1 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3 * image.c: Various fixes to ImageMagick code comments.
4 (Fimagemagick_types): Doc fix.
6 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
8 Minor fixes prompted by GCC 4.6.0 warnings.
10 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13 (x_clipboard_manager_save_all): Move extern decl to ...
14 * xterm.h: ... here, so that it can be checked for consistency.
16 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18 * xselect.c (x_clipboard_manager_save_frame)
19 (x_clipboard_manager_save_all): New functions.
20 (Fx_clipboard_manager_save): Lisp function deleted.
22 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
23 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
25 * xterm.h: Update prototype.
27 2011-05-28 William Xu <william.xwl@gmail.com>
29 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
32 2011-05-28 Jim Meyering <meyering@redhat.com>
34 Avoid a sign-extension bug in crypto_hash_function.
35 * fns.c (to_uchar): Define.
36 (crypto_hash_function): Use it to convert some newly-signed
37 variables to unsigned, to avoid sign-extension bugs. For example,
38 without this change, (md5 "truc") would evaluate to
39 45723a2aff78ff4fff7fff1114760e62 rather than the expected
40 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
41 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
43 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
45 Integer overflow fixes.
47 * dbusbind.c: Serial number integer overflow fixes.
48 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
49 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
50 to hold a serial number that is too large for a fixnum.
51 (Fdbus_method_return_internal, Fdbus_method_error_internal):
52 Check for serial numbers out of range. Decode any serial number
53 that was so large that it became a float. (Bug#8722)
55 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
56 (Fdbus_call_method, Fdbus_call_method_asynchronously):
57 Use XFASTINT rather than XUINT when numbers are nonnegative.
58 (xd_append_arg, Fdbus_method_return_internal):
59 (Fdbus_method_error_internal): Likewise. Also, for unsigned
60 arguments, check that Lisp number is nonnegative, rather than
61 silently wrapping negative numbers around. (Bug#8722)
62 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
65 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
67 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
69 ccl: add integer overflow checks
70 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
71 (IN_INT_RANGE): New macros.
72 (ccl_driver): Use them to check for integer overflow when
73 decoding a CCL program. Many of the new checks are whether XINT (x)
74 fits in int; it doesn't always, on 64-bit hosts. The new version
75 doesn't catch all possible integer overflows, but it's an
76 improvement. (Bug#8719)
78 * alloc.c (make_event_array): Use XINT, not XUINT.
79 There's no need for unsigned here.
81 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
82 This follows up to the 2011-05-06 change that substituted uintptr_t
83 for EMACS_INT. This case wasn't caught back then.
85 Rework Fformat to avoid integer overflow issues.
86 * editfns.c: Include <float.h> unconditionally, as it's everywhere
87 now (part of C89). Include <verify.h>.
88 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
89 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
90 (Fformat): Avoid the prepass trying to compute sizes; it was only
91 approximate and thus did not catch overflow reliably. Instead, walk
92 through the format just once, formatting and computing sizes as we go,
93 checking for integer overflow at every step, and allocating a larger
94 buffer as needed. Keep track separately whether the format is
95 multibyte. Keep only the most-recently calculated precision, rather
96 than them all. Record whether each argument has been converted to
97 string. Use EMACS_INT, not int, for byte and char and arg counts.
98 Support field widths and precisions larger than INT_MAX. Avoid
99 sprintf's undefined behavior with conversion specifications such as %#d
100 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
101 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
102 formatting out-of-range floating point numbers with int
105 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
107 * data.c: Avoid integer truncation in expressions involving floats.
108 * data.c: Include <intprops.h>.
109 (arith_driver): When there's an integer overflow in an expression
110 involving floating point, convert the integers to floating point
111 so that the resulting value does not suffer from catastrophic
112 integer truncation. For example, on a 64-bit host (* 4
113 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
114 Do not rely on undefined behavior after integer overflow.
116 merge count_size_as_multibyte, parse_str_to_multibyte
117 * character.c, character.h (count_size_as_multibyte):
118 Renamed from parse_str_to_multibyte; all uses changed.
119 Check for integer overflow.
120 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
121 since it's now a duplicate of the other. This is more of
122 a character than a buffer op, so better that it's in character.c.
