1 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3 Convenient macro to check whether the buffer is live.
4 * buffer.h (BUFFER_LIVE_P): New macro.
5 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
8 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
11 composition cases (Bug#12364).
13 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
14 overhang of succeeding glyphs overlapping box cursor.
16 * w32term.c (x_draw_glyph_string): Likewise.
18 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
20 Simplify, document, and port floating-point (Bug#12381).
21 The porting part of this patch fixes bugs on non-IEEE platforms
22 with frexp, ldexp, logb.
23 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
25 * floatfns.c: Simplify discussion of functions that Emacs doesn't
26 support, by removing commented-out code and briefly listing the
27 C89 functions excluded. The commented-out stuff was confusing
28 maintenance, e.g., we thought we needed cbrt but it was commented out.
29 (logb): Remove decl; no longer needed.
30 (isfinite): New macro, if not already supplied.
31 (isnan): Don't replace any existing macro.
32 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
33 are present on all C89 platforms.
34 (Ffrexp): Do not special-case zero, as frexp does the right thing
36 (Flogb): Do not use logb, as it doesn't have the desired meaning
37 on hosts that use non-base-2 floating point. Instead, stick with
38 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
39 frexp, to avoid getting an unspecified result.
41 * xdisp.c (Qinhibit_debug_on_message): Now static.
43 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
45 * nsterm.m (ns_update_begin): Set clip path to whole view by using
46 NSBezierPath (Bug#12131).
48 2012-09-10 Chong Yidong <cyd@gnu.org>
50 * fns.c (Fdelq, Fdelete): Doc fix.
52 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
54 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
55 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
57 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
59 * lisp.h (make_lisp_ptr): New macro to replace XSET.
60 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
63 2012-09-09 Eli Zaretskii <eliz@gnu.org>
65 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
66 left fringe if the window has a left margin. This avoids leaving
67 traces of the cursor because its leftmost pixel is not drawn over.
69 * dispnew.c (update_window_line): When the left margin area of a
70 screen line is updated, set the redraw_fringe_bitmaps_p flag of
71 that screen line. (Bug#12277)
73 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
75 Assume C89 or later for math functions (Bug#12381).
76 This simplifies the code, and makes it a bit smaller and faster,
77 and (most important) makes it easier to clean up signal handling
78 since we can stop worring about floating-point exceptions in
79 library code. That was a problem before C89, but the problem
80 went away many years ago on all practical Emacs targets.
81 * data.c, image.c, lread.c, print.c:
82 Don't include <math.h>; no longer needed.
83 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
84 might be autoconfigured, as that never happens.
86 * doprnt.c (DBL_MAX_10_EXP):
88 Remove. C89 or later always defines these.
89 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
90 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
91 (arith_error, domain_error, domain_error2):
92 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
93 no longer needed -- we simply return what C returns. All uses removed.
94 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
96 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
97 Remove. All uses expanded, as these macros are no longer used
98 more than once and are now more trouble than they're worth.
99 (Ftan): Use tan, not sin / cos.
100 (Flogb): Assume C89 frexp.
101 (fmod_float): Assume C89 fmod.
102 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
103 (init_floatfns): Remove. All uses removed.
105 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
107 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
108 compositeToPoint for OSX < 10.6 (Bug#12390).
110 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
112 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
113 This produces more-accurate results.
115 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
117 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
120 2012-09-08 Chong Yidong <cyd@gnu.org>
122 * syntax.c (Fstring_to_syntax): Doc fix.
124 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
126 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
127 in the internal border.
128 (x_set_window_size): Remove static variables and their usage.
129 (ns_redraw_scroll_bars): Fix NSTRACE arg.
130 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
131 fringe/internal border adjustment (Bug#11052).
132 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
133 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
134 (ns_fix_rect_ibw): Remove.
135 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
136 (ns_dumpglyphs_box_or_relief): Ditto.
137 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
139 (ns_dumpglyphs_image): Ditto.
140 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
142 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
143 their usage. Add fringe_extended_p and its use as in other terms.
144 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
145 scroll bar was removed.
146 (updateFrameSize): New function.
147 (windowDidResize): Move code to updateFrameSize and call it.
149 * nsterm.h (EmacsView): Add updateFrameSize.
151 2012-09-07 Chong Yidong <cyd@gnu.org>
153 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
155 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
157 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
159 More signal-handler cleanup (Bug#12327).
160 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
161 Problem introduced when merging patches. Noted by Eli Zaretskii in
162 <http://bugs.gnu.org/12327#67>.
163 * floatfns.c: Comment fix.
164 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
165 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
166 and anyway the declaration is harmless even if SIGDANGER is not defined.
167 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
168 defined BROKEN_FIONREAD). systty.h formerly did this, but other
169 source files not surprisingly expected syssignal.h to define, or
170 not define, SIGIO, and it's cleaner to do it that way, for consistency.
171 Include <sys/ioctl.h>, for FIONREAD.
172 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
173 This eliminates a problem whereby other files mysteriously had
174 to include "syssignal.h" before including "systty.h" if they
175 wanted to use "#ifdef SIGIO".
177 2012-09-07 Eli Zaretskii <eliz@gnu.org>
179 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
181 * w32.c (sigemptyset): Empty the set.
182 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
184 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
186 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
188 * alloc.c (mark_buffer): Revert unsafe marking optimization.
189 (mark_object): Likewise for frame objects.
191 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
193 * syssignal.h (handle_on_main_thread): Always declare,
194 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
195 This ports to platforms without HAVE_PTHREAD.
197 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
199 Signal-handler cleanup (Bug#12327).
200 Emacs's signal handlers were written in the old 4.2BSD style with
201 sigblock and sigmask and so forth, and this led to some
202 inefficiencies and confusion. Rewrite these to use
203 pthread_sigmask etc. without copying signal sets around. Also,
204 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
205 'signal', and instead use functions that do not attempt to take
206 over the system name space. This patch causes Emacs's text
207 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
208 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
209 Do not include <signal.h> or "syssignal.h", as these
210 modules do not use signals.
211 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
212 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
213 Do not include <signal.h>, as "syssignal.h" does that for us now.
214 * atimer.c (sigmask_atimers): New function.
215 (block_atimers, unblock_atimers): New functions,
216 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
218 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
219 no longer needed here.
220 * emacs.c (main): Inspect existing signal handler with sigaction,
221 so that there's no need to block and unblock SIGHUP.
222 * sysdep.c (struct save_signal): New member 'action', replacing
223 old member 'handler'.
224 (save_signal_handlers, restore_signal_handlers):
225 Use sigaction instead of 'signal' to save and restore.
226 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
227 New function. All users of 'signal' modified to use set_sighandler
228 if they're writeonly, and to use sys_signal if they're read+write.
229 (emacs_sigaction_init, forwarded_signal): New functions.
230 (sys_signal): Remove. All uses replaced by calls to sigaction
231 and emacs_sigaction_init, or by direct calls to 'signal'.
232 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
233 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
234 all uses replaced by pthread_sigmask etc. calls.
235 * syssignal.h: Include <signal.h>.
236 (emacs_sigaction_init, forwarded_signal): New decls.
237 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
238 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
239 (sigmask, sys_sigmask): Remove; no longer needed.
240 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
241 (sigblock, sigunblock, sigfree):
242 (sigsetmask) [!defined sigsetmask]:
243 Remove. All uses replaced by pthread_sigmask.
244 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
245 no longer need to be replaced, and its typical old uses
246 are now done via emacs_sigaction_init and sigaction.
247 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
248 (sys_sigdel): Remove; unused.
249 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
251 2012-09-06 Eli Zaretskii <eliz@gnu.org>
253 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
254 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
256 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
258 Explicitly mark buffer_defaults and buffer_local_symbols.
259 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
260 mark_local_symbols here.
261 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
262 since special buffers aren't marked here any more.
263 (allocate_buffer): Chain new buffer with all_buffers here...
264 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
266 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
267 (syms_of_buffer): Remove staticpro of the above.
268 (init_buffer_once): Set names for buffer_defaults and
269 buffer_local_symbols.
271 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
273 Use bool for booleans in font-related modules.
274 * font.c (font_intern_prop, font_style_to_value)
275 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
276 (generate_otf_features, font_check_otf_features, font_check_otf)
277 (font_match_p, font_list_entities, font_at):
278 * fontset.c (fontset_id_valid_p, reorder_font_vector
279 (fontset_find_font, Fset_fontset_font)
280 (face_suitable_for_char_p) [0]:
281 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
282 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
283 (m17n_flt_initialized, ftfont_shape_by_flt):
284 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
285 * nsfont.m (nsfont_draw):
286 * w32font.c (w32font_draw):
287 * w32term.c (x_draw_glyphless_glyph_string_foreground):
288 Use bool for booleans.
289 * font.h: Adjust to above API changes.
290 (struct font, struct font_driver, struct font_driver_list):
291 Use bool for booleans.
292 (struct font): Remove useless member encoding_type.
294 * fontset.c, xftfont.c: Omit unnecessary static decls.
296 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
298 * alloc.c (mark_object): Revert window marking code
299 since it's unsafe for the Fset_window_configuration.
301 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
303 Fix race conditions with signal handlers and errno (Bug#12327).
304 Be more systematic about preserving errno whenever a signal
305 handler returns, even if it's not in the main thread. Do this by
306 renaming signal handlers to distinguish between signal delivery
307 and signal handling. All uses changed.
308 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
309 * data.c (deliver_arith_signal): Rename from arith_error.
310 * dispnew.c (deliver_window_change_signal): Rename from
311 window_change_signal.
312 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
313 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
314 * keyboard.c (deliver_input_available_signal): Rename from
315 input_available_signal.
316 (deliver_user_signal): Rename from handle_user_signal.
317 (deliver_interrupt_signal): Rename from interrupt_signal.
318 * process.c (deliver_pipe_signal): Rename from send_process_trap.
319 (deliver_child_signal): Rename from sigchld_handler.
320 * atimer.c (handle_alarm_signal):
321 * data.c (handle_arith_signal):
322 * dispnew.c (handle_window_change_signal):
323 * emacs.c (handle_fatal_signal, handle_danger_signal):
324 * keyboard.c (handle_input_available_signal):
325 * keyboard.c (handle_user_signal, handle_interrupt_signal):
326 * process.c (handle_pipe_signal, handle_child_signal):
327 New functions, with the actual signal-handling code taken from the
328 original respective signal handlers, sans the sporadic attempts to
329 preserve errno, since that's now done by handle_on_main_thread.
330 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
331 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
332 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
334 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
335 Move initialization of main_thread to sysdep.c's init_signals.
336 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
337 our usage, and simplifies the mainline code.
338 (record_child_status_change): New static function, as a helper
339 for handle_child_signal, and with most of the old child handler's
341 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
342 (handle_child_signal): Use the above.
343 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
344 Moved here from emacs.c.
345 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
346 code moved here from emacs.c's main function.
347 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
348 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
349 lets callers save and restore errno properly.
351 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
353 Remove redundant or unused things here and there.
354 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
355 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
356 * editfns.c (Fcompare_buffer_substrings): Likewise.
357 * frame.h (struct terminal, struct font_driver_list):
358 Remove redundant declarations.
359 * window.h (Qleft, Qright): Likewise.
361 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
363 Do not mark objects from deleted buffers, windows and frames.
364 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
365 (mark_object): Likewise for windows and frames.
367 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
369 * alloc.c (valid_lisp_object_p): Treat killed buffers,
370 buffer_defaults and buffer_local_symbols as valid objects.
371 Return special value to denote them.
373 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
375 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
376 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
377 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
378 (file_name_absolute_p, Fsubstitute_in_file_name):
379 (check_executable, check_writable, Ffile_accessible_directory_p)
380 (Fset_file_selinux_context, Fdefault_file_modes)
381 (Finsert_file_contents, choose_write_coding_system)
382 (Fwrite_region, build_annotations, a_write, e_write)
384 * filelock.c (boot_time_initialized, get_boot_time)
385 (get_boot_time_1, lock_file_1, within_one_second):
386 * floatfns.c (in_float):
387 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
388 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
389 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
390 * lisp.h (struct Lisp_Hash_Table.cmpfn):
391 * window.c (compare_window_configurations):
392 Use bool for booleans.
393 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
394 (Fdefault_file_modes): Now mode_t, not int, for modes.
395 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
396 (internal_delete_file): Now returns void, not a (boolean) int,
397 since nobody was looking at the return value.
398 * lisp.h, window.h: Adjust to above API changes.
400 * xdisp.c (set_message): Simplify and reindent last change.
402 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
404 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
406 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
408 * eval.c (call_debugger): Make the function non-static so that we
409 can call it from set_message.
411 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
412 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
414 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
416 Give more-useful info on a fatal error (Bug#12328).
417 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
418 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
419 of doing the work ourselves.
420 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
422 (fatal_error_backtrace): New function, taken from the guts
423 of the old fatal_error_signal, but with a new option to output
425 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
426 info about the signal than just its number.
427 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
428 * sysdep.c: Include <execinfo.h>
429 (emacs_backtrace): New function, taken partly from the previous
430 code of the 'die' function.
431 (emacs_abort): Call fatal_error_backtrace rather than abort.
433 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
435 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
436 eager (load-time) macro-expansion.
437 * lisp.mk (lisp): Add macroexp.
439 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
441 Simplify redefinition of 'abort' (Bug#12316).
442 Do not try to redefine the 'abort' function. Instead, redo
443 the code so that it calls 'emacs_abort' rather than 'abort'.
444 This removes the need for the NO_ABORT configure-time macro
445 and makes it easier to change the abort code to do a backtrace.
446 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
447 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
448 Remove; sysdep.c's emacs_abort now takes its place.
449 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
450 'abort' changed to use 'emacs_abort'.
451 * msdos.c (dos_abort) [defined abort]: Remove; not used.
452 (abort) [!defined abort]: Rename to ...
453 (emacs_abort): ... new name.
454 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking

461 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
462 offsets[j].dv, since the y axis of the screen coordinates points
463 down, while the y axis of the font definition coordinates points
464 up. This fixes display of Arabic diacritics such as KASRA and
465 KASRATAN. (Bug#11860)
467 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>

474 * process.c (send_process_trap, send_process):
475 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
476 The underscored versions are up to 30x faster on some hosts.
477 Formerly, the code used setjmp+longjmp sometimes and
478 _setjmp+_longjmp at other times, with no particular reason to
479 prefer setjmp+longjmp.

514 signature just changed from int to bool.
515 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
516 * msdos.c (fatal_error_in_progress): ... from here.

525 That way, we're more likely to catch errors if the interfaces change.
526 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
527 declare xg_mark_data.
528 * dispextern.h (x_frame_parm_handlers):

553 * xterm.c (updating_frame): Remove decl of nonexistent object.
555 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
556 when building globals.h, as the objects that are not built on
557 this host are not needed to compile C files on this host.

561 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

611 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
612 more than one grapheme cluster passed to the shaper: compute the

615 * image.c: Restore mistakenly removed inclusion of w32.h. Without
616 it, GCC doesn't see prototypes of w32_delayed_load, and complains

918 All initializations removed.
919 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
921 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
923 Fix spare memory change (Bug#12286).
924 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
925 (valid_lisp_object_p): Likewise.
927 2012-08-27 Martin Rudalics <rudalics@gmx.at>
929 * window.c (Fset_window_configuration): Record any window's old
930 buffer if it's replaced (see Bug#8789). If the new current
931 buffer doesn't appear in the selected window, go to its old
934 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
936 Special MEM_TYPE_SPARE to denote reserved memory.
937 * alloc.c (enum mem_type): New memory type.
938 (refill_memory_reserve): Use new type for spare memory.
939 This prevents live_cons_p and live_string_p from incorrect
940 detection of uninitialized objects from spare memory as live.
942 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
945 * Makefile.in (.PHONY): versioclean -> versionclean.
947 Remove unused external symbols.
948 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
949 * window.c (Qwindow_valid_p, decode_valid_window):
950 Now static, not extern.
951 * data.c (Qinterval): Remove; unused.
952 (syms_of_data): Do not define 'interval'.
953 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
954 * window.h (decode_valid_window):
957 * character.c, charset.c, chartab.c: Use bool for booleans.
958 * character.c (lisp_string_width, string_count_byte8)
959 (string_escape_byte8):
960 * charset.c (charset_map_loaded, load_charset_map, read_hex):
961 (load_charset_map_from_file, map_charset_chars)
962 (Fdefine_charset_internal, define_charset_internal)
963 (Fdeclare_equiv_charset, find_charsets_in_text)
964 (Ffind_charset_region, char_charset, Fiso_charset):
965 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
966 (sub_char_table_set, sub_char_table_set_range)
967 (char_table_set_range, optimize_sub_char_table)
968 (map_sub_char_table):
969 Use bool for boolean.
970 * character.c (str_to_unibyte): Omit last boolean argument; it was
971 always 0. All callers changed.
972 * character.h, charset.h: Adjust to match previous changes.
973 * character.h (char_printable_p): Remove decl of nonexistent function.
974 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
975 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
976 are all boolean, so make them single-bit bitfields.
978 * lisp.h (ASET): Remove attempt to detect side effects.
979 It was meant to be temporary and it often doesn't work,
980 because when IDX has side effects the behavior of IDX==IDX
981 is undefined. See Stefan Monnier in
982 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
984 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
986 * lisp.h (functionp): New function (extracted from Ffunctionp).
988 * eval.c (Ffunctionp): Use it.
990 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
992 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
993 as that's faster and simpler than static storage. Don't bother
994 with the g_main_context_query overhead if g_main_context_pending
995 says no events are pending.
996 (gfds, gfds_size): Remove these static vars.
997 (xgselect_initialize): Remove; no longer needed.
998 All uses and decls removed.
1000 * emacs.c (fatal_error_signal_hook): Remove.
1001 All uses removed. This leftover from old code was always 0.
1003 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1004 * casefiddle.c (casify_object, casify_region):
1005 * casetab.c (set_case_table):
1006 * category.c, category.h (word_boundary_p):
1007 * category.h (CHAR_HAS_CATEGORY):
1008 Use bool for booleans, instead of int.
1010 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1012 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1014 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1016 On assertion failure, print backtrace if available.
1017 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1018 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1019 * Makefile.in (LIB_EXECINFO): New macro.
1022 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1023 * bytecode.c (exec_byte_code):
1024 * callint.c (check_mark, Fcall_interactively):
1025 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1026 (getenv_internal, sync_process_alive, call_process_exited):
1027 * lisp.h (USE_SAFE_ALLOCA):
1028 Use bool for booleans, instead of int.
1029 * lisp.h, process.h: Adjust prototypes to match above changes.
1030 * callint.c (Fcall_interactively): Don't assume the mark's
1031 offset fits in 'int'.
1033 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1035 * buffer.c, buffer.h: Use bool for boolean.
1036 * buffer.c (reset_buffer_local_variables)
1037 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1038 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1039 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1040 (overlay_touches_p, overlay_strings, Foverlay_put)
1041 (report_overlay_modification, call_overlay_mod_hooks):
1042 (mmap_enlarge, mmap_set_vars):
1043 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1044 Use bool for booleans, instead of int.
1045 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1046 since the 1-or-0 return value is always ignored anyway.
1047 (mmap_initialized_p):
1048 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1049 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1051 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1053 * bidi.c: Use bool for boolean.
1054 This is a bit more readable, and makes the text segment of bidi.o
1055 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1056 Presumably it's faster too.
1057 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1059 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1060 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1061 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1062 (bidi_explicit_dir_char, bidi_level_of_next_char)
1063 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1064 Use bool for booleans, instead of int.
1065 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1066 (bidi_unshelve_cache): Adjust decls to match code.
1068 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1070 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1073 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1075 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1076 * atimer.h: Include <stdbool.h>.
1078 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1080 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1081 compile time tests instead of run time tests on systems that do
1083 (FRAME_MAC_P): Remove leftover from deleted code.
1084 * frame.c (syms_of_frame): Remove leftover from deleted code.
1086 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1088 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1090 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1092 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1093 Otherwise, the compiler complains about (A?B:C) where B is void
1094 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1095 (fontset_add): Return void, for FONTSET_ADD.
1097 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1099 * alloc.c: Use bool for booleans.
1100 (gc_in_progress, abort_on_gc)
1101 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1102 (dont_register_blocks) [GC_MALLOC_CHECK]:
1103 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1104 (check_string_bytes, make_specified_string, memory_full)
1105 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1106 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1107 (mark_stack, valid_pointer_p, make_pure_string)
1108 (Fgarbage_collect, survives_gc_p, gc_sweep):
1109 Use bool for booleans, instead of int.
1110 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1111 Remove unused local.
1112 * alloc.c (PURE_POINTER_P):
1113 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1114 * editfns.c (Fformat):
1115 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1117 * fns.c (sweep_weak_table):
1118 * lisp.h (suppress_checking, push_message, survives_gc_p)
1119 (make_pure_string, gc_in_progress, abort_on_gc):
1120 * lread.c (readchar, read1):
1121 * print.c (Fprin1_to_string):
1122 * xdisp.c (push_message):
1123 Use bool for booleans affected directly or indirectly by
1126 Make recently-introduced setters macros.
1127 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1128 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1129 (set_fontset_default, set_fontset_fallback): Rename from their
1130 upper-case counterparts, and make them functions rather than macros.
1131 This is more consistent with the other recently-introduced setters.
1132 These don't need to be inline, since they're local.
1134 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1136 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1137 the loop (Bug#12247).
1139 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1141 * lisp.h (vcopy): Use memcpy rather than our own loop.
1142 This fixes a performance regression introduced by the recent
1143 addition of vcopy. This means 'vcopy' will need to be modified
1144 for a copying collector, but that's OK. Also, tighten the
1145 checking in the assertion.
1147 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1149 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1150 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1151 non-base glyph for the width of the base character, according to
1152 what x_draw_composite_glyph_string_foreground expects.
1153 Generate WADJUST value according to composition_gstring_width's
1154 expectations, to produce correct width of the composed character.
1155 Reverse the sign of the DU offset produced by ScriptPlace.
1157 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1159 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1161 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1163 Avoid direct writes to contents member of struct Lisp_Vector.
1164 * lisp.h (vcopy): New function to copy data into vector.
1165 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1166 * fns.c (Ffillarray): Use ASET.
1167 * keyboard.c (timer_check_2): Use AREF and ASET.
1168 (append_tool_bar_item, Frecent_keys): Use vcopy.
1169 * lread.c (read_vector): Use ASET.
1170 * msdos.c (Frecent_doskeys): Use vcopy.
1171 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1172 (Finternal_merge_in_global_face): Use ASET and vcopy.
1173 * xfont.c (xfont_list_pattern): Likewise.
1175 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1177 * window.c (Fwindow_point): For the selected window always return
1178 the position of its buffer's point.
1179 (Fset_window_point): For the selected window always go in its
1180 buffer to the specified position.
1182 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1184 Setter macros for fontsets.
1185 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1186 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1187 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1190 2012-08-20 Glenn Morris <rgm@gnu.org>
1192 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1193 Don't assume that `ln -f' works.
1195 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1197 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1198 and later about non-assignments with no effect. See discussion at
1199 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1202 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1204 Inline setter functions for Lisp_Objects slots of struct specbinding.
1205 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1208 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1210 * window.c (select_window): Always make selected window's buffer
1213 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1215 Use AREF and ASET for docstrings of category tables.
1216 * category.h (CATEGORY_DOCSTRING): Use AREF.
1217 (SET_CATEGORY_DOCSTRING): Use ASET.
1218 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1220 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1222 Inline setter functions for hash table members.
1223 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1224 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1225 (set_hash_key_and_value, set_hash_index, set_hash_next)
1226 (set_hash_hash): New functions.
1227 * charset.c, fns.c: Adjust users.
1229 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1231 Inline getter and setter functions for per-buffer values.
1232 * buffer.h (per_buffer_default, set_per_buffer_default)
1233 (per_buffer_value, set_per_buffer_value): New functions.
1234 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1235 * buffer.c, data.c: Adjust users.
1237 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1239 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1241 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1243 Rely on <config.h> + <unistd.h> to declare 'environ',
1244 as gnulib does this if the system doesn't.
1245 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1246 Remove declaration. MS-Windows declares it on stdlib.h which is
1247 included by conf_post.h.
1248 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1249 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1250 * vm-limit.c: Include <unistd.h>, for 'environ'.
1252 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1253 (start_of_data): Remove decl; mem-limits.h provides it.
1255 * xdisp.c (handle_invisible_prop): Make it a bit faster
1256 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1258 2012-08-19 Chong Yidong <cyd@gnu.org>
1260 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1263 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1265 * .gdbinit: Use call instead of set when calling a function in the
1268 * data.c (set_internal): Don't use set_blv_found.
1269 (Fkill_local_variable): Likewise.
1271 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1273 * nsfont.m (ns_ascii_average_width): Ensure the string
1274 ascii_printable is initialized with a null-terminated character
1275 array. Otherwise, it can contain undesired extra characters.
1277 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1279 port new setting code to Sun C 5.8 2005/10/13
1280 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1281 Return void, not Lisp_Object. Otherwise, the compiler
1282 complains about (A?B:C) where B is void and C is Lisp_Object
1283 when compiling CHAR_TABLE_SET, due to the recent change to
1284 the API of sub_char_table_set_contents.
1286 2012-08-18 Chong Yidong <cyd@gnu.org>
1288 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1289 for the string case (Bug#3874).
1291 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1293 * buffer.h (BSET): Remove (Bug#12215).
1294 Replace all uses with calls to new setter functions.

1322 * category.c (bset_category_table):
1323 * syntax.c (bset_syntax_table):
1324 New setter functions.
1326 * process.h (PSET): Remove (Bug#12215).
1327 Replace all uses with calls to new setter functions.

1329 (PROCESS_INLINE): New macro.
1330 (pset_childp): New setter function.
1331 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
1332 * process.c (PROCESS_INLINE):
1333 Define to EXTERN_INLINE, so that the corresponding functions
1334 are compiled into code.
1335 (pset_buffer, pset_command, pset_decode_coding_system)

1338 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
1339 (pset_type, pset_write_queue): New setter functions.
1341 * window.h (WSET): Remove (Bug#12215).
1342 Replace all uses with calls to new setter functions.
1343 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1344 (WINDOW_INLINE): New macro.

1348 (wset_window_end_pos, wset_window_end_valid)
1349 (wset_window_end_vpos): New setter functions.

2121 value of EMACSLOADPATH, as it is no longer needed.
2122 (check_windows_init_file): Now external, not static.

2128 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2173 * alloc.c (record_xmalloc): New function.
2174 * lisp.h (record_xmalloc): New decl.
2175 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts

2177 needed. All uses changed.
2178 * print.c (print_string, print_error_message): Avoid length recalc.
2180 Improve fix for macroexp crash with debugging (Bug#12118).
2181 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

2185 (gc_aset): New function, which is like ASET but can be
2186 used in the garbage collector.

2215 with addition of handling of symlinks and support for 'lstat'.
2216 If possible, get file's attributes and security information by
2217 handle, not by name. Produce S_IFLNK bit for symlinks, when
2218 called from 'lstat'.
2219 (stat, lstat): New functions, call 'stat_worker'.
2220 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2221 symlinks when the underlying filesystem supports them.
2223 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2225 Fix macroexp crash on Windows with debugging (Bug#12118).
2226 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2227 checking subscripts; problem introduced with the recent
2228 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2229 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2230 since it's used in non-static inline functions now.

2696 (xd_close_bus, Fdbus_init_bus): Handle reference counter properly.
2698 2012-07-27 Eli Zaretskii <eliz@gnu.org>
2700 * alloc.c (listn): Fix the order the arguments are consed onto the
2703 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
2704 enumeration constants, as PURE and HEAP are too general, and clash
2705 with other headers and sources, such as gmalloc.c and the
2706 MS-Windows system headers. All users changed.
2708 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2710 Revert last save_excursion_save and save_excursion_restore changes.
2711 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

2721 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
2723 Improve GDB symbol export (Bug#12036).
2724 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
2725 arms of an 'if', not using conditional expressions; otherwise GDB
2726 complains about the types in the unevaluated arm when the argument
2727 is an integer literal.
2728 (xgetint): Simplify expression.
2729 * alloc.c (gdb_make_enums_visible): New constant. This ports to
2730 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
2731 Zaretskii in <http://bugs.gnu.org/12036#13>.
2732 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
2733 needed now that we have gdb_make_enums_visible.
2734 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
2735 (enum enum_USE_LSB_TAG):
2736 New enum types, packaging up enums that need to be exported to GDB.
2738 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2740 Utility function to make a list from specified amount of objects.

