1 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3 * xdisp.c (Qinhibit_debug_on_message): Now static.
5 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7 * nsterm.m (ns_update_begin): Set clip path to whole view by using
8 NSBezierPath (Bug#12131).
10 2012-09-10 Chong Yidong <cyd@gnu.org>
12 * fns.c (Fdelq, Fdelete): Doc fix.
14 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
16 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
17 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
19 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
21 * lisp.h (make_lisp_ptr): New macro to replace XSET.
22 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
25 2012-09-09 Eli Zaretskii <eliz@gnu.org>
27 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
28 left fringe if the window has a left margin. This avoids leaving
29 traces of the cursor because its leftmost pixel is not drawn over.
31 * dispnew.c (update_window_line): When the left margin area of a
32 screen line is updated, set the redraw_fringe_bitmaps_p flag of
33 that screen line. (Bug#12277)
35 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
37 Assume C89 or later for math functions (Bug#12381).
38 This simplifies the code, and makes it a bit smaller and faster,
39 and (most important) makes it easier to clean up signal handling
40 since we can stop worring about floating-point exceptions in
41 library code. That was a problem before C89, but the problem
42 went away many years ago on all practical Emacs targets.
43 * data.c, image.c, lread.c, print.c:
44 Don't include <math.h>; no longer needed.
45 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
46 might be autoconfigured, as that never happens.
48 * doprnt.c (DBL_MAX_10_EXP):
50 Remove. C89 or later always defines these.
51 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
52 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
53 (arith_error, domain_error, domain_error2):
54 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
55 no longer needed -- we simply return what C returns. All uses removed.
56 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
58 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
59 Remove. All uses expanded, as these macros are no longer used
60 more than once and are now more trouble than they're worth.
61 (Ftan): Use tan, not sin / cos.
62 (Flogb): Assume C89 frexp.
63 (fmod_float): Assume C89 fmod.
64 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
65 (init_floatfns): Remove. All uses removed.
67 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
69 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
70 compositeToPoint for OSX < 10.6 (Bug#12390).
72 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
74 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
75 This produces more-accurate results.
77 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
79 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
82 2012-09-08 Chong Yidong <cyd@gnu.org>
84 * syntax.c (Fstring_to_syntax): Doc fix.
86 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
88 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
89 in the internal border.
90 (x_set_window_size): Remove static variables and their usage.
91 (ns_redraw_scroll_bars): Fix NSTRACE arg.
92 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
93 fringe/internal border adjustment (Bug#11052).
94 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
95 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
96 (ns_fix_rect_ibw): Remove.
97 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
98 (ns_dumpglyphs_box_or_relief): Ditto.
99 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
101 (ns_dumpglyphs_image): Ditto.
102 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
104 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
105 their usage. Add fringe_extended_p and its use as in other terms.
106 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
107 scroll bar was removed.
108 (updateFrameSize): New function.
109 (windowDidResize): Move code to updateFrameSize and call it.
111 * nsterm.h (EmacsView): Add updateFrameSize.
113 2012-09-07 Chong Yidong <cyd@gnu.org>
115 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
117 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
119 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
121 More signal-handler cleanup (Bug#12327).
122 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
123 Problem introduced when merging patches. Noted by Eli Zaretskii in
124 <http://bugs.gnu.org/12327#67>.
125 * floatfns.c: Comment fix.
126 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
127 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
128 and anyway the declaration is harmless even if SIGDANGER is not defined.
129 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
130 defined BROKEN_FIONREAD). systty.h formerly did this, but other
131 source files not surprisingly expected syssignal.h to define, or
132 not define, SIGIO, and it's cleaner to do it that way, for consistency.
133 Include <sys/ioctl.h>, for FIONREAD.
134 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
135 This eliminates a problem whereby other files mysteriously had
136 to include "syssignal.h" before including "systty.h" if they
137 wanted to use "#ifdef SIGIO".
139 2012-09-07 Eli Zaretskii <eliz@gnu.org>
141 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
143 * w32.c (sigemptyset): Empty the set.
144 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
146 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
148 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
150 * alloc.c (mark_buffer): Revert unsafe marking optimization.
151 (mark_object): Likewise for frame objects.
153 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
155 * syssignal.h (handle_on_main_thread): Always declare,
156 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
157 This ports to platforms without HAVE_PTHREAD.
159 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
161 Signal-handler cleanup (Bug#12327).
162 Emacs's signal handlers were written in the old 4.2BSD style with
163 sigblock and sigmask and so forth, and this led to some
164 inefficiencies and confusion. Rewrite these to use
165 pthread_sigmask etc. without copying signal sets around. Also,
166 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
167 'signal', and instead use functions that do not attempt to take
168 over the system name space. This patch causes Emacs's text
169 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
170 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
171 Do not include <signal.h> or "syssignal.h", as these
172 modules do not use signals.
173 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
174 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
175 Do not include <signal.h>, as "syssignal.h" does that for us now.
176 * atimer.c (sigmask_atimers): New function.
177 (block_atimers, unblock_atimers): New functions,
178 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
180 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
181 no longer needed here.
182 * emacs.c (main): Inspect existing signal handler with sigaction,
183 so that there's no need to block and unblock SIGHUP.
184 * sysdep.c (struct save_signal): New member 'action', replacing
185 old member 'handler'.
186 (save_signal_handlers, restore_signal_handlers):
187 Use sigaction instead of 'signal' to save and restore.
188 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
189 New function. All users of 'signal' modified to use set_sighandler
190 if they're writeonly, and to use sys_signal if they're read+write.
191 (emacs_sigaction_init, forwarded_signal): New functions.
192 (sys_signal): Remove. All uses replaced by calls to sigaction
193 and emacs_sigaction_init, or by direct calls to 'signal'.
194 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
195 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
196 all uses replaced by pthread_sigmask etc. calls.
197 * syssignal.h: Include <signal.h>.
198 (emacs_sigaction_init, forwarded_signal): New decls.
199 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
200 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
201 (sigmask, sys_sigmask): Remove; no longer needed.
202 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
203 (sigblock, sigunblock, sigfree):
204 (sigsetmask) [!defined sigsetmask]:
205 Remove. All uses replaced by pthread_sigmask.
206 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
207 no longer need to be replaced, and its typical old uses
208 are now done via emacs_sigaction_init and sigaction.
209 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
210 (sys_sigdel): Remove; unused.
211 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
213 2012-09-06 Eli Zaretskii <eliz@gnu.org>
215 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
216 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
218 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
220 Explicitly mark buffer_defaults and buffer_local_symbols.
221 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
222 mark_local_symbols here.
223 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
224 since special buffers aren't marked here any more.
225 (allocate_buffer): Chain new buffer with all_buffers here...
226 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
228 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
229 (syms_of_buffer): Remove staticpro of the above.
230 (init_buffer_once): Set names for buffer_defaults and
231 buffer_local_symbols.
233 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
235 Use bool for booleans in font-related modules.
236 * font.c (font_intern_prop, font_style_to_value)
237 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
238 (generate_otf_features, font_check_otf_features, font_check_otf)
239 (font_match_p, font_list_entities, font_at):
240 * fontset.c (fontset_id_valid_p, reorder_font_vector
241 (fontset_find_font, Fset_fontset_font)
242 (face_suitable_for_char_p) [0]:
243 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
244 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
245 (m17n_flt_initialized, ftfont_shape_by_flt):
246 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
247 * nsfont.m (nsfont_draw):
248 * w32font.c (w32font_draw):
249 * w32term.c (x_draw_glyphless_glyph_string_foreground):
250 Use bool for booleans.
251 * font.h: Adjust to above API changes.
252 (struct font, struct font_driver, struct font_driver_list):
253 Use bool for booleans.
254 (struct font): Remove useless member encoding_type.
256 * fontset.c, xftfont.c: Omit unnecessary static decls.
258 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
260 * alloc.c (mark_object): Revert window marking code
261 since it's unsafe for the Fset_window_configuration.
263 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
265 Fix race conditions with signal handlers and errno (Bug#12327).
266 Be more systematic about preserving errno whenever a signal
267 handler returns, even if it's not in the main thread. Do this by
268 renaming signal handlers to distinguish between signal delivery
269 and signal handling. All uses changed.
270 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
271 * data.c (deliver_arith_signal): Rename from arith_error.
272 * dispnew.c (deliver_window_change_signal): Rename from
273 window_change_signal.
274 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
275 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
276 * keyboard.c (deliver_input_available_signal): Rename from
277 input_available_signal.
278 (deliver_user_signal): Rename from handle_user_signal.
279 (deliver_interrupt_signal): Rename from interrupt_signal.
280 * process.c (deliver_pipe_signal): Rename from send_process_trap.
281 (deliver_child_signal): Rename from sigchld_handler.
282 * atimer.c (handle_alarm_signal):
283 * data.c (handle_arith_signal):
284 * dispnew.c (handle_window_change_signal):
285 * emacs.c (handle_fatal_signal, handle_danger_signal):
286 * keyboard.c (handle_input_available_signal):
287 * keyboard.c (handle_user_signal, handle_interrupt_signal):
288 * process.c (handle_pipe_signal, handle_child_signal):
289 New functions, with the actual signal-handling code taken from the
290 original respective signal handlers, sans the sporadic attempts to
291 preserve errno, since that's now done by handle_on_main_thread.
292 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
293 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
294 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
296 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
297 Move initialization of main_thread to sysdep.c's init_signals.
298 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
299 our usage, and simplifies the mainline code.
300 (record_child_status_change): New static function, as a helper
301 for handle_child_signal, and with most of the old child handler's
303 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
304 (handle_child_signal): Use the above.
305 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
306 Moved here from emacs.c.
307 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
308 code moved here from emacs.c's main function.
309 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
310 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
311 lets callers save and restore errno properly.
313 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
315 Remove redundant or unused things here and there.
316 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
317 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
318 * editfns.c (Fcompare_buffer_substrings): Likewise.
319 * frame.h (struct terminal, struct font_driver_list):
320 Remove redundant declarations.
321 * window.h (Qleft, Qright): Likewise.
323 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
325 Do not mark objects from deleted buffers, windows and frames.
326 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
327 (mark_object): Likewise for windows and frames.
329 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
331 * alloc.c (valid_lisp_object_p): Treat killed buffers,
332 buffer_defaults and buffer_local_symbols as valid objects.
333 Return special value to denote them.
335 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
337 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
338 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
339 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
340 (file_name_absolute_p, Fsubstitute_in_file_name):
341 (check_executable, check_writable, Ffile_accessible_directory_p)
342 (Fset_file_selinux_context, Fdefault_file_modes)
343 (Finsert_file_contents, choose_write_coding_system)
344 (Fwrite_region, build_annotations, a_write, e_write)
346 * filelock.c (boot_time_initialized, get_boot_time)
347 (get_boot_time_1, lock_file_1, within_one_second):
348 * floatfns.c (in_float):
349 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
350 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
351 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
352 * lisp.h (struct Lisp_Hash_Table.cmpfn):
353 * window.c (compare_window_configurations):
354 Use bool for booleans.
355 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
356 (Fdefault_file_modes): Now mode_t, not int, for modes.
357 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
358 (internal_delete_file): Now returns void, not a (boolean) int,
359 since nobody was looking at the return value.
360 * lisp.h, window.h: Adjust to above API changes.
362 * xdisp.c (set_message): Simplify and reindent last change.
364 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
366 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
368 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
370 * eval.c (call_debugger): Make the function non-static so that we
371 can call it from set_message.
373 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
374 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
376 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
378 Give more-useful info on a fatal error (Bug#12328).
379 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
380 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
381 of doing the work ourselves.
382 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
384 (fatal_error_backtrace): New function, taken from the guts
385 of the old fatal_error_signal, but with a new option to output
387 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
388 info about the signal than just its number.
389 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
390 * sysdep.c: Include <execinfo.h>
391 (emacs_backtrace): New function, taken partly from the previous
392 code of the 'die' function.
393 (emacs_abort): Call fatal_error_backtrace rather than abort.
395 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
397 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
398 eager (load-time) macro-expansion.
399 * lisp.mk (lisp): Add macroexp.
401 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
403 Simplify redefinition of 'abort' (Bug#12316).
404 Do not try to redefine the 'abort' function. Instead, redo
405 the code so that it calls 'emacs_abort' rather than 'abort'.
406 This removes the need for the NO_ABORT configure-time macro
407 and makes it easier to change the abort code to do a backtrace.
408 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
409 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
410 Remove; sysdep.c's emacs_abort now takes its place.
411 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
412 'abort' changed to use 'emacs_abort'.
413 * msdos.c (dos_abort) [defined abort]: Remove; not used.
414 (abort) [!defined abort]: Rename to ...
415 (emacs_abort): ... new name.
416 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
417 the place of the old 'abort' in emacs.c.
418 * w32.c, w32fns.c (abort): Do not #undef.
419 * w32.c (emacs_abort): Rename from w32_abort.
421 2012-09-04 Eli Zaretskii <eliz@gnu.org>
423 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
424 offsets[j].dv, since the y axis of the screen coordinates points
425 down, while the y axis of the font definition coordinates points
426 up. This fixes display of Arabic diacritics such as KASRA and
427 KASRATAN. (Bug#11860)
429 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
431 Be more systematic about _setjmp vs setjmp.
432 * alloc.c (test_setjmp, mark_stack):
433 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
434 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
435 (png_load, my_error_exit, jpeg_load):
436 * process.c (send_process_trap, send_process):
437 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
438 The underscored versions are up to 30x faster on some hosts.
439 Formerly, the code used setjmp+longjmp sometimes and
440 _setjmp+_longjmp at other times, with no particular reason to
441 prefer setjmp+longjmp.
443 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
445 Fix minor problem found by static checking.
446 * buffer.c (Fdelete_all_overlays): Return nil.
448 2012-09-03 Martin Rudalics <rudalics@gmx.at>
450 * buffer.c (Fdelete_all_overlays): New function.
452 2012-09-03 Chong Yidong <cyd@gnu.org>
454 * gtkutil.c: Add extern decl for Qxft.
456 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
458 * emacs.c, eval.c: Use bool for boolean.
459 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

461 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
462 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
463 (main, decode_env_path, Fdaemon_initialized):
464 * eval.c (call_debugger, Finteractive_p, interactive_p):
465 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
466 (maybe_call_debugger, Fbacktrace):

472 EXCLUDE_SUBRS_P. All callers changed.
473 * dispextern.h, lisp.h: Reflect above API changes.
474 * firstfile.c (dummy): Use the address of 'main', whose signature
475 won't change, instead of the address of 'initialize', whose
476 signature just changed from int to bool.
477 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
478 * msdos.c (fatal_error_in_progress): ... from here.
479 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead

482 REDISPLAYING_P when unwinding, instead of saving its previous,
483 always-false value and then restoring it.
485 Clean up some extern decls.
486 Mostly, this hoists extern decls out of .c files and into .h files.
487 That way, we're more likely to catch errors if the interfaces change.

510 Remove now-redundant extern decls.
511 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
512 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
514 * xfaces.c: Remove unnecessary static decls.
515 * xterm.c (updating_frame): Remove decl of nonexistent object.
517 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
518 when building globals.h, as the objects that are not built on
519 this host are not needed to compile C files on this host.
521 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
523 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

535 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
536 (format_time_string, general_insert_function)
537 (make_buffer_string, make_buffer_string_both)
538 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

550 (set_intervals_multibyte_1, set_intervals_multibyte):
551 * keyboard.c (decode_timer):
552 Use bool for boolean.

573 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
574 more than one grapheme cluster passed to the shaper: compute the
575 offset adjustment values separately for each cluster. (Bug#11860)
577 * image.c: Restore mistakenly removed inclusion of w32.h. Without
578 it, GCC doesn't see prototypes of w32_delayed_load, and complains
579 about implicit conversions from integer to pointer.
581 2012-09-01 Daniel Colascione <dancol@dancol.org>
583 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
584 system used too early.

637 window system declarations.
639 * frame.h: Move common functions here: set_frame_menubar,
640 x_set_window_size, x_sync, x_get_focus_frame,
641 x_set_mouse_position, x_set_mouse_pixel_position,
642 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
643 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
644 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,
645 x_activate_menubar, x_real_positions, x_bitmap_icon,

728 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
729 Add window_closed and button_values. Add void as return value for
730 add(Button|String|Split). addButton takes int instead of Lisp_Object.

923 (load_charset_map_from_file, map_charset_chars)
924 (Fdefine_charset_internal, define_charset_internal)
925 (Fdeclare_equiv_charset, find_charsets_in_text)
926 (Ffind_charset_region, char_charset, Fiso_charset):

928 (sub_char_table_set, sub_char_table_set_range)
929 (char_table_set_range, optimize_sub_char_table)
930 (map_sub_char_table):
931 Use bool for boolean.
932 * character.c (str_to_unibyte): Omit last boolean argument; it was
933 always 0. All callers changed.
934 * character.h, charset.h: Adjust to match previous changes.
935 * character.h (char_printable_p): Remove decl of nonexistent function.
936 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
937 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
938 are all boolean, so make them single-bit bitfields.
940 * lisp.h (ASET): Remove attempt to detect side effects.
941 It was meant to be temporary and it often doesn't work,
942 because when IDX has side effects the behavior of IDX==IDX
943 is undefined. See Stefan Monnier in
944 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
946 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
948 * lisp.h (functionp): New function (extracted from Ffunctionp).
950 * eval.c (Ffunctionp): Use it.
952 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
954 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
955 as that's faster and simpler than static storage. Don't bother
956 with the g_main_context_query overhead if g_main_context_pending
957 says no events are pending.
958 (gfds, gfds_size): Remove these static vars.
959 (xgselect_initialize): Remove; no longer needed.
960 All uses and decls removed.
962 * emacs.c (fatal_error_signal_hook): Remove.
963 All uses removed. This leftover from old code was always 0.
965 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
966 * casefiddle.c (casify_object, casify_region):
967 * casetab.c (set_case_table):
968 * category.c, category.h (word_boundary_p):
969 * category.h (CHAR_HAS_CATEGORY):
970 Use bool for booleans, instead of int.
972 2012-08-25 Eli Zaretskii <eliz@gnu.org>
974 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
976 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
978 On assertion failure, print backtrace if available.
979 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
980 (die) [ENABLE_CHECKING]: Print a backtrace if available.
981 * Makefile.in (LIB_EXECINFO): New macro.
984 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
985 * bytecode.c (exec_byte_code):
986 * callint.c (check_mark, Fcall_interactively):
987 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
988 (getenv_internal, sync_process_alive, call_process_exited):
989 * lisp.h (USE_SAFE_ALLOCA):
990 Use bool for booleans, instead of int.
991 * lisp.h, process.h: Adjust prototypes to match above changes.
992 * callint.c (Fcall_interactively): Don't assume the mark's
993 offset fits in 'int'.
995 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
997 * buffer.c, buffer.h: Use bool for boolean.
998 * buffer.c (reset_buffer_local_variables)
999 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1000 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1001 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1002 (overlay_touches_p, overlay_strings, Foverlay_put)
1003 (report_overlay_modification, call_overlay_mod_hooks):
1004 (mmap_enlarge, mmap_set_vars):
1005 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1006 Use bool for booleans, instead of int.
1007 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1008 since the 1-or-0 return value is always ignored anyway.
1009 (mmap_initialized_p):
1010 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1011 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1013 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1015 * bidi.c: Use bool for boolean.
1016 This is a bit more readable, and makes the text segment of bidi.o
1017 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1018 Presumably it's faster too.
1019 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1021 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1022 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1023 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1024 (bidi_explicit_dir_char, bidi_level_of_next_char)
1025 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1026 Use bool for booleans, instead of int.
1027 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1028 (bidi_unshelve_cache): Adjust decls to match code.
1030 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1032 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1035 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1037 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1038 * atimer.h: Include <stdbool.h>.
1040 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1042 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1043 compile time tests instead of run time tests on systems that do
1045 (FRAME_MAC_P): Remove leftover from deleted code.
1046 * frame.c (syms_of_frame): Remove leftover from deleted code.
1048 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1050 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1052 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1054 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1055 Otherwise, the compiler complains about (A?B:C) where B is void
1056 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1057 (fontset_add): Return void, for FONTSET_ADD.
1059 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1061 * alloc.c: Use bool for booleans.
1062 (gc_in_progress, abort_on_gc)
1063 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1064 (dont_register_blocks) [GC_MALLOC_CHECK]:
1065 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1066 (check_string_bytes, make_specified_string, memory_full)
1067 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1068 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1069 (mark_stack, valid_pointer_p, make_pure_string)
1070 (Fgarbage_collect, survives_gc_p, gc_sweep):
1071 Use bool for booleans, instead of int.
1072 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1073 Remove unused local.
1074 * alloc.c (PURE_POINTER_P):
1075 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1076 * editfns.c (Fformat):
1077 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1079 * fns.c (sweep_weak_table):
1080 * lisp.h (suppress_checking, push_message, survives_gc_p)
1081 (make_pure_string, gc_in_progress, abort_on_gc):
1082 * lread.c (readchar, read1):
1083 * print.c (Fprin1_to_string):
1084 * xdisp.c (push_message):
1085 Use bool for booleans affected directly or indirectly by
1088 Make recently-introduced setters macros.
1089 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1090 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1091 (set_fontset_default, set_fontset_fallback): Rename from their
1092 upper-case counterparts, and make them functions rather than macros.
1093 This is more consistent with the other recently-introduced setters.
1094 These don't need to be inline, since they're local.
1096 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1098 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1099 the loop (Bug#12247).
1101 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1103 * lisp.h (vcopy): Use memcpy rather than our own loop.
1104 This fixes a performance regression introduced by the recent
1105 addition of vcopy. This means 'vcopy' will need to be modified
1106 for a copying collector, but that's OK. Also, tighten the
1107 checking in the assertion.
1109 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1111 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1112 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1113 non-base glyph for the width of the base character, according to
1114 what x_draw_composite_glyph_string_foreground expects.
1115 Generate WADJUST value according to composition_gstring_width's
1116 expectations, to produce correct width of the composed character.
1117 Reverse the sign of the DU offset produced by ScriptPlace.
1119 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1121 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1123 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1125 Avoid direct writes to contents member of struct Lisp_Vector.
1126 * lisp.h (vcopy): New function to copy data into vector.
1127 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1128 * fns.c (Ffillarray): Use ASET.
1129 * keyboard.c (timer_check_2): Use AREF and ASET.
1130 (append_tool_bar_item, Frecent_keys): Use vcopy.
1131 * lread.c (read_vector): Use ASET.
1132 * msdos.c (Frecent_doskeys): Use vcopy.
1133 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1134 (Finternal_merge_in_global_face): Use ASET and vcopy.
1135 * xfont.c (xfont_list_pattern): Likewise.
1137 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1139 * window.c (Fwindow_point): For the selected window always return
1140 the position of its buffer's point.
1141 (Fset_window_point): For the selected window always go in its
1142 buffer to the specified position.
1144 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1146 Setter macros for fontsets.
1147 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1148 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1149 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1152 2012-08-20 Glenn Morris <rgm@gnu.org>
1154 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1155 Don't assume that `ln -f' works.
1157 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1159 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1160 and later about non-assignments with no effect. See discussion at
1161 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1164 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1166 Inline setter functions for Lisp_Objects slots of struct specbinding.
1167 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1170 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1172 * window.c (select_window): Always make selected window's buffer
1175 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1177 Use AREF and ASET for docstrings of category tables.
1178 * category.h (CATEGORY_DOCSTRING): Use AREF.
1179 (SET_CATEGORY_DOCSTRING): Use ASET.
1180 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1182 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1184 Inline setter functions for hash table members.
1185 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1186 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1187 (set_hash_key_and_value, set_hash_index, set_hash_next)
1188 (set_hash_hash): New functions.
1189 * charset.c, fns.c: Adjust users.
1191 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1193 Inline getter and setter functions for per-buffer values.
1194 * buffer.h (per_buffer_default, set_per_buffer_default)
1195 (per_buffer_value, set_per_buffer_value): New functions.
1196 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1197 * buffer.c, data.c: Adjust users.
1199 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1201 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1203 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1205 Rely on <config.h> + <unistd.h> to declare 'environ',
1206 as gnulib does this if the system doesn't.
1207 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1208 Remove declaration. MS-Windows declares it on stdlib.h which is
1209 included by conf_post.h.
1210 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1211 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1212 * vm-limit.c: Include <unistd.h>, for 'environ'.
1214 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1215 (start_of_data): Remove decl; mem-limits.h provides it.
1217 * xdisp.c (handle_invisible_prop): Make it a bit faster
1218 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1220 2012-08-19 Chong Yidong <cyd@gnu.org>
1222 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1225 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1227 * .gdbinit: Use call instead of set when calling a function in the
1230 * data.c (set_internal): Don't use set_blv_found.
1231 (Fkill_local_variable): Likewise.
1233 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1235 * nsfont.m (ns_ascii_average_width): Ensure the string
1236 ascii_printable is initialized with a null-terminated character
1237 array. Otherwise, it can contain undesired extra characters.
1239 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1241 port new setting code to Sun C 5.8 2005/10/13
1242 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1243 Return void, not Lisp_Object. Otherwise, the compiler
1244 complains about (A?B:C) where B is void and C is Lisp_Object
1245 when compiling CHAR_TABLE_SET, due to the recent change to
1246 the API of sub_char_table_set_contents.
1248 2012-08-18 Chong Yidong <cyd@gnu.org>
1250 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1251 for the string case (Bug#3874).
1253 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1255 * buffer.h (BSET): Remove (Bug#12215).

1325 New setter functions.
1327 * termhooks.h (TSET): Remove (Bug#12215).

1329 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1330 (TERMHOOKS_INLINE): New macro.
1331 (tset_charset_list, tset_selection_alist): New setter functions.
1332 * terminal.c (TERMHOOKS_INLINE):
1333 Define to EXTERN_INLINE, so that the corresponding functions
1334 are compiled into code.
1335 (tset_param_alist): New setter function.
1337 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
1339 * keyboard.h (KSET): Remove (Bug#12215).

2083 value of EMACSLOADPATH, as it is no longer needed.
2084 (check_windows_init_file): Now external, not static.

2135 * alloc.c (record_xmalloc): New function.
2136 * lisp.h (record_xmalloc): New decl.
2137 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts

2139 needed. All uses changed.
2140 * print.c (print_string, print_error_message): Avoid length recalc.
2142 Improve fix for macroexp crash with debugging (Bug#12118).
2143 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

2177 with addition of handling of symlinks and support for 'lstat'.
2178 If possible, get file's attributes and security information by
2179 handle, not by name. Produce S_IFLNK bit for symlinks, when
2180 called from 'lstat'.
2181 (stat, lstat): New functions, call 'stat_worker'.
2182 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2183 symlinks when the underlying filesystem supports them.

2188 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2189 checking subscripts; problem introduced with the recent
2190 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2191 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2192 since it's used in non-static inline functions now.
2194 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

2692 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
2693 Zaretskii in <http://bugs.gnu.org/12036#13>.
2694 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
2695 needed now that we have gdb_make_enums_visible.
2696 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
2697 (enum enum_USE_LSB_TAG):
2698 New enum types, packaging up enums that need to be exported to GDB.

2719 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2721 Fast save_excursion_save and save_excursion_restore.
2722 * lisp.h (struct Lisp_Excursion): New data type.
2723 (PVEC_EXCURSION): New pseudovector type.
2724 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
2725 to deal with it. Adjust comments.

2740 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
2741 emacs.c, as this is a more-suitable home. Had this been done earlier
2742 the fix for 12036 would have avoided some of the problems noted in
2743 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
2744 would have been more obvious.
2745 * emacs.c: Do not include <verify.h>; no longer needed.
2746 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
2747 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
2748 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2749 Remove; now done in lisp.h.

2754 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
2755 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
2756 not be usable in #if. This simplifies things.
2758 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
2760 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

2765 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
2766 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
2767 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
2768 Adjust to changes in lisp.h and emacs.c, by using
2769 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
2770 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
2771 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
2772 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
2773 instead of gdb_valbits.
2774 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
2775 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
2776 instead of gdb_array_mark_flag.
2777 (xboolvector): Get size from $->size, not $->header.size.
2778 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
2779 (xreload, hook-run, hookpost-run): Remove.
2780 * emacs.c: Include <verify.h>.
2781 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
2782 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
2784 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
2785 (gdb_USE_LSB_TAG): New enum constants.
2786 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2787 Also define these as enum constants, so they're visible to GDB.
2788 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
2789 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
2790 as constants, so they're visible to GDB.

