3 Simplify, document, and port floating-point (Bug#12381).
4 The porting part of this patch fixes bugs on non-IEEE platforms
5 with frexp, ldexp, logb.
6 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
8 * floatfns.c: Simplify discussion of functions that Emacs doesn't
9 support, by removing commented-out code and briefly listing the
10 C89 functions excluded. The commented-out stuff was confusing
11 maintenance, e.g., we thought we needed cbrt but it was commented out.
12 (logb): Remove decl; no longer needed.
13 (isfinite): New macro, if not already supplied.
14 (isnan): Don't replace any existing macro.
15 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
16 are present on all C89 platforms.
17 (Ffrexp): Do not special-case zero, as frexp does the right thing
19 (Flogb): Do not use logb, as it doesn't have the desired meaning
20 on hosts that use non-base-2 floating point. Instead, stick with
21 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
22 frexp, to avoid getting an unspecified result.
24 * xdisp.c (Qinhibit_debug_on_message): Now static.
26 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
28 * nsterm.m (ns_update_begin): Set clip path to whole view by using
29 NSBezierPath (Bug#12131).
31 2012-09-10 Chong Yidong <cyd@gnu.org>
33 * fns.c (Fdelq, Fdelete): Doc fix.
35 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
37 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
38 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
40 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
42 * lisp.h (make_lisp_ptr): New macro to replace XSET.
43 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
46 2012-09-09 Eli Zaretskii <eliz@gnu.org>
48 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
49 left fringe if the window has a left margin. This avoids leaving
50 traces of the cursor because its leftmost pixel is not drawn over.
52 * dispnew.c (update_window_line): When the left margin area of a
53 screen line is updated, set the redraw_fringe_bitmaps_p flag of
54 that screen line. (Bug#12277)
56 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
58 Assume C89 or later for math functions (Bug#12381).
59 This simplifies the code, and makes it a bit smaller and faster,
60 and (most important) makes it easier to clean up signal handling
61 since we can stop worring about floating-point exceptions in
62 library code. That was a problem before C89, but the problem
63 went away many years ago on all practical Emacs targets.
64 * data.c, image.c, lread.c, print.c:
65 Don't include <math.h>; no longer needed.
66 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
67 might be autoconfigured, as that never happens.
69 * doprnt.c (DBL_MAX_10_EXP):
71 Remove. C89 or later always defines these.
72 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
73 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
74 (arith_error, domain_error, domain_error2):
75 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
76 no longer needed -- we simply return what C returns. All uses removed.
77 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
79 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
80 Remove. All uses expanded, as these macros are no longer used
81 more than once and are now more trouble than they're worth.
82 (Ftan): Use tan, not sin / cos.
83 (Flogb): Assume C89 frexp.
84 (fmod_float): Assume C89 fmod.
85 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
86 (init_floatfns): Remove. All uses removed.
88 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
90 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
91 compositeToPoint for OSX < 10.6 (Bug#12390).
93 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
95 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
96 This produces more-accurate results.
98 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
100 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
103 2012-09-08 Chong Yidong <cyd@gnu.org>
105 * syntax.c (Fstring_to_syntax): Doc fix.
107 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
109 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
110 in the internal border.
111 (x_set_window_size): Remove static variables and their usage.
112 (ns_redraw_scroll_bars): Fix NSTRACE arg.
113 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
114 fringe/internal border adjustment (Bug#11052).
115 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
116 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
117 (ns_fix_rect_ibw): Remove.
118 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
119 (ns_dumpglyphs_box_or_relief): Ditto.
120 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
122 (ns_dumpglyphs_image): Ditto.
123 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
125 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
126 their usage. Add fringe_extended_p and its use as in other terms.
127 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
128 scroll bar was removed.
129 (updateFrameSize): New function.
130 (windowDidResize): Move code to updateFrameSize and call it.
132 * nsterm.h (EmacsView): Add updateFrameSize.
134 2012-09-07 Chong Yidong <cyd@gnu.org>
136 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
138 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
140 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
142 More signal-handler cleanup (Bug#12327).
143 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
144 Problem introduced when merging patches. Noted by Eli Zaretskii in
145 <http://bugs.gnu.org/12327#67>.
146 * floatfns.c: Comment fix.
147 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
148 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
149 and anyway the declaration is harmless even if SIGDANGER is not defined.
150 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
151 defined BROKEN_FIONREAD). systty.h formerly did this, but other
152 source files not surprisingly expected syssignal.h to define, or
153 not define, SIGIO, and it's cleaner to do it that way, for consistency.
154 Include <sys/ioctl.h>, for FIONREAD.
155 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
156 This eliminates a problem whereby other files mysteriously had
157 to include "syssignal.h" before including "systty.h" if they
158 wanted to use "#ifdef SIGIO".
160 2012-09-07 Eli Zaretskii <eliz@gnu.org>
162 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
164 * w32.c (sigemptyset): Empty the set.
165 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
167 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
169 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
171 * alloc.c (mark_buffer): Revert unsafe marking optimization.
172 (mark_object): Likewise for frame objects.
174 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
176 * syssignal.h (handle_on_main_thread): Always declare,
177 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
178 This ports to platforms without HAVE_PTHREAD.
180 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
182 Signal-handler cleanup (Bug#12327).
183 Emacs's signal handlers were written in the old 4.2BSD style with
184 sigblock and sigmask and so forth, and this led to some
185 inefficiencies and confusion. Rewrite these to use
186 pthread_sigmask etc. without copying signal sets around. Also,
187 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
188 'signal', and instead use functions that do not attempt to take
189 over the system name space. This patch causes Emacs's text
190 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
191 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
192 Do not include <signal.h> or "syssignal.h", as these
193 modules do not use signals.
194 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
195 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
196 Do not include <signal.h>, as "syssignal.h" does that for us now.
197 * atimer.c (sigmask_atimers): New function.
198 (block_atimers, unblock_atimers): New functions,
199 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
201 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
202 no longer needed here.
203 * emacs.c (main): Inspect existing signal handler with sigaction,
204 so that there's no need to block and unblock SIGHUP.
205 * sysdep.c (struct save_signal): New member 'action', replacing
206 old member 'handler'.
207 (save_signal_handlers, restore_signal_handlers):
208 Use sigaction instead of 'signal' to save and restore.
209 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
210 New function. All users of 'signal' modified to use set_sighandler
211 if they're writeonly, and to use sys_signal if they're read+write.
212 (emacs_sigaction_init, forwarded_signal): New functions.
213 (sys_signal): Remove. All uses replaced by calls to sigaction
214 and emacs_sigaction_init, or by direct calls to 'signal'.
215 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
216 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
217 all uses replaced by pthread_sigmask etc. calls.
218 * syssignal.h: Include <signal.h>.
219 (emacs_sigaction_init, forwarded_signal): New decls.
220 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
221 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
222 (sigmask, sys_sigmask): Remove; no longer needed.
223 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
224 (sigblock, sigunblock, sigfree):
225 (sigsetmask) [!defined sigsetmask]:
226 Remove. All uses replaced by pthread_sigmask.
227 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
228 no longer need to be replaced, and its typical old uses
229 are now done via emacs_sigaction_init and sigaction.
230 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
231 (sys_sigdel): Remove; unused.
232 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
234 2012-09-06 Eli Zaretskii <eliz@gnu.org>
236 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
237 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
239 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
241 Explicitly mark buffer_defaults and buffer_local_symbols.
242 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
243 mark_local_symbols here.
244 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
245 since special buffers aren't marked here any more.
246 (allocate_buffer): Chain new buffer with all_buffers here...
247 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
249 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
250 (syms_of_buffer): Remove staticpro of the above.
251 (init_buffer_once): Set names for buffer_defaults and
252 buffer_local_symbols.
254 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
256 Use bool for booleans in font-related modules.
257 * font.c (font_intern_prop, font_style_to_value)
258 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
259 (generate_otf_features, font_check_otf_features, font_check_otf)
260 (font_match_p, font_list_entities, font_at):
261 * fontset.c (fontset_id_valid_p, reorder_font_vector
262 (fontset_find_font, Fset_fontset_font)
263 (face_suitable_for_char_p) [0]:
264 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
265 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
266 (m17n_flt_initialized, ftfont_shape_by_flt):
267 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
268 * nsfont.m (nsfont_draw):
269 * w32font.c (w32font_draw):
270 * w32term.c (x_draw_glyphless_glyph_string_foreground):
271 Use bool for booleans.
272 * font.h: Adjust to above API changes.
273 (struct font, struct font_driver, struct font_driver_list):
274 Use bool for booleans.
275 (struct font): Remove useless member encoding_type.
277 * fontset.c, xftfont.c: Omit unnecessary static decls.
279 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
281 * alloc.c (mark_object): Revert window marking code
282 since it's unsafe for the Fset_window_configuration.
284 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
286 Fix race conditions with signal handlers and errno (Bug#12327).
287 Be more systematic about preserving errno whenever a signal
288 handler returns, even if it's not in the main thread. Do this by
289 renaming signal handlers to distinguish between signal delivery
290 and signal handling. All uses changed.
291 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
292 * data.c (deliver_arith_signal): Rename from arith_error.
293 * dispnew.c (deliver_window_change_signal): Rename from
294 window_change_signal.
295 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
296 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
297 * keyboard.c (deliver_input_available_signal): Rename from
298 input_available_signal.
299 (deliver_user_signal): Rename from handle_user_signal.
300 (deliver_interrupt_signal): Rename from interrupt_signal.
301 * process.c (deliver_pipe_signal): Rename from send_process_trap.
302 (deliver_child_signal): Rename from sigchld_handler.
303 * atimer.c (handle_alarm_signal):
304 * data.c (handle_arith_signal):
305 * dispnew.c (handle_window_change_signal):
306 * emacs.c (handle_fatal_signal, handle_danger_signal):
307 * keyboard.c (handle_input_available_signal):
308 * keyboard.c (handle_user_signal, handle_interrupt_signal):
309 * process.c (handle_pipe_signal, handle_child_signal):
310 New functions, with the actual signal-handling code taken from the
311 original respective signal handlers, sans the sporadic attempts to
312 preserve errno, since that's now done by handle_on_main_thread.
313 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
314 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
315 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
317 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
318 Move initialization of main_thread to sysdep.c's init_signals.
319 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
320 our usage, and simplifies the mainline code.
321 (record_child_status_change): New static function, as a helper
322 for handle_child_signal, and with most of the old child handler's
324 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
325 (handle_child_signal): Use the above.
326 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
327 Moved here from emacs.c.
328 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
329 code moved here from emacs.c's main function.
330 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
331 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
332 lets callers save and restore errno properly.
334 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
336 Remove redundant or unused things here and there.
337 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
338 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
339 * editfns.c (Fcompare_buffer_substrings): Likewise.
340 * frame.h (struct terminal, struct font_driver_list):
341 Remove redundant declarations.
342 * window.h (Qleft, Qright): Likewise.
344 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
346 Do not mark objects from deleted buffers, windows and frames.
347 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
348 (mark_object): Likewise for windows and frames.
350 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
352 * alloc.c (valid_lisp_object_p): Treat killed buffers,
353 buffer_defaults and buffer_local_symbols as valid objects.
354 Return special value to denote them.
356 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
358 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
359 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
360 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
361 (file_name_absolute_p, Fsubstitute_in_file_name):
362 (check_executable, check_writable, Ffile_accessible_directory_p)
363 (Fset_file_selinux_context, Fdefault_file_modes)
364 (Finsert_file_contents, choose_write_coding_system)
365 (Fwrite_region, build_annotations, a_write, e_write)
367 * filelock.c (boot_time_initialized, get_boot_time)
368 (get_boot_time_1, lock_file_1, within_one_second):
369 * floatfns.c (in_float):
370 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
371 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
372 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
373 * lisp.h (struct Lisp_Hash_Table.cmpfn):
374 * window.c (compare_window_configurations):
375 Use bool for booleans.
376 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
377 (Fdefault_file_modes): Now mode_t, not int, for modes.
378 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
379 (internal_delete_file): Now returns void, not a (boolean) int,
380 since nobody was looking at the return value.
381 * lisp.h, window.h: Adjust to above API changes.
383 * xdisp.c (set_message): Simplify and reindent last change.
385 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
387 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
389 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
391 * eval.c (call_debugger): Make the function non-static so that we
392 can call it from set_message.
394 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
395 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
397 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
399 Give more-useful info on a fatal error (Bug#12328).
400 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
401 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
402 of doing the work ourselves.
403 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
405 (fatal_error_backtrace): New function, taken from the guts
406 of the old fatal_error_signal, but with a new option to output
408 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
409 info about the signal than just its number.
410 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
411 * sysdep.c: Include <execinfo.h>
412 (emacs_backtrace): New function, taken partly from the previous
413 code of the 'die' function.
414 (emacs_abort): Call fatal_error_backtrace rather than abort.
416 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
418 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
419 eager (load-time) macro-expansion.
420 * lisp.mk (lisp): Add macroexp.
422 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
424 Simplify redefinition of 'abort' (Bug#12316).
425 Do not try to redefine the 'abort' function. Instead, redo
426 the code so that it calls 'emacs_abort' rather than 'abort'.
427 This removes the need for the NO_ABORT configure-time macro
428 and makes it easier to change the abort code to do a backtrace.
429 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
430 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
431 Remove; sysdep.c's emacs_abort now takes its place.
432 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
433 'abort' changed to use 'emacs_abort'.
434 * msdos.c (dos_abort) [defined abort]: Remove; not used.
435 (abort) [!defined abort]: Rename to ...
436 (emacs_abort): ... new name.
437 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
438 the place of the old 'abort' in emacs.c.
439 * w32.c, w32fns.c (abort): Do not #undef.
440 * w32.c (emacs_abort): Rename from w32_abort.
442 2012-09-04 Eli Zaretskii <eliz@gnu.org>
444 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
445 offsets[j].dv, since the y axis of the screen coordinates points
446 down, while the y axis of the font definition coordinates points
447 up. This fixes display of Arabic diacritics such as KASRA and
448 KASRATAN. (Bug#11860)
450 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>

456 (png_load, my_error_exit, jpeg_load):
457 * process.c (send_process_trap, send_process):
458 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
459 The underscored versions are up to 30x faster on some hosts.
460 Formerly, the code used setjmp+longjmp sometimes and
461 _setjmp+_longjmp at other times, with no particular reason to
462 prefer setjmp+longjmp.

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

536 * xterm.c (updating_frame): Remove decl of nonexistent object.
538 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)

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

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

920 * alloc.c (enum mem_type): New memory type.
921 (refill_memory_reserve): Use new type for spare memory.
922 This prevents live_cons_p and live_string_p from incorrect
923 detection of uninitialized objects from spare memory as live.
925 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
928 * Makefile.in (.PHONY): versioclean -> versionclean.
930 Remove unused external symbols.
931 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
932 * window.c (Qwindow_valid_p, decode_valid_window):
933 Now static, not extern.
934 * data.c (Qinterval): Remove; unused.
935 (syms_of_data): Do not define 'interval'.
936 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
937 * window.h (decode_valid_window):
940 * character.c, charset.c, chartab.c: Use bool for booleans.
941 * character.c (lisp_string_width, string_count_byte8)
942 (string_escape_byte8):
943 * charset.c (charset_map_loaded, load_charset_map, read_hex):
944 (load_charset_map_from_file, map_charset_chars)
945 (Fdefine_charset_internal, define_charset_internal)
946 (Fdeclare_equiv_charset, find_charsets_in_text)
947 (Ffind_charset_region, char_charset, Fiso_charset):
948 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
949 (sub_char_table_set, sub_char_table_set_range)
950 (char_table_set_range, optimize_sub_char_table)
951 (map_sub_char_table):
952 Use bool for boolean.
953 * character.c (str_to_unibyte): Omit last boolean argument; it was
954 always 0. All callers changed.
955 * character.h, charset.h: Adjust to match previous changes.
956 * character.h (char_printable_p): Remove decl of nonexistent function.
957 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
958 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
959 are all boolean, so make them single-bit bitfields.
961 * lisp.h (ASET): Remove attempt to detect side effects.
962 It was meant to be temporary and it often doesn't work,
963 because when IDX has side effects the behavior of IDX==IDX
964 is undefined. See Stefan Monnier in
965 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
967 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
969 * lisp.h (functionp): New function (extracted from Ffunctionp).
971 * eval.c (Ffunctionp): Use it.
973 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
975 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
976 as that's faster and simpler than static storage. Don't bother
977 with the g_main_context_query overhead if g_main_context_pending
978 says no events are pending.
979 (gfds, gfds_size): Remove these static vars.
980 (xgselect_initialize): Remove; no longer needed.
981 All uses and decls removed.
983 * emacs.c (fatal_error_signal_hook): Remove.
984 All uses removed. This leftover from old code was always 0.
986 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
987 * casefiddle.c (casify_object, casify_region):
988 * casetab.c (set_case_table):
989 * category.c, category.h (word_boundary_p):
990 * category.h (CHAR_HAS_CATEGORY):
991 Use bool for booleans, instead of int.
993 2012-08-25 Eli Zaretskii <eliz@gnu.org>
995 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
997 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
999 On assertion failure, print backtrace if available.
1000 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1001 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1002 * Makefile.in (LIB_EXECINFO): New macro.
1005 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1006 * bytecode.c (exec_byte_code):
1007 * callint.c (check_mark, Fcall_interactively):
1008 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1009 (getenv_internal, sync_process_alive, call_process_exited):
1010 * lisp.h (USE_SAFE_ALLOCA):
1011 Use bool for booleans, instead of int.
1012 * lisp.h, process.h: Adjust prototypes to match above changes.
1013 * callint.c (Fcall_interactively): Don't assume the mark's
1014 offset fits in 'int'.
1016 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1018 * buffer.c, buffer.h: Use bool for boolean.
1019 * buffer.c (reset_buffer_local_variables)
1020 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1021 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1022 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1023 (overlay_touches_p, overlay_strings, Foverlay_put)
1024 (report_overlay_modification, call_overlay_mod_hooks):
1025 (mmap_enlarge, mmap_set_vars):
1026 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1027 Use bool for booleans, instead of int.
1028 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1029 since the 1-or-0 return value is always ignored anyway.
1030 (mmap_initialized_p):
1031 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1032 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1034 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1036 * bidi.c: Use bool for boolean.
1037 This is a bit more readable, and makes the text segment of bidi.o
1038 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1039 Presumably it's faster too.
1040 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1042 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1043 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1044 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1045 (bidi_explicit_dir_char, bidi_level_of_next_char)
1046 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1047 Use bool for booleans, instead of int.
1048 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1049 (bidi_unshelve_cache): Adjust decls to match code.
1051 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1053 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1056 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1058 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1059 * atimer.h: Include <stdbool.h>.
1061 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1063 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1064 compile time tests instead of run time tests on systems that do
1066 (FRAME_MAC_P): Remove leftover from deleted code.
1067 * frame.c (syms_of_frame): Remove leftover from deleted code.
1069 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1071 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1073 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1075 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1076 Otherwise, the compiler complains about (A?B:C) where B is void
1077 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1078 (fontset_add): Return void, for FONTSET_ADD.
1080 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1082 * alloc.c: Use bool for booleans.
1083 (gc_in_progress, abort_on_gc)
1084 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1085 (dont_register_blocks) [GC_MALLOC_CHECK]:
1086 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1087 (check_string_bytes, make_specified_string, memory_full)
1088 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1089 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1090 (mark_stack, valid_pointer_p, make_pure_string)
1091 (Fgarbage_collect, survives_gc_p, gc_sweep):
1092 Use bool for booleans, instead of int.
1093 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1094 Remove unused local.
1095 * alloc.c (PURE_POINTER_P):
1096 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1097 * editfns.c (Fformat):
1098 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1100 * fns.c (sweep_weak_table):
1101 * lisp.h (suppress_checking, push_message, survives_gc_p)
1102 (make_pure_string, gc_in_progress, abort_on_gc):
1103 * lread.c (readchar, read1):
1104 * print.c (Fprin1_to_string):
1105 * xdisp.c (push_message):
1106 Use bool for booleans affected directly or indirectly by
1109 Make recently-introduced setters macros.
1110 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1111 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1112 (set_fontset_default, set_fontset_fallback): Rename from their
1113 upper-case counterparts, and make them functions rather than macros.
1114 This is more consistent with the other recently-introduced setters.
1115 These don't need to be inline, since they're local.
1117 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1119 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1120 the loop (Bug#12247).
1122 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1124 * lisp.h (vcopy): Use memcpy rather than our own loop.
1125 This fixes a performance regression introduced by the recent
1126 addition of vcopy. This means 'vcopy' will need to be modified
1127 for a copying collector, but that's OK. Also, tighten the
1128 checking in the assertion.
1130 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1132 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1133 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1134 non-base glyph for the width of the base character, according to
1135 what x_draw_composite_glyph_string_foreground expects.
1136 Generate WADJUST value according to composition_gstring_width's
1137 expectations, to produce correct width of the composed character.
1138 Reverse the sign of the DU offset produced by ScriptPlace.
1140 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1142 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1144 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1146 Avoid direct writes to contents member of struct Lisp_Vector.
1147 * lisp.h (vcopy): New function to copy data into vector.
1148 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1149 * fns.c (Ffillarray): Use ASET.
1150 * keyboard.c (timer_check_2): Use AREF and ASET.
1151 (append_tool_bar_item, Frecent_keys): Use vcopy.
1152 * lread.c (read_vector): Use ASET.
1153 * msdos.c (Frecent_doskeys): Use vcopy.
1154 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1155 (Finternal_merge_in_global_face): Use ASET and vcopy.
1156 * xfont.c (xfont_list_pattern): Likewise.
1158 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1160 * window.c (Fwindow_point): For the selected window always return
1161 the position of its buffer's point.
1162 (Fset_window_point): For the selected window always go in its
1163 buffer to the specified position.
1165 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1167 Setter macros for fontsets.
1168 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1169 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1170 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1173 2012-08-20 Glenn Morris <rgm@gnu.org>
1175 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1176 Don't assume that `ln -f' works.
1178 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1180 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1181 and later about non-assignments with no effect. See discussion at
1182 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1185 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1187 Inline setter functions for Lisp_Objects slots of struct specbinding.
1188 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1191 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1193 * window.c (select_window): Always make selected window's buffer
1196 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1198 Use AREF and ASET for docstrings of category tables.
1199 * category.h (CATEGORY_DOCSTRING): Use AREF.
1200 (SET_CATEGORY_DOCSTRING): Use ASET.
1201 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1203 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1205 Inline setter functions for hash table members.
1206 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1207 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1208 (set_hash_key_and_value, set_hash_index, set_hash_next)
1209 (set_hash_hash): New functions.
1210 * charset.c, fns.c: Adjust users.
1212 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1214 Inline getter and setter functions for per-buffer values.
1215 * buffer.h (per_buffer_default, set_per_buffer_default)
1216 (per_buffer_value, set_per_buffer_value): New functions.
1217 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1218 * buffer.c, data.c: Adjust users.
1220 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1222 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1224 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1226 Rely on <config.h> + <unistd.h> to declare 'environ',
1227 as gnulib does this if the system doesn't.
1228 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1229 Remove declaration. MS-Windows declares it on stdlib.h which is
1230 included by conf_post.h.
1231 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1232 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1233 * vm-limit.c: Include <unistd.h>, for 'environ'.
1235 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1236 (start_of_data): Remove decl; mem-limits.h provides it.
1238 * xdisp.c (handle_invisible_prop): Make it a bit faster
1239 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1241 2012-08-19 Chong Yidong <cyd@gnu.org>
1243 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1246 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1248 * .gdbinit: Use call instead of set when calling a function in the
1251 * data.c (set_internal): Don't use set_blv_found.
1252 (Fkill_local_variable): Likewise.
1254 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1256 * nsfont.m (ns_ascii_average_width): Ensure the string
1257 ascii_printable is initialized with a null-terminated character
1258 array. Otherwise, it can contain undesired extra characters.
1260 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1262 port new setting code to Sun C 5.8 2005/10/13
1263 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1264 Return void, not Lisp_Object. Otherwise, the compiler
1265 complains about (A?B:C) where B is void and C is Lisp_Object
1266 when compiling CHAR_TABLE_SET, due to the recent change to
1267 the API of sub_char_table_set_contents.
1269 2012-08-18 Chong Yidong <cyd@gnu.org>
1271 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1272 for the string case (Bug#3874).
1274 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1276 * buffer.h (BSET): Remove (Bug#12215).
1277 Replace all uses with calls to new setter functions.

1307 New setter functions.
1309 * process.h (PSET): Remove (Bug#12215).

1322 (pset_type, pset_write_queue): New setter functions.
1324 * window.h (WSET): Remove (Bug#12215).
1325 Replace all uses with calls to new setter functions.
1326 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1327 (WINDOW_INLINE): New macro.

1346 New setter functions.
1348 * termhooks.h (TSET): Remove (Bug#12215).
1349 Replace all uses with calls to new setter functions.
1350 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1351 (TERMHOOKS_INLINE): New macro.
1352 (tset_charset_list, tset_selection_alist): New setter functions.
1353 * terminal.c (TERMHOOKS_INLINE):

2104 value of EMACSLOADPATH, as it is no longer needed.
2105 (check_windows_init_file): Now external, not static.

2111 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

2156 * alloc.c (record_xmalloc): New function.
2157 * lisp.h (record_xmalloc): New decl.
2158 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2159 more like a function. This is because the pointer cast is not
2160 needed. All uses changed.
2161 * print.c (print_string, print_error_message): Avoid length recalc.
2163 Improve fix for macroexp crash with debugging (Bug#12118).
2164 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

2168 (gc_aset): New function, which is like ASET but can be
2169 used in the garbage collector.

2198 with addition of handling of symlinks and support for 'lstat'.
2199 If possible, get file's attributes and security information by
2200 handle, not by name. Produce S_IFLNK bit for symlinks, when
2201 called from 'lstat'.
2202 (stat, lstat): New functions, call 'stat_worker'.
2203 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2204 symlinks when the underlying filesystem supports them.
2206 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
2208 Fix macroexp crash on Windows with debugging (Bug#12118).
2209 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2210 checking subscripts; problem introduced with the recent
2211 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2212 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2213 since it's used in non-static inline functions now.
2215 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2216 Don't assume buffer size fits in 'int'. Remove unused local.

2704 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
2706 Improve GDB symbol export (Bug#12036).
2707 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
2708 arms of an 'if', not using conditional expressions; otherwise GDB
2709 complains about the types in the unevaluated arm when the argument
2710 is an integer literal.
2711 (xgetint): Simplify expression.
2712 * alloc.c (gdb_make_enums_visible): New constant. This ports to
2713 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
2714 Zaretskii in <http://bugs.gnu.org/12036#13>.
2715 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
2716 needed now that we have gdb_make_enums_visible.
2717 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
2718 (enum enum_USE_LSB_TAG):
2719 New enum types, packaging up enums that need to be exported to GDB.
2721 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2723 Utility function to make a list from specified amount of objects.

2738 * xfns.c (syms_of_xfns): Likewise.
2740 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2742 Fast save_excursion_save and save_excursion_restore.
2743 * lisp.h (struct Lisp_Excursion): New data type.
2744 (PVEC_EXCURSION): New pseudovector type.
2745 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
2746 to deal with it. Adjust comments.
2747 (init_marker, attach_marker): New prototype.
2748 (unchain_marker): Adjust prototype.
2749 * marker.c (attach_marker): Change to global.

2757 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
2759 Fix export of symbols to GDB (Bug#12036).
2760 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
2761 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
2762 emacs.c, as this is a more-suitable home. Had this been done earlier
2763 the fix for 12036 would have avoided some of the problems noted in
2764 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
2765 would have been more obvious.
2766 * emacs.c: Do not include <verify.h>; no longer needed.
2767 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
2768 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
2769 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2770 Remove; now done in lisp.h.
2771 * lisp.h (PUBLISH_TO_GDB): New macro.
2772 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
2773 (DATA_SEG_BITS): Use it.
2774 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
2775 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
2776 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
2777 not be usable in #if. This simplifies things.
2779 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
2781 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
2783 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
2785 Simplify export of symbols to GDB (Bug#12036).
2786 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
2787 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
2788 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
2789 Adjust to changes in lisp.h and emacs.c, by using
2790 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
2791 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
2792 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
2793 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
2794 instead of gdb_valbits.
2795 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
2796 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
2797 instead of gdb_array_mark_flag.
2798 (xboolvector): Get size from $->size, not $->header.size.
2799 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
2800 (xreload, hook-run, hookpost-run): Remove.
2801 * emacs.c: Include <verify.h>.
2802 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
2803 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
2805 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
2806 (gdb_USE_LSB_TAG): New enum constants.
2807 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2808 Also define these as enum constants, so they're visible to GDB.
2809 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
2810 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
2811 as constants, so they're visible to GDB.
2812 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
2813 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
2814 Now enum constants, not macros, so they're visible to GDB.
2815 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
2816 more convenient now. All uses changed.
2817 (VALMASK) [USE_LSB_TAG]: Also define in this case.
2818 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
2820 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

2825 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
2827 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
2828 add argument, tune behavior, and adjust all callers.
2830 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
2832 Use typedef for EMACS_INT, EMACS_UINT.
2833 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
2834 than macros. This simplifies debugging in the usual case, since
2835 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
2836 and it allows expressions involving EMACS_INT casts.
2837 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
2839 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

2847 that FOCUS-FRAME can be omitted.
2849 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
2851 Adjust buffer text indirection counters at the end of Fkill_buffer.
2852 * buffer.c (Fkill_buffer): Adjust indirection counters when the
2853 buffer is definitely dead. This should really fix an issue reported
2854 by Christoph Scholtes again. (Bug#12007).
2855 (init_buffer_once): Initialize indirection counters of
2856 buffer_defaults and buffer_local_symbols (for sanity and safety).
2858 2012-07-24 Eli Zaretskii <eliz@gnu.org>
2860 * xdisp.c (init_iterator): Don't compute dimensions of truncation
2861 and continuation glyphs on tooltip frames, leave them at zero.
2862 Avoids continued lines in tooltips. (Bug#11832)
2864 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
2866 Simplify copy_overlay.
2867 * buffer.c (copy_overlay): Simplify. Use build_marker.