2754 * xdisp.c (syms_of_xdisp): Likewise.
2755 * xfns.c (syms_of_xfns): Likewise.
2757 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2759 Fast save_excursion_save and save_excursion_restore.
2760 * lisp.h (struct Lisp_Excursion): New data type.
2761 (PVEC_EXCURSION): New pseudovector type.
2762 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
2763 to deal with it. Adjust comments.
2764 (init_marker, attach_marker): New prototype.
2765 (unchain_marker): Adjust prototype.
2766 * marker.c (attach_marker): Change to global.

2774 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
2776 Fix export of symbols to GDB (Bug#12036).
2777 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
2778 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
2779 emacs.c, as this is a more-suitable home. Had this been done earlier
2780 the fix for 12036 would have avoided some of the problems noted in
2781 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
2782 would have been more obvious.
2783 * emacs.c: Do not include <verify.h>; no longer needed.
2784 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
2785 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
2786 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2787 Remove; now done in lisp.h.
2788 * lisp.h (PUBLISH_TO_GDB): New macro.
2789 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
2790 (DATA_SEG_BITS): Use it.
2791 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
2792 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
2793 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
2794 not be usable in #if. This simplifies things.
2796 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
2798 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
2800 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
2802 Simplify export of symbols to GDB (Bug#12036).
2803 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
2804 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
2805 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
2806 Adjust to changes in lisp.h and emacs.c, by using
2807 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
2808 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
2809 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
2810 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
2811 instead of gdb_valbits.
2812 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
2813 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
2814 instead of gdb_array_mark_flag.
2815 (xboolvector): Get size from $->size, not $->header.size.
2816 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
2817 (xreload, hook-run, hookpost-run): Remove.
2818 * emacs.c: Include <verify.h>.
2819 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
2820 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
2822 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
2823 (gdb_USE_LSB_TAG): New enum constants.
2824 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2825 Also define these as enum constants, so they're visible to GDB.
2826 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
2827 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
2828 as constants, so they're visible to GDB.
2829 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
2830 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
2831 Now enum constants, not macros, so they're visible to GDB.
2832 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
2833 more convenient now. All uses changed.
2834 (VALMASK) [USE_LSB_TAG]: Also define in this case.
2835 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
2837 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

2842 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
2844 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
2845 add argument, tune behavior, and adjust all callers.
2847 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
2849 Use typedef for EMACS_INT, EMACS_UINT.
2850 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
2851 than macros. This simplifies debugging in the usual case, since
2852 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
2853 and it allows expressions involving EMACS_INT casts.
2854 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
2856 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
2858 * nsterm.m (ns_read_socket): Return early if there is a modal

2864 that FOCUS-FRAME can be omitted.
2866 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
2868 Adjust buffer text indirection counters at the end of Fkill_buffer.
2869 * buffer.c (Fkill_buffer): Adjust indirection counters when the
2870 buffer is definitely dead. This should really fix an issue reported
2871 by Christoph Scholtes again. (Bug#12007).
2872 (init_buffer_once): Initialize indirection counters of
2873 buffer_defaults and buffer_local_symbols (for sanity and safety).
2875 2012-07-24 Eli Zaretskii <eliz@gnu.org>
2877 * xdisp.c (init_iterator): Don't compute dimensions of truncation
2878 and continuation glyphs on tooltip frames, leave them at zero.
2879 Avoids continued lines in tooltips. (Bug#11832)
2881 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
2883 Simplify copy_overlay.
2884 * buffer.c (copy_overlay): Simplify. Use build_marker.

2890 or invalid. (Bug#12025)
2892 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
2893 it signals an error when a tooltip frame is being created.
2895 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
2897 Cleanup miscellaneous objects allocation and initialization.

2904 (build_overlay): Add prototype.
2906 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
2908 Swap buffer text indirection counters in Fbuffer_swap_text.
2909 * buffer.c (Fbuffer_swap_text): Swap indirections too.
2910 This avoids crash reported by Christoph Scholtes at
2911 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
2913 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
2915 * nsmenu.m (Popdown_data): New struct.
2916 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
2918 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
2919 (initWithContentRect): Make imgView and contentView non-static
2920 and autorelease them. Also autorelease img and matrix (Bug#12005).
2921 (dealloc): Remove (Bug#12005).
2923 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
2925 Adjust consing_since_gc when objects are explicitly freed.
2926 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
2927 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
2928 (free_cons, free_misc): Subtract object size from consing_since_gc.
2930 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

2934 (live_buffer, set_marker_internal): New function.
2935 (Fset_marker, set_marker_restricted): Use set_marker_internal.

2938 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
2940 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
2941 as it's limited by the amount of memory, not by INT_MAX.
2943 2012-07-21 Eli Zaretskii <eliz@gnu.org>
2945 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
2946 in special-event-map. See the discussion at
2947 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
2950 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
2951 info.dwItemData. Fixes crashes on 64-bit Windows.

3005 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
3006 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
3007 Adjust users accordingly.
3008 * font.h (font_open_by_name): Adjust prototype.
3010 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

3019 * bytecode.c (MAYBE_GC): Use maybe_gc.
3020 * eval.c (eval_sub, Ffuncall): Likewise.

3022 to avoid dependency from auto-save feature.
3024 2012-07-19 Paul Eggert <eggert@cs.ucla.edu>
3026 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
3027 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3028 'for_each_per_buffer_object_at'.
3029 All uses changed. It's better to use upper-case for macros that
3030 cannot be implemented as functions, to give the reader a clue
3031 that they're special.
3033 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
3035 * alloc.c (Fgarbage_collect): Tweak docstring.

3075 Fix bug that created negative-length intervals.
3076 * intervals.c (merge_interval_right, merge_interval_left):
3077 Do not zero out this interval if it is absorbed by its children,
3078 as this interval's total length doesn't change in that case. See
3079 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3081 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3083 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3084 when invoking (make-bool-vector N t) and N is a positive
3085 multiple of 8 -- the last 8 bits were mistakenly cleared.
3087 Remove some struct layout assumptions in bool vectors.
3088 * alloc.c (bool_header_size): New constant.
3089 (header_size, word_size): Move earlier, as they're now used earlier.
3090 Use 'word_size' in a few more places, where it's appropriate.
3091 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
3092 padding before the data member of a bool vector.
3093 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3094 than doing the check by hand with an abort ().
3096 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3098 * eval.c (Fdefvar): Don't check constants since we only set the var if
3099 it's not yet defined anyway (bug#11904).
3101 * lisp.h (last_undo_boundary): Declare new var.
3102 * keyboard.c (command_loop_1): Set it.
3103 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3104 were auto-added by the command loop (bug#11774).
3106 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3108 * w32font.c (Qsymbol): Remove local definition.

3597 2012-07-11 Glenn Morris <rgm@gnu.org>
3599 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
3600 since nothing has defined it on these platforms.
3602 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
3603 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

3607 Move CLASH_DETECTION to configure.
3609 * s/gnu.h: Remove file, which is now empty.
3611 * s/gnu.h, s/gnu-linux.h:
3612 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
3614 2012-07-11 John Wiegley <johnw@newartisans.com>
3616 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
3617 function attribute, so we only use it if it exists in the
3620 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
3622 Avoid call to strlen in fast_c_string_match_ignore_case.
3623 * search.c (fast_c_string_match_ignore_case): Change to use
3624 length argument. Adjust users accordingly.
3625 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
3627 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>
3629 Assume mkdir, rmdir.

3668 Remove "#define unix" that is no longer needed (Bug#11905).
3669 * s/aix4-2.h (unix): Remove; no longer needed.
3671 EMACS_TIME simplification (Bug#11875).
3672 This replaces macros (which typically do not work in GDB)
3673 with functions, typedefs and enums, making the code easier to debug.
3674 The functional style also makes code easier to read and maintain.
3675 * systime.h: Include <sys/time.h> on all hosts, not just if
3676 WINDOWSNT, since 'struct timeval' is needed in general.
3677 (EMACS_TIME): Now a typedef, not a macro.
3678 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
3680 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

3683 (EMACS_TIME_LE): Now functions, not macros.
3684 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
3685 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
3686 which are not functions. All uses rewritten to use:
3687 (make_emacs_time): New function.
3688 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
3689 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
3690 not functions. All uses rewritten to use the following, respectively:
3691 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
3692 (add_emacs_time, sub_emacs_time): New functions.
3693 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
3694 * fileio.c (Fcopy_file):
3695 * xterm.c (XTflash): Get the current time closer to when it's used.
3696 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

3704 * gtkutil.c (get_utf8_string):
3706 * nsmenu.m (ns_update_menubar):
3707 * regex.c (regerror):
3708 Prefer memcpy to strncpy and strncat when either will do.
3709 * fileio.c (Fsubstitute_in_file_name):
3710 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
3711 (menu_separator_name_p):
3712 * nsmenu.m (ns_update_menubar):
3713 Prefer memcmp to strncmp when either will do.
3714 * nsterm.m: Include <ftoastr.h>.
3716 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
3717 Prefer snprintf to strncpy.
3718 * nsterm.m (ns_term_init):
3719 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
3720 * nsterm.m (ns_term_init):
3721 Avoid the need for strncpy, by using build_string or
3722 make_unibyte_string directly. Use dtoastr, not snprintf.
3723 * process.c (Fmake_network_process): Diagnose service names that
3724 are too long, rather than silently truncating them or creating
3725 non-null-terminated names.
3726 (Fnetwork_interface_info): Likewise, for interface names.
3727 * sysdep.c (system_process_attributes) [GNU_LINUX]:
3728 Prefer sprintf to strncat.
3729 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
3730 Prefer vsnprintf to vsprintf + strncpy.
3732 2012-07-10 Glenn Morris <rgm@gnu.org>
3734 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
3735 Clarify fallback case.
3737 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3739 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
3740 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
3741 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
3742 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
3743 where argument type is known to be a Lisp_Cons.
3745 2012-07-10 Tom Tromey <tromey@redhat.com>
3747 * bytecode.c (BYTE_CODE_THREADED): New macro.
3748 (BYTE_CODES): New macro. Replaces all old byte-code defines.

3755 Optimize pure C strings initialization.
3756 * lisp.h (make_pure_string): Fix prototype.
3757 (build_pure_c_string): New function, defined as static inline. This
3758 provides a better opportunity to optimize away calls to strlen when
3759 the function is called with compile-time constant argument.
3760 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
3761 argument, adjust users accordingly. Use build_pure_c_string where
3763 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
3764 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
3765 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
3767 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3769 Avoid calls to strlen in miscellaneous functions.
3770 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
3771 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
3772 * lread.c (openp): Likewise.
3774 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3776 Avoid calls to strlen in path processing functions.
3777 * fileio.c (file_name_as_directory): Add comment. Change to add
3778 srclen argument and return the length of result. Adjust users
3780 (directory_file_name): Fix comment. Change to add srclen argument,

3782 Adjust users accordingly.
3783 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
3785 2012-07-10 Glenn Morris <rgm@gnu.org>
3787 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

3790 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
3791 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
3792 * s/gnu.h (DATA_START): Move definitions to configure.
3794 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
3795 We include usg5-4-common.h, which defines them both.
3797 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
3798 O_RDONLY already includes it).
3800 Stop ns builds setting the EMACSLOADPATH environment variable.
3801 * nsterm.m (ns_load_path): Rename from ns_init_paths.
3802 Now it does not set EMACSLOADPATH, just returns the load-path string.
3803 * nsterm.h: Update accordingly.
3804 * lread.c [HAVE_NS]: Include nsterm.h.
3805 (init_lread) [HAVE_NS]: Use ns_load_path.
3806 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
3808 2012-07-09 Glenn Morris <rgm@gnu.org>
3810 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
3811 since the included bsd-common.h does so.
3813 Stop ns builds setting the EMACSPATH environment variable.
3814 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
3815 (ns_init_paths): Do not set EMACSPATH.
3816 * nsterm.h (ns_exec_path): Add it.
3817 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
3820 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
3822 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
3824 * process.c (wait_reading_process_output): 'waitchannels' was unset
3825 when read_kbd || !NILP (wait_for_cell); fix this.
3827 Add GCC-style 'const' attribute to functions that can use it.
3828 * character.h (char_resolve_modifier_mask):
3829 * keyboard.h (make_ctrl_char):
3830 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
3831 (init_character_once, next_almost_prime, init_fns, init_image)
3832 (flush_pending_output, init_sound):
3833 * mem-limits.h (start_of_data):

3837 Declare the dummy function with ATTRIBUTE_CONST.
3838 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
3839 Add decls with ATTRIBUTE_CONST.
3841 Minor improvements to make_formatted_string.
3842 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
3843 where int is good enough, as vsprintf returns an int.
3844 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
3846 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3848 Use make_formatted_string to avoid double length calculation.
3849 * lisp.h (make_formatted_string): New prototype.
3850 * alloc.c (make_formatted_string): New function.
3851 * buffer.c (Fgenerate_new_buffer_name): Use it.
3852 * dbus.c (syms_of_dbusbind): Likewise.

3854 * filelock.c (get_boot_time): Likewise.
3855 * frame.c (make_terminal_frame, set_term_frame_name)
3856 (x_report_frame_params): Likewise.
3857 * image.c (gs_load): Likewise.
3858 * minibuf.c (get_minibuffer): Likewise.

3873 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3875 Move marker debugging code under MARKER_DEBUG.
3876 * marker.c (MARKER_DEBUG): Move marker debugging code under
3877 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
3878 for bootstrap with --enable-checking (~3x slowdown reported
3879 by Juanma Barranquero <lekktu@gmail.com>).
3880 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
3882 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
3884 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
3885 See <http://bugs.gnu.org/11825#29>.
3887 2012-07-08 Eli Zaretskii <eliz@gnu.org>
3889 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
3890 has no font, use the frame's font. (Bug#11813)
3891 (display_line): Add commentary about displaying truncation glyphs
3893 (produce_special_glyphs): Move here from term.c.
3895 * term.c (produce_special_glyphs): Move to xdisp.c.
3897 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
3900 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
3902 * xdisp.c (display_line): Avoid warning about implicit declaration
3905 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
3907 * lisp.h: Remove empty conditional.
3909 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3911 * lread.c (load_path_check): Now static.
3913 Fix some minor --with-ns problems found by static checking.
3914 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
3915 (x_set_font) [!HAVE_X_WINDOWS]:
3916 * image.c (xpm_load_image) [HAVE_NS]:
3917 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
3918 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
3919 Remove unused local.
3920 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
3921 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
3922 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
3923 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
3924 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
3925 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
3926 Fix pointer signedness problem.
3927 * xfaces.c (FRAME_X_FONT_TABLE):
3928 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
3930 2012-07-07 Glenn Morris <rgm@gnu.org>
3932 * lread.c (load_path_check): New function, split from init_lread.
3933 (init_lread): Reorganize. Motivation:
3934 If EMACSLOADPATH is set, check/warn about that rather than the
3935 defaults, which we are not going to use. Hence we can remove
3936 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
3937 Don't warn if site-lisp directories are missing.
3938 If not installed, start from a blank load-path, since
3939 PATH_LOADSEARCH refers to the eventual installation directories.
3941 2012-07-07 Eli Zaretskii <eliz@gnu.org>
3943 Support truncation and continuation glyphs on GUI frames, when
3944 fringes are disabled. (Bug#11832)
3945 * xdisp.c (init_iterator): Get dimensions of truncation and
3946 continuation glyphs even if on GUI frames.
3947 Adjust it->last_visible_x on GUI frames when the left or right fringes,
3948 or both, are absent.
3949 (start_display, move_it_in_display_line_to): Handle the case of a
3950 GUI frame without a fringe to display continuation or truncation
3952 (insert_left_trunc_glyphs): Support GUI frames: make sure
3953 truncation glyphs overwrite enough glyphs from the current line to
3954 have sufficient space in pixels.
3955 (display_line): Support truncation and continuation glyphs on GUI
3956 frames. If some spare pixels are left on the line after inserting
3957 the truncation glyphs, fill that space with a stretch glyph of a
3958 suitably computed width.
3960 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
3961 produce_glyphs, to support GUI sessions.
3963 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3965 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
3967 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
3969 Do not require float-time's arg to fit in time_t (Bug#11825).
3970 This works better on hosts where time_t is unsigned, and where
3971 float-time is applied to the (negative) difference between two times.
3972 * editfns.c (decode_time_components): Last arg is now double *,
3973 not int *, and means to store all the result as a double, without
3974 worrying about whether the seconds part fits in time_t.
3975 All callers changed.
3976 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
3977 All callers changed.
3978 (Ffloat_time): Do not fail merely because the specified time falls
3979 outside of time_t range.
3981 2012-07-07 Glenn Morris <rgm@gnu.org>
3983 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

3987 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
3989 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
3990 Update dependencies.
3992 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
3994 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3996 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
3997 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
3998 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3999 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4000 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4001 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4003 * xfont.c (compare_font_names): Redo to omit the need for casts.
4005 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4007 * xfns.c (Fx_change_window_property): Doc fix.
4008 * w32fns.c (Fx_change_window_property): Doc fix.
4010 * w32fns.c (Fx_window_property): Accept the same arguments as the
4011 X Windows version. Doc fix.
4012 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4014 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4015 Eli Zaretskii <eliz@gnu.org>
4017 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4018 Windows-specific code from nt/config.nt moved here.
4019 Obsolete settings removed.
4021 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4023 * process.c: Avoid unnecessary calls to gettime.
4024 (wait_reading_process_output): Don't get the time of day
4025 when gobbling data immediately and not waiting, as there's no need
4026 for it in that case. This removes a FIXME.
4028 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4030 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4031 is defined (Bug#11768).

4035 Fix marker debugging code.
4036 * marker.c (byte_char_debug_check): Do not perform the check
4037 if buffer is not multibyte.
4038 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4039 Call byte_char_debug_check with correct arguments.
4041 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4043 Compile marker debugging code only if ENABLE_CHECKING is defined.
4044 * marker.c (byte_char_debug_check, count_markers):
4045 Use only if ENABLE_CHECKING is defined.
4046 (byte_debug_flag): Remove.
4047 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4048 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4050 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4052 Avoid code repetition in marker-related functions.
4053 * marker.c (attach_marker): New function.

4056 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4057 Consistently rename charno to charpos.
4058 (marker_position): Add eassert.
4059 (marker_byte_position): Convert to eassert.
4061 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

4071 * lisp.h (build_marker): New prototype.
4072 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4073 * composite.c (autocmp_chars): Likewise.
4074 * editfns.c (buildmark): Remove.
4075 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4076 (save_restriction_save): Use build_marker.
4077 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4078 * window.c (save_window_save): Likewise.
4080 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

4083 to avoid redundant calls to unchain_overlay.
4084 * buffer.c (drop_overlay): New function.
4085 (delete_all_overlays, Fdelete_overlay): Use it.
4086 * minibuf.c (get_minibuffer): Fix comment.
4088 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4090 Port to OpenBSD 5.1 amd64.
4091 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4092 This is needed for OpenBSD, and should be harmless on all BSD systems.
4093 Also, include <sys/sysctl.h>, as it should be available on all
4094 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4095 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4096 use p_pid member, not kp_proc.pid.
4098 2012-07-06 Glenn Morris <rgm@gnu.org>
4100 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4102 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4104 More xmalloc and related cleanup.
4105 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4113 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4115 Omit needless casts involving void * pointers and allocation.
4116 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4117 as the former is more robust if P's type is changed.
4118 Prefer xzalloc to xmalloc + memset 0.
4119 Simplify malloc-or-realloc to realloc.
4120 Don't worry about xmalloc returning a null pointer.
4121 Prefer xstrdup to xmalloc + strcpy.
4122 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4124 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4125 alloca of a constant.
4127 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4129 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4130 hscroll is larger than the line width. Fixes long and futile
4131 looping inside extend_face_to_end_of_line (on a TTY) producing
4132 glyphs that are not needed and thrown away.
4134 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4136 * marker.c (set_marker_restricted_both): Simplify by using
4139 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

4148 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4149 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4150 followed by gtk_box_set_homogeneous (Bug#11768).
4151 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4152 (update_theme_scrollbar_width, xg_create_scroll_bar):
4153 Use gtk_scrollbar_new (Bug#11768).
4154 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4155 (is_box_type): New function (Bug#11768).
4156 (xg_tool_item_stale_p): Call is_box_type.
4157 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4158 with default display (Bug#11768).

4162 * xdisp.c (window_hscroll_limited): New function.
4163 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4164 coordinates when window's hscroll is set to insanely large
4167 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4169 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

4230 * fileio.c (time_error_value): Check the right error number.
4231 Problem reported by Troels Nielsen in
4232 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

4236 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4237 This should be fixed in a better way; see Eli Zaretskii in
4238 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4239 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4241 * fileio.c (time_error_value): Rename from special_mtime.
4242 The old name's problems were noted by Eli Zaretskii in
4243 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4245 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4246 This variable's comment says Emacs needs at least one GDB-visible
4247 symbol of type enum pvec_type, to work around GDB problems.
4248 The symbol's value doesn't matter.
4250 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4251 that causes compilation to fail on pre-C99 compilers.
4253 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4255 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4256 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4258 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4260 * buffer.c (init_buffer_once): Fix initialization of
4261 headers for buffer_defaults and buffer_local_symbols.
4262 Reported by Juanma Barranquero <lekktu@gmail.com>.
4264 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4266 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4267 * lisp.h (enum pvec_type): Use fewer bits.
4268 (PSEUDOVECTOR_SIZE_BITS): New constant.
4269 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4270 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4271 change in pvec_type.
4272 (PSEUDOVECTOR_TYPEP): New macro.
4273 (TYPED_PSEUDOVECTORP): Use it.

4278 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4279 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4280 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4281 abusing vector->header.next.nbytes.
4282 (live_vector_p): Use PVEC_TYPE.
4283 (mark_object): Adapt code to extract pvectype. Use switch.
4285 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4287 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4288 Tighten new eassert a bit.
4290 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4292 Fix compilation with --enable-gcc-warnings and -O1
4294 * doprnt.c (doprnt): Change type of tem to int, initialize
4295 to avoid compiler warning. Add eassert.
4296 * search.c (simple_search): Initialize match_byte to avoid
4297 compiler warning. Add eassert.
4299 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4301 Avoid weird behavior with large horizontal scrolls.
4302 Without this change, for example, large hscroll values would
4303 mess up Emacs's display on Fedora 15 x86, presumably due to
4304 overflows in int calculations in the display code.
4305 Also, if buffers had long lines, Emacs would freeze.
4306 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4307 (set_window_hscroll): New function, containing the old guts of
4308 Fset_window_hscroll. Return the clipped value.
4309 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4310 This avoids the need to check against PTRDIFF_MAX.
4312 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4314 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4316 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4318 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4320 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4321 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4322 since GCC 4.4.6 issues a bogus warning for them.
4324 Fix bugs in file timestamp newness comparisons.
4325 * fileio.c (Ffile_newer_than_file_p):
4326 * lread.c (Fload): Use full timestamp resolution of files,
4327 not just the 1-second resolution, so that files that are only
4328 slightly newer still count as newer.
4329 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4330 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4332 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4334 * fileio.c: Improve handling of file time marker. (Bug#11852)
4335 (special_mtime): New function.
4336 (Finsert_file_contents, Fverify_visited_file_modtime):
4337 Use it to set special mtime values consistently.
4339 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4341 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4342 marker for non-existing file. (Bug#11852)
4344 2012-07-03 Glenn Morris <rgm@gnu.org>
4346 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4347 and did not make it into globals.h).
4349 2012-07-03 Tom Tromey <tromey@redhat.com>
4351 * window.c (Fset_window_margins, Fset_window_fringes)

4387 2012-07-03 Glenn Morris <rgm@gnu.org>
4389 * lisp.h (Frandom): Make it visible to C.
4390 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4391 buffer for invisible buffers. (Bug#1229)

4395 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4396 values which aren't power of 2.
4397 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4398 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4401 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4403 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

4407 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4409 * alloc.c (allocate_vector_block): Remove redundant
4410 calls to mallopt if DOUG_LEA_MALLOC is defined.
4411 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4412 avoid calls to mallopt if zero_vector is returned.
4414 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4416 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4417 is enabled, avoid dereferencing NULL current_sblock if
4420 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4422 Cleanup basic buffer management.
4423 * buffer.h (struct buffer): Change layout to use generic vector
4424 marking code. Fix some comments. Change type of 'clip_changed'
4425 to bitfield. Remove unused #ifndef old.
4426 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4427 (GET_OVERLAYS_AT): Fix indentation.

4432 * alloc.c (allocate_buffer): Adjust to match new layout of
4433 struct buffer. Fix comment.
4434 (mark_overlay): New function.

4436 Lisp area of struct buffer.
4437 (mark_object): Use it. Adjust marking of misc objects
4438 and related comments.
4440 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4442 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4443 wrapper that is not needed because the wrapped code is a no-op (zero
4444 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4445 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4447 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4449 * alloc.c (mark_buffer): Simplify. Remove prototype.
4450 (mark_object): Add comment. Reorganize marking of vector-like
4451 objects. Use CHECK_LIVE for all vector-like objects except buffers
4452 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4453 Avoid redundant calls to mark_vectorlike for bool vectors.
4455 2012-06-30 Glenn Morris <rgm@gnu.org>
4457 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4459 * epaths.in (PATH_SITELOADSEARCH): New.
4460 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4461 This is rather than relying on --enable-locallisppath elements
4462 having "site-lisp" in their names. (Bug#10208#25, 11658)
4464 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4466 * w32proc.c (sys_select): Accept and ignore one more argument.
4468 * w32.c (emacs_gnutls_pull): Call select with one more argument.

4475 * process.c (sys_select):
4476 * msdos.c (sys_select): Accept one more argument and ignore it.
4478 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4479 adapt data types and code to that.
4482 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4483 which clashes with the gnulib function of the same name.
4485 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4487 * font.c (font_style_to_value, font_style_symbolic)
4488 (font_prop_validate_style): Add type checks for values in
4491 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4493 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4496 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4498 * xdisp.c (try_window_id): Undo last change.
4500 * w32.c (getwd): Adjust commentary about startup_dir.
4501 (init_environment): Always call sys_access, even in non-MSVC
4502 builds. Don't chdir to the directory of the Emacs executable.
4503 This undoes code from 1997 which was justified by the need to
4504 "avoid conflicts when removing and renaming directories". But its
4505 downside was that every relative file name was being interpreted
4506 relative to the directory of the Emacs executable, which can never
4507 be TRT. In particular, it broke sys_access when called with
4508 relative file names.
4509 (sys_access): Map GetLastError to errno.
4511 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

4701 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
4703 Use sprintf return value instead of invoking strlen on result.
4704 In the old days this wasn't portable, since some sprintf
4705 implementations returned char *. But they died out years ago and
4706 Emacs already assumes sprintf returns int.
4707 Similarly for float_to_string.
4708 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

4716 Use sprintf or float_to_string result to avoid need to call strlen.
4717 * data.c (Fnumber_to_string):
4718 Use make_unibyte_string, since the string must be ASCII.
4719 * lisp.h, print.c (float_to_string): Now returns int length.
4720 * term.c (produce_glyphless_glyph):
4721 Use sprintf result rather than recomputing it.
4723 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
4724 * Makefile.in (ALL_CFLAGS):
4725 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

4756 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

4759 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
4761 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
4762 instead of truncating it to 63 (admittedly a generous limit).

