3 * s/gnu.h, s/gnu-linux.h:
4 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
6 2012-07-11 John Wiegley <johnw@newartisans.com>
8 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9 function attribute, so we only use it if it exists in the
12 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
14 Avoid call to strlen in fast_c_string_match_ignore_case.
15 * search.c (fast_c_string_match_ignore_case): Change to use
16 length argument. Adjust users accordingly.
17 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
19 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>
22 * sysdep.c (rename) [!HAVE_RENAME]: Remove.
25 * s/hpux10-20.h (HAVE_PERROR): Remove.
26 * sysdep.c (perror) [HPUX && !HAVE_PERROR]:
27 Remove dummy definition, as this problem was obsolete long ago.
30 * sysdep.c (strerror) [!HAVE_STRERROR && !WINDOWSNT]: Remove.
32 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
34 Avoid calls to strlen in font processing functions.

56 Remove "#define unix" that is no longer needed (Bug#11905).
57 * s/aix4-2.h (unix): Remove; no longer needed.
59 EMACS_TIME simplification (Bug#11875).
60 This replaces macros (which typically do not work in GDB)
61 with functions, typedefs and enums, making the code easier to debug.
62 The functional style also makes code easier to read and maintain.
63 * systime.h: Include <sys/time.h> on all hosts, not just if
64 WINDOWSNT, since 'struct timeval' is needed in general.
65 (EMACS_TIME): Now a typedef, not a macro.
66 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
68 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
69 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
70 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
71 (EMACS_TIME_LE): Now functions, not macros.
72 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
73 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
74 which are not functions. All uses rewritten to use:

76 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
77 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
78 not functions. All uses rewritten to use the following, respectively:
79 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
80 (add_emacs_time, sub_emacs_time): New functions.
81 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
82 * fileio.c (Fcopy_file):
83 * xterm.c (XTflash): Get the current time closer to when it's used.
84 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
86 * bytecode.c (targets): Suppress -Woverride-init warnings.
88 Simplify by avoiding confusing use of strncpy etc.
89 * doc.c (Fsnarf_documentation):
90 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
91 * frame.c (Fmake_terminal_frame):
92 * gtkutil.c (get_utf8_string):
94 * nsmenu.m (ns_update_menubar):
96 Prefer memcpy to strncpy and strncat when either will do.
97 * fileio.c (Fsubstitute_in_file_name):
98 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
99 (menu_separator_name_p):
100 * nsmenu.m (ns_update_menubar):
101 Prefer memcmp to strncmp when either will do.
102 * nsterm.m: Include <ftoastr.h>.
104 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
105 Prefer snprintf to strncpy.
106 * nsterm.m (ns_term_init):
107 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
108 * nsterm.m (ns_term_init):
109 Avoid the need for strncpy, by using build_string or
110 make_unibyte_string directly. Use dtoastr, not snprintf.
111 * process.c (Fmake_network_process): Diagnose service names that
112 are too long, rather than silently truncating them or creating
113 non-null-terminated names.
114 (Fnetwork_interface_info): Likewise, for interface names.
115 * sysdep.c (system_process_attributes) [GNU_LINUX]:
116 Prefer sprintf to strncat.
117 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
118 Prefer vsnprintf to vsprintf + strncpy.
120 2012-07-10 Glenn Morris <rgm@gnu.org>
122 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
123 Clarify fallback case.
125 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
127 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
128 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
129 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
130 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
131 where argument type is known to be a Lisp_Cons.
133 2012-07-10 Tom Tromey <tromey@redhat.com>
135 * bytecode.c (BYTE_CODE_THREADED): New macro.
136 (BYTE_CODES): New macro. Replaces all old byte-code defines.
137 (enum byte_code_op): New type.
138 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
139 (exec_byte_code): Use them. Use token threading when applicable.
141 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
143 Optimize pure C strings initialization.
144 * lisp.h (make_pure_string): Fix prototype.
145 (build_pure_c_string): New function, defined as static inline. This
146 provides a better opportunity to optimize away calls to strlen when
147 the function is called with compile-time constant argument.
148 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
149 argument, adjust users accordingly. Use build_pure_c_string where
151 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
152 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
153 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
155 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
157 Avoid calls to strlen in miscellaneous functions.

159 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
160 * lread.c (openp): Likewise.
162 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
164 Avoid calls to strlen in path processing functions.
165 * fileio.c (file_name_as_directory): Add comment. Change to add
166 srclen argument and return the length of result. Adjust users
168 (directory_file_name): Fix comment. Change to add srclen argument,
169 swap 1st and 2nd arguments to obey the common convention. Adjust
171 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
173 2012-07-10 Glenn Morris <rgm@gnu.org>
175 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
176 Move PENDING_OUTPUT_COUNT definition to configure.
178 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
179 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
180 * s/gnu.h (DATA_START): Move definitions to configure.
182 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
183 We include usg5-4-common.h, which defines them both.
185 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
186 O_RDONLY already includes it).
188 Stop ns builds setting the EMACSLOADPATH environment variable.
189 * nsterm.m (ns_load_path): Rename from ns_init_paths.
190 Now it does not set EMACSLOADPATH, just returns the load-path string.
191 * nsterm.h: Update accordingly.
192 * lread.c [HAVE_NS]: Include nsterm.h.
193 (init_lread) [HAVE_NS]: Use ns_load_path.
194 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
196 2012-07-09 Glenn Morris <rgm@gnu.org>
198 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
199 since the included bsd-common.h does so.
201 Stop ns builds setting the EMACSPATH environment variable.
202 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
203 (ns_init_paths): Do not set EMACSPATH.
204 * nsterm.h (ns_exec_path): Add it.
205 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
208 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
210 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
212 * process.c (wait_reading_process_output): 'waitchannels' was unset
213 when read_kbd || !NILP (wait_for_cell); fix this.
215 Add GCC-style 'const' attribute to functions that can use it.
216 * character.h (char_resolve_modifier_mask):
217 * keyboard.h (make_ctrl_char):
218 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
219 (init_character_once, next_almost_prime, init_fns, init_image)
220 (flush_pending_output, init_sound):
221 * mem-limits.h (start_of_data):
222 * menu.h (finish_menu_items):
224 * emacs.c (DEFINE_DUMMY_FUNCTION):
225 Declare the dummy function with ATTRIBUTE_CONST.
226 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
227 Add decls with ATTRIBUTE_CONST.
229 Minor improvements to make_formatted_string.
230 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
231 where int is good enough, as vsprintf returns an int.
232 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
234 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
236 Use make_formatted_string to avoid double length calculation.
237 * lisp.h (make_formatted_string): New prototype.
238 * alloc.c (make_formatted_string): New function.
239 * buffer.c (Fgenerate_new_buffer_name): Use it.
240 * dbus.c (syms_of_dbusbind): Likewise.

261 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
263 Move marker debugging code under MARKER_DEBUG.
264 * marker.c (MARKER_DEBUG): Move marker debugging code under
265 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
266 for bootstrap with --enable-checking (~3x slowdown reported
267 by Juanma Barranquero <lekktu@gmail.com>).
268 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
270 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
272 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
273 See <http://bugs.gnu.org/11825#29>.

277 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
278 has no font, use the frame's font. (Bug#11813)
279 (display_line): Add commentary about displaying truncation glyphs
281 (produce_special_glyphs): Move here from term.c.
283 * term.c (produce_special_glyphs): Move to xdisp.c.
285 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
288 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
290 * xdisp.c (display_line): Avoid warning about implicit declaration
293 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
295 * lisp.h: Remove empty conditional.
297 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
299 * lread.c (load_path_check): Now static.
301 Fix some minor --with-ns problems found by static checking.
302 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
303 (x_set_font) [!HAVE_X_WINDOWS]:
304 * image.c (xpm_load_image) [HAVE_NS]:
305 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
306 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
308 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
309 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
310 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
311 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
312 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
313 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
314 Fix pointer signedness problem.
315 * xfaces.c (FRAME_X_FONT_TABLE):
316 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
318 2012-07-07 Glenn Morris <rgm@gnu.org>
320 * lread.c (load_path_check): New function, split from init_lread.
321 (init_lread): Reorganize. Motivation:
322 If EMACSLOADPATH is set, check/warn about that rather than the
323 defaults, which we are not going to use. Hence we can remove
324 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
325 Don't warn if site-lisp directories are missing.
326 If not installed, start from a blank load-path, since
327 PATH_LOADSEARCH refers to the eventual installation directories.
329 2012-07-07 Eli Zaretskii <eliz@gnu.org>
331 Support truncation and continuation glyphs on GUI frames, when
332 fringes are disabled. (Bug#11832)
333 * xdisp.c (init_iterator): Get dimensions of truncation and
334 continuation glyphs even if on GUI frames. Adjust
335 it->last_visible_x on GUI frames when the left or right fringes,
337 (start_display, move_it_in_display_line_to): Handle the case of a
338 GUI frame without a fringe to display continuation or truncation
340 (insert_left_trunc_glyphs): Support GUI frames: make sure
341 truncation glyphs overwrite enough glyphs from the current line to
342 have sufficient space in pixels.
343 (display_line): Support truncation and continuation glyphs on GUI
344 frames. If some spare pixels are left on the line after inserting
345 the truncation glyphs, fill that space with a stretch glyph of a
346 suitably computed width.
348 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
349 produce_glyphs, to support GUI sessions.
351 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
353 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
355 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
357 Do not require float-time's arg to fit in time_t (Bug#11825).
358 This works better on hosts where time_t is unsigned, and where
359 float-time is applied to the (negative) difference between two times.
360 * editfns.c (decode_time_components): Last arg is now double *,
361 not int *, and means to store all the result as a double, without
362 worrying about whether the seconds part fits in time_t.
364 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
366 (Ffloat_time): Do not fail merely because the specified time falls
367 outside of time_t range.
369 2012-07-07 Glenn Morris <rgm@gnu.org>

380 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
382 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
384 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
385 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
386 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
387 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
388 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
389 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
391 * xfont.c (compare_font_names): Redo to omit the need for casts.

396 * w32fns.c (Fx_change_window_property): Doc fix.
398 * w32fns.c (Fx_window_property): Accept the same arguments as the
399 X Windows version. Doc fix.
400 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
402 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
403 Eli Zaretskii <eliz@gnu.org>
405 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
406 Windows-specific code from nt/config.nt moved here.
407 Obsolete settings removed.
409 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
411 * process.c: Avoid unnecessary calls to gettime.
412 (wait_reading_process_output): Don't get the time of day
413 when gobbling data immediately and not waiting, as there's no need
414 for it in that case. This removes a FIXME.
416 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
418 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
419 is defined (Bug#11768).
421 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

424 * marker.c (byte_char_debug_check): Do not perform the check
425 if buffer is not multibyte.
426 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
427 Call byte_char_debug_check with correct arguments.
429 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
431 Compile marker debugging code only if ENABLE_CHECKING is defined.
432 * marker.c (byte_char_debug_check, count_markers):
433 Use only if ENABLE_CHECKING is defined.
434 (byte_debug_flag): Remove.
435 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
436 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
438 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
440 Avoid code repetition in marker-related functions.
441 * marker.c (attach_marker): New function.
442 (Fset_marker, set_marker_restricted, set_marker_both)
443 (set_marker_restricted_both): Use it.
444 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
445 Consistently rename charno to charpos.
446 (marker_position): Add eassert.
447 (marker_byte_position): Convert to eassert.
449 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

466 * window.c (save_window_save): Likewise.
468 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
470 Do not use Fdelete_overlay in delete_all_overlays
471 to avoid redundant calls to unchain_overlay.
472 * buffer.c (drop_overlay): New function.
473 (delete_all_overlays, Fdelete_overlay): Use it.
474 * minibuf.c (get_minibuffer): Fix comment.
476 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
478 Port to OpenBSD 5.1 amd64.
479 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
480 This is needed for OpenBSD, and should be harmless on all BSD systems.
481 Also, include <sys/sysctl.h>, as it should be available on all
482 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
483 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
484 use p_pid member, not kp_proc.pid.
486 2012-07-06 Glenn Morris <rgm@gnu.org>
488 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
490 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
492 More xmalloc and related cleanup.
493 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

501 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
503 Omit needless casts involving void * pointers and allocation.
504 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
505 as the former is more robust if P's type is changed.
506 Prefer xzalloc to xmalloc + memset 0.
507 Simplify malloc-or-realloc to realloc.
508 Don't worry about xmalloc returning a null pointer.
509 Prefer xstrdup to xmalloc + strcpy.
510 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
512 * keyboard.c (apply_modifiers_uncached): Prefer local array to
513 alloca of a constant.
515 2012-07-05 Eli Zaretskii <eliz@gnu.org>
517 * xdisp.c (display_line): Fix horizontal pixel coordinates when
518 hscroll is larger than the line width. Fixes long and futile
519 looping inside extend_face_to_end_of_line (on a TTY) producing
520 glyphs that are not needed and thrown away.
522 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

531 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
533 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
534 not defined (Bug#11768).

538 followed by gtk_box_set_homogeneous (Bug#11768).
539 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
540 (update_theme_scrollbar_width, xg_create_scroll_bar):
541 Use gtk_scrollbar_new (Bug#11768).
542 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
543 (is_box_type): New function (Bug#11768).
544 (xg_tool_item_stale_p): Call is_box_type.
545 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
546 with default display (Bug#11768).

552 coordinates when window's hscroll is set to insanely large
555 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
557 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

619 Problem reported by Troels Nielsen in
620 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
622 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
624 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
625 This should be fixed in a better way; see Eli Zaretskii in
626 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
627 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
629 * fileio.c (time_error_value): Rename from special_mtime.
630 The old name's problems were noted by Eli Zaretskii in
631 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
633 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
634 This variable's comment says Emacs needs at least one GDB-visible
635 symbol of type enum pvec_type, to work around GDB problems.
636 The symbol's value doesn't matter.
638 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
639 that causes compilation to fail on pre-C99 compilers.
641 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
643 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
644 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
646 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
648 * buffer.c (init_buffer_once): Fix initialization of
649 headers for buffer_defaults and buffer_local_symbols.
650 Reported by Juanma Barranquero <lekktu@gmail.com>.
652 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
654 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
655 * lisp.h (enum pvec_type): Use fewer bits.
656 (PSEUDOVECTOR_SIZE_BITS): New constant.
657 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
658 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to

666 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
667 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
668 (sweep_vectors): Use it. Use local var `total_bytes' instead of
669 abusing vector->header.next.nbytes.
670 (live_vector_p): Use PVEC_TYPE.
671 (mark_object): Adapt code to extract pvectype. Use switch.
673 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
675 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
676 Tighten new eassert a bit.
678 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
680 Fix compilation with --enable-gcc-warnings and -O1
682 * doprnt.c (doprnt): Change type of tem to int, initialize
683 to avoid compiler warning. Add eassert.
684 * search.c (simple_search): Initialize match_byte to avoid
685 compiler warning. Add eassert.
687 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
689 Avoid weird behavior with large horizontal scrolls.
690 Without this change, for example, large hscroll values would
691 mess up Emacs's display on Fedora 15 x86, presumably due to
692 overflows in int calculations in the display code.
693 Also, if buffers had long lines, Emacs would freeze.
694 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
695 (set_window_hscroll): New function, containing the old guts of
696 Fset_window_hscroll. Return the clipped value.
697 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
698 This avoids the need to check against PTRDIFF_MAX.
700 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
702 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
704 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
706 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
708 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
709 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
710 since GCC 4.4.6 issues a bogus warning for them.
712 Fix bugs in file timestamp newness comparisons.
713 * fileio.c (Ffile_newer_than_file_p):
714 * lread.c (Fload): Use full timestamp resolution of files,
715 not just the 1-second resolution, so that files that are only
716 slightly newer still count as newer.
717 * fileio.c (Ffile_newer_than_file_p): Don't assume file
718 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
720 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
722 * fileio.c: Improve handling of file time marker. (Bug#11852)
723 (special_mtime): New function.
724 (Finsert_file_contents, Fverify_visited_file_modtime):
725 Use it to set special mtime values consistently.
727 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
729 * fileio.c (Finsert_file_contents): Properly handle st_mtime
730 marker for non-existing file. (Bug#11852)
732 2012-07-03 Glenn Morris <rgm@gnu.org>
734 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
735 and did not make it into globals.h).
737 2012-07-03 Tom Tromey <tromey@redhat.com>

779 buffer for invisible buffers. (Bug#1229)
781 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
783 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
784 values which aren't power of 2.
785 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
786 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
789 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
791 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
793 * alloc.c (mark_object): Revert part of last patch to use `switch'.
795 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
797 * alloc.c (allocate_vector_block): Remove redundant
798 calls to mallopt if DOUG_LEA_MALLOC is defined.
799 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
800 avoid calls to mallopt if zero_vector is returned.
802 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
804 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
805 is enabled, avoid dereferencing NULL current_sblock if
808 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
810 Cleanup basic buffer management.
811 * buffer.h (struct buffer): Change layout to use generic vector
812 marking code. Fix some comments. Change type of 'clip_changed'
813 to bitfield. Remove unused #ifndef old.
814 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
815 (GET_OVERLAYS_AT): Fix indentation.
816 (for_each_per_buffer_object_at): New macro.

819 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
820 * alloc.c (allocate_buffer): Adjust to match new layout of
821 struct buffer. Fix comment.
822 (mark_overlay): New function.
823 (mark_buffer): Use it. Use mark_vectorlike to mark normal
824 Lisp area of struct buffer.
825 (mark_object): Use it. Adjust marking of misc objects
826 and related comments.
828 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
830 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
831 wrapper that is not needed because the wrapped code is a no-op (zero
832 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
833 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
835 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
837 * alloc.c (mark_buffer): Simplify. Remove prototype.
838 (mark_object): Add comment. Reorganize marking of vector-like
839 objects. Use CHECK_LIVE for all vector-like objects except buffers
840 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
841 redundant calls to mark_vectorlike for bool vectors.
843 2012-06-30 Glenn Morris <rgm@gnu.org>
845 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
847 * epaths.in (PATH_SITELOADSEARCH): New.
848 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
849 This is rather than relying on --enable-locallisppath elements
850 having "site-lisp" in their names. (Bug#10208#25, 11658)
852 2012-06-30 Eli Zaretskii <eliz@gnu.org>
854 * w32proc.c (sys_select): Accept and ignore one more argument.
856 * w32.c (emacs_gnutls_pull): Call select with one more argument.
858 * sysselect.h [DOS_NT]: Don't include sys/select.h.
859 (pselect) [!MS_DOS]: Redirect to sys_select.
861 * sysdep.c: Don't include dos.h and dosfns.h.
863 * process.c (sys_select):
864 * msdos.c (sys_select): Accept one more argument and ignore it.
866 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
867 adapt data types and code to that.
870 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
871 which clashes with the gnulib function of the same name.
873 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
875 * font.c (font_style_to_value, font_style_symbolic)
876 (font_prop_validate_style): Add type checks for values in
879 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
881 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
884 2012-06-29 Eli Zaretskii <eliz@gnu.org>
886 * xdisp.c (try_window_id): Undo last change.
888 * w32.c (getwd): Adjust commentary about startup_dir.
889 (init_environment): Always call sys_access, even in non-MSVC
890 builds. Don't chdir to the directory of the Emacs executable.
891 This undoes code from 1997 which was justified by the need to
892 "avoid conflicts when removing and renaming directories". But its
893 downside was that every relative file name was being interpreted
894 relative to the directory of the Emacs executable, which can never
895 be TRT. In particular, it broke sys_access when called with
897 (sys_access): Map GetLastError to errno.
899 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
901 * window.h (struct window): Change type of 'fringes_outside_margins'
902 to bitfield. Fix comment. Adjust users accordingly.
903 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
905 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
908 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
910 * gnutls.c (emacs_gnutls_handshake):
911 Add QUIT to make the loop interruptible.
913 2012-06-29 Glenn Morris <rgm@gnu.org>
915 * charset.c (init_charset): Make lack of etc/charsets fatal.
917 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
919 * editfns.c (region_limit): Fix type mismatch.
921 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
923 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
924 undefined. Convert from xassert to eassert.
925 * nsmenu.m: Convert from xassert to eassert.
926 * nsterm.m: Likewise.
928 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

934 Avoid integer overflow on scroll-left and scroll-right.
935 * window.c (HSCROLL_MAX): New macro.
936 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
937 overflow when requested scroll falls outside ptrdiff_t range.
939 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
941 * window.h (struct window): Change type of 'hscroll',
942 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
943 'last_modified' and 'last_overlay_modified' to EMACS_INT.
944 Adjust users accordingly.
945 * xdisp.c (try_cursor_movement): Replace type check with eassert.
946 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
947 from EMACS_INT to ptrdiff_t.
948 (make_window): Omit redundant initialization.
950 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
952 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
954 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
956 * window.h (struct window): Change type of 'use_time' and
957 'sequence_number' from Lisp_Object to int.
958 * frame.c (make_frame): Adjust users accordingly.
959 * print.c (print_object): Likewise.
960 * window.c (select_window, Fwindow_use_time, make_parent_window)
961 (make_window): Likewise.
963 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
965 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
966 enabled with --enable-checking=[all,glyphs] configure option.
967 Fix GLYPH_DEBUG usage assuming that it may be undefined,
968 adjust comments accordingly.
969 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
970 undefined, adjust comments accordingly.

1091 Use sprintf return value instead of invoking strlen on result.
1092 In the old days this wasn't portable, since some sprintf
1093 implementations returned char *. But they died out years ago and
1094 Emacs already assumes sprintf returns int.
1095 Similarly for float_to_string.
1096 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

1104 Use sprintf or float_to_string result to avoid need to call strlen.
1105 * data.c (Fnumber_to_string):
1106 Use make_unibyte_string, since the string must be ASCII.
1107 * lisp.h, print.c (float_to_string): Now returns int length.
1108 * term.c (produce_glyphless_glyph):
1109 Use sprintf result rather than recomputing it.
1111 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1112 * Makefile.in (ALL_CFLAGS):
1113 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

1144 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

1149 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1150 instead of truncating it to 63 (admittedly a generous limit).

1210 * keyboard.c (kbd_buffer_get_event):
1211 * process.c (Faccept_process_output):
1212 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1213 This improves on the previous patch, which introduced a bug
1214 when time_t is unsigned and as wide as intmax_t.
1215 See <http://bugs.gnu.org/9000#51>.
1217 2012-06-23 Eli Zaretskii <eliz@gnu.org>

1234 Privately reported by Herbert J. Skuhra.
1235 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

1246 language ID in the event parameters.
1248 * w32term.c (w32_read_socket): Put the new keyboard codepage into

1280 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1282 Support higher-resolution time stamps (Bug#9000).
1283 The time stamps are only nanosecond-resolution at the C level,
1284 since that's the best that any real-world system supports now.
1285 But they are picosecond-resolution at the Lisp level, as that's
1286 easy, and leaves room for future OS improvements.
1288 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1291 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1292 Don't get current time unless it's needed.
1294 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1295 now provides it if it's absent.
1296 (start_atimer): Port to higher-res time stamps.
1297 Check for time stamp overflow. Don't get current time more
1298 often than is needed.
1300 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1301 Include systime.h, not time.h.
1302 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1304 * dired.c: Include stat-time.h.
1305 (Ffile-attributes): File times now have higher resolution.

1308 (struct image): Timestamp now has higher resolution.
1310 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1311 has at least microseconds now. All uses removed.
1312 (update_frame, update_single_window, update_window, update_frame_1)
1313 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1315 * editfns.c (time_overflow): Now extern.
1316 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1317 (float-time, Fformat_time_string, Fcurrent_time_string)

1321 (decode_time_components, lisp_seconds_argument): New functions.
1322 (make_time): Now static.
1323 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1324 Report an error if the time is invalid, rather than having the caller
1327 * fileio.c: Include <stat-time.h>
1328 (Fcopy_file): Copy higher-resolution time stamps.
1329 Prefer to set the time stamp via a file descriptor if that works.