2876 it signals an error when a tooltip frame is being created.
2878 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
2880 Cleanup miscellaneous objects allocation and initialization.

2889 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
2891 Swap buffer text indirection counters in Fbuffer_swap_text.
2892 * buffer.c (Fbuffer_swap_text): Swap indirections too.
2893 This avoids crash reported by Christoph Scholtes at
2894 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
2896 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
2898 * nsmenu.m (Popdown_data): New struct.

2903 and autorelease them. Also autorelease img and matrix (Bug#12005).
2904 (dealloc): Remove (Bug#12005).

2921 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
2923 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
2924 as it's limited by the amount of memory, not by INT_MAX.
2926 2012-07-21 Eli Zaretskii <eliz@gnu.org>
2928 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
2929 in special-event-map. See the discussion at

2988 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
2989 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
2990 Adjust users accordingly.
2991 * font.h (font_open_by_name): Adjust prototype.

3009 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
3010 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
3011 'for_each_per_buffer_object_at'.
3012 All uses changed. It's better to use upper-case for macros that
3013 cannot be implemented as functions, to give the reader a clue
3014 that they're special.
3016 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
3018 * alloc.c (Fgarbage_collect): Tweak docstring.

3059 * intervals.c (merge_interval_right, merge_interval_left):
3060 Do not zero out this interval if it is absorbed by its children,
3061 as this interval's total length doesn't change in that case. See
3062 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
3064 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
3066 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
3067 when invoking (make-bool-vector N t) and N is a positive

3070 Remove some struct layout assumptions in bool vectors.
3071 * alloc.c (bool_header_size): New constant.
3072 (header_size, word_size): Move earlier, as they're now used earlier.

3075 padding before the data member of a bool vector.
3076 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3077 than doing the check by hand with an abort ().
3079 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3081 * eval.c (Fdefvar): Don't check constants since we only set the var if
3082 it's not yet defined anyway (bug#11904).
3084 * lisp.h (last_undo_boundary): Declare new var.
3085 * keyboard.c (command_loop_1): Set it.
3086 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3087 were auto-added by the command loop (bug#11774).
3089 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
3091 * w32font.c (Qsymbol): Remove local definition.

3580 2012-07-11 Glenn Morris <rgm@gnu.org>
3582 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
3583 since nothing has defined it on these platforms.
3585 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
3586 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.
3588 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
3589 * s/gnu-linux.h, s/hpux10-20.h, s/template.h, s/usg5-4-common.h:
3590 Move CLASH_DETECTION to configure.
3592 * s/gnu.h: Remove file, which is now empty.
3594 * s/gnu.h, s/gnu-linux.h:
3595 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
3597 2012-07-11 John Wiegley <johnw@newartisans.com>
3599 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
3600 function attribute, so we only use it if it exists in the
3603 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
3605 Avoid call to strlen in fast_c_string_match_ignore_case.
3606 * search.c (fast_c_string_match_ignore_case): Change to use
3607 length argument. Adjust users accordingly.
3608 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
3610 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

3627 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
3629 Avoid calls to strlen in font processing functions.
3630 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
3631 (font_open_by_name): Change to use length argument.
3632 Adjust users accordingly.
3633 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
3635 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
3636 Change to return ptrdiff_t.
3637 (xfont_list_pattern, xfont_match): Use length returned by
3638 xfont_decode_coding_xlfd.

3649 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
3651 Remove "#define unix" that is no longer needed (Bug#11905).
3652 * s/aix4-2.h (unix): Remove; no longer needed.
3654 EMACS_TIME simplification (Bug#11875).
3655 This replaces macros (which typically do not work in GDB)
3656 with functions, typedefs and enums, making the code easier to debug.
3657 The functional style also makes code easier to read and maintain.
3658 * systime.h: Include <sys/time.h> on all hosts, not just if
3659 WINDOWSNT, since 'struct timeval' is needed in general.
3660 (EMACS_TIME): Now a typedef, not a macro.
3661 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
3663 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

3665 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
3666 (EMACS_TIME_LE): Now functions, not macros.
3667 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
3668 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
3669 which are not functions. All uses rewritten to use:
3670 (make_emacs_time): New function.
3671 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
3672 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
3673 not functions. All uses rewritten to use the following, respectively:
3674 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
3675 (add_emacs_time, sub_emacs_time): New functions.
3676 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
3677 * fileio.c (Fcopy_file):
3678 * xterm.c (XTflash): Get the current time closer to when it's used.
3679 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

3685 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
3686 * frame.c (Fmake_terminal_frame):
3687 * gtkutil.c (get_utf8_string):
3689 * nsmenu.m (ns_update_menubar):
3690 * regex.c (regerror):
3691 Prefer memcpy to strncpy and strncat when either will do.
3692 * fileio.c (Fsubstitute_in_file_name):
3693 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
3694 (menu_separator_name_p):
3695 * nsmenu.m (ns_update_menubar):
3696 Prefer memcmp to strncmp when either will do.
3697 * nsterm.m: Include <ftoastr.h>.
3699 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
3700 Prefer snprintf to strncpy.
3701 * nsterm.m (ns_term_init):
3702 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
3703 * nsterm.m (ns_term_init):
3704 Avoid the need for strncpy, by using build_string or
3705 make_unibyte_string directly. Use dtoastr, not snprintf.
3706 * process.c (Fmake_network_process): Diagnose service names that
3707 are too long, rather than silently truncating them or creating
3708 non-null-terminated names.
3709 (Fnetwork_interface_info): Likewise, for interface names.
3710 * sysdep.c (system_process_attributes) [GNU_LINUX]:
3711 Prefer sprintf to strncat.
3712 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
3713 Prefer vsnprintf to vsprintf + strncpy.
3715 2012-07-10 Glenn Morris <rgm@gnu.org>
3717 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
3718 Clarify fallback case.
3720 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3722 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
3723 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
3724 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
3725 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
3726 where argument type is known to be a Lisp_Cons.
3728 2012-07-10 Tom Tromey <tromey@redhat.com>
3730 * bytecode.c (BYTE_CODE_THREADED): New macro.
3731 (BYTE_CODES): New macro. Replaces all old byte-code defines.
3732 (enum byte_code_op): New type.
3733 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

3736 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3738 Optimize pure C strings initialization.
3739 * lisp.h (make_pure_string): Fix prototype.
3740 (build_pure_c_string): New function, defined as static inline. This
3741 provides a better opportunity to optimize away calls to strlen when
3742 the function is called with compile-time constant argument.
3743 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
3744 argument, adjust users accordingly. Use build_pure_c_string where
3746 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
3747 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
3748 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
3750 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3752 Avoid calls to strlen in miscellaneous functions.
3753 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
3754 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
3755 * lread.c (openp): Likewise.
3757 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3759 Avoid calls to strlen in path processing functions.
3760 * fileio.c (file_name_as_directory): Add comment. Change to add
3761 srclen argument and return the length of result. Adjust users
3763 (directory_file_name): Fix comment. Change to add srclen argument,
3764 swap 1st and 2nd arguments to obey the common convention.
3765 Adjust users accordingly.
3766 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
3768 2012-07-10 Glenn Morris <rgm@gnu.org>
3770 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
3771 Move PENDING_OUTPUT_COUNT definition to configure.
3773 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
3774 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
3775 * s/gnu.h (DATA_START): Move definitions to configure.
3777 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
3778 We include usg5-4-common.h, which defines them both.
3780 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
3781 O_RDONLY already includes it).
3783 Stop ns builds setting the EMACSLOADPATH environment variable.
3784 * nsterm.m (ns_load_path): Rename from ns_init_paths.
3785 Now it does not set EMACSLOADPATH, just returns the load-path string.
3786 * nsterm.h: Update accordingly.
3787 * lread.c [HAVE_NS]: Include nsterm.h.
3788 (init_lread) [HAVE_NS]: Use ns_load_path.
3789 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
3791 2012-07-09 Glenn Morris <rgm@gnu.org>
3793 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
3794 since the included bsd-common.h does so.
3796 Stop ns builds setting the EMACSPATH environment variable.
3797 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
3798 (ns_init_paths): Do not set EMACSPATH.
3799 * nsterm.h (ns_exec_path): Add it.
3800 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
3803 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
3805 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
3807 * process.c (wait_reading_process_output): 'waitchannels' was unset
3808 when read_kbd || !NILP (wait_for_cell); fix this.
3810 Add GCC-style 'const' attribute to functions that can use it.
3811 * character.h (char_resolve_modifier_mask):
3812 * keyboard.h (make_ctrl_char):
3813 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
3814 (init_character_once, next_almost_prime, init_fns, init_image)
3815 (flush_pending_output, init_sound):
3816 * mem-limits.h (start_of_data):
3817 * menu.h (finish_menu_items):
3818 Add ATTRIBUTE_CONST.

3820 Declare the dummy function with ATTRIBUTE_CONST.
3821 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
3822 Add decls with ATTRIBUTE_CONST.
3824 Minor improvements to make_formatted_string.
3825 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
3826 where int is good enough, as vsprintf returns an int.
3827 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
3829 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3831 Use make_formatted_string to avoid double length calculation.
3832 * lisp.h (make_formatted_string): New prototype.
3833 * alloc.c (make_formatted_string): New function.
3834 * buffer.c (Fgenerate_new_buffer_name): Use it.
3835 * dbus.c (syms_of_dbusbind): Likewise.

3838 * frame.c (make_terminal_frame, set_term_frame_name)
3839 (x_report_frame_params): Likewise.
3840 * image.c (gs_load): Likewise.
3841 * minibuf.c (get_minibuffer): Likewise.

3856 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3858 Move marker debugging code under MARKER_DEBUG.
3859 * marker.c (MARKER_DEBUG): Move marker debugging code under
3860 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
3861 for bootstrap with --enable-checking (~3x slowdown reported
3862 by Juanma Barranquero <lekktu@gmail.com>).
3863 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
3865 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
3867 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
3868 See <http://bugs.gnu.org/11825#29>.
3870 2012-07-08 Eli Zaretskii <eliz@gnu.org>
3872 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
3873 has no font, use the frame's font. (Bug#11813)
3874 (display_line): Add commentary about displaying truncation glyphs
3876 (produce_special_glyphs): Move here from term.c.
3878 * term.c (produce_special_glyphs): Move to xdisp.c.
3880 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
3883 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
3885 * xdisp.c (display_line): Avoid warning about implicit declaration
3888 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
3890 * lisp.h: Remove empty conditional.
3892 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3894 * lread.c (load_path_check): Now static.
3896 Fix some minor --with-ns problems found by static checking.
3897 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
3898 (x_set_font) [!HAVE_X_WINDOWS]:
3899 * image.c (xpm_load_image) [HAVE_NS]:
3900 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
3901 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
3902 Remove unused local.
3903 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
3904 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
3905 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
3906 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
3907 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
3908 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
3909 Fix pointer signedness problem.
3910 * xfaces.c (FRAME_X_FONT_TABLE):
3911 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
3913 2012-07-07 Glenn Morris <rgm@gnu.org>
3915 * lread.c (load_path_check): New function, split from init_lread.
3916 (init_lread): Reorganize. Motivation:
3917 If EMACSLOADPATH is set, check/warn about that rather than the
3918 defaults, which we are not going to use. Hence we can remove
3919 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
3920 Don't warn if site-lisp directories are missing.
3921 If not installed, start from a blank load-path, since
3922 PATH_LOADSEARCH refers to the eventual installation directories.
3924 2012-07-07 Eli Zaretskii <eliz@gnu.org>
3926 Support truncation and continuation glyphs on GUI frames, when
3927 fringes are disabled. (Bug#11832)
3928 * xdisp.c (init_iterator): Get dimensions of truncation and
3929 continuation glyphs even if on GUI frames.
3930 Adjust it->last_visible_x on GUI frames when the left or right fringes,
3931 or both, are absent.
3932 (start_display, move_it_in_display_line_to): Handle the case of a
3933 GUI frame without a fringe to display continuation or truncation
3935 (insert_left_trunc_glyphs): Support GUI frames: make sure
3936 truncation glyphs overwrite enough glyphs from the current line to
3937 have sufficient space in pixels.
3938 (display_line): Support truncation and continuation glyphs on GUI
3939 frames. If some spare pixels are left on the line after inserting
3940 the truncation glyphs, fill that space with a stretch glyph of a
3941 suitably computed width.
3943 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
3944 produce_glyphs, to support GUI sessions.
3946 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3948 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
3950 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
3952 Do not require float-time's arg to fit in time_t (Bug#11825).
3953 This works better on hosts where time_t is unsigned, and where
3954 float-time is applied to the (negative) difference between two times.
3955 * editfns.c (decode_time_components): Last arg is now double *,
3956 not int *, and means to store all the result as a double, without
3957 worrying about whether the seconds part fits in time_t.
3958 All callers changed.
3959 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
3960 All callers changed.
3961 (Ffloat_time): Do not fail merely because the specified time falls
3962 outside of time_t range.
3964 2012-07-07 Glenn Morris <rgm@gnu.org>
3966 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

3970 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
3972 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
3973 Update dependencies.
3975 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
3977 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3979 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
3980 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
3981 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3982 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
3983 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
3984 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
3986 * xfont.c (compare_font_names): Redo to omit the need for casts.
3988 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
3990 * xfns.c (Fx_change_window_property): Doc fix.
3991 * w32fns.c (Fx_change_window_property): Doc fix.
3993 * w32fns.c (Fx_window_property): Accept the same arguments as the
3994 X Windows version. Doc fix.
3995 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3997 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3998 Eli Zaretskii <eliz@gnu.org>
4000 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4001 Windows-specific code from nt/config.nt moved here.
4002 Obsolete settings removed.
4004 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4006 * process.c: Avoid unnecessary calls to gettime.
4007 (wait_reading_process_output): Don't get the time of day
4008 when gobbling data immediately and not waiting, as there's no need
4009 for it in that case. This removes a FIXME.
4011 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4013 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4014 is defined (Bug#11768).
4016 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4018 Fix marker debugging code.
4019 * marker.c (byte_char_debug_check): Do not perform the check
4020 if buffer is not multibyte.
4021 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4022 Call byte_char_debug_check with correct arguments.
4024 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4026 Compile marker debugging code only if ENABLE_CHECKING is defined.
4027 * marker.c (byte_char_debug_check, count_markers):
4028 Use only if ENABLE_CHECKING is defined.
4029 (byte_debug_flag): Remove.
4030 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4031 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4033 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4035 Avoid code repetition in marker-related functions.
4036 * marker.c (attach_marker): New function.
4037 (Fset_marker, set_marker_restricted, set_marker_both)
4038 (set_marker_restricted_both): Use it.
4039 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4040 Consistently rename charno to charpos.
4041 (marker_position): Add eassert.
4042 (marker_byte_position): Convert to eassert.
4044 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4046 Simplify list operations in unchain_overlay and unchain_marker.
4047 * buffer.c (unchain_overlay): Simplify. Add comment.
4048 * marker.c (unchain_marker): Simplify. Fix comments.
4050 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4052 Introduce fast path for the widely used marker operation.
4053 * alloc.c (build_marker): New function.
4054 * lisp.h (build_marker): New prototype.
4055 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
4056 * composite.c (autocmp_chars): Likewise.
4057 * editfns.c (buildmark): Remove.
4058 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4059 (save_restriction_save): Use build_marker.
4060 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4061 * window.c (save_window_save): Likewise.
4063 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

4066 to avoid redundant calls to unchain_overlay.
4067 * buffer.c (drop_overlay): New function.
4068 (delete_all_overlays, Fdelete_overlay): Use it.
4069 * minibuf.c (get_minibuffer): Fix comment.
4071 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4073 Port to OpenBSD 5.1 amd64.
4074 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4075 This is needed for OpenBSD, and should be harmless on all BSD systems.
4076 Also, include <sys/sysctl.h>, as it should be available on all
4077 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4078 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4079 use p_pid member, not kp_proc.pid.
4081 2012-07-06 Glenn Morris <rgm@gnu.org>
4083 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4085 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4087 More xmalloc and related cleanup.
4088 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4095 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4096 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4098 Omit needless casts involving void * pointers and allocation.
4099 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4100 as the former is more robust if P's type is changed.
4101 Prefer xzalloc to xmalloc + memset 0.
4102 Simplify malloc-or-realloc to realloc.
4103 Don't worry about xmalloc returning a null pointer.
4104 Prefer xstrdup to xmalloc + strcpy.
4105 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4107 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4108 alloca of a constant.
4110 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4112 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4113 hscroll is larger than the line width. Fixes long and futile
4114 looping inside extend_face_to_end_of_line (on a TTY) producing
4115 glyphs that are not needed and thrown away.
4117 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4119 * marker.c (set_marker_restricted_both): Simplify by using
4122 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4124 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4126 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4128 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4129 not defined (Bug#11768).
4130 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4131 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4132 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4133 followed by gtk_box_set_homogeneous (Bug#11768).
4134 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4135 (update_theme_scrollbar_width, xg_create_scroll_bar):
4136 Use gtk_scrollbar_new (Bug#11768).
4137 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4138 (is_box_type): New function (Bug#11768).
4139 (xg_tool_item_stale_p): Call is_box_type.
4140 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4141 with default display (Bug#11768).

4145 * xdisp.c (window_hscroll_limited): New function.
4146 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4147 coordinates when window's hscroll is set to insanely large
4150 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4152 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4153 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4155 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4158 * lisp.h (xzalloc): New prototype. Omit needless casts.
4159 * alloc.c (xzalloc): New function. Omit needless casts.

4211 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4213 * fileio.c (time_error_value): Check the right error number.
4214 Problem reported by Troels Nielsen in
4215 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4217 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4219 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4220 This should be fixed in a better way; see Eli Zaretskii in
4221 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4222 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4224 * fileio.c (time_error_value): Rename from special_mtime.
4225 The old name's problems were noted by Eli Zaretskii in
4226 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4228 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4229 This variable's comment says Emacs needs at least one GDB-visible
4230 symbol of type enum pvec_type, to work around GDB problems.
4231 The symbol's value doesn't matter.
4233 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4234 that causes compilation to fail on pre-C99 compilers.
4236 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4238 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4239 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4241 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4243 * buffer.c (init_buffer_once): Fix initialization of
4244 headers for buffer_defaults and buffer_local_symbols.
4245 Reported by Juanma Barranquero <lekktu@gmail.com>.
4247 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4249 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4250 * lisp.h (enum pvec_type): Use fewer bits.
4251 (PSEUDOVECTOR_SIZE_BITS): New constant.
4252 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4253 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4254 change in pvec_type.
4255 (PSEUDOVECTOR_TYPEP): New macro.
4256 (TYPED_PSEUDOVECTORP): Use it.
4257 * fns.c (internal_equal): Adapt code to extract pvectype.
4258 * emacs.c (gdb_pvec_type): Update type.
4259 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
4260 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
4261 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4262 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4263 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4264 abusing vector->header.next.nbytes.
4265 (live_vector_p): Use PVEC_TYPE.
4266 (mark_object): Adapt code to extract pvectype. Use switch.
4268 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4270 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4271 Tighten new eassert a bit.
4273 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4275 Fix compilation with --enable-gcc-warnings and -O1
4277 * doprnt.c (doprnt): Change type of tem to int, initialize
4278 to avoid compiler warning. Add eassert.
4279 * search.c (simple_search): Initialize match_byte to avoid
4280 compiler warning. Add eassert.
4282 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4284 Avoid weird behavior with large horizontal scrolls.
4285 Without this change, for example, large hscroll values would
4286 mess up Emacs's display on Fedora 15 x86, presumably due to
4287 overflows in int calculations in the display code.
4288 Also, if buffers had long lines, Emacs would freeze.
4289 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4290 (set_window_hscroll): New function, containing the old guts of
4291 Fset_window_hscroll. Return the clipped value.
4292 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4293 This avoids the need to check against PTRDIFF_MAX.
4295 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4297 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4299 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4301 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4303 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4304 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4305 since GCC 4.4.6 issues a bogus warning for them.
4307 Fix bugs in file timestamp newness comparisons.
4308 * fileio.c (Ffile_newer_than_file_p):
4309 * lread.c (Fload): Use full timestamp resolution of files,
4310 not just the 1-second resolution, so that files that are only
4311 slightly newer still count as newer.
4312 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4313 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4315 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4317 * fileio.c: Improve handling of file time marker. (Bug#11852)
4318 (special_mtime): New function.
4319 (Finsert_file_contents, Fverify_visited_file_modtime):
4320 Use it to set special mtime values consistently.
4322 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4324 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4325 marker for non-existing file. (Bug#11852)
4327 2012-07-03 Glenn Morris <rgm@gnu.org>
4329 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4330 and did not make it into globals.h).
4332 2012-07-03 Tom Tromey <tromey@redhat.com>
4334 * window.c (Fset_window_margins, Fset_window_fringes)
4335 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4336 * textprop.c (Fprevious_property_change): No longer static.
4337 * syntax.c (Fsyntax_table_p): No longer static.

4358 * dispextern.h: Remove EXFUNs.
4359 * intervals.h: Remove EXFUNs.
4360 * fontset.h: Remove EXFUN.
4361 * font.h: Remove EXFUNs.
4362 * dosfns.c (system_process_attributes): Remove EXFUN.
4363 * keymap.h: Remove EXFUNs.
4364 * lisp.h: Remove EXFUNs.
4365 * w32term.h: Remove EXFUNs.
4366 * window.h: Remove EXFUNs.
4367 * xsettings.h: Remove EXFUN.
4368 * xterm.h: Remove EXFUN.
4370 2012-07-03 Glenn Morris <rgm@gnu.org>
4372 * lisp.h (Frandom): Make it visible to C.
4373 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4374 buffer for invisible buffers. (Bug#1229)
4376 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4378 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4379 values which aren't power of 2.
4380 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4381 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4384 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4386 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4388 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4390 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4392 * alloc.c (allocate_vector_block): Remove redundant
4393 calls to mallopt if DOUG_LEA_MALLOC is defined.
4394 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4395 avoid calls to mallopt if zero_vector is returned.
4397 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4399 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4400 is enabled, avoid dereferencing NULL current_sblock if
4403 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4405 Cleanup basic buffer management.
4406 * buffer.h (struct buffer): Change layout to use generic vector
4407 marking code. Fix some comments. Change type of 'clip_changed'
4408 to bitfield. Remove unused #ifndef old.
4409 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4410 (GET_OVERLAYS_AT): Fix indentation.
4411 (for_each_per_buffer_object_at): New macro.
4412 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4413 (Fbuffer_local_variables): Use it.
4414 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4415 * alloc.c (allocate_buffer): Adjust to match new layout of
4416 struct buffer. Fix comment.
4417 (mark_overlay): New function.
4418 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4419 Lisp area of struct buffer.
4420 (mark_object): Use it. Adjust marking of misc objects
4421 and related comments.
4423 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4425 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4426 wrapper that is not needed because the wrapped code is a no-op (zero
4427 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4428 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4430 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4432 * alloc.c (mark_buffer): Simplify. Remove prototype.
4433 (mark_object): Add comment. Reorganize marking of vector-like
4434 objects. Use CHECK_LIVE for all vector-like objects except buffers
4435 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4436 Avoid redundant calls to mark_vectorlike for bool vectors.
4438 2012-06-30 Glenn Morris <rgm@gnu.org>
4440 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4442 * epaths.in (PATH_SITELOADSEARCH): New.
4443 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4444 This is rather than relying on --enable-locallisppath elements
4445 having "site-lisp" in their names. (Bug#10208#25, 11658)
4447 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4449 * w32proc.c (sys_select): Accept and ignore one more argument.
4451 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4453 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4454 (pselect) [!MS_DOS]: Redirect to sys_select.
4456 * sysdep.c: Don't include dos.h and dosfns.h.
4458 * process.c (sys_select):
4459 * msdos.c (sys_select): Accept one more argument and ignore it.
4461 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4462 adapt data types and code to that.
4465 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4466 which clashes with the gnulib function of the same name.
4468 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4470 * font.c (font_style_to_value, font_style_symbolic)
4471 (font_prop_validate_style): Add type checks for values in
4474 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4476 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4479 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4481 * xdisp.c (try_window_id): Undo last change.
4483 * w32.c (getwd): Adjust commentary about startup_dir.
4484 (init_environment): Always call sys_access, even in non-MSVC
4485 builds. Don't chdir to the directory of the Emacs executable.
4486 This undoes code from 1997 which was justified by the need to
4487 "avoid conflicts when removing and renaming directories". But its
4488 downside was that every relative file name was being interpreted
4489 relative to the directory of the Emacs executable, which can never
4490 be TRT. In particular, it broke sys_access when called with
4491 relative file names.
4492 (sys_access): Map GetLastError to errno.
4494 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4496 * window.h (struct window): Change type of 'fringes_outside_margins'

4686 Use sprintf return value instead of invoking strlen on result.
4687 In the old days this wasn't portable, since some sprintf
4688 implementations returned char *. But they died out years ago and
4689 Emacs already assumes sprintf returns int.
4690 Similarly for float_to_string.
4691 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

4699 Use sprintf or float_to_string result to avoid need to call strlen.
4700 * data.c (Fnumber_to_string):
4701 Use make_unibyte_string, since the string must be ASCII.
4702 * lisp.h, print.c (float_to_string): Now returns int length.
4703 * term.c (produce_glyphless_glyph):
4704 Use sprintf result rather than recomputing it.
4706 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
4707 * Makefile.in (ALL_CFLAGS):
4708 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

4737 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
4739 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

4742 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
4744 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
4745 instead of truncating it to 63 (admittedly a generous limit).

4804 * dispnew.c (Fsleep_for, sit_for):
4805 * keyboard.c (kbd_buffer_get_event):
4806 * process.c (Faccept_process_output):
4807 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
4808 This improves on the previous patch, which introduced a bug
4809 when time_t is unsigned and as wide as intmax_t.
4810 See <http://bugs.gnu.org/9000#51>.
4812 2012-06-23 Eli Zaretskii <eliz@gnu.org>
4814 * dispnew.c (sit_for, Fsleep_for):
4815 * keyboard.c (kbd_buffer_get_event):

4829 Privately reported by Herbert J. Skuhra.
4830 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

4875 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
4877 Support higher-resolution time stamps (Bug#9000).
4878 The time stamps are only nanosecond-resolution at the C level,
4879 since that's the best that any real-world system supports now.
4880 But they are picosecond-resolution at the Lisp level, as that's
4881 easy, and leaves room for future OS improvements.
4883 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
4886 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
4887 Don't get current time unless it's needed.
4889 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
4890 now provides it if it's absent.
4891 (start_atimer): Port to higher-res time stamps.
4892 Check for time stamp overflow. Don't get current time more
4893 often than is needed.
4895 * buffer.h (struct buffer): Buffer modtime now has high resolution.
4896 Include systime.h, not time.h.
4897 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
4899 * dired.c: Include stat-time.h.
4900 (Ffile-attributes): File times now have higher resolution.
4902 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
4903 (struct image): Timestamp now has higher resolution.
4905 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
4906 has at least microseconds now. All uses removed.
4907 (update_frame, update_single_window, update_window, update_frame_1)
4908 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
4909 (duration_to_sec_usec): Remove; no longer needed.
4911 * editfns.c (time_overflow): Now extern.
4912 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
4913 (float-time, Fformat_time_string, Fcurrent_time_string)
4914 (Fcurrent_time_zone): Accept and generate higher-resolution
4916 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
4917 (decode_time_components, lisp_seconds_argument): New functions.
4918 (make_time): Now static.
4919 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
4920 Report an error if the time is invalid, rather than having the caller
4923 * fileio.c: Include <stat-time.h>
4924 (Fcopy_file): Copy higher-resolution time stamps.
4925 Prefer to set the time stamp via a file descriptor if that works.
4926 (Fset_file_times, Finsert_file_contents, Fwrite_region)
4927 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
4928 (Fvisited_file_modtime, Fset_visited_file_modtime):
4929 Support higher-resolution time stamps.
4931 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
4933 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
4935 * image.c (prepare_image_for_display, clear_image_cache)
4936 (lookup_image): Port to higer-resolution time stamps.
4938 * keyboard.c (start_polling, bind_polling_period):
4939 Check for time stamp overflow.
4940 (read_char, kbd_buffer_get_event, timer_start_idle)
4941 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
4942 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
4943 Port to higher-resolution time stamps. Do not assume time_t is signed.
4944 (decode_timer): New function. Timers are now vectors of length 9,
4945 not 8, to accommodate the picosecond component.
4946 (timer_check_2): Use it.
4948 * nsterm.m (select_timeout, timeval_subtract): Remove.
4949 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
4950 as they're a bit more accurate and handle overflow better.
4951 (ns_select): Change prototype to be compatible with pselect.
4952 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
4953 * nsterm.h (ns_select): Adjust prototype.
4955 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
4956 us-resolution time stamps.
4957 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
4959 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
4961 * lisp.h (time_overflow): New decl.
4962 (wait_reading_process_output): First arg is now intmax_t, not int,
4963 to accommodate larger waits.
4965 * process.h (struct Lisp_Process.read_output_delay):
4966 Now counts nanoseconds, not microseconds.
4967 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
4969 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
4970 (wait_reading_process_output):
4971 Port to ns-resolution time stamps.
4972 (Faccept_process_output, wait_reading_process_output):
4973 Check for time stamp overflow. Do not assume time_t is signed.
4974 (select_wrapper): Remove; we now use pselect.
4975 (Fprocess_attributes): Now generates ns-resolution time stamps.
4977 * sysdep.c: Include utimens.h. Don't include utime.h
4978 or worry about struct utimbuf; gnulib does that for us now.
4979 (gettimeofday): Remove; gnulib provides a substitute.
4980 (make_timeval): New function.
4981 (set_file_times): Now sets ns-resolution time stamps.
4982 New arg FD; all uses changed.
4983 (time_from_jiffies, ltime_from_jiffies, get_up_time)
4984 (system_process_attributes):
4985 Now returns ns-resolution time stamp. All uses changed.
4986 Check for time stamp overflow.
4988 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
4989 provides a substitute now.
4991 * systime.h: Include timespec.h rather than sys/time.h and time.h,
4992 since it guarantees struct timespec.
4993 (EMACS_TIME): Now struct timespec, so that we can support
4994 ns-resolution time stamps.
4995 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4996 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4997 (EMACS_USECS): Remove.
4998 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4999 so multiply the arg by 1000 before storing it.

