3 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4 left fringe if the window has a left margin. This avoids leaving
5 traces of the cursor because its leftmost pixel is not drawn over.
7 * dispnew.c (update_window_line): When the left margin area of a
8 screen line is updated, set the redraw_fringe_bitmaps_p flag of
9 that screen line. (Bug#12277)
11 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
13 Assume C89 or later for math functions (Bug#12381).
14 This simplifies the code, and makes it a bit smaller and faster,
15 and (most important) makes it easier to clean up signal handling
16 since we can stop worring about floating-point exceptions in
17 library code. That was a problem before C89, but the problem
18 went away many years ago on all practical Emacs targets.
19 * data.c, image.c, lread.c, print.c:
20 Don't include <math.h>; no longer needed.
21 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
22 might be autoconfigured, as that never happens.
24 * doprnt.c (DBL_MAX_10_EXP):
26 Remove. C89 or later always defines these.
27 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
28 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
29 (arith_error, domain_error, domain_error2):
30 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
31 no longer needed -- we simply return what C returns. All uses removed.
32 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
34 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
35 Remove. All uses expanded, as these macros are no longer used
36 more than once and are now more trouble than they're worth.
37 (Ftan): Use tan, not sin / cos.
38 (Flogb): Assume C89 frexp.
39 (fmod_float): Assume C89 fmod.
40 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
41 (init_floatfns): Remove. All uses removed.
43 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
45 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
46 compositeToPoint for OSX < 10.6 (Bug#12390).
48 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
50 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
51 This produces more-accurate results.
53 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
55 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
58 2012-09-08 Chong Yidong <cyd@gnu.org>
60 * syntax.c (Fstring_to_syntax): Doc fix.
62 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
64 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
65 in the internal border.
66 (x_set_window_size): Remove static variables and their usage.
67 (ns_redraw_scroll_bars): Fix NSTRACE arg.
68 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
69 fringe/internal border adjustment (Bug#11052).
70 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
71 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
72 (ns_fix_rect_ibw): Remove.
73 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
74 (ns_dumpglyphs_box_or_relief): Ditto.
75 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
77 (ns_dumpglyphs_image): Ditto.
78 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
80 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
81 their usage. Add fringe_extended_p and its use as in other terms.
82 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
83 scroll bar was removed.
84 (updateFrameSize): New function.
85 (windowDidResize): Move code to updateFrameSize and call it.
87 * nsterm.h (EmacsView): Add updateFrameSize.
89 2012-09-07 Chong Yidong <cyd@gnu.org>
91 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
93 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
95 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
97 More signal-handler cleanup (Bug#12327).
98 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
99 Problem introduced when merging patches. Noted by Eli Zaretskii in
100 <http://bugs.gnu.org/12327#67>.
101 * floatfns.c: Comment fix.
102 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
103 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
104 and anyway the declaration is harmless even if SIGDANGER is not defined.
105 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
106 defined BROKEN_FIONREAD). systty.h formerly did this, but other
107 source files not surprisingly expected syssignal.h to define, or
108 not define, SIGIO, and it's cleaner to do it that way, for consistency.
109 Include <sys/ioctl.h>, for FIONREAD.
110 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
111 This eliminates a problem whereby other files mysteriously had
112 to include "syssignal.h" before including "systty.h" if they
113 wanted to use "#ifdef SIGIO".
115 2012-09-07 Eli Zaretskii <eliz@gnu.org>
117 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
119 * w32.c (sigemptyset): Empty the set.
120 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
122 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
124 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
126 * alloc.c (mark_buffer): Revert unsafe marking optimization.
127 (mark_object): Likewise for frame objects.
129 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
131 * syssignal.h (handle_on_main_thread): Always declare,
132 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
133 This ports to platforms without HAVE_PTHREAD.
135 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
137 Signal-handler cleanup (Bug#12327).
138 Emacs's signal handlers were written in the old 4.2BSD style with
139 sigblock and sigmask and so forth, and this led to some
140 inefficiencies and confusion. Rewrite these to use
141 pthread_sigmask etc. without copying signal sets around. Also,
142 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
143 'signal', and instead use functions that do not attempt to take
144 over the system name space. This patch causes Emacs's text
145 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
146 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
147 Do not include <signal.h> or "syssignal.h", as these
148 modules do not use signals.
149 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
150 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
151 Do not include <signal.h>, as "syssignal.h" does that for us now.
152 * atimer.c (sigmask_atimers): New function.
153 (block_atimers, unblock_atimers): New functions,
154 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
156 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
157 no longer needed here.
158 * emacs.c (main): Inspect existing signal handler with sigaction,
159 so that there's no need to block and unblock SIGHUP.
160 * sysdep.c (struct save_signal): New member 'action', replacing
161 old member 'handler'.
162 (save_signal_handlers, restore_signal_handlers):
163 Use sigaction instead of 'signal' to save and restore.
164 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
165 New function. All users of 'signal' modified to use set_sighandler
166 if they're writeonly, and to use sys_signal if they're read+write.
167 (emacs_sigaction_init, forwarded_signal): New functions.
168 (sys_signal): Remove. All uses replaced by calls to sigaction
169 and emacs_sigaction_init, or by direct calls to 'signal'.
170 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
171 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
172 all uses replaced by pthread_sigmask etc. calls.
173 * syssignal.h: Include <signal.h>.
174 (emacs_sigaction_init, forwarded_signal): New decls.
175 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
176 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
177 (sigmask, sys_sigmask): Remove; no longer needed.
178 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
179 (sigblock, sigunblock, sigfree):
180 (sigsetmask) [!defined sigsetmask]:
181 Remove. All uses replaced by pthread_sigmask.
182 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
183 no longer need to be replaced, and its typical old uses
184 are now done via emacs_sigaction_init and sigaction.
185 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
186 (sys_sigdel): Remove; unused.
187 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
189 2012-09-06 Eli Zaretskii <eliz@gnu.org>
191 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
192 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
194 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
196 Explicitly mark buffer_defaults and buffer_local_symbols.
197 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
198 mark_local_symbols here.
199 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
200 since special buffers aren't marked here any more.
201 (allocate_buffer): Chain new buffer with all_buffers here...
202 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
204 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
205 (syms_of_buffer): Remove staticpro of the above.
206 (init_buffer_once): Set names for buffer_defaults and
207 buffer_local_symbols.
209 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
211 Use bool for booleans in font-related modules.
212 * font.c (font_intern_prop, font_style_to_value)
213 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
214 (generate_otf_features, font_check_otf_features, font_check_otf)
215 (font_match_p, font_list_entities, font_at):
216 * fontset.c (fontset_id_valid_p, reorder_font_vector
217 (fontset_find_font, Fset_fontset_font)
218 (face_suitable_for_char_p) [0]:
219 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
220 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
221 (m17n_flt_initialized, ftfont_shape_by_flt):
222 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
223 * nsfont.m (nsfont_draw):
224 * w32font.c (w32font_draw):
225 * w32term.c (x_draw_glyphless_glyph_string_foreground):
226 Use bool for booleans.
227 * font.h: Adjust to above API changes.
228 (struct font, struct font_driver, struct font_driver_list):
229 Use bool for booleans.
230 (struct font): Remove useless member encoding_type.
232 * fontset.c, xftfont.c: Omit unnecessary static decls.
234 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
236 * alloc.c (mark_object): Revert window marking code
237 since it's unsafe for the Fset_window_configuration.
239 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
241 Fix race conditions with signal handlers and errno (Bug#12327).
242 Be more systematic about preserving errno whenever a signal
243 handler returns, even if it's not in the main thread. Do this by
244 renaming signal handlers to distinguish between signal delivery
245 and signal handling. All uses changed.
246 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
247 * data.c (deliver_arith_signal): Rename from arith_error.
248 * dispnew.c (deliver_window_change_signal): Rename from
249 window_change_signal.
250 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
251 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
252 * keyboard.c (deliver_input_available_signal): Rename from
253 input_available_signal.
254 (deliver_user_signal): Rename from handle_user_signal.
255 (deliver_interrupt_signal): Rename from interrupt_signal.
256 * process.c (deliver_pipe_signal): Rename from send_process_trap.
257 (deliver_child_signal): Rename from sigchld_handler.
258 * atimer.c (handle_alarm_signal):
259 * data.c (handle_arith_signal):
260 * dispnew.c (handle_window_change_signal):
261 * emacs.c (handle_fatal_signal, handle_danger_signal):
262 * keyboard.c (handle_input_available_signal):
263 * keyboard.c (handle_user_signal, handle_interrupt_signal):
264 * process.c (handle_pipe_signal, handle_child_signal):
265 New functions, with the actual signal-handling code taken from the
266 original respective signal handlers, sans the sporadic attempts to
267 preserve errno, since that's now done by handle_on_main_thread.
268 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
269 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
270 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
272 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
273 Move initialization of main_thread to sysdep.c's init_signals.
274 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
275 our usage, and simplifies the mainline code.
276 (record_child_status_change): New static function, as a helper
277 for handle_child_signal, and with most of the old child handler's
279 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
280 (handle_child_signal): Use the above.
281 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
282 Moved here from emacs.c.
283 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
284 code moved here from emacs.c's main function.
285 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
286 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
287 lets callers save and restore errno properly.
289 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
291 Remove redundant or unused things here and there.
292 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
293 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
294 * editfns.c (Fcompare_buffer_substrings): Likewise.
295 * frame.h (struct terminal, struct font_driver_list):
296 Remove redundant declarations.
297 * window.h (Qleft, Qright): Likewise.
299 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
301 Do not mark objects from deleted buffers, windows and frames.
302 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
303 (mark_object): Likewise for windows and frames.
305 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
307 * alloc.c (valid_lisp_object_p): Treat killed buffers,
308 buffer_defaults and buffer_local_symbols as valid objects.
309 Return special value to denote them.
311 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
313 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
314 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
315 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
316 (file_name_absolute_p, Fsubstitute_in_file_name):
317 (check_executable, check_writable, Ffile_accessible_directory_p)
318 (Fset_file_selinux_context, Fdefault_file_modes)
319 (Finsert_file_contents, choose_write_coding_system)
320 (Fwrite_region, build_annotations, a_write, e_write)
322 * filelock.c (boot_time_initialized, get_boot_time)
323 (get_boot_time_1, lock_file_1, within_one_second):
324 * floatfns.c (in_float):
325 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
326 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
327 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
328 * lisp.h (struct Lisp_Hash_Table.cmpfn):
329 * window.c (compare_window_configurations):
330 Use bool for booleans.
331 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
332 (Fdefault_file_modes): Now mode_t, not int, for modes.
333 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
334 (internal_delete_file): Now returns void, not a (boolean) int,
335 since nobody was looking at the return value.
336 * lisp.h, window.h: Adjust to above API changes.
338 * xdisp.c (set_message): Simplify and reindent last change.
340 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
342 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
344 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
346 * eval.c (call_debugger): Make the function non-static so that we
347 can call it from set_message.
349 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
350 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
352 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
354 Give more-useful info on a fatal error (Bug#12328).
355 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
356 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
357 of doing the work ourselves.
358 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
360 (fatal_error_backtrace): New function, taken from the guts
361 of the old fatal_error_signal, but with a new option to output
363 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
364 info about the signal than just its number.
365 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
366 * sysdep.c: Include <execinfo.h>
367 (emacs_backtrace): New function, taken partly from the previous
368 code of the 'die' function.
369 (emacs_abort): Call fatal_error_backtrace rather than abort.
371 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
373 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
374 eager (load-time) macro-expansion.
375 * lisp.mk (lisp): Add macroexp.
377 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
379 Simplify redefinition of 'abort' (Bug#12316).
380 Do not try to redefine the 'abort' function. Instead, redo
381 the code so that it calls 'emacs_abort' rather than 'abort'.
382 This removes the need for the NO_ABORT configure-time macro
383 and makes it easier to change the abort code to do a backtrace.
384 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
385 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
386 Remove; sysdep.c's emacs_abort now takes its place.
387 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
388 'abort' changed to use 'emacs_abort'.
389 * msdos.c (dos_abort) [defined abort]: Remove; not used.
390 (abort) [!defined abort]: Rename to ...
391 (emacs_abort): ... new name.
392 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
393 the place of the old 'abort' in emacs.c.
394 * w32.c, w32fns.c (abort): Do not #undef.
395 * w32.c (emacs_abort): Rename from w32_abort.
397 2012-09-04 Eli Zaretskii <eliz@gnu.org>
399 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
400 offsets[j].dv, since the y axis of the screen coordinates points
401 down, while the y axis of the font definition coordinates points
402 up. This fixes display of Arabic diacritics such as KASRA and
403 KASRATAN. (Bug#11860)
405 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
407 Be more systematic about _setjmp vs setjmp.
408 * alloc.c (test_setjmp, mark_stack):
409 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
410 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
411 (png_load, my_error_exit, jpeg_load):
412 * process.c (send_process_trap, send_process):
413 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
414 The underscored versions are up to 30x faster on some hosts.
415 Formerly, the code used setjmp+longjmp sometimes and
416 _setjmp+_longjmp at other times, with no particular reason to
417 prefer setjmp+longjmp.
419 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
421 Fix minor problem found by static checking.
422 * buffer.c (Fdelete_all_overlays): Return nil.
424 2012-09-03 Martin Rudalics <rudalics@gmx.at>
426 * buffer.c (Fdelete_all_overlays): New function.
428 2012-09-03 Chong Yidong <cyd@gnu.org>
430 * gtkutil.c: Add extern decl for Qxft.
432 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
434 * emacs.c, eval.c: Use bool for boolean.
435 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
436 (malloc_using_checking) [DOUG_LEA_MALLOC]:
437 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
438 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
439 (main, decode_env_path, Fdaemon_initialized):
440 * eval.c (call_debugger, Finteractive_p, interactive_p):
441 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
442 (maybe_call_debugger, Fbacktrace):
443 * process.c (read_process_output, exec_sentinel):
444 Use bool for booleans.
445 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
447 * eval.c (interactive_p): Omit always-true boolean argument
448 EXCLUDE_SUBRS_P. All callers changed.
449 * dispextern.h, lisp.h: Reflect above API changes.
450 * firstfile.c (dummy): Use the address of 'main', whose signature

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

549 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
550 more than one grapheme cluster passed to the shaper: compute the
551 offset adjustment values separately for each cluster. (Bug#11860)
553 * image.c: Restore mistakenly removed inclusion of w32.h. Without
554 it, GCC doesn't see prototypes of w32_delayed_load, and complains
555 about implicit conversions from integer to pointer.
557 2012-09-01 Daniel Colascione <dancol@dancol.org>
559 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

613 window system declarations.
615 * frame.h: Move common functions here: set_frame_menubar,
616 x_set_window_size, x_sync, x_get_focus_frame,
617 x_set_mouse_position, x_set_mouse_pixel_position,
618 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

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

912 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
913 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
914 are all boolean, so make them single-bit bitfields.
916 * lisp.h (ASET): Remove attempt to detect side effects.
917 It was meant to be temporary and it often doesn't work,
918 because when IDX has side effects the behavior of IDX==IDX
919 is undefined. See Stefan Monnier in
920 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
922 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
924 * lisp.h (functionp): New function (extracted from Ffunctionp).
926 * eval.c (Ffunctionp): Use it.
928 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
930 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
931 as that's faster and simpler than static storage. Don't bother
932 with the g_main_context_query overhead if g_main_context_pending
933 says no events are pending.
934 (gfds, gfds_size): Remove these static vars.
935 (xgselect_initialize): Remove; no longer needed.
936 All uses and decls removed.
938 * emacs.c (fatal_error_signal_hook): Remove.
939 All uses removed. This leftover from old code was always 0.
941 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
942 * casefiddle.c (casify_object, casify_region):
943 * casetab.c (set_case_table):
944 * category.c, category.h (word_boundary_p):
945 * category.h (CHAR_HAS_CATEGORY):
946 Use bool for booleans, instead of int.
948 2012-08-25 Eli Zaretskii <eliz@gnu.org>
950 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
952 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
954 On assertion failure, print backtrace if available.
955 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
956 (die) [ENABLE_CHECKING]: Print a backtrace if available.
957 * Makefile.in (LIB_EXECINFO): New macro.
960 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
961 * bytecode.c (exec_byte_code):
962 * callint.c (check_mark, Fcall_interactively):
963 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
964 (getenv_internal, sync_process_alive, call_process_exited):
965 * lisp.h (USE_SAFE_ALLOCA):
966 Use bool for booleans, instead of int.
967 * lisp.h, process.h: Adjust prototypes to match above changes.
968 * callint.c (Fcall_interactively): Don't assume the mark's
969 offset fits in 'int'.
971 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
973 * buffer.c, buffer.h: Use bool for boolean.
974 * buffer.c (reset_buffer_local_variables)
975 (buffer_lisp_local_variables, Fset_buffer_modified_p)
976 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
977 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
978 (overlay_touches_p, overlay_strings, Foverlay_put)
979 (report_overlay_modification, call_overlay_mod_hooks):
980 (mmap_enlarge, mmap_set_vars):
981 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
982 Use bool for booleans, instead of int.
983 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
984 since the 1-or-0 return value is always ignored anyway.
985 (mmap_initialized_p):
986 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
987 * buffer.h, lisp.h: Adjust prototypes to match above changes.
989 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
991 * bidi.c: Use bool for boolean.
992 This is a bit more readable, and makes the text segment of bidi.o
993 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
994 Presumably it's faster too.
995 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
997 (bidi_cache_find_level_change, bidi_cache_iterator_state)
998 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
999 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1000 (bidi_explicit_dir_char, bidi_level_of_next_char)
1001 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1002 Use bool for booleans, instead of int.
1003 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1004 (bidi_unshelve_cache): Adjust decls to match code.
1006 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1008 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1011 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1013 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1014 * atimer.h: Include <stdbool.h>.
1016 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1018 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1019 compile time tests instead of run time tests on systems that do
1021 (FRAME_MAC_P): Remove leftover from deleted code.
1022 * frame.c (syms_of_frame): Remove leftover from deleted code.
1024 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1026 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1028 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1030 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1031 Otherwise, the compiler complains about (A?B:C) where B is void
1032 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1033 (fontset_add): Return void, for FONTSET_ADD.
1035 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1037 * alloc.c: Use bool for booleans.
1038 (gc_in_progress, abort_on_gc)
1039 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1040 (dont_register_blocks) [GC_MALLOC_CHECK]:
1041 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1042 (check_string_bytes, make_specified_string, memory_full)
1043 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1044 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1045 (mark_stack, valid_pointer_p, make_pure_string)
1046 (Fgarbage_collect, survives_gc_p, gc_sweep):
1047 Use bool for booleans, instead of int.
1048 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1049 Remove unused local.
1050 * alloc.c (PURE_POINTER_P):
1051 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1052 * editfns.c (Fformat):
1053 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1055 * fns.c (sweep_weak_table):
1056 * lisp.h (suppress_checking, push_message, survives_gc_p)
1057 (make_pure_string, gc_in_progress, abort_on_gc):
1058 * lread.c (readchar, read1):
1059 * print.c (Fprin1_to_string):
1060 * xdisp.c (push_message):
1061 Use bool for booleans affected directly or indirectly by
1064 Make recently-introduced setters macros.
1065 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1066 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1067 (set_fontset_default, set_fontset_fallback): Rename from their
1068 upper-case counterparts, and make them functions rather than macros.
1069 This is more consistent with the other recently-introduced setters.
1070 These don't need to be inline, since they're local.
1072 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1074 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1075 the loop (Bug#12247).
1077 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1079 * lisp.h (vcopy): Use memcpy rather than our own loop.
1080 This fixes a performance regression introduced by the recent
1081 addition of vcopy. This means 'vcopy' will need to be modified
1082 for a copying collector, but that's OK. Also, tighten the
1083 checking in the assertion.
1085 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1087 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1088 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1089 non-base glyph for the width of the base character, according to
1090 what x_draw_composite_glyph_string_foreground expects.
1091 Generate WADJUST value according to composition_gstring_width's
1092 expectations, to produce correct width of the composed character.
1093 Reverse the sign of the DU offset produced by ScriptPlace.
1095 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1097 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1099 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1101 Avoid direct writes to contents member of struct Lisp_Vector.
1102 * lisp.h (vcopy): New function to copy data into vector.

1104 * fns.c (Ffillarray): Use ASET.
1105 * keyboard.c (timer_check_2): Use AREF and ASET.
1106 (append_tool_bar_item, Frecent_keys): Use vcopy.
1107 * lread.c (read_vector): Use ASET.
1108 * msdos.c (Frecent_doskeys): Use vcopy.
1109 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1110 (Finternal_merge_in_global_face): Use ASET and vcopy.

1118 buffer to the specified position.
1120 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1122 Setter macros for fontsets.
1123 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1124 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1125 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1128 2012-08-20 Glenn Morris <rgm@gnu.org>
1130 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1131 Don't assume that `ln -f' works.
1133 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1135 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1136 and later about non-assignments with no effect. See discussion at
1137 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1140 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1142 Inline setter functions for Lisp_Objects slots of struct specbinding.
1143 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1146 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1148 * window.c (select_window): Always make selected window's buffer
1151 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1153 Use AREF and ASET for docstrings of category tables.
1154 * category.h (CATEGORY_DOCSTRING): Use AREF.
1155 (SET_CATEGORY_DOCSTRING): Use ASET.
1156 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1158 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1160 Inline setter functions for hash table members.
1161 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1162 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1163 (set_hash_key_and_value, set_hash_index, set_hash_next)
1164 (set_hash_hash): New functions.
1165 * charset.c, fns.c: Adjust users.
1167 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1169 Inline getter and setter functions for per-buffer values.
1170 * buffer.h (per_buffer_default, set_per_buffer_default)
1171 (per_buffer_value, set_per_buffer_value): New functions.
1172 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1173 * buffer.c, data.c: Adjust users.
1175 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1177 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1179 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1181 Rely on <config.h> + <unistd.h> to declare 'environ',
1182 as gnulib does this if the system doesn't.
1183 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1184 Remove declaration. MS-Windows declares it on stdlib.h which is
1185 included by conf_post.h.
1186 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1187 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1188 * vm-limit.c: Include <unistd.h>, for 'environ'.
1190 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1191 (start_of_data): Remove decl; mem-limits.h provides it.
1193 * xdisp.c (handle_invisible_prop): Make it a bit faster
1194 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1196 2012-08-19 Chong Yidong <cyd@gnu.org>
1198 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1201 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1203 * .gdbinit: Use call instead of set when calling a function in the
1206 * data.c (set_internal): Don't use set_blv_found.
1207 (Fkill_local_variable): Likewise.
1209 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1211 * nsfont.m (ns_ascii_average_width): Ensure the string
1212 ascii_printable is initialized with a null-terminated character
1213 array. Otherwise, it can contain undesired extra characters.
1215 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1217 port new setting code to Sun C 5.8 2005/10/13
1218 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1219 Return void, not Lisp_Object. Otherwise, the compiler
1220 complains about (A?B:C) where B is void and C is Lisp_Object
1221 when compiling CHAR_TABLE_SET, due to the recent change to
1222 the API of sub_char_table_set_contents.
1224 2012-08-18 Chong Yidong <cyd@gnu.org>
1226 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1227 for the string case (Bug#3874).
1229 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1231 * buffer.h (BSET): Remove (Bug#12215).

1307 (tset_charset_list, tset_selection_alist): New setter functions.
1308 * terminal.c (TERMHOOKS_INLINE):

1310 are compiled into code.
1311 (tset_param_alist): New setter function.
1313 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
1315 * keyboard.h (KSET): Remove (Bug#12215).

2055 * w32.c (init_environment): Change the default values of many
2056 environment variables in dflt_envvars[] to NULL, to avoid pushing
2057 them into environment when they were not already defined.
2058 Remove the code that deletes site-lisp subdirectories from the default
2059 value of EMACSLOADPATH, as it is no longer needed.
2060 (check_windows_init_file): Now external, not static.
2061 Use Vload_path as is, without adding anything, as this function is now
2062 called when Vload_path is already set up.

2066 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2111 * alloc.c (record_xmalloc): New function.
2112 * lisp.h (record_xmalloc): New decl.
2113 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2114 more like a function. This is because the pointer cast is not
2115 needed. All uses changed.
2116 * print.c (print_string, print_error_message): Avoid length recalc.
2118 Improve fix for macroexp crash with debugging (Bug#12118).
2119 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

2153 with addition of handling of symlinks and support for 'lstat'.
2154 If possible, get file's attributes and security information by

2156 called from 'lstat'.
2157 (stat, lstat): New functions, call 'stat_worker'.
2158 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2159 symlinks when the underlying filesystem supports them.

2163 Fix macroexp crash on Windows with debugging (Bug#12118).
2164 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2165 checking subscripts; problem introduced with the recent
2166 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2167 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2168 since it's used in non-static inline functions now.
2170 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2171 Don't assume buffer size fits in 'int'. Remove unused local.

2192 * dispnew.c (DISPEXTERN_INLINE):
2193 * sysdep.c (SYSTIME_INLINE):
2194 Define to EXTERN_INLINE, so that the corresponding functions
2195 are compiled into code.

2197 (INLINE_HEADER_END): New macros.
2198 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

2218 hard-coding the path separator.
2220 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
2222 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
2223 This how ASET and AREF are supposed to work, and makes
2224 it easier to think about future improvements. See
2225 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
2226 * charset.h (set_charset_attr): New function.

2695 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2697 Fast save_excursion_save and save_excursion_restore.
2698 * lisp.h (struct Lisp_Excursion): New data type.
2699 (PVEC_EXCURSION): New pseudovector type.
2700 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
2701 to deal with it. Adjust comments.

2715 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
2716 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
2717 emacs.c, as this is a more-suitable home. Had this been done earlier
2718 the fix for 12036 would have avoided some of the problems noted in
2719 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
2720 would have been more obvious.
2721 * emacs.c: Do not include <verify.h>; no longer needed.
2722 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
2723 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
2724 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2725 Remove; now done in lisp.h.
2726 * lisp.h (PUBLISH_TO_GDB): New macro.

2730 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
2731 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
2732 not be usable in #if. This simplifies things.
2734 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
2736 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

2741 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
2742 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
2743 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
2744 Adjust to changes in lisp.h and emacs.c, by using
2745 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
2746 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
2747 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
2748 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
2749 instead of gdb_valbits.
2750 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
2751 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
2752 instead of gdb_array_mark_flag.
2753 (xboolvector): Get size from $->size, not $->header.size.
2754 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
2755 (xreload, hook-run, hookpost-run): Remove.
2756 * emacs.c: Include <verify.h>.
2757 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
2758 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
2760 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
2761 (gdb_USE_LSB_TAG): New enum constants.
2762 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2763 Also define these as enum constants, so they're visible to GDB.
2764 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
2765 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
2766 as constants, so they're visible to GDB.

2768 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
2769 Now enum constants, not macros, so they're visible to GDB.
2770 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
2771 more convenient now. All uses changed.
2772 (VALMASK) [USE_LSB_TAG]: Also define in this case.
2773 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
2775 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

2782 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
2783 add argument, tune behavior, and adjust all callers.
2785 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
2787 Use typedef for EMACS_INT, EMACS_UINT.
2788 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
2789 than macros. This simplifies debugging in the usual case, since
2790 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
2791 and it allows expressions involving EMACS_INT casts.
2792 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
2794 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

2806 Adjust buffer text indirection counters at the end of Fkill_buffer.
2807 * buffer.c (Fkill_buffer): Adjust indirection counters when the
2808 buffer is definitely dead. This should really fix an issue reported
2809 by Christoph Scholtes again. (Bug#12007).
2810 (init_buffer_once): Initialize indirection counters of
2811 buffer_defaults and buffer_local_symbols (for sanity and safety).
2813 2012-07-24 Eli Zaretskii <eliz@gnu.org>
2815 * xdisp.c (init_iterator): Don't compute dimensions of truncation
2816 and continuation glyphs on tooltip frames, leave them at zero.

2844 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
2846 Swap buffer text indirection counters in Fbuffer_swap_text.
2847 * buffer.c (Fbuffer_swap_text): Swap indirections too.
2848 This avoids crash reported by Christoph Scholtes at
2849 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
2851 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
2853 * nsmenu.m (Popdown_data): New struct.

