mk: Update for ns_appbindir no longer having trailing "/".
6909 2012-05-12 Eli Zaretskii <eliz@gnu.org>
6911 * lisp.mk (lisp): Add newcomment.elc.
6913 2012-05-12 Glenn Morris <rgm@gnu.org>
6915 * Makefile.in (MKDIR_P): New, set by configure.
6916 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
6918 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
6920 Remove unused function hourglass_started.
6921 * dispextern.h (hourglass_started):
6922 * w32fns.c (hourglass_started):
6923 * xdisp.c (hourglass_started): Remove.
6925 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
6927 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
6928 Update dependencies.
6930 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
6932 * xgselect.c (xg_select): Put maxfds+1 into a var.
6933 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
6935 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
6937 2012-05-10 Dave Abrahams <dave@boostpro.com>
6939 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
6940 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
6942 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
6944 * dbusbind.c (xd_registered_buses): New internal Lisp object.
6945 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
6946 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
6947 Initialize xd_registered_buses.
6949 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
6951 Untag more efficiently if USE_LSB_TAG.
6952 This is based on a proposal by YAMAMOTO Mitsuharu in
6953 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
6954 For an admittedly artificial (nth 8000 longlist) benchmark on
6955 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
6956 Emacs's overall text size by 1%.
6957 * lisp.h (XUNTAG): New macro.
6958 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
6959 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
6960 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
6961 * eval.c (Fautoload):
6962 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
6963 * frame.h (XFRAME): Use XUNTAG.
6965 Port recent dbusbind.c changes to 32-bit --with-wide-int.
6966 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
6967 Remove unportable assumptions about print widths of types like
6969 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
6970 intptr_t when converting between pointer and integer, to avoid GCC
6971 warnings about wrong width.
6973 2012-05-09 Eli Zaretskii <eliz@gnu.org>
6975 * w32proc.c (new_child): Force Windows to reserve only 64KB of
6976 stack for each reader_thread, instead of defaulting to 8MB
6977 determined by the linker. This avoids failures in creating
6978 subprocesses on Windows 7, see the discussion in this thread:
6979 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
6981 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
6983 Fix up display of the *Minibuf-0* buffer in the mini window.
6984 * keyboard.c (read_char): Don't clear the echo area if there's no
6986 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
6987 contents of *Minibuf-0*) if there's no message displayed in its stead.
6989 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
6991 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
6994 2012-05-06 Chong Yidong <cyd@gnu.org>
6996 * lisp.mk (lisp): Update.
6998 2012-05-05 Jim Meyering <meyering@redhat.com>
7000 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7002 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7004 * data.c (PUT_ERROR): New macro.
7005 (syms_of_data): Use it. Add new error type `user-error'.
7006 * undo.c (user_error): New function.
7007 (Fprimitive_undo): Use it.
7008 * print.c (print_error_message): Adjust print style for `user-error'.
7009 * keyboard.c (user_error): New function.
7010 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7012 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7014 Do not limit current-time-string to years 1000..9999.
7015 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7016 (Fcurrent_time_string): Support any year that is supported by the
7017 underlying localtime representation. Don't use asctime, as it
7018 has undefined behavior for years outside the range -999..9999.
7020 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7022 Fix race conditions involving setenv, gmtime, localtime, asctime.
7023 Without this fix, interrupts could mess up code that uses these
7024 nonreentrant functions, since setting TZ invalidates existing
7025 tm_zone or tzname values, and since most of these functions return
7026 pointers to static storage.
7027 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7028 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7029 Grow the critical sections to include not just invoking
7030 localtime/gmtime, but also accessing these functions' results
7031 including their tm_zone values if any, and any related TZ setting.
7032 (format_time_string): Last arg is now struct tm *, not struct tm **,
7033 so that the struct tm is saved in the critical section.
7034 All callers changed. Simplify allocation of initial buffer, partly
7035 motivated by the fact that memory allocation needs to be outside
7036 the critical section.

7054 * xdisp.c (pos_visible_p): If already at a newline from the
7055 display string before the 'while' loop, don't walk back the glyphs

7064 2012-05-01 Glenn Morris <rgm@gnu.org>
7066 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7067 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),

7087 Do not avoid creating empty evaporating overlays (Bug#9642).
7088 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7089 That is, do not delete an evaporating overlay if it becomes
7090 empty after its bounds are adjusted to fit within its buffer.
7091 This fix caused other problems, and I'm reverting it until we get
7092 to the bottom of them.
7094 2012-04-27 Chong Yidong <cyd@gnu.org>
7096 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).

7101 ZV, start the display from buffer beginning. Prevents assertion
7102 violation in init_iterator when the minibuffer window is scrolled
7105 * window.c (window_scroll_pixel_based): Likewise.
7107 2012-04-27 Chong Yidong <cyd@gnu.org>

7124 display element, check also the underlying string or buffer
7125 character. (Bug#11341)
7127 * w32menu.c: Include w32heap.h.
7128 (add_menu_item): If the call to AppendMenuW (via
7129 unicode_append_menu) fails, disable Unicode menus only if we are
7130 running on Windows 9X/Me.
7132 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7134 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

7148 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7150 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7151 now a cons (bug#11311).
7153 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7155 Do not create empty overlays with the evaporate property (Bug#9642).
7156 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7157 if it becomes empty after its bounds are adjusted to fit within
7158 its buffer. Without this fix, in a nonempty buffer (let ((o
7159 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7160 yields an empty overlay that has the evaporate property, which is
7161 not supposed to happen.
7163 Fix minor GTK3 problems found by static checking.

7438 against is gone. It's better to use vfork now so that when Cygwin
7439 gains a new, working vfork, we use it automatically (bug#10398).

7496 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7498 * xdisp.c (set_cursor_from_row): If the display string appears in
7499 the buffer at position that is closer to point than the position
7500 after the display string, display the cursor on the first glyph of
7501 the display string. Fixes cursor display when a 'display' text
7502 property immediately follows invisible text. (Bug#11094)
7504 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7506 composite.c: use 'double' consistently
7507 * composite.c (get_composition_id): Use 'double' consistently
7508 instead of converting 'float' to 'double' and vice versa; this is
7509 easier to understand and avoids a GCC warning.
7511 2012-04-09 Glenn Morris <rgm@gnu.org>
7513 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7514 preparation for dumping it with emacs. (Bug#4789)
7515 (leimdir): New variable.
7516 ($(leimdir)/leim-list.el): New rule.
7517 (emacs$(EXEEXT)): Depend on leim-list.el.

7533 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
7535 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
7536 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7537 (mark_memory): Mark Lisp_Objects only if pointers might hide in
7538 objects, as mark_maybe_pointer will catch them otherwise.
7539 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
7540 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
7542 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
7544 Fix typo that broke non-Windows builds.
7545 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

7549 Support building on MS-Windows with libxml2.
7551 * makefile.w32-in (OBJ2): Add xml.$(O).
7552 (GLOBAL_SOURCES): Add xml.c.
7553 ($(BLD)/xml.$(O)): New dependency list.
7555 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
7556 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7557 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7558 [!WINDOWSNT]: New macros.
7559 (init_libxml2_functions, libxml2_loaded_p): New functions.
7560 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7561 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7562 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7563 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7565 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7566 Call init_libxml2_functions before calling libxml2 functions.
7567 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7569 * emacs.c: Don't include libxml/parser.h.
7570 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
7571 xmlCleanupParser directly.
7573 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7575 2012-04-07 Eli Zaretskii <eliz@gnu.org>
7577 * indent.c (Fvertical_motion): If there is a display string at
7578 point, use it.vpos to compute how many lines to backtrack after
7579 move_it_to point. (Bug#11133)
7581 2012-04-06 Eli Zaretskii <eliz@gnu.org>
7583 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7584 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7585 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7586 macros related to unification of CJK characters. For the details,
7587 see the discussion following the message here:
7588 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7590 2012-04-04 Chong Yidong <cyd@gnu.org>
7592 * keyboard.c (Vdelayed_warnings_list): Doc fix.
7594 2012-04-01 Eli Zaretskii <eliz@gnu.org>
7596 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
7597 instead of alloca. (Bug#11138)
7599 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
7601 * w32menu.c (is_simple_dialog): Properly check lisp types.
7604 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7606 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7607 position we get to after a call to move_it_to fails the
7608 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7609 only if we wind up in a string from display property. (Bug#11063)
7611 * window.c (Fdelete_other_windows_internal): Invalidate the row
7612 and column information about mouse highlight, so that redisplay
7613 restores it after reallocating the glyph matrices. (Bug#7464)
7615 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7616 string comes from a `display' text property, use the buffer
7617 position of that property as if we actually saw that position in
7619 (move_it_by_lines): Remove the assertion that
7620 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7621 violated when there's a before-string at the beginning of a line.
7624 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7626 * xdisp.c (append_space_for_newline): If the default face was
7627 remapped, use the remapped face for the appended newline.
7628 (extend_face_to_end_of_line): Use the remapped default face for
7629 extending the face to the end of the line.
7630 (display_line): Call extend_face_to_end_of_line when the default
7631 face was remapped. (Bug#11068)
7633 2012-03-29 Eli Zaretskii <eliz@gnu.org>
7635 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
7637 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
7639 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
7641 2012-03-27 Glenn Morris <rgm@gnu.org>
7643 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
7646 2012-03-26 Kenichi Handa <handa@m17n.org>
7648 * dispextern.h (struct glyph): Fix previous change. Change the
7649 bit length of glyphless.ch to 25 (Bug#11082).
7651 2012-03-26 Chong Yidong <cyd@gnu.org>
7653 * keyboard.c (Vselection_inhibit_update_commands): New variable.
7654 (command_loop_1): Use it; inhibit selection update for
7655 handle-select-window too (Bug#8996).
7657 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7659 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
7661 2012-03-25 Kenichi Handa <handa@m17n.org>
7663 * dispextern.h (struct glyph): Change the bit length of
7664 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7666 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7668 * s/ms-w32.h (tzname): Include time.h before redirecting to
7669 _tzname. Fixes the MSVC build. (Bug#9960)
7671 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
7673 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
7676 * xterm.c (XTread_socket): Only modify handling_signal if
7677 !SYNC_INPUT. (Bug#11080)
7679 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7681 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7682 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7683 when fetching a multibyte character consumes more bytes than
7684 CHAR_BYTES returns, due to unification of CJK characters in
7685 string_char. (Bug#11073)
7687 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7689 * process.c (wait_reading_process_output): Handle pty disconnect
7690 by refraining from sending oneself a SIGCHLD (bug#10933).
7692 2012-03-22 Chong Yidong <cyd@gnu.org>
7694 * dispextern.h (struct it): New member string_from_prefix_prop_p.
7696 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

7705 2012-03-20 Eli Zaretskii <eliz@gnu.org>
7707 * w32proc.c (Fw32_set_console_codepage)
7708 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
7711 2012-03-20 Chong Yidong <cyd@gnu.org>
7713 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
7714 to reflect default non-nil value of redisplay-dont-pause.
7716 2012-03-19 Kenichi Handa <handa@m17n.org>
7718 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
7719 it fit in a valid range (Bug#11003).
7721 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7723 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7724 that is not from display property, accept the row as a "cursor
7725 row" if one of the string's character has a non-nil `cursor'
7726 property. Fixes cursor positioning when there are newlines in
7727 overlay strings, e.g. in icomplete.el. (Bug#11035)
7729 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
7731 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
7733 2012-03-12 Chong Yidong <cyd@gnu.org>
7735 * eval.c (inhibit_lisp_code): Rename from
7736 inhibit_window_configuration_change_hook; move from window.c.
7738 * xfns.c (unwind_create_frame_1, Fx_create_frame):
7739 * window.c (run_window_configuration_change_hook)
7740 (syms_of_window): Callers changed.
7742 2012-03-11 Chong Yidong <cyd@gnu.org>

7751 is visible (Bug#10955).
7753 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
7755 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
7757 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
7759 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
7760 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7763 2012-03-03 Glenn Morris <rgm@gnu.org>
7765 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
7767 2012-03-02 Eli Zaretskii <eliz@gnu.org>
7769 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
7770 position past the first glyph_row that ends at ZV. (Bug#10902)
7771 (redisplay_window, next_element_from_string): Fix typos in
7773 (redisplay_window): Pass to move_it_vertically the margin in
7774 pixels, not in screen lines.
7776 2012-03-02 Glenn Morris <rgm@gnu.org>
7778 * buffer.c (buffer-list-update-hook): Doc fix.
7780 2012-02-29 Eli Zaretskii <eliz@gnu.org>
7782 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
7783 push_it before setting up the iterator for the first overlay
7784 string, even if we have an empty string loaded.
7785 (next_overlay_string): If there's an empty string on the iterator
7786 stack, pop the stack. (Bug#10903)
7788 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
7790 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
7791 Suggested by Stefan Monnier in
7792 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
7793 * alloc.c (widen_to_Lisp_Object): New static function.
7794 (mark_memory): Also mark Lisp_Objects by fetching pointer words
7795 and widening them to Lisp_Objects. This would work even if
7796 USE_LSB_TAG is defined and wide integers are used, which might
7797 happen in a future version of Emacs.
7799 2012-02-25 Chong Yidong <cyd@gnu.org>
7801 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
7804 * xselect.c (Fx_selection_exists_p): Doc fix.
7805 (x_clipboard_manager_save_all): Print an informative message
7806 before saving to clipboard manager.
7808 2012-02-24 Chong Yidong <cyd@gnu.org>
7810 * keyboard.c (process_special_events): Handle all X selection
7811 requests in kbd_buffer, not just the next one (Bug#8869).
7813 2012-02-23 Chong Yidong <cyd@gnu.org>
7815 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
7816 call when setting menu-bar-lines and tool-bar-lines parameters.
7817 (unwind_create_frame_1): New helper function.
7819 * window.c (inhibit_window_configuration_change_hook): New var.
7820 (run_window_configuration_change_hook): Obey it.
7821 (syms_of_window): Initialize it.
7823 2012-02-22 Chong Yidong <cyd@gnu.org>

7830 * fileio.c (Vfile_name_handler_alist): Doc fix.
7832 * buffer.c (Fget_file_buffer): Protect against invalid file
7833 handler return value.

7838 when computing $valmask.
7840 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
7841 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
7842 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
7843 It's useless in that case, and it can cause problems on hosts
7844 that allocate halves of EMACS_INT values separately.
7845 Reported by Dan Horák. Diagnosed by Andreas Schwab in
7846 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
7847 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
7848 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
7849 it avoids undefined behavior on hosts where shifting right by more
7850 than the word width has undefined behavior.
7852 2012-02-19 Chong Yidong <cyd@gnu.org>
7854 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
7855 (Funhandled_file_name_directory, Ffile_name_as_directory)

7858 return values (Bug#10845).
7860 2012-02-18 Eli Zaretskii <eliz@gnu.org>
7862 * .gdbinit (pitx): Fix incorrect references to fields of the
7865 2012-02-17 Chong Yidong <cyd@gnu.org>

7872 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
7874 2012-02-15 Chong Yidong <cyd@gnu.org>
7876 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
7877 marked as special. Also, starting docstrings with * is obsolete.
7879 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
7881 * gnutls.c (emacs_gnutls_write): Fix last change.
7883 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

7892 2012-02-12 Chong Yidong <cyd@gnu.org>
7894 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
7895 as that creates a dangerous corner case.
7897 * window.c (Fdelete_window_internal): Invalidate the mouse
7898 highlight (Bug#9904).
7900 2012-02-12 Glenn Morris <rgm@gnu.org>
7902 * xselect.c (Fx_own_selection_internal)
7903 (Fx_get_selection_internal, Fx_disown_selection_internal)
7904 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
7905 * nsselect.m (Fx_own_selection_internal)
7906 (Fx_disown_selection_internal, Fx_selection_exists_p)
7907 (Fx_selection_owner_p, Fx_get_selection_internal):
7908 Sync docs and argument specs with the xselect.c versions.
7910 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
7912 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
7914 2012-02-11 Eli Zaretskii <eliz@gnu.org>

7930 2012-02-07 Chong Yidong <cyd@gnu.org>
7932 * buffer.c (Fbuffer_local_variables)
7933 (buffer_lisp_local_variables): Handle unbound vars correctly;
7934 don't let Qunbound leak into Lisp.
7936 2012-02-07 Glenn Morris <rgm@gnu.org>
7938 * image.c (Fimagemagick_types): Doc fix.
7940 * image.c (imagemagick-render-type): Change it from a lisp object
7941 to an integer. Move the doc here from the lisp manual.

7944 2012-02-06 Chong Yidong <cyd@gnu.org>
7946 * doc.c (store_function_docstring): Avoid applying docstring of
7947 alias to base function (Bug#2603).

7970 * keyboard.c (adjust_point_for_property): Don't position point
7971 before BEGV. (Bug#10696)
7973 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
7975 Handle overflow when computing char display width (Bug#9496).
7976 * character.c (char_width): Return EMACS_INT, not int.
7977 (char_width, c_string_width): Check for overflow when
7978 computing the width; this is possible now that individual
7979 characters can have unbounded width. Problem introduced
7980 by merge from Emacs 23 on 2012-01-19.
7982 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
7984 * dbusbind.c (Fdbus_register_method): Mention the return value

8502 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
8503 of scroll runs so as to avoid assigning disabled bogus rows and
8504 unnecessary graphics copy operations.
8506 2011-11-27 Eli Zaretskii <eliz@gnu.org>
8508 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

8515 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
8516 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

8544 * xdisp.c (redisplay_window): If cursor row is not fully visible
8545 after recentering, and scroll-conservatively is set to a large
8546 number, scroll window by a few more lines to make the cursor fully
8547 visible and out of scroll-margin. (Bug#10105)
8548 (start_display): Don't move to the next line if the display should
8549 start at a newline that is part of a display vector or an overlay

8633 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
8634 is set, removing the need for VIRT_ADDRESS_VARIES.
8635 (PURE_P): Use a more-efficient implementation that needs just one
8636 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
8637 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
8638 to 4 (xorl, subq, cmpq, setbe).
8639 * alloc.c (pure): Always extern now, since that's the
8640 VIRT_ADDR_VARIES behavior.
8641 (PURE_POINTER_P): Use a single comparison, not two, for
8642 consistency with the new puresize.h.
8643 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

8650 (erase_phys_cursor, update_window_cursor, show_mouse_face)
8651 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8652 behave as if the cursor position were at the window margin.
8654 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8655 and the cursor position is out of bounds, behave as if the cursor
8656 position were at the window margin. (Bug#10075)
8658 2011-11-18 Chong Yidong <cyd@gnu.org>
8660 * window.c (Fwindow_combination_limit): Make first argument

8682 compute_line_metrics.
8683 (compute_line_metrics): Call row_hash, instead of computing the
8686 * dispnew.c (verify_row_hash): Call row_hash for computing the
8687 hash code of a row, instead of duplicating code from xdisp.c.
8689 * dispextern.h (row_hash): Add prototype.
8691 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
8693 * frame.c (delete_frame): Don't delete the terminal when the last

8717 (Vwindow_nest): Rename to Vwindow_combination_limit.
8718 (recombine_windows, make_parent_window, make_window)

8720 (Fset_window_configuration, save_window_save): Rename all
8721 occurrences of window_nest to window_combination_limit.
8723 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
8725 * image.c (imagemagick_load_image): Fix typo.
8727 2011-11-14 Eli Zaretskii <eliz@gnu.org>
8729 * xdisp.c (display_line): Move the call to
8730 highlight_trailing_whitespace before the call to
8731 compute_line_metrics, since the latter needs to see the final
8732 faces of all the glyphs to compute ROW's hash value.
8733 Fixes assertion violations in row_equal_p. (Bug#10035)
8735 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
8737 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

8742 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
8743 with user-defined heap size. Bump the default size of the temacs
8744 heap to 27MB, to avoid memory warning when running temacs.
8745 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
8747 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

8794 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
8796 Avoid some portability problems by eschewing 'extern inline' functions.
8797 The trivial performance wins aren't worth the portability hassles; see
8798 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
8800 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

8802 (window_box_right, window_box_right_offset): Undo previous change,
8803 by removing the "extern"s.
8804 * intervals.c (adjust_intervals_for_insertion)
8805 (adjust_intervals_for_deletion): Undo previous change,
8806 making these static again.
8807 (offset_intervals, temp_set_point_both, temp_set_point)
8808 (copy_intervals_to_string): No longer inline.
8809 * xdisp.c (window_text_bottom_y, window_box_width)

8866 * xmenu.c (cleanup_widget_value_tree): New function.
8867 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

8874 (window_box_width, window_box_left, window_box_left_offset)
8875 (window_box_right, window_box_right_offset): Declare extern.
8876 Otherwise, these inline functions do not conform to C99 and
8877 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
8878 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
8879 * intervals.c (adjust_intervals_for_insertion)
8880 (adjust_intervals_for_deletion): Now extern, because otherwise the
8881 extern inline functions 'offset_intervals' couldn't refer to it.
8882 (static_offset_intervals): Remove.
8883 (offset_intervals): Rewrite using the old contents of
8884 static_offset_intervals. The old version didn't conform to C99
8885 because an extern inline function contained a reference to an
8886 identifier with static linkage.
8888 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
8890 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

8907 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
8908 (Fwindow_vscroll): Doc fix.
8909 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
8910 argument, since it makes no sense to pass a live window and for
8911 consistency with window-child.