123 * fns.c, print.c: Adjust to above changes.
125 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
127 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
129 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
131 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
132 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
133 (x_clipboard_manager_save): Now static.
134 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
136 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
137 (crypto_hash_function): Now static.
138 Fix pointer signedness problems. Avoid unnecessary initializations.
140 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
142 * termhooks.h (Vselection_alist): Make it terminal-local.
144 * terminal.c (create_terminal): Initialize it.
146 * xselect.c: Support for clipboard managers.
147 (Vselection_alist): Move to termhooks.h as terminal-local var.
148 (LOCAL_SELECTION): New macro.
149 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
150 (symbol_to_x_atom): Remove gratuitous arg.
151 (x_handle_selection_request, lisp_data_to_selection_data)
152 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
153 (x_own_selection, x_get_local_selection, x_convert_selection): New
154 arg, specifying work frame. Use terminal-local Vselection_alist.
155 (some_frame_on_display): Delete unused function.
156 (Fx_own_selection_internal, Fx_get_selection_internal)
157 (Fx_disown_selection_internal, Fx_selection_owner_p)
158 (Fx_selection_exists_p): New optional frame arg.
159 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
160 (x_handle_selection_clear): Don't treat other terminals with the
161 same keyboard specially. Use the terminal-local Vselection_alist.
162 (x_clear_frame_selections): Use Frun_hook_with_args.
164 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
166 * xterm.h: Add support for those atoms.
168 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
170 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
171 (converted_selections, conversion_fail_tag): New global variables.
172 (x_selection_request_lisp_error): Free the above.
173 (x_get_local_selection): Remove unnecessary code.
174 (x_reply_selection_request): Args changed; handle arbitrary array
175 of converted selections stored in converted_selections. Separate
176 the XChangeProperty and SelectionNotify steps.
177 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
178 (x_convert_selection): New function.
179 (x_handle_selection_event): Simplify.
180 (x_get_foreign_selection): Don't ignore incoming requests while
181 waiting for an answer; this will fail when we implement
182 SAVE_TARGETS, and seems unnecessary anyway.
183 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
184 (Vx_sent_selection_functions): Doc fix.
186 2011-05-26 Leo Liu <sdl.web@gmail.com>
188 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
190 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
192 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
194 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
195 for fringe update if it has periodic bitmap.
196 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
197 and fringe_bitmap_periodic_p.
199 * fringe.c (get_fringe_bitmap_data): New function.
200 (draw_fringe_bitmap_1, update_window_fringes): Use it.
201 (update_window_fringes): Record periodicity of fringe bitmap in glyph
202 row. Mark glyph row for fringe update if periodicity changed.
204 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
205 for fringe update unless it has periodic bitmap.
207 2011-05-25 Kenichi Handa <handa@m17n.org>
209 * xdisp.c (get_next_display_element): Set correct it->face_id for
210 a static composition.
212 2011-05-24 Leo Liu <sdl.web@gmail.com>
215 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
217 * fns.c (crypto_hash_function, Fsha1): New function.
218 (Fmd5): Use crypto_hash_function.
219 (syms_of_fns): Add Ssha1.
221 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
223 * gnutls.c: Remove unused macros.
224 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
225 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
226 Remove macros that are defined and never used.
227 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
229 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
231 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
232 (Fx_get_selection_internal): Minor cleanup.
233 (Fx_own_selection_internal): Rename arguments for consistency with
236 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
238 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
240 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
242 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
244 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
246 * dispnew.c (scrolling_window): Don't exclude the case that the
247 last enabled row in the desired matrix touches the bottom boundary.
249 2011-05-21 Glenn Morris <rgm@gnu.org>
251 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
252 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
253 and add some more files.
255 2011-05-20 Eli Zaretskii <eliz@gnu.org>
257 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
258 report_file_error introduced by the change from 2011-05-07.