5002 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

5009 (make_timeval, make_lisp_time, decode_time_components): New decls.
5010 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5011 that it mishandled time_t overflow. You can't compare by subtracting!
5012 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5013 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

5041 (timeval_subtract): Remove; no longer needed.
5042 (XTflash, XTring_bell, x_wait_for_event):
5043 Port to ns-resolution time stamps. Don't assume time_t is signed.

5052 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5053 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5054 staticidx goes up to 1597 out of 1600 = 0x640.)

5058 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
5059 Otherwise, the umask might be mistakenly 0 while handling input signals.

5092 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
5093 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
5094 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
5095 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

5104 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
5105 gets killed during executing of this function (Bug#11665).
5106 Try to always return Qt when the buffer has been actually killed.
5107 (Vkill_buffer_query_functions): In doc-string say that functions
5108 run by this hook should not change the current buffer.
5110 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

5135 argument were confusing, as 'eassert' typically does not evaluate
5138 * coding.c (produce_chars): Use ptrdiff_t, not int.
5140 * xterm.c (x_draw_underwave): Check for integer overflow.
5141 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5459 (all_vectors): Rename to `large_vectors'.
5460 (allocate_vector_from_block, init_vectors, allocate_vector_from_block)
5461 (sweep_vectors): New functions.
5462 (allocate_vectorlike): Return `zero_vector' as the only vector of
5463 0 items. Allocate new vector from block if vector size is less than
5464 or equal to VBLOCK_BYTES_MAX.
5465 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
5466 (init_alloc_once): Add call to init_vectors.
5468 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
5470 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
5472 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
5474 * doprnt.c (doprnt): Truncate multibyte char correctly.
5475 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5476 would mishandle a string argument "Xc" if X was a multibyte
5477 character of length 2: it would truncate after X's first byte
5478 rather than including all of X.
5480 2012-06-06 Chong Yidong <cyd@gnu.org>
5482 * buffer.c (word_wrap): Doc fix.
5484 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
5486 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

5502 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
5505 2012-06-03 Chong Yidong <cyd@gnu.org>
5507 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5508 (note_mode_line_or_margin_highlight): If there is no help echo,
5509 use mode-line-default-help-echo. Handle the case where the mouse
5510 position is past the end of the mode line string.
5512 * buffer.c (buffer_local_value_1): New function, split from
5513 Fbuffer_local_value; can return Qunbound.
5514 (Fbuffer_local_value): Use it.
5515 (Vmode_line_format): Docstring tweaks.
5517 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5519 * sysdep.c (system_process_attributes): Improve comment.
5521 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
5523 * keyboard.c: Export real-this-command to Elisp.
5524 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
5525 and DEFVAR it. Update all users.
5527 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5529 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5531 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5532 Convert pctcpu and pctmem to Lisp float properly.
5533 Let the compiler fold better, as 100.0/0x8000 is exact.
5535 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5537 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5540 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5542 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5544 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5546 For a 'struct window', replace some Lisp_Object fields to
5547 bitfields where appropriate, remove unused fields.
5548 * window.h (struct window): Remove unused 'last_mark_x' and
5549 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5550 change it's type from Lisp_Object to bitfield.
5551 Change type of 'force_start', 'optional_new_start',
5552 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5553 fields from Lisp_Object to bitfield. Adjust users accordingly.
5555 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5557 Pacify gcc -Wdouble-precision when using Xaw.
5558 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5559 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5560 Use 'float' consistently, rather than 'float' in most places
5561 and 'double' in a couple of places.
5563 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5565 * xdisp.c (handle_stop): Detect whether we have overlay strings
5566 loaded by testing it->current.overlay_string_index to be
5567 non-negative, instead of checking whether n_overlay_strings is
5568 positive. (Bug#11587)
5570 2012-05-31 Chong Yidong <cyd@gnu.org>
5572 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5574 * doc.c (Fsubstitute_command_keys): Doc fix.
5576 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5578 * search.c (search_buffer): Remove calls to
5579 r_alloc_inhibit_buffer_relocation, as it is now called by
5580 maybe_unify_char, which was the cause of relocation of buffer text
5583 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5585 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5586 for the duration of call to load_charset, to avoid problems with
5587 callers of maybe_unify_char that access buffer text through C
5590 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5591 decrement the inhibition flag, instead of just setting or
5594 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5596 Remove obsolete '#define static' cruft.
5597 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5598 This #undef was "temporary" in 2000; it is no longer needed
5599 now that '#define static' has gone away.
5600 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5601 (gray_bitmap_bits): Remove; no longer needed.
5602 All uses replaced with definiens.
5603 * xterm.c: Include "bitmaps/gray.xbm".
5605 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5607 Clean up __executable_start, monstartup when --enable-profiling.
5608 The following changes affect the code only when profiling.
5609 * dispnew.c (__executable_start): Rename from safe_bcopy.
5610 Define only on platforms that need it.
5611 * emacs.c: Include <sys/gmon.h> when profiling.
5612 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5613 (__executable_start): Remove decl, since lisp.h does it now.
5614 (safe_bcopy): Remove decl; no longer has that name.
5615 (main): Coalesce #if into single bit of code, for simplicity.
5616 Cast pointers to uintptr_t, since standard libraries want integers
5618 * lisp.h (__executable_start): New decl.
5620 2012-05-31 Glenn Morris <rgm@gnu.org>
5622 * image.c (Fimagemagick_types): Doc fix.
5624 2012-05-30 Jim Meyering <meyering@redhat.com>
5626 * callproc.c (Fcall_process_region): Include directory component
5627 in mkstemp error message (Bug#11586).

5631 * alloc.c, lisp.h (make_pure_vector): Now static.
5633 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

5636 Move to byte-run.el.
5637 (Fautoload): Do the hash-doc more carefully.
5638 * data.c (Fdefalias): Purify definition, except for keymaps.
5639 (Qdefun): Move from eval.c.
5640 * lisp.h (Qdefun): Remove.
5641 * lread.c (read1): Tiny simplification.
5643 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
5645 Do not create empty overlays with the evaporate property (Bug#9642).
5646 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
5647 Bug#9642, but explicitly check that the buffer the overlay would
5648 be moved to is live and rearrange lines to make sure that errors
5649 will not put the overlay in an inconsistent state.
5650 (Fdelete_overlay): Cosmetics.
5652 2012-05-28 Eli Zaretskii <eliz@gnu.org>
5654 * w32term.c (my_bring_window_to_top): New function.
5655 (x_raise_frame): Use handle returned by DeferWindowPos, which
5656 could be different from the original one.
5657 Call my_bring_window_to_top instead of my_set_foreground_window.
5660 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
5661 by calling BringWindowToTop.
5663 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
5664 (WM_EMACS_END): Increase by one.
5666 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
5668 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
5669 This avoids undefined behavior that might cause the eassert
5670 to not catch an out-of-range value.
5672 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
5674 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
5675 Update dependencies.
5677 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5679 * bidi.c (bidi_mirror_char): Fix last change.
5681 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
5683 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
5684 when referring to sectname field in printf format.
5686 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
5688 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
5689 Only r_alloc_inhibit_buffer_relocation needed to be added;
5690 the others were already declared.
5692 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
5693 before checking whether it's out of range. Put the check inside
5695 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
5697 2012-05-27 Ken Brown <kbrown@cornell.edu>
5699 * callproc.c (Fcall_process): Restore a line that was accidentally
5700 commented out in the 2011-02-13 change (bug#11547).
5702 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5704 * lisp.h [REL_ALLOC]: Add prototypes for external functions
5705 defined on ralloc.c.
5707 * buffer.c [REL_ALLOC]: Remove prototypes of
5708 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
5709 they are now on lisp.h.
5711 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
5713 * search.c (search_buffer): Use it to inhibit relocation of buffer
5714 text while re_search_2 is doing its job, because re_search_2 is
5715 passed C pointers to buffer text. (Bug#11519)
5717 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
5720 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
5721 state after an additional call to move_it_in_display_line_to, keep
5722 the values of it->max_ascent and it->max_descent found for the
5724 (pos_visible_p): Revert the comparison against bottom_y to what it
5725 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
5728 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5730 Fix coding-related core dumps with gcc -ftrapv.
5731 The code was computing A - B, where A and B are pointers, and B is
5732 random garbage. This can lead to core dumps on platforms that
5733 have special pointer registers, and it also leads to core dumps on
5734 x86-64 when compiled with gcc -ftrapv. The fix is to compute
5735 A - B only when B is initialized properly.
5736 * coding.c (coding_set_source, coding_set_destination): Return void.
5737 (coding_change_source, coding_change_destinations): New functions,
5738 with the old behaviors of coding_set_source and coding_set_destination.
5739 All callers that need an offset changed to use these new functions.
5741 2012-05-26 Glenn Morris <rgm@gnu.org>
5743 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
5745 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5747 Extend mouse support on W32 text-mode console.
5748 * xdisp.c (draw_row_with_mouse_face):
5749 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
5751 * w32console.c: Include window.h.
5752 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
5754 (initialize_w32_display): Initialize mouse-highlight data.
5756 * w32inevt.c: Include termchar.h and window.h.
5757 (do_mouse_event): Support mouse-autoselect-window. When the mouse
5758 moves, call note_mouse_highlight. If help_echo changed, call
5759 gen_help_event to produce help-echo message in the echo area.
5760 Call clear_mouse_face if mouse_face_hidden is set in the mouse
5763 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5765 * lread.c (read1): Simplify slightly to avoid an overflow warning
5766 with GCC 4.7.0 on x86-64.
5768 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5770 * bidi.c (bidi_mirror_char): Revert last change: an int is
5771 definitely wide enough here.
5773 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
5775 Fix integer width and related bugs (Bug#9874).
5776 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
5777 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
5778 (string_bytes, check_sblock, allocate_string_data):
5779 (compact_small_strings, Fmake_bool_vector, make_string)
5780 (make_unibyte_string, make_multibyte_string)
5781 (make_string_from_bytes, make_specified_string)
5782 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
5783 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
5785 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5786 (allocate_pseudovector):
5787 Use int, not EMACS_INT, where int is wide enough.
5788 (inhibit_garbage_collection, Fgarbage_collect):
5789 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5790 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
5791 int might not be wide enough.
5792 (bidi_cache_search, bidi_cache_find, bidi_init_it)
5793 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5794 (bidi_at_paragraph_end, bidi_find_paragraph_start)
5795 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
5796 (bidi_level_of_next_char, bidi_move_to_visually_next):
5797 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5798 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
5799 (Fkill_buffer, Fset_buffer_major_mode)
5800 (advance_to_char_boundary, Fbuffer_swap_text)
5801 (Fset_buffer_multibyte, overlays_at, overlays_in)
5802 (overlay_touches_p, struct sortvec, record_overlay_string)
5803 (overlay_strings, recenter_overlay_lists)
5804 (adjust_overlays_for_insert, adjust_overlays_for_delete)
5805 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
5806 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
5807 (Foverlay_recenter, last_overlay_modification_hooks_used)
5808 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
5809 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5810 (validate_region): Omit unnecessary test for b <= e,
5811 since that's guaranteed by the previous test.
5812 (adjust_overlays_for_delete): Avoid pos + length overflow.
5813 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
5814 (report_overlay_modification):
5815 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5816 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
5817 Omit pointer cast, which isn't needed anyway, and doesn't work
5818 after the EMACS_INT -> ptrdiff_t change.
5819 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
5820 * buffer.h: Adjust decls to match defn changes elsewhere.
5821 (struct buffer_text, struct buffer):
5822 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5823 Use EMACS_INT, not int, where int might not be wide enough.
5824 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
5825 not int, to avoid needless 32-bit limit on 64-bit hosts.
5826 (exec_byte_code): Use tighter memory-full test, one that checks
5827 for alloca overflow. Don't compute the address of the object just
5828 before an array, as that's not portable. Use EMACS_INT, not
5829 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
5830 * callint.c (Fcall_interactively):
5831 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5832 * callproc.c (call_process_kill, Fcall_process):
5833 Don't assume pid_t fits into an Emacs fixnum.
5834 (call_process_cleanup, Fcall_process, child_setup):
5835 Don't assume pid_t fits into int.
5836 (call_process_cleanup, Fcall_process, delete_temp_file)
5837 (Fcall_process_region):
5838 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5839 (Fcall_process): Simplify handling of volatile integers.
5840 Use int, not EMACS_INT, where int will do.
5841 * casefiddle.c (casify_object, casify_region, operate_on_word)
5842 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
5843 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5844 (casify_object): Avoid integer overflow when overallocating buffer.
5845 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
5846 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
5847 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
5848 * category.h (CATEGORYP): Don't assume arg is nonnegative.
5849 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
5850 integers are now checked earlier. All uses replaced with XINT.
5852 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5853 For CCL_MapSingle, check that content and value are in int range.
5854 (ccl_driver, Fregister_code_conversion_map):
5855 Check that Vcode_version_map_vector is a vector.
5856 (resolve_symbol_ccl_program): Check that vector header is in range.
5857 Always copy the vector, so that we can check its contents reliably
5858 now rather than having to recheck each instruction as it's being
5859 executed. Check that vector words fit in 'int'.
5860 (ccl_get_compiled_code, Fregister_ccl_program)
5861 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
5862 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
5863 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
5864 contents are in range.
5865 (Fccl_execute_on_string): Check that status is in range.
5866 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
5867 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
5868 Accept and return EMACS_INT, not int, because callers can pass values
5870 (c_string_width, strwidth, lisp_string_width, chars_in_text)
5871 (multibyte_chars_in_text, parse_str_as_multibyte)
5872 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
5873 (str_as_unibyte, str_to_unibyte, string_count_byte8)
5874 (string_escape_byte8, Fget_byte):
5875 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5876 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
5877 avoid mishandling large integers.
5878 * character.h: Adjust decls to match defn changes elsewhere.
5879 * charset.c (load_charset_map_from_file, find_charsets_in_text)
5880 (Ffind_charset_region):
5881 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5882 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
5883 (load_charset_map_from_vector, Fdefine_charset_internal):
5884 Don't assume fixnum fits in int.
5885 (load_charset_map_from_vector, Fmap_charset_chars):
5886 Remove now-unnecessary CHECK_NATNUMs.
5887 (Fdefine_charset_internal): Check ranges here, more carefully.
5888 Don't rely on undefined behavior with signed left shift overflow.
5889 Don't assume unsigned int fits into fixnum, or that fixnum fits
5890 into unsigned int. Don't require max_code to be a valid fixnum;
5891 that's not true for gb10830 4-byte on a 32-bit host. Allow
5892 invalid_code to be a cons, for the same reason. Require code_offset
5893 to be a character. Avoid int overflow if max_char is close
5895 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
5896 this is intended anyway and avoids some undefined behavior.
5897 (load_charset_map): Pass unsigned, not int, as 2nd arg of
5898 INDEX_TO_CODE_POINT, as that's what it expects.

6609 * lisp.h (USE_LSB_TAG):
6610 * mem-limits.h (EXCEEDS_LISP_PTR):
6611 Use VAL_MAX, not VALBITS, in #if.
6612 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
6613 (EMACS_UINT): Define unconditionally now.
6614 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
6615 (BITS_PER_EMACS_INT): New constants, replacing
6616 what used to be in config.h, but not useful in #if.
6617 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
6618 define them any more.
6619 (VAL_MAX): New macro.
6621 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
6622 BITS_PER_EMACS_INT, in #if.
6623 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
6624 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
6625 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
6626 * s/ms-w32.h (DATA_START):
6627 Move here from removed file m/intel386.h.
6628 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
6629 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
6631 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
6633 Assume C89 or later.
6634 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
6635 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
6637 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
6638 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
6639 * textprop.c, tparam.c (NULL): Remove.
6640 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
6641 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
6642 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
6643 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
6644 * xterm.c (input_signal_count): Assume volatile works.
6646 2012-05-21 Ken Brown <kbrown@cornell.edu>
6648 * xgselect.c (xg_select): Fix first argument in call to 'select'
6651 2012-05-20 Ken Brown <kbrown@cornell.edu>
6653 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
6654 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
6656 2012-05-19 Ken Brown <kbrown@cornell.edu>
6658 * xfns.c (x_in_use): Remove `static' qualifier.
6659 * xterm.h (x_in_use): Declare.
6660 * xgselect.c: Include xterm.h.
6661 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
6662 and `display_arg' (bug#9754).
6664 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
6666 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
6668 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
6669 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
6671 2012-05-18 Eli Zaretskii <eliz@gnu.org>
6673 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
6675 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
6676 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
6678 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
6679 reference to image_cache->refcount.
6680 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
6682 2012-05-17 Juri Linkov <juri@jurta.org>
6684 * search.c (Fword_search_regexp, Fword_search_backward)
6685 (Fword_search_forward, Fword_search_backward_lax)
6686 (Fword_search_forward_lax): Move functions to isearch.el
6687 (bug#10145, bug#11381).
6689 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
6691 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
6693 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
6695 * lread.c (init_obarray): Declare Qt and Qnil as special.
6697 2012-05-14 Glenn Morris <rgm@gnu.org>
6699 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
6700 Put "libexec" before "bin", for the sake of init_callproc_1.
6702 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6704 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
6706 * unexaix.c: Port to more-recent AIX compilers.
6707 (report_error, report_error_1, make_hdr, copy_sym)
6708 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
6709 Make arguments const char *, not char *, to avoid violations of C
6710 standard and to fix some AIX warnings reported by Gilles Pion.
6712 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6714 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
6715 already have overlays loaded.
6716 (handle_single_display_spec): Before returning without displaying
6717 fringe bitmap, synchronize the bidi iterator with the main display
6718 iterator, by calling iterate_out_of_display_property.
6719 (iterate_out_of_display_property): Detect buffer iteration by
6720 testing that it->string is a Lisp string.
6721 (get_next_display_element): When the current object is exhausted,
6722 and there's something on it->stack, call set_iterator_to_next to
6723 proceed with what's on the stack, instead of returning zero.
6724 (set_iterator_to_next): If called at the end of a Lisp string,
6725 proceed to consider_string_end without incrementing string
6726 position. Don't increment display vector index past the end of
6727 the display vector. (Bug#11417)
6728 (pos_visible_p): Don't report a position visible when move_it_to
6729 stopped at the last line of window, which happens to be scanned
6730 backwards by the bidi iteration. (Bug#11464)
6732 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6734 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
6735 and right-margin display specs even if the spec is invalid or we
6736 are on a TTY, and thus unable to display on the fringes.
6737 That's because the text with the property will not be displayed anyway,
6738 so we need to signal to the caller that this is a "replacing"
6739 display spec. This fixes display when the spec is invalid or we
6742 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6744 * unexaix.c (make_hdr): Fix typo in prototype.
6745 This bug broke the build on AIX. Problem reported by Gilles Pion.
6747 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
6749 * keyboard.c (kbd_buffer_get_event): Read special events also in
6750 batch mode. (Bug#11415)
6752 2012-05-12 Glenn Morris <rgm@gnu.org>
6754 * ns.mk: Update for ns_appbindir no longer having trailing "/".
6756 2012-05-12 Eli Zaretskii <eliz@gnu.org>
6758 * lisp.mk (lisp): Add newcomment.elc.
6760 2012-05-12 Glenn Morris <rgm@gnu.org>
6762 * Makefile.in (MKDIR_P): New, set by configure.
6763 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
6765 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
6767 Remove unused function hourglass_started.
6768 * dispextern.h (hourglass_started):
6769 * w32fns.c (hourglass_started):
6770 * xdisp.c (hourglass_started): Remove.
6772 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
6774 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
6775 Update dependencies.
6777 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
6779 * xgselect.c (xg_select): Put maxfds+1 into a var.
6780 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
6782 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
6784 2012-05-10 Dave Abrahams <dave@boostpro.com>
6786 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
6787 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
6789 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
6791 * dbusbind.c (xd_registered_buses): New internal Lisp object.
6792 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
6793 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
6794 Initialize xd_registered_buses.
6796 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
6798 Untag more efficiently if USE_LSB_TAG.
6799 This is based on a proposal by YAMAMOTO Mitsuharu in
6800 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
6801 For an admittedly artificial (nth 8000 longlist) benchmark on
6802 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
6803 Emacs's overall text size by 1%.
6804 * lisp.h (XUNTAG): New macro.
6805 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
6806 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
6807 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
6808 * eval.c (Fautoload):
6809 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
6810 * frame.h (XFRAME): Use XUNTAG.
6812 Port recent dbusbind.c changes to 32-bit --with-wide-int.
6813 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
6814 Remove unportable assumptions about print widths of types like
6816 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
6817 intptr_t when converting between pointer and integer, to avoid GCC
6818 warnings about wrong width.
6820 2012-05-09 Eli Zaretskii <eliz@gnu.org>
6822 * w32proc.c (new_child): Force Windows to reserve only 64KB of
6823 stack for each reader_thread, instead of defaulting to 8MB
6824 determined by the linker. This avoids failures in creating
6825 subprocesses on Windows 7, see the discussion in this thread:
6826 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
6828 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
6830 Fix up display of the *Minibuf-0* buffer in the mini window.
6831 * keyboard.c (read_char): Don't clear the echo area if there's no
6833 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
6834 contents of *Minibuf-0*) if there's no message displayed in its stead.
6836 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
6838 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
6841 2012-05-06 Chong Yidong <cyd@gnu.org>
6843 * lisp.mk (lisp): Update.
6845 2012-05-05 Jim Meyering <meyering@redhat.com>
6847 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
6849 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
6851 * data.c (PUT_ERROR): New macro.
6852 (syms_of_data): Use it. Add new error type `user-error'.
6853 * undo.c (user_error): New function.
6854 (Fprimitive_undo): Use it.
6855 * print.c (print_error_message): Adjust print style for `user-error'.
6856 * keyboard.c (user_error): New function.
6857 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
6859 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
6861 Do not limit current-time-string to years 1000..9999.
6862 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
6863 (Fcurrent_time_string): Support any year that is supported by the
6864 underlying localtime representation. Don't use asctime, as it
6865 has undefined behavior for years outside the range -999..9999.
6867 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
6869 Fix race conditions involving setenv, gmtime, localtime, asctime.
6870 Without this fix, interrupts could mess up code that uses these
6871 nonreentrant functions, since setting TZ invalidates existing
6872 tm_zone or tzname values, and since most of these functions return
6873 pointers to static storage.
6874 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
6875 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
6876 Grow the critical sections to include not just invoking
6877 localtime/gmtime, but also accessing these functions' results
6878 including their tm_zone values if any, and any related TZ setting.
6879 (format_time_string): Last arg is now struct tm *, not struct tm **,
6880 so that the struct tm is saved in the critical section.
6881 All callers changed. Simplify allocation of initial buffer, partly
6882 motivated by the fact that memory allocation needs to be outside
6883 the critical section.
6885 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
6887 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
6888 with RESET_INTERVAL.
6890 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
6891 Remove duplicated buffer name initialization.
6893 2012-05-02 Jim Meyering <jim@meyering.net>
6895 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
6897 * xfns.c (x_window): Use xstrdup (Bug#11375).
6899 2012-05-02 Eli Zaretskii <eliz@gnu.org>
6901 * xdisp.c (pos_visible_p): If already at a newline from the
6902 display string before the 'while' loop, don't walk back the glyphs
6903 from it3.glyph_row. Solves assertion violation when the display
6904 string begins with a newline (egg.el). (Bug#11367)
6906 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
6908 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
6911 2012-05-01 Glenn Morris <rgm@gnu.org>
6913 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
6914 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
6915 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
6916 All were removed before 23.1.
6918 * dispnew.c: Remove HAVE_LIBNCURSES test;
6919 it is always true on relevant platforms.
6921 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
6922 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
6924 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
6926 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
6928 * .gdbinit (xpr): Remove checks for no longer existing misc types.
6929 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
6932 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
6934 Do not avoid creating empty evaporating overlays (Bug#9642).
6935 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
6936 That is, do not delete an evaporating overlay if it becomes
6937 empty after its bounds are adjusted to fit within its buffer.
6938 This fix caused other problems, and I'm reverting it until we get
6939 to the bottom of them.
6941 2012-04-27 Chong Yidong <cyd@gnu.org>
6943 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
6945 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6947 * xdisp.c (pos_visible_p): If the window start position is beyond
6948 ZV, start the display from buffer beginning. Prevents assertion
6949 violation in init_iterator when the minibuffer window is scrolled
6952 * window.c (window_scroll_pixel_based): Likewise.
6954 2012-04-27 Chong Yidong <cyd@gnu.org>
6956 * keymap.c (where_is_internal): Doc fix (Bug#10872).
6958 2012-04-27 Glenn Morris <rgm@gnu.org>
6960 * fileio.c (Fcopy_file, Fset_file_selinux_context):
6961 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
6963 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6965 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
6966 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
6968 2012-04-26 Eli Zaretskii <eliz@gnu.org>
6970 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
6971 display element, check also the underlying string or buffer
6972 character. (Bug#11341)
6974 * w32menu.c: Include w32heap.h.
6975 (add_menu_item): If the call to AppendMenuW (via
6976 unicode_append_menu) fails, disable Unicode menus only if we are
6977 running on Windows 9X/Me.
6979 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6981 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6982 (xgetint): Add missing shift for LSB tags.
6984 2012-04-24 Martin Rudalics <rudalics@gmx.at>
6986 * keyboard.c (read_char): Don't wipe echo area for select window
6987 events: These might get delayed via `mouse-autoselect-window'
6990 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
6992 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
6993 manipulation of :loaded-from data.
6995 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6997 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6998 now a cons (bug#11311).
7000 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7002 Do not create empty overlays with the evaporate property (Bug#9642).
7003 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7004 if it becomes empty after its bounds are adjusted to fit within
7005 its buffer. Without this fix, in a nonempty buffer (let ((o
7006 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7007 yields an empty overlay that has the evaporate property, which is
7008 not supposed to happen.
7010 Fix minor GTK3 problems found by static checking.
7011 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7012 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7013 (struct _EmacsFixedClass, emacs_fixed_get_type):
7014 Move decls here from emacsgtkfixed.h, since they needn't be public.
7015 (emacs_fixed_get_type): Now static.
7016 (emacs_fixed_class_init): Omit unused local.
7017 (emacs_fixed_child_type): Remove; unused.

7019 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7020 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7021 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7022 (EMACS_FIXED_GET_CLASS): Remove; unused.
7023 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
7025 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
7026 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7028 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7030 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7031 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7032 (__malloc_size_t, __malloc_ptrdiff_t):
7033 Remove. All uses removed, replaced by the definiens if needed,
7034 since we can assume C89 or better now.
7035 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7036 (protect_malloc_state, align, get_contiguous_space)
7037 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7038 (malloc_atfork_handler_child, malloc_enable_thread)
7039 (malloc_initialize_1, __malloc_initialize, morecore_nolock)

7041 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
7042 (special_realloc, _realloc_internal_nolock, _realloc_internal)
7043 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7044 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7045 Define using prototypes, not old style.
7046 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7047 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7048 (align): Don't assume that signed integer overflow wraps around.
7049 Omit unused local var.
7050 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7051 (_free_internal_nolock, memalign, mallochook, reallochook):
7052 Omit no-longer-needed casts.
7053 (valloc): Use getpagesize, not __getpagesize.
7054 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7055 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7057 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.

7112 since the two debugging options are incompatible.
7113 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7115 (mem_init, mem_insert, mem_insert_fixup):
7116 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7284 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7285 against is gone. It's better to use vfork now so that when Cygwin
7286 gains a new, working vfork, we use it automatically (bug#10398).

7343 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7345 * xdisp.c (set_cursor_from_row): If the display string appears in
7346 the buffer at position that is closer to point than the position
7347 after the display string, display the cursor on the first glyph of
7348 the display string. Fixes cursor display when a 'display' text
7349 property immediately follows invisible text. (Bug#11094)
7351 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7353 composite.c: use 'double' consistently
7354 * composite.c (get_composition_id): Use 'double' consistently
7355 instead of converting 'float' to 'double' and vice versa; this is

7405 [!WINDOWSNT]: New macros.
7406 (init_libxml2_functions, libxml2_loaded_p): New functions.
7407 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7408 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7409 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.