8939 (unwind_create_frame): New function (Bug#9943).
8940 (Fx_create_frame): Restructure code to be more similar to the one in
8941 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
8942 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
8943 Move terminal->reference_count++ just before making the frame official
8946 * nsterm.m (x_free_frame_resources): New function.
8947 (x_destroy_window): Move code to x_free_frame_resources.
8949 * xfns.c (unwind_create_frame): Fix comment.

8951 Move terminal->reference_count++ just before making the frame
8952 official. Move initialization of image_cache_refcount and
8953 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
8955 2011-11-05 Eli Zaretskii <eliz@gnu.org>
8957 Support MSVC build with newer versions of Visual Studio.
8958 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as
8959 Nmake barfs on that. Use $(OBJ*_c) variables instead, defined on

8963 which are not supported by MSVC.
8964 (Lisp_Symbol, Lisp_Misc_Any, Lisp_Marker, Lisp_Misc_Overlay)
8965 (Lisp_Save_Value, Lisp_Free): Use ENUM_BF for enumerated types in
8967 (Lisp_Object) [USE_LISP_UNION_TYPE]: Use ENUM_BF for enumerated
8969 (DEFUN) [_MSC_VER]: Define in a different way for MSVC.
8971 * w32fns.c [_MSC_VER]: DECLARE_HANDLE for any MSVC version.
8973 2011-11-05 Fabrice Popineau <fabrice.popineau@supelec.fr> (tiny change)
8975 Support MSVC build with newer versions of Visual Studio.
8976 * w32.c: Don't include w32api.h for MSVC.
8977 (init_environment) [_MSC_VER]: Call sys_access, not _access.

8980 [_MSC_VER]: Include sys/timeb.h, sys/stat.h, and signal.h.
8981 (fstat, stat, utime) [_MSC_VER]: Redirect to their sys_* cousins.
8982 (malloc, free, realloc, calloc) [_MSC_VER]: Always redirect to the
8984 (alloca) [_MSC_VER]: Define to _alloca.
8986 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
8988 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
8990 2011-11-04 Eli Zaretskii <eliz@gnu.org>
8992 * xdisp.c (note_mouse_highlight): If either of
8993 previous/next-single-property-change returns nil, treat that as
8994 the beginning or the end of the buffer. (Bug#9955)
8996 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
8998 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
8999 label is not null (Bug#9951).

9014 * xfns.c (unwind_create_frame): Likewise.
9016 2011-11-01 Eli Zaretskii <eliz@gnu.org>
9018 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
9019 Don't stop backward scan on the continuation glyph, even though
9020 its CHARPOS is positive.
9021 (mouse_face_from_buffer_pos, note_mouse_highlight):
9022 Rename cover_string to disp_string.
9024 2011-11-01 Martin Rudalics <rudalics@gmx.at>
9026 * window.c (temp_output_buffer_show): Don't use
9027 Vtemp_buffer_show_specifiers.
9028 (Vtemp_buffer_show_specifiers): Remove unused variable.
9030 2011-10-30 Eli Zaretskii <eliz@gnu.org>
9032 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
9033 past the beginning of the current glyph matrix.
9035 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
9037 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
9038 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
9039 HAVE_GTK3 (Bug#9869).

9042 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
9044 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
9046 * xterm.c: Declare x_handle_net_wm_state to return int.

9055 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
9057 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
9058 so that this new function doesn't get optimized away by a
9059 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
9061 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9063 * frame.h (MOUSE_HL_INFO): Remove excess parens.
9065 2011-10-29 Eli Zaretskii <eliz@gnu.org>
9067 Fix the `xbytecode' command.
9068 * .gdbinit (xprintbytestr): New command.
9069 (xwhichsymbols): Rename from `which'; all callers changed.
9070 (xbytecode): Print the byte-code string as well.
9072 2011-10-29 Kim Storm <storm@cua.dk>
9074 * alloc.c (which_symbols): New function.
9076 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9078 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
9081 2011-10-29 Glenn Morris <rgm@gnu.org>
9083 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
9084 Not clear what it was for, and it causes various bugs. (Bug#9839)
9086 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9088 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
9089 possible random value that matches one of those tested as
9090 condition to clear the mouse face.
9092 2011-10-28 Chong Yidong <cyd@gnu.org>
9094 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
9096 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
9098 * window.c (make_window): Initialize phys_cursor_on_p.
9100 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
9102 * lisp.h (struct Lisp_Symbol): Update comments.
9104 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
9106 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
9108 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9110 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
9111 <oslsachem@gmail.com> for helping to debug this.
9113 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
9114 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
9115 (g_b_init_get_glyph_outline_w): New static variables.
9116 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
9117 (GetGlyphOutlineW_Proc): New typedefs.
9118 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
9119 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
9121 (w32font_open_internal, compute_metrics):
9122 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
9123 instead of calling the "wide" APIs directly.
9125 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
9127 * w32.h (syms_of_w32font): Add prototype.
9129 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9131 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
9132 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
9133 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
9134 (Fmove_to_window_line): Doc fix.
9136 2011-10-27 Chong Yidong <cyd@gnu.org>
9138 * process.c (make_process): Set gnutls_state to NULL.
9140 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
9141 non-NULL, regardless of GNUTLS_INITSTAGE.
9142 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
9143 an error. Set process slots as soon as we allocate them.
9145 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9147 2011-10-27 Chong Yidong <cyd@gnu.org>

9151 (Fgnutls_deinit, Fgnutls_boot): Use it.
9153 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9154 (deactivate_process): Call emacs_gnutls_deinit.
9156 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

9159 * w32.c (sys_rename, w32_delayed_load):
9160 * w32font.c (fill_in_logfont):
9161 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9163 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9165 * w32fns.c (w32_default_color_map): New function,
9166 extracted from Fw32_default_color_map.
9167 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9169 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9171 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9173 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9175 * keyboard.c (test_undefined): New function (bug#9751).
9176 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9178 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9180 * sysdep.c (init_sys_modes): Fix the check for the controlling
9181 terminal (Bug#6649).
9183 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9185 * dispextern.h (struct bidi_it): New member next_en_type.
9187 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9188 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9189 current character, check also for next_en_type being WEAK_EN.
9190 (bidi_resolve_weak): Don't enter the expensive loop if the current
9191 position is before next_en_pos. Record the bidi type of the first
9192 non-ET, non-BN character we find, in addition to its position.
9193 (bidi_level_of_next_char): Invalidate next_en_type when
9194 next_en_pos is over-stepped.
9196 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9198 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9199 * editfns.c: Rewrite current-time-zone so that it invokes
9200 the equivalent of (format-time-string "%Z") to get the time zone name.
9201 This fixes a bug when the time zone name contains characters that
9202 need converting from the system time locale to Emacs internal format.
9203 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9204 that patch fixed format-time-string to do the conversion, but
9205 I forgot to fix current-time-zone.
9206 (format_time_string): New function, containing most of
9207 what Fformat_time_string used to contain.
9208 (Fformat_time_string): Rewrite in terms of format_time_string.
9209 This doesn't change this function's behavior.
9210 (current-time-zone): Rewrite to use format_time_string.
9211 This fixes the bug reported by Michael Schierl in
9212 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9213 Jason Rumney's 2007-06-07 change worked around this bug, but
9215 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9217 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9219 * xdisp.c (start_display): If the character at POS is displayed
9220 via a display vector, reset IT->current.dpvec_index to zero.
9221 (try_window_reusing_current_matrix): If a line ends in a display
9222 vector or the next line starts in a display vector, continue
9223 redrawing the window even though the character position of
9224 start_row was reached.
9227 2011-10-18 Chong Yidong <cyd@gnu.org>
9229 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9230 with nobreak-char-display too.
9232 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9234 Fix part 3 of bug#9771.
9235 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9236 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9237 non-neutral characters if the current character is a paragraph
9238 separator (a.k.a. Newline). This avoids running the same
9239 expensive loop twice, once when we consume the preceding newline
9240 and the other time when the line actually needs to be displayed.
9241 Avoid the loop when we see neutrals on the base embedding level
9242 following a character whose directionality is the same as the
9243 paragraph's. This avoids running the expensive loop when a line
9244 ends in a long sequence of neutrals, like control characters.
9245 Add assertion against STRONG_AL type. Slightly rearrange code
9246 that determines the type of a neutral given the first non-neutral
9248 (bidi_level_of_next_char): Set next_en_pos to zero when
9249 invalidating its info.
9251 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9253 * xdisp.c (push_display_prop): Determine whether to record string
9254 or buffer position by IT->string, not by IT->method. Allow
9255 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9256 (move_it_vertically_backward): Don't look for character position
9257 immediately after the newline when in a continuation line.
9260 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9262 * window.c (coordinates_in_window): Rewrite and delabelize
9263 vertical border check. (Bug#5357) (Bug#9618)
9265 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9267 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9268 errors in XSetWindowBorder (bug#9310).
9270 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9272 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9273 avoid crash when xmalloc overrun checking is enabled.
9275 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9277 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9278 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9279 cursor motion with <left> and <right> arrow keys.
9281 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9282 some callers set that themselves.
9284 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9286 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9287 display string and the previous row comes from the same string and
9288 is empty. (Bug#9739) (Bug#9738)
9290 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9292 * doc.c (get_doc_string): Encode file name (bug#9735).
9294 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9296 * bidi.c (bidi_level_of_next_char):
9297 * xdisp.c (get_visually_first_element): Remove old incorrect
9298 comments regarding the Unicode Line Separator character.
9300 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9302 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9304 * alloc.c (Fgc_status): Do not access beyond zombies array
9305 boundary if nzombies > MAX_ZOMBIES.
9306 * alloc.c (dump_zombies): Add missing format specifier.
9308 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9310 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9311 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9313 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9314 Some packages use them to denote characters with modifiers.
9316 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9318 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9319 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9320 matching a pp-number. Rename parameter var to var1.
9322 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9324 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9326 2011-10-08 Glenn Morris <rgm@gnu.org>
9328 * callint.c (Fcall_interactively): Give a more explicit error for the
9329 'c' case with a non-character input. (Bug#8479)
9331 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9333 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9335 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9336 lines that are hscrolled on the left.
9338 * dispnew.c (buffer_posn_from_coords): Account for a possible
9339 presence of header-line. (Bug#4426)
9341 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9343 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9344 Don't advertise functionality which we discourage or doesn't work.
9346 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9348 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9349 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9350 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9351 this makes Emacs dump core during garbage collection on rare
9352 occasions. sizeof is obviously inferior to offsetof here, so
9353 stick with offsetof.
9354 (GC_POINTER_ALIGNMENT): New macro.
9355 (mark_memory): Omit 3rd (offset) arg; caller changed.
9356 Don't assume EMACS_INT alignment is the same as pointer alignment.
9358 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9360 * keyboard.c (read_key_sequence_remapped): New var.
9361 (read_key_sequence): Compute remapping in the right buffer.
9362 (command_loop_1): Use read_key_sequence's remapping directly.
9364 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9366 * dired.c (file_name_completion): Don't expand file name.
9367 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9368 before checking file name handler.
9370 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9371 they've been requested explicitly (bug#9591).
9373 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9375 * keymap.c (Fsingle_key_description): Use make_specified_string
9376 instead of build_string to build string from push_key_description.
9379 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9381 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9382 This fixes a Y2038 bug on 64-bit hosts.
9383 * buffer.c (reset_buffer):
9384 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9385 (Fclear_buffer_auto_save_failure):
9386 Use 0, not -1, to represent an unset failure time, since time_t
9387 might not be signed.
9389 Remove dependency on glibc malloc internals.
9390 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9391 Move back here from lisp.h, but with their new implementations.
9392 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9393 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9394 * charset.c (charset_table_init): New static var.
9395 (syms_of_charset): Use it instead of xmalloc. This removes a
9396 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9397 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9398 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9399 Move back to alloc.c.
9400 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9401 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9403 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9405 * nsterm.m (windowDidResize): Call x_set_window_size only when
9406 ns_in_resize is true. Otherwise set pixelwidth/height and
9407 call change_frame_size (Bug#9628).
9409 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9411 Port --enable-checking=all to Fedora 14 x86-64.
9412 * charset.c (syms_of_charset): Also account for glibc malloc's
9413 internal overhead when calculating the initial malloc maximum.
9415 Port --enable-checking=all to Fedora 14 x86.
9416 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9418 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9419 (overrun_check_realloc, overrun_check_free):
9420 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9421 That way, xmalloc returns a properly-aligned pointer even if
9422 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9423 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9424 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9425 into account when calculating the initial malloc maximum.
9426 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9427 Move here from alloc.c, so that charset.c can use it too.
9428 Properly align; the old code wasn't right for common 32-bit hosts
9429 when configured with --enable-checking=all.
9430 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9431 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.

9440 * xdisp.c (compute_display_string_end): If there's no display
9441 string at CHARPOS, return -1.
9443 * bidi.c (bidi_fetch_char): When compute_display_string_end
9444 returns a negative value, treat the character as a normal
9445 character not covered by a display string. (Bug#9624)
9447 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9449 * lread.c (Fread_from_string): Fix typo in docstring.
9451 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9453 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9454 newline, reseat the iterator instead of bidi-iterating there one
9455 character at a time. (Bug#9610)
9456 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9457 TO_CHARPOS if the bidi iterator is at base embedding level.
9459 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9461 * lread.c (readevalloop): Use correct code for NBSP.
9462 (read1): Likewise. (Bug#9608)
9464 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9466 * dbusbind.c (Fdbus_register_signal): When service is not
9467 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9469 2011-09-25 Glenn Morris <rgm@gnu.org>
9471 * buffer.c (truncate-lines): Doc fix.
9473 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

9488 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9490 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9491 Default value is now t. Doc fix.
9493 * indent.c (Fvertical_motion): Compute and apply the overshoot
9494 logic when moving up, not only when moving down. Fix the
9495 confusing name and values of the it_overshoot_expected variable;
9496 logic changes accordingly. (Bug#9254) (Bug#9549)
9498 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9499 CHARPOS is covered by a display string which includes newlines.
9500 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9501 is covered by a display string with embedded newlines.
9503 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9505 * dbusbind.c (Fdbus_register_signal): Add match rule to
9506 Vdbus_registered_objects_table. (Bug#9581)
9507 (Fdbus_register_method, Vdbus_registered_objects_table):
9510 2011-09-24 Jim Meyering <meyering@redhat.com>
9512 do not ignore write error for any output size
9513 The previous change was incomplete.
9514 While it makes emacs --batch detect the vast majority of stdout
9515 write failures, errors were still ignored whenever the output size is
9516 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9517 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9518 && echo FAIL: ignored write error
9519 FAIL: ignored write error
9520 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \

9525 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9527 * emacs.c (Fkill_emacs): In noninteractive mode exit
9528 non-successfully if a write error occurred on stdout. (Bug#9574)
9530 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9532 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9535 * dispextern.h (struct it): Update the comment documenting what
9538 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9540 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9541 a display string, extend search for cursor position to end of row.
9542 (find_row_edges): If the row ends in a newline from a display
9543 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9544 Handle the case of a display string with multiple newlines.
9545 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9546 non-empty line. Fixes confusing cursor motion with arrow keys at
9547 the beginning of a line that starts with whitespace.
9549 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9551 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9554 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9556 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9559 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9561 * xdisp.c (display_line): Record maximum and minimum buffer
9562 positions even if no glyphs were produced (e.g., by a zero-width
9563 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9564 buffer positions that will be removed from the glyph row because
9566 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9567 column is beyond frame width: don't subtract 1 "pixel" when
9568 computing width of the stretch.
9569 (reseat_at_next_visible_line_start): Undo the change made on
9570 2011-09-17 that saved paragraph information and restored it after
9571 the call to `reseat'. (Bug#9545)
9573 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9575 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9576 and turn window cursor on if cleared (Bug#9415).

9580 * search.c (boyer_moore): Take unibyte characters from pattern
9581 literally. (Bug#9458)
9583 2011-09-18 Eli Zaretskii <eliz@gnu.org>

9587 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9589 Fix minor problem found by static checking.
9590 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9591 initialized, to pacify gcc -Wuninitialized.
9593 * fileio.c: Report proper errno when syscall falls.
9594 (Finsert_file_contents): Save and restore errno,
9595 so that report_file_error outputs the correct diagnostic.
9596 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9598 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9600 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9602 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9604 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9605 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9607 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9609 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9610 about the current paragraph and restore it after the call to reseat.
9612 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9613 (bidi_find_paragraph_start): Search back for paragraph beginning
9614 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9615 (bidi_move_to_visually_next): Only trigger paragraph-related
9616 computations when the last character is a newline or at EOB, not
9617 just any NEUTRAL_B. (Bug#9470)
9619 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9620 truncated lines if point is covered by a display string. (Bug#9524)
9622 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9624 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9625 (cons_to_x_long): New function.
9626 (lisp_data_to_selection_data): Use it. Correct the test for
9627 short-versus-long data; it was negated. Break out of vector
9628 loop, for efficiency, when a long datum is discovered.
9630 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9632 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9634 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9636 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9637 GCC PR/17406) by declaring this function with external scope.
9639 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9641 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

9644 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9646 * editfns.c (Fformat): Correctly handle text properties on "%%".