2876 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
2878 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
2879 as it's limited by the amount of memory, not by INT_MAX.
2881 2012-07-21 Eli Zaretskii <eliz@gnu.org>
2883 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
2884 in special-event-map. See the discussion at

3034 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3036 * eval.c (Fdefvar): Don't check constants since we only set the var if
3037 it's not yet defined anyway (bug#11904).
3039 * lisp.h (last_undo_boundary): Declare new var.
3040 * keyboard.c (command_loop_1): Set it.
3041 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3042 were auto-added by the command loop (bug#11774).

3606 Remove "#define unix" that is no longer needed (Bug#11905).
3607 * s/aix4-2.h (unix): Remove; no longer needed.
3609 EMACS_TIME simplification (Bug#11875).
3610 This replaces macros (which typically do not work in GDB)
3611 with functions, typedefs and enums, making the code easier to debug.
3612 The functional style also makes code easier to read and maintain.
3613 * systime.h: Include <sys/time.h> on all hosts, not just if
3614 WINDOWSNT, since 'struct timeval' is needed in general.
3615 (EMACS_TIME): Now a typedef, not a macro.
3616 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
3618 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
3619 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
3620 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
3621 (EMACS_TIME_LE): Now functions, not macros.
3622 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
3623 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
3624 which are not functions. All uses rewritten to use:
3625 (make_emacs_time): New function.
3626 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
3627 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
3628 not functions. All uses rewritten to use the following, respectively:
3629 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
3630 (add_emacs_time, sub_emacs_time): New functions.
3631 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
3632 * fileio.c (Fcopy_file):
3633 * xterm.c (XTflash): Get the current time closer to when it's used.
3634 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

3641 * frame.c (Fmake_terminal_frame):
3642 * gtkutil.c (get_utf8_string):
3644 * nsmenu.m (ns_update_menubar):
3645 * regex.c (regerror):
3646 Prefer memcpy to strncpy and strncat when either will do.
3647 * fileio.c (Fsubstitute_in_file_name):
3648 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
3649 (menu_separator_name_p):
3650 * nsmenu.m (ns_update_menubar):
3651 Prefer memcmp to strncmp when either will do.
3652 * nsterm.m: Include <ftoastr.h>.
3654 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
3655 Prefer snprintf to strncpy.
3656 * nsterm.m (ns_term_init):
3657 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
3658 * nsterm.m (ns_term_init):
3659 Avoid the need for strncpy, by using build_string or
3660 make_unibyte_string directly. Use dtoastr, not snprintf.
3661 * process.c (Fmake_network_process): Diagnose service names that
3662 are too long, rather than silently truncating them or creating
3663 non-null-terminated names.
3664 (Fnetwork_interface_info): Likewise, for interface names.
3665 * sysdep.c (system_process_attributes) [GNU_LINUX]:
3666 Prefer sprintf to strncat.
3667 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
3668 Prefer vsnprintf to vsprintf + strncpy.
3670 2012-07-10 Glenn Morris <rgm@gnu.org>
3672 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
3673 Clarify fallback case.
3675 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3677 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
3678 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
3679 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
3680 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
3681 where argument type is known to be a Lisp_Cons.
3683 2012-07-10 Tom Tromey <tromey@redhat.com>
3685 * bytecode.c (BYTE_CODE_THREADED): New macro.

3693 Optimize pure C strings initialization.
3694 * lisp.h (make_pure_string): Fix prototype.
3695 (build_pure_c_string): New function, defined as static inline. This
3696 provides a better opportunity to optimize away calls to strlen when
3697 the function is called with compile-time constant argument.
3698 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
3699 argument, adjust users accordingly. Use build_pure_c_string where
3701 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
3702 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
3703 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
3705 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3707 Avoid calls to strlen in miscellaneous functions.
3708 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
3709 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
3710 * lread.c (openp): Likewise.
3712 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3714 Avoid calls to strlen in path processing functions.
3715 * fileio.c (file_name_as_directory): Add comment. Change to add
3716 srclen argument and return the length of result. Adjust users
3718 (directory_file_name): Fix comment. Change to add srclen argument,
3719 swap 1st and 2nd arguments to obey the common convention.
3720 Adjust users accordingly.
3721 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
3723 2012-07-10 Glenn Morris <rgm@gnu.org>
3725 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
3726 Move PENDING_OUTPUT_COUNT definition to configure.
3728 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
3729 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
3730 * s/gnu.h (DATA_START): Move definitions to configure.
3732 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
3733 We include usg5-4-common.h, which defines them both.
3735 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
3736 O_RDONLY already includes it).
3738 Stop ns builds setting the EMACSLOADPATH environment variable.
3739 * nsterm.m (ns_load_path): Rename from ns_init_paths.
3740 Now it does not set EMACSLOADPATH, just returns the load-path string.
3741 * nsterm.h: Update accordingly.
3742 * lread.c [HAVE_NS]: Include nsterm.h.
3743 (init_lread) [HAVE_NS]: Use ns_load_path.
3744 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
3746 2012-07-09 Glenn Morris <rgm@gnu.org>
3748 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
3749 since the included bsd-common.h does so.
3751 Stop ns builds setting the EMACSPATH environment variable.
3752 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
3753 (ns_init_paths): Do not set EMACSPATH.
3754 * nsterm.h (ns_exec_path): Add it.
3755 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
3758 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
3760 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
3762 * process.c (wait_reading_process_output): 'waitchannels' was unset
3763 when read_kbd || !NILP (wait_for_cell); fix this.
3765 Add GCC-style 'const' attribute to functions that can use it.
3766 * character.h (char_resolve_modifier_mask):
3767 * keyboard.h (make_ctrl_char):
3768 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
3769 (init_character_once, next_almost_prime, init_fns, init_image)
3770 (flush_pending_output, init_sound):
3771 * mem-limits.h (start_of_data):

3775 Declare the dummy function with ATTRIBUTE_CONST.
3776 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
3777 Add decls with ATTRIBUTE_CONST.
3779 Minor improvements to make_formatted_string.
3780 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
3781 where int is good enough, as vsprintf returns an int.
3782 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
3784 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3786 Use make_formatted_string to avoid double length calculation.
3787 * lisp.h (make_formatted_string): New prototype.
3788 * alloc.c (make_formatted_string): New function.
3789 * buffer.c (Fgenerate_new_buffer_name): Use it.
3790 * dbus.c (syms_of_dbusbind): Likewise.

3793 * frame.c (make_terminal_frame, set_term_frame_name)
3794 (x_report_frame_params): Likewise.
3795 * image.c (gs_load): Likewise.
3796 * minibuf.c (get_minibuffer): Likewise.

3811 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3813 Move marker debugging code under MARKER_DEBUG.
3814 * marker.c (MARKER_DEBUG): Move marker debugging code under
3815 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
3816 for bootstrap with --enable-checking (~3x slowdown reported
3817 by Juanma Barranquero <lekktu@gmail.com>).
3818 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
3820 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
3822 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
3823 See <http://bugs.gnu.org/11825#29>.
3825 2012-07-08 Eli Zaretskii <eliz@gnu.org>
3827 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
3828 has no font, use the frame's font. (Bug#11813)
3829 (display_line): Add commentary about displaying truncation glyphs
3831 (produce_special_glyphs): Move here from term.c.
3833 * term.c (produce_special_glyphs): Move to xdisp.c.
3835 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
3838 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
3840 * xdisp.c (display_line): Avoid warning about implicit declaration
3843 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
3845 * lisp.h: Remove empty conditional.
3847 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3849 * lread.c (load_path_check): Now static.
3851 Fix some minor --with-ns problems found by static checking.
3852 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
3853 (x_set_font) [!HAVE_X_WINDOWS]:
3854 * image.c (xpm_load_image) [HAVE_NS]:
3855 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
3856 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
3857 Remove unused local.
3858 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
3859 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
3860 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
3861 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
3862 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
3863 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
3864 Fix pointer signedness problem.
3865 * xfaces.c (FRAME_X_FONT_TABLE):
3866 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
3868 2012-07-07 Glenn Morris <rgm@gnu.org>
3870 * lread.c (load_path_check): New function, split from init_lread.
3871 (init_lread): Reorganize. Motivation:
3872 If EMACSLOADPATH is set, check/warn about that rather than the
3873 defaults, which we are not going to use. Hence we can remove
3874 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
3875 Don't warn if site-lisp directories are missing.
3876 If not installed, start from a blank load-path, since
3877 PATH_LOADSEARCH refers to the eventual installation directories.
3879 2012-07-07 Eli Zaretskii <eliz@gnu.org>
3881 Support truncation and continuation glyphs on GUI frames, when
3882 fringes are disabled. (Bug#11832)
3883 * xdisp.c (init_iterator): Get dimensions of truncation and
3884 continuation glyphs even if on GUI frames.
3885 Adjust it->last_visible_x on GUI frames when the left or right fringes,
3886 or both, are absent.
3887 (start_display, move_it_in_display_line_to): Handle the case of a
3888 GUI frame without a fringe to display continuation or truncation
3890 (insert_left_trunc_glyphs): Support GUI frames: make sure
3891 truncation glyphs overwrite enough glyphs from the current line to
3892 have sufficient space in pixels.
3893 (display_line): Support truncation and continuation glyphs on GUI
3894 frames. If some spare pixels are left on the line after inserting
3895 the truncation glyphs, fill that space with a stretch glyph of a
3896 suitably computed width.
3898 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
3899 produce_glyphs, to support GUI sessions.
3901 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3903 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
3905 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
3907 Do not require float-time's arg to fit in time_t (Bug#11825).
3908 This works better on hosts where time_t is unsigned, and where
3909 float-time is applied to the (negative) difference between two times.
3910 * editfns.c (decode_time_components): Last arg is now double *,
3911 not int *, and means to store all the result as a double, without
3912 worrying about whether the seconds part fits in time_t.
3913 All callers changed.
3914 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
3915 All callers changed.
3916 (Ffloat_time): Do not fail merely because the specified time falls
3917 outside of time_t range.
3919 2012-07-07 Glenn Morris <rgm@gnu.org>
3921 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

3925 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
3927 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
3928 Update dependencies.
3930 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
3932 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3934 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
3935 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
3936 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3937 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
3938 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
3939 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
3941 * xfont.c (compare_font_names): Redo to omit the need for casts.
3943 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
3945 * xfns.c (Fx_change_window_property): Doc fix.
3946 * w32fns.c (Fx_change_window_property): Doc fix.
3948 * w32fns.c (Fx_window_property): Accept the same arguments as the
3949 X Windows version. Doc fix.
3950 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3952 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3953 Eli Zaretskii <eliz@gnu.org>
3955 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
3956 Windows-specific code from nt/config.nt moved here.
3957 Obsolete settings removed.
3959 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3961 * process.c: Avoid unnecessary calls to gettime.
3962 (wait_reading_process_output): Don't get the time of day
3963 when gobbling data immediately and not waiting, as there's no need
3964 for it in that case. This removes a FIXME.
3966 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
3968 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
3969 is defined (Bug#11768).

3975 if buffer is not multibyte.
3976 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3977 Call byte_char_debug_check with correct arguments.
3979 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3981 Compile marker debugging code only if ENABLE_CHECKING is defined.
3982 * marker.c (byte_char_debug_check, count_markers):
3983 Use only if ENABLE_CHECKING is defined.
3984 (byte_debug_flag): Remove.
3985 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3986 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
3988 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3990 Avoid code repetition in marker-related functions.
3991 * marker.c (attach_marker): New function.
3992 (Fset_marker, set_marker_restricted, set_marker_both)
3993 (set_marker_restricted_both): Use it.

4016 * window.c (save_window_save): Likewise.
4018 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4020 Do not use Fdelete_overlay in delete_all_overlays
4021 to avoid redundant calls to unchain_overlay.
4022 * buffer.c (drop_overlay): New function.
4023 (delete_all_overlays, Fdelete_overlay): Use it.
4024 * minibuf.c (get_minibuffer): Fix comment.
4026 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4028 Port to OpenBSD 5.1 amd64.
4029 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4030 This is needed for OpenBSD, and should be harmless on all BSD systems.
4031 Also, include <sys/sysctl.h>, as it should be available on all
4032 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4033 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4034 use p_pid member, not kp_proc.pid.
4036 2012-07-06 Glenn Morris <rgm@gnu.org>
4038 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4040 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4042 More xmalloc and related cleanup.
4043 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
4044 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

4050 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4051 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4053 Omit needless casts involving void * pointers and allocation.
4054 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4055 as the former is more robust if P's type is changed.
4056 Prefer xzalloc to xmalloc + memset 0.
4057 Simplify malloc-or-realloc to realloc.
4058 Don't worry about xmalloc returning a null pointer.
4059 Prefer xstrdup to xmalloc + strcpy.
4060 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4062 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4063 alloca of a constant.
4065 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4067 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4068 hscroll is larger than the line width. Fixes long and futile
4069 looping inside extend_face_to_end_of_line (on a TTY) producing
4070 glyphs that are not needed and thrown away.
4072 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4074 * marker.c (set_marker_restricted_both): Simplify by using
4077 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4079 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4081 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4083 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4084 not defined (Bug#11768).
4085 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4086 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4087 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4088 followed by gtk_box_set_homogeneous (Bug#11768).
4089 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4090 (update_theme_scrollbar_width, xg_create_scroll_bar):
4091 Use gtk_scrollbar_new (Bug#11768).
4092 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4093 (is_box_type): New function (Bug#11768).
4094 (xg_tool_item_stale_p): Call is_box_type.
4095 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4096 with default display (Bug#11768).

4100 * xdisp.c (window_hscroll_limited): New function.
4101 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4102 coordinates when window's hscroll is set to insanely large
4105 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4107 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4108 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4110 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4113 * lisp.h (xzalloc): New prototype. Omit needless casts.
4114 * alloc.c (xzalloc): New function. Omit needless casts.

4168 * fileio.c (time_error_value): Check the right error number.
4169 Problem reported by Troels Nielsen in
4170 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4172 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4174 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4175 This should be fixed in a better way; see Eli Zaretskii in
4176 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4177 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4179 * fileio.c (time_error_value): Rename from special_mtime.
4180 The old name's problems were noted by Eli Zaretskii in
4181 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4183 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4184 This variable's comment says Emacs needs at least one GDB-visible
4185 symbol of type enum pvec_type, to work around GDB problems.
4186 The symbol's value doesn't matter.
4188 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4189 that causes compilation to fail on pre-C99 compilers.
4191 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4193 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4194 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4196 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4198 * buffer.c (init_buffer_once): Fix initialization of
4199 headers for buffer_defaults and buffer_local_symbols.
4200 Reported by Juanma Barranquero <lekktu@gmail.com>.
4202 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4204 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4205 * lisp.h (enum pvec_type): Use fewer bits.
4206 (PSEUDOVECTOR_SIZE_BITS): New constant.
4207 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4208 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4209 change in pvec_type.
4210 (PSEUDOVECTOR_TYPEP): New macro.
4211 (TYPED_PSEUDOVECTORP): Use it.
4212 * fns.c (internal_equal): Adapt code to extract pvectype.
4213 * emacs.c (gdb_pvec_type): Update type.
4214 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4215 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4216 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4217 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4218 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4219 abusing vector->header.next.nbytes.
4220 (live_vector_p): Use PVEC_TYPE.
4221 (mark_object): Adapt code to extract pvectype. Use switch.
4223 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4225 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4226 Tighten new eassert a bit.
4228 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4230 Fix compilation with --enable-gcc-warnings and -O1
4232 * doprnt.c (doprnt): Change type of tem to int, initialize
4233 to avoid compiler warning. Add eassert.
4234 * search.c (simple_search): Initialize match_byte to avoid
4235 compiler warning. Add eassert.
4237 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4239 Avoid weird behavior with large horizontal scrolls.
4240 Without this change, for example, large hscroll values would
4241 mess up Emacs's display on Fedora 15 x86, presumably due to
4242 overflows in int calculations in the display code.
4243 Also, if buffers had long lines, Emacs would freeze.
4244 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4245 (set_window_hscroll): New function, containing the old guts of
4246 Fset_window_hscroll. Return the clipped value.
4247 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4248 This avoids the need to check against PTRDIFF_MAX.
4250 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4252 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4254 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4256 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4258 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4259 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4260 since GCC 4.4.6 issues a bogus warning for them.
4262 Fix bugs in file timestamp newness comparisons.
4263 * fileio.c (Ffile_newer_than_file_p):
4264 * lread.c (Fload): Use full timestamp resolution of files,
4265 not just the 1-second resolution, so that files that are only
4266 slightly newer still count as newer.
4267 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4268 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4270 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4272 * fileio.c: Improve handling of file time marker. (Bug#11852)
4273 (special_mtime): New function.
4274 (Finsert_file_contents, Fverify_visited_file_modtime):
4275 Use it to set special mtime values consistently.
4277 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4279 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4280 marker for non-existing file. (Bug#11852)
4282 2012-07-03 Glenn Morris <rgm@gnu.org>
4284 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4285 and did not make it into globals.h).
4287 2012-07-03 Tom Tromey <tromey@redhat.com>
4289 * window.c (Fset_window_margins, Fset_window_fringes)
4290 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4291 * textprop.c (Fprevious_property_change): No longer static.
4292 * syntax.c (Fsyntax_table_p): No longer static.
4293 * process.c (Fget_process, Fprocess_datagram_address): No longer

4313 * dispextern.h: Remove EXFUNs.
4314 * intervals.h: Remove EXFUNs.
4315 * fontset.h: Remove EXFUN.
4316 * font.h: Remove EXFUNs.
4317 * dosfns.c (system_process_attributes): Remove EXFUN.
4318 * keymap.h: Remove EXFUNs.
4319 * lisp.h: Remove EXFUNs.
4320 * w32term.h: Remove EXFUNs.
4321 * window.h: Remove EXFUNs.
4322 * xsettings.h: Remove EXFUN.
4323 * xterm.h: Remove EXFUN.
4325 2012-07-03 Glenn Morris <rgm@gnu.org>
4327 * lisp.h (Frandom): Make it visible to C.
4328 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4329 buffer for invisible buffers. (Bug#1229)
4331 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4333 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4334 values which aren't power of 2.
4335 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4336 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4339 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4341 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4343 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4345 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4347 * alloc.c (allocate_vector_block): Remove redundant
4348 calls to mallopt if DOUG_LEA_MALLOC is defined.
4349 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4350 avoid calls to mallopt if zero_vector is returned.
4352 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4354 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4355 is enabled, avoid dereferencing NULL current_sblock if
4358 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4360 Cleanup basic buffer management.
4361 * buffer.h (struct buffer): Change layout to use generic vector
4362 marking code. Fix some comments. Change type of 'clip_changed'
4363 to bitfield. Remove unused #ifndef old.
4364 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4365 (GET_OVERLAYS_AT): Fix indentation.
4366 (for_each_per_buffer_object_at): New macro.
4367 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4368 (Fbuffer_local_variables): Use it.
4369 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4370 * alloc.c (allocate_buffer): Adjust to match new layout of
4371 struct buffer. Fix comment.
4372 (mark_overlay): New function.
4373 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4374 Lisp area of struct buffer.
4375 (mark_object): Use it. Adjust marking of misc objects
4376 and related comments.
4378 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4380 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4381 wrapper that is not needed because the wrapped code is a no-op (zero
4382 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4383 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4385 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4387 * alloc.c (mark_buffer): Simplify. Remove prototype.
4388 (mark_object): Add comment. Reorganize marking of vector-like
4389 objects. Use CHECK_LIVE for all vector-like objects except buffers
4390 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4391 Avoid redundant calls to mark_vectorlike for bool vectors.
4393 2012-06-30 Glenn Morris <rgm@gnu.org>
4395 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4397 * epaths.in (PATH_SITELOADSEARCH): New.
4398 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4399 This is rather than relying on --enable-locallisppath elements
4400 having "site-lisp" in their names. (Bug#10208#25, 11658)
4402 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4404 * w32proc.c (sys_select): Accept and ignore one more argument.
4406 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4408 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4409 (pselect) [!MS_DOS]: Redirect to sys_select.
4411 * sysdep.c: Don't include dos.h and dosfns.h.
4413 * process.c (sys_select):
4414 * msdos.c (sys_select): Accept one more argument and ignore it.
4416 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4417 adapt data types and code to that.
4420 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4421 which clashes with the gnulib function of the same name.
4423 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4425 * font.c (font_style_to_value, font_style_symbolic)
4426 (font_prop_validate_style): Add type checks for values in
4429 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4431 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4434 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4436 * xdisp.c (try_window_id): Undo last change.
4438 * w32.c (getwd): Adjust commentary about startup_dir.
4439 (init_environment): Always call sys_access, even in non-MSVC
4440 builds. Don't chdir to the directory of the Emacs executable.
4441 This undoes code from 1997 which was justified by the need to
4442 "avoid conflicts when removing and renaming directories". But its
4443 downside was that every relative file name was being interpreted
4444 relative to the directory of the Emacs executable, which can never
4445 be TRT. In particular, it broke sys_access when called with
4446 relative file names.
4447 (sys_access): Map GetLastError to errno.
4449 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4451 * window.h (struct window): Change type of 'fringes_outside_margins'
4452 to bitfield. Fix comment. Adjust users accordingly.
4453 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
4455 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4458 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4460 * gnutls.c (emacs_gnutls_handshake):
4461 Add QUIT to make the loop interruptible.
4463 2012-06-29 Glenn Morris <rgm@gnu.org>
4465 * charset.c (init_charset): Make lack of etc/charsets fatal.
4467 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4469 * editfns.c (region_limit): Fix type mismatch.
4471 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4473 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4474 undefined. Convert from xassert to eassert.
4475 * nsmenu.m: Convert from xassert to eassert.
4476 * nsterm.m: Likewise.
4478 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
4480 * editfns.c (region_limit): Clip to narrowing (bug#11770).
4482 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
4484 Avoid integer overflow on scroll-left and scroll-right.
4485 * window.c (HSCROLL_MAX): New macro.
4486 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
4487 overflow when requested scroll falls outside ptrdiff_t range.
4489 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
4491 * window.h (struct window): Change type of 'hscroll',
4492 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
4493 'last_modified' and 'last_overlay_modified' to EMACS_INT.
4494 Adjust users accordingly.
4495 * xdisp.c (try_cursor_movement): Replace type check with eassert.
4496 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
4497 from EMACS_INT to ptrdiff_t.
4498 (make_window): Omit redundant initialization.
4500 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
4502 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.

4641 Use sprintf return value instead of invoking strlen on result.
4642 In the old days this wasn't portable, since some sprintf
4643 implementations returned char *. But they died out years ago and
4644 Emacs already assumes sprintf returns int.
4645 Similarly for float_to_string.
4646 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

4654 Use sprintf or float_to_string result to avoid need to call strlen.
4655 * data.c (Fnumber_to_string):
4656 Use make_unibyte_string, since the string must be ASCII.
4657 * lisp.h, print.c (float_to_string): Now returns int length.
4658 * term.c (produce_glyphless_glyph):
4659 Use sprintf result rather than recomputing it.
4661 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

4692 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
4694 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

4697 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
4699 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
4700 instead of truncating it to 63 (admittedly a generous limit).

4760 * keyboard.c (kbd_buffer_get_event):
4761 * process.c (Faccept_process_output):
4762 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
4763 This improves on the previous patch, which introduced a bug
4764 when time_t is unsigned and as wide as intmax_t.
4765 See <http://bugs.gnu.org/9000#51>.
4767 2012-06-23 Eli Zaretskii <eliz@gnu.org>

4796 language ID in the event parameters.
4798 * w32term.c (w32_read_socket): Put the new keyboard codepage into

4822 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
4823 Privately reported by Herbert J. Skuhra.

4830 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
4832 Support higher-resolution time stamps (Bug#9000).
4833 The time stamps are only nanosecond-resolution at the C level,
4834 since that's the best that any real-world system supports now.
4835 But they are picosecond-resolution at the Lisp level, as that's
4836 easy, and leaves room for future OS improvements.
4838 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
4841 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
4842 Don't get current time unless it's needed.
4844 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
4845 now provides it if it's absent.
4846 (start_atimer): Port to higher-res time stamps.
4847 Check for time stamp overflow. Don't get current time more
4848 often than is needed.
4850 * buffer.h (struct buffer): Buffer modtime now has high resolution.
4851 Include systime.h, not time.h.
4852 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
4854 * dired.c: Include stat-time.h.
4855 (Ffile-attributes): File times now have higher resolution.

4858 (struct image): Timestamp now has higher resolution.
4860 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
4861 has at least microseconds now. All uses removed.
4862 (update_frame, update_single_window, update_window, update_frame_1)
4863 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
4864 (duration_to_sec_usec): Remove; no longer needed.
4866 * editfns.c (time_overflow): Now extern.
4867 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
4868 (float-time, Fformat_time_string, Fcurrent_time_string)

4872 (decode_time_components, lisp_seconds_argument): New functions.
4873 (make_time): Now static.
4874 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
4875 Report an error if the time is invalid, rather than having the caller
4878 * fileio.c: Include <stat-time.h>
4879 (Fcopy_file): Copy higher-resolution time stamps.
4880 Prefer to set the time stamp via a file descriptor if that works.
4881 (Fset_file_times, Finsert_file_contents, Fwrite_region)
4882 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
4883 (Fvisited_file_modtime, Fset_visited_file_modtime):
4884 Support higher-resolution time stamps.
4886 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
4888 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
4890 * image.c (prepare_image_for_display, clear_image_cache)
4891 (lookup_image): Port to higer-resolution time stamps.
4893 * keyboard.c (start_polling, bind_polling_period):
4894 Check for time stamp overflow.
4895 (read_char, kbd_buffer_get_event, timer_start_idle)
4896 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
4897 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
4898 Port to higher-resolution time stamps. Do not assume time_t is signed.
4899 (decode_timer): New function. Timers are now vectors of length 9,
4900 not 8, to accommodate the picosecond component.
4901 (timer_check_2): Use it.
4903 * nsterm.m (select_timeout, timeval_subtract): Remove.
4904 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
4905 as they're a bit more accurate and handle overflow better.
4906 (ns_select): Change prototype to be compatible with pselect.
4907 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
4908 * nsterm.h (ns_select): Adjust prototype.
4910 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
4911 us-resolution time stamps.
4912 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
4914 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
4916 * lisp.h (time_overflow): New decl.
4917 (wait_reading_process_output): First arg is now intmax_t, not int,
4918 to accommodate larger waits.
4920 * process.h (struct Lisp_Process.read_output_delay):
4921 Now counts nanoseconds, not microseconds.
4922 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
4924 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
4925 (wait_reading_process_output):
4926 Port to ns-resolution time stamps.
4927 (Faccept_process_output, wait_reading_process_output):
4928 Check for time stamp overflow. Do not assume time_t is signed.
4929 (select_wrapper): Remove; we now use pselect.
4930 (Fprocess_attributes): Now generates ns-resolution time stamps.
4932 * sysdep.c: Include utimens.h. Don't include utime.h
4933 or worry about struct utimbuf; gnulib does that for us now.
4934 (gettimeofday): Remove; gnulib provides a substitute.
4935 (make_timeval): New function.
4936 (set_file_times): Now sets ns-resolution time stamps.
4937 New arg FD; all uses changed.
4938 (time_from_jiffies, ltime_from_jiffies, get_up_time)
4939 (system_process_attributes):
4940 Now returns ns-resolution time stamp. All uses changed.
4941 Check for time stamp overflow.
4943 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
4944 provides a substitute now.
4946 * systime.h: Include timespec.h rather than sys/time.h and time.h,
4947 since it guarantees struct timespec.
4948 (EMACS_TIME): Now struct timespec, so that we can support
4949 ns-resolution time stamps.
4950 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4951 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4952 (EMACS_USECS): Remove.
4953 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4954 so multiply the arg by 1000 before storing it.
4955 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
4957 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
4958 Port to ns-resolution time stamps.
4959 (EMACS_TIME_NEG_P): Remove; replaced by....
4960 (EMACS_TIME_SIGN): New macro.
4961 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
4962 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

4964 (make_timeval, make_lisp_time, decode_time_components): New decls.
4965 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
4966 that it mishandled time_t overflow. You can't compare by subtracting!
4967 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
4968 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
4970 * term.c: Include <sys/time.h>.
4971 (timeval_to_Time): New function, for proper overflow wraparound.
4972 (term_mouse_position, term_mouse_click): Use it.
4974 * undo.c (record_first_change): Support higher-resolution time stamps
4976 (Fprimitive_undo): Use them when restoring time stamps.
4978 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
4979 (w32_get_internal_run_time):
4980 Port to higher-resolution Emacs time stamps.
4981 (ltime): Now accepts single 64-bit integer, as that's more convenient
4984 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
4986 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,

5060 gets killed during executing of this function (Bug#11665).