2793 Now enum constants, not macros, so they're visible to GDB.
2794 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
2795 more convenient now. All uses changed.
2796 (VALMASK) [USE_LSB_TAG]: Also define in this case.

2807 add argument, tune behavior, and adjust all callers.
2809 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
2811 Use typedef for EMACS_INT, EMACS_UINT.
2812 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
2813 than macros. This simplifies debugging in the usual case, since
2814 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
2815 and it allows expressions involving EMACS_INT casts.
2816 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
2818 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

2830 Adjust buffer text indirection counters at the end of Fkill_buffer.
2831 * buffer.c (Fkill_buffer): Adjust indirection counters when the
2832 buffer is definitely dead. This should really fix an issue reported
2833 by Christoph Scholtes again. (Bug#12007).
2834 (init_buffer_once): Initialize indirection counters of
2835 buffer_defaults and buffer_local_symbols (for sanity and safety).
2837 2012-07-24 Eli Zaretskii <eliz@gnu.org>
2839 * xdisp.c (init_iterator): Don't compute dimensions of truncation
2840 and continuation glyphs on tooltip frames, leave them at zero.

2868 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
2870 Swap buffer text indirection counters in Fbuffer_swap_text.
2871 * buffer.c (Fbuffer_swap_text): Swap indirections too.
2872 This avoids crash reported by Christoph Scholtes at
2873 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
2875 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
2877 * nsmenu.m (Popdown_data): New struct.

2900 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
2902 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
2903 as it's limited by the amount of memory, not by INT_MAX.
2905 2012-07-21 Eli Zaretskii <eliz@gnu.org>
2907 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
2908 in special-event-map. See the discussion at

2989 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
2990 'for_each_per_buffer_object_at'.
2991 All uses changed. It's better to use upper-case for macros that

3043 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3045 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3046 when invoking (make-bool-vector N t) and N is a positive

3054 padding before the data member of a bool vector.
3055 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3056 than doing the check by hand with an abort ().
3058 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3060 * eval.c (Fdefvar): Don't check constants since we only set the var if
3061 it's not yet defined anyway (bug#11904).
3063 * lisp.h (last_undo_boundary): Declare new var.
3064 * keyboard.c (command_loop_1): Set it.
3065 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3066 were auto-added by the command loop (bug#11774).
3068 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3070 * w32font.c (Qsymbol): Remove local definition.

3579 function attribute, so we only use it if it exists in the
3582 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
3584 Avoid call to strlen in fast_c_string_match_ignore_case.
3585 * search.c (fast_c_string_match_ignore_case): Change to use
3586 length argument. Adjust users accordingly.
3587 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
3589 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

3628 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
3630 Remove "#define unix" that is no longer needed (Bug#11905).
3631 * s/aix4-2.h (unix): Remove; no longer needed.
3633 EMACS_TIME simplification (Bug#11875).
3634 This replaces macros (which typically do not work in GDB)
3635 with functions, typedefs and enums, making the code easier to debug.
3636 The functional style also makes code easier to read and maintain.
3637 * systime.h: Include <sys/time.h> on all hosts, not just if
3638 WINDOWSNT, since 'struct timeval' is needed in general.
3639 (EMACS_TIME): Now a typedef, not a macro.
3640 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
3642 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

3645 (EMACS_TIME_LE): Now functions, not macros.
3646 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
3647 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
3648 which are not functions. All uses rewritten to use:
3649 (make_emacs_time): New function.
3650 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
3651 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
3652 not functions. All uses rewritten to use the following, respectively:
3653 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
3654 (add_emacs_time, sub_emacs_time): New functions.
3655 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
3656 * fileio.c (Fcopy_file):
3657 * xterm.c (XTflash): Get the current time closer to when it's used.
3658 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

3665 * frame.c (Fmake_terminal_frame):
3666 * gtkutil.c (get_utf8_string):
3668 * nsmenu.m (ns_update_menubar):
3669 * regex.c (regerror):
3670 Prefer memcpy to strncpy and strncat when either will do.
3671 * fileio.c (Fsubstitute_in_file_name):
3672 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
3673 (menu_separator_name_p):
3674 * nsmenu.m (ns_update_menubar):
3675 Prefer memcmp to strncmp when either will do.
3676 * nsterm.m: Include <ftoastr.h>.
3678 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
3679 Prefer snprintf to strncpy.
3680 * nsterm.m (ns_term_init):
3681 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
3682 * nsterm.m (ns_term_init):
3683 Avoid the need for strncpy, by using build_string or
3684 make_unibyte_string directly. Use dtoastr, not snprintf.
3685 * process.c (Fmake_network_process): Diagnose service names that
3686 are too long, rather than silently truncating them or creating
3687 non-null-terminated names.
3688 (Fnetwork_interface_info): Likewise, for interface names.
3689 * sysdep.c (system_process_attributes) [GNU_LINUX]:
3690 Prefer sprintf to strncat.
3691 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
3692 Prefer vsnprintf to vsprintf + strncpy.
3694 2012-07-10 Glenn Morris <rgm@gnu.org>
3696 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
3697 Clarify fallback case.
3699 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3701 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
3702 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
3703 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
3704 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
3705 where argument type is known to be a Lisp_Cons.
3707 2012-07-10 Tom Tromey <tromey@redhat.com>
3709 * bytecode.c (BYTE_CODE_THREADED): New macro.
3710 (BYTE_CODES): New macro. Replaces all old byte-code defines.

3717 Optimize pure C strings initialization.
3718 * lisp.h (make_pure_string): Fix prototype.
3719 (build_pure_c_string): New function, defined as static inline. This
3720 provides a better opportunity to optimize away calls to strlen when
3721 the function is called with compile-time constant argument.
3722 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
3723 argument, adjust users accordingly. Use build_pure_c_string where
3725 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
3726 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
3727 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
3729 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3731 Avoid calls to strlen in miscellaneous functions.
3732 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
3733 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
3734 * lread.c (openp): Likewise.
3736 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3738 Avoid calls to strlen in path processing functions.
3739 * fileio.c (file_name_as_directory): Add comment. Change to add
3740 srclen argument and return the length of result. Adjust users
3742 (directory_file_name): Fix comment. Change to add srclen argument,

3744 Adjust users accordingly.
3745 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
3747 2012-07-10 Glenn Morris <rgm@gnu.org>
3749 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

3754 * s/gnu.h (DATA_START): Move definitions to configure.
3756 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
3757 We include usg5-4-common.h, which defines them both.
3759 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
3760 O_RDONLY already includes it).
3762 Stop ns builds setting the EMACSLOADPATH environment variable.
3763 * nsterm.m (ns_load_path): Rename from ns_init_paths.
3764 Now it does not set EMACSLOADPATH, just returns the load-path string.
3765 * nsterm.h: Update accordingly.
3766 * lread.c [HAVE_NS]: Include nsterm.h.
3767 (init_lread) [HAVE_NS]: Use ns_load_path.
3768 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
3770 2012-07-09 Glenn Morris <rgm@gnu.org>
3772 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
3773 since the included bsd-common.h does so.
3775 Stop ns builds setting the EMACSPATH environment variable.
3776 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
3777 (ns_init_paths): Do not set EMACSPATH.
3778 * nsterm.h (ns_exec_path): Add it.
3779 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
3782 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
3784 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
3786 * process.c (wait_reading_process_output): 'waitchannels' was unset
3787 when read_kbd || !NILP (wait_for_cell); fix this.
3789 Add GCC-style 'const' attribute to functions that can use it.
3790 * character.h (char_resolve_modifier_mask):
3791 * keyboard.h (make_ctrl_char):
3792 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
3793 (init_character_once, next_almost_prime, init_fns, init_image)
3794 (flush_pending_output, init_sound):

3799 Declare the dummy function with ATTRIBUTE_CONST.
3800 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
3801 Add decls with ATTRIBUTE_CONST.
3803 Minor improvements to make_formatted_string.
3804 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
3805 where int is good enough, as vsprintf returns an int.
3806 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
3808 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3810 Use make_formatted_string to avoid double length calculation.
3811 * lisp.h (make_formatted_string): New prototype.
3812 * alloc.c (make_formatted_string): New function.
3813 * buffer.c (Fgenerate_new_buffer_name): Use it.

3817 * frame.c (make_terminal_frame, set_term_frame_name)
3818 (x_report_frame_params): Likewise.
3819 * image.c (gs_load): Likewise.
3820 * minibuf.c (get_minibuffer): Likewise.

3835 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3837 Move marker debugging code under MARKER_DEBUG.
3838 * marker.c (MARKER_DEBUG): Move marker debugging code under
3839 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
3840 for bootstrap with --enable-checking (~3x slowdown reported
3841 by Juanma Barranquero <lekktu@gmail.com>).
3842 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
3844 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
3846 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
3847 See <http://bugs.gnu.org/11825#29>.
3849 2012-07-08 Eli Zaretskii <eliz@gnu.org>
3851 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
3852 has no font, use the frame's font. (Bug#11813)
3853 (display_line): Add commentary about displaying truncation glyphs
3855 (produce_special_glyphs): Move here from term.c.
3857 * term.c (produce_special_glyphs): Move to xdisp.c.
3859 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
3862 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
3864 * xdisp.c (display_line): Avoid warning about implicit declaration
3867 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
3869 * lisp.h: Remove empty conditional.
3871 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3873 * lread.c (load_path_check): Now static.
3875 Fix some minor --with-ns problems found by static checking.
3876 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
3877 (x_set_font) [!HAVE_X_WINDOWS]:
3878 * image.c (xpm_load_image) [HAVE_NS]:
3879 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
3880 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
3881 Remove unused local.
3882 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
3883 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.

3885 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
3886 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
3887 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
3888 Fix pointer signedness problem.
3889 * xfaces.c (FRAME_X_FONT_TABLE):
3890 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
3892 2012-07-07 Glenn Morris <rgm@gnu.org>
3894 * lread.c (load_path_check): New function, split from init_lread.
3895 (init_lread): Reorganize. Motivation:
3896 If EMACSLOADPATH is set, check/warn about that rather than the
3897 defaults, which we are not going to use. Hence we can remove
3898 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
3899 Don't warn if site-lisp directories are missing.
3900 If not installed, start from a blank load-path, since
3901 PATH_LOADSEARCH refers to the eventual installation directories.
3903 2012-07-07 Eli Zaretskii <eliz@gnu.org>
3905 Support truncation and continuation glyphs on GUI frames, when
3906 fringes are disabled. (Bug#11832)
3907 * xdisp.c (init_iterator): Get dimensions of truncation and
3908 continuation glyphs even if on GUI frames.
3909 Adjust it->last_visible_x on GUI frames when the left or right fringes,
3910 or both, are absent.
3911 (start_display, move_it_in_display_line_to): Handle the case of a
3912 GUI frame without a fringe to display continuation or truncation
3914 (insert_left_trunc_glyphs): Support GUI frames: make sure
3915 truncation glyphs overwrite enough glyphs from the current line to
3916 have sufficient space in pixels.
3917 (display_line): Support truncation and continuation glyphs on GUI
3918 frames. If some spare pixels are left on the line after inserting
3919 the truncation glyphs, fill that space with a stretch glyph of a
3920 suitably computed width.
3922 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
3923 produce_glyphs, to support GUI sessions.
3925 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3927 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
3929 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
3931 Do not require float-time's arg to fit in time_t (Bug#11825).
3932 This works better on hosts where time_t is unsigned, and where
3933 float-time is applied to the (negative) difference between two times.
3934 * editfns.c (decode_time_components): Last arg is now double *,
3935 not int *, and means to store all the result as a double, without
3936 worrying about whether the seconds part fits in time_t.
3937 All callers changed.
3938 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
3939 All callers changed.
3940 (Ffloat_time): Do not fail merely because the specified time falls
3941 outside of time_t range.
3943 2012-07-07 Glenn Morris <rgm@gnu.org>
3945 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

3949 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
3951 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
3952 Update dependencies.
3954 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
3956 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3958 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
3959 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
3960 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3961 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
3962 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
3963 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
3965 * xfont.c (compare_font_names): Redo to omit the need for casts.
3967 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
3969 * xfns.c (Fx_change_window_property): Doc fix.
3970 * w32fns.c (Fx_change_window_property): Doc fix.
3972 * w32fns.c (Fx_window_property): Accept the same arguments as the
3973 X Windows version. Doc fix.
3974 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3976 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3977 Eli Zaretskii <eliz@gnu.org>
3979 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
3980 Windows-specific code from nt/config.nt moved here.
3981 Obsolete settings removed.
3983 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3985 * process.c: Avoid unnecessary calls to gettime.
3986 (wait_reading_process_output): Don't get the time of day
3987 when gobbling data immediately and not waiting, as there's no need
3988 for it in that case. This removes a FIXME.
3990 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
3992 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
3993 is defined (Bug#11768).
3995 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3997 Fix marker debugging code.
3998 * marker.c (byte_char_debug_check): Do not perform the check
3999 if buffer is not multibyte.
4000 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4001 Call byte_char_debug_check with correct arguments.
4003 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4005 Compile marker debugging code only if ENABLE_CHECKING is defined.
4006 * marker.c (byte_char_debug_check, count_markers):
4007 Use only if ENABLE_CHECKING is defined.
4008 (byte_debug_flag): Remove.
4009 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4010 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4012 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4014 Avoid code repetition in marker-related functions.
4015 * marker.c (attach_marker): New function.
4016 (Fset_marker, set_marker_restricted, set_marker_both)
4017 (set_marker_restricted_both): Use it.
4018 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4019 Consistently rename charno to charpos.
4020 (marker_position): Add eassert.
4021 (marker_byte_position): Convert to eassert.

4027 * marker.c (unchain_marker): Simplify. Fix comments.
4029 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4031 Introduce fast path for the widely used marker operation.
4032 * alloc.c (build_marker): New function.
4033 * lisp.h (build_marker): New prototype.
4034 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4035 * composite.c (autocmp_chars): Likewise.
4036 * editfns.c (buildmark): Remove.
4037 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4038 (save_restriction_save): Use build_marker.
4039 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4040 * window.c (save_window_save): Likewise.
4042 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4044 Do not use Fdelete_overlay in delete_all_overlays
4045 to avoid redundant calls to unchain_overlay.
4046 * buffer.c (drop_overlay): New function.
4047 (delete_all_overlays, Fdelete_overlay): Use it.
4048 * minibuf.c (get_minibuffer): Fix comment.
4050 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4052 Port to OpenBSD 5.1 amd64.
4053 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4054 This is needed for OpenBSD, and should be harmless on all BSD systems.
4055 Also, include <sys/sysctl.h>, as it should be available on all
4056 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4057 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4058 use p_pid member, not kp_proc.pid.
4060 2012-07-06 Glenn Morris <rgm@gnu.org>
4062 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4064 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4066 More xmalloc and related cleanup.
4067 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
4068 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
4069 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

4072 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
4073 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
4074 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4075 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4077 Omit needless casts involving void * pointers and allocation.
4078 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4079 as the former is more robust if P's type is changed.
4080 Prefer xzalloc to xmalloc + memset 0.
4081 Simplify malloc-or-realloc to realloc.
4082 Don't worry about xmalloc returning a null pointer.
4083 Prefer xstrdup to xmalloc + strcpy.
4084 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4086 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4087 alloca of a constant.
4089 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4091 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4092 hscroll is larger than the line width. Fixes long and futile
4093 looping inside extend_face_to_end_of_line (on a TTY) producing
4094 glyphs that are not needed and thrown away.
4096 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4098 * marker.c (set_marker_restricted_both): Simplify by using
4101 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4103 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4105 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4107 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4108 not defined (Bug#11768).
4109 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4110 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4111 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4112 followed by gtk_box_set_homogeneous (Bug#11768).
4113 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4114 (update_theme_scrollbar_width, xg_create_scroll_bar):
4115 Use gtk_scrollbar_new (Bug#11768).
4116 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4117 (is_box_type): New function (Bug#11768).
4118 (xg_tool_item_stale_p): Call is_box_type.
4119 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4120 with default display (Bug#11768).
4122 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4124 * xdisp.c (window_hscroll_limited): New function.
4125 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4126 coordinates when window's hscroll is set to insanely large
4129 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4131 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4132 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4134 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4137 * lisp.h (xzalloc): New prototype. Omit needless casts.
4138 * alloc.c (xzalloc): New function. Omit needless casts.
4139 * charset.c: Omit needless casts. Convert all calls to
4140 xmalloc with following memset to xzalloc.

4190 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4192 * fileio.c (time_error_value): Check the right error number.
4193 Problem reported by Troels Nielsen in
4194 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4196 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4198 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4199 This should be fixed in a better way; see Eli Zaretskii in
4200 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4201 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4203 * fileio.c (time_error_value): Rename from special_mtime.
4204 The old name's problems were noted by Eli Zaretskii in
4205 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4207 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4208 This variable's comment says Emacs needs at least one GDB-visible
4209 symbol of type enum pvec_type, to work around GDB problems.
4210 The symbol's value doesn't matter.
4212 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4213 that causes compilation to fail on pre-C99 compilers.
4215 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4217 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4218 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4220 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4222 * buffer.c (init_buffer_once): Fix initialization of
4223 headers for buffer_defaults and buffer_local_symbols.
4224 Reported by Juanma Barranquero <lekktu@gmail.com>.
4226 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4228 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4229 * lisp.h (enum pvec_type): Use fewer bits.
4230 (PSEUDOVECTOR_SIZE_BITS): New constant.
4231 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4232 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4233 change in pvec_type.
4234 (PSEUDOVECTOR_TYPEP): New macro.
4235 (TYPED_PSEUDOVECTORP): Use it.
4236 * fns.c (internal_equal): Adapt code to extract pvectype.
4237 * emacs.c (gdb_pvec_type): Update type.
4238 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4239 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4240 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4241 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4242 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4243 abusing vector->header.next.nbytes.
4244 (live_vector_p): Use PVEC_TYPE.
4245 (mark_object): Adapt code to extract pvectype. Use switch.
4247 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4249 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4250 Tighten new eassert a bit.
4252 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4254 Fix compilation with --enable-gcc-warnings and -O1
4256 * doprnt.c (doprnt): Change type of tem to int, initialize
4257 to avoid compiler warning. Add eassert.
4258 * search.c (simple_search): Initialize match_byte to avoid
4259 compiler warning. Add eassert.
4261 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4263 Avoid weird behavior with large horizontal scrolls.
4264 Without this change, for example, large hscroll values would
4265 mess up Emacs's display on Fedora 15 x86, presumably due to
4266 overflows in int calculations in the display code.
4267 Also, if buffers had long lines, Emacs would freeze.
4268 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4269 (set_window_hscroll): New function, containing the old guts of
4270 Fset_window_hscroll. Return the clipped value.
4271 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4272 This avoids the need to check against PTRDIFF_MAX.
4274 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4276 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4278 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4280 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4282 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4283 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4284 since GCC 4.4.6 issues a bogus warning for them.
4286 Fix bugs in file timestamp newness comparisons.
4287 * fileio.c (Ffile_newer_than_file_p):
4288 * lread.c (Fload): Use full timestamp resolution of files,
4289 not just the 1-second resolution, so that files that are only
4290 slightly newer still count as newer.
4291 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4292 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4294 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4296 * fileio.c: Improve handling of file time marker. (Bug#11852)
4297 (special_mtime): New function.
4298 (Finsert_file_contents, Fverify_visited_file_modtime):
4299 Use it to set special mtime values consistently.
4301 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4303 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4304 marker for non-existing file. (Bug#11852)
4306 2012-07-03 Glenn Morris <rgm@gnu.org>
4308 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4309 and did not make it into globals.h).
4311 2012-07-03 Tom Tromey <tromey@redhat.com>
4313 * window.c (Fset_window_margins, Fset_window_fringes)
4314 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4315 * textprop.c (Fprevious_property_change): No longer static.
4316 * syntax.c (Fsyntax_table_p): No longer static.
4317 * process.c (Fget_process, Fprocess_datagram_address): No longer

4331 * dired.c (Ffile_attributes): No longer static.
4332 * composite.c (Fcomposition_get_gstring): No longer static.
4333 * callproc.c (Fgetenv_internal): No longer static.
4335 * ccl.h: Remove EXFUNs.
4336 * buffer.h: Remove EXFUNs.
4337 * dispextern.h: Remove EXFUNs.
4338 * intervals.h: Remove EXFUNs.
4339 * fontset.h: Remove EXFUN.
4340 * font.h: Remove EXFUNs.
4341 * dosfns.c (system_process_attributes): Remove EXFUN.
4342 * keymap.h: Remove EXFUNs.
4343 * lisp.h: Remove EXFUNs.
4344 * w32term.h: Remove EXFUNs.
4345 * window.h: Remove EXFUNs.
4346 * xsettings.h: Remove EXFUN.
4347 * xterm.h: Remove EXFUN.
4349 2012-07-03 Glenn Morris <rgm@gnu.org>
4351 * lisp.h (Frandom): Make it visible to C.
4352 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4353 buffer for invisible buffers. (Bug#1229)
4355 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4357 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4358 values which aren't power of 2.
4359 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4360 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4363 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4365 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4367 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4369 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4371 * alloc.c (allocate_vector_block): Remove redundant
4372 calls to mallopt if DOUG_LEA_MALLOC is defined.
4373 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4374 avoid calls to mallopt if zero_vector is returned.
4376 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4378 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4379 is enabled, avoid dereferencing NULL current_sblock if
4382 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4384 Cleanup basic buffer management.
4385 * buffer.h (struct buffer): Change layout to use generic vector
4386 marking code. Fix some comments. Change type of 'clip_changed'
4387 to bitfield. Remove unused #ifndef old.
4388 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4389 (GET_OVERLAYS_AT): Fix indentation.
4390 (for_each_per_buffer_object_at): New macro.
4391 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4392 (Fbuffer_local_variables): Use it.
4393 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4394 * alloc.c (allocate_buffer): Adjust to match new layout of
4395 struct buffer. Fix comment.
4396 (mark_overlay): New function.
4397 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4398 Lisp area of struct buffer.
4399 (mark_object): Use it. Adjust marking of misc objects
4400 and related comments.
4402 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4404 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4405 wrapper that is not needed because the wrapped code is a no-op (zero
4406 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4407 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4409 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4411 * alloc.c (mark_buffer): Simplify. Remove prototype.
4412 (mark_object): Add comment. Reorganize marking of vector-like
4413 objects. Use CHECK_LIVE for all vector-like objects except buffers
4414 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4415 Avoid redundant calls to mark_vectorlike for bool vectors.
4417 2012-06-30 Glenn Morris <rgm@gnu.org>
4419 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4421 * epaths.in (PATH_SITELOADSEARCH): New.
4422 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4423 This is rather than relying on --enable-locallisppath elements
4424 having "site-lisp" in their names. (Bug#10208#25, 11658)
4426 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4428 * w32proc.c (sys_select): Accept and ignore one more argument.
4430 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4432 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4433 (pselect) [!MS_DOS]: Redirect to sys_select.
4435 * sysdep.c: Don't include dos.h and dosfns.h.
4437 * process.c (sys_select):
4438 * msdos.c (sys_select): Accept one more argument and ignore it.
4440 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4441 adapt data types and code to that.
4444 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4445 which clashes with the gnulib function of the same name.
4447 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4449 * font.c (font_style_to_value, font_style_symbolic)
4450 (font_prop_validate_style): Add type checks for values in
4453 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4455 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4458 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4460 * xdisp.c (try_window_id): Undo last change.
4462 * w32.c (getwd): Adjust commentary about startup_dir.
4463 (init_environment): Always call sys_access, even in non-MSVC
4464 builds. Don't chdir to the directory of the Emacs executable.
4465 This undoes code from 1997 which was justified by the need to
4466 "avoid conflicts when removing and renaming directories". But its
4467 downside was that every relative file name was being interpreted
4468 relative to the directory of the Emacs executable, which can never
4469 be TRT. In particular, it broke sys_access when called with
4470 relative file names.
4471 (sys_access): Map GetLastError to errno.
4473 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4475 * window.h (struct window): Change type of 'fringes_outside_margins'
4476 to bitfield. Fix comment. Adjust users accordingly.
4477 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
4479 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4482 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4484 * gnutls.c (emacs_gnutls_handshake):
4485 Add QUIT to make the loop interruptible.
4487 2012-06-29 Glenn Morris <rgm@gnu.org>
4489 * charset.c (init_charset): Make lack of etc/charsets fatal.
4491 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4493 * editfns.c (region_limit): Fix type mismatch.
4495 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4497 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4498 undefined. Convert from xassert to eassert.
4499 * nsmenu.m: Convert from xassert to eassert.

4665 Use sprintf return value instead of invoking strlen on result.
4666 In the old days this wasn't portable, since some sprintf
4667 implementations returned char *. But they died out years ago and
4668 Emacs already assumes sprintf returns int.
4669 Similarly for float_to_string.
4670 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

4678 Use sprintf or float_to_string result to avoid need to call strlen.
4679 * data.c (Fnumber_to_string):
4680 Use make_unibyte_string, since the string must be ASCII.
4681 * lisp.h, print.c (float_to_string): Now returns int length.
4682 * term.c (produce_glyphless_glyph):
4683 Use sprintf result rather than recomputing it.
4685 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
4686 * Makefile.in (ALL_CFLAGS):
4687 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

4716 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
4718 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

4721 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
4723 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
4724 instead of truncating it to 63 (admittedly a generous limit).

4784 * keyboard.c (kbd_buffer_get_event):
4785 * process.c (Faccept_process_output):
4786 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
4787 This improves on the previous patch, which introduced a bug
4788 when time_t is unsigned and as wide as intmax_t.
4789 See <http://bugs.gnu.org/9000#51>.
4791 2012-06-23 Eli Zaretskii <eliz@gnu.org>

4854 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
4856 Support higher-resolution time stamps (Bug#9000).
4857 The time stamps are only nanosecond-resolution at the C level,
4858 since that's the best that any real-world system supports now.
4859 But they are picosecond-resolution at the Lisp level, as that's
4860 easy, and leaves room for future OS improvements.
4862 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
4865 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
4866 Don't get current time unless it's needed.
4868 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
4869 now provides it if it's absent.
4870 (start_atimer): Port to higher-res time stamps.
4871 Check for time stamp overflow. Don't get current time more
4872 often than is needed.
4874 * buffer.h (struct buffer): Buffer modtime now has high resolution.
4875 Include systime.h, not time.h.
4876 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
4878 * dired.c: Include stat-time.h.
4879 (Ffile-attributes): File times now have higher resolution.

4882 (struct image): Timestamp now has higher resolution.
4884 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
4885 has at least microseconds now. All uses removed.
4886 (update_frame, update_single_window, update_window, update_frame_1)
4887 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
4888 (duration_to_sec_usec): Remove; no longer needed.
4890 * editfns.c (time_overflow): Now extern.
4891 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
4892 (float-time, Fformat_time_string, Fcurrent_time_string)

4896 (decode_time_components, lisp_seconds_argument): New functions.
4897 (make_time): Now static.
4898 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
4899 Report an error if the time is invalid, rather than having the caller
4902 * fileio.c: Include <stat-time.h>
4903 (Fcopy_file): Copy higher-resolution time stamps.
4904 Prefer to set the time stamp via a file descriptor if that works.
4905 (Fset_file_times, Finsert_file_contents, Fwrite_region)
4906 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
4907 (Fvisited_file_modtime, Fset_visited_file_modtime):
4908 Support higher-resolution time stamps.
4910 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
4912 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
4914 * image.c (prepare_image_for_display, clear_image_cache)
4915 (lookup_image): Port to higer-resolution time stamps.
4917 * keyboard.c (start_polling, bind_polling_period):
4918 Check for time stamp overflow.
4919 (read_char, kbd_buffer_get_event, timer_start_idle)
4920 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
4921 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
4922 Port to higher-resolution time stamps. Do not assume time_t is signed.
4923 (decode_timer): New function. Timers are now vectors of length 9,
4924 not 8, to accommodate the picosecond component.
4925 (timer_check_2): Use it.
4927 * nsterm.m (select_timeout, timeval_subtract): Remove.
4928 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
4929 as they're a bit more accurate and handle overflow better.
4930 (ns_select): Change prototype to be compatible with pselect.
4931 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
4932 * nsterm.h (ns_select): Adjust prototype.
4934 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
4935 us-resolution time stamps.
4936 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
4938 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
4940 * lisp.h (time_overflow): New decl.
4941 (wait_reading_process_output): First arg is now intmax_t, not int,
4942 to accommodate larger waits.
4944 * process.h (struct Lisp_Process.read_output_delay):
4945 Now counts nanoseconds, not microseconds.
4946 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
4948 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
4949 (wait_reading_process_output):
4950 Port to ns-resolution time stamps.
4951 (Faccept_process_output, wait_reading_process_output):
4952 Check for time stamp overflow. Do not assume time_t is signed.
4953 (select_wrapper): Remove; we now use pselect.
4954 (Fprocess_attributes): Now generates ns-resolution time stamps.
4956 * sysdep.c: Include utimens.h. Don't include utime.h
4957 or worry about struct utimbuf; gnulib does that for us now.
4958 (gettimeofday): Remove; gnulib provides a substitute.
4959 (make_timeval): New function.
4960 (set_file_times): Now sets ns-resolution time stamps.
4961 New arg FD; all uses changed.
4962 (time_from_jiffies, ltime_from_jiffies, get_up_time)
4963 (system_process_attributes):
4964 Now returns ns-resolution time stamp. All uses changed.
4965 Check for time stamp overflow.
4967 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
4968 provides a substitute now.
4970 * systime.h: Include timespec.h rather than sys/time.h and time.h,
4971 since it guarantees struct timespec.
4972 (EMACS_TIME): Now struct timespec, so that we can support
4973 ns-resolution time stamps.
4974 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4975 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4976 (EMACS_USECS): Remove.
4977 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4978 so multiply the arg by 1000 before storing it.
4979 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
4981 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
4982 Port to ns-resolution time stamps.
4983 (EMACS_TIME_NEG_P): Remove; replaced by....
4984 (EMACS_TIME_SIGN): New macro.
4985 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)

4988 (make_timeval, make_lisp_time, decode_time_components): New decls.
4989 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

5031 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5032 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

5084 gets killed during executing of this function (Bug#11665).