7430 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7431 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7432 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7433 macros related to unification of CJK characters. For the details,
7434 see the discussion following the message here:
7435 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

7454 position we get to after a call to move_it_to fails the
7455 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7456 only if we wind up in a string from display property. (Bug#11063)
7458 * window.c (Fdelete_other_windows_internal): Invalidate the row
7459 and column information about mouse highlight, so that redisplay
7460 restores it after reallocating the glyph matrices. (Bug#7464)
7462 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7463 string comes from a `display' text property, use the buffer
7464 position of that property as if we actually saw that position in
7466 (move_it_by_lines): Remove the assertion that
7467 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7468 violated when there's a before-string at the beginning of a line.
7471 2012-03-30 Eli Zaretskii <eliz@gnu.org>

7528 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7529 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7530 when fetching a multibyte character consumes more bytes than
7531 CHAR_BYTES returns, due to unification of CJK characters in
7532 string_char. (Bug#11073)
7534 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7536 * process.c (wait_reading_process_output): Handle pty disconnect
7537 by refraining from sending oneself a SIGCHLD (bug#10933).
7539 2012-03-22 Chong Yidong <cyd@gnu.org>

7554 * w32proc.c (Fw32_set_console_codepage)
7555 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
7558 2012-03-20 Chong Yidong <cyd@gnu.org>
7560 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
7561 to reflect default non-nil value of redisplay-dont-pause.
7563 2012-03-19 Kenichi Handa <handa@m17n.org>
7565 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
7566 it fit in a valid range (Bug#11003).
7568 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7570 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7571 that is not from display property, accept the row as a "cursor
7572 row" if one of the string's character has a non-nil `cursor'
7573 property. Fixes cursor positioning when there are newlines in
7574 overlay strings, e.g. in icomplete.el. (Bug#11035)
7576 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
7578 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
7580 2012-03-12 Chong Yidong <cyd@gnu.org>
7582 * eval.c (inhibit_lisp_code): Rename from
7583 inhibit_window_configuration_change_hook; move from window.c.
7585 * xfns.c (unwind_create_frame_1, Fx_create_frame):
7586 * window.c (run_window_configuration_change_hook)
7587 (syms_of_window): Callers changed.

7602 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
7604 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
7606 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
7607 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7610 2012-03-03 Glenn Morris <rgm@gnu.org>
7612 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
7614 2012-03-02 Eli Zaretskii <eliz@gnu.org>
7616 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
7617 position past the first glyph_row that ends at ZV. (Bug#10902)
7618 (redisplay_window, next_element_from_string): Fix typos in
7620 (redisplay_window): Pass to move_it_vertically the margin in
7621 pixels, not in screen lines.
7623 2012-03-02 Glenn Morris <rgm@gnu.org>
7625 * buffer.c (buffer-list-update-hook): Doc fix.
7627 2012-02-29 Eli Zaretskii <eliz@gnu.org>

7630 push_it before setting up the iterator for the first overlay
7631 string, even if we have an empty string loaded.
7632 (next_overlay_string): If there's an empty string on the iterator
7633 stack, pop the stack. (Bug#10903)
7635 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
7637 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
7638 Suggested by Stefan Monnier in
7639 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
7640 * alloc.c (widen_to_Lisp_Object): New static function.
7641 (mark_memory): Also mark Lisp_Objects by fetching pointer words
7642 and widening them to Lisp_Objects. This would work even if
7643 USE_LSB_TAG is defined and wide integers are used, which might
7644 happen in a future version of Emacs.
7646 2012-02-25 Chong Yidong <cyd@gnu.org>
7648 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
7651 * xselect.c (Fx_selection_exists_p): Doc fix.
7652 (x_clipboard_manager_save_all): Print an informative message
7653 before saving to clipboard manager.
7655 2012-02-24 Chong Yidong <cyd@gnu.org>
7657 * keyboard.c (process_special_events): Handle all X selection
7658 requests in kbd_buffer, not just the next one (Bug#8869).
7660 2012-02-23 Chong Yidong <cyd@gnu.org>
7662 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
7663 call when setting menu-bar-lines and tool-bar-lines parameters.
7664 (unwind_create_frame_1): New helper function.
7666 * window.c (inhibit_window_configuration_change_hook): New var.
7667 (run_window_configuration_change_hook): Obey it.
7668 (syms_of_window): Initialize it.
7670 2012-02-22 Chong Yidong <cyd@gnu.org>
7672 * xterm.c (x_draw_image_relief): Add missing type check for
7673 Vtool_bar_button_margin (Bug#10743).
7675 2012-02-21 Chong Yidong <cyd@gnu.org>
7677 * fileio.c (Vfile_name_handler_alist): Doc fix.
7679 * buffer.c (Fget_file_buffer): Protect against invalid file
7680 handler return value.
7682 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
7684 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
7685 when computing $valmask.
7687 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
7688 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
7689 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
7690 It's useless in that case, and it can cause problems on hosts
7691 that allocate halves of EMACS_INT values separately.
7692 Reported by Dan Horák. Diagnosed by Andreas Schwab in
7693 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
7694 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
7695 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
7696 it avoids undefined behavior on hosts where shifting right by more
7697 than the word width has undefined behavior.
7699 2012-02-19 Chong Yidong <cyd@gnu.org>
7701 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
7702 (Funhandled_file_name_directory, Ffile_name_as_directory)
7703 (Fdirectory_file_name, Fexpand_file_name)

7721 2012-02-15 Chong Yidong <cyd@gnu.org>
7723 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
7724 marked as special. Also, starting docstrings with * is obsolete.
7726 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
7728 * gnutls.c (emacs_gnutls_write): Fix last change.
7730 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

7739 2012-02-12 Chong Yidong <cyd@gnu.org>
7741 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
7742 as that creates a dangerous corner case.
7744 * window.c (Fdelete_window_internal): Invalidate the mouse
7745 highlight (Bug#9904).
7747 2012-02-12 Glenn Morris <rgm@gnu.org>

7752 * nsselect.m (Fx_own_selection_internal)
7753 (Fx_disown_selection_internal, Fx_selection_exists_p)
7754 (Fx_selection_owner_p, Fx_get_selection_internal):
7755 Sync docs and argument specs with the xselect.c versions.

7773 2012-02-09 Kenichi Handa <handa@m17n.org>
7775 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
7777 2012-02-07 Chong Yidong <cyd@gnu.org>
7779 * buffer.c (Fbuffer_local_variables)
7780 (buffer_lisp_local_variables): Handle unbound vars correctly;
7781 don't let Qunbound leak into Lisp.
7783 2012-02-07 Glenn Morris <rgm@gnu.org>
7785 * image.c (Fimagemagick_types): Doc fix.
7787 * image.c (imagemagick-render-type): Change it from a lisp object
7788 to an integer. Move the doc here from the lisp manual.

7791 2012-02-06 Chong Yidong <cyd@gnu.org>
7793 * doc.c (store_function_docstring): Avoid applying docstring of
7794 alias to base function (Bug#2603).
7796 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
7798 * .gdbinit (pp1, pv1): Remove redundant defines.
7801 2012-02-04 Chong Yidong <cyd@gnu.org>

7820 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
7822 Handle overflow when computing char display width (Bug#9496).
7823 * character.c (char_width): Return EMACS_INT, not int.
7824 (char_width, c_string_width): Check for overflow when
7825 computing the width; this is possible now that individual
7826 characters can have unbounded width. Problem introduced
7827 by merge from Emacs 23 on 2012-01-19.
7829 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
7831 * dbusbind.c (Fdbus_register_method): Mention the return value

7844 2012-02-02 Kenichi Handa <handa@m17n.org>
7846 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
7847 0, do not call append_composite_glyph.

7851 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
7853 (x_produce_glyphs): If the component of a composition is a null
7854 string, set it->pixel_width to 1 to avoid zero-width glyph.

7858 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
7859 first 2 arguments are identical. This makes inserting large
7860 output from a subprocess an order of magnitude faster on
7861 MS-Windows, where all sbrk'ed memory is always contiguous.

7919 * character.c (char_width): New function.
7920 (Fchar_width, c_string_width, lisp_string_width):

7946 2012-01-11 Glenn Morris <rgm@gnu.org>
7948 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
7949 from load-path also when installation-directory is nil. (Bug#10208)
7951 2012-01-10 Glenn Morris <rgm@gnu.org>
7953 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

7960 * xdisp.c (rows_from_pos_range): Accept additional argument
7961 DISP_STRING, and accept any glyph in a row whose object is that
7962 string as eligible for mouse highlight. Fixes mouse highlight of
7963 display strings from overlays. (Bug#10464)
7965 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
7967 emacs: fix an auto-save permissions race condition (Bug#10400)
7968 * fileio.c (auto_saving_dir_umask): New static var.
7969 (Fmake_directory_internal): Use it.
7970 (do_auto_save_make_dir): Set it, instead of invoking chmod after
7971 creating the directory. The old code temporarily assigns
7972 too-generous permissions to the directory.
7973 (do_auto_save_eh): Clear it.
7974 (Fdo_auto_save): Catch all errors, not just file errors, so
7975 that the var is always cleared.
7977 2012-01-07 Eli Zaretskii <eliz@gnu.org>
7979 * search.c (scan_buffer): Pass character positions to
7980 know_region_cache, not byte positions. (Bug#6540)

8021 * xmenu.c (x_menu_wait_for_event): Use xg_select for Gtk3 so menus

8028 * callint.c (Fcall_interactively): Don't truncate prompt string.
8030 2011-12-23 Eli Zaretskii <eliz@gnu.org>
8032 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8033 property that ends at ZV, so that the bidi iteration could be

8480 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
8481 is set, removing the need for VIRT_ADDRESS_VARIES.
8482 (PURE_P): Use a more-efficient implementation that needs just one
8483 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

8497 (erase_phys_cursor, update_window_cursor, show_mouse_face)
8498 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8499 behave as if the cursor position were at the window margin.
8501 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8502 and the cursor position is out of bounds, behave as if the cursor
8503 position were at the window margin. (Bug#10075)
8505 2011-11-18 Chong Yidong <cyd@gnu.org>
8507 * window.c (Fwindow_combination_limit): Make first argument

8729 (static_offset_intervals): Remove.
8730 (offset_intervals): Rewrite using the old contents of
8731 static_offset_intervals. The old version didn't conform to C99

8992 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
8994 2011-10-27 Chong Yidong <cyd@gnu.org>
8996 * gnutls.c (emacs_gnutls_deinit): New function.
8997 Deallocate credentials structures as well as calling gnutls_deinit.
8998 (Fgnutls_deinit, Fgnutls_boot): Use it.
9000 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9001 (deactivate_process): Call emacs_gnutls_deinit.
9003 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9005 * image.c (x_create_x_image_and_pixmap):
9006 * w32.c (sys_rename, w32_delayed_load):
9007 * w32font.c (fill_in_logfont):
9008 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9010 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
9012 * w32fns.c (w32_default_color_map): New function,
9013 extracted from Fw32_default_color_map.
9014 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9016 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9018 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9020 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9022 * keyboard.c (test_undefined): New function (bug#9751).
9023 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
9025 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9027 * sysdep.c (init_sys_modes): Fix the check for the controlling
9028 terminal (Bug#6649).
9030 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9032 * dispextern.h (struct bidi_it): New member next_en_type.
9034 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9035 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9036 current character, check also for next_en_type being WEAK_EN.
9037 (bidi_resolve_weak): Don't enter the expensive loop if the current
9038 position is before next_en_pos. Record the bidi type of the first
9039 non-ET, non-BN character we find, in addition to its position.
9040 (bidi_level_of_next_char): Invalidate next_en_type when
9041 next_en_pos is over-stepped.
9043 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9045 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9046 * editfns.c: Rewrite current-time-zone so that it invokes
9047 the equivalent of (format-time-string "%Z") to get the time zone name.
9048 This fixes a bug when the time zone name contains characters that
9049 need converting from the system time locale to Emacs internal format.
9050 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9051 that patch fixed format-time-string to do the conversion, but
9052 I forgot to fix current-time-zone.
9053 (format_time_string): New function, containing most of
9054 what Fformat_time_string used to contain.
9055 (Fformat_time_string): Rewrite in terms of format_time_string.
9056 This doesn't change this function's behavior.
9057 (current-time-zone): Rewrite to use format_time_string.
9058 This fixes the bug reported by Michael Schierl in
9059 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9060 Jason Rumney's 2007-06-07 change worked around this bug, but
9062 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9064 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9066 * xdisp.c (start_display): If the character at POS is displayed
9067 via a display vector, reset IT->current.dpvec_index to zero.
9068 (try_window_reusing_current_matrix): If a line ends in a display
9069 vector or the next line starts in a display vector, continue
9070 redrawing the window even though the character position of
9071 start_row was reached.
9074 2011-10-18 Chong Yidong <cyd@gnu.org>
9076 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9077 with nobreak-char-display too.
9079 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9081 Fix part 3 of bug#9771.
9082 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9083 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9084 non-neutral characters if the current character is a paragraph
9085 separator (a.k.a. Newline). This avoids running the same
9086 expensive loop twice, once when we consume the preceding newline
9087 and the other time when the line actually needs to be displayed.
9088 Avoid the loop when we see neutrals on the base embedding level
9089 following a character whose directionality is the same as the
9090 paragraph's. This avoids running the expensive loop when a line
9091 ends in a long sequence of neutrals, like control characters.
9092 Add assertion against STRONG_AL type. Slightly rearrange code
9093 that determines the type of a neutral given the first non-neutral
9095 (bidi_level_of_next_char): Set next_en_pos to zero when
9096 invalidating its info.
9098 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9100 * xdisp.c (push_display_prop): Determine whether to record string
9101 or buffer position by IT->string, not by IT->method. Allow
9102 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9103 (move_it_vertically_backward): Don't look for character position
9104 immediately after the newline when in a continuation line.
9107 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9109 * window.c (coordinates_in_window): Rewrite and delabelize
9110 vertical border check. (Bug#5357) (Bug#9618)
9112 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9114 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9115 errors in XSetWindowBorder (bug#9310).
9117 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9119 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9120 avoid crash when xmalloc overrun checking is enabled.
9122 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9124 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9125 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9126 cursor motion with <left> and <right> arrow keys.
9128 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9129 some callers set that themselves.
9131 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9133 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9134 display string and the previous row comes from the same string and
9135 is empty. (Bug#9739) (Bug#9738)
9137 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9139 * doc.c (get_doc_string): Encode file name (bug#9735).
9141 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9143 * bidi.c (bidi_level_of_next_char):
9144 * xdisp.c (get_visually_first_element): Remove old incorrect
9145 comments regarding the Unicode Line Separator character.
9147 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9149 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9151 * alloc.c (Fgc_status): Do not access beyond zombies array
9152 boundary if nzombies > MAX_ZOMBIES.
9153 * alloc.c (dump_zombies): Add missing format specifier.
9155 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9157 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9158 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9160 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9161 Some packages use them to denote characters with modifiers.
9163 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9165 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9166 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9167 matching a pp-number. Rename parameter var to var1.
9169 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9171 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9173 2011-10-08 Glenn Morris <rgm@gnu.org>
9175 * callint.c (Fcall_interactively): Give a more explicit error for the
9176 'c' case with a non-character input. (Bug#8479)
9178 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9180 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9182 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9183 lines that are hscrolled on the left.
9185 * dispnew.c (buffer_posn_from_coords): Account for a possible
9186 presence of header-line. (Bug#4426)
9188 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9190 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9191 Don't advertise functionality which we discourage or doesn't work.
9193 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9195 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9196 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9197 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9198 this makes Emacs dump core during garbage collection on rare
9199 occasions. sizeof is obviously inferior to offsetof here, so
9200 stick with offsetof.
9201 (GC_POINTER_ALIGNMENT): New macro.
9202 (mark_memory): Omit 3rd (offset) arg; caller changed.
9203 Don't assume EMACS_INT alignment is the same as pointer alignment.
9205 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9207 * keyboard.c (read_key_sequence_remapped): New var.
9208 (read_key_sequence): Compute remapping in the right buffer.
9209 (command_loop_1): Use read_key_sequence's remapping directly.
9211 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9213 * dired.c (file_name_completion): Don't expand file name.
9214 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9215 before checking file name handler.
9217 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9218 they've been requested explicitly (bug#9591).
9220 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9222 * keymap.c (Fsingle_key_description): Use make_specified_string
9223 instead of build_string to build string from push_key_description.
9226 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9228 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9229 This fixes a Y2038 bug on 64-bit hosts.
9230 * buffer.c (reset_buffer):
9231 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9232 (Fclear_buffer_auto_save_failure):
9233 Use 0, not -1, to represent an unset failure time, since time_t
9234 might not be signed.
9236 Remove dependency on glibc malloc internals.
9237 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9238 Move back here from lisp.h, but with their new implementations.
9239 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9240 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9241 * charset.c (charset_table_init): New static var.
9242 (syms_of_charset): Use it instead of xmalloc. This removes a
9243 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9244 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9245 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9246 Move back to alloc.c.
9247 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9248 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9250 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9252 * nsterm.m (windowDidResize): Call x_set_window_size only when
9253 ns_in_resize is true. Otherwise set pixelwidth/height and
9254 call change_frame_size (Bug#9628).
9256 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9258 Port --enable-checking=all to Fedora 14 x86-64.
9259 * charset.c (syms_of_charset): Also account for glibc malloc's
9260 internal overhead when calculating the initial malloc maximum.
9262 Port --enable-checking=all to Fedora 14 x86.
9263 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9265 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9266 (overrun_check_realloc, overrun_check_free):
9267 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9268 That way, xmalloc returns a properly-aligned pointer even if
9269 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9270 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9271 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9272 into account when calculating the initial malloc maximum.
9273 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9274 Move here from alloc.c, so that charset.c can use it too.
9275 Properly align; the old code wasn't right for common 32-bit hosts
9276 when configured with --enable-checking=all.
9277 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9278 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9280 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9282 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9285 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9287 * xdisp.c (compute_display_string_end): If there's no display
9288 string at CHARPOS, return -1.
9290 * bidi.c (bidi_fetch_char): When compute_display_string_end
9291 returns a negative value, treat the character as a normal
9292 character not covered by a display string. (Bug#9624)
9294 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9296 * lread.c (Fread_from_string): Fix typo in docstring.
9298 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9300 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9301 newline, reseat the iterator instead of bidi-iterating there one
9302 character at a time. (Bug#9610)
9303 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9304 TO_CHARPOS if the bidi iterator is at base embedding level.
9306 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9308 * lread.c (readevalloop): Use correct code for NBSP.
9309 (read1): Likewise. (Bug#9608)
9311 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9313 * dbusbind.c (Fdbus_register_signal): When service is not
9314 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9316 2011-09-25 Glenn Morris <rgm@gnu.org>
9318 * buffer.c (truncate-lines): Doc fix.
9320 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9322 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9323 (Fset_window_next_buffers): Doc fix.
9325 2011-09-24 Glenn Morris <rgm@gnu.org>
9327 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9329 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9331 Fix minor problems found by static checking.
9332 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9333 * indent.c (Fvertical_motion): Fix == vs = typo.
9335 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9337 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9338 Default value is now t. Doc fix.
9340 * indent.c (Fvertical_motion): Compute and apply the overshoot
9341 logic when moving up, not only when moving down. Fix the
9342 confusing name and values of the it_overshoot_expected variable;
9343 logic changes accordingly. (Bug#9254) (Bug#9549)
9345 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9346 CHARPOS is covered by a display string which includes newlines.
9347 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9348 is covered by a display string with embedded newlines.
9350 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9352 * dbusbind.c (Fdbus_register_signal): Add match rule to
9353 Vdbus_registered_objects_table. (Bug#9581)
9354 (Fdbus_register_method, Vdbus_registered_objects_table):
9357 2011-09-24 Jim Meyering <meyering@redhat.com>
9359 do not ignore write error for any output size
9360 The previous change was incomplete.
9361 While it makes emacs --batch detect the vast majority of stdout
9362 write failures, errors were still ignored whenever the output size is
9363 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9364 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9365 && echo FAIL: ignored write error
9366 FAIL: ignored write error
9367 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9368 && echo FAIL: ignored write error
9369 FAIL: ignored write error
9370 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9372 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9374 * emacs.c (Fkill_emacs): In noninteractive mode exit
9375 non-successfully if a write error occurred on stdout. (Bug#9574)
9377 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9379 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9382 * dispextern.h (struct it): Update the comment documenting what
9385 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9387 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9388 a display string, extend search for cursor position to end of row.
9389 (find_row_edges): If the row ends in a newline from a display
9390 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9391 Handle the case of a display string with multiple newlines.
9392 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9393 non-empty line. Fixes confusing cursor motion with arrow keys at
9394 the beginning of a line that starts with whitespace.
9396 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9398 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9401 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9403 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9406 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9408 * xdisp.c (display_line): Record maximum and minimum buffer
9409 positions even if no glyphs were produced (e.g., by a zero-width
9410 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9411 buffer positions that will be removed from the glyph row because
9413 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9414 column is beyond frame width: don't subtract 1 "pixel" when
9415 computing width of the stretch.
9416 (reseat_at_next_visible_line_start): Undo the change made on
9417 2011-09-17 that saved paragraph information and restored it after
9418 the call to `reseat'. (Bug#9545)
9420 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9422 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9423 and turn window cursor on if cleared (Bug#9415).
9425 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9427 * search.c (boyer_moore): Take unibyte characters from pattern
9428 literally. (Bug#9458)
9430 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9432 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9434 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9436 Fix minor problem found by static checking.
9437 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9438 initialized, to pacify gcc -Wuninitialized.
9440 * fileio.c: Report proper errno when syscall falls.
9441 (Finsert_file_contents): Save and restore errno,
9442 so that report_file_error outputs the correct diagnostic.
9443 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9445 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9447 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9449 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9451 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9452 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9454 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9456 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9457 about the current paragraph and restore it after the call to reseat.
9459 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9460 (bidi_find_paragraph_start): Search back for paragraph beginning
9461 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9462 (bidi_move_to_visually_next): Only trigger paragraph-related
9463 computations when the last character is a newline or at EOB, not
9464 just any NEUTRAL_B. (Bug#9470)
9466 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9467 truncated lines if point is covered by a display string. (Bug#9524)
9469 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9471 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9472 (cons_to_x_long): New function.
9473 (lisp_data_to_selection_data): Use it. Correct the test for
9474 short-versus-long data; it was negated. Break out of vector
9475 loop, for efficiency, when a long datum is discovered.
9477 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9479 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9481 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9483 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
9484 GCC PR/17406) by declaring this function with external scope.
9486 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9488 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9489 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9491 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9493 * editfns.c (Fformat): Correctly handle text properties on "%%".
9495 2011-09-15 Eli Zaretskii <eliz@gnu.org>
9497 * xterm.c (x_draw_composite_glyph_string_foreground):
9498 * w32term.c (x_draw_composite_glyph_string_foreground):
9499 * term.c (encode_terminal_code):
9500 * composite.c (composition_update_it, get_composition_id):
9501 * xdisp.c (get_next_display_element)
9502 (fill_composite_glyph_string): Add comments about special meaning
9503 of TAB characters in a composition.
9505 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9507 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9508 This occurs when processing a multibyte format.
9509 Problem reported by Wolfgang Jenker.
9511 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9513 * xdisp.c (try_cursor_movement): Only check for exact match if
9514 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9516 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9518 Remove unused external symbols.
9519 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9520 * xdisp.c (calc_pixel_width_or_height): Now static.
9521 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9522 * indent.c (check_display_width):
9523 * w32term.c: Fix comment to match code.
9524 * xterm.c, xterm.h (x_catching_errors): Remove.
9526 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9528 * xselect.c: Use signed conversions more consistently (Bug#9498).
9529 (selection_data_to_lisp_data): Assume incoming selection data are
9530 signed integers, not unsigned. This is to be consistent with
9531 outgoing selection data, which was modified to use signed integers
9532 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9533 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9534 expects long, not unsigned long.
9536 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9538 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9539 computation of loop end. Reported by Johan Bockgård
9542 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9544 * frame.c (Fother_visible_frames_p): Function deleted.
9546 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9548 * indent.c (compute_motion): Process display vector front to back
9549 rather than the other way around. (Bug#2496)
9551 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9553 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9555 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9557 * minibuf.c (Fread_from_minibuffer): Doc fix.
9559 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9561 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9562 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9564 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9566 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9567 value for non-existent files.
9569 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9571 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9572 set its "size" to -1. This will set the modtime_size field of
9573 the corresponding buffer to -1, which is what
9574 verify-visited-file-modtime expects for files that do not exist.
9577 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9579 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9581 * lisp.h: ... from here. push_key_description is no longer
9582 defined in keyboard.c, so its declaration should not be in
9583 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9584 logically belongs with push_key_description.
9586 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9588 * buffer.h: Include <sys/types.h> instead of <time.h>.
9589 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9590 Problem reported by Herbert J. Skuhra.
9592 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9594 * xml.c (parse_region): Make the parsing work for
9595 non-comment-starting XML files again (bug#9144).
9597 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9599 * image.c (gif_load): Fix calculation of bottom and right corner.
9602 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9604 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9605 redisplay in small windows.
9607 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9609 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9611 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9613 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
9614 Operate on live windows only.
9616 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
9618 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
9620 2011-09-07 Eli Zaretskii <eliz@gnu.org>
9622 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
9623 only under bidi iteration.
9625 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
9627 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9629 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9631 isnan: Fix porting problem to Solaris 10 with bundled gcc.
9632 Without this fix, the command to link temacs failed due to an
9633 undefined symbol __builtin_isnan. This is because
9634 /usr/include/iso/math_c99.h #defines isnan(x) to
9635 __builtin_isnan(x), but the bundled gcc, which identifies itself
9636 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
9638 * floatfns.c (isnan): #undef, and then #define to a clone of
9640 (Fisnan): Always define, since it's always available now.
9641 (syms_of_floatfns): Always define isnan at the Lisp level.
9643 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9645 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
9647 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9649 * fileio.c: Fix bugs with large file offsets (Bug#9428).
9650 The previous code assumed that file offsets (off_t values) fit in
9651 EMACS_INT variables, which is not true on typical 32-bit hosts.
9652 The code messed up by falsely reporting buffer overflow in cases
9653 such as (insert-file-contents "big" nil 1 2) into an empty buffer
9654 when "big" contains more than 2**29 bytes, even though this
9655 inserts just one byte and does not overflow the buffer.
9656 (Finsert_file_contents): Store file offsets as off_t
9657 values, not as EMACS_INT values. Check for overflow when
9658 converting between EMACS_INT and off_t. When checking for
9659 buffer overflow or for overlap, take the offsets into account.
9660 Don't use EMACS_INT for small values where int suffices.
9661 When checking for overlap, fix a typo: ZV was used where
9662 ZV_BYTE was intended.
9663 (Fwrite_region): Don't assume off_t fits into 'long'.
9664 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
9666 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
9668 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
9670 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9672 sprintf-related integer and memory overflow issues (Bug#9412).
9674 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
9675 (esprintf, exprintf, evxprintf): New functions.
9676 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
9677 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
9678 (modify_event_symbol): Do not assume that the length of
9679 name_alist_or_stem is safe to alloca and fits in int.
9680 (Fexecute_extended_command): Likewise for function name and binding.
9681 (Frecursion_depth): Wrap around reliably on integer overflow.
9682 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
9683 since some callers pass EMACS_INT values.
9684 (Fsingle_key_description): Don't crash if symbol name contains more
9685 than MAX_ALLOCA bytes.
9686 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
9687 (get_minibuffer): Arg is now EMACS_INT, not int.
9688 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
9689 (esprintf, exprintf, evxprintf): New decls.
9690 * window.h (command_loop_level, minibuf_level): Reflect API changes.
9692 * dbusbind.c (signature_cat): New function.
9693 (xd_signature, Fdbus_register_signal):
9694 Do not overrun buffer; instead, report string overflow.
9696 * dispnew.c (add_window_display_history): Don't overrun buffer.
9697 Truncate instead; this is OK since it's just a log.
9699 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
9700 even if the time zone offset is outlandishly large.
9701 Don't mishandle offset == INT_MIN.
9703 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
9704 when creating daemon; the previous buffer-overflow check was incorrect.
9706 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
9707 which has the guts of the old verror function.
9709 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
9710 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
9712 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
9713 (font_unparse_xlfd): Don't blindly alloca long strings.
9714 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
9715 fits in int, when using sprintf. Use single snprintf to count
9716 length of string rather than counting it via multiple sprintfs;
9717 that's simpler and more reliable.
9718 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
9719 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
9720 sprintf, in case result does not fit in int.
9722 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
9723 (fontset_from_font): Print it.
9725 * frame.c (tty_frame_count): Now printmax_t, not int.
9726 (make_terminal_frame, set_term_frame_name): Print it.
9727 (x_report_frame_params): In X, window IDs are unsigned long,
9728 not signed long, so print them as unsigned.
9729 (validate_x_resource_name): Check for implausibly long names,
9730 and don't assume name length fits in 'int'.
9731 (x_get_resource_string): Don't blindly alloca invocation name;
9732 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
9735 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
9736 (xg_check_special_colors, xg_set_geometry):
9737 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
9739 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
9740 Use esprintf, not sprintf, in case result does not fit in int.
9742 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9743 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
9744 it as a large positive number.
9745 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
9746 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9748 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
9749 in case result does not fit in int.
9751 * print.c (float_to_string): Detect width overflow more reliably.
9752 (print_object): Make sprintf buffer a bit bigger, to avoid potential
9753 buffer overrun. Don't assume list length fits in 'int'. Treat
9754 print length of 0 as 0, not as infinity; to be consistent with other
9755 uses of print length in this function. Don't overflow print length
9756 index. Don't assume hash table size fits in 'long', or that
9757 vectorlike size fits in 'unsigned long'.
9759 * process.c (make_process): Use printmax_t, not int, to format
9760 process-name gensyms.
9762 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
9764 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
9765 to avoid potential buffer overrun.
9767 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
9768 if X resource line is longer than 512 bytes.
9770 * xfns.c (x_window): Make sprintf buffer a bit bigger
9771 to avoid potential buffer overrun.
9773 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
9775 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
9777 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9779 Integer overflow fixes for scrolling, etc.
9780 Without these, Emacs silently mishandles large integers sometimes.
9781 For example, "C-u 4294967297 M-x recenter" was treated as if
9782 it were "C-u 1 M-x recenter" on a typical 64-bit host.
9784 * xdisp.c (try_window_id): Check Emacs fixnum range before
9785 converting to 'int'.
9787 * window.c (window_scroll_line_based, Frecenter):
9788 Check that an Emacs fixnum is in range before assigning it to 'int'.
9789 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
9790 values converted from Emacs fixnums.
9791 (Frecenter): Don't wrap around a line count if it is out of 'int'
9792 range; instead, treat it as an extreme value.
9793 (Fset_window_configuration, compare_window_configurations):
9794 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
9796 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
9797 that can exceed INT_MAX. Check that EMACS_INT value is in range
9798 before assigning it to the (possibly-narrower) index.
9799 (match_limit): Don't assume that a fixnum can fit in 'int'.
9801 * print.c (print_object): Use ptrdiff_t, not int, for index that can
9804 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
9805 (Fvertical_motion): Don't wrap around LINES values that don't fit
9806 in 'int'. Instead, treat them as extreme values. This is good
9807 enough for windows, which can't have more than INT_MAX lines anyway.
9809 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9811 * Require libxml/parser.h to avoid compilation warning.
9813 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
9815 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
9816 since this reportedly can destroy thread storage.
9818 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
9820 * syntax.c (find_defun_start): Update all cache variables if
9821 exiting early (Bug#9401).
9823 2011-08-30 Eli Zaretskii <eliz@gnu.org>
9825 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
9827 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
9828 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
9829 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
9831 * term.c (tty_append_glyph): New function.
9832 (produce_stretch_glyph): Static function and its prototype deleted.
9834 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
9837 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
9839 * image.c (parse_image_spec): Check for nonnegative, not for positive,
9840 when checking :margin (Bug#9390).
9841 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
9842 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
9843 so that the name doesn't mislead. All uses changed.
9845 2011-08-28 Johan Bockgård <bojohan@gnu.org>
9847 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
9850 2011-08-27 Eli Zaretskii <eliz@gnu.org>
9852 * xdisp.c (move_it_to): Don't bail out early when reaching
9853 position beyond to_charpos, if we are scanning backwards.
9854 (move_it_vertically_backward): When DY == 0, make sure we get to
9855 the first character in the line after the newline.
9857 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
9859 * ccl.c: Improve and simplify overflow checking (Bug#9196).
9860 (ccl_driver): Do not generate an out-of-range pointer.
9861 (Fccl_execute_on_string): Remove unnecessary check for
9862 integer overflow, noted by Stefan Monnier in
9863 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
9864 Remove a FIXME that didn't need fixing.
9865 Simplify the newly-introduced buffer reallocation code.
9867 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
9869 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
9871 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
9873 Integer and memory overflow issues (Bug#9196).
9875 * doc.c (get_doc_string): Rework so that
9876 get_doc_string_buffer_size is the actual buffer size, rather than
9877 being 1 less than the actual buffer size; this makes xpalloc more
9880 * image.c (x_allocate_bitmap_record, cache_image):
9881 * xselect.c (Fx_register_dnd_atom):
9882 Simplify previous changes by using xpalloc.
9884 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
9885 since either will do and ptrdiff_t is convenient with xpalloc.
9887 * charset.c (charset_table_size)
9888 (struct charset_sort_data.priority): Now ptrdiff_t.
9889 (charset_compare): Don't overflow if priorities differ greatly.
9890 (Fsort_charsets): Don't assume list length fits in int.
9891 Check for size-calculation overflow when allocating sort data.
9892 (syms_of_charset): Allocate an initial charset table that is
9893 just under 64 KiB, to avoid problems with glibc malloc and mmap.
9895 * cmds.c (internal_self_insert): Check for size-calculation overflow.
9897 * composite.h (struct composition.glyph_len): Now int, not unsigned.
9898 The actual value is always <= INT_MAX, and leaving it unsigned made
9899 overflow checking harder.
9901 * dispextern.h (struct glyph_matrix.rows_allocated)
9902 (struct face_cache.size): Now ptrdiff_t, for convenience in use
9903 with xpalloc. The values are still always <= INT_MAX.
9905 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
9907 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
9908 (SAFE_NALLOCA): New macro.
9910 * region-cache.c (struct boundary.pos, find_cache_boundary)
9911 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
9912 (set_cache_region, invalidate_region_cache)
9913 (revalidate_region_cache, know_region_cache, region_cache_forward)
9914 (region_cache_backward, pp_cache):
9915 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
9916 so that ptrdiff_t * can be passed to xpalloc.
9917 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
9918 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
9919 (pp_cache): Don't assume cache_len fits in int.
9920 * region-cache.h: Adjust extern decls to match.
9922 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
9923 EMACS_INT, since either will do, for xpalloc.
9925 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
9926 (xnmalloc, xnrealloc, xpalloc): New functions.
9928 * bidi.c (bidi_shelve_header_size): New constant.
9929 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
9930 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
9932 * bidi.c (bidi_cache_shrink):
9933 * buffer.c (overlays_at, overlays_in, record_overlay_string)
9935 Don't update size of array until after memory allocation succeeds,
9936 because xmalloc/xrealloc may not return.
9937 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
9938 now that we have proper integer overflow checking.
9939 (record_overlay_string, overlay_strings): Catch overflows when
9940 calculating size of overlay_str_buf.
9942 * callproc.c (Fcall_process): Check for size overflow when
9943 calculating size of args2.
9944 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
9945 Normally we prefer signed values, but sticking with ptrdiff_t would
9946 require adding more-complicated checks.
9948 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
9949 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