5093 * coding.c (produce_chars): Use ptrdiff_t, not int.
5095 * xterm.c (x_draw_underwave): Check for integer overflow.
5096 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5282 as the union type is for debugging, not for production.
5283 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
5284 Use an inline function on all platforms when using the union type,
5285 since this is simpler and 'static inline' can be used portably

5400 Block-based vector allocation of small vectors.

5429 * doprnt.c (doprnt): Truncate multibyte char correctly.
5430 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5431 would mishandle a string argument "Xc" if X was a multibyte
5432 character of length 2: it would truncate after X's first byte
5433 rather than including all of X.

5463 (note_mode_line_or_margin_highlight): If there is no help echo,
5464 use mode-line-default-help-echo. Handle the case where the mouse
5465 position is past the end of the mode line string.
5467 * buffer.c (buffer_local_value_1): New function, split from
5468 Fbuffer_local_value; can return Qunbound.
5469 (Fbuffer_local_value): Use it.
5470 (Vmode_line_format): Docstring tweaks.
5472 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

5476 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
5478 * keyboard.c: Export real-this-command to Elisp.
5479 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5480 and DEFVAR it. Update all users.
5482 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5484 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5486 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5487 Convert pctcpu and pctmem to Lisp float properly.
5488 Let the compiler fold better, as 100.0/0x8000 is exact.
5490 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5492 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5495 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5497 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5499 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5501 For a 'struct window', replace some Lisp_Object fields to
5502 bitfields where appropriate, remove unused fields.
5503 * window.h (struct window): Remove unused 'last_mark_x' and
5504 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5505 change it's type from Lisp_Object to bitfield.
5506 Change type of 'force_start', 'optional_new_start',
5507 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5508 fields from Lisp_Object to bitfield. Adjust users accordingly.
5510 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5512 Pacify gcc -Wdouble-precision when using Xaw.
5513 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5514 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5515 Use 'float' consistently, rather than 'float' in most places
5516 and 'double' in a couple of places.
5518 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5520 * xdisp.c (handle_stop): Detect whether we have overlay strings
5521 loaded by testing it->current.overlay_string_index to be
5522 non-negative, instead of checking whether n_overlay_strings is
5523 positive. (Bug#11587)
5525 2012-05-31 Chong Yidong <cyd@gnu.org>
5527 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5529 * doc.c (Fsubstitute_command_keys): Doc fix.
5531 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5533 * search.c (search_buffer): Remove calls to
5534 r_alloc_inhibit_buffer_relocation, as it is now called by
5535 maybe_unify_char, which was the cause of relocation of buffer text
5538 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5540 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5541 for the duration of call to load_charset, to avoid problems with
5542 callers of maybe_unify_char that access buffer text through C
5545 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5546 decrement the inhibition flag, instead of just setting or
5549 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5551 Remove obsolete '#define static' cruft.
5552 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5553 This #undef was "temporary" in 2000; it is no longer needed
5554 now that '#define static' has gone away.
5555 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5556 (gray_bitmap_bits): Remove; no longer needed.
5557 All uses replaced with definiens.
5558 * xterm.c: Include "bitmaps/gray.xbm".
5560 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5562 Clean up __executable_start, monstartup when --enable-profiling.
5563 The following changes affect the code only when profiling.
5564 * dispnew.c (__executable_start): Rename from safe_bcopy.
5565 Define only on platforms that need it.
5566 * emacs.c: Include <sys/gmon.h> when profiling.
5567 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5568 (__executable_start): Remove decl, since lisp.h does it now.
5569 (safe_bcopy): Remove decl; no longer has that name.
5570 (main): Coalesce #if into single bit of code, for simplicity.
5571 Cast pointers to uintptr_t, since standard libraries want integers
5573 * lisp.h (__executable_start): New decl.
5575 2012-05-31 Glenn Morris <rgm@gnu.org>
5577 * image.c (Fimagemagick_types): Doc fix.
5579 2012-05-30 Jim Meyering <meyering@redhat.com>
5581 * callproc.c (Fcall_process_region): Include directory component
5582 in mkstemp error message (Bug#11586).
5584 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5586 * alloc.c, lisp.h (make_pure_vector): Now static.
5588 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

5594 (Qdefun): Move from eval.c.
5595 * lisp.h (Qdefun): Remove.
5596 * lread.c (read1): Tiny simplification.
5598 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
5600 Do not create empty overlays with the evaporate property (Bug#9642).
5601 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
5602 Bug#9642, but explicitly check that the buffer the overlay would
5603 be moved to is live and rearrange lines to make sure that errors
5604 will not put the overlay in an inconsistent state.
5605 (Fdelete_overlay): Cosmetics.
5607 2012-05-28 Eli Zaretskii <eliz@gnu.org>
5609 * w32term.c (my_bring_window_to_top): New function.
5610 (x_raise_frame): Use handle returned by DeferWindowPos, which
5611 could be different from the original one.
5612 Call my_bring_window_to_top instead of my_set_foreground_window.
5615 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
5616 by calling BringWindowToTop.
5618 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
5619 (WM_EMACS_END): Increase by one.
5621 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
5623 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
5624 This avoids undefined behavior that might cause the eassert
5625 to not catch an out-of-range value.
5627 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
5629 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
5630 Update dependencies.
5632 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5634 * bidi.c (bidi_mirror_char): Fix last change.
5636 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
5638 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
5639 when referring to sectname field in printf format.
5641 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
5643 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
5644 Only r_alloc_inhibit_buffer_relocation needed to be added;
5645 the others were already declared.
5647 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
5648 before checking whether it's out of range. Put the check inside
5650 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
5652 2012-05-27 Ken Brown <kbrown@cornell.edu>
5654 * callproc.c (Fcall_process): Restore a line that was accidentally
5655 commented out in the 2011-02-13 change (bug#11547).
5657 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5659 * lisp.h [REL_ALLOC]: Add prototypes for external functions
5660 defined on ralloc.c.
5662 * buffer.c [REL_ALLOC]: Remove prototypes of
5663 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
5664 they are now on lisp.h.
5666 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
5668 * search.c (search_buffer): Use it to inhibit relocation of buffer
5669 text while re_search_2 is doing its job, because re_search_2 is
5670 passed C pointers to buffer text. (Bug#11519)
5672 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
5675 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
5676 state after an additional call to move_it_in_display_line_to, keep
5677 the values of it->max_ascent and it->max_descent found for the
5679 (pos_visible_p): Revert the comparison against bottom_y to what it
5680 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
5683 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5685 Fix coding-related core dumps with gcc -ftrapv.
5686 The code was computing A - B, where A and B are pointers, and B is
5687 random garbage. This can lead to core dumps on platforms that
5688 have special pointer registers, and it also leads to core dumps on
5689 x86-64 when compiled with gcc -ftrapv. The fix is to compute
5690 A - B only when B is initialized properly.
5691 * coding.c (coding_set_source, coding_set_destination): Return void.
5692 (coding_change_source, coding_change_destinations): New functions,
5693 with the old behaviors of coding_set_source and coding_set_destination.
5694 All callers that need an offset changed to use these new functions.
5696 2012-05-26 Glenn Morris <rgm@gnu.org>
5698 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
5700 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5702 Extend mouse support on W32 text-mode console.
5703 * xdisp.c (draw_row_with_mouse_face):
5704 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
5706 * w32console.c: Include window.h.
5707 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
5709 (initialize_w32_display): Initialize mouse-highlight data.
5711 * w32inevt.c: Include termchar.h and window.h.
5712 (do_mouse_event): Support mouse-autoselect-window. When the mouse
5713 moves, call note_mouse_highlight. If help_echo changed, call
5714 gen_help_event to produce help-echo message in the echo area.
5715 Call clear_mouse_face if mouse_face_hidden is set in the mouse
5718 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5720 * lread.c (read1): Simplify slightly to avoid an overflow warning
5721 with GCC 4.7.0 on x86-64.
5723 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5725 * bidi.c (bidi_mirror_char): Revert last change: an int is
5726 definitely wide enough here.
5728 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
5730 Fix integer width and related bugs (Bug#9874).
5731 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
5732 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
5733 (string_bytes, check_sblock, allocate_string_data):
5734 (compact_small_strings, Fmake_bool_vector, make_string)
5735 (make_unibyte_string, make_multibyte_string)
5736 (make_string_from_bytes, make_specified_string)
5737 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
5738 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
5740 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5741 (allocate_pseudovector):
5742 Use int, not EMACS_INT, where int is wide enough.
5743 (inhibit_garbage_collection, Fgarbage_collect):
5744 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5745 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
5746 int might not be wide enough.
5747 (bidi_cache_search, bidi_cache_find, bidi_init_it)
5748 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5749 (bidi_at_paragraph_end, bidi_find_paragraph_start)
5750 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
5751 (bidi_level_of_next_char, bidi_move_to_visually_next):
5752 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5753 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
5754 (Fkill_buffer, Fset_buffer_major_mode)
5755 (advance_to_char_boundary, Fbuffer_swap_text)
5756 (Fset_buffer_multibyte, overlays_at, overlays_in)
5757 (overlay_touches_p, struct sortvec, record_overlay_string)
5758 (overlay_strings, recenter_overlay_lists)
5759 (adjust_overlays_for_insert, adjust_overlays_for_delete)
5760 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
5761 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
5762 (Foverlay_recenter, last_overlay_modification_hooks_used)
5763 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
5764 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5765 (validate_region): Omit unnecessary test for b <= e,
5766 since that's guaranteed by the previous test.
5767 (adjust_overlays_for_delete): Avoid pos + length overflow.
5768 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
5769 (report_overlay_modification):
5770 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5771 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
5772 Omit pointer cast, which isn't needed anyway, and doesn't work
5773 after the EMACS_INT -> ptrdiff_t change.
5774 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
5775 * buffer.h: Adjust decls to match defn changes elsewhere.
5776 (struct buffer_text, struct buffer):
5777 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5778 Use EMACS_INT, not int, where int might not be wide enough.
5779 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
5780 not int, to avoid needless 32-bit limit on 64-bit hosts.
5781 (exec_byte_code): Use tighter memory-full test, one that checks
5782 for alloca overflow. Don't compute the address of the object just
5783 before an array, as that's not portable. Use EMACS_INT, not
5784 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
5785 * callint.c (Fcall_interactively):
5786 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5787 * callproc.c (call_process_kill, Fcall_process):
5788 Don't assume pid_t fits into an Emacs fixnum.
5789 (call_process_cleanup, Fcall_process, child_setup):
5790 Don't assume pid_t fits into int.
5791 (call_process_cleanup, Fcall_process, delete_temp_file)
5792 (Fcall_process_region):
5793 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5794 (Fcall_process): Simplify handling of volatile integers.
5795 Use int, not EMACS_INT, where int will do.
5796 * casefiddle.c (casify_object, casify_region, operate_on_word)
5797 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
5798 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5799 (casify_object): Avoid integer overflow when overallocating buffer.
5800 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
5801 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
5802 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
5803 * category.h (CATEGORYP): Don't assume arg is nonnegative.
5804 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
5805 integers are now checked earlier. All uses replaced with XINT.
5807 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5808 For CCL_MapSingle, check that content and value are in int range.
5809 (ccl_driver, Fregister_code_conversion_map):
5810 Check that Vcode_version_map_vector is a vector.
5811 (resolve_symbol_ccl_program): Check that vector header is in range.
5812 Always copy the vector, so that we can check its contents reliably
5813 now rather than having to recheck each instruction as it's being
5814 executed. Check that vector words fit in 'int'.
5815 (ccl_get_compiled_code, Fregister_ccl_program)
5816 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
5817 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
5818 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
5819 contents are in range.
5820 (Fccl_execute_on_string): Check that status is in range.
5821 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
5822 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
5823 Accept and return EMACS_INT, not int, because callers can pass values
5825 (c_string_width, strwidth, lisp_string_width, chars_in_text)
5826 (multibyte_chars_in_text, parse_str_as_multibyte)
5827 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
5828 (str_as_unibyte, str_to_unibyte, string_count_byte8)
5829 (string_escape_byte8, Fget_byte):
5830 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5831 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
5832 avoid mishandling large integers.
5833 * character.h: Adjust decls to match defn changes elsewhere.
5834 * charset.c (load_charset_map_from_file, find_charsets_in_text)
5835 (Ffind_charset_region):
5836 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5837 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
5838 (load_charset_map_from_vector, Fdefine_charset_internal):
5839 Don't assume fixnum fits in int.
5840 (load_charset_map_from_vector, Fmap_charset_chars):
5841 Remove now-unnecessary CHECK_NATNUMs.
5842 (Fdefine_charset_internal): Check ranges here, more carefully.
5843 Don't rely on undefined behavior with signed left shift overflow.
5844 Don't assume unsigned int fits into fixnum, or that fixnum fits
5845 into unsigned int. Don't require max_code to be a valid fixnum;
5846 that's not true for gb10830 4-byte on a 32-bit host. Allow
5847 invalid_code to be a cons, for the same reason. Require code_offset
5848 to be a character. Avoid int overflow if max_char is close
5850 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
5851 this is intended anyway and avoids some undefined behavior.
5852 (load_charset_map): Pass unsigned, not int, as 2nd arg of
5853 INDEX_TO_CODE_POINT, as that's what it expects.
5854 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
5855 * charset.h (DECODE_CHAR): Return int, not unsigned;
5856 this is what was intended anyway, and it avoids undefined behavior.
5857 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
5858 integer-overflow issues.
5859 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
5860 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
5861 where the argument is EMACS_INT, and this behavior is not intended.
5862 * chartab.c (Fmake_char_table, Fset_char_table_range)
5863 (uniprop_get_decoder, uniprop_get_encoder):
5864 Don't assume fixnum fits in int.
5865 * cmds.c (move_point): New function, that does the gist of
5866 Fforward_char and Fbackward_char, but does so while checking
5867 for integer overflow more accurately.
5868 (Fforward_char, Fbackward_char): Use it.
5869 (Fforward_line, Fend_of_line, internal_self_insert)
5870 (internal_self_insert):
5871 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5872 Fix a FIXME, by checking for integer overflow when calculating
5873 target_clm and actual_clm.
5874 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
5875 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)
5876 (ASSURE_DESTINATION, coding_alloc_by_realloc)

6597 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
6598 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
6599 * xterm.c (input_signal_count): Assume volatile works.
6601 2012-05-21 Ken Brown <kbrown@cornell.edu>
6603 * xgselect.c (xg_select): Fix first argument in call to 'select'
6606 2012-05-20 Ken Brown <kbrown@cornell.edu>
6608 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
6609 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
6611 2012-05-19 Ken Brown <kbrown@cornell.edu>
6613 * xfns.c (x_in_use): Remove `static' qualifier.
6614 * xterm.h (x_in_use): Declare.
6615 * xgselect.c: Include xterm.h.
6616 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
6617 and `display_arg' (bug#9754).
6619 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
6621 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
6623 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
6624 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
6626 2012-05-18 Eli Zaretskii <eliz@gnu.org>
6628 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
6630 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
6631 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
6633 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
6634 reference to image_cache->refcount.
6635 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
6637 2012-05-17 Juri Linkov <juri@jurta.org>
6639 * search.c (Fword_search_regexp, Fword_search_backward)
6640 (Fword_search_forward, Fword_search_backward_lax)
6641 (Fword_search_forward_lax): Move functions to isearch.el
6642 (bug#10145, bug#11381).
6644 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
6646 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
6648 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
6650 * lread.c (init_obarray): Declare Qt and Qnil as special.
6652 2012-05-14 Glenn Morris <rgm@gnu.org>
6654 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
6655 Put "libexec" before "bin", for the sake of init_callproc_1.
6657 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6659 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
6661 * unexaix.c: Port to more-recent AIX compilers.
6662 (report_error, report_error_1, make_hdr, copy_sym)
6663 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
6664 Make arguments const char *, not char *, to avoid violations of C
6665 standard and to fix some AIX warnings reported by Gilles Pion.
6667 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6669 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
6670 already have overlays loaded.
6671 (handle_single_display_spec): Before returning without displaying
6672 fringe bitmap, synchronize the bidi iterator with the main display
6673 iterator, by calling iterate_out_of_display_property.
6674 (iterate_out_of_display_property): Detect buffer iteration by
6675 testing that it->string is a Lisp string.
6676 (get_next_display_element): When the current object is exhausted,
6677 and there's something on it->stack, call set_iterator_to_next to
6678 proceed with what's on the stack, instead of returning zero.
6679 (set_iterator_to_next): If called at the end of a Lisp string,
6680 proceed to consider_string_end without incrementing string
6681 position. Don't increment display vector index past the end of
6682 the display vector. (Bug#11417)
6683 (pos_visible_p): Don't report a position visible when move_it_to
6684 stopped at the last line of window, which happens to be scanned
6685 backwards by the bidi iteration. (Bug#11464)
6687 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6689 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
6690 and right-margin display specs even if the spec is invalid or we
6691 are on a TTY, and thus unable to display on the fringes.
6692 That's because the text with the property will not be displayed anyway,
6693 so we need to signal to the caller that this is a "replacing"
6694 display spec. This fixes display when the spec is invalid or we
6697 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6699 * unexaix.c (make_hdr): Fix typo in prototype.
6700 This bug broke the build on AIX. Problem reported by Gilles Pion.
6702 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
6704 * keyboard.c (kbd_buffer_get_event): Read special events also in
6705 batch mode. (Bug#11415)
6707 2012-05-12 Glenn Morris <rgm@gnu.org>
6709 * ns.mk: Update for ns_appbindir no longer having trailing "/".
6711 2012-05-12 Eli Zaretskii <eliz@gnu.org>
6713 * lisp.mk (lisp): Add newcomment.elc.
6715 2012-05-12 Glenn Morris <rgm@gnu.org>
6717 * Makefile.in (MKDIR_P): New, set by configure.
6718 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
6720 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
6722 Remove unused function hourglass_started.
6723 * dispextern.h (hourglass_started):
6724 * w32fns.c (hourglass_started):
6725 * xdisp.c (hourglass_started): Remove.
6727 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
6729 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
6730 Update dependencies.
6732 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
6734 * xgselect.c (xg_select): Put maxfds+1 into a var.
6735 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
6737 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
6739 2012-05-10 Dave Abrahams <dave@boostpro.com>
6741 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
6742 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
6744 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
6746 * dbusbind.c (xd_registered_buses): New internal Lisp object.
6747 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
6748 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
6749 Initialize xd_registered_buses.
6751 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
6753 Untag more efficiently if USE_LSB_TAG.
6754 This is based on a proposal by YAMAMOTO Mitsuharu in
6755 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
6756 For an admittedly artificial (nth 8000 longlist) benchmark on
6757 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
6758 Emacs's overall text size by 1%.
6759 * lisp.h (XUNTAG): New macro.
6760 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
6761 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
6762 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
6763 * eval.c (Fautoload):
6764 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
6765 * frame.h (XFRAME): Use XUNTAG.
6767 Port recent dbusbind.c changes to 32-bit --with-wide-int.
6768 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
6769 Remove unportable assumptions about print widths of types like
6771 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
6772 intptr_t when converting between pointer and integer, to avoid GCC
6773 warnings about wrong width.
6775 2012-05-09 Eli Zaretskii <eliz@gnu.org>
6777 * w32proc.c (new_child): Force Windows to reserve only 64KB of
6778 stack for each reader_thread, instead of defaulting to 8MB
6779 determined by the linker. This avoids failures in creating
6780 subprocesses on Windows 7, see the discussion in this thread:
6781 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
6783 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
6785 Fix up display of the *Minibuf-0* buffer in the mini window.
6786 * keyboard.c (read_char): Don't clear the echo area if there's no
6788 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
6789 contents of *Minibuf-0*) if there's no message displayed in its stead.
6791 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
6793 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
6796 2012-05-06 Chong Yidong <cyd@gnu.org>
6798 * lisp.mk (lisp): Update.
6800 2012-05-05 Jim Meyering <meyering@redhat.com>
6802 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
6804 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
6806 * data.c (PUT_ERROR): New macro.
6807 (syms_of_data): Use it. Add new error type `user-error'.
6808 * undo.c (user_error): New function.
6809 (Fprimitive_undo): Use it.
6810 * print.c (print_error_message): Adjust print style for `user-error'.
6811 * keyboard.c (user_error): New function.
6812 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
6814 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
6816 Do not limit current-time-string to years 1000..9999.
6817 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
6818 (Fcurrent_time_string): Support any year that is supported by the
6819 underlying localtime representation. Don't use asctime, as it
6820 has undefined behavior for years outside the range -999..9999.
6822 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
6824 Fix race conditions involving setenv, gmtime, localtime, asctime.
6825 Without this fix, interrupts could mess up code that uses these
6826 nonreentrant functions, since setting TZ invalidates existing
6827 tm_zone or tzname values, and since most of these functions return
6828 pointers to static storage.
6829 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
6830 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
6831 Grow the critical sections to include not just invoking
6832 localtime/gmtime, but also accessing these functions' results
6833 including their tm_zone values if any, and any related TZ setting.
6834 (format_time_string): Last arg is now struct tm *, not struct tm **,
6835 so that the struct tm is saved in the critical section.
6836 All callers changed. Simplify allocation of initial buffer, partly
6837 motivated by the fact that memory allocation needs to be outside
6838 the critical section.
6840 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
6842 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
6843 with RESET_INTERVAL.
6845 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
6846 Remove duplicated buffer name initialization.
6848 2012-05-02 Jim Meyering <jim@meyering.net>
6850 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
6852 * xfns.c (x_window): Use xstrdup (Bug#11375).
6854 2012-05-02 Eli Zaretskii <eliz@gnu.org>
6856 * xdisp.c (pos_visible_p): If already at a newline from the
6857 display string before the 'while' loop, don't walk back the glyphs
6858 from it3.glyph_row. Solves assertion violation when the display
6859 string begins with a newline (egg.el). (Bug#11367)
6861 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
6863 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
6866 2012-05-01 Glenn Morris <rgm@gnu.org>
6868 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
6869 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
6870 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
6871 All were removed before 23.1.
6873 * dispnew.c: Remove HAVE_LIBNCURSES test;
6874 it is always true on relevant platforms.
6876 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
6877 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
6879 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
6881 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
6883 * .gdbinit (xpr): Remove checks for no longer existing misc types.
6884 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
6887 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
6889 Do not avoid creating empty evaporating overlays (Bug#9642).
6890 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
6891 That is, do not delete an evaporating overlay if it becomes
6892 empty after its bounds are adjusted to fit within its buffer.
6893 This fix caused other problems, and I'm reverting it until we get
6894 to the bottom of them.
6896 2012-04-27 Chong Yidong <cyd@gnu.org>
6898 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
6900 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6902 * xdisp.c (pos_visible_p): If the window start position is beyond
6903 ZV, start the display from buffer beginning. Prevents assertion
6904 violation in init_iterator when the minibuffer window is scrolled
6907 * window.c (window_scroll_pixel_based): Likewise.
6909 2012-04-27 Chong Yidong <cyd@gnu.org>
6911 * keymap.c (where_is_internal): Doc fix (Bug#10872).
6913 2012-04-27 Glenn Morris <rgm@gnu.org>
6915 * fileio.c (Fcopy_file, Fset_file_selinux_context):
6916 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
6918 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6920 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
6921 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
6923 2012-04-26 Eli Zaretskii <eliz@gnu.org>
6925 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
6926 display element, check also the underlying string or buffer
6927 character. (Bug#11341)
6929 * w32menu.c: Include w32heap.h.
6930 (add_menu_item): If the call to AppendMenuW (via
6931 unicode_append_menu) fails, disable Unicode menus only if we are
6932 running on Windows 9X/Me.
6934 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6936 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6937 (xgetint): Add missing shift for LSB tags.
6939 2012-04-24 Martin Rudalics <rudalics@gmx.at>
6941 * keyboard.c (read_char): Don't wipe echo area for select window
6942 events: These might get delayed via `mouse-autoselect-window'
6945 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
6947 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
6948 manipulation of :loaded-from data.
6950 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6952 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6953 now a cons (bug#11311).
6955 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
6957 Do not create empty overlays with the evaporate property (Bug#9642).
6958 * buffer.c (Fmove_overlay): Delete an evaporating overlay
6959 if it becomes empty after its bounds are adjusted to fit within
6960 its buffer. Without this fix, in a nonempty buffer (let ((o
6961 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
6962 yields an empty overlay that has the evaporate property, which is
6963 not supposed to happen.
6965 Fix minor GTK3 problems found by static checking.
6966 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
6967 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6968 (struct _EmacsFixedClass, emacs_fixed_get_type):
6969 Move decls here from emacsgtkfixed.h, since they needn't be public.

6971 (emacs_fixed_class_init): Omit unused local.
6972 (emacs_fixed_child_type): Remove; unused.

6974 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6975 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
6976 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
6977 (EMACS_FIXED_GET_CLASS): Remove; unused.
6978 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
6980 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
6981 Problem reported by Juanma Barranquero for Windows -Wunused-function.
6983 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6985 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
6986 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
6987 (__malloc_size_t, __malloc_ptrdiff_t):
6988 Remove. All uses removed, replaced by the definiens if needed,
6989 since we can assume C89 or better now.
6990 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
6991 (protect_malloc_state, align, get_contiguous_space)
6992 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
6993 (malloc_atfork_handler_child, malloc_enable_thread)

6996 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
6997 (special_realloc, _realloc_internal_nolock, _realloc_internal)
6998 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
6999 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7000 Define using prototypes, not old style.
7001 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7002 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7003 (align): Don't assume that signed integer overflow wraps around.
7004 Omit unused local var.
7005 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7006 (_free_internal_nolock, memalign, mallochook, reallochook):
7007 Omit no-longer-needed casts.
7008 (valloc): Use getpagesize, not __getpagesize.
7009 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7010 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7012 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7014 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7016 Move functions from C to Lisp. Make non-blocking method calls
7017 the default. Implement further D-Bus standard interfaces.
7019 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7020 (QCdbus_request_name_allow_replacement)
7021 (QCdbus_request_name_replace_existing)
7022 (QCdbus_request_name_do_not_queue)

7048 (Fdbus_send_signal, Fdbus_register_service)
7049 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

7063 Do not assume ptrdiff_t is the same width as 'int'.
7065 * alloc.c: Handle unusual debugging option combinations.
7066 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7067 since the two debugging options are incompatible.
7068 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7070 (mem_init, mem_insert, mem_insert_fixup):
7071 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7101 * print.c (print_preprocess): Only check print_depth if print-circle
7103 (print_object): Check for cycles even when print-circle is nil and
7104 print-gensym is t, but only check print_depth if print-circle is nil.
7106 2012-04-20 Chong Yidong <cyd@gnu.org>
7108 * process.c (wait_reading_process_output): If EIO occurs on a pty,
7109 set the status to "failed" and ensure that sentinel is run.

7124 farther than the first row after the header line, if any.
7125 Don't consider the header-line row as "partially visible", even if
7126 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
7128 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7163 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
7164 New extern decls, to avoid calling undeclared functions.
7165 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7166 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7167 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

7189 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
7191 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

7206 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
7207 * s/netbsd.h, s/sol2-6.h:
7208 Remove definition of GC_MARK_STACK, since the default now works.
7209 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7210 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7211 no longer the default.
7212 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7214 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
7216 * lread.c (lisp_file_lexically_bound_p):

7226 * nsterm.m (constrainFrameRect): Always constrain when there is only
7227 one screen (Bug#10962).