5455 would mishandle a string argument "Xc" if X was a multibyte
5456 character of length 2: it would truncate after X's first byte
5457 rather than including all of X.
5459 2012-06-06 Chong Yidong <cyd@gnu.org>
5461 * buffer.c (word_wrap): Doc fix.
5463 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
5465 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.
5467 2012-06-03 Glenn Morris <rgm@gnu.org>

5474 (temacs$(EXEEXT)): Disable memory randomization for the temacs
5475 binary via PaX flags if the paxctl utility is available.
5476 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5477 Restore PaX flags to their default. (Bug#11398)
5479 2012-06-03 Chong Yidong <cyd@gnu.org>
5481 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
5484 2012-06-03 Chong Yidong <cyd@gnu.org>
5486 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5487 (note_mode_line_or_margin_highlight): If there is no help echo,
5488 use mode-line-default-help-echo. Handle the case where the mouse
5489 position is past the end of the mode line string.
5491 * buffer.c (buffer_local_value_1): New function, split from
5492 Fbuffer_local_value; can return Qunbound.
5493 (Fbuffer_local_value): Use it.
5494 (Vmode_line_format): Docstring tweaks.
5496 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5498 * sysdep.c (system_process_attributes): Improve comment.
5500 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
5502 * keyboard.c: Export real-this-command to Elisp.
5503 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5504 and DEFVAR it. Update all users.
5506 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5508 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5510 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5511 Convert pctcpu and pctmem to Lisp float properly.
5512 Let the compiler fold better, as 100.0/0x8000 is exact.
5514 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5516 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5519 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5521 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5523 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5525 For a 'struct window', replace some Lisp_Object fields to
5526 bitfields where appropriate, remove unused fields.
5527 * window.h (struct window): Remove unused 'last_mark_x' and
5528 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5529 change it's type from Lisp_Object to bitfield.
5530 Change type of 'force_start', 'optional_new_start',
5531 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5532 fields from Lisp_Object to bitfield. Adjust users accordingly.
5534 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5536 Pacify gcc -Wdouble-precision when using Xaw.
5537 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5538 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5539 Use 'float' consistently, rather than 'float' in most places
5540 and 'double' in a couple of places.
5542 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5544 * xdisp.c (handle_stop): Detect whether we have overlay strings
5545 loaded by testing it->current.overlay_string_index to be
5546 non-negative, instead of checking whether n_overlay_strings is
5547 positive. (Bug#11587)
5549 2012-05-31 Chong Yidong <cyd@gnu.org>
5551 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5553 * doc.c (Fsubstitute_command_keys): Doc fix.
5555 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5557 * search.c (search_buffer): Remove calls to
5558 r_alloc_inhibit_buffer_relocation, as it is now called by
5559 maybe_unify_char, which was the cause of relocation of buffer text
5562 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5564 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5565 for the duration of call to load_charset, to avoid problems with
5566 callers of maybe_unify_char that access buffer text through C
5569 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5570 decrement the inhibition flag, instead of just setting or
5573 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5575 Remove obsolete '#define static' cruft.
5576 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5577 This #undef was "temporary" in 2000; it is no longer needed
5578 now that '#define static' has gone away.
5579 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5580 (gray_bitmap_bits): Remove; no longer needed.
5581 All uses replaced with definiens.
5582 * xterm.c: Include "bitmaps/gray.xbm".
5584 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5586 Clean up __executable_start, monstartup when --enable-profiling.
5587 The following changes affect the code only when profiling.
5588 * dispnew.c (__executable_start): Rename from safe_bcopy.
5589 Define only on platforms that need it.
5590 * emacs.c: Include <sys/gmon.h> when profiling.
5591 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5592 (__executable_start): Remove decl, since lisp.h does it now.
5593 (safe_bcopy): Remove decl; no longer has that name.
5594 (main): Coalesce #if into single bit of code, for simplicity.
5595 Cast pointers to uintptr_t, since standard libraries want integers
5597 * lisp.h (__executable_start): New decl.
5599 2012-05-31 Glenn Morris <rgm@gnu.org>
5601 * image.c (Fimagemagick_types): Doc fix.
5603 2012-05-30 Jim Meyering <meyering@redhat.com>
5605 * callproc.c (Fcall_process_region): Include directory component
5606 in mkstemp error message (Bug#11586).
5608 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5610 * alloc.c, lisp.h (make_pure_vector): Now static.
5612 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

5615 Move to byte-run.el.
5616 (Fautoload): Do the hash-doc more carefully.
5617 * data.c (Fdefalias): Purify definition, except for keymaps.
5618 (Qdefun): Move from eval.c.
5619 * lisp.h (Qdefun): Remove.
5620 * lread.c (read1): Tiny simplification.
5622 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
5624 Do not create empty overlays with the evaporate property (Bug#9642).
5625 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
5626 Bug#9642, but explicitly check that the buffer the overlay would
5627 be moved to is live and rearrange lines to make sure that errors
5628 will not put the overlay in an inconsistent state.
5629 (Fdelete_overlay): Cosmetics.
5631 2012-05-28 Eli Zaretskii <eliz@gnu.org>
5633 * w32term.c (my_bring_window_to_top): New function.
5634 (x_raise_frame): Use handle returned by DeferWindowPos, which
5635 could be different from the original one.
5636 Call my_bring_window_to_top instead of my_set_foreground_window.
5639 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
5640 by calling BringWindowToTop.
5642 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
5643 (WM_EMACS_END): Increase by one.
5645 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
5647 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
5648 This avoids undefined behavior that might cause the eassert
5649 to not catch an out-of-range value.
5651 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
5653 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
5654 Update dependencies.
5656 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5658 * bidi.c (bidi_mirror_char): Fix last change.
5660 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
5662 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
5663 when referring to sectname field in printf format.
5665 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
5667 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
5668 Only r_alloc_inhibit_buffer_relocation needed to be added;
5669 the others were already declared.
5671 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
5672 before checking whether it's out of range. Put the check inside
5674 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
5676 2012-05-27 Ken Brown <kbrown@cornell.edu>
5678 * callproc.c (Fcall_process): Restore a line that was accidentally
5679 commented out in the 2011-02-13 change (bug#11547).
5681 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5683 * lisp.h [REL_ALLOC]: Add prototypes for external functions
5684 defined on ralloc.c.
5686 * buffer.c [REL_ALLOC]: Remove prototypes of
5687 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
5688 they are now on lisp.h.
5690 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
5692 * search.c (search_buffer): Use it to inhibit relocation of buffer
5693 text while re_search_2 is doing its job, because re_search_2 is
5694 passed C pointers to buffer text. (Bug#11519)
5696 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
5699 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
5700 state after an additional call to move_it_in_display_line_to, keep
5701 the values of it->max_ascent and it->max_descent found for the
5703 (pos_visible_p): Revert the comparison against bottom_y to what it
5704 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
5707 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5709 Fix coding-related core dumps with gcc -ftrapv.
5710 The code was computing A - B, where A and B are pointers, and B is
5711 random garbage. This can lead to core dumps on platforms that
5712 have special pointer registers, and it also leads to core dumps on
5713 x86-64 when compiled with gcc -ftrapv. The fix is to compute
5714 A - B only when B is initialized properly.
5715 * coding.c (coding_set_source, coding_set_destination): Return void.
5716 (coding_change_source, coding_change_destinations): New functions,
5717 with the old behaviors of coding_set_source and coding_set_destination.
5718 All callers that need an offset changed to use these new functions.
5720 2012-05-26 Glenn Morris <rgm@gnu.org>
5722 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
5724 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5726 Extend mouse support on W32 text-mode console.
5727 * xdisp.c (draw_row_with_mouse_face):
5728 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
5730 * w32console.c: Include window.h.
5731 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
5733 (initialize_w32_display): Initialize mouse-highlight data.
5735 * w32inevt.c: Include termchar.h and window.h.
5736 (do_mouse_event): Support mouse-autoselect-window. When the mouse
5737 moves, call note_mouse_highlight. If help_echo changed, call
5738 gen_help_event to produce help-echo message in the echo area.
5739 Call clear_mouse_face if mouse_face_hidden is set in the mouse
5742 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5744 * lread.c (read1): Simplify slightly to avoid an overflow warning
5745 with GCC 4.7.0 on x86-64.
5747 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5749 * bidi.c (bidi_mirror_char): Revert last change: an int is
5750 definitely wide enough here.
5752 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
5754 Fix integer width and related bugs (Bug#9874).
5755 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
5756 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
5757 (string_bytes, check_sblock, allocate_string_data):
5758 (compact_small_strings, Fmake_bool_vector, make_string)
5759 (make_unibyte_string, make_multibyte_string)
5760 (make_string_from_bytes, make_specified_string)
5761 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
5762 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
5764 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5765 (allocate_pseudovector):
5766 Use int, not EMACS_INT, where int is wide enough.
5767 (inhibit_garbage_collection, Fgarbage_collect):
5768 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5769 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
5770 int might not be wide enough.
5771 (bidi_cache_search, bidi_cache_find, bidi_init_it)
5772 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5773 (bidi_at_paragraph_end, bidi_find_paragraph_start)
5774 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
5775 (bidi_level_of_next_char, bidi_move_to_visually_next):
5776 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5777 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
5778 (Fkill_buffer, Fset_buffer_major_mode)
5779 (advance_to_char_boundary, Fbuffer_swap_text)
5780 (Fset_buffer_multibyte, overlays_at, overlays_in)
5781 (overlay_touches_p, struct sortvec, record_overlay_string)
5782 (overlay_strings, recenter_overlay_lists)
5783 (adjust_overlays_for_insert, adjust_overlays_for_delete)
5784 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
5785 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
5786 (Foverlay_recenter, last_overlay_modification_hooks_used)
5787 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
5788 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5789 (validate_region): Omit unnecessary test for b <= e,
5790 since that's guaranteed by the previous test.
5791 (adjust_overlays_for_delete): Avoid pos + length overflow.
5792 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
5793 (report_overlay_modification):
5794 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5795 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
5796 Omit pointer cast, which isn't needed anyway, and doesn't work
5797 after the EMACS_INT -> ptrdiff_t change.
5798 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
5799 * buffer.h: Adjust decls to match defn changes elsewhere.
5800 (struct buffer_text, struct buffer):
5801 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5802 Use EMACS_INT, not int, where int might not be wide enough.
5803 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
5804 not int, to avoid needless 32-bit limit on 64-bit hosts.
5805 (exec_byte_code): Use tighter memory-full test, one that checks
5806 for alloca overflow. Don't compute the address of the object just
5807 before an array, as that's not portable. Use EMACS_INT, not
5808 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
5809 * callint.c (Fcall_interactively):
5810 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5811 * callproc.c (call_process_kill, Fcall_process):
5812 Don't assume pid_t fits into an Emacs fixnum.
5813 (call_process_cleanup, Fcall_process, child_setup):
5814 Don't assume pid_t fits into int.
5815 (call_process_cleanup, Fcall_process, delete_temp_file)
5816 (Fcall_process_region):
5817 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5818 (Fcall_process): Simplify handling of volatile integers.
5819 Use int, not EMACS_INT, where int will do.
5820 * casefiddle.c (casify_object, casify_region, operate_on_word)
5821 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
5822 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5823 (casify_object): Avoid integer overflow when overallocating buffer.
5824 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
5825 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
5826 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
5827 * category.h (CATEGORYP): Don't assume arg is nonnegative.
5828 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
5829 integers are now checked earlier. All uses replaced with XINT.
5831 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5832 For CCL_MapSingle, check that content and value are in int range.
5833 (ccl_driver, Fregister_code_conversion_map):
5834 Check that Vcode_version_map_vector is a vector.
5835 (resolve_symbol_ccl_program): Check that vector header is in range.
5836 Always copy the vector, so that we can check its contents reliably
5837 now rather than having to recheck each instruction as it's being
5838 executed. Check that vector words fit in 'int'.
5839 (ccl_get_compiled_code, Fregister_ccl_program)
5840 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
5841 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
5842 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
5843 contents are in range.
5844 (Fccl_execute_on_string): Check that status is in range.
5845 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
5846 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
5847 Accept and return EMACS_INT, not int, because callers can pass values
5849 (c_string_width, strwidth, lisp_string_width, chars_in_text)
5850 (multibyte_chars_in_text, parse_str_as_multibyte)
5851 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
5852 (str_as_unibyte, str_to_unibyte, string_count_byte8)
5853 (string_escape_byte8, Fget_byte):
5854 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5855 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
5856 avoid mishandling large integers.
5857 * character.h: Adjust decls to match defn changes elsewhere.
5858 * charset.c (load_charset_map_from_file, find_charsets_in_text)
5859 (Ffind_charset_region):
5860 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5861 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
5862 (load_charset_map_from_vector, Fdefine_charset_internal):
5863 Don't assume fixnum fits in int.
5864 (load_charset_map_from_vector, Fmap_charset_chars):
5865 Remove now-unnecessary CHECK_NATNUMs.
5866 (Fdefine_charset_internal): Check ranges here, more carefully.
5867 Don't rely on undefined behavior with signed left shift overflow.
5868 Don't assume unsigned int fits into fixnum, or that fixnum fits
5869 into unsigned int. Don't require max_code to be a valid fixnum;
5870 that's not true for gb10830 4-byte on a 32-bit host. Allow
5871 invalid_code to be a cons, for the same reason. Require code_offset
5872 to be a character. Avoid int overflow if max_char is close
5874 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
5875 this is intended anyway and avoids some undefined behavior.
5876 (load_charset_map): Pass unsigned, not int, as 2nd arg of
5877 INDEX_TO_CODE_POINT, as that's what it expects.
5878 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
5879 * charset.h (DECODE_CHAR): Return int, not unsigned;
5880 this is what was intended anyway, and it avoids undefined behavior.
5881 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
5882 integer-overflow issues.
5883 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
5884 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
5885 where the argument is EMACS_INT, and this behavior is not intended.
5886 * chartab.c (Fmake_char_table, Fset_char_table_range)
5887 (uniprop_get_decoder, uniprop_get_encoder):
5888 Don't assume fixnum fits in int.
5889 * cmds.c (move_point): New function, that does the gist of
5890 Fforward_char and Fbackward_char, but does so while checking
5891 for integer overflow more accurately.

6602 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
6603 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
6604 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
6605 * s/ms-w32.h (DATA_START):
6606 Move here from removed file m/intel386.h.
6607 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
6608 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
6610 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
6612 Assume C89 or later.
6613 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
6614 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
6616 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
6617 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
6618 * textprop.c, tparam.c (NULL): Remove.
6619 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
6620 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
6621 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
6622 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
6623 * xterm.c (input_signal_count): Assume volatile works.
6625 2012-05-21 Ken Brown <kbrown@cornell.edu>
6627 * xgselect.c (xg_select): Fix first argument in call to 'select'
6630 2012-05-20 Ken Brown <kbrown@cornell.edu>
6632 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
6633 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
6635 2012-05-19 Ken Brown <kbrown@cornell.edu>
6637 * xfns.c (x_in_use): Remove `static' qualifier.
6638 * xterm.h (x_in_use): Declare.
6639 * xgselect.c: Include xterm.h.
6640 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
6641 and `display_arg' (bug#9754).
6643 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
6645 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
6647 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
6648 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
6650 2012-05-18 Eli Zaretskii <eliz@gnu.org>
6652 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
6654 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
6655 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
6657 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
6658 reference to image_cache->refcount.
6659 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
6661 2012-05-17 Juri Linkov <juri@jurta.org>
6663 * search.c (Fword_search_regexp, Fword_search_backward)
6664 (Fword_search_forward, Fword_search_backward_lax)
6665 (Fword_search_forward_lax): Move functions to isearch.el
6666 (bug#10145, bug#11381).
6668 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
6670 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
6672 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
6674 * lread.c (init_obarray): Declare Qt and Qnil as special.
6676 2012-05-14 Glenn Morris <rgm@gnu.org>
6678 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
6679 Put "libexec" before "bin", for the sake of init_callproc_1.
6681 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6683 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
6685 * unexaix.c: Port to more-recent AIX compilers.
6686 (report_error, report_error_1, make_hdr, copy_sym)
6687 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
6688 Make arguments const char *, not char *, to avoid violations of C
6689 standard and to fix some AIX warnings reported by Gilles Pion.
6691 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6693 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
6694 already have overlays loaded.
6695 (handle_single_display_spec): Before returning without displaying
6696 fringe bitmap, synchronize the bidi iterator with the main display
6697 iterator, by calling iterate_out_of_display_property.
6698 (iterate_out_of_display_property): Detect buffer iteration by
6699 testing that it->string is a Lisp string.
6700 (get_next_display_element): When the current object is exhausted,
6701 and there's something on it->stack, call set_iterator_to_next to
6702 proceed with what's on the stack, instead of returning zero.
6703 (set_iterator_to_next): If called at the end of a Lisp string,
6704 proceed to consider_string_end without incrementing string
6705 position. Don't increment display vector index past the end of
6706 the display vector. (Bug#11417)
6707 (pos_visible_p): Don't report a position visible when move_it_to
6708 stopped at the last line of window, which happens to be scanned
6709 backwards by the bidi iteration. (Bug#11464)
6711 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6713 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
6714 and right-margin display specs even if the spec is invalid or we
6715 are on a TTY, and thus unable to display on the fringes.
6716 That's because the text with the property will not be displayed anyway,
6717 so we need to signal to the caller that this is a "replacing"
6718 display spec. This fixes display when the spec is invalid or we
6721 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6723 * unexaix.c (make_hdr): Fix typo in prototype.
6724 This bug broke the build on AIX. Problem reported by Gilles Pion.
6726 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
6728 * keyboard.c (kbd_buffer_get_event): Read special events also in
6729 batch mode. (Bug#11415)
6731 2012-05-12 Glenn Morris <rgm@gnu.org>
6733 * ns.mk: Update for ns_appbindir no longer having trailing "/".
6735 2012-05-12 Eli Zaretskii <eliz@gnu.org>
6737 * lisp.mk (lisp): Add newcomment.elc.
6739 2012-05-12 Glenn Morris <rgm@gnu.org>
6741 * Makefile.in (MKDIR_P): New, set by configure.
6742 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
6744 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
6746 Remove unused function hourglass_started.
6747 * dispextern.h (hourglass_started):
6748 * w32fns.c (hourglass_started):
6749 * xdisp.c (hourglass_started): Remove.
6751 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
6753 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
6754 Update dependencies.
6756 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
6758 * xgselect.c (xg_select): Put maxfds+1 into a var.
6759 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
6761 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
6763 2012-05-10 Dave Abrahams <dave@boostpro.com>
6765 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
6766 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
6768 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
6770 * dbusbind.c (xd_registered_buses): New internal Lisp object.
6771 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
6772 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
6773 Initialize xd_registered_buses.
6775 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
6777 Untag more efficiently if USE_LSB_TAG.
6778 This is based on a proposal by YAMAMOTO Mitsuharu in
6779 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
6780 For an admittedly artificial (nth 8000 longlist) benchmark on
6781 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
6782 Emacs's overall text size by 1%.
6783 * lisp.h (XUNTAG): New macro.
6784 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
6785 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
6786 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
6787 * eval.c (Fautoload):
6788 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
6789 * frame.h (XFRAME): Use XUNTAG.
6791 Port recent dbusbind.c changes to 32-bit --with-wide-int.
6792 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
6793 Remove unportable assumptions about print widths of types like
6795 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
6796 intptr_t when converting between pointer and integer, to avoid GCC
6797 warnings about wrong width.
6799 2012-05-09 Eli Zaretskii <eliz@gnu.org>
6801 * w32proc.c (new_child): Force Windows to reserve only 64KB of
6802 stack for each reader_thread, instead of defaulting to 8MB
6803 determined by the linker. This avoids failures in creating
6804 subprocesses on Windows 7, see the discussion in this thread:
6805 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
6807 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
6809 Fix up display of the *Minibuf-0* buffer in the mini window.
6810 * keyboard.c (read_char): Don't clear the echo area if there's no
6812 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
6813 contents of *Minibuf-0*) if there's no message displayed in its stead.
6815 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
6817 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
6820 2012-05-06 Chong Yidong <cyd@gnu.org>
6822 * lisp.mk (lisp): Update.
6824 2012-05-05 Jim Meyering <meyering@redhat.com>
6826 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
6828 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
6830 * data.c (PUT_ERROR): New macro.
6831 (syms_of_data): Use it. Add new error type `user-error'.
6832 * undo.c (user_error): New function.
6833 (Fprimitive_undo): Use it.
6834 * print.c (print_error_message): Adjust print style for `user-error'.
6835 * keyboard.c (user_error): New function.
6836 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
6838 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
6840 Do not limit current-time-string to years 1000..9999.
6841 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
6842 (Fcurrent_time_string): Support any year that is supported by the
6843 underlying localtime representation. Don't use asctime, as it
6844 has undefined behavior for years outside the range -999..9999.
6846 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
6848 Fix race conditions involving setenv, gmtime, localtime, asctime.
6849 Without this fix, interrupts could mess up code that uses these
6850 nonreentrant functions, since setting TZ invalidates existing
6851 tm_zone or tzname values, and since most of these functions return
6852 pointers to static storage.
6853 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
6854 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
6855 Grow the critical sections to include not just invoking
6856 localtime/gmtime, but also accessing these functions' results
6857 including their tm_zone values if any, and any related TZ setting.
6858 (format_time_string): Last arg is now struct tm *, not struct tm **,
6859 so that the struct tm is saved in the critical section.
6860 All callers changed. Simplify allocation of initial buffer, partly
6861 motivated by the fact that memory allocation needs to be outside
6862 the critical section.
6864 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
6866 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
6867 with RESET_INTERVAL.
6869 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
6870 Remove duplicated buffer name initialization.
6872 2012-05-02 Jim Meyering <jim@meyering.net>
6874 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
6876 * xfns.c (x_window): Use xstrdup (Bug#11375).
6878 2012-05-02 Eli Zaretskii <eliz@gnu.org>
6880 * xdisp.c (pos_visible_p): If already at a newline from the
6881 display string before the 'while' loop, don't walk back the glyphs
6882 from it3.glyph_row. Solves assertion violation when the display
6883 string begins with a newline (egg.el). (Bug#11367)
6885 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
6887 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
6890 2012-05-01 Glenn Morris <rgm@gnu.org>
6892 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
6893 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
6894 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
6895 All were removed before 23.1.
6897 * dispnew.c: Remove HAVE_LIBNCURSES test;
6898 it is always true on relevant platforms.
6900 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
6901 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
6903 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
6905 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
6907 * .gdbinit (xpr): Remove checks for no longer existing misc types.
6908 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
6911 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
6913 Do not avoid creating empty evaporating overlays (Bug#9642).
6914 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
6915 That is, do not delete an evaporating overlay if it becomes
6916 empty after its bounds are adjusted to fit within its buffer.
6917 This fix caused other problems, and I'm reverting it until we get
6918 to the bottom of them.
6920 2012-04-27 Chong Yidong <cyd@gnu.org>
6922 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
6924 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6926 * xdisp.c (pos_visible_p): If the window start position is beyond
6927 ZV, start the display from buffer beginning. Prevents assertion
6928 violation in init_iterator when the minibuffer window is scrolled
6931 * window.c (window_scroll_pixel_based): Likewise.
6933 2012-04-27 Chong Yidong <cyd@gnu.org>
6935 * keymap.c (where_is_internal): Doc fix (Bug#10872).
6937 2012-04-27 Glenn Morris <rgm@gnu.org>
6939 * fileio.c (Fcopy_file, Fset_file_selinux_context):
6940 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
6942 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6944 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
6945 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
6947 2012-04-26 Eli Zaretskii <eliz@gnu.org>
6949 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
6950 display element, check also the underlying string or buffer
6951 character. (Bug#11341)
6953 * w32menu.c: Include w32heap.h.
6954 (add_menu_item): If the call to AppendMenuW (via
6955 unicode_append_menu) fails, disable Unicode menus only if we are
6956 running on Windows 9X/Me.
6958 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6960 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6961 (xgetint): Add missing shift for LSB tags.
6963 2012-04-24 Martin Rudalics <rudalics@gmx.at>
6965 * keyboard.c (read_char): Don't wipe echo area for select window
6966 events: These might get delayed via `mouse-autoselect-window'
6969 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
6971 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
6972 manipulation of :loaded-from data.
6974 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6976 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6977 now a cons (bug#11311).
6979 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
6981 Do not create empty overlays with the evaporate property (Bug#9642).
6982 * buffer.c (Fmove_overlay): Delete an evaporating overlay
6983 if it becomes empty after its bounds are adjusted to fit within
6984 its buffer. Without this fix, in a nonempty buffer (let ((o
6985 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
6986 yields an empty overlay that has the evaporate property, which is
6987 not supposed to happen.
6989 Fix minor GTK3 problems found by static checking.
6990 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
6991 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6992 (struct _EmacsFixedClass, emacs_fixed_get_type):
6993 Move decls here from emacsgtkfixed.h, since they needn't be public.
6994 (emacs_fixed_get_type): Now static.
6995 (emacs_fixed_class_init): Omit unused local.
6996 (emacs_fixed_child_type): Remove; unused.

6998 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6999 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7000 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7001 (EMACS_FIXED_GET_CLASS): Remove; unused.
7002 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7004 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7005 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7007 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7009 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7010 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7011 (__malloc_size_t, __malloc_ptrdiff_t):
7012 Remove. All uses removed, replaced by the definiens if needed,
7013 since we can assume C89 or better now.
7014 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7015 (protect_malloc_state, align, get_contiguous_space)
7016 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7017 (malloc_atfork_handler_child, malloc_enable_thread)

7022 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7023 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7024 Define using prototypes, not old style.
7025 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7026 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7027 (align): Don't assume that signed integer overflow wraps around.
7028 Omit unused local var.
7029 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7030 (_free_internal_nolock, memalign, mallochook, reallochook):
7031 Omit no-longer-needed casts.
7032 (valloc): Use getpagesize, not __getpagesize.
7033 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7034 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7036 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7038 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7040 Move functions from C to Lisp. Make non-blocking method calls
7041 the default. Implement further D-Bus standard interfaces.
7043 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7044 (QCdbus_request_name_allow_replacement)
7045 (QCdbus_request_name_replace_existing)
7046 (QCdbus_request_name_do_not_queue)

7050 (QCdbus_request_name_reply_already_owner): Move to dbus.el.
7051 (QCdbus_registered_serial, QCdbus_registered_method)
7052 (QCdbus_registered_signal): New Lisp objects.
7053 (XD_DEBUG_MESSAGE): Use sizeof.