9989 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
9991 * emacs.c (main): Do not reallocate argv, since there is a null at
9992 the end that can be overwritten, and this way there's no need to
9993 worry about size-calculation overflow.
9994 (sort_args): Check for size-calculation overflow.
9996 * eval.c (init_eval_once, grow_specpdl): Don't update size until

10002 Check for integer overflow.
10003 (x_set_alpha): Do not assume XINT fits in int.
10005 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10006 This is for the members text_lines, text_cols, total_lines, total_cols,
10007 where the system imposes an 'int' limit.

10016 Check for size-calculation overflow.
10017 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10018 do, as we prefer signed integers.

10025 * gtkutil.h: Change prototypes to match the above.
10027 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

10108 memory exhaustion (the usual treatment), rather than aborting.
10110 * xfns.c (x_encode_text, x_set_name_internal)
10111 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10112 sizes, since they can exceed INT_MAX in size. Check for size

10122 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10123 (X_LONG_MIN): New macros.
10124 Use them to make the following changes clearer.
10125 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10126 This change doesn't affect the value now, but it may help remind
10127 future maintainers not to raise the value too much later.
10128 (SELECTION_QUANTUM): Remove, replacing with ...
10129 (selection_quantum): ... new function, which avoids overflow.
10131 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10132 assumption that selection length fits in 'int'.

10149 Don't store size until memory allocation succeeds.
10150 (x_get_window_property): Plug memory leak on memory exhaustion.
10151 Don't double-block input; malloc is safe here. Don't assume 2**34
10152 - 4 fits in unsigned long. Add an xassert to check
10153 XGetWindowProperty overflow. Be more careful about overflow
10154 calculations, and distinguish size from memory overflow better.
10155 (receive_incremental_selection): When tracing, don't assume
10156 unsigned int is less than INT_MAX.
10157 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10160 in the range -65535 through -1 fit in an X unsigned short.
10161 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10162 result parameters unless successful. Rely on cons_to_unsigned
10163 to report problems with elements; the old code wasn't right anyway.
10164 (x_check_property_data): Check for int overflow; we cannot use
10165 a wider type due to X limits.

10198 * lisp.h (hash_lookup, hash_put):
10199 * minibuf.c (Ftest_completion):
10200 Use ptrdiff_t for hash table indexes, not int (which is too
10201 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10202 32-bit --with-wide-int hosts).
10204 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10205 Add a FIXME comment about memory leaks.

10213 with outlandish widths.
10214 * character.h (sanitize_tab_width): Rename from sanitize_width,
10215 now that we have two such functions. All uses changed.

10234 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10235 (x_send_scroll_bar_event): Likewise. Check that the size does not
10236 exceed limits imposed by XClientMessageEvent, as well as the usual
10237 ptrdiff_t and size_t limits.
10239 * keyboard.c: Overflow, signedness and related fixes.
10240 (make_lispy_movement): Use same integer type in forward decl
10241 that is used in the definition.
10242 (read_key_sequence, keyremap_step):
10243 Change bufsize argument back to int, undoing my 2011-03-30 change.
10244 We prefer signed types, and int is wide enough here.
10245 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10246 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10247 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10248 length, not size_t. Use ptrdiff_t for index, not int.
10249 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10250 possibility of integer overflow.

10278 Prefer int to unsigned where either will do.
10279 (tiff_handler): New function, combining the cores of the
10280 old tiff_error_handler and tiff_warning_handler.
10281 This function is rewritten to use vsnprintf and thereby avoid
10282 stack buffer overflows. It uses only the features of vsnprintf
10283 that are common to both POSIX and native Microsoft.
10284 (tiff_error_handler, tiff_warning_handler): Use it.
10285 (tiff_load, gif_load, imagemagick_load_image):
10286 Don't assume :index value fits in 'int'.
10287 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
10288 (imagemagick_load_image): Check that crop parameters fit into
10289 the integer types that MagickCropImage accepts. Don't assume
10290 Vimagemagick_render_type has a nonnegative value. Don't assume
10291 size_t fits in 'long'.
10292 (gs_load): Use printmax_t to print the widest integers possible.

10305 handle_single_display_spec, not just 1 or zero.
10306 (handle_single_display_spec): If the display spec is of the form
10307 `(space ...)', and specifies display in the text area, return 2
10309 (try_cursor_movement): Check for the need to scroll more
10310 accurately, and prefer exact match for point under bidi.
10311 Don't advance `row' beyond the last row of the window.

10328 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
10329 buffers, return left-to-right.
10330 (set_cursor_from_row): Consider candidate row a win if its glyph
10331 represents a newline and point is on that newline. Fixes cursor
10332 positioning on the newline at EOL of R2L text within L2R
10333 paragraph, and vice versa.
10334 (try_cursor_movement): Check continued rows, in addition to
10335 continuation rows. Fixes unwarranted scroll when point enters a
10336 continued line of R2L text within an L2R paragraph, or vice versa.
10337 (cursor_row_p): Consider the case of point being equal to
10338 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10339 from the end of a short line to the beginning of a continued line
10340 of R2L text within L2R paragraph.
10341 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

10364 * xdisp.c (redisplay_window): When computing centering_position,
10365 account for the height of the header line. (Bug#8874)
10367 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10368 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10369 candidate is selected by the mouse, and that candidate has a
10370 composed character under the mouse.
10372 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10373 coordinates reported by pos-visible-in-window-p for a composed
10374 character in column zero.
10376 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
10378 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
10380 2011-08-22 Eli Zaretskii <eliz@gnu.org>

10383 consider it a hit if to_charpos is anywhere in the range of the
10384 composed buffer positions.
10386 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10388 * image.c (gif_load): Don't assume that each subimage has the same
10389 dimensions as the base image. Handle disposal method that is
10390 "undefined" by the gif spec (Bug#9335).
10392 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
10394 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

10400 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10401 from an Org mode buffer to a Speedbar frame.
10403 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10404 a composition, take its buffer position from IT->cmp_it.charpos.
10405 Fixes cursor positioning at the beginning of a line that begins
10406 with a composed character.
10408 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10410 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10411 character bidirectional type, use STRONG_L instead. Fixes crashes
10412 in a buffer produced by `describe-categories'.
10414 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10415 members before the level stack, so they would be saved and
10416 restored when copying iterator state. Fixes incorrect reordering
10417 around TABs covered by display properties.
10419 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10421 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10426 (internal_condition_case_2, internal_condition_case_n):
10427 Remove unnecessary aborts (Bug#9081).
10429 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10431 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10432 has no `load' handler, try opening the file locally. (Bug#9311)
10434 2011-08-16 Ken Brown <kbrown@cornell.edu>
10436 * gmalloc.c: Expand comment.
10438 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10452 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
10454 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10455 in the static heap.
10456 [CYGWIN] (special_realloc): New function.
10457 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
10458 requests to realloc storage in the static heap.

10473 * chartab.c: Improve commentary for the uniprop_table API.
10475 * bidi.c (bidi_paragraph_init): Support zero value of
10476 bidi_ignore_explicit_marks_for_paragraph_level.

10487 after the pid of the process is set to -1 (Bug#8162).
10489 2011-08-14 Eli Zaretskii <eliz@gnu.org>
10491 * xdisp.c (move_it_in_display_line_to): Don't invoke
10492 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10493 ppos_it. Fixes vertical cursor motion when line beginning is
10494 covered by an image. (Bug#9296)
10496 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10498 * nsterm.h (ns_run_ascript): Declare.
10499 (NSAPP_DATA2_RUNASSCRIPT): Define.
10501 * nsfns.m (as_script, as_result, as_status): New static variables.
10502 (ns_run_ascript): New function.
10503 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10504 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10505 the event loop. Get status from as_status (Bug#7276).
10507 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10508 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10509 the event loop (Bug#7276).
10511 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10513 * gnutls.c (QCgnutls_bootprop_priority)

10515 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10516 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10517 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10518 (QCgnutls_bootprop_verify_hostname_error)
10519 (QCgnutls_bootprop_callbacks_verify): Rename from
10520 Qgnutls_bootprop_..., all uses changed.

10534 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10535 (Fnetwork_interface_list): Allocate in increments of bytes instead
10536 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10537 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10539 (struct ifflag_def): notrailers is smart on OSX.
10540 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10541 Get hardware address with getifaddrs if available.
10543 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10545 * xdisp.c (iterate_out_of_display_property): xassert that
10546 IT->position is set to within IT->object's boundaries. Break from
10547 the loop as soon as EOB is reached; avoids infloops in redisplay
10548 when IT->position is set up wrongly due to some bug.
10549 Set IT->current to match the bidi iterator unconditionally.
10550 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10551 entry. Force push_it to save on the stack the current
10552 buffer/string position, to be restored by pop_it. Fix flags in
10553 the iterator structure wrt the object coming from a display
10554 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10555 properties. (Bug#9284)
10557 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10559 * fontset.c (fontset_get_font_group): Add proper type checks.

10572 no-display-properties-and-no-overlays under bidi display.
10573 Set disp_pos in the bidi iterator to avoid searches for display
10574 properties and overlays.
10576 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10578 * editfns.c (Fset_time_zone_rule): Document relationship with the

10587 restore_point_unwind (Bug#5984).
10589 2011-08-07 Juri Linkov <juri@jurta.org>
10591 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10592 to show the arg `TIME' instead of `TIMEVAL'.
10594 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10596 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10597 display property strides EOL and includes a newline, as in
10598 longlines-mode. (Bug#9254)
10599 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10600 word-wrap under bidirectional display. (Bug#9224)
10602 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10603 is non-zero, even if the data buffer is NULL. Fixes a crash in
10604 vertical-motion with longlines-mode. (Bug#9254)
10606 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10608 * bidi.c <bidi_cache_total_alloc>: Now static.
10609 (bidi_initialize): Initialize bidi_cache_total_alloc.
10611 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10614 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10615 amount allocated this far in `bidi_cache_total_alloc'.
10616 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10617 non-zero, only free the data buffer without restoring the cache
10618 contents. All callers changed.
10620 * dispextern.h (bidi_unshelve_cache): Update prototype.
10622 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10623 (move_it_in_display_line, move_it_to)
10624 (move_it_vertically_backward, move_it_by_lines): Replace the call
10625 to xfree to an equivalent call to bidi_unshelve_cache.
10626 (move_it_in_display_line_to): Fix logic of returning
10627 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
10629 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10631 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
10632 came from a string character with a `cursor' property. (Bug#9229)
10634 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10636 * Makefile.in (LIB_PTHREAD): New variable.
10637 (LIBES): Add LIB_PTHREAD (Bug#9216).
10639 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
10640 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
10642 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
10644 * regex.c (re_iswctype): Remove some redundant boolean conversions.
10646 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10648 * xterm.c (x_find_topmost_parent): New function.
10649 (x_set_frame_alpha): Find topmost parent window with
10650 x_find_topmost_parent and set the property there also (bug#9181).
10651 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
10653 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
10655 * callproc.c (Fcall_process): Avoid vfork clobbering
10656 the local vars buffer, coding_systems, current_dir.

10664 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
10665 so that it is not optimized away.
10667 * xdisp.c (compute_display_string_pos): Remove unused local.
10669 2011-08-02 Eli Zaretskii <eliz@gnu.org>
10671 Fix slow cursor motion and scrolling in large buffers with
10672 selective display, like Org Mode buffers. (Bug#9218)
10674 * dispextern.h (struct bidi_it): New member disp_prop_p.
10676 * xdisp.c: Remove one-slot cache of display string positions.
10677 (compute_display_string_pos): Accept an additional argument

10679 for a display string or property. If found, set DISP_PROP_P
10682 * bidi.c (bidi_fetch_char): Accept an additional argument
10683 DISP_PROP_P, and pass it to compute_display_string_pos.
10684 Only handle text covered by a display string if DISP_PROP_P is returned
10685 non-zero. All callers of bidi_fetch_char changed.
10687 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
10689 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
10691 2010-12-03 Don March <don@ohspite.net>
10693 * keymap.c (Fdefine_key): Fix non-prefix key error message when
10694 last character M-[char] is translated to ESC [char] (bug#7541).
10696 2011-08-02 Kenichi Handa <handa@m17n.org>
10698 * lisp.h (uniprop_table): Extern it.
10700 * chartab.c (uniprop_table): Make it non-static.
10702 2011-08-01 Eli Zaretskii <eliz@gnu.org>
10704 * xdisp.c (forward_to_next_line_start): Accept additional argument
10705 BIDI_IT_PREV, and store into it the state of the bidi iterator had
10707 (reseat_at_next_visible_line_start): Use the bidi iterator state
10708 returned by forward_to_next_line_start to restore the state of
10709 it->bidi_it after backing up to previous newline. (Bug#9212)
10711 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
10713 * regex.c (re_comp): Protoize.
10714 (re_exec): Fix return type.
10715 (regexec): Fix type of `ret'. (Bug#9203)
10717 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10719 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
10720 This is needed if max-image-size is a floating-point number.
10722 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10724 * print.c (print_object): Print empty symbol as ##.

10730 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
10731 setting frame foreground color (Bug#9175).
10732 (x_set_background_color): Likewise.

10735 contents (Bug#9176).
10736 (EmacsTooltip -init): Remove bezels and add shadows to
10739 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
10740 or scroll bar (Bug#8470).
10742 * nsfont.m (nsfont_open): Remove assignment to voffset and

10746 * nsterm.h (nsfont_info): Remove voffset field.
10748 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10750 Implement strike-through and overline on NextStep (Bug#8863).
10752 * nsfont.m (nsfont_open): Use underline position provided by font,
10753 instead of hard-coded value of 2.
10754 (nsfont_draw): Call ns_draw_text_decoration instead.

10764 2011-07-28 Eli Zaretskii <eliz@gnu.org>
10766 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
10769 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10771 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
10772 Without this fix, if a signal arrives just after memory fills up,
10773 'malloc' might be invoked reentrantly.
10775 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
10776 In other words, assume that every image size is allowed, on non-X
10777 hosts. This assumption is probably wrong, but it lets Emacs compile.
10779 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10781 * regex.c (re_iswctype): Convert return values to boolean.
10783 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
10785 * xdisp.c (compute_display_string_pos): Don't use cached display
10786 string position if the buffer had its restriction changed.
10789 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10791 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10793 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10795 Integer signedness and overflow and related fixes. (Bug#9079)
10797 * bidi.c: Integer size and overflow fixes.
10798 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
10799 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
10800 (bidi_cache_find_level_change, bidi_cache_ensure_space)
10801 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
10802 (bidi_find_other_level_edge):
10803 Use ptrdiff_t instead of EMACS_INT where either will do.
10804 This works better on 32-bit hosts configured --with-wide-int.
10805 (bidi_cache_ensure_space): Check for size-calculation overflow.
10806 Use % rather than repeated addition, for better worst-case speed.
10807 Don't set bidi_cache_size until after xrealloc returns, because it
10809 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
10810 (bidi_cache_ensure_space): Also check that the bidi cache size
10811 does not exceed that of the largest Lisp string or buffer. See Eli
10812 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
10814 * alloc.c (__malloc_size_t): Remove.
10815 All uses replaced by size_t. See Andreas Schwab's note
10816 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
10818 * image.c: Improve checking for integer overflow.
10819 (check_image_size): Assume that f is nonnull, since
10820 it is always nonnull in practice. This is one less thing to
10821 worry about when checking for integer overflow later.
10822 (x_check_image_size): New function, which checks for integer
10823 overflow issues inside X.
10824 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
10825 This removes the need for a memory_full check.
10826 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
10827 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
10828 (xbm_read_bitmap_data): Change locals back to 'int', since
10829 their values must fit in 'int'.
10830 (xpm_load_image, png_load, tiff_load):
10831 Invoke x_create_x_image_and_pixmap earlier,
10832 to avoid much needless work if the image is too large.
10833 (tiff_load): Treat overly large images as if
10834 x_create_x_image_and_pixmap failed, not as malloc failures.
10835 (gs_load): Use x_check_image_size.
10837 * gtkutil.c: Omit integer casts.
10838 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
10839 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
10841 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
10843 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
10844 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
10845 would wrongly return t on a 64-bit host.
10847 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
10848 The plain *_OVERFLOW macros run afoul of GCC bug 49705
10849 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
10850 and therefore cause GCC to emit a bogus diagnostic in some cases.
10852 * image.c: Integer signedness and overflow and related fixes.
10853 This is not an exhaustive set of fixes, but it's time to
10854 record what I've got.
10855 (lookup_pixel_color, check_image_size): Remove redundant decls.
10856 (check_image_size): Don't assume that arbitrary EMACS_INT values
10857 fit in 'int', or that arbitrary 'double' values fit in 'int'.
10858 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
10859 (tiff_load, imagemagick_load_image):
10860 Check for overflow in size calculations.
10861 (x_create_x_image_and_pixmap): Remove unnecessary test for
10862 xmalloc returning NULL; that can't happen.
10863 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
10864 (xpm_color_bucket): Use better integer hashing function.
10865 (xpm_cache_color): Don't possibly over-allocate memory.
10866 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
10867 (gif_memory_source):
10868 Use ptrdiff_t, not int or size_t, to record sizes.
10869 (png_load): Don't assume values greater than 2**31 fit in 'int'.
10870 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
10871 either works, as we prefer signed integers.
10872 (tiff_read_from_memory, tiff_write_from_memory):
10873 Return tsize_t, not size_t, since that's what the TIFF API wants.
10874 (tiff_read_from_memory): Don't fail simply because the read would
10875 go past EOF; instead, return a short read.
10876 (tiff_load): Omit no-longer-needed casts.
10877 (Fimagemagick_types): Don't assume size fits into 'int'.
10879 Improve hashing quality when configured --with-wide-int.
10880 * fns.c (hash_string): New function, taken from sxhash_string.
10881 Do not discard information about ASCII character case; this
10882 discarding is no longer needed.
10883 (sxhash-string): Use it. Change sig to match it. Caller changed.
10884 * lisp.h: Declare it.
10885 * lread.c (hash_string): Remove, since we now use fns.c's version.
10886 The fns.c version returns a wider integer if --with-wide-int is
10887 specified, so this should help the quality of the hashing a bit.
10889 * emacs.c: Integer overflow minor fix.
10890 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
10891 Define only if GNU_LINUX.
10892 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
10894 * dispnew.c: Integer signedness and overflow fixes.
10895 Remove unnecessary forward decls, that were a maintenance hassle.
10896 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
10898 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
10899 (scrolling_window): Use ptrdiff_t, not int, for byte count.
10900 (prepare_desired_row, line_draw_cost):
10901 Use int, not unsigned, where either works.
10902 (save_current_matrix, restore_current_matrix):
10903 Use ptrdiff_t, not size_t, where either works.
10904 (init_display): Check for overflow more accurately, and without
10905 relying on undefined behavior.
10907 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
10908 Remove, replacing with the new symbols in lisp.h. All uses changed.
10909 * fileio.c (make_temp_name):
10910 * filelock.c (lock_file_1, lock_file):
10911 * xdisp.c (message_dolog):
10912 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
10913 Use pMd etc. instead.
10914 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
10915 replacing the pWIDE etc. symbols removed from editfns.c.
10917 * keyboard.h (num_input_events): Now uintmax_t.
10918 This is (very slightly) less likely to mess up due to wraparound.
10921 * buffer.c: Integer signedness fixes.
10922 (alloc_buffer_text, enlarge_buffer_text):
10923 Use ptrdiff_t rather than size_t when either will do, as we prefer
10926 * alloc.c: Integer signedness and overflow fixes.
10927 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
10928 (__malloc_size_t): Default to size_t, not to int.
10929 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
10930 (Fgarbage_collect, mark_object_loop_halt, mark_object):
10931 Prefer ptrdiff_t to size_t when either would do, as we prefer
10933 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
10934 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
10935 Now const. Initialize with values that are in range even if char
10937 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
10938 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
10939 These functions do the right thing with sizes > 2**32.
10940 (check_depth): Now ptrdiff_t, not int.
10941 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
10942 Adjust to new way of storing sizes. Check for size overflow bugs
10944 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
10945 slightly wrong anyway, as it missed one instance of
10946 XMALLOC_OVERRUN_CHECK_OVERHEAD.
10947 (refill_memory_reserve): Omit needless cast to size_t.
10948 (mark_object_loop_halt): Mark as externally visible.
10950 * xselect.c: Integer signedness and overflow fixes.
10951 (Fx_register_dnd_atom, x_handle_dnd_message):
10952 Use ptrdiff_t, not size_t, since we prefer signed.
10953 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
10954 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
10955 x_dnd_atoms_size and x_dnd_atoms_length.
10957 * doprnt.c: Prefer signed to unsigned when either works.
10959 * doprnt.c (doprnt):
10961 * xdisp.c (vmessage):
10962 Use ptrdiff_t, not size_t, when using or implementing doprnt,
10963 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
10964 prefer signed arithmetic to avoid comparison confusion.
10965 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
10966 but is a bit tricky.
10968 Assume freestanding C89 headers, string.h, stdlib.h.
10969 * data.c, doprnt.c, floatfns.c, print.c:
10970 Include float.h unconditionally.
10971 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10972 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10973 * regex.c: Likewise for stddef.h, string.h.
10974 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10975 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10976 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10977 (STDC_HEADERS): Remove obsolete defines.
10978 * sysdep.c: Include limits.h unconditionally.
10980 Assume support for memcmp, memcpy, memmove, memset.
10981 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10982 * regex.c (memcmp, memcpy):
10983 Remove; we assume C89 now.
10985 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
10986 (__malloc_safe_bcopy): Remove; no longer needed.
10988 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
10989 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
10990 well either way, and we prefer signed to unsigned.
10992 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
10994 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
10995 closes the connection while we're reading (bug#9182).
10997 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10999 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11000 are specified (Bug#9168).
11002 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11004 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11005 Found by GCC static checking and --with-wide-int on a 32-bit host.
11007 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11009 * xdisp.c (compute_display_string_pos): Fix logic of caching
11010 previous display string position. Initialize cached_prev_pos to
11011 -1. Fixes slow-down at the beginning of a buffer.
11013 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11015 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11016 for attrs[LFACE_FONTSET_INDEX].
11018 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11020 * xml.c (parse_region): Remove unused local
11021 that was recently introduced.
11023 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11025 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11026 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11028 * xdisp.c (move_it_in_display_line_to): Record the best matching
11029 position for TO_CHARPOS while scanning the line, and restore it on
11030 exit if none of the characters scanned was an exact match.
11031 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11032 when exact match is impossible due to invisible text, and the
11033 lines are truncated.
11035 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11037 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11040 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11042 Fix a significant slow-down of cursor motion with C-n, C-p,
11043 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11044 auto-repeat under bidi redisplay in fontified buffers.
11045 * xdisp.c (compute_stop_pos_backwards): New function.
11046 (next_element_from_buffer): Call compute_stop_pos_backwards to
11047 find a suitable prev_stop when we find ourselves before
11049 (reseat): Don't look for prev_stop, as that could mean a very long
11051 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11052 <cached_disp_overlay_modiff>: Cache for last found display string
11054 (compute_display_string_pos): Return the cached position if asked
11055 about the same buffer in the same area of character positions, and
11056 the buffer wasn't changed since the time the display string
11057 position was cached.
11059 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11061 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11062 is an integer, which is important for empty lines. (Bug#9149)
11064 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11066 * frame.c (Fmodify_frame_parameters): In tty case, update the
11067 default face if necessary (Bug#4238).
11069 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11071 * editfns.c (Fstring_to_char): No need to explain what a character
11072 is in the docstring (Bug#6576).
11074 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11076 * xml.c (parse_region): Make sure we always return a tree.
11078 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11080 * xml.c (parse_region): If a document contains only comments,
11083 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11085 * xml.c (make_dom): Return comments, too.
11087 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11090 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11091 and the surrounding thread.
11092 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11093 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11094 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11096 * s/openbsd.h (BROKEN_SIGIO): Define.
11097 * unexelf.c (unexec) [__OpenBSD__]:
11098 Don't update the .mdebug section of the Alpha COFF symbol table.
11100 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11102 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11105 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11107 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11108 This fixes some race conditions on the permissions of any newly
11111 * alloc.c (valid_pointer_p): Use pipe, not open.
11112 This fixes some permissions issues when debugging.
11114 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11115 If fchown fails to set both uid and gid, try to set just gid,
11116 as that is sometimes allowed. Adjust the file's mode to eliminate
11117 setuid or setgid bits that are inappropriate if fchown fails.
11119 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11121 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11122 to compare Lisp_Objects.
11123 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11124 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11125 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11127 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11129 * lread.c (read_integer): Unread even EOF character.
11130 (read1): Likewise. Properly record start position of symbol.
11132 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11133 symbol character follows.
11135 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11137 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11138 This works around a problem with the previous change to Fcopy_file.
11139 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11140 and without this change, GCC might complain about discarding
11141 fchown's return value.
11143 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11145 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11147 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11149 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11151 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11153 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11154 it's used from the C level.
11156 * process.c: Use the same condition for POLL_FOR_INPUT in both
11157 keyboard.c and process.c (bug#1858).
11159 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11161 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11162 (Fgnutls_boot): Use it.
11164 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11166 * doc.c (Fsubstitute_command_keys): Revert last change.
11168 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11170 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11171 quotes the next character, and doesn't affect other longer
11172 sequences (bug#8935).
11174 * lread.c (syms_of_lread): Clarify that is isn't only
11175 `eval-buffer' and `eval-defun' that's affected by
11176 `lexical-binding' (bug#8460).
11178 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11180 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11181 bidi redisplay when a line includes both an image and is truncated.
11183 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11185 Fix minor problems found by static checking.
11186 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11187 (elsz): Now a signed constant, not a size_t var. We prefer signed
11188 types to unsigned, to avoid integer comparison confusion. Without
11189 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11190 "cannot optimize loop, the loop counter may overflow", a symptom
11192 * indent.c (Fvertical_motion): Mark locals as initialized.
11193 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11195 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11197 * search.c (Fre_search_backward): Mention `case-fold-search' in
11198 all the re_search_* functions (bug#8138).
11200 * keyboard.c (Fopen_dribble_file): Document when the file is
11203 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11205 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11208 Support bidi reordering of display and overlay strings.
11209 * xdisp.c (compute_display_string_pos)
11210 (compute_display_string_end): Accept additional argument STRING.
11211 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11212 (reseat_to_string): Initialize bidi_it->string.s and
11213 bidi_it->string.schars.
11214 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11215 NULL (avoids a crash in bidi_paragraph_init).
11216 Initialize itb.string.lstring.
11217 (init_iterator): Call bidi_init_it only of a valid
11218 buffer position was specified. Initialize paragraph_embedding to
11220 (reseat_to_string): Initialize the bidi iterator.
11221 (display_string): If we need to ignore text properties of
11222 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11223 original value of -1 will not work with bidi.)
11224 (compute_display_string_pos): First arg is now struct
11225 `text_pos *'; all callers changed. Support display properties on
11227 (compute_display_string_end): Support display properties on Lisp
11229 (init_iterator, reseat_1, reseat_to_string): Initialize the
11230 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11231 when iterating on a string not from display properties).
11232 (compute_display_string_pos, compute_display_string_end):
11233 Fix calculation of the object to scan. Fixes an error when using
11235 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11236 base_level_stop; instead, set base_level_stop to BEGV.
11237 Fixes crashes in vertical-motion.
11238 (next_element_from_buffer): Improve commentary for when
11239 the iterator is before prev_stop.
11240 (init_iterator): Initialize bidi_p from the default value of
11241 bidi-display-reordering, not from buffer-local value. Use the
11242 buffer-local value only if initializing for buffer iteration.
11243 (handle_invisible_prop): Support invisible properties on strings
11244 that are being bidi-reordered.
11245 (set_iterator_to_next): Support bidi reordering of C strings and
11247 (next_element_from_string): Support bidi reordering of Lisp
11249 (handle_stop_backwards): Support Lisp strings as well.
11250 (display_string): Support display of R2L glyph rows.
11251 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11252 (init_iterator): Don't initialize it->bidi_p for strings
11254 (reseat_to_string): Initialize it->bidi_p for strings here.
11255 (next_element_from_string, next_element_from_c_string)
11256 (next_element_from_buffer): Add xassert's for correspondence
11257 between IT's object being iterated and it->bidi_it.string
11259 (face_before_or_after_it_pos): Support bidi iteration.
11260 (next_element_from_c_string): Handle the case of the first string
11261 character that is not the first one in the visual order.
11262 (get_visually_first_element): New function, refactored from common
11263 parts of next_element_from_buffer, next_element_from_string, and
11264 next_element_from_c_string.
11265 (tool_bar_lines_needed, redisplay_tool_bar)
11266 (display_menu_bar): Force left-to-right direction. Add a FIXME
11267 comment for making that be controlled by a user option.
11268 (push_it, pop_it): Save and restore the state of the
11269 bidi iterator. Save and restore the bidi_p flag.
11270 (pop_it): Iterate out of display property for string iteration as
11272 (iterate_out_of_display_property): Support iteration over strings.
11273 (handle_single_display_spec): Set up it->bidi_it for iteration
11274 over a display string, and call bidi_init_it.
11275 (handle_single_display_spec, next_overlay_string)
11276 (get_overlay_strings_1, push_display_prop): Set up the bidi