4822 * keyboard.c (kbd_buffer_get_event):
4823 * process.c (Faccept_process_output):
4824 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
4825 This improves on the previous patch, which introduced a bug

4892 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
4894 Support higher-resolution time stamps (Bug#9000).
4895 The time stamps are only nanosecond-resolution at the C level,
4896 since that's the best that any real-world system supports now.
4897 But they are picosecond-resolution at the Lisp level, as that's
4898 easy, and leaves room for future OS improvements.
4900 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
4903 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
4904 Don't get current time unless it's needed.
4906 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
4907 now provides it if it's absent.
4908 (start_atimer): Port to higher-res time stamps.
4909 Check for time stamp overflow. Don't get current time more
4910 often than is needed.
4912 * buffer.h (struct buffer): Buffer modtime now has high resolution.
4913 Include systime.h, not time.h.
4914 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
4916 * dired.c: Include stat-time.h.
4917 (Ffile-attributes): File times now have higher resolution.
4919 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
4920 (struct image): Timestamp now has higher resolution.
4922 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
4923 has at least microseconds now. All uses removed.
4924 (update_frame, update_single_window, update_window, update_frame_1)
4925 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
4926 (duration_to_sec_usec): Remove; no longer needed.
4928 * editfns.c (time_overflow): Now extern.
4929 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
4930 (float-time, Fformat_time_string, Fcurrent_time_string)

4933 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
4934 (decode_time_components, lisp_seconds_argument): New functions.
4935 (make_time): Now static.
4936 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
4937 Report an error if the time is invalid, rather than having the caller
4940 * fileio.c: Include <stat-time.h>
4941 (Fcopy_file): Copy higher-resolution time stamps.
4942 Prefer to set the time stamp via a file descriptor if that works.
4943 (Fset_file_times, Finsert_file_contents, Fwrite_region)
4944 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
4945 (Fvisited_file_modtime, Fset_visited_file_modtime):
4946 Support higher-resolution time stamps.
4948 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
4950 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
4952 * image.c (prepare_image_for_display, clear_image_cache)
4953 (lookup_image): Port to higer-resolution time stamps.
4955 * keyboard.c (start_polling, bind_polling_period):
4956 Check for time stamp overflow.
4957 (read_char, kbd_buffer_get_event, timer_start_idle)
4958 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
4959 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
4960 Port to higher-resolution time stamps. Do not assume time_t is signed.
4961 (decode_timer): New function. Timers are now vectors of length 9,
4962 not 8, to accommodate the picosecond component.
4963 (timer_check_2): Use it.
4965 * nsterm.m (select_timeout, timeval_subtract): Remove.
4966 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
4967 as they're a bit more accurate and handle overflow better.
4968 (ns_select): Change prototype to be compatible with pselect.
4969 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
4970 * nsterm.h (ns_select): Adjust prototype.
4972 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
4973 us-resolution time stamps.
4974 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
4976 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
4978 * lisp.h (time_overflow): New decl.
4979 (wait_reading_process_output): First arg is now intmax_t, not int,
4980 to accommodate larger waits.
4982 * process.h (struct Lisp_Process.read_output_delay):
4983 Now counts nanoseconds, not microseconds.
4984 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
4986 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
4987 (wait_reading_process_output):
4988 Port to ns-resolution time stamps.
4989 (Faccept_process_output, wait_reading_process_output):
4990 Check for time stamp overflow. Do not assume time_t is signed.
4991 (select_wrapper): Remove; we now use pselect.
4992 (Fprocess_attributes): Now generates ns-resolution time stamps.
4994 * sysdep.c: Include utimens.h. Don't include utime.h
4995 or worry about struct utimbuf; gnulib does that for us now.
4996 (gettimeofday): Remove; gnulib provides a substitute.
4997 (make_timeval): New function.
4998 (set_file_times): Now sets ns-resolution time stamps.
4999 New arg FD; all uses changed.
5000 (time_from_jiffies, ltime_from_jiffies, get_up_time)

5002 Now returns ns-resolution time stamp. All uses changed.
5003 Check for time stamp overflow.
5005 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5006 provides a substitute now.
5008 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5009 since it guarantees struct timespec.
5010 (EMACS_TIME): Now struct timespec, so that we can support
5011 ns-resolution time stamps.
5012 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5013 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5014 (EMACS_USECS): Remove.
5015 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5016 so multiply the arg by 1000 before storing it.
5017 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5019 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5026 (make_timeval, make_lisp_time, decode_time_components): New decls.
5027 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5028 that it mishandled time_t overflow. You can't compare by subtracting!
5029 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5030 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

5040 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5041 (w32_get_internal_run_time):
5042 Port to higher-resolution Emacs time stamps.
5043 (ltime): Now accepts single 64-bit integer, as that's more convenient

5048 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5049 for compatibility with pselect. Support ns-resolution time stamps.

5053 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5054 Check for time stamp overflow, and support ns-resolution time stamps.
5056 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5057 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5058 (timeval_subtract): Remove; no longer needed.
5059 (XTflash, XTring_bell, x_wait_for_event):
5060 Port to ns-resolution time stamps. Don't assume time_t is signed.

5066 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5068 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5069 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5070 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5071 staticidx goes up to 1597 out of 1600 = 0x640.)
5073 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
5075 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5076 Otherwise, the umask might be mistakenly 0 while handling input signals.

5086 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
5087 access to `contents' member of Lisp_Vector objects with AREF and ASET
5090 2012-06-19 Chong Yidong <cyd@gnu.org>
5092 * frame.c (delete_frame): When selecting a frame on a different
5093 text terminal, do not alter the terminal's top-frame.

5097 (unwind_format_mode_line): Restore them.
5098 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
5100 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
5101 since tty frames can be explicitly named.
5102 (prepare_menu_bars): Likewise.
5104 * term.c (Ftty_top_frame): New function.
5106 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

5109 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
5110 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
5111 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
5112 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

5121 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
5122 gets killed during executing of this function (Bug#11665).
5123 Try to always return Qt when the buffer has been actually killed.
5124 (Vkill_buffer_query_functions): In doc-string say that functions
5125 run by this hook should not change the current buffer.
5127 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
5129 Fix recently-introduced process.c problems found by static checking.
5130 * process.c (write_queue_push, write_queue_pop, send_process):

5149 * lisp.h (eassert): Assume C89 or later.
5150 This removes the need for CHECK.
5151 (CHECK): Remove. Its comments about always evaluating its
5152 argument were confusing, as 'eassert' typically does not evaluate
5155 * coding.c (produce_chars): Use ptrdiff_t, not int.
5157 * xterm.c (x_draw_underwave): Check for integer overflow.
5158 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5456 2012-06-08 Eli Zaretskii <eliz@gnu.org>
5458 * alloc.c (allocate_vectorlike): Fix last change.
5460 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
5462 Block-based vector allocation of small vectors.
5463 * lisp.h (struct vectorlike_header): New field `nbytes',
5464 adjust comment accordingly.
5465 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
5466 to denote vector blocks. Adjust users (live_vector_p,
5467 mark_maybe_pointer, valid_lisp_object_p) accordingly.
5468 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
5469 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
5470 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
5471 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
5472 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
5473 (roundup_size): New constant.
5474 (struct vector_block): New data type.
5475 (vector_blocks, vector_free_lists, zero_vector): New variables.

5478 (sweep_vectors): New functions.
5479 (allocate_vectorlike): Return `zero_vector' as the only vector of
5480 0 items. Allocate new vector from block if vector size is less than

5482 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
5483 (init_alloc_once): Add call to init_vectors.

5487 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
5489 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
5491 * doprnt.c (doprnt): Truncate multibyte char correctly.
5492 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5493 would mishandle a string argument "Xc" if X was a multibyte
5494 character of length 2: it would truncate after X's first byte
5495 rather than including all of X.
5497 2012-06-06 Chong Yidong <cyd@gnu.org>
5499 * buffer.c (word_wrap): Doc fix.
5501 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

5524 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5525 (note_mode_line_or_margin_highlight): If there is no help echo,
5526 use mode-line-default-help-echo. Handle the case where the mouse
5527 position is past the end of the mode line string.
5529 * buffer.c (buffer_local_value_1): New function, split from
5530 Fbuffer_local_value; can return Qunbound.
5531 (Fbuffer_local_value): Use it.

5541 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5542 and DEFVAR it. Update all users.

5546 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5548 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5549 Convert pctcpu and pctmem to Lisp float properly.
5550 Let the compiler fold better, as 100.0/0x8000 is exact.
5552 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5554 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5557 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5559 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5561 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5563 For a 'struct window', replace some Lisp_Object fields to
5564 bitfields where appropriate, remove unused fields.
5565 * window.h (struct window): Remove unused 'last_mark_x' and
5566 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5567 change it's type from Lisp_Object to bitfield.
5568 Change type of 'force_start', 'optional_new_start',
5569 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5570 fields from Lisp_Object to bitfield. Adjust users accordingly.
5572 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5574 Pacify gcc -Wdouble-precision when using Xaw.
5575 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5576 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5577 Use 'float' consistently, rather than 'float' in most places
5578 and 'double' in a couple of places.
5580 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5582 * xdisp.c (handle_stop): Detect whether we have overlay strings
5583 loaded by testing it->current.overlay_string_index to be
5584 non-negative, instead of checking whether n_overlay_strings is
5585 positive. (Bug#11587)
5587 2012-05-31 Chong Yidong <cyd@gnu.org>
5589 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5591 * doc.c (Fsubstitute_command_keys): Doc fix.
5593 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5595 * search.c (search_buffer): Remove calls to
5596 r_alloc_inhibit_buffer_relocation, as it is now called by
5597 maybe_unify_char, which was the cause of relocation of buffer text
5600 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5602 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5603 for the duration of call to load_charset, to avoid problems with
5604 callers of maybe_unify_char that access buffer text through C
5607 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5608 decrement the inhibition flag, instead of just setting or
5611 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5613 Remove obsolete '#define static' cruft.
5614 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5615 This #undef was "temporary" in 2000; it is no longer needed
5616 now that '#define static' has gone away.
5617 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5618 (gray_bitmap_bits): Remove; no longer needed.
5619 All uses replaced with definiens.
5620 * xterm.c: Include "bitmaps/gray.xbm".
5622 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5624 Clean up __executable_start, monstartup when --enable-profiling.
5625 The following changes affect the code only when profiling.
5626 * dispnew.c (__executable_start): Rename from safe_bcopy.
5627 Define only on platforms that need it.
5628 * emacs.c: Include <sys/gmon.h> when profiling.
5629 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5630 (__executable_start): Remove decl, since lisp.h does it now.
5631 (safe_bcopy): Remove decl; no longer has that name.
5632 (main): Coalesce #if into single bit of code, for simplicity.
5633 Cast pointers to uintptr_t, since standard libraries want integers
5635 * lisp.h (__executable_start): New decl.
5637 2012-05-31 Glenn Morris <rgm@gnu.org>
5639 * image.c (Fimagemagick_types): Doc fix.

5658 * lread.c (read1): Tiny simplification.
5660 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
5662 Do not create empty overlays with the evaporate property (Bug#9642).
5663 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
5664 Bug#9642, but explicitly check that the buffer the overlay would
5665 be moved to is live and rearrange lines to make sure that errors
5666 will not put the overlay in an inconsistent state.
5667 (Fdelete_overlay): Cosmetics.
5669 2012-05-28 Eli Zaretskii <eliz@gnu.org>
5671 * w32term.c (my_bring_window_to_top): New function.
5672 (x_raise_frame): Use handle returned by DeferWindowPos, which
5673 could be different from the original one.
5674 Call my_bring_window_to_top instead of my_set_foreground_window.
5677 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
5678 by calling BringWindowToTop.
5680 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
5681 (WM_EMACS_END): Increase by one.
5683 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
5685 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
5686 This avoids undefined behavior that might cause the eassert
5687 to not catch an out-of-range value.
5689 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
5691 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

5701 when referring to sectname field in printf format.
5703 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
5705 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
5706 Only r_alloc_inhibit_buffer_relocation needed to be added;
5707 the others were already declared.
5709 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
5710 before checking whether it's out of range. Put the check inside
5712 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
5714 2012-05-27 Ken Brown <kbrown@cornell.edu>
5716 * callproc.c (Fcall_process): Restore a line that was accidentally
5717 commented out in the 2011-02-13 change (bug#11547).
5719 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5721 * lisp.h [REL_ALLOC]: Add prototypes for external functions
5722 defined on ralloc.c.
5724 * buffer.c [REL_ALLOC]: Remove prototypes of
5725 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
5726 they are now on lisp.h.
5728 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
5730 * search.c (search_buffer): Use it to inhibit relocation of buffer
5731 text while re_search_2 is doing its job, because re_search_2 is
5732 passed C pointers to buffer text. (Bug#11519)
5734 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
5737 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
5738 state after an additional call to move_it_in_display_line_to, keep
5739 the values of it->max_ascent and it->max_descent found for the
5741 (pos_visible_p): Revert the comparison against bottom_y to what it
5742 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
5745 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5747 Fix coding-related core dumps with gcc -ftrapv.
5748 The code was computing A - B, where A and B are pointers, and B is
5749 random garbage. This can lead to core dumps on platforms that
5750 have special pointer registers, and it also leads to core dumps on
5751 x86-64 when compiled with gcc -ftrapv. The fix is to compute
5752 A - B only when B is initialized properly.
5753 * coding.c (coding_set_source, coding_set_destination): Return void.
5754 (coding_change_source, coding_change_destinations): New functions,
5755 with the old behaviors of coding_set_source and coding_set_destination.
5756 All callers that need an offset changed to use these new functions.
5758 2012-05-26 Glenn Morris <rgm@gnu.org>
5760 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
5762 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5764 Extend mouse support on W32 text-mode console.
5765 * xdisp.c (draw_row_with_mouse_face):
5766 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
5768 * w32console.c: Include window.h.
5769 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
5771 (initialize_w32_display): Initialize mouse-highlight data.
5773 * w32inevt.c: Include termchar.h and window.h.
5774 (do_mouse_event): Support mouse-autoselect-window. When the mouse
5775 moves, call note_mouse_highlight. If help_echo changed, call
5776 gen_help_event to produce help-echo message in the echo area.
5777 Call clear_mouse_face if mouse_face_hidden is set in the mouse
5780 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5782 * lread.c (read1): Simplify slightly to avoid an overflow warning
5783 with GCC 4.7.0 on x86-64.
5785 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5787 * bidi.c (bidi_mirror_char): Revert last change: an int is
5788 definitely wide enough here.
5790 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
5792 Fix integer width and related bugs (Bug#9874).

5802 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5803 (allocate_pseudovector):
5804 Use int, not EMACS_INT, where int is wide enough.
5805 (inhibit_garbage_collection, Fgarbage_collect):
5806 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5807 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
5808 int might not be wide enough.
5809 (bidi_cache_search, bidi_cache_find, bidi_init_it)

5812 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
5813 (bidi_level_of_next_char, bidi_move_to_visually_next):
5814 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5815 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
5816 (Fkill_buffer, Fset_buffer_major_mode)
5817 (advance_to_char_boundary, Fbuffer_swap_text)
5818 (Fset_buffer_multibyte, overlays_at, overlays_in)
5819 (overlay_touches_p, struct sortvec, record_overlay_string)
5820 (overlay_strings, recenter_overlay_lists)
5821 (adjust_overlays_for_insert, adjust_overlays_for_delete)
5822 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
5823 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
5824 (Foverlay_recenter, last_overlay_modification_hooks_used)
5825 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
5826 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5827 (validate_region): Omit unnecessary test for b <= e,
5828 since that's guaranteed by the previous test.
5829 (adjust_overlays_for_delete): Avoid pos + length overflow.
5830 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
5831 (report_overlay_modification):
5832 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5833 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
5834 Omit pointer cast, which isn't needed anyway, and doesn't work
5835 after the EMACS_INT -> ptrdiff_t change.
5836 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
5837 * buffer.h: Adjust decls to match defn changes elsewhere.
5838 (struct buffer_text, struct buffer):
5839 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5840 Use EMACS_INT, not int, where int might not be wide enough.
5841 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
5842 not int, to avoid needless 32-bit limit on 64-bit hosts.
5843 (exec_byte_code): Use tighter memory-full test, one that checks
5844 for alloca overflow. Don't compute the address of the object just
5845 before an array, as that's not portable. Use EMACS_INT, not
5846 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
5847 * callint.c (Fcall_interactively):
5848 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5849 * callproc.c (call_process_kill, Fcall_process):
5850 Don't assume pid_t fits into an Emacs fixnum.
5851 (call_process_cleanup, Fcall_process, child_setup):
5852 Don't assume pid_t fits into int.
5853 (call_process_cleanup, Fcall_process, delete_temp_file)

5859 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
5860 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5861 (casify_object): Avoid integer overflow when overallocating buffer.
5862 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
5863 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
5864 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
5865 * category.h (CATEGORYP): Don't assume arg is nonnegative.
5866 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
5867 integers are now checked earlier. All uses replaced with XINT.
5869 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5870 For CCL_MapSingle, check that content and value are in int range.

5872 Check that Vcode_version_map_vector is a vector.
5873 (resolve_symbol_ccl_program): Check that vector header is in range.
5874 Always copy the vector, so that we can check its contents reliably
5875 now rather than having to recheck each instruction as it's being
5876 executed. Check that vector words fit in 'int'.
5877 (ccl_get_compiled_code, Fregister_ccl_program)
5878 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
5879 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
5880 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
5881 contents are in range.
5882 (Fccl_execute_on_string): Check that status is in range.
5883 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
5884 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
5885 Accept and return EMACS_INT, not int, because callers can pass values
5887 (c_string_width, strwidth, lisp_string_width, chars_in_text)
5888 (multibyte_chars_in_text, parse_str_as_multibyte)
5889 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)

5891 (string_escape_byte8, Fget_byte):
5892 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

5910 to be a character. Avoid int overflow if max_char is close

6605 * fileio.c, character.h: Minor style tweaks.
6607 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
6609 * window.h (clip_changed): Remove useless declaration.
6611 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
6613 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
6614 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
6616 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
6619 This directory predates autoconf and is no longer needed nowadays.
6620 Move its few remaining bits of functionality to where they're needed.
6621 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
6622 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

6624 * Makefile.in (M_FILE): Remove. All uses removed.
6625 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
6626 * lisp.h (USE_LSB_TAG):
6627 * mem-limits.h (EXCEEDS_LISP_PTR):
6628 Use VAL_MAX, not VALBITS, in #if.
6629 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
6630 (EMACS_UINT): Define unconditionally now.
6631 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
6632 (BITS_PER_EMACS_INT): New constants, replacing
6633 what used to be in config.h, but not useful in #if.
6634 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
6635 define them any more.
6636 (VAL_MAX): New macro.
6638 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
6639 BITS_PER_EMACS_INT, in #if.
6640 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
6641 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
6642 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
6643 * s/ms-w32.h (DATA_START):
6644 Move here from removed file m/intel386.h.
6645 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
6646 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
6648 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
6650 Assume C89 or later.
6651 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
6652 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
6654 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
6655 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
6656 * textprop.c, tparam.c (NULL): Remove.
6657 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
6658 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
6659 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
6660 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
6661 * xterm.c (input_signal_count): Assume volatile works.
6663 2012-05-21 Ken Brown <kbrown@cornell.edu>
6665 * xgselect.c (xg_select): Fix first argument in call to 'select'
6668 2012-05-20 Ken Brown <kbrown@cornell.edu>
6670 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
6671 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
6673 2012-05-19 Ken Brown <kbrown@cornell.edu>
6675 * xfns.c (x_in_use): Remove `static' qualifier.
6676 * xterm.h (x_in_use): Declare.
6677 * xgselect.c: Include xterm.h.
6678 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
6679 and `display_arg' (bug#9754).
6681 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
6683 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
6685 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
6686 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
6688 2012-05-18 Eli Zaretskii <eliz@gnu.org>
6690 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
6692 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
6693 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
6695 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
6696 reference to image_cache->refcount.
6697 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
6699 2012-05-17 Juri Linkov <juri@jurta.org>
6701 * search.c (Fword_search_regexp, Fword_search_backward)
6702 (Fword_search_forward, Fword_search_backward_lax)
6703 (Fword_search_forward_lax): Move functions to isearch.el
6704 (bug#10145, bug#11381).
6706 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
6708 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
6710 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
6712 * lread.c (init_obarray): Declare Qt and Qnil as special.
6714 2012-05-14 Glenn Morris <rgm@gnu.org>
6716 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
6717 Put "libexec" before "bin", for the sake of init_callproc_1.
6719 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6721 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
6723 * unexaix.c: Port to more-recent AIX compilers.
6724 (report_error, report_error_1, make_hdr, copy_sym)
6725 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
6726 Make arguments const char *, not char *, to avoid violations of C
6727 standard and to fix some AIX warnings reported by Gilles Pion.
6729 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6731 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
6732 already have overlays loaded.
6733 (handle_single_display_spec): Before returning without displaying
6734 fringe bitmap, synchronize the bidi iterator with the main display
6735 iterator, by calling iterate_out_of_display_property.
6736 (iterate_out_of_display_property): Detect buffer iteration by
6737 testing that it->string is a Lisp string.
6738 (get_next_display_element): When the current object is exhausted,
6739 and there's something on it->stack, call set_iterator_to_next to
6740 proceed with what's on the stack, instead of returning zero.
6741 (set_iterator_to_next): If called at the end of a Lisp string,
6742 proceed to consider_string_end without incrementing string
6743 position. Don't increment display vector index past the end of
6744 the display vector. (Bug#11417)
6745 (pos_visible_p): Don't report a position visible when move_it_to
6746 stopped at the last line of window, which happens to be scanned
6747 backwards by the bidi iteration. (Bug#11464)
6749 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6751 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
6752 and right-margin display specs even if the spec is invalid or we
6753 are on a TTY, and thus unable to display on the fringes.
6754 That's because the text with the property will not be displayed anyway,
6755 so we need to signal to the caller that this is a "replacing"
6756 display spec. This fixes display when the spec is invalid or we
6759 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6761 * unexaix.c (make_hdr): Fix typo in prototype.
6762 This bug broke the build on AIX. Problem reported by Gilles Pion.
6764 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
6766 * keyboard.c (kbd_buffer_get_event): Read special events also in
6767 batch mode. (Bug#11415)
6769 2012-05-12 Glenn Morris <rgm@gnu.org>
6771 * ns.mk: Update for ns_appbindir no longer having trailing "/".
6773 2012-05-12 Eli Zaretskii <eliz@gnu.org>
6775 * lisp.mk (lisp): Add newcomment.elc.
6777 2012-05-12 Glenn Morris <rgm@gnu.org>
6779 * Makefile.in (MKDIR_P): New, set by configure.
6780 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
6782 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
6784 Remove unused function hourglass_started.
6785 * dispextern.h (hourglass_started):
6786 * w32fns.c (hourglass_started):
6787 * xdisp.c (hourglass_started): Remove.
6789 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
6791 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
6792 Update dependencies.
6794 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
6796 * xgselect.c (xg_select): Put maxfds+1 into a var.
6797 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
6799 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
6801 2012-05-10 Dave Abrahams <dave@boostpro.com>
6803 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
6804 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
6806 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
6808 * dbusbind.c (xd_registered_buses): New internal Lisp object.
6809 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
6810 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
6811 Initialize xd_registered_buses.
6813 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
6815 Untag more efficiently if USE_LSB_TAG.
6816 This is based on a proposal by YAMAMOTO Mitsuharu in
6817 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
6818 For an admittedly artificial (nth 8000 longlist) benchmark on
6819 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
6820 Emacs's overall text size by 1%.
6821 * lisp.h (XUNTAG): New macro.
6822 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
6823 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
6824 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
6825 * eval.c (Fautoload):
6826 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
6827 * frame.h (XFRAME): Use XUNTAG.
6829 Port recent dbusbind.c changes to 32-bit --with-wide-int.
6830 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
6831 Remove unportable assumptions about print widths of types like
6833 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
6834 intptr_t when converting between pointer and integer, to avoid GCC
6835 warnings about wrong width.
6837 2012-05-09 Eli Zaretskii <eliz@gnu.org>
6839 * w32proc.c (new_child): Force Windows to reserve only 64KB of
6840 stack for each reader_thread, instead of defaulting to 8MB
6841 determined by the linker. This avoids failures in creating
6842 subprocesses on Windows 7, see the discussion in this thread:
6843 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
6845 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
6847 Fix up display of the *Minibuf-0* buffer in the mini window.
6848 * keyboard.c (read_char): Don't clear the echo area if there's no
6850 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
6851 contents of *Minibuf-0*) if there's no message displayed in its stead.
6853 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
6855 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
6858 2012-05-06 Chong Yidong <cyd@gnu.org>
6860 * lisp.mk (lisp): Update.
6862 2012-05-05 Jim Meyering <meyering@redhat.com>
6864 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
6866 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
6868 * data.c (PUT_ERROR): New macro.
6869 (syms_of_data): Use it. Add new error type `user-error'.
6870 * undo.c (user_error): New function.
6871 (Fprimitive_undo): Use it.
6872 * print.c (print_error_message): Adjust print style for `user-error'.
6873 * keyboard.c (user_error): New function.
6874 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
6876 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
6878 Do not limit current-time-string to years 1000..9999.
6879 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
6880 (Fcurrent_time_string): Support any year that is supported by the
6881 underlying localtime representation. Don't use asctime, as it
6882 has undefined behavior for years outside the range -999..9999.
6884 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
6886 Fix race conditions involving setenv, gmtime, localtime, asctime.
6887 Without this fix, interrupts could mess up code that uses these
6888 nonreentrant functions, since setting TZ invalidates existing
6889 tm_zone or tzname values, and since most of these functions return
6890 pointers to static storage.
6891 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
6892 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
6893 Grow the critical sections to include not just invoking
6894 localtime/gmtime, but also accessing these functions' results
6895 including their tm_zone values if any, and any related TZ setting.
6896 (format_time_string): Last arg is now struct tm *, not struct tm **,
6897 so that the struct tm is saved in the critical section.
6898 All callers changed. Simplify allocation of initial buffer, partly
6899 motivated by the fact that memory allocation needs to be outside
6900 the critical section.
6902 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
6904 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
6905 with RESET_INTERVAL.
6907 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
6908 Remove duplicated buffer name initialization.
6910 2012-05-02 Jim Meyering <jim@meyering.net>
6912 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
6914 * xfns.c (x_window): Use xstrdup (Bug#11375).
6916 2012-05-02 Eli Zaretskii <eliz@gnu.org>
6918 * xdisp.c (pos_visible_p): If already at a newline from the
6919 display string before the 'while' loop, don't walk back the glyphs
6920 from it3.glyph_row. Solves assertion violation when the display
6921 string begins with a newline (egg.el). (Bug#11367)
6923 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
6925 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
6928 2012-05-01 Glenn Morris <rgm@gnu.org>
6930 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
6931 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
6932 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
6933 All were removed before 23.1.
6935 * dispnew.c: Remove HAVE_LIBNCURSES test;
6936 it is always true on relevant platforms.
6938 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
6939 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
6941 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
6943 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
6945 * .gdbinit (xpr): Remove checks for no longer existing misc types.
6946 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
6949 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
6951 Do not avoid creating empty evaporating overlays (Bug#9642).
6952 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
6953 That is, do not delete an evaporating overlay if it becomes
6954 empty after its bounds are adjusted to fit within its buffer.
6955 This fix caused other problems, and I'm reverting it until we get
6956 to the bottom of them.
6958 2012-04-27 Chong Yidong <cyd@gnu.org>
6960 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
6962 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6964 * xdisp.c (pos_visible_p): If the window start position is beyond
6965 ZV, start the display from buffer beginning. Prevents assertion
6966 violation in init_iterator when the minibuffer window is scrolled
6969 * window.c (window_scroll_pixel_based): Likewise.
6971 2012-04-27 Chong Yidong <cyd@gnu.org>
6973 * keymap.c (where_is_internal): Doc fix (Bug#10872).
6975 2012-04-27 Glenn Morris <rgm@gnu.org>
6977 * fileio.c (Fcopy_file, Fset_file_selinux_context):
6978 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
6980 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6982 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
6983 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
6985 2012-04-26 Eli Zaretskii <eliz@gnu.org>
6987 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
6988 display element, check also the underlying string or buffer
6989 character. (Bug#11341)
6991 * w32menu.c: Include w32heap.h.
6992 (add_menu_item): If the call to AppendMenuW (via
6993 unicode_append_menu) fails, disable Unicode menus only if we are
6994 running on Windows 9X/Me.
6996 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6998 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6999 (xgetint): Add missing shift for LSB tags.
7001 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7003 * keyboard.c (read_char): Don't wipe echo area for select window
7004 events: These might get delayed via `mouse-autoselect-window'
7007 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7009 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7010 manipulation of :loaded-from data.
7012 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
7014 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7015 now a cons (bug#11311).
7017 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7019 Do not create empty overlays with the evaporate property (Bug#9642).
7020 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7021 if it becomes empty after its bounds are adjusted to fit within
7022 its buffer. Without this fix, in a nonempty buffer (let ((o
7023 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7024 yields an empty overlay that has the evaporate property, which is
7025 not supposed to happen.
7027 Fix minor GTK3 problems found by static checking.
7028 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7029 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7030 (struct _EmacsFixedClass, emacs_fixed_get_type):
7031 Move decls here from emacsgtkfixed.h, since they needn't be public.
7032 (emacs_fixed_get_type): Now static.
7033 (emacs_fixed_class_init): Omit unused local.
7034 (emacs_fixed_child_type): Remove; unused.
7035 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7036 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7037 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7038 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7039 (EMACS_FIXED_GET_CLASS): Remove; unused.
7040 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7042 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7043 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7045 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7047 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7048 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7049 (__malloc_size_t, __malloc_ptrdiff_t):
7050 Remove. All uses removed, replaced by the definiens if needed,
7051 since we can assume C89 or better now.
7052 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7053 (protect_malloc_state, align, get_contiguous_space)

7129 since the two debugging options are incompatible.
7130 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7132 (mem_init, mem_insert, mem_insert_fixup):
7133 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7299 2012-04-11 Daniel Colascione <dancol@dancol.org>
7301 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7302 against is gone. It's better to use vfork now so that when Cygwin
7303 gains a new, working vfork, we use it automatically (bug#10398).