9656 of TAB characters in a composition.
9658 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9660 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9661 This occurs when processing a multibyte format.
9662 Problem reported by Wolfgang Jenker.
9664 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9666 * xdisp.c (try_cursor_movement): Only check for exact match if
9667 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9669 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9671 Remove unused external symbols.
9672 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9673 * xdisp.c (calc_pixel_width_or_height): Now static.
9674 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9675 * indent.c (check_display_width):
9676 * w32term.c: Fix comment to match code.
9677 * xterm.c, xterm.h (x_catching_errors): Remove.
9679 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9681 * xselect.c: Use signed conversions more consistently (Bug#9498).
9682 (selection_data_to_lisp_data): Assume incoming selection data are
9683 signed integers, not unsigned. This is to be consistent with
9684 outgoing selection data, which was modified to use signed integers
9685 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9686 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9687 expects long, not unsigned long.
9689 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9691 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9692 computation of loop end. Reported by Johan Bockgård
9695 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9697 * frame.c (Fother_visible_frames_p): Function deleted.
9699 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9701 * indent.c (compute_motion): Process display vector front to back
9702 rather than the other way around. (Bug#2496)
9704 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9706 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9708 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9710 * minibuf.c (Fread_from_minibuffer): Doc fix.
9712 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9714 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9715 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9717 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9719 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9720 value for non-existent files.
9722 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9724 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9725 set its "size" to -1. This will set the modtime_size field of
9726 the corresponding buffer to -1, which is what
9727 verify-visited-file-modtime expects for files that do not exist.
9730 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9732 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9734 * lisp.h: ... from here. push_key_description is no longer
9735 defined in keyboard.c, so its declaration should not be in
9736 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9737 logically belongs with push_key_description.
9739 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9741 * buffer.h: Include <sys/types.h> instead of <time.h>.
9742 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9743 Problem reported by Herbert J. Skuhra.
9745 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9747 * xml.c (parse_region): Make the parsing work for
9748 non-comment-starting XML files again (bug#9144).
9750 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9752 * image.c (gif_load): Fix calculation of bottom and right corner.
9755 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9757 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9758 redisplay in small windows.
9760 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9762 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9764 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9766 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9767 Operate on live windows only.
9769 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
9771 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
9773 2011-09-07 Eli Zaretskii <eliz@gnu.org>
9775 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
9776 only under bidi iteration.
9778 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
9780 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9782 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9784 isnan: Fix porting problem to Solaris 10 with bundled gcc.
9785 Without this fix, the command to link temacs failed due to an
9786 undefined symbol __builtin_isnan. This is because
9787 /usr/include/iso/math_c99.h #defines isnan(x) to
9788 __builtin_isnan(x), but the bundled gcc, which identifies itself
9789 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
9791 * floatfns.c (isnan): #undef, and then #define to a clone of
9793 (Fisnan): Always define, since it's always available now.
9794 (syms_of_floatfns): Always define isnan at the Lisp level.
9796 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9798 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
9800 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9802 * fileio.c: Fix bugs with large file offsets (Bug#9428).
9803 The previous code assumed that file offsets (off_t values) fit in
9804 EMACS_INT variables, which is not true on typical 32-bit hosts.
9805 The code messed up by falsely reporting buffer overflow in cases
9806 such as (insert-file-contents "big" nil 1 2) into an empty buffer
9807 when "big" contains more than 2**29 bytes, even though this
9808 inserts just one byte and does not overflow the buffer.
9809 (Finsert_file_contents): Store file offsets as off_t
9810 values, not as EMACS_INT values. Check for overflow when
9811 converting between EMACS_INT and off_t. When checking for
9812 buffer overflow or for overlap, take the offsets into account.
9813 Don't use EMACS_INT for small values where int suffices.
9814 When checking for overlap, fix a typo: ZV was used where
9815 ZV_BYTE was intended.
9816 (Fwrite_region): Don't assume off_t fits into 'long'.
9817 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
9819 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
9821 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
9823 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9825 sprintf-related integer and memory overflow issues (Bug#9412).
9827 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
9828 (esprintf, exprintf, evxprintf): New functions.
9829 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
9830 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
9831 (modify_event_symbol): Do not assume that the length of
9832 name_alist_or_stem is safe to alloca and fits in int.
9833 (Fexecute_extended_command): Likewise for function name and binding.
9834 (Frecursion_depth): Wrap around reliably on integer overflow.
9835 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
9836 since some callers pass EMACS_INT values.
9837 (Fsingle_key_description): Don't crash if symbol name contains more
9838 than MAX_ALLOCA bytes.
9839 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
9840 (get_minibuffer): Arg is now EMACS_INT, not int.
9841 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
9842 (esprintf, exprintf, evxprintf): New decls.
9843 * window.h (command_loop_level, minibuf_level): Reflect API changes.
9845 * dbusbind.c (signature_cat): New function.
9846 (xd_signature, Fdbus_register_signal):
9847 Do not overrun buffer; instead, report string overflow.
9849 * dispnew.c (add_window_display_history): Don't overrun buffer.
9850 Truncate instead; this is OK since it's just a log.
9852 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
9853 even if the time zone offset is outlandishly large.
9854 Don't mishandle offset == INT_MIN.
9856 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
9857 when creating daemon; the previous buffer-overflow check was incorrect.
9859 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
9860 which has the guts of the old verror function.
9862 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
9863 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
9865 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
9866 (font_unparse_xlfd): Don't blindly alloca long strings.
9867 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
9868 fits in int, when using sprintf. Use single snprintf to count
9869 length of string rather than counting it via multiple sprintfs;
9870 that's simpler and more reliable.
9871 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
9872 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
9873 sprintf, in case result does not fit in int.
9875 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
9876 (fontset_from_font): Print it.
9878 * frame.c (tty_frame_count): Now printmax_t, not int.
9879 (make_terminal_frame, set_term_frame_name): Print it.
9880 (x_report_frame_params): In X, window IDs are unsigned long,
9881 not signed long, so print them as unsigned.
9882 (validate_x_resource_name): Check for implausibly long names,
9883 and don't assume name length fits in 'int'.
9884 (x_get_resource_string): Don't blindly alloca invocation name;
9885 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
9888 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
9889 (xg_check_special_colors, xg_set_geometry):
9890 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
9892 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
9893 Use esprintf, not sprintf, in case result does not fit in int.
9895 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9896 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
9897 it as a large positive number.
9898 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
9899 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9901 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
9902 in case result does not fit in int.
9904 * print.c (float_to_string): Detect width overflow more reliably.
9905 (print_object): Make sprintf buffer a bit bigger, to avoid potential
9906 buffer overrun. Don't assume list length fits in 'int'. Treat
9907 print length of 0 as 0, not as infinity; to be consistent with other
9908 uses of print length in this function. Don't overflow print length
9909 index. Don't assume hash table size fits in 'long', or that
9910 vectorlike size fits in 'unsigned long'.
9912 * process.c (make_process): Use printmax_t, not int, to format
9913 process-name gensyms.
9915 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
9917 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
9918 to avoid potential buffer overrun.
9920 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
9921 if X resource line is longer than 512 bytes.
9923 * xfns.c (x_window): Make sprintf buffer a bit bigger
9924 to avoid potential buffer overrun.
9926 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
9928 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
9930 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9932 Integer overflow fixes for scrolling, etc.
9933 Without these, Emacs silently mishandles large integers sometimes.
9934 For example, "C-u 4294967297 M-x recenter" was treated as if
9935 it were "C-u 1 M-x recenter" on a typical 64-bit host.
9937 * xdisp.c (try_window_id): Check Emacs fixnum range before
9938 converting to 'int'.
9940 * window.c (window_scroll_line_based, Frecenter):
9941 Check that an Emacs fixnum is in range before assigning it to 'int'.
9942 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
9943 values converted from Emacs fixnums.
9944 (Frecenter): Don't wrap around a line count if it is out of 'int'
9945 range; instead, treat it as an extreme value.
9946 (Fset_window_configuration, compare_window_configurations):
9947 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
9949 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
9950 that can exceed INT_MAX. Check that EMACS_INT value is in range
9951 before assigning it to the (possibly-narrower) index.
9952 (match_limit): Don't assume that a fixnum can fit in 'int'.
9954 * print.c (print_object): Use ptrdiff_t, not int, for index that can
9957 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
9958 (Fvertical_motion): Don't wrap around LINES values that don't fit
9959 in 'int'. Instead, treat them as extreme values. This is good
9960 enough for windows, which can't have more than INT_MAX lines anyway.
9962 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9964 * Require libxml/parser.h to avoid compilation warning.
9966 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
9968 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
9969 since this reportedly can destroy thread storage.
9971 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
9973 * syntax.c (find_defun_start): Update all cache variables if
9974 exiting early (Bug#9401).
9976 2011-08-30 Eli Zaretskii <eliz@gnu.org>
9978 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
9980 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
9981 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
9982 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
9984 * term.c (tty_append_glyph): New function.
9985 (produce_stretch_glyph): Static function and its prototype deleted.
9987 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
9990 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
9992 * image.c (parse_image_spec): Check for nonnegative, not for positive,
9993 when checking :margin (Bug#9390).
9994 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
9995 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
9996 so that the name doesn't mislead. All uses changed.
9998 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10000 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10003 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10005 * xdisp.c (move_it_to): Don't bail out early when reaching
10006 position beyond to_charpos, if we are scanning backwards.
10007 (move_it_vertically_backward): When DY == 0, make sure we get to
10008 the first character in the line after the newline.
10010 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10012 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10013 (ccl_driver): Do not generate an out-of-range pointer.
10014 (Fccl_execute_on_string): Remove unnecessary check for
10015 integer overflow, noted by Stefan Monnier in
10016 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10017 Remove a FIXME that didn't need fixing.
10018 Simplify the newly-introduced buffer reallocation code.
10020 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10022 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10024 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10026 Integer and memory overflow issues (Bug#9196).
10028 * doc.c (get_doc_string): Rework so that
10029 get_doc_string_buffer_size is the actual buffer size, rather than
10030 being 1 less than the actual buffer size; this makes xpalloc more
10033 * image.c (x_allocate_bitmap_record, cache_image):
10034 * xselect.c (Fx_register_dnd_atom):
10035 Simplify previous changes by using xpalloc.
10037 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10038 since either will do and ptrdiff_t is convenient with xpalloc.
10040 * charset.c (charset_table_size)
10041 (struct charset_sort_data.priority): Now ptrdiff_t.
10042 (charset_compare): Don't overflow if priorities differ greatly.
10043 (Fsort_charsets): Don't assume list length fits in int.
10044 Check for size-calculation overflow when allocating sort data.
10045 (syms_of_charset): Allocate an initial charset table that is
10046 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10048 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10050 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10051 The actual value is always <= INT_MAX, and leaving it unsigned made
10052 overflow checking harder.
10054 * dispextern.h (struct glyph_matrix.rows_allocated)
10055 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10056 with xpalloc. The values are still always <= INT_MAX.
10058 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10060 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10061 (SAFE_NALLOCA): New macro.
10063 * region-cache.c (struct boundary.pos, find_cache_boundary)
10064 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10065 (set_cache_region, invalidate_region_cache)
10066 (revalidate_region_cache, know_region_cache, region_cache_forward)
10067 (region_cache_backward, pp_cache):
10068 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10069 so that ptrdiff_t * can be passed to xpalloc.
10070 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10071 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10072 (pp_cache): Don't assume cache_len fits in int.
10073 * region-cache.h: Adjust extern decls to match.
10075 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10076 EMACS_INT, since either will do, for xpalloc.
10078 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10079 (xnmalloc, xnrealloc, xpalloc): New functions.
10081 * bidi.c (bidi_shelve_header_size): New constant.
10082 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10083 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10085 * bidi.c (bidi_cache_shrink):
10086 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10088 Don't update size of array until after memory allocation succeeds,
10089 because xmalloc/xrealloc may not return.
10090 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10091 now that we have proper integer overflow checking.
10092 (record_overlay_string, overlay_strings): Catch overflows when
10093 calculating size of overlay_str_buf.
10095 * callproc.c (Fcall_process): Check for size overflow when
10096 calculating size of args2.
10097 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10098 Normally we prefer signed values, but sticking with ptrdiff_t would
10099 require adding more-complicated checks.
10101 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10102 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10103 Redo buffer-overflow calculations to avoid integer overflow.
10104 Add a FIXME comment where memory seems to be over-allocated.
10106 * character.c (Fstring): Check for size-calculation overflow.
10108 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10109 unnecessary integer overflow. Check for size overflow.
10110 (encode_coding_object): Don't update size until xmalloc succeeds.
10112 * composite.c (get_composition_id): Check for overflow in glyph
10113 length calculations.
10115 Integer and memory overflow fixes for display code.
10116 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10117 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10118 (scrolling_window): Check for overflow in size calculations.
10119 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10120 Don't assume glyph table len fits in int.

10122 (row_table_size): Now ptrdiff_t, not int.
10123 (scrolling_window): Avoid overflow in size calculations.
10124 Don't update size until allocation succeeds.
10125 * fns.c (concat): Check for overflow in size calculations.
10126 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.

10130 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10131 (get_doc_string): Check for size calculation overflow.
10132 Don't update size until allocation succeeds.
10133 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
10134 EMACS_INT, where ptrdiff_t will do.
10135 (Fsubstitute_command_keys): Check for string overflow.
10137 * editfns.c (set_time_zone_rule): Don't assume environment length
10139 (message_length): Now ptrdiff_t, not int.
10140 (Fmessage_box): Don't update size until allocation succeeds.
10141 Don't assume message length fits in int.
10142 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10144 * emacs.c (main): Do not reallocate argv, since there is a null at
10145 the end that can be overwritten, and this way there's no need to
10146 worry about size-calculation overflow.
10147 (sort_args): Check for size-calculation overflow.
10149 * eval.c (init_eval_once, grow_specpdl): Don't update size until
10151 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
10153 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
10154 (x_set_scroll_bar_width, x_figure_window_size):
10155 Check for integer overflow.
10156 (x_set_alpha): Do not assume XINT fits in int.
10158 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10159 This is for the members text_lines, text_cols, total_lines, total_cols,
10160 where the system imposes an 'int' limit.
10162 * fringe.c (Fdefine_fringe_bitmap):
10163 Don't update size until alloc works.
10165 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
10166 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
10168 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10169 Check for size-calculation overflow.
10170 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10171 do, as we prefer signed integers.
10172 (id_to_widget.max_size, id_to_widget.used)
10173 (xg_store_widget_in_map, xg_remove_widget_from_map)
10174 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
10175 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
10176 Use and return ptrdiff_t, not int.
10177 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
10178 * gtkutil.h: Change prototypes to match the above.
10180 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
10181 are duplicate now that they've been promoted to lisp.h.
10182 (x_allocate_bitmap_record, x_alloc_image_color)
10183 (make_image_cache, cache_image, xpm_load):
10184 Don't update size until alloc is done.
10185 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
10187 Check for size calculation overflow.
10188 (ct_colors_allocated_max): New constant.
10189 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
10192 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
10193 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
10194 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
10195 Use ptrdiff_t, not int, to count maps.
10196 (read_char_minibuf_menu_prompt): Check for overflow in size
10197 calculations. Don't update size until allocation succeeds.
10198 Redo calculations to avoid overflow.
10199 * keyboard.h: Change prototypes to match the above.
10201 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
10203 (current_minor_maps): Check for size calculation overflow.
10204 * keymap.h: Change prototypes to match the above.
10206 * lread.c (read1, init_obarray): Don't update size until alloc done.
10208 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
10209 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
10211 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
10212 Now ptrdiff_t, not int.
10213 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

10219 * region-cache.c (move_cache_gap): Check for size calculation overflow.
10221 * scroll.c (do_line_insertion_deletion_costs): Check for size calc

10224 * search.c (Freplace_match): Check for size calculation overflow.
10225 (Fset_match_data): Don't assume list lengths fit in 'int'.
10227 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
10228 for command line length. Do not attempt to address one before the
10229 beginning of an array, as that's not portable.
10231 * term.c (max_frame_lines): Remove; unused.
10232 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
10234 (encode_terminal_code, calculate_costs): Check for size
10235 calculation overflow.

10238 done. Redo calculations to avoid overflow.
10239 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
10241 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
10242 subtracting pointers.
10243 (gobble_line): Check for overflow more carefully. Don't update size
10246 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

10257 Use ptrdiff_t, not int, for sizes.
10258 (Finternal_make_lisp_face, cache_face):
10259 Check for size calculation overflow.
10260 (cache_face): Treat size calculation overflows as if they were
10261 memory exhaustion (the usual treatment), rather than aborting.
10263 * xfns.c (x_encode_text, x_set_name_internal)
10264 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10265 sizes, since they can exceed INT_MAX in size. Check for size
10266 calculation overflow.
10268 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
10269 (xg_select): Check for size calculation overflow.
10270 Don't update size until alloc done.
10272 * xrdb.c (get_environ_db): Don't assume path length fits in int,
10273 as sprintf is limited to int lengths.
10275 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10276 (X_LONG_MIN): New macros.
10277 Use them to make the following changes clearer.
10278 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10279 This change doesn't affect the value now, but it may help remind
10280 future maintainers not to raise the value too much later.
10281 (SELECTION_QUANTUM): Remove, replacing with ...
10282 (selection_quantum): ... new function, which avoids overflow.
10284 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10285 assumption that selection length fits in 'int'.
10286 (x_reply_selection_request, x_handle_selection_request)
10287 (x_get_window_property, receive_incremental_selection)
10288 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
10289 (lisp_data_to_selection_data, clean_local_selection_data):

10291 (x_reply_selection_request, x_get_window_property)
10292 (receive_incremental_selection, x_property_data_to_lisp):
10293 Redo calculations to avoid overflow.
10294 (x_reply_selection_request): When sending hint, ceiling it at
10295 X_LONG_MAX rather than relying on wraparound overflow to send
10297 (x_get_window_property, receive_incremental_selection)
10298 (lisp_data_to_selection_data, x_property_data_to_lisp):
10299 Check for size-calculation overflow.
10300 (x_get_window_property, receive_incremental_selection)
10301 (lisp_data_to_selection_data, Fx_register_dnd_atom):
10302 Don't store size until memory allocation succeeds.
10303 (x_get_window_property): Plug memory leak on memory exhaustion.
10304 Don't double-block input; malloc is safe here. Don't assume 2**34
10305 - 4 fits in unsigned long. Add an xassert to check
10306 XGetWindowProperty overflow. Be more careful about overflow
10307 calculations, and distinguish size from memory overflow better.
10308 (receive_incremental_selection): When tracing, don't assume
10309 unsigned int is less than INT_MAX.
10310 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
10311 harmful) conversions of unsigned short to int.
10312 (lisp_data_to_selection_data): Don't assume that integers
10313 in the range -65535 through -1 fit in an X unsigned short.
10314 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10315 result parameters unless successful. Rely on cons_to_unsigned
10316 to report problems with elements; the old code wasn't right anyway.
10317 (x_check_property_data): Check for int overflow; we cannot use
10318 a wider type due to X limits.
10319 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
10321 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

10350 * image.c (xpm_get_color_table_h):
10351 * lisp.h (hash_lookup, hash_put):
10352 * minibuf.c (Ftest_completion):
10353 Use ptrdiff_t for hash table indexes, not int (which is too
10354 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10355 32-bit --with-wide-int hosts).
10357 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10358 Add a FIXME comment about memory leaks.
10359 (syms_of_charset): Don't assume xmalloc returns.
10361 Don't assume that stated character widths fit in int.
10362 * character.c (Fchar_width, c_string_width, lisp_string_width):
10363 * character.h (CHAR_WIDTH):
10364 * indent.c (MULTIBYTE_BYTES_WIDTH):
10365 Use sanitize_char_width to avoid undefined and/or bad behavior
10366 with outlandish widths.
10367 * character.h (sanitize_tab_width): Rename from sanitize_width,
10368 now that we have two such functions. All uses changed.
10369 (sanitize_char_width): New inline function.
10371 Don't assume that tab-width fits in int.
10372 * character.h (sanitize_width): New inline function.
10373 (SANE_TAB_WIDTH): New macro.
10374 (ASCII_CHAR_WIDTH): Use it.
10375 * indent.c (sane_tab_width): Remove. All uses replaced by

10379 * fileio.c: Integer overflow issues with file modes.
10380 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
10382 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
10383 Remove unreachable code.
10384 (read_hex, load_charset_map_from_file): Check for integer overflow.
10386 * xterm.c: Don't go over XClientMessageEvent limit.
10387 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10388 (x_send_scroll_bar_event): Likewise. Check that the size does not
10389 exceed limits imposed by XClientMessageEvent, as well as the usual
10390 ptrdiff_t and size_t limits.
10392 * keyboard.c: Overflow, signedness and related fixes.
10393 (make_lispy_movement): Use same integer type in forward decl
10394 that is used in the definition.
10395 (read_key_sequence, keyremap_step):
10396 Change bufsize argument back to int, undoing my 2011-03-30 change.
10397 We prefer signed types, and int is wide enough here.
10398 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10399 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10400 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10401 length, not size_t. Use ptrdiff_t for index, not int.
10402 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10403 possibility of integer overflow.
10405 Overflow, signedness and related fixes for images.
10407 * dispextern.h (struct it.stack[0].u.image.image_id)

10415 * xdisp.c (calc_pixel_width_or_height):
10416 * xfns.c (image_cache_refcount):
10417 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
10418 on typical 64-bit hosts.

10424 when the callers expect that.
10425 (image_ascent): Redo ascent calculation to avoid int overflow.
10426 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
10427 (lookup_image): Remove unnecessary tests.
10428 (xbm_image_p): Locals are now of int, not EMACS_INT,
10429 since parse_image_check makes sure they fit into int.
10430 (png_load, gif_load, svg_load_image):
10431 Prefer int to unsigned where either will do.
10432 (tiff_handler): New function, combining the cores of the
10433 old tiff_error_handler and tiff_warning_handler.
10434 This function is rewritten to use vsnprintf and thereby avoid
10435 stack buffer overflows. It uses only the features of vsnprintf
10436 that are common to both POSIX and native Microsoft.
10437 (tiff_error_handler, tiff_warning_handler): Use it.
10438 (tiff_load, gif_load, imagemagick_load_image):
10439 Don't assume :index value fits in 'int'.
10440 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
10441 (imagemagick_load_image): Check that crop parameters fit into
10442 the integer types that MagickCropImage accepts. Don't assume
10443 Vimagemagick_render_type has a nonnegative value. Don't assume
10444 size_t fits in 'long'.
10445 (gs_load): Use printmax_t to print the widest integers possible.
10446 Check for integer overflow when computing image height and width.

10455 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
10456 the display spec is of the form `(space ...)'.
10457 (handle_display_spec): Return the value returned by
10458 handle_single_display_spec, not just 1 or zero.
10459 (handle_single_display_spec): If the display spec is of the form
10460 `(space ...)', and specifies display in the text area, return 2
10462 (try_cursor_movement): Check for the need to scroll more
10463 accurately, and prefer exact match for point under bidi.
10464 Don't advance `row' beyond the last row of the window.
10466 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
10467 into disp_prop; all users changed.
10469 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
10470 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
10471 for the text covered by the display property.

10481 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
10482 buffers, return left-to-right.
10483 (set_cursor_from_row): Consider candidate row a win if its glyph
10484 represents a newline and point is on that newline. Fixes cursor
10485 positioning on the newline at EOL of R2L text within L2R
10486 paragraph, and vice versa.
10487 (try_cursor_movement): Check continued rows, in addition to
10488 continuation rows. Fixes unwarranted scroll when point enters a
10489 continued line of R2L text within an L2R paragraph, or vice versa.
10490 (cursor_row_p): Consider the case of point being equal to
10491 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10492 from the end of a short line to the beginning of a continued line
10493 of R2L text within L2R paragraph.
10494 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
10495 composed characters.
10497 * bidi.c (bidi_check_type): Use xassert.