1331 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1332 (Fvisited_file_modtime, Fset_visited_file_modtime):
1333 Support higher-resolution time stamps.
1335 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1337 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1339 * image.c (prepare_image_for_display, clear_image_cache)
1340 (lookup_image): Port to higer-resolution time stamps.
1342 * keyboard.c (start_polling, bind_polling_period):
1343 Check for time stamp overflow.
1344 (read_char, kbd_buffer_get_event, timer_start_idle)
1345 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1346 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1347 Port to higher-resolution time stamps. Do not assume time_t is signed.
1348 (decode_timer): New function. Timers are now vectors of length 9,
1349 not 8, to accommodate the picosecond component.
1350 (timer_check_2): Use it.
1352 * nsterm.m (select_timeout, timeval_subtract): Remove.
1353 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1354 as they're a bit more accurate and handle overflow better.
1355 (ns_select): Change prototype to be compatible with pselect.
1356 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1357 * nsterm.h (ns_select): Adjust prototype.
1359 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1360 us-resolution time stamps.
1361 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1363 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1365 * lisp.h (time_overflow): New decl.
1366 (wait_reading_process_output): First arg is now intmax_t, not int,
1367 to accommodate larger waits.
1369 * process.h (struct Lisp_Process.read_output_delay):
1370 Now counts nanoseconds, not microseconds.
1371 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1373 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1374 (wait_reading_process_output):
1375 Port to ns-resolution time stamps.
1376 (Faccept_process_output, wait_reading_process_output):
1377 Check for time stamp overflow. Do not assume time_t is signed.
1378 (select_wrapper): Remove; we now use pselect.
1379 (Fprocess_attributes): Now generates ns-resolution time stamps.
1381 * sysdep.c: Include utimens.h. Don't include utime.h
1382 or worry about struct utimbuf; gnulib does that for us now.
1383 (gettimeofday): Remove; gnulib provides a substitute.
1384 (make_timeval): New function.
1385 (set_file_times): Now sets ns-resolution time stamps.
1386 New arg FD; all uses changed.
1387 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1388 (system_process_attributes):
1389 Now returns ns-resolution time stamp. All uses changed.
1390 Check for time stamp overflow.
1392 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1393 provides a substitute now.
1395 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1396 since it guarantees struct timespec.
1397 (EMACS_TIME): Now struct timespec, so that we can support
1398 ns-resolution time stamps.
1399 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1400 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1401 (EMACS_USECS): Remove.
1402 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1403 so multiply the arg by 1000 before storing it.
1404 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1406 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1407 Port to ns-resolution time stamps.
1408 (EMACS_TIME_NEG_P): Remove; replaced by....
1409 (EMACS_TIME_SIGN): New macro.
1410 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
1411 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

1413 (make_timeval, make_lisp_time, decode_time_components): New decls.
1414 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1415 that it mishandled time_t overflow. You can't compare by subtracting!
1416 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1417 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1419 * term.c: Include <sys/time.h>.
1420 (timeval_to_Time): New function, for proper overflow wraparound.
1421 (term_mouse_position, term_mouse_click): Use it.
1423 * undo.c (record_first_change): Support higher-resolution time stamps
1425 (Fprimitive_undo): Use them when restoring time stamps.
1427 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1428 (w32_get_internal_run_time):
1429 Port to higher-resolution Emacs time stamps.
1430 (ltime): Now accepts single 64-bit integer, as that's more convenient
1433 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1435 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1436 for compatibility with pselect. Support ns-resolution time stamps.
1438 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1440 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1441 Check for time stamp overflow, and support ns-resolution time stamps.
1443 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1444 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1445 (timeval_subtract): Remove; no longer needed.
1446 (XTflash, XTring_bell, x_wait_for_event):
1447 Port to ns-resolution time stamps. Don't assume time_t is signed.
1449 2012-06-22 Chong Yidong <cyd@gnu.org>
1451 * xdisp.c (x_consider_frame_title): Revert last change.
1453 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1455 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1456 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1457 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1458 staticidx goes up to 1597 out of 1600 = 0x640.)
1460 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1462 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1463 Otherwise, the umask might be mistakenly 0 while handling input signals.
1465 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
1467 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
1469 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
1471 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
1472 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:

1732 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
1733 Use an inline function on all platforms when using the union type,
1734 since this is simpler and 'static inline' can be used portably

1879 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
1880 would mishandle a string argument "Xc" if X was a multibyte

1954 change it's type from Lisp_Object to bitfield.
1955 Change type of 'force_start', 'optional_new_start',
1956 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
1957 fields from Lisp_Object to bitfield. Adjust users accordingly.
1959 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
1961 Pacify gcc -Wdouble-precision when using Xaw.
1962 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
1963 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
1964 Use 'float' consistently, rather than 'float' in most places
1965 and 'double' in a couple of places.
1967 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1969 * xdisp.c (handle_stop): Detect whether we have overlay strings
1970 loaded by testing it->current.overlay_string_index to be
1971 non-negative, instead of checking whether n_overlay_strings is
1972 positive. (Bug#11587)
1974 2012-05-31 Chong Yidong <cyd@gnu.org>
1976 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
1978 * doc.c (Fsubstitute_command_keys): Doc fix.
1980 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1982 * search.c (search_buffer): Remove calls to
1983 r_alloc_inhibit_buffer_relocation, as it is now called by
1984 maybe_unify_char, which was the cause of relocation of buffer text
1987 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1989 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
1990 for the duration of call to load_charset, to avoid problems with
1991 callers of maybe_unify_char that access buffer text through C
1994 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
1995 decrement the inhibition flag, instead of just setting or
1998 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2000 Remove obsolete '#define static' cruft.
2001 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2002 This #undef was "temporary" in 2000; it is no longer needed
2003 now that '#define static' has gone away.
2004 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2005 (gray_bitmap_bits): Remove; no longer needed.
2006 All uses replaced with definiens.
2007 * xterm.c: Include "bitmaps/gray.xbm".
2009 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2011 Clean up __executable_start, monstartup when --enable-profiling.
2012 The following changes affect the code only when profiling.
2013 * dispnew.c (__executable_start): Rename from safe_bcopy.
2014 Define only on platforms that need it.
2015 * emacs.c: Include <sys/gmon.h> when profiling.
2016 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2017 (__executable_start): Remove decl, since lisp.h does it now.
2018 (safe_bcopy): Remove decl; no longer has that name.
2019 (main): Coalesce #if into single bit of code, for simplicity.
2020 Cast pointers to uintptr_t, since standard libraries want integers
2022 * lisp.h (__executable_start): New decl.
2024 2012-05-31 Glenn Morris <rgm@gnu.org>
2026 * image.c (Fimagemagick_types): Doc fix.
2028 2012-05-30 Jim Meyering <meyering@redhat.com>
2030 * callproc.c (Fcall_process_region): Include directory component
2031 in mkstemp error message (Bug#11586).

2044 * lisp.h (Qdefun): Remove.
2045 * lread.c (read1): Tiny simplification.
2047 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2049 Do not create empty overlays with the evaporate property (Bug#9642).
2050 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2051 Bug#9642, but explicitly check that the buffer the overlay would
2052 be moved to is live and rearrange lines to make sure that errors
2053 will not put the overlay in an inconsistent state.
2054 (Fdelete_overlay): Cosmetics.
2056 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2058 * w32term.c (my_bring_window_to_top): New function.
2059 (x_raise_frame): Use handle returned by DeferWindowPos, which
2060 could be different from the original one.

2064 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2065 by calling BringWindowToTop.
2067 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
2068 (WM_EMACS_END): Increase by one.
2070 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2072 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2073 This avoids undefined behavior that might cause the eassert
2074 to not catch an out-of-range value.
2076 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2078 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2079 Update dependencies.
2081 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2083 * bidi.c (bidi_mirror_char): Fix last change.
2085 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
2087 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
2088 when referring to sectname field in printf format.
2090 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2092 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2093 Only r_alloc_inhibit_buffer_relocation needed to be added;
2094 the others were already declared.
2096 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2097 before checking whether it's out of range. Put the check inside
2099 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2101 2012-05-27 Ken Brown <kbrown@cornell.edu>
2103 * callproc.c (Fcall_process): Restore a line that was accidentally
2104 commented out in the 2011-02-13 change (bug#11547).
2106 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2108 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2109 defined on ralloc.c.
2111 * buffer.c [REL_ALLOC]: Remove prototypes of
2112 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2113 they are now on lisp.h.
2115 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2117 * search.c (search_buffer): Use it to inhibit relocation of buffer
2118 text while re_search_2 is doing its job, because re_search_2 is
2119 passed C pointers to buffer text. (Bug#11519)
2121 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2124 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2125 state after an additional call to move_it_in_display_line_to, keep
2126 the values of it->max_ascent and it->max_descent found for the
2128 (pos_visible_p): Revert the comparison against bottom_y to what it
2129 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2132 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2134 Fix coding-related core dumps with gcc -ftrapv.
2135 The code was computing A - B, where A and B are pointers, and B is
2136 random garbage. This can lead to core dumps on platforms that
2137 have special pointer registers, and it also leads to core dumps on
2138 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2139 A - B only when B is initialized properly.
2140 * coding.c (coding_set_source, coding_set_destination): Return void.
2141 (coding_change_source, coding_change_destinations): New functions,
2142 with the old behaviors of coding_set_source and coding_set_destination.
2143 All callers that need an offset changed to use these new functions.
2145 2012-05-26 Glenn Morris <rgm@gnu.org>
2147 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2149 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2151 Extend mouse support on W32 text-mode console.
2152 * xdisp.c (draw_row_with_mouse_face):
2153 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2155 * w32console.c: Include window.h.
2156 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2158 (initialize_w32_display): Initialize mouse-highlight data.
2160 * w32inevt.c: Include termchar.h and window.h.
2161 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2162 moves, call note_mouse_highlight. If help_echo changed, call
2163 gen_help_event to produce help-echo message in the echo area.
2164 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2167 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2169 * lread.c (read1): Simplify slightly to avoid an overflow warning
2170 with GCC 4.7.0 on x86-64.
2172 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2174 * bidi.c (bidi_mirror_char): Revert last change: an int is
2175 definitely wide enough here.
2177 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2179 Fix integer width and related bugs (Bug#9874).
2180 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
2181 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
2182 (string_bytes, check_sblock, allocate_string_data):

2185 (make_string_from_bytes, make_specified_string)
2186 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
2187 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2189 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2190 (allocate_pseudovector):
2191 Use int, not EMACS_INT, where int is wide enough.
2192 (inhibit_garbage_collection, Fgarbage_collect):
2193 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2194 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2195 int might not be wide enough.
2196 (bidi_cache_search, bidi_cache_find, bidi_init_it)
2197 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2198 (bidi_at_paragraph_end, bidi_find_paragraph_start)
2199 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2200 (bidi_level_of_next_char, bidi_move_to_visually_next):
2201 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2202 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2203 (Fkill_buffer, Fset_buffer_major_mode)
2204 (advance_to_char_boundary, Fbuffer_swap_text)
2205 (Fset_buffer_multibyte, overlays_at, overlays_in)
2206 (overlay_touches_p, struct sortvec, record_overlay_string)
2207 (overlay_strings, recenter_overlay_lists)
2208 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2209 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
2210 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2211 (Foverlay_recenter, last_overlay_modification_hooks_used)
2212 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2213 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2214 (validate_region): Omit unnecessary test for b <= e,
2215 since that's guaranteed by the previous test.
2216 (adjust_overlays_for_delete): Avoid pos + length overflow.
2217 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2218 (report_overlay_modification):
2219 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2220 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2221 Omit pointer cast, which isn't needed anyway, and doesn't work
2222 after the EMACS_INT -> ptrdiff_t change.
2223 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2224 * buffer.h: Adjust decls to match defn changes elsewhere.
2225 (struct buffer_text, struct buffer):

2227 Use EMACS_INT, not int, where int might not be wide enough.
2228 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
2229 not int, to avoid needless 32-bit limit on 64-bit hosts.
2230 (exec_byte_code): Use tighter memory-full test, one that checks
2231 for alloca overflow. Don't compute the address of the object just
2232 before an array, as that's not portable. Use EMACS_INT, not
2233 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2234 * callint.c (Fcall_interactively):
2235 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2236 * callproc.c (call_process_kill, Fcall_process):
2237 Don't assume pid_t fits into an Emacs fixnum.
2238 (call_process_cleanup, Fcall_process, child_setup):

2240 (call_process_cleanup, Fcall_process, delete_temp_file)
2241 (Fcall_process_region):
2242 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2243 (Fcall_process): Simplify handling of volatile integers.
2244 Use int, not EMACS_INT, where int will do.
2245 * casefiddle.c (casify_object, casify_region, operate_on_word)
2246 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2247 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2248 (casify_object): Avoid integer overflow when overallocating buffer.
2249 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2250 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2251 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2252 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2253 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2254 integers are now checked earlier. All uses replaced with XINT.
2256 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2257 For CCL_MapSingle, check that content and value are in int range.
2258 (ccl_driver, Fregister_code_conversion_map):
2259 Check that Vcode_version_map_vector is a vector.
2260 (resolve_symbol_ccl_program): Check that vector header is in range.
2261 Always copy the vector, so that we can check its contents reliably
2262 now rather than having to recheck each instruction as it's being
2263 executed. Check that vector words fit in 'int'.
2264 (ccl_get_compiled_code, Fregister_ccl_program)
2265 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2266 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2267 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2268 contents are in range.
2269 (Fccl_execute_on_string): Check that status is in range.
2270 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2271 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2272 Accept and return EMACS_INT, not int, because callers can pass values
2274 (c_string_width, strwidth, lisp_string_width, chars_in_text)

2276 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
2277 (str_as_unibyte, str_to_unibyte, string_count_byte8)
2278 (string_escape_byte8, Fget_byte):
2279 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2280 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2281 avoid mishandling large integers.
2282 * character.h: Adjust decls to match defn changes elsewhere.
2283 * charset.c (load_charset_map_from_file, find_charsets_in_text)
2284 (Ffind_charset_region):
2285 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2286 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
2287 (load_charset_map_from_vector, Fdefine_charset_internal):
2288 Don't assume fixnum fits in int.
2289 (load_charset_map_from_vector, Fmap_charset_chars):
2290 Remove now-unnecessary CHECK_NATNUMs.
2291 (Fdefine_charset_internal): Check ranges here, more carefully.
2292 Don't rely on undefined behavior with signed left shift overflow.
2293 Don't assume unsigned int fits into fixnum, or that fixnum fits
2294 into unsigned int. Don't require max_code to be a valid fixnum;
2295 that's not true for gb10830 4-byte on a 32-bit host. Allow
2296 invalid_code to be a cons, for the same reason. Require code_offset
2297 to be a character. Avoid int overflow if max_char is close
2299 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2300 this is intended anyway and avoids some undefined behavior.
2301 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2302 INDEX_TO_CODE_POINT, as that's what it expects.
2303 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2304 * charset.h (DECODE_CHAR): Return int, not unsigned;
2305 this is what was intended anyway, and it avoids undefined behavior.
2306 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2307 integer-overflow issues.
2308 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2309 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2310 where the argument is EMACS_INT, and this behavior is not intended.
2311 * chartab.c (Fmake_char_table, Fset_char_table_range)
2312 (uniprop_get_decoder, uniprop_get_encoder):
2313 Don't assume fixnum fits in int.
2314 * cmds.c (move_point): New function, that does the gist of
2315 Fforward_char and Fbackward_char, but does so while checking
2316 for integer overflow more accurately.
2317 (Fforward_char, Fbackward_char): Use it.
2318 (Fforward_line, Fend_of_line, internal_self_insert)
2319 (internal_self_insert):
2320 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2321 Fix a FIXME, by checking for integer overflow when calculating
2322 target_clm and actual_clm.

2352 (Funencodable_char_position, Fcheck_coding_systems_region)
2353 (get_translation, handle_composition_annotation, consume_chars):
2354 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2355 (consume_chars): Rewrite to not calculate an address outside buffer.
2356 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
2357 Don't access memory outside of the args array.
2358 (Fdefine_coding_system_internal): Check for charset-id overflow.
2359 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
2360 result of ENCODE_CHAR.
2361 * coding.h: Adjust decls to match defn changes elsewhere.

3088 * search.c (Fword_search_regexp, Fword_search_backward)
3089 (Fword_search_forward, Fword_search_backward_lax)
3090 (Fword_search_forward_lax): Move functions to isearch.el
3091 (bug#10145, bug#11381).
3093 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3095 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3097 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3099 * lread.c (init_obarray): Declare Qt and Qnil as special.
3101 2012-05-14 Glenn Morris <rgm@gnu.org>
3103 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3104 Put "libexec" before "bin", for the sake of init_callproc_1.
3106 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3108 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3110 * unexaix.c: Port to more-recent AIX compilers.
3111 (report_error, report_error_1, make_hdr, copy_sym)
3112 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3113 Make arguments const char *, not char *, to avoid violations of C
3114 standard and to fix some AIX warnings reported by Gilles Pion.
3116 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3118 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3119 already have overlays loaded.
3120 (handle_single_display_spec): Before returning without displaying
3121 fringe bitmap, synchronize the bidi iterator with the main display
3122 iterator, by calling iterate_out_of_display_property.
3123 (iterate_out_of_display_property): Detect buffer iteration by
3124 testing that it->string is a Lisp string.
3125 (get_next_display_element): When the current object is exhausted,
3126 and there's something on it->stack, call set_iterator_to_next to
3127 proceed with what's on the stack, instead of returning zero.
3128 (set_iterator_to_next): If called at the end of a Lisp string,
3129 proceed to consider_string_end without incrementing string
3130 position. Don't increment display vector index past the end of
3131 the display vector. (Bug#11417)
3132 (pos_visible_p): Don't report a position visible when move_it_to
3133 stopped at the last line of window, which happens to be scanned
3134 backwards by the bidi iteration. (Bug#11464)
3136 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3138 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3139 and right-margin display specs even if the spec is invalid or we
3140 are on a TTY, and thus unable to display on the fringes.
3141 That's because the text with the property will not be displayed anyway,
3142 so we need to signal to the caller that this is a "replacing"
3143 display spec. This fixes display when the spec is invalid or we
3146 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3148 * unexaix.c (make_hdr): Fix typo in prototype.
3149 This bug broke the build on AIX. Problem reported by Gilles Pion.
3151 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3153 * keyboard.c (kbd_buffer_get_event): Read special events also in
3154 batch mode. (Bug#11415)
3156 2012-05-12 Glenn Morris <rgm@gnu.org>
3158 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3160 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3162 * lisp.mk (lisp): Add newcomment.elc.
3164 2012-05-12 Glenn Morris <rgm@gnu.org>
3166 * Makefile.in (MKDIR_P): New, set by configure.
3167 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3169 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3171 Remove unused function hourglass_started.
3172 * dispextern.h (hourglass_started):
3173 * w32fns.c (hourglass_started):
3174 * xdisp.c (hourglass_started): Remove.
3176 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3178 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3179 Update dependencies.
3181 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3183 * xgselect.c (xg_select): Put maxfds+1 into a var.
3184 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3186 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3188 2012-05-10 Dave Abrahams <dave@boostpro.com>
3190 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3191 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3193 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3195 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3196 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3197 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3198 Initialize xd_registered_buses.
3200 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3202 Untag more efficiently if USE_LSB_TAG.
3203 This is based on a proposal by YAMAMOTO Mitsuharu in
3204 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3205 For an admittedly artificial (nth 8000 longlist) benchmark on
3206 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3207 Emacs's overall text size by 1%.
3208 * lisp.h (XUNTAG): New macro.
3209 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3210 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3211 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3212 * eval.c (Fautoload):
3213 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3214 * frame.h (XFRAME): Use XUNTAG.
3216 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3217 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3218 Remove unportable assumptions about print widths of types like
3220 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3221 intptr_t when converting between pointer and integer, to avoid GCC
3222 warnings about wrong width.
3224 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3226 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3227 stack for each reader_thread, instead of defaulting to 8MB
3228 determined by the linker. This avoids failures in creating
3229 subprocesses on Windows 7, see the discussion in this thread:
3230 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3232 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3234 Fix up display of the *Minibuf-0* buffer in the mini window.
3235 * keyboard.c (read_char): Don't clear the echo area if there's no
3237 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3238 contents of *Minibuf-0*) if there's no message displayed in its stead.
3240 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3242 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3245 2012-05-06 Chong Yidong <cyd@gnu.org>
3247 * lisp.mk (lisp): Update.
3249 2012-05-05 Jim Meyering <meyering@redhat.com>
3251 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3253 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3255 * data.c (PUT_ERROR): New macro.
3256 (syms_of_data): Use it. Add new error type `user-error'.
3257 * undo.c (user_error): New function.
3258 (Fprimitive_undo): Use it.
3259 * print.c (print_error_message): Adjust print style for `user-error'.
3260 * keyboard.c (user_error): New function.
3261 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3263 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3265 Do not limit current-time-string to years 1000..9999.
3266 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3267 (Fcurrent_time_string): Support any year that is supported by the
3268 underlying localtime representation. Don't use asctime, as it
3269 has undefined behavior for years outside the range -999..9999.
3271 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3273 Fix race conditions involving setenv, gmtime, localtime, asctime.
3274 Without this fix, interrupts could mess up code that uses these
3275 nonreentrant functions, since setting TZ invalidates existing
3276 tm_zone or tzname values, and since most of these functions return
3277 pointers to static storage.
3278 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3279 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3280 Grow the critical sections to include not just invoking
3281 localtime/gmtime, but also accessing these functions' results
3282 including their tm_zone values if any, and any related TZ setting.
3283 (format_time_string): Last arg is now struct tm *, not struct tm **,
3284 so that the struct tm is saved in the critical section.
3285 All callers changed. Simplify allocation of initial buffer, partly
3286 motivated by the fact that memory allocation needs to be outside
3287 the critical section.
3289 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3291 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3292 with RESET_INTERVAL.
3294 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3295 Remove duplicated buffer name initialization.
3297 2012-05-02 Jim Meyering <jim@meyering.net>
3299 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3301 * xfns.c (x_window): Use xstrdup (Bug#11375).
3303 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3305 * xdisp.c (pos_visible_p): If already at a newline from the
3306 display string before the 'while' loop, don't walk back the glyphs
3307 from it3.glyph_row. Solves assertion violation when the display
3308 string begins with a newline (egg.el). (Bug#11367)
3310 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3312 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3315 2012-05-01 Glenn Morris <rgm@gnu.org>
3317 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3318 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3319 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3320 All were removed before 23.1.
3322 * dispnew.c: Remove HAVE_LIBNCURSES test;
3323 it is always true on relevant platforms.
3325 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3326 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3328 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3330 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3332 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3333 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3336 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3338 Do not avoid creating empty evaporating overlays (Bug#9642).
3339 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3340 That is, do not delete an evaporating overlay if it becomes
3341 empty after its bounds are adjusted to fit within its buffer.
3342 This fix caused other problems, and I'm reverting it until we get
3343 to the bottom of them.
3345 2012-04-27 Chong Yidong <cyd@gnu.org>
3347 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3349 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3351 * xdisp.c (pos_visible_p): If the window start position is beyond
3352 ZV, start the display from buffer beginning. Prevents assertion
3353 violation in init_iterator when the minibuffer window is scrolled
3356 * window.c (window_scroll_pixel_based): Likewise.
3358 2012-04-27 Chong Yidong <cyd@gnu.org>
3360 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3362 2012-04-27 Glenn Morris <rgm@gnu.org>
3364 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3365 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3367 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3369 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3370 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3372 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3374 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3375 display element, check also the underlying string or buffer
3376 character. (Bug#11341)
3378 * w32menu.c: Include w32heap.h.
3379 (add_menu_item): If the call to AppendMenuW (via
3380 unicode_append_menu) fails, disable Unicode menus only if we are
3381 running on Windows 9X/Me.
3383 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3385 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3386 (xgetint): Add missing shift for LSB tags.
3388 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3390 * keyboard.c (read_char): Don't wipe echo area for select window
3391 events: These might get delayed via `mouse-autoselect-window'
3394 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3396 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3397 manipulation of :loaded-from data.
3399 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3401 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3402 now a cons (bug#11311).
3404 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3406 Do not create empty overlays with the evaporate property (Bug#9642).
3407 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3408 if it becomes empty after its bounds are adjusted to fit within
3409 its buffer. Without this fix, in a nonempty buffer (let ((o
3410 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3411 yields an empty overlay that has the evaporate property, which is
3412 not supposed to happen.
3414 Fix minor GTK3 problems found by static checking.
3415 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3416 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3417 (struct _EmacsFixedClass, emacs_fixed_get_type):
3418 Move decls here from emacsgtkfixed.h, since they needn't be public.

3420 (emacs_fixed_class_init): Omit unused local.
3421 (emacs_fixed_child_type): Remove; unused.

3423 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3424 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
3425 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3426 (EMACS_FIXED_GET_CLASS): Remove; unused.
3427 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
3429 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
3430 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3432 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3434 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3435 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3436 (__malloc_size_t, __malloc_ptrdiff_t):
3437 Remove. All uses removed, replaced by the definiens if needed,
3438 since we can assume C89 or better now.
3439 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
3440 (protect_malloc_state, align, get_contiguous_space)
3441 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

3447 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
3448 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3449 Define using prototypes, not old style.
3450 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3451 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
3452 (align): Don't assume that signed integer overflow wraps around.
3453 Omit unused local var.
3454 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
3455 (_free_internal_nolock, memalign, mallochook, reallochook):
3456 Omit no-longer-needed casts.
3457 (valloc): Use getpagesize, not __getpagesize.
3458 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
3459 (struct hdr): The 'magic' member is now size_t, not unsigned long.
3461 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
3463 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
3465 Move functions from C to Lisp. Make non-blocking method calls
3466 the default. Implement further D-Bus standard interfaces.
3468 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
3469 (QCdbus_request_name_allow_replacement)
3470 (QCdbus_request_name_replace_existing)

3500 (xd_read_queued_messages): Obey new structure of Vdbus_registered_buses.
3501 (Vdbus_compiled_version, Vdbus_runtime_version)
3502 (Vdbus_message_type_invalid, Vdbus_message_type_method_call)
3503 (Vdbus_message_type_method_return, Vdbus_message_type_error)

3508 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3510 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
3511 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
3512 Do not assume ptrdiff_t is the same width as 'int'.
3514 * alloc.c: Handle unusual debugging option combinations.
3515 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
3516 since the two debugging options are incompatible.
3517 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
3519 (mem_init, mem_insert, mem_insert_fixup):
3520 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
3521 (NEED_MEM_INSERT): Remove; no longer needed.
3523 2012-04-22 Leo Liu <sdl.web@gmail.com>
3525 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
3527 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3529 * sysdep.c [__FreeBSD__]: Minor cleanups.
3530 (list_system_processes, system_process_attributes) [__FreeBSD__]:
3531 Use Emacs indenting style more consistently. Avoid some casts.
3532 Use 'double' consistently rather than mixing 'float' and 'double'.
3534 2012-04-21 Eduard Wiebe <usenet@pusto.de>
3536 * sysdep.c (list_system_processes, system_process_attributes):
3537 Add implementation for FreeBSD (Bug#5243).