7237 2012-04-11 Daniel Colascione <dancol@dancol.org>
7239 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7240 against is gone. It's better to use vfork now so that when Cygwin
7241 gains a new, working vfork, we use it automatically (bug#10398).
7243 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7264 being loaded (bug#10424).
7266 2012-04-09 Glenn Morris <rgm@gnu.org>
7268 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7269 not just in the obarray, before snarfing them. (Bug#11036)
7271 * Makefile.in ($(leimdir)/leim-list.el):

7296 * minibuf.c (Fread_variable): Callers changed.
7298 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7300 * xdisp.c (set_cursor_from_row): If the display string appears in
7301 the buffer at position that is closer to point than the position
7302 after the display string, display the cursor on the first glyph of
7303 the display string. Fixes cursor display when a 'display' text
7304 property immediately follows invisible text. (Bug#11094)
7306 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7308 composite.c: use 'double' consistently
7309 * composite.c (get_composition_id): Use 'double' consistently
7310 instead of converting 'float' to 'double' and vice versa; this is
7311 easier to understand and avoids a GCC warning.
7313 2012-04-09 Glenn Morris <rgm@gnu.org>
7315 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7316 preparation for dumping it with emacs. (Bug#4789)

7358 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7359 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7360 [!WINDOWSNT]: New macros.
7361 (init_libxml2_functions, libxml2_loaded_p): New functions.
7362 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7363 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7364 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7365 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7367 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7368 Call init_libxml2_functions before calling libxml2 functions.
7369 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7371 * emacs.c: Don't include libxml/parser.h.

7373 xmlCleanupParser directly.
7375 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7377 2012-04-07 Eli Zaretskii <eliz@gnu.org>

7385 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7386 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7387 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7388 macros related to unification of CJK characters. For the details,
7389 see the discussion following the message here:
7390 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7392 2012-04-04 Chong Yidong <cyd@gnu.org>

7406 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7408 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7409 position we get to after a call to move_it_to fails the
7410 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7411 only if we wind up in a string from display property. (Bug#11063)
7413 * window.c (Fdelete_other_windows_internal): Invalidate the row
7414 and column information about mouse highlight, so that redisplay
7415 restores it after reallocating the glyph matrices. (Bug#7464)
7417 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7418 string comes from a `display' text property, use the buffer
7419 position of that property as if we actually saw that position in
7421 (move_it_by_lines): Remove the assertion that
7422 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7423 violated when there's a before-string at the beginning of a line.
7426 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7428 * xdisp.c (append_space_for_newline): If the default face was
7429 remapped, use the remapped face for the appended newline.

7431 extending the face to the end of the line.
7432 (display_line): Call extend_face_to_end_of_line when the default
7433 face was remapped. (Bug#11068)

7468 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7470 * s/ms-w32.h (tzname): Include time.h before redirecting to

7481 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7483 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7484 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7485 when fetching a multibyte character consumes more bytes than
7486 CHAR_BYTES returns, due to unification of CJK characters in
7487 string_char. (Bug#11073)
7489 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7491 * process.c (wait_reading_process_output): Handle pty disconnect

7525 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7526 that is not from display property, accept the row as a "cursor
7527 row" if one of the string's character has a non-nil `cursor'
7528 property. Fixes cursor positioning when there are newlines in
7529 overlay strings, e.g. in icomplete.el. (Bug#11035)
7531 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

7562 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7565 2012-03-03 Glenn Morris <rgm@gnu.org>
7567 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

7575 (redisplay_window): Pass to move_it_vertically the margin in
7576 pixels, not in screen lines.
7578 2012-03-02 Glenn Morris <rgm@gnu.org>
7580 * buffer.c (buffer-list-update-hook): Doc fix.
7582 2012-02-29 Eli Zaretskii <eliz@gnu.org>

7585 push_it before setting up the iterator for the first overlay
7586 string, even if we have an empty string loaded.
7587 (next_overlay_string): If there's an empty string on the iterator
7588 stack, pop the stack. (Bug#10903)
7590 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
7592 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
7593 Suggested by Stefan Monnier in
7594 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
7595 * alloc.c (widen_to_Lisp_Object): New static function.
7596 (mark_memory): Also mark Lisp_Objects by fetching pointer words
7597 and widening them to Lisp_Objects. This would work even if
7598 USE_LSB_TAG is defined and wide integers are used, which might
7599 happen in a future version of Emacs.
7601 2012-02-25 Chong Yidong <cyd@gnu.org>
7603 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

7607 (x_clipboard_manager_save_all): Print an informative message
7608 before saving to clipboard manager.
7610 2012-02-24 Chong Yidong <cyd@gnu.org>
7612 * keyboard.c (process_special_events): Handle all X selection

7615 2012-02-23 Chong Yidong <cyd@gnu.org>
7617 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
7618 call when setting menu-bar-lines and tool-bar-lines parameters.
7619 (unwind_create_frame_1): New helper function.
7621 * window.c (inhibit_window_configuration_change_hook): New var.
7622 (run_window_configuration_change_hook): Obey it.
7623 (syms_of_window): Initialize it.
7625 2012-02-22 Chong Yidong <cyd@gnu.org>

7640 when computing $valmask.
7642 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
7643 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
7644 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
7645 It's useless in that case, and it can cause problems on hosts
7646 that allocate halves of EMACS_INT values separately.
7647 Reported by Dan Horák. Diagnosed by Andreas Schwab in
7648 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
7649 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
7650 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
7651 it avoids undefined behavior on hosts where shifting right by more
7652 than the word width has undefined behavior.
7654 2012-02-19 Chong Yidong <cyd@gnu.org>
7656 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
7657 (Funhandled_file_name_directory, Ffile_name_as_directory)

7676 2012-02-15 Chong Yidong <cyd@gnu.org>
7678 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
7679 marked as special. Also, starting docstrings with * is obsolete.
7681 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

7696 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
7697 as that creates a dangerous corner case.
7699 * window.c (Fdelete_window_internal): Invalidate the mouse
7700 highlight (Bug#9904).
7702 2012-02-12 Glenn Morris <rgm@gnu.org>

7707 * nsselect.m (Fx_own_selection_internal)
7708 (Fx_disown_selection_internal, Fx_selection_exists_p)
7709 (Fx_selection_owner_p, Fx_get_selection_internal):
7710 Sync docs and argument specs with the xselect.c versions.

7732 2012-02-07 Chong Yidong <cyd@gnu.org>
7734 * buffer.c (Fbuffer_local_variables)
7735 (buffer_lisp_local_variables): Handle unbound vars correctly;
7736 don't let Qunbound leak into Lisp.
7738 2012-02-07 Glenn Morris <rgm@gnu.org>
7740 * image.c (Fimagemagick_types): Doc fix.
7742 * image.c (imagemagick-render-type): Change it from a lisp object

7748 * doc.c (store_function_docstring): Avoid applying docstring of
7749 alias to base function (Bug#2603).

7775 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
7777 Handle overflow when computing char display width (Bug#9496).
7778 * character.c (char_width): Return EMACS_INT, not int.
7779 (char_width, c_string_width): Check for overflow when
7780 computing the width; this is possible now that individual
7781 characters can have unbounded width. Problem introduced
7782 by merge from Emacs 23 on 2012-01-19.
7784 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

7813 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
7814 first 2 arguments are identical. This makes inserting large
7815 output from a subprocess an order of magnitude faster on
7816 MS-Windows, where all sbrk'ed memory is always contiguous.

7922 emacs: fix an auto-save permissions race condition (Bug#10400)
7923 * fileio.c (auto_saving_dir_umask): New static var.
7924 (Fmake_directory_internal): Use it.
7925 (do_auto_save_make_dir): Set it, instead of invoking chmod after
7926 creating the directory. The old code temporarily assigns
7927 too-generous permissions to the directory.
7928 (do_auto_save_eh): Clear it.
7929 (Fdo_auto_save): Catch all errors, not just file errors, so
7930 that the var is always cleared.

7987 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
7988 property that ends at ZV, so that the bidi iteration could be

8454 behave as if the cursor position were at the window margin.
8456 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8457 and the cursor position is out of bounds, behave as if the cursor
8458 position were at the window margin. (Bug#10075)

8488 * dispnew.c (verify_row_hash): Call row_hash for computing the
8489 hash code of a row, instead of duplicating code from xdisp.c.
8491 * dispextern.h (row_hash): Add prototype.
8493 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

8684 (static_offset_intervals): Remove.
8685 (offset_intervals): Rewrite using the old contents of
8686 static_offset_intervals. The old version didn't conform to C99

8990 (bidi_resolve_explicit_1): When next_en_pos is valid for the
8991 current character, check also for next_en_type being WEAK_EN.
8992 (bidi_resolve_weak): Don't enter the expensive loop if the current
8993 position is before next_en_pos. Record the bidi type of the first
8994 non-ET, non-BN character we find, in addition to its position.
8995 (bidi_level_of_next_char): Invalidate next_en_type when
8996 next_en_pos is over-stepped.

9000 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9001 * editfns.c: Rewrite current-time-zone so that it invokes
9002 the equivalent of (format-time-string "%Z") to get the time zone name.
9003 This fixes a bug when the time zone name contains characters that
9004 need converting from the system time locale to Emacs internal format.
9005 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9006 that patch fixed format-time-string to do the conversion, but
9007 I forgot to fix current-time-zone.
9008 (format_time_string): New function, containing most of
9009 what Fformat_time_string used to contain.
9010 (Fformat_time_string): Rewrite in terms of format_time_string.
9011 This doesn't change this function's behavior.
9012 (current-time-zone): Rewrite to use format_time_string.
9013 This fixes the bug reported by Michael Schierl in
9014 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9015 Jason Rumney's 2007-06-07 change worked around this bug, but
9017 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9019 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9021 * xdisp.c (start_display): If the character at POS is displayed
9022 via a display vector, reset IT->current.dpvec_index to zero.
9023 (try_window_reusing_current_matrix): If a line ends in a display
9024 vector or the next line starts in a display vector, continue
9025 redrawing the window even though the character position of
9026 start_row was reached.
9029 2011-10-18 Chong Yidong <cyd@gnu.org>
9031 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9032 with nobreak-char-display too.
9034 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9036 Fix part 3 of bug#9771.
9037 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9038 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9039 non-neutral characters if the current character is a paragraph
9040 separator (a.k.a. Newline). This avoids running the same
9041 expensive loop twice, once when we consume the preceding newline
9042 and the other time when the line actually needs to be displayed.
9043 Avoid the loop when we see neutrals on the base embedding level
9044 following a character whose directionality is the same as the
9045 paragraph's. This avoids running the expensive loop when a line
9046 ends in a long sequence of neutrals, like control characters.
9047 Add assertion against STRONG_AL type. Slightly rearrange code
9048 that determines the type of a neutral given the first non-neutral
9050 (bidi_level_of_next_char): Set next_en_pos to zero when
9051 invalidating its info.
9053 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9055 * xdisp.c (push_display_prop): Determine whether to record string
9056 or buffer position by IT->string, not by IT->method. Allow
9057 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9058 (move_it_vertically_backward): Don't look for character position
9059 immediately after the newline when in a continuation line.
9062 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9064 * window.c (coordinates_in_window): Rewrite and delabelize
9065 vertical border check. (Bug#5357) (Bug#9618)
9067 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9069 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9070 errors in XSetWindowBorder (bug#9310).
9072 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9074 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9075 avoid crash when xmalloc overrun checking is enabled.
9077 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9079 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9080 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9081 cursor motion with <left> and <right> arrow keys.
9083 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9084 some callers set that themselves.
9086 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9088 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9089 display string and the previous row comes from the same string and
9090 is empty. (Bug#9739) (Bug#9738)
9092 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9094 * doc.c (get_doc_string): Encode file name (bug#9735).
9096 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9098 * bidi.c (bidi_level_of_next_char):
9099 * xdisp.c (get_visually_first_element): Remove old incorrect
9100 comments regarding the Unicode Line Separator character.
9102 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9104 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9106 * alloc.c (Fgc_status): Do not access beyond zombies array
9107 boundary if nzombies > MAX_ZOMBIES.
9108 * alloc.c (dump_zombies): Add missing format specifier.
9110 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9112 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9113 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9115 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9116 Some packages use them to denote characters with modifiers.
9118 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9120 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9121 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9122 matching a pp-number. Rename parameter var to var1.
9124 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9126 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9128 2011-10-08 Glenn Morris <rgm@gnu.org>
9130 * callint.c (Fcall_interactively): Give a more explicit error for the
9131 'c' case with a non-character input. (Bug#8479)
9133 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9135 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9137 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9138 lines that are hscrolled on the left.
9140 * dispnew.c (buffer_posn_from_coords): Account for a possible
9141 presence of header-line. (Bug#4426)
9143 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9145 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9146 Don't advertise functionality which we discourage or doesn't work.
9148 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9150 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9151 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9152 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9153 this makes Emacs dump core during garbage collection on rare
9154 occasions. sizeof is obviously inferior to offsetof here, so
9155 stick with offsetof.
9156 (GC_POINTER_ALIGNMENT): New macro.
9157 (mark_memory): Omit 3rd (offset) arg; caller changed.
9158 Don't assume EMACS_INT alignment is the same as pointer alignment.
9160 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9162 * keyboard.c (read_key_sequence_remapped): New var.
9163 (read_key_sequence): Compute remapping in the right buffer.
9164 (command_loop_1): Use read_key_sequence's remapping directly.
9166 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9168 * dired.c (file_name_completion): Don't expand file name.
9169 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9170 before checking file name handler.
9172 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9173 they've been requested explicitly (bug#9591).
9175 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9177 * keymap.c (Fsingle_key_description): Use make_specified_string
9178 instead of build_string to build string from push_key_description.
9181 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9183 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9184 This fixes a Y2038 bug on 64-bit hosts.
9185 * buffer.c (reset_buffer):
9186 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9187 (Fclear_buffer_auto_save_failure):
9188 Use 0, not -1, to represent an unset failure time, since time_t
9189 might not be signed.
9191 Remove dependency on glibc malloc internals.
9192 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9193 Move back here from lisp.h, but with their new implementations.
9194 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9195 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9196 * charset.c (charset_table_init): New static var.
9197 (syms_of_charset): Use it instead of xmalloc. This removes a
9198 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9199 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9200 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9201 Move back to alloc.c.
9202 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9203 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9205 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9207 * nsterm.m (windowDidResize): Call x_set_window_size only when
9208 ns_in_resize is true. Otherwise set pixelwidth/height and
9209 call change_frame_size (Bug#9628).
9211 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9213 Port --enable-checking=all to Fedora 14 x86-64.
9214 * charset.c (syms_of_charset): Also account for glibc malloc's
9215 internal overhead when calculating the initial malloc maximum.
9217 Port --enable-checking=all to Fedora 14 x86.
9218 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9220 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9221 (overrun_check_realloc, overrun_check_free):
9222 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9223 That way, xmalloc returns a properly-aligned pointer even if
9224 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9225 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9226 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9227 into account when calculating the initial malloc maximum.
9228 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9229 Move here from alloc.c, so that charset.c can use it too.
9230 Properly align; the old code wasn't right for common 32-bit hosts
9231 when configured with --enable-checking=all.
9232 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9233 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9235 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9237 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9240 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9242 * xdisp.c (compute_display_string_end): If there's no display
9243 string at CHARPOS, return -1.
9245 * bidi.c (bidi_fetch_char): When compute_display_string_end
9246 returns a negative value, treat the character as a normal
9247 character not covered by a display string. (Bug#9624)
9249 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9251 * lread.c (Fread_from_string): Fix typo in docstring.
9253 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9255 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9256 newline, reseat the iterator instead of bidi-iterating there one
9257 character at a time. (Bug#9610)
9258 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9259 TO_CHARPOS if the bidi iterator is at base embedding level.
9261 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9263 * lread.c (readevalloop): Use correct code for NBSP.
9264 (read1): Likewise. (Bug#9608)
9266 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9268 * dbusbind.c (Fdbus_register_signal): When service is not
9269 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9271 2011-09-25 Glenn Morris <rgm@gnu.org>
9273 * buffer.c (truncate-lines): Doc fix.
9275 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9277 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9278 (Fset_window_next_buffers): Doc fix.
9280 2011-09-24 Glenn Morris <rgm@gnu.org>
9282 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9284 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9286 Fix minor problems found by static checking.
9287 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9288 * indent.c (Fvertical_motion): Fix == vs = typo.
9290 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9292 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9293 Default value is now t. Doc fix.
9295 * indent.c (Fvertical_motion): Compute and apply the overshoot
9296 logic when moving up, not only when moving down. Fix the
9297 confusing name and values of the it_overshoot_expected variable;
9298 logic changes accordingly. (Bug#9254) (Bug#9549)
9300 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9301 CHARPOS is covered by a display string which includes newlines.
9302 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9303 is covered by a display string with embedded newlines.
9305 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9307 * dbusbind.c (Fdbus_register_signal): Add match rule to
9308 Vdbus_registered_objects_table. (Bug#9581)
9309 (Fdbus_register_method, Vdbus_registered_objects_table):
9312 2011-09-24 Jim Meyering <meyering@redhat.com>
9314 do not ignore write error for any output size
9315 The previous change was incomplete.
9316 While it makes emacs --batch detect the vast majority of stdout
9317 write failures, errors were still ignored whenever the output size is
9318 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9319 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9320 && echo FAIL: ignored write error
9321 FAIL: ignored write error
9322 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9323 && echo FAIL: ignored write error
9324 FAIL: ignored write error
9325 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9327 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

9330 non-successfully if a write error occurred on stdout. (Bug#9574)
9332 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9334 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9337 * dispextern.h (struct it): Update the comment documenting what
9340 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9342 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9343 a display string, extend search for cursor position to end of row.
9344 (find_row_edges): If the row ends in a newline from a display
9345 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9346 Handle the case of a display string with multiple newlines.
9347 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9348 non-empty line. Fixes confusing cursor motion with arrow keys at
9349 the beginning of a line that starts with whitespace.

9358 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9361 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9363 * xdisp.c (display_line): Record maximum and minimum buffer
9364 positions even if no glyphs were produced (e.g., by a zero-width
9365 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9366 buffer positions that will be removed from the glyph row because
9368 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9369 column is beyond frame width: don't subtract 1 "pixel" when
9370 computing width of the stretch.
9371 (reseat_at_next_visible_line_start): Undo the change made on
9372 2011-09-17 that saved paragraph information and restored it after
9373 the call to `reseat'. (Bug#9545)
9375 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9377 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9378 and turn window cursor on if cleared (Bug#9415).
9380 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9382 * search.c (boyer_moore): Take unibyte characters from pattern

9387 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9389 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9391 Fix minor problem found by static checking.
9392 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9393 initialized, to pacify gcc -Wuninitialized.
9395 * fileio.c: Report proper errno when syscall falls.
9396 (Finsert_file_contents): Save and restore errno,
9397 so that report_file_error outputs the correct diagnostic.
9398 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9400 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9402 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9404 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9406 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9407 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9409 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9411 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9412 about the current paragraph and restore it after the call to reseat.
9414 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9415 (bidi_find_paragraph_start): Search back for paragraph beginning
9416 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9417 (bidi_move_to_visually_next): Only trigger paragraph-related
9418 computations when the last character is a newline or at EOB, not
9419 just any NEUTRAL_B. (Bug#9470)
9421 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9422 truncated lines if point is covered by a display string. (Bug#9524)
9424 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9426 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9427 (cons_to_x_long): New function.
9428 (lisp_data_to_selection_data): Use it. Correct the test for
9429 short-versus-long data; it was negated. Break out of vector
9430 loop, for efficiency, when a long datum is discovered.
9432 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9434 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9436 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9438 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

9457 (fill_composite_glyph_string): Add comments about special meaning
9458 of TAB characters in a composition.
9460 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9462 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9463 This occurs when processing a multibyte format.
9464 Problem reported by Wolfgang Jenker.
9466 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9468 * xdisp.c (try_cursor_movement): Only check for exact match if
9469 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9471 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9473 Remove unused external symbols.
9474 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9475 * xdisp.c (calc_pixel_width_or_height): Now static.
9476 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9477 * indent.c (check_display_width):
9478 * w32term.c: Fix comment to match code.
9479 * xterm.c, xterm.h (x_catching_errors): Remove.
9481 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9483 * xselect.c: Use signed conversions more consistently (Bug#9498).
9484 (selection_data_to_lisp_data): Assume incoming selection data are
9485 signed integers, not unsigned. This is to be consistent with
9486 outgoing selection data, which was modified to use signed integers
9487 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9488 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9489 expects long, not unsigned long.
9491 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9493 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9494 computation of loop end. Reported by Johan Bockgård
9497 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9499 * frame.c (Fother_visible_frames_p): Function deleted.
9501 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9503 * indent.c (compute_motion): Process display vector front to back
9504 rather than the other way around. (Bug#2496)
9506 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9508 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9510 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9512 * minibuf.c (Fread_from_minibuffer): Doc fix.
9514 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9516 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9517 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9519 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9521 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9522 value for non-existent files.
9524 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9526 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9527 set its "size" to -1. This will set the modtime_size field of
9528 the corresponding buffer to -1, which is what
9529 verify-visited-file-modtime expects for files that do not exist.
9532 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9534 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9536 * lisp.h: ... from here. push_key_description is no longer
9537 defined in keyboard.c, so its declaration should not be in
9538 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9539 logically belongs with push_key_description.
9541 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9543 * buffer.h: Include <sys/types.h> instead of <time.h>.
9544 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9545 Problem reported by Herbert J. Skuhra.
9547 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9549 * xml.c (parse_region): Make the parsing work for
9550 non-comment-starting XML files again (bug#9144).
9552 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9554 * image.c (gif_load): Fix calculation of bottom and right corner.
9557 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9559 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9560 redisplay in small windows.
9562 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9564 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9566 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9568 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9569 Operate on live windows only.
9571 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
9573 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
9575 2011-09-07 Eli Zaretskii <eliz@gnu.org>
9577 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
9578 only under bidi iteration.
9580 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
9582 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9584 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9586 isnan: Fix porting problem to Solaris 10 with bundled gcc.
9587 Without this fix, the command to link temacs failed due to an
9588 undefined symbol __builtin_isnan. This is because
9589 /usr/include/iso/math_c99.h #defines isnan(x) to
9590 __builtin_isnan(x), but the bundled gcc, which identifies itself
9591 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
9593 * floatfns.c (isnan): #undef, and then #define to a clone of
9595 (Fisnan): Always define, since it's always available now.
9596 (syms_of_floatfns): Always define isnan at the Lisp level.
9598 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9600 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
9602 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9604 * fileio.c: Fix bugs with large file offsets (Bug#9428).
9605 The previous code assumed that file offsets (off_t values) fit in
9606 EMACS_INT variables, which is not true on typical 32-bit hosts.
9607 The code messed up by falsely reporting buffer overflow in cases
9608 such as (insert-file-contents "big" nil 1 2) into an empty buffer
9609 when "big" contains more than 2**29 bytes, even though this
9610 inserts just one byte and does not overflow the buffer.
9611 (Finsert_file_contents): Store file offsets as off_t
9612 values, not as EMACS_INT values. Check for overflow when
9613 converting between EMACS_INT and off_t. When checking for
9614 buffer overflow or for overlap, take the offsets into account.
9615 Don't use EMACS_INT for small values where int suffices.
9616 When checking for overlap, fix a typo: ZV was used where
9617 ZV_BYTE was intended.
9618 (Fwrite_region): Don't assume off_t fits into 'long'.
9619 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
9621 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
9623 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
9625 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9627 sprintf-related integer and memory overflow issues (Bug#9412).
9629 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
9630 (esprintf, exprintf, evxprintf): New functions.
9631 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
9632 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
9633 (modify_event_symbol): Do not assume that the length of
9634 name_alist_or_stem is safe to alloca and fits in int.
9635 (Fexecute_extended_command): Likewise for function name and binding.
9636 (Frecursion_depth): Wrap around reliably on integer overflow.
9637 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
9638 since some callers pass EMACS_INT values.
9639 (Fsingle_key_description): Don't crash if symbol name contains more
9640 than MAX_ALLOCA bytes.
9641 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
9642 (get_minibuffer): Arg is now EMACS_INT, not int.
9643 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
9644 (esprintf, exprintf, evxprintf): New decls.
9645 * window.h (command_loop_level, minibuf_level): Reflect API changes.
9647 * dbusbind.c (signature_cat): New function.
9648 (xd_signature, Fdbus_register_signal):
9649 Do not overrun buffer; instead, report string overflow.
9651 * dispnew.c (add_window_display_history): Don't overrun buffer.
9652 Truncate instead; this is OK since it's just a log.
9654 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
9655 even if the time zone offset is outlandishly large.
9656 Don't mishandle offset == INT_MIN.
9658 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
9659 when creating daemon; the previous buffer-overflow check was incorrect.
9661 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
9662 which has the guts of the old verror function.
9664 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
9665 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
9667 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
9668 (font_unparse_xlfd): Don't blindly alloca long strings.
9669 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
9670 fits in int, when using sprintf. Use single snprintf to count
9671 length of string rather than counting it via multiple sprintfs;
9672 that's simpler and more reliable.
9673 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
9674 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
9675 sprintf, in case result does not fit in int.
9677 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
9678 (fontset_from_font): Print it.
9680 * frame.c (tty_frame_count): Now printmax_t, not int.
9681 (make_terminal_frame, set_term_frame_name): Print it.
9682 (x_report_frame_params): In X, window IDs are unsigned long,
9683 not signed long, so print them as unsigned.
9684 (validate_x_resource_name): Check for implausibly long names,
9685 and don't assume name length fits in 'int'.
9686 (x_get_resource_string): Don't blindly alloca invocation name;
9687 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
9690 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
9691 (xg_check_special_colors, xg_set_geometry):
9692 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
9694 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
9695 Use esprintf, not sprintf, in case result does not fit in int.
9697 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9698 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
9699 it as a large positive number.
9700 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
9701 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9703 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
9704 in case result does not fit in int.
9706 * print.c (float_to_string): Detect width overflow more reliably.
9707 (print_object): Make sprintf buffer a bit bigger, to avoid potential
9708 buffer overrun. Don't assume list length fits in 'int'. Treat
9709 print length of 0 as 0, not as infinity; to be consistent with other
9710 uses of print length in this function. Don't overflow print length
9711 index. Don't assume hash table size fits in 'long', or that
9712 vectorlike size fits in 'unsigned long'.
9714 * process.c (make_process): Use printmax_t, not int, to format
9715 process-name gensyms.
9717 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
9719 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
9720 to avoid potential buffer overrun.
9722 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
9723 if X resource line is longer than 512 bytes.
9725 * xfns.c (x_window): Make sprintf buffer a bit bigger
9726 to avoid potential buffer overrun.
9728 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
9730 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
9732 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9734 Integer overflow fixes for scrolling, etc.
9735 Without these, Emacs silently mishandles large integers sometimes.
9736 For example, "C-u 4294967297 M-x recenter" was treated as if
9737 it were "C-u 1 M-x recenter" on a typical 64-bit host.
9739 * xdisp.c (try_window_id): Check Emacs fixnum range before
9740 converting to 'int'.
9742 * window.c (window_scroll_line_based, Frecenter):
9743 Check that an Emacs fixnum is in range before assigning it to 'int'.
9744 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
9745 values converted from Emacs fixnums.
9746 (Frecenter): Don't wrap around a line count if it is out of 'int'
9747 range; instead, treat it as an extreme value.
9748 (Fset_window_configuration, compare_window_configurations):
9749 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
9751 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
9752 that can exceed INT_MAX. Check that EMACS_INT value is in range
9753 before assigning it to the (possibly-narrower) index.
9754 (match_limit): Don't assume that a fixnum can fit in 'int'.
9756 * print.c (print_object): Use ptrdiff_t, not int, for index that can
9759 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
9760 (Fvertical_motion): Don't wrap around LINES values that don't fit
9761 in 'int'. Instead, treat them as extreme values. This is good
9762 enough for windows, which can't have more than INT_MAX lines anyway.
9764 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9766 * Require libxml/parser.h to avoid compilation warning.
9768 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
9770 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
9771 since this reportedly can destroy thread storage.
9773 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
9775 * syntax.c (find_defun_start): Update all cache variables if
9776 exiting early (Bug#9401).
9778 2011-08-30 Eli Zaretskii <eliz@gnu.org>
9780 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
9782 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
9783 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
9784 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
9786 * term.c (tty_append_glyph): New function.
9787 (produce_stretch_glyph): Static function and its prototype deleted.
9789 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
9792 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
9794 * image.c (parse_image_spec): Check for nonnegative, not for positive,
9795 when checking :margin (Bug#9390).
9796 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
9797 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
9798 so that the name doesn't mislead. All uses changed.
9800 2011-08-28 Johan Bockgård <bojohan@gnu.org>
9802 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
9805 2011-08-27 Eli Zaretskii <eliz@gnu.org>
9807 * xdisp.c (move_it_to): Don't bail out early when reaching
9808 position beyond to_charpos, if we are scanning backwards.
9809 (move_it_vertically_backward): When DY == 0, make sure we get to
9810 the first character in the line after the newline.
9812 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
9814 * ccl.c: Improve and simplify overflow checking (Bug#9196).
9815 (ccl_driver): Do not generate an out-of-range pointer.
9816 (Fccl_execute_on_string): Remove unnecessary check for
9817 integer overflow, noted by Stefan Monnier in
9818 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
9819 Remove a FIXME that didn't need fixing.
9820 Simplify the newly-introduced buffer reallocation code.
9822 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
9824 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
9826 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
9828 Integer and memory overflow issues (Bug#9196).
9830 * doc.c (get_doc_string): Rework so that
9831 get_doc_string_buffer_size is the actual buffer size, rather than
9832 being 1 less than the actual buffer size; this makes xpalloc more
9835 * image.c (x_allocate_bitmap_record, cache_image):
9836 * xselect.c (Fx_register_dnd_atom):
9837 Simplify previous changes by using xpalloc.
9839 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
9840 since either will do and ptrdiff_t is convenient with xpalloc.
9842 * charset.c (charset_table_size)
9843 (struct charset_sort_data.priority): Now ptrdiff_t.
9844 (charset_compare): Don't overflow if priorities differ greatly.
9845 (Fsort_charsets): Don't assume list length fits in int.
9846 Check for size-calculation overflow when allocating sort data.
9847 (syms_of_charset): Allocate an initial charset table that is
9848 just under 64 KiB, to avoid problems with glibc malloc and mmap.
9850 * cmds.c (internal_self_insert): Check for size-calculation overflow.
9852 * composite.h (struct composition.glyph_len): Now int, not unsigned.
9853 The actual value is always <= INT_MAX, and leaving it unsigned made
9854 overflow checking harder.
9856 * dispextern.h (struct glyph_matrix.rows_allocated)
9857 (struct face_cache.size): Now ptrdiff_t, for convenience in use
9858 with xpalloc. The values are still always <= INT_MAX.
9860 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
9862 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
9863 (SAFE_NALLOCA): New macro.
9865 * region-cache.c (struct boundary.pos, find_cache_boundary)
9866 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
9867 (set_cache_region, invalidate_region_cache)
9868 (revalidate_region_cache, know_region_cache, region_cache_forward)
9869 (region_cache_backward, pp_cache):
9870 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
9871 so that ptrdiff_t * can be passed to xpalloc.
9872 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
9873 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
9874 (pp_cache): Don't assume cache_len fits in int.
9875 * region-cache.h: Adjust extern decls to match.
9877 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
9878 EMACS_INT, since either will do, for xpalloc.
9880 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
9881 (xnmalloc, xnrealloc, xpalloc): New functions.
9883 * bidi.c (bidi_shelve_header_size): New constant.
9884 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
9885 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
9887 * bidi.c (bidi_cache_shrink):
9888 * buffer.c (overlays_at, overlays_in, record_overlay_string)
9890 Don't update size of array until after memory allocation succeeds,
9891 because xmalloc/xrealloc may not return.
9892 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
9893 now that we have proper integer overflow checking.
9894 (record_overlay_string, overlay_strings): Catch overflows when
9895 calculating size of overlay_str_buf.
9897 * callproc.c (Fcall_process): Check for size overflow when
9898 calculating size of args2.
9899 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
9900 Normally we prefer signed values, but sticking with ptrdiff_t would
9901 require adding more-complicated checks.
9903 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
9904 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
9905 Redo buffer-overflow calculations to avoid integer overflow.
9906 Add a FIXME comment where memory seems to be over-allocated.
9908 * character.c (Fstring): Check for size-calculation overflow.
9910 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
9911 unnecessary integer overflow. Check for size overflow.
9912 (encode_coding_object): Don't update size until xmalloc succeeds.
9914 * composite.c (get_composition_id): Check for overflow in glyph
9915 length calculations.
9917 Integer and memory overflow fixes for display code.
9918 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
9919 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
9920 (scrolling_window): Check for overflow in size calculations.
9921 (line_draw_cost, realloc_glyph_pool, add_row_entry):
9922 Don't assume glyph table len fits in int.
9923 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
9924 (row_table_size): Now ptrdiff_t, not int.
9925 (scrolling_window): Avoid overflow in size calculations.
9926 Don't update size until allocation succeeds.
9927 * fns.c (concat): Check for overflow in size calculations.
9928 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
9929 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