10510 2011-08-22 Kenichi Handa <handa@m17n.org>
10512 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
10513 extra slot even if the purpose is char-code-property-table.
10515 2011-08-23 Eli Zaretskii <eliz@gnu.org>
10517 * xdisp.c (redisplay_window): When computing centering_position,
10518 account for the height of the header line. (Bug#8874)
10520 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10521 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10522 candidate is selected by the mouse, and that candidate has a
10523 composed character under the mouse.
10525 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10526 coordinates reported by pos-visible-in-window-p for a composed
10527 character in column zero.
10529 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
10531 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
10533 2011-08-22 Eli Zaretskii <eliz@gnu.org>
10535 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
10536 consider it a hit if to_charpos is anywhere in the range of the
10537 composed buffer positions.
10539 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10541 * image.c (gif_load): Don't assume that each subimage has the same
10542 dimensions as the base image. Handle disposal method that is
10543 "undefined" by the gif spec (Bug#9335).
10545 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10547 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10550 2011-08-19 Eli Zaretskii <eliz@gnu.org>
10552 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
10553 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10554 from an Org mode buffer to a Speedbar frame.
10556 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10557 a composition, take its buffer position from IT->cmp_it.charpos.
10558 Fixes cursor positioning at the beginning of a line that begins
10559 with a composed character.
10561 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10563 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10564 character bidirectional type, use STRONG_L instead. Fixes crashes
10565 in a buffer produced by `describe-categories'.
10567 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10568 members before the level stack, so they would be saved and
10569 restored when copying iterator state. Fixes incorrect reordering
10570 around TABs covered by display properties.
10572 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10574 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10579 (internal_condition_case_2, internal_condition_case_n):
10580 Remove unnecessary aborts (Bug#9081).
10582 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10584 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10585 has no `load' handler, try opening the file locally. (Bug#9311)
10587 2011-08-16 Ken Brown <kbrown@cornell.edu>
10589 * gmalloc.c: Expand comment.
10591 2011-08-16 Eli Zaretskii <eliz@gnu.org>
10593 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
10594 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

10634 coordinates of the iterator when restoring from ppos_it.
10637 2011-08-14 Kenichi Handa <handa@m17n.org>
10639 * process.c (create_process): Call setup_process_coding_systems
10640 after the pid of the process is set to -1 (Bug#8162).
10642 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10644 * xdisp.c (move_it_in_display_line_to): Don't invoke
10645 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10646 ppos_it. Fixes vertical cursor motion when line beginning is
10647 covered by an image. (Bug#9296)
10649 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10651 * nsterm.h (ns_run_ascript): Declare.

10655 (ns_run_ascript): New function.
10656 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10657 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10658 the event loop. Get status from as_status (Bug#7276).
10660 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10661 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10662 the event loop (Bug#7276).
10664 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

10687 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10688 (Fnetwork_interface_list): Allocate in increments of bytes instead
10689 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10690 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10692 (struct ifflag_def): notrailers is smart on OSX.
10693 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10694 Get hardware address with getifaddrs if available.
10696 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10698 * xdisp.c (iterate_out_of_display_property): xassert that
10699 IT->position is set to within IT->object's boundaries. Break from
10700 the loop as soon as EOB is reached; avoids infloops in redisplay
10701 when IT->position is set up wrongly due to some bug.
10702 Set IT->current to match the bidi iterator unconditionally.
10703 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10704 entry. Force push_it to save on the stack the current
10705 buffer/string position, to be restored by pop_it. Fix flags in
10706 the iterator structure wrt the object coming from a display
10707 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10708 properties. (Bug#9284)
10710 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10712 * fontset.c (fontset_get_font_group): Add proper type checks.

10725 no-display-properties-and-no-overlays under bidi display.
10726 Set disp_pos in the bidi iterator to avoid searches for display
10727 properties and overlays.
10729 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10731 * editfns.c (Fset_time_zone_rule): Document relationship with the

10737 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10739 * composite.c (autocmp_chars): Don't reset point. That is done by
10740 restore_point_unwind (Bug#5984).
10742 2011-08-07 Juri Linkov <juri@jurta.org>
10744 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10745 to show the arg `TIME' instead of `TIMEVAL'.
10747 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10749 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10750 display property strides EOL and includes a newline, as in
10751 longlines-mode. (Bug#9254)
10752 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10753 word-wrap under bidirectional display. (Bug#9224)
10755 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10756 is non-zero, even if the data buffer is NULL. Fixes a crash in
10757 vertical-motion with longlines-mode. (Bug#9254)
10759 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10761 * bidi.c <bidi_cache_total_alloc>: Now static.
10762 (bidi_initialize): Initialize bidi_cache_total_alloc.
10764 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10767 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10768 amount allocated this far in `bidi_cache_total_alloc'.
10769 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10770 non-zero, only free the data buffer without restoring the cache
10771 contents. All callers changed.
10773 * dispextern.h (bidi_unshelve_cache): Update prototype.
10775 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10776 (move_it_in_display_line, move_it_to)
10777 (move_it_vertically_backward, move_it_by_lines): Replace the call
10778 to xfree to an equivalent call to bidi_unshelve_cache.
10779 (move_it_in_display_line_to): Fix logic of returning
10780 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
10782 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10784 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
10785 came from a string character with a `cursor' property. (Bug#9229)
10787 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10789 * Makefile.in (LIB_PTHREAD): New variable.
10790 (LIBES): Add LIB_PTHREAD (Bug#9216).
10792 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:

10799 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10801 * xterm.c (x_find_topmost_parent): New function.
10802 (x_set_frame_alpha): Find topmost parent window with
10803 x_find_topmost_parent and set the property there also (bug#9181).
10804 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
10806 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
10808 * callproc.c (Fcall_process): Avoid vfork clobbering
10809 the local vars buffer, coding_systems, current_dir.
10811 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
10813 * keymap.c (Fmake_composed_keymap): Move to subr.el.
10815 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
10817 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
10818 so that it is not optimized away.
10820 * xdisp.c (compute_display_string_pos): Remove unused local.
10822 2011-08-02 Eli Zaretskii <eliz@gnu.org>
10824 Fix slow cursor motion and scrolling in large buffers with
10825 selective display, like Org Mode buffers. (Bug#9218)
10827 * dispextern.h (struct bidi_it): New member disp_prop_p.
10829 * xdisp.c: Remove one-slot cache of display string positions.
10830 (compute_display_string_pos): Accept an additional argument
10831 DISP_PROP_P; callers changed. Scan at most 5K characters forward
10832 for a display string or property. If found, set DISP_PROP_P
10835 * bidi.c (bidi_fetch_char): Accept an additional argument
10836 DISP_PROP_P, and pass it to compute_display_string_pos.
10837 Only handle text covered by a display string if DISP_PROP_P is returned
10838 non-zero. All callers of bidi_fetch_char changed.
10840 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
10842 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
10844 2010-12-03 Don March <don@ohspite.net>
10846 * keymap.c (Fdefine_key): Fix non-prefix key error message when
10847 last character M-[char] is translated to ESC [char] (bug#7541).
10849 2011-08-02 Kenichi Handa <handa@m17n.org>
10851 * lisp.h (uniprop_table): Extern it.
10853 * chartab.c (uniprop_table): Make it non-static.
10855 2011-08-01 Eli Zaretskii <eliz@gnu.org>
10857 * xdisp.c (forward_to_next_line_start): Accept additional argument
10858 BIDI_IT_PREV, and store into it the state of the bidi iterator had
10860 (reseat_at_next_visible_line_start): Use the bidi iterator state
10861 returned by forward_to_next_line_start to restore the state of
10862 it->bidi_it after backing up to previous newline. (Bug#9212)
10864 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
10866 * regex.c (re_comp): Protoize.
10867 (re_exec): Fix return type.
10868 (regexec): Fix type of `ret'. (Bug#9203)
10870 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10872 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
10873 This is needed if max-image-size is a floating-point number.
10875 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10877 * print.c (print_object): Print empty symbol as ##.
10879 * lread.c (read1): Read ## as empty symbol.
10881 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10883 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
10884 setting frame foreground color (Bug#9175).
10885 (x_set_background_color): Likewise.
10887 * nsmenu.m (-setText): Size tooltip dimensions precisely to
10888 contents (Bug#9176).
10889 (EmacsTooltip -init): Remove bezels and add shadows to
10892 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
10893 or scroll bar (Bug#8470).
10895 * nsfont.m (nsfont_open): Remove assignment to voffset and
10896 unnecessary vars hshink, expand, hd, full_height, min_height.
10897 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
10899 * nsterm.h (nsfont_info): Remove voffset field.
10901 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10903 Implement strike-through and overline on NextStep (Bug#8863).
10905 * nsfont.m (nsfont_open): Use underline position provided by font,
10906 instead of hard-coded value of 2.
10907 (nsfont_draw): Call ns_draw_text_decoration instead.
10909 * nsterm.h: Add declaration for ns_draw_text_decoration.
10911 * nsterm.m (ns_draw_text_decoration): New function for drawing
10912 underline, overline, and strike-through.
10913 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
10914 ns_draw_text_decoration. Change treatment of cursor drawing to
10915 accommodate underlining, etc.
10917 2011-07-28 Eli Zaretskii <eliz@gnu.org>
10919 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
10922 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10924 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
10925 Without this fix, if a signal arrives just after memory fills up,
10926 'malloc' might be invoked reentrantly.
10928 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
10929 In other words, assume that every image size is allowed, on non-X
10930 hosts. This assumption is probably wrong, but it lets Emacs compile.
10932 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10934 * regex.c (re_iswctype): Convert return values to boolean.
10936 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
10938 * xdisp.c (compute_display_string_pos): Don't use cached display
10939 string position if the buffer had its restriction changed.
10942 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10944 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10946 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10948 Integer signedness and overflow and related fixes. (Bug#9079)
10950 * bidi.c: Integer size and overflow fixes.
10951 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
10952 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
10953 (bidi_cache_find_level_change, bidi_cache_ensure_space)
10954 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
10955 (bidi_find_other_level_edge):
10956 Use ptrdiff_t instead of EMACS_INT where either will do.
10957 This works better on 32-bit hosts configured --with-wide-int.
10958 (bidi_cache_ensure_space): Check for size-calculation overflow.
10959 Use % rather than repeated addition, for better worst-case speed.
10960 Don't set bidi_cache_size until after xrealloc returns, because it
10962 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
10963 (bidi_cache_ensure_space): Also check that the bidi cache size
10964 does not exceed that of the largest Lisp string or buffer. See Eli
10965 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
10967 * alloc.c (__malloc_size_t): Remove.
10968 All uses replaced by size_t. See Andreas Schwab's note
10969 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
10971 * image.c: Improve checking for integer overflow.
10972 (check_image_size): Assume that f is nonnull, since
10973 it is always nonnull in practice. This is one less thing to
10974 worry about when checking for integer overflow later.
10975 (x_check_image_size): New function, which checks for integer
10976 overflow issues inside X.
10977 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
10978 This removes the need for a memory_full check.
10979 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
10980 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
10981 (xbm_read_bitmap_data): Change locals back to 'int', since
10982 their values must fit in 'int'.
10983 (xpm_load_image, png_load, tiff_load):
10984 Invoke x_create_x_image_and_pixmap earlier,
10985 to avoid much needless work if the image is too large.
10986 (tiff_load): Treat overly large images as if
10987 x_create_x_image_and_pixmap failed, not as malloc failures.
10988 (gs_load): Use x_check_image_size.
10990 * gtkutil.c: Omit integer casts.
10991 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
10992 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
10994 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
10996 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
10997 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
10998 would wrongly return t on a 64-bit host.
11000 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11001 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11002 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11003 and therefore cause GCC to emit a bogus diagnostic in some cases.
11005 * image.c: Integer signedness and overflow and related fixes.
11006 This is not an exhaustive set of fixes, but it's time to
11007 record what I've got.
11008 (lookup_pixel_color, check_image_size): Remove redundant decls.
11009 (check_image_size): Don't assume that arbitrary EMACS_INT values
11010 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11011 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11012 (tiff_load, imagemagick_load_image):
11013 Check for overflow in size calculations.
11014 (x_create_x_image_and_pixmap): Remove unnecessary test for
11015 xmalloc returning NULL; that can't happen.
11016 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11017 (xpm_color_bucket): Use better integer hashing function.
11018 (xpm_cache_color): Don't possibly over-allocate memory.
11019 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11020 (gif_memory_source):
11021 Use ptrdiff_t, not int or size_t, to record sizes.
11022 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11023 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11024 either works, as we prefer signed integers.
11025 (tiff_read_from_memory, tiff_write_from_memory):
11026 Return tsize_t, not size_t, since that's what the TIFF API wants.
11027 (tiff_read_from_memory): Don't fail simply because the read would
11028 go past EOF; instead, return a short read.
11029 (tiff_load): Omit no-longer-needed casts.
11030 (Fimagemagick_types): Don't assume size fits into 'int'.
11032 Improve hashing quality when configured --with-wide-int.
11033 * fns.c (hash_string): New function, taken from sxhash_string.
11034 Do not discard information about ASCII character case; this
11035 discarding is no longer needed.
11036 (sxhash-string): Use it. Change sig to match it. Caller changed.
11037 * lisp.h: Declare it.
11038 * lread.c (hash_string): Remove, since we now use fns.c's version.
11039 The fns.c version returns a wider integer if --with-wide-int is
11040 specified, so this should help the quality of the hashing a bit.
11042 * emacs.c: Integer overflow minor fix.
11043 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11044 Define only if GNU_LINUX.
11045 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11047 * dispnew.c: Integer signedness and overflow fixes.
11048 Remove unnecessary forward decls, that were a maintenance hassle.
11049 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11051 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11052 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11053 (prepare_desired_row, line_draw_cost):
11054 Use int, not unsigned, where either works.
11055 (save_current_matrix, restore_current_matrix):
11056 Use ptrdiff_t, not size_t, where either works.
11057 (init_display): Check for overflow more accurately, and without
11058 relying on undefined behavior.
11060 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11061 Remove, replacing with the new symbols in lisp.h. All uses changed.
11062 * fileio.c (make_temp_name):
11063 * filelock.c (lock_file_1, lock_file):
11064 * xdisp.c (message_dolog):
11065 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11066 Use pMd etc. instead.
11067 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11068 replacing the pWIDE etc. symbols removed from editfns.c.
11070 * keyboard.h (num_input_events): Now uintmax_t.
11071 This is (very slightly) less likely to mess up due to wraparound.
11074 * buffer.c: Integer signedness fixes.
11075 (alloc_buffer_text, enlarge_buffer_text):
11076 Use ptrdiff_t rather than size_t when either will do, as we prefer
11079 * alloc.c: Integer signedness and overflow fixes.
11080 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11081 (__malloc_size_t): Default to size_t, not to int.
11082 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11083 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11084 Prefer ptrdiff_t to size_t when either would do, as we prefer
11086 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11087 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11088 Now const. Initialize with values that are in range even if char
11090 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11091 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11092 These functions do the right thing with sizes > 2**32.
11093 (check_depth): Now ptrdiff_t, not int.
11094 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11095 Adjust to new way of storing sizes. Check for size overflow bugs
11097 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11098 slightly wrong anyway, as it missed one instance of
11099 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11100 (refill_memory_reserve): Omit needless cast to size_t.
11101 (mark_object_loop_halt): Mark as externally visible.
11103 * xselect.c: Integer signedness and overflow fixes.
11104 (Fx_register_dnd_atom, x_handle_dnd_message):
11105 Use ptrdiff_t, not size_t, since we prefer signed.
11106 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11107 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11108 x_dnd_atoms_size and x_dnd_atoms_length.
11110 * doprnt.c: Prefer signed to unsigned when either works.
11112 * doprnt.c (doprnt):
11114 * xdisp.c (vmessage):
11115 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11116 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11117 prefer signed arithmetic to avoid comparison confusion.
11118 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11119 but is a bit tricky.
11121 Assume freestanding C89 headers, string.h, stdlib.h.
11122 * data.c, doprnt.c, floatfns.c, print.c:
11123 Include float.h unconditionally.
11124 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11125 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11126 * regex.c: Likewise for stddef.h, string.h.
11127 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11128 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11129 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11130 (STDC_HEADERS): Remove obsolete defines.
11131 * sysdep.c: Include limits.h unconditionally.
11133 Assume support for memcmp, memcpy, memmove, memset.
11134 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11135 * regex.c (memcmp, memcpy):
11136 Remove; we assume C89 now.
11138 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11139 (__malloc_safe_bcopy): Remove; no longer needed.
11141 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11142 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11143 well either way, and we prefer signed to unsigned.
11145 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11147 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11148 closes the connection while we're reading (bug#9182).
11150 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11152 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11153 are specified (Bug#9168).
11155 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11157 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11158 Found by GCC static checking and --with-wide-int on a 32-bit host.
11160 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11162 * xdisp.c (compute_display_string_pos): Fix logic of caching
11163 previous display string position. Initialize cached_prev_pos to
11164 -1. Fixes slow-down at the beginning of a buffer.
11166 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11168 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11169 for attrs[LFACE_FONTSET_INDEX].
11171 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11173 * xml.c (parse_region): Remove unused local
11174 that was recently introduced.
11176 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11178 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11179 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11181 * xdisp.c (move_it_in_display_line_to): Record the best matching
11182 position for TO_CHARPOS while scanning the line, and restore it on
11183 exit if none of the characters scanned was an exact match.
11184 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11185 when exact match is impossible due to invisible text, and the
11186 lines are truncated.
11188 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11190 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11193 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11195 Fix a significant slow-down of cursor motion with C-n, C-p,
11196 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11197 auto-repeat under bidi redisplay in fontified buffers.
11198 * xdisp.c (compute_stop_pos_backwards): New function.
11199 (next_element_from_buffer): Call compute_stop_pos_backwards to
11200 find a suitable prev_stop when we find ourselves before
11202 (reseat): Don't look for prev_stop, as that could mean a very long
11204 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11205 <cached_disp_overlay_modiff>: Cache for last found display string
11207 (compute_display_string_pos): Return the cached position if asked
11208 about the same buffer in the same area of character positions, and
11209 the buffer wasn't changed since the time the display string
11210 position was cached.
11212 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11214 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11215 is an integer, which is important for empty lines. (Bug#9149)
11217 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11219 * frame.c (Fmodify_frame_parameters): In tty case, update the
11220 default face if necessary (Bug#4238).
11222 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11224 * editfns.c (Fstring_to_char): No need to explain what a character
11225 is in the docstring (Bug#6576).
11227 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11229 * xml.c (parse_region): Make sure we always return a tree.
11231 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11233 * xml.c (parse_region): If a document contains only comments,
11236 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11238 * xml.c (make_dom): Return comments, too.
11240 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11243 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11244 and the surrounding thread.
11245 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11246 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11247 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11249 * s/openbsd.h (BROKEN_SIGIO): Define.
11250 * unexelf.c (unexec) [__OpenBSD__]:
11251 Don't update the .mdebug section of the Alpha COFF symbol table.
11253 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11255 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11258 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11260 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11261 This fixes some race conditions on the permissions of any newly
11264 * alloc.c (valid_pointer_p): Use pipe, not open.
11265 This fixes some permissions issues when debugging.
11267 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11268 If fchown fails to set both uid and gid, try to set just gid,
11269 as that is sometimes allowed. Adjust the file's mode to eliminate
11270 setuid or setgid bits that are inappropriate if fchown fails.
11272 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11274 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

11280 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11282 * lread.c (read_integer): Unread even EOF character.
11283 (read1): Likewise. Properly record start position of symbol.

11286 symbol character follows.
11288 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11290 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11291 This works around a problem with the previous change to Fcopy_file.
11292 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11293 and without this change, GCC might complain about discarding
11294 fchown's return value.
11296 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11298 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11300 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11302 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11304 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11306 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11307 it's used from the C level.
11309 * process.c: Use the same condition for POLL_FOR_INPUT in both
11310 keyboard.c and process.c (bug#1858).
11312 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11314 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11315 (Fgnutls_boot): Use it.
11317 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11319 * doc.c (Fsubstitute_command_keys): Revert last change.
11321 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11323 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11324 quotes the next character, and doesn't affect other longer
11325 sequences (bug#8935).
11327 * lread.c (syms_of_lread): Clarify that is isn't only
11328 `eval-buffer' and `eval-defun' that's affected by
11329 `lexical-binding' (bug#8460).

11333 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11334 bidi redisplay when a line includes both an image and is truncated.
11336 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11338 Fix minor problems found by static checking.
11339 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11340 (elsz): Now a signed constant, not a size_t var. We prefer signed
11341 types to unsigned, to avoid integer comparison confusion. Without
11342 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11343 "cannot optimize loop, the loop counter may overflow", a symptom
11345 * indent.c (Fvertical_motion): Mark locals as initialized.
11346 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11348 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11350 * search.c (Fre_search_backward): Mention `case-fold-search' in
11351 all the re_search_* functions (bug#8138).

11374 (display_string): If we need to ignore text properties of
11375 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11376 original value of -1 will not work with bidi.)
11377 (compute_display_string_pos): First arg is now struct
11378 `text_pos *'; all callers changed. Support display properties on
11380 (compute_display_string_end): Support display properties on Lisp
11382 (init_iterator, reseat_1, reseat_to_string): Initialize the
11383 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11384 when iterating on a string not from display properties).
11385 (compute_display_string_pos, compute_display_string_end):
11386 Fix calculation of the object to scan. Fixes an error when using
11388 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11389 base_level_stop; instead, set base_level_stop to BEGV.
11390 Fixes crashes in vertical-motion.
11391 (next_element_from_buffer): Improve commentary for when
11392 the iterator is before prev_stop.
11393 (init_iterator): Initialize bidi_p from the default value of
11394 bidi-display-reordering, not from buffer-local value. Use the
11395 buffer-local value only if initializing for buffer iteration.

