51 2012-07-11 Glenn Morris <rgm@gnu.org>
53 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
54 since nothing has defined it on these platforms.

125 EMACS_TIME simplification (Bug#11875).
126 This replaces macros (which typically do not work in GDB)
127 with functions, typedefs and enums, making the code easier to debug.
128 The functional style also makes code easier to read and maintain.
129 * systime.h: Include <sys/time.h> on all hosts, not just if
130 WINDOWSNT, since 'struct timeval' is needed in general.
131 (EMACS_TIME): Now a typedef, not a macro.

142 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
143 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
144 not functions. All uses rewritten to use the following, respectively:
145 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
146 (add_emacs_time, sub_emacs_time): New functions.
147 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

149 * xterm.c (XTflash): Get the current time closer to when it's used.
150 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

161 * regex.c (regerror):
162 Prefer memcpy to strncpy and strncat when either will do.
163 * fileio.c (Fsubstitute_in_file_name):
164 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
165 (menu_separator_name_p):
166 * nsmenu.m (ns_update_menubar):
167 Prefer memcmp to strncmp when either will do.
168 * nsterm.m: Include <ftoastr.h>.
170 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
171 Prefer snprintf to strncpy.
172 * nsterm.m (ns_term_init):
173 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
174 * nsterm.m (ns_term_init):
175 Avoid the need for strncpy, by using build_string or
176 make_unibyte_string directly. Use dtoastr, not snprintf.
177 * process.c (Fmake_network_process): Diagnose service names that
178 are too long, rather than silently truncating them or creating
179 non-null-terminated names.
180 (Fnetwork_interface_info): Likewise, for interface names.
181 * sysdep.c (system_process_attributes) [GNU_LINUX]:
182 Prefer sprintf to strncat.
183 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

189 Clarify fallback case.
191 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

194 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
195 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
196 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
197 where argument type is known to be a Lisp_Cons.
199 2012-07-10 Tom Tromey <tromey@redhat.com>
201 * bytecode.c (BYTE_CODE_THREADED): New macro.
202 (BYTE_CODES): New macro. Replaces all old byte-code defines.
203 (enum byte_code_op): New type.
204 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
205 (exec_byte_code): Use them. Use token threading when applicable.
207 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
209 Optimize pure C strings initialization.
210 * lisp.h (make_pure_string): Fix prototype.
211 (build_pure_c_string): New function, defined as static inline. This
212 provides a better opportunity to optimize away calls to strlen when
213 the function is called with compile-time constant argument.
214 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
215 argument, adjust users accordingly. Use build_pure_c_string where
217 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
218 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
219 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
221 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

230 Avoid calls to strlen in path processing functions.
231 * fileio.c (file_name_as_directory): Add comment. Change to add
232 srclen argument and return the length of result. Adjust users
234 (directory_file_name): Fix comment. Change to add srclen argument,
235 swap 1st and 2nd arguments to obey the common convention. Adjust
237 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
239 2012-07-10 Glenn Morris <rgm@gnu.org>
241 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
242 Move PENDING_OUTPUT_COUNT definition to configure.
244 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
245 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
246 * s/gnu.h (DATA_START): Move definitions to configure.
248 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
249 We include usg5-4-common.h, which defines them both.
251 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
252 O_RDONLY already includes it).
254 Stop ns builds setting the EMACSLOADPATH environment variable.
255 * nsterm.m (ns_load_path): Rename from ns_init_paths.
256 Now it does not set EMACSLOADPATH, just returns the load-path string.
257 * nsterm.h: Update accordingly.
258 * lread.c [HAVE_NS]: Include nsterm.h.
259 (init_lread) [HAVE_NS]: Use ns_load_path.
260 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
262 2012-07-09 Glenn Morris <rgm@gnu.org>
264 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
265 since the included bsd-common.h does so.
267 Stop ns builds setting the EMACSPATH environment variable.
268 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
269 (ns_init_paths): Do not set EMACSPATH.
270 * nsterm.h (ns_exec_path): Add it.
271 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
274 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
276 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
278 * process.c (wait_reading_process_output): 'waitchannels' was unset
279 when read_kbd || !NILP (wait_for_cell); fix this.
281 Add GCC-style 'const' attribute to functions that can use it.
282 * character.h (char_resolve_modifier_mask):
283 * keyboard.h (make_ctrl_char):
284 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
285 (init_character_once, next_almost_prime, init_fns, init_image)
286 (flush_pending_output, init_sound):
287 * mem-limits.h (start_of_data):
288 * menu.h (finish_menu_items):

291 Declare the dummy function with ATTRIBUTE_CONST.
292 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
293 Add decls with ATTRIBUTE_CONST.
295 Minor improvements to make_formatted_string.
296 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
297 where int is good enough, as vsprintf returns an int.
298 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
300 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
302 Use make_formatted_string to avoid double length calculation.

304 * alloc.c (make_formatted_string): New function.
305 * buffer.c (Fgenerate_new_buffer_name): Use it.
306 * dbus.c (syms_of_dbusbind): Likewise.
307 * editfns.c (Fcurrent_time_zone): Likewise.
308 * filelock.c (get_boot_time): Likewise.

327 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
329 Move marker debugging code under MARKER_DEBUG.
330 * marker.c (MARKER_DEBUG): Move marker debugging code under
331 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
332 for bootstrap with --enable-checking (~3x slowdown reported
333 by Juanma Barranquero <lekktu@gmail.com>).
334 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
336 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
338 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
339 See <http://bugs.gnu.org/11825#29>.
341 2012-07-08 Eli Zaretskii <eliz@gnu.org>
343 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
344 has no font, use the frame's font. (Bug#11813)
345 (display_line): Add commentary about displaying truncation glyphs
347 (produce_special_glyphs): Move here from term.c.
349 * term.c (produce_special_glyphs): Move to xdisp.c.
351 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
354 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
356 * xdisp.c (display_line): Avoid warning about implicit declaration
359 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
361 * lisp.h: Remove empty conditional.
363 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
365 * lread.c (load_path_check): Now static.
367 Fix some minor --with-ns problems found by static checking.
368 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
369 (x_set_font) [!HAVE_X_WINDOWS]:
370 * image.c (xpm_load_image) [HAVE_NS]:
371 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
372 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
374 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
375 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
376 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
377 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
378 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
379 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
380 Fix pointer signedness problem.
381 * xfaces.c (FRAME_X_FONT_TABLE):
382 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
384 2012-07-07 Glenn Morris <rgm@gnu.org>
386 * lread.c (load_path_check): New function, split from init_lread.
387 (init_lread): Reorganize. Motivation:
388 If EMACSLOADPATH is set, check/warn about that rather than the
389 defaults, which we are not going to use. Hence we can remove
390 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
391 Don't warn if site-lisp directories are missing.
392 If not installed, start from a blank load-path, since
393 PATH_LOADSEARCH refers to the eventual installation directories.
395 2012-07-07 Eli Zaretskii <eliz@gnu.org>
397 Support truncation and continuation glyphs on GUI frames, when
398 fringes are disabled. (Bug#11832)
399 * xdisp.c (init_iterator): Get dimensions of truncation and
400 continuation glyphs even if on GUI frames. Adjust
401 it->last_visible_x on GUI frames when the left or right fringes,
403 (start_display, move_it_in_display_line_to): Handle the case of a
404 GUI frame without a fringe to display continuation or truncation
406 (insert_left_trunc_glyphs): Support GUI frames: make sure
407 truncation glyphs overwrite enough glyphs from the current line to
408 have sufficient space in pixels.
409 (display_line): Support truncation and continuation glyphs on GUI
410 frames. If some spare pixels are left on the line after inserting
411 the truncation glyphs, fill that space with a stretch glyph of a
412 suitably computed width.
414 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
415 produce_glyphs, to support GUI sessions.
417 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
419 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
421 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
423 Do not require float-time's arg to fit in time_t (Bug#11825).
424 This works better on hosts where time_t is unsigned, and where
425 float-time is applied to the (negative) difference between two times.
426 * editfns.c (decode_time_components): Last arg is now double *,
427 not int *, and means to store all the result as a double, without
428 worrying about whether the seconds part fits in time_t.
430 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
432 (Ffloat_time): Do not fail merely because the specified time falls
433 outside of time_t range.
435 2012-07-07 Glenn Morris <rgm@gnu.org>

446 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
448 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
450 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
451 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
452 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
453 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
454 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
455 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
457 * xfont.c (compare_font_names): Redo to omit the need for casts.
459 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
461 * xfns.c (Fx_change_window_property): Doc fix.
462 * w32fns.c (Fx_change_window_property): Doc fix.
464 * w32fns.c (Fx_window_property): Accept the same arguments as the
465 X Windows version. Doc fix.
466 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
468 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
469 Eli Zaretskii <eliz@gnu.org>
471 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
472 Windows-specific code from nt/config.nt moved here.
473 Obsolete settings removed.
475 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
477 * process.c: Avoid unnecessary calls to gettime.
478 (wait_reading_process_output): Don't get the time of day
479 when gobbling data immediately and not waiting, as there's no need
480 for it in that case. This removes a FIXME.
482 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
484 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
485 is defined (Bug#11768).
487 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
489 Fix marker debugging code.
490 * marker.c (byte_char_debug_check): Do not perform the check
491 if buffer is not multibyte.
492 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
493 Call byte_char_debug_check with correct arguments.
495 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
497 Compile marker debugging code only if ENABLE_CHECKING is defined.
498 * marker.c (byte_char_debug_check, count_markers):
499 Use only if ENABLE_CHECKING is defined.
500 (byte_debug_flag): Remove.
501 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
502 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
504 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
506 Avoid code repetition in marker-related functions.
507 * marker.c (attach_marker): New function.
508 (Fset_marker, set_marker_restricted, set_marker_both)
509 (set_marker_restricted_both): Use it.
510 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
511 Consistently rename charno to charpos.
512 (marker_position): Add eassert.
513 (marker_byte_position): Convert to eassert.
515 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
517 Simplify list operations in unchain_overlay and unchain_marker.

530 (save_restriction_save): Use build_marker.
531 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
532 * window.c (save_window_save): Likewise.
534 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
536 Do not use Fdelete_overlay in delete_all_overlays
537 to avoid redundant calls to unchain_overlay.
538 * buffer.c (drop_overlay): New function.
539 (delete_all_overlays, Fdelete_overlay): Use it.
540 * minibuf.c (get_minibuffer): Fix comment.
542 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
544 Port to OpenBSD 5.1 amd64.
545 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
546 This is needed for OpenBSD, and should be harmless on all BSD systems.
547 Also, include <sys/sysctl.h>, as it should be available on all
548 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
549 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
550 use p_pid member, not kp_proc.pid.
552 2012-07-06 Glenn Morris <rgm@gnu.org>
554 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
556 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
558 More xmalloc and related cleanup.
559 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
560 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
561 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

567 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
569 Omit needless casts involving void * pointers and allocation.
570 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
571 as the former is more robust if P's type is changed.
572 Prefer xzalloc to xmalloc + memset 0.
573 Simplify malloc-or-realloc to realloc.
574 Don't worry about xmalloc returning a null pointer.
575 Prefer xstrdup to xmalloc + strcpy.
576 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
578 * keyboard.c (apply_modifiers_uncached): Prefer local array to
579 alloca of a constant.
581 2012-07-05 Eli Zaretskii <eliz@gnu.org>
583 * xdisp.c (display_line): Fix horizontal pixel coordinates when
584 hscroll is larger than the line width. Fixes long and futile
585 looping inside extend_face_to_end_of_line (on a TTY) producing
586 glyphs that are not needed and thrown away.
588 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
590 * marker.c (set_marker_restricted_both): Simplify by using
593 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
595 * editfns.c (region_limit): Simplify by using clip_to_bounds.
597 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
599 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
600 not defined (Bug#11768).

604 followed by gtk_box_set_homogeneous (Bug#11768).
605 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
606 (update_theme_scrollbar_width, xg_create_scroll_bar):
607 Use gtk_scrollbar_new (Bug#11768).
608 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
609 (is_box_type): New function (Bug#11768).
610 (xg_tool_item_stale_p): Call is_box_type.
611 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
612 with default display (Bug#11768).
614 2012-07-05 Eli Zaretskii <eliz@gnu.org>
616 * xdisp.c (window_hscroll_limited): New function.
617 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
618 coordinates when window's hscroll is set to insanely large
621 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
623 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
624 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

682 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
684 * fileio.c (time_error_value): Check the right error number.
685 Problem reported by Troels Nielsen in
686 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
688 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
690 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
691 This should be fixed in a better way; see Eli Zaretskii in
692 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
693 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
695 * fileio.c (time_error_value): Rename from special_mtime.
696 The old name's problems were noted by Eli Zaretskii in
697 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
699 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
700 This variable's comment says Emacs needs at least one GDB-visible
701 symbol of type enum pvec_type, to work around GDB problems.
702 The symbol's value doesn't matter.
704 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
705 that causes compilation to fail on pre-C99 compilers.
707 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
709 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
710 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
712 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
714 * buffer.c (init_buffer_once): Fix initialization of
715 headers for buffer_defaults and buffer_local_symbols.
716 Reported by Juanma Barranquero <lekktu@gmail.com>.
718 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
720 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
721 * lisp.h (enum pvec_type): Use fewer bits.
722 (PSEUDOVECTOR_SIZE_BITS): New constant.
723 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
724 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
726 (PSEUDOVECTOR_TYPEP): New macro.
727 (TYPED_PSEUDOVECTORP): Use it.
728 * fns.c (internal_equal): Adapt code to extract pvectype.
729 * emacs.c (gdb_pvec_type): Update type.
730 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
731 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
732 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
733 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
734 (sweep_vectors): Use it. Use local var `total_bytes' instead of
735 abusing vector->header.next.nbytes.
736 (live_vector_p): Use PVEC_TYPE.
737 (mark_object): Adapt code to extract pvectype. Use switch.
739 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
741 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
742 Tighten new eassert a bit.
744 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
746 Fix compilation with --enable-gcc-warnings and -O1
748 * doprnt.c (doprnt): Change type of tem to int, initialize
749 to avoid compiler warning. Add eassert.
750 * search.c (simple_search): Initialize match_byte to avoid
751 compiler warning. Add eassert.
753 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
755 Avoid weird behavior with large horizontal scrolls.
756 Without this change, for example, large hscroll values would
757 mess up Emacs's display on Fedora 15 x86, presumably due to
758 overflows in int calculations in the display code.
759 Also, if buffers had long lines, Emacs would freeze.
760 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
761 (set_window_hscroll): New function, containing the old guts of
762 Fset_window_hscroll. Return the clipped value.
763 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
764 This avoids the need to check against PTRDIFF_MAX.
766 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
768 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
770 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
772 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
774 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
775 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
776 since GCC 4.4.6 issues a bogus warning for them.
778 Fix bugs in file timestamp newness comparisons.
779 * fileio.c (Ffile_newer_than_file_p):
780 * lread.c (Fload): Use full timestamp resolution of files,
781 not just the 1-second resolution, so that files that are only
782 slightly newer still count as newer.
783 * fileio.c (Ffile_newer_than_file_p): Don't assume file
784 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
786 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
788 * fileio.c: Improve handling of file time marker. (Bug#11852)
789 (special_mtime): New function.
790 (Finsert_file_contents, Fverify_visited_file_modtime):
791 Use it to set special mtime values consistently.
793 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
795 * fileio.c (Finsert_file_contents): Properly handle st_mtime
796 marker for non-existing file. (Bug#11852)
798 2012-07-03 Glenn Morris <rgm@gnu.org>
800 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
801 and did not make it into globals.h).
803 2012-07-03 Tom Tromey <tromey@redhat.com>

843 * lisp.h (Frandom): Make it visible to C.
844 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
845 buffer for invisible buffers. (Bug#1229)
847 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
849 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
850 values which aren't power of 2.
851 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
852 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
855 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
857 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
859 * alloc.c (mark_object): Revert part of last patch to use `switch'.
861 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
863 * alloc.c (allocate_vector_block): Remove redundant
864 calls to mallopt if DOUG_LEA_MALLOC is defined.
865 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
866 avoid calls to mallopt if zero_vector is returned.
868 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
870 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
871 is enabled, avoid dereferencing NULL current_sblock if
874 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
876 Cleanup basic buffer management.
877 * buffer.h (struct buffer): Change layout to use generic vector
878 marking code. Fix some comments. Change type of 'clip_changed'
879 to bitfield. Remove unused #ifndef old.
880 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
881 (GET_OVERLAYS_AT): Fix indentation.
882 (for_each_per_buffer_object_at): New macro.
883 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
884 (Fbuffer_local_variables): Use it.
885 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
886 * alloc.c (allocate_buffer): Adjust to match new layout of
887 struct buffer. Fix comment.
888 (mark_overlay): New function.
889 (mark_buffer): Use it. Use mark_vectorlike to mark normal
890 Lisp area of struct buffer.
891 (mark_object): Use it. Adjust marking of misc objects
892 and related comments.
894 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
896 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
897 wrapper that is not needed because the wrapped code is a no-op (zero
898 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
899 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
901 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
903 * alloc.c (mark_buffer): Simplify. Remove prototype.
904 (mark_object): Add comment. Reorganize marking of vector-like
905 objects. Use CHECK_LIVE for all vector-like objects except buffers
906 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
907 redundant calls to mark_vectorlike for bool vectors.
909 2012-06-30 Glenn Morris <rgm@gnu.org>
911 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
913 * epaths.in (PATH_SITELOADSEARCH): New.
914 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
915 This is rather than relying on --enable-locallisppath elements
916 having "site-lisp" in their names. (Bug#10208#25, 11658)
918 2012-06-30 Eli Zaretskii <eliz@gnu.org>
920 * w32proc.c (sys_select): Accept and ignore one more argument.
922 * w32.c (emacs_gnutls_pull): Call select with one more argument.
924 * sysselect.h [DOS_NT]: Don't include sys/select.h.
925 (pselect) [!MS_DOS]: Redirect to sys_select.
927 * sysdep.c: Don't include dos.h and dosfns.h.
929 * process.c (sys_select):
930 * msdos.c (sys_select): Accept one more argument and ignore it.
932 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
933 adapt data types and code to that.
936 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
937 which clashes with the gnulib function of the same name.
939 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
941 * font.c (font_style_to_value, font_style_symbolic)
942 (font_prop_validate_style): Add type checks for values in
945 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
947 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
950 2012-06-29 Eli Zaretskii <eliz@gnu.org>
952 * xdisp.c (try_window_id): Undo last change.
954 * w32.c (getwd): Adjust commentary about startup_dir.
955 (init_environment): Always call sys_access, even in non-MSVC
956 builds. Don't chdir to the directory of the Emacs executable.
957 This undoes code from 1997 which was justified by the need to
958 "avoid conflicts when removing and renaming directories". But its
959 downside was that every relative file name was being interpreted
960 relative to the directory of the Emacs executable, which can never
961 be TRT. In particular, it broke sys_access when called with
963 (sys_access): Map GetLastError to errno.
965 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
967 * window.h (struct window): Change type of 'fringes_outside_margins'
968 to bitfield. Fix comment. Adjust users accordingly.
969 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
971 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
974 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
976 * gnutls.c (emacs_gnutls_handshake):
977 Add QUIT to make the loop interruptible.

1157 Use sprintf return value instead of invoking strlen on result.
1158 In the old days this wasn't portable, since some sprintf
1159 implementations returned char *. But they died out years ago and
1160 Emacs already assumes sprintf returns int.
1161 Similarly for float_to_string.

1170 Use sprintf or float_to_string result to avoid need to call strlen.
1171 * data.c (Fnumber_to_string):
1172 Use make_unibyte_string, since the string must be ASCII.
1173 * lisp.h, print.c (float_to_string): Now returns int length.
1174 * term.c (produce_glyphless_glyph):
1175 Use sprintf result rather than recomputing it.
1177 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1178 * Makefile.in (ALL_CFLAGS):
1179 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

1208 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1210 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

1213 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1215 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1216 instead of truncating it to 63 (admittedly a generous limit).

1276 * keyboard.c (kbd_buffer_get_event):
1277 * process.c (Faccept_process_output):
1278 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1279 This improves on the previous patch, which introduced a bug
1280 when time_t is unsigned and as wide as intmax_t.
1281 See <http://bugs.gnu.org/9000#51>.
1283 2012-06-23 Eli Zaretskii <eliz@gnu.org>

1346 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1348 Support higher-resolution time stamps (Bug#9000).
1349 The time stamps are only nanosecond-resolution at the C level,
1350 since that's the best that any real-world system supports now.
1351 But they are picosecond-resolution at the Lisp level, as that's
1352 easy, and leaves room for future OS improvements.
1354 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1357 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1358 Don't get current time unless it's needed.
1360 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1361 now provides it if it's absent.
1362 (start_atimer): Port to higher-res time stamps.
1363 Check for time stamp overflow. Don't get current time more
1364 often than is needed.
1366 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1367 Include systime.h, not time.h.
1368 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1370 * dired.c: Include stat-time.h.
1371 (Ffile-attributes): File times now have higher resolution.

1374 (struct image): Timestamp now has higher resolution.
1376 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1377 has at least microseconds now. All uses removed.
1378 (update_frame, update_single_window, update_window, update_frame_1)
1379 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1381 * editfns.c (time_overflow): Now extern.
1382 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1383 (float-time, Fformat_time_string, Fcurrent_time_string)
1384 (Fcurrent_time_zone): Accept and generate higher-resolution

1387 (decode_time_components, lisp_seconds_argument): New functions.
1388 (make_time): Now static.
1389 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1390 Report an error if the time is invalid, rather than having the caller
1393 * fileio.c: Include <stat-time.h>
1394 (Fcopy_file): Copy higher-resolution time stamps.
1395 Prefer to set the time stamp via a file descriptor if that works.
1396 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1397 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1398 (Fvisited_file_modtime, Fset_visited_file_modtime):
1399 Support higher-resolution time stamps.
1401 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1403 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1405 * image.c (prepare_image_for_display, clear_image_cache)
1406 (lookup_image): Port to higer-resolution time stamps.
1408 * keyboard.c (start_polling, bind_polling_period):
1409 Check for time stamp overflow.
1410 (read_char, kbd_buffer_get_event, timer_start_idle)
1411 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1412 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1413 Port to higher-resolution time stamps. Do not assume time_t is signed.
1414 (decode_timer): New function. Timers are now vectors of length 9,
1415 not 8, to accommodate the picosecond component.
1416 (timer_check_2): Use it.
1418 * nsterm.m (select_timeout, timeval_subtract): Remove.
1419 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1420 as they're a bit more accurate and handle overflow better.
1421 (ns_select): Change prototype to be compatible with pselect.
1422 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1423 * nsterm.h (ns_select): Adjust prototype.
1425 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1426 us-resolution time stamps.
1427 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1429 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1431 * lisp.h (time_overflow): New decl.
1432 (wait_reading_process_output): First arg is now intmax_t, not int,
1433 to accommodate larger waits.
1435 * process.h (struct Lisp_Process.read_output_delay):
1436 Now counts nanoseconds, not microseconds.
1437 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1439 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1440 (wait_reading_process_output):
1441 Port to ns-resolution time stamps.
1442 (Faccept_process_output, wait_reading_process_output):
1443 Check for time stamp overflow. Do not assume time_t is signed.
1444 (select_wrapper): Remove; we now use pselect.
1445 (Fprocess_attributes): Now generates ns-resolution time stamps.
1447 * sysdep.c: Include utimens.h. Don't include utime.h
1448 or worry about struct utimbuf; gnulib does that for us now.
1449 (gettimeofday): Remove; gnulib provides a substitute.
1450 (make_timeval): New function.
1451 (set_file_times): Now sets ns-resolution time stamps.
1452 New arg FD; all uses changed.
1453 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1454 (system_process_attributes):
1455 Now returns ns-resolution time stamp. All uses changed.
1456 Check for time stamp overflow.
1458 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1459 provides a substitute now.
1461 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1462 since it guarantees struct timespec.
1463 (EMACS_TIME): Now struct timespec, so that we can support
1464 ns-resolution time stamps.
1465 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1466 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1467 (EMACS_USECS): Remove.
1468 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,

1479 (make_timeval, make_lisp_time, decode_time_components): New decls.
1480 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

1575 gets killed during executing of this function (Bug#11665).