7089 * alloc.c: Handle unusual debugging option combinations.
7090 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7091 since the two debugging options are incompatible.
7092 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7094 (mem_init, mem_insert, mem_insert_fixup):
7095 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7127 (print_object): Check for cycles even when print-circle is nil and
7128 print-gensym is t, but only check print_depth if print-circle is nil.
7130 2012-04-20 Chong Yidong <cyd@gnu.org>
7132 * process.c (wait_reading_process_output): If EIO occurs on a pty,

7188 New extern decls, to avoid calling undeclared functions.
7189 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7190 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7191 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

7232 Remove definition of GC_MARK_STACK, since the default now works.
7233 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7234 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7235 no longer the default.
7236 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7238 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7261 2012-04-11 Daniel Colascione <dancol@dancol.org>
7263 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7264 against is gone. It's better to use vfork now so that when Cygwin
7265 gains a new, working vfork, we use it automatically (bug#10398).
7267 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7288 being loaded (bug#10424).
7290 2012-04-09 Glenn Morris <rgm@gnu.org>
7292 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7293 not just in the obarray, before snarfing them. (Bug#11036)

7320 * minibuf.c (Fread_variable): Callers changed.
7322 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7324 * xdisp.c (set_cursor_from_row): If the display string appears in
7325 the buffer at position that is closer to point than the position
7326 after the display string, display the cursor on the first glyph of
7327 the display string. Fixes cursor display when a 'display' text
7328 property immediately follows invisible text. (Bug#11094)
7330 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7332 composite.c: use 'double' consistently
7333 * composite.c (get_composition_id): Use 'double' consistently
7334 instead of converting 'float' to 'double' and vice versa; this is
7335 easier to understand and avoids a GCC warning.
7337 2012-04-09 Glenn Morris <rgm@gnu.org>
7339 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7340 preparation for dumping it with emacs. (Bug#4789)

7362 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7363 (mark_memory): Mark Lisp_Objects only if pointers might hide in

7382 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7383 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7384 [!WINDOWSNT]: New macros.
7385 (init_libxml2_functions, libxml2_loaded_p): New functions.
7386 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7387 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7388 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7389 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7391 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7392 Call init_libxml2_functions before calling libxml2 functions.
7393 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7395 * emacs.c: Don't include libxml/parser.h.

7397 xmlCleanupParser directly.
7399 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7401 2012-04-07 Eli Zaretskii <eliz@gnu.org>

7409 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7410 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7411 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7412 macros related to unification of CJK characters. For the details,
7413 see the discussion following the message here:
7414 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7416 2012-04-04 Chong Yidong <cyd@gnu.org>
7418 * keyboard.c (Vdelayed_warnings_list): Doc fix.

7430 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7432 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7433 position we get to after a call to move_it_to fails the
7434 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7435 only if we wind up in a string from display property. (Bug#11063)
7437 * window.c (Fdelete_other_windows_internal): Invalidate the row
7438 and column information about mouse highlight, so that redisplay
7439 restores it after reallocating the glyph matrices. (Bug#7464)
7441 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7442 string comes from a `display' text property, use the buffer
7443 position of that property as if we actually saw that position in
7445 (move_it_by_lines): Remove the assertion that
7446 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7447 violated when there's a before-string at the beginning of a line.
7450 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7452 * xdisp.c (append_space_for_newline): If the default face was
7453 remapped, use the remapped face for the appended newline.
7454 (extend_face_to_end_of_line): Use the remapped default face for
7455 extending the face to the end of the line.
7456 (display_line): Call extend_face_to_end_of_line when the default
7457 face was remapped. (Bug#11068)
7459 2012-03-29 Eli Zaretskii <eliz@gnu.org>

7481 handle-select-window too (Bug#8996).
7483 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7485 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

7489 * dispextern.h (struct glyph): Change the bit length of
7490 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7492 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7494 * s/ms-w32.h (tzname): Include time.h before redirecting to

7505 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7507 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7508 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7509 when fetching a multibyte character consumes more bytes than
7510 CHAR_BYTES returns, due to unification of CJK characters in
7511 string_char. (Bug#11073)
7513 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7515 * process.c (wait_reading_process_output): Handle pty disconnect
7516 by refraining from sending oneself a SIGCHLD (bug#10933).

7539 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
7540 to reflect default non-nil value of redisplay-dont-pause.
7542 2012-03-19 Kenichi Handa <handa@m17n.org>
7544 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
7545 it fit in a valid range (Bug#11003).
7547 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7549 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7550 that is not from display property, accept the row as a "cursor
7551 row" if one of the string's character has a non-nil `cursor'
7552 property. Fixes cursor positioning when there are newlines in
7553 overlay strings, e.g. in icomplete.el. (Bug#11035)
7555 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

7586 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7589 2012-03-03 Glenn Morris <rgm@gnu.org>
7591 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

7604 * buffer.c (buffer-list-update-hook): Doc fix.
7606 2012-02-29 Eli Zaretskii <eliz@gnu.org>

7609 push_it before setting up the iterator for the first overlay
7610 string, even if we have an empty string loaded.
7611 (next_overlay_string): If there's an empty string on the iterator
7612 stack, pop the stack. (Bug#10903)
7614 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
7616 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
7617 Suggested by Stefan Monnier in
7618 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
7619 * alloc.c (widen_to_Lisp_Object): New static function.
7620 (mark_memory): Also mark Lisp_Objects by fetching pointer words
7621 and widening them to Lisp_Objects. This would work even if
7622 USE_LSB_TAG is defined and wide integers are used, which might
7623 happen in a future version of Emacs.
7625 2012-02-25 Chong Yidong <cyd@gnu.org>
7627 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

7631 (x_clipboard_manager_save_all): Print an informative message
7632 before saving to clipboard manager.
7634 2012-02-24 Chong Yidong <cyd@gnu.org>
7636 * keyboard.c (process_special_events): Handle all X selection

7641 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
7642 call when setting menu-bar-lines and tool-bar-lines parameters.
7643 (unwind_create_frame_1): New helper function.
7645 * window.c (inhibit_window_configuration_change_hook): New var.
7646 (run_window_configuration_change_hook): Obey it.
7647 (syms_of_window): Initialize it.
7649 2012-02-22 Chong Yidong <cyd@gnu.org>
7651 * xterm.c (x_draw_image_relief): Add missing type check for

7663 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
7664 when computing $valmask.
7666 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
7667 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
7668 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
7669 It's useless in that case, and it can cause problems on hosts
7670 that allocate halves of EMACS_INT values separately.
7671 Reported by Dan Horák. Diagnosed by Andreas Schwab in
7672 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
7673 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
7674 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
7675 it avoids undefined behavior on hosts where shifting right by more
7676 than the word width has undefined behavior.
7678 2012-02-19 Chong Yidong <cyd@gnu.org>
7680 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
7681 (Funhandled_file_name_directory, Ffile_name_as_directory)

7700 2012-02-15 Chong Yidong <cyd@gnu.org>
7702 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
7703 marked as special. Also, starting docstrings with * is obsolete.
7705 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

7721 as that creates a dangerous corner case.
7723 * window.c (Fdelete_window_internal): Invalidate the mouse
7724 highlight (Bug#9904).
7726 2012-02-12 Glenn Morris <rgm@gnu.org>

7731 * nsselect.m (Fx_own_selection_internal)
7732 (Fx_disown_selection_internal, Fx_selection_exists_p)
7733 (Fx_selection_owner_p, Fx_get_selection_internal):
7734 Sync docs and argument specs with the xselect.c versions.

7756 2012-02-07 Chong Yidong <cyd@gnu.org>
7758 * buffer.c (Fbuffer_local_variables)
7759 (buffer_lisp_local_variables): Handle unbound vars correctly;
7760 don't let Qunbound leak into Lisp.
7762 2012-02-07 Glenn Morris <rgm@gnu.org>
7764 * image.c (Fimagemagick_types): Doc fix.
7766 * image.c (imagemagick-render-type): Change it from a lisp object

7772 * doc.c (store_function_docstring): Avoid applying docstring of
7773 alias to base function (Bug#2603).

7799 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
7801 Handle overflow when computing char display width (Bug#9496).
7802 * character.c (char_width): Return EMACS_INT, not int.
7803 (char_width, c_string_width): Check for overflow when
7804 computing the width; this is possible now that individual
7805 characters can have unbounded width. Problem introduced
7806 by merge from Emacs 23 on 2012-01-19.
7808 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

7837 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
7838 first 2 arguments are identical. This makes inserting large
7839 output from a subprocess an order of magnitude faster on
7840 MS-Windows, where all sbrk'ed memory is always contiguous.

7946 emacs: fix an auto-save permissions race condition (Bug#10400)
7947 * fileio.c (auto_saving_dir_umask): New static var.
7948 (Fmake_directory_internal): Use it.
7949 (do_auto_save_make_dir): Set it, instead of invoking chmod after
7950 creating the directory. The old code temporarily assigns
7951 too-generous permissions to the directory.
7952 (do_auto_save_eh): Clear it.
7953 (Fdo_auto_save): Catch all errors, not just file errors, so
7954 that the var is always cleared.

8011 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8012 property that ends at ZV, so that the bidi iteration could be

8460 is set, removing the need for VIRT_ADDRESS_VARIES.
8461 (PURE_P): Use a more-efficient implementation that needs just one

8476 (erase_phys_cursor, update_window_cursor, show_mouse_face)
8477 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8478 behave as if the cursor position were at the window margin.
8480 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8481 and the cursor position is out of bounds, behave as if the cursor
8482 position were at the window margin. (Bug#10075)
8484 2011-11-18 Chong Yidong <cyd@gnu.org>
8486 * window.c (Fwindow_combination_limit): Make first argument

8512 * dispnew.c (verify_row_hash): Call row_hash for computing the
8513 hash code of a row, instead of duplicating code from xdisp.c.
8515 * dispextern.h (row_hash): Add prototype.

8989 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
8991 * w32fns.c (w32_default_color_map): New function,
8992 extracted from Fw32_default_color_map.
8993 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
8995 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
8997 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
8999 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9001 * keyboard.c (test_undefined): New function (bug#9751).
9002 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9004 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9006 * sysdep.c (init_sys_modes): Fix the check for the controlling
9007 terminal (Bug#6649).
9009 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9011 * dispextern.h (struct bidi_it): New member next_en_type.
9013 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9014 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9015 current character, check also for next_en_type being WEAK_EN.
9016 (bidi_resolve_weak): Don't enter the expensive loop if the current
9017 position is before next_en_pos. Record the bidi type of the first
9018 non-ET, non-BN character we find, in addition to its position.
9019 (bidi_level_of_next_char): Invalidate next_en_type when
9020 next_en_pos is over-stepped.
9022 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9024 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9025 * editfns.c: Rewrite current-time-zone so that it invokes
9026 the equivalent of (format-time-string "%Z") to get the time zone name.
9027 This fixes a bug when the time zone name contains characters that
9028 need converting from the system time locale to Emacs internal format.
9029 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9030 that patch fixed format-time-string to do the conversion, but
9031 I forgot to fix current-time-zone.
9032 (format_time_string): New function, containing most of
9033 what Fformat_time_string used to contain.
9034 (Fformat_time_string): Rewrite in terms of format_time_string.
9035 This doesn't change this function's behavior.
9036 (current-time-zone): Rewrite to use format_time_string.
9037 This fixes the bug reported by Michael Schierl in
9038 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9039 Jason Rumney's 2007-06-07 change worked around this bug, but
9041 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9043 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9045 * xdisp.c (start_display): If the character at POS is displayed
9046 via a display vector, reset IT->current.dpvec_index to zero.
9047 (try_window_reusing_current_matrix): If a line ends in a display
9048 vector or the next line starts in a display vector, continue
9049 redrawing the window even though the character position of
9050 start_row was reached.
9053 2011-10-18 Chong Yidong <cyd@gnu.org>
9055 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9056 with nobreak-char-display too.
9058 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9060 Fix part 3 of bug#9771.
9061 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9062 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9063 non-neutral characters if the current character is a paragraph
9064 separator (a.k.a. Newline). This avoids running the same
9065 expensive loop twice, once when we consume the preceding newline
9066 and the other time when the line actually needs to be displayed.
9067 Avoid the loop when we see neutrals on the base embedding level
9068 following a character whose directionality is the same as the
9069 paragraph's. This avoids running the expensive loop when a line
9070 ends in a long sequence of neutrals, like control characters.
9071 Add assertion against STRONG_AL type. Slightly rearrange code
9072 that determines the type of a neutral given the first non-neutral
9074 (bidi_level_of_next_char): Set next_en_pos to zero when
9075 invalidating its info.
9077 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9079 * xdisp.c (push_display_prop): Determine whether to record string
9080 or buffer position by IT->string, not by IT->method. Allow
9081 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9082 (move_it_vertically_backward): Don't look for character position
9083 immediately after the newline when in a continuation line.
9086 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9088 * window.c (coordinates_in_window): Rewrite and delabelize
9089 vertical border check. (Bug#5357) (Bug#9618)
9091 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9093 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9094 errors in XSetWindowBorder (bug#9310).
9096 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9098 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9099 avoid crash when xmalloc overrun checking is enabled.
9101 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9103 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9104 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9105 cursor motion with <left> and <right> arrow keys.
9107 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9108 some callers set that themselves.
9110 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9112 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9113 display string and the previous row comes from the same string and
9114 is empty. (Bug#9739) (Bug#9738)
9116 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9118 * doc.c (get_doc_string): Encode file name (bug#9735).
9120 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9122 * bidi.c (bidi_level_of_next_char):
9123 * xdisp.c (get_visually_first_element): Remove old incorrect
9124 comments regarding the Unicode Line Separator character.
9126 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9128 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9130 * alloc.c (Fgc_status): Do not access beyond zombies array
9131 boundary if nzombies > MAX_ZOMBIES.
9132 * alloc.c (dump_zombies): Add missing format specifier.
9134 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9136 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9137 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9139 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9140 Some packages use them to denote characters with modifiers.
9142 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9144 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9145 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9146 matching a pp-number. Rename parameter var to var1.
9148 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9150 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9152 2011-10-08 Glenn Morris <rgm@gnu.org>
9154 * callint.c (Fcall_interactively): Give a more explicit error for the
9155 'c' case with a non-character input. (Bug#8479)
9157 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9159 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9161 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9162 lines that are hscrolled on the left.
9164 * dispnew.c (buffer_posn_from_coords): Account for a possible
9165 presence of header-line. (Bug#4426)
9167 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9169 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9170 Don't advertise functionality which we discourage or doesn't work.
9172 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9174 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9175 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9176 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9177 this makes Emacs dump core during garbage collection on rare
9178 occasions. sizeof is obviously inferior to offsetof here, so
9179 stick with offsetof.
9180 (GC_POINTER_ALIGNMENT): New macro.
9181 (mark_memory): Omit 3rd (offset) arg; caller changed.
9182 Don't assume EMACS_INT alignment is the same as pointer alignment.
9184 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9186 * keyboard.c (read_key_sequence_remapped): New var.
9187 (read_key_sequence): Compute remapping in the right buffer.
9188 (command_loop_1): Use read_key_sequence's remapping directly.
9190 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9192 * dired.c (file_name_completion): Don't expand file name.
9193 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9194 before checking file name handler.
9196 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9197 they've been requested explicitly (bug#9591).
9199 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9201 * keymap.c (Fsingle_key_description): Use make_specified_string
9202 instead of build_string to build string from push_key_description.
9205 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9207 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9208 This fixes a Y2038 bug on 64-bit hosts.
9209 * buffer.c (reset_buffer):
9210 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9211 (Fclear_buffer_auto_save_failure):
9212 Use 0, not -1, to represent an unset failure time, since time_t
9213 might not be signed.
9215 Remove dependency on glibc malloc internals.
9216 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9217 Move back here from lisp.h, but with their new implementations.
9218 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9219 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9220 * charset.c (charset_table_init): New static var.
9221 (syms_of_charset): Use it instead of xmalloc. This removes a
9222 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9223 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9224 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9225 Move back to alloc.c.
9226 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9227 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9229 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9231 * nsterm.m (windowDidResize): Call x_set_window_size only when
9232 ns_in_resize is true. Otherwise set pixelwidth/height and
9233 call change_frame_size (Bug#9628).
9235 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9237 Port --enable-checking=all to Fedora 14 x86-64.
9238 * charset.c (syms_of_charset): Also account for glibc malloc's
9239 internal overhead when calculating the initial malloc maximum.
9241 Port --enable-checking=all to Fedora 14 x86.
9242 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9244 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9245 (overrun_check_realloc, overrun_check_free):
9246 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9247 That way, xmalloc returns a properly-aligned pointer even if
9248 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9249 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9250 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9251 into account when calculating the initial malloc maximum.
9252 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9253 Move here from alloc.c, so that charset.c can use it too.
9254 Properly align; the old code wasn't right for common 32-bit hosts
9255 when configured with --enable-checking=all.
9256 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9257 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9259 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9261 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9264 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9266 * xdisp.c (compute_display_string_end): If there's no display
9267 string at CHARPOS, return -1.
9269 * bidi.c (bidi_fetch_char): When compute_display_string_end
9270 returns a negative value, treat the character as a normal
9271 character not covered by a display string. (Bug#9624)
9273 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9275 * lread.c (Fread_from_string): Fix typo in docstring.
9277 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9279 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9280 newline, reseat the iterator instead of bidi-iterating there one
9281 character at a time. (Bug#9610)
9282 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9283 TO_CHARPOS if the bidi iterator is at base embedding level.
9285 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9287 * lread.c (readevalloop): Use correct code for NBSP.
9288 (read1): Likewise. (Bug#9608)
9290 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9292 * dbusbind.c (Fdbus_register_signal): When service is not
9293 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9295 2011-09-25 Glenn Morris <rgm@gnu.org>
9297 * buffer.c (truncate-lines): Doc fix.
9299 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9301 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9302 (Fset_window_next_buffers): Doc fix.
9304 2011-09-24 Glenn Morris <rgm@gnu.org>
9306 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9308 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9310 Fix minor problems found by static checking.
9311 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9312 * indent.c (Fvertical_motion): Fix == vs = typo.
9314 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9316 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9317 Default value is now t. Doc fix.
9319 * indent.c (Fvertical_motion): Compute and apply the overshoot
9320 logic when moving up, not only when moving down. Fix the
9321 confusing name and values of the it_overshoot_expected variable;
9322 logic changes accordingly. (Bug#9254) (Bug#9549)
9324 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9325 CHARPOS is covered by a display string which includes newlines.
9326 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9327 is covered by a display string with embedded newlines.
9329 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9331 * dbusbind.c (Fdbus_register_signal): Add match rule to
9332 Vdbus_registered_objects_table. (Bug#9581)
9333 (Fdbus_register_method, Vdbus_registered_objects_table):
9336 2011-09-24 Jim Meyering <meyering@redhat.com>
9338 do not ignore write error for any output size
9339 The previous change was incomplete.
9340 While it makes emacs --batch detect the vast majority of stdout
9341 write failures, errors were still ignored whenever the output size is
9342 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9343 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9344 && echo FAIL: ignored write error
9345 FAIL: ignored write error
9346 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9347 && echo FAIL: ignored write error
9348 FAIL: ignored write error
9349 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9351 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9353 * emacs.c (Fkill_emacs): In noninteractive mode exit
9354 non-successfully if a write error occurred on stdout. (Bug#9574)
9356 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9358 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9361 * dispextern.h (struct it): Update the comment documenting what
9364 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9366 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9367 a display string, extend search for cursor position to end of row.
9368 (find_row_edges): If the row ends in a newline from a display
9369 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9370 Handle the case of a display string with multiple newlines.
9371 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9372 non-empty line. Fixes confusing cursor motion with arrow keys at
9373 the beginning of a line that starts with whitespace.
9375 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9377 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9380 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9382 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9385 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9387 * xdisp.c (display_line): Record maximum and minimum buffer
9388 positions even if no glyphs were produced (e.g., by a zero-width
9389 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9390 buffer positions that will be removed from the glyph row because
9392 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9393 column is beyond frame width: don't subtract 1 "pixel" when
9394 computing width of the stretch.
9395 (reseat_at_next_visible_line_start): Undo the change made on
9396 2011-09-17 that saved paragraph information and restored it after
9397 the call to `reseat'. (Bug#9545)
9399 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9401 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9402 and turn window cursor on if cleared (Bug#9415).
9404 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9406 * search.c (boyer_moore): Take unibyte characters from pattern
9407 literally. (Bug#9458)
9409 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9411 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9413 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9415 Fix minor problem found by static checking.
9416 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9417 initialized, to pacify gcc -Wuninitialized.
9419 * fileio.c: Report proper errno when syscall falls.
9420 (Finsert_file_contents): Save and restore errno,
9421 so that report_file_error outputs the correct diagnostic.
9422 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9424 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9426 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9428 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9430 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9431 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9433 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9435 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9436 about the current paragraph and restore it after the call to reseat.
9438 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9439 (bidi_find_paragraph_start): Search back for paragraph beginning
9440 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9441 (bidi_move_to_visually_next): Only trigger paragraph-related
9442 computations when the last character is a newline or at EOB, not
9443 just any NEUTRAL_B. (Bug#9470)
9445 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9446 truncated lines if point is covered by a display string. (Bug#9524)
9448 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9450 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9451 (cons_to_x_long): New function.
9452 (lisp_data_to_selection_data): Use it. Correct the test for
9453 short-versus-long data; it was negated. Break out of vector
9454 loop, for efficiency, when a long datum is discovered.
9456 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9458 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9460 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9462 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9463 GCC PR/17406) by declaring this function with external scope.
9465 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9467 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9468 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9470 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9472 * editfns.c (Fformat): Correctly handle text properties on "%%".
9474 2011-09-15 Eli Zaretskii <eliz@gnu.org>
9476 * xterm.c (x_draw_composite_glyph_string_foreground):
9477 * w32term.c (x_draw_composite_glyph_string_foreground):
9478 * term.c (encode_terminal_code):
9479 * composite.c (composition_update_it, get_composition_id):
9480 * xdisp.c (get_next_display_element)
9481 (fill_composite_glyph_string): Add comments about special meaning
9482 of TAB characters in a composition.
9484 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9486 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9487 This occurs when processing a multibyte format.
9488 Problem reported by Wolfgang Jenker.
9490 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9492 * xdisp.c (try_cursor_movement): Only check for exact match if
9493 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9495 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9497 Remove unused external symbols.
9498 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9499 * xdisp.c (calc_pixel_width_or_height): Now static.
9500 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9501 * indent.c (check_display_width):
9502 * w32term.c: Fix comment to match code.
9503 * xterm.c, xterm.h (x_catching_errors): Remove.
9505 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9507 * xselect.c: Use signed conversions more consistently (Bug#9498).
9508 (selection_data_to_lisp_data): Assume incoming selection data are
9509 signed integers, not unsigned. This is to be consistent with
9510 outgoing selection data, which was modified to use signed integers
9511 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9512 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9513 expects long, not unsigned long.
9515 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9517 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9518 computation of loop end. Reported by Johan Bockgård
9521 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9523 * frame.c (Fother_visible_frames_p): Function deleted.
9525 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9527 * indent.c (compute_motion): Process display vector front to back
9528 rather than the other way around. (Bug#2496)
9530 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9532 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9534 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9536 * minibuf.c (Fread_from_minibuffer): Doc fix.
9538 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9540 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9541 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9543 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9545 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9546 value for non-existent files.
9548 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9550 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9551 set its "size" to -1. This will set the modtime_size field of
9552 the corresponding buffer to -1, which is what
9553 verify-visited-file-modtime expects for files that do not exist.
9556 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9558 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9560 * lisp.h: ... from here. push_key_description is no longer
9561 defined in keyboard.c, so its declaration should not be in
9562 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9563 logically belongs with push_key_description.
9565 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9567 * buffer.h: Include <sys/types.h> instead of <time.h>.
9568 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9569 Problem reported by Herbert J. Skuhra.
9571 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9573 * xml.c (parse_region): Make the parsing work for
9574 non-comment-starting XML files again (bug#9144).
9576 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9578 * image.c (gif_load): Fix calculation of bottom and right corner.
9581 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9583 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9584 redisplay in small windows.
9586 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9588 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9590 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9592 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9593 Operate on live windows only.
9595 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
9597 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
9599 2011-09-07 Eli Zaretskii <eliz@gnu.org>
9601 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
9602 only under bidi iteration.
9604 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
9606 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9608 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9610 isnan: Fix porting problem to Solaris 10 with bundled gcc.
9611 Without this fix, the command to link temacs failed due to an
9612 undefined symbol __builtin_isnan. This is because
9613 /usr/include/iso/math_c99.h #defines isnan(x) to
9614 __builtin_isnan(x), but the bundled gcc, which identifies itself
9615 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
9617 * floatfns.c (isnan): #undef, and then #define to a clone of
9619 (Fisnan): Always define, since it's always available now.
9620 (syms_of_floatfns): Always define isnan at the Lisp level.
9622 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9624 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
9626 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9628 * fileio.c: Fix bugs with large file offsets (Bug#9428).
9629 The previous code assumed that file offsets (off_t values) fit in
9630 EMACS_INT variables, which is not true on typical 32-bit hosts.
9631 The code messed up by falsely reporting buffer overflow in cases
9632 such as (insert-file-contents "big" nil 1 2) into an empty buffer
9633 when "big" contains more than 2**29 bytes, even though this
9634 inserts just one byte and does not overflow the buffer.
9635 (Finsert_file_contents): Store file offsets as off_t
9636 values, not as EMACS_INT values. Check for overflow when
9637 converting between EMACS_INT and off_t. When checking for
9638 buffer overflow or for overlap, take the offsets into account.
9639 Don't use EMACS_INT for small values where int suffices.
9640 When checking for overlap, fix a typo: ZV was used where
9641 ZV_BYTE was intended.
9642 (Fwrite_region): Don't assume off_t fits into 'long'.
9643 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
9645 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
9647 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
9649 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9651 sprintf-related integer and memory overflow issues (Bug#9412).
9653 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
9654 (esprintf, exprintf, evxprintf): New functions.
9655 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
9656 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
9657 (modify_event_symbol): Do not assume that the length of
9658 name_alist_or_stem is safe to alloca and fits in int.
9659 (Fexecute_extended_command): Likewise for function name and binding.
9660 (Frecursion_depth): Wrap around reliably on integer overflow.
9661 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
9662 since some callers pass EMACS_INT values.
9663 (Fsingle_key_description): Don't crash if symbol name contains more
9664 than MAX_ALLOCA bytes.
9665 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
9666 (get_minibuffer): Arg is now EMACS_INT, not int.
9667 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
9668 (esprintf, exprintf, evxprintf): New decls.
9669 * window.h (command_loop_level, minibuf_level): Reflect API changes.
9671 * dbusbind.c (signature_cat): New function.
9672 (xd_signature, Fdbus_register_signal):
9673 Do not overrun buffer; instead, report string overflow.
9675 * dispnew.c (add_window_display_history): Don't overrun buffer.
9676 Truncate instead; this is OK since it's just a log.
9678 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
9679 even if the time zone offset is outlandishly large.
9680 Don't mishandle offset == INT_MIN.
9682 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
9683 when creating daemon; the previous buffer-overflow check was incorrect.
9685 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
9686 which has the guts of the old verror function.
9688 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
9689 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
9691 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
9692 (font_unparse_xlfd): Don't blindly alloca long strings.
9693 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
9694 fits in int, when using sprintf. Use single snprintf to count
9695 length of string rather than counting it via multiple sprintfs;
9696 that's simpler and more reliable.
9697 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
9698 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
9699 sprintf, in case result does not fit in int.
9701 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
9702 (fontset_from_font): Print it.
9704 * frame.c (tty_frame_count): Now printmax_t, not int.
9705 (make_terminal_frame, set_term_frame_name): Print it.
9706 (x_report_frame_params): In X, window IDs are unsigned long,
9707 not signed long, so print them as unsigned.
9708 (validate_x_resource_name): Check for implausibly long names,
9709 and don't assume name length fits in 'int'.
9710 (x_get_resource_string): Don't blindly alloca invocation name;
9711 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
9714 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
9715 (xg_check_special_colors, xg_set_geometry):
9716 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
9718 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
9719 Use esprintf, not sprintf, in case result does not fit in int.
9721 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9722 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
9723 it as a large positive number.
9724 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
9725 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9727 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
9728 in case result does not fit in int.
9730 * print.c (float_to_string): Detect width overflow more reliably.
9731 (print_object): Make sprintf buffer a bit bigger, to avoid potential
9732 buffer overrun. Don't assume list length fits in 'int'. Treat
9733 print length of 0 as 0, not as infinity; to be consistent with other
9734 uses of print length in this function. Don't overflow print length
9735 index. Don't assume hash table size fits in 'long', or that
9736 vectorlike size fits in 'unsigned long'.
9738 * process.c (make_process): Use printmax_t, not int, to format
9739 process-name gensyms.
9741 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
9743 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
9744 to avoid potential buffer overrun.
9746 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
9747 if X resource line is longer than 512 bytes.
9749 * xfns.c (x_window): Make sprintf buffer a bit bigger
9750 to avoid potential buffer overrun.
9752 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
9754 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
9756 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9758 Integer overflow fixes for scrolling, etc.
9759 Without these, Emacs silently mishandles large integers sometimes.
9760 For example, "C-u 4294967297 M-x recenter" was treated as if
9761 it were "C-u 1 M-x recenter" on a typical 64-bit host.
9763 * xdisp.c (try_window_id): Check Emacs fixnum range before
9764 converting to 'int'.
9766 * window.c (window_scroll_line_based, Frecenter):
9767 Check that an Emacs fixnum is in range before assigning it to 'int'.
9768 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
9769 values converted from Emacs fixnums.
9770 (Frecenter): Don't wrap around a line count if it is out of 'int'
9771 range; instead, treat it as an extreme value.
9772 (Fset_window_configuration, compare_window_configurations):
9773 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
9775 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
9776 that can exceed INT_MAX. Check that EMACS_INT value is in range
9777 before assigning it to the (possibly-narrower) index.
9778 (match_limit): Don't assume that a fixnum can fit in 'int'.
9780 * print.c (print_object): Use ptrdiff_t, not int, for index that can
9783 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
9784 (Fvertical_motion): Don't wrap around LINES values that don't fit
9785 in 'int'. Instead, treat them as extreme values. This is good
9786 enough for windows, which can't have more than INT_MAX lines anyway.
9788 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9790 * Require libxml/parser.h to avoid compilation warning.
9792 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
9794 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
9795 since this reportedly can destroy thread storage.
9797 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
9799 * syntax.c (find_defun_start): Update all cache variables if
9800 exiting early (Bug#9401).
9802 2011-08-30 Eli Zaretskii <eliz@gnu.org>
9804 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
9806 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
9807 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
9808 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
9810 * term.c (tty_append_glyph): New function.
9811 (produce_stretch_glyph): Static function and its prototype deleted.
9813 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
9816 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
9818 * image.c (parse_image_spec): Check for nonnegative, not for positive,
9819 when checking :margin (Bug#9390).
9820 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
9821 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
9822 so that the name doesn't mislead. All uses changed.
9824 2011-08-28 Johan Bockgård <bojohan@gnu.org>
9826 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
9829 2011-08-27 Eli Zaretskii <eliz@gnu.org>
9831 * xdisp.c (move_it_to): Don't bail out early when reaching
9832 position beyond to_charpos, if we are scanning backwards.
9833 (move_it_vertically_backward): When DY == 0, make sure we get to
9834 the first character in the line after the newline.
9836 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
9838 * ccl.c: Improve and simplify overflow checking (Bug#9196).
9839 (ccl_driver): Do not generate an out-of-range pointer.
9840 (Fccl_execute_on_string): Remove unnecessary check for
9841 integer overflow, noted by Stefan Monnier in
9842 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
9843 Remove a FIXME that didn't need fixing.
9844 Simplify the newly-introduced buffer reallocation code.
9846 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
9848 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
9850 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
9852 Integer and memory overflow issues (Bug#9196).
9854 * doc.c (get_doc_string): Rework so that
9855 get_doc_string_buffer_size is the actual buffer size, rather than
9856 being 1 less than the actual buffer size; this makes xpalloc more
9859 * image.c (x_allocate_bitmap_record, cache_image):
9860 * xselect.c (Fx_register_dnd_atom):
9861 Simplify previous changes by using xpalloc.
9863 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
9864 since either will do and ptrdiff_t is convenient with xpalloc.
9866 * charset.c (charset_table_size)
9867 (struct charset_sort_data.priority): Now ptrdiff_t.
9868 (charset_compare): Don't overflow if priorities differ greatly.
9869 (Fsort_charsets): Don't assume list length fits in int.
9870 Check for size-calculation overflow when allocating sort data.
9871 (syms_of_charset): Allocate an initial charset table that is
9872 just under 64 KiB, to avoid problems with glibc malloc and mmap.
9874 * cmds.c (internal_self_insert): Check for size-calculation overflow.
9876 * composite.h (struct composition.glyph_len): Now int, not unsigned.
9877 The actual value is always <= INT_MAX, and leaving it unsigned made
9878 overflow checking harder.
9880 * dispextern.h (struct glyph_matrix.rows_allocated)
9881 (struct face_cache.size): Now ptrdiff_t, for convenience in use
9882 with xpalloc. The values are still always <= INT_MAX.
9884 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
9886 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
9887 (SAFE_NALLOCA): New macro.
9889 * region-cache.c (struct boundary.pos, find_cache_boundary)
9890 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
9891 (set_cache_region, invalidate_region_cache)
9892 (revalidate_region_cache, know_region_cache, region_cache_forward)
9893 (region_cache_backward, pp_cache):
9894 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
9895 so that ptrdiff_t * can be passed to xpalloc.
9896 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
9897 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
9898 (pp_cache): Don't assume cache_len fits in int.
9899 * region-cache.h: Adjust extern decls to match.
9901 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
9902 EMACS_INT, since either will do, for xpalloc.
9904 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
9905 (xnmalloc, xnrealloc, xpalloc): New functions.
9907 * bidi.c (bidi_shelve_header_size): New constant.
9908 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
9909 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
9911 * bidi.c (bidi_cache_shrink):
9912 * buffer.c (overlays_at, overlays_in, record_overlay_string)
9914 Don't update size of array until after memory allocation succeeds,
9915 because xmalloc/xrealloc may not return.
9916 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
9917 now that we have proper integer overflow checking.
9918 (record_overlay_string, overlay_strings): Catch overflows when
9919 calculating size of overlay_str_buf.
9921 * callproc.c (Fcall_process): Check for size overflow when
9922 calculating size of args2.
9923 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
9924 Normally we prefer signed values, but sticking with ptrdiff_t would
9925 require adding more-complicated checks.
9927 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
9928 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
9929 Redo buffer-overflow calculations to avoid integer overflow.
9930 Add a FIXME comment where memory seems to be over-allocated.