7360 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7362 * xdisp.c (set_cursor_from_row): If the display string appears in
7363 the buffer at position that is closer to point than the position
7364 after the display string, display the cursor on the first glyph of
7365 the display string. Fixes cursor display when a 'display' text
7366 property immediately follows invisible text. (Bug#11094)
7368 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7370 composite.c: use 'double' consistently
7371 * composite.c (get_composition_id): Use 'double' consistently
7372 instead of converting 'float' to 'double' and vice versa; this is
7373 easier to understand and avoids a GCC warning.

7422 [!WINDOWSNT]: New macros.
7423 (init_libxml2_functions, libxml2_loaded_p): New functions.
7424 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7425 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.

7447 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7448 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7449 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7450 macros related to unification of CJK characters. For the details,
7451 see the discussion following the message here:
7452 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7454 2012-04-04 Chong Yidong <cyd@gnu.org>

7471 position we get to after a call to move_it_to fails the
7472 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7473 only if we wind up in a string from display property. (Bug#11063)
7475 * window.c (Fdelete_other_windows_internal): Invalidate the row
7476 and column information about mouse highlight, so that redisplay
7477 restores it after reallocating the glyph matrices. (Bug#7464)
7479 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7480 string comes from a `display' text property, use the buffer
7481 position of that property as if we actually saw that position in
7483 (move_it_by_lines): Remove the assertion that
7484 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7485 violated when there's a before-string at the beginning of a line.
7488 2012-03-30 Eli Zaretskii <eliz@gnu.org>

7518 (command_loop_1): Use it; inhibit selection update for
7519 handle-select-window too (Bug#8996).
7521 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7523 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
7525 2012-03-25 Kenichi Handa <handa@m17n.org>
7527 * dispextern.h (struct glyph): Change the bit length of
7528 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7530 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7532 * s/ms-w32.h (tzname): Include time.h before redirecting to
7533 _tzname. Fixes the MSVC build. (Bug#9960)

7537 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
7540 * xterm.c (XTread_socket): Only modify handling_signal if
7541 !SYNC_INPUT. (Bug#11080)
7543 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7545 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7546 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7547 when fetching a multibyte character consumes more bytes than
7548 CHAR_BYTES returns, due to unification of CJK characters in
7549 string_char. (Bug#11073)
7551 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7553 * process.c (wait_reading_process_output): Handle pty disconnect
7554 by refraining from sending oneself a SIGCHLD (bug#10933).
7556 2012-03-22 Chong Yidong <cyd@gnu.org>

7571 * w32proc.c (Fw32_set_console_codepage)
7572 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
7575 2012-03-20 Chong Yidong <cyd@gnu.org>
7577 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
7578 to reflect default non-nil value of redisplay-dont-pause.
7580 2012-03-19 Kenichi Handa <handa@m17n.org>
7582 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
7583 it fit in a valid range (Bug#11003).
7585 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7587 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7588 that is not from display property, accept the row as a "cursor
7589 row" if one of the string's character has a non-nil `cursor'
7590 property. Fixes cursor positioning when there are newlines in
7591 overlay strings, e.g. in icomplete.el. (Bug#11035)
7593 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
7595 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
7597 2012-03-12 Chong Yidong <cyd@gnu.org>
7599 * eval.c (inhibit_lisp_code): Rename from
7600 inhibit_window_configuration_change_hook; move from window.c.
7602 * xfns.c (unwind_create_frame_1, Fx_create_frame):
7603 * window.c (run_window_configuration_change_hook)
7604 (syms_of_window): Callers changed.
7606 2012-03-11 Chong Yidong <cyd@gnu.org>

7615 is visible (Bug#10955).
7617 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
7619 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
7621 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
7623 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
7624 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7627 2012-03-03 Glenn Morris <rgm@gnu.org>
7629 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
7631 2012-03-02 Eli Zaretskii <eliz@gnu.org>
7633 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
7634 position past the first glyph_row that ends at ZV. (Bug#10902)
7635 (redisplay_window, next_element_from_string): Fix typos in
7637 (redisplay_window): Pass to move_it_vertically the margin in
7638 pixels, not in screen lines.
7640 2012-03-02 Glenn Morris <rgm@gnu.org>
7642 * buffer.c (buffer-list-update-hook): Doc fix.
7644 2012-02-29 Eli Zaretskii <eliz@gnu.org>
7646 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
7647 push_it before setting up the iterator for the first overlay
7648 string, even if we have an empty string loaded.
7649 (next_overlay_string): If there's an empty string on the iterator
7650 stack, pop the stack. (Bug#10903)
7652 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
7654 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
7655 Suggested by Stefan Monnier in
7656 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
7657 * alloc.c (widen_to_Lisp_Object): New static function.
7658 (mark_memory): Also mark Lisp_Objects by fetching pointer words
7659 and widening them to Lisp_Objects. This would work even if
7660 USE_LSB_TAG is defined and wide integers are used, which might
7661 happen in a future version of Emacs.
7663 2012-02-25 Chong Yidong <cyd@gnu.org>
7665 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
7668 * xselect.c (Fx_selection_exists_p): Doc fix.
7669 (x_clipboard_manager_save_all): Print an informative message
7670 before saving to clipboard manager.
7672 2012-02-24 Chong Yidong <cyd@gnu.org>
7674 * keyboard.c (process_special_events): Handle all X selection
7675 requests in kbd_buffer, not just the next one (Bug#8869).
7677 2012-02-23 Chong Yidong <cyd@gnu.org>
7679 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
7680 call when setting menu-bar-lines and tool-bar-lines parameters.
7681 (unwind_create_frame_1): New helper function.
7683 * window.c (inhibit_window_configuration_change_hook): New var.
7684 (run_window_configuration_change_hook): Obey it.
7685 (syms_of_window): Initialize it.
7687 2012-02-22 Chong Yidong <cyd@gnu.org>
7689 * xterm.c (x_draw_image_relief): Add missing type check for
7690 Vtool_bar_button_margin (Bug#10743).

7694 * fileio.c (Vfile_name_handler_alist): Doc fix.
7696 * buffer.c (Fget_file_buffer): Protect against invalid file
7697 handler return value.
7699 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
7701 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
7702 when computing $valmask.
7704 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
7705 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
7706 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
7707 It's useless in that case, and it can cause problems on hosts
7708 that allocate halves of EMACS_INT values separately.
7709 Reported by Dan Horák. Diagnosed by Andreas Schwab in
7710 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
7711 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
7712 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
7713 it avoids undefined behavior on hosts where shifting right by more
7714 than the word width has undefined behavior.
7716 2012-02-19 Chong Yidong <cyd@gnu.org>
7718 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
7719 (Funhandled_file_name_directory, Ffile_name_as_directory)
7720 (Fdirectory_file_name, Fexpand_file_name)

7736 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
7738 2012-02-15 Chong Yidong <cyd@gnu.org>
7740 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
7741 marked as special. Also, starting docstrings with * is obsolete.
7743 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
7745 * gnutls.c (emacs_gnutls_write): Fix last change.
7747 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

7756 2012-02-12 Chong Yidong <cyd@gnu.org>
7758 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
7759 as that creates a dangerous corner case.
7761 * window.c (Fdelete_window_internal): Invalidate the mouse
7762 highlight (Bug#9904).
7764 2012-02-12 Glenn Morris <rgm@gnu.org>

7767 (Fx_get_selection_internal, Fx_disown_selection_internal)
7768 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
7769 * nsselect.m (Fx_own_selection_internal)
7770 (Fx_disown_selection_internal, Fx_selection_exists_p)
7771 (Fx_selection_owner_p, Fx_get_selection_internal):
7772 Sync docs and argument specs with the xselect.c versions.
7774 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
7776 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

7790 2012-02-09 Kenichi Handa <handa@m17n.org>
7792 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
7794 2012-02-07 Chong Yidong <cyd@gnu.org>
7796 * buffer.c (Fbuffer_local_variables)
7797 (buffer_lisp_local_variables): Handle unbound vars correctly;
7798 don't let Qunbound leak into Lisp.
7800 2012-02-07 Glenn Morris <rgm@gnu.org>
7802 * image.c (Fimagemagick_types): Doc fix.
7804 * image.c (imagemagick-render-type): Change it from a lisp object
7805 to an integer. Move the doc here from the lisp manual.

7808 2012-02-06 Chong Yidong <cyd@gnu.org>
7810 * doc.c (store_function_docstring): Avoid applying docstring of
7811 alias to base function (Bug#2603).
7813 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
7815 * .gdbinit (pp1, pv1): Remove redundant defines.
7818 2012-02-04 Chong Yidong <cyd@gnu.org>
7820 * nsterm.m: Declare a global (Bug#10694).
7822 2012-02-04 Eli Zaretskii <eliz@gnu.org>

7825 Include --enable-checking, if specified, in the return value.
7827 2012-02-04 Martin Rudalics <rudalics@gmx.at>
7829 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
7830 after rounding frame sizes. (Bug#9723)

7834 * keyboard.c (adjust_point_for_property): Don't position point
7835 before BEGV. (Bug#10696)
7837 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
7839 Handle overflow when computing char display width (Bug#9496).
7840 * character.c (char_width): Return EMACS_INT, not int.
7841 (char_width, c_string_width): Check for overflow when
7842 computing the width; this is possible now that individual
7843 characters can have unbounded width. Problem introduced
7844 by merge from Emacs 23 on 2012-01-19.
7846 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
7848 * dbusbind.c (Fdbus_register_method): Mention the return value

7861 2012-02-02 Kenichi Handa <handa@m17n.org>
7863 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
7864 0, do not call append_composite_glyph.

7868 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
7870 (x_produce_glyphs): If the component of a composition is a null
7871 string, set it->pixel_width to 1 to avoid zero-width glyph.
7873 2012-02-01 Eli Zaretskii <eliz@gnu.org>
7875 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
7876 first 2 arguments are identical. This makes inserting large
7877 output from a subprocess an order of magnitude faster on
7878 MS-Windows, where all sbrk'ed memory is always contiguous.
7880 2012-01-31 Glenn Morris <rgm@gnu.org>

7921 since nil is not allowed anyway.
7923 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
7925 * process.c (read_process_output): Use p instead of XPROCESS (proc).

7936 * character.c (char_width): New function.
7937 (Fchar_width, c_string_width, lisp_string_width):
7938 Use char_width (Bug#9496).

7942 * window.c (Vwindow_persistent_parameters): New variable.
7943 (Fset_window_configuration, save_window_save): Handle persistent
7946 2012-01-14 Eli Zaretskii <eliz@gnu.org>
7948 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
7949 thrashing the stack of the thread. (Bug#9087)

7960 he end column for display of highlight that ends on a newline
7963 2012-01-11 Glenn Morris <rgm@gnu.org>
7965 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
7966 from load-path also when installation-directory is nil. (Bug#10208)
7968 2012-01-10 Glenn Morris <rgm@gnu.org>
7970 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

7973 Update template values to be closer to their typical values these days.
7975 2012-01-09 Eli Zaretskii <eliz@gnu.org>
7977 * xdisp.c (rows_from_pos_range): Accept additional argument
7978 DISP_STRING, and accept any glyph in a row whose object is that
7979 string as eligible for mouse highlight. Fixes mouse highlight of
7980 display strings from overlays. (Bug#10464)
7982 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
7984 emacs: fix an auto-save permissions race condition (Bug#10400)
7985 * fileio.c (auto_saving_dir_umask): New static var.
7986 (Fmake_directory_internal): Use it.
7987 (do_auto_save_make_dir): Set it, instead of invoking chmod after
7988 creating the directory. The old code temporarily assigns
7989 too-generous permissions to the directory.
7990 (do_auto_save_eh): Clear it.
7991 (Fdo_auto_save): Catch all errors, not just file errors, so
7992 that the var is always cleared.
7994 2012-01-07 Eli Zaretskii <eliz@gnu.org>
7996 * search.c (scan_buffer): Pass character positions to
7997 know_region_cache, not byte positions. (Bug#6540)
7999 2012-01-07 LynX <_LynX@bk.ru> (tiny change)
8001 * w32.c (sys_rename): Report EXDEV when rename of a directory

8495 Problem reported by Andreas Schwab in
8496 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
8497 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
8498 is set, removing the need for VIRT_ADDRESS_VARIES.
8499 (PURE_P): Use a more-efficient implementation that needs just one
8500 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

8502 to 4 (xorl, subq, cmpq, setbe).
8503 * alloc.c (pure): Always extern now, since that's the

8506 consistency with the new puresize.h.
8507 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

8593 * xdisp.c (display_line): Move the call to

8772 (Fwindow_vscroll): Doc fix.

8983 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
8985 (w32font_open_internal, compute_metrics):
8986 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
8987 instead of calling the "wide" APIs directly.
8989 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
8991 * w32.h (syms_of_w32font): Add prototype.
8993 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
8995 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
8996 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
8997 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
8998 (Fmove_to_window_line): Doc fix.
9000 2011-10-27 Chong Yidong <cyd@gnu.org>
9002 * process.c (make_process): Set gnutls_state to NULL.
9004 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
9005 non-NULL, regardless of GNUTLS_INITSTAGE.
9006 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
9007 an error. Set process slots as soon as we allocate them.
9009 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9011 2011-10-27 Chong Yidong <cyd@gnu.org>
9013 * gnutls.c (emacs_gnutls_deinit): New function.
9014 Deallocate credentials structures as well as calling gnutls_deinit.
9015 (Fgnutls_deinit, Fgnutls_boot): Use it.
9017 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9018 (deactivate_process): Call emacs_gnutls_deinit.
9020 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9022 * image.c (x_create_x_image_and_pixmap):
9023 * w32.c (sys_rename, w32_delayed_load):
9024 * w32font.c (fill_in_logfont):
9025 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9027 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9029 * w32fns.c (w32_default_color_map): New function,
9030 extracted from Fw32_default_color_map.
9031 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9033 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9035 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9037 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9039 * keyboard.c (test_undefined): New function (bug#9751).
9040 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9042 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9044 * sysdep.c (init_sys_modes): Fix the check for the controlling
9045 terminal (Bug#6649).
9047 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9049 * dispextern.h (struct bidi_it): New member next_en_type.
9051 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9052 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9053 current character, check also for next_en_type being WEAK_EN.
9054 (bidi_resolve_weak): Don't enter the expensive loop if the current
9055 position is before next_en_pos. Record the bidi type of the first
9056 non-ET, non-BN character we find, in addition to its position.
9057 (bidi_level_of_next_char): Invalidate next_en_type when
9058 next_en_pos is over-stepped.
9060 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9062 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9063 * editfns.c: Rewrite current-time-zone so that it invokes
9064 the equivalent of (format-time-string "%Z") to get the time zone name.
9065 This fixes a bug when the time zone name contains characters that
9066 need converting from the system time locale to Emacs internal format.
9067 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9068 that patch fixed format-time-string to do the conversion, but
9069 I forgot to fix current-time-zone.
9070 (format_time_string): New function, containing most of
9071 what Fformat_time_string used to contain.
9072 (Fformat_time_string): Rewrite in terms of format_time_string.
9073 This doesn't change this function's behavior.
9074 (current-time-zone): Rewrite to use format_time_string.
9075 This fixes the bug reported by Michael Schierl in
9076 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9077 Jason Rumney's 2007-06-07 change worked around this bug, but
9079 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9081 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9083 * xdisp.c (start_display): If the character at POS is displayed
9084 via a display vector, reset IT->current.dpvec_index to zero.
9085 (try_window_reusing_current_matrix): If a line ends in a display
9086 vector or the next line starts in a display vector, continue
9087 redrawing the window even though the character position of
9088 start_row was reached.
9091 2011-10-18 Chong Yidong <cyd@gnu.org>
9093 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9094 with nobreak-char-display too.
9096 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9098 Fix part 3 of bug#9771.
9099 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9100 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9101 non-neutral characters if the current character is a paragraph
9102 separator (a.k.a. Newline). This avoids running the same
9103 expensive loop twice, once when we consume the preceding newline
9104 and the other time when the line actually needs to be displayed.
9105 Avoid the loop when we see neutrals on the base embedding level
9106 following a character whose directionality is the same as the
9107 paragraph's. This avoids running the expensive loop when a line
9108 ends in a long sequence of neutrals, like control characters.
9109 Add assertion against STRONG_AL type. Slightly rearrange code
9110 that determines the type of a neutral given the first non-neutral
9112 (bidi_level_of_next_char): Set next_en_pos to zero when
9113 invalidating its info.
9115 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9117 * xdisp.c (push_display_prop): Determine whether to record string
9118 or buffer position by IT->string, not by IT->method. Allow
9119 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9120 (move_it_vertically_backward): Don't look for character position
9121 immediately after the newline when in a continuation line.
9124 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9126 * window.c (coordinates_in_window): Rewrite and delabelize
9127 vertical border check. (Bug#5357) (Bug#9618)
9129 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9131 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9132 errors in XSetWindowBorder (bug#9310).
9134 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9136 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9137 avoid crash when xmalloc overrun checking is enabled.
9139 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9141 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9142 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9143 cursor motion with <left> and <right> arrow keys.
9145 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9146 some callers set that themselves.
9148 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9150 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9151 display string and the previous row comes from the same string and
9152 is empty. (Bug#9739) (Bug#9738)
9154 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9156 * doc.c (get_doc_string): Encode file name (bug#9735).
9158 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9160 * bidi.c (bidi_level_of_next_char):
9161 * xdisp.c (get_visually_first_element): Remove old incorrect
9162 comments regarding the Unicode Line Separator character.
9164 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9166 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9168 * alloc.c (Fgc_status): Do not access beyond zombies array
9169 boundary if nzombies > MAX_ZOMBIES.
9170 * alloc.c (dump_zombies): Add missing format specifier.
9172 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9174 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9175 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9177 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9178 Some packages use them to denote characters with modifiers.
9180 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9182 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9183 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9184 matching a pp-number. Rename parameter var to var1.
9186 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9188 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9190 2011-10-08 Glenn Morris <rgm@gnu.org>
9192 * callint.c (Fcall_interactively): Give a more explicit error for the
9193 'c' case with a non-character input. (Bug#8479)
9195 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9197 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9199 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9200 lines that are hscrolled on the left.
9202 * dispnew.c (buffer_posn_from_coords): Account for a possible
9203 presence of header-line. (Bug#4426)
9205 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9207 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9208 Don't advertise functionality which we discourage or doesn't work.
9210 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9212 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9213 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9214 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9215 this makes Emacs dump core during garbage collection on rare
9216 occasions. sizeof is obviously inferior to offsetof here, so
9217 stick with offsetof.
9218 (GC_POINTER_ALIGNMENT): New macro.
9219 (mark_memory): Omit 3rd (offset) arg; caller changed.
9220 Don't assume EMACS_INT alignment is the same as pointer alignment.
9222 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9224 * keyboard.c (read_key_sequence_remapped): New var.
9225 (read_key_sequence): Compute remapping in the right buffer.
9226 (command_loop_1): Use read_key_sequence's remapping directly.
9228 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9230 * dired.c (file_name_completion): Don't expand file name.
9231 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9232 before checking file name handler.
9234 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9235 they've been requested explicitly (bug#9591).
9237 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9239 * keymap.c (Fsingle_key_description): Use make_specified_string
9240 instead of build_string to build string from push_key_description.
9243 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9245 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9246 This fixes a Y2038 bug on 64-bit hosts.
9247 * buffer.c (reset_buffer):
9248 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9249 (Fclear_buffer_auto_save_failure):
9250 Use 0, not -1, to represent an unset failure time, since time_t
9251 might not be signed.
9253 Remove dependency on glibc malloc internals.
9254 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9255 Move back here from lisp.h, but with their new implementations.
9256 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9257 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9258 * charset.c (charset_table_init): New static var.
9259 (syms_of_charset): Use it instead of xmalloc. This removes a
9260 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9261 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9262 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9263 Move back to alloc.c.
9264 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9265 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9267 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9269 * nsterm.m (windowDidResize): Call x_set_window_size only when
9270 ns_in_resize is true. Otherwise set pixelwidth/height and
9271 call change_frame_size (Bug#9628).
9273 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9275 Port --enable-checking=all to Fedora 14 x86-64.
9276 * charset.c (syms_of_charset): Also account for glibc malloc's
9277 internal overhead when calculating the initial malloc maximum.
9279 Port --enable-checking=all to Fedora 14 x86.
9280 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9282 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9283 (overrun_check_realloc, overrun_check_free):
9284 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9285 That way, xmalloc returns a properly-aligned pointer even if
9286 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9287 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9288 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9289 into account when calculating the initial malloc maximum.
9290 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9291 Move here from alloc.c, so that charset.c can use it too.
9292 Properly align; the old code wasn't right for common 32-bit hosts
9293 when configured with --enable-checking=all.
9294 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9295 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9297 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9299 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9302 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9304 * xdisp.c (compute_display_string_end): If there's no display
9305 string at CHARPOS, return -1.
9307 * bidi.c (bidi_fetch_char): When compute_display_string_end
9308 returns a negative value, treat the character as a normal
9309 character not covered by a display string. (Bug#9624)
9311 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9313 * lread.c (Fread_from_string): Fix typo in docstring.
9315 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9317 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9318 newline, reseat the iterator instead of bidi-iterating there one
9319 character at a time. (Bug#9610)
9320 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9321 TO_CHARPOS if the bidi iterator is at base embedding level.
9323 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9325 * lread.c (readevalloop): Use correct code for NBSP.
9326 (read1): Likewise. (Bug#9608)
9328 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9330 * dbusbind.c (Fdbus_register_signal): When service is not
9331 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9333 2011-09-25 Glenn Morris <rgm@gnu.org>
9335 * buffer.c (truncate-lines): Doc fix.
9337 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9339 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9340 (Fset_window_next_buffers): Doc fix.
9342 2011-09-24 Glenn Morris <rgm@gnu.org>
9344 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9346 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9348 Fix minor problems found by static checking.
9349 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9350 * indent.c (Fvertical_motion): Fix == vs = typo.
9352 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9354 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9355 Default value is now t. Doc fix.
9357 * indent.c (Fvertical_motion): Compute and apply the overshoot
9358 logic when moving up, not only when moving down. Fix the
9359 confusing name and values of the it_overshoot_expected variable;
9360 logic changes accordingly. (Bug#9254) (Bug#9549)
9362 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9363 CHARPOS is covered by a display string which includes newlines.
9364 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9365 is covered by a display string with embedded newlines.
9367 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9369 * dbusbind.c (Fdbus_register_signal): Add match rule to
9370 Vdbus_registered_objects_table. (Bug#9581)
9371 (Fdbus_register_method, Vdbus_registered_objects_table):
9374 2011-09-24 Jim Meyering <meyering@redhat.com>
9376 do not ignore write error for any output size
9377 The previous change was incomplete.
9378 While it makes emacs --batch detect the vast majority of stdout
9379 write failures, errors were still ignored whenever the output size is
9380 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9381 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9382 && echo FAIL: ignored write error
9383 FAIL: ignored write error
9384 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9385 && echo FAIL: ignored write error
9386 FAIL: ignored write error
9387 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9389 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9391 * emacs.c (Fkill_emacs): In noninteractive mode exit
9392 non-successfully if a write error occurred on stdout. (Bug#9574)
9394 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9396 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9399 * dispextern.h (struct it): Update the comment documenting what
9402 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9404 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9405 a display string, extend search for cursor position to end of row.
9406 (find_row_edges): If the row ends in a newline from a display
9407 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9408 Handle the case of a display string with multiple newlines.
9409 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9410 non-empty line. Fixes confusing cursor motion with arrow keys at
9411 the beginning of a line that starts with whitespace.
9413 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9415 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9418 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9420 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9423 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9425 * xdisp.c (display_line): Record maximum and minimum buffer
9426 positions even if no glyphs were produced (e.g., by a zero-width
9427 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9428 buffer positions that will be removed from the glyph row because
9430 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9431 column is beyond frame width: don't subtract 1 "pixel" when
9432 computing width of the stretch.
9433 (reseat_at_next_visible_line_start): Undo the change made on
9434 2011-09-17 that saved paragraph information and restored it after
9435 the call to `reseat'. (Bug#9545)
9437 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9439 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9440 and turn window cursor on if cleared (Bug#9415).
9442 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9444 * search.c (boyer_moore): Take unibyte characters from pattern
9445 literally. (Bug#9458)
9447 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9449 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9451 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9453 Fix minor problem found by static checking.
9454 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9455 initialized, to pacify gcc -Wuninitialized.
9457 * fileio.c: Report proper errno when syscall falls.
9458 (Finsert_file_contents): Save and restore errno,
9459 so that report_file_error outputs the correct diagnostic.
9460 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9462 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9464 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9466 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9468 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9469 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9471 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9473 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9474 about the current paragraph and restore it after the call to reseat.
9476 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9477 (bidi_find_paragraph_start): Search back for paragraph beginning
9478 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9479 (bidi_move_to_visually_next): Only trigger paragraph-related
9480 computations when the last character is a newline or at EOB, not
9481 just any NEUTRAL_B. (Bug#9470)
9483 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9484 truncated lines if point is covered by a display string. (Bug#9524)
9486 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9488 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9489 (cons_to_x_long): New function.
9490 (lisp_data_to_selection_data): Use it. Correct the test for
9491 short-versus-long data; it was negated. Break out of vector
9492 loop, for efficiency, when a long datum is discovered.
9494 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9496 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9498 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9500 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9501 GCC PR/17406) by declaring this function with external scope.
9503 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9505 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9506 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9508 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9510 * editfns.c (Fformat): Correctly handle text properties on "%%".
9512 2011-09-15 Eli Zaretskii <eliz@gnu.org>
9514 * xterm.c (x_draw_composite_glyph_string_foreground):
9515 * w32term.c (x_draw_composite_glyph_string_foreground):
9516 * term.c (encode_terminal_code):
9517 * composite.c (composition_update_it, get_composition_id):
9518 * xdisp.c (get_next_display_element)
9519 (fill_composite_glyph_string): Add comments about special meaning
9520 of TAB characters in a composition.
9522 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9524 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9525 This occurs when processing a multibyte format.
9526 Problem reported by Wolfgang Jenker.
9528 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9530 * xdisp.c (try_cursor_movement): Only check for exact match if
9531 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9533 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9535 Remove unused external symbols.
9536 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9537 * xdisp.c (calc_pixel_width_or_height): Now static.
9538 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9539 * indent.c (check_display_width):
9540 * w32term.c: Fix comment to match code.
9541 * xterm.c, xterm.h (x_catching_errors): Remove.
9543 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9545 * xselect.c: Use signed conversions more consistently (Bug#9498).
9546 (selection_data_to_lisp_data): Assume incoming selection data are
9547 signed integers, not unsigned. This is to be consistent with
9548 outgoing selection data, which was modified to use signed integers
9549 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9550 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9551 expects long, not unsigned long.
9553 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9555 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9556 computation of loop end. Reported by Johan Bockgård
9559 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9561 * frame.c (Fother_visible_frames_p): Function deleted.
9563 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9565 * indent.c (compute_motion): Process display vector front to back
9566 rather than the other way around. (Bug#2496)
9568 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9570 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9572 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9574 * minibuf.c (Fread_from_minibuffer): Doc fix.
9576 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9578 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9579 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9581 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9583 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9584 value for non-existent files.
9586 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9588 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9589 set its "size" to -1. This will set the modtime_size field of
9590 the corresponding buffer to -1, which is what
9591 verify-visited-file-modtime expects for files that do not exist.
9594 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9596 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9598 * lisp.h: ... from here. push_key_description is no longer
9599 defined in keyboard.c, so its declaration should not be in
9600 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9601 logically belongs with push_key_description.
9603 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9605 * buffer.h: Include <sys/types.h> instead of <time.h>.
9606 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9607 Problem reported by Herbert J. Skuhra.
9609 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9611 * xml.c (parse_region): Make the parsing work for
9612 non-comment-starting XML files again (bug#9144).
9614 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9616 * image.c (gif_load): Fix calculation of bottom and right corner.
9619 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9621 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9622 redisplay in small windows.
9624 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9626 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9628 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9630 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9631 Operate on live windows only.
9633 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
9635 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
9637 2011-09-07 Eli Zaretskii <eliz@gnu.org>
9639 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
9640 only under bidi iteration.
9642 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
9644 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9646 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9648 isnan: Fix porting problem to Solaris 10 with bundled gcc.
9649 Without this fix, the command to link temacs failed due to an
9650 undefined symbol __builtin_isnan. This is because
9651 /usr/include/iso/math_c99.h #defines isnan(x) to
9652 __builtin_isnan(x), but the bundled gcc, which identifies itself
9653 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
9655 * floatfns.c (isnan): #undef, and then #define to a clone of
9657 (Fisnan): Always define, since it's always available now.
9658 (syms_of_floatfns): Always define isnan at the Lisp level.
9660 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9662 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
9664 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9666 * fileio.c: Fix bugs with large file offsets (Bug#9428).
9667 The previous code assumed that file offsets (off_t values) fit in
9668 EMACS_INT variables, which is not true on typical 32-bit hosts.
9669 The code messed up by falsely reporting buffer overflow in cases
9670 such as (insert-file-contents "big" nil 1 2) into an empty buffer
9671 when "big" contains more than 2**29 bytes, even though this
9672 inserts just one byte and does not overflow the buffer.
9673 (Finsert_file_contents): Store file offsets as off_t
9674 values, not as EMACS_INT values. Check for overflow when
9675 converting between EMACS_INT and off_t. When checking for
9676 buffer overflow or for overlap, take the offsets into account.
9677 Don't use EMACS_INT for small values where int suffices.
9678 When checking for overlap, fix a typo: ZV was used where
9679 ZV_BYTE was intended.
9680 (Fwrite_region): Don't assume off_t fits into 'long'.
9681 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
9683 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
9685 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
9687 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9689 sprintf-related integer and memory overflow issues (Bug#9412).
9691 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
9692 (esprintf, exprintf, evxprintf): New functions.
9693 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
9694 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
9695 (modify_event_symbol): Do not assume that the length of
9696 name_alist_or_stem is safe to alloca and fits in int.
9697 (Fexecute_extended_command): Likewise for function name and binding.
9698 (Frecursion_depth): Wrap around reliably on integer overflow.
9699 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
9700 since some callers pass EMACS_INT values.
9701 (Fsingle_key_description): Don't crash if symbol name contains more
9702 than MAX_ALLOCA bytes.
9703 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
9704 (get_minibuffer): Arg is now EMACS_INT, not int.
9705 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
9706 (esprintf, exprintf, evxprintf): New decls.
9707 * window.h (command_loop_level, minibuf_level): Reflect API changes.
9709 * dbusbind.c (signature_cat): New function.
9710 (xd_signature, Fdbus_register_signal):
9711 Do not overrun buffer; instead, report string overflow.
9713 * dispnew.c (add_window_display_history): Don't overrun buffer.
9714 Truncate instead; this is OK since it's just a log.
9716 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
9717 even if the time zone offset is outlandishly large.
9718 Don't mishandle offset == INT_MIN.
9720 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
9721 when creating daemon; the previous buffer-overflow check was incorrect.
9723 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
9724 which has the guts of the old verror function.
9726 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
9727 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
9729 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
9730 (font_unparse_xlfd): Don't blindly alloca long strings.
9731 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
9732 fits in int, when using sprintf. Use single snprintf to count
9733 length of string rather than counting it via multiple sprintfs;
9734 that's simpler and more reliable.
9735 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
9736 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
9737 sprintf, in case result does not fit in int.
9739 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
9740 (fontset_from_font): Print it.
9742 * frame.c (tty_frame_count): Now printmax_t, not int.
9743 (make_terminal_frame, set_term_frame_name): Print it.
9744 (x_report_frame_params): In X, window IDs are unsigned long,
9745 not signed long, so print them as unsigned.
9746 (validate_x_resource_name): Check for implausibly long names,
9747 and don't assume name length fits in 'int'.
9748 (x_get_resource_string): Don't blindly alloca invocation name;
9749 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
9752 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
9753 (xg_check_special_colors, xg_set_geometry):
9754 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
9756 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
9757 Use esprintf, not sprintf, in case result does not fit in int.
9759 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9760 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
9761 it as a large positive number.
9762 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
9763 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9765 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
9766 in case result does not fit in int.
9768 * print.c (float_to_string): Detect width overflow more reliably.
9769 (print_object): Make sprintf buffer a bit bigger, to avoid potential
9770 buffer overrun. Don't assume list length fits in 'int'. Treat
9771 print length of 0 as 0, not as infinity; to be consistent with other
9772 uses of print length in this function. Don't overflow print length
9773 index. Don't assume hash table size fits in 'long', or that
9774 vectorlike size fits in 'unsigned long'.
9776 * process.c (make_process): Use printmax_t, not int, to format
9777 process-name gensyms.
9779 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
9781 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
9782 to avoid potential buffer overrun.
9784 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
9785 if X resource line is longer than 512 bytes.
9787 * xfns.c (x_window): Make sprintf buffer a bit bigger
9788 to avoid potential buffer overrun.
9790 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
9792 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
9794 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9796 Integer overflow fixes for scrolling, etc.
9797 Without these, Emacs silently mishandles large integers sometimes.
9798 For example, "C-u 4294967297 M-x recenter" was treated as if
9799 it were "C-u 1 M-x recenter" on a typical 64-bit host.
9801 * xdisp.c (try_window_id): Check Emacs fixnum range before
9802 converting to 'int'.
9804 * window.c (window_scroll_line_based, Frecenter):
9805 Check that an Emacs fixnum is in range before assigning it to 'int'.
9806 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
9807 values converted from Emacs fixnums.
9808 (Frecenter): Don't wrap around a line count if it is out of 'int'
9809 range; instead, treat it as an extreme value.
9810 (Fset_window_configuration, compare_window_configurations):
9811 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
9813 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
9814 that can exceed INT_MAX. Check that EMACS_INT value is in range
9815 before assigning it to the (possibly-narrower) index.
9816 (match_limit): Don't assume that a fixnum can fit in 'int'.
9818 * print.c (print_object): Use ptrdiff_t, not int, for index that can
9821 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
9822 (Fvertical_motion): Don't wrap around LINES values that don't fit
9823 in 'int'. Instead, treat them as extreme values. This is good
9824 enough for windows, which can't have more than INT_MAX lines anyway.
9826 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9828 * Require libxml/parser.h to avoid compilation warning.
9830 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
9832 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
9833 since this reportedly can destroy thread storage.
9835 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
9837 * syntax.c (find_defun_start): Update all cache variables if
9838 exiting early (Bug#9401).
9840 2011-08-30 Eli Zaretskii <eliz@gnu.org>
9842 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
9844 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
9845 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
9846 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
9848 * term.c (tty_append_glyph): New function.
9849 (produce_stretch_glyph): Static function and its prototype deleted.
9851 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
9854 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
9856 * image.c (parse_image_spec): Check for nonnegative, not for positive,
9857 when checking :margin (Bug#9390).
9858 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
9859 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
9860 so that the name doesn't mislead. All uses changed.
9862 2011-08-28 Johan Bockgård <bojohan@gnu.org>
9864 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
9867 2011-08-27 Eli Zaretskii <eliz@gnu.org>
9869 * xdisp.c (move_it_to): Don't bail out early when reaching
9870 position beyond to_charpos, if we are scanning backwards.
9871 (move_it_vertically_backward): When DY == 0, make sure we get to
9872 the first character in the line after the newline.
9874 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
9876 * ccl.c: Improve and simplify overflow checking (Bug#9196).
9877 (ccl_driver): Do not generate an out-of-range pointer.
9878 (Fccl_execute_on_string): Remove unnecessary check for
9879 integer overflow, noted by Stefan Monnier in
9880 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
9881 Remove a FIXME that didn't need fixing.
9882 Simplify the newly-introduced buffer reallocation code.
9884 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
9886 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
9888 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
9890 Integer and memory overflow issues (Bug#9196).
9892 * doc.c (get_doc_string): Rework so that
9893 get_doc_string_buffer_size is the actual buffer size, rather than
9894 being 1 less than the actual buffer size; this makes xpalloc more
9897 * image.c (x_allocate_bitmap_record, cache_image):
9898 * xselect.c (Fx_register_dnd_atom):
9899 Simplify previous changes by using xpalloc.
9901 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
9902 since either will do and ptrdiff_t is convenient with xpalloc.
9904 * charset.c (charset_table_size)
9905 (struct charset_sort_data.priority): Now ptrdiff_t.
9906 (charset_compare): Don't overflow if priorities differ greatly.
9907 (Fsort_charsets): Don't assume list length fits in int.
9908 Check for size-calculation overflow when allocating sort data.
9909 (syms_of_charset): Allocate an initial charset table that is
9910 just under 64 KiB, to avoid problems with glibc malloc and mmap.
9912 * cmds.c (internal_self_insert): Check for size-calculation overflow.
9914 * composite.h (struct composition.glyph_len): Now int, not unsigned.
9915 The actual value is always <= INT_MAX, and leaving it unsigned made
9916 overflow checking harder.
9918 * dispextern.h (struct glyph_matrix.rows_allocated)
9919 (struct face_cache.size): Now ptrdiff_t, for convenience in use
9920 with xpalloc. The values are still always <= INT_MAX.
9922 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
9924 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.