1578 run by this hook should not change the current buffer.

1935 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
1936 (init_alloc_once): Add call to init_vectors.
1938 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
1940 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
1942 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
1944 * doprnt.c (doprnt): Truncate multibyte char correctly.
1945 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
1946 would mishandle a string argument "Xc" if X was a multibyte
1947 character of length 2: it would truncate after X's first byte
1948 rather than including all of X.
1950 2012-06-06 Chong Yidong <cyd@gnu.org>
1952 * buffer.c (word_wrap): Doc fix.
1954 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

1966 binary via PaX flags if the paxctl utility is available.
1967 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1968 Restore PaX flags to their default. (Bug#11398)

1972 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
1975 2012-06-03 Chong Yidong <cyd@gnu.org>
1977 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
1978 (note_mode_line_or_margin_highlight): If there is no help echo,
1979 use mode-line-default-help-echo. Handle the case where the mouse
1980 position is past the end of the mode line string.
1982 * buffer.c (buffer_local_value_1): New function, split from
1983 Fbuffer_local_value; can return Qunbound.
1984 (Fbuffer_local_value): Use it.
1985 (Vmode_line_format): Docstring tweaks.
1987 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
1989 * sysdep.c (system_process_attributes): Improve comment.
1991 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
1993 * keyboard.c: Export real-this-command to Elisp.
1994 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
1995 and DEFVAR it. Update all users.
1997 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
1999 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2001 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2002 Convert pctcpu and pctmem to Lisp float properly.
2003 Let the compiler fold better, as 100.0/0x8000 is exact.
2005 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2007 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2010 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2012 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2014 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2016 For a 'struct window', replace some Lisp_Object fields to
2017 bitfields where appropriate, remove unused fields.
2018 * window.h (struct window): Remove unused 'last_mark_x' and
2019 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2020 change it's type from Lisp_Object to bitfield.
2021 Change type of 'force_start', 'optional_new_start',
2022 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2023 fields from Lisp_Object to bitfield. Adjust users accordingly.
2025 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2027 Pacify gcc -Wdouble-precision when using Xaw.
2028 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2029 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2030 Use 'float' consistently, rather than 'float' in most places
2031 and 'double' in a couple of places.
2033 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2035 * xdisp.c (handle_stop): Detect whether we have overlay strings
2036 loaded by testing it->current.overlay_string_index to be
2037 non-negative, instead of checking whether n_overlay_strings is
2038 positive. (Bug#11587)
2040 2012-05-31 Chong Yidong <cyd@gnu.org>
2042 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2044 * doc.c (Fsubstitute_command_keys): Doc fix.
2046 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2048 * search.c (search_buffer): Remove calls to
2049 r_alloc_inhibit_buffer_relocation, as it is now called by
2050 maybe_unify_char, which was the cause of relocation of buffer text
2053 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2055 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2056 for the duration of call to load_charset, to avoid problems with
2057 callers of maybe_unify_char that access buffer text through C
2060 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2061 decrement the inhibition flag, instead of just setting or
2064 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2066 Remove obsolete '#define static' cruft.
2067 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2068 This #undef was "temporary" in 2000; it is no longer needed
2069 now that '#define static' has gone away.
2070 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2071 (gray_bitmap_bits): Remove; no longer needed.
2072 All uses replaced with definiens.
2073 * xterm.c: Include "bitmaps/gray.xbm".
2075 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2077 Clean up __executable_start, monstartup when --enable-profiling.
2078 The following changes affect the code only when profiling.
2079 * dispnew.c (__executable_start): Rename from safe_bcopy.
2080 Define only on platforms that need it.
2081 * emacs.c: Include <sys/gmon.h> when profiling.
2082 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2083 (__executable_start): Remove decl, since lisp.h does it now.
2084 (safe_bcopy): Remove decl; no longer has that name.
2085 (main): Coalesce #if into single bit of code, for simplicity.
2086 Cast pointers to uintptr_t, since standard libraries want integers
2088 * lisp.h (__executable_start): New decl.
2090 2012-05-31 Glenn Morris <rgm@gnu.org>
2092 * image.c (Fimagemagick_types): Doc fix.
2094 2012-05-30 Jim Meyering <meyering@redhat.com>
2096 * callproc.c (Fcall_process_region): Include directory component
2097 in mkstemp error message (Bug#11586).
2099 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2101 * alloc.c, lisp.h (make_pure_vector): Now static.
2103 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

2106 Move to byte-run.el.
2107 (Fautoload): Do the hash-doc more carefully.
2108 * data.c (Fdefalias): Purify definition, except for keymaps.
2109 (Qdefun): Move from eval.c.
2110 * lisp.h (Qdefun): Remove.
2111 * lread.c (read1): Tiny simplification.
2113 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2115 Do not create empty overlays with the evaporate property (Bug#9642).
2116 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2117 Bug#9642, but explicitly check that the buffer the overlay would
2118 be moved to is live and rearrange lines to make sure that errors
2119 will not put the overlay in an inconsistent state.
2120 (Fdelete_overlay): Cosmetics.
2122 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2124 * w32term.c (my_bring_window_to_top): New function.
2125 (x_raise_frame): Use handle returned by DeferWindowPos, which
2126 could be different from the original one.
2127 Call my_bring_window_to_top instead of my_set_foreground_window.
2130 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2131 by calling BringWindowToTop.
2133 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
2134 (WM_EMACS_END): Increase by one.
2136 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2138 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2139 This avoids undefined behavior that might cause the eassert
2140 to not catch an out-of-range value.
2142 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2144 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2145 Update dependencies.
2147 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2149 * bidi.c (bidi_mirror_char): Fix last change.
2151 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
2153 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
2154 when referring to sectname field in printf format.
2156 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2158 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2159 Only r_alloc_inhibit_buffer_relocation needed to be added;
2160 the others were already declared.
2162 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2163 before checking whether it's out of range. Put the check inside
2165 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2167 2012-05-27 Ken Brown <kbrown@cornell.edu>
2169 * callproc.c (Fcall_process): Restore a line that was accidentally
2170 commented out in the 2011-02-13 change (bug#11547).
2172 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2174 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2175 defined on ralloc.c.
2177 * buffer.c [REL_ALLOC]: Remove prototypes of
2178 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2179 they are now on lisp.h.
2181 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2183 * search.c (search_buffer): Use it to inhibit relocation of buffer
2184 text while re_search_2 is doing its job, because re_search_2 is
2185 passed C pointers to buffer text. (Bug#11519)
2187 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2190 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2191 state after an additional call to move_it_in_display_line_to, keep
2192 the values of it->max_ascent and it->max_descent found for the
2194 (pos_visible_p): Revert the comparison against bottom_y to what it
2195 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2198 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2200 Fix coding-related core dumps with gcc -ftrapv.
2201 The code was computing A - B, where A and B are pointers, and B is
2202 random garbage. This can lead to core dumps on platforms that
2203 have special pointer registers, and it also leads to core dumps on
2204 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2205 A - B only when B is initialized properly.
2206 * coding.c (coding_set_source, coding_set_destination): Return void.
2207 (coding_change_source, coding_change_destinations): New functions,
2208 with the old behaviors of coding_set_source and coding_set_destination.
2209 All callers that need an offset changed to use these new functions.
2211 2012-05-26 Glenn Morris <rgm@gnu.org>
2213 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2215 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2217 Extend mouse support on W32 text-mode console.
2218 * xdisp.c (draw_row_with_mouse_face):
2219 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2221 * w32console.c: Include window.h.
2222 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2224 (initialize_w32_display): Initialize mouse-highlight data.
2226 * w32inevt.c: Include termchar.h and window.h.
2227 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2228 moves, call note_mouse_highlight. If help_echo changed, call
2229 gen_help_event to produce help-echo message in the echo area.
2230 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2233 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2235 * lread.c (read1): Simplify slightly to avoid an overflow warning
2236 with GCC 4.7.0 on x86-64.
2238 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2240 * bidi.c (bidi_mirror_char): Revert last change: an int is
2241 definitely wide enough here.
2243 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2245 Fix integer width and related bugs (Bug#9874).
2246 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
2247 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
2248 (string_bytes, check_sblock, allocate_string_data):
2249 (compact_small_strings, Fmake_bool_vector, make_string)
2250 (make_unibyte_string, make_multibyte_string)
2251 (make_string_from_bytes, make_specified_string)
2252 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
2253 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2255 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2256 (allocate_pseudovector):
2257 Use int, not EMACS_INT, where int is wide enough.
2258 (inhibit_garbage_collection, Fgarbage_collect):
2259 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2260 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2261 int might not be wide enough.
2262 (bidi_cache_search, bidi_cache_find, bidi_init_it)
2263 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2264 (bidi_at_paragraph_end, bidi_find_paragraph_start)
2265 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2266 (bidi_level_of_next_char, bidi_move_to_visually_next):
2267 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2268 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2269 (Fkill_buffer, Fset_buffer_major_mode)
2270 (advance_to_char_boundary, Fbuffer_swap_text)
2271 (Fset_buffer_multibyte, overlays_at, overlays_in)
2272 (overlay_touches_p, struct sortvec, record_overlay_string)
2273 (overlay_strings, recenter_overlay_lists)
2274 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2275 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
2276 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2277 (Foverlay_recenter, last_overlay_modification_hooks_used)
2278 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2279 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2280 (validate_region): Omit unnecessary test for b <= e,
2281 since that's guaranteed by the previous test.
2282 (adjust_overlays_for_delete): Avoid pos + length overflow.
2283 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2284 (report_overlay_modification):
2285 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2286 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2287 Omit pointer cast, which isn't needed anyway, and doesn't work
2288 after the EMACS_INT -> ptrdiff_t change.
2289 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2290 * buffer.h: Adjust decls to match defn changes elsewhere.
2291 (struct buffer_text, struct buffer):
2292 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2293 Use EMACS_INT, not int, where int might not be wide enough.
2294 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
2295 not int, to avoid needless 32-bit limit on 64-bit hosts.
2296 (exec_byte_code): Use tighter memory-full test, one that checks
2297 for alloca overflow. Don't compute the address of the object just
2298 before an array, as that's not portable. Use EMACS_INT, not
2299 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2300 * callint.c (Fcall_interactively):
2301 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2302 * callproc.c (call_process_kill, Fcall_process):
2303 Don't assume pid_t fits into an Emacs fixnum.
2304 (call_process_cleanup, Fcall_process, child_setup):
2305 Don't assume pid_t fits into int.
2306 (call_process_cleanup, Fcall_process, delete_temp_file)
2307 (Fcall_process_region):
2308 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2309 (Fcall_process): Simplify handling of volatile integers.
2310 Use int, not EMACS_INT, where int will do.
2311 * casefiddle.c (casify_object, casify_region, operate_on_word)
2312 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2313 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2314 (casify_object): Avoid integer overflow when overallocating buffer.
2315 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2316 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2317 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2318 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2319 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2320 integers are now checked earlier. All uses replaced with XINT.
2322 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2323 For CCL_MapSingle, check that content and value are in int range.
2324 (ccl_driver, Fregister_code_conversion_map):
2325 Check that Vcode_version_map_vector is a vector.
2326 (resolve_symbol_ccl_program): Check that vector header is in range.
2327 Always copy the vector, so that we can check its contents reliably
2328 now rather than having to recheck each instruction as it's being
2329 executed. Check that vector words fit in 'int'.
2330 (ccl_get_compiled_code, Fregister_ccl_program)
2331 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2332 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2333 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2334 contents are in range.
2335 (Fccl_execute_on_string): Check that status is in range.
2336 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2337 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2338 Accept and return EMACS_INT, not int, because callers can pass values
2340 (c_string_width, strwidth, lisp_string_width, chars_in_text)
2341 (multibyte_chars_in_text, parse_str_as_multibyte)
2342 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
2343 (str_as_unibyte, str_to_unibyte, string_count_byte8)
2344 (string_escape_byte8, Fget_byte):
2345 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2346 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2347 avoid mishandling large integers.
2348 * character.h: Adjust decls to match defn changes elsewhere.
2349 * charset.c (load_charset_map_from_file, find_charsets_in_text)
2350 (Ffind_charset_region):
2351 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2352 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
2353 (load_charset_map_from_vector, Fdefine_charset_internal):
2354 Don't assume fixnum fits in int.
2355 (load_charset_map_from_vector, Fmap_charset_chars):
2356 Remove now-unnecessary CHECK_NATNUMs.
2357 (Fdefine_charset_internal): Check ranges here, more carefully.
2358 Don't rely on undefined behavior with signed left shift overflow.
2359 Don't assume unsigned int fits into fixnum, or that fixnum fits
2360 into unsigned int. Don't require max_code to be a valid fixnum;
2361 that's not true for gb10830 4-byte on a 32-bit host. Allow
2362 invalid_code to be a cons, for the same reason. Require code_offset
2363 to be a character. Avoid int overflow if max_char is close
2365 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2366 this is intended anyway and avoids some undefined behavior.
2367 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2368 INDEX_TO_CODE_POINT, as that's what it expects.
2369 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2370 * charset.h (DECODE_CHAR): Return int, not unsigned;
2371 this is what was intended anyway, and it avoids undefined behavior.
2372 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2373 integer-overflow issues.
2374 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.

3084 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3085 (BITS_PER_EMACS_INT): New constants, replacing
3086 what used to be in config.h, but not useful in #if.
3087 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3088 define them any more.
3089 (VAL_MAX): New macro.
3091 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3092 BITS_PER_EMACS_INT, in #if.
3093 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3094 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3095 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3096 * s/ms-w32.h (DATA_START):
3097 Move here from removed file m/intel386.h.
3098 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3099 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3101 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3103 Assume C89 or later.
3104 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
3105 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
3107 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
3108 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
3109 * textprop.c, tparam.c (NULL): Remove.
3110 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
3111 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3112 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3113 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3114 * xterm.c (input_signal_count): Assume volatile works.
3116 2012-05-21 Ken Brown <kbrown@cornell.edu>
3118 * xgselect.c (xg_select): Fix first argument in call to 'select'
3121 2012-05-20 Ken Brown <kbrown@cornell.edu>
3123 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3124 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3126 2012-05-19 Ken Brown <kbrown@cornell.edu>
3128 * xfns.c (x_in_use): Remove `static' qualifier.
3129 * xterm.h (x_in_use): Declare.
3130 * xgselect.c: Include xterm.h.
3131 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3132 and `display_arg' (bug#9754).
3134 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3136 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3138 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3139 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3141 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3143 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3145 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3146 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3148 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3149 reference to image_cache->refcount.
3150 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3152 2012-05-17 Juri Linkov <juri@jurta.org>
3154 * search.c (Fword_search_regexp, Fword_search_backward)
3155 (Fword_search_forward, Fword_search_backward_lax)
3156 (Fword_search_forward_lax): Move functions to isearch.el
3157 (bug#10145, bug#11381).
3159 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3161 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3163 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3165 * lread.c (init_obarray): Declare Qt and Qnil as special.
3167 2012-05-14 Glenn Morris <rgm@gnu.org>
3169 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3170 Put "libexec" before "bin", for the sake of init_callproc_1.
3172 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3174 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3176 * unexaix.c: Port to more-recent AIX compilers.
3177 (report_error, report_error_1, make_hdr, copy_sym)
3178 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3179 Make arguments const char *, not char *, to avoid violations of C
3180 standard and to fix some AIX warnings reported by Gilles Pion.
3182 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3184 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3185 already have overlays loaded.
3186 (handle_single_display_spec): Before returning without displaying
3187 fringe bitmap, synchronize the bidi iterator with the main display
3188 iterator, by calling iterate_out_of_display_property.
3189 (iterate_out_of_display_property): Detect buffer iteration by
3190 testing that it->string is a Lisp string.
3191 (get_next_display_element): When the current object is exhausted,
3192 and there's something on it->stack, call set_iterator_to_next to
3193 proceed with what's on the stack, instead of returning zero.
3194 (set_iterator_to_next): If called at the end of a Lisp string,
3195 proceed to consider_string_end without incrementing string
3196 position. Don't increment display vector index past the end of
3197 the display vector. (Bug#11417)
3198 (pos_visible_p): Don't report a position visible when move_it_to
3199 stopped at the last line of window, which happens to be scanned
3200 backwards by the bidi iteration. (Bug#11464)
3202 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3204 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3205 and right-margin display specs even if the spec is invalid or we
3206 are on a TTY, and thus unable to display on the fringes.
3207 That's because the text with the property will not be displayed anyway,
3208 so we need to signal to the caller that this is a "replacing"
3209 display spec. This fixes display when the spec is invalid or we
3212 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3214 * unexaix.c (make_hdr): Fix typo in prototype.
3215 This bug broke the build on AIX. Problem reported by Gilles Pion.
3217 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3219 * keyboard.c (kbd_buffer_get_event): Read special events also in
3220 batch mode. (Bug#11415)
3222 2012-05-12 Glenn Morris <rgm@gnu.org>
3224 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3226 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3228 * lisp.mk (lisp): Add newcomment.elc.
3230 2012-05-12 Glenn Morris <rgm@gnu.org>
3232 * Makefile.in (MKDIR_P): New, set by configure.
3233 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3235 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3237 Remove unused function hourglass_started.
3238 * dispextern.h (hourglass_started):
3239 * w32fns.c (hourglass_started):
3240 * xdisp.c (hourglass_started): Remove.
3242 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3244 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3245 Update dependencies.
3247 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3249 * xgselect.c (xg_select): Put maxfds+1 into a var.
3250 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3252 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3254 2012-05-10 Dave Abrahams <dave@boostpro.com>
3256 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3257 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3259 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3261 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3262 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3263 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3264 Initialize xd_registered_buses.
3266 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3268 Untag more efficiently if USE_LSB_TAG.
3269 This is based on a proposal by YAMAMOTO Mitsuharu in
3270 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3271 For an admittedly artificial (nth 8000 longlist) benchmark on
3272 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3273 Emacs's overall text size by 1%.
3274 * lisp.h (XUNTAG): New macro.
3275 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3276 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3277 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3278 * eval.c (Fautoload):
3279 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3280 * frame.h (XFRAME): Use XUNTAG.
3282 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3283 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3284 Remove unportable assumptions about print widths of types like
3286 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3287 intptr_t when converting between pointer and integer, to avoid GCC
3288 warnings about wrong width.
3290 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3292 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3293 stack for each reader_thread, instead of defaulting to 8MB
3294 determined by the linker. This avoids failures in creating
3295 subprocesses on Windows 7, see the discussion in this thread:
3296 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3298 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3300 Fix up display of the *Minibuf-0* buffer in the mini window.
3301 * keyboard.c (read_char): Don't clear the echo area if there's no
3303 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3304 contents of *Minibuf-0*) if there's no message displayed in its stead.
3306 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3308 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3311 2012-05-06 Chong Yidong <cyd@gnu.org>
3313 * lisp.mk (lisp): Update.
3315 2012-05-05 Jim Meyering <meyering@redhat.com>
3317 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3319 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3321 * data.c (PUT_ERROR): New macro.
3322 (syms_of_data): Use it. Add new error type `user-error'.
3323 * undo.c (user_error): New function.
3324 (Fprimitive_undo): Use it.
3325 * print.c (print_error_message): Adjust print style for `user-error'.
3326 * keyboard.c (user_error): New function.
3327 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3329 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3331 Do not limit current-time-string to years 1000..9999.
3332 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3333 (Fcurrent_time_string): Support any year that is supported by the
3334 underlying localtime representation. Don't use asctime, as it
3335 has undefined behavior for years outside the range -999..9999.
3337 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3339 Fix race conditions involving setenv, gmtime, localtime, asctime.
3340 Without this fix, interrupts could mess up code that uses these
3341 nonreentrant functions, since setting TZ invalidates existing
3342 tm_zone or tzname values, and since most of these functions return
3343 pointers to static storage.
3344 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3345 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3346 Grow the critical sections to include not just invoking
3347 localtime/gmtime, but also accessing these functions' results
3348 including their tm_zone values if any, and any related TZ setting.
3349 (format_time_string): Last arg is now struct tm *, not struct tm **,
3350 so that the struct tm is saved in the critical section.
3351 All callers changed. Simplify allocation of initial buffer, partly
3352 motivated by the fact that memory allocation needs to be outside
3353 the critical section.
3355 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3357 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3358 with RESET_INTERVAL.
3360 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3361 Remove duplicated buffer name initialization.
3363 2012-05-02 Jim Meyering <jim@meyering.net>
3365 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3367 * xfns.c (x_window): Use xstrdup (Bug#11375).
3369 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3371 * xdisp.c (pos_visible_p): If already at a newline from the
3372 display string before the 'while' loop, don't walk back the glyphs
3373 from it3.glyph_row. Solves assertion violation when the display
3374 string begins with a newline (egg.el). (Bug#11367)
3376 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3378 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3381 2012-05-01 Glenn Morris <rgm@gnu.org>
3383 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3384 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3385 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3386 All were removed before 23.1.
3388 * dispnew.c: Remove HAVE_LIBNCURSES test;
3389 it is always true on relevant platforms.
3391 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3392 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3394 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3396 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3398 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3399 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3402 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3404 Do not avoid creating empty evaporating overlays (Bug#9642).
3405 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3406 That is, do not delete an evaporating overlay if it becomes
3407 empty after its bounds are adjusted to fit within its buffer.
3408 This fix caused other problems, and I'm reverting it until we get
3409 to the bottom of them.
3411 2012-04-27 Chong Yidong <cyd@gnu.org>
3413 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3415 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3417 * xdisp.c (pos_visible_p): If the window start position is beyond
3418 ZV, start the display from buffer beginning. Prevents assertion
3419 violation in init_iterator when the minibuffer window is scrolled
3422 * window.c (window_scroll_pixel_based): Likewise.
3424 2012-04-27 Chong Yidong <cyd@gnu.org>
3426 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3428 2012-04-27 Glenn Morris <rgm@gnu.org>
3430 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3431 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3433 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3435 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3436 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3438 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3440 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3441 display element, check also the underlying string or buffer
3442 character. (Bug#11341)
3444 * w32menu.c: Include w32heap.h.
3445 (add_menu_item): If the call to AppendMenuW (via
3446 unicode_append_menu) fails, disable Unicode menus only if we are
3447 running on Windows 9X/Me.
3449 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3451 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3452 (xgetint): Add missing shift for LSB tags.
3454 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3456 * keyboard.c (read_char): Don't wipe echo area for select window
3457 events: These might get delayed via `mouse-autoselect-window'
3460 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3462 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3463 manipulation of :loaded-from data.
3465 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3467 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3468 now a cons (bug#11311).
3470 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3472 Do not create empty overlays with the evaporate property (Bug#9642).
3473 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3474 if it becomes empty after its bounds are adjusted to fit within
3475 its buffer. Without this fix, in a nonempty buffer (let ((o
3476 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3477 yields an empty overlay that has the evaporate property, which is
3478 not supposed to happen.
3480 Fix minor GTK3 problems found by static checking.
3481 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3482 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3483 (struct _EmacsFixedClass, emacs_fixed_get_type):
3484 Move decls here from emacsgtkfixed.h, since they needn't be public.
3485 (emacs_fixed_get_type): Now static.
3486 (emacs_fixed_class_init): Omit unused local.
3487 (emacs_fixed_child_type): Remove; unused.