9968 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
9970 * emacs.c (main): Do not reallocate argv, since there is a null at
9971 the end that can be overwritten, and this way there's no need to
9972 worry about size-calculation overflow.

10103 Use them to make the following changes clearer.
10104 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

10106 future maintainers not to raise the value too much later.
10107 (SELECTION_QUANTUM): Remove, replacing with ...
10108 (selection_quantum): ... new function, which avoids overflow.
10110 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10111 assumption that selection length fits in 'int'.

10128 Don't store size until memory allocation succeeds.
10129 (x_get_window_property): Plug memory leak on memory exhaustion.
10130 Don't double-block input; malloc is safe here. Don't assume 2**34
10131 - 4 fits in unsigned long. Add an xassert to check
10132 XGetWindowProperty overflow. Be more careful about overflow
10133 calculations, and distinguish size from memory overflow better.
10134 (receive_incremental_selection): When tracing, don't assume
10135 unsigned int is less than INT_MAX.
10136 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10140 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10141 result parameters unless successful. Rely on cons_to_unsigned
10142 to report problems with elements; the old code wasn't right anyway.
10143 (x_check_property_data): Check for int overflow; we cannot use
10144 a wider type due to X limits.

10177 * lisp.h (hash_lookup, hash_put):
10178 * minibuf.c (Ftest_completion):
10179 Use ptrdiff_t for hash table indexes, not int (which is too
10180 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10181 32-bit --with-wide-int hosts).
10183 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10184 Add a FIXME comment about memory leaks.

10213 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10214 (x_send_scroll_bar_event): Likewise. Check that the size does not
10215 exceed limits imposed by XClientMessageEvent, as well as the usual
10216 ptrdiff_t and size_t limits.
10218 * keyboard.c: Overflow, signedness and related fixes.
10219 (make_lispy_movement): Use same integer type in forward decl
10220 that is used in the definition.
10221 (read_key_sequence, keyremap_step):
10222 Change bufsize argument back to int, undoing my 2011-03-30 change.
10223 We prefer signed types, and int is wide enough here.
10224 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10225 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10226 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10227 length, not size_t. Use ptrdiff_t for index, not int.
10228 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10229 possibility of integer overflow.

10257 Prefer int to unsigned where either will do.
10258 (tiff_handler): New function, combining the cores of the
10259 old tiff_error_handler and tiff_warning_handler.

10261 stack buffer overflows. It uses only the features of vsnprintf
10262 that are common to both POSIX and native Microsoft.
10263 (tiff_error_handler, tiff_warning_handler): Use it.
10264 (tiff_load, gif_load, imagemagick_load_image):
10265 Don't assume :index value fits in 'int'.
10266 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
10267 (imagemagick_load_image): Check that crop parameters fit into
10268 the integer types that MagickCropImage accepts. Don't assume
10269 Vimagemagick_render_type has a nonnegative value. Don't assume
10270 size_t fits in 'long'.
10271 (gs_load): Use printmax_t to print the widest integers possible.

10285 (handle_single_display_spec): If the display spec is of the form
10286 `(space ...)', and specifies display in the text area, return 2
10288 (try_cursor_movement): Check for the need to scroll more
10289 accurately, and prefer exact match for point under bidi.
10290 Don't advance `row' beyond the last row of the window.

10308 buffers, return left-to-right.
10309 (set_cursor_from_row): Consider candidate row a win if its glyph
10310 represents a newline and point is on that newline. Fixes cursor
10311 positioning on the newline at EOL of R2L text within L2R
10312 paragraph, and vice versa.
10313 (try_cursor_movement): Check continued rows, in addition to
10314 continuation rows. Fixes unwarranted scroll when point enters a
10315 continued line of R2L text within an L2R paragraph, or vice versa.
10316 (cursor_row_p): Consider the case of point being equal to
10317 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10318 from the end of a short line to the beginning of a continued line
10319 of R2L text within L2R paragraph.
10320 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

10343 * xdisp.c (redisplay_window): When computing centering_position,
10344 account for the height of the header line. (Bug#8874)
10346 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10347 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10348 candidate is selected by the mouse, and that candidate has a
10349 composed character under the mouse.
10351 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10352 coordinates reported by pos-visible-in-window-p for a composed
10353 character in column zero.

10362 consider it a hit if to_charpos is anywhere in the range of the
10363 composed buffer positions.
10365 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10367 * image.c (gif_load): Don't assume that each subimage has the same
10368 dimensions as the base image. Handle disposal method that is
10369 "undefined" by the gif spec (Bug#9335).
10371 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10373 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10379 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10380 from an Org mode buffer to a Speedbar frame.
10382 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10383 a composition, take its buffer position from IT->cmp_it.charpos.
10384 Fixes cursor positioning at the beginning of a line that begins
10385 with a composed character.
10387 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10389 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10390 character bidirectional type, use STRONG_L instead. Fixes crashes
10391 in a buffer produced by `describe-categories'.
10393 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10394 members before the level stack, so they would be saved and
10395 restored when copying iterator state. Fixes incorrect reordering
10396 around TABs covered by display properties.
10398 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10400 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10405 (internal_condition_case_2, internal_condition_case_n):
10406 Remove unnecessary aborts (Bug#9081).
10408 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10410 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10411 has no `load' handler, try opening the file locally. (Bug#9311)
10413 2011-08-16 Ken Brown <kbrown@cornell.edu>
10415 * gmalloc.c: Expand comment.
10417 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10431 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10433 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10434 in the static heap.
10435 [CYGWIN] (special_realloc): New function.
10436 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
10437 requests to realloc storage in the static heap.

10452 * chartab.c: Improve commentary for the uniprop_table API.
10454 * bidi.c (bidi_paragraph_init): Support zero value of
10455 bidi_ignore_explicit_marks_for_paragraph_level.
10456 (bidi_initialize): Use uniprop_table instead of including
10457 biditype.h and bidimirror.h.
10459 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
10460 coordinates of the iterator when restoring from ppos_it.
10463 2011-08-14 Kenichi Handa <handa@m17n.org>

10468 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10470 * xdisp.c (move_it_in_display_line_to): Don't invoke
10471 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10472 ppos_it. Fixes vertical cursor motion when line beginning is
10473 covered by an image. (Bug#9296)
10475 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10477 * nsterm.h (ns_run_ascript): Declare.
10478 (NSAPP_DATA2_RUNASSCRIPT): Define.
10480 * nsfns.m (as_script, as_result, as_status): New static variables.
10481 (ns_run_ascript): New function.
10482 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10483 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10484 the event loop. Get status from as_status (Bug#7276).
10486 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10487 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10488 the event loop (Bug#7276).
10490 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10492 * gnutls.c (QCgnutls_bootprop_priority)
10493 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10494 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10495 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10496 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10497 (QCgnutls_bootprop_verify_hostname_error)
10498 (QCgnutls_bootprop_callbacks_verify): Rename from
10499 Qgnutls_bootprop_..., all uses changed.

10513 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10514 (Fnetwork_interface_list): Allocate in increments of bytes instead
10515 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10516 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10518 (struct ifflag_def): notrailers is smart on OSX.
10519 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10520 Get hardware address with getifaddrs if available.
10522 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10524 * xdisp.c (iterate_out_of_display_property): xassert that
10525 IT->position is set to within IT->object's boundaries. Break from
10526 the loop as soon as EOB is reached; avoids infloops in redisplay
10527 when IT->position is set up wrongly due to some bug.
10528 Set IT->current to match the bidi iterator unconditionally.
10529 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10530 entry. Force push_it to save on the stack the current
10531 buffer/string position, to be restored by pop_it. Fix flags in
10532 the iterator structure wrt the object coming from a display
10533 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10534 properties. (Bug#9284)
10536 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10538 * fontset.c (fontset_get_font_group): Add proper type checks.

10551 no-display-properties-and-no-overlays under bidi display.
10552 Set disp_pos in the bidi iterator to avoid searches for display
10553 properties and overlays.
10555 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10557 * editfns.c (Fset_time_zone_rule): Document relationship with the

10563 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10565 * composite.c (autocmp_chars): Don't reset point. That is done by
10566 restore_point_unwind (Bug#5984).
10568 2011-08-07 Juri Linkov <juri@jurta.org>
10570 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10571 to show the arg `TIME' instead of `TIMEVAL'.
10573 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10575 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10576 display property strides EOL and includes a newline, as in
10577 longlines-mode. (Bug#9254)
10578 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10579 word-wrap under bidirectional display. (Bug#9224)
10581 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10582 is non-zero, even if the data buffer is NULL. Fixes a crash in
10583 vertical-motion with longlines-mode. (Bug#9254)
10585 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10587 * bidi.c <bidi_cache_total_alloc>: Now static.
10588 (bidi_initialize): Initialize bidi_cache_total_alloc.
10590 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10593 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10594 amount allocated this far in `bidi_cache_total_alloc'.
10595 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10596 non-zero, only free the data buffer without restoring the cache
10597 contents. All callers changed.
10599 * dispextern.h (bidi_unshelve_cache): Update prototype.
10601 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10602 (move_it_in_display_line, move_it_to)
10603 (move_it_vertically_backward, move_it_by_lines): Replace the call
10604 to xfree to an equivalent call to bidi_unshelve_cache.
10605 (move_it_in_display_line_to): Fix logic of returning
10606 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
10608 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10610 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
10611 came from a string character with a `cursor' property. (Bug#9229)
10613 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10615 * Makefile.in (LIB_PTHREAD): New variable.
10616 (LIBES): Add LIB_PTHREAD (Bug#9216).
10618 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
10619 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
10621 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
10623 * regex.c (re_iswctype): Remove some redundant boolean conversions.
10625 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10627 * xterm.c (x_find_topmost_parent): New function.
10628 (x_set_frame_alpha): Find topmost parent window with
10629 x_find_topmost_parent and set the property there also (bug#9181).
10630 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
10632 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
10634 * callproc.c (Fcall_process): Avoid vfork clobbering
10635 the local vars buffer, coding_systems, current_dir.
10637 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
10639 * keymap.c (Fmake_composed_keymap): Move to subr.el.
10641 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
10643 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
10644 so that it is not optimized away.
10646 * xdisp.c (compute_display_string_pos): Remove unused local.
10648 2011-08-02 Eli Zaretskii <eliz@gnu.org>
10650 Fix slow cursor motion and scrolling in large buffers with
10651 selective display, like Org Mode buffers. (Bug#9218)
10653 * dispextern.h (struct bidi_it): New member disp_prop_p.
10655 * xdisp.c: Remove one-slot cache of display string positions.
10656 (compute_display_string_pos): Accept an additional argument
10657 DISP_PROP_P; callers changed. Scan at most 5K characters forward
10658 for a display string or property. If found, set DISP_PROP_P
10661 * bidi.c (bidi_fetch_char): Accept an additional argument
10662 DISP_PROP_P, and pass it to compute_display_string_pos.
10663 Only handle text covered by a display string if DISP_PROP_P is returned
10664 non-zero. All callers of bidi_fetch_char changed.
10666 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
10668 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
10670 2010-12-03 Don March <don@ohspite.net>
10672 * keymap.c (Fdefine_key): Fix non-prefix key error message when
10673 last character M-[char] is translated to ESC [char] (bug#7541).
10675 2011-08-02 Kenichi Handa <handa@m17n.org>
10677 * lisp.h (uniprop_table): Extern it.
10679 * chartab.c (uniprop_table): Make it non-static.
10681 2011-08-01 Eli Zaretskii <eliz@gnu.org>
10683 * xdisp.c (forward_to_next_line_start): Accept additional argument
10684 BIDI_IT_PREV, and store into it the state of the bidi iterator had
10686 (reseat_at_next_visible_line_start): Use the bidi iterator state
10687 returned by forward_to_next_line_start to restore the state of
10688 it->bidi_it after backing up to previous newline. (Bug#9212)
10690 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
10692 * regex.c (re_comp): Protoize.
10693 (re_exec): Fix return type.
10694 (regexec): Fix type of `ret'. (Bug#9203)
10696 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10698 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
10699 This is needed if max-image-size is a floating-point number.
10701 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10703 * print.c (print_object): Print empty symbol as ##.
10705 * lread.c (read1): Read ## as empty symbol.
10707 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10709 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
10710 setting frame foreground color (Bug#9175).
10711 (x_set_background_color): Likewise.
10713 * nsmenu.m (-setText): Size tooltip dimensions precisely to
10714 contents (Bug#9176).
10715 (EmacsTooltip -init): Remove bezels and add shadows to
10718 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
10719 or scroll bar (Bug#8470).
10721 * nsfont.m (nsfont_open): Remove assignment to voffset and
10722 unnecessary vars hshink, expand, hd, full_height, min_height.
10723 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
10725 * nsterm.h (nsfont_info): Remove voffset field.
10727 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10729 Implement strike-through and overline on NextStep (Bug#8863).
10731 * nsfont.m (nsfont_open): Use underline position provided by font,
10732 instead of hard-coded value of 2.
10733 (nsfont_draw): Call ns_draw_text_decoration instead.
10735 * nsterm.h: Add declaration for ns_draw_text_decoration.
10737 * nsterm.m (ns_draw_text_decoration): New function for drawing
10738 underline, overline, and strike-through.

10741 accommodate underlining, etc.
10743 2011-07-28 Eli Zaretskii <eliz@gnu.org>
10745 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
10748 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10750 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
10751 Without this fix, if a signal arrives just after memory fills up,
10752 'malloc' might be invoked reentrantly.
10754 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
10755 In other words, assume that every image size is allowed, on non-X
10756 hosts. This assumption is probably wrong, but it lets Emacs compile.
10758 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10760 * regex.c (re_iswctype): Convert return values to boolean.
10762 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
10764 * xdisp.c (compute_display_string_pos): Don't use cached display
10765 string position if the buffer had its restriction changed.
10768 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10770 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10772 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10774 Integer signedness and overflow and related fixes. (Bug#9079)
10776 * bidi.c: Integer size and overflow fixes.
10777 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
10778 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
10779 (bidi_cache_find_level_change, bidi_cache_ensure_space)
10780 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
10781 (bidi_find_other_level_edge):
10782 Use ptrdiff_t instead of EMACS_INT where either will do.
10783 This works better on 32-bit hosts configured --with-wide-int.
10784 (bidi_cache_ensure_space): Check for size-calculation overflow.
10785 Use % rather than repeated addition, for better worst-case speed.
10786 Don't set bidi_cache_size until after xrealloc returns, because it
10788 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
10789 (bidi_cache_ensure_space): Also check that the bidi cache size
10790 does not exceed that of the largest Lisp string or buffer. See Eli
10791 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
10793 * alloc.c (__malloc_size_t): Remove.
10794 All uses replaced by size_t. See Andreas Schwab's note
10795 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
10797 * image.c: Improve checking for integer overflow.
10798 (check_image_size): Assume that f is nonnull, since
10799 it is always nonnull in practice. This is one less thing to
10800 worry about when checking for integer overflow later.
10801 (x_check_image_size): New function, which checks for integer
10802 overflow issues inside X.
10803 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
10804 This removes the need for a memory_full check.
10805 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
10806 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
10807 (xbm_read_bitmap_data): Change locals back to 'int', since
10808 their values must fit in 'int'.
10809 (xpm_load_image, png_load, tiff_load):
10810 Invoke x_create_x_image_and_pixmap earlier,
10811 to avoid much needless work if the image is too large.
10812 (tiff_load): Treat overly large images as if
10813 x_create_x_image_and_pixmap failed, not as malloc failures.
10814 (gs_load): Use x_check_image_size.
10816 * gtkutil.c: Omit integer casts.
10817 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
10818 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
10820 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
10822 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
10823 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
10824 would wrongly return t on a 64-bit host.
10826 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
10827 The plain *_OVERFLOW macros run afoul of GCC bug 49705
10828 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
10829 and therefore cause GCC to emit a bogus diagnostic in some cases.
10831 * image.c: Integer signedness and overflow and related fixes.
10832 This is not an exhaustive set of fixes, but it's time to
10833 record what I've got.
10834 (lookup_pixel_color, check_image_size): Remove redundant decls.
10835 (check_image_size): Don't assume that arbitrary EMACS_INT values
10836 fit in 'int', or that arbitrary 'double' values fit in 'int'.
10837 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
10838 (tiff_load, imagemagick_load_image):
10839 Check for overflow in size calculations.
10840 (x_create_x_image_and_pixmap): Remove unnecessary test for
10841 xmalloc returning NULL; that can't happen.
10842 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
10843 (xpm_color_bucket): Use better integer hashing function.
10844 (xpm_cache_color): Don't possibly over-allocate memory.
10845 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
10846 (gif_memory_source):
10847 Use ptrdiff_t, not int or size_t, to record sizes.
10848 (png_load): Don't assume values greater than 2**31 fit in 'int'.
10849 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
10850 either works, as we prefer signed integers.
10851 (tiff_read_from_memory, tiff_write_from_memory):
10852 Return tsize_t, not size_t, since that's what the TIFF API wants.
10853 (tiff_read_from_memory): Don't fail simply because the read would
10854 go past EOF; instead, return a short read.
10855 (tiff_load): Omit no-longer-needed casts.
10856 (Fimagemagick_types): Don't assume size fits into 'int'.
10858 Improve hashing quality when configured --with-wide-int.
10859 * fns.c (hash_string): New function, taken from sxhash_string.
10860 Do not discard information about ASCII character case; this
10861 discarding is no longer needed.
10862 (sxhash-string): Use it. Change sig to match it. Caller changed.
10863 * lisp.h: Declare it.
10864 * lread.c (hash_string): Remove, since we now use fns.c's version.
10865 The fns.c version returns a wider integer if --with-wide-int is
10866 specified, so this should help the quality of the hashing a bit.
10868 * emacs.c: Integer overflow minor fix.
10869 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
10870 Define only if GNU_LINUX.
10871 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
10873 * dispnew.c: Integer signedness and overflow fixes.
10874 Remove unnecessary forward decls, that were a maintenance hassle.
10875 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
10877 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
10878 (scrolling_window): Use ptrdiff_t, not int, for byte count.
10879 (prepare_desired_row, line_draw_cost):
10880 Use int, not unsigned, where either works.
10881 (save_current_matrix, restore_current_matrix):
10882 Use ptrdiff_t, not size_t, where either works.
10883 (init_display): Check for overflow more accurately, and without
10884 relying on undefined behavior.
10886 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
10887 Remove, replacing with the new symbols in lisp.h. All uses changed.
10888 * fileio.c (make_temp_name):
10889 * filelock.c (lock_file_1, lock_file):
10890 * xdisp.c (message_dolog):
10891 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
10892 Use pMd etc. instead.
10893 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
10894 replacing the pWIDE etc. symbols removed from editfns.c.
10896 * keyboard.h (num_input_events): Now uintmax_t.
10897 This is (very slightly) less likely to mess up due to wraparound.
10900 * buffer.c: Integer signedness fixes.
10901 (alloc_buffer_text, enlarge_buffer_text):
10902 Use ptrdiff_t rather than size_t when either will do, as we prefer
10905 * alloc.c: Integer signedness and overflow fixes.
10906 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
10907 (__malloc_size_t): Default to size_t, not to int.
10908 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
10909 (Fgarbage_collect, mark_object_loop_halt, mark_object):
10910 Prefer ptrdiff_t to size_t when either would do, as we prefer
10912 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
10913 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
10914 Now const. Initialize with values that are in range even if char
10916 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
10917 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
10918 These functions do the right thing with sizes > 2**32.
10919 (check_depth): Now ptrdiff_t, not int.
10920 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
10921 Adjust to new way of storing sizes. Check for size overflow bugs
10923 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
10924 slightly wrong anyway, as it missed one instance of
10925 XMALLOC_OVERRUN_CHECK_OVERHEAD.
10926 (refill_memory_reserve): Omit needless cast to size_t.
10927 (mark_object_loop_halt): Mark as externally visible.
10929 * xselect.c: Integer signedness and overflow fixes.
10930 (Fx_register_dnd_atom, x_handle_dnd_message):
10931 Use ptrdiff_t, not size_t, since we prefer signed.
10932 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
10933 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
10934 x_dnd_atoms_size and x_dnd_atoms_length.
10936 * doprnt.c: Prefer signed to unsigned when either works.
10938 * doprnt.c (doprnt):
10940 * xdisp.c (vmessage):
10941 Use ptrdiff_t, not size_t, when using or implementing doprnt,
10942 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
10943 prefer signed arithmetic to avoid comparison confusion.
10944 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
10945 but is a bit tricky.
10947 Assume freestanding C89 headers, string.h, stdlib.h.
10948 * data.c, doprnt.c, floatfns.c, print.c:
10949 Include float.h unconditionally.
10950 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10951 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10952 * regex.c: Likewise for stddef.h, string.h.
10953 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10954 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10955 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10956 (STDC_HEADERS): Remove obsolete defines.
10957 * sysdep.c: Include limits.h unconditionally.
10959 Assume support for memcmp, memcpy, memmove, memset.
10960 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10961 * regex.c (memcmp, memcpy):
10962 Remove; we assume C89 now.
10964 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
10965 (__malloc_safe_bcopy): Remove; no longer needed.
10967 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
10968 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
10969 well either way, and we prefer signed to unsigned.
10971 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
10973 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
10974 closes the connection while we're reading (bug#9182).
10976 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10978 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
10979 are specified (Bug#9168).
10981 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
10983 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
10984 Found by GCC static checking and --with-wide-int on a 32-bit host.
10986 2011-07-25 Eli Zaretskii <eliz@gnu.org>
10988 * xdisp.c (compute_display_string_pos): Fix logic of caching
10989 previous display string position. Initialize cached_prev_pos to
10990 -1. Fixes slow-down at the beginning of a buffer.
10992 2011-07-24 Eli Zaretskii <eliz@gnu.org>
10994 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
10995 for attrs[LFACE_FONTSET_INDEX].
10997 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
10999 * xml.c (parse_region): Remove unused local
11000 that was recently introduced.
11002 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11004 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11005 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11007 * xdisp.c (move_it_in_display_line_to): Record the best matching
11008 position for TO_CHARPOS while scanning the line, and restore it on
11009 exit if none of the characters scanned was an exact match.
11010 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11011 when exact match is impossible due to invisible text, and the
11012 lines are truncated.
11014 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11016 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11019 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11021 Fix a significant slow-down of cursor motion with C-n, C-p,
11022 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11023 auto-repeat under bidi redisplay in fontified buffers.
11024 * xdisp.c (compute_stop_pos_backwards): New function.
11025 (next_element_from_buffer): Call compute_stop_pos_backwards to
11026 find a suitable prev_stop when we find ourselves before
11028 (reseat): Don't look for prev_stop, as that could mean a very long
11030 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11031 <cached_disp_overlay_modiff>: Cache for last found display string
11033 (compute_display_string_pos): Return the cached position if asked
11034 about the same buffer in the same area of character positions, and
11035 the buffer wasn't changed since the time the display string
11036 position was cached.
11038 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11040 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11041 is an integer, which is important for empty lines. (Bug#9149)
11043 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11045 * frame.c (Fmodify_frame_parameters): In tty case, update the
11046 default face if necessary (Bug#4238).
11048 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11050 * editfns.c (Fstring_to_char): No need to explain what a character
11051 is in the docstring (Bug#6576).
11053 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11055 * xml.c (parse_region): Make sure we always return a tree.
11057 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11059 * xml.c (parse_region): If a document contains only comments,
11062 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11064 * xml.c (make_dom): Return comments, too.
11066 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11069 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11070 and the surrounding thread.
11071 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11072 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11073 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11075 * s/openbsd.h (BROKEN_SIGIO): Define.
11076 * unexelf.c (unexec) [__OpenBSD__]:
11077 Don't update the .mdebug section of the Alpha COFF symbol table.
11079 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11081 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11084 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11086 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11087 This fixes some race conditions on the permissions of any newly
11090 * alloc.c (valid_pointer_p): Use pipe, not open.
11091 This fixes some permissions issues when debugging.
11093 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11094 If fchown fails to set both uid and gid, try to set just gid,
11095 as that is sometimes allowed. Adjust the file's mode to eliminate
11096 setuid or setgid bits that are inappropriate if fchown fails.
11098 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11100 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11101 to compare Lisp_Objects.
11102 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11103 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11104 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11106 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11108 * lread.c (read_integer): Unread even EOF character.
11109 (read1): Likewise. Properly record start position of symbol.
11111 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11112 symbol character follows.
11114 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11116 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11117 This works around a problem with the previous change to Fcopy_file.
11118 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11119 and without this change, GCC might complain about discarding
11120 fchown's return value.
11122 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11124 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11126 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11128 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11130 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11132 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11133 it's used from the C level.
11135 * process.c: Use the same condition for POLL_FOR_INPUT in both
11136 keyboard.c and process.c (bug#1858).
11138 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11140 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11141 (Fgnutls_boot): Use it.
11143 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11145 * doc.c (Fsubstitute_command_keys): Revert last change.
11147 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11149 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11150 quotes the next character, and doesn't affect other longer
11151 sequences (bug#8935).
11153 * lread.c (syms_of_lread): Clarify that is isn't only
11154 `eval-buffer' and `eval-defun' that's affected by
11155 `lexical-binding' (bug#8460).
11157 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11159 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11160 bidi redisplay when a line includes both an image and is truncated.
11162 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11164 Fix minor problems found by static checking.
11165 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11166 (elsz): Now a signed constant, not a size_t var. We prefer signed
11167 types to unsigned, to avoid integer comparison confusion. Without
11168 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11169 "cannot optimize loop, the loop counter may overflow", a symptom
11171 * indent.c (Fvertical_motion): Mark locals as initialized.
11172 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11174 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11176 * search.c (Fre_search_backward): Mention `case-fold-search' in
11177 all the re_search_* functions (bug#8138).
11179 * keyboard.c (Fopen_dribble_file): Document when the file is
11182 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11184 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11187 Support bidi reordering of display and overlay strings.
11188 * xdisp.c (compute_display_string_pos)
11189 (compute_display_string_end): Accept additional argument STRING.
11190 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11191 (reseat_to_string): Initialize bidi_it->string.s and
11192 bidi_it->string.schars.
11193 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11194 NULL (avoids a crash in bidi_paragraph_init).
11195 Initialize itb.string.lstring.
11196 (init_iterator): Call bidi_init_it only of a valid
11197 buffer position was specified. Initialize paragraph_embedding to
11199 (reseat_to_string): Initialize the bidi iterator.
11200 (display_string): If we need to ignore text properties of
11201 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11202 original value of -1 will not work with bidi.)
11203 (compute_display_string_pos): First arg is now struct
11204 `text_pos *'; all callers changed. Support display properties on
11206 (compute_display_string_end): Support display properties on Lisp
11208 (init_iterator, reseat_1, reseat_to_string): Initialize the
11209 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11210 when iterating on a string not from display properties).
11211 (compute_display_string_pos, compute_display_string_end):
11212 Fix calculation of the object to scan. Fixes an error when using
11214 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11215 base_level_stop; instead, set base_level_stop to BEGV.
11216 Fixes crashes in vertical-motion.
11217 (next_element_from_buffer): Improve commentary for when
11218 the iterator is before prev_stop.
11219 (init_iterator): Initialize bidi_p from the default value of
11220 bidi-display-reordering, not from buffer-local value. Use the
11221 buffer-local value only if initializing for buffer iteration.
11222 (handle_invisible_prop): Support invisible properties on strings
11223 that are being bidi-reordered.
11224 (set_iterator_to_next): Support bidi reordering of C strings and
11226 (next_element_from_string): Support bidi reordering of Lisp
11228 (handle_stop_backwards): Support Lisp strings as well.
11229 (display_string): Support display of R2L glyph rows.
11230 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11231 (init_iterator): Don't initialize it->bidi_p for strings
11233 (reseat_to_string): Initialize it->bidi_p for strings here.
11234 (next_element_from_string, next_element_from_c_string)
11235 (next_element_from_buffer): Add xassert's for correspondence
11236 between IT's object being iterated and it->bidi_it.string
11238 (face_before_or_after_it_pos): Support bidi iteration.
11239 (next_element_from_c_string): Handle the case of the first string
11240 character that is not the first one in the visual order.
11241 (get_visually_first_element): New function, refactored from common
11242 parts of next_element_from_buffer, next_element_from_string, and
11243 next_element_from_c_string.
11244 (tool_bar_lines_needed, redisplay_tool_bar)
11245 (display_menu_bar): Force left-to-right direction. Add a FIXME
11246 comment for making that be controlled by a user option.
11247 (push_it, pop_it): Save and restore the state of the
11248 bidi iterator. Save and restore the bidi_p flag.
11249 (pop_it): Iterate out of display property for string iteration as
11251 (iterate_out_of_display_property): Support iteration over strings.
11252 (handle_single_display_spec): Set up it->bidi_it for iteration
11253 over a display string, and call bidi_init_it.
11254 (handle_single_display_spec, next_overlay_string)
11255 (get_overlay_strings_1, push_display_prop): Set up the bidi
11256 iterator for displaying display or overlay strings.
11257 (forward_to_next_line_start): Don't use the shortcut if
11259 (back_to_previous_visible_line_start): If handle_display_prop
11260 pushed the iterator stack, restore the internal state of the bidi
11261 iterator by calling bidi_pop_it same number of times.
11262 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11263 and we are bidi-iterating, don't decrement the iterator position;
11264 instead, set the first_elt flag in the bidi iterator, to produce
11266 (reseat_1): Remove redundant setting of string_from_display_prop_p.
11267 (push_display_prop): xassert that we are iterating a buffer.
11268 (push_it, pop_it): Save and restore paragraph_embedding member.
11269 (handle_single_display_spec, next_overlay_string)
11270 (get_overlay_strings_1, reseat_1, reseat_to_string)