3550 * print.c (print_preprocess): Only check print_depth if print-circle
3552 (print_object): Check for cycles even when print-circle is nil and
3553 print-gensym is t, but only check print_depth if print-circle is nil.
3555 2012-04-20 Chong Yidong <cyd@gnu.org>
3557 * process.c (wait_reading_process_output): If EIO occurs on a pty,
3558 set the status to "failed" and ensure that sentinel is run.
3560 2012-04-20 Glenn Morris <rgm@gnu.org>

3571 row, return zero immediately.
3572 (try_cursor_movement): If inside continuation line, don't back up
3573 farther than the first row after the header line, if any.
3574 Don't consider the header-line row as "partially visible", even if
3575 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
3577 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

3612 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
3613 New extern decls, to avoid calling undeclared functions.
3614 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3615 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3616 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
3617 (NEED_MEM_INSERT): New macro.
3618 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
3619 Remove one incorrect comment and fix another.

3633 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
3634 Remove decls. This fixes an "It stinks!".
3636 * alloc.c (which_symbols): Fix alignment issue / type clash.
3638 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
3640 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
3641 (struct Lisp_Misc_Any): Likewise.

3653 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
3654 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
3655 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
3656 * s/netbsd.h, s/sol2-6.h:
3657 Remove definition of GC_MARK_STACK, since the default now works.
3658 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3659 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3660 no longer the default.
3661 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3663 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3665 * lread.c (lisp_file_lexically_bound_p):

3686 2012-04-11 Daniel Colascione <dancol@dancol.org>
3688 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3689 against is gone. It's better to use vfork now so that when Cygwin
3690 gains a new, working vfork, we use it automatically (bug#10398).
3692 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

3710 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
3712 * w32.c (w32_delayed_load): Record the full path of the library
3713 being loaded (bug#10424).
3715 2012-04-09 Glenn Morris <rgm@gnu.org>
3717 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3718 not just in the obarray, before snarfing them. (Bug#11036)
3720 * Makefile.in ($(leimdir)/leim-list.el):
3721 Pass EMACS rather than BUILT_EMACS.

3730 Add convenience `GNUTLS_LOG2i' macro.
3732 * gnutls.c (gnutls_log_function2i): Convenience log function.
3733 (emacs_gnutls_read): Use new log functions,
3734 `gnutls_handshakes_tried' process member, and

3736 attempts per process (connection).
3738 2012-04-09 Chong Yidong <cyd@gnu.org>

3745 * minibuf.c (Fread_variable): Callers changed.
3747 2012-04-09 Eli Zaretskii <eliz@gnu.org>
3749 * xdisp.c (set_cursor_from_row): If the display string appears in
3750 the buffer at position that is closer to point than the position
3751 after the display string, display the cursor on the first glyph of
3752 the display string. Fixes cursor display when a 'display' text
3753 property immediately follows invisible text. (Bug#11094)
3755 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
3757 composite.c: use 'double' consistently
3758 * composite.c (get_composition_id): Use 'double' consistently
3759 instead of converting 'float' to 'double' and vice versa; this is
3760 easier to understand and avoids a GCC warning.
3762 2012-04-09 Glenn Morris <rgm@gnu.org>
3764 * Makefile.in: Generate leim-list with bootstrap-emacs, in
3765 preparation for dumping it with emacs. (Bug#4789)

3787 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
3788 (mark_memory): Mark Lisp_Objects only if pointers might hide in
3789 objects, as mark_maybe_pointer will catch them otherwise.
3790 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
3791 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
3793 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
3795 Fix typo that broke non-Windows builds.
3796 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

3806 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
3807 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
3808 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
3809 [!WINDOWSNT]: New macros.
3810 (init_libxml2_functions, libxml2_loaded_p): New functions.
3811 (parse_region): Call fn_xmlCheckVersion instead of using the macro
3812 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
3813 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
3814 Calls xmlCleanupParser only if libxml2 was loaded (or statically
3816 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
3817 Call init_libxml2_functions before calling libxml2 functions.
3818 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
3820 * emacs.c: Don't include libxml/parser.h.
3821 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
3822 xmlCleanupParser directly.
3824 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
3826 2012-04-07 Eli Zaretskii <eliz@gnu.org>

3834 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
3835 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3836 about subtle differences between FETCH_CHAR* and STRING_CHAR*
3837 macros related to unification of CJK characters. For the details,
3838 see the discussion following the message here:
3839 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
3841 2012-04-04 Chong Yidong <cyd@gnu.org>
3843 * keyboard.c (Vdelayed_warnings_list): Doc fix.
3845 2012-04-01 Eli Zaretskii <eliz@gnu.org>
3847 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

3855 2012-03-31 Eli Zaretskii <eliz@gnu.org>
3857 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
3858 position we get to after a call to move_it_to fails the
3859 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
3860 only if we wind up in a string from display property. (Bug#11063)
3862 * window.c (Fdelete_other_windows_internal): Invalidate the row
3863 and column information about mouse highlight, so that redisplay
3864 restores it after reallocating the glyph matrices. (Bug#7464)
3866 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
3867 string comes from a `display' text property, use the buffer
3868 position of that property as if we actually saw that position in
3870 (move_it_by_lines): Remove the assertion that
3871 "it->current_x == 0 && it->hpos == 0" which can be legitimately
3872 violated when there's a before-string at the beginning of a line.
3875 2012-03-30 Eli Zaretskii <eliz@gnu.org>
3877 * xdisp.c (append_space_for_newline): If the default face was
3878 remapped, use the remapped face for the appended newline.
3879 (extend_face_to_end_of_line): Use the remapped default face for
3880 extending the face to the end of the line.
3881 (display_line): Call extend_face_to_end_of_line when the default
3882 face was remapped. (Bug#11068)
3884 2012-03-29 Eli Zaretskii <eliz@gnu.org>

3908 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
3910 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
3912 2012-03-25 Kenichi Handa <handa@m17n.org>
3914 * dispextern.h (struct glyph): Change the bit length of
3915 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
3917 2012-03-24 Eli Zaretskii <eliz@gnu.org>
3919 * s/ms-w32.h (tzname): Include time.h before redirecting to
3920 _tzname. Fixes the MSVC build. (Bug#9960)
3922 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
3924 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
3927 * xterm.c (XTread_socket): Only modify handling_signal if
3928 !SYNC_INPUT. (Bug#11080)
3930 2012-03-23 Eli Zaretskii <eliz@gnu.org>
3932 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
3933 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
3934 when fetching a multibyte character consumes more bytes than
3935 CHAR_BYTES returns, due to unification of CJK characters in
3936 string_char. (Bug#11073)
3938 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
3940 * process.c (wait_reading_process_output): Handle pty disconnect
3941 by refraining from sending oneself a SIGCHLD (bug#10933).

3950 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
3952 2012-03-21 Chong Yidong <cyd@gnu.org>
3954 * xfaces.c (Vface_remapping_alist): Doc fix.
3956 2012-03-20 Eli Zaretskii <eliz@gnu.org>
3958 * w32proc.c (Fw32_set_console_codepage)
3959 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

3970 it fit in a valid range (Bug#11003).
3972 2012-03-18 Eli Zaretskii <eliz@gnu.org>
3974 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
3975 that is not from display property, accept the row as a "cursor
3976 row" if one of the string's character has a non-nil `cursor'
3977 property. Fixes cursor positioning when there are newlines in
3978 overlay strings, e.g. in icomplete.el. (Bug#11035)
3980 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
3982 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

3986 * eval.c (inhibit_lisp_code): Rename from
3987 inhibit_window_configuration_change_hook; move from window.c.
3989 * xfns.c (unwind_create_frame_1, Fx_create_frame):
3990 * window.c (run_window_configuration_change_hook)
3991 (syms_of_window): Callers changed.
3993 2012-03-11 Chong Yidong <cyd@gnu.org>
3995 * keymap.c (Fkey_description): Doc fix (Bug#9700).
3997 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).

4002 is visible (Bug#10955).
4004 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
4006 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4008 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4010 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4011 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4014 2012-03-03 Glenn Morris <rgm@gnu.org>
4016 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

4029 * buffer.c (buffer-list-update-hook): Doc fix.
4031 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4033 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4034 push_it before setting up the iterator for the first overlay
4035 string, even if we have an empty string loaded.
4036 (next_overlay_string): If there's an empty string on the iterator
4037 stack, pop the stack. (Bug#10903)
4039 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4041 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4042 Suggested by Stefan Monnier in
4043 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4044 * alloc.c (widen_to_Lisp_Object): New static function.
4045 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4046 and widening them to Lisp_Objects. This would work even if
4047 USE_LSB_TAG is defined and wide integers are used, which might
4048 happen in a future version of Emacs.
4050 2012-02-25 Chong Yidong <cyd@gnu.org>
4052 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

4066 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4067 call when setting menu-bar-lines and tool-bar-lines parameters.
4068 (unwind_create_frame_1): New helper function.
4070 * window.c (inhibit_window_configuration_change_hook): New var.
4071 (run_window_configuration_change_hook): Obey it.
4072 (syms_of_window): Initialize it.
4074 2012-02-22 Chong Yidong <cyd@gnu.org>

4089 when computing $valmask.
4091 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4092 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4093 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4094 It's useless in that case, and it can cause problems on hosts
4095 that allocate halves of EMACS_INT values separately.
4096 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4097 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4098 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4099 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4100 it avoids undefined behavior on hosts where shifting right by more
4101 than the word width has undefined behavior.
4103 2012-02-19 Chong Yidong <cyd@gnu.org>
4105 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4106 (Funhandled_file_name_directory, Ffile_name_as_directory)

4146 as that creates a dangerous corner case.
4148 * window.c (Fdelete_window_internal): Invalidate the mouse
4149 highlight (Bug#9904).
4151 2012-02-12 Glenn Morris <rgm@gnu.org>

4181 2012-02-07 Chong Yidong <cyd@gnu.org>
4183 * buffer.c (Fbuffer_local_variables)
4184 (buffer_lisp_local_variables): Handle unbound vars correctly;
4185 don't let Qunbound leak into Lisp.
4187 2012-02-07 Glenn Morris <rgm@gnu.org>
4189 * image.c (Fimagemagick_types): Doc fix.
4191 * image.c (imagemagick-render-type): Change it from a lisp object

4227 * character.c (char_width): Return EMACS_INT, not int.
4228 (char_width, c_string_width): Check for overflow when
4229 computing the width; this is possible now that individual
4230 characters can have unbounded width. Problem introduced
4231 by merge from Emacs 23 on 2012-01-19.

4373 (Fmake_directory_internal): Use it.

4903 behave as if the cursor position were at the window margin.
4905 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
4906 and the cursor position is out of bounds, behave as if the cursor

4937 * dispnew.c (verify_row_hash): Call row_hash for computing the
4938 hash code of a row, instead of duplicating code from xdisp.c.
4940 * dispextern.h (row_hash): Add prototype.
4942 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
4944 * frame.c (delete_frame): Don't delete the terminal when the last

5099 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
5100 This is also needed for porting to any host where GC_MARK_STACK is
5101 not GC_MAKE_GCPROS_NOOPS.
5102 (which_symbols): Use it.
5104 2011-11-07 Kenichi Handa <handa@m17n.org>

5125 (window_box_width, window_box_left, window_box_left_offset)
5126 (window_box_right, window_box_right_offset): Declare extern.
5127 Otherwise, these inline functions do not conform to C99 and
5128 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5129 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5130 * intervals.c (adjust_intervals_for_insertion)
5131 (adjust_intervals_for_deletion): Now extern, because otherwise the
5132 extern inline functions 'offset_intervals' couldn't refer to it.
5133 (static_offset_intervals): Remove.
5134 (offset_intervals): Rewrite using the old contents of
5135 static_offset_intervals. The old version didn't conform to C99
5136 because an extern inline function contained a reference to an
5137 identifier with static linkage.

5449 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5450 * editfns.c: Rewrite current-time-zone so that it invokes
5451 the equivalent of (format-time-string "%Z") to get the time zone name.
5452 This fixes a bug when the time zone name contains characters that
5453 need converting from the system time locale to Emacs internal format.
5454 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5455 that patch fixed format-time-string to do the conversion, but
5456 I forgot to fix current-time-zone.
5457 (format_time_string): New function, containing most of
5458 what Fformat_time_string used to contain.

5468 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5470 * xdisp.c (start_display): If the character at POS is displayed
5471 via a display vector, reset IT->current.dpvec_index to zero.
5472 (try_window_reusing_current_matrix): If a line ends in a display
5473 vector or the next line starts in a display vector, continue
5474 redrawing the window even though the character position of
5475 start_row was reached.
5478 2011-10-18 Chong Yidong <cyd@gnu.org>
5480 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5481 with nobreak-char-display too.
5483 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5485 Fix part 3 of bug#9771.
5486 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5487 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5488 non-neutral characters if the current character is a paragraph
5489 separator (a.k.a. Newline). This avoids running the same
5490 expensive loop twice, once when we consume the preceding newline
5491 and the other time when the line actually needs to be displayed.
5492 Avoid the loop when we see neutrals on the base embedding level
5493 following a character whose directionality is the same as the
5494 paragraph's. This avoids running the expensive loop when a line
5495 ends in a long sequence of neutrals, like control characters.
5496 Add assertion against STRONG_AL type. Slightly rearrange code
5497 that determines the type of a neutral given the first non-neutral
5499 (bidi_level_of_next_char): Set next_en_pos to zero when
5500 invalidating its info.
5502 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5504 * xdisp.c (push_display_prop): Determine whether to record string
5505 or buffer position by IT->string, not by IT->method. Allow
5506 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5507 (move_it_vertically_backward): Don't look for character position
5508 immediately after the newline when in a continuation line.
5511 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5513 * window.c (coordinates_in_window): Rewrite and delabelize
5514 vertical border check. (Bug#5357) (Bug#9618)
5516 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5518 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5519 errors in XSetWindowBorder (bug#9310).
5521 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5523 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5524 avoid crash when xmalloc overrun checking is enabled.
5526 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5528 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5529 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5530 cursor motion with <left> and <right> arrow keys.
5532 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5533 some callers set that themselves.
5535 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5537 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5538 display string and the previous row comes from the same string and
5539 is empty. (Bug#9739) (Bug#9738)
5541 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5543 * doc.c (get_doc_string): Encode file name (bug#9735).
5545 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5547 * bidi.c (bidi_level_of_next_char):
5548 * xdisp.c (get_visually_first_element): Remove old incorrect
5549 comments regarding the Unicode Line Separator character.
5551 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5553 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5555 * alloc.c (Fgc_status): Do not access beyond zombies array
5556 boundary if nzombies > MAX_ZOMBIES.
5557 * alloc.c (dump_zombies): Add missing format specifier.
5559 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5561 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5562 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5564 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5565 Some packages use them to denote characters with modifiers.
5567 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5569 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5570 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5571 matching a pp-number. Rename parameter var to var1.
5573 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5575 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5577 2011-10-08 Glenn Morris <rgm@gnu.org>
5579 * callint.c (Fcall_interactively): Give a more explicit error for the
5580 'c' case with a non-character input. (Bug#8479)
5582 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5584 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5586 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5587 lines that are hscrolled on the left.
5589 * dispnew.c (buffer_posn_from_coords): Account for a possible
5590 presence of header-line. (Bug#4426)
5592 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5594 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5595 Don't advertise functionality which we discourage or doesn't work.
5597 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5599 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5600 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5601 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5602 this makes Emacs dump core during garbage collection on rare
5603 occasions. sizeof is obviously inferior to offsetof here, so
5604 stick with offsetof.
5605 (GC_POINTER_ALIGNMENT): New macro.
5606 (mark_memory): Omit 3rd (offset) arg; caller changed.
5607 Don't assume EMACS_INT alignment is the same as pointer alignment.
5609 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5611 * keyboard.c (read_key_sequence_remapped): New var.
5612 (read_key_sequence): Compute remapping in the right buffer.
5613 (command_loop_1): Use read_key_sequence's remapping directly.
5615 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5617 * dired.c (file_name_completion): Don't expand file name.
5618 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5619 before checking file name handler.
5621 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5622 they've been requested explicitly (bug#9591).
5624 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5626 * keymap.c (Fsingle_key_description): Use make_specified_string
5627 instead of build_string to build string from push_key_description.
5630 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5632 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5633 This fixes a Y2038 bug on 64-bit hosts.
5634 * buffer.c (reset_buffer):
5635 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5636 (Fclear_buffer_auto_save_failure):
5637 Use 0, not -1, to represent an unset failure time, since time_t
5638 might not be signed.
5640 Remove dependency on glibc malloc internals.
5641 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5642 Move back here from lisp.h, but with their new implementations.
5643 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5644 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5645 * charset.c (charset_table_init): New static var.
5646 (syms_of_charset): Use it instead of xmalloc. This removes a
5647 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5648 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5649 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5650 Move back to alloc.c.
5651 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5652 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5654 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5656 * nsterm.m (windowDidResize): Call x_set_window_size only when
5657 ns_in_resize is true. Otherwise set pixelwidth/height and
5658 call change_frame_size (Bug#9628).
5660 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5662 Port --enable-checking=all to Fedora 14 x86-64.
5663 * charset.c (syms_of_charset): Also account for glibc malloc's
5664 internal overhead when calculating the initial malloc maximum.
5666 Port --enable-checking=all to Fedora 14 x86.
5667 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5669 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5670 (overrun_check_realloc, overrun_check_free):
5671 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5672 That way, xmalloc returns a properly-aligned pointer even if
5673 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5674 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5675 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5676 into account when calculating the initial malloc maximum.
5677 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5678 Move here from alloc.c, so that charset.c can use it too.
5679 Properly align; the old code wasn't right for common 32-bit hosts
5680 when configured with --enable-checking=all.
5681 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5682 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5684 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5686 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5689 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5691 * xdisp.c (compute_display_string_end): If there's no display
5692 string at CHARPOS, return -1.
5694 * bidi.c (bidi_fetch_char): When compute_display_string_end
5695 returns a negative value, treat the character as a normal
5696 character not covered by a display string. (Bug#9624)
5698 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5700 * lread.c (Fread_from_string): Fix typo in docstring.
5702 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5704 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5705 newline, reseat the iterator instead of bidi-iterating there one
5706 character at a time. (Bug#9610)
5707 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5708 TO_CHARPOS if the bidi iterator is at base embedding level.
5710 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5712 * lread.c (readevalloop): Use correct code for NBSP.
5713 (read1): Likewise. (Bug#9608)
5715 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5717 * dbusbind.c (Fdbus_register_signal): When service is not
5718 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5720 2011-09-25 Glenn Morris <rgm@gnu.org>
5722 * buffer.c (truncate-lines): Doc fix.
5724 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5726 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5727 (Fset_window_next_buffers): Doc fix.
5729 2011-09-24 Glenn Morris <rgm@gnu.org>
5731 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
5733 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
5735 Fix minor problems found by static checking.
5736 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
5737 * indent.c (Fvertical_motion): Fix == vs = typo.
5739 2011-09-24 Eli Zaretskii <eliz@gnu.org>
5741 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
5742 Default value is now t. Doc fix.
5744 * indent.c (Fvertical_motion): Compute and apply the overshoot
5745 logic when moving up, not only when moving down. Fix the
5746 confusing name and values of the it_overshoot_expected variable;
5747 logic changes accordingly. (Bug#9254) (Bug#9549)
5749 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
5750 CHARPOS is covered by a display string which includes newlines.
5751 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
5752 is covered by a display string with embedded newlines.
5754 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
5756 * dbusbind.c (Fdbus_register_signal): Add match rule to
5757 Vdbus_registered_objects_table. (Bug#9581)
5758 (Fdbus_register_method, Vdbus_registered_objects_table):
5761 2011-09-24 Jim Meyering <meyering@redhat.com>
5763 do not ignore write error for any output size
5764 The previous change was incomplete.
5765 While it makes emacs --batch detect the vast majority of stdout
5766 write failures, errors were still ignored whenever the output size is
5767 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
5768 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
5769 && echo FAIL: ignored write error
5770 FAIL: ignored write error
5771 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
5772 && echo FAIL: ignored write error
5773 FAIL: ignored write error
5774 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
5776 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

5779 non-successfully if a write error occurred on stdout. (Bug#9574)
5781 2011-09-21 Eli Zaretskii <eliz@gnu.org>
5783 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
5786 * dispextern.h (struct it): Update the comment documenting what
5789 2011-09-20 Eli Zaretskii <eliz@gnu.org>
5791 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
5792 a display string, extend search for cursor position to end of row.
5793 (find_row_edges): If the row ends in a newline from a display
5794 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
5795 Handle the case of a display string with multiple newlines.
5796 (Fcurrent_bidi_paragraph_direction): Fix search for previous
5797 non-empty line. Fixes confusing cursor motion with arrow keys at
5798 the beginning of a line that starts with whitespace.

5807 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
5810 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5812 * xdisp.c (display_line): Record maximum and minimum buffer
5813 positions even if no glyphs were produced (e.g., by a zero-width
5814 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
5815 buffer positions that will be removed from the glyph row because
5817 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5818 column is beyond frame width: don't subtract 1 "pixel" when
5819 computing width of the stretch.
5820 (reseat_at_next_visible_line_start): Undo the change made on
5821 2011-09-17 that saved paragraph information and restored it after
5822 the call to `reseat'. (Bug#9545)
5824 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5826 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
5827 and turn window cursor on if cleared (Bug#9415).

5840 Fix minor problem found by static checking.
5841 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
5842 initialized, to pacify gcc -Wuninitialized.
5844 * fileio.c: Report proper errno when syscall falls.
5845 (Finsert_file_contents): Save and restore errno,
5846 so that report_file_error outputs the correct diagnostic.
5847 (Fwrite_region) [CLASH_DETECTION]: Likewise.
5849 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5851 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
5853 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5855 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
5856 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
5858 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5860 * xdisp.c (reseat_at_next_visible_line_start): Keep information
5861 about the current paragraph and restore it after the call to reseat.
5863 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
5864 (bidi_find_paragraph_start): Search back for paragraph beginning
5865 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
5866 (bidi_move_to_visually_next): Only trigger paragraph-related
5867 computations when the last character is a newline or at EOB, not
5868 just any NEUTRAL_B. (Bug#9470)
5870 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
5871 truncated lines if point is covered by a display string. (Bug#9524)
5873 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
5875 * xselect.c: Relax test for outgoing X longs (Bug#9498).
5876 (cons_to_x_long): New function.
5877 (lisp_data_to_selection_data): Use it. Correct the test for
5878 short-versus-long data; it was negated. Break out of vector
5879 loop, for efficiency, when a long datum is discovered.
5881 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
5883 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
5885 2011-09-16 Eli Zaretskii <eliz@gnu.org>
5887 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
5888 GCC PR/17406) by declaring this function with external scope.

5911 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
5912 This occurs when processing a multibyte format.
5913 Problem reported by Wolfgang Jenker.
5915 2011-09-15 Johan Bockgård <bojohan@gnu.org>
5917 * xdisp.c (try_cursor_movement): Only check for exact match if
5918 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
5920 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5922 Remove unused external symbols.

5928 * xterm.c, xterm.h (x_catching_errors): Remove.
5930 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5932 * xselect.c: Use signed conversions more consistently (Bug#9498).
5933 (selection_data_to_lisp_data): Assume incoming selection data are
5934 signed integers, not unsigned. This is to be consistent with
5935 outgoing selection data, which was modified to use signed integers
5936 in as part of the fix to Bug#9196 in response to Jan D.'s comment
5937 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
5938 expects long, not unsigned long.