260 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
262 * systime.h (Time): Define only if emacs is defined.
263 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
264 where the include path doesn't have X11/X.h by default. See
265 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
267 2011-05-20 Kenichi Handa <handa@m17n.org>
269 * composite.c (find_automatic_composition): Fix previous change.
271 2011-05-20 Glenn Morris <rgm@gnu.org>
273 * lisp.mk: New file, split from Makefile.in.
274 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
276 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
278 2011-05-19 Glenn Morris <rgm@gnu.org>
280 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
281 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
282 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
283 (lisp): Set the order to that of loadup.el.
284 (shortlisp): Make it a copy of $lisp.
285 (SOME_MACHINE_LISP): Remove.
286 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
287 Use just $shortlisp, not $SOME_MACHINE_LISP too.
289 2011-05-18 Kenichi Handa <handa@m17n.org>
291 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
292 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
293 (find_automatic_composition): Mostly rewrite for efficiency.
295 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
297 * makefile.w32-in: Update dependencies.
299 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
301 * menu.c: Include limits.h (fixes the MS-Windows build broken by
304 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
306 Fix some integer overflow issues, such as string length overflow.
308 * insdel.c (count_size_as_multibyte): Check for string overflow.
310 * character.c (lisp_string_width): Check for string overflow.
311 Use EMACS_INT, not int, for string indexes and lengths; in
312 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
313 the resulting string length overflows an EMACS_INT; instead,
314 report a string overflow if no precision given. When checking for
315 precision exhaustion, use a check that cannot possibly have
316 integer overflow. (Bug#8675)
317 * character.h (lisp_string_width): Adjust to new signature.
319 * alloc.c (string_overflow): New function.
320 (Fmake_string): Use it. This doesn't change behavior, but saves
321 a few bytes and will simplify future changes.
322 * character.c (string_escape_byte8): Likewise.
323 * lisp.h (string_overflow): New decl.
325 Fixups, following up to the user-interface timestamp change.
326 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
327 for UI timestamps, instead of unsigned long.
328 * msdos.c (mouse_get_pos): Likewise.
329 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
330 * w32gui.h (Time): Define by including "systime.h" rather than by
331 declaring it ourselves. (Bug#8664)
333 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
334 * image.c (clear_image_cache): Likewise.
336 * term.c (term_mouse_position): Don't assume time_t wraparound.
338 Be more systematic about user-interface timestamps.
339 Before, the code sometimes used 'Time', sometimes 'unsigned long',
340 and sometimes 'EMACS_UINT', to represent these timestamps. This
341 change causes it to use 'Time' uniformly, as that's what X uses.
342 This makes the code easier to follow, and makes it easier to catch
343 integer overflow bugs such as Bug#8664.
344 * frame.c (Fmouse_position, Fmouse_pixel_position):
345 Use Time, not unsigned long, for user-interface timestamps.
346 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
347 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
348 * keyboard.h (last_event_timestamp): Likewise.
349 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
350 * menu.h (xmenu_show): Likewise.
351 * term.c (term_mouse_position): Likewise.
352 * termhooks.h (struct input_event.timestamp): Likewise.
353 (struct terminal.mouse_position_hook): Likewise.
354 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
355 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
356 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
357 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
359 * menu.h, termhooks.h: Include "systime.h", for Time.
361 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
362 Don't assume that the difference between two unsigned long values
363 can fit into an integer. At this point, we know button_down_time
364 <= event->timestamp, so the difference must be nonnegative, so
365 there's no need to cast the result if double-click-time is
366 nonnegative, as it should be; check that it's nonnegative, just in
367 case. This bug is triggered when events are more than 2**31 ms
368 apart (about 25 days). (Bug#8664)
370 * xselect.c (last_event_timestamp): Remove duplicate decl.
371 (x_own_selection): Remove needless cast to unsigned long.
373 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
374 that always fit in int. Use a sentinel instead of a counter, to
375 avoid a temp and to allay GCC's concerns about possible int overflow.
376 * frame.h (struct frame): Use int for menu_bar_items_used
377 instead of EMACS_INT, since it always fits in int.