9944 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
9946 * emacs.c (main): Do not reallocate argv, since there is a null at
9947 the end that can be overwritten, and this way there's no need to
9948 worry about size-calculation overflow.
9949 (sort_args): Check for size-calculation overflow.
9951 * eval.c (init_eval_once, grow_specpdl): Don't update size until

9971 Check for size-calculation overflow.
9972 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
9973 do, as we prefer signed integers.

10066 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10067 sizes, since they can exceed INT_MAX in size. Check for size

10078 (X_LONG_MIN): New macros.
10079 Use them to make the following changes clearer.
10080 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

10082 future maintainers not to raise the value too much later.
10083 (SELECTION_QUANTUM): Remove, replacing with ...
10084 (selection_quantum): ... new function, which avoids overflow.
10086 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10087 assumption that selection length fits in 'int'.

10104 Don't store size until memory allocation succeeds.
10105 (x_get_window_property): Plug memory leak on memory exhaustion.
10106 Don't double-block input; malloc is safe here. Don't assume 2**34
10107 - 4 fits in unsigned long. Add an xassert to check
10108 XGetWindowProperty overflow. Be more careful about overflow
10109 calculations, and distinguish size from memory overflow better.

10116 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10117 result parameters unless successful. Rely on cons_to_unsigned
10118 to report problems with elements; the old code wasn't right anyway.
10119 (x_check_property_data): Check for int overflow; we cannot use
10120 a wider type due to X limits.

10153 * lisp.h (hash_lookup, hash_put):
10154 * minibuf.c (Ftest_completion):
10155 Use ptrdiff_t for hash table indexes, not int (which is too
10156 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

10198 Change bufsize argument back to int, undoing my 2011-03-30 change.
10199 We prefer signed types, and int is wide enough here.
10200 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10201 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10202 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10203 length, not size_t. Use ptrdiff_t for index, not int.
10204 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10205 possibility of integer overflow.

10233 Prefer int to unsigned where either will do.
10234 (tiff_handler): New function, combining the cores of the
10235 old tiff_error_handler and tiff_warning_handler.

10237 stack buffer overflows. It uses only the features of vsnprintf
10238 that are common to both POSIX and native Microsoft.
10239 (tiff_error_handler, tiff_warning_handler): Use it.
10240 (tiff_load, gif_load, imagemagick_load_image):
10241 Don't assume :index value fits in 'int'.
10242 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

10287 positioning on the newline at EOL of R2L text within L2R
10288 paragraph, and vice versa.
10289 (try_cursor_movement): Check continued rows, in addition to
10290 continuation rows. Fixes unwarranted scroll when point enters a
10291 continued line of R2L text within an L2R paragraph, or vice versa.
10292 (cursor_row_p): Consider the case of point being equal to
10293 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

10322 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10323 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10324 candidate is selected by the mouse, and that candidate has a
10325 composed character under the mouse.
10327 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10328 coordinates reported by pos-visible-in-window-p for a composed

10338 consider it a hit if to_charpos is anywhere in the range of the
10339 composed buffer positions.
10341 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10343 * image.c (gif_load): Don't assume that each subimage has the same
10344 dimensions as the base image. Handle disposal method that is
10345 "undefined" by the gif spec (Bug#9335).
10347 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10349 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10361 with a composed character.
10363 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10365 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10366 character bidirectional type, use STRONG_L instead. Fixes crashes
10367 in a buffer produced by `describe-categories'.
10369 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10370 members before the level stack, so they would be saved and
10371 restored when copying iterator state. Fixes incorrect reordering
10372 around TABs covered by display properties.
10374 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10376 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
10378 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
10380 * eval.c (internal_condition_case, internal_condition_case_1)
10381 (internal_condition_case_2, internal_condition_case_n):
10382 Remove unnecessary aborts (Bug#9081).
10384 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10386 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10387 has no `load' handler, try opening the file locally. (Bug#9311)
10389 2011-08-16 Ken Brown <kbrown@cornell.edu>
10391 * gmalloc.c: Expand comment.
10393 2011-08-16 Eli Zaretskii <eliz@gnu.org>
10395 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
10396 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
10398 2011-08-16 Ken Brown <kbrown@cornell.edu>
10400 Fix memory allocation problems in Cygwin build (Bug#9273).
10402 * unexcw.c ( __malloc_initialized): Declare external variable.

10407 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10409 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10410 in the static heap.
10411 [CYGWIN] (special_realloc): New function.
10412 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
10413 requests to realloc storage in the static heap.

10424 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
10426 * dispextern.h: Fix a typo in the comment to bidi_type_t.
10428 * chartab.c: Improve commentary for the uniprop_table API.
10430 * bidi.c (bidi_paragraph_init): Support zero value of
10431 bidi_ignore_explicit_marks_for_paragraph_level.
10432 (bidi_initialize): Use uniprop_table instead of including
10433 biditype.h and bidimirror.h.
10435 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
10436 coordinates of the iterator when restoring from ppos_it.
10439 2011-08-14 Kenichi Handa <handa@m17n.org>
10441 * process.c (create_process): Call setup_process_coding_systems
10442 after the pid of the process is set to -1 (Bug#8162).
10444 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10446 * xdisp.c (move_it_in_display_line_to): Don't invoke
10447 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10448 ppos_it. Fixes vertical cursor motion when line beginning is
10449 covered by an image. (Bug#9296)
10451 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10453 * nsterm.h (ns_run_ascript): Declare.
10454 (NSAPP_DATA2_RUNASSCRIPT): Define.
10456 * nsfns.m (as_script, as_result, as_status): New static variables.
10457 (ns_run_ascript): New function.
10458 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10459 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10460 the event loop. Get status from as_status (Bug#7276).
10462 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10463 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10464 the event loop (Bug#7276).
10466 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10468 * gnutls.c (QCgnutls_bootprop_priority)
10469 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10470 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10471 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10472 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10473 (QCgnutls_bootprop_verify_hostname_error)
10474 (QCgnutls_bootprop_callbacks_verify): Rename from
10475 Qgnutls_bootprop_..., all uses changed.
10477 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
10480 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
10482 * xfaces.c (Qframe_set_background_mode): Now static.
10483 * dispextern.h (Qframe_set_background_mode): Remove decl.

10487 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
10489 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10490 (Fnetwork_interface_list): Allocate in increments of bytes instead
10491 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10492 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10494 (struct ifflag_def): notrailers is smart on OSX.
10495 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10496 Get hardware address with getifaddrs if available.
10498 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10500 * xdisp.c (iterate_out_of_display_property): xassert that
10501 IT->position is set to within IT->object's boundaries. Break from
10502 the loop as soon as EOB is reached; avoids infloops in redisplay
10503 when IT->position is set up wrongly due to some bug.
10504 Set IT->current to match the bidi iterator unconditionally.
10505 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10506 entry. Force push_it to save on the stack the current
10507 buffer/string position, to be restored by pop_it. Fix flags in
10508 the iterator structure wrt the object coming from a display
10509 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10510 properties. (Bug#9284)
10512 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10514 * fontset.c (fontset_get_font_group): Add proper type checks.
10517 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10519 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
10520 and LC_VERSION_MIN_MACOSX.
10521 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
10522 (dump_it) [LC_FUNCTION_STARTS]: Use it.
10524 2011-08-08 Eli Zaretskii <eliz@gnu.org>
10526 * xdisp.c (forward_to_next_line_start): Allow to use the
10527 no-display-properties-and-no-overlays under bidi display.
10528 Set disp_pos in the bidi iterator to avoid searches for display
10529 properties and overlays.
10531 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10533 * editfns.c (Fset_time_zone_rule): Document relationship with the
10536 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
10537 the font entity extracted from the cache (Bug#8109).
10539 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10541 * composite.c (autocmp_chars): Don't reset point. That is done by
10542 restore_point_unwind (Bug#5984).
10544 2011-08-07 Juri Linkov <juri@jurta.org>
10546 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10547 to show the arg `TIME' instead of `TIMEVAL'.
10549 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10551 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10552 display property strides EOL and includes a newline, as in
10553 longlines-mode. (Bug#9254)
10554 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10555 word-wrap under bidirectional display. (Bug#9224)
10557 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10558 is non-zero, even if the data buffer is NULL. Fixes a crash in
10559 vertical-motion with longlines-mode. (Bug#9254)
10561 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10563 * bidi.c <bidi_cache_total_alloc>: Now static.
10564 (bidi_initialize): Initialize bidi_cache_total_alloc.
10566 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10569 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10570 amount allocated this far in `bidi_cache_total_alloc'.
10571 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10572 non-zero, only free the data buffer without restoring the cache
10573 contents. All callers changed.
10575 * dispextern.h (bidi_unshelve_cache): Update prototype.
10577 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10578 (move_it_in_display_line, move_it_to)
10579 (move_it_vertically_backward, move_it_by_lines): Replace the call
10580 to xfree to an equivalent call to bidi_unshelve_cache.
10581 (move_it_in_display_line_to): Fix logic of returning
10582 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
10584 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10586 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
10587 came from a string character with a `cursor' property. (Bug#9229)
10589 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10591 * Makefile.in (LIB_PTHREAD): New variable.
10592 (LIBES): Add LIB_PTHREAD (Bug#9216).
10594 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
10595 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
10597 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
10599 * regex.c (re_iswctype): Remove some redundant boolean conversions.
10601 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10603 * xterm.c (x_find_topmost_parent): New function.
10604 (x_set_frame_alpha): Find topmost parent window with
10605 x_find_topmost_parent and set the property there also (bug#9181).
10606 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
10608 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
10610 * callproc.c (Fcall_process): Avoid vfork clobbering
10611 the local vars buffer, coding_systems, current_dir.
10613 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
10615 * keymap.c (Fmake_composed_keymap): Move to subr.el.
10617 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
10619 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
10620 so that it is not optimized away.
10622 * xdisp.c (compute_display_string_pos): Remove unused local.
10624 2011-08-02 Eli Zaretskii <eliz@gnu.org>
10626 Fix slow cursor motion and scrolling in large buffers with
10627 selective display, like Org Mode buffers. (Bug#9218)
10629 * dispextern.h (struct bidi_it): New member disp_prop_p.
10631 * xdisp.c: Remove one-slot cache of display string positions.
10632 (compute_display_string_pos): Accept an additional argument
10633 DISP_PROP_P; callers changed. Scan at most 5K characters forward
10634 for a display string or property. If found, set DISP_PROP_P
10637 * bidi.c (bidi_fetch_char): Accept an additional argument
10638 DISP_PROP_P, and pass it to compute_display_string_pos.
10639 Only handle text covered by a display string if DISP_PROP_P is returned
10640 non-zero. All callers of bidi_fetch_char changed.
10642 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
10644 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
10646 2010-12-03 Don March <don@ohspite.net>
10648 * keymap.c (Fdefine_key): Fix non-prefix key error message when
10649 last character M-[char] is translated to ESC [char] (bug#7541).
10651 2011-08-02 Kenichi Handa <handa@m17n.org>
10653 * lisp.h (uniprop_table): Extern it.
10655 * chartab.c (uniprop_table): Make it non-static.
10657 2011-08-01 Eli Zaretskii <eliz@gnu.org>
10659 * xdisp.c (forward_to_next_line_start): Accept additional argument
10660 BIDI_IT_PREV, and store into it the state of the bidi iterator had
10662 (reseat_at_next_visible_line_start): Use the bidi iterator state
10663 returned by forward_to_next_line_start to restore the state of
10664 it->bidi_it after backing up to previous newline. (Bug#9212)
10666 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
10668 * regex.c (re_comp): Protoize.
10669 (re_exec): Fix return type.
10670 (regexec): Fix type of `ret'. (Bug#9203)
10672 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10674 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
10675 This is needed if max-image-size is a floating-point number.
10677 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10679 * print.c (print_object): Print empty symbol as ##.
10681 * lread.c (read1): Read ## as empty symbol.
10683 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10685 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
10686 setting frame foreground color (Bug#9175).
10687 (x_set_background_color): Likewise.
10689 * nsmenu.m (-setText): Size tooltip dimensions precisely to
10690 contents (Bug#9176).
10691 (EmacsTooltip -init): Remove bezels and add shadows to
10694 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
10695 or scroll bar (Bug#8470).
10697 * nsfont.m (nsfont_open): Remove assignment to voffset and
10698 unnecessary vars hshink, expand, hd, full_height, min_height.
10699 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
10701 * nsterm.h (nsfont_info): Remove voffset field.
10703 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10705 Implement strike-through and overline on NextStep (Bug#8863).
10707 * nsfont.m (nsfont_open): Use underline position provided by font,
10708 instead of hard-coded value of 2.
10709 (nsfont_draw): Call ns_draw_text_decoration instead.
10711 * nsterm.h: Add declaration for ns_draw_text_decoration.
10713 * nsterm.m (ns_draw_text_decoration): New function for drawing
10714 underline, overline, and strike-through.
10715 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
10716 ns_draw_text_decoration. Change treatment of cursor drawing to
10717 accommodate underlining, etc.
10719 2011-07-28 Eli Zaretskii <eliz@gnu.org>
10721 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
10724 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10726 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
10727 Without this fix, if a signal arrives just after memory fills up,
10728 'malloc' might be invoked reentrantly.
10730 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
10731 In other words, assume that every image size is allowed, on non-X
10732 hosts. This assumption is probably wrong, but it lets Emacs compile.
10734 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10736 * regex.c (re_iswctype): Convert return values to boolean.
10738 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
10740 * xdisp.c (compute_display_string_pos): Don't use cached display
10741 string position if the buffer had its restriction changed.
10744 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10746 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10748 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10750 Integer signedness and overflow and related fixes. (Bug#9079)
10752 * bidi.c: Integer size and overflow fixes.
10753 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
10754 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
10755 (bidi_cache_find_level_change, bidi_cache_ensure_space)
10756 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
10757 (bidi_find_other_level_edge):
10758 Use ptrdiff_t instead of EMACS_INT where either will do.
10759 This works better on 32-bit hosts configured --with-wide-int.
10760 (bidi_cache_ensure_space): Check for size-calculation overflow.
10761 Use % rather than repeated addition, for better worst-case speed.
10762 Don't set bidi_cache_size until after xrealloc returns, because it
10764 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
10765 (bidi_cache_ensure_space): Also check that the bidi cache size
10766 does not exceed that of the largest Lisp string or buffer. See Eli
10767 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
10769 * alloc.c (__malloc_size_t): Remove.
10770 All uses replaced by size_t. See Andreas Schwab's note
10771 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
10773 * image.c: Improve checking for integer overflow.
10774 (check_image_size): Assume that f is nonnull, since
10775 it is always nonnull in practice. This is one less thing to
10776 worry about when checking for integer overflow later.
10777 (x_check_image_size): New function, which checks for integer
10778 overflow issues inside X.
10779 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
10780 This removes the need for a memory_full check.
10781 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
10782 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
10783 (xbm_read_bitmap_data): Change locals back to 'int', since
10784 their values must fit in 'int'.
10785 (xpm_load_image, png_load, tiff_load):
10786 Invoke x_create_x_image_and_pixmap earlier,
10787 to avoid much needless work if the image is too large.
10788 (tiff_load): Treat overly large images as if
10789 x_create_x_image_and_pixmap failed, not as malloc failures.
10790 (gs_load): Use x_check_image_size.
10792 * gtkutil.c: Omit integer casts.
10793 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
10794 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
10796 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
10798 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
10799 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
10800 would wrongly return t on a 64-bit host.
10802 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
10803 The plain *_OVERFLOW macros run afoul of GCC bug 49705
10804 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
10805 and therefore cause GCC to emit a bogus diagnostic in some cases.
10807 * image.c: Integer signedness and overflow and related fixes.
10808 This is not an exhaustive set of fixes, but it's time to
10809 record what I've got.
10810 (lookup_pixel_color, check_image_size): Remove redundant decls.
10811 (check_image_size): Don't assume that arbitrary EMACS_INT values
10812 fit in 'int', or that arbitrary 'double' values fit in 'int'.
10813 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
10814 (tiff_load, imagemagick_load_image):
10815 Check for overflow in size calculations.
10816 (x_create_x_image_and_pixmap): Remove unnecessary test for
10817 xmalloc returning NULL; that can't happen.
10818 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
10819 (xpm_color_bucket): Use better integer hashing function.
10820 (xpm_cache_color): Don't possibly over-allocate memory.
10821 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
10822 (gif_memory_source):
10823 Use ptrdiff_t, not int or size_t, to record sizes.
10824 (png_load): Don't assume values greater than 2**31 fit in 'int'.
10825 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
10826 either works, as we prefer signed integers.
10827 (tiff_read_from_memory, tiff_write_from_memory):
10828 Return tsize_t, not size_t, since that's what the TIFF API wants.
10829 (tiff_read_from_memory): Don't fail simply because the read would
10830 go past EOF; instead, return a short read.
10831 (tiff_load): Omit no-longer-needed casts.
10832 (Fimagemagick_types): Don't assume size fits into 'int'.
10834 Improve hashing quality when configured --with-wide-int.
10835 * fns.c (hash_string): New function, taken from sxhash_string.
10836 Do not discard information about ASCII character case; this
10837 discarding is no longer needed.
10838 (sxhash-string): Use it. Change sig to match it. Caller changed.
10839 * lisp.h: Declare it.
10840 * lread.c (hash_string): Remove, since we now use fns.c's version.
10841 The fns.c version returns a wider integer if --with-wide-int is
10842 specified, so this should help the quality of the hashing a bit.
10844 * emacs.c: Integer overflow minor fix.
10845 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
10846 Define only if GNU_LINUX.
10847 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
10849 * dispnew.c: Integer signedness and overflow fixes.
10850 Remove unnecessary forward decls, that were a maintenance hassle.
10851 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
10853 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
10854 (scrolling_window): Use ptrdiff_t, not int, for byte count.
10855 (prepare_desired_row, line_draw_cost):
10856 Use int, not unsigned, where either works.
10857 (save_current_matrix, restore_current_matrix):
10858 Use ptrdiff_t, not size_t, where either works.
10859 (init_display): Check for overflow more accurately, and without
10860 relying on undefined behavior.
10862 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
10863 Remove, replacing with the new symbols in lisp.h. All uses changed.
10864 * fileio.c (make_temp_name):
10865 * filelock.c (lock_file_1, lock_file):
10866 * xdisp.c (message_dolog):
10867 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
10868 Use pMd etc. instead.
10869 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
10870 replacing the pWIDE etc. symbols removed from editfns.c.
10872 * keyboard.h (num_input_events): Now uintmax_t.
10873 This is (very slightly) less likely to mess up due to wraparound.
10876 * buffer.c: Integer signedness fixes.
10877 (alloc_buffer_text, enlarge_buffer_text):
10878 Use ptrdiff_t rather than size_t when either will do, as we prefer
10881 * alloc.c: Integer signedness and overflow fixes.
10882 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
10883 (__malloc_size_t): Default to size_t, not to int.
10884 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
10885 (Fgarbage_collect, mark_object_loop_halt, mark_object):
10886 Prefer ptrdiff_t to size_t when either would do, as we prefer
10888 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
10889 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
10890 Now const. Initialize with values that are in range even if char
10892 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
10893 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
10894 These functions do the right thing with sizes > 2**32.
10895 (check_depth): Now ptrdiff_t, not int.
10896 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
10897 Adjust to new way of storing sizes. Check for size overflow bugs
10899 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
10900 slightly wrong anyway, as it missed one instance of
10901 XMALLOC_OVERRUN_CHECK_OVERHEAD.
10902 (refill_memory_reserve): Omit needless cast to size_t.
10903 (mark_object_loop_halt): Mark as externally visible.
10905 * xselect.c: Integer signedness and overflow fixes.
10906 (Fx_register_dnd_atom, x_handle_dnd_message):
10907 Use ptrdiff_t, not size_t, since we prefer signed.
10908 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
10909 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
10910 x_dnd_atoms_size and x_dnd_atoms_length.
10912 * doprnt.c: Prefer signed to unsigned when either works.
10914 * doprnt.c (doprnt):
10916 * xdisp.c (vmessage):
10917 Use ptrdiff_t, not size_t, when using or implementing doprnt,
10918 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
10919 prefer signed arithmetic to avoid comparison confusion.
10920 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
10921 but is a bit tricky.
10923 Assume freestanding C89 headers, string.h, stdlib.h.
10924 * data.c, doprnt.c, floatfns.c, print.c:
10925 Include float.h unconditionally.
10926 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10927 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10928 * regex.c: Likewise for stddef.h, string.h.
10929 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10930 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10931 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10932 (STDC_HEADERS): Remove obsolete defines.
10933 * sysdep.c: Include limits.h unconditionally.
10935 Assume support for memcmp, memcpy, memmove, memset.
10936 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10937 * regex.c (memcmp, memcpy):
10938 Remove; we assume C89 now.
10940 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
10941 (__malloc_safe_bcopy): Remove; no longer needed.
10943 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
10944 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
10945 well either way, and we prefer signed to unsigned.
10947 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
10949 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
10950 closes the connection while we're reading (bug#9182).
10952 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10954 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
10955 are specified (Bug#9168).
10957 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
10959 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
10960 Found by GCC static checking and --with-wide-int on a 32-bit host.
10962 2011-07-25 Eli Zaretskii <eliz@gnu.org>
10964 * xdisp.c (compute_display_string_pos): Fix logic of caching
10965 previous display string position. Initialize cached_prev_pos to
10966 -1. Fixes slow-down at the beginning of a buffer.
10968 2011-07-24 Eli Zaretskii <eliz@gnu.org>
10970 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
10971 for attrs[LFACE_FONTSET_INDEX].
10973 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
10975 * xml.c (parse_region): Remove unused local
10976 that was recently introduced.
10978 2011-07-23 Eli Zaretskii <eliz@gnu.org>
10980 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
10981 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
10983 * xdisp.c (move_it_in_display_line_to): Record the best matching
10984 position for TO_CHARPOS while scanning the line, and restore it on
10985 exit if none of the characters scanned was an exact match.
10986 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
10987 when exact match is impossible due to invisible text, and the
10988 lines are truncated.
10990 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
10992 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
10995 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10997 Fix a significant slow-down of cursor motion with C-n, C-p,
10998 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
10999 auto-repeat under bidi redisplay in fontified buffers.
11000 * xdisp.c (compute_stop_pos_backwards): New function.
11001 (next_element_from_buffer): Call compute_stop_pos_backwards to
11002 find a suitable prev_stop when we find ourselves before
11004 (reseat): Don't look for prev_stop, as that could mean a very long
11006 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11007 <cached_disp_overlay_modiff>: Cache for last found display string
11009 (compute_display_string_pos): Return the cached position if asked
11010 about the same buffer in the same area of character positions, and
11011 the buffer wasn't changed since the time the display string
11012 position was cached.
11014 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11016 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11017 is an integer, which is important for empty lines. (Bug#9149)
11019 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11021 * frame.c (Fmodify_frame_parameters): In tty case, update the
11022 default face if necessary (Bug#4238).
11024 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11026 * editfns.c (Fstring_to_char): No need to explain what a character
11027 is in the docstring (Bug#6576).
11029 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11031 * xml.c (parse_region): Make sure we always return a tree.
11033 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11035 * xml.c (parse_region): If a document contains only comments,
11038 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11040 * xml.c (make_dom): Return comments, too.
11042 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11045 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11046 and the surrounding thread.
11047 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11048 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11049 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11051 * s/openbsd.h (BROKEN_SIGIO): Define.
11052 * unexelf.c (unexec) [__OpenBSD__]:
11053 Don't update the .mdebug section of the Alpha COFF symbol table.
11055 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11057 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11060 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11062 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11063 This fixes some race conditions on the permissions of any newly
11066 * alloc.c (valid_pointer_p): Use pipe, not open.
11067 This fixes some permissions issues when debugging.
11069 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11070 If fchown fails to set both uid and gid, try to set just gid,
11071 as that is sometimes allowed. Adjust the file's mode to eliminate
11072 setuid or setgid bits that are inappropriate if fchown fails.
11074 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11076 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11077 to compare Lisp_Objects.
11078 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11079 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11080 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11082 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11084 * lread.c (read_integer): Unread even EOF character.
11085 (read1): Likewise. Properly record start position of symbol.
11087 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11088 symbol character follows.
11090 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11092 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11093 This works around a problem with the previous change to Fcopy_file.
11094 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11095 and without this change, GCC might complain about discarding
11096 fchown's return value.
11098 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11100 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11102 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11104 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11106 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11108 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11109 it's used from the C level.
11111 * process.c: Use the same condition for POLL_FOR_INPUT in both
11112 keyboard.c and process.c (bug#1858).
11114 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11116 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11117 (Fgnutls_boot): Use it.
11119 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11121 * doc.c (Fsubstitute_command_keys): Revert last change.
11123 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11125 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11126 quotes the next character, and doesn't affect other longer
11127 sequences (bug#8935).
11129 * lread.c (syms_of_lread): Clarify that is isn't only
11130 `eval-buffer' and `eval-defun' that's affected by
11131 `lexical-binding' (bug#8460).
11133 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11135 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11136 bidi redisplay when a line includes both an image and is truncated.
11138 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11140 Fix minor problems found by static checking.
11141 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11142 (elsz): Now a signed constant, not a size_t var. We prefer signed
11143 types to unsigned, to avoid integer comparison confusion. Without
11144 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11145 "cannot optimize loop, the loop counter may overflow", a symptom
11147 * indent.c (Fvertical_motion): Mark locals as initialized.
11148 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11150 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11152 * search.c (Fre_search_backward): Mention `case-fold-search' in
11153 all the re_search_* functions (bug#8138).
11155 * keyboard.c (Fopen_dribble_file): Document when the file is
11158 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11160 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11163 Support bidi reordering of display and overlay strings.