9930 (revalidate_region_cache, know_region_cache, region_cache_forward)
9931 (region_cache_backward, pp_cache):
9932 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed

9935 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

9952 Don't update size of array until after memory allocation succeeds,
9953 because xmalloc/xrealloc may not return.
9954 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
9955 now that we have proper integer overflow checking.
9956 (record_overlay_string, overlay_strings): Catch overflows when

9959 * callproc.c (Fcall_process): Check for size overflow when
9960 calculating size of args2.

10006 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10008 * emacs.c (main): Do not reallocate argv, since there is a null at
10009 the end that can be overwritten, and this way there's no need to
10010 worry about size-calculation overflow.
10011 (sort_args): Check for size-calculation overflow.
10013 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10019 Check for integer overflow.
10020 (x_set_alpha): Do not assume XINT fits in int.
10022 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10023 This is for the members text_lines, text_cols, total_lines, total_cols,
10024 where the system imposes an 'int' limit.
10026 * fringe.c (Fdefine_fringe_bitmap):
10027 Don't update size until alloc works.

10033 Check for size-calculation overflow.
10034 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10035 do, as we prefer signed integers.

10041 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
10042 * gtkutil.h: Change prototypes to match the above.
10044 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

10140 (X_LONG_MIN): New macros.
10141 Use them to make the following changes clearer.
10142 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

10145 (SELECTION_QUANTUM): Remove, replacing with ...
10146 (selection_quantum): ... new function, which avoids overflow.
10148 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10149 assumption that selection length fits in 'int'.

10166 Don't store size until memory allocation succeeds.
10167 (x_get_window_property): Plug memory leak on memory exhaustion.
10168 Don't double-block input; malloc is safe here. Don't assume 2**34
10169 - 4 fits in unsigned long. Add an xassert to check
10170 XGetWindowProperty overflow. Be more careful about overflow
10171 calculations, and distinguish size from memory overflow better.
10172 (receive_incremental_selection): When tracing, don't assume
10173 unsigned int is less than INT_MAX.
10174 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10178 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10179 result parameters unless successful. Rely on cons_to_unsigned
10180 to report problems with elements; the old code wasn't right anyway.
10181 (x_check_property_data): Check for int overflow; we cannot use
10182 a wider type due to X limits.

10215 * lisp.h (hash_lookup, hash_put):
10216 * minibuf.c (Ftest_completion):
10217 Use ptrdiff_t for hash table indexes, not int (which is too
10218 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

10221 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10222 Add a FIXME comment about memory leaks.

10230 with outlandish widths.
10231 * character.h (sanitize_tab_width): Rename from sanitize_width,

10257 (make_lispy_movement): Use same integer type in forward decl
10258 that is used in the definition.

10262 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10263 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10264 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10265 length, not size_t. Use ptrdiff_t for index, not int.
10266 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10267 possibility of integer overflow.

10295 Prefer int to unsigned where either will do.
10296 (tiff_handler): New function, combining the cores of the
10297 old tiff_error_handler and tiff_warning_handler.
10298 This function is rewritten to use vsnprintf and thereby avoid
10299 stack buffer overflows. It uses only the features of vsnprintf
10300 that are common to both POSIX and native Microsoft.
10301 (tiff_error_handler, tiff_warning_handler): Use it.
10302 (tiff_load, gif_load, imagemagick_load_image):
10303 Don't assume :index value fits in 'int'.

10306 the integer types that MagickCropImage accepts. Don't assume
10307 Vimagemagick_render_type has a nonnegative value. Don't assume

10323 (handle_single_display_spec): If the display spec is of the form
10324 `(space ...)', and specifies display in the text area, return 2
10326 (try_cursor_movement): Check for the need to scroll more
10327 accurately, and prefer exact match for point under bidi.
10328 Don't advance `row' beyond the last row of the window.

10346 buffers, return left-to-right.
10347 (set_cursor_from_row): Consider candidate row a win if its glyph

10349 positioning on the newline at EOL of R2L text within L2R
10350 paragraph, and vice versa.
10351 (try_cursor_movement): Check continued rows, in addition to
10352 continuation rows. Fixes unwarranted scroll when point enters a
10353 continued line of R2L text within an L2R paragraph, or vice versa.
10354 (cursor_row_p): Consider the case of point being equal to
10355 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10356 from the end of a short line to the beginning of a continued line
10357 of R2L text within L2R paragraph.
10358 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

10376 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
10377 extra slot even if the purpose is char-code-property-table.
10379 2011-08-23 Eli Zaretskii <eliz@gnu.org>
10381 * xdisp.c (redisplay_window): When computing centering_position,
10382 account for the height of the header line. (Bug#8874)
10384 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10385 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10386 candidate is selected by the mouse, and that candidate has a
10387 composed character under the mouse.
10389 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10390 coordinates reported by pos-visible-in-window-p for a composed
10391 character in column zero.
10393 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

10400 consider it a hit if to_charpos is anywhere in the range of the
10401 composed buffer positions.
10403 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10405 * image.c (gif_load): Don't assume that each subimage has the same
10406 dimensions as the base image. Handle disposal method that is
10407 "undefined" by the gif spec (Bug#9335).

10414 2011-08-19 Eli Zaretskii <eliz@gnu.org>
10416 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
10417 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10418 from an Org mode buffer to a Speedbar frame.
10420 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10421 a composition, take its buffer position from IT->cmp_it.charpos.
10422 Fixes cursor positioning at the beginning of a line that begins
10423 with a composed character.
10425 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10427 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10428 character bidirectional type, use STRONG_L instead. Fixes crashes
10429 in a buffer produced by `describe-categories'.
10431 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10432 members before the level stack, so they would be saved and
10433 restored when copying iterator state. Fixes incorrect reordering
10434 around TABs covered by display properties.
10436 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10438 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10443 (internal_condition_case_2, internal_condition_case_n):
10444 Remove unnecessary aborts (Bug#9081).
10446 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10448 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10449 has no `load' handler, try opening the file locally. (Bug#9311)
10451 2011-08-16 Ken Brown <kbrown@cornell.edu>
10453 * gmalloc.c: Expand comment.
10455 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10508 * xdisp.c (move_it_in_display_line_to): Don't invoke
10509 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10510 ppos_it. Fixes vertical cursor motion when line beginning is
10511 covered by an image. (Bug#9296)
10513 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10515 * nsterm.h (ns_run_ascript): Declare.

10519 (ns_run_ascript): New function.
10520 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10521 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10522 the event loop. Get status from as_status (Bug#7276).
10524 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10525 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10526 the event loop (Bug#7276).
10528 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10530 * gnutls.c (QCgnutls_bootprop_priority)

10552 (Fnetwork_interface_list): Allocate in increments of bytes instead
10553 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10554 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10556 (struct ifflag_def): notrailers is smart on OSX.
10557 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10558 Get hardware address with getifaddrs if available.
10560 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10562 * xdisp.c (iterate_out_of_display_property): xassert that
10563 IT->position is set to within IT->object's boundaries. Break from
10564 the loop as soon as EOB is reached; avoids infloops in redisplay
10565 when IT->position is set up wrongly due to some bug.
10566 Set IT->current to match the bidi iterator unconditionally.
10567 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10568 entry. Force push_it to save on the stack the current
10569 buffer/string position, to be restored by pop_it. Fix flags in
10570 the iterator structure wrt the object coming from a display
10571 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10572 properties. (Bug#9284)
10574 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10576 * fontset.c (fontset_get_font_group): Add proper type checks.

10606 2011-08-07 Juri Linkov <juri@jurta.org>
10608 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10609 to show the arg `TIME' instead of `TIMEVAL'.
10611 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10613 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10614 display property strides EOL and includes a newline, as in
10615 longlines-mode. (Bug#9254)
10616 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10617 word-wrap under bidirectional display. (Bug#9224)
10619 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10620 is non-zero, even if the data buffer is NULL. Fixes a crash in
10621 vertical-motion with longlines-mode. (Bug#9254)
10623 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10625 * bidi.c <bidi_cache_total_alloc>: Now static.

10628 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10631 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10632 amount allocated this far in `bidi_cache_total_alloc'.
10633 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10634 non-zero, only free the data buffer without restoring the cache
10635 contents. All callers changed.
10637 * dispextern.h (bidi_unshelve_cache): Update prototype.
10639 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10640 (move_it_in_display_line, move_it_to)
10641 (move_it_vertically_backward, move_it_by_lines): Replace the call
10642 to xfree to an equivalent call to bidi_unshelve_cache.
10643 (move_it_in_display_line_to): Fix logic of returning
10644 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

10665 * xterm.c (x_find_topmost_parent): New function.
10666 (x_set_frame_alpha): Find topmost parent window with
10667 x_find_topmost_parent and set the property there also (bug#9181).
10668 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.

10699 * bidi.c (bidi_fetch_char): Accept an additional argument
10700 DISP_PROP_P, and pass it to compute_display_string_pos.
10701 Only handle text covered by a display string if DISP_PROP_P is returned
10702 non-zero. All callers of bidi_fetch_char changed.
10704 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

10730 * regex.c (re_comp): Protoize.
10731 (re_exec): Fix return type.
10732 (regexec): Fix type of `ret'. (Bug#9203)
10734 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10736 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
10737 This is needed if max-image-size is a floating-point number.

10786 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10788 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
10789 Without this fix, if a signal arrives just after memory fills up,
10790 'malloc' might be invoked reentrantly.
10792 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
10793 In other words, assume that every image size is allowed, on non-X
10794 hosts. This assumption is probably wrong, but it lets Emacs compile.

10816 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
10817 (bidi_cache_find_level_change, bidi_cache_ensure_space)
10818 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
10819 (bidi_find_other_level_edge):
10820 Use ptrdiff_t instead of EMACS_INT where either will do.
10821 This works better on 32-bit hosts configured --with-wide-int.
10822 (bidi_cache_ensure_space): Check for size-calculation overflow.
10823 Use % rather than repeated addition, for better worst-case speed.
10824 Don't set bidi_cache_size until after xrealloc returns, because it
10826 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
10827 (bidi_cache_ensure_space): Also check that the bidi cache size
10828 does not exceed that of the largest Lisp string or buffer. See Eli
10829 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
10831 * alloc.c (__malloc_size_t): Remove.
10832 All uses replaced by size_t. See Andreas Schwab's note
10833 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
10835 * image.c: Improve checking for integer overflow.
10836 (check_image_size): Assume that f is nonnull, since
10837 it is always nonnull in practice. This is one less thing to
10838 worry about when checking for integer overflow later.
10839 (x_check_image_size): New function, which checks for integer
10840 overflow issues inside X.
10841 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
10842 This removes the need for a memory_full check.
10843 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
10844 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
10845 (xbm_read_bitmap_data): Change locals back to 'int', since
10846 their values must fit in 'int'.
10847 (xpm_load_image, png_load, tiff_load):
10848 Invoke x_create_x_image_and_pixmap earlier,
10849 to avoid much needless work if the image is too large.
10850 (tiff_load): Treat overly large images as if
10851 x_create_x_image_and_pixmap failed, not as malloc failures.
10852 (gs_load): Use x_check_image_size.
10854 * gtkutil.c: Omit integer casts.
10855 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
10856 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
10858 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
10860 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
10861 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
10862 would wrongly return t on a 64-bit host.
10864 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
10865 The plain *_OVERFLOW macros run afoul of GCC bug 49705
10866 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
10867 and therefore cause GCC to emit a bogus diagnostic in some cases.
10869 * image.c: Integer signedness and overflow and related fixes.
10870 This is not an exhaustive set of fixes, but it's time to
10871 record what I've got.
10872 (lookup_pixel_color, check_image_size): Remove redundant decls.
10873 (check_image_size): Don't assume that arbitrary EMACS_INT values
10874 fit in 'int', or that arbitrary 'double' values fit in 'int'.
10875 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
10876 (tiff_load, imagemagick_load_image):
10877 Check for overflow in size calculations.
10878 (x_create_x_image_and_pixmap): Remove unnecessary test for
10879 xmalloc returning NULL; that can't happen.
10880 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
10881 (xpm_color_bucket): Use better integer hashing function.
10882 (xpm_cache_color): Don't possibly over-allocate memory.
10883 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
10884 (gif_memory_source):
10885 Use ptrdiff_t, not int or size_t, to record sizes.
10886 (png_load): Don't assume values greater than 2**31 fit in 'int'.
10887 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
10888 either works, as we prefer signed integers.
10889 (tiff_read_from_memory, tiff_write_from_memory):
10890 Return tsize_t, not size_t, since that's what the TIFF API wants.
10891 (tiff_read_from_memory): Don't fail simply because the read would
10892 go past EOF; instead, return a short read.
10893 (tiff_load): Omit no-longer-needed casts.
10894 (Fimagemagick_types): Don't assume size fits into 'int'.
10896 Improve hashing quality when configured --with-wide-int.
10897 * fns.c (hash_string): New function, taken from sxhash_string.
10898 Do not discard information about ASCII character case; this
10899 discarding is no longer needed.
10900 (sxhash-string): Use it. Change sig to match it. Caller changed.
10901 * lisp.h: Declare it.
10902 * lread.c (hash_string): Remove, since we now use fns.c's version.
10903 The fns.c version returns a wider integer if --with-wide-int is
10904 specified, so this should help the quality of the hashing a bit.
10906 * emacs.c: Integer overflow minor fix.
10907 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
10908 Define only if GNU_LINUX.
10909 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
10911 * dispnew.c: Integer signedness and overflow fixes.
10912 Remove unnecessary forward decls, that were a maintenance hassle.
10913 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
10915 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
10916 (scrolling_window): Use ptrdiff_t, not int, for byte count.
10917 (prepare_desired_row, line_draw_cost):
10918 Use int, not unsigned, where either works.
10919 (save_current_matrix, restore_current_matrix):
10920 Use ptrdiff_t, not size_t, where either works.
10921 (init_display): Check for overflow more accurately, and without
10922 relying on undefined behavior.
10924 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
10925 Remove, replacing with the new symbols in lisp.h. All uses changed.
10926 * fileio.c (make_temp_name):
10927 * filelock.c (lock_file_1, lock_file):
10928 * xdisp.c (message_dolog):
10929 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
10930 Use pMd etc. instead.
10931 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
10932 replacing the pWIDE etc. symbols removed from editfns.c.
10934 * keyboard.h (num_input_events): Now uintmax_t.
10935 This is (very slightly) less likely to mess up due to wraparound.
10938 * buffer.c: Integer signedness fixes.
10939 (alloc_buffer_text, enlarge_buffer_text):
10940 Use ptrdiff_t rather than size_t when either will do, as we prefer
10943 * alloc.c: Integer signedness and overflow fixes.
10944 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
10945 (__malloc_size_t): Default to size_t, not to int.
10946 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
10947 (Fgarbage_collect, mark_object_loop_halt, mark_object):
10948 Prefer ptrdiff_t to size_t when either would do, as we prefer
10950 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
10951 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
10952 Now const. Initialize with values that are in range even if char
10954 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
10955 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
10956 These functions do the right thing with sizes > 2**32.
10957 (check_depth): Now ptrdiff_t, not int.
10958 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
10959 Adjust to new way of storing sizes. Check for size overflow bugs
10961 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
10962 slightly wrong anyway, as it missed one instance of
10963 XMALLOC_OVERRUN_CHECK_OVERHEAD.
10964 (refill_memory_reserve): Omit needless cast to size_t.
10965 (mark_object_loop_halt): Mark as externally visible.
10967 * xselect.c: Integer signedness and overflow fixes.
10968 (Fx_register_dnd_atom, x_handle_dnd_message):
10969 Use ptrdiff_t, not size_t, since we prefer signed.
10970 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
10971 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
10972 x_dnd_atoms_size and x_dnd_atoms_length.
10974 * doprnt.c: Prefer signed to unsigned when either works.
10976 * doprnt.c (doprnt):
10978 * xdisp.c (vmessage):
10979 Use ptrdiff_t, not size_t, when using or implementing doprnt,
10980 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
10981 prefer signed arithmetic to avoid comparison confusion.
10982 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
10983 but is a bit tricky.
10985 Assume freestanding C89 headers, string.h, stdlib.h.
10986 * data.c, doprnt.c, floatfns.c, print.c:
10987 Include float.h unconditionally.
10988 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10989 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10990 * regex.c: Likewise for stddef.h, string.h.
10991 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10992 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10993 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10994 (STDC_HEADERS): Remove obsolete defines.
10995 * sysdep.c: Include limits.h unconditionally.
10997 Assume support for memcmp, memcpy, memmove, memset.
10998 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10999 * regex.c (memcmp, memcpy):
11000 Remove; we assume C89 now.
11002 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11003 (__malloc_safe_bcopy): Remove; no longer needed.
11005 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11006 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11007 well either way, and we prefer signed to unsigned.
11009 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11011 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11012 closes the connection while we're reading (bug#9182).
11014 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11016 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11017 are specified (Bug#9168).
11019 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11021 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11022 Found by GCC static checking and --with-wide-int on a 32-bit host.
11024 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11026 * xdisp.c (compute_display_string_pos): Fix logic of caching
11027 previous display string position. Initialize cached_prev_pos to
11028 -1. Fixes slow-down at the beginning of a buffer.
11030 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11032 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11033 for attrs[LFACE_FONTSET_INDEX].
11035 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11037 * xml.c (parse_region): Remove unused local
11038 that was recently introduced.
11040 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11042 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11043 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11045 * xdisp.c (move_it_in_display_line_to): Record the best matching
11046 position for TO_CHARPOS while scanning the line, and restore it on
11047 exit if none of the characters scanned was an exact match.
11048 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11049 when exact match is impossible due to invisible text, and the
11050 lines are truncated.
11052 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11054 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11057 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11059 Fix a significant slow-down of cursor motion with C-n, C-p,
11060 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11061 auto-repeat under bidi redisplay in fontified buffers.
11062 * xdisp.c (compute_stop_pos_backwards): New function.
11063 (next_element_from_buffer): Call compute_stop_pos_backwards to
11064 find a suitable prev_stop when we find ourselves before
11066 (reseat): Don't look for prev_stop, as that could mean a very long
11068 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11069 <cached_disp_overlay_modiff>: Cache for last found display string
11071 (compute_display_string_pos): Return the cached position if asked
11072 about the same buffer in the same area of character positions, and
11073 the buffer wasn't changed since the time the display string
11074 position was cached.
11076 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11078 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11079 is an integer, which is important for empty lines. (Bug#9149)
11081 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11083 * frame.c (Fmodify_frame_parameters): In tty case, update the
11084 default face if necessary (Bug#4238).
11086 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11088 * editfns.c (Fstring_to_char): No need to explain what a character
11089 is in the docstring (Bug#6576).
11091 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11093 * xml.c (parse_region): Make sure we always return a tree.
11095 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11097 * xml.c (parse_region): If a document contains only comments,
11100 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11102 * xml.c (make_dom): Return comments, too.
11104 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11107 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11108 and the surrounding thread.
11109 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11110 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11111 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11113 * s/openbsd.h (BROKEN_SIGIO): Define.
11114 * unexelf.c (unexec) [__OpenBSD__]:
11115 Don't update the .mdebug section of the Alpha COFF symbol table.
11117 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11119 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11122 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11124 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11125 This fixes some race conditions on the permissions of any newly
11128 * alloc.c (valid_pointer_p): Use pipe, not open.
11129 This fixes some permissions issues when debugging.
11131 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11132 If fchown fails to set both uid and gid, try to set just gid,
11133 as that is sometimes allowed. Adjust the file's mode to eliminate
11134 setuid or setgid bits that are inappropriate if fchown fails.
11136 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11138 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11139 to compare Lisp_Objects.
11140 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11141 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11142 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11144 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11146 * lread.c (read_integer): Unread even EOF character.
11147 (read1): Likewise. Properly record start position of symbol.
11149 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11150 symbol character follows.
11152 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11154 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11155 This works around a problem with the previous change to Fcopy_file.
11156 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11157 and without this change, GCC might complain about discarding
11158 fchown's return value.
11160 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11162 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11164 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11166 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11168 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11170 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11171 it's used from the C level.
11173 * process.c: Use the same condition for POLL_FOR_INPUT in both
11174 keyboard.c and process.c (bug#1858).
11176 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11178 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11179 (Fgnutls_boot): Use it.
11181 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11183 * doc.c (Fsubstitute_command_keys): Revert last change.
11185 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11187 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11188 quotes the next character, and doesn't affect other longer
11189 sequences (bug#8935).
11191 * lread.c (syms_of_lread): Clarify that is isn't only
11192 `eval-buffer' and `eval-defun' that's affected by
11193 `lexical-binding' (bug#8460).
11195 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11197 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11198 bidi redisplay when a line includes both an image and is truncated.
11200 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11202 Fix minor problems found by static checking.
11203 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11204 (elsz): Now a signed constant, not a size_t var. We prefer signed
11205 types to unsigned, to avoid integer comparison confusion. Without
11206 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11207 "cannot optimize loop, the loop counter may overflow", a symptom
11209 * indent.c (Fvertical_motion): Mark locals as initialized.
11210 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11212 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11214 * search.c (Fre_search_backward): Mention `case-fold-search' in
11215 all the re_search_* functions (bug#8138).
11217 * keyboard.c (Fopen_dribble_file): Document when the file is
11220 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11222 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11225 Support bidi reordering of display and overlay strings.
11226 * xdisp.c (compute_display_string_pos)
11227 (compute_display_string_end): Accept additional argument STRING.
11228 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11229 (reseat_to_string): Initialize bidi_it->string.s and
11230 bidi_it->string.schars.
11231 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11232 NULL (avoids a crash in bidi_paragraph_init).
11233 Initialize itb.string.lstring.
11234 (init_iterator): Call bidi_init_it only of a valid
11235 buffer position was specified. Initialize paragraph_embedding to
11237 (reseat_to_string): Initialize the bidi iterator.
11238 (display_string): If we need to ignore text properties of
11239 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11240 original value of -1 will not work with bidi.)
11241 (compute_display_string_pos): First arg is now struct
11242 `text_pos *'; all callers changed. Support display properties on
11244 (compute_display_string_end): Support display properties on Lisp
11246 (init_iterator, reseat_1, reseat_to_string): Initialize the
11247 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11248 when iterating on a string not from display properties).
11249 (compute_display_string_pos, compute_display_string_end):
11250 Fix calculation of the object to scan. Fixes an error when using
11252 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11253 base_level_stop; instead, set base_level_stop to BEGV.
11254 Fixes crashes in vertical-motion.
11255 (next_element_from_buffer): Improve commentary for when
11256 the iterator is before prev_stop.
11257 (init_iterator): Initialize bidi_p from the default value of
11258 bidi-display-reordering, not from buffer-local value. Use the
11259 buffer-local value only if initializing for buffer iteration.
11260 (handle_invisible_prop): Support invisible properties on strings
11261 that are being bidi-reordered.
11262 (set_iterator_to_next): Support bidi reordering of C strings and
11264 (next_element_from_string): Support bidi reordering of Lisp
11266 (handle_stop_backwards): Support Lisp strings as well.
11267 (display_string): Support display of R2L glyph rows.
11268 Use IT_STRING_CHARPOS when displaying from a Lisp string.