11735 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
11737 Random fixes. E.g., (random) never returned negative values.
11738 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
11739 subseconds part to the entropy, as that's a bit more random.
11740 Prefer signed to unsigned, since the signedness doesn't matter and
11741 in general we prefer signed. When given a limit, use a
11742 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
11743 latter isn't right if USE_2_TAGS_FOR_INTS.
11744 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
11745 not 0..VALMASK. Don't discard "excess" bits that random () returns.
11747 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11749 * textprop.c (text_property_stickiness):
11750 Obey Vtext_property_default_nonsticky.

11758 This is more efficient than Ffile_directory_p and avoids a minor race.
11760 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
11762 * buffer.c (Foverlay_put): Say what the return value is
11765 * fileio.c (barf_or_query_if_file_exists): Check first if the file
11766 is a directory before asking whether to use the file name
11768 (barf_or_query_if_file_exists): Make the "File is a directory"
11769 error be more correct.
11771 * fns.c (Frequire): Remove the mention of the .gz files, since
11772 that's installation-specific, but keep the mention of
11773 `get-load-suffixes'.
11775 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
11777 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

11785 Qgnutls_bootprop_verify_error (which is no longer used).
11787 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
11788 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
11789 Also (re)move comments that are misplaced or no longer relevant.
11791 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11793 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

11890 * eval.c (struct backtrace): Simplify and port the data structure.
11891 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
11892 signed bit field, as this assumption is not portable and it makes
11893 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
11894 "char debug_on_exit : 1" as this is not portable either; instead,
11895 use the portable "unsigned int debug_on_exit : 1". Remove unused
11896 member evalargs. Remove obsolete comments about cc bombing out.
11898 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
11900 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

11968 (emacs_fixed_get_preferred_height): Use min_width/height from
11969 frames size_hint to set minimum and natural (Bug#8919).
11970 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
11971 and use min_width/height from frames size_hint to set
11972 min_width/height (Bug#8919).

12064 * print.c (printchar, strout): Check for string overflow.
12065 (PRINTPREPARE, printchar, strout):
12066 Don't set size unless allocation succeeds.
12068 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12069 for sizes. Check for string overflow more accurately.

12073 * keyboard.h (struct keyboard.kbd_macro_bufsize):
12074 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

12083 (read_integer): Radix is now EMACS_INT, not int,
12084 to improve quality of diagnostics for out-of-range radices.
12085 Calculate buffer size correctly for out-of-range radices.
12086 (read1): Check for integer overflow in radices, and in
12087 read-circle numbers.
12088 (read_escape): Avoid int overflow.
12089 (Fload, openp, read_buffer_size, read1)
12090 (substitute_object_recurse, read_vector, read_list, map_obarray):
12091 Use ptrdiff_t, not int, for sizes.

12111 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12113 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12114 The following patches are for when GLYPH_DEBUG && !XASSERT.
12115 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12116 * dispnew.c (flush_stdout):
12117 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12118 Mark as externally visible.
12119 * dispnew.c (check_window_matrix_pointers): Now static.
12120 * dispnew.c (window_to_frame_vpos):
12121 * xfns.c (unwind_create_frame):
12122 * xterm.c (x_check_font): Remove unused local.
12123 * scroll.c (CHECK_BOUNDS):
12124 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12125 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.

12128 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12130 (debug_method_add): Use va_list and vsprintf rather than relying
12131 on undefined behavior with wrong number of arguments.
12132 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12133 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12134 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12135 since we're not interested in debugging glyphs with old libraries.
12136 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12137 GCC 4.6.0's static checking.
12139 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12141 Integer overflow and signedness fixes (Bug#8873).

12157 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12158 (.bitmaps_last, struct x_output.icon_bitmap):
12159 Use ptrdiff_t, not int, for bitmap indexes.
12160 (x_allocate_bitmap_record): Check for size overflow.
12161 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12163 Use ptrdiff_t, not int, for overlay counts.
12164 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12165 * editfns.c (overlays_around, get_pos_property):
12166 * textprop.c (get_char_property_and_overlay):
12167 * xdisp.c (next_overlay_change, note_mouse_highlight):
12168 * xfaces.c (face_at_buffer_position):
12169 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12170 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12171 (Fnext_overlay_change, Fprevious_overlay_change)
12172 (mouse_face_overlay_overlaps, Foverlays_in):
12173 Use ptrdiff_t, not int, for sizes.
12174 (overlays_at, overlays_in): Check for size-calculation overflow.
12176 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12178 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12179 (x_session_initialize): Do not assume string length fits in int.
12181 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12182 This is unlikely, but can occur if DPI is outlandish.
12184 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12185 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12187 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12188 * xrdb.c (magic_file_p, search_magic_path):
12189 Omit last arg SUFFIX; it was always 0. All callers changed.
12190 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12192 * xfont.c (xfont_match): Avoid need for strlen.
12194 * xfns.c: Don't assume strlen fits in int.
12195 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12197 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12198 not unsigned long, as we prefer signed integers. All callers changed.
12199 Detect integer overflow in repeat count.
12200 (message_dolog): Don't assume print length fits in 39 bytes.
12201 (display_mode_element): Don't assume strlen fits in int.
12203 * termcap.c: Don't assume sizes fit in int and never overflow.
12204 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12205 (gobble_line): Check for size-calculation overflow.
12207 * minibuf.c (Fread_buffer):
12208 * lread.c (intern, intern_c_string):
12209 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12210 Don't assume string length fits in int.
12212 * keyboard.c (parse_tool_bar_item):
12213 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12215 * font.c: Don't assume string length fits in int.
12216 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12217 Use ptrdiff_t, not int.
12218 (font_intern_prop): Don't assume string length fits in int.
12219 Don't assume integer property fits in fixnum.
12220 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12222 * filelock.c: Fix some buffer overrun and integer overflow issues.
12223 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12224 Reformulate so as not to need the command string.
12225 Invoke gzip -cd rather than gunzip, as it's more portable.
12226 (lock_info_type, lock_file_1, lock_file):
12227 Don't assume pid_t and time_t fit in unsigned long.
12228 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12229 (current_lock_owner): Prefer signed type for sizes.
12230 Use memcpy, not strncpy, where memcpy is what is really wanted.
12231 Don't assume (via atoi) that time_t and pid_t fit in int.
12232 Check for time_t and/or pid_t out of range, e.g., via a network share.
12233 Don't alloca where an auto var works fine.
12235 * fileio.c: Fix some integer overflow issues.
12236 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12237 Don't assume string length fits in int.
12238 (directory_file_name): Don't assume string length fits in long.
12239 (make_temp_name): Don't assume pid fits in int, or that its print
12240 length is less than 20.
12242 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12244 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12246 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12248 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12249 We prefer signed integers, even for size calculations.
12251 * emacs.c: Don't assume string length fits in 'int'.
12252 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12253 (main): Don't invoke strlen when not needed.
12255 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

12258 * callproc.c (getenv_internal_1, getenv_internal)
12259 (Fgetenv_internal):
12260 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12262 * lread.c (invalid_syntax): Omit length argument.
12263 All uses changed. This doesn't fix a bug, but it simplifies the
12264 code away from its former Hollerith-constant appearance, and it's
12265 one less 'int' to worry about when looking at integer-overflow issues.
12266 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12268 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12269 This didn't break anything, but it didn't help either.
12270 It's confusing to put a bogus integer in a place where the actual
12271 value does not matter.
12272 (LIST_END_P): Remove unused macro and its bogus comment.
12273 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12275 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12276 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12278 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12279 We prefer signed types, and the value cannot exceed the EMACS_INT
12280 range anyway (because otherwise the length would not be representable).
12281 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12282 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12283 This avoids a GCC warning when WIDE_EMACS_INT.
12285 * indent.c (sane_tab_width): New function.
12286 (current_column, scan_for_column, Findent_to, position_indentation)
12287 (compute_motion): Use it. This is just for clarity.
12288 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12290 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12292 * lisp.h (lint_assume): New macro.
12293 * composite.c (composition_gstring_put_cache):
12294 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12296 * editfns.c, insdel.c:
12297 Omit unnecessary forward decls, to simplify future changes.
12299 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12301 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12303 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12304 Use much-faster test for byte-length change.
12305 Don't assume string byte-length fits in 'int'.
12306 Check that character arg fits in 'int'.
12307 (mapcar1): Declare byte as byte, for clarity.
12309 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12311 * fns.c (concat): Catch string overflow earlier.
12312 Do not rely on integer wraparound.
12314 * dispextern.h (struct it.overlay_strings_charpos)
12315 (struct it.selective): Now EMACS_INT, not int.
12316 * xdisp.c (forward_to_next_line_start)
12317 (back_to_previous_visible_line_start)
12318 (reseat_at_next_visible_line_start, next_element_from_buffer):
12319 Don't arbitrarily truncate the value of 'selective' to int.
12321 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12323 * composite.c: Don't truncate sizes to 'int'.
12324 (composition_gstring_p, composition_reseat_it)
12325 (composition_adjust_point): Use EMACS_INT, not int.
12326 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12327 not EMACS_UINT, for indexes.
12329 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12331 * buffer.c: Include <verify.h>.
12332 (struct sortvec.priority, struct sortstr.priority):
12333 Now EMACS_INT, not int.
12334 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12335 (struct sortstr.size, record_overlay_string)
12336 (struct sortstrlist.size, struct sortlist.used):
12337 Don't truncate size to int.
12338 (record_overlay_string): Check for size-calculation overflow.
12339 (init_buffer_once): Check at compile-time, not run-time.
12341 2011-06-22 Jim Meyering <meyering@redhat.com>
12343 Don't leak an XBM-image-sized buffer
12344 * image.c (xbm_load): Free the image buffer after using it.
12346 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12349 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12350 that Sun C diagnosed.
12351 * fns.c (secure_hash): Fix pointer signedness issue.
12352 * intervals.c (static_offset_intervals): New function.
12353 (offset_intervals): Use it.
12355 2011-06-21 Leo Liu <sdl.web@gmail.com>
12358 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12361 * fns.c (secure_hash): Rename from crypto_hash_function and change
12362 the first arg to accept symbols.
12363 (Fsecure_hash): New primitive.
12364 (syms_of_fns): New symbols.
12366 2011-06-20 Deniz Dogan <deniz@dogan.se>
12368 * process.c (Fset_process_buffer): Clarify return value in
12371 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12373 * dispnew.c (add_window_display_history): Use BVAR.
12375 * xdisp.c (debug_method_add): Use BVAR.
12376 (check_window_end, dump_glyph_matrix, dump_glyph)
12377 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12379 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12382 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12383 check till after the cache is created in init_frame_faces.
12385 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12387 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12389 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12391 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12392 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12393 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12395 Improve buffer-overflow checking (Bug#8873).
12396 * fileio.c (Finsert_file_contents):
12397 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12398 Remove the old (too-loose) buffer overflow checks.
12399 They weren't needed, since make_gap checks for buffer overflow.
12400 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12401 The old code merely checked for Emacs fixnum overflow, and relied
12402 on undefined (wraparound) behavior. The new code avoids undefined
12403 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12405 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12406 Tune. Don't use wider integers than needed. Don't use alloca.
12407 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12409 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12411 * insdel.c, lisp.h (buffer_overflow): New function.
12412 (insert_from_buffer_1, replace_range, replace_range_2):
12413 * insdel.c (make_gap_larger):
12414 * editfns.c (Finsert_char):
12415 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12417 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12419 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12421 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12423 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12424 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12426 * fileio.c: Don't assume EMACS_INT fits in off_t.
12427 (emacs_lseek): New static function.
12428 (Finsert_file_contents, Fwrite_region): Use it.
12429 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12431 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12433 * fns.c: Don't overflow int when computing a list length.
12434 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12435 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12436 truncation on 64-bit hosts. Check for QUIT every
12437 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12438 faster and is responsive enough.
12439 (Flength): Report an error instead of overflowing an integer.
12440 (Fsafe_length): Return a float if the value is not representable
12441 as a fixnum. This shouldn't happen except in contrived situations.
12442 (Fnthcdr, Fsort): Don't assume list length fits in int.
12443 (Fcopy_sequence): Don't assume vector length fits in int.
12445 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12446 (header_size, word_size): New constants.
12447 (allocate_vectorlike): Don't check size overflow here.
12448 (allocate_vector): Check it here instead, since this is the only
12449 caller of allocate_vectorlike that could cause overflow.
12450 Check that the new vector's length is representable as a fixnum.
12452 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12453 The previous code was bogus. For example, next_almost_prime (32)
12454 returned 39, which is undesirable as it is a multiple of 3; and
12455 next_almost_prime (24) returned 25, which is a multiple of 5 so
12456 why was the code bothering to check for multiples of 7?
12458 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12460 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12462 Variadic C functions now count arguments with ptrdiff_t.
12463 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12464 Back then I didn't know that the Emacs coding style prefers signed int.
12465 Also, in the meantime I found a few more instances where arguments
12466 were being counted with int, which may truncate counts on 64-bit
12467 machines, or EMACS_INT, which may be unnecessarily wide.
12468 * lisp.h (struct Lisp_Subr.function.aMANY)
12469 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12470 Arg counts are now ptrdiff_t, not size_t.
12471 All variadic functions and their callers changed accordingly.
12472 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12473 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12474 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12475 * callint.c (Fcall_interactively): Check arg count for overflow,
12476 to avoid potential buffer overrun. Use signed char, not 'int',
12477 for 'varies' array, so that we needn't bother to check its size
12478 calculation for overflow.
12479 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12480 * eval.c (apply_lambda):
12481 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12482 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12483 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12485 * callint.c (Fcall_interactively): Don't use index var as event count.
12487 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12488 * mem-limits.h (SIZE): Remove; no longer used.
12490 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12492 Remove unnecessary casts.
12493 * xterm.c (x_term_init):
12494 * xfns.c (x_set_border_pixel):
12495 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12496 These aren't needed now that we assume ANSI C.
12498 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12499 It's more likely to cause problems (due to unsigned overflow)
12502 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12504 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12506 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12508 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12510 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12512 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12514 GLYPH_CODE_FACE returns EMACS_INT, not int.
12515 * dispextern.h (merge_faces):
12516 * xfaces.c (merge_faces):
12517 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12518 Don't assume EMACS_INT fits in int.
12520 * character.h (CHAR_VALID_P): Remove unused parameter.
12521 * fontset.c, lisp.h, xdisp.c: All uses changed.
12523 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12525 * fns.c (concat): Minor tuning based on overflow analysis.
12526 This doesn't fix any bugs. Use int to hold character, instead
12527 of constantly refetching from Emacs object. Use XFASTINT, not
12528 XINT, for value known to be a character. Don't bother comparing
12529 a single byte to 0400, as it's always less.
12531 * floatfns.c (Fexpt):
12532 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12534 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12537 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12539 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12540 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12541 incorrectly succeed when S was a string, because 4294967386 was
12542 truncated before it was used.
12544 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12545 Otherwise, an out-of-range integer could cause undefined behavior
12548 * composite.c: Use int, not EMACS_INT, for characters.
12549 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12550 EMACS_INT, for values that are known to be in character range.
12551 This doesn't fix any bugs but is the usual style inside Emacs and
12552 may generate better code on 32-bit machines.
12554 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12555 This is for reasons similar to the recent CHAR_STRING fix.
12556 * charset.c (Fencode_char): Check that character arg is actually
12557 a character. Pass an int to ENCODE_CHAR.
12558 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12559 wider than 'int', as a compile-time check to prevent future regressions
12562 * character.c (char_string): Remove unnecessary casts.
12564 Make sure a 64-bit char is never passed to CHAR_STRING.
12565 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12566 by silently ignoring the top 32 bits, allowing some values
12567 that were far too large to be valid characters.
12568 * character.h: Include <verify.h>.
12569 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12570 arguments are no wider than unsigned, as a compile-time check
12571 to prevent future regressions in this area.
12573 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12574 (Fsubst_char_in_region):
12576 * xdisp.c (decode_mode_spec_coding):
12577 Adjust to CHAR_STRING's new requirement.
12578 * editfns.c (Finsert_char, Fsubst_char_in_region):
12579 * fns.c (concat): Check that character args are actually
12580 characters. Without this test, these functions did the wrong
12581 thing with wildly out-of-range values on 64-bit hosts.
12583 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12584 These casts should not be needed on 32-bit hosts, either.
12585 * keyboard.c (read_char):
12586 * lread.c (Fload): Remove casts to unsigned.

12646 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
12647 when a (possibly-narrower) signed value would do just as well.
12648 We prefer using signed arithmetic, to avoid comparison confusion.
12650 * alloc.c: Catch some string size overflows that we were missing.
12651 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
12652 for convenience in STRING_BYTES_MAX.
12653 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
12654 The definition here is exact; the one in lisp.h was approximate.
12655 (allocate_string_data): Check for string overflow. This catches
12656 some instances we weren't catching before. Also, it catches
12657 size_t overflow on (unusual) hosts where SIZE_MAX <= min
12658 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
12659 and ptrdiff_t and EMACS_INT are both 64 bits.
12661 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
12662 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

13240 instead of using explicit *_CHAR codes.
13241 (bidi_resolve_explicit, bidi_resolve_weak):

13250 (bidi_level_of_next_char): Don't try to lookup the cache for the
13251 next/previous character if nothing is cached there yet, or if we
13252 were just reseat()'ed to a new position.
13254 * xdisp.c (set_cursor_from_row): Set start and stop points
13255 according to the row's direction when priming the loop that looks
13256 for the glyph on which to display cursor.

13258 (display_prop_intangible_p): Reimplement to call
13259 handle_display_spec instead of single_display_spec_intangible_p.
13260 Accept 3 additional arguments needed by handle_display_spec.
13261 This fixes incorrect cursor motion across display property with complex
13262 values: lists, `(when COND...)' forms, etc.

13270 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13271 value of a `display' property is a "replacing spec".
13272 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13273 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13274 the display property, but just return a value indicating whether
13275 the display property will replace the characters it covers.
13276 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13277 frame_window_p members of struct bidi_it.

13303 * gnutls.c: Use Emacs's memory allocators.
13304 Without this change, the gnutls library would invoke malloc etc.
13305 directly, which causes problems on non-SYNC_INPUT hosts, and which
13306 runs afoul of improving memory_full behavior. (Bug#8761)
13307 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13308 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13309 xfree instead of the default malloc, realloc, free.
13310 (Fgnutls_boot): No need to check for memory allocation failure,
13311 since xmalloc does that for us.

13334 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13335 * alloc.c (allocate_vectorlike):
13336 Check for overflow in vector size calculations.
13337 * ccl.c (ccl_driver):
13338 Check for overflow when converting EMACS_INT to int.

13340 need to be updated by these changes.
13341 * fns.c (make_hash_table, maybe_resize_hash_table):
13342 Check for integer overflow with large hash tables.
13343 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13344 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13345 (SXHASH_REDUCE): New macro.
13346 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13347 Use it instead of discarding useful hash info with large hash values.
13348 (sxhash_float): New function.
13349 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13350 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13351 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13352 Rewrite to use FIXNUM_BITS, as this simplifies things.
13353 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13354 Adjust signatures to match updated version of code.
13355 (consing_since_gc): Now EMACS_INT, since a single hash table can
13356 use more than INT_MAX bytes.