379 * menu.c (grow_menu_items): Check for int overflow.
381 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
383 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
384 Before, the code was not consistent. These values cannot exceed
385 2**31 - 1 so there's no need to make them unsigned.
386 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
387 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
388 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
390 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
392 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
393 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
394 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
395 presumably because the widths might not match.
397 * window.c (size_window): Avoid needless test at loop start.
399 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
401 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
403 2011-05-12 Drew Adams <drew.adams@oracle.com>
405 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
407 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
409 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
410 `width' to `bar_area_x' and `bar_area_width', respectively.
411 (x_scroll_run): Take account of fringe background extension.
413 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
414 Rename local vars `left' and `width' to `bar_area_x' and
415 `bar_area_width', respectively.
416 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
417 background extension.
419 2011-05-10 Jim Meyering <meyering@redhat.com>
421 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
423 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
425 * image.c (Finit_image_library): Return t for built-in image types,
426 like pbm and xbm. (Bug#8640)
428 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
430 * w32menu.c (set_frame_menubar): Fix submenu allocation.
432 2011-05-07 Eli Zaretskii <eliz@gnu.org>
434 * w32console.c (Fset_screen_color): Doc fix.
435 (Fget_screen_color): New function.
436 (syms_of_ntterm): Defsubr it.
438 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
439 unlink the temporary file if Fcall_process didn't create it in the
441 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
442 child process will be redirected to a file specified with `:file'.
443 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
444 cue to call_process_cleanup not to close that handle.
446 2011-05-07 Ben Key <bkey76@gmail.com>
448 * makefile.w32-in: The bootstrap-temacs rule now makes use of
449 one of two shell specific rules, either bootstrap-temacs-CMD or
450 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
451 to the previous implementation of the bootstrap-temacs rule.
452 The bootstrap-temacs-CMD rule is similar to the previous
453 implementation of the bootstrap-temacs rule except that it
454 makes use of the ESC_CFLAGS variable instead of the CFLAGS
457 These changes, along with some changes to nt/configure.bat,
458 nt/gmake.defs, and nt/nmake.defs, are required to extend my
459 earlier fix to add support for --cflags and --ldflags options
460 that include quotes so that it works whether make uses cmd or
463 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
465 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
466 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
468 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
469 a string. Handle both cases.
470 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
471 (Fdbus_register_method): Use Qinvalid_function.
473 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
475 * makefile.w32-in: Update dependencies.
476 (LISP_H): Add inttypes.h and stdin.h.
477 (PROCESS_H): Add unistd.h.
479 2011-05-06 Eli Zaretskii <eliz@gnu.org>
481 * lread.c: Include limits.h (fixes the MS-Windows build broken by
482 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
484 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
486 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
488 * term.c (vfatal): Remove stray call to va_end.
489 It's not needed and the C Standard doesn't allow it here anyway.
491 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
492 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
494 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
497 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
499 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
501 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
503 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
505 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
507 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
508 * charset.c (Fdefine_charset_internal): Don't initialize
509 charset.code_space[15]. The value was garbage, on hosts with
510 32-bit int (Bug#8600).
512 * lread.c (read_integer): Be more consistent with string-to-number.
513 Use string_to_number to do the actual conversion; this avoids
514 rounding errors and fixes some other screwups. Without this fix,
515 for example, #x1fffffffffffffff was misread as -2305843009213693952.
516 (digit_to_number): Move earlier, for benefit of read_integer.
517 Return -1 if the digit is out of range for the base, -2 if it is
518 not a digit in any supported base. (Bug#8602)
520 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
522 * dispnew.c (scrolling_window): Return 1 if we scrolled,
523 to match comment at start of function. This also removes a
524 GCC warning about overflow in a 32+64-bit port.
526 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
528 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
529 Reported by Stefan Monnier in
530 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
531 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
532 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
534 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
535 (EMACS_UINTPTR): Likewise, with uintptr_t.
537 * lisp.h: Prefer 64-bit EMACS_INT if available.