11732 * alloc.c (mark_buffer):
11733 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
11734 (clone_per_buffer_values): Don't assume that
11735 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
11736 This isn't true in general, and it's particularly not true
11737 if Emacs is configured with --with-wide-int.
11738 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
11739 New macros, used in the buffer.c change.

11775 Random fixes. E.g., (random) never returned negative values.
11776 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
11777 subseconds part to the entropy, as that's a bit more random.
11778 Prefer signed to unsigned, since the signedness doesn't matter and
11779 in general we prefer signed. When given a limit, use a
11780 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
11781 latter isn't right if USE_2_TAGS_FOR_INTS.
11782 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
11783 not 0..VALMASK. Don't discard "excess" bits that random () returns.
11785 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11787 * textprop.c (text_property_stickiness):
11788 Obey Vtext_property_default_nonsticky.

11795 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
11796 This is more efficient than Ffile_directory_p and avoids a minor race.
11798 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
11800 * buffer.c (Foverlay_put): Say what the return value is
11803 * fileio.c (barf_or_query_if_file_exists): Check first if the file
11804 is a directory before asking whether to use the file name
11806 (barf_or_query_if_file_exists): Make the "File is a directory"
11807 error be more correct.
11809 * fns.c (Frequire): Remove the mention of the .gz files, since
11810 that's installation-specific, but keep the mention of
11811 `get-load-suffixes'.
11813 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
11815 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

11821 (syms_of_gnutls): Remove duplicate DEFSYM for
11822 Qgnutls_bootprop_verify_hostname_error, an error for
11823 Qgnutls_bootprop_verify_error (which is no longer used).
11825 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
11826 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
11827 Also (re)move comments that are misplaced or no longer relevant.
11829 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11831 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

11890 (syms_of_keymap): Defsubr make-composed-keymap.
11891 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

11928 * eval.c (struct backtrace): Simplify and port the data structure.
11929 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
11930 signed bit field, as this assumption is not portable and it makes
11931 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
11932 "char debug_on_exit : 1" as this is not portable either; instead,
11933 use the portable "unsigned int debug_on_exit : 1". Remove unused
11934 member evalargs. Remove obsolete comments about cc bombing out.
11936 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12146 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
12147 Move to minibuffer.el.
12149 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12151 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12152 The following patches are for when GLYPH_DEBUG && !XASSERT.
12153 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12154 * dispnew.c (flush_stdout):
12155 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12156 Mark as externally visible.
12157 * dispnew.c (check_window_matrix_pointers): Now static.
12158 * dispnew.c (window_to_frame_vpos):
12159 * xfns.c (unwind_create_frame):
12160 * xterm.c (x_check_font): Remove unused local.
12161 * scroll.c (CHECK_BOUNDS):
12162 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12163 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
12164 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
12165 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
12166 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12168 (debug_method_add): Use va_list and vsprintf rather than relying
12169 on undefined behavior with wrong number of arguments.
12170 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12171 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12172 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12173 since we're not interested in debugging glyphs with old libraries.
12174 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12175 GCC 4.6.0's static checking.
12177 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12179 Integer overflow and signedness fixes (Bug#8873).

12188 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
12189 (x_create_bitmap_from_xpm_data):
12190 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
12191 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
12193 * xfaces.c (load_pixmap):
12194 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12195 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12196 (.bitmaps_last, struct x_output.icon_bitmap):
12197 Use ptrdiff_t, not int, for bitmap indexes.
12198 (x_allocate_bitmap_record): Check for size overflow.
12199 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12201 Use ptrdiff_t, not int, for overlay counts.
12202 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12203 * editfns.c (overlays_around, get_pos_property):
12204 * textprop.c (get_char_property_and_overlay):
12205 * xdisp.c (next_overlay_change, note_mouse_highlight):
12206 * xfaces.c (face_at_buffer_position):
12207 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12208 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12209 (Fnext_overlay_change, Fprevious_overlay_change)
12210 (mouse_face_overlay_overlaps, Foverlays_in):
12211 Use ptrdiff_t, not int, for sizes.
12212 (overlays_at, overlays_in): Check for size-calculation overflow.
12214 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12216 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12217 (x_session_initialize): Do not assume string length fits in int.
12219 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12220 This is unlikely, but can occur if DPI is outlandish.
12222 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12223 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12225 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12226 * xrdb.c (magic_file_p, search_magic_path):
12227 Omit last arg SUFFIX; it was always 0. All callers changed.
12228 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12230 * xfont.c (xfont_match): Avoid need for strlen.
12232 * xfns.c: Don't assume strlen fits in int.
12233 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12235 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12236 not unsigned long, as we prefer signed integers. All callers changed.
12237 Detect integer overflow in repeat count.
12238 (message_dolog): Don't assume print length fits in 39 bytes.
12239 (display_mode_element): Don't assume strlen fits in int.
12241 * termcap.c: Don't assume sizes fit in int and never overflow.
12242 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12243 (gobble_line): Check for size-calculation overflow.
12245 * minibuf.c (Fread_buffer):
12246 * lread.c (intern, intern_c_string):
12247 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12248 Don't assume string length fits in int.
12250 * keyboard.c (parse_tool_bar_item):
12251 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12253 * font.c: Don't assume string length fits in int.
12254 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12255 Use ptrdiff_t, not int.
12256 (font_intern_prop): Don't assume string length fits in int.
12257 Don't assume integer property fits in fixnum.
12258 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12260 * filelock.c: Fix some buffer overrun and integer overflow issues.
12261 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12262 Reformulate so as not to need the command string.
12263 Invoke gzip -cd rather than gunzip, as it's more portable.
12264 (lock_info_type, lock_file_1, lock_file):
12265 Don't assume pid_t and time_t fit in unsigned long.
12266 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12267 (current_lock_owner): Prefer signed type for sizes.
12268 Use memcpy, not strncpy, where memcpy is what is really wanted.
12269 Don't assume (via atoi) that time_t and pid_t fit in int.
12270 Check for time_t and/or pid_t out of range, e.g., via a network share.
12271 Don't alloca where an auto var works fine.
12273 * fileio.c: Fix some integer overflow issues.
12274 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12275 Don't assume string length fits in int.
12276 (directory_file_name): Don't assume string length fits in long.
12277 (make_temp_name): Don't assume pid fits in int, or that its print
12278 length is less than 20.
12280 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12282 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12284 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12286 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12287 We prefer signed integers, even for size calculations.
12289 * emacs.c: Don't assume string length fits in 'int'.
12290 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12291 (main): Don't invoke strlen when not needed.
12293 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12294 (XD_DEBUG_MESSAGE): Don't waste a byte.
12296 * callproc.c (getenv_internal_1, getenv_internal)
12297 (Fgetenv_internal):
12298 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12300 * lread.c (invalid_syntax): Omit length argument.
12301 All uses changed. This doesn't fix a bug, but it simplifies the
12302 code away from its former Hollerith-constant appearance, and it's
12303 one less 'int' to worry about when looking at integer-overflow issues.
12304 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12306 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12307 This didn't break anything, but it didn't help either.
12308 It's confusing to put a bogus integer in a place where the actual
12309 value does not matter.
12310 (LIST_END_P): Remove unused macro and its bogus comment.
12311 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12313 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12314 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12316 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12317 We prefer signed types, and the value cannot exceed the EMACS_INT
12318 range anyway (because otherwise the length would not be representable).
12319 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12320 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12321 This avoids a GCC warning when WIDE_EMACS_INT.
12323 * indent.c (sane_tab_width): New function.
12324 (current_column, scan_for_column, Findent_to, position_indentation)
12325 (compute_motion): Use it. This is just for clarity.
12326 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12328 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12330 * lisp.h (lint_assume): New macro.
12331 * composite.c (composition_gstring_put_cache):
12332 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12334 * editfns.c, insdel.c:
12335 Omit unnecessary forward decls, to simplify future changes.
12337 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12339 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12341 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12342 Use much-faster test for byte-length change.
12343 Don't assume string byte-length fits in 'int'.
12344 Check that character arg fits in 'int'.
12345 (mapcar1): Declare byte as byte, for clarity.
12347 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12349 * fns.c (concat): Catch string overflow earlier.
12350 Do not rely on integer wraparound.
12352 * dispextern.h (struct it.overlay_strings_charpos)
12353 (struct it.selective): Now EMACS_INT, not int.
12354 * xdisp.c (forward_to_next_line_start)
12355 (back_to_previous_visible_line_start)
12356 (reseat_at_next_visible_line_start, next_element_from_buffer):
12357 Don't arbitrarily truncate the value of 'selective' to int.
12359 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12361 * composite.c: Don't truncate sizes to 'int'.
12362 (composition_gstring_p, composition_reseat_it)
12363 (composition_adjust_point): Use EMACS_INT, not int.
12364 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12365 not EMACS_UINT, for indexes.
12367 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12369 * buffer.c: Include <verify.h>.
12370 (struct sortvec.priority, struct sortstr.priority):
12371 Now EMACS_INT, not int.
12372 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12373 (struct sortstr.size, record_overlay_string)
12374 (struct sortstrlist.size, struct sortlist.used):
12375 Don't truncate size to int.
12376 (record_overlay_string): Check for size-calculation overflow.
12377 (init_buffer_once): Check at compile-time, not run-time.
12379 2011-06-22 Jim Meyering <meyering@redhat.com>
12381 Don't leak an XBM-image-sized buffer
12382 * image.c (xbm_load): Free the image buffer after using it.
12384 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12387 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12388 that Sun C diagnosed.
12389 * fns.c (secure_hash): Fix pointer signedness issue.
12390 * intervals.c (static_offset_intervals): New function.
12391 (offset_intervals): Use it.
12393 2011-06-21 Leo Liu <sdl.web@gmail.com>
12396 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12399 * fns.c (secure_hash): Rename from crypto_hash_function and change
12400 the first arg to accept symbols.
12401 (Fsecure_hash): New primitive.
12402 (syms_of_fns): New symbols.
12404 2011-06-20 Deniz Dogan <deniz@dogan.se>
12406 * process.c (Fset_process_buffer): Clarify return value in
12409 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12411 * dispnew.c (add_window_display_history): Use BVAR.
12413 * xdisp.c (debug_method_add): Use BVAR.
12414 (check_window_end, dump_glyph_matrix, dump_glyph)
12415 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12417 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12420 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12421 check till after the cache is created in init_frame_faces.
12423 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12425 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12427 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12429 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12430 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12431 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12433 Improve buffer-overflow checking (Bug#8873).
12434 * fileio.c (Finsert_file_contents):
12435 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12436 Remove the old (too-loose) buffer overflow checks.
12437 They weren't needed, since make_gap checks for buffer overflow.
12438 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12439 The old code merely checked for Emacs fixnum overflow, and relied
12440 on undefined (wraparound) behavior. The new code avoids undefined
12441 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12443 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12444 Tune. Don't use wider integers than needed. Don't use alloca.
12445 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12447 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12449 * insdel.c, lisp.h (buffer_overflow): New function.
12450 (insert_from_buffer_1, replace_range, replace_range_2):
12451 * insdel.c (make_gap_larger):
12452 * editfns.c (Finsert_char):
12453 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12455 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12457 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12459 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12461 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12462 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12464 * fileio.c: Don't assume EMACS_INT fits in off_t.
12465 (emacs_lseek): New static function.
12466 (Finsert_file_contents, Fwrite_region): Use it.
12467 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12469 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12471 * fns.c: Don't overflow int when computing a list length.
12472 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12473 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12474 truncation on 64-bit hosts. Check for QUIT every
12475 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12476 faster and is responsive enough.
12477 (Flength): Report an error instead of overflowing an integer.
12478 (Fsafe_length): Return a float if the value is not representable
12479 as a fixnum. This shouldn't happen except in contrived situations.
12480 (Fnthcdr, Fsort): Don't assume list length fits in int.
12481 (Fcopy_sequence): Don't assume vector length fits in int.
12483 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12484 (header_size, word_size): New constants.
12485 (allocate_vectorlike): Don't check size overflow here.
12486 (allocate_vector): Check it here instead, since this is the only
12487 caller of allocate_vectorlike that could cause overflow.
12488 Check that the new vector's length is representable as a fixnum.
12490 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12491 The previous code was bogus. For example, next_almost_prime (32)
12492 returned 39, which is undesirable as it is a multiple of 3; and
12493 next_almost_prime (24) returned 25, which is a multiple of 5 so
12494 why was the code bothering to check for multiples of 7?
12496 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12498 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12500 Variadic C functions now count arguments with ptrdiff_t.
12501 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12502 Back then I didn't know that the Emacs coding style prefers signed int.
12503 Also, in the meantime I found a few more instances where arguments
12504 were being counted with int, which may truncate counts on 64-bit
12505 machines, or EMACS_INT, which may be unnecessarily wide.
12506 * lisp.h (struct Lisp_Subr.function.aMANY)
12507 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12508 Arg counts are now ptrdiff_t, not size_t.
12509 All variadic functions and their callers changed accordingly.
12510 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12511 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12512 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12513 * callint.c (Fcall_interactively): Check arg count for overflow,
12514 to avoid potential buffer overrun. Use signed char, not 'int',
12515 for 'varies' array, so that we needn't bother to check its size
12516 calculation for overflow.
12517 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12518 * eval.c (apply_lambda):
12519 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12520 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12521 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12523 * callint.c (Fcall_interactively): Don't use index var as event count.
12525 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12526 * mem-limits.h (SIZE): Remove; no longer used.
12528 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12530 Remove unnecessary casts.
12531 * xterm.c (x_term_init):
12532 * xfns.c (x_set_border_pixel):
12533 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12534 These aren't needed now that we assume ANSI C.
12536 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12537 It's more likely to cause problems (due to unsigned overflow)
12540 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12542 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12544 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12546 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12548 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12550 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12552 GLYPH_CODE_FACE returns EMACS_INT, not int.
12553 * dispextern.h (merge_faces):
12554 * xfaces.c (merge_faces):
12555 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12556 Don't assume EMACS_INT fits in int.
12558 * character.h (CHAR_VALID_P): Remove unused parameter.
12559 * fontset.c, lisp.h, xdisp.c: All uses changed.
12561 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12563 * fns.c (concat): Minor tuning based on overflow analysis.
12564 This doesn't fix any bugs. Use int to hold character, instead
12565 of constantly refetching from Emacs object. Use XFASTINT, not
12566 XINT, for value known to be a character. Don't bother comparing
12567 a single byte to 0400, as it's always less.
12569 * floatfns.c (Fexpt):
12570 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12572 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12575 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12577 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12578 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12579 incorrectly succeed when S was a string, because 4294967386 was
12580 truncated before it was used.
12582 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12583 Otherwise, an out-of-range integer could cause undefined behavior
12586 * composite.c: Use int, not EMACS_INT, for characters.
12587 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12588 EMACS_INT, for values that are known to be in character range.
12589 This doesn't fix any bugs but is the usual style inside Emacs and
12590 may generate better code on 32-bit machines.
12592 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12593 This is for reasons similar to the recent CHAR_STRING fix.
12594 * charset.c (Fencode_char): Check that character arg is actually
12595 a character. Pass an int to ENCODE_CHAR.
12596 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12597 wider than 'int', as a compile-time check to prevent future regressions
12600 * character.c (char_string): Remove unnecessary casts.
12602 Make sure a 64-bit char is never passed to CHAR_STRING.
12603 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12604 by silently ignoring the top 32 bits, allowing some values
12605 that were far too large to be valid characters.
12606 * character.h: Include <verify.h>.
12607 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12608 arguments are no wider than unsigned, as a compile-time check
12609 to prevent future regressions in this area.
12611 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12612 (Fsubst_char_in_region):
12614 * xdisp.c (decode_mode_spec_coding):
12615 Adjust to CHAR_STRING's new requirement.
12616 * editfns.c (Finsert_char, Fsubst_char_in_region):
12617 * fns.c (concat): Check that character args are actually
12618 characters. Without this test, these functions did the wrong
12619 thing with wildly out-of-range values on 64-bit hosts.
12621 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12622 These casts should not be needed on 32-bit hosts, either.
12623 * keyboard.c (read_char):
12624 * lread.c (Fload): Remove casts to unsigned.
12626 * lisp.h (UNSIGNED_CMP): New macro.
12627 This fixes comparison bugs on 64-bit hosts.
12628 (ASCII_CHAR_P): Use it.
12629 * casefiddle.c (casify_object):
12630 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
12631 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
12632 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
12633 * dispextern.h (FACE_FROM_ID):
12634 * keyboard.c (read_char): Use UNSIGNED_CMP.
12636 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
12637 not to EMACS_INT, to avoid GCC warning.
12639 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
12641 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
12642 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
12643 isn't needed on 32-bit machines.
12645 * buffer.c (Fgenerate_new_buffer_name):
12646 Use EMACS_INT for count, not int.
12647 (advance_to_char_boundary): Return EMACS_INT, not int.
12649 * data.c (Qcompiled_function): Now static.
12651 * window.c (window_body_lines): Now static.
12653 * image.c (gif_load): Rename local to avoid shadowing.
12655 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
12656 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
12657 * alloc.c (make_save_value): Integer argument is now of type
12658 ptrdiff_t, not int.
12659 (mark_object): Use ptrdiff_t, not int.
12660 * lisp.h (pD): New macro.
12661 * print.c (print_object): Use it.
12663 * alloc.c: Use EMACS_INT, not int, to count objects.
12664 (total_conses, total_markers, total_symbols, total_vector_size)
12665 (total_free_conses, total_free_markers, total_free_symbols)
12666 (total_free_floats, total_floats, total_free_intervals)
12667 (total_intervals, total_strings, total_free_strings):
12668 Now EMACS_INT, not int. All uses changed.
12669 (Fgarbage_collect): Compute overall total using a double, so that
12670 integer overflow is less likely to be a problem. Check for overflow
12671 when converting back to an integer.
12672 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
12673 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
12674 These were 'int' variables that could overflow on 64-bit hosts;
12675 they were never used, so remove them instead of repairing them.
12676 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
12677 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
12678 Previously, this ceilinged at INT_MAX, but that doesn't work on
12680 (allocate_pseudovector): Don't use EMACS_INT when int would do.
12682 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
12683 (allocate_vectorlike): Check for ptrdiff_t overflow.
12684 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
12685 when a (possibly-narrower) signed value would do just as well.
12686 We prefer using signed arithmetic, to avoid comparison confusion.
12688 * alloc.c: Catch some string size overflows that we were missing.
12689 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
12690 for convenience in STRING_BYTES_MAX.
12691 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
12692 The definition here is exact; the one in lisp.h was approximate.
12693 (allocate_string_data): Check for string overflow. This catches
12694 some instances we weren't catching before. Also, it catches
12695 size_t overflow on (unusual) hosts where SIZE_MAX <= min
12696 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
12697 and ptrdiff_t and EMACS_INT are both 64 bits.
12699 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
12700 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
12701 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
12703 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
12705 * alloc.c (Fmake_string): Check for out-of-range init.
12707 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
12709 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
12711 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
12713 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

12716 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
12717 (int_gtk_range_get_value): Move to the scroll bar part of the file.
12718 (style_changed_cb): Call update_theme_scrollbar_width and call
12719 x_set_scroll_bar_default_width and xg_frame_set_char_size for
12720 all frames (Bug#8505).
12721 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
12722 Call gtk_window_set_resizable if HAVE_GTK3.
12723 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
12724 and height if HAVE_GTK3 (Bug#8505).
12725 (scroll_bar_width_for_theme): New variable.
12726 (update_theme_scrollbar_width): New function.
12727 (xg_get_default_scrollbar_width): Move code to
12728 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
12729 (xg_initialize): Call update_theme_scrollbar_width.
12731 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
12733 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
12735 2011-06-12 Martin Rudalics <rudalics@gmx.at>
12737 * frame.c (make_frame): Call other_buffer_safely instead of
12740 * window.c (temp_output_buffer_show): Call display_buffer with
12741 second argument Vtemp_buffer_show_specifiers and reset latter
12742 immediately after the call.
12743 (Vtemp_buffer_show_specifiers): New variable.
12744 (auto_window_vscroll_p, next_screen_context_lines)
12745 (Vscroll_preserve_screen_position): Remove leading asterisks from

13309 value of a `display' property is a "replacing spec".
13310 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13311 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

13341 * gnutls.c: Use Emacs's memory allocators.
13342 Without this change, the gnutls library would invoke malloc etc.
13343 directly, which causes problems on non-SYNC_INPUT hosts, and which
13344 runs afoul of improving memory_full behavior. (Bug#8761)
13345 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13346 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13347 xfree instead of the default malloc, realloc, free.
13348 (Fgnutls_boot): No need to check for memory allocation failure,
13349 since xmalloc does that for us.

13378 need to be updated by these changes.
13379 * fns.c (make_hash_table, maybe_resize_hash_table):
13380 Check for integer overflow with large hash tables.
13381 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13382 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13383 (SXHASH_REDUCE): New macro.
13384 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13385 Use it instead of discarding useful hash info with large hash values.
13386 (sxhash_float): New function.
13387 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13388 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13389 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13390 Rewrite to use FIXNUM_BITS, as this simplifies things.
13391 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13392 Adjust signatures to match updated version of code.
13393 (consing_since_gc): Now EMACS_INT, since a single hash table can
13394 use more than INT_MAX bytes.