5942 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
5943 computation of loop end. Reported by Johan Bockgård
5946 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
5948 * frame.c (Fother_visible_frames_p): Function deleted.
5950 2011-09-12 Eli Zaretskii <eliz@gnu.org>
5952 * indent.c (compute_motion): Process display vector front to back
5953 rather than the other way around. (Bug#2496)
5955 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5957 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
5959 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
5961 * minibuf.c (Fread_from_minibuffer): Doc fix.
5963 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5965 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
5966 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
5968 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
5970 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
5971 value for non-existent files.
5973 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5975 * fileio.c (Finsert_file_contents): If the file cannot be opened,
5976 set its "size" to -1. This will set the modtime_size field of
5977 the corresponding buffer to -1, which is what
5978 verify-visited-file-modtime expects for files that do not exist.
5981 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
5983 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
5985 * lisp.h: ... from here. push_key_description is no longer
5986 defined in keyboard.c, so its declaration should not be in
5987 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
5988 logically belongs with push_key_description.
5990 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
5992 * buffer.h: Include <sys/types.h> instead of <time.h>.
5993 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
5994 Problem reported by Herbert J. Skuhra.
5996 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
5998 * xml.c (parse_region): Make the parsing work for
5999 non-comment-starting XML files again (bug#9144).
6001 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6003 * image.c (gif_load): Fix calculation of bottom and right corner.
6006 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6008 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6009 redisplay in small windows.
6011 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6013 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6015 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6017 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6018 Operate on live windows only.
6020 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6022 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6024 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6026 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6027 only under bidi iteration.
6029 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6031 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6033 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6035 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6036 Without this fix, the command to link temacs failed due to an
6037 undefined symbol __builtin_isnan. This is because
6038 /usr/include/iso/math_c99.h #defines isnan(x) to
6039 __builtin_isnan(x), but the bundled gcc, which identifies itself
6040 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6042 * floatfns.c (isnan): #undef, and then #define to a clone of
6044 (Fisnan): Always define, since it's always available now.
6045 (syms_of_floatfns): Always define isnan at the Lisp level.
6047 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6049 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6051 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6053 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6054 The previous code assumed that file offsets (off_t values) fit in
6055 EMACS_INT variables, which is not true on typical 32-bit hosts.
6056 The code messed up by falsely reporting buffer overflow in cases
6057 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6058 when "big" contains more than 2**29 bytes, even though this
6059 inserts just one byte and does not overflow the buffer.
6060 (Finsert_file_contents): Store file offsets as off_t
6061 values, not as EMACS_INT values. Check for overflow when
6062 converting between EMACS_INT and off_t. When checking for
6063 buffer overflow or for overlap, take the offsets into account.
6064 Don't use EMACS_INT for small values where int suffices.
6065 When checking for overlap, fix a typo: ZV was used where
6066 ZV_BYTE was intended.
6067 (Fwrite_region): Don't assume off_t fits into 'long'.
6068 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6070 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6072 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6074 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6076 sprintf-related integer and memory overflow issues (Bug#9412).
6078 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6079 (esprintf, exprintf, evxprintf): New functions.
6080 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6081 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6082 (modify_event_symbol): Do not assume that the length of
6083 name_alist_or_stem is safe to alloca and fits in int.
6084 (Fexecute_extended_command): Likewise for function name and binding.
6085 (Frecursion_depth): Wrap around reliably on integer overflow.
6086 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6087 since some callers pass EMACS_INT values.
6088 (Fsingle_key_description): Don't crash if symbol name contains more
6089 than MAX_ALLOCA bytes.
6090 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6091 (get_minibuffer): Arg is now EMACS_INT, not int.
6092 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6093 (esprintf, exprintf, evxprintf): New decls.
6094 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6096 * dbusbind.c (signature_cat): New function.
6097 (xd_signature, Fdbus_register_signal):
6098 Do not overrun buffer; instead, report string overflow.
6100 * dispnew.c (add_window_display_history): Don't overrun buffer.
6101 Truncate instead; this is OK since it's just a log.
6103 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6104 even if the time zone offset is outlandishly large.
6105 Don't mishandle offset == INT_MIN.
6107 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6108 when creating daemon; the previous buffer-overflow check was incorrect.
6110 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6111 which has the guts of the old verror function.
6113 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6114 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6116 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6117 (font_unparse_xlfd): Don't blindly alloca long strings.
6118 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6119 fits in int, when using sprintf. Use single snprintf to count
6120 length of string rather than counting it via multiple sprintfs;
6121 that's simpler and more reliable.
6122 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6123 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6124 sprintf, in case result does not fit in int.
6126 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6127 (fontset_from_font): Print it.
6129 * frame.c (tty_frame_count): Now printmax_t, not int.
6130 (make_terminal_frame, set_term_frame_name): Print it.
6131 (x_report_frame_params): In X, window IDs are unsigned long,
6132 not signed long, so print them as unsigned.
6133 (validate_x_resource_name): Check for implausibly long names,
6134 and don't assume name length fits in 'int'.
6135 (x_get_resource_string): Don't blindly alloca invocation name;
6136 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6139 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6140 (xg_check_special_colors, xg_set_geometry):
6141 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6143 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6144 Use esprintf, not sprintf, in case result does not fit in int.
6146 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6147 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6148 it as a large positive number.
6149 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6150 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6152 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6153 in case result does not fit in int.
6155 * print.c (float_to_string): Detect width overflow more reliably.
6156 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6157 buffer overrun. Don't assume list length fits in 'int'. Treat
6158 print length of 0 as 0, not as infinity; to be consistent with other
6159 uses of print length in this function. Don't overflow print length
6160 index. Don't assume hash table size fits in 'long', or that
6161 vectorlike size fits in 'unsigned long'.
6163 * process.c (make_process): Use printmax_t, not int, to format
6164 process-name gensyms.
6166 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6168 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6169 to avoid potential buffer overrun.
6171 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6172 if X resource line is longer than 512 bytes.
6174 * xfns.c (x_window): Make sprintf buffer a bit bigger
6175 to avoid potential buffer overrun.
6177 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6179 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6181 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6183 Integer overflow fixes for scrolling, etc.
6184 Without these, Emacs silently mishandles large integers sometimes.
6185 For example, "C-u 4294967297 M-x recenter" was treated as if
6186 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6188 * xdisp.c (try_window_id): Check Emacs fixnum range before
6189 converting to 'int'.
6191 * window.c (window_scroll_line_based, Frecenter):
6192 Check that an Emacs fixnum is in range before assigning it to 'int'.
6193 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6194 values converted from Emacs fixnums.
6195 (Frecenter): Don't wrap around a line count if it is out of 'int'
6196 range; instead, treat it as an extreme value.
6197 (Fset_window_configuration, compare_window_configurations):
6198 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6200 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6201 that can exceed INT_MAX. Check that EMACS_INT value is in range
6202 before assigning it to the (possibly-narrower) index.
6203 (match_limit): Don't assume that a fixnum can fit in 'int'.
6205 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6208 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6209 (Fvertical_motion): Don't wrap around LINES values that don't fit
6210 in 'int'. Instead, treat them as extreme values. This is good
6211 enough for windows, which can't have more than INT_MAX lines anyway.
6213 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6215 * Require libxml/parser.h to avoid compilation warning.
6217 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6219 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6220 since this reportedly can destroy thread storage.
6222 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6224 * syntax.c (find_defun_start): Update all cache variables if
6225 exiting early (Bug#9401).
6227 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6229 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6231 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6232 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6233 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6235 * term.c (tty_append_glyph): New function.
6236 (produce_stretch_glyph): Static function and its prototype deleted.
6238 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6241 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6243 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6244 when checking :margin (Bug#9390).
6245 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6246 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6247 so that the name doesn't mislead. All uses changed.
6249 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6251 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6254 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6256 * xdisp.c (move_it_to): Don't bail out early when reaching
6257 position beyond to_charpos, if we are scanning backwards.
6258 (move_it_vertically_backward): When DY == 0, make sure we get to
6259 the first character in the line after the newline.
6261 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6263 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6264 (ccl_driver): Do not generate an out-of-range pointer.
6265 (Fccl_execute_on_string): Remove unnecessary check for
6266 integer overflow, noted by Stefan Monnier in
6267 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6268 Remove a FIXME that didn't need fixing.
6269 Simplify the newly-introduced buffer reallocation code.
6271 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6273 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6275 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6277 Integer and memory overflow issues (Bug#9196).
6279 * doc.c (get_doc_string): Rework so that
6280 get_doc_string_buffer_size is the actual buffer size, rather than
6281 being 1 less than the actual buffer size; this makes xpalloc more
6284 * image.c (x_allocate_bitmap_record, cache_image):
6285 * xselect.c (Fx_register_dnd_atom):
6286 Simplify previous changes by using xpalloc.
6288 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6289 since either will do and ptrdiff_t is convenient with xpalloc.
6291 * charset.c (charset_table_size)
6292 (struct charset_sort_data.priority): Now ptrdiff_t.
6293 (charset_compare): Don't overflow if priorities differ greatly.
6294 (Fsort_charsets): Don't assume list length fits in int.
6295 Check for size-calculation overflow when allocating sort data.
6296 (syms_of_charset): Allocate an initial charset table that is
6297 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6299 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6301 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6302 The actual value is always <= INT_MAX, and leaving it unsigned made
6303 overflow checking harder.
6305 * dispextern.h (struct glyph_matrix.rows_allocated)
6306 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6307 with xpalloc. The values are still always <= INT_MAX.
6309 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6311 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6312 (SAFE_NALLOCA): New macro.
6314 * region-cache.c (struct boundary.pos, find_cache_boundary)
6315 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6316 (set_cache_region, invalidate_region_cache)
6317 (revalidate_region_cache, know_region_cache, region_cache_forward)
6318 (region_cache_backward, pp_cache):
6319 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6320 so that ptrdiff_t * can be passed to xpalloc.
6321 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6322 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6323 (pp_cache): Don't assume cache_len fits in int.
6324 * region-cache.h: Adjust extern decls to match.
6326 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6327 EMACS_INT, since either will do, for xpalloc.
6329 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6330 (xnmalloc, xnrealloc, xpalloc): New functions.
6332 * bidi.c (bidi_shelve_header_size): New constant.
6333 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6334 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6336 * bidi.c (bidi_cache_shrink):
6337 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6339 Don't update size of array until after memory allocation succeeds,
6340 because xmalloc/xrealloc may not return.
6341 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6342 now that we have proper integer overflow checking.
6343 (record_overlay_string, overlay_strings): Catch overflows when
6344 calculating size of overlay_str_buf.
6346 * callproc.c (Fcall_process): Check for size overflow when
6347 calculating size of args2.
6348 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6349 Normally we prefer signed values, but sticking with ptrdiff_t would
6350 require adding more-complicated checks.
6352 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6353 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6354 Redo buffer-overflow calculations to avoid integer overflow.
6355 Add a FIXME comment where memory seems to be over-allocated.
6357 * character.c (Fstring): Check for size-calculation overflow.
6359 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6360 unnecessary integer overflow. Check for size overflow.
6361 (encode_coding_object): Don't update size until xmalloc succeeds.
6363 * composite.c (get_composition_id): Check for overflow in glyph
6364 length calculations.
6366 Integer and memory overflow fixes for display code.
6367 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6368 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6369 (scrolling_window): Check for overflow in size calculations.
6370 (line_draw_cost, realloc_glyph_pool, add_row_entry):
6371 Don't assume glyph table len fits in int.
6372 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
6373 (row_table_size): Now ptrdiff_t, not int.
6374 (scrolling_window): Avoid overflow in size calculations.
6375 Don't update size until allocation succeeds.
6376 * fns.c (concat): Check for overflow in size calculations.
6377 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
6378 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6379 (NEXT_ALMOST_PRIME_LIMIT): New constant.
6381 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
6382 (get_doc_string): Check for size calculation overflow.
6383 Don't update size until allocation succeeds.
6384 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6385 EMACS_INT, where ptrdiff_t will do.
6386 (Fsubstitute_command_keys): Check for string overflow.
6388 * editfns.c (set_time_zone_rule): Don't assume environment length
6390 (message_length): Now ptrdiff_t, not int.
6391 (Fmessage_box): Don't update size until allocation succeeds.
6392 Don't assume message length fits in int.
6393 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6395 * emacs.c (main): Do not reallocate argv, since there is a null at
6396 the end that can be overwritten, and this way there's no need to
6397 worry about size-calculation overflow.
6398 (sort_args): Check for size-calculation overflow.
6400 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6402 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
6404 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
6405 (x_set_scroll_bar_width, x_figure_window_size):
6406 Check for integer overflow.
6407 (x_set_alpha): Do not assume XINT fits in int.
6409 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6410 This is for the members text_lines, text_cols, total_lines, total_cols,
6411 where the system imposes an 'int' limit.
6413 * fringe.c (Fdefine_fringe_bitmap):
6414 Don't update size until alloc works.
6416 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
6417 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
6419 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
6420 Check for size-calculation overflow.
6421 (get_utf8_string): Use ptrdiff_t, not size_t, where either will

6476 (Fset_match_data): Don't assume list lengths fit in 'int'.
6478 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,

6515 (Fx_change_window_property): Use ptrdiff_t, not int, to count
6516 sizes, since they can exceed INT_MAX in size. Check for size

6526 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
6527 (X_LONG_MIN): New macros.
6528 Use them to make the following changes clearer.
6529 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6530 This change doesn't affect the value now, but it may help remind
6531 future maintainers not to raise the value too much later.
6532 (SELECTION_QUANTUM): Remove, replacing with ...
6533 (selection_quantum): ... new function, which avoids overflow.
6535 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

6553 Don't store size until memory allocation succeeds.
6554 (x_get_window_property): Plug memory leak on memory exhaustion.
6555 Don't double-block input; malloc is safe here. Don't assume 2**34
6556 - 4 fits in unsigned long. Add an xassert to check
6557 XGetWindowProperty overflow. Be more careful about overflow
6558 calculations, and distinguish size from memory overflow better.

6564 in the range -65535 through -1 fit in an X unsigned short.
6565 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6566 result parameters unless successful. Rely on cons_to_unsigned
6567 to report problems with elements; the old code wasn't right anyway.
6568 (x_check_property_data): Check for int overflow; we cannot use
6569 a wider type due to X limits.
6570 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

6602 * lisp.h (hash_lookup, hash_put):
6603 * minibuf.c (Ftest_completion):
6604 Use ptrdiff_t for hash table indexes, not int (which is too
6605 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
6606 32-bit --with-wide-int hosts).

6639 (x_send_scroll_bar_event): Likewise. Check that the size does not
6640 exceed limits imposed by XClientMessageEvent, as well as the usual
6641 ptrdiff_t and size_t limits.
6643 * keyboard.c: Overflow, signedness and related fixes.
6644 (make_lispy_movement): Use same integer type in forward decl
6645 that is used in the definition.
6646 (read_key_sequence, keyremap_step):
6647 Change bufsize argument back to int, undoing my 2011-03-30 change.
6648 We prefer signed types, and int is wide enough here.
6649 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6650 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
6651 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
6652 length, not size_t. Use ptrdiff_t for index, not int.
6653 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
6654 possibility of integer overflow.

6682 Prefer int to unsigned where either will do.
6683 (tiff_handler): New function, combining the cores of the
6684 old tiff_error_handler and tiff_warning_handler.
6685 This function is rewritten to use vsnprintf and thereby avoid
6686 stack buffer overflows. It uses only the features of vsnprintf
6687 that are common to both POSIX and native Microsoft.
6688 (tiff_error_handler, tiff_warning_handler): Use it.
6689 (tiff_load, gif_load, imagemagick_load_image):

6693 the integer types that MagickCropImage accepts. Don't assume
6694 Vimagemagick_render_type has a nonnegative value. Don't assume
6695 size_t fits in 'long'.
6696 (gs_load): Use printmax_t to print the widest integers possible.

6714 accurately, and prefer exact match for point under bidi.
6715 Don't advance `row' beyond the last row of the window.
6717 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6718 into disp_prop; all users changed.
6720 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

6736 positioning on the newline at EOL of R2L text within L2R
6737 paragraph, and vice versa.
6738 (try_cursor_movement): Check continued rows, in addition to
6739 continuation rows. Fixes unwarranted scroll when point enters a
6740 continued line of R2L text within an L2R paragraph, or vice versa.
6741 (cursor_row_p): Consider the case of point being equal to
6742 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

6771 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6772 instead of CHAR_TO_BYTE. Fixes a crash when a completion
6773 candidate is selected by the mouse, and that candidate has a
6774 composed character under the mouse.
6776 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
6777 coordinates reported by pos-visible-in-window-p for a composed

6788 composed buffer positions.
6790 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
6792 * image.c (gif_load): Don't assume that each subimage has the same
6793 dimensions as the base image. Handle disposal method that is
6794 "undefined" by the gif spec (Bug#9335).
6796 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
6798 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

6803 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
6804 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
6805 from an Org mode buffer to a Speedbar frame.
6807 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
6808 a composition, take its buffer position from IT->cmp_it.charpos.
6809 Fixes cursor positioning at the beginning of a line that begins
6810 with a composed character.
6812 2011-08-18 Eli Zaretskii <eliz@gnu.org>
6814 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
6815 character bidirectional type, use STRONG_L instead. Fixes crashes
6816 in a buffer produced by `describe-categories'.
6818 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
6819 members before the level stack, so they would be saved and
6820 restored when copying iterator state. Fixes incorrect reordering
6821 around TABs covered by display properties.
6823 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

6882 biditype.h and bidimirror.h.
6884 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
6885 coordinates of the iterator when restoring from ppos_it.
6888 2011-08-14 Kenichi Handa <handa@m17n.org>
6890 * process.c (create_process): Call setup_process_coding_systems
6891 after the pid of the process is set to -1 (Bug#8162).
6893 2011-08-14 Eli Zaretskii <eliz@gnu.org>
6895 * xdisp.c (move_it_in_display_line_to): Don't invoke
6896 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
6897 ppos_it. Fixes vertical cursor motion when line beginning is
6898 covered by an image. (Bug#9296)
6900 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
6902 * nsterm.h (ns_run_ascript): Declare.
6903 (NSAPP_DATA2_RUNASSCRIPT): Define.
6905 * nsfns.m (as_script, as_result, as_status): New static variables.
6906 (ns_run_ascript): New function.
6907 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
6908 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
6909 the event loop. Get status from as_status (Bug#7276).
6911 * nsterm.m (sendEvent): If event is NSApplicationDefined and
6912 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
6913 the event loop (Bug#7276).
6915 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
6917 * gnutls.c (QCgnutls_bootprop_priority)
6918 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
6919 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
6920 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
6921 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
6922 (QCgnutls_bootprop_verify_hostname_error)
6923 (QCgnutls_bootprop_callbacks_verify): Rename from
6924 Qgnutls_bootprop_..., all uses changed.
6926 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
6929 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
6931 * xfaces.c (Qframe_set_background_mode): Now static.
6932 * dispextern.h (Qframe_set_background_mode): Remove decl.
6934 * process.c (Fnetwork_interface_info): Declare local only if needed.
6936 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
6938 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
6939 (Fnetwork_interface_list): Allocate in increments of bytes instead
6940 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
6941 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
6943 (struct ifflag_def): notrailers is smart on OSX.
6944 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
6945 Get hardware address with getifaddrs if available.
6947 2011-08-12 Eli Zaretskii <eliz@gnu.org>
6949 * xdisp.c (iterate_out_of_display_property): xassert that
6950 IT->position is set to within IT->object's boundaries. Break from
6951 the loop as soon as EOB is reached; avoids infloops in redisplay
6952 when IT->position is set up wrongly due to some bug.
6953 Set IT->current to match the bidi iterator unconditionally.
6954 (push_display_prop): Allow GET_FROM_STRING as IT->method on
6955 entry. Force push_it to save on the stack the current
6956 buffer/string position, to be restored by pop_it. Fix flags in
6957 the iterator structure wrt the object coming from a display
6958 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
6959 properties. (Bug#9284)
6961 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
6963 * fontset.c (fontset_get_font_group): Add proper type checks.
6966 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