538 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
539 on 32-bit hosts that have 64-bit int, so that they can access
541 However, temporarily disable this change unless the temporary
542 symbol WIDE_EMACS_INT is defined.
544 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
546 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
547 This removes an assumption that EMACS_INT and long are the same
548 width as pointers. The assumption is true for Emacs porting targets
549 now, but we want to make other targets possible.
550 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
551 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
552 In the rest of the code, change types of integers that hold casted
553 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
554 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
555 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
556 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
557 No need to cast type when ORing.
558 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
559 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
560 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
561 assume EMACS_INT is the same width as char *.
562 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
563 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
564 Remove no-longer-needed casts.
565 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
566 (xg_tool_bar_help_callback, xg_make_tool_item):
567 Use EMACS_INTPTR to hold an integer
568 that will be cast to void *; this can avoid a GCC warning
569 if EMACS_INT is not the same width as void *.
570 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
571 * xdisp.c (display_echo_area_1, resize_mini_window_1):
572 (current_message_1, set_message_1):
573 Use a local to convert to proper width without a cast.
574 * xmenu.c (dialog_selection_callback): Likewise.
576 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
577 Also, don't assume VALBITS / RAND_BITS is less than 5,
578 and don't rely on undefined behavior when shifting a 1 left into
580 * lisp.h (get_random): Change signature to match.
582 * lread.c (hash_string): Use size_t, not int, for hash computation.
583 Normally we prefer signed values; but hashing is special, because
584 it's better to use unsigned division on hash table sizes so that
585 the remainder is nonnegative. Also, size_t is the natural width
586 for hashing into memory. The previous code used 'int', which doesn't
587 retain enough info to hash well into very large tables.
588 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
590 * dbusbind.c: Don't possibly lose pointer info when converting.
591 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
592 Use XPNTR rather than XHASH, so that the high-order bits of
593 the pointer aren't lost when converting through void *.
595 * eval.c (Fautoload): Don't double-shift a pointer.
597 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
599 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
601 * gnutls.c (DEF_GNUTLS_FN):
602 * image.c (DEF_IMGLIB_FN): Make function pointers static.
604 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
606 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
609 2011-05-05 Eli Zaretskii <eliz@gnu.org>
611 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
612 New version that can reserve upto 2GB of heap space.
614 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
616 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
618 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
620 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
621 `gnutls_certificate_set_x509_key_file'.
623 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
625 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
628 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
630 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
631 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
632 Remove unused parameter `fildes'.
633 * process.c (read_process_output, send_process): Don't pass it.
635 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
637 Fix previous change: the library cache is defined in w32.c.
638 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
639 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
641 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
643 Implement dynamic loading of GnuTLS on Windows.
645 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
646 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
647 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
650 * gnutls.c (Qgnutls_dll): Define.
651 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
652 (gnutls_*): Declare function pointers.
653 (init_gnutls_functions): New function to initialize function pointers.
654 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
655 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
656 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
657 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
658 (emacs_gnutls_write, emacs_gnutls_read)
659 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
660 (Fgnutls_available_p): New function.
661 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
662 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
663 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
665 * image.c: Include w32.h.
666 (Vimage_type_cache): Delete.
667 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
668 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
669 (w32_delayed_load): Move to w32.c.
671 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
673 * w32.c (QCloaded_from, Vlibrary_cache): Define.
674 (w32_delayed_load): Move from image.c. When loading a library, record
675 its filename in the :loaded-from property of the library id.
676 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
677 Initialize and staticpro them.
678 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
680 * process.c: Include lisp.h before w32.h, not after.
681 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
682 instead of gnutls_record_check_pending.
684 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
686 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
688 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
689 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
692 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
694 * xterm.c (x_set_frame_alpha): Do not set property on anything
695 else than FRAME_X_OUTER_WINDOW (Bug#8608).
697 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
699 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
701 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
703 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
704 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
705 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

710 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
711 (Qgnutls_bootprop_callbacks_verify): Make static.
713 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
715 * callproc.c: Indentation fixup.
717 * sysdep.c (wait_for_termination_1): Make static.