3489 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3490 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
3491 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3492 (EMACS_FIXED_GET_CLASS): Remove; unused.
3493 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
3495 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
3496 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3498 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3500 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3501 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3502 (__malloc_size_t, __malloc_ptrdiff_t):
3503 Remove. All uses removed, replaced by the definiens if needed,
3504 since we can assume C89 or better now.
3505 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
3506 (protect_malloc_state, align, get_contiguous_space)
3507 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

3513 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
3514 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3515 Define using prototypes, not old style.
3516 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3517 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
3518 (align): Don't assume that signed integer overflow wraps around.
3519 Omit unused local var.
3520 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
3521 (_free_internal_nolock, memalign, mallochook, reallochook):
3522 Omit no-longer-needed casts.
3523 (valloc): Use getpagesize, not __getpagesize.
3524 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
3525 (struct hdr): The 'magic' member is now size_t, not unsigned long.
3527 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
3529 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
3531 Move functions from C to Lisp. Make non-blocking method calls
3532 the default. Implement further D-Bus standard interfaces.
3534 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
3535 (QCdbus_request_name_allow_replacement)

3578 Do not assume ptrdiff_t is the same width as 'int'.
3580 * alloc.c: Handle unusual debugging option combinations.
3581 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
3582 since the two debugging options are incompatible.
3583 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
3585 (mem_init, mem_insert, mem_insert_fixup):
3586 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

3616 * print.c (print_preprocess): Only check print_depth if print-circle
3618 (print_object): Check for cycles even when print-circle is nil and
3619 print-gensym is t, but only check print_depth if print-circle is nil.
3621 2012-04-20 Chong Yidong <cyd@gnu.org>
3623 * process.c (wait_reading_process_output): If EIO occurs on a pty,

3679 New extern decls, to avoid calling undeclared functions.
3680 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3681 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3682 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

3723 Remove definition of GC_MARK_STACK, since the default now works.
3724 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3725 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3726 no longer the default.
3727 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3729 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

3752 2012-04-11 Daniel Colascione <dancol@dancol.org>
3754 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3755 against is gone. It's better to use vfork now so that when Cygwin
3756 gains a new, working vfork, we use it automatically (bug#10398).
3758 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

3779 being loaded (bug#10424).
3781 2012-04-09 Glenn Morris <rgm@gnu.org>
3783 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3784 not just in the obarray, before snarfing them. (Bug#11036)

3811 * minibuf.c (Fread_variable): Callers changed.
3813 2012-04-09 Eli Zaretskii <eliz@gnu.org>
3815 * xdisp.c (set_cursor_from_row): If the display string appears in
3816 the buffer at position that is closer to point than the position
3817 after the display string, display the cursor on the first glyph of
3818 the display string. Fixes cursor display when a 'display' text
3819 property immediately follows invisible text. (Bug#11094)
3821 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
3823 composite.c: use 'double' consistently
3824 * composite.c (get_composition_id): Use 'double' consistently
3825 instead of converting 'float' to 'double' and vice versa; this is
3826 easier to understand and avoids a GCC warning.
3828 2012-04-09 Glenn Morris <rgm@gnu.org>
3830 * Makefile.in: Generate leim-list with bootstrap-emacs, in
3831 preparation for dumping it with emacs. (Bug#4789)

3853 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
3854 (mark_memory): Mark Lisp_Objects only if pointers might hide in

3873 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
3874 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
3875 [!WINDOWSNT]: New macros.
3876 (init_libxml2_functions, libxml2_loaded_p): New functions.
3877 (parse_region): Call fn_xmlCheckVersion instead of using the macro
3878 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
3879 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
3880 Calls xmlCleanupParser only if libxml2 was loaded (or statically
3882 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
3883 Call init_libxml2_functions before calling libxml2 functions.
3884 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
3886 * emacs.c: Don't include libxml/parser.h.

3888 xmlCleanupParser directly.
3890 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
3892 2012-04-07 Eli Zaretskii <eliz@gnu.org>

3900 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
3901 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3902 about subtle differences between FETCH_CHAR* and STRING_CHAR*
3903 macros related to unification of CJK characters. For the details,
3904 see the discussion following the message here:
3905 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
3907 2012-04-04 Chong Yidong <cyd@gnu.org>
3909 * keyboard.c (Vdelayed_warnings_list): Doc fix.
3911 2012-04-01 Eli Zaretskii <eliz@gnu.org>
3913 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

3921 2012-03-31 Eli Zaretskii <eliz@gnu.org>
3923 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
3924 position we get to after a call to move_it_to fails the
3925 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
3926 only if we wind up in a string from display property. (Bug#11063)
3928 * window.c (Fdelete_other_windows_internal): Invalidate the row
3929 and column information about mouse highlight, so that redisplay
3930 restores it after reallocating the glyph matrices. (Bug#7464)
3932 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
3933 string comes from a `display' text property, use the buffer
3934 position of that property as if we actually saw that position in
3936 (move_it_by_lines): Remove the assertion that
3937 "it->current_x == 0 && it->hpos == 0" which can be legitimately
3938 violated when there's a before-string at the beginning of a line.
3941 2012-03-30 Eli Zaretskii <eliz@gnu.org>
3943 * xdisp.c (append_space_for_newline): If the default face was
3944 remapped, use the remapped face for the appended newline.
3945 (extend_face_to_end_of_line): Use the remapped default face for
3946 extending the face to the end of the line.
3947 (display_line): Call extend_face_to_end_of_line when the default
3948 face was remapped. (Bug#11068)
3950 2012-03-29 Eli Zaretskii <eliz@gnu.org>
3952 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

3972 handle-select-window too (Bug#8996).
3974 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
3976 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

3980 * dispextern.h (struct glyph): Change the bit length of
3981 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
3983 2012-03-24 Eli Zaretskii <eliz@gnu.org>
3985 * s/ms-w32.h (tzname): Include time.h before redirecting to
3986 _tzname. Fixes the MSVC build. (Bug#9960)

3990 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
3993 * xterm.c (XTread_socket): Only modify handling_signal if
3994 !SYNC_INPUT. (Bug#11080)
3996 2012-03-23 Eli Zaretskii <eliz@gnu.org>
3998 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
3999 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4000 when fetching a multibyte character consumes more bytes than
4001 CHAR_BYTES returns, due to unification of CJK characters in
4002 string_char. (Bug#11073)

4028 2012-03-20 Chong Yidong <cyd@gnu.org>
4030 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4031 to reflect default non-nil value of redisplay-dont-pause.
4033 2012-03-19 Kenichi Handa <handa@m17n.org>
4035 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4036 it fit in a valid range (Bug#11003).
4038 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4040 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4041 that is not from display property, accept the row as a "cursor
4042 row" if one of the string's character has a non-nil `cursor'
4043 property. Fixes cursor positioning when there are newlines in
4044 overlay strings, e.g. in icomplete.el. (Bug#11035)
4046 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

4077 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4080 2012-03-03 Glenn Morris <rgm@gnu.org>
4082 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

4100 push_it before setting up the iterator for the first overlay
4101 string, even if we have an empty string loaded.
4102 (next_overlay_string): If there's an empty string on the iterator
4103 stack, pop the stack. (Bug#10903)
4105 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4107 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4108 Suggested by Stefan Monnier in
4109 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4110 * alloc.c (widen_to_Lisp_Object): New static function.
4111 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4112 and widening them to Lisp_Objects. This would work even if
4113 USE_LSB_TAG is defined and wide integers are used, which might
4114 happen in a future version of Emacs.
4116 2012-02-25 Chong Yidong <cyd@gnu.org>
4118 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

4134 (unwind_create_frame_1): New helper function.
4136 * window.c (inhibit_window_configuration_change_hook): New var.
4137 (run_window_configuration_change_hook): Obey it.
4138 (syms_of_window): Initialize it.
4140 2012-02-22 Chong Yidong <cyd@gnu.org>
4142 * xterm.c (x_draw_image_relief): Add missing type check for

4154 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4155 when computing $valmask.
4157 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4158 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4159 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4160 It's useless in that case, and it can cause problems on hosts
4161 that allocate halves of EMACS_INT values separately.
4162 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4163 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4164 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4165 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4166 it avoids undefined behavior on hosts where shifting right by more
4167 than the word width has undefined behavior.
4169 2012-02-19 Chong Yidong <cyd@gnu.org>
4171 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4172 (Funhandled_file_name_directory, Ffile_name_as_directory)

4191 2012-02-15 Chong Yidong <cyd@gnu.org>
4193 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4194 marked as special. Also, starting docstrings with * is obsolete.
4196 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

4211 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4212 as that creates a dangerous corner case.
4214 * window.c (Fdelete_window_internal): Invalidate the mouse
4215 highlight (Bug#9904).
4217 2012-02-12 Glenn Morris <rgm@gnu.org>

4222 * nsselect.m (Fx_own_selection_internal)
4223 (Fx_disown_selection_internal, Fx_selection_exists_p)
4224 (Fx_selection_owner_p, Fx_get_selection_internal):
4225 Sync docs and argument specs with the xselect.c versions.

4247 2012-02-07 Chong Yidong <cyd@gnu.org>
4249 * buffer.c (Fbuffer_local_variables)
4250 (buffer_lisp_local_variables): Handle unbound vars correctly;
4251 don't let Qunbound leak into Lisp.
4253 2012-02-07 Glenn Morris <rgm@gnu.org>
4255 * image.c (Fimagemagick_types): Doc fix.
4257 * image.c (imagemagick-render-type): Change it from a lisp object

4263 * doc.c (store_function_docstring): Avoid applying docstring of
4264 alias to base function (Bug#2603).
4266 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
4268 * .gdbinit (pp1, pv1): Remove redundant defines.

4290 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
4292 Handle overflow when computing char display width (Bug#9496).
4293 * character.c (char_width): Return EMACS_INT, not int.
4294 (char_width, c_string_width): Check for overflow when
4295 computing the width; this is possible now that individual
4296 characters can have unbounded width. Problem introduced
4297 by merge from Emacs 23 on 2012-01-19.
4299 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

4316 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
4317 0, do not call append_composite_glyph.

4328 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
4329 first 2 arguments are identical. This makes inserting large
4330 output from a subprocess an order of magnitude faster on
4331 MS-Windows, where all sbrk'ed memory is always contiguous.

4419 from load-path also when installation-directory is nil. (Bug#10208)
4421 2012-01-10 Glenn Morris <rgm@gnu.org>
4423 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

4430 * xdisp.c (rows_from_pos_range): Accept additional argument
4431 DISP_STRING, and accept any glyph in a row whose object is that
4432 string as eligible for mouse highlight. Fixes mouse highlight of
4433 display strings from overlays. (Bug#10464)
4435 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
4437 emacs: fix an auto-save permissions race condition (Bug#10400)
4438 * fileio.c (auto_saving_dir_umask): New static var.
4439 (Fmake_directory_internal): Use it.
4440 (do_auto_save_make_dir): Set it, instead of invoking chmod after
4441 creating the directory. The old code temporarily assigns
4442 too-generous permissions to the directory.
4443 (do_auto_save_eh): Clear it.
4444 (Fdo_auto_save): Catch all errors, not just file errors, so
4445 that the var is always cleared.

4449 * search.c (scan_buffer): Pass character positions to
4450 know_region_cache, not byte positions. (Bug#6540)

4502 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
4503 property that ends at ZV, so that the bidi iteration could be
4504 resumed from there (after widening). (Bug#10360)

4951 is set, removing the need for VIRT_ADDRESS_VARIES.
4952 (PURE_P): Use a more-efficient implementation that needs just one

4968 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
4969 behave as if the cursor position were at the window margin.
4971 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
4972 and the cursor position is out of bounds, behave as if the cursor
4973 position were at the window margin. (Bug#10075)