6969 and LC_VERSION_MIN_MACOSX.
6970 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
6971 (dump_it) [LC_FUNCTION_STARTS]: Use it.
6973 2011-08-08 Eli Zaretskii <eliz@gnu.org>
6975 * xdisp.c (forward_to_next_line_start): Allow to use the
6976 no-display-properties-and-no-overlays under bidi display.
6977 Set disp_pos in the bidi iterator to avoid searches for display
6978 properties and overlays.
6980 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
6982 * editfns.c (Fset_time_zone_rule): Document relationship with the
6985 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
6986 the font entity extracted from the cache (Bug#8109).
6988 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
6990 * composite.c (autocmp_chars): Don't reset point. That is done by
6991 restore_point_unwind (Bug#5984).
6993 2011-08-07 Juri Linkov <juri@jurta.org>
6995 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
6996 to show the arg `TIME' instead of `TIMEVAL'.
6998 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7000 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7001 display property strides EOL and includes a newline, as in
7002 longlines-mode. (Bug#9254)
7003 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7004 word-wrap under bidirectional display. (Bug#9224)
7006 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7007 is non-zero, even if the data buffer is NULL. Fixes a crash in
7008 vertical-motion with longlines-mode. (Bug#9254)
7010 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7012 * bidi.c <bidi_cache_total_alloc>: Now static.
7013 (bidi_initialize): Initialize bidi_cache_total_alloc.
7015 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7018 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7019 amount allocated this far in `bidi_cache_total_alloc'.
7020 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7021 non-zero, only free the data buffer without restoring the cache
7022 contents. All callers changed.
7024 * dispextern.h (bidi_unshelve_cache): Update prototype.
7026 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7027 (move_it_in_display_line, move_it_to)
7028 (move_it_vertically_backward, move_it_by_lines): Replace the call
7029 to xfree to an equivalent call to bidi_unshelve_cache.
7030 (move_it_in_display_line_to): Fix logic of returning
7031 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7033 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7035 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7036 came from a string character with a `cursor' property. (Bug#9229)
7038 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7040 * Makefile.in (LIB_PTHREAD): New variable.
7041 (LIBES): Add LIB_PTHREAD (Bug#9216).
7043 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7044 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
7046 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
7048 * regex.c (re_iswctype): Remove some redundant boolean conversions.
7050 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7052 * xterm.c (x_find_topmost_parent): New function.
7053 (x_set_frame_alpha): Find topmost parent window with
7054 x_find_topmost_parent and set the property there also (bug#9181).
7055 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
7057 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
7059 * callproc.c (Fcall_process): Avoid vfork clobbering
7060 the local vars buffer, coding_systems, current_dir.
7062 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
7064 * keymap.c (Fmake_composed_keymap): Move to subr.el.
7066 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
7068 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
7069 so that it is not optimized away.
7071 * xdisp.c (compute_display_string_pos): Remove unused local.
7073 2011-08-02 Eli Zaretskii <eliz@gnu.org>
7075 Fix slow cursor motion and scrolling in large buffers with
7076 selective display, like Org Mode buffers. (Bug#9218)
7078 * dispextern.h (struct bidi_it): New member disp_prop_p.
7080 * xdisp.c: Remove one-slot cache of display string positions.
7081 (compute_display_string_pos): Accept an additional argument
7082 DISP_PROP_P; callers changed. Scan at most 5K characters forward
7083 for a display string or property. If found, set DISP_PROP_P
7086 * bidi.c (bidi_fetch_char): Accept an additional argument
7087 DISP_PROP_P, and pass it to compute_display_string_pos.
7088 Only handle text covered by a display string if DISP_PROP_P is returned
7089 non-zero. All callers of bidi_fetch_char changed.
7091 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
7093 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
7095 2010-12-03 Don March <don@ohspite.net>
7097 * keymap.c (Fdefine_key): Fix non-prefix key error message when
7098 last character M-[char] is translated to ESC [char] (bug#7541).
7100 2011-08-02 Kenichi Handa <handa@m17n.org>
7102 * lisp.h (uniprop_table): Extern it.
7104 * chartab.c (uniprop_table): Make it non-static.
7106 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7108 * xdisp.c (forward_to_next_line_start): Accept additional argument
7109 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7111 (reseat_at_next_visible_line_start): Use the bidi iterator state
7112 returned by forward_to_next_line_start to restore the state of
7113 it->bidi_it after backing up to previous newline. (Bug#9212)
7115 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7117 * regex.c (re_comp): Protoize.
7118 (re_exec): Fix return type.
7119 (regexec): Fix type of `ret'. (Bug#9203)
7121 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7123 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7124 This is needed if max-image-size is a floating-point number.
7126 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7128 * print.c (print_object): Print empty symbol as ##.
7130 * lread.c (read1): Read ## as empty symbol.
7132 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7134 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7135 setting frame foreground color (Bug#9175).
7136 (x_set_background_color): Likewise.
7138 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7139 contents (Bug#9176).
7140 (EmacsTooltip -init): Remove bezels and add shadows to
7143 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7144 or scroll bar (Bug#8470).
7146 * nsfont.m (nsfont_open): Remove assignment to voffset and
7147 unnecessary vars hshink, expand, hd, full_height, min_height.
7148 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7150 * nsterm.h (nsfont_info): Remove voffset field.
7152 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7154 Implement strike-through and overline on NextStep (Bug#8863).
7156 * nsfont.m (nsfont_open): Use underline position provided by font,
7157 instead of hard-coded value of 2.
7158 (nsfont_draw): Call ns_draw_text_decoration instead.
7160 * nsterm.h: Add declaration for ns_draw_text_decoration.
7162 * nsterm.m (ns_draw_text_decoration): New function for drawing
7163 underline, overline, and strike-through.
7164 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
7165 ns_draw_text_decoration. Change treatment of cursor drawing to
7166 accommodate underlining, etc.
7168 2011-07-28 Eli Zaretskii <eliz@gnu.org>
7170 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7173 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7175 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7176 Without this fix, if a signal arrives just after memory fills up,
7177 'malloc' might be invoked reentrantly.
7179 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7180 In other words, assume that every image size is allowed, on non-X
7181 hosts. This assumption is probably wrong, but it lets Emacs compile.
7183 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7185 * regex.c (re_iswctype): Convert return values to boolean.
7187 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7189 * xdisp.c (compute_display_string_pos): Don't use cached display
7190 string position if the buffer had its restriction changed.
7193 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7195 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7197 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7199 Integer signedness and overflow and related fixes. (Bug#9079)
7201 * bidi.c: Integer size and overflow fixes.
7202 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7203 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7204 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7205 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7206 (bidi_find_other_level_edge):
7207 Use ptrdiff_t instead of EMACS_INT where either will do.
7208 This works better on 32-bit hosts configured --with-wide-int.
7209 (bidi_cache_ensure_space): Check for size-calculation overflow.
7210 Use % rather than repeated addition, for better worst-case speed.
7211 Don't set bidi_cache_size until after xrealloc returns, because it
7213 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7214 (bidi_cache_ensure_space): Also check that the bidi cache size
7215 does not exceed that of the largest Lisp string or buffer. See Eli
7216 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7218 * alloc.c (__malloc_size_t): Remove.
7219 All uses replaced by size_t. See Andreas Schwab's note
7220 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7222 * image.c: Improve checking for integer overflow.
7223 (check_image_size): Assume that f is nonnull, since
7224 it is always nonnull in practice. This is one less thing to
7225 worry about when checking for integer overflow later.
7226 (x_check_image_size): New function, which checks for integer
7227 overflow issues inside X.
7228 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7229 This removes the need for a memory_full check.
7230 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7231 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7232 (xbm_read_bitmap_data): Change locals back to 'int', since
7233 their values must fit in 'int'.
7234 (xpm_load_image, png_load, tiff_load):
7235 Invoke x_create_x_image_and_pixmap earlier,
7236 to avoid much needless work if the image is too large.
7237 (tiff_load): Treat overly large images as if
7238 x_create_x_image_and_pixmap failed, not as malloc failures.
7239 (gs_load): Use x_check_image_size.
7241 * gtkutil.c: Omit integer casts.
7242 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7243 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7245 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7247 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7248 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7249 would wrongly return t on a 64-bit host.
7251 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7252 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7253 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7254 and therefore cause GCC to emit a bogus diagnostic in some cases.
7256 * image.c: Integer signedness and overflow and related fixes.
7257 This is not an exhaustive set of fixes, but it's time to
7258 record what I've got.
7259 (lookup_pixel_color, check_image_size): Remove redundant decls.
7260 (check_image_size): Don't assume that arbitrary EMACS_INT values
7261 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7262 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7263 (tiff_load, imagemagick_load_image):
7264 Check for overflow in size calculations.
7265 (x_create_x_image_and_pixmap): Remove unnecessary test for
7266 xmalloc returning NULL; that can't happen.
7267 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7268 (xpm_color_bucket): Use better integer hashing function.
7269 (xpm_cache_color): Don't possibly over-allocate memory.
7270 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7271 (gif_memory_source):
7272 Use ptrdiff_t, not int or size_t, to record sizes.
7273 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7274 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7275 either works, as we prefer signed integers.
7276 (tiff_read_from_memory, tiff_write_from_memory):
7277 Return tsize_t, not size_t, since that's what the TIFF API wants.
7278 (tiff_read_from_memory): Don't fail simply because the read would
7279 go past EOF; instead, return a short read.
7280 (tiff_load): Omit no-longer-needed casts.
7281 (Fimagemagick_types): Don't assume size fits into 'int'.
7283 Improve hashing quality when configured --with-wide-int.
7284 * fns.c (hash_string): New function, taken from sxhash_string.
7285 Do not discard information about ASCII character case; this
7286 discarding is no longer needed.
7287 (sxhash-string): Use it. Change sig to match it. Caller changed.
7288 * lisp.h: Declare it.
7289 * lread.c (hash_string): Remove, since we now use fns.c's version.
7290 The fns.c version returns a wider integer if --with-wide-int is
7291 specified, so this should help the quality of the hashing a bit.
7293 * emacs.c: Integer overflow minor fix.
7294 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7295 Define only if GNU_LINUX.
7296 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7298 * dispnew.c: Integer signedness and overflow fixes.
7299 Remove unnecessary forward decls, that were a maintenance hassle.
7300 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7302 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7303 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7304 (prepare_desired_row, line_draw_cost):
7305 Use int, not unsigned, where either works.
7306 (save_current_matrix, restore_current_matrix):
7307 Use ptrdiff_t, not size_t, where either works.
7308 (init_display): Check for overflow more accurately, and without
7309 relying on undefined behavior.
7311 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7312 Remove, replacing with the new symbols in lisp.h. All uses changed.
7313 * fileio.c (make_temp_name):
7314 * filelock.c (lock_file_1, lock_file):
7315 * xdisp.c (message_dolog):
7316 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7317 Use pMd etc. instead.
7318 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7319 replacing the pWIDE etc. symbols removed from editfns.c.
7321 * keyboard.h (num_input_events): Now uintmax_t.
7322 This is (very slightly) less likely to mess up due to wraparound.
7325 * buffer.c: Integer signedness fixes.
7326 (alloc_buffer_text, enlarge_buffer_text):
7327 Use ptrdiff_t rather than size_t when either will do, as we prefer
7330 * alloc.c: Integer signedness and overflow fixes.
7331 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7332 (__malloc_size_t): Default to size_t, not to int.
7333 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7334 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7335 Prefer ptrdiff_t to size_t when either would do, as we prefer
7337 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7338 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7339 Now const. Initialize with values that are in range even if char
7341 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7342 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7343 These functions do the right thing with sizes > 2**32.
7344 (check_depth): Now ptrdiff_t, not int.
7345 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7346 Adjust to new way of storing sizes. Check for size overflow bugs
7348 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7349 slightly wrong anyway, as it missed one instance of
7350 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7351 (refill_memory_reserve): Omit needless cast to size_t.
7352 (mark_object_loop_halt): Mark as externally visible.
7354 * xselect.c: Integer signedness and overflow fixes.
7355 (Fx_register_dnd_atom, x_handle_dnd_message):
7356 Use ptrdiff_t, not size_t, since we prefer signed.
7357 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7358 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7359 x_dnd_atoms_size and x_dnd_atoms_length.
7361 * doprnt.c: Prefer signed to unsigned when either works.
7363 * doprnt.c (doprnt):
7365 * xdisp.c (vmessage):
7366 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7367 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7368 prefer signed arithmetic to avoid comparison confusion.
7369 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7370 but is a bit tricky.
7372 Assume freestanding C89 headers, string.h, stdlib.h.
7373 * data.c, doprnt.c, floatfns.c, print.c:
7374 Include float.h unconditionally.
7375 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7376 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7377 * regex.c: Likewise for stddef.h, string.h.
7378 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7379 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7380 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7381 (STDC_HEADERS): Remove obsolete defines.
7382 * sysdep.c: Include limits.h unconditionally.
7384 Assume support for memcmp, memcpy, memmove, memset.
7385 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7386 * regex.c (memcmp, memcpy):
7387 Remove; we assume C89 now.
7389 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7390 (__malloc_safe_bcopy): Remove; no longer needed.
7392 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7393 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7394 well either way, and we prefer signed to unsigned.
7396 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7398 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7399 closes the connection while we're reading (bug#9182).
7401 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7403 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7404 are specified (Bug#9168).
7406 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7408 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7409 Found by GCC static checking and --with-wide-int on a 32-bit host.
7411 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7413 * xdisp.c (compute_display_string_pos): Fix logic of caching
7414 previous display string position. Initialize cached_prev_pos to
7415 -1. Fixes slow-down at the beginning of a buffer.
7417 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7419 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7420 for attrs[LFACE_FONTSET_INDEX].
7422 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7424 * xml.c (parse_region): Remove unused local
7425 that was recently introduced.
7427 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7429 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7430 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7432 * xdisp.c (move_it_in_display_line_to): Record the best matching
7433 position for TO_CHARPOS while scanning the line, and restore it on
7434 exit if none of the characters scanned was an exact match.
7435 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7436 when exact match is impossible due to invisible text, and the
7437 lines are truncated.
7439 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7441 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7444 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7446 Fix a significant slow-down of cursor motion with C-n, C-p,
7447 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7448 auto-repeat under bidi redisplay in fontified buffers.
7449 * xdisp.c (compute_stop_pos_backwards): New function.
7450 (next_element_from_buffer): Call compute_stop_pos_backwards to
7451 find a suitable prev_stop when we find ourselves before
7453 (reseat): Don't look for prev_stop, as that could mean a very long
7455 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7456 <cached_disp_overlay_modiff>: Cache for last found display string
7458 (compute_display_string_pos): Return the cached position if asked
7459 about the same buffer in the same area of character positions, and
7460 the buffer wasn't changed since the time the display string
7461 position was cached.
7463 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7465 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7466 is an integer, which is important for empty lines. (Bug#9149)
7468 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7470 * frame.c (Fmodify_frame_parameters): In tty case, update the
7471 default face if necessary (Bug#4238).
7473 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7475 * editfns.c (Fstring_to_char): No need to explain what a character
7476 is in the docstring (Bug#6576).
7478 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7480 * xml.c (parse_region): Make sure we always return a tree.
7482 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7484 * xml.c (parse_region): If a document contains only comments,
7487 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7489 * xml.c (make_dom): Return comments, too.
7491 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7494 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7495 and the surrounding thread.
7496 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7497 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7498 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7500 * s/openbsd.h (BROKEN_SIGIO): Define.
7501 * unexelf.c (unexec) [__OpenBSD__]:
7502 Don't update the .mdebug section of the Alpha COFF symbol table.
7504 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7506 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7509 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7511 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7512 This fixes some race conditions on the permissions of any newly
7515 * alloc.c (valid_pointer_p): Use pipe, not open.
7516 This fixes some permissions issues when debugging.
7518 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7519 If fchown fails to set both uid and gid, try to set just gid,
7520 as that is sometimes allowed. Adjust the file's mode to eliminate
7521 setuid or setgid bits that are inappropriate if fchown fails.
7523 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7525 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7526 to compare Lisp_Objects.
7527 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7528 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7529 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7531 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7533 * lread.c (read_integer): Unread even EOF character.
7534 (read1): Likewise. Properly record start position of symbol.
7536 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7537 symbol character follows.
7539 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7541 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7542 This works around a problem with the previous change to Fcopy_file.
7543 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7544 and without this change, GCC might complain about discarding
7545 fchown's return value.
7547 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7549 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7551 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7553 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7555 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7557 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7558 it's used from the C level.
7560 * process.c: Use the same condition for POLL_FOR_INPUT in both
7561 keyboard.c and process.c (bug#1858).
7563 2011-07-09 Lawrence Mitchell <wence@gmx.li>

7566 (Fgnutls_boot): Use it.
7568 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7570 * doc.c (Fsubstitute_command_keys): Revert last change.
7572 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7574 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7575 quotes the next character, and doesn't affect other longer
7576 sequences (bug#8935).
7578 * lread.c (syms_of_lread): Clarify that is isn't only
7579 `eval-buffer' and `eval-defun' that's affected by
7580 `lexical-binding' (bug#8460).
7582 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7584 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7585 bidi redisplay when a line includes both an image and is truncated.
7587 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7589 Fix minor problems found by static checking.
7590 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7591 (elsz): Now a signed constant, not a size_t var. We prefer signed
7592 types to unsigned, to avoid integer comparison confusion. Without
7593 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7594 "cannot optimize loop, the loop counter may overflow", a symptom
7596 * indent.c (Fvertical_motion): Mark locals as initialized.
7597 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7599 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7601 * search.c (Fre_search_backward): Mention `case-fold-search' in
7602 all the re_search_* functions (bug#8138).
7604 * keyboard.c (Fopen_dribble_file): Document when the file is

7619 NULL (avoids a crash in bidi_paragraph_init).
7620 Initialize itb.string.lstring.
7621 (init_iterator): Call bidi_init_it only of a valid
7622 buffer position was specified. Initialize paragraph_embedding to
7624 (reseat_to_string): Initialize the bidi iterator.
7625 (display_string): If we need to ignore text properties of
7626 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7627 original value of -1 will not work with bidi.)
7628 (compute_display_string_pos): First arg is now struct
7629 `text_pos *'; all callers changed. Support display properties on
7631 (compute_display_string_end): Support display properties on Lisp
7633 (init_iterator, reseat_1, reseat_to_string): Initialize the
7634 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7635 when iterating on a string not from display properties).
7636 (compute_display_string_pos, compute_display_string_end):
7637 Fix calculation of the object to scan. Fixes an error when using
7639 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7640 base_level_stop; instead, set base_level_stop to BEGV.
7641 Fixes crashes in vertical-motion.
7642 (next_element_from_buffer): Improve commentary for when
7643 the iterator is before prev_stop.
7644 (init_iterator): Initialize bidi_p from the default value of
7645 bidi-display-reordering, not from buffer-local value. Use the
7646 buffer-local value only if initializing for buffer iteration.
7647 (handle_invisible_prop): Support invisible properties on strings
7648 that are being bidi-reordered.
7649 (set_iterator_to_next): Support bidi reordering of C strings and
7651 (next_element_from_string): Support bidi reordering of Lisp
7653 (handle_stop_backwards): Support Lisp strings as well.
7654 (display_string): Support display of R2L glyph rows.
7655 Use IT_STRING_CHARPOS when displaying from a Lisp string.
7656 (init_iterator): Don't initialize it->bidi_p for strings
7658 (reseat_to_string): Initialize it->bidi_p for strings here.
7659 (next_element_from_string, next_element_from_c_string)
7660 (next_element_from_buffer): Add xassert's for correspondence
7661 between IT's object being iterated and it->bidi_it.string
7663 (face_before_or_after_it_pos): Support bidi iteration.
7664 (next_element_from_c_string): Handle the case of the first string
7665 character that is not the first one in the visual order.
7666 (get_visually_first_element): New function, refactored from common
7667 parts of next_element_from_buffer, next_element_from_string, and
7668 next_element_from_c_string.
7669 (tool_bar_lines_needed, redisplay_tool_bar)
7670 (display_menu_bar): Force left-to-right direction. Add a FIXME
7671 comment for making that be controlled by a user option.
7672 (push_it, pop_it): Save and restore the state of the
7673 bidi iterator. Save and restore the bidi_p flag.
7674 (pop_it): Iterate out of display property for string iteration as
7676 (iterate_out_of_display_property): Support iteration over strings.
7677 (handle_single_display_spec): Set up it->bidi_it for iteration
7678 over a display string, and call bidi_init_it.

7681 iterator for displaying display or overlay strings.
7682 (forward_to_next_line_start): Don't use the shortcut if
7684 (back_to_previous_visible_line_start): If handle_display_prop
7685 pushed the iterator stack, restore the internal state of the bidi
7686 iterator by calling bidi_pop_it same number of times.
7687 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
7688 and we are bidi-iterating, don't decrement the iterator position;
7689 instead, set the first_elt flag in the bidi iterator, to produce
7691 (reseat_1): Remove redundant setting of string_from_display_prop_p.
7692 (push_display_prop): xassert that we are iterating a buffer.
7693 (push_it, pop_it): Save and restore paragraph_embedding member.
7694 (handle_single_display_spec, next_overlay_string)

7696 (push_display_prop): Set up the `unibyte' member of bidi_it.string
7697 correctly. Don't assume unibyte strings are not bidi-reordered.
7698 (compute_display_string_pos)
7699 (compute_display_string_end): Fix handling the case of C string.
7700 (push_it, pop_it): Save and restore from_disp_prop_p.
7701 (handle_single_display_spec, push_display_prop): Set the
7702 from_disp_prop_p flag.
7703 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

7707 for verifying that the iterator position is in sync with the bidi
7709 (handle_single_display_spec, get_overlay_strings_1)
7710 (push_display_prop): Fix initialization of paragraph direction for
7711 string when that of the parent object is not yet determined.

7723 (try_scrolling, redisplay_window, display_line): Use them when
7724 saving a temporary copy of the iterator and restoring it back.
7725 (back_to_previous_visible_line_start, reseat_1)
7726 (init_iterator): Empty the bidi cache "stack".
7727 (move_it_in_display_line_to): If iterator ended up at
7728 EOL, but we never saw any buffer positions smaller than
7729 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
7730 motion in bidi-reordered lines.
7731 (move_it_in_display_line_to): Record prev_method and prev_pos
7732 immediately before the call to set_iterator_to_next. Fixes cursor
7733 motion in bidi-reordered lines with stretch glyphs and strings
7734 displayed in margins. (Bug#8133) (Bug#8867)
7735 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
7737 (pos_visible_p): Support positions in bidi-reordered lines.
7738 Save and restore bidi cache.
7740 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
7741 (bidi_paragraph_info): Delete unused struct.
7742 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
7743 (bidi_cache_start): New variable.

7749 (bidi_level_of_next_char, bidi_find_other_level_edge)
7750 (bidi_move_to_visually_next): Compare cache index with
7751 bidi_cache_start rather than with zero.
7752 (bidi_fetch_char): Accept new argument STRING; all callers
7753 changed. Support iteration over a string. Support strings with
7754 display properties. Support unibyte strings. Fix the type of
7755 `len' according to what STRING_CHAR_AND_LENGTH expects.
7756 (bidi_paragraph_init, bidi_resolve_explicit_1)
7757 (bidi_resolve_explicit, bidi_resolve_weak)

7768 initialized to valid values.
7769 (bidi_init_it): Don't initialize charpos and bytepos with invalid
7771 (bidi_level_of_next_char): Allow the sentinel "position" to pass
7772 the test for valid cached positions. Fix the logic for looking up
7773 the sentinel state in the cache. GCPRO the Lisp string we are
7775 (bidi_push_it, bidi_pop_it): New functions.
7776 (bidi_initialize): Initialize the bidi cache start stack pointer.
7777 (bidi_cache_ensure_space): New function, refactored from part of

7781 (bidi_count_bytes, bidi_char_at_pos): New functions.
7782 (bidi_cache_search): Don't assume bidi_cache_last_idx is
7783 always valid if bidi_cache_idx is valid.

8121 (clone_per_buffer_values): Don't assume that

8163 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8164 subseconds part to the entropy, as that's a bit more random.
8165 Prefer signed to unsigned, since the signedness doesn't matter and
8166 in general we prefer signed. When given a limit, use a
8167 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8168 latter isn't right if USE_2_TAGS_FOR_INTS.
8169 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8170 not 0..VALMASK. Don't discard "excess" bits that random () returns.

8183 This is more efficient than Ffile_directory_p and avoids a minor race.
8185 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8187 * buffer.c (Foverlay_put): Say what the return value is
8190 * fileio.c (barf_or_query_if_file_exists): Check first if the file

8194 error be more correct.
8196 * fns.c (Frequire): Remove the mention of the .gz files, since
8197 that's installation-specific, but keep the mention of

8213 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

8313 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
8315 * eval.c (struct backtrace): Simplify and port the data structure.
8316 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8317 signed bit field, as this assumption is not portable and it makes
8318 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8319 "char debug_on_exit : 1" as this is not portable either; instead,
8320 use the portable "unsigned int debug_on_exit : 1". Remove unused
8321 member evalargs. Remove obsolete comments about cc bombing out.
8323 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8359 and not through other includes.
8361 2011-06-27 Martin Rudalics <rudalics@gmx.at>
8363 * buffer.c (Qclone_number): Declare static and DEFSYM it.
8364 (sort_overlays, overlay_strings): When an overlay's clone number

8395 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
8396 and use min_width/height from frames size_hint to set
8397 min_width/height (Bug#8919).
8399 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
8400 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

8411 * process.c (wait_reading_process_output): Bypass select if
8412 waiting for a cell while ignoring keyboard input, and input is

8485 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
8487 Integer and buffer overflow fixes (Bug#8873).
8489 * print.c (printchar, strout): Check for string overflow.
8490 (PRINTPREPARE, printchar, strout):
8491 Don't set size unless allocation succeeds.
8493 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
8494 for sizes. Check for string overflow more accurately.
8495 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
8497 * macros.c: Integer and buffer overflow fixes.
8498 * keyboard.h (struct keyboard.kbd_macro_bufsize):
8499 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

8505 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
8507 * lread.c: Integer overflow fixes.
8508 (read_integer): Radix is now EMACS_INT, not int,
8509 to improve quality of diagnostics for out-of-range radices.
8510 Calculate buffer size correctly for out-of-range radices.
8511 (read1): Check for integer overflow in radices, and in
8512 read-circle numbers.
8513 (read_escape): Avoid int overflow.
8514 (Fload, openp, read_buffer_size, read1)
8515 (substitute_object_recurse, read_vector, read_list, map_obarray):

8525 Now ptrdiff_t, not int.
8526 (read1): Don't assume doc string length fits in int. Check for
8527 out-of-range doc string lengths.
8528 (read_list): Don't assume file position fits in int.
8529 (read_escape): Check for hex character overflow.
8531 2011-06-22 Leo Liu <sdl.web@gmail.com>
8533 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
8534 Move to minibuffer.el.
8536 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8538 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8539 The following patches are for when GLYPH_DEBUG && !XASSERT.
8540 * dispextern.h (trace_redisplay_p, dump_glyph_string):
8541 * dispnew.c (flush_stdout):
8542 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8543 Mark as externally visible.
8544 * dispnew.c (check_window_matrix_pointers): Now static.
8545 * dispnew.c (window_to_frame_vpos):
8546 * xfns.c (unwind_create_frame):
8547 * xterm.c (x_check_font): Remove unused local.
8548 * scroll.c (CHECK_BOUNDS):
8549 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8550 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8551 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8552 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8553 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8555 (debug_method_add): Use va_list and vsprintf rather than relying
8556 on undefined behavior with wrong number of arguments.
8557 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8558 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8559 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8560 since we're not interested in debugging glyphs with old libraries.
8561 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8562 GCC 4.6.0's static checking.
8564 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8566 Integer overflow and signedness fixes (Bug#8873).
8567 A few related buffer overrun fixes, too.

8575 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
8576 (x_create_bitmap_from_xpm_data):
8577 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
8578 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
8580 * xfaces.c (load_pixmap):
8581 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
8582 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
8583 (.bitmaps_last, struct x_output.icon_bitmap):
8584 Use ptrdiff_t, not int, for bitmap indexes.
8585 (x_allocate_bitmap_record): Check for size overflow.
8586 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
8588 Use ptrdiff_t, not int, for overlay counts.
8589 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
8590 * editfns.c (overlays_around, get_pos_property):
8591 * textprop.c (get_char_property_and_overlay):
8592 * xdisp.c (next_overlay_change, note_mouse_highlight):
8593 * xfaces.c (face_at_buffer_position):
8594 * buffer.c (OVERLAY_COUNT_MAX): New macro.
8595 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8596 (Fnext_overlay_change, Fprevious_overlay_change)
8597 (mouse_face_overlay_overlaps, Foverlays_in):
8598 Use ptrdiff_t, not int, for sizes.
8599 (overlays_at, overlays_in): Check for size-calculation overflow.
8601 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8603 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8604 (x_session_initialize): Do not assume string length fits in int.
8606 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8607 This is unlikely, but can occur if DPI is outlandish.
8609 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8610 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8612 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8613 * xrdb.c (magic_file_p, search_magic_path):
8614 Omit last arg SUFFIX; it was always 0. All callers changed.
8615 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
8617 * xfont.c (xfont_match): Avoid need for strlen.
8619 * xfns.c: Don't assume strlen fits in int.

8622 * xdisp.c (message_log_check_duplicate): Return intmax_t,
8623 not unsigned long, as we prefer signed integers. All callers changed.
8624 Detect integer overflow in repeat count.
8625 (message_dolog): Don't assume print length fits in 39 bytes.
8626 (display_mode_element): Don't assume strlen fits in int.
8628 * termcap.c: Don't assume sizes fit in int and never overflow.
8629 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8630 (gobble_line): Check for size-calculation overflow.
8632 * minibuf.c (Fread_buffer):
8633 * lread.c (intern, intern_c_string):
8634 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8635 Don't assume string length fits in int.
8637 * keyboard.c (parse_tool_bar_item):
8638 * gtkutil.c (style_changed_cb): Avoid need for strlen.
8640 * font.c: Don't assume string length fits in int.