718 (wait_for_termination, interruptible_wait_for_termination):
719 Move after wait_for_termination_1.
721 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
723 * sysdep.c (interruptible_wait_for_termination): New function
724 which is like wait_for_termination, but allows keyboard
727 * callproc.c (Fcall_process): Add (:file "file") as an option for
729 (Fcall_process_region): Ditto.
731 2011-04-30 Eli Zaretskii <eliz@gnu.org>
733 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
734 rather than `XVECTOR (FOO)->size'.
736 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
737 inttypes.h, as a gnulib replacement is used if it not available in
740 2011-04-21 Eli Zaretskii <eliz@gnu.org>
742 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
743 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
744 of MOST_POSITIVE_FIXNUM. (Bug#8528)
746 * coding.c (coding_alloc_by_realloc): Error out if destination
747 will grow beyond MOST_POSITIVE_FIXNUM.
748 (decode_coding_emacs_mule): Abort if there isn't enough place in
749 charbuf for the composition carryover bytes. Reserve an extra
750 space for up to 2 characters produced in a loop.
751 (decode_coding_iso_2022): Abort if there isn't enough place in
752 charbuf for the composition carryover bytes.
754 2011-04-21 Eli Zaretskii <eliz@gnu.org>
756 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
757 aborting when %lld or %lll format is passed.
758 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
759 %llo or %llx format is passed. (Bug#8545)
761 * window.c (window_scroll_line_based): Use a marker instead of
762 simple variables to record original value of point. (Bug#7952)
764 * doprnt.c (doprnt): Fix the case where a multibyte sequence
765 produced by %s or %c overflows available buffer space. (Bug#8545)
767 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
769 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
770 (SIZE_MAX): Move defn after all includes, as they might #define it.
772 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
774 * w32.c (init_environment): Warn about defaulting HOME to C:\.
776 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
778 * keyboard.c (Qdelayed_warnings_hook): Define.
779 (command_loop_1): Run `delayed-warnings-hook'
780 if Vdelayed_warnings_list is non-nil.
781 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
782 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
784 2011-04-28 Eli Zaretskii <eliz@gnu.org>
786 * doprnt.c (doprnt): Don't return value smaller than the buffer
787 size if the message was truncated. (Bug#8545).
789 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
791 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
792 (Fx_window_property): #if-0 the whole functions, not just the bodies.
794 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
796 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
798 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
800 * makefile.w32-in: Update dependencies.
802 2011-04-27 Eli Zaretskii <eliz@gnu.org>
804 Improve `doprnt' and its usage. (Bug#8545)
805 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
806 `format_end'. Remove support for %l as a conversion specifier.
807 Don't use xrealloc. Improve diagnostics when the %l size modifier
808 is used. Update the commentary.
810 * eval.c (verror): Simplify calculation of size_t.
812 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
815 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
817 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
820 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
822 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
823 This makes this file independent of the recent pseudovector change.
825 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
827 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
829 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
830 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
832 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
834 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
835 GCC 4.6.0 optimizes based on type-based alias analysis.
836 For example, if b is of type struct buffer * and v of type struct
837 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
838 != &v->size, and therefore "v->size = 1; b->size = 2; return
839 v->size;" must therefore return 1. This assumption is incorrect
840 for Emacs, since it type-puns struct Lisp_Vector * with many other
841 types. To fix this problem, this patch adds a new type struct
842 vectorlike_header that documents the constraints on layout of vectors
843 and pseudovectors, and helps optimizing compilers not get fooled
844 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
845 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
846 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
848 (XSETPVECTYPE): Rewrite in terms of new macro.
849 (XSETPVECTYPESIZE): New macro, specifying both type and size.
850 This is a bit clearer, and further avoids the possibility of
851 undesirable aliasing.
852 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
853 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
854 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
855 since Lisp_Subr is a special case (no "next" field).
856 (ASIZE): Now uses header.size rather than size.
857 All previous uses of XVECTOR (foo)->size replaced to use this macro,
858 to avoid the hassle of writing XVECTOR (foo)->header.size.