11165 (compute_display_string_end): Accept additional argument STRING.
11166 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11167 (reseat_to_string): Initialize bidi_it->string.s and
11168 bidi_it->string.schars.
11169 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11170 NULL (avoids a crash in bidi_paragraph_init).
11171 Initialize itb.string.lstring.
11172 (init_iterator): Call bidi_init_it only of a valid
11173 buffer position was specified. Initialize paragraph_embedding to
11175 (reseat_to_string): Initialize the bidi iterator.
11176 (display_string): If we need to ignore text properties of
11177 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11178 original value of -1 will not work with bidi.)
11179 (compute_display_string_pos): First arg is now struct
11180 `text_pos *'; all callers changed. Support display properties on
11182 (compute_display_string_end): Support display properties on Lisp
11184 (init_iterator, reseat_1, reseat_to_string): Initialize the
11185 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11186 when iterating on a string not from display properties).
11187 (compute_display_string_pos, compute_display_string_end):
11188 Fix calculation of the object to scan. Fixes an error when using
11190 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11191 base_level_stop; instead, set base_level_stop to BEGV.
11192 Fixes crashes in vertical-motion.
11193 (next_element_from_buffer): Improve commentary for when
11194 the iterator is before prev_stop.
11195 (init_iterator): Initialize bidi_p from the default value of
11196 bidi-display-reordering, not from buffer-local value. Use the
11197 buffer-local value only if initializing for buffer iteration.
11198 (handle_invisible_prop): Support invisible properties on strings
11199 that are being bidi-reordered.
11200 (set_iterator_to_next): Support bidi reordering of C strings and
11202 (next_element_from_string): Support bidi reordering of Lisp
11204 (handle_stop_backwards): Support Lisp strings as well.
11205 (display_string): Support display of R2L glyph rows.
11206 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11207 (init_iterator): Don't initialize it->bidi_p for strings
11209 (reseat_to_string): Initialize it->bidi_p for strings here.
11210 (next_element_from_string, next_element_from_c_string)
11211 (next_element_from_buffer): Add xassert's for correspondence
11212 between IT's object being iterated and it->bidi_it.string
11214 (face_before_or_after_it_pos): Support bidi iteration.
11215 (next_element_from_c_string): Handle the case of the first string
11216 character that is not the first one in the visual order.
11217 (get_visually_first_element): New function, refactored from common
11218 parts of next_element_from_buffer, next_element_from_string, and
11219 next_element_from_c_string.
11220 (tool_bar_lines_needed, redisplay_tool_bar)
11221 (display_menu_bar): Force left-to-right direction. Add a FIXME
11222 comment for making that be controlled by a user option.
11223 (push_it, pop_it): Save and restore the state of the
11224 bidi iterator. Save and restore the bidi_p flag.
11225 (pop_it): Iterate out of display property for string iteration as
11227 (iterate_out_of_display_property): Support iteration over strings.
11228 (handle_single_display_spec): Set up it->bidi_it for iteration
11229 over a display string, and call bidi_init_it.
11230 (handle_single_display_spec, next_overlay_string)
11231 (get_overlay_strings_1, push_display_prop): Set up the bidi
11232 iterator for displaying display or overlay strings.
11233 (forward_to_next_line_start): Don't use the shortcut if
11235 (back_to_previous_visible_line_start): If handle_display_prop
11236 pushed the iterator stack, restore the internal state of the bidi
11237 iterator by calling bidi_pop_it same number of times.
11238 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11239 and we are bidi-iterating, don't decrement the iterator position;
11240 instead, set the first_elt flag in the bidi iterator, to produce
11242 (reseat_1): Remove redundant setting of string_from_display_prop_p.
11243 (push_display_prop): xassert that we are iterating a buffer.
11244 (push_it, pop_it): Save and restore paragraph_embedding member.
11245 (handle_single_display_spec, next_overlay_string)
11246 (get_overlay_strings_1, reseat_1, reseat_to_string)
11247 (push_display_prop): Set up the `unibyte' member of bidi_it.string
11248 correctly. Don't assume unibyte strings are not bidi-reordered.
11249 (compute_display_string_pos)
11250 (compute_display_string_end): Fix handling the case of C string.
11251 (push_it, pop_it): Save and restore from_disp_prop_p.
11252 (handle_single_display_spec, push_display_prop): Set the
11253 from_disp_prop_p flag.
11254 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
11255 (pop_it): Call iterate_out_of_display_property only if we are
11256 popping after iteration over a string that came from a display
11257 property. Fix a typo in popping stretch info. Add an assertion
11258 for verifying that the iterator position is in sync with the bidi
11260 (handle_single_display_spec, get_overlay_strings_1)
11261 (push_display_prop): Fix initialization of paragraph direction for
11262 string when that of the parent object is not yet determined.
11263 (reseat_1): Call bidi_init_it to resync the bidi
11264 iterator with IT's position. (Bug#7616)

11711 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
11713 Random fixes. E.g., (random) never returned negative values.
11714 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
11715 subseconds part to the entropy, as that's a bit more random.
11716 Prefer signed to unsigned, since the signedness doesn't matter and
11717 in general we prefer signed. When given a limit, use a
11718 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
11719 latter isn't right if USE_2_TAGS_FOR_INTS.
11720 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
11721 not 0..VALMASK. Don't discard "excess" bits that random () returns.
11723 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11725 * textprop.c (text_property_stickiness):
11726 Obey Vtext_property_default_nonsticky.

11733 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
11734 This is more efficient than Ffile_directory_p and avoids a minor race.
11736 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
11738 * buffer.c (Foverlay_put): Say what the return value is
11741 * fileio.c (barf_or_query_if_file_exists): Check first if the file
11742 is a directory before asking whether to use the file name
11744 (barf_or_query_if_file_exists): Make the "File is a directory"
11745 error be more correct.
11747 * fns.c (Frequire): Remove the mention of the .gz files, since
11748 that's installation-specific, but keep the mention of
11749 `get-load-suffixes'.
11751 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
11753 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

11758 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
11759 (syms_of_gnutls): Remove duplicate DEFSYM for
11760 Qgnutls_bootprop_verify_hostname_error, an error for
11761 Qgnutls_bootprop_verify_error (which is no longer used).
11763 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
11764 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
11765 Also (re)move comments that are misplaced or no longer relevant.
11767 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11769 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

11773 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
11774 and background color parameters if they have been changed.

11794 * lread.c (syms_of_lread): Mention single symbols defined by
11795 `defvar' or `defconst' (bug#7154).
11797 * fns.c (Frequire): Mention .el.gz files (bug#7314).
11798 (Frequire): Mention get-load-suffixes.
11800 2011-07-02 Martin Rudalics <rudalics@gmx.at>

11866 * eval.c (struct backtrace): Simplify and port the data structure.
11867 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
11868 signed bit field, as this assumption is not portable and it makes
11869 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
11870 "char debug_on_exit : 1" as this is not portable either; instead,
11871 use the portable "unsigned int debug_on_exit : 1". Remove unused
11872 member evalargs. Remove obsolete comments about cc bombing out.
11874 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
11876 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

11944 (emacs_fixed_get_preferred_height): Use min_width/height from
11945 frames size_hint to set minimum and natural (Bug#8919).
11946 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
11947 and use min_width/height from frames size_hint to set
11948 min_width/height (Bug#8919).

12040 * print.c (printchar, strout): Check for string overflow.
12041 (PRINTPREPARE, printchar, strout):
12042 Don't set size unless allocation succeeds.
12044 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12045 for sizes. Check for string overflow more accurately.

12060 to improve quality of diagnostics for out-of-range radices.
12061 Calculate buffer size correctly for out-of-range radices.
12062 (read1): Check for integer overflow in radices, and in
12063 read-circle numbers.
12064 (read_escape): Avoid int overflow.
12065 (Fload, openp, read_buffer_size, read1)
12066 (substitute_object_recurse, read_vector, read_list, map_obarray):
12067 Use ptrdiff_t, not int, for sizes.

12087 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12089 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12090 The following patches are for when GLYPH_DEBUG && !XASSERT.
12091 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12092 * dispnew.c (flush_stdout):
12093 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12094 Mark as externally visible.
12095 * dispnew.c (check_window_matrix_pointers): Now static.
12096 * dispnew.c (window_to_frame_vpos):
12097 * xfns.c (unwind_create_frame):
12098 * xterm.c (x_check_font): Remove unused local.
12099 * scroll.c (CHECK_BOUNDS):
12100 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12101 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.

12104 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12106 (debug_method_add): Use va_list and vsprintf rather than relying
12107 on undefined behavior with wrong number of arguments.
12108 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12109 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12110 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12111 since we're not interested in debugging glyphs with old libraries.
12112 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12113 GCC 4.6.0's static checking.
12115 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

12139 Use ptrdiff_t, not int, for overlay counts.
12140 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12141 * editfns.c (overlays_around, get_pos_property):
12142 * textprop.c (get_char_property_and_overlay):
12143 * xdisp.c (next_overlay_change, note_mouse_highlight):
12144 * xfaces.c (face_at_buffer_position):
12145 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12146 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12147 (Fnext_overlay_change, Fprevious_overlay_change)
12148 (mouse_face_overlay_overlaps, Foverlays_in):
12149 Use ptrdiff_t, not int, for sizes.
12150 (overlays_at, overlays_in): Check for size-calculation overflow.
12152 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12154 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12155 (x_session_initialize): Do not assume string length fits in int.
12157 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12158 This is unlikely, but can occur if DPI is outlandish.
12160 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12161 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12163 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12164 * xrdb.c (magic_file_p, search_magic_path):
12165 Omit last arg SUFFIX; it was always 0. All callers changed.
12166 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12168 * xfont.c (xfont_match): Avoid need for strlen.
12170 * xfns.c: Don't assume strlen fits in int.
12171 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12173 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12174 not unsigned long, as we prefer signed integers. All callers changed.
12175 Detect integer overflow in repeat count.
12176 (message_dolog): Don't assume print length fits in 39 bytes.
12177 (display_mode_element): Don't assume strlen fits in int.
12179 * termcap.c: Don't assume sizes fit in int and never overflow.
12180 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12181 (gobble_line): Check for size-calculation overflow.
12183 * minibuf.c (Fread_buffer):
12184 * lread.c (intern, intern_c_string):
12185 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12186 Don't assume string length fits in int.
12188 * keyboard.c (parse_tool_bar_item):
12189 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12191 * font.c: Don't assume string length fits in int.
12192 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12193 Use ptrdiff_t, not int.
12194 (font_intern_prop): Don't assume string length fits in int.
12195 Don't assume integer property fits in fixnum.
12196 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12198 * filelock.c: Fix some buffer overrun and integer overflow issues.
12199 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12200 Reformulate so as not to need the command string.
12201 Invoke gzip -cd rather than gunzip, as it's more portable.
12202 (lock_info_type, lock_file_1, lock_file):
12203 Don't assume pid_t and time_t fit in unsigned long.
12204 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12205 (current_lock_owner): Prefer signed type for sizes.
12206 Use memcpy, not strncpy, where memcpy is what is really wanted.
12207 Don't assume (via atoi) that time_t and pid_t fit in int.
12208 Check for time_t and/or pid_t out of range, e.g., via a network share.
12209 Don't alloca where an auto var works fine.
12211 * fileio.c: Fix some integer overflow issues.
12212 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12213 Don't assume string length fits in int.
12214 (directory_file_name): Don't assume string length fits in long.
12215 (make_temp_name): Don't assume pid fits in int, or that its print
12216 length is less than 20.
12218 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12220 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12222 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12224 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12225 We prefer signed integers, even for size calculations.
12227 * emacs.c: Don't assume string length fits in 'int'.
12228 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12229 (main): Don't invoke strlen when not needed.
12231 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12232 (XD_DEBUG_MESSAGE): Don't waste a byte.
12234 * callproc.c (getenv_internal_1, getenv_internal)
12235 (Fgetenv_internal):
12236 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12238 * lread.c (invalid_syntax): Omit length argument.
12239 All uses changed. This doesn't fix a bug, but it simplifies the
12240 code away from its former Hollerith-constant appearance, and it's
12241 one less 'int' to worry about when looking at integer-overflow issues.
12242 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12244 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12245 This didn't break anything, but it didn't help either.
12246 It's confusing to put a bogus integer in a place where the actual
12247 value does not matter.
12248 (LIST_END_P): Remove unused macro and its bogus comment.
12249 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12251 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12252 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12254 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12255 We prefer signed types, and the value cannot exceed the EMACS_INT
12256 range anyway (because otherwise the length would not be representable).
12257 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12258 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12259 This avoids a GCC warning when WIDE_EMACS_INT.
12261 * indent.c (sane_tab_width): New function.
12262 (current_column, scan_for_column, Findent_to, position_indentation)
12263 (compute_motion): Use it. This is just for clarity.
12264 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12266 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12268 * lisp.h (lint_assume): New macro.
12269 * composite.c (composition_gstring_put_cache):
12270 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12272 * editfns.c, insdel.c:
12273 Omit unnecessary forward decls, to simplify future changes.
12275 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12277 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12279 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12280 Use much-faster test for byte-length change.
12281 Don't assume string byte-length fits in 'int'.
12282 Check that character arg fits in 'int'.
12283 (mapcar1): Declare byte as byte, for clarity.
12285 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12287 * fns.c (concat): Catch string overflow earlier.
12288 Do not rely on integer wraparound.
12290 * dispextern.h (struct it.overlay_strings_charpos)
12291 (struct it.selective): Now EMACS_INT, not int.
12292 * xdisp.c (forward_to_next_line_start)
12293 (back_to_previous_visible_line_start)
12294 (reseat_at_next_visible_line_start, next_element_from_buffer):
12295 Don't arbitrarily truncate the value of 'selective' to int.
12297 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12299 * composite.c: Don't truncate sizes to 'int'.
12300 (composition_gstring_p, composition_reseat_it)
12301 (composition_adjust_point): Use EMACS_INT, not int.
12302 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12303 not EMACS_UINT, for indexes.
12305 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12307 * buffer.c: Include <verify.h>.
12308 (struct sortvec.priority, struct sortstr.priority):
12309 Now EMACS_INT, not int.
12310 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12311 (struct sortstr.size, record_overlay_string)
12312 (struct sortstrlist.size, struct sortlist.used):
12313 Don't truncate size to int.
12314 (record_overlay_string): Check for size-calculation overflow.
12315 (init_buffer_once): Check at compile-time, not run-time.
12317 2011-06-22 Jim Meyering <meyering@redhat.com>
12319 Don't leak an XBM-image-sized buffer
12320 * image.c (xbm_load): Free the image buffer after using it.
12322 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12325 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12326 that Sun C diagnosed.
12327 * fns.c (secure_hash): Fix pointer signedness issue.
12328 * intervals.c (static_offset_intervals): New function.
12329 (offset_intervals): Use it.
12331 2011-06-21 Leo Liu <sdl.web@gmail.com>
12334 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12337 * fns.c (secure_hash): Rename from crypto_hash_function and change
12338 the first arg to accept symbols.
12339 (Fsecure_hash): New primitive.
12340 (syms_of_fns): New symbols.
12342 2011-06-20 Deniz Dogan <deniz@dogan.se>
12344 * process.c (Fset_process_buffer): Clarify return value in
12347 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12349 * dispnew.c (add_window_display_history): Use BVAR.
12351 * xdisp.c (debug_method_add): Use BVAR.
12352 (check_window_end, dump_glyph_matrix, dump_glyph)
12353 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12355 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12358 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12359 check till after the cache is created in init_frame_faces.
12361 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12363 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12365 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12367 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12368 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12369 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12371 Improve buffer-overflow checking (Bug#8873).
12372 * fileio.c (Finsert_file_contents):
12373 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12374 Remove the old (too-loose) buffer overflow checks.
12375 They weren't needed, since make_gap checks for buffer overflow.
12376 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12377 The old code merely checked for Emacs fixnum overflow, and relied
12378 on undefined (wraparound) behavior. The new code avoids undefined
12379 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12381 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12382 Tune. Don't use wider integers than needed. Don't use alloca.
12383 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12385 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12387 * insdel.c, lisp.h (buffer_overflow): New function.
12388 (insert_from_buffer_1, replace_range, replace_range_2):
12389 * insdel.c (make_gap_larger):
12390 * editfns.c (Finsert_char):
12391 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12393 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12395 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12397 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12399 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12400 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12402 * fileio.c: Don't assume EMACS_INT fits in off_t.
12403 (emacs_lseek): New static function.
12404 (Finsert_file_contents, Fwrite_region): Use it.
12405 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12407 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12409 * fns.c: Don't overflow int when computing a list length.
12410 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12411 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12412 truncation on 64-bit hosts. Check for QUIT every
12413 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12414 faster and is responsive enough.
12415 (Flength): Report an error instead of overflowing an integer.
12416 (Fsafe_length): Return a float if the value is not representable
12417 as a fixnum. This shouldn't happen except in contrived situations.
12418 (Fnthcdr, Fsort): Don't assume list length fits in int.
12419 (Fcopy_sequence): Don't assume vector length fits in int.
12421 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12422 (header_size, word_size): New constants.
12423 (allocate_vectorlike): Don't check size overflow here.
12424 (allocate_vector): Check it here instead, since this is the only
12425 caller of allocate_vectorlike that could cause overflow.
12426 Check that the new vector's length is representable as a fixnum.
12428 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12429 The previous code was bogus. For example, next_almost_prime (32)
12430 returned 39, which is undesirable as it is a multiple of 3; and
12431 next_almost_prime (24) returned 25, which is a multiple of 5 so
12432 why was the code bothering to check for multiples of 7?
12434 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12436 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12438 Variadic C functions now count arguments with ptrdiff_t.
12439 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12440 Back then I didn't know that the Emacs coding style prefers signed int.
12441 Also, in the meantime I found a few more instances where arguments
12442 were being counted with int, which may truncate counts on 64-bit
12443 machines, or EMACS_INT, which may be unnecessarily wide.
12444 * lisp.h (struct Lisp_Subr.function.aMANY)
12445 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12446 Arg counts are now ptrdiff_t, not size_t.
12447 All variadic functions and their callers changed accordingly.
12448 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12449 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12450 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12451 * callint.c (Fcall_interactively): Check arg count for overflow,
12452 to avoid potential buffer overrun. Use signed char, not 'int',
12453 for 'varies' array, so that we needn't bother to check its size
12454 calculation for overflow.
12455 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12456 * eval.c (apply_lambda):
12457 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12458 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12459 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12461 * callint.c (Fcall_interactively): Don't use index var as event count.
12463 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12464 * mem-limits.h (SIZE): Remove; no longer used.
12466 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12468 Remove unnecessary casts.
12469 * xterm.c (x_term_init):
12470 * xfns.c (x_set_border_pixel):
12471 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12472 These aren't needed now that we assume ANSI C.
12474 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12475 It's more likely to cause problems (due to unsigned overflow)
12478 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12480 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12482 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12484 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12486 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12488 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12490 GLYPH_CODE_FACE returns EMACS_INT, not int.
12491 * dispextern.h (merge_faces):
12492 * xfaces.c (merge_faces):
12493 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12494 Don't assume EMACS_INT fits in int.
12496 * character.h (CHAR_VALID_P): Remove unused parameter.
12497 * fontset.c, lisp.h, xdisp.c: All uses changed.
12499 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12501 * fns.c (concat): Minor tuning based on overflow analysis.
12502 This doesn't fix any bugs. Use int to hold character, instead
12503 of constantly refetching from Emacs object. Use XFASTINT, not
12504 XINT, for value known to be a character. Don't bother comparing
12505 a single byte to 0400, as it's always less.
12507 * floatfns.c (Fexpt):
12508 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12510 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12513 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12515 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12516 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12517 incorrectly succeed when S was a string, because 4294967386 was
12518 truncated before it was used.
12520 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12521 Otherwise, an out-of-range integer could cause undefined behavior
12524 * composite.c: Use int, not EMACS_INT, for characters.
12525 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12526 EMACS_INT, for values that are known to be in character range.
12527 This doesn't fix any bugs but is the usual style inside Emacs and
12528 may generate better code on 32-bit machines.
12530 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12531 This is for reasons similar to the recent CHAR_STRING fix.
12532 * charset.c (Fencode_char): Check that character arg is actually
12533 a character. Pass an int to ENCODE_CHAR.
12534 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12535 wider than 'int', as a compile-time check to prevent future regressions
12538 * character.c (char_string): Remove unnecessary casts.
12540 Make sure a 64-bit char is never passed to CHAR_STRING.
12541 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12542 by silently ignoring the top 32 bits, allowing some values
12543 that were far too large to be valid characters.
12544 * character.h: Include <verify.h>.
12545 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12546 arguments are no wider than unsigned, as a compile-time check
12547 to prevent future regressions in this area.
12549 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12550 (Fsubst_char_in_region):
12552 * xdisp.c (decode_mode_spec_coding):
12553 Adjust to CHAR_STRING's new requirement.
12554 * editfns.c (Finsert_char, Fsubst_char_in_region):
12555 * fns.c (concat): Check that character args are actually
12556 characters. Without this test, these functions did the wrong
12557 thing with wildly out-of-range values on 64-bit hosts.
12559 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12560 These casts should not be needed on 32-bit hosts, either.
12561 * keyboard.c (read_char):
12562 * lread.c (Fload): Remove casts to unsigned.
12564 * lisp.h (UNSIGNED_CMP): New macro.
12565 This fixes comparison bugs on 64-bit hosts.
12566 (ASCII_CHAR_P): Use it.
12567 * casefiddle.c (casify_object):
12568 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
12569 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
12570 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
12571 * dispextern.h (FACE_FROM_ID):
12572 * keyboard.c (read_char): Use UNSIGNED_CMP.
12574 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
12575 not to EMACS_INT, to avoid GCC warning.
12577 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
12579 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
12580 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
12581 isn't needed on 32-bit machines.

13216 instead of using explicit *_CHAR codes.
13217 (bidi_resolve_explicit, bidi_resolve_weak):

13226 (bidi_level_of_next_char): Don't try to lookup the cache for the
13227 next/previous character if nothing is cached there yet, or if we
13228 were just reseat()'ed to a new position.
13230 * xdisp.c (set_cursor_from_row): Set start and stop points
13231 according to the row's direction when priming the loop that looks

13234 (display_prop_intangible_p): Reimplement to call
13235 handle_display_spec instead of single_display_spec_intangible_p.
13236 Accept 3 additional arguments needed by handle_display_spec.
13237 This fixes incorrect cursor motion across display property with complex
13238 values: lists, `(when COND...)' forms, etc.

13240 lists with the argument STRING its top-level element.
13241 (display_prop_string_p): Fix the condition for processing a

13245 (compute_display_string_pos): Accept additional argument
13246 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13247 value of a `display' property is a "replacing spec".
13248 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13249 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13250 the display property, but just return a value indicating whether
13251 the display property will replace the characters it covers.
13252 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13253 frame_window_p members of struct bidi_it.

13277 All callers changed. (Bug#8762)
13279 * gnutls.c: Use Emacs's memory allocators.
13280 Without this change, the gnutls library would invoke malloc etc.
13281 directly, which causes problems on non-SYNC_INPUT hosts, and which
13282 runs afoul of improving memory_full behavior. (Bug#8761)
13283 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13284 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13285 xfree instead of the default malloc, realloc, free.
13286 (Fgnutls_boot): No need to check for memory allocation failure,
13287 since xmalloc does that for us.
13289 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

13310 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13311 * alloc.c (allocate_vectorlike):
13312 Check for overflow in vector size calculations.
13313 * ccl.c (ccl_driver):
13314 Check for overflow when converting EMACS_INT to int.

13316 need to be updated by these changes.
13317 * fns.c (make_hash_table, maybe_resize_hash_table):
13318 Check for integer overflow with large hash tables.
13319 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13320 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13321 (SXHASH_REDUCE): New macro.
13322 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13323 Use it instead of discarding useful hash info with large hash values.
13324 (sxhash_float): New function.
13325 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13326 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13327 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13328 Rewrite to use FIXNUM_BITS, as this simplifies things.
13329 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13330 Adjust signatures to match updated version of code.
13331 (consing_since_gc): Now EMACS_INT, since a single hash table can
13332 use more than INT_MAX bytes.