5470 * process.c (make_process): Initialize GnuTLS credentials to NULL.
5471 (deactivate_process): Call emacs_gnutls_deinit.
5473 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5475 * image.c (x_create_x_image_and_pixmap):
5476 * w32.c (sys_rename, w32_delayed_load):
5477 * w32font.c (fill_in_logfont):
5478 * w32reg.c (x_get_string_resource): Silence compiler warnings.
5480 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
5482 * w32fns.c (w32_default_color_map): New function,
5483 extracted from Fw32_default_color_map.
5484 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
5486 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
5488 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
5490 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
5492 * keyboard.c (test_undefined): New function (bug#9751).
5493 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
5495 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
5497 * sysdep.c (init_sys_modes): Fix the check for the controlling
5498 terminal (Bug#6649).
5500 2011-10-20 Eli Zaretskii <eliz@gnu.org>
5502 * dispextern.h (struct bidi_it): New member next_en_type.
5504 * bidi.c (bidi_line_init): Initialize the next_en_type member.
5505 (bidi_resolve_explicit_1): When next_en_pos is valid for the
5506 current character, check also for next_en_type being WEAK_EN.
5507 (bidi_resolve_weak): Don't enter the expensive loop if the current
5508 position is before next_en_pos. Record the bidi type of the first
5509 non-ET, non-BN character we find, in addition to its position.
5510 (bidi_level_of_next_char): Invalidate next_en_type when
5511 next_en_pos is over-stepped.
5513 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
5515 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5516 * editfns.c: Rewrite current-time-zone so that it invokes
5517 the equivalent of (format-time-string "%Z") to get the time zone name.
5518 This fixes a bug when the time zone name contains characters that
5519 need converting from the system time locale to Emacs internal format.
5520 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5521 that patch fixed format-time-string to do the conversion, but
5522 I forgot to fix current-time-zone.
5523 (format_time_string): New function, containing most of
5524 what Fformat_time_string used to contain.
5525 (Fformat_time_string): Rewrite in terms of format_time_string.
5526 This doesn't change this function's behavior.
5527 (current-time-zone): Rewrite to use format_time_string.
5528 This fixes the bug reported by Michael Schierl in
5529 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5530 Jason Rumney's 2007-06-07 change worked around this bug, but
5532 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5534 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5536 * xdisp.c (start_display): If the character at POS is displayed
5537 via a display vector, reset IT->current.dpvec_index to zero.
5538 (try_window_reusing_current_matrix): If a line ends in a display
5539 vector or the next line starts in a display vector, continue
5540 redrawing the window even though the character position of
5541 start_row was reached.
5544 2011-10-18 Chong Yidong <cyd@gnu.org>
5546 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5547 with nobreak-char-display too.
5549 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5551 Fix part 3 of bug#9771.
5552 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5553 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5554 non-neutral characters if the current character is a paragraph
5555 separator (a.k.a. Newline). This avoids running the same
5556 expensive loop twice, once when we consume the preceding newline
5557 and the other time when the line actually needs to be displayed.
5558 Avoid the loop when we see neutrals on the base embedding level
5559 following a character whose directionality is the same as the
5560 paragraph's. This avoids running the expensive loop when a line
5561 ends in a long sequence of neutrals, like control characters.
5562 Add assertion against STRONG_AL type. Slightly rearrange code
5563 that determines the type of a neutral given the first non-neutral
5565 (bidi_level_of_next_char): Set next_en_pos to zero when
5566 invalidating its info.
5568 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5570 * xdisp.c (push_display_prop): Determine whether to record string
5571 or buffer position by IT->string, not by IT->method. Allow
5572 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5573 (move_it_vertically_backward): Don't look for character position
5574 immediately after the newline when in a continuation line.
5577 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5579 * window.c (coordinates_in_window): Rewrite and delabelize
5580 vertical border check. (Bug#5357) (Bug#9618)
5582 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5584 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5585 errors in XSetWindowBorder (bug#9310).
5587 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5589 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5590 avoid crash when xmalloc overrun checking is enabled.
5592 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5594 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5595 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5596 cursor motion with <left> and <right> arrow keys.
5598 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5599 some callers set that themselves.
5601 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5603 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5604 display string and the previous row comes from the same string and
5605 is empty. (Bug#9739) (Bug#9738)
5607 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5609 * doc.c (get_doc_string): Encode file name (bug#9735).
5611 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5613 * bidi.c (bidi_level_of_next_char):
5614 * xdisp.c (get_visually_first_element): Remove old incorrect
5615 comments regarding the Unicode Line Separator character.
5617 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5619 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5621 * alloc.c (Fgc_status): Do not access beyond zombies array
5622 boundary if nzombies > MAX_ZOMBIES.
5623 * alloc.c (dump_zombies): Add missing format specifier.
5625 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5627 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5628 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5630 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5631 Some packages use them to denote characters with modifiers.
5633 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5635 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5636 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5637 matching a pp-number. Rename parameter var to var1.
5639 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5641 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5643 2011-10-08 Glenn Morris <rgm@gnu.org>
5645 * callint.c (Fcall_interactively): Give a more explicit error for the
5646 'c' case with a non-character input. (Bug#8479)
5648 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5650 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5652 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5653 lines that are hscrolled on the left.
5655 * dispnew.c (buffer_posn_from_coords): Account for a possible
5656 presence of header-line. (Bug#4426)
5658 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5660 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5661 Don't advertise functionality which we discourage or doesn't work.
5663 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5665 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5666 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5667 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5668 this makes Emacs dump core during garbage collection on rare
5669 occasions. sizeof is obviously inferior to offsetof here, so
5670 stick with offsetof.
5671 (GC_POINTER_ALIGNMENT): New macro.
5672 (mark_memory): Omit 3rd (offset) arg; caller changed.
5673 Don't assume EMACS_INT alignment is the same as pointer alignment.
5675 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5677 * keyboard.c (read_key_sequence_remapped): New var.
5678 (read_key_sequence): Compute remapping in the right buffer.
5679 (command_loop_1): Use read_key_sequence's remapping directly.
5681 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5683 * dired.c (file_name_completion): Don't expand file name.
5684 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5685 before checking file name handler.
5687 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5688 they've been requested explicitly (bug#9591).
5690 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5692 * keymap.c (Fsingle_key_description): Use make_specified_string
5693 instead of build_string to build string from push_key_description.
5696 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5698 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5699 This fixes a Y2038 bug on 64-bit hosts.
5700 * buffer.c (reset_buffer):
5701 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5702 (Fclear_buffer_auto_save_failure):
5703 Use 0, not -1, to represent an unset failure time, since time_t
5704 might not be signed.
5706 Remove dependency on glibc malloc internals.
5707 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5708 Move back here from lisp.h, but with their new implementations.
5709 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5710 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5711 * charset.c (charset_table_init): New static var.
5712 (syms_of_charset): Use it instead of xmalloc. This removes a
5713 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5714 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5715 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5716 Move back to alloc.c.
5717 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5718 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5720 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5722 * nsterm.m (windowDidResize): Call x_set_window_size only when
5723 ns_in_resize is true. Otherwise set pixelwidth/height and
5724 call change_frame_size (Bug#9628).
5726 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5728 Port --enable-checking=all to Fedora 14 x86-64.
5729 * charset.c (syms_of_charset): Also account for glibc malloc's
5730 internal overhead when calculating the initial malloc maximum.
5732 Port --enable-checking=all to Fedora 14 x86.
5733 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5735 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5736 (overrun_check_realloc, overrun_check_free):
5737 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5738 That way, xmalloc returns a properly-aligned pointer even if
5739 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5740 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5741 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5742 into account when calculating the initial malloc maximum.
5743 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5744 Move here from alloc.c, so that charset.c can use it too.
5745 Properly align; the old code wasn't right for common 32-bit hosts
5746 when configured with --enable-checking=all.
5747 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5748 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5750 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5752 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5755 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5757 * xdisp.c (compute_display_string_end): If there's no display
5758 string at CHARPOS, return -1.
5760 * bidi.c (bidi_fetch_char): When compute_display_string_end
5761 returns a negative value, treat the character as a normal
5762 character not covered by a display string. (Bug#9624)
5764 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5766 * lread.c (Fread_from_string): Fix typo in docstring.
5768 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5770 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5771 newline, reseat the iterator instead of bidi-iterating there one
5772 character at a time. (Bug#9610)
5773 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5774 TO_CHARPOS if the bidi iterator is at base embedding level.
5776 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5778 * lread.c (readevalloop): Use correct code for NBSP.
5779 (read1): Likewise. (Bug#9608)
5781 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5783 * dbusbind.c (Fdbus_register_signal): When service is not
5784 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5786 2011-09-25 Glenn Morris <rgm@gnu.org>
5788 * buffer.c (truncate-lines): Doc fix.
5790 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5792 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5793 (Fset_window_next_buffers): Doc fix.
5795 2011-09-24 Glenn Morris <rgm@gnu.org>
5797 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
5799 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
5801 Fix minor problems found by static checking.
5802 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
5803 * indent.c (Fvertical_motion): Fix == vs = typo.
5805 2011-09-24 Eli Zaretskii <eliz@gnu.org>
5807 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
5808 Default value is now t. Doc fix.
5810 * indent.c (Fvertical_motion): Compute and apply the overshoot
5811 logic when moving up, not only when moving down. Fix the
5812 confusing name and values of the it_overshoot_expected variable;
5813 logic changes accordingly. (Bug#9254) (Bug#9549)
5815 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
5816 CHARPOS is covered by a display string which includes newlines.
5817 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
5818 is covered by a display string with embedded newlines.
5820 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
5822 * dbusbind.c (Fdbus_register_signal): Add match rule to
5823 Vdbus_registered_objects_table. (Bug#9581)
5824 (Fdbus_register_method, Vdbus_registered_objects_table):
5827 2011-09-24 Jim Meyering <meyering@redhat.com>
5829 do not ignore write error for any output size
5830 The previous change was incomplete.
5831 While it makes emacs --batch detect the vast majority of stdout
5832 write failures, errors were still ignored whenever the output size is
5833 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
5834 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
5835 && echo FAIL: ignored write error
5836 FAIL: ignored write error
5837 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
5838 && echo FAIL: ignored write error
5839 FAIL: ignored write error
5840 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
5842 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
5844 * emacs.c (Fkill_emacs): In noninteractive mode exit
5845 non-successfully if a write error occurred on stdout. (Bug#9574)
5847 2011-09-21 Eli Zaretskii <eliz@gnu.org>
5849 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
5852 * dispextern.h (struct it): Update the comment documenting what
5855 2011-09-20 Eli Zaretskii <eliz@gnu.org>
5857 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
5858 a display string, extend search for cursor position to end of row.
5859 (find_row_edges): If the row ends in a newline from a display
5860 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
5861 Handle the case of a display string with multiple newlines.
5862 (Fcurrent_bidi_paragraph_direction): Fix search for previous
5863 non-empty line. Fixes confusing cursor motion with arrow keys at
5864 the beginning of a line that starts with whitespace.
5866 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
5868 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
5871 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
5873 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
5876 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5878 * xdisp.c (display_line): Record maximum and minimum buffer
5879 positions even if no glyphs were produced (e.g., by a zero-width
5880 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
5881 buffer positions that will be removed from the glyph row because
5883 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5884 column is beyond frame width: don't subtract 1 "pixel" when
5885 computing width of the stretch.
5886 (reseat_at_next_visible_line_start): Undo the change made on
5887 2011-09-17 that saved paragraph information and restored it after
5888 the call to `reseat'. (Bug#9545)
5890 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5892 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
5893 and turn window cursor on if cleared (Bug#9415).
5895 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
5897 * search.c (boyer_moore): Take unibyte characters from pattern
5898 literally. (Bug#9458)
5900 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5902 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
5904 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
5906 Fix minor problem found by static checking.
5907 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
5908 initialized, to pacify gcc -Wuninitialized.
5910 * fileio.c: Report proper errno when syscall falls.
5911 (Finsert_file_contents): Save and restore errno,
5912 so that report_file_error outputs the correct diagnostic.
5913 (Fwrite_region) [CLASH_DETECTION]: Likewise.
5915 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5917 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
5919 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5921 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
5922 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
5924 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5926 * xdisp.c (reseat_at_next_visible_line_start): Keep information
5927 about the current paragraph and restore it after the call to reseat.
5929 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
5930 (bidi_find_paragraph_start): Search back for paragraph beginning
5931 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
5932 (bidi_move_to_visually_next): Only trigger paragraph-related
5933 computations when the last character is a newline or at EOB, not
5934 just any NEUTRAL_B. (Bug#9470)
5936 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
5937 truncated lines if point is covered by a display string. (Bug#9524)
5939 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
5941 * xselect.c: Relax test for outgoing X longs (Bug#9498).
5942 (cons_to_x_long): New function.
5943 (lisp_data_to_selection_data): Use it. Correct the test for
5944 short-versus-long data; it was negated. Break out of vector
5945 loop, for efficiency, when a long datum is discovered.
5947 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
5949 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
5951 2011-09-16 Eli Zaretskii <eliz@gnu.org>
5953 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
5954 GCC PR/17406) by declaring this function with external scope.
5956 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5958 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
5959 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
5961 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
5963 * editfns.c (Fformat): Correctly handle text properties on "%%".
5965 2011-09-15 Eli Zaretskii <eliz@gnu.org>
5967 * xterm.c (x_draw_composite_glyph_string_foreground):
5968 * w32term.c (x_draw_composite_glyph_string_foreground):
5969 * term.c (encode_terminal_code):
5970 * composite.c (composition_update_it, get_composition_id):
5971 * xdisp.c (get_next_display_element)
5972 (fill_composite_glyph_string): Add comments about special meaning
5973 of TAB characters in a composition.
5975 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5977 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
5978 This occurs when processing a multibyte format.
5979 Problem reported by Wolfgang Jenker.
5981 2011-09-15 Johan Bockgård <bojohan@gnu.org>
5983 * xdisp.c (try_cursor_movement): Only check for exact match if
5984 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
5986 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5988 Remove unused external symbols.
5989 * dispextern.h (calc_pixel_width_or_height): Remove decl.
5990 * xdisp.c (calc_pixel_width_or_height): Now static.
5991 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
5992 * indent.c (check_display_width):
5993 * w32term.c: Fix comment to match code.
5994 * xterm.c, xterm.h (x_catching_errors): Remove.
5996 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5998 * xselect.c: Use signed conversions more consistently (Bug#9498).
5999 (selection_data_to_lisp_data): Assume incoming selection data are
6000 signed integers, not unsigned. This is to be consistent with
6001 outgoing selection data, which was modified to use signed integers
6002 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6003 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6004 expects long, not unsigned long.
6006 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6008 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6009 computation of loop end. Reported by Johan Bockgård
6012 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6014 * frame.c (Fother_visible_frames_p): Function deleted.
6016 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6018 * indent.c (compute_motion): Process display vector front to back
6019 rather than the other way around. (Bug#2496)
6021 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6023 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6025 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6027 * minibuf.c (Fread_from_minibuffer): Doc fix.
6029 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6031 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6032 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6034 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6036 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6037 value for non-existent files.
6039 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6041 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6042 set its "size" to -1. This will set the modtime_size field of
6043 the corresponding buffer to -1, which is what
6044 verify-visited-file-modtime expects for files that do not exist.
6047 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6049 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6051 * lisp.h: ... from here. push_key_description is no longer
6052 defined in keyboard.c, so its declaration should not be in
6053 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6054 logically belongs with push_key_description.
6056 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6058 * buffer.h: Include <sys/types.h> instead of <time.h>.
6059 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6060 Problem reported by Herbert J. Skuhra.
6062 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6064 * xml.c (parse_region): Make the parsing work for
6065 non-comment-starting XML files again (bug#9144).
6067 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6069 * image.c (gif_load): Fix calculation of bottom and right corner.
6072 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6074 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6075 redisplay in small windows.
6077 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6079 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6081 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6083 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6084 Operate on live windows only.
6086 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6088 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6090 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6092 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6093 only under bidi iteration.
6095 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6097 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6099 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6101 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6102 Without this fix, the command to link temacs failed due to an
6103 undefined symbol __builtin_isnan. This is because
6104 /usr/include/iso/math_c99.h #defines isnan(x) to
6105 __builtin_isnan(x), but the bundled gcc, which identifies itself
6106 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6108 * floatfns.c (isnan): #undef, and then #define to a clone of
6110 (Fisnan): Always define, since it's always available now.
6111 (syms_of_floatfns): Always define isnan at the Lisp level.
6113 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6115 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6117 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6119 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6120 The previous code assumed that file offsets (off_t values) fit in
6121 EMACS_INT variables, which is not true on typical 32-bit hosts.
6122 The code messed up by falsely reporting buffer overflow in cases
6123 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6124 when "big" contains more than 2**29 bytes, even though this
6125 inserts just one byte and does not overflow the buffer.
6126 (Finsert_file_contents): Store file offsets as off_t
6127 values, not as EMACS_INT values. Check for overflow when
6128 converting between EMACS_INT and off_t. When checking for
6129 buffer overflow or for overlap, take the offsets into account.
6130 Don't use EMACS_INT for small values where int suffices.
6131 When checking for overlap, fix a typo: ZV was used where
6132 ZV_BYTE was intended.
6133 (Fwrite_region): Don't assume off_t fits into 'long'.
6134 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6136 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6138 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6140 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6142 sprintf-related integer and memory overflow issues (Bug#9412).
6144 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6145 (esprintf, exprintf, evxprintf): New functions.
6146 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6147 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6148 (modify_event_symbol): Do not assume that the length of
6149 name_alist_or_stem is safe to alloca and fits in int.
6150 (Fexecute_extended_command): Likewise for function name and binding.
6151 (Frecursion_depth): Wrap around reliably on integer overflow.
6152 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6153 since some callers pass EMACS_INT values.
6154 (Fsingle_key_description): Don't crash if symbol name contains more
6155 than MAX_ALLOCA bytes.
6156 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6157 (get_minibuffer): Arg is now EMACS_INT, not int.
6158 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6159 (esprintf, exprintf, evxprintf): New decls.
6160 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6162 * dbusbind.c (signature_cat): New function.
6163 (xd_signature, Fdbus_register_signal):
6164 Do not overrun buffer; instead, report string overflow.
6166 * dispnew.c (add_window_display_history): Don't overrun buffer.
6167 Truncate instead; this is OK since it's just a log.
6169 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6170 even if the time zone offset is outlandishly large.
6171 Don't mishandle offset == INT_MIN.
6173 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6174 when creating daemon; the previous buffer-overflow check was incorrect.
6176 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6177 which has the guts of the old verror function.
6179 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6180 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6182 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6183 (font_unparse_xlfd): Don't blindly alloca long strings.
6184 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6185 fits in int, when using sprintf. Use single snprintf to count
6186 length of string rather than counting it via multiple sprintfs;
6187 that's simpler and more reliable.
6188 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6189 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6190 sprintf, in case result does not fit in int.
6192 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6193 (fontset_from_font): Print it.
6195 * frame.c (tty_frame_count): Now printmax_t, not int.
6196 (make_terminal_frame, set_term_frame_name): Print it.
6197 (x_report_frame_params): In X, window IDs are unsigned long,
6198 not signed long, so print them as unsigned.
6199 (validate_x_resource_name): Check for implausibly long names,
6200 and don't assume name length fits in 'int'.
6201 (x_get_resource_string): Don't blindly alloca invocation name;
6202 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6205 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6206 (xg_check_special_colors, xg_set_geometry):
6207 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6209 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6210 Use esprintf, not sprintf, in case result does not fit in int.
6212 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6213 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6214 it as a large positive number.
6215 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6216 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6218 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6219 in case result does not fit in int.
6221 * print.c (float_to_string): Detect width overflow more reliably.
6222 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6223 buffer overrun. Don't assume list length fits in 'int'. Treat
6224 print length of 0 as 0, not as infinity; to be consistent with other
6225 uses of print length in this function. Don't overflow print length
6226 index. Don't assume hash table size fits in 'long', or that
6227 vectorlike size fits in 'unsigned long'.
6229 * process.c (make_process): Use printmax_t, not int, to format
6230 process-name gensyms.
6232 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6234 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6235 to avoid potential buffer overrun.
6237 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6238 if X resource line is longer than 512 bytes.
6240 * xfns.c (x_window): Make sprintf buffer a bit bigger
6241 to avoid potential buffer overrun.
6243 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6245 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6247 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6249 Integer overflow fixes for scrolling, etc.
6250 Without these, Emacs silently mishandles large integers sometimes.
6251 For example, "C-u 4294967297 M-x recenter" was treated as if
6252 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6254 * xdisp.c (try_window_id): Check Emacs fixnum range before
6255 converting to 'int'.
6257 * window.c (window_scroll_line_based, Frecenter):
6258 Check that an Emacs fixnum is in range before assigning it to 'int'.
6259 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6260 values converted from Emacs fixnums.
6261 (Frecenter): Don't wrap around a line count if it is out of 'int'
6262 range; instead, treat it as an extreme value.
6263 (Fset_window_configuration, compare_window_configurations):
6264 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6266 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6267 that can exceed INT_MAX. Check that EMACS_INT value is in range
6268 before assigning it to the (possibly-narrower) index.
6269 (match_limit): Don't assume that a fixnum can fit in 'int'.
6271 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6274 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6275 (Fvertical_motion): Don't wrap around LINES values that don't fit
6276 in 'int'. Instead, treat them as extreme values. This is good
6277 enough for windows, which can't have more than INT_MAX lines anyway.
6279 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6281 * Require libxml/parser.h to avoid compilation warning.
6283 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6285 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6286 since this reportedly can destroy thread storage.
6288 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6290 * syntax.c (find_defun_start): Update all cache variables if
6291 exiting early (Bug#9401).
6293 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6295 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6297 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6298 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6299 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6301 * term.c (tty_append_glyph): New function.
6302 (produce_stretch_glyph): Static function and its prototype deleted.
6304 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6307 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6309 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6310 when checking :margin (Bug#9390).
6311 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6312 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6313 so that the name doesn't mislead. All uses changed.
6315 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6317 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6320 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6322 * xdisp.c (move_it_to): Don't bail out early when reaching
6323 position beyond to_charpos, if we are scanning backwards.
6324 (move_it_vertically_backward): When DY == 0, make sure we get to
6325 the first character in the line after the newline.
6327 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6329 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6330 (ccl_driver): Do not generate an out-of-range pointer.
6331 (Fccl_execute_on_string): Remove unnecessary check for
6332 integer overflow, noted by Stefan Monnier in
6333 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6334 Remove a FIXME that didn't need fixing.
6335 Simplify the newly-introduced buffer reallocation code.
6337 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6339 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6341 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6343 Integer and memory overflow issues (Bug#9196).
6345 * doc.c (get_doc_string): Rework so that
6346 get_doc_string_buffer_size is the actual buffer size, rather than
6347 being 1 less than the actual buffer size; this makes xpalloc more
6350 * image.c (x_allocate_bitmap_record, cache_image):
6351 * xselect.c (Fx_register_dnd_atom):
6352 Simplify previous changes by using xpalloc.
6354 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6355 since either will do and ptrdiff_t is convenient with xpalloc.
6357 * charset.c (charset_table_size)
6358 (struct charset_sort_data.priority): Now ptrdiff_t.
6359 (charset_compare): Don't overflow if priorities differ greatly.
6360 (Fsort_charsets): Don't assume list length fits in int.
6361 Check for size-calculation overflow when allocating sort data.
6362 (syms_of_charset): Allocate an initial charset table that is
6363 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6365 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6367 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6368 The actual value is always <= INT_MAX, and leaving it unsigned made
6369 overflow checking harder.
6371 * dispextern.h (struct glyph_matrix.rows_allocated)
6372 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6373 with xpalloc. The values are still always <= INT_MAX.
6375 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6377 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6378 (SAFE_NALLOCA): New macro.
6380 * region-cache.c (struct boundary.pos, find_cache_boundary)
6381 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6382 (set_cache_region, invalidate_region_cache)
6383 (revalidate_region_cache, know_region_cache, region_cache_forward)
6384 (region_cache_backward, pp_cache):
6385 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6386 so that ptrdiff_t * can be passed to xpalloc.
6387 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6388 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6389 (pp_cache): Don't assume cache_len fits in int.
6390 * region-cache.h: Adjust extern decls to match.
6392 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6393 EMACS_INT, since either will do, for xpalloc.
6395 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6396 (xnmalloc, xnrealloc, xpalloc): New functions.
6398 * bidi.c (bidi_shelve_header_size): New constant.
6399 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6400 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6402 * bidi.c (bidi_cache_shrink):
6403 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6405 Don't update size of array until after memory allocation succeeds,
6406 because xmalloc/xrealloc may not return.
6407 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6408 now that we have proper integer overflow checking.
6409 (record_overlay_string, overlay_strings): Catch overflows when
6410 calculating size of overlay_str_buf.
6412 * callproc.c (Fcall_process): Check for size overflow when
6413 calculating size of args2.

6461 * emacs.c (main): Do not reallocate argv, since there is a null at
6462 the end that can be overwritten, and this way there's no need to
6463 worry about size-calculation overflow.
6464 (sort_args): Check for size-calculation overflow.
6466 * eval.c (init_eval_once, grow_specpdl): Don't update size until

6593 (X_LONG_MIN): New macros.
6594 Use them to make the following changes clearer.
6595 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

6598 (SELECTION_QUANTUM): Remove, replacing with ...
6599 (selection_quantum): ... new function, which avoids overflow.
6601 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

6619 Don't store size until memory allocation succeeds.
6620 (x_get_window_property): Plug memory leak on memory exhaustion.
6621 Don't double-block input; malloc is safe here. Don't assume 2**34
6622 - 4 fits in unsigned long. Add an xassert to check
6623 XGetWindowProperty overflow. Be more careful about overflow
6624 calculations, and distinguish size from memory overflow better.

6630 in the range -65535 through -1 fit in an X unsigned short.
6631 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into

6668 * lisp.h (hash_lookup, hash_put):
6669 * minibuf.c (Ftest_completion):
6670 Use ptrdiff_t for hash table indexes, not int (which is too

6710 (make_lispy_movement): Use same integer type in forward decl
6711 that is used in the definition.
6712 (read_key_sequence, keyremap_step):
6713 Change bufsize argument back to int, undoing my 2011-03-30 change.

6715 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6716 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow

6718 length, not size_t. Use ptrdiff_t for index, not int.

6748 Prefer int to unsigned where either will do.
6749 (tiff_handler): New function, combining the cores of the
6750 old tiff_error_handler and tiff_warning_handler.
6751 This function is rewritten to use vsnprintf and thereby avoid
6752 stack buffer overflows. It uses only the features of vsnprintf
6753 that are common to both POSIX and native Microsoft.
6754 (tiff_error_handler, tiff_warning_handler): Use it.
6755 (tiff_load, gif_load, imagemagick_load_image):

6776 (handle_single_display_spec): If the display spec is of the form
6777 `(space ...)', and specifies display in the text area, return 2
6779 (try_cursor_movement): Check for the need to scroll more
6780 accurately, and prefer exact match for point under bidi.
6781 Don't advance `row' beyond the last row of the window.
6783 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6784 into disp_prop; all users changed.

6802 positioning on the newline at EOL of R2L text within L2R
6803 paragraph, and vice versa.
6804 (try_cursor_movement): Check continued rows, in addition to
6805 continuation rows. Fixes unwarranted scroll when point enters a
6806 continued line of R2L text within an L2R paragraph, or vice versa.
6807 (cursor_row_p): Consider the case of point being equal to
6808 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
6809 from the end of a short line to the beginning of a continued line
6810 of R2L text within L2R paragraph.
6811 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

6837 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6838 instead of CHAR_TO_BYTE. Fixes a crash when a completion
6839 candidate is selected by the mouse, and that candidate has a
6840 composed character under the mouse.
6842 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
6843 coordinates reported by pos-visible-in-window-p for a composed

6854 composed buffer positions.
6856 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
6858 * image.c (gif_load): Don't assume that each subimage has the same
6859 dimensions as the base image. Handle disposal method that is
6860 "undefined" by the gif spec (Bug#9335).

6865 (Fcondition_case): Document `debug' symbol in error handler.
6867 2011-08-19 Eli Zaretskii <eliz@gnu.org>
6869 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
6870 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
6871 from an Org mode buffer to a Speedbar frame.
6873 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
6874 a composition, take its buffer position from IT->cmp_it.charpos.
6875 Fixes cursor positioning at the beginning of a line that begins
6876 with a composed character.
6878 2011-08-18 Eli Zaretskii <eliz@gnu.org>
6880 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
6881 character bidirectional type, use STRONG_L instead. Fixes crashes
6882 in a buffer produced by `describe-categories'.
6884 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
6885 members before the level stack, so they would be saved and
6886 restored when copying iterator state. Fixes incorrect reordering
6887 around TABs covered by display properties.
6889 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
6891 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
6893 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
6895 * eval.c (internal_condition_case, internal_condition_case_1)
6896 (internal_condition_case_2, internal_condition_case_n):
6897 Remove unnecessary aborts (Bug#9081).
6899 2011-08-17 Eli Zaretskii <eliz@gnu.org>
6901 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
6902 has no `load' handler, try opening the file locally. (Bug#9311)
6904 2011-08-16 Ken Brown <kbrown@cornell.edu>
6906 * gmalloc.c: Expand comment.
6908 2011-08-16 Eli Zaretskii <eliz@gnu.org>

6913 2011-08-16 Ken Brown <kbrown@cornell.edu>
6915 Fix memory allocation problems in Cygwin build (Bug#9273).
6917 * unexcw.c ( __malloc_initialized): Declare external variable.
6918 (fixup_executable): Force the dumped emacs to reinitialize malloc.
6920 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
6922 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
6924 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
6926 [CYGWIN] (special_realloc): New function.
6927 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
6928 requests to realloc storage in the static heap.

6941 * dispextern.h: Fix a typo in the comment to bidi_type_t.
6943 * chartab.c: Improve commentary for the uniprop_table API.
6945 * bidi.c (bidi_paragraph_init): Support zero value of
6946 bidi_ignore_explicit_marks_for_paragraph_level.
6947 (bidi_initialize): Use uniprop_table instead of including
6948 biditype.h and bidimirror.h.
6950 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
6951 coordinates of the iterator when restoring from ppos_it.
6954 2011-08-14 Kenichi Handa <handa@m17n.org>
6956 * process.c (create_process): Call setup_process_coding_systems
6957 after the pid of the process is set to -1 (Bug#8162).
6959 2011-08-14 Eli Zaretskii <eliz@gnu.org>
6961 * xdisp.c (move_it_in_display_line_to): Don't invoke
6962 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
6963 ppos_it. Fixes vertical cursor motion when line beginning is
6964 covered by an image. (Bug#9296)
6966 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
6968 * nsterm.h (ns_run_ascript): Declare.
6969 (NSAPP_DATA2_RUNASSCRIPT): Define.
6971 * nsfns.m (as_script, as_result, as_status): New static variables.
6972 (ns_run_ascript): New function.
6973 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
6974 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
6975 the event loop. Get status from as_status (Bug#7276).
6977 * nsterm.m (sendEvent): If event is NSApplicationDefined and
6978 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
6979 the event loop (Bug#7276).
6981 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
6983 * gnutls.c (QCgnutls_bootprop_priority)
6984 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
6985 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
6986 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
6987 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
6988 (QCgnutls_bootprop_verify_hostname_error)
6989 (QCgnutls_bootprop_callbacks_verify): Rename from
6990 Qgnutls_bootprop_..., all uses changed.

7002 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
7004 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7005 (Fnetwork_interface_list): Allocate in increments of bytes instead
7006 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7007 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7009 (struct ifflag_def): notrailers is smart on OSX.
7010 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7011 Get hardware address with getifaddrs if available.
7013 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7015 * xdisp.c (iterate_out_of_display_property): xassert that
7016 IT->position is set to within IT->object's boundaries. Break from
7017 the loop as soon as EOB is reached; avoids infloops in redisplay
7018 when IT->position is set up wrongly due to some bug.
7019 Set IT->current to match the bidi iterator unconditionally.
7020 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7021 entry. Force push_it to save on the stack the current
7022 buffer/string position, to be restored by pop_it. Fix flags in
7023 the iterator structure wrt the object coming from a display
7024 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7025 properties. (Bug#9284)
7027 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7029 * fontset.c (fontset_get_font_group): Add proper type checks.