13405 Make it possible to run ./temacs.
13407 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13408 syms_of_callproc does the same thing. Remove test for

13457 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13459 * xterm.h: Update prototype.
13461 2011-05-28 William Xu <william.xwl@gmail.com>
13463 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13464 exiting (Bug#8239).
13466 2011-05-28 Jim Meyering <meyering@redhat.com>
13468 Avoid a sign-extension bug in crypto_hash_function.
13469 * fns.c (to_uchar): Define.
13470 (crypto_hash_function): Use it to convert some newly-signed
13471 variables to unsigned, to avoid sign-extension bugs. For example,
13472 without this change, (md5 "truc") would evaluate to
13473 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13474 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13475 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13477 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13479 Integer overflow fixes.
13481 * dbusbind.c: Serial number integer overflow fixes.
13482 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13483 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13484 to hold a serial number that is too large for a fixnum.
13485 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13486 Check for serial numbers out of range. Decode any serial number
13487 that was so large that it became a float. (Bug#8722)
13489 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13490 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13491 Use XFASTINT rather than XUINT when numbers are nonnegative.
13492 (xd_append_arg, Fdbus_method_return_internal):
13493 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13494 arguments, check that Lisp number is nonnegative, rather than
13495 silently wrapping negative numbers around. (Bug#8722)
13496 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13499 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13501 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13503 ccl: Add integer overflow checks.
13504 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13505 (IN_INT_RANGE): New macros.
13506 (ccl_driver): Use them to check for integer overflow when
13507 decoding a CCL program. Many of the new checks are whether XINT (x)
13508 fits in int; it doesn't always, on 64-bit hosts. The new version
13509 doesn't catch all possible integer overflows, but it's an
13510 improvement. (Bug#8719)
13512 * alloc.c (make_event_array): Use XINT, not XUINT.
13513 There's no need for unsigned here.
13515 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13516 This follows up to the 2011-05-06 change that substituted uintptr_t
13517 for EMACS_INT. This case wasn't caught back then.
13519 Rework Fformat to avoid integer overflow issues.
13520 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13521 now (part of C89). Include <verify.h>.
13522 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13523 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13524 (Fformat): Avoid the prepass trying to compute sizes; it was only
13525 approximate and thus did not catch overflow reliably. Instead, walk
13526 through the format just once, formatting and computing sizes as we go,
13527 checking for integer overflow at every step, and allocating a larger
13528 buffer as needed. Keep track separately whether the format is
13529 multibyte. Keep only the most-recently calculated precision, rather
13530 than them all. Record whether each argument has been converted to
13531 string. Use EMACS_INT, not int, for byte and char and arg counts.
13532 Support field widths and precisions larger than INT_MAX. Avoid
13533 sprintf's undefined behavior with conversion specifications such as %#d
13534 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13535 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13536 formatting out-of-range floating point numbers with int
13537 formats. (Bug#8668)
13539 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13541 * data.c: Avoid integer truncation in expressions involving floats.
13542 * data.c: Include <intprops.h>.
13543 (arith_driver): When there's an integer overflow in an expression
13544 involving floating point, convert the integers to floating point
13545 so that the resulting value does not suffer from catastrophic
13546 integer truncation. For example, on a 64-bit host (* 4
13547 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13548 Do not rely on undefined behavior after integer overflow.
13550 merge count_size_as_multibyte, parse_str_to_multibyte
13551 * character.c, character.h (count_size_as_multibyte):
13552 Rename from parse_str_to_multibyte; all uses changed.
13553 Check for integer overflow.
13554 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13555 since it's now a duplicate of the other. This is more of
13556 a character than a buffer op, so better that it's in character.c.
13557 * fns.c, print.c: Adjust to above changes.
13559 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13561 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13563 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13565 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13566 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13567 (x_clipboard_manager_save): Now static.
13568 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13570 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13571 (crypto_hash_function): Now static.
13572 Fix pointer signedness problems. Avoid unnecessary initializations.
13574 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13576 * termhooks.h (Vselection_alist): Make it terminal-local.
13578 * terminal.c (create_terminal): Initialize it.
13580 * xselect.c: Support for clipboard managers.
13581 (Vselection_alist): Move to termhooks.h as terminal-local var.
13582 (LOCAL_SELECTION): New macro.
13583 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13584 (symbol_to_x_atom): Remove gratuitous arg.
13585 (x_handle_selection_request, lisp_data_to_selection_data)
13586 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13587 (x_own_selection, x_get_local_selection, x_convert_selection):
13588 New arg, specifying work frame. Use terminal-local Vselection_alist.
13589 (some_frame_on_display): Delete unused function.
13590 (Fx_own_selection_internal, Fx_get_selection_internal)
13591 (Fx_disown_selection_internal, Fx_selection_owner_p)
13592 (Fx_selection_exists_p): New optional frame arg.
13593 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13594 (x_handle_selection_clear): Don't treat other terminals with the
13595 same keyboard specially. Use the terminal-local Vselection_alist.
13596 (x_clear_frame_selections): Use Frun_hook_with_args.
13598 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13600 * xterm.h: Add support for those atoms.
13602 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13604 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13605 (converted_selections, conversion_fail_tag): New global variables.
13606 (x_selection_request_lisp_error): Free the above.
13607 (x_get_local_selection): Remove unnecessary code.
13608 (x_reply_selection_request): Args changed; handle arbitrary array
13609 of converted selections stored in converted_selections.
13610 Separate the XChangeProperty and SelectionNotify steps.
13611 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
13612 (x_convert_selection): New function.
13613 (x_handle_selection_event): Simplify.
13614 (x_get_foreign_selection): Don't ignore incoming requests while
13615 waiting for an answer; this will fail when we implement
13616 SAVE_TARGETS, and seems unnecessary anyway.
13617 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
13618 (Vx_sent_selection_functions): Doc fix.
13620 2011-05-26 Leo Liu <sdl.web@gmail.com>
13622 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
13624 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13626 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
13628 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
13629 for fringe update if it has periodic bitmap.
13630 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
13631 and fringe_bitmap_periodic_p.
13633 * fringe.c (get_fringe_bitmap_data): New function.
13634 (draw_fringe_bitmap_1, update_window_fringes): Use it.
13635 (update_window_fringes): Record periodicity of fringe bitmap in glyph
13636 row. Mark glyph row for fringe update if periodicity changed.
13638 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
13639 for fringe update unless it has periodic bitmap.
13641 2011-05-25 Kenichi Handa <handa@m17n.org>
13643 * xdisp.c (get_next_display_element): Set correct it->face_id for
13644 a static composition.
13646 2011-05-24 Leo Liu <sdl.web@gmail.com>
13649 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
13651 * fns.c (crypto_hash_function, Fsha1): New function.
13652 (Fmd5): Use crypto_hash_function.
13653 (syms_of_fns): Add Ssha1.
13655 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13657 * gnutls.c: Remove unused macros.
13658 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
13659 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
13660 Remove macros that are defined and never used.
13661 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
13663 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13665 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
13666 (Fx_get_selection_internal): Minor cleanup.
13667 (Fx_own_selection_internal): Rename arguments for consistency with
13670 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13672 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
13674 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13676 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
13678 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13680 * dispnew.c (scrolling_window): Don't exclude the case that the
13681 last enabled row in the desired matrix touches the bottom boundary.
13683 2011-05-21 Glenn Morris <rgm@gnu.org>
13685 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
13686 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
13687 and add some more files.
13689 2011-05-20 Eli Zaretskii <eliz@gnu.org>
13691 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
13692 report_file_error introduced by the change from 2011-05-07.
13694 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
13696 * systime.h (Time): Define only if emacs is defined.
13697 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
13698 where the include path doesn't have X11/X.h by default. See
13699 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
13701 2011-05-20 Kenichi Handa <handa@m17n.org>
13703 * composite.c (find_automatic_composition): Fix previous change.
13705 2011-05-20 Glenn Morris <rgm@gnu.org>
13707 * lisp.mk: New file, split from Makefile.in.
13708 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
13709 (shortlisp): Remove.
13710 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
13712 2011-05-19 Glenn Morris <rgm@gnu.org>
13714 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
13715 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
13716 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
13717 (lisp): Set the order to that of loadup.el.
13718 (shortlisp): Make it a copy of $lisp.
13719 (SOME_MACHINE_LISP): Remove.
13720 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
13721 Use just $shortlisp, not $SOME_MACHINE_LISP too.
13723 2011-05-18 Kenichi Handa <handa@m17n.org>
13725 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
13726 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
13727 (find_automatic_composition): Mostly rewrite for efficiency.
13729 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
13731 * makefile.w32-in: Update dependencies.
13733 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
13735 * menu.c: Include limits.h (fixes the MS-Windows build broken by
13736 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
13738 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
13740 Fix some integer overflow issues, such as string length overflow.
13742 * insdel.c (count_size_as_multibyte): Check for string overflow.
13744 * character.c (lisp_string_width): Check for string overflow.
13745 Use EMACS_INT, not int, for string indexes and lengths; in
13746 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
13747 the resulting string length overflows an EMACS_INT; instead,
13748 report a string overflow if no precision given. When checking for
13749 precision exhaustion, use a check that cannot possibly have
13750 integer overflow. (Bug#8675)
13751 * character.h (lisp_string_width): Adjust to new signature.
13753 * alloc.c (string_overflow): New function.
13754 (Fmake_string): Use it. This doesn't change behavior, but saves
13755 a few bytes and will simplify future changes.
13756 * character.c (string_escape_byte8): Likewise.
13757 * lisp.h (string_overflow): New decl.
13759 Fixups, following up to the user-interface timestamp change.
13760 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
13761 for UI timestamps, instead of unsigned long.
13762 * msdos.c (mouse_get_pos): Likewise.
13763 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
13764 * w32gui.h (Time): Define by including "systime.h" rather than by
13765 declaring it ourselves. (Bug#8664)
13767 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
13768 * image.c (clear_image_cache): Likewise.
13770 * term.c (term_mouse_position): Don't assume time_t wraparound.
13772 Be more systematic about user-interface timestamps.
13773 Before, the code sometimes used 'Time', sometimes 'unsigned long',
13774 and sometimes 'EMACS_UINT', to represent these timestamps.
13775 This change causes it to use 'Time' uniformly, as that's what X uses.
13776 This makes the code easier to follow, and makes it easier to catch
13777 integer overflow bugs such as Bug#8664.
13778 * frame.c (Fmouse_position, Fmouse_pixel_position):
13779 Use Time, not unsigned long, for user-interface timestamps.
13780 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
13781 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
13782 * keyboard.h (last_event_timestamp): Likewise.
13783 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
13784 * menu.h (xmenu_show): Likewise.
13785 * term.c (term_mouse_position): Likewise.
13786 * termhooks.h (struct input_event.timestamp): Likewise.
13787 (struct terminal.mouse_position_hook): Likewise.
13788 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
13789 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
13790 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
13791 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
13792 what it was before.
13793 * menu.h, termhooks.h: Include "systime.h", for Time.
13795 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
13796 Don't assume that the difference between two unsigned long values
13797 can fit into an integer. At this point, we know button_down_time
13798 <= event->timestamp, so the difference must be nonnegative, so
13799 there's no need to cast the result if double-click-time is
13800 nonnegative, as it should be; check that it's nonnegative, just in
13801 case. This bug is triggered when events are more than 2**31 ms
13802 apart (about 25 days). (Bug#8664)
13804 * xselect.c (last_event_timestamp): Remove duplicate decl.
13805 (x_own_selection): Remove needless cast to unsigned long.
13807 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
13808 that always fit in int. Use a sentinel instead of a counter, to
13809 avoid a temp and to allay GCC's concerns about possible int overflow.
13810 * frame.h (struct frame): Use int for menu_bar_items_used
13811 instead of EMACS_INT, since it always fits in int.
13813 * menu.c (grow_menu_items): Check for int overflow.
13815 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
13817 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
13818 Before, the code was not consistent. These values cannot exceed
13819 2**31 - 1 so there's no need to make them unsigned.
13820 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
13821 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
13822 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
13824 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
13826 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
13827 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
13828 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
13829 presumably because the widths might not match.
13831 * window.c (size_window): Avoid needless test at loop start.
13833 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
13835 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
13837 2011-05-12 Drew Adams <drew.adams@oracle.com>
13839 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
13841 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13843 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
13844 `width' to `bar_area_x' and `bar_area_width', respectively.
13845 (x_scroll_run): Take account of fringe background extension.
13847 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
13848 Rename local vars `left' and `width' to `bar_area_x' and
13849 `bar_area_width', respectively.
13850 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
13851 background extension.
13853 2011-05-10 Jim Meyering <meyering@redhat.com>
13855 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
13857 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
13859 * image.c (Finit_image_library): Return t for built-in image types,
13860 like pbm and xbm. (Bug#8640)
13862 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
13864 * w32menu.c (set_frame_menubar): Fix submenu allocation.
13866 2011-05-07 Eli Zaretskii <eliz@gnu.org>
13868 * w32console.c (Fset_screen_color): Doc fix.
13869 (Fget_screen_color): New function.
13870 (syms_of_ntterm): Defsubr it.
13872 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
13873 unlink the temporary file if Fcall_process didn't create it in the
13875 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
13876 child process will be redirected to a file specified with `:file'.
13877 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
13878 cue to call_process_cleanup not to close that handle.
13880 2011-05-07 Ben Key <bkey76@gmail.com>
13882 * makefile.w32-in: The bootstrap-temacs rule now makes use of
13883 one of two shell specific rules, either bootstrap-temacs-CMD or
13884 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
13885 to the previous implementation of the bootstrap-temacs rule.
13886 The bootstrap-temacs-CMD rule is similar to the previous
13887 implementation of the bootstrap-temacs rule except that it
13888 makes use of the ESC_CFLAGS variable instead of the CFLAGS
13891 These changes, along with some changes to nt/configure.bat,
13892 nt/gmake.defs, and nt/nmake.defs, are required to extend my
13893 earlier fix to add support for --cflags and --ldflags options
13894 that include quotes so that it works whether make uses cmd or
13897 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
13899 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
13900 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
13902 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
13903 a string. Handle both cases.
13904 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
13905 (Fdbus_register_method): Use Qinvalid_function.
13907 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
13909 * makefile.w32-in: Update dependencies.
13910 (LISP_H): Add inttypes.h and stdin.h.
13911 (PROCESS_H): Add unistd.h.
13913 2011-05-06 Eli Zaretskii <eliz@gnu.org>
13915 * lread.c: Include limits.h (fixes the MS-Windows build broken by
13916 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
13918 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
13920 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
13922 * term.c (vfatal): Remove stray call to va_end.
13923 It's not needed and the C Standard doesn't allow it here anyway.
13925 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
13926 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
13928 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
13931 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
13933 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13935 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
13937 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
13939 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
13941 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
13942 * charset.c (Fdefine_charset_internal): Don't initialize
13943 charset.code_space[15]. The value was garbage, on hosts with
13944 32-bit int (Bug#8600).
13946 * lread.c (read_integer): Be more consistent with string-to-number.
13947 Use string_to_number to do the actual conversion; this avoids
13948 rounding errors and fixes some other screwups. Without this fix,
13949 for example, #x1fffffffffffffff was misread as -2305843009213693952.
13950 (digit_to_number): Move earlier, for benefit of read_integer.
13951 Return -1 if the digit is out of range for the base, -2 if it is
13952 not a digit in any supported base. (Bug#8602)
13954 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13956 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13957 to match comment at start of function. This also removes a
13958 GCC warning about overflow in a 32+64-bit port.
13960 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
13962 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
13963 Reported by Stefan Monnier in
13964 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
13965 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13966 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
13968 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
13969 (EMACS_UINTPTR): Likewise, with uintptr_t.
13971 * lisp.h: Prefer 64-bit EMACS_INT if available.
13972 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
13973 on 32-bit hosts that have 64-bit int, so that they can access
13975 However, temporarily disable this change unless the temporary
13976 symbol WIDE_EMACS_INT is defined.
13978 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
13980 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
13981 This removes an assumption that EMACS_INT and long are the same
13982 width as pointers. The assumption is true for Emacs porting targets
13983 now, but we want to make other targets possible.
13984 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
13985 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
13986 In the rest of the code, change types of integers that hold casted
13987 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
13988 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
13989 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
13990 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
13991 No need to cast type when ORing.
13992 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
13993 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
13994 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
13995 assume EMACS_INT is the same width as char *.
13996 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
13997 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
13998 Remove no-longer-needed casts.
13999 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14000 (xg_tool_bar_help_callback, xg_make_tool_item):
14001 Use EMACS_INTPTR to hold an integer
14002 that will be cast to void *; this can avoid a GCC warning
14003 if EMACS_INT is not the same width as void *.
14004 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14005 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14006 (current_message_1, set_message_1):
14007 Use a local to convert to proper width without a cast.
14008 * xmenu.c (dialog_selection_callback): Likewise.
14010 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14011 Also, don't assume VALBITS / RAND_BITS is less than 5,
14012 and don't rely on undefined behavior when shifting a 1 left into
14014 * lisp.h (get_random): Change signature to match.
14016 * lread.c (hash_string): Use size_t, not int, for hash computation.
14017 Normally we prefer signed values; but hashing is special, because
14018 it's better to use unsigned division on hash table sizes so that
14019 the remainder is nonnegative. Also, size_t is the natural width
14020 for hashing into memory. The previous code used 'int', which doesn't
14021 retain enough info to hash well into very large tables.
14022 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14024 * dbusbind.c: Don't possibly lose pointer info when converting.
14025 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14026 Use XPNTR rather than XHASH, so that the high-order bits of
14027 the pointer aren't lost when converting through void *.
14029 * eval.c (Fautoload): Don't double-shift a pointer.
14031 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14033 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14035 * gnutls.c (DEF_GNUTLS_FN):
14036 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14038 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14040 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14043 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14045 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14046 New version that can reserve upto 2GB of heap space.
14048 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14050 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14052 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14054 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14055 `gnutls_certificate_set_x509_key_file'.
14057 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14059 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14060 Update dependencies.
14062 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14064 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14065 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14066 Remove unused parameter `fildes'.
14067 * process.c (read_process_output, send_process): Don't pass it.
14069 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14071 Fix previous change: the library cache is defined in w32.c.
14072 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14073 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14075 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14077 Implement dynamic loading of GnuTLS on Windows.
14079 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14080 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14081 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14084 * gnutls.c (Qgnutls_dll): Define.
14085 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14086 (gnutls_*): Declare function pointers.
14087 (init_gnutls_functions): New function to initialize function pointers.

14089 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
14090 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14091 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14092 (emacs_gnutls_write, emacs_gnutls_read)
14093 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14094 (Fgnutls_available_p): New function.
14095 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14096 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14097 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.

14107 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14108 (w32_delayed_load): Move from image.c. When loading a library, record
14109 its filename in the :loaded-from property of the library id.
14110 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14111 Initialize and staticpro them.
14112 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14114 * process.c: Include lisp.h before w32.h, not after.
14115 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14116 instead of gnutls_record_check_pending.
14118 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14120 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14122 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14123 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14126 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14128 * xterm.c (x_set_frame_alpha): Do not set property on anything
14129 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14131 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14133 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14135 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14137 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14149 * callproc.c: Indentation fixup.
14151 * sysdep.c (wait_for_termination_1): Make static.
14152 (wait_for_termination, interruptible_wait_for_termination):
14153 Move after wait_for_termination_1.
14155 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14157 * sysdep.c (interruptible_wait_for_termination): New function
14158 which is like wait_for_termination, but allows keyboard
14161 * callproc.c (Fcall_process): Add (:file "file") as an option for
14163 (Fcall_process_region): Ditto.
14165 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14167 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14168 rather than `XVECTOR (FOO)->size'.
14170 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14171 inttypes.h, as a gnulib replacement is used if it not available in
14174 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14176 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14177 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14178 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14180 * coding.c (coding_alloc_by_realloc): Error out if destination
14181 will grow beyond MOST_POSITIVE_FIXNUM.
14182 (decode_coding_emacs_mule): Abort if there isn't enough place in
14183 charbuf for the composition carryover bytes. Reserve an extra
14184 space for up to 2 characters produced in a loop.
14185 (decode_coding_iso_2022): Abort if there isn't enough place in
14186 charbuf for the composition carryover bytes.
14188 2011-04-21 Eli Zaretskii <eliz@gnu.org>

14191 aborting when %lld or %lll format is passed.
14192 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14193 %llo or %llx format is passed. (Bug#8545)
14195 * window.c (window_scroll_line_based): Use a marker instead of
14196 simple variables to record original value of point. (Bug#7952)
14198 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14199 produced by %s or %c overflows available buffer space. (Bug#8545)
14201 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14203 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

14232 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14234 * makefile.w32-in: Update dependencies.
14236 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14238 Improve `doprnt' and its usage. (Bug#8545)
14239 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14240 `format_end'. Remove support for %l as a conversion specifier.
14241 Don't use xrealloc. Improve diagnostics when the %l size modifier
14242 is used. Update the commentary.
14244 * eval.c (verror): Simplify calculation of size_t.
14246 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14249 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14251 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14254 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14256 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14257 This makes this file independent of the recent pseudovector change.
14259 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14261 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14263 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14264 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14265 Remove unused local.
14266 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14268 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14269 GCC 4.6.0 optimizes based on type-based alias analysis.
14270 For example, if b is of type struct buffer * and v of type struct
14271 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14272 != &v->size, and therefore "v->size = 1; b->size = 2; return
14273 v->size;" must therefore return 1. This assumption is incorrect
14274 for Emacs, since it type-puns struct Lisp_Vector * with many other
14275 types. To fix this problem, this patch adds a new type struct
14276 vectorlike_header that documents the constraints on layout of vectors
14277 and pseudovectors, and helps optimizing compilers not get fooled
14278 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14279 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14280 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14282 (XSETPVECTYPE): Rewrite in terms of new macro.
14283 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14284 This is a bit clearer, and further avoids the possibility of
14285 undesirable aliasing.
14286 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14287 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14288 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14289 since Lisp_Subr is a special case (no "next" field).
14290 (ASIZE): Now uses header.size rather than size.
14291 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14292 to avoid the hassle of writing XVECTOR (foo)->header.size.
14293 (struct vectorlike_header): New type.
14294 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14295 object, to help avoid aliasing.
14296 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14297 (SUBRP): Likewise, since Lisp_Subr is a special case.
14298 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14299 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14300 (struct Lisp_Hash_Table): Combine first two members into a single
14301 struct vectorlike_header member. All uses of "size" and "next" members
14302 changed to be "header.size" and "header.next".
14303 * buffer.h (struct buffer): Likewise.
14304 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14305 * frame.h (struct frame): Likewise.
14306 * process.h (struct Lisp_Process): Likewise.
14307 * termhooks.h (struct terminal): Likewise.
14308 * window.c (struct save_window_data, struct saved_window): Likewise.
14309 * window.h (struct window): Likewise.
14310 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14311 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14312 * buffer.c (init_buffer_once): Likewise.
14313 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14315 * process.c (Fformat_network_address): Use local var for size,
14318 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14320 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14321 * data.c (atof): Remove decl; no longer used or needed.
14322 (digit_to_number): Move to lread.c.
14323 (Fstring_to_number): Use new string_to_number function, to be
14324 consistent with how the Lisp reader treats infinities and NaNs.
14325 Do not assume that floating-point numbers represent EMACS_INT
14326 without losing information; this is not true on most 64-bit hosts.
14327 Avoid double-rounding errors, by insisting on integers when
14328 parsing non-base-10 numbers, as the documentation specifies.
14329 * lisp.h (string_to_number): New decl, replacing ...
14330 (isfloat_string): Remove.
14331 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14332 (read1): Do not accept +. and -. as integers; this
14333 appears to have been a coding error. Similarly, do not accept
14334 strings like +-1e0 as floating point numbers. Do not report
14335 overflow for integer overflows unless the base is not 10 which
14336 means we have no simple and reliable way to continue.
14337 Break out the floating-point parsing into a new
14338 function string_to_number, so that Fstring_to_number parses
14339 floating point numbers consistently with the Lisp reader.
14340 (digit_to_number): Move here from data.c. Make it static inline.
14341 (E_CHAR, EXP_INT): Remove, replacing with ...
14342 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14343 (string_to_number): New function, replacing isfloat_string.
14344 This function checks for valid syntax and produces the resulting
14345 Lisp float number too. Rework it so that string-to-number
14346 no longer mishandles examples like "1.0e+". Use strtoumax,
14347 so that overflow for non-base-10 numbers is reported only when
14348 there's no portable and simple way to convert to floating point.
14350 * textprop.c (set_text_properties_1): Rewrite for clarity,
14351 and to avoid GCC warning about integer overflow.
14353 * intervals.h (struct interval): Use EMACS_INT for members
14354 where EMACS_UINT might cause problems. See
14355 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14356 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14357 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14359 (offset_intervals): Tell GCC not to worry about length overflow
14360 when negating a negative length.
14362 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14363 (overrun_check_free): Likewise.
14365 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14366 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14369 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14370 (gnutls_make_error): Rename local to avoid shadowing.
14371 (gnutls_emacs_global_deinit): ifdef out; not used.
14372 (Fgnutls_boot): Use const for pointer to readonly storage.
14373 Comment out unused local. Fix pointer signedness problems.
14375 * lread.c (openp): Don't stuff size_t into an 'int'.
14376 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14377 about possible signed overflow.
14379 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14380 (GDK_KEY_g): Don't define if already defined.
14381 (xg_prepare_tooltip): Avoid pointer signedness problem.
14382 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14384 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14385 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14387 * xfns.c (Fx_window_property): Simplify a bit,
14388 to make a bit faster and to avoid GCC 4.6.0 warning.
14389 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14391 * fns.c (internal_equal): Don't assume size_t fits in int.
14393 * alloc.c (compact_small_strings): Tighten assertion a little.
14395 Replace pEd with more-general pI, and fix some printf arg casts.
14396 * lisp.h (pI): New macro, generalizing old pEd macro to other
14397 conversion specifiers. For example, use "...%"pI"d..." rather
14398 than "...%"pEd"...".
14399 (pEd): Remove. All uses replaced with similar uses of pI.
14400 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14401 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14402 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14403 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14404 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14405 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14406 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14408 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14409 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14410 * print.c (safe_debug_print, print_object): Likewise.
14411 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14413 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14414 avoiding the 0 flag, which is not portable.
14415 * process.c (Fmake_network_process): Use pI to avoid cast.
14416 * region-cache.c (pp_cache): Likewise.
14417 * xdisp.c (decode_mode_spec): Likewise.
14418 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14419 behavior on 64-bit hosts with printf arg.
14420 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14421 (x_stop_queuing_selection_requests): Likewise.
14422 (x_get_window_property): Don't truncate byte count to an 'int'
14425 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14426 here, since it parses constructs like leading '-' and spaces,
14427 which are not wanted; and it overflows with large numbers.
14428 Instead, simply match F[0-9]+, which is what is wanted anyway.
14430 * alloc.c: Remove unportable assumptions about struct layout.
14431 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14432 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14433 (allocate_vectorlike, make_pure_vector): Use the new macros,
14434 plus offsetof, to remove unportable assumptions about struct layout.
14435 These assumptions hold on all porting targets that I know of, but
14436 they are not guaranteed, they're easy to remove, and removing them
14437 makes further changes easier.
14439 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14440 This doesn't fix a bug but makes the code clearer.
14441 (string_overrun_cookie): Now const. Use initializers that
14442 don't formally overflow signed char, to avoid warnings.
14443 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14444 can cause Emacs to crash when string overrun checking is enabled.
14445 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14446 multiple of sizeof (EMACS_INT); it need not be, if
14447 alignof(EMACS_INT) < sizeof (EMACS_INT).
14448 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14450 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14456 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
14457 supposed to be handshaking. (Bug#8556)
14458 Reported by Paul Eggert <eggert@cs.ucla.edu>.
14460 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
14462 * lisp.h (Qdebug): List symbol.
14463 * eval.c (Qdebug): Restore global linkage.

14465 (handle_user_signal): Break into debugger when debug-on-event
14466 matches the current signal symbol.
14468 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
14470 * alloc.c (check_sblock, check_string_bytes)
14471 (check_string_free_list): Convert to standard C.
14473 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14475 * w32.c (emacs_gnutls_push): Fix typo.
14477 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14479 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14480 "cast to pointer from integer of different size".
14482 Improve doprnt and its use in verror. (Bug#8545)
14483 * doprnt.c (doprnt): Document the set of format control sequences
14484 supported by the function. Use SAFE_ALLOCA instead of always
14487 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14488 is one byte too soon. Don't use xrealloc; instead xfree and
14491 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14493 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14496 * gnutls.c: Renamed global_initialized to
14497 gnutls_global_initialized. Added internals for the
14498 :verify-hostname-error, :verify-error, and :verify-flags
14499 parameters of `gnutls-boot' and documented those parameters in the
14500 docstring. Start callback support.
14501 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14502 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14503 on error. Return error code.

14563 changes in globals.h immediately force recompilation.
14564 (TAGS): Depend on $(CURDIR)/m/intel386.h and
14565 $(CURDIR)/s/ms-w32.h.
14566 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

14575 * doprnt.c: Include limits.h.
14576 (SIZE_MAX): New macro.
14577 (doprnt): Return a size_t value. 2nd arg is now size_t.
14578 Many local variables are now size_t instead of int or unsigned.
14579 Improve overflow protection. Support `l' modifier for integer
14580 conversions. Support %l conversion. Don't assume an EMACS_INT
14581 argument for integer conversions and for %c.
14583 * lisp.h (doprnt): Restore prototype.
14585 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
14586 $(SRC)/character.h.
14588 * Makefile.in (base_obj): Add back doprnt.o.
14590 * deps.mk (doprnt.o): Add back prerequisites.
14591 (callint.o): Depend on character.h.
14593 * eval.c (internal_lisp_condition_case): Include the handler
14594 representation in the error message.
14595 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
14596 when breaking from the loop.
14598 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
14600 * callint.c (Fcall_interactively): When displaying error message
14601 about invalid control letter, pass the character's codepoint, not
14602 a pointer to its multibyte form. Improve display of the character
14603 in octal and display also its hex code.
14605 * character.c (char_string): Use %x to display the (unsigned)
14606 codepoint of an invalid character, to avoid displaying a bogus
14609 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
14610 `error', not SYMBOL_NAME itself.
14612 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
14613 character arguments to `error'.
14615 * charset.c (check_iso_charset_parameter): Fix incorrect argument
14616 to `error' in error message about FINAL_CHAR argument. Make sure
14617 FINAL_CHAR is a character, and use %c when it is passed as
14618 argument to `error'.