13381 Make it possible to run ./temacs.
13383 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13384 syms_of_callproc does the same thing. Remove test for

13455 Integer overflow fixes.
13457 * dbusbind.c: Serial number integer overflow fixes.
13458 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13459 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13460 to hold a serial number that is too large for a fixnum.
13461 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13462 Check for serial numbers out of range. Decode any serial number
13463 that was so large that it became a float. (Bug#8722)
13465 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13466 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13467 Use XFASTINT rather than XUINT when numbers are nonnegative.
13468 (xd_append_arg, Fdbus_method_return_internal):
13469 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13470 arguments, check that Lisp number is nonnegative, rather than
13471 silently wrapping negative numbers around. (Bug#8722)
13472 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13475 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13477 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13479 ccl: Add integer overflow checks.
13480 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13481 (IN_INT_RANGE): New macros.
13482 (ccl_driver): Use them to check for integer overflow when
13483 decoding a CCL program. Many of the new checks are whether XINT (x)
13484 fits in int; it doesn't always, on 64-bit hosts. The new version
13485 doesn't catch all possible integer overflows, but it's an
13486 improvement. (Bug#8719)
13488 * alloc.c (make_event_array): Use XINT, not XUINT.
13489 There's no need for unsigned here.
13491 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13492 This follows up to the 2011-05-06 change that substituted uintptr_t
13493 for EMACS_INT. This case wasn't caught back then.
13495 Rework Fformat to avoid integer overflow issues.
13496 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13497 now (part of C89). Include <verify.h>.
13498 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13499 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13500 (Fformat): Avoid the prepass trying to compute sizes; it was only
13501 approximate and thus did not catch overflow reliably. Instead, walk
13502 through the format just once, formatting and computing sizes as we go,
13503 checking for integer overflow at every step, and allocating a larger
13504 buffer as needed. Keep track separately whether the format is
13505 multibyte. Keep only the most-recently calculated precision, rather
13506 than them all. Record whether each argument has been converted to
13507 string. Use EMACS_INT, not int, for byte and char and arg counts.
13508 Support field widths and precisions larger than INT_MAX. Avoid
13509 sprintf's undefined behavior with conversion specifications such as %#d
13510 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13511 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13512 formatting out-of-range floating point numbers with int
13513 formats. (Bug#8668)
13515 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13517 * data.c: Avoid integer truncation in expressions involving floats.
13518 * data.c: Include <intprops.h>.
13519 (arith_driver): When there's an integer overflow in an expression
13520 involving floating point, convert the integers to floating point
13521 so that the resulting value does not suffer from catastrophic
13522 integer truncation. For example, on a 64-bit host (* 4
13523 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13524 Do not rely on undefined behavior after integer overflow.
13526 merge count_size_as_multibyte, parse_str_to_multibyte
13527 * character.c, character.h (count_size_as_multibyte):
13528 Rename from parse_str_to_multibyte; all uses changed.
13529 Check for integer overflow.
13530 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13531 since it's now a duplicate of the other. This is more of
13532 a character than a buffer op, so better that it's in character.c.
13533 * fns.c, print.c: Adjust to above changes.
13535 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13537 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13539 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13541 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13542 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13543 (x_clipboard_manager_save): Now static.
13544 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13546 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13547 (crypto_hash_function): Now static.
13548 Fix pointer signedness problems. Avoid unnecessary initializations.
13550 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13552 * termhooks.h (Vselection_alist): Make it terminal-local.
13554 * terminal.c (create_terminal): Initialize it.
13556 * xselect.c: Support for clipboard managers.
13557 (Vselection_alist): Move to termhooks.h as terminal-local var.
13558 (LOCAL_SELECTION): New macro.
13559 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13560 (symbol_to_x_atom): Remove gratuitous arg.
13561 (x_handle_selection_request, lisp_data_to_selection_data)
13562 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13563 (x_own_selection, x_get_local_selection, x_convert_selection):
13564 New arg, specifying work frame. Use terminal-local Vselection_alist.
13565 (some_frame_on_display): Delete unused function.
13566 (Fx_own_selection_internal, Fx_get_selection_internal)
13567 (Fx_disown_selection_internal, Fx_selection_owner_p)
13568 (Fx_selection_exists_p): New optional frame arg.
13569 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13570 (x_handle_selection_clear): Don't treat other terminals with the
13571 same keyboard specially. Use the terminal-local Vselection_alist.
13572 (x_clear_frame_selections): Use Frun_hook_with_args.
13574 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13576 * xterm.h: Add support for those atoms.
13578 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13580 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13581 (converted_selections, conversion_fail_tag): New global variables.
13582 (x_selection_request_lisp_error): Free the above.
13583 (x_get_local_selection): Remove unnecessary code.
13584 (x_reply_selection_request): Args changed; handle arbitrary array
13585 of converted selections stored in converted_selections.
13586 Separate the XChangeProperty and SelectionNotify steps.
13587 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
13588 (x_convert_selection): New function.
13589 (x_handle_selection_event): Simplify.
13590 (x_get_foreign_selection): Don't ignore incoming requests while
13591 waiting for an answer; this will fail when we implement
13592 SAVE_TARGETS, and seems unnecessary anyway.
13593 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
13594 (Vx_sent_selection_functions): Doc fix.
13596 2011-05-26 Leo Liu <sdl.web@gmail.com>
13598 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
13600 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13602 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
13604 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
13605 for fringe update if it has periodic bitmap.
13606 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
13607 and fringe_bitmap_periodic_p.
13609 * fringe.c (get_fringe_bitmap_data): New function.
13610 (draw_fringe_bitmap_1, update_window_fringes): Use it.
13611 (update_window_fringes): Record periodicity of fringe bitmap in glyph
13612 row. Mark glyph row for fringe update if periodicity changed.
13614 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
13615 for fringe update unless it has periodic bitmap.
13617 2011-05-25 Kenichi Handa <handa@m17n.org>
13619 * xdisp.c (get_next_display_element): Set correct it->face_id for
13620 a static composition.
13622 2011-05-24 Leo Liu <sdl.web@gmail.com>
13625 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
13627 * fns.c (crypto_hash_function, Fsha1): New function.
13628 (Fmd5): Use crypto_hash_function.
13629 (syms_of_fns): Add Ssha1.
13631 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13633 * gnutls.c: Remove unused macros.
13634 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
13635 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
13636 Remove macros that are defined and never used.
13637 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
13639 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13641 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
13642 (Fx_get_selection_internal): Minor cleanup.
13643 (Fx_own_selection_internal): Rename arguments for consistency with
13646 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13648 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
13650 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13652 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
13654 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13656 * dispnew.c (scrolling_window): Don't exclude the case that the
13657 last enabled row in the desired matrix touches the bottom boundary.
13659 2011-05-21 Glenn Morris <rgm@gnu.org>
13661 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
13662 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
13663 and add some more files.
13665 2011-05-20 Eli Zaretskii <eliz@gnu.org>
13667 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
13668 report_file_error introduced by the change from 2011-05-07.
13670 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
13672 * systime.h (Time): Define only if emacs is defined.
13673 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
13674 where the include path doesn't have X11/X.h by default. See
13675 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
13677 2011-05-20 Kenichi Handa <handa@m17n.org>
13679 * composite.c (find_automatic_composition): Fix previous change.
13681 2011-05-20 Glenn Morris <rgm@gnu.org>
13683 * lisp.mk: New file, split from Makefile.in.
13684 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
13685 (shortlisp): Remove.
13686 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
13688 2011-05-19 Glenn Morris <rgm@gnu.org>
13690 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
13691 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
13692 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
13693 (lisp): Set the order to that of loadup.el.
13694 (shortlisp): Make it a copy of $lisp.
13695 (SOME_MACHINE_LISP): Remove.
13696 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
13697 Use just $shortlisp, not $SOME_MACHINE_LISP too.
13699 2011-05-18 Kenichi Handa <handa@m17n.org>
13701 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
13702 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
13703 (find_automatic_composition): Mostly rewrite for efficiency.
13705 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
13707 * makefile.w32-in: Update dependencies.
13709 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
13711 * menu.c: Include limits.h (fixes the MS-Windows build broken by
13712 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
13714 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
13716 Fix some integer overflow issues, such as string length overflow.
13718 * insdel.c (count_size_as_multibyte): Check for string overflow.
13720 * character.c (lisp_string_width): Check for string overflow.
13721 Use EMACS_INT, not int, for string indexes and lengths; in
13722 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
13723 the resulting string length overflows an EMACS_INT; instead,
13724 report a string overflow if no precision given. When checking for
13725 precision exhaustion, use a check that cannot possibly have
13726 integer overflow. (Bug#8675)
13727 * character.h (lisp_string_width): Adjust to new signature.
13729 * alloc.c (string_overflow): New function.
13730 (Fmake_string): Use it. This doesn't change behavior, but saves
13731 a few bytes and will simplify future changes.
13732 * character.c (string_escape_byte8): Likewise.
13733 * lisp.h (string_overflow): New decl.
13735 Fixups, following up to the user-interface timestamp change.
13736 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
13737 for UI timestamps, instead of unsigned long.
13738 * msdos.c (mouse_get_pos): Likewise.
13739 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
13740 * w32gui.h (Time): Define by including "systime.h" rather than by
13741 declaring it ourselves. (Bug#8664)
13743 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
13744 * image.c (clear_image_cache): Likewise.
13746 * term.c (term_mouse_position): Don't assume time_t wraparound.
13748 Be more systematic about user-interface timestamps.
13749 Before, the code sometimes used 'Time', sometimes 'unsigned long',
13750 and sometimes 'EMACS_UINT', to represent these timestamps.
13751 This change causes it to use 'Time' uniformly, as that's what X uses.
13752 This makes the code easier to follow, and makes it easier to catch
13753 integer overflow bugs such as Bug#8664.
13754 * frame.c (Fmouse_position, Fmouse_pixel_position):
13755 Use Time, not unsigned long, for user-interface timestamps.
13756 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
13757 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
13758 * keyboard.h (last_event_timestamp): Likewise.
13759 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
13760 * menu.h (xmenu_show): Likewise.
13761 * term.c (term_mouse_position): Likewise.
13762 * termhooks.h (struct input_event.timestamp): Likewise.
13763 (struct terminal.mouse_position_hook): Likewise.
13764 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
13765 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
13766 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
13767 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
13768 what it was before.
13769 * menu.h, termhooks.h: Include "systime.h", for Time.
13771 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
13772 Don't assume that the difference between two unsigned long values
13773 can fit into an integer. At this point, we know button_down_time
13774 <= event->timestamp, so the difference must be nonnegative, so
13775 there's no need to cast the result if double-click-time is
13776 nonnegative, as it should be; check that it's nonnegative, just in
13777 case. This bug is triggered when events are more than 2**31 ms
13778 apart (about 25 days). (Bug#8664)
13780 * xselect.c (last_event_timestamp): Remove duplicate decl.
13781 (x_own_selection): Remove needless cast to unsigned long.
13783 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
13784 that always fit in int. Use a sentinel instead of a counter, to
13785 avoid a temp and to allay GCC's concerns about possible int overflow.
13786 * frame.h (struct frame): Use int for menu_bar_items_used
13787 instead of EMACS_INT, since it always fits in int.
13789 * menu.c (grow_menu_items): Check for int overflow.
13791 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
13793 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
13794 Before, the code was not consistent. These values cannot exceed
13795 2**31 - 1 so there's no need to make them unsigned.
13796 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
13797 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
13798 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
13800 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
13802 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
13803 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
13804 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
13805 presumably because the widths might not match.
13807 * window.c (size_window): Avoid needless test at loop start.
13809 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
13811 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
13813 2011-05-12 Drew Adams <drew.adams@oracle.com>
13815 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
13817 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13819 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
13820 `width' to `bar_area_x' and `bar_area_width', respectively.
13821 (x_scroll_run): Take account of fringe background extension.
13823 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
13824 Rename local vars `left' and `width' to `bar_area_x' and
13825 `bar_area_width', respectively.
13826 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
13827 background extension.
13829 2011-05-10 Jim Meyering <meyering@redhat.com>
13831 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
13833 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
13835 * image.c (Finit_image_library): Return t for built-in image types,
13836 like pbm and xbm. (Bug#8640)
13838 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
13840 * w32menu.c (set_frame_menubar): Fix submenu allocation.
13842 2011-05-07 Eli Zaretskii <eliz@gnu.org>
13844 * w32console.c (Fset_screen_color): Doc fix.
13845 (Fget_screen_color): New function.
13846 (syms_of_ntterm): Defsubr it.
13848 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
13849 unlink the temporary file if Fcall_process didn't create it in the
13851 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
13852 child process will be redirected to a file specified with `:file'.
13853 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
13854 cue to call_process_cleanup not to close that handle.
13856 2011-05-07 Ben Key <bkey76@gmail.com>
13858 * makefile.w32-in: The bootstrap-temacs rule now makes use of
13859 one of two shell specific rules, either bootstrap-temacs-CMD or
13860 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
13861 to the previous implementation of the bootstrap-temacs rule.
13862 The bootstrap-temacs-CMD rule is similar to the previous
13863 implementation of the bootstrap-temacs rule except that it
13864 makes use of the ESC_CFLAGS variable instead of the CFLAGS
13867 These changes, along with some changes to nt/configure.bat,
13868 nt/gmake.defs, and nt/nmake.defs, are required to extend my
13869 earlier fix to add support for --cflags and --ldflags options
13870 that include quotes so that it works whether make uses cmd or
13873 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
13875 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
13876 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
13878 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
13879 a string. Handle both cases.
13880 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
13881 (Fdbus_register_method): Use Qinvalid_function.
13883 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
13885 * makefile.w32-in: Update dependencies.
13886 (LISP_H): Add inttypes.h and stdin.h.
13887 (PROCESS_H): Add unistd.h.
13889 2011-05-06 Eli Zaretskii <eliz@gnu.org>
13891 * lread.c: Include limits.h (fixes the MS-Windows build broken by
13892 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
13894 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
13896 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
13898 * term.c (vfatal): Remove stray call to va_end.
13899 It's not needed and the C Standard doesn't allow it here anyway.
13901 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
13902 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
13904 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
13907 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
13909 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13911 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
13913 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
13915 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
13917 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
13918 * charset.c (Fdefine_charset_internal): Don't initialize
13919 charset.code_space[15]. The value was garbage, on hosts with
13920 32-bit int (Bug#8600).
13922 * lread.c (read_integer): Be more consistent with string-to-number.
13923 Use string_to_number to do the actual conversion; this avoids
13924 rounding errors and fixes some other screwups. Without this fix,
13925 for example, #x1fffffffffffffff was misread as -2305843009213693952.
13926 (digit_to_number): Move earlier, for benefit of read_integer.
13927 Return -1 if the digit is out of range for the base, -2 if it is
13928 not a digit in any supported base. (Bug#8602)
13930 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13932 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13933 to match comment at start of function. This also removes a
13934 GCC warning about overflow in a 32+64-bit port.
13936 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
13938 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
13939 Reported by Stefan Monnier in
13940 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
13941 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13942 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
13944 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
13945 (EMACS_UINTPTR): Likewise, with uintptr_t.
13947 * lisp.h: Prefer 64-bit EMACS_INT if available.
13948 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
13949 on 32-bit hosts that have 64-bit int, so that they can access
13951 However, temporarily disable this change unless the temporary
13952 symbol WIDE_EMACS_INT is defined.
13954 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
13956 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
13957 This removes an assumption that EMACS_INT and long are the same
13958 width as pointers. The assumption is true for Emacs porting targets
13959 now, but we want to make other targets possible.
13960 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
13961 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
13962 In the rest of the code, change types of integers that hold casted
13963 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
13964 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
13965 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
13966 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
13967 No need to cast type when ORing.
13968 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
13969 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
13970 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
13971 assume EMACS_INT is the same width as char *.
13972 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
13973 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
13974 Remove no-longer-needed casts.
13975 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
13976 (xg_tool_bar_help_callback, xg_make_tool_item):
13977 Use EMACS_INTPTR to hold an integer
13978 that will be cast to void *; this can avoid a GCC warning
13979 if EMACS_INT is not the same width as void *.
13980 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
13981 * xdisp.c (display_echo_area_1, resize_mini_window_1):
13982 (current_message_1, set_message_1):
13983 Use a local to convert to proper width without a cast.
13984 * xmenu.c (dialog_selection_callback): Likewise.
13986 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
13987 Also, don't assume VALBITS / RAND_BITS is less than 5,
13988 and don't rely on undefined behavior when shifting a 1 left into
13990 * lisp.h (get_random): Change signature to match.
13992 * lread.c (hash_string): Use size_t, not int, for hash computation.
13993 Normally we prefer signed values; but hashing is special, because
13994 it's better to use unsigned division on hash table sizes so that
13995 the remainder is nonnegative. Also, size_t is the natural width
13996 for hashing into memory. The previous code used 'int', which doesn't
13997 retain enough info to hash well into very large tables.
13998 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14000 * dbusbind.c: Don't possibly lose pointer info when converting.
14001 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14002 Use XPNTR rather than XHASH, so that the high-order bits of
14003 the pointer aren't lost when converting through void *.
14005 * eval.c (Fautoload): Don't double-shift a pointer.
14007 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14009 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14011 * gnutls.c (DEF_GNUTLS_FN):
14012 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14014 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14016 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14019 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14021 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14022 New version that can reserve upto 2GB of heap space.
14024 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14026 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14028 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14030 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14031 `gnutls_certificate_set_x509_key_file'.
14033 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14035 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14036 Update dependencies.
14038 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14040 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14041 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14042 Remove unused parameter `fildes'.
14043 * process.c (read_process_output, send_process): Don't pass it.
14045 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14047 Fix previous change: the library cache is defined in w32.c.
14048 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14049 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14051 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14053 Implement dynamic loading of GnuTLS on Windows.
14055 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14056 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14057 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14060 * gnutls.c (Qgnutls_dll): Define.
14061 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14062 (gnutls_*): Declare function pointers.
14063 (init_gnutls_functions): New function to initialize function pointers.

14066 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14067 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14068 (emacs_gnutls_write, emacs_gnutls_read)
14069 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14070 (Fgnutls_available_p): New function.
14071 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14072 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.

14081 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14083 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14084 (w32_delayed_load): Move from image.c. When loading a library, record
14085 its filename in the :loaded-from property of the library id.
14086 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14087 Initialize and staticpro them.
14088 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14090 * process.c: Include lisp.h before w32.h, not after.
14091 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14092 instead of gnutls_record_check_pending.
14094 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14096 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14098 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14099 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14102 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14104 * xterm.c (x_set_frame_alpha): Do not set property on anything
14105 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14107 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14109 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14111 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14113 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14127 * sysdep.c (wait_for_termination_1): Make static.
14128 (wait_for_termination, interruptible_wait_for_termination):
14129 Move after wait_for_termination_1.
14131 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14133 * sysdep.c (interruptible_wait_for_termination): New function
14134 which is like wait_for_termination, but allows keyboard
14137 * callproc.c (Fcall_process): Add (:file "file") as an option for
14139 (Fcall_process_region): Ditto.
14141 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14143 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14144 rather than `XVECTOR (FOO)->size'.
14146 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14147 inttypes.h, as a gnulib replacement is used if it not available in
14150 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14152 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14153 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14154 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14156 * coding.c (coding_alloc_by_realloc): Error out if destination
14157 will grow beyond MOST_POSITIVE_FIXNUM.
14158 (decode_coding_emacs_mule): Abort if there isn't enough place in
14159 charbuf for the composition carryover bytes. Reserve an extra
14160 space for up to 2 characters produced in a loop.
14161 (decode_coding_iso_2022): Abort if there isn't enough place in
14162 charbuf for the composition carryover bytes.
14164 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14166 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
14167 aborting when %lld or %lll format is passed.
14168 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14169 %llo or %llx format is passed. (Bug#8545)
14171 * window.c (window_scroll_line_based): Use a marker instead of
14172 simple variables to record original value of point. (Bug#7952)
14174 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14175 produced by %s or %c overflows available buffer space. (Bug#8545)
14177 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14179 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

14188 * keyboard.c (Qdelayed_warnings_hook): Define.
14189 (command_loop_1): Run `delayed-warnings-hook'
14190 if Vdelayed_warnings_list is non-nil.
14191 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.

14194 2011-04-28 Eli Zaretskii <eliz@gnu.org>
14196 * doprnt.c (doprnt): Don't return value smaller than the buffer
14197 size if the message was truncated. (Bug#8545).
14199 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14201 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

14208 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14210 * makefile.w32-in: Update dependencies.
14212 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14214 Improve `doprnt' and its usage. (Bug#8545)
14215 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14216 `format_end'. Remove support for %l as a conversion specifier.
14217 Don't use xrealloc. Improve diagnostics when the %l size modifier
14218 is used. Update the commentary.
14220 * eval.c (verror): Simplify calculation of size_t.
14222 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14225 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14227 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14230 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14232 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14233 This makes this file independent of the recent pseudovector change.
14235 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14237 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14239 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14240 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14241 Remove unused local.
14242 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14244 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14245 GCC 4.6.0 optimizes based on type-based alias analysis.
14246 For example, if b is of type struct buffer * and v of type struct
14247 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14248 != &v->size, and therefore "v->size = 1; b->size = 2; return
14249 v->size;" must therefore return 1. This assumption is incorrect
14250 for Emacs, since it type-puns struct Lisp_Vector * with many other
14251 types. To fix this problem, this patch adds a new type struct
14252 vectorlike_header that documents the constraints on layout of vectors
14253 and pseudovectors, and helps optimizing compilers not get fooled
14254 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14255 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14256 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14258 (XSETPVECTYPE): Rewrite in terms of new macro.
14259 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14260 This is a bit clearer, and further avoids the possibility of
14261 undesirable aliasing.
14262 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14263 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14264 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14265 since Lisp_Subr is a special case (no "next" field).
14266 (ASIZE): Now uses header.size rather than size.
14267 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14268 to avoid the hassle of writing XVECTOR (foo)->header.size.
14269 (struct vectorlike_header): New type.
14270 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14271 object, to help avoid aliasing.
14272 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14273 (SUBRP): Likewise, since Lisp_Subr is a special case.
14274 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14275 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14276 (struct Lisp_Hash_Table): Combine first two members into a single
14277 struct vectorlike_header member. All uses of "size" and "next" members
14278 changed to be "header.size" and "header.next".
14279 * buffer.h (struct buffer): Likewise.
14280 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14281 * frame.h (struct frame): Likewise.
14282 * process.h (struct Lisp_Process): Likewise.
14283 * termhooks.h (struct terminal): Likewise.
14284 * window.c (struct save_window_data, struct saved_window): Likewise.
14285 * window.h (struct window): Likewise.
14286 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14287 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14288 * buffer.c (init_buffer_once): Likewise.
14289 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14291 * process.c (Fformat_network_address): Use local var for size,
14294 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14296 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14297 * data.c (atof): Remove decl; no longer used or needed.
14298 (digit_to_number): Move to lread.c.
14299 (Fstring_to_number): Use new string_to_number function, to be
14300 consistent with how the Lisp reader treats infinities and NaNs.
14301 Do not assume that floating-point numbers represent EMACS_INT
14302 without losing information; this is not true on most 64-bit hosts.
14303 Avoid double-rounding errors, by insisting on integers when
14304 parsing non-base-10 numbers, as the documentation specifies.
14305 * lisp.h (string_to_number): New decl, replacing ...
14306 (isfloat_string): Remove.
14307 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14308 (read1): Do not accept +. and -. as integers; this
14309 appears to have been a coding error. Similarly, do not accept
14310 strings like +-1e0 as floating point numbers. Do not report
14311 overflow for integer overflows unless the base is not 10 which
14312 means we have no simple and reliable way to continue.
14313 Break out the floating-point parsing into a new
14314 function string_to_number, so that Fstring_to_number parses
14315 floating point numbers consistently with the Lisp reader.
14316 (digit_to_number): Move here from data.c. Make it static inline.
14317 (E_CHAR, EXP_INT): Remove, replacing with ...
14318 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14319 (string_to_number): New function, replacing isfloat_string.
14320 This function checks for valid syntax and produces the resulting
14321 Lisp float number too. Rework it so that string-to-number
14322 no longer mishandles examples like "1.0e+". Use strtoumax,
14323 so that overflow for non-base-10 numbers is reported only when
14324 there's no portable and simple way to convert to floating point.
14326 * textprop.c (set_text_properties_1): Rewrite for clarity,
14327 and to avoid GCC warning about integer overflow.
14329 * intervals.h (struct interval): Use EMACS_INT for members
14330 where EMACS_UINT might cause problems. See
14331 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14332 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14333 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14335 (offset_intervals): Tell GCC not to worry about length overflow
14336 when negating a negative length.
14338 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14339 (overrun_check_free): Likewise.
14341 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14342 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14345 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14346 (gnutls_make_error): Rename local to avoid shadowing.
14347 (gnutls_emacs_global_deinit): ifdef out; not used.
14348 (Fgnutls_boot): Use const for pointer to readonly storage.
14349 Comment out unused local. Fix pointer signedness problems.
14351 * lread.c (openp): Don't stuff size_t into an 'int'.
14352 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14353 about possible signed overflow.
14355 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14356 (GDK_KEY_g): Don't define if already defined.
14357 (xg_prepare_tooltip): Avoid pointer signedness problem.
14358 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14360 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14361 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14363 * xfns.c (Fx_window_property): Simplify a bit,
14364 to make a bit faster and to avoid GCC 4.6.0 warning.
14365 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14367 * fns.c (internal_equal): Don't assume size_t fits in int.
14369 * alloc.c (compact_small_strings): Tighten assertion a little.
14371 Replace pEd with more-general pI, and fix some printf arg casts.
14372 * lisp.h (pI): New macro, generalizing old pEd macro to other
14373 conversion specifiers. For example, use "...%"pI"d..." rather
14374 than "...%"pEd"...".
14375 (pEd): Remove. All uses replaced with similar uses of pI.
14376 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14377 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14378 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14379 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14380 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14381 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14382 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14384 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14385 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14386 * print.c (safe_debug_print, print_object): Likewise.
14387 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14389 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14390 avoiding the 0 flag, which is not portable.
14391 * process.c (Fmake_network_process): Use pI to avoid cast.
14392 * region-cache.c (pp_cache): Likewise.
14393 * xdisp.c (decode_mode_spec): Likewise.
14394 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14395 behavior on 64-bit hosts with printf arg.
14396 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14397 (x_stop_queuing_selection_requests): Likewise.
14398 (x_get_window_property): Don't truncate byte count to an 'int'
14401 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14402 here, since it parses constructs like leading '-' and spaces,
14403 which are not wanted; and it overflows with large numbers.
14404 Instead, simply match F[0-9]+, which is what is wanted anyway.
14406 * alloc.c: Remove unportable assumptions about struct layout.
14407 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14408 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14409 (allocate_vectorlike, make_pure_vector): Use the new macros,
14410 plus offsetof, to remove unportable assumptions about struct layout.
14411 These assumptions hold on all porting targets that I know of, but
14412 they are not guaranteed, they're easy to remove, and removing them
14413 makes further changes easier.
14415 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14416 This doesn't fix a bug but makes the code clearer.
14417 (string_overrun_cookie): Now const. Use initializers that
14418 don't formally overflow signed char, to avoid warnings.
14419 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14420 can cause Emacs to crash when string overrun checking is enabled.
14421 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14422 multiple of sizeof (EMACS_INT); it need not be, if
14423 alignof(EMACS_INT) < sizeof (EMACS_INT).
14424 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14426 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14433 supposed to be handshaking. (Bug#8556)
14434 Reported by Paul Eggert <eggert@cs.ucla.edu>.

14453 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14455 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14456 "cast to pointer from integer of different size".
14458 Improve doprnt and its use in verror. (Bug#8545)
14459 * doprnt.c (doprnt): Document the set of format control sequences
14460 supported by the function. Use SAFE_ALLOCA instead of always
14463 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14464 is one byte too soon. Don't use xrealloc; instead xfree and
14467 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14469 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14472 * gnutls.c: Renamed global_initialized to
14473 gnutls_global_initialized. Added internals for the
14474 :verify-hostname-error, :verify-error, and :verify-flags
14475 parameters of `gnutls-boot' and documented those parameters in the
14476 docstring. Start callback support.
14477 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14478 unless a fatal error occurred. Call gnutls_alert_send_appropriate

14552 (SIZE_MAX): New macro.
14553 (doprnt): Return a size_t value. 2nd arg is now size_t.
14554 Many local variables are now size_t instead of int or unsigned.
14555 Improve overflow protection. Support `l' modifier for integer
14556 conversions. Support %l conversion. Don't assume an EMACS_INT
14557 argument for integer conversions and for %c.
14559 * lisp.h (doprnt): Restore prototype.
14561 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
14562 $(SRC)/character.h.
14564 * Makefile.in (base_obj): Add back doprnt.o.
14566 * deps.mk (doprnt.o): Add back prerequisites.