13443 Make it possible to run ./temacs.
13445 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13446 syms_of_callproc does the same thing. Remove test for
13447 "initialized", do it in the caller.
13448 * emacs.c (main): Avoid calling set_initial_environment when dumping.
13450 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
13452 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
13453 (read_minibuf): Use get_minibuffer.
13454 (syms_of_minibuf): Use DEFSYM.
13455 (Qmetadata): New var.
13456 * data.c (Qbuffer): Don't make it static.
13457 (syms_of_data): Use DEFSYM.
13459 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13461 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
13462 (CCL_CODE_MIN): New macro.
13464 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
13466 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
13468 * eval.c (Qdebug): Now static.
13469 * lisp.h (Qdebug): Remove decl. This reverts a part of the
13470 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
13471 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
13473 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13475 * image.c: Various fixes to ImageMagick code comments.
13476 (Fimagemagick_types): Doc fix.
13478 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13480 Minor fixes prompted by GCC 4.6.0 warnings.
13482 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13484 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13485 (x_clipboard_manager_save_all): Move extern decl to ...
13486 * xterm.h: ... here, so that it can be checked for consistency.
13488 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13490 * xselect.c (x_clipboard_manager_save_frame)
13491 (x_clipboard_manager_save_all): New functions.
13492 (Fx_clipboard_manager_save): Lisp function deleted.
13494 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13495 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13497 * xterm.h: Update prototype.
13499 2011-05-28 William Xu <william.xwl@gmail.com>
13501 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13502 exiting (Bug#8239).
13504 2011-05-28 Jim Meyering <meyering@redhat.com>
13506 Avoid a sign-extension bug in crypto_hash_function.
13507 * fns.c (to_uchar): Define.
13508 (crypto_hash_function): Use it to convert some newly-signed
13509 variables to unsigned, to avoid sign-extension bugs. For example,
13510 without this change, (md5 "truc") would evaluate to
13511 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13512 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13513 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13515 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13517 Integer overflow fixes.
13519 * dbusbind.c: Serial number integer overflow fixes.
13520 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13521 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13522 to hold a serial number that is too large for a fixnum.
13523 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13524 Check for serial numbers out of range. Decode any serial number
13525 that was so large that it became a float. (Bug#8722)
13527 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13528 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13529 Use XFASTINT rather than XUINT when numbers are nonnegative.
13530 (xd_append_arg, Fdbus_method_return_internal):
13531 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13532 arguments, check that Lisp number is nonnegative, rather than
13533 silently wrapping negative numbers around. (Bug#8722)
13534 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13537 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13539 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13541 ccl: Add integer overflow checks.
13542 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13543 (IN_INT_RANGE): New macros.
13544 (ccl_driver): Use them to check for integer overflow when
13545 decoding a CCL program. Many of the new checks are whether XINT (x)
13546 fits in int; it doesn't always, on 64-bit hosts. The new version
13547 doesn't catch all possible integer overflows, but it's an
13548 improvement. (Bug#8719)
13550 * alloc.c (make_event_array): Use XINT, not XUINT.
13551 There's no need for unsigned here.
13553 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13554 This follows up to the 2011-05-06 change that substituted uintptr_t
13555 for EMACS_INT. This case wasn't caught back then.
13557 Rework Fformat to avoid integer overflow issues.
13558 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13559 now (part of C89). Include <verify.h>.
13560 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13561 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13562 (Fformat): Avoid the prepass trying to compute sizes; it was only
13563 approximate and thus did not catch overflow reliably. Instead, walk
13564 through the format just once, formatting and computing sizes as we go,
13565 checking for integer overflow at every step, and allocating a larger
13566 buffer as needed. Keep track separately whether the format is
13567 multibyte. Keep only the most-recently calculated precision, rather
13568 than them all. Record whether each argument has been converted to
13569 string. Use EMACS_INT, not int, for byte and char and arg counts.
13570 Support field widths and precisions larger than INT_MAX. Avoid
13571 sprintf's undefined behavior with conversion specifications such as %#d
13572 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13573 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13574 formatting out-of-range floating point numbers with int
13575 formats. (Bug#8668)
13577 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13579 * data.c: Avoid integer truncation in expressions involving floats.
13580 * data.c: Include <intprops.h>.
13581 (arith_driver): When there's an integer overflow in an expression
13582 involving floating point, convert the integers to floating point
13583 so that the resulting value does not suffer from catastrophic
13584 integer truncation. For example, on a 64-bit host (* 4
13585 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13586 Do not rely on undefined behavior after integer overflow.
13588 merge count_size_as_multibyte, parse_str_to_multibyte
13589 * character.c, character.h (count_size_as_multibyte):
13590 Rename from parse_str_to_multibyte; all uses changed.
13591 Check for integer overflow.
13592 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13593 since it's now a duplicate of the other. This is more of
13594 a character than a buffer op, so better that it's in character.c.
13595 * fns.c, print.c: Adjust to above changes.
13597 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13599 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13601 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13603 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13604 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13605 (x_clipboard_manager_save): Now static.
13606 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13608 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13609 (crypto_hash_function): Now static.
13610 Fix pointer signedness problems. Avoid unnecessary initializations.
13612 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13614 * termhooks.h (Vselection_alist): Make it terminal-local.
13616 * terminal.c (create_terminal): Initialize it.
13618 * xselect.c: Support for clipboard managers.
13619 (Vselection_alist): Move to termhooks.h as terminal-local var.
13620 (LOCAL_SELECTION): New macro.
13621 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13622 (symbol_to_x_atom): Remove gratuitous arg.
13623 (x_handle_selection_request, lisp_data_to_selection_data)
13624 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13625 (x_own_selection, x_get_local_selection, x_convert_selection):
13626 New arg, specifying work frame. Use terminal-local Vselection_alist.
13627 (some_frame_on_display): Delete unused function.
13628 (Fx_own_selection_internal, Fx_get_selection_internal)
13629 (Fx_disown_selection_internal, Fx_selection_owner_p)
13630 (Fx_selection_exists_p): New optional frame arg.
13631 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13632 (x_handle_selection_clear): Don't treat other terminals with the
13633 same keyboard specially. Use the terminal-local Vselection_alist.
13634 (x_clear_frame_selections): Use Frun_hook_with_args.
13636 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13638 * xterm.h: Add support for those atoms.
13640 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13642 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13643 (converted_selections, conversion_fail_tag): New global variables.
13644 (x_selection_request_lisp_error): Free the above.
13645 (x_get_local_selection): Remove unnecessary code.
13646 (x_reply_selection_request): Args changed; handle arbitrary array
13647 of converted selections stored in converted_selections.
13648 Separate the XChangeProperty and SelectionNotify steps.
13649 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
13650 (x_convert_selection): New function.
13651 (x_handle_selection_event): Simplify.
13652 (x_get_foreign_selection): Don't ignore incoming requests while
13653 waiting for an answer; this will fail when we implement
13654 SAVE_TARGETS, and seems unnecessary anyway.
13655 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
13656 (Vx_sent_selection_functions): Doc fix.
13658 2011-05-26 Leo Liu <sdl.web@gmail.com>
13660 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
13662 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13664 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
13666 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
13667 for fringe update if it has periodic bitmap.
13668 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
13669 and fringe_bitmap_periodic_p.
13671 * fringe.c (get_fringe_bitmap_data): New function.
13672 (draw_fringe_bitmap_1, update_window_fringes): Use it.
13673 (update_window_fringes): Record periodicity of fringe bitmap in glyph
13674 row. Mark glyph row for fringe update if periodicity changed.
13676 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
13677 for fringe update unless it has periodic bitmap.
13679 2011-05-25 Kenichi Handa <handa@m17n.org>
13681 * xdisp.c (get_next_display_element): Set correct it->face_id for
13682 a static composition.
13684 2011-05-24 Leo Liu <sdl.web@gmail.com>
13687 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
13689 * fns.c (crypto_hash_function, Fsha1): New function.
13690 (Fmd5): Use crypto_hash_function.
13691 (syms_of_fns): Add Ssha1.
13693 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13695 * gnutls.c: Remove unused macros.
13696 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
13697 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
13698 Remove macros that are defined and never used.
13699 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
13701 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13703 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
13704 (Fx_get_selection_internal): Minor cleanup.
13705 (Fx_own_selection_internal): Rename arguments for consistency with
13708 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13710 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
13712 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13714 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
13716 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13718 * dispnew.c (scrolling_window): Don't exclude the case that the
13719 last enabled row in the desired matrix touches the bottom boundary.
13721 2011-05-21 Glenn Morris <rgm@gnu.org>
13723 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
13724 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
13725 and add some more files.
13727 2011-05-20 Eli Zaretskii <eliz@gnu.org>
13729 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
13730 report_file_error introduced by the change from 2011-05-07.
13732 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
13734 * systime.h (Time): Define only if emacs is defined.
13735 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
13736 where the include path doesn't have X11/X.h by default. See
13737 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
13739 2011-05-20 Kenichi Handa <handa@m17n.org>
13741 * composite.c (find_automatic_composition): Fix previous change.
13743 2011-05-20 Glenn Morris <rgm@gnu.org>
13745 * lisp.mk: New file, split from Makefile.in.
13746 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
13747 (shortlisp): Remove.
13748 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
13750 2011-05-19 Glenn Morris <rgm@gnu.org>
13752 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
13753 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
13754 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
13755 (lisp): Set the order to that of loadup.el.
13756 (shortlisp): Make it a copy of $lisp.
13757 (SOME_MACHINE_LISP): Remove.
13758 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
13759 Use just $shortlisp, not $SOME_MACHINE_LISP too.
13761 2011-05-18 Kenichi Handa <handa@m17n.org>
13763 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
13764 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
13765 (find_automatic_composition): Mostly rewrite for efficiency.
13767 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
13769 * makefile.w32-in: Update dependencies.
13771 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
13773 * menu.c: Include limits.h (fixes the MS-Windows build broken by
13774 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
13776 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
13778 Fix some integer overflow issues, such as string length overflow.
13780 * insdel.c (count_size_as_multibyte): Check for string overflow.
13782 * character.c (lisp_string_width): Check for string overflow.
13783 Use EMACS_INT, not int, for string indexes and lengths; in
13784 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
13785 the resulting string length overflows an EMACS_INT; instead,
13786 report a string overflow if no precision given. When checking for
13787 precision exhaustion, use a check that cannot possibly have
13788 integer overflow. (Bug#8675)
13789 * character.h (lisp_string_width): Adjust to new signature.
13791 * alloc.c (string_overflow): New function.
13792 (Fmake_string): Use it. This doesn't change behavior, but saves
13793 a few bytes and will simplify future changes.
13794 * character.c (string_escape_byte8): Likewise.
13795 * lisp.h (string_overflow): New decl.
13797 Fixups, following up to the user-interface timestamp change.
13798 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
13799 for UI timestamps, instead of unsigned long.
13800 * msdos.c (mouse_get_pos): Likewise.
13801 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
13802 * w32gui.h (Time): Define by including "systime.h" rather than by
13803 declaring it ourselves. (Bug#8664)
13805 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
13806 * image.c (clear_image_cache): Likewise.
13808 * term.c (term_mouse_position): Don't assume time_t wraparound.
13810 Be more systematic about user-interface timestamps.
13811 Before, the code sometimes used 'Time', sometimes 'unsigned long',
13812 and sometimes 'EMACS_UINT', to represent these timestamps.
13813 This change causes it to use 'Time' uniformly, as that's what X uses.
13814 This makes the code easier to follow, and makes it easier to catch
13815 integer overflow bugs such as Bug#8664.
13816 * frame.c (Fmouse_position, Fmouse_pixel_position):
13817 Use Time, not unsigned long, for user-interface timestamps.
13818 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
13819 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
13820 * keyboard.h (last_event_timestamp): Likewise.
13821 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
13822 * menu.h (xmenu_show): Likewise.
13823 * term.c (term_mouse_position): Likewise.
13824 * termhooks.h (struct input_event.timestamp): Likewise.
13825 (struct terminal.mouse_position_hook): Likewise.
13826 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
13827 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
13828 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
13829 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
13830 what it was before.
13831 * menu.h, termhooks.h: Include "systime.h", for Time.
13833 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
13834 Don't assume that the difference between two unsigned long values
13835 can fit into an integer. At this point, we know button_down_time
13836 <= event->timestamp, so the difference must be nonnegative, so
13837 there's no need to cast the result if double-click-time is
13838 nonnegative, as it should be; check that it's nonnegative, just in
13839 case. This bug is triggered when events are more than 2**31 ms
13840 apart (about 25 days). (Bug#8664)
13842 * xselect.c (last_event_timestamp): Remove duplicate decl.
13843 (x_own_selection): Remove needless cast to unsigned long.
13845 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
13846 that always fit in int. Use a sentinel instead of a counter, to
13847 avoid a temp and to allay GCC's concerns about possible int overflow.
13848 * frame.h (struct frame): Use int for menu_bar_items_used
13849 instead of EMACS_INT, since it always fits in int.
13851 * menu.c (grow_menu_items): Check for int overflow.
13853 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
13855 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
13856 Before, the code was not consistent. These values cannot exceed
13857 2**31 - 1 so there's no need to make them unsigned.
13858 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
13859 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
13860 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
13862 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
13864 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
13865 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
13866 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
13867 presumably because the widths might not match.
13869 * window.c (size_window): Avoid needless test at loop start.
13871 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
13873 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
13875 2011-05-12 Drew Adams <drew.adams@oracle.com>
13877 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
13879 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13881 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
13882 `width' to `bar_area_x' and `bar_area_width', respectively.
13883 (x_scroll_run): Take account of fringe background extension.
13885 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
13886 Rename local vars `left' and `width' to `bar_area_x' and
13887 `bar_area_width', respectively.
13888 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
13889 background extension.
13891 2011-05-10 Jim Meyering <meyering@redhat.com>
13893 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
13895 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
13897 * image.c (Finit_image_library): Return t for built-in image types,
13898 like pbm and xbm. (Bug#8640)
13900 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
13902 * w32menu.c (set_frame_menubar): Fix submenu allocation.
13904 2011-05-07 Eli Zaretskii <eliz@gnu.org>
13906 * w32console.c (Fset_screen_color): Doc fix.
13907 (Fget_screen_color): New function.
13908 (syms_of_ntterm): Defsubr it.
13910 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
13911 unlink the temporary file if Fcall_process didn't create it in the
13913 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
13914 child process will be redirected to a file specified with `:file'.
13915 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
13916 cue to call_process_cleanup not to close that handle.
13918 2011-05-07 Ben Key <bkey76@gmail.com>
13920 * makefile.w32-in: The bootstrap-temacs rule now makes use of
13921 one of two shell specific rules, either bootstrap-temacs-CMD or
13922 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
13923 to the previous implementation of the bootstrap-temacs rule.
13924 The bootstrap-temacs-CMD rule is similar to the previous
13925 implementation of the bootstrap-temacs rule except that it
13926 makes use of the ESC_CFLAGS variable instead of the CFLAGS
13929 These changes, along with some changes to nt/configure.bat,
13930 nt/gmake.defs, and nt/nmake.defs, are required to extend my
13931 earlier fix to add support for --cflags and --ldflags options
13932 that include quotes so that it works whether make uses cmd or
13935 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
13937 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
13938 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
13940 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
13941 a string. Handle both cases.
13942 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
13943 (Fdbus_register_method): Use Qinvalid_function.
13945 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
13947 * makefile.w32-in: Update dependencies.
13948 (LISP_H): Add inttypes.h and stdin.h.
13949 (PROCESS_H): Add unistd.h.
13951 2011-05-06 Eli Zaretskii <eliz@gnu.org>
13953 * lread.c: Include limits.h (fixes the MS-Windows build broken by
13954 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
13956 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
13958 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
13960 * term.c (vfatal): Remove stray call to va_end.
13961 It's not needed and the C Standard doesn't allow it here anyway.
13963 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
13964 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
13966 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
13969 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
13971 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13973 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
13975 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
13977 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
13979 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
13980 * charset.c (Fdefine_charset_internal): Don't initialize
13981 charset.code_space[15]. The value was garbage, on hosts with
13982 32-bit int (Bug#8600).
13984 * lread.c (read_integer): Be more consistent with string-to-number.
13985 Use string_to_number to do the actual conversion; this avoids
13986 rounding errors and fixes some other screwups. Without this fix,
13987 for example, #x1fffffffffffffff was misread as -2305843009213693952.
13988 (digit_to_number): Move earlier, for benefit of read_integer.
13989 Return -1 if the digit is out of range for the base, -2 if it is
13990 not a digit in any supported base. (Bug#8602)
13992 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13994 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13995 to match comment at start of function. This also removes a
13996 GCC warning about overflow in a 32+64-bit port.
13998 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14000 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14001 Reported by Stefan Monnier in
14002 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14003 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14004 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14006 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14007 (EMACS_UINTPTR): Likewise, with uintptr_t.
14009 * lisp.h: Prefer 64-bit EMACS_INT if available.
14010 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14011 on 32-bit hosts that have 64-bit int, so that they can access
14013 However, temporarily disable this change unless the temporary
14014 symbol WIDE_EMACS_INT is defined.
14016 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14018 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14019 This removes an assumption that EMACS_INT and long are the same
14020 width as pointers. The assumption is true for Emacs porting targets
14021 now, but we want to make other targets possible.
14022 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14023 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14024 In the rest of the code, change types of integers that hold casted
14025 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14026 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14027 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14028 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14029 No need to cast type when ORing.
14030 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14031 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14032 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14033 assume EMACS_INT is the same width as char *.
14034 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14035 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14036 Remove no-longer-needed casts.
14037 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14038 (xg_tool_bar_help_callback, xg_make_tool_item):
14039 Use EMACS_INTPTR to hold an integer
14040 that will be cast to void *; this can avoid a GCC warning
14041 if EMACS_INT is not the same width as void *.
14042 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14043 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14044 (current_message_1, set_message_1):
14045 Use a local to convert to proper width without a cast.
14046 * xmenu.c (dialog_selection_callback): Likewise.
14048 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14049 Also, don't assume VALBITS / RAND_BITS is less than 5,
14050 and don't rely on undefined behavior when shifting a 1 left into
14052 * lisp.h (get_random): Change signature to match.
14054 * lread.c (hash_string): Use size_t, not int, for hash computation.
14055 Normally we prefer signed values; but hashing is special, because
14056 it's better to use unsigned division on hash table sizes so that
14057 the remainder is nonnegative. Also, size_t is the natural width
14058 for hashing into memory. The previous code used 'int', which doesn't
14059 retain enough info to hash well into very large tables.
14060 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14062 * dbusbind.c: Don't possibly lose pointer info when converting.
14063 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14064 Use XPNTR rather than XHASH, so that the high-order bits of
14065 the pointer aren't lost when converting through void *.
14067 * eval.c (Fautoload): Don't double-shift a pointer.
14069 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14071 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14073 * gnutls.c (DEF_GNUTLS_FN):
14074 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14076 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14078 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14081 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14083 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14084 New version that can reserve upto 2GB of heap space.
14086 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14088 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

14092 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14093 `gnutls_certificate_set_x509_key_file'.
14095 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14097 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14098 Update dependencies.
14100 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14102 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14103 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14104 Remove unused parameter `fildes'.
14105 * process.c (read_process_output, send_process): Don't pass it.
14107 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14109 Fix previous change: the library cache is defined in w32.c.
14110 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14111 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14113 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14115 Implement dynamic loading of GnuTLS on Windows.
14117 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14118 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14119 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14122 * gnutls.c (Qgnutls_dll): Define.
14123 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14124 (gnutls_*): Declare function pointers.
14125 (init_gnutls_functions): New function to initialize function pointers.

14128 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14129 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14130 (emacs_gnutls_write, emacs_gnutls_read)
14131 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14132 (Fgnutls_available_p): New function.
14133 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14134 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14135 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14137 * image.c: Include w32.h.
14138 (Vimage_type_cache): Delete.
14139 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
14140 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
14141 (w32_delayed_load): Move to w32.c.
14143 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14145 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14146 (w32_delayed_load): Move from image.c. When loading a library, record
14147 its filename in the :loaded-from property of the library id.
14148 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14149 Initialize and staticpro them.
14150 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14152 * process.c: Include lisp.h before w32.h, not after.
14153 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14154 instead of gnutls_record_check_pending.
14156 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14158 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14160 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14161 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14164 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14166 * xterm.c (x_set_frame_alpha): Do not set property on anything
14167 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14169 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14171 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14173 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14175 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14183 (Qgnutls_bootprop_callbacks_verify): Make static.
14185 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
14187 * callproc.c: Indentation fixup.
14189 * sysdep.c (wait_for_termination_1): Make static.
14190 (wait_for_termination, interruptible_wait_for_termination):
14191 Move after wait_for_termination_1.
14193 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14195 * sysdep.c (interruptible_wait_for_termination): New function
14196 which is like wait_for_termination, but allows keyboard
14199 * callproc.c (Fcall_process): Add (:file "file") as an option for
14201 (Fcall_process_region): Ditto.
14203 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14205 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14206 rather than `XVECTOR (FOO)->size'.
14208 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14209 inttypes.h, as a gnulib replacement is used if it not available in
14212 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14214 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14215 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14216 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14218 * coding.c (coding_alloc_by_realloc): Error out if destination
14219 will grow beyond MOST_POSITIVE_FIXNUM.
14220 (decode_coding_emacs_mule): Abort if there isn't enough place in
14221 charbuf for the composition carryover bytes. Reserve an extra
14222 space for up to 2 characters produced in a loop.
14223 (decode_coding_iso_2022): Abort if there isn't enough place in
14224 charbuf for the composition carryover bytes.

14229 aborting when %lld or %lll format is passed.
14230 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14231 %llo or %llx format is passed. (Bug#8545)
14233 * window.c (window_scroll_line_based): Use a marker instead of
14234 simple variables to record original value of point. (Bug#7952)
14236 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14237 produced by %s or %c overflows available buffer space. (Bug#8545)
14239 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14241 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14242 (SIZE_MAX): Move defn after all includes, as they might #define it.
14244 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14246 * w32.c (init_environment): Warn about defaulting HOME to C:\.
14248 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14250 * keyboard.c (Qdelayed_warnings_hook): Define.
14251 (command_loop_1): Run `delayed-warnings-hook'
14252 if Vdelayed_warnings_list is non-nil.

14254 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
14256 2011-04-28 Eli Zaretskii <eliz@gnu.org>
14258 * doprnt.c (doprnt): Don't return value smaller than the buffer
14259 size if the message was truncated. (Bug#8545).
14261 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14263 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
14264 (Fx_window_property): #if-0 the whole functions, not just the bodies.
14266 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14268 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
14270 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14272 * makefile.w32-in: Update dependencies.
14274 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14276 Improve `doprnt' and its usage. (Bug#8545)
14277 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14278 `format_end'. Remove support for %l as a conversion specifier.
14279 Don't use xrealloc. Improve diagnostics when the %l size modifier
14280 is used. Update the commentary.
14282 * eval.c (verror): Simplify calculation of size_t.
14284 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14287 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14289 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14292 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14294 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14295 This makes this file independent of the recent pseudovector change.
14297 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14299 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14301 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14302 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14303 Remove unused local.
14304 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14306 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14307 GCC 4.6.0 optimizes based on type-based alias analysis.
14308 For example, if b is of type struct buffer * and v of type struct
14309 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14310 != &v->size, and therefore "v->size = 1; b->size = 2; return
14311 v->size;" must therefore return 1. This assumption is incorrect
14312 for Emacs, since it type-puns struct Lisp_Vector * with many other
14313 types. To fix this problem, this patch adds a new type struct
14314 vectorlike_header that documents the constraints on layout of vectors
14315 and pseudovectors, and helps optimizing compilers not get fooled
14316 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14317 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14318 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14320 (XSETPVECTYPE): Rewrite in terms of new macro.
14321 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14322 This is a bit clearer, and further avoids the possibility of
14323 undesirable aliasing.
14324 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14325 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14326 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14327 since Lisp_Subr is a special case (no "next" field).
14328 (ASIZE): Now uses header.size rather than size.
14329 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14330 to avoid the hassle of writing XVECTOR (foo)->header.size.
14331 (struct vectorlike_header): New type.
14332 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14333 object, to help avoid aliasing.
14334 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14335 (SUBRP): Likewise, since Lisp_Subr is a special case.
14336 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14337 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14338 (struct Lisp_Hash_Table): Combine first two members into a single
14339 struct vectorlike_header member. All uses of "size" and "next" members
14340 changed to be "header.size" and "header.next".
14341 * buffer.h (struct buffer): Likewise.
14342 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14343 * frame.h (struct frame): Likewise.
14344 * process.h (struct Lisp_Process): Likewise.
14345 * termhooks.h (struct terminal): Likewise.
14346 * window.c (struct save_window_data, struct saved_window): Likewise.
14347 * window.h (struct window): Likewise.
14348 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14349 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14350 * buffer.c (init_buffer_once): Likewise.
14351 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14353 * process.c (Fformat_network_address): Use local var for size,
14356 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14358 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14359 * data.c (atof): Remove decl; no longer used or needed.
14360 (digit_to_number): Move to lread.c.
14361 (Fstring_to_number): Use new string_to_number function, to be
14362 consistent with how the Lisp reader treats infinities and NaNs.
14363 Do not assume that floating-point numbers represent EMACS_INT
14364 without losing information; this is not true on most 64-bit hosts.
14365 Avoid double-rounding errors, by insisting on integers when
14366 parsing non-base-10 numbers, as the documentation specifies.
14367 * lisp.h (string_to_number): New decl, replacing ...
14368 (isfloat_string): Remove.
14369 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14370 (read1): Do not accept +. and -. as integers; this
14371 appears to have been a coding error. Similarly, do not accept
14372 strings like +-1e0 as floating point numbers. Do not report
14373 overflow for integer overflows unless the base is not 10 which
14374 means we have no simple and reliable way to continue.
14375 Break out the floating-point parsing into a new
14376 function string_to_number, so that Fstring_to_number parses
14377 floating point numbers consistently with the Lisp reader.
14378 (digit_to_number): Move here from data.c. Make it static inline.
14379 (E_CHAR, EXP_INT): Remove, replacing with ...
14380 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14381 (string_to_number): New function, replacing isfloat_string.
14382 This function checks for valid syntax and produces the resulting
14383 Lisp float number too. Rework it so that string-to-number
14384 no longer mishandles examples like "1.0e+". Use strtoumax,
14385 so that overflow for non-base-10 numbers is reported only when
14386 there's no portable and simple way to convert to floating point.
14388 * textprop.c (set_text_properties_1): Rewrite for clarity,
14389 and to avoid GCC warning about integer overflow.
14391 * intervals.h (struct interval): Use EMACS_INT for members
14392 where EMACS_UINT might cause problems. See
14393 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14394 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14395 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14397 (offset_intervals): Tell GCC not to worry about length overflow
14398 when negating a negative length.
14400 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14401 (overrun_check_free): Likewise.
14403 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14404 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14407 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14408 (gnutls_make_error): Rename local to avoid shadowing.
14409 (gnutls_emacs_global_deinit): ifdef out; not used.
14410 (Fgnutls_boot): Use const for pointer to readonly storage.
14411 Comment out unused local. Fix pointer signedness problems.
14413 * lread.c (openp): Don't stuff size_t into an 'int'.
14414 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14415 about possible signed overflow.
14417 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14418 (GDK_KEY_g): Don't define if already defined.
14419 (xg_prepare_tooltip): Avoid pointer signedness problem.
14420 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14422 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14423 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14425 * xfns.c (Fx_window_property): Simplify a bit,
14426 to make a bit faster and to avoid GCC 4.6.0 warning.
14427 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14429 * fns.c (internal_equal): Don't assume size_t fits in int.
14431 * alloc.c (compact_small_strings): Tighten assertion a little.
14433 Replace pEd with more-general pI, and fix some printf arg casts.
14434 * lisp.h (pI): New macro, generalizing old pEd macro to other
14435 conversion specifiers. For example, use "...%"pI"d..." rather
14436 than "...%"pEd"...".
14437 (pEd): Remove. All uses replaced with similar uses of pI.
14438 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14439 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14440 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14441 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14442 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14443 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14444 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14446 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14447 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14448 * print.c (safe_debug_print, print_object): Likewise.
14449 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14451 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14452 avoiding the 0 flag, which is not portable.
14453 * process.c (Fmake_network_process): Use pI to avoid cast.
14454 * region-cache.c (pp_cache): Likewise.
14455 * xdisp.c (decode_mode_spec): Likewise.
14456 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14457 behavior on 64-bit hosts with printf arg.
14458 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14459 (x_stop_queuing_selection_requests): Likewise.
14460 (x_get_window_property): Don't truncate byte count to an 'int'
14463 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14464 here, since it parses constructs like leading '-' and spaces,
14465 which are not wanted; and it overflows with large numbers.
14466 Instead, simply match F[0-9]+, which is what is wanted anyway.
14468 * alloc.c: Remove unportable assumptions about struct layout.
14469 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14470 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14471 (allocate_vectorlike, make_pure_vector): Use the new macros,
14472 plus offsetof, to remove unportable assumptions about struct layout.
14473 These assumptions hold on all porting targets that I know of, but
14474 they are not guaranteed, they're easy to remove, and removing them
14475 makes further changes easier.
14477 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14478 This doesn't fix a bug but makes the code clearer.
14479 (string_overrun_cookie): Now const. Use initializers that
14480 don't formally overflow signed char, to avoid warnings.
14481 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14482 can cause Emacs to crash when string overrun checking is enabled.
14483 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14484 multiple of sizeof (EMACS_INT); it need not be, if
14485 alignof(EMACS_INT) < sizeof (EMACS_INT).
14486 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14488 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14495 supposed to be handshaking. (Bug#8556)
14496 Reported by Paul Eggert <eggert@cs.ucla.edu>.
14498 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
14500 * lisp.h (Qdebug): List symbol.
14501 * eval.c (Qdebug): Restore global linkage.

14503 (handle_user_signal): Break into debugger when debug-on-event
14504 matches the current signal symbol.
14506 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
14508 * alloc.c (check_sblock, check_string_bytes)
14509 (check_string_free_list): Convert to standard C.
14511 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14513 * w32.c (emacs_gnutls_push): Fix typo.
14515 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14517 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14518 "cast to pointer from integer of different size".
14520 Improve doprnt and its use in verror. (Bug#8545)
14521 * doprnt.c (doprnt): Document the set of format control sequences
14522 supported by the function. Use SAFE_ALLOCA instead of always
14525 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14526 is one byte too soon. Don't use xrealloc; instead xfree and
14529 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14531 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14534 * gnutls.c: Renamed global_initialized to
14535 gnutls_global_initialized. Added internals for the
14536 :verify-hostname-error, :verify-error, and :verify-flags
14537 parameters of `gnutls-boot' and documented those parameters in the
14538 docstring. Start callback support.
14539 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14540 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14541 on error. Return error code.
14542 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
14543 (emacs_gnutls_read): Likewise.
14544 (Fgnutls_boot): Return handshake error code.
14545 (emacs_gnutls_handle_error): New function.
14546 (wsaerror_to_errno): Likewise.

14601 changes in globals.h immediately force recompilation.
14602 (TAGS): Depend on $(CURDIR)/m/intel386.h and
14603 $(CURDIR)/s/ms-w32.h.

14608 <char-direction-table>: Deleted.
14610 2011-04-23 Eli Zaretskii <eliz@gnu.org>
14612 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
14613 * doprnt.c: Include limits.h.
14614 (SIZE_MAX): New macro.
14615 (doprnt): Return a size_t value. 2nd arg is now size_t.
14616 Many local variables are now size_t instead of int or unsigned.
14617 Improve overflow protection. Support `l' modifier for integer
14618 conversions. Support %l conversion. Don't assume an EMACS_INT
14619 argument for integer conversions and for %c.
14621 * lisp.h (doprnt): Restore prototype.
14623 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
14624 $(SRC)/character.h.
14626 * Makefile.in (base_obj): Add back doprnt.o.
14628 * deps.mk (doprnt.o): Add back prerequisites.
14629 (callint.o): Depend on character.h.
14631 * eval.c (internal_lisp_condition_case): Include the handler
14632 representation in the error message.
14633 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
14634 when breaking from the loop.
14636 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
14638 * callint.c (Fcall_interactively): When displaying error message
14639 about invalid control letter, pass the character's codepoint, not
14640 a pointer to its multibyte form. Improve display of the character
14641 in octal and display also its hex code.
14643 * character.c (char_string): Use %x to display the (unsigned)
14644 codepoint of an invalid character, to avoid displaying a bogus
14647 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
14648 `error', not SYMBOL_NAME itself.
14650 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
14651 character arguments to `error'.
14653 * charset.c (check_iso_charset_parameter): Fix incorrect argument
14654 to `error' in error message about FINAL_CHAR argument. Make sure
14655 FINAL_CHAR is a character, and use %c when it is passed as
14656 argument to `error'.