14682 Define only if needed.
14684 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
14685 by pacifying GCC about it. Maybe it's time to retire it?
14686 * xfaces.c (USG, __TIMEVAL__): Likewise.
14688 * dispextern.h (struct redisplay_interface): Rename param
14689 to avoid shadowing.
14690 * termhooks.h (struct terminal): Likewise.
14691 * xterm.c (xembed_send_message): Likewise.
14693 * insdel.c (make_gap_smaller): Define only if
14694 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
14696 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
14699 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
14700 so that we aren't warned about unused symbols.
14702 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
14704 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

14713 define if USE_GTK || USE_X_TOOLKIT.
14714 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
14715 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

14717 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
14719 * xmenu.c (menu_help_callback): Pointer type fixes.
14720 Use const pointers when pointing at readonly data. Avoid pointer

14736 * bitmaps: Change bitmaps from unsigned char back to the X11
14737 compatible char. Avoid the old compiler warnings about
14738 out-of-range initializers by using, for example, '\xab' rather
14741 * xgselect.c (xgselect_initialize): Check vs interface
14742 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

14807 * nsfont.m: Fixed bugs in ns_get_family and
14808 ns_descriptor_to_entity that were caused by using free to
14809 deallocate memory blocks that were allocated by xmalloc (via

14811 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
14812 --enable-checking=xmallocoverrun). xfree is now used to
14813 deallocate these memory blocks.

15213 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15214 Remove decls of unexported vars.
15215 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15217 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15219 Make Emacs functions such as Fatom 'static' by default.
15220 This makes it easier for human readers (and static analyzers)
15221 to see whether these functions can be called from other modules.
15222 DEFUN now defines a static function. To make the function external
15223 so that it can be used in other C modules, use the new macro DEFUE.
15224 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15225 (Finit_image_library):
15226 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15227 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15228 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15229 Remove decls, since these functions are now static.
15230 (Funintern, Fget_internal_run_time): New decls, since these functions
15231 were already external.
15233 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

15241 Mark functions with DEFUE instead of DEFUN,
15242 if they are used in other modules.
15243 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15244 decls for now-static functions.
15245 * buffer.h (Fdelete_overlay): Remove decl.
15246 * callproc.c (Fgetenv_internal): Mark as internal.
15247 * composite.c (Fremove_list_of_text_properties): Remove decl.

15255 * image.c (Finit_image_library): New forward static decl.
15256 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15257 * intervals.h (Fprevious_property_change):

15281 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15283 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15284 when at ZV. (Bug#8487)
15286 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15288 * charset.c (Fclear_charset_maps): Use xfree instead of free.

15299 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15301 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15302 since callers should never pass a negative size.
15303 Change the signature to match that of plain 'read' and 'write'; see
15304 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15305 * lisp.h: Update prototypes of emacs_write and emacs_read.
15307 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15309 * xdisp.c (redisplay_window): Don't try to determine the character
15310 position of the scroll margin if the window start point w->startp
15311 is outside the buffer's accessible region. (Bug#8468)
15313 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15315 Fix write-region and its subroutines for buffers > 2GB.
15316 * fileio.c (a_write, e_write): Modify declaration of arguments and
15317 local variables to support buffers larger than 2GB.
15318 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15320 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15321 argument, local variables, and return value.
15323 * lisp.h: Update prototypes of emacs_write and emacs_read.
15325 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15327 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15329 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15331 Fix more problems found by GCC 4.6.0's static checks.
15333 * xdisp.c (vmessage): Use a better test for character truncation.
15335 * charset.c (load_charset_map): <, not <=, for optimization,
15336 and to avoid potential problems with integer overflow.
15337 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15338 * casetab.c (set_identity, shuffle): Likewise.
15339 * editfns.c (Fformat): Likewise.
15340 * syntax.c (skip_chars): Likewise.
15342 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15343 This also lets GCC 4.6.0 generate slightly better loop code.
15345 * callint.c (Fcall_interactively): <, not <=, for optimization.
15346 (Fcall_interactively): Count the number of arguments produced,
15347 not the number of arguments given. This is simpler and lets GCC
15348 4.6.0 generate slightly better code.
15350 * ftfont.c: Distingish more carefully between FcChar8 and char.
15351 The previous code passed unsigned char * to a functions like
15352 strlen and xstrcasecmp that expect char *, which does not
15353 conform to the C standard.
15354 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15355 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15356 char * when the C standard requires it.
15358 * keyboard.c (read_char): Remove unused var.
15360 * eval.c: Port to Windows vsnprintf (Bug#8435).
15361 Include <limits.h>.
15362 (SIZE_MAX): Define if the headers do not.
15363 (verror): Do not give up if vsnprintf returns a negative count.
15364 Instead, grow the buffer. This ports to Windows vsnprintf, which
15365 does not conform to C99. Problem reported by Eli Zaretskii.
15366 Also, simplify the allocation scheme, by avoiding the need for
15367 calling realloc, and removing the ALLOCATED variable.
15369 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15371 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15372 But keep the doprint source code for now, as we might revamp it
15373 and use it again (Bug#8435).
15374 * lisp.h (doprnt): Remove.
15375 * Makefile.in (base_obj): Remove doprnt.o.
15376 * deps.mk (doprnt.o): Remove.
15378 error: Print 32- and 64-bit integers portably (Bug#8435).
15379 Without this change, on typical 64-bit hosts error ("...%d...", N)
15380 was used to print both 32- and 64-bit integers N, which relied on
15381 undefined behavior.
15382 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15383 * lisp.h (error, verror): Mark as printf-like functions.
15384 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15385 Report overflow in size calculations when allocating printf buffer.
15386 Do not truncate output string at its first null byte.
15387 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15388 Truncate the output at a character boundary, since vsnprintf does not
15390 * charset.c (check_iso_charset_parameter): Convert internal
15391 character to string before calling 'error', since %c now has the
15393 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15394 overflow when computing char to be passed to 'error'. Do not
15395 pass Lisp_Object to 'error'; pass the integer instead.
15396 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15397 formatted with plain %d.
15399 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15401 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15403 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15405 * xterm.c (x_catch_errors): Remove duplicate declaration.
15407 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15409 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15411 2011-04-10 Jim Meyering <meyering@redhat.com>
15413 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15414 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15415 return ssize_t not "int", and use size_t as the buffer length.
15416 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15417 * gnutls.h: Update declarations.
15418 * process.c (read_process_output): Use ssize_t, to match.
15419 (send_process): Likewise.
15421 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15423 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15425 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15427 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15428 Use unsigned char, to match FcChar8 type definition.
15430 * xterm.c (handle_one_xevent):
15431 * xmenu.c (create_and_show_popup_menu):
15432 * xselect.c (x_decline_selection_request)
15433 (x_reply_selection_request): Avoid type-punned deref of X events.
15435 2011-04-09 Eli Zaretskii <eliz@gnu.org>

15439 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15440 (scan_buffer, find_next_newline_no_quit)
15441 (find_before_next_newline, search_command, Freplace_match)
15442 (Fmatch_data): Make some `int' variables be EMACS_INT.
15444 * xdisp.c (display_count_lines): 3rd argument and return value now
15445 EMACS_INT. All callers changed.
15446 (pint2hrstr): Last argument is now EMACS_INT.
15448 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15449 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15450 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

15455 (decode_coding_iso_2022, decode_coding_emacs_mule)
15456 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15457 <char_offset, last_offset>: Declare EMACS_INT.

15461 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15462 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15464 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15465 (encode_invocation_designation): Last argument P_NCHARS is now
15467 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15468 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15470 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15473 * ccl.c (Fccl_execute_on_string): Declare some variables
15476 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15478 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15480 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15482 * process.c (Fformat_network_address): Doc fix.
15484 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15486 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15488 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15490 * keyboard.c (read_char): Call Lisp function help-form-show,
15491 instead of using internal_with_output_to_temp_buffer.
15492 (Qhelp_form_show): New var.
15493 (syms_of_keyboard): Use DEFSYM macro.
15495 * print.c (internal_with_output_to_temp_buffer): Function deleted.

15499 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15501 * process.c (Flist_processes): Remove to Lisp.
15502 (list_processes_1): Delete.
15504 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15506 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15508 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15510 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15512 Fix more problems found by GCC 4.6.0's static checks.
15514 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15516 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15518 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15520 * xdisp.c (vmessage): Mark as a printf-like function.
15522 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15524 * sound.c (sound_warning): Don't crash if arg contains a printf format.

15529 to system-supplied API.
15531 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15533 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15534 This avoids several warnings with gcc -Wstrict-overflow.
15535 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15536 directly, rather than having caller test rule sign. This avoids
15537 some unnecessary tests.
15538 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15539 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15540 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15542 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15543 (xfont_open): Avoid unnecessary tests.
15545 * composite.c (composition_gstring_put_cache): Use unsigned integer.

15554 by using the new macro.
15556 * textprop.c (set_text_properties_1): Change while to do-while,
15557 since the condition is always true at first.
15559 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15560 (interval_deletion_adjustment): Return unsigned value.
15563 * process.c (list_processes_1, create_pty, read_process_output):
15564 (exec_sentinel): Remove vars that were set but not used.
15565 (create_pty): Remove unnecessary "volatile"s.

15568 (read_process_output): Simplify nbytes computation if buffered.
15570 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
15572 * syntax.c (scan_words): Remove var that was set but not used.
15573 (update_syntax_table): Use unsigned instead of int.
15575 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
15576 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15577 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
15579 * print.c (print_error_message): Avoid int overflow.
15581 * font.c (font_list_entities): Redo for clarity,
15582 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15584 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15585 (font_score): Avoid potential overflow in diff calculation.
15587 * fns.c (substring_both): Remove var that is set but not used.
15588 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15590 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15592 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15593 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15594 can always succeed if overflow has undefined behavior.
15596 * search.c (boyer_moore, wordify): Remove vars set but not used.
15597 (wordify): Omit three unnecessary tests.
15599 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15600 All callers changed. This avoids the need for an unused var.
15602 * casefiddle.c (casify_region): Remove var that is set but not used.
15604 * dired.c (file_name_completion): Remove var that is set but not used.
15606 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
15608 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
15609 (Finsert_file_contents): Remove unnecessary code checking fd.
15611 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
15612 Check for integer overflow on size calculations.
15614 * buffer.c (Fprevious_overlay_change): Remove var that is set
15617 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
15618 Remove vars that are set but not used.
15619 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
15620 (timer_check_2): Mark vars as initialized.
15622 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
15624 * image.c (lookup_image): Remove var that is set but not used.
15625 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
15627 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
15628 that are set but not used.
15630 * xfns.c (make_invisible_cursor): Don't return garbage
15631 if XCreateBitmapFromData fails (Bug#8410).
15633 * xselect.c (x_get_local_selection, x_handle_property_notify):
15634 Remove vars that are set but not used.
15636 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
15637 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
15639 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
15640 Remove var that is set but not used.
15641 (scroll_bar_windows_size): Now size_t, not int.
15642 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
15643 Check for overflow.
15645 * xfaces.c (realize_named_face): Remove vars that are set but not used.
15646 (map_tty_color) [!defined MSDOS]: Likewise.
15648 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
15650 * coding.c: Remove vars that are set but not used.
15651 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

15658 that is set but not used.
15660 * print.c (print_object): Remove var that is set but not used.
15662 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
15663 The gnulib version avoids calling malloc in the usual case,
15664 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
15665 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
15666 * filelock.c (current_lock_owner): Likewise.
15667 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
15668 * sysdep.c: Include allocator.h, careadlinkat.h.
15669 (emacs_no_realloc_allocator): New static constant.
15670 (emacs_readlink): New function.
15671 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
15672 ../lib/careadlinkat.h.
15674 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
15676 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

15698 do not dereference NULL upon failed strdup
15699 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
15700 (ns_get_family): Likewise.
15702 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
15704 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
15706 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
15708 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
15711 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
15713 Add lexical binding.
15715 * window.c (Ftemp_output_buffer_show): New fun.

15724 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
15726 (syms_of_lread): Declare `lexical-binding'.
15728 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
15730 * keyboard.c (eval_dyn): New fun.
15731 (menu_item_eval_property): Use it.
15733 * image.c (parse_image_spec): Use Ffunctionp.
15735 * fns.c (concat, mapcar1): Accept byte-code-functions.
15737 * eval.c (Fsetq): Handle lexical vars.
15738 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
15739 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
15740 (FletX, Flet): Obey lexical binding.
15741 (Fcommandp): Handle closures.
15742 (Feval): New `lexical' arg.
15743 (eval_sub): New function extracted from Feval. Use it almost
15744 everywhere where Feval was used. Look up vars in lexical env.
15746 (Ffunctionp): Move from subr.el.
15747 (Ffuncall): Handle closures.
15748 (apply_lambda): Remove `eval_flags'.
15749 (funcall_lambda): Handle closures and new byte-code-functions.
15750 (Fspecial_variable_p): New function.
15751 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
15752 but without exporting it to Lisp.
15754 * doc.c (Fdocumentation, store_function_docstring):
15755 * data.c (Finteractive_form): Handle closures.
15757 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
15760 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
15762 (exec_byte_code): New function extracted from Fbyte_code to handle new
15763 calling convention for byte-code-functions. Add new byte-codes.
15765 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
15767 * alloc.c (Fmake_symbol): Init new `declared_special' field.
15769 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
15771 * xdisp.c (redisplay_internal): Fix prototype.
15773 2011-03-31 Eli Zaretskii <eliz@gnu.org>
15775 * xdisp.c (SCROLL_LIMIT): New macro.
15776 (try_scrolling): Use it when setting scroll_limit.
15777 Limit scrolling to 100 screen lines.
15778 (redisplay_window): Even when falling back on "recentering",
15779 position point in the window according to scroll-conservatively,
15780 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
15782 (try_scrolling): When point is above the window, allow searching
15783 as far as scroll_max, or one screenful, to compute vertical
15784 distance from PT to the scroll margin position. This prevents
15785 try_scrolling from unnecessarily failing when
15786 scroll-conservatively is set to a value slightly larger than the
15787 window height. Clean up the case of PT below the margin at bottom
15788 of window: scroll_max can no longer be INT_MAX. When aggressive
15789 scrolling is in use, don't let point enter the opposite scroll
15790 margin as result of the scroll.
15791 (syms_of_xdisp) <scroll-conservatively>: Document the
15792 threshold of 100 lines for never-recentering scrolling.

15799 (message_log_check_duplicate): Remove parameters `prev_bol' and
15800 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
15801 (redisplay_internal): Remove parameter `preserve_echo_area',
15802 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
15804 * indent.c (Fvertical_motion):
15805 * window.c (window_scroll_pixel_based, Frecenter):
15806 Don't pass `need_y_p' to `move_it_by_lines'.
15808 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
15810 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
15811 steal a few bits to be more compact.
15812 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
15813 Remove unneeded casts.
15815 * bytecode.c (Fbyte_code): CAR and CDR can GC.
15817 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
15819 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
15820 binding" message (bug#7967).
15822 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
15824 Fix more problems found by GCC 4.6.0's static checks.
15826 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
15827 Remove unused local var.
15829 * editfns.c (Fmessage_box): Remove unused local var.
15831 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
15832 (note_mode_line_or_margin_highlight, note_mouse_highlight):
15833 Omit unused local vars.
15834 * window.c (shrink_windows): Omit unused local var.
15835 * menu.c (digest_single_submenu): Omit unused local var.
15836 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
15837 Omit unused local var.
15839 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
15840 Don't assume string length fits in int.
15841 (keyremap_step, read_key_sequence): Use size_t for sizes.

15845 instead of alloca (Bug#8344).
15847 * eval.c (Fbacktrace): Don't assume nargs fits in int.
15848 (Fbacktrace_frame): Don't assume nframes fits in int.
15850 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

15857 * cm.c (calccost): Turn while-do into do-while, for clarity.
15859 * keyboard.c (syms_of_keyboard): Use the same style as later
15860 in this function when indexing through an array. This also
15861 works around GCC bug 48267.
15863 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
15865 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
15867 * chartab.c (sub_char_table_ref_and_range): Redo for slight
15868 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
15870 * keyboard.c, keyboard.h (num_input_events): Now size_t.
15871 This avoids undefined behavior on integer overflow, and is a bit
15872 more convenient anyway since it is compared to a size_t variable.
15874 Variadic C functions now count arguments with size_t, not int.
15875 This avoids an unnecessary limitation on 64-bit machines, which
15876 caused (substring ...) to crash on large vectors (Bug#8344).

15886 * fns.c (concat): Likewise.
15887 * frame.c (x_set_frame_parameters): Likewise.
15888 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
15889 0 if not found, not -1. All callers changed.
15891 * alloc.c (garbage_collect): Don't assume stack size fits in int.
15892 (stack_copy_size): Now size_t, not int.
15893 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
15895 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
15897 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
15898 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

15914 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
15915 don't set the hook to nil, but remove the offending function instead.
15916 (Qcommand_hook_internal): Remove, unused.
15917 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
15918 Vcommand_hook_internal.

15921 (funcall_nil, funcall_not): New functions.
15922 (run_hook_with_args): Call each function through a `funcall' argument.

16086 2011-03-23 Julien Danjou <julien@danjou.info>
16088 * term.c (Fsuspend_tty, Fresume_tty):
16089 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16090 * window.c (temp_output_buffer_show):
16091 * insdel.c (signal_before_change):
16092 * frame.c (Fhandle_switch_frame):
16093 * fileio.c (Fdo_auto_save):
16094 * emacs.c (Fkill_emacs):
16095 * editfns.c (save_excursion_restore):
16096 * cmds.c (internal_self_insert):
16097 * callint.c (Fcall_interactively):
16098 * buffer.c (Fkill_all_local_variables):
16099 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16101 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16102 unconditionally since it does the check itself.
16104 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16106 Fix more problems found by GCC 4.5.2's static checks.
16108 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16109 the first time through the loop, since we know p0 < p1 then.
16110 This also avoids a gcc -Wstrict-overflow warning.
16112 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16113 leading to a memory leak, possible in functions like
16114 load_charset_map_from_file that can allocate an unbounded number
16115 of objects (Bug#8318).
16117 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16118 that could (at least in theory) be that large.
16120 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16121 This is less likely to overflow, and avoids undefined behavior if
16122 overflow does occur. All callers changed. Use strtoul to scan
16123 for the unsigned long integer.
16124 (pint2hrstr): Simplify and tune code slightly.
16125 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16127 * scroll.c (do_scrolling): Work around GCC bug 48228.
16128 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16130 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16131 This also avoids a warning with gcc -Wstrict-overflow.
16132 (validate_x_resource_name): Simplify count usage.
16133 This also avoids a warning with gcc -Wstrict-overflow.
16135 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16138 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16140 * process.c (Fmake_network_process): Use socklen_t, not int,
16141 where POSIX says socklen_t is required in portable programs.
16142 This fixes a porting bug on hosts like 64-bit HP-UX, where
16143 socklen_t is wider than int (Bug#8277).
16144 (Fmake_network_process, server_accept_connection):
16145 (wait_reading_process_output, read_process_output):
16148 * process.c: Rename or move locals to avoid shadowing.

16158 Make tparam.h and terminfo.c consistent.
16159 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16160 Include tparam.h instead, since it declares them.
16161 * cm.h (PC): Remove extern decl; tparam.h now does this.
16162 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16163 * terminfo.c: Include tparam.h, to check interfaces.
16164 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16165 (tparam): Adjust signature to match interface in tparam.h;
16166 this removes some undefined behavior. Check that outstring and len
16167 are zero, which they always are with Emacs.
16168 * tparam.h (PC, BC, UP): New extern decls.
16170 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16171 (xftfont_open): Rename locals to avoid shadowing.
16173 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16174 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
16175 (OTF_TAG_SYM): Omit macro if not needed.

16183 * xml.c (make_dom): Now static.
16185 * composite.c (composition_compute_stop_pos): Rename local to
16187 (composition_reseat_it): Remove unused locals.
16188 (find_automatic_composition, composition_adjust_point): Likewise.
16189 (composition_update_it): Mark var as initialized.
16190 (find_automatic_composition): Mark vars as initialized,
16191 with a FIXME (Bug#8290).
16193 character.h: Rename locals to avoid shadowing.
16194 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16195 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16196 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16197 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16198 to avoid shadowing.
16200 * textprop.c (property_change_between_p): Remove; unused.
16202 * intervals.c (interval_start_pos): Now static.
16204 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16207 Rename locals to avoid shadowing.
16209 * sound.c (wav_play, au_play, Fplay_sound_internal):
16210 Fix pointer signedness.
16211 (alsa_choose_format): Remove unused local var.
16212 (wav_play): Initialize a variable to 0, to prevent undefined
16213 behavior (Bug#8278).
16215 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16217 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16219 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16220 clobbering (Bug#8298).
16221 * sysdep.c (sys_subshell): Likewise.
16222 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16224 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16225 This should get cleaned up, so that child_setup has the
16226 same signature on all platforms.
16228 * callproc.c (call_process_cleanup): Now static.
16229 (relocate_fd): Rename locals to avoid shadowing.
16231 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16233 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16234 not to be necessary, and produces flickering.
16236 2011-03-20 Glenn Morris <rgm@gnu.org>
16238 * config.in: Remove file.
16240 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16242 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16243 are now in src/globals.h.
16244 (syms_of_minibuf): Remove spurious & from previous change.
16246 2011-03-20 Leo Liu <sdl.web@gmail.com>
16248 * minibuf.c (completing-read-function): New variable.
16249 (completing-read-default): Rename from completing-read.
16250 (completing-read): Call completing-read-function.
16252 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16254 * xfaces.c (Fx_load_color_file):
16255 Read color file from absolute filename (bug#8250).
16257 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16259 * makefile.w32-in: Update dependencies.
16261 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16263 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16269 * process.c (make_serial_process_unwind, send_process_trap):
16270 (sigchld_handler): Now static.
16272 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16273 That way, the code declares only the vars that it needs.
16274 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16275 * s/cygwin.h (PTY_ITERATION): Likewise.
16276 * s/darwin.h (PTY_ITERATION): Likewise.

16280 * process.c (allocate_pty): Don't declare stb unless it's needed.
16282 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
16283 (CONSTANTLIM): Remove; unused.
16284 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16285 Define only if needed.
16287 * unexelf.c (unexec): Name an expression,
16288 to avoid gcc -Wbad-function-cast warning.
16289 Use a different way to cause a compilation error if anyone uses
16290 n rather than nn, a way that does not involve shadowing.
16291 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16293 * deps.mk (unexalpha.o): Remove; unused.
16295 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16296 * unexec.h: New file.
16297 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16298 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16299 Depend on unexec.h.
16300 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16301 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16302 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16303 Change as necessary to match prototype in unexec.h.
16305 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

16321 instead of using an uninitialized var.
16322 (font_sort_entities): Mark var as initialized.
16324 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16326 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16350 * callint.c (quotify_arg, quotify_args): Now static.
16351 (Fcall_interactively): Rename locals to avoid shadowing.
16352 Use const pointer when appropriate.
16354 * lisp.h (get_system_name, get_operating_system_release):

16358 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16359 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16360 some of which prompt warnings from gcc -Wbad-function-cast.
16361 (Fformat_time_string, Fencode_time, Finsert_char):
16362 (Ftranslate_region_internal, Fformat):
16363 Rename or remove local vars to avoid shadowing.
16364 (Ftranslate_region_internal): Mark var as initialized.
16366 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16369 * lisp.h (eassert): Check that the argument compiles, even if
16370 ENABLE_CHECKING is not defined.
16372 * data.c (Findirect_variable): Name an expression, to avoid
16373 gcc -Wbad-function-cast warning.
16374 (default_value, arithcompare, arith_driver, arith_error): Now static.

16382 Rename locals to avoid shadowing.
16383 (mark_stack): Move local variables into the #ifdef region where
16385 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16386 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16388 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16389 (GC_STRING_CHARS): Remove; not used.
16390 (Fmemory_limit): Cast sbrk's returned value to char *.
16392 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16393 avoids undefined behavior in theory.
16395 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16397 Use functions, not macros, for up- and down-casing (Bug#8254).
16398 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16399 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16400 to use the following functions instead of these macros.
16401 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16402 EMACS_INT, since callers assume the returned value fits in int.
16403 (upcase1): Likewise, for UPCASE_TABLE.
16404 (uppercasep, lowercasep, upcase): New static inline functions.
16405 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16406 the race-condition problem in the old DOWNCASE.
16408 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
16409 Rename locals to avoid shadowing.
16410 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16411 (regex_compile, re_search_2, re_match_2_internal):
16412 Remove unused local vars.
16413 (FREE_VAR): Rewrite so as not to use empty "else",
16414 which gcc can warn about.
16415 (regex_compile, re_match_2_internal): Mark locals as initialized.
16416 (RETALLOC_IF): Define only if needed.
16417 (WORDCHAR_P): Likewise. This one is never needed, but is used
16418 only in a comment talking about a compiler bug, so put inside
16419 the #if 0 of that comment.
16420 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16421 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16424 * search.c (boyer_moore): Rename locals to avoid shadowing.
16425 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16426 (PREV_CHAR_BOUNDARY): Likewise.
16428 * search.c (simple_search): Remove unused var.
16430 * dired.c (compile_pattern): Move decl from here ...

16436 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16438 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16439 Rename locals to avoid shadowing.
16440 (Fvertical_motion): Mark locals as initialized.
16442 * casefiddle.c (casify_object, casify_region): Now static.
16443 (casify_region): Mark local as initialized.
16445 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16447 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16448 New macros, so that the caller can use some names other than
16449 gcpro1, gcpro2, etc.
16450 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16452 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16453 argument, for consistency with GCPRO2_VAR, etc: it is now the
16454 prefix of the variable, not the variable itself. All uses
16456 * dired.c (directory_files_internal, file_name_completion):
16457 Rename locals to avoid shadowing.
16459 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16460 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16461 dired.c's scmp function, had undefined behavior.
16462 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16463 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16464 * buffer.h: ... to here, because these macros use current_buffer,
16465 and the new implementation with inline functions needs to have
16466 current_buffer in scope now, rather than later when the macros
16468 (downcase, upcase1): New static inline functions.
16469 (DOWNCASE, UPCASE1): Reimplement using these functions.
16470 This avoids undefined behavior in expressions like
16471 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16472 from race conditions in accessing the global variables
16473 case_temp1 and case_temp2.
16474 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16475 * lisp.h (case_temp1, case_temp2): Remove their decls.
16476 * character.h (ASCII_CHAR_P): Move from here ...
16477 * lisp.h: ... to here, so that the inline functions mentioned
16478 above can use them.
16480 * dired.c (directory_files_internal_unwind): Now static.
16482 * fileio.c (file_name_as_directory, directory_file_name):
16483 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16485 (file_name_as_directory): Use const pointers when appropriate.
16486 (Fexpand_file_name): Likewise. In particular, newdir might
16487 point at constant storage, so make it a const pointer.
16488 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16489 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16491 (Fset_file_times, Finsert_file_contents, auto_save_error):
16492 Rename locals to avoid shadowing.
16494 * minibuf.c (choose_minibuf_frame_1): Now static.
16495 (Ftry_completion, Fall_completions): Rename or remove locals
16496 to avoid shadowing.
16498 * marker.c (bytepos_to_charpos): Remove; unused.
16500 * lisp.h (verify_bytepos, count_markers): New decls,
16501 so that gcc does not warn that these functions aren't declared.
16503 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16504 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16505 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16506 (copy_text): Remove unused local var.
16508 * filelock.c (within_one_second): Now static.
16509 (lock_file_1): Rename local to avoid shadowing.
16511 * buffer.c (fix_overlays_before): Mark locals as initialized.
16512 (fix_start_end_in_overlays): Likewise. This function should be
16513 simplified by using pointers-to-pointers, but that's a different
16515 (switch_to_buffer_1): Now static.
16516 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16517 (report_overlay_modification): Rename locals to avoid shadowing.
16519 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
16520 Fix pointer signedness issue.
16521 (sys_subshell): Mark local as volatile if checking for lint,
16522 to suppress a gcc -Wclobbered warning that does not seem to be right.
16523 (MAXPATHLEN): Define only if needed.
16525 * process.c (serial_open, serial_configure): Move decls from here ...
16526 * systty.h: ... to here, so that they can be checked.
16528 * fns.c (get_random, seed_random): Move extern decls from here ...