11715 * alloc.c (mark_buffer):
11716 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
11717 (clone_per_buffer_values): Don't assume that
11718 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
11719 This isn't true in general, and it's particularly not true
11720 if Emacs is configured with --with-wide-int.
11721 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
11722 New macros, used in the buffer.c change.

11730 (store_monospaced_changed): Add comment. Call dpyinfo_valid.
11731 (struct xsettings): Move font inside HAVE_XFT.
11732 (GSETTINGS_TOOL_BAR_STYLE, GSETTINGS_FONT_NAME): New defines.
11733 (GSETTINGS_MONO_FONT): Rename from SYSTEM_MONO_FONT.
11734 Move inside HAVE_XFT.

11743 (read_settings, apply_xft_settings): Add comment.
11744 (read_and_apply_settings): Add comment. Call map_tool_bar_style and

11756 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
11758 Random fixes. E.g., (random) never returned negative values.
11759 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
11760 subseconds part to the entropy, as that's a bit more random.
11761 Prefer signed to unsigned, since the signedness doesn't matter and
11762 in general we prefer signed. When given a limit, use a
11763 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
11764 latter isn't right if USE_2_TAGS_FOR_INTS.
11765 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
11766 not 0..VALMASK. Don't discard "excess" bits that random () returns.
11768 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11770 * textprop.c (text_property_stickiness):
11771 Obey Vtext_property_default_nonsticky.
11772 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.

11778 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
11779 This is more efficient than Ffile_directory_p and avoids a minor race.
11781 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
11783 * buffer.c (Foverlay_put): Say what the return value is
11786 * fileio.c (barf_or_query_if_file_exists): Check first if the file
11787 is a directory before asking whether to use the file name
11789 (barf_or_query_if_file_exists): Make the "File is a directory"
11790 error be more correct.
11792 * fns.c (Frequire): Remove the mention of the .gz files, since
11793 that's installation-specific, but keep the mention of
11794 `get-load-suffixes'.
11796 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
11798 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

11804 (syms_of_gnutls): Remove duplicate DEFSYM for
11805 Qgnutls_bootprop_verify_hostname_error, an error for
11806 Qgnutls_bootprop_verify_error (which is no longer used).
11808 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
11809 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
11810 Also (re)move comments that are misplaced or no longer relevant.
11812 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11814 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
11816 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
11818 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
11819 and background color parameters if they have been changed.

11873 (syms_of_keymap): Defsubr make-composed-keymap.
11874 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

11911 * eval.c (struct backtrace): Simplify and port the data structure.
11912 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
11913 signed bit field, as this assumption is not portable and it makes
11914 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
11915 "char debug_on_exit : 1" as this is not portable either; instead,
11916 use the portable "unsigned int debug_on_exit : 1". Remove unused
11917 member evalargs. Remove obsolete comments about cc bombing out.
11919 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12152 on undefined behavior with wrong number of arguments.
12153 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12154 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12155 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12156 since we're not interested in debugging glyphs with old libraries.
12157 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12158 GCC 4.6.0's static checking.
12160 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12162 Integer overflow and signedness fixes (Bug#8873).
12163 A few related buffer overrun fixes, too.
12165 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
12167 * dispextern.h (struct face.stipple):
12168 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)

12170 (x_create_bitmap_from_data, x_create_bitmap_from_file)
12171 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
12172 (x_create_bitmap_from_xpm_data):
12173 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
12174 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
12176 * xfaces.c (load_pixmap):
12177 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12178 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12179 (.bitmaps_last, struct x_output.icon_bitmap):
12180 Use ptrdiff_t, not int, for bitmap indexes.
12181 (x_allocate_bitmap_record): Check for size overflow.
12182 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12184 Use ptrdiff_t, not int, for overlay counts.
12185 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12186 * editfns.c (overlays_around, get_pos_property):
12187 * textprop.c (get_char_property_and_overlay):
12188 * xdisp.c (next_overlay_change, note_mouse_highlight):
12189 * xfaces.c (face_at_buffer_position):
12190 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12191 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12192 (Fnext_overlay_change, Fprevious_overlay_change)
12193 (mouse_face_overlay_overlaps, Foverlays_in):
12194 Use ptrdiff_t, not int, for sizes.
12195 (overlays_at, overlays_in): Check for size-calculation overflow.
12197 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12199 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12200 (x_session_initialize): Do not assume string length fits in int.
12202 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12203 This is unlikely, but can occur if DPI is outlandish.
12205 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12206 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12208 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12209 * xrdb.c (magic_file_p, search_magic_path):
12210 Omit last arg SUFFIX; it was always 0. All callers changed.
12211 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12213 * xfont.c (xfont_match): Avoid need for strlen.
12215 * xfns.c: Don't assume strlen fits in int.
12216 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12218 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12219 not unsigned long, as we prefer signed integers. All callers changed.
12220 Detect integer overflow in repeat count.
12221 (message_dolog): Don't assume print length fits in 39 bytes.
12222 (display_mode_element): Don't assume strlen fits in int.
12224 * termcap.c: Don't assume sizes fit in int and never overflow.
12225 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12226 (gobble_line): Check for size-calculation overflow.
12228 * minibuf.c (Fread_buffer):
12229 * lread.c (intern, intern_c_string):
12230 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12231 Don't assume string length fits in int.
12233 * keyboard.c (parse_tool_bar_item):
12234 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12236 * font.c: Don't assume string length fits in int.
12237 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12238 Use ptrdiff_t, not int.
12239 (font_intern_prop): Don't assume string length fits in int.
12240 Don't assume integer property fits in fixnum.
12241 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12243 * filelock.c: Fix some buffer overrun and integer overflow issues.
12244 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12245 Reformulate so as not to need the command string.
12246 Invoke gzip -cd rather than gunzip, as it's more portable.
12247 (lock_info_type, lock_file_1, lock_file):
12248 Don't assume pid_t and time_t fit in unsigned long.
12249 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12250 (current_lock_owner): Prefer signed type for sizes.
12251 Use memcpy, not strncpy, where memcpy is what is really wanted.
12252 Don't assume (via atoi) that time_t and pid_t fit in int.
12253 Check for time_t and/or pid_t out of range, e.g., via a network share.
12254 Don't alloca where an auto var works fine.
12256 * fileio.c: Fix some integer overflow issues.
12257 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12258 Don't assume string length fits in int.
12259 (directory_file_name): Don't assume string length fits in long.
12260 (make_temp_name): Don't assume pid fits in int, or that its print
12261 length is less than 20.
12263 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12265 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12267 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12269 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12270 We prefer signed integers, even for size calculations.
12272 * emacs.c: Don't assume string length fits in 'int'.
12273 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12274 (main): Don't invoke strlen when not needed.
12276 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12277 (XD_DEBUG_MESSAGE): Don't waste a byte.
12279 * callproc.c (getenv_internal_1, getenv_internal)
12280 (Fgetenv_internal):
12281 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12283 * lread.c (invalid_syntax): Omit length argument.
12284 All uses changed. This doesn't fix a bug, but it simplifies the
12285 code away from its former Hollerith-constant appearance, and it's
12286 one less 'int' to worry about when looking at integer-overflow issues.
12287 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12289 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12290 This didn't break anything, but it didn't help either.
12291 It's confusing to put a bogus integer in a place where the actual
12292 value does not matter.
12293 (LIST_END_P): Remove unused macro and its bogus comment.
12294 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12296 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12297 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12299 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12300 We prefer signed types, and the value cannot exceed the EMACS_INT
12301 range anyway (because otherwise the length would not be representable).
12302 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12303 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12304 This avoids a GCC warning when WIDE_EMACS_INT.
12306 * indent.c (sane_tab_width): New function.
12307 (current_column, scan_for_column, Findent_to, position_indentation)
12308 (compute_motion): Use it. This is just for clarity.
12309 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12311 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12313 * lisp.h (lint_assume): New macro.
12314 * composite.c (composition_gstring_put_cache):
12315 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12317 * editfns.c, insdel.c:
12318 Omit unnecessary forward decls, to simplify future changes.
12320 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12322 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12324 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12325 Use much-faster test for byte-length change.
12326 Don't assume string byte-length fits in 'int'.
12327 Check that character arg fits in 'int'.
12328 (mapcar1): Declare byte as byte, for clarity.
12330 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12332 * fns.c (concat): Catch string overflow earlier.
12333 Do not rely on integer wraparound.
12335 * dispextern.h (struct it.overlay_strings_charpos)
12336 (struct it.selective): Now EMACS_INT, not int.
12337 * xdisp.c (forward_to_next_line_start)
12338 (back_to_previous_visible_line_start)
12339 (reseat_at_next_visible_line_start, next_element_from_buffer):
12340 Don't arbitrarily truncate the value of 'selective' to int.
12342 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12344 * composite.c: Don't truncate sizes to 'int'.
12345 (composition_gstring_p, composition_reseat_it)
12346 (composition_adjust_point): Use EMACS_INT, not int.
12347 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12348 not EMACS_UINT, for indexes.
12350 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12352 * buffer.c: Include <verify.h>.
12353 (struct sortvec.priority, struct sortstr.priority):
12354 Now EMACS_INT, not int.
12355 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12356 (struct sortstr.size, record_overlay_string)
12357 (struct sortstrlist.size, struct sortlist.used):
12358 Don't truncate size to int.
12359 (record_overlay_string): Check for size-calculation overflow.
12360 (init_buffer_once): Check at compile-time, not run-time.
12362 2011-06-22 Jim Meyering <meyering@redhat.com>
12364 Don't leak an XBM-image-sized buffer
12365 * image.c (xbm_load): Free the image buffer after using it.
12367 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12370 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12371 that Sun C diagnosed.
12372 * fns.c (secure_hash): Fix pointer signedness issue.
12373 * intervals.c (static_offset_intervals): New function.
12374 (offset_intervals): Use it.
12376 2011-06-21 Leo Liu <sdl.web@gmail.com>
12379 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12382 * fns.c (secure_hash): Rename from crypto_hash_function and change
12383 the first arg to accept symbols.
12384 (Fsecure_hash): New primitive.
12385 (syms_of_fns): New symbols.
12387 2011-06-20 Deniz Dogan <deniz@dogan.se>
12389 * process.c (Fset_process_buffer): Clarify return value in
12392 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12394 * dispnew.c (add_window_display_history): Use BVAR.
12396 * xdisp.c (debug_method_add): Use BVAR.
12397 (check_window_end, dump_glyph_matrix, dump_glyph)
12398 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12400 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12403 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12404 check till after the cache is created in init_frame_faces.
12406 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12408 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12410 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12412 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12413 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12414 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12416 Improve buffer-overflow checking (Bug#8873).
12417 * fileio.c (Finsert_file_contents):
12418 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12419 Remove the old (too-loose) buffer overflow checks.
12420 They weren't needed, since make_gap checks for buffer overflow.
12421 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12422 The old code merely checked for Emacs fixnum overflow, and relied
12423 on undefined (wraparound) behavior. The new code avoids undefined
12424 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12426 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12427 Tune. Don't use wider integers than needed. Don't use alloca.
12428 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12430 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12432 * insdel.c, lisp.h (buffer_overflow): New function.
12433 (insert_from_buffer_1, replace_range, replace_range_2):
12434 * insdel.c (make_gap_larger):
12435 * editfns.c (Finsert_char):
12436 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12438 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12440 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12442 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12444 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12445 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12447 * fileio.c: Don't assume EMACS_INT fits in off_t.
12448 (emacs_lseek): New static function.
12449 (Finsert_file_contents, Fwrite_region): Use it.
12450 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12452 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12454 * fns.c: Don't overflow int when computing a list length.
12455 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12456 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12457 truncation on 64-bit hosts. Check for QUIT every
12458 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12459 faster and is responsive enough.
12460 (Flength): Report an error instead of overflowing an integer.
12461 (Fsafe_length): Return a float if the value is not representable
12462 as a fixnum. This shouldn't happen except in contrived situations.
12463 (Fnthcdr, Fsort): Don't assume list length fits in int.
12464 (Fcopy_sequence): Don't assume vector length fits in int.
12466 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12467 (header_size, word_size): New constants.
12468 (allocate_vectorlike): Don't check size overflow here.
12469 (allocate_vector): Check it here instead, since this is the only
12470 caller of allocate_vectorlike that could cause overflow.
12471 Check that the new vector's length is representable as a fixnum.
12473 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12474 The previous code was bogus. For example, next_almost_prime (32)
12475 returned 39, which is undesirable as it is a multiple of 3; and
12476 next_almost_prime (24) returned 25, which is a multiple of 5 so
12477 why was the code bothering to check for multiples of 7?
12479 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12481 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12483 Variadic C functions now count arguments with ptrdiff_t.
12484 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12485 Back then I didn't know that the Emacs coding style prefers signed int.
12486 Also, in the meantime I found a few more instances where arguments
12487 were being counted with int, which may truncate counts on 64-bit
12488 machines, or EMACS_INT, which may be unnecessarily wide.
12489 * lisp.h (struct Lisp_Subr.function.aMANY)
12490 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12491 Arg counts are now ptrdiff_t, not size_t.
12492 All variadic functions and their callers changed accordingly.
12493 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12494 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12495 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12496 * callint.c (Fcall_interactively): Check arg count for overflow,
12497 to avoid potential buffer overrun. Use signed char, not 'int',
12498 for 'varies' array, so that we needn't bother to check its size
12499 calculation for overflow.
12500 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12501 * eval.c (apply_lambda):
12502 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12503 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12504 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12506 * callint.c (Fcall_interactively): Don't use index var as event count.
12508 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12509 * mem-limits.h (SIZE): Remove; no longer used.
12511 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12513 Remove unnecessary casts.
12514 * xterm.c (x_term_init):
12515 * xfns.c (x_set_border_pixel):
12516 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12517 These aren't needed now that we assume ANSI C.
12519 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12520 It's more likely to cause problems (due to unsigned overflow)
12523 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12525 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12527 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12529 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12531 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12533 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12535 GLYPH_CODE_FACE returns EMACS_INT, not int.
12536 * dispextern.h (merge_faces):
12537 * xfaces.c (merge_faces):
12538 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12539 Don't assume EMACS_INT fits in int.
12541 * character.h (CHAR_VALID_P): Remove unused parameter.
12542 * fontset.c, lisp.h, xdisp.c: All uses changed.
12544 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12546 * fns.c (concat): Minor tuning based on overflow analysis.
12547 This doesn't fix any bugs. Use int to hold character, instead
12548 of constantly refetching from Emacs object. Use XFASTINT, not
12549 XINT, for value known to be a character. Don't bother comparing
12550 a single byte to 0400, as it's always less.
12552 * floatfns.c (Fexpt):
12553 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12555 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12558 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12560 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12561 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12562 incorrectly succeed when S was a string, because 4294967386 was
12563 truncated before it was used.
12565 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12566 Otherwise, an out-of-range integer could cause undefined behavior
12569 * composite.c: Use int, not EMACS_INT, for characters.
12570 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12571 EMACS_INT, for values that are known to be in character range.
12572 This doesn't fix any bugs but is the usual style inside Emacs and
12573 may generate better code on 32-bit machines.
12575 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12576 This is for reasons similar to the recent CHAR_STRING fix.
12577 * charset.c (Fencode_char): Check that character arg is actually
12578 a character. Pass an int to ENCODE_CHAR.
12579 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12580 wider than 'int', as a compile-time check to prevent future regressions
12583 * character.c (char_string): Remove unnecessary casts.
12585 Make sure a 64-bit char is never passed to CHAR_STRING.
12586 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12587 by silently ignoring the top 32 bits, allowing some values
12588 that were far too large to be valid characters.
12589 * character.h: Include <verify.h>.
12590 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12591 arguments are no wider than unsigned, as a compile-time check
12592 to prevent future regressions in this area.

12598 Adjust to CHAR_STRING's new requirement.
12599 * editfns.c (Finsert_char, Fsubst_char_in_region):
12600 * fns.c (concat): Check that character args are actually
12601 characters. Without this test, these functions did the wrong
12602 thing with wildly out-of-range values on 64-bit hosts.
12604 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12605 These casts should not be needed on 32-bit hosts, either.
12606 * keyboard.c (read_char):
12607 * lread.c (Fload): Remove casts to unsigned.
12609 * lisp.h (UNSIGNED_CMP): New macro.

12617 * keyboard.c (read_char): Use UNSIGNED_CMP.
12619 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
12620 not to EMACS_INT, to avoid GCC warning.
12622 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
12624 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
12625 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
12626 isn't needed on 32-bit machines.
12628 * buffer.c (Fgenerate_new_buffer_name):
12629 Use EMACS_INT for count, not int.
12630 (advance_to_char_boundary): Return EMACS_INT, not int.

12649 (total_free_floats, total_floats, total_free_intervals)
12650 (total_intervals, total_strings, total_free_strings):
12651 Now EMACS_INT, not int. All uses changed.
12652 (Fgarbage_collect): Compute overall total using a double, so that
12653 integer overflow is less likely to be a problem. Check for overflow
12654 when converting back to an integer.
12655 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
12656 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
12657 These were 'int' variables that could overflow on 64-bit hosts;
12658 they were never used, so remove them instead of repairing them.
12659 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
12660 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
12661 Previously, this ceilinged at INT_MAX, but that doesn't work on
12663 (allocate_pseudovector): Don't use EMACS_INT when int would do.
12665 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
12666 (allocate_vectorlike): Check for ptrdiff_t overflow.
12667 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
12668 when a (possibly-narrower) signed value would do just as well.
12669 We prefer using signed arithmetic, to avoid comparison confusion.
12671 * alloc.c: Catch some string size overflows that we were missing.
12672 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
12673 for convenience in STRING_BYTES_MAX.
12674 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
12675 The definition here is exact; the one in lisp.h was approximate.
12676 (allocate_string_data): Check for string overflow. This catches
12677 some instances we weren't catching before. Also, it catches
12678 size_t overflow on (unusual) hosts where SIZE_MAX <= min
12679 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
12680 and ptrdiff_t and EMACS_INT are both 64 bits.
12682 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
12683 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
12684 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
12686 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
12688 * alloc.c (Fmake_string): Check for out-of-range init.

13261 instead of using explicit *_CHAR codes.
13262 (bidi_resolve_explicit, bidi_resolve_weak):

13271 (bidi_level_of_next_char): Don't try to lookup the cache for the
13272 next/previous character if nothing is cached there yet, or if we
13273 were just reseat()'ed to a new position.
13275 * xdisp.c (set_cursor_from_row): Set start and stop points
13276 according to the row's direction when priming the loop that looks
13277 for the glyph on which to display cursor.

13279 (display_prop_intangible_p): Reimplement to call
13280 handle_display_spec instead of single_display_spec_intangible_p.
13281 Accept 3 additional arguments needed by handle_display_spec.
13282 This fixes incorrect cursor motion across display property with complex
13283 values: lists, `(when COND...)' forms, etc.

13291 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13292 value of a `display' property is a "replacing spec".
13293 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13294 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13295 the display property, but just return a value indicating whether
13296 the display property will replace the characters it covers.
13297 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13298 frame_window_p members of struct bidi_it.
13299 (compute_display_string_pos, compute_display_string_end):

13324 * gnutls.c: Use Emacs's memory allocators.
13325 Without this change, the gnutls library would invoke malloc etc.
13326 directly, which causes problems on non-SYNC_INPUT hosts, and which
13327 runs afoul of improving memory_full behavior. (Bug#8761)
13328 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13329 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13330 xfree instead of the default malloc, realloc, free.
13331 (Fgnutls_boot): No need to check for memory allocation failure,
13332 since xmalloc does that for us.
13334 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

13354 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
13355 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13356 * alloc.c (allocate_vectorlike):
13357 Check for overflow in vector size calculations.
13358 * ccl.c (ccl_driver):
13359 Check for overflow when converting EMACS_INT to int.

13361 need to be updated by these changes.
13362 * fns.c (make_hash_table, maybe_resize_hash_table):
13363 Check for integer overflow with large hash tables.
13364 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13365 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13366 (SXHASH_REDUCE): New macro.
13367 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13368 Use it instead of discarding useful hash info with large hash values.
13369 (sxhash_float): New function.
13370 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13371 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13372 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13373 Rewrite to use FIXNUM_BITS, as this simplifies things.
13374 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13375 Adjust signatures to match updated version of code.
13376 (consing_since_gc): Now EMACS_INT, since a single hash table can
13377 use more than INT_MAX bytes.