8644 Don't assume integer property fits in fixnum.
8645 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
8647 * filelock.c: Fix some buffer overrun and integer overflow issues.
8648 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8649 Reformulate so as not to need the command string.
8650 Invoke gzip -cd rather than gunzip, as it's more portable.
8651 (lock_info_type, lock_file_1, lock_file):
8652 Don't assume pid_t and time_t fit in unsigned long.
8653 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8654 (current_lock_owner): Prefer signed type for sizes.
8655 Use memcpy, not strncpy, where memcpy is what is really wanted.
8656 Don't assume (via atoi) that time_t and pid_t fit in int.
8657 Check for time_t and/or pid_t out of range, e.g., via a network share.
8658 Don't alloca where an auto var works fine.
8660 * fileio.c: Fix some integer overflow issues.
8661 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8662 Don't assume string length fits in int.
8663 (directory_file_name): Don't assume string length fits in long.
8664 (make_temp_name): Don't assume pid fits in int, or that its print
8665 length is less than 20.
8667 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8669 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8671 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
8673 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
8674 We prefer signed integers, even for size calculations.
8676 * emacs.c: Don't assume string length fits in 'int'.
8677 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
8678 (main): Don't invoke strlen when not needed.
8680 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

8683 * callproc.c (getenv_internal_1, getenv_internal)
8685 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8687 * lread.c (invalid_syntax): Omit length argument.
8688 All uses changed. This doesn't fix a bug, but it simplifies the
8689 code away from its former Hollerith-constant appearance, and it's
8690 one less 'int' to worry about when looking at integer-overflow issues.
8691 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8693 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8694 This didn't break anything, but it didn't help either.
8695 It's confusing to put a bogus integer in a place where the actual
8696 value does not matter.
8697 (LIST_END_P): Remove unused macro and its bogus comment.
8698 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8700 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8701 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8703 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8704 We prefer signed types, and the value cannot exceed the EMACS_INT
8705 range anyway (because otherwise the length would not be representable).
8706 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8707 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8708 This avoids a GCC warning when WIDE_EMACS_INT.
8710 * indent.c (sane_tab_width): New function.
8711 (current_column, scan_for_column, Findent_to, position_indentation)
8712 (compute_motion): Use it. This is just for clarity.
8713 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8715 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8717 * lisp.h (lint_assume): New macro.
8718 * composite.c (composition_gstring_put_cache):
8719 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8721 * editfns.c, insdel.c:
8722 Omit unnecessary forward decls, to simplify future changes.
8724 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8726 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8728 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8729 Use much-faster test for byte-length change.
8730 Don't assume string byte-length fits in 'int'.
8731 Check that character arg fits in 'int'.
8732 (mapcar1): Declare byte as byte, for clarity.
8734 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8736 * fns.c (concat): Catch string overflow earlier.
8737 Do not rely on integer wraparound.
8739 * dispextern.h (struct it.overlay_strings_charpos)
8740 (struct it.selective): Now EMACS_INT, not int.
8741 * xdisp.c (forward_to_next_line_start)
8742 (back_to_previous_visible_line_start)
8743 (reseat_at_next_visible_line_start, next_element_from_buffer):
8744 Don't arbitrarily truncate the value of 'selective' to int.
8746 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8748 * composite.c: Don't truncate sizes to 'int'.
8749 (composition_gstring_p, composition_reseat_it)
8750 (composition_adjust_point): Use EMACS_INT, not int.
8751 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8752 not EMACS_UINT, for indexes.
8754 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8756 * buffer.c: Include <verify.h>.
8757 (struct sortvec.priority, struct sortstr.priority):
8758 Now EMACS_INT, not int.
8759 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8760 (struct sortstr.size, record_overlay_string)
8761 (struct sortstrlist.size, struct sortlist.used):
8762 Don't truncate size to int.
8763 (record_overlay_string): Check for size-calculation overflow.
8764 (init_buffer_once): Check at compile-time, not run-time.
8766 2011-06-22 Jim Meyering <meyering@redhat.com>
8768 Don't leak an XBM-image-sized buffer
8769 * image.c (xbm_load): Free the image buffer after using it.
8771 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
8774 * composite.c (find_automatic_composition): Omit needless 'return 0;'
8775 that Sun C diagnosed.
8776 * fns.c (secure_hash): Fix pointer signedness issue.
8777 * intervals.c (static_offset_intervals): New function.
8778 (offset_intervals): Use it.
8780 2011-06-21 Leo Liu <sdl.web@gmail.com>
8783 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
8786 * fns.c (secure_hash): Rename from crypto_hash_function and change
8787 the first arg to accept symbols.
8788 (Fsecure_hash): New primitive.
8789 (syms_of_fns): New symbols.
8791 2011-06-20 Deniz Dogan <deniz@dogan.se>
8793 * process.c (Fset_process_buffer): Clarify return value in
8796 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
8798 * dispnew.c (add_window_display_history): Use BVAR.
8800 * xdisp.c (debug_method_add): Use BVAR.
8801 (check_window_end, dump_glyph_matrix, dump_glyph)
8802 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
8804 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
8807 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
8808 check till after the cache is created in init_frame_faces.
8810 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
8812 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
8814 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
8816 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8817 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8818 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8820 Improve buffer-overflow checking (Bug#8873).
8821 * fileio.c (Finsert_file_contents):
8822 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8823 Remove the old (too-loose) buffer overflow checks.
8824 They weren't needed, since make_gap checks for buffer overflow.
8825 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8826 The old code merely checked for Emacs fixnum overflow, and relied
8827 on undefined (wraparound) behavior. The new code avoids undefined
8828 behavior, and also checks for ptrdiff_t and/or size_t overflow.
8830 * editfns.c (Finsert_char): Don't dump core with very negative counts.
8831 Tune. Don't use wider integers than needed. Don't use alloca.
8832 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
8834 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8836 * insdel.c, lisp.h (buffer_overflow): New function.
8837 (insert_from_buffer_1, replace_range, replace_range_2):
8838 * insdel.c (make_gap_larger):
8839 * editfns.c (Finsert_char):
8840 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8842 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
8844 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
8846 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
8848 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
8849 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
8851 * fileio.c: Don't assume EMACS_INT fits in off_t.
8852 (emacs_lseek): New static function.
8853 (Finsert_file_contents, Fwrite_region): Use it.
8854 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
8856 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
8858 * fns.c: Don't overflow int when computing a list length.
8859 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
8860 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
8861 truncation on 64-bit hosts. Check for QUIT every
8862 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
8863 faster and is responsive enough.
8864 (Flength): Report an error instead of overflowing an integer.
8865 (Fsafe_length): Return a float if the value is not representable
8866 as a fixnum. This shouldn't happen except in contrived situations.
8867 (Fnthcdr, Fsort): Don't assume list length fits in int.
8868 (Fcopy_sequence): Don't assume vector length fits in int.
8870 * alloc.c: Check that resized vectors' lengths fit in fixnums.
8871 (header_size, word_size): New constants.
8872 (allocate_vectorlike): Don't check size overflow here.
8873 (allocate_vector): Check it here instead, since this is the only
8874 caller of allocate_vectorlike that could cause overflow.
8875 Check that the new vector's length is representable as a fixnum.
8877 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
8878 The previous code was bogus. For example, next_almost_prime (32)
8879 returned 39, which is undesirable as it is a multiple of 3; and
8880 next_almost_prime (24) returned 25, which is a multiple of 5 so
8881 why was the code bothering to check for multiples of 7?
8883 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
8885 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
8887 Variadic C functions now count arguments with ptrdiff_t.
8888 This partly undoes my 2011-03-30 change, which replaced int with size_t.
8889 Back then I didn't know that the Emacs coding style prefers signed int.
8890 Also, in the meantime I found a few more instances where arguments
8891 were being counted with int, which may truncate counts on 64-bit
8892 machines, or EMACS_INT, which may be unnecessarily wide.
8893 * lisp.h (struct Lisp_Subr.function.aMANY)
8894 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
8895 Arg counts are now ptrdiff_t, not size_t.
8896 All variadic functions and their callers changed accordingly.
8897 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
8898 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
8899 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
8900 * callint.c (Fcall_interactively): Check arg count for overflow,
8901 to avoid potential buffer overrun. Use signed char, not 'int',
8902 for 'varies' array, so that we needn't bother to check its size
8903 calculation for overflow.
8904 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
8905 * eval.c (apply_lambda):
8906 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
8907 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
8908 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
8910 * callint.c (Fcall_interactively): Don't use index var as event count.
8912 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
8913 * mem-limits.h (SIZE): Remove; no longer used.
8915 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
8917 Remove unnecessary casts.
8918 * xterm.c (x_term_init):
8919 * xfns.c (x_set_border_pixel):
8920 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
8921 These aren't needed now that we assume ANSI C.
8923 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
8924 It's more likely to cause problems (due to unsigned overflow)
8927 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
8929 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
8931 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
8933 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
8935 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
8937 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
8939 GLYPH_CODE_FACE returns EMACS_INT, not int.
8940 * dispextern.h (merge_faces):
8941 * xfaces.c (merge_faces):
8942 * xdisp.c (get_next_display_element, next_element_from_display_vector):
8943 Don't assume EMACS_INT fits in int.
8945 * character.h (CHAR_VALID_P): Remove unused parameter.
8946 * fontset.c, lisp.h, xdisp.c: All uses changed.
8948 * editfns.c (Ftranslate_region_internal): Omit redundant test.
8950 * fns.c (concat): Minor tuning based on overflow analysis.
8951 This doesn't fix any bugs. Use int to hold character, instead
8952 of constantly refetching from Emacs object. Use XFASTINT, not
8953 XINT, for value known to be a character. Don't bother comparing
8954 a single byte to 0400, as it's always less.
8956 * floatfns.c (Fexpt):
8957 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
8959 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
8962 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
8964 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
8965 Without this fix, on a 64-bit host (aset S 0 4294967386) would
8966 incorrectly succeed when S was a string, because 4294967386 was
8967 truncated before it was used.
8969 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
8970 Otherwise, an out-of-range integer could cause undefined behavior
8973 * composite.c: Use int, not EMACS_INT, for characters.
8974 (fill_gstring_body, composition_compute_stop_pos): Use int, not
8975 EMACS_INT, for values that are known to be in character range.
8976 This doesn't fix any bugs but is the usual style inside Emacs and
8977 may generate better code on 32-bit machines.
8979 Make sure a 64-bit char is never passed to ENCODE_CHAR.
8980 This is for reasons similar to the recent CHAR_STRING fix.
8981 * charset.c (Fencode_char): Check that character arg is actually
8982 a character. Pass an int to ENCODE_CHAR.
8983 * charset.h (ENCODE_CHAR): Verify that the character argument is no
8984 wider than 'int', as a compile-time check to prevent future regressions
8987 * character.c (char_string): Remove unnecessary casts.
8989 Make sure a 64-bit char is never passed to CHAR_STRING.
8990 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
8991 by silently ignoring the top 32 bits, allowing some values
8992 that were far too large to be valid characters.
8993 * character.h: Include <verify.h>.
8994 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
8995 arguments are no wider than unsigned, as a compile-time check
8996 to prevent future regressions in this area.
8998 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
8999 (Fsubst_char_in_region):
9001 * xdisp.c (decode_mode_spec_coding):
9002 Adjust to CHAR_STRING's new requirement.
9003 * editfns.c (Finsert_char, Fsubst_char_in_region):
9004 * fns.c (concat): Check that character args are actually
9005 characters. Without this test, these functions did the wrong
9006 thing with wildly out-of-range values on 64-bit hosts.
9008 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9009 These casts should not be needed on 32-bit hosts, either.
9010 * keyboard.c (read_char):
9011 * lread.c (Fload): Remove casts to unsigned.
9013 * lisp.h (UNSIGNED_CMP): New macro.
9014 This fixes comparison bugs on 64-bit hosts.
9015 (ASCII_CHAR_P): Use it.
9016 * casefiddle.c (casify_object):
9017 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9018 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9019 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9020 * dispextern.h (FACE_FROM_ID):
9021 * keyboard.c (read_char): Use UNSIGNED_CMP.
9023 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9024 not to EMACS_INT, to avoid GCC warning.
9026 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9028 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9029 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9030 isn't needed on 32-bit machines.
9032 * buffer.c (Fgenerate_new_buffer_name):
9033 Use EMACS_INT for count, not int.
9034 (advance_to_char_boundary): Return EMACS_INT, not int.
9036 * data.c (Qcompiled_function): Now static.
9038 * window.c (window_body_lines): Now static.
9040 * image.c (gif_load): Rename local to avoid shadowing.
9042 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9043 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9044 * alloc.c (make_save_value): Integer argument is now of type
9046 (mark_object): Use ptrdiff_t, not int.
9047 * lisp.h (pD): New macro.
9048 * print.c (print_object): Use it.
9050 * alloc.c: Use EMACS_INT, not int, to count objects.
9051 (total_conses, total_markers, total_symbols, total_vector_size)
9052 (total_free_conses, total_free_markers, total_free_symbols)
9053 (total_free_floats, total_floats, total_free_intervals)
9054 (total_intervals, total_strings, total_free_strings):
9055 Now EMACS_INT, not int. All uses changed.
9056 (Fgarbage_collect): Compute overall total using a double, so that
9057 integer overflow is less likely to be a problem. Check for overflow
9058 when converting back to an integer.
9059 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9060 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9061 These were 'int' variables that could overflow on 64-bit hosts;
9062 they were never used, so remove them instead of repairing them.
9063 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9064 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9065 Previously, this ceilinged at INT_MAX, but that doesn't work on
9067 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9069 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9070 (allocate_vectorlike): Check for ptrdiff_t overflow.
9071 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9072 when a (possibly-narrower) signed value would do just as well.
9073 We prefer using signed arithmetic, to avoid comparison confusion.
9075 * alloc.c: Catch some string size overflows that we were missing.
9076 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9077 for convenience in STRING_BYTES_MAX.
9078 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9079 The definition here is exact; the one in lisp.h was approximate.
9080 (allocate_string_data): Check for string overflow. This catches
9081 some instances we weren't catching before. Also, it catches
9082 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9083 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9084 and ptrdiff_t and EMACS_INT are both 64 bits.
9086 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9087 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9088 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9090 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9092 * alloc.c (Fmake_string): Check for out-of-range init.
9094 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9096 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9098 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
9100 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
9101 xg_get_default_scrollbar_width.
9103 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
9104 (int_gtk_range_get_value): Move to the scroll bar part of the file.
9105 (style_changed_cb): Call update_theme_scrollbar_width and call
9106 x_set_scroll_bar_default_width and xg_frame_set_char_size for
9107 all frames (Bug#8505).
9108 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
9109 Call gtk_window_set_resizable if HAVE_GTK3.
9110 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9111 and height if HAVE_GTK3 (Bug#8505).
9112 (scroll_bar_width_for_theme): New variable.
9113 (update_theme_scrollbar_width): New function.
9114 (xg_get_default_scrollbar_width): Move code to
9115 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
9116 (xg_initialize): Call update_theme_scrollbar_width.
9118 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
9120 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
9122 2011-06-12 Martin Rudalics <rudalics@gmx.at>
9124 * frame.c (make_frame): Call other_buffer_safely instead of
9127 * window.c (temp_output_buffer_show): Call display_buffer with
9128 second argument Vtemp_buffer_show_specifiers and reset latter
9129 immediately after the call.
9130 (Vtemp_buffer_show_specifiers): New variable.
9131 (auto_window_vscroll_p, next_screen_context_lines)
9132 (Vscroll_preserve_screen_position): Remove leading asterisks from
9135 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
9137 Fix minor problems found by GCC 4.6.0 static checking.
9138 * buffer.c (Qclone_number): Remove for now, as it's unused.
9139 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
9140 (record_buffer): Remove unused local.
9141 * frame.c (other_visible_frames, frame_buffer_list): Now static.
9142 (set_frame_buffer_list): Remove; unused.
9143 * frame.h (other_visible_frames): Remove decl.
9144 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
9145 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
9146 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
9148 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
9149 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
9150 Define only if HAVE_GPM.
9151 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
9152 (update_hints_inhibit): Remove; never set. All uses removed.
9153 * widgetprv.h (emacsFrameClassRec): Remove decl.
9154 * window.c (delete_deletable_window): Now returns void, since it
9155 wasn't returning anything.
9156 (compare_window_configurations): Remove unused locals.
9157 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
9158 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
9159 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
9160 the same widths as pointers. This follows up on the 2011-05-06 patch.
9161 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
9162 * xterm.h: Likewise.
9163 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
9165 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
9167 * makefile.w32-in: Update dependencies.
9168 (LISP_H): Add lib/intprops.h.
9170 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
9172 * image.c (gif_load): Add animation frame delay to the metadata.
9173 (syms_of_image): Use DEFSYM. New symbol `delay'.

9653 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9654 (bidi_level_of_next_char, bidi_move_to_visually_next):
9655 Support character positions inside a run of characters covered by a
9657 (bidi_paragraph_init, bidi_resolve_explicit_1)
9658 (bidi_level_of_next_char): Call bidi_fetch_char and
9659 bidi_fetch_char_advance instead of FETCH_CHAR and
9661 (bidi_init_it): Initialize new members.
9662 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
9664 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
9665 instead of using explicit *_CHAR codes.
9666 (bidi_resolve_explicit, bidi_resolve_weak):
9667 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
9668 bidirectional text is supported only in multibyte buffers.
9669 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
9670 it to initialize the frame_window_p member of struct bidi_it.
9671 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
9672 (bidi_resolve_explicit, bidi_resolve_weak)
9673 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
9674 bidi_it->nchars is non-positive.
9675 (bidi_level_of_next_char): Don't try to lookup the cache for the
9676 next/previous character if nothing is cached there yet, or if we
9677 were just reseat()'ed to a new position.
9679 * xdisp.c (set_cursor_from_row): Set start and stop points
9680 according to the row's direction when priming the loop that looks
9681 for the glyph on which to display cursor.
9682 (single_display_spec_intangible_p): Function deleted.
9683 (display_prop_intangible_p): Reimplement to call
9684 handle_display_spec instead of single_display_spec_intangible_p.
9685 Accept 3 additional arguments needed by handle_display_spec.
9686 This fixes incorrect cursor motion across display property with complex
9687 values: lists, `(when COND...)' forms, etc.
9688 (single_display_spec_string_p): Support property values that are
9689 lists with the argument STRING its top-level element.
9690 (display_prop_string_p): Fix the condition for processing a
9691 property that is a list to be consistent with handle_display_spec.
9692 (handle_display_spec): New function, refactored from the
9693 last portion of handle_display_prop.
9694 (compute_display_string_pos): Accept additional argument
9695 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
9696 value of a `display' property is a "replacing spec".
9697 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
9698 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
9699 the display property, but just return a value indicating whether
9700 the display property will replace the characters it covers.
9701 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
9702 frame_window_p members of struct bidi_it.
9703 (compute_display_string_pos, compute_display_string_end):
9705 (push_it): Accept second argument POSITION, where pop_it should
9706 jump to continue iteration.
9707 (reseat_1): Initialize bidi_it.disp_pos.
9709 * keyboard.c (adjust_point_for_property): Adjust the call to
9710 display_prop_intangible_p to its new signature.
9712 * dispextern.h (struct bidi_it): New member frame_window_p.
9713 (bidi_init_it): Update prototypes.
9714 (display_prop_intangible_p): Update prototype.
9715 (compute_display_string_pos, compute_display_string_end):
9717 (struct bidi_it): New members nchars and disp_pos. ch_len is now
9720 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
9722 Malloc failure behavior now depends on size of allocation.
9723 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
9724 * lisp.h: Change signatures accordingly.
9725 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
9726 All callers changed. (Bug#8762)
9728 * gnutls.c: Use Emacs's memory allocators.
9729 Without this change, the gnutls library would invoke malloc etc.
9730 directly, which causes problems on non-SYNC_INPUT hosts, and which
9731 runs afoul of improving memory_full behavior. (Bug#8761)
9732 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9733 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9734 xfree instead of the default malloc, realloc, free.
9735 (Fgnutls_boot): No need to check for memory allocation failure,
9736 since xmalloc does that for us.
9738 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
9739 * category.c (hash_get_category_set):
9740 * ccl.c (ccl_driver):
9741 * charset.c (Fdefine_charset_internal):

9752 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
9753 (Fsxhash, Fgethash, Fputhash, Fmaphash):
9754 * image.c (make_image, search_image_cache, lookup_image)
9755 (xpm_put_color_table_h):
9756 * lisp.h (struct Lisp_Hash_Table):
9757 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
9758 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
9759 for hashes and hash indexes, instead of 'unsigned' and 'int'.
9760 * alloc.c (allocate_vectorlike):
9761 Check for overflow in vector size calculations.
9762 * ccl.c (ccl_driver):
9763 Check for overflow when converting EMACS_INT to int.
9764 * fns.c, image.c: Remove unnecessary static decls that would otherwise
9765 need to be updated by these changes.
9766 * fns.c (make_hash_table, maybe_resize_hash_table):
9767 Check for integer overflow with large hash tables.
9768 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9769 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9770 (SXHASH_REDUCE): New macro.
9771 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
9772 Use it instead of discarding useful hash info with large hash values.
9773 (sxhash_float): New function.
9774 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
9775 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
9776 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9777 Rewrite to use FIXNUM_BITS, as this simplifies things.
9778 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9779 Adjust signatures to match updated version of code.
9780 (consing_since_gc): Now EMACS_INT, since a single hash table can
9781 use more than INT_MAX bytes.
9783 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
9785 Make it possible to build with GCC-4.6+ -O2 -flto.
9787 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
9789 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
9791 * minibuf.c (get_minibuffer, read_minibuf_unwind):
9792 Call minibuffer-inactive-mode.
9794 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
9796 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
9797 Update dependencies.
9799 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9801 * data.c (init_data): Remove code for UTS, this system is not
9804 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9806 Don't force ./temacs to start in terminal mode.
9808 * frame.c (make_initial_frame): Initialize faces in all cases, not
9809 only when CANNOT_DUMP is defined.
9810 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
9812 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9814 * dispnew.c (add_window_display_history): Use const for the string
9815 pointer. Remove declaration, not needed.
9817 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9819 Use 'inline', not 'INLINE'.
9820 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
9821 * alloc.c, fontset.c (INLINE): Remove.
9822 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
9823 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
9824 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
9825 * gmalloc.c (register_heapinfo): Use inline unconditionally.
9826 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
9828 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9830 Make it possible to run ./temacs.
9832 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
9833 syms_of_callproc does the same thing. Remove test for
9834 "initialized", do it in the caller.
9835 * emacs.c (main): Avoid calling set_initial_environment when dumping.
9837 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
9839 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
9840 (read_minibuf): Use get_minibuffer.
9841 (syms_of_minibuf): Use DEFSYM.
9842 (Qmetadata): New var.
9843 * data.c (Qbuffer): Don't make it static.
9844 (syms_of_data): Use DEFSYM.
9846 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9848 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
9849 (CCL_CODE_MIN): New macro.
9851 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
9853 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
9855 * eval.c (Qdebug): Now static.
9856 * lisp.h (Qdebug): Remove decl. This reverts a part of the
9857 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
9858 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
9860 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9862 * image.c: Various fixes to ImageMagick code comments.
9863 (Fimagemagick_types): Doc fix.
9865 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
9867 Minor fixes prompted by GCC 4.6.0 warnings.
9869 * xselect.c (converted_selections, conversion_fail_tag): Now static.
9871 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
9872 (x_clipboard_manager_save_all): Move extern decl to ...
9873 * xterm.h: ... here, so that it can be checked for consistency.
9875 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9877 * xselect.c (x_clipboard_manager_save_frame)
9878 (x_clipboard_manager_save_all): New functions.
9879 (Fx_clipboard_manager_save): Lisp function deleted.
9881 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
9882 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
9884 * xterm.h: Update prototype.
9886 2011-05-28 William Xu <william.xwl@gmail.com>
9888 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
9891 2011-05-28 Jim Meyering <meyering@redhat.com>
9893 Avoid a sign-extension bug in crypto_hash_function.
9894 * fns.c (to_uchar): Define.
9895 (crypto_hash_function): Use it to convert some newly-signed
9896 variables to unsigned, to avoid sign-extension bugs. For example,
9897 without this change, (md5 "truc") would evaluate to
9898 45723a2aff78ff4fff7fff1114760e62 rather than the expected
9899 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
9900 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
9902 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9904 Integer overflow fixes.
9906 * dbusbind.c: Serial number integer overflow fixes.
9907 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
9908 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
9909 to hold a serial number that is too large for a fixnum.
9910 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9911 Check for serial numbers out of range. Decode any serial number
9912 that was so large that it became a float. (Bug#8722)
9914 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
9915 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9916 Use XFASTINT rather than XUINT when numbers are nonnegative.
9917 (xd_append_arg, Fdbus_method_return_internal):
9918 (Fdbus_method_error_internal): Likewise. Also, for unsigned
9919 arguments, check that Lisp number is nonnegative, rather than
9920 silently wrapping negative numbers around. (Bug#8722)
9921 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
9924 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
9926 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
9928 ccl: Add integer overflow checks.
9929 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
9930 (IN_INT_RANGE): New macros.
9931 (ccl_driver): Use them to check for integer overflow when
9932 decoding a CCL program. Many of the new checks are whether XINT (x)
9933 fits in int; it doesn't always, on 64-bit hosts. The new version
9934 doesn't catch all possible integer overflows, but it's an
9935 improvement. (Bug#8719)
9937 * alloc.c (make_event_array): Use XINT, not XUINT.
9938 There's no need for unsigned here.
9940 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
9941 This follows up to the 2011-05-06 change that substituted uintptr_t
9942 for EMACS_INT. This case wasn't caught back then.
9944 Rework Fformat to avoid integer overflow issues.
9945 * editfns.c: Include <float.h> unconditionally, as it's everywhere
9946 now (part of C89). Include <verify.h>.
9947 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
9948 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
9949 (Fformat): Avoid the prepass trying to compute sizes; it was only
9950 approximate and thus did not catch overflow reliably. Instead, walk
9951 through the format just once, formatting and computing sizes as we go,
9952 checking for integer overflow at every step, and allocating a larger
9953 buffer as needed. Keep track separately whether the format is
9954 multibyte. Keep only the most-recently calculated precision, rather
9955 than them all. Record whether each argument has been converted to
9956 string. Use EMACS_INT, not int, for byte and char and arg counts.
9957 Support field widths and precisions larger than INT_MAX. Avoid
9958 sprintf's undefined behavior with conversion specifications such as %#d
9959 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
9960 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
9961 formatting out-of-range floating point numbers with int
9964 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
9966 * data.c: Avoid integer truncation in expressions involving floats.
9967 * data.c: Include <intprops.h>.
9968 (arith_driver): When there's an integer overflow in an expression
9969 involving floating point, convert the integers to floating point
9970 so that the resulting value does not suffer from catastrophic
9971 integer truncation. For example, on a 64-bit host (* 4
9972 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
9973 Do not rely on undefined behavior after integer overflow.
9975 merge count_size_as_multibyte, parse_str_to_multibyte
9976 * character.c, character.h (count_size_as_multibyte):
9977 Rename from parse_str_to_multibyte; all uses changed.
9978 Check for integer overflow.
9979 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
9980 since it's now a duplicate of the other. This is more of
9981 a character than a buffer op, so better that it's in character.c.
9982 * fns.c, print.c: Adjust to above changes.
9984 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
9986 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
9988 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9990 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9991 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
9992 (x_clipboard_manager_save): Now static.
9993 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
9995 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9996 (crypto_hash_function): Now static.
9997 Fix pointer signedness problems. Avoid unnecessary initializations.
9999 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10001 * termhooks.h (Vselection_alist): Make it terminal-local.
10003 * terminal.c (create_terminal): Initialize it.