14576 * callint.c (Fcall_interactively): When displaying error message
14577 about invalid control letter, pass the character's codepoint, not
14578 a pointer to its multibyte form. Improve display of the character
14579 in octal and display also its hex code.
14581 * character.c (char_string): Use %x to display the (unsigned)
14582 codepoint of an invalid character, to avoid displaying a bogus
14585 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
14586 `error', not SYMBOL_NAME itself.
14588 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

14591 * charset.c (check_iso_charset_parameter): Fix incorrect argument
14592 to `error' in error message about FINAL_CHAR argument. Make sure
14593 FINAL_CHAR is a character, and use %c when it is passed as

14658 Define only if needed.
14660 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
14661 by pacifying GCC about it. Maybe it's time to retire it?

14664 * dispextern.h (struct redisplay_interface): Rename param
14665 to avoid shadowing.
14666 * termhooks.h (struct terminal): Likewise.
14667 * xterm.c (xembed_send_message): Likewise.
14669 * insdel.c (make_gap_smaller): Define only if
14670 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
14672 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
14675 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
14676 so that we aren't warned about unused symbols.
14678 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.

14693 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
14695 * xmenu.c (menu_help_callback): Pointer type fixes.

14713 compatible char. Avoid the old compiler warnings about
14714 out-of-range initializers by using, for example, '\xab' rather
14717 * xgselect.c (xgselect_initialize): Check vs interface
14718 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

14783 * nsfont.m: Fixed bugs in ns_get_family and
14784 ns_descriptor_to_entity that were caused by using free to
14785 deallocate memory blocks that were allocated by xmalloc (via
14786 xstrdup). This caused Emacs to crash when compiled with
14787 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
14788 --enable-checking=xmallocoverrun). xfree is now used to
14789 deallocate these memory blocks.

14807 * process.c (send_process): Adjust to the new signatures of
14808 emacs_write and emacs_gnutls_write. Do not attempt to store

15199 so that it can be used in other C modules, use the new macro DEFUE.
15200 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15201 (Finit_image_library):
15202 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15203 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15204 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15205 Remove decls, since these functions are now static.
15206 (Funintern, Fget_internal_run_time): New decls, since these functions
15207 were already external.
15209 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15210 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

15213 * keyboard.c, keymap.c, lread.c:
15214 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15215 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15216 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15217 Mark functions with DEFUE instead of DEFUN,
15218 if they are used in other modules.
15219 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15220 decls for now-static functions.
15221 * buffer.h (Fdelete_overlay): Remove decl.
15222 * callproc.c (Fgetenv_internal): Mark as internal.
15223 * composite.c (Fremove_list_of_text_properties): Remove decl.

15229 (Funintern): Remove extern decl; now in .h file where it belongs.
15230 * fileio.c (Fmake_symbolic_link): New forward static decl.
15231 * image.c (Finit_image_library): New forward static decl.
15232 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

15257 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15259 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15260 when at ZV. (Bug#8487)
15262 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15264 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15266 * keyboard.c (parse_tool_bar_item): Likewise.
15267 * sound.c (sound_cleanup, alsa_close): Likewise.
15268 * termcap.c (tgetent): Likewise.
15269 * xfns.c (x_default_font_parameter): Likewise.
15270 * xsettings.c (read_and_apply_settings): Likewise.
15272 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15273 (overrun_check_free): Protoize.
15275 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15277 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15278 since callers should never pass a negative size.
15279 Change the signature to match that of plain 'read' and 'write'; see
15280 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15281 * lisp.h: Update prototypes of emacs_write and emacs_read.
15283 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15285 * xdisp.c (redisplay_window): Don't try to determine the character
15286 position of the scroll margin if the window start point w->startp
15287 is outside the buffer's accessible region. (Bug#8468)
15289 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15291 Fix write-region and its subroutines for buffers > 2GB.
15292 * fileio.c (a_write, e_write): Modify declaration of arguments and
15293 local variables to support buffers larger than 2GB.
15294 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15296 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15297 argument, local variables, and return value.
15299 * lisp.h: Update prototypes of emacs_write and emacs_read.
15301 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15303 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15305 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15307 Fix more problems found by GCC 4.6.0's static checks.
15309 * xdisp.c (vmessage): Use a better test for character truncation.
15311 * charset.c (load_charset_map): <, not <=, for optimization,
15312 and to avoid potential problems with integer overflow.
15313 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15314 * casetab.c (set_identity, shuffle): Likewise.
15315 * editfns.c (Fformat): Likewise.
15316 * syntax.c (skip_chars): Likewise.
15318 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15319 This also lets GCC 4.6.0 generate slightly better loop code.
15321 * callint.c (Fcall_interactively): <, not <=, for optimization.
15322 (Fcall_interactively): Count the number of arguments produced,
15323 not the number of arguments given. This is simpler and lets GCC
15324 4.6.0 generate slightly better code.
15326 * ftfont.c: Distingish more carefully between FcChar8 and char.
15327 The previous code passed unsigned char * to a functions like
15328 strlen and xstrcasecmp that expect char *, which does not
15329 conform to the C standard.
15330 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15331 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15332 char * when the C standard requires it.
15334 * keyboard.c (read_char): Remove unused var.
15336 * eval.c: Port to Windows vsnprintf (Bug#8435).
15337 Include <limits.h>.
15338 (SIZE_MAX): Define if the headers do not.
15339 (verror): Do not give up if vsnprintf returns a negative count.
15340 Instead, grow the buffer. This ports to Windows vsnprintf, which
15341 does not conform to C99. Problem reported by Eli Zaretskii.
15342 Also, simplify the allocation scheme, by avoiding the need for
15343 calling realloc, and removing the ALLOCATED variable.
15345 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15347 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15348 But keep the doprint source code for now, as we might revamp it
15349 and use it again (Bug#8435).
15350 * lisp.h (doprnt): Remove.
15351 * Makefile.in (base_obj): Remove doprnt.o.
15352 * deps.mk (doprnt.o): Remove.
15354 error: Print 32- and 64-bit integers portably (Bug#8435).
15355 Without this change, on typical 64-bit hosts error ("...%d...", N)
15356 was used to print both 32- and 64-bit integers N, which relied on
15357 undefined behavior.
15358 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15359 * lisp.h (error, verror): Mark as printf-like functions.
15360 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15361 Report overflow in size calculations when allocating printf buffer.
15362 Do not truncate output string at its first null byte.
15363 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15364 Truncate the output at a character boundary, since vsnprintf does not
15366 * charset.c (check_iso_charset_parameter): Convert internal
15367 character to string before calling 'error', since %c now has the
15369 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15370 overflow when computing char to be passed to 'error'. Do not
15371 pass Lisp_Object to 'error'; pass the integer instead.
15372 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15373 formatted with plain %d.
15375 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15377 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15379 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15381 * xterm.c (x_catch_errors): Remove duplicate declaration.
15383 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15385 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15387 2011-04-10 Jim Meyering <meyering@redhat.com>
15389 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15390 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15391 return ssize_t not "int", and use size_t as the buffer length.
15392 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15393 * gnutls.h: Update declarations.
15394 * process.c (read_process_output): Use ssize_t, to match.
15395 (send_process): Likewise.
15397 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15399 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15401 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15403 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15404 Use unsigned char, to match FcChar8 type definition.
15406 * xterm.c (handle_one_xevent):
15407 * xmenu.c (create_and_show_popup_menu):
15408 * xselect.c (x_decline_selection_request)
15409 (x_reply_selection_request): Avoid type-punned deref of X events.
15411 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15413 Fix some uses of `int' instead of EMACS_INT.
15414 * search.c (string_match_1, fast_string_match)
15415 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15416 (scan_buffer, find_next_newline_no_quit)
15417 (find_before_next_newline, search_command, Freplace_match)
15418 (Fmatch_data): Make some `int' variables be EMACS_INT.
15420 * xdisp.c (display_count_lines): 3rd argument and return value now
15421 EMACS_INT. All callers changed.
15422 (pint2hrstr): Last argument is now EMACS_INT.
15424 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15425 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15426 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15427 (decode_coding_utf_16, decode_coding_emacs_mule)
15428 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15429 (decode_coding_ccl, decode_coding_charset)
15430 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15431 (decode_coding_iso_2022, decode_coding_emacs_mule)
15432 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15433 <char_offset, last_offset>: Declare EMACS_INT.

15435 (encode_coding_emacs_mule, encode_invocation_designation)
15436 (encode_designation_at_bol, encode_coding_iso_2022)
15437 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15438 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15440 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15441 (encode_invocation_designation): Last argument P_NCHARS is now
15443 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15444 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15446 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15449 * ccl.c (Fccl_execute_on_string): Declare some variables
15452 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15454 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15456 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15458 * process.c (Fformat_network_address): Doc fix.
15460 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15462 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15464 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15466 * keyboard.c (read_char): Call Lisp function help-form-show,
15467 instead of using internal_with_output_to_temp_buffer.
15468 (Qhelp_form_show): New var.
15469 (syms_of_keyboard): Use DEFSYM macro.
15471 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15473 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15475 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15477 * process.c (Flist_processes): Remove to Lisp.

15480 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15482 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15484 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15486 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15488 Fix more problems found by GCC 4.6.0's static checks.

15494 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15496 * xdisp.c (vmessage): Mark as a printf-like function.
15498 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

15505 to system-supplied API.
15507 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15509 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15510 This avoids several warnings with gcc -Wstrict-overflow.
15511 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15512 directly, rather than having caller test rule sign. This avoids
15513 some unnecessary tests.
15514 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15515 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15516 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15518 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15519 (xfont_open): Avoid unnecessary tests.
15521 * composite.c (composition_gstring_put_cache): Use unsigned integer.
15523 * composite.h, composite.c (composition_gstring_put_cache):
15524 Use EMACS_INT, not int, for length.

15530 by using the new macro.
15532 * textprop.c (set_text_properties_1): Change while to do-while,
15533 since the condition is always true at first.
15535 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15536 (interval_deletion_adjustment): Return unsigned value.
15539 * process.c (list_processes_1, create_pty, read_process_output):

15549 (update_syntax_table): Use unsigned instead of int.
15551 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
15552 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15553 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
15555 * print.c (print_error_message): Avoid int overflow.
15557 * font.c (font_list_entities): Redo for clarity,
15558 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15560 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15561 (font_score): Avoid potential overflow in diff calculation.
15563 * fns.c (substring_both): Remove var that is set but not used.
15564 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15566 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15568 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15569 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15570 can always succeed if overflow has undefined behavior.
15572 * search.c (boyer_moore, wordify): Remove vars set but not used.
15573 (wordify): Omit three unnecessary tests.
15575 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15576 All callers changed. This avoids the need for an unused var.
15578 * casefiddle.c (casify_region): Remove var that is set but not used.
15580 * dired.c (file_name_completion): Remove var that is set but not used.
15582 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
15584 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
15585 (Finsert_file_contents): Remove unnecessary code checking fd.
15587 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
15588 Check for integer overflow on size calculations.
15590 * buffer.c (Fprevious_overlay_change): Remove var that is set
15593 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
15594 Remove vars that are set but not used.
15595 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
15596 (timer_check_2): Mark vars as initialized.
15598 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
15600 * image.c (lookup_image): Remove var that is set but not used.
15601 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
15603 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
15604 that are set but not used.
15606 * xfns.c (make_invisible_cursor): Don't return garbage
15607 if XCreateBitmapFromData fails (Bug#8410).
15609 * xselect.c (x_get_local_selection, x_handle_property_notify):
15610 Remove vars that are set but not used.
15612 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
15613 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
15615 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
15616 Remove var that is set but not used.

15618 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
15619 Check for overflow.
15621 * xfaces.c (realize_named_face): Remove vars that are set but not used.
15622 (map_tty_color) [!defined MSDOS]: Likewise.
15624 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
15626 * coding.c: Remove vars that are set but not used.
15627 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
15628 All callers changed.
15629 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
15630 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
15631 (decode_coding_charset): Remove vars that are set but not used.
15633 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
15634 that is set but not used.
15636 * print.c (print_object): Remove var that is set but not used.
15638 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
15639 The gnulib version avoids calling malloc in the usual case,
15640 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
15641 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
15642 * filelock.c (current_lock_owner): Likewise.
15643 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

15645 (emacs_no_realloc_allocator): New static constant.
15646 (emacs_readlink): New function.
15647 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

15674 do not dereference NULL upon failed strdup
15675 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
15676 (ns_get_family): Likewise.
15678 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

15682 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
15684 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
15687 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
15689 Add lexical binding.

15700 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
15702 (syms_of_lread): Declare `lexical-binding'.
15704 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
15706 * keyboard.c (eval_dyn): New fun.
15707 (menu_item_eval_property): Use it.
15709 * image.c (parse_image_spec): Use Ffunctionp.
15711 * fns.c (concat, mapcar1): Accept byte-code-functions.
15713 * eval.c (Fsetq): Handle lexical vars.
15714 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
15715 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
15716 (FletX, Flet): Obey lexical binding.
15717 (Fcommandp): Handle closures.
15718 (Feval): New `lexical' arg.
15719 (eval_sub): New function extracted from Feval. Use it almost
15720 everywhere where Feval was used. Look up vars in lexical env.
15722 (Ffunctionp): Move from subr.el.
15723 (Ffuncall): Handle closures.
15724 (apply_lambda): Remove `eval_flags'.
15725 (funcall_lambda): Handle closures and new byte-code-functions.
15726 (Fspecial_variable_p): New function.
15727 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
15728 but without exporting it to Lisp.
15730 * doc.c (Fdocumentation, store_function_docstring):
15731 * data.c (Finteractive_form): Handle closures.
15733 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
15736 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
15738 (exec_byte_code): New function extracted from Fbyte_code to handle new
15739 calling convention for byte-code-functions. Add new byte-codes.
15741 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

15747 * xdisp.c (redisplay_internal): Fix prototype.
15749 2011-03-31 Eli Zaretskii <eliz@gnu.org>
15751 * xdisp.c (SCROLL_LIMIT): New macro.
15752 (try_scrolling): Use it when setting scroll_limit.
15753 Limit scrolling to 100 screen lines.
15754 (redisplay_window): Even when falling back on "recentering",
15755 position point in the window according to scroll-conservatively,
15756 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
15758 (try_scrolling): When point is above the window, allow searching
15759 as far as scroll_max, or one screenful, to compute vertical
15760 distance from PT to the scroll margin position. This prevents
15761 try_scrolling from unnecessarily failing when
15762 scroll-conservatively is set to a value slightly larger than the
15763 window height. Clean up the case of PT below the margin at bottom
15764 of window: scroll_max can no longer be INT_MAX. When aggressive
15765 scrolling is in use, don't let point enter the opposite scroll
15766 margin as result of the scroll.
15767 (syms_of_xdisp) <scroll-conservatively>: Document the
15768 threshold of 100 lines for never-recentering scrolling.

15778 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
15780 * indent.c (Fvertical_motion):
15781 * window.c (window_scroll_pixel_based, Frecenter):
15782 Don't pass `need_y_p' to `move_it_by_lines'.
15784 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
15786 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
15787 steal a few bits to be more compact.
15788 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
15789 Remove unneeded casts.
15791 * bytecode.c (Fbyte_code): CAR and CDR can GC.
15793 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
15795 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
15796 binding" message (bug#7967).
15798 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
15800 Fix more problems found by GCC 4.6.0's static checks.
15802 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
15803 Remove unused local var.
15805 * editfns.c (Fmessage_box): Remove unused local var.
15807 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
15808 (note_mode_line_or_margin_highlight, note_mouse_highlight):
15809 Omit unused local vars.
15810 * window.c (shrink_windows): Omit unused local var.
15811 * menu.c (digest_single_submenu): Omit unused local var.
15812 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
15813 Omit unused local var.
15815 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
15816 Don't assume string length fits in int.
15817 (keyremap_step, read_key_sequence): Use size_t for sizes.
15818 (read_key_sequence): Don't check last_real_key_start redundantly.
15820 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
15821 instead of alloca (Bug#8344).
15823 * eval.c (Fbacktrace): Don't assume nargs fits in int.
15824 (Fbacktrace_frame): Don't assume nframes fits in int.
15826 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

15833 * cm.c (calccost): Turn while-do into do-while, for clarity.
15835 * keyboard.c (syms_of_keyboard): Use the same style as later
15836 in this function when indexing through an array. This also
15837 works around GCC bug 48267.
15839 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
15841 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
15843 * chartab.c (sub_char_table_ref_and_range): Redo for slight
15844 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
15846 * keyboard.c, keyboard.h (num_input_events): Now size_t.
15847 This avoids undefined behavior on integer overflow, and is a bit
15848 more convenient anyway since it is compared to a size_t variable.
15850 Variadic C functions now count arguments with size_t, not int.
15851 This avoids an unnecessary limitation on 64-bit machines, which
15852 caused (substring ...) to crash on large vectors (Bug#8344).

15862 * fns.c (concat): Likewise.
15863 * frame.c (x_set_frame_parameters): Likewise.
15864 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
15865 0 if not found, not -1. All callers changed.
15867 * alloc.c (garbage_collect): Don't assume stack size fits in int.
15868 (stack_copy_size): Now size_t, not int.
15869 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
15871 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
15873 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

15890 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
15891 don't set the hook to nil, but remove the offending function instead.

15894 Vcommand_hook_internal.

16078 unconditionally since it does the check itself.
16080 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16082 Fix more problems found by GCC 4.5.2's static checks.
16084 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16085 the first time through the loop, since we know p0 < p1 then.
16086 This also avoids a gcc -Wstrict-overflow warning.
16088 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16089 leading to a memory leak, possible in functions like
16090 load_charset_map_from_file that can allocate an unbounded number
16091 of objects (Bug#8318).
16093 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16094 that could (at least in theory) be that large.
16096 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16097 This is less likely to overflow, and avoids undefined behavior if
16098 overflow does occur. All callers changed. Use strtoul to scan
16099 for the unsigned long integer.
16100 (pint2hrstr): Simplify and tune code slightly.
16101 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16103 * scroll.c (do_scrolling): Work around GCC bug 48228.
16104 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16106 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16107 This also avoids a warning with gcc -Wstrict-overflow.
16108 (validate_x_resource_name): Simplify count usage.
16109 This also avoids a warning with gcc -Wstrict-overflow.
16111 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16114 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16116 * process.c (Fmake_network_process): Use socklen_t, not int,
16117 where POSIX says socklen_t is required in portable programs.
16118 This fixes a porting bug on hosts like 64-bit HP-UX, where
16119 socklen_t is wider than int (Bug#8277).
16120 (Fmake_network_process, server_accept_connection):
16121 (wait_reading_process_output, read_process_output):
16124 * process.c: Rename or move locals to avoid shadowing.

16134 Make tparam.h and terminfo.c consistent.
16135 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16136 Include tparam.h instead, since it declares them.
16137 * cm.h (PC): Remove extern decl; tparam.h now does this.
16138 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16139 * terminfo.c: Include tparam.h, to check interfaces.
16140 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16141 (tparam): Adjust signature to match interface in tparam.h;
16142 this removes some undefined behavior. Check that outstring and len
16143 are zero, which they always are with Emacs.
16144 * tparam.h (PC, BC, UP): New extern decls.
16146 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16147 (xftfont_open): Rename locals to avoid shadowing.
16149 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

16159 * xml.c (make_dom): Now static.
16161 * composite.c (composition_compute_stop_pos): Rename local to
16163 (composition_reseat_it): Remove unused locals.
16164 (find_automatic_composition, composition_adjust_point): Likewise.
16165 (composition_update_it): Mark var as initialized.
16166 (find_automatic_composition): Mark vars as initialized,
16167 with a FIXME (Bug#8290).

16171 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16172 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16173 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16174 to avoid shadowing.
16176 * textprop.c (property_change_between_p): Remove; unused.
16178 * intervals.c (interval_start_pos): Now static.
16180 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16183 Rename locals to avoid shadowing.
16185 * sound.c (wav_play, au_play, Fplay_sound_internal):
16186 Fix pointer signedness.
16187 (alsa_choose_format): Remove unused local var.
16188 (wav_play): Initialize a variable to 0, to prevent undefined
16189 behavior (Bug#8278).
16191 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16193 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16195 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16196 clobbering (Bug#8298).
16197 * sysdep.c (sys_subshell): Likewise.
16198 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16200 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16201 This should get cleaned up, so that child_setup has the
16202 same signature on all platforms.
16204 * callproc.c (call_process_cleanup): Now static.
16205 (relocate_fd): Rename locals to avoid shadowing.
16207 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16209 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16210 not to be necessary, and produces flickering.
16212 2011-03-20 Glenn Morris <rgm@gnu.org>
16214 * config.in: Remove file.
16216 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16218 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16219 are now in src/globals.h.
16220 (syms_of_minibuf): Remove spurious & from previous change.
16222 2011-03-20 Leo Liu <sdl.web@gmail.com>
16224 * minibuf.c (completing-read-function): New variable.
16225 (completing-read-default): Rename from completing-read.
16226 (completing-read): Call completing-read-function.
16228 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16230 * xfaces.c (Fx_load_color_file):
16231 Read color file from absolute filename (bug#8250).
16233 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16235 * makefile.w32-in: Update dependencies.
16237 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16239 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16246 (sigchld_handler): Now static.
16248 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16249 That way, the code declares only the vars that it needs.
16250 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16251 * s/cygwin.h (PTY_ITERATION): Likewise.
16252 * s/darwin.h (PTY_ITERATION): Likewise.

16259 (CONSTANTLIM): Remove; unused.
16260 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16261 Define only if needed.
16263 * unexelf.c (unexec): Name an expression,
16264 to avoid gcc -Wbad-function-cast warning.
16265 Use a different way to cause a compilation error if anyone uses
16266 n rather than nn, a way that does not involve shadowing.
16267 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16269 * deps.mk (unexalpha.o): Remove; unused.
16271 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16272 * unexec.h: New file.
16273 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16274 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16275 Depend on unexec.h.
16276 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16277 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16278 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16279 Change as necessary to match prototype in unexec.h.
16281 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

16297 instead of using an uninitialized var.
16298 (font_sort_entities): Mark var as initialized.
16300 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16302 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16326 * callint.c (quotify_arg, quotify_args): Now static.
16327 (Fcall_interactively): Rename locals to avoid shadowing.
16328 Use const pointer when appropriate.

16334 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16335 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16336 some of which prompt warnings from gcc -Wbad-function-cast.
16337 (Fformat_time_string, Fencode_time, Finsert_char):
16338 (Ftranslate_region_internal, Fformat):
16339 Rename or remove local vars to avoid shadowing.
16340 (Ftranslate_region_internal): Mark var as initialized.
16342 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16345 * lisp.h (eassert): Check that the argument compiles, even if
16346 ENABLE_CHECKING is not defined.
16348 * data.c (Findirect_variable): Name an expression, to avoid
16349 gcc -Wbad-function-cast warning.
16350 (default_value, arithcompare, arith_driver, arith_error): Now static.

16358 Rename locals to avoid shadowing.
16359 (mark_stack): Move local variables into the #ifdef region where
16361 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16362 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16364 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16365 (GC_STRING_CHARS): Remove; not used.
16366 (Fmemory_limit): Cast sbrk's returned value to char *.
16368 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16369 avoids undefined behavior in theory.
16371 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16373 Use functions, not macros, for up- and down-casing (Bug#8254).
16374 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16375 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16376 to use the following functions instead of these macros.
16377 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16378 EMACS_INT, since callers assume the returned value fits in int.
16379 (upcase1): Likewise, for UPCASE_TABLE.
16380 (uppercasep, lowercasep, upcase): New static inline functions.
16381 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16382 the race-condition problem in the old DOWNCASE.
16384 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

16388 Remove unused local vars.
16389 (FREE_VAR): Rewrite so as not to use empty "else",
16390 which gcc can warn about.
16391 (regex_compile, re_match_2_internal): Mark locals as initialized.
16392 (RETALLOC_IF): Define only if needed.
16393 (WORDCHAR_P): Likewise. This one is never needed, but is used
16394 only in a comment talking about a compiler bug, so put inside
16395 the #if 0 of that comment.
16396 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16397 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16400 * search.c (boyer_moore): Rename locals to avoid shadowing.
16401 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16402 (PREV_CHAR_BOUNDARY): Likewise.

16412 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16414 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16415 Rename locals to avoid shadowing.
16416 (Fvertical_motion): Mark locals as initialized.
16418 * casefiddle.c (casify_object, casify_region): Now static.
16419 (casify_region): Mark local as initialized.
16421 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16423 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16424 New macros, so that the caller can use some names other than
16425 gcpro1, gcpro2, etc.
16426 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16428 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16429 argument, for consistency with GCPRO2_VAR, etc: it is now the
16430 prefix of the variable, not the variable itself. All uses
16432 * dired.c (directory_files_internal, file_name_completion):
16433 Rename locals to avoid shadowing.
16435 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16436 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16437 dired.c's scmp function, had undefined behavior.
16438 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16439 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16440 * buffer.h: ... to here, because these macros use current_buffer,
16441 and the new implementation with inline functions needs to have
16442 current_buffer in scope now, rather than later when the macros
16444 (downcase, upcase1): New static inline functions.
16445 (DOWNCASE, UPCASE1): Reimplement using these functions.
16446 This avoids undefined behavior in expressions like
16447 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16448 from race conditions in accessing the global variables
16449 case_temp1 and case_temp2.
16450 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16451 * lisp.h (case_temp1, case_temp2): Remove their decls.
16452 * character.h (ASCII_CHAR_P): Move from here ...
16453 * lisp.h: ... to here, so that the inline functions mentioned
16454 above can use them.
16456 * dired.c (directory_files_internal_unwind): Now static.
16458 * fileio.c (file_name_as_directory, directory_file_name):
16459 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16461 (file_name_as_directory): Use const pointers when appropriate.
16462 (Fexpand_file_name): Likewise. In particular, newdir might
16463 point at constant storage, so make it a const pointer.
16464 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16465 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16467 (Fset_file_times, Finsert_file_contents, auto_save_error):
16468 Rename locals to avoid shadowing.
16470 * minibuf.c (choose_minibuf_frame_1): Now static.
16471 (Ftry_completion, Fall_completions): Rename or remove locals
16472 to avoid shadowing.
16474 * marker.c (bytepos_to_charpos): Remove; unused.
16476 * lisp.h (verify_bytepos, count_markers): New decls,
16477 so that gcc does not warn that these functions aren't declared.
16479 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16480 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16481 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16482 (copy_text): Remove unused local var.
16484 * filelock.c (within_one_second): Now static.
16485 (lock_file_1): Rename local to avoid shadowing.
16487 * buffer.c (fix_overlays_before): Mark locals as initialized.
16488 (fix_start_end_in_overlays): Likewise. This function should be
16489 simplified by using pointers-to-pointers, but that's a different
16491 (switch_to_buffer_1): Now static.
16492 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16493 (report_overlay_modification): Rename locals to avoid shadowing.
16495 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
16496 Fix pointer signedness issue.
16497 (sys_subshell): Mark local as volatile if checking for lint,
16498 to suppress a gcc -Wclobbered warning that does not seem to be right.
16499 (MAXPATHLEN): Define only if needed.
16501 * process.c (serial_open, serial_configure): Move decls from here ...
16502 * systty.h: ... to here, so that they can be checked.
16504 * fns.c (get_random, seed_random): Move extern decls from here ...
16505 * lisp.h: ... to here, so that they can be checked.
16507 * sysdep.c (reset_io): Now static.
16508 (wait_for_termination_signal): Remove; unused.
16510 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
16511 (copy_keymap_item, append_key, push_text_char_description):
16513 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
16514 (DENSE_TABLE_SIZE): Remove; unused.
16515 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
16516 (describe_map_tree):
16517 Rename locals to avoid shadowing.
16519 * keyboard.c: Declare functions static if they are not used elsewhere.
16520 (echo_char, echo_dash, cmd_error, top_level_2):
16521 (poll_for_input, handle_async_input): Now static.
16522 (read_char, kbd_buffer_get_event, make_lispy_position):
16523 (make_lispy_event, make_lispy_movement, apply_modifiers):
16524 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
16525 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
16526 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