13426 Make it possible to run ./temacs.
13428 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13429 syms_of_callproc does the same thing. Remove test for

13458 * image.c: Various fixes to ImageMagick code comments.
13459 (Fimagemagick_types): Doc fix.
13461 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13463 Minor fixes prompted by GCC 4.6.0 warnings.
13465 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13467 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13468 (x_clipboard_manager_save_all): Move extern decl to ...
13469 * xterm.h: ... here, so that it can be checked for consistency.
13471 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13473 * xselect.c (x_clipboard_manager_save_frame)
13474 (x_clipboard_manager_save_all): New functions.
13475 (Fx_clipboard_manager_save): Lisp function deleted.
13477 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13478 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13480 * xterm.h: Update prototype.
13482 2011-05-28 William Xu <william.xwl@gmail.com>
13484 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13485 exiting (Bug#8239).
13487 2011-05-28 Jim Meyering <meyering@redhat.com>
13489 Avoid a sign-extension bug in crypto_hash_function.
13490 * fns.c (to_uchar): Define.
13491 (crypto_hash_function): Use it to convert some newly-signed
13492 variables to unsigned, to avoid sign-extension bugs. For example,
13493 without this change, (md5 "truc") would evaluate to
13494 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13495 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13496 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13498 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13500 Integer overflow fixes.
13502 * dbusbind.c: Serial number integer overflow fixes.
13503 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13504 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13505 to hold a serial number that is too large for a fixnum.
13506 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13507 Check for serial numbers out of range. Decode any serial number
13508 that was so large that it became a float. (Bug#8722)
13510 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13511 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13512 Use XFASTINT rather than XUINT when numbers are nonnegative.
13513 (xd_append_arg, Fdbus_method_return_internal):
13514 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13515 arguments, check that Lisp number is nonnegative, rather than
13516 silently wrapping negative numbers around. (Bug#8722)
13517 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13520 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13522 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13524 ccl: Add integer overflow checks.
13525 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13526 (IN_INT_RANGE): New macros.
13527 (ccl_driver): Use them to check for integer overflow when
13528 decoding a CCL program. Many of the new checks are whether XINT (x)
13529 fits in int; it doesn't always, on 64-bit hosts. The new version
13530 doesn't catch all possible integer overflows, but it's an
13531 improvement. (Bug#8719)
13533 * alloc.c (make_event_array): Use XINT, not XUINT.
13534 There's no need for unsigned here.
13536 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13537 This follows up to the 2011-05-06 change that substituted uintptr_t
13538 for EMACS_INT. This case wasn't caught back then.
13540 Rework Fformat to avoid integer overflow issues.
13541 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13542 now (part of C89). Include <verify.h>.
13543 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13544 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13545 (Fformat): Avoid the prepass trying to compute sizes; it was only
13546 approximate and thus did not catch overflow reliably. Instead, walk
13547 through the format just once, formatting and computing sizes as we go,
13548 checking for integer overflow at every step, and allocating a larger
13549 buffer as needed. Keep track separately whether the format is
13550 multibyte. Keep only the most-recently calculated precision, rather
13551 than them all. Record whether each argument has been converted to
13552 string. Use EMACS_INT, not int, for byte and char and arg counts.
13553 Support field widths and precisions larger than INT_MAX. Avoid
13554 sprintf's undefined behavior with conversion specifications such as %#d
13555 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13556 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13557 formatting out-of-range floating point numbers with int
13558 formats. (Bug#8668)
13560 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13562 * data.c: Avoid integer truncation in expressions involving floats.
13563 * data.c: Include <intprops.h>.
13564 (arith_driver): When there's an integer overflow in an expression
13565 involving floating point, convert the integers to floating point
13566 so that the resulting value does not suffer from catastrophic
13567 integer truncation. For example, on a 64-bit host (* 4
13568 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13569 Do not rely on undefined behavior after integer overflow.
13571 merge count_size_as_multibyte, parse_str_to_multibyte
13572 * character.c, character.h (count_size_as_multibyte):
13573 Rename from parse_str_to_multibyte; all uses changed.
13574 Check for integer overflow.
13575 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13576 since it's now a duplicate of the other. This is more of
13577 a character than a buffer op, so better that it's in character.c.
13578 * fns.c, print.c: Adjust to above changes.
13580 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13582 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13584 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13586 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13587 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13588 (x_clipboard_manager_save): Now static.
13589 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13591 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13592 (crypto_hash_function): Now static.
13593 Fix pointer signedness problems. Avoid unnecessary initializations.
13595 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13597 * termhooks.h (Vselection_alist): Make it terminal-local.
13599 * terminal.c (create_terminal): Initialize it.
13601 * xselect.c: Support for clipboard managers.
13602 (Vselection_alist): Move to termhooks.h as terminal-local var.
13603 (LOCAL_SELECTION): New macro.
13604 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13605 (symbol_to_x_atom): Remove gratuitous arg.
13606 (x_handle_selection_request, lisp_data_to_selection_data)
13607 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13608 (x_own_selection, x_get_local_selection, x_convert_selection):
13609 New arg, specifying work frame. Use terminal-local Vselection_alist.
13610 (some_frame_on_display): Delete unused function.
13611 (Fx_own_selection_internal, Fx_get_selection_internal)
13612 (Fx_disown_selection_internal, Fx_selection_owner_p)
13613 (Fx_selection_exists_p): New optional frame arg.
13614 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13615 (x_handle_selection_clear): Don't treat other terminals with the
13616 same keyboard specially. Use the terminal-local Vselection_alist.
13617 (x_clear_frame_selections): Use Frun_hook_with_args.
13619 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13621 * xterm.h: Add support for those atoms.
13623 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13625 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13626 (converted_selections, conversion_fail_tag): New global variables.
13627 (x_selection_request_lisp_error): Free the above.
13628 (x_get_local_selection): Remove unnecessary code.
13629 (x_reply_selection_request): Args changed; handle arbitrary array
13630 of converted selections stored in converted_selections.
13631 Separate the XChangeProperty and SelectionNotify steps.
13632 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
13633 (x_convert_selection): New function.
13634 (x_handle_selection_event): Simplify.
13635 (x_get_foreign_selection): Don't ignore incoming requests while
13636 waiting for an answer; this will fail when we implement
13637 SAVE_TARGETS, and seems unnecessary anyway.
13638 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
13639 (Vx_sent_selection_functions): Doc fix.
13641 2011-05-26 Leo Liu <sdl.web@gmail.com>
13643 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
13645 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13647 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
13649 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
13650 for fringe update if it has periodic bitmap.
13651 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
13652 and fringe_bitmap_periodic_p.
13654 * fringe.c (get_fringe_bitmap_data): New function.
13655 (draw_fringe_bitmap_1, update_window_fringes): Use it.
13656 (update_window_fringes): Record periodicity of fringe bitmap in glyph
13657 row. Mark glyph row for fringe update if periodicity changed.
13659 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
13660 for fringe update unless it has periodic bitmap.
13662 2011-05-25 Kenichi Handa <handa@m17n.org>
13664 * xdisp.c (get_next_display_element): Set correct it->face_id for
13665 a static composition.
13667 2011-05-24 Leo Liu <sdl.web@gmail.com>
13670 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
13672 * fns.c (crypto_hash_function, Fsha1): New function.
13673 (Fmd5): Use crypto_hash_function.
13674 (syms_of_fns): Add Ssha1.
13676 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13678 * gnutls.c: Remove unused macros.
13679 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
13680 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
13681 Remove macros that are defined and never used.
13682 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
13684 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13686 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
13687 (Fx_get_selection_internal): Minor cleanup.
13688 (Fx_own_selection_internal): Rename arguments for consistency with
13691 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13693 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
13695 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13697 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
13699 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13701 * dispnew.c (scrolling_window): Don't exclude the case that the
13702 last enabled row in the desired matrix touches the bottom boundary.
13704 2011-05-21 Glenn Morris <rgm@gnu.org>
13706 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
13707 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
13708 and add some more files.
13710 2011-05-20 Eli Zaretskii <eliz@gnu.org>
13712 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
13713 report_file_error introduced by the change from 2011-05-07.
13715 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
13717 * systime.h (Time): Define only if emacs is defined.
13718 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
13719 where the include path doesn't have X11/X.h by default. See
13720 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
13722 2011-05-20 Kenichi Handa <handa@m17n.org>
13724 * composite.c (find_automatic_composition): Fix previous change.
13726 2011-05-20 Glenn Morris <rgm@gnu.org>
13728 * lisp.mk: New file, split from Makefile.in.
13729 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
13730 (shortlisp): Remove.
13731 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
13733 2011-05-19 Glenn Morris <rgm@gnu.org>
13735 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
13736 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
13737 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
13738 (lisp): Set the order to that of loadup.el.
13739 (shortlisp): Make it a copy of $lisp.
13740 (SOME_MACHINE_LISP): Remove.
13741 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
13742 Use just $shortlisp, not $SOME_MACHINE_LISP too.
13744 2011-05-18 Kenichi Handa <handa@m17n.org>
13746 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
13747 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
13748 (find_automatic_composition): Mostly rewrite for efficiency.
13750 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
13752 * makefile.w32-in: Update dependencies.
13754 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
13756 * menu.c: Include limits.h (fixes the MS-Windows build broken by
13757 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
13759 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
13761 Fix some integer overflow issues, such as string length overflow.
13763 * insdel.c (count_size_as_multibyte): Check for string overflow.
13765 * character.c (lisp_string_width): Check for string overflow.
13766 Use EMACS_INT, not int, for string indexes and lengths; in
13767 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
13768 the resulting string length overflows an EMACS_INT; instead,
13769 report a string overflow if no precision given. When checking for
13770 precision exhaustion, use a check that cannot possibly have
13771 integer overflow. (Bug#8675)
13772 * character.h (lisp_string_width): Adjust to new signature.
13774 * alloc.c (string_overflow): New function.
13775 (Fmake_string): Use it. This doesn't change behavior, but saves
13776 a few bytes and will simplify future changes.
13777 * character.c (string_escape_byte8): Likewise.
13778 * lisp.h (string_overflow): New decl.
13780 Fixups, following up to the user-interface timestamp change.
13781 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
13782 for UI timestamps, instead of unsigned long.
13783 * msdos.c (mouse_get_pos): Likewise.
13784 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
13785 * w32gui.h (Time): Define by including "systime.h" rather than by
13786 declaring it ourselves. (Bug#8664)
13788 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
13789 * image.c (clear_image_cache): Likewise.
13791 * term.c (term_mouse_position): Don't assume time_t wraparound.
13793 Be more systematic about user-interface timestamps.
13794 Before, the code sometimes used 'Time', sometimes 'unsigned long',
13795 and sometimes 'EMACS_UINT', to represent these timestamps.
13796 This change causes it to use 'Time' uniformly, as that's what X uses.
13797 This makes the code easier to follow, and makes it easier to catch
13798 integer overflow bugs such as Bug#8664.
13799 * frame.c (Fmouse_position, Fmouse_pixel_position):
13800 Use Time, not unsigned long, for user-interface timestamps.
13801 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
13802 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
13803 * keyboard.h (last_event_timestamp): Likewise.
13804 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
13805 * menu.h (xmenu_show): Likewise.
13806 * term.c (term_mouse_position): Likewise.
13807 * termhooks.h (struct input_event.timestamp): Likewise.
13808 (struct terminal.mouse_position_hook): Likewise.
13809 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
13810 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
13811 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
13812 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
13813 what it was before.
13814 * menu.h, termhooks.h: Include "systime.h", for Time.
13816 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
13817 Don't assume that the difference between two unsigned long values
13818 can fit into an integer. At this point, we know button_down_time
13819 <= event->timestamp, so the difference must be nonnegative, so
13820 there's no need to cast the result if double-click-time is
13821 nonnegative, as it should be; check that it's nonnegative, just in
13822 case. This bug is triggered when events are more than 2**31 ms
13823 apart (about 25 days). (Bug#8664)
13825 * xselect.c (last_event_timestamp): Remove duplicate decl.
13826 (x_own_selection): Remove needless cast to unsigned long.
13828 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
13829 that always fit in int. Use a sentinel instead of a counter, to
13830 avoid a temp and to allay GCC's concerns about possible int overflow.
13831 * frame.h (struct frame): Use int for menu_bar_items_used
13832 instead of EMACS_INT, since it always fits in int.
13834 * menu.c (grow_menu_items): Check for int overflow.
13836 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
13838 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
13839 Before, the code was not consistent. These values cannot exceed
13840 2**31 - 1 so there's no need to make them unsigned.
13841 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
13842 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
13843 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
13845 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
13847 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
13848 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
13849 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
13850 presumably because the widths might not match.
13852 * window.c (size_window): Avoid needless test at loop start.
13854 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
13856 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
13858 2011-05-12 Drew Adams <drew.adams@oracle.com>
13860 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
13862 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13864 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
13865 `width' to `bar_area_x' and `bar_area_width', respectively.
13866 (x_scroll_run): Take account of fringe background extension.
13868 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
13869 Rename local vars `left' and `width' to `bar_area_x' and
13870 `bar_area_width', respectively.
13871 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
13872 background extension.
13874 2011-05-10 Jim Meyering <meyering@redhat.com>
13876 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
13878 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
13880 * image.c (Finit_image_library): Return t for built-in image types,
13881 like pbm and xbm. (Bug#8640)
13883 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
13885 * w32menu.c (set_frame_menubar): Fix submenu allocation.
13887 2011-05-07 Eli Zaretskii <eliz@gnu.org>
13889 * w32console.c (Fset_screen_color): Doc fix.
13890 (Fget_screen_color): New function.
13891 (syms_of_ntterm): Defsubr it.
13893 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
13894 unlink the temporary file if Fcall_process didn't create it in the
13896 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
13897 child process will be redirected to a file specified with `:file'.
13898 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
13899 cue to call_process_cleanup not to close that handle.
13901 2011-05-07 Ben Key <bkey76@gmail.com>
13903 * makefile.w32-in: The bootstrap-temacs rule now makes use of
13904 one of two shell specific rules, either bootstrap-temacs-CMD or
13905 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
13906 to the previous implementation of the bootstrap-temacs rule.
13907 The bootstrap-temacs-CMD rule is similar to the previous
13908 implementation of the bootstrap-temacs rule except that it
13909 makes use of the ESC_CFLAGS variable instead of the CFLAGS
13912 These changes, along with some changes to nt/configure.bat,
13913 nt/gmake.defs, and nt/nmake.defs, are required to extend my
13914 earlier fix to add support for --cflags and --ldflags options
13915 that include quotes so that it works whether make uses cmd or
13918 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
13920 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
13921 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
13923 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
13924 a string. Handle both cases.
13925 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
13926 (Fdbus_register_method): Use Qinvalid_function.
13928 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
13930 * makefile.w32-in: Update dependencies.
13931 (LISP_H): Add inttypes.h and stdin.h.
13932 (PROCESS_H): Add unistd.h.
13934 2011-05-06 Eli Zaretskii <eliz@gnu.org>
13936 * lread.c: Include limits.h (fixes the MS-Windows build broken by
13937 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
13939 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
13941 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
13943 * term.c (vfatal): Remove stray call to va_end.
13944 It's not needed and the C Standard doesn't allow it here anyway.
13946 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
13947 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
13949 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
13952 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
13954 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13956 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
13958 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
13960 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
13962 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
13963 * charset.c (Fdefine_charset_internal): Don't initialize
13964 charset.code_space[15]. The value was garbage, on hosts with
13965 32-bit int (Bug#8600).
13967 * lread.c (read_integer): Be more consistent with string-to-number.
13968 Use string_to_number to do the actual conversion; this avoids
13969 rounding errors and fixes some other screwups. Without this fix,
13970 for example, #x1fffffffffffffff was misread as -2305843009213693952.
13971 (digit_to_number): Move earlier, for benefit of read_integer.
13972 Return -1 if the digit is out of range for the base, -2 if it is
13973 not a digit in any supported base. (Bug#8602)
13975 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13977 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13978 to match comment at start of function. This also removes a
13979 GCC warning about overflow in a 32+64-bit port.
13981 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
13983 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
13984 Reported by Stefan Monnier in
13985 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
13986 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13987 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
13989 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
13990 (EMACS_UINTPTR): Likewise, with uintptr_t.
13992 * lisp.h: Prefer 64-bit EMACS_INT if available.
13993 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
13994 on 32-bit hosts that have 64-bit int, so that they can access
13996 However, temporarily disable this change unless the temporary
13997 symbol WIDE_EMACS_INT is defined.
13999 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14001 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14002 This removes an assumption that EMACS_INT and long are the same
14003 width as pointers. The assumption is true for Emacs porting targets
14004 now, but we want to make other targets possible.
14005 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14006 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14007 In the rest of the code, change types of integers that hold casted
14008 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14009 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14010 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14011 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14012 No need to cast type when ORing.
14013 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14014 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14015 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14016 assume EMACS_INT is the same width as char *.
14017 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14018 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14019 Remove no-longer-needed casts.
14020 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14021 (xg_tool_bar_help_callback, xg_make_tool_item):
14022 Use EMACS_INTPTR to hold an integer
14023 that will be cast to void *; this can avoid a GCC warning
14024 if EMACS_INT is not the same width as void *.
14025 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14026 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14027 (current_message_1, set_message_1):
14028 Use a local to convert to proper width without a cast.
14029 * xmenu.c (dialog_selection_callback): Likewise.
14031 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14032 Also, don't assume VALBITS / RAND_BITS is less than 5,
14033 and don't rely on undefined behavior when shifting a 1 left into
14035 * lisp.h (get_random): Change signature to match.
14037 * lread.c (hash_string): Use size_t, not int, for hash computation.
14038 Normally we prefer signed values; but hashing is special, because
14039 it's better to use unsigned division on hash table sizes so that
14040 the remainder is nonnegative. Also, size_t is the natural width
14041 for hashing into memory. The previous code used 'int', which doesn't
14042 retain enough info to hash well into very large tables.
14043 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14045 * dbusbind.c: Don't possibly lose pointer info when converting.
14046 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14047 Use XPNTR rather than XHASH, so that the high-order bits of
14048 the pointer aren't lost when converting through void *.
14050 * eval.c (Fautoload): Don't double-shift a pointer.
14052 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14054 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14056 * gnutls.c (DEF_GNUTLS_FN):
14057 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14059 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14061 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14064 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14066 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14067 New version that can reserve upto 2GB of heap space.
14069 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14071 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14073 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14075 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14076 `gnutls_certificate_set_x509_key_file'.
14078 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14080 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14081 Update dependencies.
14083 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14085 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14086 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14087 Remove unused parameter `fildes'.
14088 * process.c (read_process_output, send_process): Don't pass it.
14090 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14092 Fix previous change: the library cache is defined in w32.c.
14093 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14094 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14096 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14098 Implement dynamic loading of GnuTLS on Windows.
14100 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14101 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14102 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14105 * gnutls.c (Qgnutls_dll): Define.
14106 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14107 (gnutls_*): Declare function pointers.
14108 (init_gnutls_functions): New function to initialize function pointers.

14111 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14112 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14113 (emacs_gnutls_write, emacs_gnutls_read)
14114 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14115 (Fgnutls_available_p): New function.
14116 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
14117 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
14118 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
14120 * image.c: Include w32.h.
14121 (Vimage_type_cache): Delete.

14124 (w32_delayed_load): Move to w32.c.
14126 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
14128 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14129 (w32_delayed_load): Move from image.c. When loading a library, record
14130 its filename in the :loaded-from property of the library id.
14131 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14132 Initialize and staticpro them.
14133 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14135 * process.c: Include lisp.h before w32.h, not after.
14136 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14137 instead of gnutls_record_check_pending.
14139 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14141 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14143 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14144 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14147 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14149 * xterm.c (x_set_frame_alpha): Do not set property on anything
14150 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14152 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14154 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14156 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14158 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14172 * sysdep.c (wait_for_termination_1): Make static.
14173 (wait_for_termination, interruptible_wait_for_termination):
14174 Move after wait_for_termination_1.
14176 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14178 * sysdep.c (interruptible_wait_for_termination): New function
14179 which is like wait_for_termination, but allows keyboard
14182 * callproc.c (Fcall_process): Add (:file "file") as an option for
14184 (Fcall_process_region): Ditto.
14186 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14188 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14189 rather than `XVECTOR (FOO)->size'.
14191 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14192 inttypes.h, as a gnulib replacement is used if it not available in
14195 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14197 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14198 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14199 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14201 * coding.c (coding_alloc_by_realloc): Error out if destination
14202 will grow beyond MOST_POSITIVE_FIXNUM.
14203 (decode_coding_emacs_mule): Abort if there isn't enough place in
14204 charbuf for the composition carryover bytes. Reserve an extra
14205 space for up to 2 characters produced in a loop.
14206 (decode_coding_iso_2022): Abort if there isn't enough place in
14207 charbuf for the composition carryover bytes.
14209 2011-04-21 Eli Zaretskii <eliz@gnu.org>

14212 aborting when %lld or %lll format is passed.
14213 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
14214 %llo or %llx format is passed. (Bug#8545)
14216 * window.c (window_scroll_line_based): Use a marker instead of
14217 simple variables to record original value of point. (Bug#7952)
14219 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14220 produced by %s or %c overflows available buffer space. (Bug#8545)
14222 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14224 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
14225 (SIZE_MAX): Move defn after all includes, as they might #define it.
14227 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
14229 * w32.c (init_environment): Warn about defaulting HOME to C:\.

14253 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
14255 * makefile.w32-in: Update dependencies.
14257 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14259 Improve `doprnt' and its usage. (Bug#8545)
14260 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14261 `format_end'. Remove support for %l as a conversion specifier.
14262 Don't use xrealloc. Improve diagnostics when the %l size modifier
14263 is used. Update the commentary.
14265 * eval.c (verror): Simplify calculation of size_t.
14267 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14270 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14272 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14275 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14277 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14278 This makes this file independent of the recent pseudovector change.
14280 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14282 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14284 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14285 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14286 Remove unused local.
14287 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14289 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14290 GCC 4.6.0 optimizes based on type-based alias analysis.
14291 For example, if b is of type struct buffer * and v of type struct
14292 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14293 != &v->size, and therefore "v->size = 1; b->size = 2; return
14294 v->size;" must therefore return 1. This assumption is incorrect
14295 for Emacs, since it type-puns struct Lisp_Vector * with many other
14296 types. To fix this problem, this patch adds a new type struct
14297 vectorlike_header that documents the constraints on layout of vectors
14298 and pseudovectors, and helps optimizing compilers not get fooled
14299 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14300 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14301 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14303 (XSETPVECTYPE): Rewrite in terms of new macro.
14304 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14305 This is a bit clearer, and further avoids the possibility of
14306 undesirable aliasing.
14307 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14308 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14309 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14310 since Lisp_Subr is a special case (no "next" field).
14311 (ASIZE): Now uses header.size rather than size.
14312 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14313 to avoid the hassle of writing XVECTOR (foo)->header.size.
14314 (struct vectorlike_header): New type.
14315 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14316 object, to help avoid aliasing.
14317 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14318 (SUBRP): Likewise, since Lisp_Subr is a special case.
14319 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14320 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14321 (struct Lisp_Hash_Table): Combine first two members into a single
14322 struct vectorlike_header member. All uses of "size" and "next" members
14323 changed to be "header.size" and "header.next".
14324 * buffer.h (struct buffer): Likewise.
14325 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14326 * frame.h (struct frame): Likewise.
14327 * process.h (struct Lisp_Process): Likewise.
14328 * termhooks.h (struct terminal): Likewise.
14329 * window.c (struct save_window_data, struct saved_window): Likewise.
14330 * window.h (struct window): Likewise.
14331 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14332 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14333 * buffer.c (init_buffer_once): Likewise.
14334 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14336 * process.c (Fformat_network_address): Use local var for size,
14339 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14341 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14342 * data.c (atof): Remove decl; no longer used or needed.
14343 (digit_to_number): Move to lread.c.
14344 (Fstring_to_number): Use new string_to_number function, to be
14345 consistent with how the Lisp reader treats infinities and NaNs.
14346 Do not assume that floating-point numbers represent EMACS_INT
14347 without losing information; this is not true on most 64-bit hosts.
14348 Avoid double-rounding errors, by insisting on integers when
14349 parsing non-base-10 numbers, as the documentation specifies.
14350 * lisp.h (string_to_number): New decl, replacing ...
14351 (isfloat_string): Remove.
14352 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14353 (read1): Do not accept +. and -. as integers; this
14354 appears to have been a coding error. Similarly, do not accept
14355 strings like +-1e0 as floating point numbers. Do not report
14356 overflow for integer overflows unless the base is not 10 which
14357 means we have no simple and reliable way to continue.
14358 Break out the floating-point parsing into a new
14359 function string_to_number, so that Fstring_to_number parses
14360 floating point numbers consistently with the Lisp reader.
14361 (digit_to_number): Move here from data.c. Make it static inline.
14362 (E_CHAR, EXP_INT): Remove, replacing with ...
14363 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14364 (string_to_number): New function, replacing isfloat_string.
14365 This function checks for valid syntax and produces the resulting
14366 Lisp float number too. Rework it so that string-to-number
14367 no longer mishandles examples like "1.0e+". Use strtoumax,
14368 so that overflow for non-base-10 numbers is reported only when
14369 there's no portable and simple way to convert to floating point.
14371 * textprop.c (set_text_properties_1): Rewrite for clarity,
14372 and to avoid GCC warning about integer overflow.
14374 * intervals.h (struct interval): Use EMACS_INT for members
14375 where EMACS_UINT might cause problems. See
14376 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14377 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14378 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14380 (offset_intervals): Tell GCC not to worry about length overflow
14381 when negating a negative length.
14383 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14384 (overrun_check_free): Likewise.
14386 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14387 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14390 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14391 (gnutls_make_error): Rename local to avoid shadowing.
14392 (gnutls_emacs_global_deinit): ifdef out; not used.
14393 (Fgnutls_boot): Use const for pointer to readonly storage.
14394 Comment out unused local. Fix pointer signedness problems.
14396 * lread.c (openp): Don't stuff size_t into an 'int'.
14397 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14398 about possible signed overflow.
14400 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14401 (GDK_KEY_g): Don't define if already defined.
14402 (xg_prepare_tooltip): Avoid pointer signedness problem.
14403 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14405 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14406 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14408 * xfns.c (Fx_window_property): Simplify a bit,
14409 to make a bit faster and to avoid GCC 4.6.0 warning.
14410 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14412 * fns.c (internal_equal): Don't assume size_t fits in int.
14414 * alloc.c (compact_small_strings): Tighten assertion a little.
14416 Replace pEd with more-general pI, and fix some printf arg casts.
14417 * lisp.h (pI): New macro, generalizing old pEd macro to other
14418 conversion specifiers. For example, use "...%"pI"d..." rather
14419 than "...%"pEd"...".
14420 (pEd): Remove. All uses replaced with similar uses of pI.
14421 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14422 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14423 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14424 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14425 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14426 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14427 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14429 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14430 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14431 * print.c (safe_debug_print, print_object): Likewise.
14432 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14434 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14435 avoiding the 0 flag, which is not portable.
14436 * process.c (Fmake_network_process): Use pI to avoid cast.
14437 * region-cache.c (pp_cache): Likewise.
14438 * xdisp.c (decode_mode_spec): Likewise.
14439 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14440 behavior on 64-bit hosts with printf arg.
14441 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14442 (x_stop_queuing_selection_requests): Likewise.
14443 (x_get_window_property): Don't truncate byte count to an 'int'
14446 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14447 here, since it parses constructs like leading '-' and spaces,
14448 which are not wanted; and it overflows with large numbers.
14449 Instead, simply match F[0-9]+, which is what is wanted anyway.
14451 * alloc.c: Remove unportable assumptions about struct layout.
14452 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14453 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14454 (allocate_vectorlike, make_pure_vector): Use the new macros,
14455 plus offsetof, to remove unportable assumptions about struct layout.
14456 These assumptions hold on all porting targets that I know of, but
14457 they are not guaranteed, they're easy to remove, and removing them
14458 makes further changes easier.
14460 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14461 This doesn't fix a bug but makes the code clearer.
14462 (string_overrun_cookie): Now const. Use initializers that
14463 don't formally overflow signed char, to avoid warnings.
14464 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14465 can cause Emacs to crash when string overrun checking is enabled.
14466 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14467 multiple of sizeof (EMACS_INT); it need not be, if
14468 alignof(EMACS_INT) < sizeof (EMACS_INT).
14469 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14471 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14478 supposed to be handshaking. (Bug#8556)
14479 Reported by Paul Eggert <eggert@cs.ucla.edu>.
14481 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
14483 * lisp.h (Qdebug): List symbol.
14484 * eval.c (Qdebug): Restore global linkage.

14492 (check_string_free_list): Convert to standard C.
14494 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14496 * w32.c (emacs_gnutls_push): Fix typo.
14498 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14500 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14501 "cast to pointer from integer of different size".
14503 Improve doprnt and its use in verror. (Bug#8545)
14504 * doprnt.c (doprnt): Document the set of format control sequences
14505 supported by the function. Use SAFE_ALLOCA instead of always
14508 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14509 is one byte too soon. Don't use xrealloc; instead xfree and
14512 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14514 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14517 * gnutls.c: Renamed global_initialized to
14518 gnutls_global_initialized. Added internals for the
14519 :verify-hostname-error, :verify-error, and :verify-flags
14520 parameters of `gnutls-boot' and documented those parameters in the
14521 docstring. Start callback support.
14522 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14523 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14524 on error. Return error code.

14584 changes in globals.h immediately force recompilation.
14585 (TAGS): Depend on $(CURDIR)/m/intel386.h and
14586 $(CURDIR)/s/ms-w32.h.

14596 * doprnt.c: Include limits.h.
14597 (SIZE_MAX): New macro.
14598 (doprnt): Return a size_t value. 2nd arg is now size_t.
14599 Many local variables are now size_t instead of int or unsigned.
14600 Improve overflow protection. Support `l' modifier for integer
14601 conversions. Support %l conversion. Don't assume an EMACS_INT
14602 argument for integer conversions and for %c.
14604 * lisp.h (doprnt): Restore prototype.
14606 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
14607 $(SRC)/character.h.
14609 * Makefile.in (base_obj): Add back doprnt.o.
14611 * deps.mk (doprnt.o): Add back prerequisites.
14612 (callint.o): Depend on character.h.
14614 * eval.c (internal_lisp_condition_case): Include the handler
14615 representation in the error message.
14616 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
14617 when breaking from the loop.
14619 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
14621 * callint.c (Fcall_interactively): When displaying error message
14622 about invalid control letter, pass the character's codepoint, not
14623 a pointer to its multibyte form. Improve display of the character
14624 in octal and display also its hex code.
14626 * character.c (char_string): Use %x to display the (unsigned)
14627 codepoint of an invalid character, to avoid displaying a bogus
14630 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
14631 `error', not SYMBOL_NAME itself.
14633 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
14634 character arguments to `error'.
14636 * charset.c (check_iso_charset_parameter): Fix incorrect argument
14637 to `error' in error message about FINAL_CHAR argument. Make sure
14638 FINAL_CHAR is a character, and use %c when it is passed as
14639 argument to `error'.

14703 Define only if needed.
14705 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
14706 by pacifying GCC about it. Maybe it's time to retire it?
14707 * xfaces.c (USG, __TIMEVAL__): Likewise.
14709 * dispextern.h (struct redisplay_interface): Rename param
14710 to avoid shadowing.
14711 * termhooks.h (struct terminal): Likewise.
14712 * xterm.c (xembed_send_message): Likewise.
14714 * insdel.c (make_gap_smaller): Define only if
14715 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
14717 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
14720 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
14721 so that we aren't warned about unused symbols.
14723 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
14725 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
14727 * xfns.c (x_real_positions): Mark locals as initialized.
14729 * xmenu.c (xmenu_show): Don't use uninitialized vars.

14732 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
14733 (x_dispatch_event): Declare static if USE_GTK, and
14734 define if USE_GTK || USE_X_TOOLKIT.
14735 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
14736 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
14737 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
14738 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
14740 * xmenu.c (menu_help_callback): Pointer type fixes.
14741 Use const pointers when pointing at readonly data. Avoid pointer

14757 * bitmaps: Change bitmaps from unsigned char back to the X11
14758 compatible char. Avoid the old compiler warnings about
14759 out-of-range initializers by using, for example, '\xab' rather
14762 * xgselect.c (xgselect_initialize): Check vs interface
14763 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

14833 --enable-checking=xmallocoverrun). xfree is now used to
14834 deallocate these memory blocks.