7037 (dump_it) [LC_FUNCTION_STARTS]: Use it.
7039 2011-08-08 Eli Zaretskii <eliz@gnu.org>
7041 * xdisp.c (forward_to_next_line_start): Allow to use the
7042 no-display-properties-and-no-overlays under bidi display.
7043 Set disp_pos in the bidi iterator to avoid searches for display
7044 properties and overlays.
7046 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7048 * editfns.c (Fset_time_zone_rule): Document relationship with the
7051 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
7052 the font entity extracted from the cache (Bug#8109).
7054 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7056 * composite.c (autocmp_chars): Don't reset point. That is done by
7057 restore_point_unwind (Bug#5984).
7059 2011-08-07 Juri Linkov <juri@jurta.org>
7061 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7062 to show the arg `TIME' instead of `TIMEVAL'.
7064 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7066 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7067 display property strides EOL and includes a newline, as in
7068 longlines-mode. (Bug#9254)
7069 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7070 word-wrap under bidirectional display. (Bug#9224)
7072 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7073 is non-zero, even if the data buffer is NULL. Fixes a crash in
7074 vertical-motion with longlines-mode. (Bug#9254)
7076 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7078 * bidi.c <bidi_cache_total_alloc>: Now static.
7079 (bidi_initialize): Initialize bidi_cache_total_alloc.
7081 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7084 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7085 amount allocated this far in `bidi_cache_total_alloc'.
7086 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7087 non-zero, only free the data buffer without restoring the cache
7088 contents. All callers changed.
7090 * dispextern.h (bidi_unshelve_cache): Update prototype.
7092 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7093 (move_it_in_display_line, move_it_to)
7094 (move_it_vertically_backward, move_it_by_lines): Replace the call
7095 to xfree to an equivalent call to bidi_unshelve_cache.
7096 (move_it_in_display_line_to): Fix logic of returning
7097 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7099 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7101 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7102 came from a string character with a `cursor' property. (Bug#9229)
7104 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7106 * Makefile.in (LIB_PTHREAD): New variable.
7107 (LIBES): Add LIB_PTHREAD (Bug#9216).
7109 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7110 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
7112 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
7114 * regex.c (re_iswctype): Remove some redundant boolean conversions.
7116 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7118 * xterm.c (x_find_topmost_parent): New function.
7119 (x_set_frame_alpha): Find topmost parent window with
7120 x_find_topmost_parent and set the property there also (bug#9181).
7121 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
7123 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
7125 * callproc.c (Fcall_process): Avoid vfork clobbering
7126 the local vars buffer, coding_systems, current_dir.
7128 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
7130 * keymap.c (Fmake_composed_keymap): Move to subr.el.
7132 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
7134 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
7135 so that it is not optimized away.
7137 * xdisp.c (compute_display_string_pos): Remove unused local.
7139 2011-08-02 Eli Zaretskii <eliz@gnu.org>
7141 Fix slow cursor motion and scrolling in large buffers with
7142 selective display, like Org Mode buffers. (Bug#9218)
7144 * dispextern.h (struct bidi_it): New member disp_prop_p.
7146 * xdisp.c: Remove one-slot cache of display string positions.
7147 (compute_display_string_pos): Accept an additional argument
7148 DISP_PROP_P; callers changed. Scan at most 5K characters forward
7149 for a display string or property. If found, set DISP_PROP_P
7152 * bidi.c (bidi_fetch_char): Accept an additional argument
7153 DISP_PROP_P, and pass it to compute_display_string_pos.
7154 Only handle text covered by a display string if DISP_PROP_P is returned
7155 non-zero. All callers of bidi_fetch_char changed.
7157 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
7159 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
7161 2010-12-03 Don March <don@ohspite.net>
7163 * keymap.c (Fdefine_key): Fix non-prefix key error message when
7164 last character M-[char] is translated to ESC [char] (bug#7541).
7166 2011-08-02 Kenichi Handa <handa@m17n.org>
7168 * lisp.h (uniprop_table): Extern it.
7170 * chartab.c (uniprop_table): Make it non-static.
7172 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7174 * xdisp.c (forward_to_next_line_start): Accept additional argument
7175 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7177 (reseat_at_next_visible_line_start): Use the bidi iterator state
7178 returned by forward_to_next_line_start to restore the state of
7179 it->bidi_it after backing up to previous newline. (Bug#9212)
7181 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7183 * regex.c (re_comp): Protoize.
7184 (re_exec): Fix return type.
7185 (regexec): Fix type of `ret'. (Bug#9203)
7187 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7189 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7190 This is needed if max-image-size is a floating-point number.
7192 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7194 * print.c (print_object): Print empty symbol as ##.
7196 * lread.c (read1): Read ## as empty symbol.
7198 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7200 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7201 setting frame foreground color (Bug#9175).
7202 (x_set_background_color): Likewise.
7204 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7205 contents (Bug#9176).
7206 (EmacsTooltip -init): Remove bezels and add shadows to
7209 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7210 or scroll bar (Bug#8470).
7212 * nsfont.m (nsfont_open): Remove assignment to voffset and
7213 unnecessary vars hshink, expand, hd, full_height, min_height.
7214 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7216 * nsterm.h (nsfont_info): Remove voffset field.
7218 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7220 Implement strike-through and overline on NextStep (Bug#8863).
7222 * nsfont.m (nsfont_open): Use underline position provided by font,
7223 instead of hard-coded value of 2.
7224 (nsfont_draw): Call ns_draw_text_decoration instead.
7226 * nsterm.h: Add declaration for ns_draw_text_decoration.
7228 * nsterm.m (ns_draw_text_decoration): New function for drawing
7229 underline, overline, and strike-through.
7230 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
7231 ns_draw_text_decoration. Change treatment of cursor drawing to
7232 accommodate underlining, etc.
7234 2011-07-28 Eli Zaretskii <eliz@gnu.org>
7236 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7239 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7241 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7242 Without this fix, if a signal arrives just after memory fills up,
7243 'malloc' might be invoked reentrantly.
7245 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7246 In other words, assume that every image size is allowed, on non-X
7247 hosts. This assumption is probably wrong, but it lets Emacs compile.
7249 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7251 * regex.c (re_iswctype): Convert return values to boolean.
7253 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7255 * xdisp.c (compute_display_string_pos): Don't use cached display
7256 string position if the buffer had its restriction changed.
7259 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7261 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7263 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7265 Integer signedness and overflow and related fixes. (Bug#9079)
7267 * bidi.c: Integer size and overflow fixes.
7268 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7269 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7270 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7271 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7272 (bidi_find_other_level_edge):
7273 Use ptrdiff_t instead of EMACS_INT where either will do.
7274 This works better on 32-bit hosts configured --with-wide-int.
7275 (bidi_cache_ensure_space): Check for size-calculation overflow.
7276 Use % rather than repeated addition, for better worst-case speed.
7277 Don't set bidi_cache_size until after xrealloc returns, because it
7279 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7280 (bidi_cache_ensure_space): Also check that the bidi cache size
7281 does not exceed that of the largest Lisp string or buffer. See Eli
7282 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7284 * alloc.c (__malloc_size_t): Remove.
7285 All uses replaced by size_t. See Andreas Schwab's note
7286 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7288 * image.c: Improve checking for integer overflow.
7289 (check_image_size): Assume that f is nonnull, since
7290 it is always nonnull in practice. This is one less thing to
7291 worry about when checking for integer overflow later.
7292 (x_check_image_size): New function, which checks for integer
7293 overflow issues inside X.
7294 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7295 This removes the need for a memory_full check.
7296 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7297 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7298 (xbm_read_bitmap_data): Change locals back to 'int', since
7299 their values must fit in 'int'.
7300 (xpm_load_image, png_load, tiff_load):
7301 Invoke x_create_x_image_and_pixmap earlier,
7302 to avoid much needless work if the image is too large.
7303 (tiff_load): Treat overly large images as if
7304 x_create_x_image_and_pixmap failed, not as malloc failures.
7305 (gs_load): Use x_check_image_size.
7307 * gtkutil.c: Omit integer casts.
7308 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7309 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7311 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7313 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7314 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7315 would wrongly return t on a 64-bit host.
7317 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7318 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7319 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7320 and therefore cause GCC to emit a bogus diagnostic in some cases.
7322 * image.c: Integer signedness and overflow and related fixes.
7323 This is not an exhaustive set of fixes, but it's time to
7324 record what I've got.
7325 (lookup_pixel_color, check_image_size): Remove redundant decls.
7326 (check_image_size): Don't assume that arbitrary EMACS_INT values
7327 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7328 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7329 (tiff_load, imagemagick_load_image):
7330 Check for overflow in size calculations.
7331 (x_create_x_image_and_pixmap): Remove unnecessary test for
7332 xmalloc returning NULL; that can't happen.
7333 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7334 (xpm_color_bucket): Use better integer hashing function.
7335 (xpm_cache_color): Don't possibly over-allocate memory.
7336 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7337 (gif_memory_source):
7338 Use ptrdiff_t, not int or size_t, to record sizes.
7339 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7340 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7341 either works, as we prefer signed integers.
7342 (tiff_read_from_memory, tiff_write_from_memory):
7343 Return tsize_t, not size_t, since that's what the TIFF API wants.
7344 (tiff_read_from_memory): Don't fail simply because the read would
7345 go past EOF; instead, return a short read.
7346 (tiff_load): Omit no-longer-needed casts.
7347 (Fimagemagick_types): Don't assume size fits into 'int'.
7349 Improve hashing quality when configured --with-wide-int.
7350 * fns.c (hash_string): New function, taken from sxhash_string.
7351 Do not discard information about ASCII character case; this
7352 discarding is no longer needed.
7353 (sxhash-string): Use it. Change sig to match it. Caller changed.
7354 * lisp.h: Declare it.
7355 * lread.c (hash_string): Remove, since we now use fns.c's version.
7356 The fns.c version returns a wider integer if --with-wide-int is
7357 specified, so this should help the quality of the hashing a bit.
7359 * emacs.c: Integer overflow minor fix.
7360 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7361 Define only if GNU_LINUX.
7362 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7364 * dispnew.c: Integer signedness and overflow fixes.
7365 Remove unnecessary forward decls, that were a maintenance hassle.
7366 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7368 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7369 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7370 (prepare_desired_row, line_draw_cost):
7371 Use int, not unsigned, where either works.
7372 (save_current_matrix, restore_current_matrix):
7373 Use ptrdiff_t, not size_t, where either works.
7374 (init_display): Check for overflow more accurately, and without
7375 relying on undefined behavior.
7377 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7378 Remove, replacing with the new symbols in lisp.h. All uses changed.
7379 * fileio.c (make_temp_name):
7380 * filelock.c (lock_file_1, lock_file):
7381 * xdisp.c (message_dolog):
7382 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7383 Use pMd etc. instead.
7384 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7385 replacing the pWIDE etc. symbols removed from editfns.c.
7387 * keyboard.h (num_input_events): Now uintmax_t.
7388 This is (very slightly) less likely to mess up due to wraparound.
7391 * buffer.c: Integer signedness fixes.
7392 (alloc_buffer_text, enlarge_buffer_text):
7393 Use ptrdiff_t rather than size_t when either will do, as we prefer
7396 * alloc.c: Integer signedness and overflow fixes.
7397 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7398 (__malloc_size_t): Default to size_t, not to int.
7399 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7400 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7401 Prefer ptrdiff_t to size_t when either would do, as we prefer
7403 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7404 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7405 Now const. Initialize with values that are in range even if char
7407 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7408 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7409 These functions do the right thing with sizes > 2**32.
7410 (check_depth): Now ptrdiff_t, not int.
7411 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7412 Adjust to new way of storing sizes. Check for size overflow bugs
7414 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7415 slightly wrong anyway, as it missed one instance of
7416 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7417 (refill_memory_reserve): Omit needless cast to size_t.
7418 (mark_object_loop_halt): Mark as externally visible.
7420 * xselect.c: Integer signedness and overflow fixes.
7421 (Fx_register_dnd_atom, x_handle_dnd_message):
7422 Use ptrdiff_t, not size_t, since we prefer signed.
7423 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7424 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7425 x_dnd_atoms_size and x_dnd_atoms_length.
7427 * doprnt.c: Prefer signed to unsigned when either works.
7429 * doprnt.c (doprnt):
7431 * xdisp.c (vmessage):
7432 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7433 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7434 prefer signed arithmetic to avoid comparison confusion.
7435 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7436 but is a bit tricky.
7438 Assume freestanding C89 headers, string.h, stdlib.h.
7439 * data.c, doprnt.c, floatfns.c, print.c:
7440 Include float.h unconditionally.
7441 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7442 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7443 * regex.c: Likewise for stddef.h, string.h.
7444 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7445 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7446 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7447 (STDC_HEADERS): Remove obsolete defines.
7448 * sysdep.c: Include limits.h unconditionally.
7450 Assume support for memcmp, memcpy, memmove, memset.
7451 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7452 * regex.c (memcmp, memcpy):
7453 Remove; we assume C89 now.
7455 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7456 (__malloc_safe_bcopy): Remove; no longer needed.
7458 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7459 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7460 well either way, and we prefer signed to unsigned.
7462 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7464 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7465 closes the connection while we're reading (bug#9182).
7467 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7469 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7470 are specified (Bug#9168).
7472 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7474 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7475 Found by GCC static checking and --with-wide-int on a 32-bit host.
7477 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7479 * xdisp.c (compute_display_string_pos): Fix logic of caching
7480 previous display string position. Initialize cached_prev_pos to
7481 -1. Fixes slow-down at the beginning of a buffer.
7483 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7485 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7486 for attrs[LFACE_FONTSET_INDEX].
7488 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7490 * xml.c (parse_region): Remove unused local
7491 that was recently introduced.
7493 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7495 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7496 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7498 * xdisp.c (move_it_in_display_line_to): Record the best matching
7499 position for TO_CHARPOS while scanning the line, and restore it on
7500 exit if none of the characters scanned was an exact match.
7501 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7502 when exact match is impossible due to invisible text, and the
7503 lines are truncated.
7505 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7507 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7510 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7512 Fix a significant slow-down of cursor motion with C-n, C-p,
7513 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7514 auto-repeat under bidi redisplay in fontified buffers.
7515 * xdisp.c (compute_stop_pos_backwards): New function.
7516 (next_element_from_buffer): Call compute_stop_pos_backwards to
7517 find a suitable prev_stop when we find ourselves before
7519 (reseat): Don't look for prev_stop, as that could mean a very long
7521 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7522 <cached_disp_overlay_modiff>: Cache for last found display string
7524 (compute_display_string_pos): Return the cached position if asked
7525 about the same buffer in the same area of character positions, and
7526 the buffer wasn't changed since the time the display string
7527 position was cached.
7529 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7531 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7532 is an integer, which is important for empty lines. (Bug#9149)
7534 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7536 * frame.c (Fmodify_frame_parameters): In tty case, update the
7537 default face if necessary (Bug#4238).
7539 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7541 * editfns.c (Fstring_to_char): No need to explain what a character
7542 is in the docstring (Bug#6576).
7544 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7546 * xml.c (parse_region): Make sure we always return a tree.
7548 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7550 * xml.c (parse_region): If a document contains only comments,
7553 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7555 * xml.c (make_dom): Return comments, too.
7557 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7560 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7561 and the surrounding thread.
7562 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7563 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7564 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7566 * s/openbsd.h (BROKEN_SIGIO): Define.
7567 * unexelf.c (unexec) [__OpenBSD__]:
7568 Don't update the .mdebug section of the Alpha COFF symbol table.
7570 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7572 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7575 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7577 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7578 This fixes some race conditions on the permissions of any newly
7581 * alloc.c (valid_pointer_p): Use pipe, not open.
7582 This fixes some permissions issues when debugging.
7584 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7585 If fchown fails to set both uid and gid, try to set just gid,
7586 as that is sometimes allowed. Adjust the file's mode to eliminate
7587 setuid or setgid bits that are inappropriate if fchown fails.
7589 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7591 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7592 to compare Lisp_Objects.
7593 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7594 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7595 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7597 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7599 * lread.c (read_integer): Unread even EOF character.
7600 (read1): Likewise. Properly record start position of symbol.
7602 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7603 symbol character follows.
7605 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7607 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7608 This works around a problem with the previous change to Fcopy_file.
7609 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7610 and without this change, GCC might complain about discarding
7611 fchown's return value.
7613 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7615 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7617 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7619 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7621 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7623 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7624 it's used from the C level.
7626 * process.c: Use the same condition for POLL_FOR_INPUT in both
7627 keyboard.c and process.c (bug#1858).
7629 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7631 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7632 (Fgnutls_boot): Use it.
7634 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7636 * doc.c (Fsubstitute_command_keys): Revert last change.
7638 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7640 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7641 quotes the next character, and doesn't affect other longer
7642 sequences (bug#8935).
7644 * lread.c (syms_of_lread): Clarify that is isn't only
7645 `eval-buffer' and `eval-defun' that's affected by
7646 `lexical-binding' (bug#8460).
7648 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7650 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7651 bidi redisplay when a line includes both an image and is truncated.
7653 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7655 Fix minor problems found by static checking.
7656 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7657 (elsz): Now a signed constant, not a size_t var. We prefer signed
7658 types to unsigned, to avoid integer comparison confusion. Without
7659 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7660 "cannot optimize loop, the loop counter may overflow", a symptom
7662 * indent.c (Fvertical_motion): Mark locals as initialized.
7663 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7665 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7667 * search.c (Fre_search_backward): Mention `case-fold-search' in
7668 all the re_search_* functions (bug#8138).
7670 * keyboard.c (Fopen_dribble_file): Document when the file is
7673 2011-07-14 Eli Zaretskii <eliz@gnu.org>
7675 * bidi.c (bidi_dump_cached_states): Fix format of displaying
7678 Support bidi reordering of display and overlay strings.
7679 * xdisp.c (compute_display_string_pos)
7680 (compute_display_string_end): Accept additional argument STRING.
7681 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
7682 (reseat_to_string): Initialize bidi_it->string.s and
7683 bidi_it->string.schars.
7684 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
7685 NULL (avoids a crash in bidi_paragraph_init).
7686 Initialize itb.string.lstring.
7687 (init_iterator): Call bidi_init_it only of a valid
7688 buffer position was specified. Initialize paragraph_embedding to
7690 (reseat_to_string): Initialize the bidi iterator.
7691 (display_string): If we need to ignore text properties of
7692 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7693 original value of -1 will not work with bidi.)
7694 (compute_display_string_pos): First arg is now struct
7695 `text_pos *'; all callers changed. Support display properties on
7697 (compute_display_string_end): Support display properties on Lisp
7699 (init_iterator, reseat_1, reseat_to_string): Initialize the
7700 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7701 when iterating on a string not from display properties).
7702 (compute_display_string_pos, compute_display_string_end):
7703 Fix calculation of the object to scan. Fixes an error when using
7705 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7706 base_level_stop; instead, set base_level_stop to BEGV.
7707 Fixes crashes in vertical-motion.
7708 (next_element_from_buffer): Improve commentary for when
7709 the iterator is before prev_stop.
7710 (init_iterator): Initialize bidi_p from the default value of
7711 bidi-display-reordering, not from buffer-local value. Use the
7712 buffer-local value only if initializing for buffer iteration.
7713 (handle_invisible_prop): Support invisible properties on strings
7714 that are being bidi-reordered.
7715 (set_iterator_to_next): Support bidi reordering of C strings and
7717 (next_element_from_string): Support bidi reordering of Lisp
7719 (handle_stop_backwards): Support Lisp strings as well.
7720 (display_string): Support display of R2L glyph rows.
7721 Use IT_STRING_CHARPOS when displaying from a Lisp string.
7722 (init_iterator): Don't initialize it->bidi_p for strings
7724 (reseat_to_string): Initialize it->bidi_p for strings here.
7725 (next_element_from_string, next_element_from_c_string)
7726 (next_element_from_buffer): Add xassert's for correspondence
7727 between IT's object being iterated and it->bidi_it.string
7729 (face_before_or_after_it_pos): Support bidi iteration.
7730 (next_element_from_c_string): Handle the case of the first string
7731 character that is not the first one in the visual order.
7732 (get_visually_first_element): New function, refactored from common
7733 parts of next_element_from_buffer, next_element_from_string, and
7734 next_element_from_c_string.
7735 (tool_bar_lines_needed, redisplay_tool_bar)
7736 (display_menu_bar): Force left-to-right direction. Add a FIXME
7737 comment for making that be controlled by a user option.
7738 (push_it, pop_it): Save and restore the state of the
7739 bidi iterator. Save and restore the bidi_p flag.
7740 (pop_it): Iterate out of display property for string iteration as
7742 (iterate_out_of_display_property): Support iteration over strings.
7743 (handle_single_display_spec): Set up it->bidi_it for iteration
7744 over a display string, and call bidi_init_it.
7745 (handle_single_display_spec, next_overlay_string)
7746 (get_overlay_strings_1, push_display_prop): Set up the bidi
7747 iterator for displaying display or overlay strings.
7748 (forward_to_next_line_start): Don't use the shortcut if
7750 (back_to_previous_visible_line_start): If handle_display_prop
7751 pushed the iterator stack, restore the internal state of the bidi
7752 iterator by calling bidi_pop_it same number of times.
7753 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
7754 and we are bidi-iterating, don't decrement the iterator position;
7755 instead, set the first_elt flag in the bidi iterator, to produce
7757 (reseat_1): Remove redundant setting of string_from_display_prop_p.
7758 (push_display_prop): xassert that we are iterating a buffer.
7759 (push_it, pop_it): Save and restore paragraph_embedding member.
7760 (handle_single_display_spec, next_overlay_string)
7761 (get_overlay_strings_1, reseat_1, reseat_to_string)
7762 (push_display_prop): Set up the `unibyte' member of bidi_it.string
7763 correctly. Don't assume unibyte strings are not bidi-reordered.
7764 (compute_display_string_pos)
7765 (compute_display_string_end): Fix handling the case of C string.
7766 (push_it, pop_it): Save and restore from_disp_prop_p.
7767 (handle_single_display_spec, push_display_prop): Set the
7768 from_disp_prop_p flag.
7769 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
7770 (pop_it): Call iterate_out_of_display_property only if we are
7771 popping after iteration over a string that came from a display
7772 property. Fix a typo in popping stretch info. Add an assertion
7773 for verifying that the iterator position is in sync with the bidi
7775 (handle_single_display_spec, get_overlay_strings_1)
7776 (push_display_prop): Fix initialization of paragraph direction for
7777 string when that of the parent object is not yet determined.
7778 (reseat_1): Call bidi_init_it to resync the bidi
7779 iterator with IT's position. (Bug#7616)
7780 (find_row_edges): If ROW->start.pos gives position
7781 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
7782 (handle_stop, back_to_previous_visible_line_start, reseat_1):
7783 Reset the from_disp_prop_p flag.
7784 (SAVE_IT, RESTORE_IT): New macros.

7789 (try_scrolling, redisplay_window, display_line): Use them when
7790 saving a temporary copy of the iterator and restoring it back.
7791 (back_to_previous_visible_line_start, reseat_1)
7792 (init_iterator): Empty the bidi cache "stack".
7793 (move_it_in_display_line_to): If iterator ended up at
7794 EOL, but we never saw any buffer positions smaller than
7795 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor

8228 Random fixes. E.g., (random) never returned negative values.
8229 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8230 subseconds part to the entropy, as that's a bit more random.
8231 Prefer signed to unsigned, since the signedness doesn't matter and
8232 in general we prefer signed. When given a limit, use a
8233 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8234 latter isn't right if USE_2_TAGS_FOR_INTS.
8235 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8236 not 0..VALMASK. Don't discard "excess" bits that random () returns.

8260 error be more correct.
8262 * fns.c (Frequire): Remove the mention of the .gz files, since
8263 that's installation-specific, but keep the mention of
8264 `get-load-suffixes'.

8381 * eval.c (struct backtrace): Simplify and port the data structure.
8382 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8383 signed bit field, as this assumption is not portable and it makes
8384 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8385 "char debug_on_exit : 1" as this is not portable either; instead,
8386 use the portable "unsigned int debug_on_exit : 1". Remove unused
8387 member evalargs. Remove obsolete comments about cc bombing out.

8557 Don't set size unless allocation succeeds.
8559 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
8560 for sizes. Check for string overflow more accurately.