11416 parts of next_element_from_buffer, next_element_from_string, and
11417 next_element_from_c_string.
11418 (tool_bar_lines_needed, redisplay_tool_bar)
11419 (display_menu_bar): Force left-to-right direction. Add a FIXME
11420 comment for making that be controlled by a user option.

11434 pushed the iterator stack, restore the internal state of the bidi
11435 iterator by calling bidi_pop_it same number of times.
11436 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11437 and we are bidi-iterating, don't decrement the iterator position;
11438 instead, set the first_elt flag in the bidi iterator, to produce
11440 (reseat_1): Remove redundant setting of string_from_display_prop_p.
11441 (push_display_prop): xassert that we are iterating a buffer.

11445 (push_display_prop): Set up the `unibyte' member of bidi_it.string
11446 correctly. Don't assume unibyte strings are not bidi-reordered.

11455 property. Fix a typo in popping stretch info. Add an assertion
11456 for verifying that the iterator position is in sync with the bidi
11458 (handle_single_display_spec, get_overlay_strings_1)

11548 (struct iterator_stack_entry): New members bidi_p,
11549 paragraph_embedding, and from_disp_prop_p.

11872 This isn't true in general, and it's particularly not true
11873 if Emacs is configured with --with-wide-int.
11874 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
11875 New macros, used in the buffer.c change.

11911 Random fixes. E.g., (random) never returned negative values.
11912 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
11913 subseconds part to the entropy, as that's a bit more random.
11914 Prefer signed to unsigned, since the signedness doesn't matter and
11915 in general we prefer signed. When given a limit, use a
11916 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
11917 latter isn't right if USE_2_TAGS_FOR_INTS.
11918 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
11919 not 0..VALMASK. Don't discard "excess" bits that random () returns.

11931 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
11932 This is more efficient than Ffile_directory_p and avoids a minor race.

11936 * buffer.c (Foverlay_put): Say what the return value is
11939 * fileio.c (barf_or_query_if_file_exists): Check first if the file

11943 error be more correct.
11945 * fns.c (Frequire): Remove the mention of the .gz files, since
11946 that's installation-specific, but keep the mention of
11947 `get-load-suffixes'.

11962 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
11963 Also (re)move comments that are misplaced or no longer relevant.

11992 * lread.c (syms_of_lread): Mention single symbols defined by

12064 * eval.c (struct backtrace): Simplify and port the data structure.
12065 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12066 signed bit field, as this assumption is not portable and it makes
12067 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12068 "char debug_on_exit : 1" as this is not portable either; instead,
12069 use the portable "unsigned int debug_on_exit : 1". Remove unused
12070 member evalargs. Remove obsolete comments about cc bombing out.
12072 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12154 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
12155 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
12158 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
12160 * process.c (wait_reading_process_output): Bypass select if
12161 waiting for a cell while ignoring keyboard input, and input is
12162 pending. Suggested by Jan Djärv (Bug#8869).
12164 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
12166 Use gnulib's dup2 module instead of rolling our own.
12167 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

12238 * print.c (printchar, strout): Check for string overflow.
12239 (PRINTPREPARE, printchar, strout):
12240 Don't set size unless allocation succeeds.
12242 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12243 for sizes. Check for string overflow more accurately.
12244 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
12246 * macros.c: Integer and buffer overflow fixes.
12247 * keyboard.h (struct keyboard.kbd_macro_bufsize):
12248 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

12252 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
12254 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
12256 * lread.c: Integer overflow fixes.
12257 (read_integer): Radix is now EMACS_INT, not int,
12258 to improve quality of diagnostics for out-of-range radices.
12259 Calculate buffer size correctly for out-of-range radices.
12260 (read1): Check for integer overflow in radices, and in
12261 read-circle numbers.
12262 (read_escape): Avoid int overflow.
12263 (Fload, openp, read_buffer_size, read1)
12264 (substitute_object_recurse, read_vector, read_list, map_obarray):

12280 2011-06-22 Leo Liu <sdl.web@gmail.com>
12282 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
12283 Move to minibuffer.el.
12285 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12287 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12288 The following patches are for when GLYPH_DEBUG && !XASSERT.
12289 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12290 * dispnew.c (flush_stdout):
12291 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12292 Mark as externally visible.
12293 * dispnew.c (check_window_matrix_pointers): Now static.
12294 * dispnew.c (window_to_frame_vpos):
12295 * xfns.c (unwind_create_frame):
12296 * xterm.c (x_check_font): Remove unused local.
12297 * scroll.c (CHECK_BOUNDS):
12298 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12299 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
12300 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
12301 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
12302 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12304 (debug_method_add): Use va_list and vsprintf rather than relying
12305 on undefined behavior with wrong number of arguments.
12306 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12307 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12308 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12309 since we're not interested in debugging glyphs with old libraries.
12310 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12311 GCC 4.6.0's static checking.
12313 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12315 Integer overflow and signedness fixes (Bug#8873).

12331 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12332 (.bitmaps_last, struct x_output.icon_bitmap):
12333 Use ptrdiff_t, not int, for bitmap indexes.
12334 (x_allocate_bitmap_record): Check for size overflow.
12335 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12337 Use ptrdiff_t, not int, for overlay counts.
12338 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12339 * editfns.c (overlays_around, get_pos_property):
12340 * textprop.c (get_char_property_and_overlay):
12341 * xdisp.c (next_overlay_change, note_mouse_highlight):
12342 * xfaces.c (face_at_buffer_position):
12343 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12344 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12345 (Fnext_overlay_change, Fprevious_overlay_change)
12346 (mouse_face_overlay_overlaps, Foverlays_in):
12347 Use ptrdiff_t, not int, for sizes.
12348 (overlays_at, overlays_in): Check for size-calculation overflow.
12350 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12352 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12353 (x_session_initialize): Do not assume string length fits in int.
12355 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12356 This is unlikely, but can occur if DPI is outlandish.
12358 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12359 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12361 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12362 * xrdb.c (magic_file_p, search_magic_path):
12363 Omit last arg SUFFIX; it was always 0. All callers changed.
12364 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12366 * xfont.c (xfont_match): Avoid need for strlen.
12368 * xfns.c: Don't assume strlen fits in int.

12371 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12372 not unsigned long, as we prefer signed integers. All callers changed.
12373 Detect integer overflow in repeat count.
12374 (message_dolog): Don't assume print length fits in 39 bytes.
12375 (display_mode_element): Don't assume strlen fits in int.
12377 * termcap.c: Don't assume sizes fit in int and never overflow.
12378 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12379 (gobble_line): Check for size-calculation overflow.
12381 * minibuf.c (Fread_buffer):
12382 * lread.c (intern, intern_c_string):

12387 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12389 * font.c: Don't assume string length fits in int.
12390 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12391 Use ptrdiff_t, not int.
12392 (font_intern_prop): Don't assume string length fits in int.
12393 Don't assume integer property fits in fixnum.
12394 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12396 * filelock.c: Fix some buffer overrun and integer overflow issues.
12397 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12398 Reformulate so as not to need the command string.
12399 Invoke gzip -cd rather than gunzip, as it's more portable.
12400 (lock_info_type, lock_file_1, lock_file):
12401 Don't assume pid_t and time_t fit in unsigned long.
12402 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12403 (current_lock_owner): Prefer signed type for sizes.
12404 Use memcpy, not strncpy, where memcpy is what is really wanted.
12405 Don't assume (via atoi) that time_t and pid_t fit in int.
12406 Check for time_t and/or pid_t out of range, e.g., via a network share.
12407 Don't alloca where an auto var works fine.
12409 * fileio.c: Fix some integer overflow issues.
12410 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12411 Don't assume string length fits in int.
12412 (directory_file_name): Don't assume string length fits in long.
12413 (make_temp_name): Don't assume pid fits in int, or that its print
12414 length is less than 20.
12416 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12418 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12420 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

12434 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12436 * lread.c (invalid_syntax): Omit length argument.
12437 All uses changed. This doesn't fix a bug, but it simplifies the
12438 code away from its former Hollerith-constant appearance, and it's
12439 one less 'int' to worry about when looking at integer-overflow issues.
12440 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12442 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12443 This didn't break anything, but it didn't help either.
12444 It's confusing to put a bogus integer in a place where the actual
12445 value does not matter.
12446 (LIST_END_P): Remove unused macro and its bogus comment.
12447 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12449 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12450 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12452 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12453 We prefer signed types, and the value cannot exceed the EMACS_INT
12454 range anyway (because otherwise the length would not be representable).
12455 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12456 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12457 This avoids a GCC warning when WIDE_EMACS_INT.
12459 * indent.c (sane_tab_width): New function.
12460 (current_column, scan_for_column, Findent_to, position_indentation)
12461 (compute_motion): Use it. This is just for clarity.
12462 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12464 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

12468 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12470 * editfns.c, insdel.c:
12471 Omit unnecessary forward decls, to simplify future changes.
12473 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12475 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12477 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12478 Use much-faster test for byte-length change.
12479 Don't assume string byte-length fits in 'int'.
12480 Check that character arg fits in 'int'.
12481 (mapcar1): Declare byte as byte, for clarity.
12483 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12485 * fns.c (concat): Catch string overflow earlier.
12486 Do not rely on integer wraparound.
12488 * dispextern.h (struct it.overlay_strings_charpos)
12489 (struct it.selective): Now EMACS_INT, not int.
12490 * xdisp.c (forward_to_next_line_start)
12491 (back_to_previous_visible_line_start)
12492 (reseat_at_next_visible_line_start, next_element_from_buffer):
12493 Don't arbitrarily truncate the value of 'selective' to int.
12495 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12497 * composite.c: Don't truncate sizes to 'int'.
12498 (composition_gstring_p, composition_reseat_it)
12499 (composition_adjust_point): Use EMACS_INT, not int.
12500 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12501 not EMACS_UINT, for indexes.
12503 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12505 * buffer.c: Include <verify.h>.
12506 (struct sortvec.priority, struct sortstr.priority):
12507 Now EMACS_INT, not int.
12508 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12509 (struct sortstr.size, record_overlay_string)
12510 (struct sortstrlist.size, struct sortlist.used):
12511 Don't truncate size to int.
12512 (record_overlay_string): Check for size-calculation overflow.
12513 (init_buffer_once): Check at compile-time, not run-time.
12515 2011-06-22 Jim Meyering <meyering@redhat.com>
12517 Don't leak an XBM-image-sized buffer
12518 * image.c (xbm_load): Free the image buffer after using it.
12520 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12523 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12524 that Sun C diagnosed.
12525 * fns.c (secure_hash): Fix pointer signedness issue.
12526 * intervals.c (static_offset_intervals): New function.
12527 (offset_intervals): Use it.
12529 2011-06-21 Leo Liu <sdl.web@gmail.com>
12532 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12535 * fns.c (secure_hash): Rename from crypto_hash_function and change
12536 the first arg to accept symbols.
12537 (Fsecure_hash): New primitive.
12538 (syms_of_fns): New symbols.
12540 2011-06-20 Deniz Dogan <deniz@dogan.se>
12542 * process.c (Fset_process_buffer): Clarify return value in
12545 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12547 * dispnew.c (add_window_display_history): Use BVAR.

12553 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12556 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12557 check till after the cache is created in init_frame_faces.
12559 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12561 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12563 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12565 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12566 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12567 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12569 Improve buffer-overflow checking (Bug#8873).
12570 * fileio.c (Finsert_file_contents):
12571 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12572 Remove the old (too-loose) buffer overflow checks.
12573 They weren't needed, since make_gap checks for buffer overflow.
12574 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12575 The old code merely checked for Emacs fixnum overflow, and relied
12576 on undefined (wraparound) behavior. The new code avoids undefined
12577 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12579 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12580 Tune. Don't use wider integers than needed. Don't use alloca.
12581 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12583 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12585 * insdel.c, lisp.h (buffer_overflow): New function.
12586 (insert_from_buffer_1, replace_range, replace_range_2):
12587 * insdel.c (make_gap_larger):
12588 * editfns.c (Finsert_char):
12589 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12591 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12593 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12595 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12597 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12598 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12600 * fileio.c: Don't assume EMACS_INT fits in off_t.
12601 (emacs_lseek): New static function.
12602 (Finsert_file_contents, Fwrite_region): Use it.
12603 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12605 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12607 * fns.c: Don't overflow int when computing a list length.
12608 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12609 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12610 truncation on 64-bit hosts. Check for QUIT every
12611 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12612 faster and is responsive enough.
12613 (Flength): Report an error instead of overflowing an integer.
12614 (Fsafe_length): Return a float if the value is not representable
12615 as a fixnum. This shouldn't happen except in contrived situations.
12616 (Fnthcdr, Fsort): Don't assume list length fits in int.
12617 (Fcopy_sequence): Don't assume vector length fits in int.
12619 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12620 (header_size, word_size): New constants.
12621 (allocate_vectorlike): Don't check size overflow here.
12622 (allocate_vector): Check it here instead, since this is the only
12623 caller of allocate_vectorlike that could cause overflow.
12624 Check that the new vector's length is representable as a fixnum.
12626 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12627 The previous code was bogus. For example, next_almost_prime (32)
12628 returned 39, which is undesirable as it is a multiple of 3; and
12629 next_almost_prime (24) returned 25, which is a multiple of 5 so
12630 why was the code bothering to check for multiples of 7?
12632 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12634 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12636 Variadic C functions now count arguments with ptrdiff_t.
12637 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12638 Back then I didn't know that the Emacs coding style prefers signed int.
12639 Also, in the meantime I found a few more instances where arguments
12640 were being counted with int, which may truncate counts on 64-bit
12641 machines, or EMACS_INT, which may be unnecessarily wide.
12642 * lisp.h (struct Lisp_Subr.function.aMANY)
12643 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12644 Arg counts are now ptrdiff_t, not size_t.
12645 All variadic functions and their callers changed accordingly.
12646 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12647 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12648 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12649 * callint.c (Fcall_interactively): Check arg count for overflow,
12650 to avoid potential buffer overrun. Use signed char, not 'int',
12651 for 'varies' array, so that we needn't bother to check its size
12652 calculation for overflow.
12653 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12654 * eval.c (apply_lambda):
12655 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12656 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12657 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12659 * callint.c (Fcall_interactively): Don't use index var as event count.
12661 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12662 * mem-limits.h (SIZE): Remove; no longer used.
12664 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12666 Remove unnecessary casts.
12667 * xterm.c (x_term_init):
12668 * xfns.c (x_set_border_pixel):
12669 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12670 These aren't needed now that we assume ANSI C.
12672 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12673 It's more likely to cause problems (due to unsigned overflow)
12676 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12678 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12680 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12682 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12684 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12686 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12688 GLYPH_CODE_FACE returns EMACS_INT, not int.
12689 * dispextern.h (merge_faces):
12690 * xfaces.c (merge_faces):
12691 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12692 Don't assume EMACS_INT fits in int.
12694 * character.h (CHAR_VALID_P): Remove unused parameter.
12695 * fontset.c, lisp.h, xdisp.c: All uses changed.
12697 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12699 * fns.c (concat): Minor tuning based on overflow analysis.
12700 This doesn't fix any bugs. Use int to hold character, instead
12701 of constantly refetching from Emacs object. Use XFASTINT, not
12702 XINT, for value known to be a character. Don't bother comparing
12703 a single byte to 0400, as it's always less.
12705 * floatfns.c (Fexpt):
12706 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12708 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12711 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12713 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12714 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12715 incorrectly succeed when S was a string, because 4294967386 was
12716 truncated before it was used.
12718 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12719 Otherwise, an out-of-range integer could cause undefined behavior
12722 * composite.c: Use int, not EMACS_INT, for characters.
12723 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12724 EMACS_INT, for values that are known to be in character range.
12725 This doesn't fix any bugs but is the usual style inside Emacs and
12726 may generate better code on 32-bit machines.
12728 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12729 This is for reasons similar to the recent CHAR_STRING fix.
12730 * charset.c (Fencode_char): Check that character arg is actually
12731 a character. Pass an int to ENCODE_CHAR.
12732 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12733 wider than 'int', as a compile-time check to prevent future regressions
12736 * character.c (char_string): Remove unnecessary casts.
12738 Make sure a 64-bit char is never passed to CHAR_STRING.
12739 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12740 by silently ignoring the top 32 bits, allowing some values
12741 that were far too large to be valid characters.
12742 * character.h: Include <verify.h>.
12743 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12744 arguments are no wider than unsigned, as a compile-time check
12745 to prevent future regressions in this area.
12747 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12748 (Fsubst_char_in_region):
12750 * xdisp.c (decode_mode_spec_coding):
12751 Adjust to CHAR_STRING's new requirement.
12752 * editfns.c (Finsert_char, Fsubst_char_in_region):
12753 * fns.c (concat): Check that character args are actually
12754 characters. Without this test, these functions did the wrong
12755 thing with wildly out-of-range values on 64-bit hosts.
12757 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12758 These casts should not be needed on 32-bit hosts, either.
12759 * keyboard.c (read_char):
12760 * lread.c (Fload): Remove casts to unsigned.
12762 * lisp.h (UNSIGNED_CMP): New macro.
12763 This fixes comparison bugs on 64-bit hosts.
12764 (ASCII_CHAR_P): Use it.
12765 * casefiddle.c (casify_object):
12766 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
12767 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
12768 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
12769 * dispextern.h (FACE_FROM_ID):
12770 * keyboard.c (read_char): Use UNSIGNED_CMP.
12772 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
12773 not to EMACS_INT, to avoid GCC warning.
12775 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
12777 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
12778 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
12779 isn't needed on 32-bit machines.
12781 * buffer.c (Fgenerate_new_buffer_name):
12782 Use EMACS_INT for count, not int.
12783 (advance_to_char_boundary): Return EMACS_INT, not int.
12785 * data.c (Qcompiled_function): Now static.
12787 * window.c (window_body_lines): Now static.
12789 * image.c (gif_load): Rename local to avoid shadowing.
12791 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
12792 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
12793 * alloc.c (make_save_value): Integer argument is now of type
12794 ptrdiff_t, not int.
12795 (mark_object): Use ptrdiff_t, not int.
12796 * lisp.h (pD): New macro.
12797 * print.c (print_object): Use it.
12799 * alloc.c: Use EMACS_INT, not int, to count objects.
12800 (total_conses, total_markers, total_symbols, total_vector_size)
12801 (total_free_conses, total_free_markers, total_free_symbols)
12802 (total_free_floats, total_floats, total_free_intervals)
12803 (total_intervals, total_strings, total_free_strings):
12804 Now EMACS_INT, not int. All uses changed.
12805 (Fgarbage_collect): Compute overall total using a double, so that
12806 integer overflow is less likely to be a problem. Check for overflow
12807 when converting back to an integer.
12808 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
12809 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
12810 These were 'int' variables that could overflow on 64-bit hosts;
12811 they were never used, so remove them instead of repairing them.
12812 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
12813 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
12814 Previously, this ceilinged at INT_MAX, but that doesn't work on
12816 (allocate_pseudovector): Don't use EMACS_INT when int would do.
12818 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
12819 (allocate_vectorlike): Check for ptrdiff_t overflow.
12820 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
12821 when a (possibly-narrower) signed value would do just as well.
12822 We prefer using signed arithmetic, to avoid comparison confusion.
12824 * alloc.c: Catch some string size overflows that we were missing.
12825 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
12826 for convenience in STRING_BYTES_MAX.
12827 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
12828 The definition here is exact; the one in lisp.h was approximate.
12829 (allocate_string_data): Check for string overflow. This catches
12830 some instances we weren't catching before. Also, it catches
12831 size_t overflow on (unusual) hosts where SIZE_MAX <= min
12832 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
12833 and ptrdiff_t and EMACS_INT are both 64 bits.
12835 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
12836 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
12837 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
12839 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
12841 * alloc.c (Fmake_string): Check for out-of-range init.
12843 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
12845 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
12847 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
12849 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
12850 xg_get_default_scrollbar_width.
12852 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
12853 (int_gtk_range_get_value): Move to the scroll bar part of the file.
12854 (style_changed_cb): Call update_theme_scrollbar_width and call
12855 x_set_scroll_bar_default_width and xg_frame_set_char_size for
12856 all frames (Bug#8505).
12857 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
12858 Call gtk_window_set_resizable if HAVE_GTK3.
12859 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
12860 and height if HAVE_GTK3 (Bug#8505).
12861 (scroll_bar_width_for_theme): New variable.
12862 (update_theme_scrollbar_width): New function.
12863 (xg_get_default_scrollbar_width): Move code to
12864 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
12865 (xg_initialize): Call update_theme_scrollbar_width.
12867 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
12869 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
12871 2011-06-12 Martin Rudalics <rudalics@gmx.at>
12873 * frame.c (make_frame): Call other_buffer_safely instead of
12876 * window.c (temp_output_buffer_show): Call display_buffer with
12877 second argument Vtemp_buffer_show_specifiers and reset latter
12878 immediately after the call.
12879 (Vtemp_buffer_show_specifiers): New variable.
12880 (auto_window_vscroll_p, next_screen_context_lines)
12881 (Vscroll_preserve_screen_position): Remove leading asterisks from
12884 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
12886 Fix minor problems found by GCC 4.6.0 static checking.
12887 * buffer.c (Qclone_number): Remove for now, as it's unused.
12888 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
12889 (record_buffer): Remove unused local.
12890 * frame.c (other_visible_frames, frame_buffer_list): Now static.
12891 (set_frame_buffer_list): Remove; unused.
12892 * frame.h (other_visible_frames): Remove decl.
12893 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
12894 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
12895 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
12897 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
12898 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
12899 Define only if HAVE_GPM.
12900 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
12901 (update_hints_inhibit): Remove; never set. All uses removed.
12902 * widgetprv.h (emacsFrameClassRec): Remove decl.
12903 * window.c (delete_deletable_window): Now returns void, since it
12904 wasn't returning anything.
12905 (compare_window_configurations): Remove unused locals.
12906 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
12907 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
12908 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
12909 the same widths as pointers. This follows up on the 2011-05-06 patch.
12910 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
12911 * xterm.h: Likewise.
12912 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
12914 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
12916 * makefile.w32-in: Update dependencies.
12917 (LISP_H): Add lib/intprops.h.
12919 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
12921 * image.c (gif_load): Add animation frame delay to the metadata.
12922 (syms_of_image): Use DEFSYM. New symbol `delay'.
12924 2011-06-11 Martin Rudalics <rudalics@gmx.at>
12926 * window.c (delete_deletable_window): Re-add.
12927 (Fset_window_configuration): Rewrite to handle dead buffers and
12928 consequently deletable windows.
12929 (window_tree, Fwindow_tree): Remove. Supply functionality in
12931 (compare_window_configurations): Simplify code.
12933 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
12935 * image.c (imagemagick_load_image): Fix type mismatch.
12936 (Fimagemagick_types): Likewise.
12938 * window.h (replace_buffer_in_windows): Declare.
12940 2011-06-11 Martin Rudalics <rudalics@gmx.at>
12942 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
12943 Qclone_number. Remove external declaration of Qdelete_window.
12944 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
12946 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
12947 Run Qbuffer_list_update_hook if allowed.
12948 (Fother_buffer): Rewrite doc-string. Major rewrite for new
12949 buffer list implementation.
12950 (other_buffer_safely): New function.
12951 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
12952 calls to replace_buffer_in_windows and
12953 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
12955 (record_buffer): Inhibit quitting and rewrite using quittable
12956 functions. Run Qbuffer_list_update_hook if allowed.
12957 (Frecord_buffer, Funrecord_buffer): New functions.
12958 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
12959 Move switch-to-buffer to window.el.
12960 (bury-buffer): Move to window.el.
12961 (Vbuffer_list_update_hook): New variable.
12963 * lisp.h (other_buffer_safely): Add prototype in buffer.c
12966 * window.h (resize_frame_windows): Move up in code.
12967 (Fwindow_frame): Remove EXFUN.
12968 (replace_buffer_in_all_windows): Remove prototype.
12969 (replace_buffer_in_windows_safely): Add prototype.
12971 * window.c: Declare Qdelete_window static again. Move down
12972 declaration of select_count.
12973 (Fnext_window, Fprevious_window): Rewrite doc-strings.
12974 (Fother_window): Move to window.el.
12975 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
12976 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
12977 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
12979 (replace_buffer_in_windows): Implement by calling
12980 Qreplace_buffer_in_windows.
12981 (replace_buffer_in_all_windows): Remove with some functionality
12982 moved into replace_buffer_in_windows_safely.
12983 (replace_buffer_in_windows_safely): New function.
12984 (select_window_norecord, select_frame_norecord): Move in front
12985 of run_window_configuration_change_hook. Remove now obsolete
12987 (Fset_window_buffer): Rewrite doc-string.
12988 Call Qrecord_window_buffer.
12989 (keys_of_window): Move binding for other-window to window.el.
12991 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
12993 * dispextern.h (struct image): Replace data member, whose int_val
12994 and ptr_val fields were not used by anything, with a single
12997 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
12998 (gif_clear_image, gif_load, imagemagick_load_image)