10014 (some_frame_on_display): Delete unused function.
10015 (Fx_own_selection_internal, Fx_get_selection_internal)
10016 (Fx_disown_selection_internal, Fx_selection_owner_p)
10017 (Fx_selection_exists_p): New optional frame arg.
10018 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10019 (x_handle_selection_clear): Don't treat other terminals with the
10020 same keyboard specially. Use the terminal-local Vselection_alist.
10021 (x_clear_frame_selections): Use Frun_hook_with_args.
10023 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10025 * xterm.h: Add support for those atoms.
10027 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10029 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10030 (converted_selections, conversion_fail_tag): New global variables.
10031 (x_selection_request_lisp_error): Free the above.
10032 (x_get_local_selection): Remove unnecessary code.
10033 (x_reply_selection_request): Args changed; handle arbitrary array
10034 of converted selections stored in converted_selections.
10035 Separate the XChangeProperty and SelectionNotify steps.
10036 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10037 (x_convert_selection): New function.
10038 (x_handle_selection_event): Simplify.
10039 (x_get_foreign_selection): Don't ignore incoming requests while
10040 waiting for an answer; this will fail when we implement
10041 SAVE_TARGETS, and seems unnecessary anyway.
10042 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10043 (Vx_sent_selection_functions): Doc fix.
10045 2011-05-26 Leo Liu <sdl.web@gmail.com>
10047 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10049 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10051 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10053 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10054 for fringe update if it has periodic bitmap.
10055 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10056 and fringe_bitmap_periodic_p.
10058 * fringe.c (get_fringe_bitmap_data): New function.
10059 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10060 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10061 row. Mark glyph row for fringe update if periodicity changed.
10063 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10064 for fringe update unless it has periodic bitmap.
10066 2011-05-25 Kenichi Handa <handa@m17n.org>
10068 * xdisp.c (get_next_display_element): Set correct it->face_id for
10069 a static composition.

10083 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10084 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10085 Remove macros that are defined and never used.
10086 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10088 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10090 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10091 (Fx_get_selection_internal): Minor cleanup.
10092 (Fx_own_selection_internal): Rename arguments for consistency with
10095 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10097 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10099 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10101 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10103 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10105 * dispnew.c (scrolling_window): Don't exclude the case that the
10106 last enabled row in the desired matrix touches the bottom boundary.
10108 2011-05-21 Glenn Morris <rgm@gnu.org>
10110 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10111 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10112 and add some more files.
10114 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10116 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10117 report_file_error introduced by the change from 2011-05-07.
10119 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10121 * systime.h (Time): Define only if emacs is defined.
10122 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10123 where the include path doesn't have X11/X.h by default. See
10124 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10126 2011-05-20 Kenichi Handa <handa@m17n.org>
10128 * composite.c (find_automatic_composition): Fix previous change.
10130 2011-05-20 Glenn Morris <rgm@gnu.org>
10132 * lisp.mk: New file, split from Makefile.in.
10133 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10134 (shortlisp): Remove.
10135 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10137 2011-05-19 Glenn Morris <rgm@gnu.org>
10139 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10140 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10141 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10142 (lisp): Set the order to that of loadup.el.
10143 (shortlisp): Make it a copy of $lisp.
10144 (SOME_MACHINE_LISP): Remove.
10145 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10146 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10148 2011-05-18 Kenichi Handa <handa@m17n.org>
10150 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10151 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10152 (find_automatic_composition): Mostly rewrite for efficiency.
10154 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10156 * makefile.w32-in: Update dependencies.
10158 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10160 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10161 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10163 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10165 Fix some integer overflow issues, such as string length overflow.
10167 * insdel.c (count_size_as_multibyte): Check for string overflow.
10169 * character.c (lisp_string_width): Check for string overflow.
10170 Use EMACS_INT, not int, for string indexes and lengths; in
10171 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10172 the resulting string length overflows an EMACS_INT; instead,
10173 report a string overflow if no precision given. When checking for
10174 precision exhaustion, use a check that cannot possibly have
10175 integer overflow. (Bug#8675)
10176 * character.h (lisp_string_width): Adjust to new signature.
10178 * alloc.c (string_overflow): New function.
10179 (Fmake_string): Use it. This doesn't change behavior, but saves
10180 a few bytes and will simplify future changes.
10181 * character.c (string_escape_byte8): Likewise.
10182 * lisp.h (string_overflow): New decl.
10184 Fixups, following up to the user-interface timestamp change.
10185 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10186 for UI timestamps, instead of unsigned long.
10187 * msdos.c (mouse_get_pos): Likewise.
10188 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10189 * w32gui.h (Time): Define by including "systime.h" rather than by
10190 declaring it ourselves. (Bug#8664)
10192 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10193 * image.c (clear_image_cache): Likewise.
10195 * term.c (term_mouse_position): Don't assume time_t wraparound.
10197 Be more systematic about user-interface timestamps.
10198 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10199 and sometimes 'EMACS_UINT', to represent these timestamps.
10200 This change causes it to use 'Time' uniformly, as that's what X uses.
10201 This makes the code easier to follow, and makes it easier to catch
10202 integer overflow bugs such as Bug#8664.
10203 * frame.c (Fmouse_position, Fmouse_pixel_position):
10204 Use Time, not unsigned long, for user-interface timestamps.
10205 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10206 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10207 * keyboard.h (last_event_timestamp): Likewise.
10208 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10209 * menu.h (xmenu_show): Likewise.
10210 * term.c (term_mouse_position): Likewise.
10211 * termhooks.h (struct input_event.timestamp): Likewise.
10212 (struct terminal.mouse_position_hook): Likewise.
10213 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10214 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10215 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10216 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10217 what it was before.
10218 * menu.h, termhooks.h: Include "systime.h", for Time.
10220 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10221 Don't assume that the difference between two unsigned long values
10222 can fit into an integer. At this point, we know button_down_time
10223 <= event->timestamp, so the difference must be nonnegative, so
10224 there's no need to cast the result if double-click-time is
10225 nonnegative, as it should be; check that it's nonnegative, just in
10226 case. This bug is triggered when events are more than 2**31 ms
10227 apart (about 25 days). (Bug#8664)
10229 * xselect.c (last_event_timestamp): Remove duplicate decl.
10230 (x_own_selection): Remove needless cast to unsigned long.
10232 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10233 that always fit in int. Use a sentinel instead of a counter, to
10234 avoid a temp and to allay GCC's concerns about possible int overflow.
10235 * frame.h (struct frame): Use int for menu_bar_items_used
10236 instead of EMACS_INT, since it always fits in int.
10238 * menu.c (grow_menu_items): Check for int overflow.
10240 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10242 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10243 Before, the code was not consistent. These values cannot exceed
10244 2**31 - 1 so there's no need to make them unsigned.
10245 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10246 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10247 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10249 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10251 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10252 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10253 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10254 presumably because the widths might not match.
10256 * window.c (size_window): Avoid needless test at loop start.
10258 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10260 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10262 2011-05-12 Drew Adams <drew.adams@oracle.com>
10264 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10266 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10268 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10269 `width' to `bar_area_x' and `bar_area_width', respectively.
10270 (x_scroll_run): Take account of fringe background extension.
10272 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10273 Rename local vars `left' and `width' to `bar_area_x' and
10274 `bar_area_width', respectively.
10275 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10276 background extension.
10278 2011-05-10 Jim Meyering <meyering@redhat.com>
10280 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10282 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10284 * image.c (Finit_image_library): Return t for built-in image types,
10285 like pbm and xbm. (Bug#8640)
10287 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10289 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10291 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10293 * w32console.c (Fset_screen_color): Doc fix.
10294 (Fget_screen_color): New function.
10295 (syms_of_ntterm): Defsubr it.
10297 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10298 unlink the temporary file if Fcall_process didn't create it in the
10300 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10301 child process will be redirected to a file specified with `:file'.
10302 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10303 cue to call_process_cleanup not to close that handle.
10305 2011-05-07 Ben Key <bkey76@gmail.com>
10307 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10308 one of two shell specific rules, either bootstrap-temacs-CMD or
10309 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10310 to the previous implementation of the bootstrap-temacs rule.
10311 The bootstrap-temacs-CMD rule is similar to the previous
10312 implementation of the bootstrap-temacs rule except that it
10313 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10316 These changes, along with some changes to nt/configure.bat,
10317 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10318 earlier fix to add support for --cflags and --ldflags options
10319 that include quotes so that it works whether make uses cmd or
10322 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10324 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10325 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10327 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10328 a string. Handle both cases.
10329 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10330 (Fdbus_register_method): Use Qinvalid_function.
10332 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10334 * makefile.w32-in: Update dependencies.
10335 (LISP_H): Add inttypes.h and stdin.h.
10336 (PROCESS_H): Add unistd.h.
10338 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10340 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10341 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10343 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10345 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10347 * term.c (vfatal): Remove stray call to va_end.
10348 It's not needed and the C Standard doesn't allow it here anyway.
10350 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10351 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10353 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10356 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10358 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10360 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10362 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10364 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10366 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10367 * charset.c (Fdefine_charset_internal): Don't initialize
10368 charset.code_space[15]. The value was garbage, on hosts with
10369 32-bit int (Bug#8600).
10371 * lread.c (read_integer): Be more consistent with string-to-number.
10372 Use string_to_number to do the actual conversion; this avoids
10373 rounding errors and fixes some other screwups. Without this fix,
10374 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10375 (digit_to_number): Move earlier, for benefit of read_integer.
10376 Return -1 if the digit is out of range for the base, -2 if it is
10377 not a digit in any supported base. (Bug#8602)
10379 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10381 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10382 to match comment at start of function. This also removes a
10383 GCC warning about overflow in a 32+64-bit port.
10385 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10387 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10388 Reported by Stefan Monnier in
10389 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10390 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10391 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10393 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10394 (EMACS_UINTPTR): Likewise, with uintptr_t.
10396 * lisp.h: Prefer 64-bit EMACS_INT if available.
10397 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10398 on 32-bit hosts that have 64-bit int, so that they can access
10400 However, temporarily disable this change unless the temporary
10401 symbol WIDE_EMACS_INT is defined.
10403 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10405 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10406 This removes an assumption that EMACS_INT and long are the same
10407 width as pointers. The assumption is true for Emacs porting targets
10408 now, but we want to make other targets possible.
10409 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10410 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10411 In the rest of the code, change types of integers that hold casted
10412 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10413 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10414 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10415 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10416 No need to cast type when ORing.
10417 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10418 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10419 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10420 assume EMACS_INT is the same width as char *.
10421 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10422 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10423 Remove no-longer-needed casts.
10424 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10425 (xg_tool_bar_help_callback, xg_make_tool_item):
10426 Use EMACS_INTPTR to hold an integer
10427 that will be cast to void *; this can avoid a GCC warning
10428 if EMACS_INT is not the same width as void *.
10429 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10430 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10431 (current_message_1, set_message_1):
10432 Use a local to convert to proper width without a cast.
10433 * xmenu.c (dialog_selection_callback): Likewise.
10435 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10436 Also, don't assume VALBITS / RAND_BITS is less than 5,
10437 and don't rely on undefined behavior when shifting a 1 left into
10439 * lisp.h (get_random): Change signature to match.
10441 * lread.c (hash_string): Use size_t, not int, for hash computation.
10442 Normally we prefer signed values; but hashing is special, because
10443 it's better to use unsigned division on hash table sizes so that
10444 the remainder is nonnegative. Also, size_t is the natural width
10445 for hashing into memory. The previous code used 'int', which doesn't
10446 retain enough info to hash well into very large tables.
10447 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10449 * dbusbind.c: Don't possibly lose pointer info when converting.
10450 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10451 Use XPNTR rather than XHASH, so that the high-order bits of
10452 the pointer aren't lost when converting through void *.
10454 * eval.c (Fautoload): Don't double-shift a pointer.
10456 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10458 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10460 * gnutls.c (DEF_GNUTLS_FN):
10461 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10463 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10465 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10468 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10470 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
10471 New version that can reserve upto 2GB of heap space.
10473 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
10475 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
10477 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
10479 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
10480 `gnutls_certificate_set_x509_key_file'.
10482 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
10484 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
10485 Update dependencies.
10487 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10489 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
10490 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10491 Remove unused parameter `fildes'.
10492 * process.c (read_process_output, send_process): Don't pass it.
10494 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10496 Fix previous change: the library cache is defined in w32.c.
10497 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10498 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
10500 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10502 Implement dynamic loading of GnuTLS on Windows.
10504 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
10505 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
10506 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10509 * gnutls.c (Qgnutls_dll): Define.
10510 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
10511 (gnutls_*): Declare function pointers.
10512 (init_gnutls_functions): New function to initialize function pointers.
10513 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
10514 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
10515 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10516 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
10517 (emacs_gnutls_write, emacs_gnutls_read)
10518 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)

10536 Initialize and staticpro them.
10537 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
10539 * process.c: Include lisp.h before w32.h, not after.
10540 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10541 instead of gnutls_record_check_pending.
10543 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10545 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10547 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

10590 2011-04-30 Eli Zaretskii <eliz@gnu.org>
10592 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10593 rather than `XVECTOR (FOO)->size'.
10595 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10596 inttypes.h, as a gnulib replacement is used if it not available in
10599 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10601 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10602 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10603 of MOST_POSITIVE_FIXNUM. (Bug#8528)

10609 space for up to 2 characters produced in a loop.
10610 (decode_coding_iso_2022): Abort if there isn't enough place in
10611 charbuf for the composition carryover bytes.
10613 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10615 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
10616 aborting when %lld or %lll format is passed.
10617 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
10618 %llo or %llx format is passed. (Bug#8545)
10620 * window.c (window_scroll_line_based): Use a marker instead of
10621 simple variables to record original value of point. (Bug#7952)
10623 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10624 produced by %s or %c overflows available buffer space. (Bug#8545)
10626 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10628 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10629 (SIZE_MAX): Move defn after all includes, as they might #define it.
10631 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10633 * w32.c (init_environment): Warn about defaulting HOME to C:\.
10635 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10637 * keyboard.c (Qdelayed_warnings_hook): Define.
10638 (command_loop_1): Run `delayed-warnings-hook'
10639 if Vdelayed_warnings_list is non-nil.
10640 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
10641 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10643 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10645 * doprnt.c (doprnt): Don't return value smaller than the buffer
10646 size if the message was truncated. (Bug#8545).
10648 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10650 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
10651 (Fx_window_property): #if-0 the whole functions, not just the bodies.
10653 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10655 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
10657 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
10659 * makefile.w32-in: Update dependencies.
10661 2011-04-27 Eli Zaretskii <eliz@gnu.org>
10663 Improve `doprnt' and its usage. (Bug#8545)
10664 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10665 `format_end'. Remove support for %l as a conversion specifier.
10666 Don't use xrealloc. Improve diagnostics when the %l size modifier
10667 is used. Update the commentary.
10669 * eval.c (verror): Simplify calculation of size_t.
10671 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10674 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10676 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10679 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10681 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10682 This makes this file independent of the recent pseudovector change.
10684 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10686 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10688 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10689 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10690 Remove unused local.
10691 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10693 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10694 GCC 4.6.0 optimizes based on type-based alias analysis.
10695 For example, if b is of type struct buffer * and v of type struct
10696 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10697 != &v->size, and therefore "v->size = 1; b->size = 2; return
10698 v->size;" must therefore return 1. This assumption is incorrect
10699 for Emacs, since it type-puns struct Lisp_Vector * with many other
10700 types. To fix this problem, this patch adds a new type struct
10701 vectorlike_header that documents the constraints on layout of vectors
10702 and pseudovectors, and helps optimizing compilers not get fooled
10703 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10704 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10705 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10707 (XSETPVECTYPE): Rewrite in terms of new macro.
10708 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10709 This is a bit clearer, and further avoids the possibility of
10710 undesirable aliasing.
10711 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10712 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10713 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10714 since Lisp_Subr is a special case (no "next" field).
10715 (ASIZE): Now uses header.size rather than size.
10716 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10717 to avoid the hassle of writing XVECTOR (foo)->header.size.
10718 (struct vectorlike_header): New type.
10719 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10720 object, to help avoid aliasing.
10721 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10722 (SUBRP): Likewise, since Lisp_Subr is a special case.
10723 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10724 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10725 (struct Lisp_Hash_Table): Combine first two members into a single
10726 struct vectorlike_header member. All uses of "size" and "next" members
10727 changed to be "header.size" and "header.next".
10728 * buffer.h (struct buffer): Likewise.
10729 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10730 * frame.h (struct frame): Likewise.
10731 * process.h (struct Lisp_Process): Likewise.
10732 * termhooks.h (struct terminal): Likewise.
10733 * window.c (struct save_window_data, struct saved_window): Likewise.
10734 * window.h (struct window): Likewise.
10735 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10736 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10737 * buffer.c (init_buffer_once): Likewise.
10738 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10740 * process.c (Fformat_network_address): Use local var for size,
10743 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10745 Make the Lisp reader and string-to-float more consistent (Bug#8525)
10746 * data.c (atof): Remove decl; no longer used or needed.
10747 (digit_to_number): Move to lread.c.
10748 (Fstring_to_number): Use new string_to_number function, to be
10749 consistent with how the Lisp reader treats infinities and NaNs.
10750 Do not assume that floating-point numbers represent EMACS_INT
10751 without losing information; this is not true on most 64-bit hosts.
10752 Avoid double-rounding errors, by insisting on integers when
10753 parsing non-base-10 numbers, as the documentation specifies.
10754 * lisp.h (string_to_number): New decl, replacing ...
10755 (isfloat_string): Remove.
10756 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10757 (read1): Do not accept +. and -. as integers; this
10758 appears to have been a coding error. Similarly, do not accept
10759 strings like +-1e0 as floating point numbers. Do not report
10760 overflow for integer overflows unless the base is not 10 which
10761 means we have no simple and reliable way to continue.
10762 Break out the floating-point parsing into a new
10763 function string_to_number, so that Fstring_to_number parses
10764 floating point numbers consistently with the Lisp reader.
10765 (digit_to_number): Move here from data.c. Make it static inline.
10766 (E_CHAR, EXP_INT): Remove, replacing with ...
10767 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10768 (string_to_number): New function, replacing isfloat_string.
10769 This function checks for valid syntax and produces the resulting
10770 Lisp float number too. Rework it so that string-to-number
10771 no longer mishandles examples like "1.0e+". Use strtoumax,
10772 so that overflow for non-base-10 numbers is reported only when
10773 there's no portable and simple way to convert to floating point.
10775 * textprop.c (set_text_properties_1): Rewrite for clarity,
10776 and to avoid GCC warning about integer overflow.
10778 * intervals.h (struct interval): Use EMACS_INT for members
10779 where EMACS_UINT might cause problems. See
10780 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10781 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10782 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10784 (offset_intervals): Tell GCC not to worry about length overflow
10785 when negating a negative length.
10787 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10788 (overrun_check_free): Likewise.
10790 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10791 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10794 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10795 (gnutls_make_error): Rename local to avoid shadowing.
10796 (gnutls_emacs_global_deinit): ifdef out; not used.
10797 (Fgnutls_boot): Use const for pointer to readonly storage.
10798 Comment out unused local. Fix pointer signedness problems.
10800 * lread.c (openp): Don't stuff size_t into an 'int'.
10801 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10802 about possible signed overflow.
10804 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10805 (GDK_KEY_g): Don't define if already defined.
10806 (xg_prepare_tooltip): Avoid pointer signedness problem.
10807 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10809 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10810 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
10812 * xfns.c (Fx_window_property): Simplify a bit,
10813 to make a bit faster and to avoid GCC 4.6.0 warning.
10814 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10816 * fns.c (internal_equal): Don't assume size_t fits in int.
10818 * alloc.c (compact_small_strings): Tighten assertion a little.
10820 Replace pEd with more-general pI, and fix some printf arg casts.
10821 * lisp.h (pI): New macro, generalizing old pEd macro to other
10822 conversion specifiers. For example, use "...%"pI"d..." rather
10823 than "...%"pEd"...".
10824 (pEd): Remove. All uses replaced with similar uses of pI.
10825 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10826 * alloc.c (check_pure_size): Don't overflow by converting size to int.
10827 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10828 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10829 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10830 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10831 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10833 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10834 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10835 * print.c (safe_debug_print, print_object): Likewise.
10836 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10838 Use pI instead of if-then-else-abort. Use %p to avoid casts,
10839 avoiding the 0 flag, which is not portable.
10840 * process.c (Fmake_network_process): Use pI to avoid cast.
10841 * region-cache.c (pp_cache): Likewise.
10842 * xdisp.c (decode_mode_spec): Likewise.
10843 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
10844 behavior on 64-bit hosts with printf arg.
10845 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
10846 (x_stop_queuing_selection_requests): Likewise.
10847 (x_get_window_property): Don't truncate byte count to an 'int'
10850 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
10851 here, since it parses constructs like leading '-' and spaces,
10852 which are not wanted; and it overflows with large numbers.
10853 Instead, simply match F[0-9]+, which is what is wanted anyway.
10855 * alloc.c: Remove unportable assumptions about struct layout.
10856 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
10857 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
10858 (allocate_vectorlike, make_pure_vector): Use the new macros,
10859 plus offsetof, to remove unportable assumptions about struct layout.
10860 These assumptions hold on all porting targets that I know of, but
10861 they are not guaranteed, they're easy to remove, and removing them
10862 makes further changes easier.
10864 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
10865 This doesn't fix a bug but makes the code clearer.
10866 (string_overrun_cookie): Now const. Use initializers that
10867 don't formally overflow signed char, to avoid warnings.
10868 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
10869 can cause Emacs to crash when string overrun checking is enabled.
10870 (allocate_buffer): Don't assume sizeof (struct buffer) is a
10871 multiple of sizeof (EMACS_INT); it need not be, if
10872 alignof(EMACS_INT) < sizeof (EMACS_INT).
10873 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
10875 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
10877 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
10879 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
10881 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
10882 supposed to be handshaking. (Bug#8556)
10883 Reported by Paul Eggert <eggert@cs.ucla.edu>.
10885 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
10887 * lisp.h (Qdebug): List symbol.
10888 * eval.c (Qdebug): Restore global linkage.
10889 * keyboard.c (debug-on-event): New variable.
10890 (handle_user_signal): Break into debugger when debug-on-event
10891 matches the current signal symbol.
10893 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
10895 * alloc.c (check_sblock, check_string_bytes)
10896 (check_string_free_list): Convert to standard C.
10898 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
10900 * w32.c (emacs_gnutls_push): Fix typo.
10902 2011-04-25 Eli Zaretskii <eliz@gnu.org>
10904 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
10905 "cast to pointer from integer of different size".
10907 Improve doprnt and its use in verror. (Bug#8545)
10908 * doprnt.c (doprnt): Document the set of format control sequences
10909 supported by the function. Use SAFE_ALLOCA instead of always
10912 * eval.c (verror): Don't limit the buffer size at size_max-1, that
10913 is one byte too soon. Don't use xrealloc; instead xfree and
10916 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
10918 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
10921 * gnutls.c: Renamed global_initialized to
10922 gnutls_global_initialized. Added internals for the
10923 :verify-hostname-error, :verify-error, and :verify-flags
10924 parameters of `gnutls-boot' and documented those parameters in the
10925 docstring. Start callback support.
10926 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
10927 unless a fatal error occurred. Call gnutls_alert_send_appropriate
10928 on error. Return error code.
10929 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
10930 (emacs_gnutls_read): Likewise.
10931 (Fgnutls_boot): Return handshake error code.
10932 (emacs_gnutls_handle_error): New function.
10933 (wsaerror_to_errno): Likewise.
10935 * w32.h (emacs_gnutls_pull): Add prototype.
10936 (emacs_gnutls_push): Likewise.
10938 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
10939 (emacs_gnutls_push): Likewise.
10941 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
10943 * process.c (wait_reading_process_output): Check if GnuTLS

11450 * font.c (font_close_object): Now static.
11451 * font.h (font_close_object): Remove.
11452 * fontset.c (FONTSET_OBJLIST): Remove.
11453 (free_realized_fontset) #if-0 the body, which does nothing.
11454 (face_suitable_for_char_p): #if-0, as it's never called.
11455 * fontset.h (face_suitable_for_char_p): Remove decl.
11456 * xfaces.c (face_at_string_position):
11457 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
11458 since 0 is always ASCII.
11460 * fns.c (weak_hash_tables): Now static.
11462 * fileio.c: Make symbols static if they're not exported.