14720 Define only if needed.
14722 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
14723 by pacifying GCC about it. Maybe it's time to retire it?
14724 * xfaces.c (USG, __TIMEVAL__): Likewise.
14726 * dispextern.h (struct redisplay_interface): Rename param
14727 to avoid shadowing.
14728 * termhooks.h (struct terminal): Likewise.
14729 * xterm.c (xembed_send_message): Likewise.
14731 * insdel.c (make_gap_smaller): Define only if
14732 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
14734 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
14737 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
14738 so that we aren't warned about unused symbols.
14740 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
14742 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
14744 * xfns.c (x_real_positions): Mark locals as initialized.
14746 * xmenu.c (xmenu_show): Don't use uninitialized vars.
14748 * xterm.c: Fix problems found by static analysis with other toolkits.
14749 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
14750 (x_dispatch_event): Declare static if USE_GTK, and
14751 define if USE_GTK || USE_X_TOOLKIT.
14752 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
14753 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
14754 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
14755 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
14757 * xmenu.c (menu_help_callback): Pointer type fixes.
14758 Use const pointers when pointing at readonly data. Avoid pointer
14759 signedness clashes.
14760 (FALSE): Remove unused macro.

15202 * buffer.c (buffer_count): Remove unused var.
15204 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
15205 so that it's not optimized away.
15206 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
15207 * dispextern.h (bidi_dump_cached_states): Remove, since it's
15208 exported only to the debugger.
15210 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
15211 * atimer.h (run_all_atimers): Remove; not exported.
15213 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
15214 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
15215 was inaccessible from Lisp.
15216 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
15217 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
15219 alloc.c: Import and export fewer symbols, and remove unused items.
15220 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
15222 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
15223 it's not optimized away by whole-program optimization.
15224 (message_enable_multibyte, free_misc): Remove.
15225 (catchlist, handlerlist, mark_backtrace):
15226 Declare only if BYTE_MARK_STACK.
15227 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
15228 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
15229 (message_enable_multibyte): Remove decl.
15230 (free_misc, interval_free_list, float_block, float_block_index):
15231 (n_float_blocks, float_free_list, cons_block, cons_block_index):
15232 (cons_free_list, last_marked_index):
15234 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
15235 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15236 (mark_backtrace): Define only if BYTE_MARK_STACK.
15237 * xdisp.c (message_enable_multibyte): Now static.
15239 Declare Lisp_Object Q* variables to be 'static' if not exported.
15240 This makes it easier for human readers (and static analyzers)
15241 to see whether these variables are used from other modules.
15242 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15243 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15244 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
15245 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
15246 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
15247 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15248 * xmenu.c, xselect.c:
15249 Declare Q* vars static if they are not used in other modules.
15250 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15251 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15252 Remove decls of unexported vars.
15253 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15255 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15257 Make Emacs functions such as Fatom 'static' by default.
15258 This makes it easier for human readers (and static analyzers)
15259 to see whether these functions can be called from other modules.
15260 DEFUN now defines a static function. To make the function external
15261 so that it can be used in other C modules, use the new macro DEFUE.
15262 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15263 (Finit_image_library):
15264 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15265 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15266 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15267 Remove decls, since these functions are now static.
15268 (Funintern, Fget_internal_run_time): New decls, since these functions
15269 were already external.
15271 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15272 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15273 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15274 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15275 * keyboard.c, keymap.c, lread.c:
15276 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15277 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15278 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15279 Mark functions with DEFUE instead of DEFUN,
15280 if they are used in other modules.
15281 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15282 decls for now-static functions.
15283 * buffer.h (Fdelete_overlay): Remove decl.
15284 * callproc.c (Fgetenv_internal): Mark as internal.
15285 * composite.c (Fremove_list_of_text_properties): Remove decl.

15289 * doc.c (Fdocumntation_property): New forward static decl.
15290 * eval.c (Ffetch_bytecode): New forward static decl.
15291 (Funintern): Remove extern decl; now in .h file where it belongs.
15292 * fileio.c (Fmake_symbolic_link): New forward static decl.
15293 * image.c (Finit_image_library): New forward static decl.
15294 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15295 * intervals.h (Fprevious_property_change):
15296 (Fremove_list_of_text_properties): Remove decls.
15297 * keyboard.c (Fthis_command_keys): Remove decl.
15298 (Fcommand_execute): New forward static decl.
15299 * keymap.c (Flookup_key): New forward static decl.
15300 (Fcopy_keymap): Now static.
15301 * keymap.h (Flookup_key): Remove decl.
15302 * process.c (Fget_process): New forward static decl.
15303 (Fprocess_datagram_address): Mark as internal.
15304 * syntax.c (Fsyntax_table_p): New forward static decl.
15305 (skip_chars): Remove duplicate decl.

15314 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15316 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15319 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15321 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15322 when at ZV. (Bug#8487)
15324 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15326 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15328 * keyboard.c (parse_tool_bar_item): Likewise.
15329 * sound.c (sound_cleanup, alsa_close): Likewise.
15330 * termcap.c (tgetent): Likewise.
15331 * xfns.c (x_default_font_parameter): Likewise.
15332 * xsettings.c (read_and_apply_settings): Likewise.
15334 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15335 (overrun_check_free): Protoize.
15337 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15339 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15340 since callers should never pass a negative size.
15341 Change the signature to match that of plain 'read' and 'write'; see
15342 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15343 * lisp.h: Update prototypes of emacs_write and emacs_read.
15345 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15347 * xdisp.c (redisplay_window): Don't try to determine the character
15348 position of the scroll margin if the window start point w->startp
15349 is outside the buffer's accessible region. (Bug#8468)
15351 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15353 Fix write-region and its subroutines for buffers > 2GB.
15354 * fileio.c (a_write, e_write): Modify declaration of arguments and
15355 local variables to support buffers larger than 2GB.
15356 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15358 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15359 argument, local variables, and return value.
15361 * lisp.h: Update prototypes of emacs_write and emacs_read.
15363 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15365 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15367 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15369 Fix more problems found by GCC 4.6.0's static checks.
15371 * xdisp.c (vmessage): Use a better test for character truncation.
15373 * charset.c (load_charset_map): <, not <=, for optimization,
15374 and to avoid potential problems with integer overflow.
15375 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15376 * casetab.c (set_identity, shuffle): Likewise.
15377 * editfns.c (Fformat): Likewise.
15378 * syntax.c (skip_chars): Likewise.
15380 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15381 This also lets GCC 4.6.0 generate slightly better loop code.
15383 * callint.c (Fcall_interactively): <, not <=, for optimization.
15384 (Fcall_interactively): Count the number of arguments produced,
15385 not the number of arguments given. This is simpler and lets GCC
15386 4.6.0 generate slightly better code.
15388 * ftfont.c: Distingish more carefully between FcChar8 and char.
15389 The previous code passed unsigned char * to a functions like
15390 strlen and xstrcasecmp that expect char *, which does not
15391 conform to the C standard.
15392 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15393 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15394 char * when the C standard requires it.
15396 * keyboard.c (read_char): Remove unused var.
15398 * eval.c: Port to Windows vsnprintf (Bug#8435).
15399 Include <limits.h>.
15400 (SIZE_MAX): Define if the headers do not.
15401 (verror): Do not give up if vsnprintf returns a negative count.
15402 Instead, grow the buffer. This ports to Windows vsnprintf, which
15403 does not conform to C99. Problem reported by Eli Zaretskii.
15404 Also, simplify the allocation scheme, by avoiding the need for
15405 calling realloc, and removing the ALLOCATED variable.
15407 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15409 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15410 But keep the doprint source code for now, as we might revamp it
15411 and use it again (Bug#8435).
15412 * lisp.h (doprnt): Remove.
15413 * Makefile.in (base_obj): Remove doprnt.o.
15414 * deps.mk (doprnt.o): Remove.
15416 error: Print 32- and 64-bit integers portably (Bug#8435).
15417 Without this change, on typical 64-bit hosts error ("...%d...", N)
15418 was used to print both 32- and 64-bit integers N, which relied on
15419 undefined behavior.
15420 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15421 * lisp.h (error, verror): Mark as printf-like functions.
15422 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15423 Report overflow in size calculations when allocating printf buffer.
15424 Do not truncate output string at its first null byte.
15425 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15426 Truncate the output at a character boundary, since vsnprintf does not
15428 * charset.c (check_iso_charset_parameter): Convert internal
15429 character to string before calling 'error', since %c now has the
15431 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15432 overflow when computing char to be passed to 'error'. Do not
15433 pass Lisp_Object to 'error'; pass the integer instead.
15434 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15435 formatted with plain %d.
15437 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15439 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15441 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15443 * xterm.c (x_catch_errors): Remove duplicate declaration.
15445 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15447 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15449 2011-04-10 Jim Meyering <meyering@redhat.com>
15451 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15452 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15453 return ssize_t not "int", and use size_t as the buffer length.
15454 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15455 * gnutls.h: Update declarations.
15456 * process.c (read_process_output): Use ssize_t, to match.
15457 (send_process): Likewise.
15459 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15461 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15463 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15465 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15466 Use unsigned char, to match FcChar8 type definition.
15468 * xterm.c (handle_one_xevent):
15469 * xmenu.c (create_and_show_popup_menu):
15470 * xselect.c (x_decline_selection_request)
15471 (x_reply_selection_request): Avoid type-punned deref of X events.
15473 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15475 Fix some uses of `int' instead of EMACS_INT.
15476 * search.c (string_match_1, fast_string_match)
15477 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15478 (scan_buffer, find_next_newline_no_quit)
15479 (find_before_next_newline, search_command, Freplace_match)
15480 (Fmatch_data): Make some `int' variables be EMACS_INT.
15482 * xdisp.c (display_count_lines): 3rd argument and return value now
15483 EMACS_INT. All callers changed.
15484 (pint2hrstr): Last argument is now EMACS_INT.
15486 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15487 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15488 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15489 (decode_coding_utf_16, decode_coding_emacs_mule)
15490 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15491 (decode_coding_ccl, decode_coding_charset)
15492 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15493 (decode_coding_iso_2022, decode_coding_emacs_mule)
15494 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15495 <char_offset, last_offset>: Declare EMACS_INT.

15499 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15500 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15502 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15503 (encode_invocation_designation): Last argument P_NCHARS is now
15505 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15506 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15508 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15511 * ccl.c (Fccl_execute_on_string): Declare some variables
15514 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15516 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15518 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15520 * process.c (Fformat_network_address): Doc fix.
15522 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15524 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15526 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15528 * keyboard.c (read_char): Call Lisp function help-form-show,
15529 instead of using internal_with_output_to_temp_buffer.
15530 (Qhelp_form_show): New var.
15531 (syms_of_keyboard): Use DEFSYM macro.
15533 * print.c (internal_with_output_to_temp_buffer): Function deleted.

15540 (list_processes_1): Delete.
15542 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15544 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15546 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15548 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15550 Fix more problems found by GCC 4.6.0's static checks.
15552 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15554 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15556 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15558 * xdisp.c (vmessage): Mark as a printf-like function.
15560 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15562 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15564 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15565 printf-like functions.

15567 to system-supplied API.
15569 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15571 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15572 This avoids several warnings with gcc -Wstrict-overflow.
15573 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15574 directly, rather than having caller test rule sign. This avoids
15575 some unnecessary tests.
15576 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15577 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15578 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15580 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15581 (xfont_open): Avoid unnecessary tests.
15583 * composite.c (composition_gstring_put_cache): Use unsigned integer.

15592 by using the new macro.
15594 * textprop.c (set_text_properties_1): Change while to do-while,
15595 since the condition is always true at first.
15597 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15598 (interval_deletion_adjustment): Return unsigned value.
15601 * process.c (list_processes_1, create_pty, read_process_output):

15617 * print.c (print_error_message): Avoid int overflow.
15619 * font.c (font_list_entities): Redo for clarity,
15620 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15622 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15623 (font_score): Avoid potential overflow in diff calculation.
15625 * fns.c (substring_both): Remove var that is set but not used.
15626 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15628 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15630 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15631 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15632 can always succeed if overflow has undefined behavior.
15634 * search.c (boyer_moore, wordify): Remove vars set but not used.
15635 (wordify): Omit three unnecessary tests.
15637 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15638 All callers changed. This avoids the need for an unused var.
15640 * casefiddle.c (casify_region): Remove var that is set but not used.
15642 * dired.c (file_name_completion): Remove var that is set but not used.
15644 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
15646 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
15647 (Finsert_file_contents): Remove unnecessary code checking fd.
15649 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
15650 Check for integer overflow on size calculations.
15652 * buffer.c (Fprevious_overlay_change): Remove var that is set
15655 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
15656 Remove vars that are set but not used.
15657 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
15658 (timer_check_2): Mark vars as initialized.
15660 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
15662 * image.c (lookup_image): Remove var that is set but not used.
15663 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
15665 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
15666 that are set but not used.
15668 * xfns.c (make_invisible_cursor): Don't return garbage
15669 if XCreateBitmapFromData fails (Bug#8410).
15671 * xselect.c (x_get_local_selection, x_handle_property_notify):
15672 Remove vars that are set but not used.
15674 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
15675 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
15677 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
15678 Remove var that is set but not used.
15679 (scroll_bar_windows_size): Now size_t, not int.
15680 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
15681 Check for overflow.
15683 * xfaces.c (realize_named_face): Remove vars that are set but not used.
15684 (map_tty_color) [!defined MSDOS]: Likewise.
15686 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
15688 * coding.c: Remove vars that are set but not used.
15689 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
15690 All callers changed.
15691 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
15692 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
15693 (decode_coding_charset): Remove vars that are set but not used.
15695 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
15696 that is set but not used.
15698 * print.c (print_object): Remove var that is set but not used.
15700 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
15701 The gnulib version avoids calling malloc in the usual case,
15702 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
15703 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
15704 * filelock.c (current_lock_owner): Likewise.
15705 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
15706 * sysdep.c: Include allocator.h, careadlinkat.h.
15707 (emacs_no_realloc_allocator): New static constant.
15708 (emacs_readlink): New function.
15709 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
15710 ../lib/careadlinkat.h.
15712 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
15714 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
15715 first non-nil return value).

15726 (get_char_face_and_encoding): Remove parameter `multibyte_p',
15727 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

15729 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
15730 and thereabouts. All callers changed.
15731 (get_per_char_metric): Remove parameter `f', unused since
15732 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
15734 2011-04-02 Jim Meyering <meyering@redhat.com>
15736 do not dereference NULL upon failed strdup
15737 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
15738 (ns_get_family): Likewise.
15740 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
15742 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
15744 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
15746 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
15749 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
15751 Add lexical binding.
15753 * window.c (Ftemp_output_buffer_show): New fun.
15754 (Fsave_window_excursion):
15755 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
15757 * lread.c (lisp_file_lexically_bound_p): New function.
15758 (Fload): Bind Qlexical_binding.
15759 (readevalloop): Remove `evalfun' arg.
15760 Bind Qinternal_interpreter_environment.
15761 (Feval_buffer): Bind Qlexical_binding.
15762 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
15764 (syms_of_lread): Declare `lexical-binding'.
15766 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
15768 * keyboard.c (eval_dyn): New fun.
15769 (menu_item_eval_property): Use it.
15771 * image.c (parse_image_spec): Use Ffunctionp.
15773 * fns.c (concat, mapcar1): Accept byte-code-functions.
15775 * eval.c (Fsetq): Handle lexical vars.
15776 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
15777 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
15778 (FletX, Flet): Obey lexical binding.
15779 (Fcommandp): Handle closures.
15780 (Feval): New `lexical' arg.
15781 (eval_sub): New function extracted from Feval. Use it almost
15782 everywhere where Feval was used. Look up vars in lexical env.
15784 (Ffunctionp): Move from subr.el.
15785 (Ffuncall): Handle closures.
15786 (apply_lambda): Remove `eval_flags'.
15787 (funcall_lambda): Handle closures and new byte-code-functions.
15788 (Fspecial_variable_p): New function.
15789 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
15790 but without exporting it to Lisp.
15792 * doc.c (Fdocumentation, store_function_docstring):
15793 * data.c (Finteractive_form): Handle closures.
15795 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
15798 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
15800 (exec_byte_code): New function extracted from Fbyte_code to handle new
15801 calling convention for byte-code-functions. Add new byte-codes.
15803 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
15805 * alloc.c (Fmake_symbol): Init new `declared_special' field.
15807 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
15809 * xdisp.c (redisplay_internal): Fix prototype.
15811 2011-03-31 Eli Zaretskii <eliz@gnu.org>
15813 * xdisp.c (SCROLL_LIMIT): New macro.
15814 (try_scrolling): Use it when setting scroll_limit.
15815 Limit scrolling to 100 screen lines.
15816 (redisplay_window): Even when falling back on "recentering",
15817 position point in the window according to scroll-conservatively,
15818 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
15820 (try_scrolling): When point is above the window, allow searching
15821 as far as scroll_max, or one screenful, to compute vertical
15822 distance from PT to the scroll margin position. This prevents
15823 try_scrolling from unnecessarily failing when
15824 scroll-conservatively is set to a value slightly larger than the
15825 window height. Clean up the case of PT below the margin at bottom
15826 of window: scroll_max can no longer be INT_MAX. When aggressive
15827 scrolling is in use, don't let point enter the opposite scroll
15828 margin as result of the scroll.
15829 (syms_of_xdisp) <scroll-conservatively>: Document the
15830 threshold of 100 lines for never-recentering scrolling.
15832 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

15837 (message_log_check_duplicate): Remove parameters `prev_bol' and
15838 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
15839 (redisplay_internal): Remove parameter `preserve_echo_area',
15840 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
15842 * indent.c (Fvertical_motion):
15843 * window.c (window_scroll_pixel_based, Frecenter):
15844 Don't pass `need_y_p' to `move_it_by_lines'.
15846 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
15848 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
15849 steal a few bits to be more compact.
15850 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
15851 Remove unneeded casts.
15853 * bytecode.c (Fbyte_code): CAR and CDR can GC.
15855 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
15857 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
15858 binding" message (bug#7967).
15860 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
15862 Fix more problems found by GCC 4.6.0's static checks.
15864 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
15865 Remove unused local var.
15867 * editfns.c (Fmessage_box): Remove unused local var.
15869 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
15870 (note_mode_line_or_margin_highlight, note_mouse_highlight):
15871 Omit unused local vars.
15872 * window.c (shrink_windows): Omit unused local var.
15873 * menu.c (digest_single_submenu): Omit unused local var.
15874 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
15875 Omit unused local var.
15877 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
15878 Don't assume string length fits in int.
15879 (keyremap_step, read_key_sequence): Use size_t for sizes.
15880 (read_key_sequence): Don't check last_real_key_start redundantly.
15882 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
15883 instead of alloca (Bug#8344).
15885 * eval.c (Fbacktrace): Don't assume nargs fits in int.
15886 (Fbacktrace_frame): Don't assume nframes fits in int.
15888 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

15893 * term.c (produce_glyphless_glyph): Remove unnecessary test.
15895 * cm.c (calccost): Turn while-do into do-while, for clarity.
15897 * keyboard.c (syms_of_keyboard): Use the same style as later
15898 in this function when indexing through an array. This also
15899 works around GCC bug 48267.
15901 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
15903 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
15905 * chartab.c (sub_char_table_ref_and_range): Redo for slight
15906 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
15908 * keyboard.c, keyboard.h (num_input_events): Now size_t.
15909 This avoids undefined behavior on integer overflow, and is a bit
15910 more convenient anyway since it is compared to a size_t variable.
15912 Variadic C functions now count arguments with size_t, not int.
15913 This avoids an unnecessary limitation on 64-bit machines, which
15914 caused (substring ...) to crash on large vectors (Bug#8344).

15924 * fns.c (concat): Likewise.
15925 * frame.c (x_set_frame_parameters): Likewise.
15926 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
15927 0 if not found, not -1. All callers changed.
15929 * alloc.c (garbage_collect): Don't assume stack size fits in int.
15930 (stack_copy_size): Now size_t, not int.
15931 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
15933 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
15935 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
15936 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
15937 All callers changed.
15939 * lisp.h (multibyte_char_to_unibyte):
15940 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
15941 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

15952 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
15953 don't set the hook to nil, but remove the offending function instead.
15954 (Qcommand_hook_internal): Remove, unused.
15955 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
15956 Vcommand_hook_internal.

15959 (funcall_nil, funcall_not): New functions.
15960 (run_hook_with_args): Call each function through a `funcall' argument.

15974 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
15975 All callers changed.
15977 * w32.c (_wsa_errlist): Use braces for struct initializers.
15979 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

16045 * keyboard.c (readable_events):
16046 * process.c (wait_reading_process_output):
16047 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.

16095 Remove unused variable `width'.
16097 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
16099 * w32term.c (x_set_glyph_string_clipping):
16100 Don't pass uninitialized region to CombineRgn.

16124 2011-03-23 Julien Danjou <julien@danjou.info>
16126 * term.c (Fsuspend_tty, Fresume_tty):
16127 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16128 * window.c (temp_output_buffer_show):
16129 * insdel.c (signal_before_change):
16130 * frame.c (Fhandle_switch_frame):
16131 * fileio.c (Fdo_auto_save):

16134 * cmds.c (internal_self_insert):
16135 * callint.c (Fcall_interactively):
16136 * buffer.c (Fkill_all_local_variables):
16137 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16139 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16140 unconditionally since it does the check itself.
16142 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16144 Fix more problems found by GCC 4.5.2's static checks.
16146 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16147 the first time through the loop, since we know p0 < p1 then.
16148 This also avoids a gcc -Wstrict-overflow warning.
16150 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16151 leading to a memory leak, possible in functions like
16152 load_charset_map_from_file that can allocate an unbounded number
16153 of objects (Bug#8318).
16155 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16156 that could (at least in theory) be that large.
16158 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16159 This is less likely to overflow, and avoids undefined behavior if
16160 overflow does occur. All callers changed. Use strtoul to scan
16161 for the unsigned long integer.
16162 (pint2hrstr): Simplify and tune code slightly.
16163 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16165 * scroll.c (do_scrolling): Work around GCC bug 48228.
16166 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

16171 This also avoids a warning with gcc -Wstrict-overflow.
16173 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16176 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16178 * process.c (Fmake_network_process): Use socklen_t, not int,
16179 where POSIX says socklen_t is required in portable programs.
16180 This fixes a porting bug on hosts like 64-bit HP-UX, where
16181 socklen_t is wider than int (Bug#8277).
16182 (Fmake_network_process, server_accept_connection):
16183 (wait_reading_process_output, read_process_output):
16186 * process.c: Rename or move locals to avoid shadowing.

16196 Make tparam.h and terminfo.c consistent.
16197 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16198 Include tparam.h instead, since it declares them.
16199 * cm.h (PC): Remove extern decl; tparam.h now does this.
16200 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16201 * terminfo.c: Include tparam.h, to check interfaces.
16202 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16203 (tparam): Adjust signature to match interface in tparam.h;
16204 this removes some undefined behavior. Check that outstring and len
16205 are zero, which they always are with Emacs.
16206 * tparam.h (PC, BC, UP): New extern decls.
16208 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16209 (xftfont_open): Rename locals to avoid shadowing.
16211 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16212 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

16221 * xml.c (make_dom): Now static.
16223 * composite.c (composition_compute_stop_pos): Rename local to
16225 (composition_reseat_it): Remove unused locals.
16226 (find_automatic_composition, composition_adjust_point): Likewise.
16227 (composition_update_it): Mark var as initialized.
16228 (find_automatic_composition): Mark vars as initialized,
16229 with a FIXME (Bug#8290).

16232 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16233 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16234 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16235 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16236 to avoid shadowing.
16238 * textprop.c (property_change_between_p): Remove; unused.
16240 * intervals.c (interval_start_pos): Now static.
16242 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16245 Rename locals to avoid shadowing.
16247 * sound.c (wav_play, au_play, Fplay_sound_internal):
16248 Fix pointer signedness.
16249 (alsa_choose_format): Remove unused local var.
16250 (wav_play): Initialize a variable to 0, to prevent undefined
16251 behavior (Bug#8278).
16253 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16255 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16257 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16258 clobbering (Bug#8298).
16259 * sysdep.c (sys_subshell): Likewise.
16260 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16262 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16263 This should get cleaned up, so that child_setup has the
16264 same signature on all platforms.
16266 * callproc.c (call_process_cleanup): Now static.
16267 (relocate_fd): Rename locals to avoid shadowing.
16269 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16271 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16272 not to be necessary, and produces flickering.
16274 2011-03-20 Glenn Morris <rgm@gnu.org>
16276 * config.in: Remove file.
16278 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16280 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16281 are now in src/globals.h.
16282 (syms_of_minibuf): Remove spurious & from previous change.
16284 2011-03-20 Leo Liu <sdl.web@gmail.com>
16286 * minibuf.c (completing-read-function): New variable.
16287 (completing-read-default): Rename from completing-read.
16288 (completing-read): Call completing-read-function.
16290 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16292 * xfaces.c (Fx_load_color_file):
16293 Read color file from absolute filename (bug#8250).
16295 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16297 * makefile.w32-in: Update dependencies.
16299 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16301 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16308 (sigchld_handler): Now static.
16310 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16311 That way, the code declares only the vars that it needs.
16312 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16313 * s/cygwin.h (PTY_ITERATION): Likewise.
16314 * s/darwin.h (PTY_ITERATION): Likewise.

16321 (CONSTANTLIM): Remove; unused.
16322 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16323 Define only if needed.
16325 * unexelf.c (unexec): Name an expression,
16326 to avoid gcc -Wbad-function-cast warning.
16327 Use a different way to cause a compilation error if anyone uses
16328 n rather than nn, a way that does not involve shadowing.
16329 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16331 * deps.mk (unexalpha.o): Remove; unused.
16333 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16334 * unexec.h: New file.
16335 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16336 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16337 Depend on unexec.h.
16338 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16339 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16340 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16341 Change as necessary to match prototype in unexec.h.
16343 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

16360 (font_sort_entities): Mark var as initialized.
16362 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16364 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16396 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16397 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16398 some of which prompt warnings from gcc -Wbad-function-cast.
16399 (Fformat_time_string, Fencode_time, Finsert_char):
16400 (Ftranslate_region_internal, Fformat):
16401 Rename or remove local vars to avoid shadowing.
16402 (Ftranslate_region_internal): Mark var as initialized.
16404 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16407 * lisp.h (eassert): Check that the argument compiles, even if
16408 ENABLE_CHECKING is not defined.
16410 * data.c (Findirect_variable): Name an expression, to avoid
16411 gcc -Wbad-function-cast warning.

16423 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16424 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16426 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16427 (GC_STRING_CHARS): Remove; not used.
16428 (Fmemory_limit): Cast sbrk's returned value to char *.
16430 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16431 avoids undefined behavior in theory.

16436 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16437 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16438 to use the following functions instead of these macros.
16439 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16440 EMACS_INT, since callers assume the returned value fits in int.
16441 (upcase1): Likewise, for UPCASE_TABLE.
16442 (uppercasep, lowercasep, upcase): New static inline functions.
16443 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

16447 Rename locals to avoid shadowing.
16448 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16449 (regex_compile, re_search_2, re_match_2_internal):
16450 Remove unused local vars.
16451 (FREE_VAR): Rewrite so as not to use empty "else",
16452 which gcc can warn about.
16453 (regex_compile, re_match_2_internal): Mark locals as initialized.
16454 (RETALLOC_IF): Define only if needed.
16455 (WORDCHAR_P): Likewise. This one is never needed, but is used
16456 only in a comment talking about a compiler bug, so put inside
16457 the #if 0 of that comment.
16458 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16459 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16462 * search.c (boyer_moore): Rename locals to avoid shadowing.
16463 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16464 (PREV_CHAR_BOUNDARY): Likewise.
16466 * search.c (simple_search): Remove unused var.
16468 * dired.c (compile_pattern): Move decl from here ...

16476 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16477 Rename locals to avoid shadowing.
16478 (Fvertical_motion): Mark locals as initialized.
16480 * casefiddle.c (casify_object, casify_region): Now static.
16481 (casify_region): Mark local as initialized.
16483 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16485 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16486 New macros, so that the caller can use some names other than
16487 gcpro1, gcpro2, etc.
16488 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16490 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16491 argument, for consistency with GCPRO2_VAR, etc: it is now the
16492 prefix of the variable, not the variable itself. All uses
16494 * dired.c (directory_files_internal, file_name_completion):
16495 Rename locals to avoid shadowing.
16497 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16498 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16499 dired.c's scmp function, had undefined behavior.
16500 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16501 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16502 * buffer.h: ... to here, because these macros use current_buffer,
16503 and the new implementation with inline functions needs to have
16504 current_buffer in scope now, rather than later when the macros
16506 (downcase, upcase1): New static inline functions.
16507 (DOWNCASE, UPCASE1): Reimplement using these functions.
16508 This avoids undefined behavior in expressions like
16509 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16510 from race conditions in accessing the global variables
16511 case_temp1 and case_temp2.
16512 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16513 * lisp.h (case_temp1, case_temp2): Remove their decls.
16514 * character.h (ASCII_CHAR_P): Move from here ...
16515 * lisp.h: ... to here, so that the inline functions mentioned
16516 above can use them.