15212 (message_enable_multibyte): Remove decl.
15213 (free_misc, interval_free_list, float_block, float_block_index):
15214 (n_float_blocks, float_free_list, cons_block, cons_block_index):
15215 (cons_free_list, last_marked_index):
15217 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
15218 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15219 (mark_backtrace): Define only if BYTE_MARK_STACK.
15220 * xdisp.c (message_enable_multibyte): Now static.
15222 Declare Lisp_Object Q* variables to be 'static' if not exported.
15223 This makes it easier for human readers (and static analyzers)
15224 to see whether these variables are used from other modules.
15225 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15226 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15227 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
15228 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
15229 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
15230 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15231 * xmenu.c, xselect.c:
15232 Declare Q* vars static if they are not used in other modules.
15233 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15234 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15235 Remove decls of unexported vars.
15236 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15238 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15240 Make Emacs functions such as Fatom 'static' by default.
15241 This makes it easier for human readers (and static analyzers)
15242 to see whether these functions can be called from other modules.
15243 DEFUN now defines a static function. To make the function external
15244 so that it can be used in other C modules, use the new macro DEFUE.
15245 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15246 (Finit_image_library):
15247 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15248 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15249 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15250 Remove decls, since these functions are now static.
15251 (Funintern, Fget_internal_run_time): New decls, since these functions
15252 were already external.
15254 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15255 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15256 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15257 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15258 * keyboard.c, keymap.c, lread.c:
15259 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15260 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15261 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15262 Mark functions with DEFUE instead of DEFUN,
15263 if they are used in other modules.
15264 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15265 decls for now-static functions.
15266 * buffer.h (Fdelete_overlay): Remove decl.
15267 * callproc.c (Fgetenv_internal): Mark as internal.
15268 * composite.c (Fremove_list_of_text_properties): Remove decl.

15271 * dired.c (Ffile_attributes): New forward static decl.
15272 * doc.c (Fdocumntation_property): New forward static decl.
15273 * eval.c (Ffetch_bytecode): New forward static decl.
15274 (Funintern): Remove extern decl; now in .h file where it belongs.
15275 * fileio.c (Fmake_symbolic_link): New forward static decl.
15276 * image.c (Finit_image_library): New forward static decl.
15277 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15278 * intervals.h (Fprevious_property_change):
15279 (Fremove_list_of_text_properties): Remove decls.
15280 * keyboard.c (Fthis_command_keys): Remove decl.
15281 (Fcommand_execute): New forward static decl.
15282 * keymap.c (Flookup_key): New forward static decl.
15283 (Fcopy_keymap): Now static.
15284 * keymap.h (Flookup_key): Remove decl.
15285 * process.c (Fget_process): New forward static decl.
15286 (Fprocess_datagram_address): Mark as internal.
15287 * syntax.c (Fsyntax_table_p): New forward static decl.
15288 (skip_chars): Remove duplicate decl.
15289 * textprop.c (Fprevious_property_change): New forward static decl.
15290 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
15292 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
15293 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
15295 * editfns.c (Fformat): Remove unreachable code.
15297 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15299 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15302 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15304 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15305 when at ZV. (Bug#8487)
15307 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15309 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15311 * keyboard.c (parse_tool_bar_item): Likewise.
15312 * sound.c (sound_cleanup, alsa_close): Likewise.
15313 * termcap.c (tgetent): Likewise.
15314 * xfns.c (x_default_font_parameter): Likewise.
15315 * xsettings.c (read_and_apply_settings): Likewise.
15317 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15318 (overrun_check_free): Protoize.
15320 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15322 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15323 since callers should never pass a negative size.
15324 Change the signature to match that of plain 'read' and 'write'; see
15325 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15326 * lisp.h: Update prototypes of emacs_write and emacs_read.
15328 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15330 * xdisp.c (redisplay_window): Don't try to determine the character
15331 position of the scroll margin if the window start point w->startp
15332 is outside the buffer's accessible region. (Bug#8468)
15334 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15336 Fix write-region and its subroutines for buffers > 2GB.
15337 * fileio.c (a_write, e_write): Modify declaration of arguments and
15338 local variables to support buffers larger than 2GB.
15339 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15341 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15342 argument, local variables, and return value.
15344 * lisp.h: Update prototypes of emacs_write and emacs_read.
15346 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15348 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15350 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15352 Fix more problems found by GCC 4.6.0's static checks.
15354 * xdisp.c (vmessage): Use a better test for character truncation.
15356 * charset.c (load_charset_map): <, not <=, for optimization,
15357 and to avoid potential problems with integer overflow.
15358 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15359 * casetab.c (set_identity, shuffle): Likewise.
15360 * editfns.c (Fformat): Likewise.
15361 * syntax.c (skip_chars): Likewise.
15363 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15364 This also lets GCC 4.6.0 generate slightly better loop code.
15366 * callint.c (Fcall_interactively): <, not <=, for optimization.
15367 (Fcall_interactively): Count the number of arguments produced,
15368 not the number of arguments given. This is simpler and lets GCC
15369 4.6.0 generate slightly better code.
15371 * ftfont.c: Distingish more carefully between FcChar8 and char.
15372 The previous code passed unsigned char * to a functions like
15373 strlen and xstrcasecmp that expect char *, which does not
15374 conform to the C standard.
15375 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15376 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15377 char * when the C standard requires it.
15379 * keyboard.c (read_char): Remove unused var.
15381 * eval.c: Port to Windows vsnprintf (Bug#8435).
15382 Include <limits.h>.
15383 (SIZE_MAX): Define if the headers do not.
15384 (verror): Do not give up if vsnprintf returns a negative count.
15385 Instead, grow the buffer. This ports to Windows vsnprintf, which
15386 does not conform to C99. Problem reported by Eli Zaretskii.
15387 Also, simplify the allocation scheme, by avoiding the need for
15388 calling realloc, and removing the ALLOCATED variable.
15390 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15392 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15393 But keep the doprint source code for now, as we might revamp it
15394 and use it again (Bug#8435).
15395 * lisp.h (doprnt): Remove.
15396 * Makefile.in (base_obj): Remove doprnt.o.
15397 * deps.mk (doprnt.o): Remove.
15399 error: Print 32- and 64-bit integers portably (Bug#8435).
15400 Without this change, on typical 64-bit hosts error ("...%d...", N)
15401 was used to print both 32- and 64-bit integers N, which relied on
15402 undefined behavior.
15403 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15404 * lisp.h (error, verror): Mark as printf-like functions.
15405 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15406 Report overflow in size calculations when allocating printf buffer.
15407 Do not truncate output string at its first null byte.
15408 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15409 Truncate the output at a character boundary, since vsnprintf does not
15411 * charset.c (check_iso_charset_parameter): Convert internal
15412 character to string before calling 'error', since %c now has the
15414 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15415 overflow when computing char to be passed to 'error'. Do not
15416 pass Lisp_Object to 'error'; pass the integer instead.
15417 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15418 formatted with plain %d.
15420 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15422 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15424 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15426 * xterm.c (x_catch_errors): Remove duplicate declaration.
15428 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15430 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15432 2011-04-10 Jim Meyering <meyering@redhat.com>
15434 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15435 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15436 return ssize_t not "int", and use size_t as the buffer length.
15437 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15438 * gnutls.h: Update declarations.
15439 * process.c (read_process_output): Use ssize_t, to match.
15440 (send_process): Likewise.
15442 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15444 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15446 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15448 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15449 Use unsigned char, to match FcChar8 type definition.
15451 * xterm.c (handle_one_xevent):
15452 * xmenu.c (create_and_show_popup_menu):
15453 * xselect.c (x_decline_selection_request)
15454 (x_reply_selection_request): Avoid type-punned deref of X events.
15456 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15458 Fix some uses of `int' instead of EMACS_INT.
15459 * search.c (string_match_1, fast_string_match)
15460 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15461 (scan_buffer, find_next_newline_no_quit)
15462 (find_before_next_newline, search_command, Freplace_match)
15463 (Fmatch_data): Make some `int' variables be EMACS_INT.
15465 * xdisp.c (display_count_lines): 3rd argument and return value now
15466 EMACS_INT. All callers changed.
15467 (pint2hrstr): Last argument is now EMACS_INT.
15469 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15470 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15471 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15472 (decode_coding_utf_16, decode_coding_emacs_mule)
15473 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15474 (decode_coding_ccl, decode_coding_charset)
15475 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15476 (decode_coding_iso_2022, decode_coding_emacs_mule)
15477 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15478 <char_offset, last_offset>: Declare EMACS_INT.
15479 (encode_coding_utf_8, encode_coding_utf_16)
15480 (encode_coding_emacs_mule, encode_invocation_designation)
15481 (encode_designation_at_bol, encode_coding_iso_2022)
15482 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15483 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15485 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15486 (encode_invocation_designation): Last argument P_NCHARS is now
15488 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15489 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15491 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15494 * ccl.c (Fccl_execute_on_string): Declare some variables
15497 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15499 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15501 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15503 * process.c (Fformat_network_address): Doc fix.
15505 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15507 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15509 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15511 * keyboard.c (read_char): Call Lisp function help-form-show,
15512 instead of using internal_with_output_to_temp_buffer.
15513 (Qhelp_form_show): New var.
15514 (syms_of_keyboard): Use DEFSYM macro.
15516 * print.c (internal_with_output_to_temp_buffer): Function deleted.

15520 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15522 * process.c (Flist_processes): Remove to Lisp.
15523 (list_processes_1): Delete.
15525 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15527 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15529 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15531 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15533 Fix more problems found by GCC 4.6.0's static checks.
15535 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15537 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15539 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15541 * xdisp.c (vmessage): Mark as a printf-like function.
15543 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15545 * sound.c (sound_warning): Don't crash if arg contains a printf format.
15547 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
15548 printf-like functions.
15549 (tiff_load): Add casts to remove these marks before passing them
15550 to system-supplied API.
15552 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15554 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15555 This avoids several warnings with gcc -Wstrict-overflow.
15556 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15557 directly, rather than having caller test rule sign. This avoids
15558 some unnecessary tests.
15559 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15560 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15561 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15563 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15564 (xfont_open): Avoid unnecessary tests.
15566 * composite.c (composition_gstring_put_cache): Use unsigned integer.
15568 * composite.h, composite.c (composition_gstring_put_cache):
15569 Use EMACS_INT, not int, for length.
15571 * composite.h (COMPOSITION_DECODE_REFS): New macro,
15572 breaking out part of COMPOSITION_DECODE_RULE.
15573 (COMPOSITION_DECODE_RULE): Use it.
15574 * composite.c (get_composition_id): Remove unused local vars,
15575 by using the new macro.
15577 * textprop.c (set_text_properties_1): Change while to do-while,
15578 since the condition is always true at first.
15580 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15581 (interval_deletion_adjustment): Return unsigned value.
15584 * process.c (list_processes_1, create_pty, read_process_output):
15585 (exec_sentinel): Remove vars that were set but not used.
15586 (create_pty): Remove unnecessary "volatile"s.
15587 (Fnetwork_interface_info): Avoid possibility of int overflow.

15589 (read_process_output): Simplify nbytes computation if buffered.
15591 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
15593 * syntax.c (scan_words): Remove var that was set but not used.
15594 (update_syntax_table): Use unsigned instead of int.

15597 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15598 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
15600 * print.c (print_error_message): Avoid int overflow.
15602 * font.c (font_list_entities): Redo for clarity,
15603 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15605 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15606 (font_score): Avoid potential overflow in diff calculation.
15608 * fns.c (substring_both): Remove var that is set but not used.
15609 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15611 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15613 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15614 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15615 can always succeed if overflow has undefined behavior.
15617 * search.c (boyer_moore, wordify): Remove vars set but not used.
15618 (wordify): Omit three unnecessary tests.
15620 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15621 All callers changed. This avoids the need for an unused var.
15623 * casefiddle.c (casify_region): Remove var that is set but not used.
15625 * dired.c (file_name_completion): Remove var that is set but not used.
15627 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
15629 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
15630 (Finsert_file_contents): Remove unnecessary code checking fd.
15632 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
15633 Check for integer overflow on size calculations.
15635 * buffer.c (Fprevious_overlay_change): Remove var that is set
15638 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
15639 Remove vars that are set but not used.
15640 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
15641 (timer_check_2): Mark vars as initialized.
15643 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
15645 * image.c (lookup_image): Remove var that is set but not used.
15646 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
15648 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
15649 that are set but not used.
15651 * xfns.c (make_invisible_cursor): Don't return garbage
15652 if XCreateBitmapFromData fails (Bug#8410).
15654 * xselect.c (x_get_local_selection, x_handle_property_notify):
15655 Remove vars that are set but not used.
15657 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

15661 Remove var that is set but not used.
15662 (scroll_bar_windows_size): Now size_t, not int.
15663 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
15664 Check for overflow.
15666 * xfaces.c (realize_named_face): Remove vars that are set but not used.
15667 (map_tty_color) [!defined MSDOS]: Likewise.
15669 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
15671 * coding.c: Remove vars that are set but not used.
15672 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

15679 that is set but not used.
15681 * print.c (print_object): Remove var that is set but not used.
15683 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
15684 The gnulib version avoids calling malloc in the usual case,
15685 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
15686 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
15687 * filelock.c (current_lock_owner): Likewise.
15688 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
15689 * sysdep.c: Include allocator.h, careadlinkat.h.
15690 (emacs_no_realloc_allocator): New static constant.
15691 (emacs_readlink): New function.
15692 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
15693 ../lib/careadlinkat.h.
15695 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
15697 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

15719 do not dereference NULL upon failed strdup
15720 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
15721 (ns_get_family): Likewise.
15723 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
15725 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
15727 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
15729 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
15732 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
15734 Add lexical binding.
15736 * window.c (Ftemp_output_buffer_show): New fun.

15745 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
15747 (syms_of_lread): Declare `lexical-binding'.
15749 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
15751 * keyboard.c (eval_dyn): New fun.
15752 (menu_item_eval_property): Use it.
15754 * image.c (parse_image_spec): Use Ffunctionp.
15756 * fns.c (concat, mapcar1): Accept byte-code-functions.
15758 * eval.c (Fsetq): Handle lexical vars.
15759 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
15760 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
15761 (FletX, Flet): Obey lexical binding.
15762 (Fcommandp): Handle closures.
15763 (Feval): New `lexical' arg.
15764 (eval_sub): New function extracted from Feval. Use it almost
15765 everywhere where Feval was used. Look up vars in lexical env.
15767 (Ffunctionp): Move from subr.el.
15768 (Ffuncall): Handle closures.
15769 (apply_lambda): Remove `eval_flags'.
15770 (funcall_lambda): Handle closures and new byte-code-functions.
15771 (Fspecial_variable_p): New function.
15772 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
15773 but without exporting it to Lisp.
15775 * doc.c (Fdocumentation, store_function_docstring):
15776 * data.c (Finteractive_form): Handle closures.
15778 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
15781 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
15783 (exec_byte_code): New function extracted from Fbyte_code to handle new
15784 calling convention for byte-code-functions. Add new byte-codes.
15786 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
15788 * alloc.c (Fmake_symbol): Init new `declared_special' field.
15790 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
15792 * xdisp.c (redisplay_internal): Fix prototype.
15794 2011-03-31 Eli Zaretskii <eliz@gnu.org>
15796 * xdisp.c (SCROLL_LIMIT): New macro.
15797 (try_scrolling): Use it when setting scroll_limit.
15798 Limit scrolling to 100 screen lines.
15799 (redisplay_window): Even when falling back on "recentering",
15800 position point in the window according to scroll-conservatively,
15801 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
15803 (try_scrolling): When point is above the window, allow searching
15804 as far as scroll_max, or one screenful, to compute vertical
15805 distance from PT to the scroll margin position. This prevents
15806 try_scrolling from unnecessarily failing when
15807 scroll-conservatively is set to a value slightly larger than the
15808 window height. Clean up the case of PT below the margin at bottom
15809 of window: scroll_max can no longer be INT_MAX. When aggressive
15810 scrolling is in use, don't let point enter the opposite scroll
15811 margin as result of the scroll.
15812 (syms_of_xdisp) <scroll-conservatively>: Document the
15813 threshold of 100 lines for never-recentering scrolling.

15820 (message_log_check_duplicate): Remove parameters `prev_bol' and
15821 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
15822 (redisplay_internal): Remove parameter `preserve_echo_area',
15823 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
15825 * indent.c (Fvertical_motion):
15826 * window.c (window_scroll_pixel_based, Frecenter):
15827 Don't pass `need_y_p' to `move_it_by_lines'.
15829 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
15831 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
15832 steal a few bits to be more compact.
15833 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
15834 Remove unneeded casts.
15836 * bytecode.c (Fbyte_code): CAR and CDR can GC.
15838 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
15840 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
15841 binding" message (bug#7967).
15843 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
15845 Fix more problems found by GCC 4.6.0's static checks.
15847 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
15848 Remove unused local var.
15850 * editfns.c (Fmessage_box): Remove unused local var.
15852 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
15853 (note_mode_line_or_margin_highlight, note_mouse_highlight):
15854 Omit unused local vars.
15855 * window.c (shrink_windows): Omit unused local var.
15856 * menu.c (digest_single_submenu): Omit unused local var.
15857 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
15858 Omit unused local var.
15860 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
15861 Don't assume string length fits in int.
15862 (keyremap_step, read_key_sequence): Use size_t for sizes.

15866 instead of alloca (Bug#8344).
15868 * eval.c (Fbacktrace): Don't assume nargs fits in int.
15869 (Fbacktrace_frame): Don't assume nframes fits in int.
15871 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

15878 * cm.c (calccost): Turn while-do into do-while, for clarity.
15880 * keyboard.c (syms_of_keyboard): Use the same style as later
15881 in this function when indexing through an array. This also
15882 works around GCC bug 48267.
15884 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
15886 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
15888 * chartab.c (sub_char_table_ref_and_range): Redo for slight
15889 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
15891 * keyboard.c, keyboard.h (num_input_events): Now size_t.
15892 This avoids undefined behavior on integer overflow, and is a bit
15893 more convenient anyway since it is compared to a size_t variable.
15895 Variadic C functions now count arguments with size_t, not int.
15896 This avoids an unnecessary limitation on 64-bit machines, which
15897 caused (substring ...) to crash on large vectors (Bug#8344).

15907 * fns.c (concat): Likewise.
15908 * frame.c (x_set_frame_parameters): Likewise.
15909 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
15910 0 if not found, not -1. All callers changed.
15912 * alloc.c (garbage_collect): Don't assume stack size fits in int.
15913 (stack_copy_size): Now size_t, not int.
15914 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

15938 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
15939 Vcommand_hook_internal.

16082 * w32term.c (x_set_glyph_string_clipping):
16083 Don't pass uninitialized region to CombineRgn.
16085 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
16087 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
16088 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
16089 (Fx_close_connection): Remove unused variable `i'.

16107 2011-03-23 Julien Danjou <julien@danjou.info>
16109 * term.c (Fsuspend_tty, Fresume_tty):
16110 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16111 * window.c (temp_output_buffer_show):
16112 * insdel.c (signal_before_change):
16113 * frame.c (Fhandle_switch_frame):
16114 * fileio.c (Fdo_auto_save):
16115 * emacs.c (Fkill_emacs):
16116 * editfns.c (save_excursion_restore):
16117 * cmds.c (internal_self_insert):
16118 * callint.c (Fcall_interactively):
16119 * buffer.c (Fkill_all_local_variables):
16120 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16122 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16123 unconditionally since it does the check itself.
16125 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16127 Fix more problems found by GCC 4.5.2's static checks.
16129 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16130 the first time through the loop, since we know p0 < p1 then.
16131 This also avoids a gcc -Wstrict-overflow warning.
16133 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16134 leading to a memory leak, possible in functions like
16135 load_charset_map_from_file that can allocate an unbounded number
16136 of objects (Bug#8318).
16138 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16139 that could (at least in theory) be that large.
16141 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16142 This is less likely to overflow, and avoids undefined behavior if
16143 overflow does occur. All callers changed. Use strtoul to scan
16144 for the unsigned long integer.
16145 (pint2hrstr): Simplify and tune code slightly.
16146 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16148 * scroll.c (do_scrolling): Work around GCC bug 48228.
16149 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16151 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16152 This also avoids a warning with gcc -Wstrict-overflow.
16153 (validate_x_resource_name): Simplify count usage.
16154 This also avoids a warning with gcc -Wstrict-overflow.
16156 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16159 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16161 * process.c (Fmake_network_process): Use socklen_t, not int,
16162 where POSIX says socklen_t is required in portable programs.
16163 This fixes a porting bug on hosts like 64-bit HP-UX, where
16164 socklen_t is wider than int (Bug#8277).
16165 (Fmake_network_process, server_accept_connection):
16166 (wait_reading_process_output, read_process_output):
16169 * process.c: Rename or move locals to avoid shadowing.

16179 Make tparam.h and terminfo.c consistent.
16180 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16181 Include tparam.h instead, since it declares them.
16182 * cm.h (PC): Remove extern decl; tparam.h now does this.
16183 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16184 * terminfo.c: Include tparam.h, to check interfaces.
16185 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16186 (tparam): Adjust signature to match interface in tparam.h;
16187 this removes some undefined behavior. Check that outstring and len
16188 are zero, which they always are with Emacs.
16189 * tparam.h (PC, BC, UP): New extern decls.
16191 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16192 (xftfont_open): Rename locals to avoid shadowing.
16194 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16195 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
16196 (OTF_TAG_SYM): Omit macro if not needed.

16199 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
16200 Rename locals to avoid shadowing.
16202 * xfont.c (xfont_list_family): Mark var as initialized.
16204 * xml.c (make_dom): Now static.
16206 * composite.c (composition_compute_stop_pos): Rename local to
16208 (composition_reseat_it): Remove unused locals.
16209 (find_automatic_composition, composition_adjust_point): Likewise.
16210 (composition_update_it): Mark var as initialized.
16211 (find_automatic_composition): Mark vars as initialized,
16212 with a FIXME (Bug#8290).
16214 character.h: Rename locals to avoid shadowing.
16215 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16216 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16217 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16218 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16219 to avoid shadowing.
16221 * textprop.c (property_change_between_p): Remove; unused.
16223 * intervals.c (interval_start_pos): Now static.
16225 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

16228 Rename locals to avoid shadowing.
16230 * sound.c (wav_play, au_play, Fplay_sound_internal):
16231 Fix pointer signedness.
16232 (alsa_choose_format): Remove unused local var.
16233 (wav_play): Initialize a variable to 0, to prevent undefined
16234 behavior (Bug#8278).
16236 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16238 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16240 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16241 clobbering (Bug#8298).
16242 * sysdep.c (sys_subshell): Likewise.
16243 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16245 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16246 This should get cleaned up, so that child_setup has the
16247 same signature on all platforms.
16249 * callproc.c (call_process_cleanup): Now static.
16250 (relocate_fd): Rename locals to avoid shadowing.
16252 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16254 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16255 not to be necessary, and produces flickering.
16257 2011-03-20 Glenn Morris <rgm@gnu.org>
16259 * config.in: Remove file.
16261 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16263 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16264 are now in src/globals.h.
16265 (syms_of_minibuf): Remove spurious & from previous change.
16267 2011-03-20 Leo Liu <sdl.web@gmail.com>
16269 * minibuf.c (completing-read-function): New variable.
16270 (completing-read-default): Rename from completing-read.
16271 (completing-read): Call completing-read-function.
16273 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16275 * xfaces.c (Fx_load_color_file):
16276 Read color file from absolute filename (bug#8250).
16278 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16280 * makefile.w32-in: Update dependencies.
16282 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16284 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

16290 * process.c (make_serial_process_unwind, send_process_trap):
16291 (sigchld_handler): Now static.
16293 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16294 That way, the code declares only the vars that it needs.
16295 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16296 * s/cygwin.h (PTY_ITERATION): Likewise.
16297 * s/darwin.h (PTY_ITERATION): Likewise.

16301 * process.c (allocate_pty): Don't declare stb unless it's needed.
16303 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
16304 (CONSTANTLIM): Remove; unused.
16305 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16306 Define only if needed.
16308 * unexelf.c (unexec): Name an expression,
16309 to avoid gcc -Wbad-function-cast warning.
16310 Use a different way to cause a compilation error if anyone uses
16311 n rather than nn, a way that does not involve shadowing.
16312 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16314 * deps.mk (unexalpha.o): Remove; unused.
16316 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16317 * unexec.h: New file.
16318 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16319 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16320 Depend on unexec.h.
16321 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16322 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16323 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16324 Change as necessary to match prototype in unexec.h.
16326 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
16328 (back_comment, skip_chars): Mark vars as initialized.
16330 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

16336 * print.c (Fredirect_debugging_output): Fix pointer signedess.
16338 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
16339 warning when compiling print.c.

16342 instead of using an uninitialized var.
16343 (font_sort_entities): Mark var as initialized.
16345 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16347 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16359 * floatfns.c (domain_error2): Define only if needed.
16360 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
16362 * alloc.c (mark_backtrace): Move decl from here ...
16363 * lisp.h: ... to here, so that it can be checked.
16365 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
16366 (Fdefvar): Rewrite so as not to use empty "else".
16367 (lisp_indirect_variable): Name an expression,
16368 to avoid gcc -Wbad-function-cast warning.
16369 (Fdefvar): Rename locals to avoid shadowing.
16371 * callint.c (quotify_arg, quotify_args): Now static.
16372 (Fcall_interactively): Rename locals to avoid shadowing.
16373 Use const pointer when appropriate.
16375 * lisp.h (get_system_name, get_operating_system_release):
16376 Move decls here, to check interfaces.
16377 * process.c (get_operating_system_release): Move decl to lisp.h.
16378 * xrdb.c (get_system_name): Likewise.
16379 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16380 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16381 some of which prompt warnings from gcc -Wbad-function-cast.
16382 (Fformat_time_string, Fencode_time, Finsert_char):
16383 (Ftranslate_region_internal, Fformat):
16384 Rename or remove local vars to avoid shadowing.
16385 (Ftranslate_region_internal): Mark var as initialized.
16387 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16390 * lisp.h (eassert): Check that the argument compiles, even if
16391 ENABLE_CHECKING is not defined.
16393 * data.c (Findirect_variable): Name an expression, to avoid
16394 gcc -Wbad-function-cast warning.
16395 (default_value, arithcompare, arith_driver, arith_error): Now static.
16396 (store_symval_forwarding): Rename local to avoid shadowing.
16397 (Fmake_variable_buffer_local, Fmake_local_variable):

16402 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
16403 Rename locals to avoid shadowing.
16404 (mark_stack): Move local variables into the #ifdef region where
16406 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16407 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16409 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16410 (GC_STRING_CHARS): Remove; not used.
16411 (Fmemory_limit): Cast sbrk's returned value to char *.
16413 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16414 avoids undefined behavior in theory.
16416 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16418 Use functions, not macros, for up- and down-casing (Bug#8254).
16419 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16420 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16421 to use the following functions instead of these macros.
16422 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16423 EMACS_INT, since callers assume the returned value fits in int.
16424 (upcase1): Likewise, for UPCASE_TABLE.
16425 (uppercasep, lowercasep, upcase): New static inline functions.
16426 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16427 the race-condition problem in the old DOWNCASE.
16429 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
16430 Rename locals to avoid shadowing.
16431 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16432 (regex_compile, re_search_2, re_match_2_internal):
16433 Remove unused local vars.
16434 (FREE_VAR): Rewrite so as not to use empty "else",
16435 which gcc can warn about.
16436 (regex_compile, re_match_2_internal): Mark locals as initialized.
16437 (RETALLOC_IF): Define only if needed.
16438 (WORDCHAR_P): Likewise. This one is never needed, but is used
16439 only in a comment talking about a compiler bug, so put inside
16440 the #if 0 of that comment.
16441 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16442 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16445 * search.c (boyer_moore): Rename locals to avoid shadowing.
16446 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16447 (PREV_CHAR_BOUNDARY): Likewise.
16449 * search.c (simple_search): Remove unused var.
16451 * dired.c (compile_pattern): Move decl from here ...

16455 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
16457 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16459 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16460 Rename locals to avoid shadowing.
16461 (Fvertical_motion): Mark locals as initialized.
16463 * casefiddle.c (casify_object, casify_region): Now static.
16464 (casify_region): Mark local as initialized.
16466 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16468 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16469 New macros, so that the caller can use some names other than
16470 gcpro1, gcpro2, etc.
16471 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16473 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16474 argument, for consistency with GCPRO2_VAR, etc: it is now the
16475 prefix of the variable, not the variable itself. All uses
16477 * dired.c (directory_files_internal, file_name_completion):
16478 Rename locals to avoid shadowing.
16480 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16481 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16482 dired.c's scmp function, had undefined behavior.
16483 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16484 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16485 * buffer.h: ... to here, because these macros use current_buffer,
16486 and the new implementation with inline functions needs to have
16487 current_buffer in scope now, rather than later when the macros
16489 (downcase, upcase1): New static inline functions.
16490 (DOWNCASE, UPCASE1): Reimplement using these functions.
16491 This avoids undefined behavior in expressions like
16492 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16493 from race conditions in accessing the global variables
16494 case_temp1 and case_temp2.
16495 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16496 * lisp.h (case_temp1, case_temp2): Remove their decls.
16497 * character.h (ASCII_CHAR_P): Move from here ...
16498 * lisp.h: ... to here, so that the inline functions mentioned
16499 above can use them.
16501 * dired.c (directory_files_internal_unwind): Now static.
16503 * fileio.c (file_name_as_directory, directory_file_name):
16504 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16506 (file_name_as_directory): Use const pointers when appropriate.
16507 (Fexpand_file_name): Likewise. In particular, newdir might
16508 point at constant storage, so make it a const pointer.
16509 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16510 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16512 (Fset_file_times, Finsert_file_contents, auto_save_error):
16513 Rename locals to avoid shadowing.
16515 * minibuf.c (choose_minibuf_frame_1): Now static.
16516 (Ftry_completion, Fall_completions): Rename or remove locals
16517 to avoid shadowing.
16519 * marker.c (bytepos_to_charpos): Remove; unused.
16521 * lisp.h (verify_bytepos, count_markers): New decls,
16522 so that gcc does not warn that these functions aren't declared.
16524 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16525 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16526 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16527 (copy_text): Remove unused local var.
16529 * filelock.c (within_one_second): Now static.
16530 (lock_file_1): Rename local to avoid shadowing.
16532 * buffer.c (fix_overlays_before): Mark locals as initialized.