8621 (debug_method_add): Use va_list and vsprintf rather than relying
8622 on undefined behavior with wrong number of arguments.
8623 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8624 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8625 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8626 since we're not interested in debugging glyphs with old libraries.
8627 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8628 GCC 4.6.0's static checking.
8630 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

8670 (x_session_initialize): Do not assume string length fits in int.
8672 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

8713 * filelock.c: Fix some buffer overrun and integer overflow issues.
8714 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8715 Reformulate so as not to need the command string.
8716 Invoke gzip -cd rather than gunzip, as it's more portable.
8717 (lock_info_type, lock_file_1, lock_file):
8718 Don't assume pid_t and time_t fit in unsigned long.
8719 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8720 (current_lock_owner): Prefer signed type for sizes.
8721 Use memcpy, not strncpy, where memcpy is what is really wanted.
8722 Don't assume (via atoi) that time_t and pid_t fit in int.
8723 Check for time_t and/or pid_t out of range, e.g., via a network share.
8724 Don't alloca where an auto var works fine.
8726 * fileio.c: Fix some integer overflow issues.
8727 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8728 Don't assume string length fits in int.
8729 (directory_file_name): Don't assume string length fits in long.
8730 (make_temp_name): Don't assume pid fits in int, or that its print
8731 length is less than 20.
8733 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8735 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8737 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
8739 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
8740 We prefer signed integers, even for size calculations.
8742 * emacs.c: Don't assume string length fits in 'int'.
8743 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
8744 (main): Don't invoke strlen when not needed.
8746 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
8747 (XD_DEBUG_MESSAGE): Don't waste a byte.
8749 * callproc.c (getenv_internal_1, getenv_internal)
8751 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8753 * lread.c (invalid_syntax): Omit length argument.
8754 All uses changed. This doesn't fix a bug, but it simplifies the
8755 code away from its former Hollerith-constant appearance, and it's
8756 one less 'int' to worry about when looking at integer-overflow issues.
8757 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8759 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8760 This didn't break anything, but it didn't help either.
8761 It's confusing to put a bogus integer in a place where the actual
8762 value does not matter.
8763 (LIST_END_P): Remove unused macro and its bogus comment.
8764 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8766 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8767 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8769 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8770 We prefer signed types, and the value cannot exceed the EMACS_INT
8771 range anyway (because otherwise the length would not be representable).
8772 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8773 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8774 This avoids a GCC warning when WIDE_EMACS_INT.
8776 * indent.c (sane_tab_width): New function.
8777 (current_column, scan_for_column, Findent_to, position_indentation)
8778 (compute_motion): Use it. This is just for clarity.
8779 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8781 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8783 * lisp.h (lint_assume): New macro.
8784 * composite.c (composition_gstring_put_cache):
8785 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8787 * editfns.c, insdel.c:
8788 Omit unnecessary forward decls, to simplify future changes.
8790 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8792 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8794 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8795 Use much-faster test for byte-length change.
8796 Don't assume string byte-length fits in 'int'.
8797 Check that character arg fits in 'int'.
8798 (mapcar1): Declare byte as byte, for clarity.
8800 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8802 * fns.c (concat): Catch string overflow earlier.
8803 Do not rely on integer wraparound.
8805 * dispextern.h (struct it.overlay_strings_charpos)
8806 (struct it.selective): Now EMACS_INT, not int.
8807 * xdisp.c (forward_to_next_line_start)
8808 (back_to_previous_visible_line_start)
8809 (reseat_at_next_visible_line_start, next_element_from_buffer):
8810 Don't arbitrarily truncate the value of 'selective' to int.
8812 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8814 * composite.c: Don't truncate sizes to 'int'.
8815 (composition_gstring_p, composition_reseat_it)
8816 (composition_adjust_point): Use EMACS_INT, not int.
8817 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8818 not EMACS_UINT, for indexes.
8820 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8822 * buffer.c: Include <verify.h>.
8823 (struct sortvec.priority, struct sortstr.priority):
8824 Now EMACS_INT, not int.
8825 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8826 (struct sortstr.size, record_overlay_string)
8827 (struct sortstrlist.size, struct sortlist.used):
8828 Don't truncate size to int.
8829 (record_overlay_string): Check for size-calculation overflow.
8830 (init_buffer_once): Check at compile-time, not run-time.
8832 2011-06-22 Jim Meyering <meyering@redhat.com>
8834 Don't leak an XBM-image-sized buffer
8835 * image.c (xbm_load): Free the image buffer after using it.
8837 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
8840 * composite.c (find_automatic_composition): Omit needless 'return 0;'
8841 that Sun C diagnosed.
8842 * fns.c (secure_hash): Fix pointer signedness issue.
8843 * intervals.c (static_offset_intervals): New function.
8844 (offset_intervals): Use it.
8846 2011-06-21 Leo Liu <sdl.web@gmail.com>
8849 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
8852 * fns.c (secure_hash): Rename from crypto_hash_function and change
8853 the first arg to accept symbols.
8854 (Fsecure_hash): New primitive.
8855 (syms_of_fns): New symbols.
8857 2011-06-20 Deniz Dogan <deniz@dogan.se>
8859 * process.c (Fset_process_buffer): Clarify return value in
8862 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
8864 * dispnew.c (add_window_display_history): Use BVAR.
8866 * xdisp.c (debug_method_add): Use BVAR.
8867 (check_window_end, dump_glyph_matrix, dump_glyph)
8868 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
8870 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
8873 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
8874 check till after the cache is created in init_frame_faces.
8876 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
8878 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
8880 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
8882 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8883 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8884 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8886 Improve buffer-overflow checking (Bug#8873).
8887 * fileio.c (Finsert_file_contents):
8888 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8889 Remove the old (too-loose) buffer overflow checks.
8890 They weren't needed, since make_gap checks for buffer overflow.
8891 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8892 The old code merely checked for Emacs fixnum overflow, and relied
8893 on undefined (wraparound) behavior. The new code avoids undefined
8894 behavior, and also checks for ptrdiff_t and/or size_t overflow.
8896 * editfns.c (Finsert_char): Don't dump core with very negative counts.
8897 Tune. Don't use wider integers than needed. Don't use alloca.
8898 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
8900 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8902 * insdel.c, lisp.h (buffer_overflow): New function.
8903 (insert_from_buffer_1, replace_range, replace_range_2):
8904 * insdel.c (make_gap_larger):
8905 * editfns.c (Finsert_char):
8906 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8908 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
8910 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
8912 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
8914 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
8915 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
8917 * fileio.c: Don't assume EMACS_INT fits in off_t.
8918 (emacs_lseek): New static function.
8919 (Finsert_file_contents, Fwrite_region): Use it.
8920 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
8922 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
8924 * fns.c: Don't overflow int when computing a list length.
8925 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
8926 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
8927 truncation on 64-bit hosts. Check for QUIT every
8928 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
8929 faster and is responsive enough.
8930 (Flength): Report an error instead of overflowing an integer.
8931 (Fsafe_length): Return a float if the value is not representable
8932 as a fixnum. This shouldn't happen except in contrived situations.
8933 (Fnthcdr, Fsort): Don't assume list length fits in int.
8934 (Fcopy_sequence): Don't assume vector length fits in int.
8936 * alloc.c: Check that resized vectors' lengths fit in fixnums.
8937 (header_size, word_size): New constants.
8938 (allocate_vectorlike): Don't check size overflow here.
8939 (allocate_vector): Check it here instead, since this is the only
8940 caller of allocate_vectorlike that could cause overflow.
8941 Check that the new vector's length is representable as a fixnum.
8943 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
8944 The previous code was bogus. For example, next_almost_prime (32)
8945 returned 39, which is undesirable as it is a multiple of 3; and
8946 next_almost_prime (24) returned 25, which is a multiple of 5 so
8947 why was the code bothering to check for multiples of 7?
8949 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
8951 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
8953 Variadic C functions now count arguments with ptrdiff_t.
8954 This partly undoes my 2011-03-30 change, which replaced int with size_t.
8955 Back then I didn't know that the Emacs coding style prefers signed int.
8956 Also, in the meantime I found a few more instances where arguments
8957 were being counted with int, which may truncate counts on 64-bit
8958 machines, or EMACS_INT, which may be unnecessarily wide.
8959 * lisp.h (struct Lisp_Subr.function.aMANY)
8960 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
8961 Arg counts are now ptrdiff_t, not size_t.
8962 All variadic functions and their callers changed accordingly.
8963 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
8964 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
8965 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
8966 * callint.c (Fcall_interactively): Check arg count for overflow,
8967 to avoid potential buffer overrun. Use signed char, not 'int',
8968 for 'varies' array, so that we needn't bother to check its size
8969 calculation for overflow.
8970 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
8971 * eval.c (apply_lambda):
8972 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
8973 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
8974 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
8976 * callint.c (Fcall_interactively): Don't use index var as event count.
8978 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
8979 * mem-limits.h (SIZE): Remove; no longer used.
8981 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
8983 Remove unnecessary casts.
8984 * xterm.c (x_term_init):
8985 * xfns.c (x_set_border_pixel):
8986 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
8987 These aren't needed now that we assume ANSI C.
8989 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
8990 It's more likely to cause problems (due to unsigned overflow)
8993 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
8995 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
8997 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
8999 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9001 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9003 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9005 GLYPH_CODE_FACE returns EMACS_INT, not int.
9006 * dispextern.h (merge_faces):
9007 * xfaces.c (merge_faces):
9008 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9009 Don't assume EMACS_INT fits in int.
9011 * character.h (CHAR_VALID_P): Remove unused parameter.
9012 * fontset.c, lisp.h, xdisp.c: All uses changed.
9014 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9016 * fns.c (concat): Minor tuning based on overflow analysis.
9017 This doesn't fix any bugs. Use int to hold character, instead
9018 of constantly refetching from Emacs object. Use XFASTINT, not
9019 XINT, for value known to be a character. Don't bother comparing
9020 a single byte to 0400, as it's always less.
9022 * floatfns.c (Fexpt):
9023 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9025 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9028 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9030 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9031 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9032 incorrectly succeed when S was a string, because 4294967386 was
9033 truncated before it was used.
9035 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9036 Otherwise, an out-of-range integer could cause undefined behavior
9039 * composite.c: Use int, not EMACS_INT, for characters.
9040 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9041 EMACS_INT, for values that are known to be in character range.
9042 This doesn't fix any bugs but is the usual style inside Emacs and
9043 may generate better code on 32-bit machines.
9045 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9046 This is for reasons similar to the recent CHAR_STRING fix.
9047 * charset.c (Fencode_char): Check that character arg is actually
9048 a character. Pass an int to ENCODE_CHAR.
9049 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9050 wider than 'int', as a compile-time check to prevent future regressions
9053 * character.c (char_string): Remove unnecessary casts.
9055 Make sure a 64-bit char is never passed to CHAR_STRING.
9056 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9057 by silently ignoring the top 32 bits, allowing some values
9058 that were far too large to be valid characters.
9059 * character.h: Include <verify.h>.
9060 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9061 arguments are no wider than unsigned, as a compile-time check
9062 to prevent future regressions in this area.
9064 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9065 (Fsubst_char_in_region):
9067 * xdisp.c (decode_mode_spec_coding):
9068 Adjust to CHAR_STRING's new requirement.
9069 * editfns.c (Finsert_char, Fsubst_char_in_region):
9070 * fns.c (concat): Check that character args are actually
9071 characters. Without this test, these functions did the wrong
9072 thing with wildly out-of-range values on 64-bit hosts.
9074 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9075 These casts should not be needed on 32-bit hosts, either.
9076 * keyboard.c (read_char):
9077 * lread.c (Fload): Remove casts to unsigned.
9079 * lisp.h (UNSIGNED_CMP): New macro.
9080 This fixes comparison bugs on 64-bit hosts.
9081 (ASCII_CHAR_P): Use it.
9082 * casefiddle.c (casify_object):
9083 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9084 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9085 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9086 * dispextern.h (FACE_FROM_ID):
9087 * keyboard.c (read_char): Use UNSIGNED_CMP.
9089 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9090 not to EMACS_INT, to avoid GCC warning.
9092 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9094 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9095 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9096 isn't needed on 32-bit machines.
9098 * buffer.c (Fgenerate_new_buffer_name):
9099 Use EMACS_INT for count, not int.
9100 (advance_to_char_boundary): Return EMACS_INT, not int.
9102 * data.c (Qcompiled_function): Now static.
9104 * window.c (window_body_lines): Now static.
9106 * image.c (gif_load): Rename local to avoid shadowing.
9108 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9109 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9110 * alloc.c (make_save_value): Integer argument is now of type
9112 (mark_object): Use ptrdiff_t, not int.
9113 * lisp.h (pD): New macro.
9114 * print.c (print_object): Use it.
9116 * alloc.c: Use EMACS_INT, not int, to count objects.
9117 (total_conses, total_markers, total_symbols, total_vector_size)
9118 (total_free_conses, total_free_markers, total_free_symbols)
9119 (total_free_floats, total_floats, total_free_intervals)
9120 (total_intervals, total_strings, total_free_strings):
9121 Now EMACS_INT, not int. All uses changed.
9122 (Fgarbage_collect): Compute overall total using a double, so that
9123 integer overflow is less likely to be a problem. Check for overflow
9124 when converting back to an integer.
9125 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9126 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9127 These were 'int' variables that could overflow on 64-bit hosts;
9128 they were never used, so remove them instead of repairing them.
9129 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9130 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9131 Previously, this ceilinged at INT_MAX, but that doesn't work on
9133 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9135 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9136 (allocate_vectorlike): Check for ptrdiff_t overflow.
9137 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9138 when a (possibly-narrower) signed value would do just as well.
9139 We prefer using signed arithmetic, to avoid comparison confusion.
9141 * alloc.c: Catch some string size overflows that we were missing.
9142 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9143 for convenience in STRING_BYTES_MAX.
9144 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9145 The definition here is exact; the one in lisp.h was approximate.
9146 (allocate_string_data): Check for string overflow. This catches
9147 some instances we weren't catching before. Also, it catches
9148 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9149 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9150 and ptrdiff_t and EMACS_INT are both 64 bits.
9152 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9153 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9154 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9156 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9158 * alloc.c (Fmake_string): Check for out-of-range init.
9160 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9162 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9164 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
9166 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
9167 xg_get_default_scrollbar_width.
9169 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
9170 (int_gtk_range_get_value): Move to the scroll bar part of the file.
9171 (style_changed_cb): Call update_theme_scrollbar_width and call

9646 (Fframe_root_window, Fframe_first_window)
9647 (Fframe_selected_window): Move here from frame.c. Accept frame
9648 or arbitrary window as argument. Update doc-strings.
9649 (Fminibuffer_window): Move up in code.
9650 (Fwindow_minibuffer_p): Move up in code and simplify.
9651 (Fset_frame_selected_window): Move here from frame.c.
9653 (Fselected_window, select_window, Fselect_window): Move up in
9654 code. Minor doc-string fixes.

9658 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
9659 Do not assume that spare memory exists; that assumption is valid
9660 only if SYSTEM_MALLOC.
9661 (LARGE_REQUEST): New macro, so that the issue of large requests
9662 is separated from the issue of spare memory.
9664 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
9666 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

9681 min width by calling x_set_scroll_bar_default_width (Bug#8505).
9683 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
9685 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
9687 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

9691 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
9693 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
9694 Obey Vx_select_enable_clipboard_manager. Catch errors in
9695 x_clipboard_manager_save (Bug#8779).
9696 (Vx_select_enable_clipboard_manager): New variable.
9697 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
9699 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
9701 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
9703 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9705 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
9706 in the current matrix if keep_current_p is non-zero.

9710 * bidi.c (bidi_level_of_next_char): Fix last change.
9712 2011-06-03 Eli Zaretskii <eliz@gnu.org>
9714 Support bidi reordering of text covered by display properties.
9716 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
9717 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
9718 (bidi_cache_search, bidi_cache_iterator_state)
9719 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9720 (bidi_level_of_next_char, bidi_move_to_visually_next):
9721 Support character positions inside a run of characters covered by a
9723 (bidi_paragraph_init, bidi_resolve_explicit_1)
9724 (bidi_level_of_next_char): Call bidi_fetch_char and
9725 bidi_fetch_char_advance instead of FETCH_CHAR and
9727 (bidi_init_it): Initialize new members.
9728 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
9730 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
9731 instead of using explicit *_CHAR codes.
9732 (bidi_resolve_explicit, bidi_resolve_weak):
9733 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
9734 bidirectional text is supported only in multibyte buffers.
9735 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
9736 it to initialize the frame_window_p member of struct bidi_it.
9737 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
9738 (bidi_resolve_explicit, bidi_resolve_weak)
9739 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
9740 bidi_it->nchars is non-positive.
9741 (bidi_level_of_next_char): Don't try to lookup the cache for the
9742 next/previous character if nothing is cached there yet, or if we
9743 were just reseat()'ed to a new position.
9745 * xdisp.c (set_cursor_from_row): Set start and stop points
9746 according to the row's direction when priming the loop that looks
9747 for the glyph on which to display cursor.
9748 (single_display_spec_intangible_p): Function deleted.
9749 (display_prop_intangible_p): Reimplement to call
9750 handle_display_spec instead of single_display_spec_intangible_p.
9751 Accept 3 additional arguments needed by handle_display_spec.
9752 This fixes incorrect cursor motion across display property with complex
9753 values: lists, `(when COND...)' forms, etc.
9754 (single_display_spec_string_p): Support property values that are
9755 lists with the argument STRING its top-level element.
9756 (display_prop_string_p): Fix the condition for processing a
9757 property that is a list to be consistent with handle_display_spec.
9758 (handle_display_spec): New function, refactored from the
9759 last portion of handle_display_prop.
9760 (compute_display_string_pos): Accept additional argument
9761 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
9762 value of a `display' property is a "replacing spec".
9763 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
9764 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
9765 the display property, but just return a value indicating whether
9766 the display property will replace the characters it covers.
9767 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
9768 frame_window_p members of struct bidi_it.
9769 (compute_display_string_pos, compute_display_string_end):
9771 (push_it): Accept second argument POSITION, where pop_it should
9772 jump to continue iteration.
9773 (reseat_1): Initialize bidi_it.disp_pos.
9775 * keyboard.c (adjust_point_for_property): Adjust the call to
9776 display_prop_intangible_p to its new signature.
9778 * dispextern.h (struct bidi_it): New member frame_window_p.
9779 (bidi_init_it): Update prototypes.
9780 (display_prop_intangible_p): Update prototype.
9781 (compute_display_string_pos, compute_display_string_end):
9783 (struct bidi_it): New members nchars and disp_pos. ch_len is now
9786 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
9788 Malloc failure behavior now depends on size of allocation.
9789 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
9790 * lisp.h: Change signatures accordingly.
9791 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
9792 All callers changed. (Bug#8762)
9794 * gnutls.c: Use Emacs's memory allocators.
9795 Without this change, the gnutls library would invoke malloc etc.
9796 directly, which causes problems on non-SYNC_INPUT hosts, and which
9797 runs afoul of improving memory_full behavior. (Bug#8761)
9798 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9799 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9800 xfree instead of the default malloc, realloc, free.
9801 (Fgnutls_boot): No need to check for memory allocation failure,
9802 since xmalloc does that for us.
9804 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
9805 * category.c (hash_get_category_set):
9806 * ccl.c (ccl_driver):
9807 * charset.c (Fdefine_charset_internal):
9808 * charset.h (struct charset.hash_index):