11481 * editfns.c, lisp.h (get_operating_system_release): Remove.
11482 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
11483 worth the hassle of breaking this out.
11485 * xterm.c: Make symbols static if they're not exported.
11486 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
11487 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

11589 * buffer.c (buffer_count): Remove unused var.

11593 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
11594 * dispextern.h (bidi_dump_cached_states): Remove, since it's
11595 exported only to the debugger.

11598 * atimer.h (run_all_atimers): Remove; not exported.
11600 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
11601 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
11602 was inaccessible from Lisp.
11603 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
11604 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
11606 alloc.c: Import and export fewer symbols, and remove unused items.
11607 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
11609 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
11610 it's not optimized away by whole-program optimization.
11611 (message_enable_multibyte, free_misc): Remove.
11612 (catchlist, handlerlist, mark_backtrace):
11613 Declare only if BYTE_MARK_STACK.

11622 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
11623 (mark_backtrace): Define only if BYTE_MARK_STACK.
11624 * xdisp.c (message_enable_multibyte): Now static.
11626 Declare Lisp_Object Q* variables to be 'static' if not exported.
11627 This makes it easier for human readers (and static analyzers)
11628 to see whether these variables are used from other modules.
11629 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
11630 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

11639 Remove decls of unexported vars.
11640 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
11642 * lisp.h (DEFINE_FUNC): Make sname 'static'.
11644 Make Emacs functions such as Fatom 'static' by default.
11645 This makes it easier for human readers (and static analyzers)
11646 to see whether these functions can be called from other modules.
11647 DEFUN now defines a static function. To make the function external
11648 so that it can be used in other C modules, use the new macro DEFUE.
11649 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
11650 (Finit_image_library):
11651 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
11652 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
11653 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
11654 Remove decls, since these functions are now static.
11655 (Funintern, Fget_internal_run_time): New decls, since these functions
11656 were already external.
11658 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
11659 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

11665 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
11666 Mark functions with DEFUE instead of DEFUN,
11667 if they are used in other modules.
11668 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
11669 decls for now-static functions.
11670 * buffer.h (Fdelete_overlay): Remove decl.
11671 * callproc.c (Fgetenv_internal): Mark as internal.
11672 * composite.c (Fremove_list_of_text_properties): Remove decl.

11679 * fileio.c (Fmake_symbolic_link): New forward static decl.
11680 * image.c (Finit_image_library): New forward static decl.
11681 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
11682 * intervals.h (Fprevious_property_change):
11683 (Fremove_list_of_text_properties): Remove decls.
11684 * keyboard.c (Fthis_command_keys): Remove decl.
11685 (Fcommand_execute): New forward static decl.

11701 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
11703 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
11706 2011-04-13 Eli Zaretskii <eliz@gnu.org>
11708 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
11709 when at ZV. (Bug#8487)
11711 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
11713 * charset.c (Fclear_charset_maps): Use xfree instead of free.
11715 * keyboard.c (parse_tool_bar_item): Likewise.
11716 * sound.c (sound_cleanup, alsa_close): Likewise.
11717 * termcap.c (tgetent): Likewise.
11718 * xfns.c (x_default_font_parameter): Likewise.
11719 * xsettings.c (read_and_apply_settings): Likewise.
11721 * alloc.c (overrun_check_malloc, overrun_check_realloc)
11722 (overrun_check_free): Protoize.
11724 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
11726 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
11727 since callers should never pass a negative size.
11728 Change the signature to match that of plain 'read' and 'write'; see
11729 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
11730 * lisp.h: Update prototypes of emacs_write and emacs_read.
11732 2011-04-11 Eli Zaretskii <eliz@gnu.org>
11734 * xdisp.c (redisplay_window): Don't try to determine the character
11735 position of the scroll margin if the window start point w->startp
11736 is outside the buffer's accessible region. (Bug#8468)
11738 2011-04-10 Eli Zaretskii <eliz@gnu.org>
11740 Fix write-region and its subroutines for buffers > 2GB.
11741 * fileio.c (a_write, e_write): Modify declaration of arguments and
11742 local variables to support buffers larger than 2GB.
11743 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
11745 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
11746 argument, local variables, and return value.
11748 * lisp.h: Update prototypes of emacs_write and emacs_read.
11750 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
11752 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
11754 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
11756 Fix more problems found by GCC 4.6.0's static checks.
11758 * xdisp.c (vmessage): Use a better test for character truncation.
11760 * charset.c (load_charset_map): <, not <=, for optimization,
11761 and to avoid potential problems with integer overflow.
11762 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11763 * casetab.c (set_identity, shuffle): Likewise.
11764 * editfns.c (Fformat): Likewise.
11765 * syntax.c (skip_chars): Likewise.
11767 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11768 This also lets GCC 4.6.0 generate slightly better loop code.
11770 * callint.c (Fcall_interactively): <, not <=, for optimization.
11771 (Fcall_interactively): Count the number of arguments produced,
11772 not the number of arguments given. This is simpler and lets GCC
11773 4.6.0 generate slightly better code.
11775 * ftfont.c: Distingish more carefully between FcChar8 and char.
11776 The previous code passed unsigned char * to a functions like
11777 strlen and xstrcasecmp that expect char *, which does not
11778 conform to the C standard.
11779 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11780 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11781 char * when the C standard requires it.
11783 * keyboard.c (read_char): Remove unused var.
11785 * eval.c: Port to Windows vsnprintf (Bug#8435).
11786 Include <limits.h>.
11787 (SIZE_MAX): Define if the headers do not.
11788 (verror): Do not give up if vsnprintf returns a negative count.
11789 Instead, grow the buffer. This ports to Windows vsnprintf, which
11790 does not conform to C99. Problem reported by Eli Zaretskii.
11791 Also, simplify the allocation scheme, by avoiding the need for
11792 calling realloc, and removing the ALLOCATED variable.
11794 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11796 Remove invocations of doprnt, as Emacs now uses vsnprintf.
11797 But keep the doprint source code for now, as we might revamp it
11798 and use it again (Bug#8435).
11799 * lisp.h (doprnt): Remove.
11800 * Makefile.in (base_obj): Remove doprnt.o.
11801 * deps.mk (doprnt.o): Remove.
11803 error: Print 32- and 64-bit integers portably (Bug#8435).
11804 Without this change, on typical 64-bit hosts error ("...%d...", N)
11805 was used to print both 32- and 64-bit integers N, which relied on
11806 undefined behavior.
11807 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11808 * lisp.h (error, verror): Mark as printf-like functions.
11809 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11810 Report overflow in size calculations when allocating printf buffer.
11811 Do not truncate output string at its first null byte.
11812 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11813 Truncate the output at a character boundary, since vsnprintf does not
11815 * charset.c (check_iso_charset_parameter): Convert internal
11816 character to string before calling 'error', since %c now has the
11818 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11819 overflow when computing char to be passed to 'error'. Do not
11820 pass Lisp_Object to 'error'; pass the integer instead.
11821 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11822 formatted with plain %d.
11824 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11826 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.

11838 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11839 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11840 return ssize_t not "int", and use size_t as the buffer length.
11841 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11842 * gnutls.h: Update declarations.
11843 * process.c (read_process_output): Use ssize_t, to match.

11959 This avoids several warnings with gcc -Wstrict-overflow.
11960 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
11961 directly, rather than having caller test rule sign. This avoids
11962 some unnecessary tests.
11963 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
11964 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
11965 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
11967 * xfont.c (xfont_text_extents): Remove var that was set but not used.
11968 (xfont_open): Avoid unnecessary tests.
11970 * composite.c (composition_gstring_put_cache): Use unsigned integer.

11982 since the condition is always true at first.
11984 * intervals.c (graft_intervals_into_buffer): Mark var as used.
11985 (interval_deletion_adjustment): Return unsigned value.
11988 * process.c (list_processes_1, create_pty, read_process_output):

12015 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12017 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12018 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12019 can always succeed if overflow has undefined behavior.
12021 * search.c (boyer_moore, wordify): Remove vars set but not used.
12022 (wordify): Omit three unnecessary tests.
12024 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

12036 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12037 Check for integer overflow on size calculations.
12039 * buffer.c (Fprevious_overlay_change): Remove var that is set
12042 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12043 Remove vars that are set but not used.
12044 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12045 (timer_check_2): Mark vars as initialized.
12047 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12049 * image.c (lookup_image): Remove var that is set but not used.

12052 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12053 that are set but not used.
12055 * xfns.c (make_invisible_cursor): Don't return garbage
12056 if XCreateBitmapFromData fails (Bug#8410).
12058 * xselect.c (x_get_local_selection, x_handle_property_notify):
12059 Remove vars that are set but not used.
12061 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12062 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

12065 Remove var that is set but not used.
12066 (scroll_bar_windows_size): Now size_t, not int.
12067 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12068 Check for overflow.

12079 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12080 (decode_coding_charset): Remove vars that are set but not used.

12083 that is set but not used.
12085 * print.c (print_object): Remove var that is set but not used.
12087 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12088 The gnulib version avoids calling malloc in the usual case,
12089 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12090 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12091 * filelock.c (current_lock_owner): Likewise.
12092 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12093 * sysdep.c: Include allocator.h, careadlinkat.h.
12094 (emacs_no_realloc_allocator): New static constant.
12095 (emacs_readlink): New function.
12096 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12097 ../lib/careadlinkat.h.
12099 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12101 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12102 first non-nil return value).

12118 (get_per_char_metric): Remove parameter `f', unused since
12119 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

12163 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12164 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12165 (FletX, Flet): Obey lexical binding.
12166 (Fcommandp): Handle closures.
12167 (Feval): New `lexical' arg.
12168 (eval_sub): New function extracted from Feval. Use it almost
12169 everywhere where Feval was used. Look up vars in lexical env.
12171 (Ffunctionp): Move from subr.el.
12172 (Ffuncall): Handle closures.
12173 (apply_lambda): Remove `eval_flags'.
12174 (funcall_lambda): Handle closures and new byte-code-functions.
12175 (Fspecial_variable_p): New function.
12176 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12177 but without exporting it to Lisp.
12179 * doc.c (Fdocumentation, store_function_docstring):
12180 * data.c (Finteractive_form): Handle closures.
12182 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12185 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12187 (exec_byte_code): New function extracted from Fbyte_code to handle new
12188 calling convention for byte-code-functions. Add new byte-codes.
12190 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

12202 Limit scrolling to 100 screen lines.
12203 (redisplay_window): Even when falling back on "recentering",
12204 position point in the window according to scroll-conservatively,
12205 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12207 (try_scrolling): When point is above the window, allow searching
12208 as far as scroll_max, or one screenful, to compute vertical
12209 distance from PT to the scroll margin position. This prevents
12210 try_scrolling from unnecessarily failing when
12211 scroll-conservatively is set to a value slightly larger than the
12212 window height. Clean up the case of PT below the margin at bottom
12213 of window: scroll_max can no longer be INT_MAX. When aggressive
12214 scrolling is in use, don't let point enter the opposite scroll
12215 margin as result of the scroll.
12216 (syms_of_xdisp) <scroll-conservatively>: Document the
12217 threshold of 100 lines for never-recentering scrolling.

12224 (message_log_check_duplicate): Remove parameters `prev_bol' and
12225 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12226 (redisplay_internal): Remove parameter `preserve_echo_area',
12227 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12229 * indent.c (Fvertical_motion):
12230 * window.c (window_scroll_pixel_based, Frecenter):
12231 Don't pass `need_y_p' to `move_it_by_lines'.
12233 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12235 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12236 steal a few bits to be more compact.
12237 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12238 Remove unneeded casts.
12240 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12242 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12244 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12245 binding" message (bug#7967).

12251 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12252 Remove unused local var.
12254 * editfns.c (Fmessage_box): Remove unused local var.
12256 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12257 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12258 Omit unused local vars.
12259 * window.c (shrink_windows): Omit unused local var.
12260 * menu.c (digest_single_submenu): Omit unused local var.
12261 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12262 Omit unused local var.
12264 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12265 Don't assume string length fits in int.
12266 (keyremap_step, read_key_sequence): Use size_t for sizes.
12267 (read_key_sequence): Don't check last_real_key_start redundantly.

12270 instead of alloca (Bug#8344).
12272 * eval.c (Fbacktrace): Don't assume nargs fits in int.

12280 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12282 * cm.c (calccost): Turn while-do into do-while, for clarity.
12284 * keyboard.c (syms_of_keyboard): Use the same style as later
12285 in this function when indexing through an array. This also
12286 works around GCC bug 48267.
12288 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12290 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12292 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12293 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12295 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12296 This avoids undefined behavior on integer overflow, and is a bit
12297 more convenient anyway since it is compared to a size_t variable.
12299 Variadic C functions now count arguments with size_t, not int.
12300 This avoids an unnecessary limitation on 64-bit machines, which
12301 caused (substring ...) to crash on large vectors (Bug#8344).
12302 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
12303 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
12304 All variadic functions and their callers changed accordingly.
12305 (struct gcpro.nvars): Now size_t, not int. All uses changed.

12307 * editfns.c (general_insert_function): Likewise.
12308 * eval.c (struct backtrace.nargs, interactive_p)
12309 (internal_condition_case_n, run_hook_with_args, apply_lambda)
12310 (funcall_lambda, mark_backtrace): Likewise.
12311 * fns.c (concat): Likewise.
12312 * frame.c (x_set_frame_parameters): Likewise.
12313 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12314 0 if not found, not -1. All callers changed.
12316 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12317 (stack_copy_size): Now size_t, not int.
12318 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

12323 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12324 All callers changed.
12326 * lisp.h (multibyte_char_to_unibyte):
12327 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12328 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

12336 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12338 * keyboard.c (safe_run_hook_funcall): New function.
12339 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12340 don't set the hook to nil, but remove the offending function instead.
12341 (Qcommand_hook_internal): Remove, unused.
12342 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12343 Vcommand_hook_internal.
12345 * eval.c (enum run_hooks_condition): Remove.
12346 (funcall_nil, funcall_not): New functions.
12347 (run_hook_with_args): Call each function through a `funcall' argument.

12357 * print.c (strout): Remove parameter `multibyte', unused since
12358 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
12360 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
12361 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
12362 All callers changed.
12364 * w32.c (_wsa_errlist): Use braces for struct initializers.
12366 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
12367 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
12368 All callers changed.

12374 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
12375 All callers changed.
12377 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12379 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
12381 2011-03-27 Anders Lindgren <andlind@gmail.com>
12383 * nsterm.m (ns_menu_bar_is_hidden): New variable.
12384 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
12385 (ns_update_auto_hide_menu_bar): New functions.
12386 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

12390 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
12392 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12394 * nsmenu.m (runDialogAt): Remove argument to timer_check.
12396 2011-03-27 Glenn Morris <rgm@gnu.org>
12398 * syssignal.h: Replace RETSIGTYPE with void.
12399 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
12400 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
12401 Replace SIGTYPE with void everywhere.

12405 2011-03-26 Eli Zaretskii <eliz@gnu.org>
12407 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
12408 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
12410 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
12412 * w32.c (read_unc_volume): Use parameter `henum', instead of
12413 global variable `wget_enum_handle'.
12415 * keymap.c (describe_vector): Remove parameters `indices' and
12416 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

12522 * callint.c (Fcall_interactively):
12523 * buffer.c (Fkill_all_local_variables):
12524 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12526 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
12527 unconditionally since it does the check itself.
12529 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12531 Fix more problems found by GCC 4.5.2's static checks.
12533 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12534 the first time through the loop, since we know p0 < p1 then.
12535 This also avoids a gcc -Wstrict-overflow warning.
12537 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12538 leading to a memory leak, possible in functions like
12539 load_charset_map_from_file that can allocate an unbounded number
12540 of objects (Bug#8318).
12542 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12543 that could (at least in theory) be that large.
12545 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12546 This is less likely to overflow, and avoids undefined behavior if
12547 overflow does occur. All callers changed. Use strtoul to scan
12548 for the unsigned long integer.
12549 (pint2hrstr): Simplify and tune code slightly.
12550 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

12560 * fileio.c (Fcopy_file): Report error if fchown or fchmod
12563 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12565 * process.c (Fmake_network_process): Use socklen_t, not int,
12566 where POSIX says socklen_t is required in portable programs.
12567 This fixes a porting bug on hosts like 64-bit HP-UX, where
12568 socklen_t is wider than int (Bug#8277).
12569 (Fmake_network_process, server_accept_connection):
12570 (wait_reading_process_output, read_process_output):
12573 * process.c: Rename or move locals to avoid shadowing.

12583 Make tparam.h and terminfo.c consistent.
12584 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12585 Include tparam.h instead, since it declares them.
12586 * cm.h (PC): Remove extern decl; tparam.h now does this.
12587 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12588 * terminfo.c: Include tparam.h, to check interfaces.
12589 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12590 (tparam): Adjust signature to match interface in tparam.h;
12591 this removes some undefined behavior. Check that outstring and len
12592 are zero, which they always are with Emacs.
12593 * tparam.h (PC, BC, UP): New extern decls.
12595 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12596 (xftfont_open): Rename locals to avoid shadowing.
12598 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

12601 (ftfont_list): Remove unused local.
12602 (get_adstyle_property, ftfont_pattern_entity):
12603 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
12604 Rename locals to avoid shadowing.
12606 * xfont.c (xfont_list_family): Mark var as initialized.
12608 * xml.c (make_dom): Now static.
12610 * composite.c (composition_compute_stop_pos): Rename local to
12612 (composition_reseat_it): Remove unused locals.
12613 (find_automatic_composition, composition_adjust_point): Likewise.
12614 (composition_update_it): Mark var as initialized.
12615 (find_automatic_composition): Mark vars as initialized,
12616 with a FIXME (Bug#8290).
12618 character.h: Rename locals to avoid shadowing.
12619 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
12620 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
12621 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
12622 (BUF_DEC_POS): Be more systematic about renaming local temporaries
12623 to avoid shadowing.
12625 * textprop.c (property_change_between_p): Remove; unused.
12627 * intervals.c (interval_start_pos): Now static.
12629 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
12631 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
12632 Rename locals to avoid shadowing.
12634 * sound.c (wav_play, au_play, Fplay_sound_internal):
12635 Fix pointer signedness.
12636 (alsa_choose_format): Remove unused local var.
12637 (wav_play): Initialize a variable to 0, to prevent undefined
12638 behavior (Bug#8278).
12640 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12642 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12644 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12645 clobbering (Bug#8298).
12646 * sysdep.c (sys_subshell): Likewise.
12647 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12649 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12650 This should get cleaned up, so that child_setup has the
12651 same signature on all platforms.
12653 * callproc.c (call_process_cleanup): Now static.
12654 (relocate_fd): Rename locals to avoid shadowing.
12656 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
12658 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
12659 not to be necessary, and produces flickering.
12661 2011-03-20 Glenn Morris <rgm@gnu.org>
12663 * config.in: Remove file.
12665 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
12667 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
12668 are now in src/globals.h.

12679 * xfaces.c (Fx_load_color_file):
12680 Read color file from absolute filename (bug#8250).

12686 2011-03-17 Eli Zaretskii <eliz@gnu.org>
12688 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

12695 (sigchld_handler): Now static.
12697 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
12698 That way, the code declares only the vars that it needs.
12699 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
12700 * s/cygwin.h (PTY_ITERATION): Likewise.
12701 * s/darwin.h (PTY_ITERATION): Likewise.

12704 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
12705 * process.c (allocate_pty): Don't declare stb unless it's needed.
12707 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
12708 (CONSTANTLIM): Remove; unused.
12709 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
12710 Define only if needed.
12712 * unexelf.c (unexec): Name an expression,
12713 to avoid gcc -Wbad-function-cast warning.
12714 Use a different way to cause a compilation error if anyone uses
12715 n rather than nn, a way that does not involve shadowing.
12716 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
12718 * deps.mk (unexalpha.o): Remove; unused.
12720 New file unexec.h, the (simple) interface for unexec (Bug#8267).
12721 * unexec.h: New file.
12722 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
12723 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
12724 Depend on unexec.h.
12725 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
12726 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
12727 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

12784 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
12785 some of which prompt warnings from gcc -Wbad-function-cast.
12786 (Fformat_time_string, Fencode_time, Finsert_char):
12787 (Ftranslate_region_internal, Fformat):

12815 (Fmemory_limit): Cast sbrk's returned value to char *.
12817 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

12822 Use functions, not macros, for up- and down-casing (Bug#8254).
12823 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12824 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
12825 to use the following functions instead of these macros.
12826 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
12827 EMACS_INT, since callers assume the returned value fits in int.
12828 (upcase1): Likewise, for UPCASE_TABLE.
12829 (uppercasep, lowercasep, upcase): New static inline functions.
12830 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

12840 (regex_compile, re_match_2_internal): Mark locals as initialized.
12841 (RETALLOC_IF): Define only if needed.
12842 (WORDCHAR_P): Likewise. This one is never needed, but is used
12843 only in a comment talking about a compiler bug, so put inside
12844 the #if 0 of that comment.
12845 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
12846 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

12873 New macros, so that the caller can use some names other than
12874 gcpro1, gcpro2, etc.
12875 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
12877 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
12878 argument, for consistency with GCPRO2_VAR, etc: it is now the
12879 prefix of the variable, not the variable itself. All uses
12881 * dired.c (directory_files_internal, file_name_completion):
12882 Rename locals to avoid shadowing.
12884 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
12885 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
12886 dired.c's scmp function, had undefined behavior.
12887 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12888 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
12889 * buffer.h: ... to here, because these macros use current_buffer,
12890 and the new implementation with inline functions needs to have
12891 current_buffer in scope now, rather than later when the macros
12893 (downcase, upcase1): New static inline functions.
12894 (DOWNCASE, UPCASE1): Reimplement using these functions.
12895 This avoids undefined behavior in expressions like
12896 DOWNCASE (x) == DOWNCASE (y), which previously suffered
12897 from race conditions in accessing the global variables
12898 case_temp1 and case_temp2.
12899 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
12900 * lisp.h (case_temp1, case_temp2): Remove their decls.
12901 * character.h (ASCII_CHAR_P): Move from here ...
12902 * lisp.h: ... to here, so that the inline functions mentioned
12903 above can use them.

12907 * fileio.c (file_name_as_directory, directory_file_name):

12910 (file_name_as_directory): Use const pointers when appropriate.
12911 (Fexpand_file_name): Likewise. In particular, newdir might
12912 point at constant storage, so make it a const pointer.

12914 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
12916 (Fset_file_times, Finsert_file_contents, auto_save_error):

12921 to avoid shadowing.
12923 * marker.c (bytepos_to_charpos): Remove; unused.
12925 * lisp.h (verify_bytepos, count_markers): New decls,
12926 so that gcc does not warn that these functions aren't declared.
12928 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
12929 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
12930 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
12931 (copy_text): Remove unused local var.

12934 (lock_file_1): Rename local to avoid shadowing.
12936 * buffer.c (fix_overlays_before): Mark locals as initialized.
12937 (fix_start_end_in_overlays): Likewise. This function should be
12938 simplified by using pointers-to-pointers, but that's a different
12940 (switch_to_buffer_1): Now static.
12941 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
12942 (report_overlay_modification): Rename locals to avoid shadowing.

12945 Fix pointer signedness issue.
12946 (sys_subshell): Mark local as volatile if checking for lint,
12947 to suppress a gcc -Wclobbered warning that does not seem to be right.
12948 (MAXPATHLEN): Define only if needed.
12950 * process.c (serial_open, serial_configure): Move decls from here ...
12951 * systty.h: ... to here, so that they can be checked.
12953 * fns.c (get_random, seed_random): Move extern decls from here ...
12954 * lisp.h: ... to here, so that they can be checked.
12956 * sysdep.c (reset_io): Now static.

12965 (describe_map_tree):
12966 Rename locals to avoid shadowing.

13115 For example, without this patch (encode-time 0 0 0 1 1
13116 1152921504606846976) returns the obviously-bogus value (-948597
13117 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
13118 reports time overflow. See