13442 last portion of handle_display_prop.
13443 (compute_display_string_pos): Accept additional argument
13444 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13445 value of a `display' property is a "replacing spec".
13446 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13447 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13448 the display property, but just return a value indicating whether
13449 the display property will replace the characters it covers.
13450 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13451 frame_window_p members of struct bidi_it.
13452 (compute_display_string_pos, compute_display_string_end):
13454 (push_it): Accept second argument POSITION, where pop_it should
13455 jump to continue iteration.
13456 (reseat_1): Initialize bidi_it.disp_pos.
13458 * keyboard.c (adjust_point_for_property): Adjust the call to
13459 display_prop_intangible_p to its new signature.
13461 * dispextern.h (struct bidi_it): New member frame_window_p.
13462 (bidi_init_it): Update prototypes.

13464 (compute_display_string_pos, compute_display_string_end):
13465 Declare prototypes.
13466 (struct bidi_it): New members nchars and disp_pos. ch_len is now
13469 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
13471 Malloc failure behavior now depends on size of allocation.
13472 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
13473 * lisp.h: Change signatures accordingly.
13474 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
13475 All callers changed. (Bug#8762)
13477 * gnutls.c: Use Emacs's memory allocators.
13478 Without this change, the gnutls library would invoke malloc etc.
13479 directly, which causes problems on non-SYNC_INPUT hosts, and which
13480 runs afoul of improving memory_full behavior. (Bug#8761)
13481 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13482 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13483 xfree instead of the default malloc, realloc, free.
13484 (Fgnutls_boot): No need to check for memory allocation failure,
13485 since xmalloc does that for us.
13487 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
13488 * category.c (hash_get_category_set):
13489 * ccl.c (ccl_driver):
13490 * charset.c (Fdefine_charset_internal):
13491 * charset.h (struct charset.hash_index):
13492 * composite.c (get_composition_id, gstring_lookup_cache)
13493 (composition_gstring_put_cache):
13494 * composite.h (struct composition.hash_index):
13495 * dispextern.h (struct image.hash):
13496 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
13497 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

13500 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
13501 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
13502 (Fsxhash, Fgethash, Fputhash, Fmaphash):
13503 * image.c (make_image, search_image_cache, lookup_image)
13504 (xpm_put_color_table_h):
13505 * lisp.h (struct Lisp_Hash_Table):
13506 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
13507 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
13508 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13509 * alloc.c (allocate_vectorlike):
13510 Check for overflow in vector size calculations.
13511 * ccl.c (ccl_driver):
13512 Check for overflow when converting EMACS_INT to int.
13513 * fns.c, image.c: Remove unnecessary static decls that would otherwise
13514 need to be updated by these changes.
13515 * fns.c (make_hash_table, maybe_resize_hash_table):
13516 Check for integer overflow with large hash tables.
13517 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13518 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13519 (SXHASH_REDUCE): New macro.
13520 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13521 Use it instead of discarding useful hash info with large hash values.
13522 (sxhash_float): New function.
13523 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13524 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13525 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13526 Rewrite to use FIXNUM_BITS, as this simplifies things.
13527 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13528 Adjust signatures to match updated version of code.
13529 (consing_since_gc): Now EMACS_INT, since a single hash table can
13530 use more than INT_MAX bytes.
13532 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
13534 Make it possible to build with GCC-4.6+ -O2 -flto.
13536 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
13538 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
13540 * minibuf.c (get_minibuffer, read_minibuf_unwind):
13541 Call minibuffer-inactive-mode.
13543 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
13545 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
13546 Update dependencies.
13548 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13550 * data.c (init_data): Remove code for UTS, this system is not
13553 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13555 Don't force ./temacs to start in terminal mode.
13557 * frame.c (make_initial_frame): Initialize faces in all cases, not
13558 only when CANNOT_DUMP is defined.
13559 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
13561 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13563 * dispnew.c (add_window_display_history): Use const for the string
13564 pointer. Remove declaration, not needed.
13566 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13568 Use 'inline', not 'INLINE'.
13569 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
13570 * alloc.c, fontset.c (INLINE): Remove.
13571 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
13572 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
13573 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
13574 * gmalloc.c (register_heapinfo): Use inline unconditionally.
13575 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
13577 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13579 Make it possible to run ./temacs.
13581 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13582 syms_of_callproc does the same thing. Remove test for
13583 "initialized", do it in the caller.
13584 * emacs.c (main): Avoid calling set_initial_environment when dumping.
13586 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
13588 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
13589 (read_minibuf): Use get_minibuffer.
13590 (syms_of_minibuf): Use DEFSYM.
13591 (Qmetadata): New var.
13592 * data.c (Qbuffer): Don't make it static.
13593 (syms_of_data): Use DEFSYM.
13595 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13597 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
13598 (CCL_CODE_MIN): New macro.
13600 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
13602 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
13604 * eval.c (Qdebug): Now static.
13605 * lisp.h (Qdebug): Remove decl. This reverts a part of the
13606 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
13607 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
13609 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13611 * image.c: Various fixes to ImageMagick code comments.
13612 (Fimagemagick_types): Doc fix.
13614 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13616 Minor fixes prompted by GCC 4.6.0 warnings.
13618 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13620 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13621 (x_clipboard_manager_save_all): Move extern decl to ...
13622 * xterm.h: ... here, so that it can be checked for consistency.
13624 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13626 * xselect.c (x_clipboard_manager_save_frame)
13627 (x_clipboard_manager_save_all): New functions.
13628 (Fx_clipboard_manager_save): Lisp function deleted.
13630 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13631 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13633 * xterm.h: Update prototype.
13635 2011-05-28 William Xu <william.xwl@gmail.com>
13637 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13638 exiting (Bug#8239).
13640 2011-05-28 Jim Meyering <meyering@redhat.com>
13642 Avoid a sign-extension bug in crypto_hash_function.
13643 * fns.c (to_uchar): Define.
13644 (crypto_hash_function): Use it to convert some newly-signed
13645 variables to unsigned, to avoid sign-extension bugs. For example,
13646 without this change, (md5 "truc") would evaluate to
13647 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13648 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13649 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13651 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13653 Integer overflow fixes.
13655 * dbusbind.c: Serial number integer overflow fixes.
13656 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13657 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13658 to hold a serial number that is too large for a fixnum.
13659 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13660 Check for serial numbers out of range. Decode any serial number
13661 that was so large that it became a float. (Bug#8722)
13663 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13664 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13665 Use XFASTINT rather than XUINT when numbers are nonnegative.
13666 (xd_append_arg, Fdbus_method_return_internal):
13667 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13668 arguments, check that Lisp number is nonnegative, rather than
13669 silently wrapping negative numbers around. (Bug#8722)
13670 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13673 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13675 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13677 ccl: Add integer overflow checks.
13678 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13679 (IN_INT_RANGE): New macros.
13680 (ccl_driver): Use them to check for integer overflow when
13681 decoding a CCL program. Many of the new checks are whether XINT (x)
13682 fits in int; it doesn't always, on 64-bit hosts. The new version
13683 doesn't catch all possible integer overflows, but it's an
13684 improvement. (Bug#8719)
13686 * alloc.c (make_event_array): Use XINT, not XUINT.
13687 There's no need for unsigned here.
13689 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13690 This follows up to the 2011-05-06 change that substituted uintptr_t
13691 for EMACS_INT. This case wasn't caught back then.
13693 Rework Fformat to avoid integer overflow issues.
13694 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13695 now (part of C89). Include <verify.h>.
13696 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13697 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13698 (Fformat): Avoid the prepass trying to compute sizes; it was only
13699 approximate and thus did not catch overflow reliably. Instead, walk
13700 through the format just once, formatting and computing sizes as we go,
13701 checking for integer overflow at every step, and allocating a larger
13702 buffer as needed. Keep track separately whether the format is
13703 multibyte. Keep only the most-recently calculated precision, rather
13704 than them all. Record whether each argument has been converted to
13705 string. Use EMACS_INT, not int, for byte and char and arg counts.
13706 Support field widths and precisions larger than INT_MAX. Avoid
13707 sprintf's undefined behavior with conversion specifications such as %#d
13708 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13709 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13710 formatting out-of-range floating point numbers with int
13711 formats. (Bug#8668)
13713 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13715 * data.c: Avoid integer truncation in expressions involving floats.
13716 * data.c: Include <intprops.h>.
13717 (arith_driver): When there's an integer overflow in an expression
13718 involving floating point, convert the integers to floating point
13719 so that the resulting value does not suffer from catastrophic
13720 integer truncation. For example, on a 64-bit host (* 4
13721 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13722 Do not rely on undefined behavior after integer overflow.
13724 merge count_size_as_multibyte, parse_str_to_multibyte
13725 * character.c, character.h (count_size_as_multibyte):
13726 Rename from parse_str_to_multibyte; all uses changed.
13727 Check for integer overflow.
13728 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13729 since it's now a duplicate of the other. This is more of
13730 a character than a buffer op, so better that it's in character.c.
13731 * fns.c, print.c: Adjust to above changes.
13733 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13735 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13737 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13739 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13740 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13741 (x_clipboard_manager_save): Now static.
13742 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13744 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13745 (crypto_hash_function): Now static.
13746 Fix pointer signedness problems. Avoid unnecessary initializations.
13748 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13750 * termhooks.h (Vselection_alist): Make it terminal-local.
13752 * terminal.c (create_terminal): Initialize it.
13754 * xselect.c: Support for clipboard managers.
13755 (Vselection_alist): Move to termhooks.h as terminal-local var.
13756 (LOCAL_SELECTION): New macro.
13757 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13758 (symbol_to_x_atom): Remove gratuitous arg.
13759 (x_handle_selection_request, lisp_data_to_selection_data)
13760 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13761 (x_own_selection, x_get_local_selection, x_convert_selection):
13762 New arg, specifying work frame. Use terminal-local Vselection_alist.
13763 (some_frame_on_display): Delete unused function.
13764 (Fx_own_selection_internal, Fx_get_selection_internal)
13765 (Fx_disown_selection_internal, Fx_selection_owner_p)
13766 (Fx_selection_exists_p): New optional frame arg.
13767 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13768 (x_handle_selection_clear): Don't treat other terminals with the
13769 same keyboard specially. Use the terminal-local Vselection_alist.
13770 (x_clear_frame_selections): Use Frun_hook_with_args.
13772 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13774 * xterm.h: Add support for those atoms.
13776 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13778 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13779 (converted_selections, conversion_fail_tag): New global variables.
13780 (x_selection_request_lisp_error): Free the above.
13781 (x_get_local_selection): Remove unnecessary code.
13782 (x_reply_selection_request): Args changed; handle arbitrary array
13783 of converted selections stored in converted_selections.
13784 Separate the XChangeProperty and SelectionNotify steps.
13785 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
13786 (x_convert_selection): New function.
13787 (x_handle_selection_event): Simplify.
13788 (x_get_foreign_selection): Don't ignore incoming requests while
13789 waiting for an answer; this will fail when we implement
13790 SAVE_TARGETS, and seems unnecessary anyway.
13791 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
13792 (Vx_sent_selection_functions): Doc fix.
13794 2011-05-26 Leo Liu <sdl.web@gmail.com>
13796 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
13798 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13800 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
13802 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
13803 for fringe update if it has periodic bitmap.
13804 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
13805 and fringe_bitmap_periodic_p.
13807 * fringe.c (get_fringe_bitmap_data): New function.
13808 (draw_fringe_bitmap_1, update_window_fringes): Use it.
13809 (update_window_fringes): Record periodicity of fringe bitmap in glyph
13810 row. Mark glyph row for fringe update if periodicity changed.
13812 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
13813 for fringe update unless it has periodic bitmap.
13815 2011-05-25 Kenichi Handa <handa@m17n.org>
13817 * xdisp.c (get_next_display_element): Set correct it->face_id for
13818 a static composition.

13831 * gnutls.c: Remove unused macros.
13832 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
13833 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
13834 Remove macros that are defined and never used.
13835 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
13837 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13839 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
13840 (Fx_get_selection_internal): Minor cleanup.
13841 (Fx_own_selection_internal): Rename arguments for consistency with
13844 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