9817 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
9818 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
9819 (Fsxhash, Fgethash, Fputhash, Fmaphash):
9820 * image.c (make_image, search_image_cache, lookup_image)
9821 (xpm_put_color_table_h):
9822 * lisp.h (struct Lisp_Hash_Table):
9823 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
9824 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
9825 for hashes and hash indexes, instead of 'unsigned' and 'int'.
9826 * alloc.c (allocate_vectorlike):
9827 Check for overflow in vector size calculations.
9828 * ccl.c (ccl_driver):
9829 Check for overflow when converting EMACS_INT to int.
9830 * fns.c, image.c: Remove unnecessary static decls that would otherwise
9831 need to be updated by these changes.
9832 * fns.c (make_hash_table, maybe_resize_hash_table):
9833 Check for integer overflow with large hash tables.
9834 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9835 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9836 (SXHASH_REDUCE): New macro.
9837 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
9838 Use it instead of discarding useful hash info with large hash values.
9839 (sxhash_float): New function.
9840 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
9841 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
9842 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9843 Rewrite to use FIXNUM_BITS, as this simplifies things.
9844 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9845 Adjust signatures to match updated version of code.
9846 (consing_since_gc): Now EMACS_INT, since a single hash table can
9847 use more than INT_MAX bytes.
9849 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
9851 Make it possible to build with GCC-4.6+ -O2 -flto.
9853 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
9855 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
9857 * minibuf.c (get_minibuffer, read_minibuf_unwind):
9858 Call minibuffer-inactive-mode.
9860 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
9862 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
9863 Update dependencies.
9865 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9867 * data.c (init_data): Remove code for UTS, this system is not
9870 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9872 Don't force ./temacs to start in terminal mode.
9874 * frame.c (make_initial_frame): Initialize faces in all cases, not
9875 only when CANNOT_DUMP is defined.
9876 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
9878 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9880 * dispnew.c (add_window_display_history): Use const for the string
9881 pointer. Remove declaration, not needed.
9883 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9885 Use 'inline', not 'INLINE'.
9886 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
9887 * alloc.c, fontset.c (INLINE): Remove.
9888 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
9889 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
9890 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
9891 * gmalloc.c (register_heapinfo): Use inline unconditionally.
9892 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
9894 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9896 Make it possible to run ./temacs.
9898 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
9899 syms_of_callproc does the same thing. Remove test for
9900 "initialized", do it in the caller.
9901 * emacs.c (main): Avoid calling set_initial_environment when dumping.
9903 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
9905 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
9906 (read_minibuf): Use get_minibuffer.
9907 (syms_of_minibuf): Use DEFSYM.
9908 (Qmetadata): New var.
9909 * data.c (Qbuffer): Don't make it static.
9910 (syms_of_data): Use DEFSYM.
9912 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9914 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
9915 (CCL_CODE_MIN): New macro.
9917 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
9919 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
9921 * eval.c (Qdebug): Now static.
9922 * lisp.h (Qdebug): Remove decl. This reverts a part of the
9923 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
9924 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
9926 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9928 * image.c: Various fixes to ImageMagick code comments.
9929 (Fimagemagick_types): Doc fix.
9931 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
9933 Minor fixes prompted by GCC 4.6.0 warnings.
9935 * xselect.c (converted_selections, conversion_fail_tag): Now static.
9937 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
9938 (x_clipboard_manager_save_all): Move extern decl to ...
9939 * xterm.h: ... here, so that it can be checked for consistency.
9941 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9943 * xselect.c (x_clipboard_manager_save_frame)
9944 (x_clipboard_manager_save_all): New functions.
9945 (Fx_clipboard_manager_save): Lisp function deleted.
9947 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
9948 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
9950 * xterm.h: Update prototype.
9952 2011-05-28 William Xu <william.xwl@gmail.com>
9954 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
9957 2011-05-28 Jim Meyering <meyering@redhat.com>
9959 Avoid a sign-extension bug in crypto_hash_function.
9960 * fns.c (to_uchar): Define.
9961 (crypto_hash_function): Use it to convert some newly-signed
9962 variables to unsigned, to avoid sign-extension bugs. For example,
9963 without this change, (md5 "truc") would evaluate to
9964 45723a2aff78ff4fff7fff1114760e62 rather than the expected
9965 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
9966 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
9968 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9970 Integer overflow fixes.
9972 * dbusbind.c: Serial number integer overflow fixes.
9973 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
9974 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
9975 to hold a serial number that is too large for a fixnum.
9976 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9977 Check for serial numbers out of range. Decode any serial number
9978 that was so large that it became a float. (Bug#8722)
9980 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
9981 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9982 Use XFASTINT rather than XUINT when numbers are nonnegative.
9983 (xd_append_arg, Fdbus_method_return_internal):
9984 (Fdbus_method_error_internal): Likewise. Also, for unsigned
9985 arguments, check that Lisp number is nonnegative, rather than
9986 silently wrapping negative numbers around. (Bug#8722)
9987 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
9990 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
9992 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
9994 ccl: Add integer overflow checks.
9995 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
9996 (IN_INT_RANGE): New macros.
9997 (ccl_driver): Use them to check for integer overflow when
9998 decoding a CCL program. Many of the new checks are whether XINT (x)
9999 fits in int; it doesn't always, on 64-bit hosts. The new version
10000 doesn't catch all possible integer overflows, but it's an
10001 improvement. (Bug#8719)
10003 * alloc.c (make_event_array): Use XINT, not XUINT.
10004 There's no need for unsigned here.
10006 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10007 This follows up to the 2011-05-06 change that substituted uintptr_t
10008 for EMACS_INT. This case wasn't caught back then.
10010 Rework Fformat to avoid integer overflow issues.
10011 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10012 now (part of C89). Include <verify.h>.
10013 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10014 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10015 (Fformat): Avoid the prepass trying to compute sizes; it was only
10016 approximate and thus did not catch overflow reliably. Instead, walk
10017 through the format just once, formatting and computing sizes as we go,
10018 checking for integer overflow at every step, and allocating a larger
10019 buffer as needed. Keep track separately whether the format is
10020 multibyte. Keep only the most-recently calculated precision, rather
10021 than them all. Record whether each argument has been converted to
10022 string. Use EMACS_INT, not int, for byte and char and arg counts.
10023 Support field widths and precisions larger than INT_MAX. Avoid
10024 sprintf's undefined behavior with conversion specifications such as %#d
10025 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10026 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10027 formatting out-of-range floating point numbers with int
10028 formats. (Bug#8668)
10030 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10032 * data.c: Avoid integer truncation in expressions involving floats.
10033 * data.c: Include <intprops.h>.
10034 (arith_driver): When there's an integer overflow in an expression
10035 involving floating point, convert the integers to floating point
10036 so that the resulting value does not suffer from catastrophic
10037 integer truncation. For example, on a 64-bit host (* 4
10038 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10039 Do not rely on undefined behavior after integer overflow.
10041 merge count_size_as_multibyte, parse_str_to_multibyte
10042 * character.c, character.h (count_size_as_multibyte):
10043 Rename from parse_str_to_multibyte; all uses changed.
10044 Check for integer overflow.
10045 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10046 since it's now a duplicate of the other. This is more of
10047 a character than a buffer op, so better that it's in character.c.
10048 * fns.c, print.c: Adjust to above changes.
10050 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10052 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10054 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10056 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10057 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10058 (x_clipboard_manager_save): Now static.
10059 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10061 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10062 (crypto_hash_function): Now static.
10063 Fix pointer signedness problems. Avoid unnecessary initializations.
10065 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10067 * termhooks.h (Vselection_alist): Make it terminal-local.
10069 * terminal.c (create_terminal): Initialize it.
10071 * xselect.c: Support for clipboard managers.
10072 (Vselection_alist): Move to termhooks.h as terminal-local var.
10073 (LOCAL_SELECTION): New macro.
10074 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10075 (symbol_to_x_atom): Remove gratuitous arg.
10076 (x_handle_selection_request, lisp_data_to_selection_data)
10077 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10078 (x_own_selection, x_get_local_selection, x_convert_selection):
10079 New arg, specifying work frame. Use terminal-local Vselection_alist.
10080 (some_frame_on_display): Delete unused function.
10081 (Fx_own_selection_internal, Fx_get_selection_internal)
10082 (Fx_disown_selection_internal, Fx_selection_owner_p)
10083 (Fx_selection_exists_p): New optional frame arg.
10084 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10085 (x_handle_selection_clear): Don't treat other terminals with the
10086 same keyboard specially. Use the terminal-local Vselection_alist.
10087 (x_clear_frame_selections): Use Frun_hook_with_args.
10089 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10091 * xterm.h: Add support for those atoms.
10093 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10095 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10096 (converted_selections, conversion_fail_tag): New global variables.
10097 (x_selection_request_lisp_error): Free the above.
10098 (x_get_local_selection): Remove unnecessary code.
10099 (x_reply_selection_request): Args changed; handle arbitrary array
10100 of converted selections stored in converted_selections.
10101 Separate the XChangeProperty and SelectionNotify steps.
10102 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10103 (x_convert_selection): New function.
10104 (x_handle_selection_event): Simplify.
10105 (x_get_foreign_selection): Don't ignore incoming requests while
10106 waiting for an answer; this will fail when we implement
10107 SAVE_TARGETS, and seems unnecessary anyway.
10108 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10109 (Vx_sent_selection_functions): Doc fix.
10111 2011-05-26 Leo Liu <sdl.web@gmail.com>
10113 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10115 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10117 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10119 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10120 for fringe update if it has periodic bitmap.
10121 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10122 and fringe_bitmap_periodic_p.
10124 * fringe.c (get_fringe_bitmap_data): New function.
10125 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10126 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10127 row. Mark glyph row for fringe update if periodicity changed.
10129 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10130 for fringe update unless it has periodic bitmap.
10132 2011-05-25 Kenichi Handa <handa@m17n.org>
10134 * xdisp.c (get_next_display_element): Set correct it->face_id for
10135 a static composition.
10137 2011-05-24 Leo Liu <sdl.web@gmail.com>
10140 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10142 * fns.c (crypto_hash_function, Fsha1): New function.
10143 (Fmd5): Use crypto_hash_function.
10144 (syms_of_fns): Add Ssha1.
10146 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10148 * gnutls.c: Remove unused macros.
10149 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10150 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10151 Remove macros that are defined and never used.
10152 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10154 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10156 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10157 (Fx_get_selection_internal): Minor cleanup.
10158 (Fx_own_selection_internal): Rename arguments for consistency with
10161 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10163 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10165 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10167 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10169 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10171 * dispnew.c (scrolling_window): Don't exclude the case that the
10172 last enabled row in the desired matrix touches the bottom boundary.
10174 2011-05-21 Glenn Morris <rgm@gnu.org>
10176 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10177 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10178 and add some more files.
10180 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10182 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10183 report_file_error introduced by the change from 2011-05-07.
10185 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10187 * systime.h (Time): Define only if emacs is defined.
10188 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10189 where the include path doesn't have X11/X.h by default. See
10190 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10192 2011-05-20 Kenichi Handa <handa@m17n.org>
10194 * composite.c (find_automatic_composition): Fix previous change.
10196 2011-05-20 Glenn Morris <rgm@gnu.org>
10198 * lisp.mk: New file, split from Makefile.in.
10199 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10200 (shortlisp): Remove.
10201 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10203 2011-05-19 Glenn Morris <rgm@gnu.org>
10205 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10206 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10207 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10208 (lisp): Set the order to that of loadup.el.
10209 (shortlisp): Make it a copy of $lisp.
10210 (SOME_MACHINE_LISP): Remove.
10211 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10212 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10214 2011-05-18 Kenichi Handa <handa@m17n.org>
10216 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10217 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10218 (find_automatic_composition): Mostly rewrite for efficiency.
10220 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10222 * makefile.w32-in: Update dependencies.
10224 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10226 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10227 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10229 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10231 Fix some integer overflow issues, such as string length overflow.
10233 * insdel.c (count_size_as_multibyte): Check for string overflow.
10235 * character.c (lisp_string_width): Check for string overflow.
10236 Use EMACS_INT, not int, for string indexes and lengths; in
10237 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10238 the resulting string length overflows an EMACS_INT; instead,
10239 report a string overflow if no precision given. When checking for
10240 precision exhaustion, use a check that cannot possibly have
10241 integer overflow. (Bug#8675)
10242 * character.h (lisp_string_width): Adjust to new signature.
10244 * alloc.c (string_overflow): New function.
10245 (Fmake_string): Use it. This doesn't change behavior, but saves
10246 a few bytes and will simplify future changes.
10247 * character.c (string_escape_byte8): Likewise.
10248 * lisp.h (string_overflow): New decl.
10250 Fixups, following up to the user-interface timestamp change.
10251 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10252 for UI timestamps, instead of unsigned long.
10253 * msdos.c (mouse_get_pos): Likewise.
10254 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10255 * w32gui.h (Time): Define by including "systime.h" rather than by
10256 declaring it ourselves. (Bug#8664)
10258 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10259 * image.c (clear_image_cache): Likewise.
10261 * term.c (term_mouse_position): Don't assume time_t wraparound.
10263 Be more systematic about user-interface timestamps.
10264 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10265 and sometimes 'EMACS_UINT', to represent these timestamps.
10266 This change causes it to use 'Time' uniformly, as that's what X uses.
10267 This makes the code easier to follow, and makes it easier to catch
10268 integer overflow bugs such as Bug#8664.
10269 * frame.c (Fmouse_position, Fmouse_pixel_position):
10270 Use Time, not unsigned long, for user-interface timestamps.
10271 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10272 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10273 * keyboard.h (last_event_timestamp): Likewise.
10274 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10275 * menu.h (xmenu_show): Likewise.
10276 * term.c (term_mouse_position): Likewise.
10277 * termhooks.h (struct input_event.timestamp): Likewise.
10278 (struct terminal.mouse_position_hook): Likewise.
10279 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10280 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10281 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10282 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10283 what it was before.
10284 * menu.h, termhooks.h: Include "systime.h", for Time.
10286 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10287 Don't assume that the difference between two unsigned long values
10288 can fit into an integer. At this point, we know button_down_time
10289 <= event->timestamp, so the difference must be nonnegative, so
10290 there's no need to cast the result if double-click-time is
10291 nonnegative, as it should be; check that it's nonnegative, just in
10292 case. This bug is triggered when events are more than 2**31 ms
10293 apart (about 25 days). (Bug#8664)
10295 * xselect.c (last_event_timestamp): Remove duplicate decl.
10296 (x_own_selection): Remove needless cast to unsigned long.
10298 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10299 that always fit in int. Use a sentinel instead of a counter, to
10300 avoid a temp and to allay GCC's concerns about possible int overflow.
10301 * frame.h (struct frame): Use int for menu_bar_items_used
10302 instead of EMACS_INT, since it always fits in int.
10304 * menu.c (grow_menu_items): Check for int overflow.
10306 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10308 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10309 Before, the code was not consistent. These values cannot exceed
10310 2**31 - 1 so there's no need to make them unsigned.
10311 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10312 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10313 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10315 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10317 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10318 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10319 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10320 presumably because the widths might not match.
10322 * window.c (size_window): Avoid needless test at loop start.
10324 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10326 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10328 2011-05-12 Drew Adams <drew.adams@oracle.com>
10330 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10332 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10334 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10335 `width' to `bar_area_x' and `bar_area_width', respectively.
10336 (x_scroll_run): Take account of fringe background extension.
10338 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10339 Rename local vars `left' and `width' to `bar_area_x' and
10340 `bar_area_width', respectively.
10341 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10342 background extension.
10344 2011-05-10 Jim Meyering <meyering@redhat.com>
10346 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10348 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10350 * image.c (Finit_image_library): Return t for built-in image types,
10351 like pbm and xbm. (Bug#8640)
10353 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10355 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10357 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10359 * w32console.c (Fset_screen_color): Doc fix.
10360 (Fget_screen_color): New function.
10361 (syms_of_ntterm): Defsubr it.
10363 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10364 unlink the temporary file if Fcall_process didn't create it in the
10366 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10367 child process will be redirected to a file specified with `:file'.
10368 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10369 cue to call_process_cleanup not to close that handle.
10371 2011-05-07 Ben Key <bkey76@gmail.com>
10373 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10374 one of two shell specific rules, either bootstrap-temacs-CMD or
10375 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10376 to the previous implementation of the bootstrap-temacs rule.
10377 The bootstrap-temacs-CMD rule is similar to the previous
10378 implementation of the bootstrap-temacs rule except that it
10379 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10382 These changes, along with some changes to nt/configure.bat,
10383 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10384 earlier fix to add support for --cflags and --ldflags options
10385 that include quotes so that it works whether make uses cmd or
10388 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10390 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10391 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10393 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10394 a string. Handle both cases.
10395 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10396 (Fdbus_register_method): Use Qinvalid_function.
10398 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10400 * makefile.w32-in: Update dependencies.
10401 (LISP_H): Add inttypes.h and stdin.h.
10402 (PROCESS_H): Add unistd.h.
10404 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10406 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10407 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10409 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10411 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10413 * term.c (vfatal): Remove stray call to va_end.
10414 It's not needed and the C Standard doesn't allow it here anyway.
10416 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10417 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10419 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10422 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10424 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10426 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10428 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10430 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10432 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10433 * charset.c (Fdefine_charset_internal): Don't initialize
10434 charset.code_space[15]. The value was garbage, on hosts with
10435 32-bit int (Bug#8600).
10437 * lread.c (read_integer): Be more consistent with string-to-number.
10438 Use string_to_number to do the actual conversion; this avoids
10439 rounding errors and fixes some other screwups. Without this fix,
10440 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10441 (digit_to_number): Move earlier, for benefit of read_integer.
10442 Return -1 if the digit is out of range for the base, -2 if it is
10443 not a digit in any supported base. (Bug#8602)
10445 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10447 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10448 to match comment at start of function. This also removes a
10449 GCC warning about overflow in a 32+64-bit port.
10451 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10453 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10454 Reported by Stefan Monnier in
10455 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10456 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10457 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10459 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10460 (EMACS_UINTPTR): Likewise, with uintptr_t.
10462 * lisp.h: Prefer 64-bit EMACS_INT if available.
10463 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10464 on 32-bit hosts that have 64-bit int, so that they can access
10466 However, temporarily disable this change unless the temporary
10467 symbol WIDE_EMACS_INT is defined.
10469 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10471 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10472 This removes an assumption that EMACS_INT and long are the same
10473 width as pointers. The assumption is true for Emacs porting targets
10474 now, but we want to make other targets possible.
10475 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10476 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10477 In the rest of the code, change types of integers that hold casted
10478 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10479 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10480 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10481 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10482 No need to cast type when ORing.
10483 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10484 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10485 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10486 assume EMACS_INT is the same width as char *.
10487 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10488 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10489 Remove no-longer-needed casts.
10490 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10491 (xg_tool_bar_help_callback, xg_make_tool_item):
10492 Use EMACS_INTPTR to hold an integer
10493 that will be cast to void *; this can avoid a GCC warning
10494 if EMACS_INT is not the same width as void *.
10495 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10496 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10497 (current_message_1, set_message_1):
10498 Use a local to convert to proper width without a cast.
10499 * xmenu.c (dialog_selection_callback): Likewise.
10501 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10502 Also, don't assume VALBITS / RAND_BITS is less than 5,
10503 and don't rely on undefined behavior when shifting a 1 left into
10505 * lisp.h (get_random): Change signature to match.
10507 * lread.c (hash_string): Use size_t, not int, for hash computation.
10508 Normally we prefer signed values; but hashing is special, because
10509 it's better to use unsigned division on hash table sizes so that
10510 the remainder is nonnegative. Also, size_t is the natural width
10511 for hashing into memory. The previous code used 'int', which doesn't
10512 retain enough info to hash well into very large tables.
10513 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10515 * dbusbind.c: Don't possibly lose pointer info when converting.
10516 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10517 Use XPNTR rather than XHASH, so that the high-order bits of
10518 the pointer aren't lost when converting through void *.
10520 * eval.c (Fautoload): Don't double-shift a pointer.
10522 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

10605 * process.c: Include lisp.h before w32.h, not after.
10606 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10607 instead of gnutls_record_check_pending.
10609 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10611 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10613 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10614 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10617 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10619 * xterm.c (x_set_frame_alpha): Do not set property on anything

10659 rather than `XVECTOR (FOO)->size'.
10661 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10662 inttypes.h, as a gnulib replacement is used if it not available in
10665 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10667 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

10672 will grow beyond MOST_POSITIVE_FIXNUM.
10673 (decode_coding_emacs_mule): Abort if there isn't enough place in

10677 charbuf for the composition carryover bytes.
10679 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10681 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
10682 aborting when %lld or %lll format is passed.

10684 %llo or %llx format is passed. (Bug#8545)
10686 * window.c (window_scroll_line_based): Use a marker instead of
10687 simple variables to record original value of point. (Bug#7952)
10689 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10690 produced by %s or %c overflows available buffer space. (Bug#8545)
10692 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10694 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10695 (SIZE_MAX): Move defn after all includes, as they might #define it.
10697 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10699 * w32.c (init_environment): Warn about defaulting HOME to C:\.
10701 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10703 * keyboard.c (Qdelayed_warnings_hook): Define.
10704 (command_loop_1): Run `delayed-warnings-hook'
10705 if Vdelayed_warnings_list is non-nil.
10706 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
10707 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10709 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10711 * doprnt.c (doprnt): Don't return value smaller than the buffer
10712 size if the message was truncated. (Bug#8545).
10714 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10716 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
10717 (Fx_window_property): #if-0 the whole functions, not just the bodies.
10719 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10721 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
10723 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
10725 * makefile.w32-in: Update dependencies.
10727 2011-04-27 Eli Zaretskii <eliz@gnu.org>
10729 Improve `doprnt' and its usage. (Bug#8545)
10730 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10731 `format_end'. Remove support for %l as a conversion specifier.
10732 Don't use xrealloc. Improve diagnostics when the %l size modifier
10733 is used. Update the commentary.
10735 * eval.c (verror): Simplify calculation of size_t.
10737 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10740 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10742 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10745 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10747 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10748 This makes this file independent of the recent pseudovector change.
10750 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10752 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10754 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10755 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10756 Remove unused local.
10757 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10759 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10760 GCC 4.6.0 optimizes based on type-based alias analysis.
10761 For example, if b is of type struct buffer * and v of type struct
10762 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10763 != &v->size, and therefore "v->size = 1; b->size = 2; return
10764 v->size;" must therefore return 1. This assumption is incorrect
10765 for Emacs, since it type-puns struct Lisp_Vector * with many other
10766 types. To fix this problem, this patch adds a new type struct
10767 vectorlike_header that documents the constraints on layout of vectors
10768 and pseudovectors, and helps optimizing compilers not get fooled
10769 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10770 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10771 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10773 (XSETPVECTYPE): Rewrite in terms of new macro.
10774 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10775 This is a bit clearer, and further avoids the possibility of
10776 undesirable aliasing.
10777 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10778 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10779 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10780 since Lisp_Subr is a special case (no "next" field).
10781 (ASIZE): Now uses header.size rather than size.
10782 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10783 to avoid the hassle of writing XVECTOR (foo)->header.size.
10784 (struct vectorlike_header): New type.
10785 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10786 object, to help avoid aliasing.
10787 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10788 (SUBRP): Likewise, since Lisp_Subr is a special case.
10789 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10790 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10791 (struct Lisp_Hash_Table): Combine first two members into a single
10792 struct vectorlike_header member. All uses of "size" and "next" members
10793 changed to be "header.size" and "header.next".
10794 * buffer.h (struct buffer): Likewise.
10795 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10796 * frame.h (struct frame): Likewise.
10797 * process.h (struct Lisp_Process): Likewise.
10798 * termhooks.h (struct terminal): Likewise.
10799 * window.c (struct save_window_data, struct saved_window): Likewise.
10800 * window.h (struct window): Likewise.
10801 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10802 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10803 * buffer.c (init_buffer_once): Likewise.
10804 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10806 * process.c (Fformat_network_address): Use local var for size,
10809 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10811 Make the Lisp reader and string-to-float more consistent (Bug#8525)
10812 * data.c (atof): Remove decl; no longer used or needed.
10813 (digit_to_number): Move to lread.c.
10814 (Fstring_to_number): Use new string_to_number function, to be
10815 consistent with how the Lisp reader treats infinities and NaNs.
10816 Do not assume that floating-point numbers represent EMACS_INT
10817 without losing information; this is not true on most 64-bit hosts.
10818 Avoid double-rounding errors, by insisting on integers when
10819 parsing non-base-10 numbers, as the documentation specifies.
10820 * lisp.h (string_to_number): New decl, replacing ...
10821 (isfloat_string): Remove.
10822 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10823 (read1): Do not accept +. and -. as integers; this
10824 appears to have been a coding error. Similarly, do not accept
10825 strings like +-1e0 as floating point numbers. Do not report
10826 overflow for integer overflows unless the base is not 10 which
10827 means we have no simple and reliable way to continue.
10828 Break out the floating-point parsing into a new
10829 function string_to_number, so that Fstring_to_number parses
10830 floating point numbers consistently with the Lisp reader.
10831 (digit_to_number): Move here from data.c. Make it static inline.
10832 (E_CHAR, EXP_INT): Remove, replacing with ...
10833 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10834 (string_to_number): New function, replacing isfloat_string.
10835 This function checks for valid syntax and produces the resulting
10836 Lisp float number too. Rework it so that string-to-number
10837 no longer mishandles examples like "1.0e+". Use strtoumax,
10838 so that overflow for non-base-10 numbers is reported only when
10839 there's no portable and simple way to convert to floating point.
10841 * textprop.c (set_text_properties_1): Rewrite for clarity,
10842 and to avoid GCC warning about integer overflow.
10844 * intervals.h (struct interval): Use EMACS_INT for members
10845 where EMACS_UINT might cause problems. See
10846 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10847 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10848 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10850 (offset_intervals): Tell GCC not to worry about length overflow
10851 when negating a negative length.
10853 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10854 (overrun_check_free): Likewise.
10856 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10857 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10860 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10861 (gnutls_make_error): Rename local to avoid shadowing.
10862 (gnutls_emacs_global_deinit): ifdef out; not used.
10863 (Fgnutls_boot): Use const for pointer to readonly storage.
10864 Comment out unused local. Fix pointer signedness problems.
10866 * lread.c (openp): Don't stuff size_t into an 'int'.
10867 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10868 about possible signed overflow.
10870 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10871 (GDK_KEY_g): Don't define if already defined.
10872 (xg_prepare_tooltip): Avoid pointer signedness problem.
10873 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10875 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10876 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
10878 * xfns.c (Fx_window_property): Simplify a bit,
10879 to make a bit faster and to avoid GCC 4.6.0 warning.
10880 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10882 * fns.c (internal_equal): Don't assume size_t fits in int.
10884 * alloc.c (compact_small_strings): Tighten assertion a little.
10886 Replace pEd with more-general pI, and fix some printf arg casts.
10887 * lisp.h (pI): New macro, generalizing old pEd macro to other
10888 conversion specifiers. For example, use "...%"pI"d..." rather
10889 than "...%"pEd"...".
10890 (pEd): Remove. All uses replaced with similar uses of pI.
10891 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10892 * alloc.c (check_pure_size): Don't overflow by converting size to int.
10893 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10894 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10895 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10896 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10897 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10899 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10900 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10901 * print.c (safe_debug_print, print_object): Likewise.
10902 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10904 Use pI instead of if-then-else-abort. Use %p to avoid casts,
10905 avoiding the 0 flag, which is not portable.
10906 * process.c (Fmake_network_process): Use pI to avoid cast.
10907 * region-cache.c (pp_cache): Likewise.
10908 * xdisp.c (decode_mode_spec): Likewise.
10909 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
10910 behavior on 64-bit hosts with printf arg.
10911 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
10912 (x_stop_queuing_selection_requests): Likewise.
10913 (x_get_window_property): Don't truncate byte count to an 'int'
10916 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
10917 here, since it parses constructs like leading '-' and spaces,
10918 which are not wanted; and it overflows with large numbers.
10919 Instead, simply match F[0-9]+, which is what is wanted anyway.
10921 * alloc.c: Remove unportable assumptions about struct layout.
10922 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
10923 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
10924 (allocate_vectorlike, make_pure_vector): Use the new macros,
10925 plus offsetof, to remove unportable assumptions about struct layout.
10926 These assumptions hold on all porting targets that I know of, but
10927 they are not guaranteed, they're easy to remove, and removing them
10928 makes further changes easier.
10930 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".

11824 * xdisp.c (vmessage): Use a better test for character truncation.
11826 * charset.c (load_charset_map): <, not <=, for optimization,
11827 and to avoid potential problems with integer overflow.
11828 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11829 * casetab.c (set_identity, shuffle): Likewise.
11830 * editfns.c (Fformat): Likewise.
11831 * syntax.c (skip_chars): Likewise.
11833 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11834 This also lets GCC 4.6.0 generate slightly better loop code.
11836 * callint.c (Fcall_interactively): <, not <=, for optimization.
11837 (Fcall_interactively): Count the number of arguments produced,
11838 not the number of arguments given. This is simpler and lets GCC
11839 4.6.0 generate slightly better code.
11841 * ftfont.c: Distingish more carefully between FcChar8 and char.
11842 The previous code passed unsigned char * to a functions like
11843 strlen and xstrcasecmp that expect char *, which does not
11844 conform to the C standard.
11845 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11846 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11847 char * when the C standard requires it.
11849 * keyboard.c (read_char): Remove unused var.
11851 * eval.c: Port to Windows vsnprintf (Bug#8435).
11852 Include <limits.h>.
11853 (SIZE_MAX): Define if the headers do not.
11854 (verror): Do not give up if vsnprintf returns a negative count.
11855 Instead, grow the buffer. This ports to Windows vsnprintf, which
11856 does not conform to C99. Problem reported by Eli Zaretskii.
11857 Also, simplify the allocation scheme, by avoiding the need for
11858 calling realloc, and removing the ALLOCATED variable.
11860 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11862 Remove invocations of doprnt, as Emacs now uses vsnprintf.
11863 But keep the doprint source code for now, as we might revamp it
11864 and use it again (Bug#8435).
11865 * lisp.h (doprnt): Remove.
11866 * Makefile.in (base_obj): Remove doprnt.o.
11867 * deps.mk (doprnt.o): Remove.
11869 error: Print 32- and 64-bit integers portably (Bug#8435).
11870 Without this change, on typical 64-bit hosts error ("...%d...", N)
11871 was used to print both 32- and 64-bit integers N, which relied on
11872 undefined behavior.
11873 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11874 * lisp.h (error, verror): Mark as printf-like functions.
11875 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11876 Report overflow in size calculations when allocating printf buffer.
11877 Do not truncate output string at its first null byte.
11878 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11879 Truncate the output at a character boundary, since vsnprintf does not
11881 * charset.c (check_iso_charset_parameter): Convert internal
11882 character to string before calling 'error', since %c now has the
11884 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11885 overflow when computing char to be passed to 'error'. Do not
11886 pass Lisp_Object to 'error'; pass the integer instead.
11887 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11888 formatted with plain %d.
11890 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11892 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
11894 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
11896 * xterm.c (x_catch_errors): Remove duplicate declaration.
11898 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
11900 * xdisp.c, lisp.h (message_nolog): Remove; unused.
11902 2011-04-10 Jim Meyering <meyering@redhat.com>
11904 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11905 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11906 return ssize_t not "int", and use size_t as the buffer length.
11907 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11908 * gnutls.h: Update declarations.
11909 * process.c (read_process_output): Use ssize_t, to match.
11910 (send_process): Likewise.
11912 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11914 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
11916 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11918 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
11919 Use unsigned char, to match FcChar8 type definition.
11921 * xterm.c (handle_one_xevent):
11922 * xmenu.c (create_and_show_popup_menu):
11923 * xselect.c (x_decline_selection_request)
11924 (x_reply_selection_request): Avoid type-punned deref of X events.
11926 2011-04-09 Eli Zaretskii <eliz@gnu.org>
11928 Fix some uses of `int' instead of EMACS_INT.
11929 * search.c (string_match_1, fast_string_match)
11930 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
11931 (scan_buffer, find_next_newline_no_quit)
11932 (find_before_next_newline, search_command, Freplace_match)
11933 (Fmatch_data): Make some `int' variables be EMACS_INT.
11935 * xdisp.c (display_count_lines): 3rd argument and return value now
11936 EMACS_INT. All callers changed.
11937 (pint2hrstr): Last argument is now EMACS_INT.
11939 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
11940 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
11941 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
11942 (decode_coding_utf_16, decode_coding_emacs_mule)
11943 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
11944 (decode_coding_ccl, decode_coding_charset)
11945 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
11946 (decode_coding_iso_2022, decode_coding_emacs_mule)
11947 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
11948 <char_offset, last_offset>: Declare EMACS_INT.
11949 (encode_coding_utf_8, encode_coding_utf_16)
11950 (encode_coding_emacs_mule, encode_invocation_designation)
11951 (encode_designation_at_bol, encode_coding_iso_2022)
11952 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
11953 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
11955 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
11956 (encode_invocation_designation): Last argument P_NCHARS is now
11958 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
11959 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
11961 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
11964 * ccl.c (Fccl_execute_on_string): Declare some variables
11967 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
11969 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
11971 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
11973 * process.c (Fformat_network_address): Doc fix.
11975 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
11977 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
11979 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
11981 * keyboard.c (read_char): Call Lisp function help-form-show,
11982 instead of using internal_with_output_to_temp_buffer.
11983 (Qhelp_form_show): New var.
11984 (syms_of_keyboard): Use DEFSYM macro.
11986 * print.c (internal_with_output_to_temp_buffer): Function deleted.
11988 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
11990 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
11992 * process.c (Flist_processes): Remove to Lisp.
11993 (list_processes_1): Delete.
11995 2011-04-06 Eli Zaretskii <eliz@gnu.org>
11997 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
11999 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12001 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12003 Fix more problems found by GCC 4.6.0's static checks.
12005 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
12007 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12009 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12011 * xdisp.c (vmessage): Mark as a printf-like function.
12013 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
12015 * sound.c (sound_warning): Don't crash if arg contains a printf format.
12017 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
12018 printf-like functions.
12019 (tiff_load): Add casts to remove these marks before passing them
12020 to system-supplied API.
12022 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12024 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12025 This avoids several warnings with gcc -Wstrict-overflow.
12026 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12027 directly, rather than having caller test rule sign. This avoids
12028 some unnecessary tests.
12029 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12030 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12031 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12033 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12034 (xfont_open): Avoid unnecessary tests.
12036 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12038 * composite.h, composite.c (composition_gstring_put_cache):
12039 Use EMACS_INT, not int, for length.
12041 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12042 breaking out part of COMPOSITION_DECODE_RULE.
12043 (COMPOSITION_DECODE_RULE): Use it.
12044 * composite.c (get_composition_id): Remove unused local vars,
12045 by using the new macro.
12047 * textprop.c (set_text_properties_1): Change while to do-while,
12048 since the condition is always true at first.
12050 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12051 (interval_deletion_adjustment): Return unsigned value.
12054 * process.c (list_processes_1, create_pty, read_process_output):
12055 (exec_sentinel): Remove vars that were set but not used.
12056 (create_pty): Remove unnecessary "volatile"s.
12057 (Fnetwork_interface_info): Avoid possibility of int overflow.

12064 (update_syntax_table): Use unsigned instead of int.
12066 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12067 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12068 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12070 * print.c (print_error_message): Avoid int overflow.
12072 * font.c (font_list_entities): Redo for clarity,
12073 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12075 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12076 (font_score): Avoid potential overflow in diff calculation.
12078 * fns.c (substring_both): Remove var that is set but not used.
12079 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12081 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12083 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12084 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12085 can always succeed if overflow has undefined behavior.
12087 * search.c (boyer_moore, wordify): Remove vars set but not used.
12088 (wordify): Omit three unnecessary tests.
12090 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
12091 All callers changed. This avoids the need for an unused var.
12093 * casefiddle.c (casify_region): Remove var that is set but not used.
12095 * dired.c (file_name_completion): Remove var that is set but not used.
12097 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12099 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12100 (Finsert_file_contents): Remove unnecessary code checking fd.
12102 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12103 Check for integer overflow on size calculations.
12105 * buffer.c (Fprevious_overlay_change): Remove var that is set
12108 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12109 Remove vars that are set but not used.
12110 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12111 (timer_check_2): Mark vars as initialized.
12113 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12115 * image.c (lookup_image): Remove var that is set but not used.
12116 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12118 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12119 that are set but not used.
12121 * xfns.c (make_invisible_cursor): Don't return garbage
12122 if XCreateBitmapFromData fails (Bug#8410).
12124 * xselect.c (x_get_local_selection, x_handle_property_notify):
12125 Remove vars that are set but not used.
12127 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12128 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12130 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12131 Remove var that is set but not used.
12132 (scroll_bar_windows_size): Now size_t, not int.
12133 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12134 Check for overflow.
12136 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12137 (map_tty_color) [!defined MSDOS]: Likewise.
12139 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12141 * coding.c: Remove vars that are set but not used.
12142 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12143 All callers changed.
12144 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12145 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12146 (decode_coding_charset): Remove vars that are set but not used.
12148 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12149 that is set but not used.
12151 * print.c (print_object): Remove var that is set but not used.
12153 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12154 The gnulib version avoids calling malloc in the usual case,
12155 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12156 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12157 * filelock.c (current_lock_owner): Likewise.
12158 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12159 * sysdep.c: Include allocator.h, careadlinkat.h.
12160 (emacs_no_realloc_allocator): New static constant.
12161 (emacs_readlink): New function.
12162 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12163 ../lib/careadlinkat.h.
12165 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12167 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12168 first non-nil return value).
12170 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
12172 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
12173 if not defined (Bug#8403).
12175 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12177 * xdisp.c (display_count_lines): Remove parameter `start',
12178 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12179 (get_char_face_and_encoding): Remove parameter `multibyte_p',
12180 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12181 (fill_stretch_glyph_string): Remove parameters `row' and `area',
12182 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
12183 and thereabouts. All callers changed.
12184 (get_per_char_metric): Remove parameter `f', unused since
12185 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12187 2011-04-02 Jim Meyering <meyering@redhat.com>
12189 do not dereference NULL upon failed strdup
12190 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12191 (ns_get_family): Likewise.
12193 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12195 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12197 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12199 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12202 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12204 Add lexical binding.
12206 * window.c (Ftemp_output_buffer_show): New fun.
12207 (Fsave_window_excursion):
12208 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
12210 * lread.c (lisp_file_lexically_bound_p): New function.
12211 (Fload): Bind Qlexical_binding.
12212 (readevalloop): Remove `evalfun' arg.
12213 Bind Qinternal_interpreter_environment.
12214 (Feval_buffer): Bind Qlexical_binding.
12215 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12217 (syms_of_lread): Declare `lexical-binding'.
12219 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12221 * keyboard.c (eval_dyn): New fun.
12222 (menu_item_eval_property): Use it.
12224 * image.c (parse_image_spec): Use Ffunctionp.
12226 * fns.c (concat, mapcar1): Accept byte-code-functions.
12228 * eval.c (Fsetq): Handle lexical vars.
12229 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12230 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12231 (FletX, Flet): Obey lexical binding.
12232 (Fcommandp): Handle closures.
12233 (Feval): New `lexical' arg.
12234 (eval_sub): New function extracted from Feval. Use it almost
12235 everywhere where Feval was used. Look up vars in lexical env.
12237 (Ffunctionp): Move from subr.el.
12238 (Ffuncall): Handle closures.
12239 (apply_lambda): Remove `eval_flags'.
12240 (funcall_lambda): Handle closures and new byte-code-functions.
12241 (Fspecial_variable_p): New function.
12242 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12243 but without exporting it to Lisp.
12245 * doc.c (Fdocumentation, store_function_docstring):
12246 * data.c (Finteractive_form): Handle closures.
12248 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12251 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12253 (exec_byte_code): New function extracted from Fbyte_code to handle new
12254 calling convention for byte-code-functions. Add new byte-codes.
12256 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12258 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12260 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12262 * xdisp.c (redisplay_internal): Fix prototype.
12264 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12266 * xdisp.c (SCROLL_LIMIT): New macro.
12267 (try_scrolling): Use it when setting scroll_limit.
12268 Limit scrolling to 100 screen lines.
12269 (redisplay_window): Even when falling back on "recentering",
12270 position point in the window according to scroll-conservatively,
12271 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12273 (try_scrolling): When point is above the window, allow searching
12274 as far as scroll_max, or one screenful, to compute vertical
12275 distance from PT to the scroll margin position. This prevents
12276 try_scrolling from unnecessarily failing when
12277 scroll-conservatively is set to a value slightly larger than the
12278 window height. Clean up the case of PT below the margin at bottom
12279 of window: scroll_max can no longer be INT_MAX. When aggressive
12280 scrolling is in use, don't let point enter the opposite scroll
12281 margin as result of the scroll.
12282 (syms_of_xdisp) <scroll-conservatively>: Document the
12283 threshold of 100 lines for never-recentering scrolling.
12285 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12287 * dispextern.h (move_it_by_lines):
12288 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
12289 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
12290 (message_log_check_duplicate): Remove parameters `prev_bol' and
12291 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12292 (redisplay_internal): Remove parameter `preserve_echo_area',
12293 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12295 * indent.c (Fvertical_motion):
12296 * window.c (window_scroll_pixel_based, Frecenter):
12297 Don't pass `need_y_p' to `move_it_by_lines'.
12299 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12301 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12302 steal a few bits to be more compact.
12303 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12304 Remove unneeded casts.
12306 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12308 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12310 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12311 binding" message (bug#7967).
12313 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12315 Fix more problems found by GCC 4.6.0's static checks.
12317 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12318 Remove unused local var.
12320 * editfns.c (Fmessage_box): Remove unused local var.
12322 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12323 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12324 Omit unused local vars.
12325 * window.c (shrink_windows): Omit unused local var.
12326 * menu.c (digest_single_submenu): Omit unused local var.
12327 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12328 Omit unused local var.
12330 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12331 Don't assume string length fits in int.
12332 (keyremap_step, read_key_sequence): Use size_t for sizes.
12333 (read_key_sequence): Don't check last_real_key_start redundantly.
12335 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12336 instead of alloca (Bug#8344).
12338 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12339 (Fbacktrace_frame): Don't assume nframes fits in int.
12341 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12343 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12346 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12348 * cm.c (calccost): Turn while-do into do-while, for clarity.
12350 * keyboard.c (syms_of_keyboard): Use the same style as later
12351 in this function when indexing through an array. This also
12352 works around GCC bug 48267.
12354 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12356 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

12359 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12361 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12362 This avoids undefined behavior on integer overflow, and is a bit
12363 more convenient anyway since it is compared to a size_t variable.
12365 Variadic C functions now count arguments with size_t, not int.
12366 This avoids an unnecessary limitation on 64-bit machines, which
12367 caused (substring ...) to crash on large vectors (Bug#8344).
12368 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
12369 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
12370 All variadic functions and their callers changed accordingly.
12371 (struct gcpro.nvars): Now size_t, not int. All uses changed.

12375 (internal_condition_case_n, run_hook_with_args, apply_lambda)
12376 (funcall_lambda, mark_backtrace): Likewise.
12377 * fns.c (concat): Likewise.
12378 * frame.c (x_set_frame_parameters): Likewise.
12379 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12380 0 if not found, not -1. All callers changed.
12382 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12383 (stack_copy_size): Now size_t, not int.
12384 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12386 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12388 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
12389 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12390 All callers changed.
12392 * lisp.h (multibyte_char_to_unibyte):
12393 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12394 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12395 * character.h (CHAR_TO_BYTE8):
12396 * cmds.c (internal_self_insert):
12397 * editfns.c (general_insert_function):
12398 * keymap.c (push_key_description):
12399 * search.c (Freplace_match):
12400 * xdisp.c (message_dolog, set_message_1): All callers changed.
12402 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12404 * keyboard.c (safe_run_hook_funcall): New function.
12405 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12406 don't set the hook to nil, but remove the offending function instead.
12407 (Qcommand_hook_internal): Remove, unused.
12408 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12409 Vcommand_hook_internal.
12411 * eval.c (enum run_hooks_condition): Remove.
12412 (funcall_nil, funcall_not): New functions.
12413 (run_hook_with_args): Call each function through a `funcall' argument.
12414 Remove `cond' argument, now redundant.
12415 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
12416 (Frun_hook_with_args_until_failure): Adjust accordingly.
12417 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
12419 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12421 * dispextern.h (string_buffer_position): Remove declaration.
12423 * print.c (strout): Remove parameter `multibyte', unused since
12424 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
12426 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
12427 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
12428 All callers changed.
12430 * w32.c (_wsa_errlist): Use braces for struct initializers.
12432 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
12433 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
12434 All callers changed.
12435 (string_buffer_position): Likewise. Also, make static (it's never
12436 used outside xdisp.c).
12437 (cursor_row_p): Remove parameter `w', unused since
12438 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

12440 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
12441 All callers changed.
12443 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12445 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

12451 (ns_update_auto_hide_menu_bar): New functions.
12452 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

12456 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
12458 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12460 * nsmenu.m (runDialogAt): Remove argument to timer_check.
12462 2011-03-27 Glenn Morris <rgm@gnu.org>
12464 * syssignal.h: Replace RETSIGTYPE with void.
12465 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
12466 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
12467 Replace SIGTYPE with void everywhere.

12471 2011-03-26 Eli Zaretskii <eliz@gnu.org>
12473 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
12474 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
12476 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
12478 * w32.c (read_unc_volume): Use parameter `henum', instead of
12479 global variable `wget_enum_handle'.
12481 * keymap.c (describe_vector): Remove parameters `indices' and
12482 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

12493 * w32menu.c (w32_menu_display_help):
12494 * xmenu.c (show_help_event, menu_help_callback):
12495 Adjust calls to `show_help_echo'.
12497 * gtkutil.c (xg_maybe_add_timer):
12498 * keyboard.c (readable_events):
12499 * process.c (wait_reading_process_output):
12500 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
12502 * insdel.c (adjust_markers_gap_motion):
12503 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

12577 2011-03-23 Julien Danjou <julien@danjou.info>
12579 * term.c (Fsuspend_tty, Fresume_tty):
12580 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
12581 * window.c (temp_output_buffer_show):

12588 * callint.c (Fcall_interactively):
12589 * buffer.c (Fkill_all_local_variables):
12590 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12592 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
12593 unconditionally since it does the check itself.
12595 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12597 Fix more problems found by GCC 4.5.2's static checks.
12599 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12600 the first time through the loop, since we know p0 < p1 then.
12601 This also avoids a gcc -Wstrict-overflow warning.
12603 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12604 leading to a memory leak, possible in functions like
12605 load_charset_map_from_file that can allocate an unbounded number
12606 of objects (Bug#8318).
12608 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12609 that could (at least in theory) be that large.
12611 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12612 This is less likely to overflow, and avoids undefined behavior if
12613 overflow does occur. All callers changed. Use strtoul to scan
12614 for the unsigned long integer.
12615 (pint2hrstr): Simplify and tune code slightly.
12616 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
12618 * scroll.c (do_scrolling): Work around GCC bug 48228.
12619 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

12624 This also avoids a warning with gcc -Wstrict-overflow.
12626 * fileio.c (Fcopy_file): Report error if fchown or fchmod
12629 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12631 * process.c (Fmake_network_process): Use socklen_t, not int,
12632 where POSIX says socklen_t is required in portable programs.
12633 This fixes a porting bug on hosts like 64-bit HP-UX, where
12634 socklen_t is wider than int (Bug#8277).
12635 (Fmake_network_process, server_accept_connection):
12636 (wait_reading_process_output, read_process_output):
12639 * process.c: Rename or move locals to avoid shadowing.
12640 (list_processes_1, Fmake_network_process):
12641 (read_process_output_error_handler, exec_sentinel_error_handler):
12642 Rename or move locals.
12643 (Fmake_network_process): Define label "retry_connect" only if needed.
12644 (Fnetwork_interface_info): Fix pointer signedness.
12645 (process_send_signal): Add cast to avoid pointer signedness problem.
12646 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
12647 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
12649 Make tparam.h and terminfo.c consistent.
12650 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12651 Include tparam.h instead, since it declares them.
12652 * cm.h (PC): Remove extern decl; tparam.h now does this.
12653 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12654 * terminfo.c: Include tparam.h, to check interfaces.
12655 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12656 (tparam): Adjust signature to match interface in tparam.h;
12657 this removes some undefined behavior. Check that outstring and len
12658 are zero, which they always are with Emacs.
12659 * tparam.h (PC, BC, UP): New extern decls.
12661 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12662 (xftfont_open): Rename locals to avoid shadowing.
12664 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
12665 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
12666 (OTF_TAG_SYM): Omit macro if not needed.
12667 (ftfont_list): Remove unused local.
12668 (get_adstyle_property, ftfont_pattern_entity):
12669 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
12670 Rename locals to avoid shadowing.
12672 * xfont.c (xfont_list_family): Mark var as initialized.
12674 * xml.c (make_dom): Now static.
12676 * composite.c (composition_compute_stop_pos): Rename local to
12678 (composition_reseat_it): Remove unused locals.
12679 (find_automatic_composition, composition_adjust_point): Likewise.
12680 (composition_update_it): Mark var as initialized.
12681 (find_automatic_composition): Mark vars as initialized,
12682 with a FIXME (Bug#8290).
12684 character.h: Rename locals to avoid shadowing.
12685 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
12686 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
12687 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
12688 (BUF_DEC_POS): Be more systematic about renaming local temporaries
12689 to avoid shadowing.
12691 * textprop.c (property_change_between_p): Remove; unused.
12693 * intervals.c (interval_start_pos): Now static.
12695 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
12697 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
12698 Rename locals to avoid shadowing.
12700 * sound.c (wav_play, au_play, Fplay_sound_internal):
12701 Fix pointer signedness.
12702 (alsa_choose_format): Remove unused local var.
12703 (wav_play): Initialize a variable to 0, to prevent undefined
12704 behavior (Bug#8278).
12706 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12708 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12710 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12711 clobbering (Bug#8298).
12712 * sysdep.c (sys_subshell): Likewise.
12713 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12715 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.

12889 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12890 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
12891 to use the following functions instead of these macros.
12892 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
12893 EMACS_INT, since callers assume the returned value fits in int.
12894 (upcase1): Likewise, for UPCASE_TABLE.
12895 (uppercasep, lowercasep, upcase): New static inline functions.
12896 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

12906 (regex_compile, re_match_2_internal): Mark locals as initialized.
12907 (RETALLOC_IF): Define only if needed.
12908 (WORDCHAR_P): Likewise. This one is never needed, but is used
12909 only in a comment talking about a compiler bug, so put inside
12910 the #if 0 of that comment.
12911 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
12912 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

12939 New macros, so that the caller can use some names other than
12940 gcpro1, gcpro2, etc.
12941 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
12943 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
12944 argument, for consistency with GCPRO2_VAR, etc: it is now the
12945 prefix of the variable, not the variable itself. All uses
12947 * dired.c (directory_files_internal, file_name_completion):
12948 Rename locals to avoid shadowing.
12950 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
12951 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
12952 dired.c's scmp function, had undefined behavior.
12953 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12954 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
12955 * buffer.h: ... to here, because these macros use current_buffer,
12956 and the new implementation with inline functions needs to have
12957 current_buffer in scope now, rather than later when the macros
12959 (downcase, upcase1): New static inline functions.
12960 (DOWNCASE, UPCASE1): Reimplement using these functions.
12961 This avoids undefined behavior in expressions like
12962 DOWNCASE (x) == DOWNCASE (y), which previously suffered
12963 from race conditions in accessing the global variables
12964 case_temp1 and case_temp2.
12965 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
12966 * lisp.h (case_temp1, case_temp2): Remove their decls.
12967 * character.h (ASCII_CHAR_P): Move from here ...
12968 * lisp.h: ... to here, so that the inline functions mentioned
12969 above can use them.
12971 * dired.c (directory_files_internal_unwind): Now static.
12973 * fileio.c (file_name_as_directory, directory_file_name):

12976 (file_name_as_directory): Use const pointers when appropriate.
12977 (Fexpand_file_name): Likewise. In particular, newdir might
12978 point at constant storage, so make it a const pointer.
12979 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
12980 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
12982 (Fset_file_times, Finsert_file_contents, auto_save_error):

12987 to avoid shadowing.
12989 * marker.c (bytepos_to_charpos): Remove; unused.
12991 * lisp.h (verify_bytepos, count_markers): New decls,
12992 so that gcc does not warn that these functions aren't declared.
12994 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
12995 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
12996 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
12997 (copy_text): Remove unused local var.
12999 * filelock.c (within_one_second): Now static.
13000 (lock_file_1): Rename local to avoid shadowing.
13002 * buffer.c (fix_overlays_before): Mark locals as initialized.
13003 (fix_start_end_in_overlays): Likewise. This function should be
13004 simplified by using pointers-to-pointers, but that's a different
13006 (switch_to_buffer_1): Now static.
13007 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13008 (report_overlay_modification): Rename locals to avoid shadowing.
13010 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13011 Fix pointer signedness issue.
13012 (sys_subshell): Mark local as volatile if checking for lint,
13013 to suppress a gcc -Wclobbered warning that does not seem to be right.
13014 (MAXPATHLEN): Define only if needed.
13016 * process.c (serial_open, serial_configure): Move decls from here ...
13017 * systty.h: ... to here, so that they can be checked.
13019 * fns.c (get_random, seed_random): Move extern decls from here ...
13020 * lisp.h: ... to here, so that they can be checked.
13022 * sysdep.c (reset_io): Now static.
13023 (wait_for_termination_signal): Remove; unused.
13025 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

13028 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13029 (DENSE_TABLE_SIZE): Remove; unused.
13030 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13031 (describe_map_tree):
13032 Rename locals to avoid shadowing.
13034 * keyboard.c: Declare functions static if they are not used elsewhere.