13866 report_file_error introduced by the change from 2011-05-07.
13868 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
13870 * systime.h (Time): Define only if emacs is defined.
13871 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
13872 where the include path doesn't have X11/X.h by default. See
13873 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
13875 2011-05-20 Kenichi Handa <handa@m17n.org>
13877 * composite.c (find_automatic_composition): Fix previous change.
13879 2011-05-20 Glenn Morris <rgm@gnu.org>
13881 * lisp.mk: New file, split from Makefile.in.
13882 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
13883 (shortlisp): Remove.
13884 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
13886 2011-05-19 Glenn Morris <rgm@gnu.org>
13888 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
13889 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
13890 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
13891 (lisp): Set the order to that of loadup.el.
13892 (shortlisp): Make it a copy of $lisp.
13893 (SOME_MACHINE_LISP): Remove.
13894 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
13895 Use just $shortlisp, not $SOME_MACHINE_LISP too.
13897 2011-05-18 Kenichi Handa <handa@m17n.org>
13899 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
13900 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
13901 (find_automatic_composition): Mostly rewrite for efficiency.
13903 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
13905 * makefile.w32-in: Update dependencies.
13907 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
13909 * menu.c: Include limits.h (fixes the MS-Windows build broken by
13910 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
13912 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
13914 Fix some integer overflow issues, such as string length overflow.
13916 * insdel.c (count_size_as_multibyte): Check for string overflow.
13918 * character.c (lisp_string_width): Check for string overflow.
13919 Use EMACS_INT, not int, for string indexes and lengths; in
13920 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
13921 the resulting string length overflows an EMACS_INT; instead,
13922 report a string overflow if no precision given. When checking for
13923 precision exhaustion, use a check that cannot possibly have
13924 integer overflow. (Bug#8675)
13925 * character.h (lisp_string_width): Adjust to new signature.
13927 * alloc.c (string_overflow): New function.
13928 (Fmake_string): Use it. This doesn't change behavior, but saves
13929 a few bytes and will simplify future changes.
13930 * character.c (string_escape_byte8): Likewise.
13931 * lisp.h (string_overflow): New decl.
13933 Fixups, following up to the user-interface timestamp change.
13934 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
13935 for UI timestamps, instead of unsigned long.
13936 * msdos.c (mouse_get_pos): Likewise.
13937 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
13938 * w32gui.h (Time): Define by including "systime.h" rather than by
13939 declaring it ourselves. (Bug#8664)
13941 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
13942 * image.c (clear_image_cache): Likewise.
13944 * term.c (term_mouse_position): Don't assume time_t wraparound.
13946 Be more systematic about user-interface timestamps.
13947 Before, the code sometimes used 'Time', sometimes 'unsigned long',
13948 and sometimes 'EMACS_UINT', to represent these timestamps.
13949 This change causes it to use 'Time' uniformly, as that's what X uses.
13950 This makes the code easier to follow, and makes it easier to catch
13951 integer overflow bugs such as Bug#8664.
13952 * frame.c (Fmouse_position, Fmouse_pixel_position):
13953 Use Time, not unsigned long, for user-interface timestamps.
13954 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
13955 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
13956 * keyboard.h (last_event_timestamp): Likewise.
13957 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
13958 * menu.h (xmenu_show): Likewise.
13959 * term.c (term_mouse_position): Likewise.
13960 * termhooks.h (struct input_event.timestamp): Likewise.
13961 (struct terminal.mouse_position_hook): Likewise.
13962 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
13963 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
13964 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
13965 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
13966 what it was before.
13967 * menu.h, termhooks.h: Include "systime.h", for Time.
13969 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
13970 Don't assume that the difference between two unsigned long values
13971 can fit into an integer. At this point, we know button_down_time
13972 <= event->timestamp, so the difference must be nonnegative, so
13973 there's no need to cast the result if double-click-time is
13974 nonnegative, as it should be; check that it's nonnegative, just in
13975 case. This bug is triggered when events are more than 2**31 ms
13976 apart (about 25 days). (Bug#8664)
13978 * xselect.c (last_event_timestamp): Remove duplicate decl.
13979 (x_own_selection): Remove needless cast to unsigned long.
13981 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
13982 that always fit in int. Use a sentinel instead of a counter, to
13983 avoid a temp and to allay GCC's concerns about possible int overflow.
13984 * frame.h (struct frame): Use int for menu_bar_items_used
13985 instead of EMACS_INT, since it always fits in int.
13987 * menu.c (grow_menu_items): Check for int overflow.
13989 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
13991 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
13992 Before, the code was not consistent. These values cannot exceed
13993 2**31 - 1 so there's no need to make them unsigned.
13994 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
13995 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
13996 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
13998 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14000 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14001 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14002 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14003 presumably because the widths might not match.
14005 * window.c (size_window): Avoid needless test at loop start.
14007 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14009 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14011 2011-05-12 Drew Adams <drew.adams@oracle.com>
14013 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14015 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14017 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14018 `width' to `bar_area_x' and `bar_area_width', respectively.
14019 (x_scroll_run): Take account of fringe background extension.
14021 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14022 Rename local vars `left' and `width' to `bar_area_x' and
14023 `bar_area_width', respectively.
14024 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14025 background extension.
14027 2011-05-10 Jim Meyering <meyering@redhat.com>
14029 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14031 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14033 * image.c (Finit_image_library): Return t for built-in image types,
14034 like pbm and xbm. (Bug#8640)
14036 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14038 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14040 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14042 * w32console.c (Fset_screen_color): Doc fix.
14043 (Fget_screen_color): New function.
14044 (syms_of_ntterm): Defsubr it.
14046 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14047 unlink the temporary file if Fcall_process didn't create it in the
14049 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14050 child process will be redirected to a file specified with `:file'.
14051 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14052 cue to call_process_cleanup not to close that handle.
14054 2011-05-07 Ben Key <bkey76@gmail.com>
14056 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14057 one of two shell specific rules, either bootstrap-temacs-CMD or
14058 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14059 to the previous implementation of the bootstrap-temacs rule.
14060 The bootstrap-temacs-CMD rule is similar to the previous
14061 implementation of the bootstrap-temacs rule except that it
14062 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14065 These changes, along with some changes to nt/configure.bat,
14066 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14067 earlier fix to add support for --cflags and --ldflags options
14068 that include quotes so that it works whether make uses cmd or
14071 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14073 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14074 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14076 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14077 a string. Handle both cases.
14078 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14079 (Fdbus_register_method): Use Qinvalid_function.
14081 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14083 * makefile.w32-in: Update dependencies.
14084 (LISP_H): Add inttypes.h and stdin.h.
14085 (PROCESS_H): Add unistd.h.
14087 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14089 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14090 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14092 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14094 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14096 * term.c (vfatal): Remove stray call to va_end.
14097 It's not needed and the C Standard doesn't allow it here anyway.
14099 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14100 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14102 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14105 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14107 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14109 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14111 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14113 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14115 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14116 * charset.c (Fdefine_charset_internal): Don't initialize
14117 charset.code_space[15]. The value was garbage, on hosts with
14118 32-bit int (Bug#8600).
14120 * lread.c (read_integer): Be more consistent with string-to-number.
14121 Use string_to_number to do the actual conversion; this avoids
14122 rounding errors and fixes some other screwups. Without this fix,
14123 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14124 (digit_to_number): Move earlier, for benefit of read_integer.
14125 Return -1 if the digit is out of range for the base, -2 if it is
14126 not a digit in any supported base. (Bug#8602)
14128 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14130 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14131 to match comment at start of function. This also removes a
14132 GCC warning about overflow in a 32+64-bit port.
14134 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14136 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14137 Reported by Stefan Monnier in
14138 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14139 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14140 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14142 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14143 (EMACS_UINTPTR): Likewise, with uintptr_t.
14145 * lisp.h: Prefer 64-bit EMACS_INT if available.
14146 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14147 on 32-bit hosts that have 64-bit int, so that they can access
14149 However, temporarily disable this change unless the temporary
14150 symbol WIDE_EMACS_INT is defined.
14152 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14154 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14155 This removes an assumption that EMACS_INT and long are the same
14156 width as pointers. The assumption is true for Emacs porting targets
14157 now, but we want to make other targets possible.
14158 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14159 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14160 In the rest of the code, change types of integers that hold casted
14161 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14162 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14163 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14164 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14165 No need to cast type when ORing.
14166 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14167 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14168 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14169 assume EMACS_INT is the same width as char *.
14170 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14171 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14172 Remove no-longer-needed casts.
14173 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14174 (xg_tool_bar_help_callback, xg_make_tool_item):
14175 Use EMACS_INTPTR to hold an integer
14176 that will be cast to void *; this can avoid a GCC warning
14177 if EMACS_INT is not the same width as void *.
14178 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14179 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14180 (current_message_1, set_message_1):
14181 Use a local to convert to proper width without a cast.
14182 * xmenu.c (dialog_selection_callback): Likewise.
14184 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14185 Also, don't assume VALBITS / RAND_BITS is less than 5,
14186 and don't rely on undefined behavior when shifting a 1 left into
14188 * lisp.h (get_random): Change signature to match.
14190 * lread.c (hash_string): Use size_t, not int, for hash computation.
14191 Normally we prefer signed values; but hashing is special, because
14192 it's better to use unsigned division on hash table sizes so that
14193 the remainder is nonnegative. Also, size_t is the natural width
14194 for hashing into memory. The previous code used 'int', which doesn't
14195 retain enough info to hash well into very large tables.
14196 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14198 * dbusbind.c: Don't possibly lose pointer info when converting.
14199 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14200 Use XPNTR rather than XHASH, so that the high-order bits of
14201 the pointer aren't lost when converting through void *.
14203 * eval.c (Fautoload): Don't double-shift a pointer.
14205 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14207 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14209 * gnutls.c (DEF_GNUTLS_FN):
14210 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14212 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14214 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14217 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14219 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14220 New version that can reserve upto 2GB of heap space.
14222 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14224 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14226 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14228 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14229 `gnutls_certificate_set_x509_key_file'.
14231 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14233 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14234 Update dependencies.
14236 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14238 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14239 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14240 Remove unused parameter `fildes'.
14241 * process.c (read_process_output, send_process): Don't pass it.
14243 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14245 Fix previous change: the library cache is defined in w32.c.
14246 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14247 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14249 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14251 Implement dynamic loading of GnuTLS on Windows.
14253 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14254 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14255 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14258 * gnutls.c (Qgnutls_dll): Define.
14259 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14260 (gnutls_*): Declare function pointers.
14261 (init_gnutls_functions): New function to initialize function pointers.
14262 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
14263 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
14264 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14265 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14266 (emacs_gnutls_write, emacs_gnutls_read)
14267 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14268 (Fgnutls_available_p): New function.
14269 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14270 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14271 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14273 * image.c: Include w32.h.
14274 (Vimage_type_cache): Delete.
14275 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
14276 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
14277 (w32_delayed_load): Move to w32.c.
14279 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14281 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14282 (w32_delayed_load): Move from image.c. When loading a library, record
14283 its filename in the :loaded-from property of the library id.
14284 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14285 Initialize and staticpro them.
14286 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14288 * process.c: Include lisp.h before w32.h, not after.
14289 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14290 instead of gnutls_record_check_pending.
14292 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14294 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14296 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14297 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14300 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14302 * xterm.c (x_set_frame_alpha): Do not set property on anything

14342 rather than `XVECTOR (FOO)->size'.
14344 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14345 inttypes.h, as a gnulib replacement is used if it not available in
14348 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14350 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

14358 space for up to 2 characters produced in a loop.
14359 (decode_coding_iso_2022): Abort if there isn't enough place in
14360 charbuf for the composition carryover bytes.
14362 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14364 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
14365 aborting when %lld or %lll format is passed.
14366 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14367 %llo or %llx format is passed. (Bug#8545)
14369 * window.c (window_scroll_line_based): Use a marker instead of
14370 simple variables to record original value of point. (Bug#7952)
14372 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14373 produced by %s or %c overflows available buffer space. (Bug#8545)
14375 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14377 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14378 (SIZE_MAX): Move defn after all includes, as they might #define it.
14380 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14382 * w32.c (init_environment): Warn about defaulting HOME to C:\.
14384 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14386 * keyboard.c (Qdelayed_warnings_hook): Define.
14387 (command_loop_1): Run `delayed-warnings-hook'
14388 if Vdelayed_warnings_list is non-nil.
14389 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
14390 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
14392 2011-04-28 Eli Zaretskii <eliz@gnu.org>
14394 * doprnt.c (doprnt): Don't return value smaller than the buffer
14395 size if the message was truncated. (Bug#8545).
14397 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14399 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
14400 (Fx_window_property): #if-0 the whole functions, not just the bodies.
14402 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14404 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14406 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14408 * makefile.w32-in: Update dependencies.
14410 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14412 Improve `doprnt' and its usage. (Bug#8545)
14413 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14414 `format_end'. Remove support for %l as a conversion specifier.
14415 Don't use xrealloc. Improve diagnostics when the %l size modifier
14416 is used. Update the commentary.
14418 * eval.c (verror): Simplify calculation of size_t.
14420 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14423 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14425 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14428 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14430 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14431 This makes this file independent of the recent pseudovector change.
14433 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14435 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14437 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14438 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14439 Remove unused local.
14440 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14442 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14443 GCC 4.6.0 optimizes based on type-based alias analysis.
14444 For example, if b is of type struct buffer * and v of type struct
14445 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14446 != &v->size, and therefore "v->size = 1; b->size = 2; return
14447 v->size;" must therefore return 1. This assumption is incorrect
14448 for Emacs, since it type-puns struct Lisp_Vector * with many other
14449 types. To fix this problem, this patch adds a new type struct
14450 vectorlike_header that documents the constraints on layout of vectors
14451 and pseudovectors, and helps optimizing compilers not get fooled
14452 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14453 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14454 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14456 (XSETPVECTYPE): Rewrite in terms of new macro.
14457 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14458 This is a bit clearer, and further avoids the possibility of
14459 undesirable aliasing.
14460 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14461 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14462 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14463 since Lisp_Subr is a special case (no "next" field).
14464 (ASIZE): Now uses header.size rather than size.
14465 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14466 to avoid the hassle of writing XVECTOR (foo)->header.size.
14467 (struct vectorlike_header): New type.
14468 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14469 object, to help avoid aliasing.
14470 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14471 (SUBRP): Likewise, since Lisp_Subr is a special case.
14472 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14473 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14474 (struct Lisp_Hash_Table): Combine first two members into a single
14475 struct vectorlike_header member. All uses of "size" and "next" members
14476 changed to be "header.size" and "header.next".
14477 * buffer.h (struct buffer): Likewise.
14478 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14479 * frame.h (struct frame): Likewise.
14480 * process.h (struct Lisp_Process): Likewise.
14481 * termhooks.h (struct terminal): Likewise.
14482 * window.c (struct save_window_data, struct saved_window): Likewise.
14483 * window.h (struct window): Likewise.
14484 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14485 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14486 * buffer.c (init_buffer_once): Likewise.
14487 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14489 * process.c (Fformat_network_address): Use local var for size,
14492 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14494 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14495 * data.c (atof): Remove decl; no longer used or needed.
14496 (digit_to_number): Move to lread.c.
14497 (Fstring_to_number): Use new string_to_number function, to be
14498 consistent with how the Lisp reader treats infinities and NaNs.
14499 Do not assume that floating-point numbers represent EMACS_INT
14500 without losing information; this is not true on most 64-bit hosts.
14501 Avoid double-rounding errors, by insisting on integers when
14502 parsing non-base-10 numbers, as the documentation specifies.
14503 * lisp.h (string_to_number): New decl, replacing ...
14504 (isfloat_string): Remove.
14505 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14506 (read1): Do not accept +. and -. as integers; this
14507 appears to have been a coding error. Similarly, do not accept
14508 strings like +-1e0 as floating point numbers. Do not report
14509 overflow for integer overflows unless the base is not 10 which
14510 means we have no simple and reliable way to continue.
14511 Break out the floating-point parsing into a new
14512 function string_to_number, so that Fstring_to_number parses
14513 floating point numbers consistently with the Lisp reader.
14514 (digit_to_number): Move here from data.c. Make it static inline.
14515 (E_CHAR, EXP_INT): Remove, replacing with ...
14516 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14517 (string_to_number): New function, replacing isfloat_string.
14518 This function checks for valid syntax and produces the resulting
14519 Lisp float number too. Rework it so that string-to-number
14520 no longer mishandles examples like "1.0e+". Use strtoumax,
14521 so that overflow for non-base-10 numbers is reported only when
14522 there's no portable and simple way to convert to floating point.
14524 * textprop.c (set_text_properties_1): Rewrite for clarity,
14525 and to avoid GCC warning about integer overflow.
14527 * intervals.h (struct interval): Use EMACS_INT for members
14528 where EMACS_UINT might cause problems. See
14529 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14530 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14531 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14533 (offset_intervals): Tell GCC not to worry about length overflow
14534 when negating a negative length.
14536 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14537 (overrun_check_free): Likewise.
14539 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14540 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14543 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14544 (gnutls_make_error): Rename local to avoid shadowing.
14545 (gnutls_emacs_global_deinit): ifdef out; not used.
14546 (Fgnutls_boot): Use const for pointer to readonly storage.
14547 Comment out unused local. Fix pointer signedness problems.
14549 * lread.c (openp): Don't stuff size_t into an 'int'.
14550 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14551 about possible signed overflow.
14553 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14554 (GDK_KEY_g): Don't define if already defined.
14555 (xg_prepare_tooltip): Avoid pointer signedness problem.
14556 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14558 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14559 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14561 * xfns.c (Fx_window_property): Simplify a bit,
14562 to make a bit faster and to avoid GCC 4.6.0 warning.
14563 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14565 * fns.c (internal_equal): Don't assume size_t fits in int.
14567 * alloc.c (compact_small_strings): Tighten assertion a little.
14569 Replace pEd with more-general pI, and fix some printf arg casts.
14570 * lisp.h (pI): New macro, generalizing old pEd macro to other
14571 conversion specifiers. For example, use "...%"pI"d..." rather
14572 than "...%"pEd"...".
14573 (pEd): Remove. All uses replaced with similar uses of pI.
14574 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14575 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14576 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14577 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14578 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14579 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14580 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14582 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14583 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14584 * print.c (safe_debug_print, print_object): Likewise.
14585 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14587 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14588 avoiding the 0 flag, which is not portable.
14589 * process.c (Fmake_network_process): Use pI to avoid cast.
14590 * region-cache.c (pp_cache): Likewise.
14591 * xdisp.c (decode_mode_spec): Likewise.
14592 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14593 behavior on 64-bit hosts with printf arg.
14594 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14595 (x_stop_queuing_selection_requests): Likewise.
14596 (x_get_window_property): Don't truncate byte count to an 'int'
14599 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14600 here, since it parses constructs like leading '-' and spaces,
14601 which are not wanted; and it overflows with large numbers.
14602 Instead, simply match F[0-9]+, which is what is wanted anyway.
14604 * alloc.c: Remove unportable assumptions about struct layout.
14605 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14606 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14607 (allocate_vectorlike, make_pure_vector): Use the new macros,
14608 plus offsetof, to remove unportable assumptions about struct layout.
14609 These assumptions hold on all porting targets that I know of, but
14610 they are not guaranteed, they're easy to remove, and removing them
14611 makes further changes easier.
14613 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14614 This doesn't fix a bug but makes the code clearer.
14615 (string_overrun_cookie): Now const. Use initializers that
14616 don't formally overflow signed char, to avoid warnings.
14617 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14618 can cause Emacs to crash when string overrun checking is enabled.
14619 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14620 multiple of sizeof (EMACS_INT); it need not be, if
14621 alignof(EMACS_INT) < sizeof (EMACS_INT).
14622 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14624 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
14626 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
14628 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
14630 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
14631 supposed to be handshaking. (Bug#8556)
14632 Reported by Paul Eggert <eggert@cs.ucla.edu>.

14636 * lisp.h (Qdebug): List symbol.
14637 * eval.c (Qdebug): Restore global linkage.
14638 * keyboard.c (debug-on-event): New variable.
14639 (handle_user_signal): Break into debugger when debug-on-event
14640 matches the current signal symbol.
14642 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
14644 * alloc.c (check_sblock, check_string_bytes)
14645 (check_string_free_list): Convert to standard C.
14647 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14649 * w32.c (emacs_gnutls_push): Fix typo.
14651 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14653 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14654 "cast to pointer from integer of different size".
14656 Improve doprnt and its use in verror. (Bug#8545)
14657 * doprnt.c (doprnt): Document the set of format control sequences
14658 supported by the function. Use SAFE_ALLOCA instead of always
14661 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14662 is one byte too soon. Don't use xrealloc; instead xfree and
14665 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14667 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14670 * gnutls.c: Renamed global_initialized to
14671 gnutls_global_initialized. Added internals for the
14672 :verify-hostname-error, :verify-error, and :verify-flags
14673 parameters of `gnutls-boot' and documented those parameters in the
14674 docstring. Start callback support.
14675 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14676 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14677 on error. Return error code.
14678 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
14679 (emacs_gnutls_read): Likewise.
14680 (Fgnutls_boot): Return handshake error code.
14681 (emacs_gnutls_handle_error): New function.
14682 (wsaerror_to_errno): Likewise.
14684 * w32.h (emacs_gnutls_pull): Add prototype.
14685 (emacs_gnutls_push): Likewise.
14687 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
14688 (emacs_gnutls_push): Likewise.
14690 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
14692 * process.c (wait_reading_process_output): Check if GnuTLS
14693 buffered some data internally if no FDs are set for TLS
14696 * makefile.w32-in (OBJ2): Add gnutls.$(O).
14697 (LIBS): Link to USER_LIBS.

14702 * xdisp.c (handle_single_display_spec): Rename the
14703 display_replaced_before_p argument into display_replaced_p, to
14704 make it consistent with the commentary. Fix typos in the
14707 * textprop.c (syms_of_textprop): Remove dead code.
14708 (copy_text_properties): Delete obsolete commentary about an
14709 interface that was deleted long ago. Fix typos in the description

14713 to changes in oldXMenu/XMenu.h from 2011-04-16.
14714 <menu_help_message, prev_menu_help_message>: Constify.
14715 (IT_menu_make_room): menu->help_text is now `const char **';

14719 to changes in oldXMenu/XMenu.h from 2011-04-16.
14720 (struct XMenu): Declare `help_text' `const char **'.

15005 * process.c (send_process): Adjust to the new signatures of
15006 emacs_write and emacs_gnutls_write. Do not attempt to store

15200 * font.h (font_close_object): Remove.
15201 * fontset.c (FONTSET_OBJLIST): Remove.
15202 (free_realized_fontset) #if-0 the body, which does nothing.
15203 (face_suitable_for_char_p): #if-0, as it's never called.
15204 * fontset.h (face_suitable_for_char_p): Remove decl.
15205 * xfaces.c (face_at_string_position):
15206 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
15207 since 0 is always ASCII.
15209 * fns.c (weak_hash_tables): Now static.
15211 * fileio.c: Make symbols static if they're not exported.
15212 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

15226 * lisp.h (fatal_error_signal_hook): Remove decl.
15227 (fatal_error_signal): Declare only if FLOAT_CATCH_SIGKILL.

15230 * editfns.c, lisp.h (get_operating_system_release): Remove.
15231 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
15232 worth the hassle of breaking this out.
15234 * xterm.c: Make symbols static if they're not exported.
15235 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
15236 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

15336 * lisp.h: Remove these decls.
15338 * buffer.c (buffer_count): Remove unused var.
15340 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

15347 * atimer.h (run_all_atimers): Remove; not exported.
15349 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
15350 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
15351 was inaccessible from Lisp.
15352 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
15353 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
15355 alloc.c: Import and export fewer symbols, and remove unused items.
15356 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
15358 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
15359 it's not optimized away by whole-program optimization.
15360 (message_enable_multibyte, free_misc): Remove.
15361 (catchlist, handlerlist, mark_backtrace):
15362 Declare only if BYTE_MARK_STACK.

15371 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15372 (mark_backtrace): Define only if BYTE_MARK_STACK.
15373 * xdisp.c (message_enable_multibyte): Now static.
15375 Declare Lisp_Object Q* variables to be 'static' if not exported.
15376 This makes it easier for human readers (and static analyzers)
15377 to see whether these variables are used from other modules.
15378 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15379 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15380 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

15388 Remove decls of unexported vars.
15389 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15391 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15393 Make Emacs functions such as Fatom 'static' by default.
15394 This makes it easier for human readers (and static analyzers)
15395 to see whether these functions can be called from other modules.
15396 DEFUN now defines a static function. To make the function external
15397 so that it can be used in other C modules, use the new macro DEFUE.
15398 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15399 (Finit_image_library):
15400 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15401 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15402 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15403 Remove decls, since these functions are now static.
15404 (Funintern, Fget_internal_run_time): New decls, since these functions
15405 were already external.
15407 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15408 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

15414 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15415 Mark functions with DEFUE instead of DEFUN,
15416 if they are used in other modules.
15417 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15418 decls for now-static functions.
15419 * buffer.h (Fdelete_overlay): Remove decl.
15420 * callproc.c (Fgetenv_internal): Mark as internal.
15421 * composite.c (Fremove_list_of_text_properties): Remove decl.

15429 * image.c (Finit_image_library): New forward static decl.
15430 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15431 * intervals.h (Fprevious_property_change):
15432 (Fremove_list_of_text_properties): Remove decls.
15433 * keyboard.c (Fthis_command_keys): Remove decl.
15434 (Fcommand_execute): New forward static decl.

15436 (Fcopy_keymap): Now static.
15437 * keymap.h (Flookup_key): Remove decl.
15438 * process.c (Fget_process): New forward static decl.
15439 (Fprocess_datagram_address): Mark as internal.

15450 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15452 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15455 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15457 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15458 when at ZV. (Bug#8487)
15460 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15462 * charset.c (Fclear_charset_maps): Use xfree instead of free.

15465 * sound.c (sound_cleanup, alsa_close): Likewise.
15466 * termcap.c (tgetent): Likewise.
15467 * xfns.c (x_default_font_parameter): Likewise.
15468 * xsettings.c (read_and_apply_settings): Likewise.
15470 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15471 (overrun_check_free): Protoize.
15473 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15475 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15476 since callers should never pass a negative size.
15477 Change the signature to match that of plain 'read' and 'write'; see
15478 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15479 * lisp.h: Update prototypes of emacs_write and emacs_read.
15481 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15483 * xdisp.c (redisplay_window): Don't try to determine the character
15484 position of the scroll margin if the window start point w->startp
15485 is outside the buffer's accessible region. (Bug#8468)
15487 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15489 Fix write-region and its subroutines for buffers > 2GB.
15490 * fileio.c (a_write, e_write): Modify declaration of arguments and
15491 local variables to support buffers larger than 2GB.
15492 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15494 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15495 argument, local variables, and return value.
15497 * lisp.h: Update prototypes of emacs_write and emacs_read.
15499 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15501 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15503 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15505 Fix more problems found by GCC 4.6.0's static checks.
15507 * xdisp.c (vmessage): Use a better test for character truncation.
15509 * charset.c (load_charset_map): <, not <=, for optimization,
15510 and to avoid potential problems with integer overflow.
15511 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15512 * casetab.c (set_identity, shuffle): Likewise.
15513 * editfns.c (Fformat): Likewise.
15514 * syntax.c (skip_chars): Likewise.
15516 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15517 This also lets GCC 4.6.0 generate slightly better loop code.
15519 * callint.c (Fcall_interactively): <, not <=, for optimization.
15520 (Fcall_interactively): Count the number of arguments produced,
15521 not the number of arguments given. This is simpler and lets GCC
15522 4.6.0 generate slightly better code.
15524 * ftfont.c: Distingish more carefully between FcChar8 and char.
15525 The previous code passed unsigned char * to a functions like
15526 strlen and xstrcasecmp that expect char *, which does not
15527 conform to the C standard.
15528 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15529 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15530 char * when the C standard requires it.
15532 * keyboard.c (read_char): Remove unused var.
15534 * eval.c: Port to Windows vsnprintf (Bug#8435).
15535 Include <limits.h>.
15536 (SIZE_MAX): Define if the headers do not.
15537 (verror): Do not give up if vsnprintf returns a negative count.
15538 Instead, grow the buffer. This ports to Windows vsnprintf, which
15539 does not conform to C99. Problem reported by Eli Zaretskii.
15540 Also, simplify the allocation scheme, by avoiding the need for
15541 calling realloc, and removing the ALLOCATED variable.
15543 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15545 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15546 But keep the doprint source code for now, as we might revamp it
15547 and use it again (Bug#8435).
15548 * lisp.h (doprnt): Remove.
15549 * Makefile.in (base_obj): Remove doprnt.o.
15550 * deps.mk (doprnt.o): Remove.
15552 error: Print 32- and 64-bit integers portably (Bug#8435).
15553 Without this change, on typical 64-bit hosts error ("...%d...", N)
15554 was used to print both 32- and 64-bit integers N, which relied on
15555 undefined behavior.
15556 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15557 * lisp.h (error, verror): Mark as printf-like functions.
15558 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15559 Report overflow in size calculations when allocating printf buffer.
15560 Do not truncate output string at its first null byte.
15561 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15562 Truncate the output at a character boundary, since vsnprintf does not
15564 * charset.c (check_iso_charset_parameter): Convert internal
15565 character to string before calling 'error', since %c now has the
15567 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15568 overflow when computing char to be passed to 'error'. Do not
15569 pass Lisp_Object to 'error'; pass the integer instead.
15570 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15571 formatted with plain %d.
15573 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15575 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15577 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15579 * xterm.c (x_catch_errors): Remove duplicate declaration.
15581 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15583 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15585 2011-04-10 Jim Meyering <meyering@redhat.com>
15587 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15588 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15589 return ssize_t not "int", and use size_t as the buffer length.
15590 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15591 * gnutls.h: Update declarations.
15592 * process.c (read_process_output): Use ssize_t, to match.
15593 (send_process): Likewise.
15595 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15597 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15599 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15601 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15602 Use unsigned char, to match FcChar8 type definition.
15604 * xterm.c (handle_one_xevent):
15605 * xmenu.c (create_and_show_popup_menu):
15606 * xselect.c (x_decline_selection_request)
15607 (x_reply_selection_request): Avoid type-punned deref of X events.
15609 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15611 Fix some uses of `int' instead of EMACS_INT.
15612 * search.c (string_match_1, fast_string_match)
15613 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15614 (scan_buffer, find_next_newline_no_quit)
15615 (find_before_next_newline, search_command, Freplace_match)
15616 (Fmatch_data): Make some `int' variables be EMACS_INT.
15618 * xdisp.c (display_count_lines): 3rd argument and return value now
15619 EMACS_INT. All callers changed.

15639 (encode_invocation_designation): Last argument P_NCHARS is now
15641 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.

15665 instead of using internal_with_output_to_temp_buffer.
15666 (Qhelp_form_show): New var.
15667 (syms_of_keyboard): Use DEFSYM macro.
15669 * print.c (internal_with_output_to_temp_buffer): Function deleted.

15705 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15707 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15708 This avoids several warnings with gcc -Wstrict-overflow.
15709 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15710 directly, rather than having caller test rule sign. This avoids
15711 some unnecessary tests.
15712 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15713 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15714 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15716 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15717 (xfont_open): Avoid unnecessary tests.
15719 * composite.c (composition_gstring_put_cache): Use unsigned integer.
15721 * composite.h, composite.c (composition_gstring_put_cache):
15722 Use EMACS_INT, not int, for length.
15724 * composite.h (COMPOSITION_DECODE_REFS): New macro,
15725 breaking out part of COMPOSITION_DECODE_RULE.
15726 (COMPOSITION_DECODE_RULE): Use it.
15727 * composite.c (get_composition_id): Remove unused local vars,
15728 by using the new macro.
15730 * textprop.c (set_text_properties_1): Change while to do-while,
15731 since the condition is always true at first.
15733 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15734 (interval_deletion_adjustment): Return unsigned value.
15737 * process.c (list_processes_1, create_pty, read_process_output):
15738 (exec_sentinel): Remove vars that were set but not used.
15739 (create_pty): Remove unnecessary "volatile"s.
15740 (Fnetwork_interface_info): Avoid possibility of int overflow.

15753 * print.c (print_error_message): Avoid int overflow.
15755 * font.c (font_list_entities): Redo for clarity,
15756 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15758 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15759 (font_score): Avoid potential overflow in diff calculation.

15762 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15764 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15766 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15767 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15768 can always succeed if overflow has undefined behavior.
15770 * search.c (boyer_moore, wordify): Remove vars set but not used.
15771 (wordify): Omit three unnecessary tests.
15773 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15774 All callers changed. This avoids the need for an unused var.
15776 * casefiddle.c (casify_region): Remove var that is set but not used.
15778 * dired.c (file_name_completion): Remove var that is set but not used.
15780 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
15782 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
15783 (Finsert_file_contents): Remove unnecessary code checking fd.
15785 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
15786 Check for integer overflow on size calculations.
15788 * buffer.c (Fprevious_overlay_change): Remove var that is set
15791 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
15792 Remove vars that are set but not used.
15793 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
15794 (timer_check_2): Mark vars as initialized.
15796 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
15798 * image.c (lookup_image): Remove var that is set but not used.
15799 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
15801 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
15802 that are set but not used.
15804 * xfns.c (make_invisible_cursor): Don't return garbage
15805 if XCreateBitmapFromData fails (Bug#8410).
15807 * xselect.c (x_get_local_selection, x_handle_property_notify):
15808 Remove vars that are set but not used.
15810 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
15811 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
15813 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
15814 Remove var that is set but not used.
15815 (scroll_bar_windows_size): Now size_t, not int.
15816 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
15817 Check for overflow.
15819 * xfaces.c (realize_named_face): Remove vars that are set but not used.
15820 (map_tty_color) [!defined MSDOS]: Likewise.
15822 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
15824 * coding.c: Remove vars that are set but not used.
15825 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
15826 All callers changed.
15827 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
15828 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
15829 (decode_coding_charset): Remove vars that are set but not used.
15831 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
15832 that is set but not used.
15834 * print.c (print_object): Remove var that is set but not used.
15836 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
15837 The gnulib version avoids calling malloc in the usual case,
15838 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
15839 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
15840 * filelock.c (current_lock_owner): Likewise.
15841 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
15842 * sysdep.c: Include allocator.h, careadlinkat.h.
15843 (emacs_no_realloc_allocator): New static constant.
15844 (emacs_readlink): New function.
15845 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
15846 ../lib/careadlinkat.h.
15848 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
15850 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
15851 first non-nil return value).
15853 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
15855 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
15856 if not defined (Bug#8403).
15858 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
15860 * xdisp.c (display_count_lines): Remove parameter `start',
15861 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
15862 (get_char_face_and_encoding): Remove parameter `multibyte_p',
15863 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

15865 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
15866 and thereabouts. All callers changed.
15867 (get_per_char_metric): Remove parameter `f', unused since
15868 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
15870 2011-04-02 Jim Meyering <meyering@redhat.com>
15872 do not dereference NULL upon failed strdup
15873 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
15874 (ns_get_family): Likewise.
15876 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
15878 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
15880 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
15882 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
15885 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
15887 Add lexical binding.
15889 * window.c (Ftemp_output_buffer_show): New fun.
15890 (Fsave_window_excursion):
15891 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
15893 * lread.c (lisp_file_lexically_bound_p): New function.
15894 (Fload): Bind Qlexical_binding.
15895 (readevalloop): Remove `evalfun' arg.
15896 Bind Qinternal_interpreter_environment.
15897 (Feval_buffer): Bind Qlexical_binding.
15898 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
15900 (syms_of_lread): Declare `lexical-binding'.
15902 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
15904 * keyboard.c (eval_dyn): New fun.
15905 (menu_item_eval_property): Use it.
15907 * image.c (parse_image_spec): Use Ffunctionp.
15909 * fns.c (concat, mapcar1): Accept byte-code-functions.
15911 * eval.c (Fsetq): Handle lexical vars.
15912 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
15913 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
15914 (FletX, Flet): Obey lexical binding.
15915 (Fcommandp): Handle closures.
15916 (Feval): New `lexical' arg.
15917 (eval_sub): New function extracted from Feval. Use it almost
15918 everywhere where Feval was used. Look up vars in lexical env.
15920 (Ffunctionp): Move from subr.el.
15921 (Ffuncall): Handle closures.
15922 (apply_lambda): Remove `eval_flags'.
15923 (funcall_lambda): Handle closures and new byte-code-functions.
15924 (Fspecial_variable_p): New function.
15925 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
15926 but without exporting it to Lisp.
15928 * doc.c (Fdocumentation, store_function_docstring):
15929 * data.c (Finteractive_form): Handle closures.
15931 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
15934 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
15936 (exec_byte_code): New function extracted from Fbyte_code to handle new
15937 calling convention for byte-code-functions. Add new byte-codes.
15939 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
15941 * alloc.c (Fmake_symbol): Init new `declared_special' field.
15943 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
15945 * xdisp.c (redisplay_internal): Fix prototype.
15947 2011-03-31 Eli Zaretskii <eliz@gnu.org>
15949 * xdisp.c (SCROLL_LIMIT): New macro.
15950 (try_scrolling): Use it when setting scroll_limit.
15951 Limit scrolling to 100 screen lines.
15952 (redisplay_window): Even when falling back on "recentering",
15953 position point in the window according to scroll-conservatively,
15954 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
15956 (try_scrolling): When point is above the window, allow searching
15957 as far as scroll_max, or one screenful, to compute vertical
15958 distance from PT to the scroll margin position. This prevents
15959 try_scrolling from unnecessarily failing when
15960 scroll-conservatively is set to a value slightly larger than the
15961 window height. Clean up the case of PT below the margin at bottom
15962 of window: scroll_max can no longer be INT_MAX. When aggressive
15963 scrolling is in use, don't let point enter the opposite scroll
15964 margin as result of the scroll.
15965 (syms_of_xdisp) <scroll-conservatively>: Document the
15966 threshold of 100 lines for never-recentering scrolling.
15968 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
15970 * dispextern.h (move_it_by_lines):
15971 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
15972 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
15973 (message_log_check_duplicate): Remove parameters `prev_bol' and
15974 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
15975 (redisplay_internal): Remove parameter `preserve_echo_area',
15976 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
15978 * indent.c (Fvertical_motion):
15979 * window.c (window_scroll_pixel_based, Frecenter):
15980 Don't pass `need_y_p' to `move_it_by_lines'.
15982 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
15984 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
15985 steal a few bits to be more compact.
15986 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
15987 Remove unneeded casts.
15989 * bytecode.c (Fbyte_code): CAR and CDR can GC.
15991 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
15993 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
15994 binding" message (bug#7967).
15996 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
15998 Fix more problems found by GCC 4.6.0's static checks.
16000 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16001 Remove unused local var.
16003 * editfns.c (Fmessage_box): Remove unused local var.
16005 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16006 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16007 Omit unused local vars.
16008 * window.c (shrink_windows): Omit unused local var.
16009 * menu.c (digest_single_submenu): Omit unused local var.
16010 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16011 Omit unused local var.
16013 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16014 Don't assume string length fits in int.
16015 (keyremap_step, read_key_sequence): Use size_t for sizes.
16016 (read_key_sequence): Don't check last_real_key_start redundantly.
16018 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16019 instead of alloca (Bug#8344).
16021 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16022 (Fbacktrace_frame): Don't assume nframes fits in int.
16024 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
16026 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
16029 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16031 * cm.c (calccost): Turn while-do into do-while, for clarity.
16033 * keyboard.c (syms_of_keyboard): Use the same style as later
16034 in this function when indexing through an array. This also
16035 works around GCC bug 48267.
16037 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16039 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16041 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16042 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16044 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16045 This avoids undefined behavior on integer overflow, and is a bit
16046 more convenient anyway since it is compared to a size_t variable.
16048 Variadic C functions now count arguments with size_t, not int.
16049 This avoids an unnecessary limitation on 64-bit machines, which
16050 caused (substring ...) to crash on large vectors (Bug#8344).
16051 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
16052 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
16053 All variadic functions and their callers changed accordingly.
16054 (struct gcpro.nvars): Now size_t, not int. All uses changed.

16059 (funcall_lambda, mark_backtrace): Likewise.
16060 * fns.c (concat): Likewise.
16061 * frame.c (x_set_frame_parameters): Likewise.
16062 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16063 0 if not found, not -1. All callers changed.
16065 * alloc.c (garbage_collect): Don't assume stack size fits in int.

16280 Fix more problems found by GCC 4.5.2's static checks.
16282 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16283 the first time through the loop, since we know p0 < p1 then.
16284 This also avoids a gcc -Wstrict-overflow warning.
16286 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16287 leading to a memory leak, possible in functions like
16288 load_charset_map_from_file that can allocate an unbounded number
16289 of objects (Bug#8318).
16291 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16292 that could (at least in theory) be that large.
16294 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16295 This is less likely to overflow, and avoids undefined behavior if
16296 overflow does occur. All callers changed. Use strtoul to scan
16297 for the unsigned long integer.

16314 * process.c (Fmake_network_process): Use socklen_t, not int,
16315 where POSIX says socklen_t is required in portable programs.
16316 This fixes a porting bug on hosts like 64-bit HP-UX, where
16317 socklen_t is wider than int (Bug#8277).
16318 (Fmake_network_process, server_accept_connection):
16319 (wait_reading_process_output, read_process_output):
16322 * process.c: Rename or move locals to avoid shadowing.

16334 Include tparam.h instead, since it declares them.
16335 * cm.h (PC): Remove extern decl; tparam.h now does this.
16336 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16337 * terminfo.c: Include tparam.h, to check interfaces.
16338 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16339 (tparam): Adjust signature to match interface in tparam.h;
16340 this removes some undefined behavior. Check that outstring and len
16341 are zero, which they always are with Emacs.
16342 * tparam.h (PC, BC, UP): New extern decls.
16344 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16345 (xftfont_open): Rename locals to avoid shadowing.

16363 (composition_update_it): Mark var as initialized.
16364 (find_automatic_composition): Mark vars as initialized,
16365 with a FIXME (Bug#8290).

16384 Fix pointer signedness.
16385 (alsa_choose_format): Remove unused local var.
16386 (wav_play): Initialize a variable to 0, to prevent undefined
16387 behavior (Bug#8278).
16389 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16391 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16393 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16394 clobbering (Bug#8298).
16395 * sysdep.c (sys_subshell): Likewise.
16396 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16398 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16399 This should get cleaned up, so that child_setup has the
16400 same signature on all platforms.
16402 * callproc.c (call_process_cleanup): Now static.
16403 (relocate_fd): Rename locals to avoid shadowing.
16405 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16407 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16408 not to be necessary, and produces flickering.
16410 2011-03-20 Glenn Morris <rgm@gnu.org>
16412 * config.in: Remove file.
16414 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

16459 Define only if needed.
16461 * unexelf.c (unexec): Name an expression,
16462 to avoid gcc -Wbad-function-cast warning.
16463 Use a different way to cause a compilation error if anyone uses
16464 n rather than nn, a way that does not involve shadowing.
16465 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16467 * deps.mk (unexalpha.o): Remove; unused.

16532 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16533 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16534 some of which prompt warnings from gcc -Wbad-function-cast.
16535 (Fformat_time_string, Fencode_time, Finsert_char):
16536 (Ftranslate_region_internal, Fformat):

16564 (Fmemory_limit): Cast sbrk's returned value to char *.
16566 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16567 avoids undefined behavior in theory.
16569 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16571 Use functions, not macros, for up- and down-casing (Bug#8254).
16572 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16573 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16574 to use the following functions instead of these macros.
16575 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16576 EMACS_INT, since callers assume the returned value fits in int.
16577 (upcase1): Likewise, for UPCASE_TABLE.
16578 (uppercasep, lowercasep, upcase): New static inline functions.
16579 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

16589 (regex_compile, re_match_2_internal): Mark locals as initialized.
16590 (RETALLOC_IF): Define only if needed.
16591 (WORDCHAR_P): Likewise. This one is never needed, but is used
16592 only in a comment talking about a compiler bug, so put inside
16593 the #if 0 of that comment.
16594 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16595 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

16621 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16622 New macros, so that the caller can use some names other than
16623 gcpro1, gcpro2, etc.
16624 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16626 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16627 argument, for consistency with GCPRO2_VAR, etc: it is now the
16628 prefix of the variable, not the variable itself. All uses
16630 * dired.c (directory_files_internal, file_name_completion):
16631 Rename locals to avoid shadowing.
16633 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16634 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16635 dired.c's scmp function, had undefined behavior.
16636 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16637 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16638 * buffer.h: ... to here, because these macros use current_buffer,
16639 and the new implementation with inline functions needs to have
16640 current_buffer in scope now, rather than later when the macros
16642 (downcase, upcase1): New static inline functions.
16643 (DOWNCASE, UPCASE1): Reimplement using these functions.
16644 This avoids undefined behavior in expressions like
16645 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16646 from race conditions in accessing the global variables
16647 case_temp1 and case_temp2.
16648 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16649 * lisp.h (case_temp1, case_temp2): Remove their decls.
16650 * character.h (ASCII_CHAR_P): Move from here ...
16651 * lisp.h: ... to here, so that the inline functions mentioned
16652 above can use them.
16654 * dired.c (directory_files_internal_unwind): Now static.
16656 * fileio.c (file_name_as_directory, directory_file_name):
16657 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16659 (file_name_as_directory): Use const pointers when appropriate.
16660 (Fexpand_file_name): Likewise. In particular, newdir might
16661 point at constant storage, so make it a const pointer.
16662 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16663 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16665 (Fset_file_times, Finsert_file_contents, auto_save_error):

16670 to avoid shadowing.
16672 * marker.c (bytepos_to_charpos): Remove; unused.
16674 * lisp.h (verify_bytepos, count_markers): New decls,
16675 so that gcc does not warn that these functions aren't declared.
16677 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16678 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16679 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16680 (copy_text): Remove unused local var.
16682 * filelock.c (within_one_second): Now static.
16683 (lock_file_1): Rename local to avoid shadowing.
16685 * buffer.c (fix_overlays_before): Mark locals as initialized.
16686 (fix_start_end_in_overlays): Likewise. This function should be
16687 simplified by using pointers-to-pointers, but that's a different
16689 (switch_to_buffer_1): Now static.
16690 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16691 (report_overlay_modification): Rename locals to avoid shadowing.

16696 to suppress a gcc -Wclobbered warning that does not seem to be right.
16697 (MAXPATHLEN): Define only if needed.
16699 * process.c (serial_open, serial_configure): Move decls from here ...
16700 * systty.h: ... to here, so that they can be checked.
16702 * fns.c (get_random, seed_random): Move extern decls from here ...
16703 * lisp.h: ... to here, so that they can be checked.
16705 * sysdep.c (reset_io): Now static.

16714 (describe_map_tree):
16715 Rename locals to avoid shadowing.

16865 1152921504606846976) returns the obviously-bogus value (-948597
16866 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
16867 reports time overflow. See