859 (struct vectorlike_header): New type.
860 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
861 object, to help avoid aliasing.
862 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
863 (SUBRP): Likewise, since Lisp_Subr is a special case.
864 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
865 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
866 (struct Lisp_Hash_Table): Combine first two members into a single
867 struct vectorlike_header member. All uses of "size" and "next" members
868 changed to be "header.size" and "header.next".
869 * buffer.h (struct buffer): Likewise.
870 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
871 * frame.h (struct frame): Likewise.
872 * process.h (struct Lisp_Process): Likewise.
873 * termhooks.h (struct terminal): Likewise.
874 * window.c (struct save_window_data, struct saved_window): Likewise.
875 * window.h (struct window): Likewise.
876 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
877 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
878 * buffer.c (init_buffer_once): Likewise.
879 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
881 * process.c (Fformat_network_address): Use local var for size,
884 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
886 Make the Lisp reader and string-to-float more consistent (Bug#8525)
887 * data.c (atof): Remove decl; no longer used or needed.
888 (digit_to_number): Move to lread.c.
889 (Fstring_to_number): Use new string_to_number function, to be
890 consistent with how the Lisp reader treats infinities and NaNs.
891 Do not assume that floating-point numbers represent EMACS_INT
892 without losing information; this is not true on most 64-bit hosts.
893 Avoid double-rounding errors, by insisting on integers when
894 parsing non-base-10 numbers, as the documentation specifies.
895 * lisp.h (string_to_number): New decl, replacing ...
896 (isfloat_string): Remove.
897 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
898 (read1): Do not accept +. and -. as integers; this
899 appears to have been a coding error. Similarly, do not accept
900 strings like +-1e0 as floating point numbers. Do not report
901 overflow for integer overflows unless the base is not 10 which
902 means we have no simple and reliable way to continue.
903 Break out the floating-point parsing into a new
904 function string_to_number, so that Fstring_to_number parses
905 floating point numbers consistently with the Lisp reader.
906 (digit_to_number): Move here from data.c. Make it static inline.
907 (E_CHAR, EXP_INT): Remove, replacing with ...
908 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
909 (string_to_number): New function, replacing isfloat_string.
910 This function checks for valid syntax and produces the resulting
911 Lisp float number too. Rework it so that string-to-number
912 no longer mishandles examples like "1.0e+". Use strtoumax,
913 so that overflow for non-base-10 numbers is reported only when
914 there's no portable and simple way to convert to floating point.
916 * textprop.c (set_text_properties_1): Rewrite for clarity,
917 and to avoid GCC warning about integer overflow.
919 * intervals.h (struct interval): Use EMACS_INT for members
920 where EMACS_UINT might cause problems. See
921 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
922 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
923 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
925 (offset_intervals): Tell GCC not to worry about length overflow
926 when negating a negative length.
928 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
929 (overrun_check_free): Likewise.
931 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
932 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
935 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
936 (gnutls_make_error): Rename local to avoid shadowing.
937 (gnutls_emacs_global_deinit): ifdef out; not used.
938 (Fgnutls_boot): Use const for pointer to readonly storage.
939 Comment out unused local. Fix pointer signedness problems.
941 * lread.c (openp): Don't stuff size_t into an 'int'.
942 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
943 about possible signed overflow.
945 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
946 (GDK_KEY_g): Don't define if already defined.

948 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
950 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
951 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
953 * xfns.c (Fx_window_property): Simplify a bit,
954 to make a bit faster and to avoid GCC 4.6.0 warning.
955 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
957 * fns.c (internal_equal): Don't assume size_t fits in int.
959 * alloc.c (compact_small_strings): Tighten assertion a little.
961 Replace pEd with more-general pI, and fix some printf arg casts.
962 * lisp.h (pI): New macro, generalizing old pEd macro to other
963 conversion specifiers. For example, use "...%"pI"d..." rather
965 (pEd): Remove. All uses replaced with similar uses of pI.
966 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
967 * alloc.c (check_pure_size): Don't overflow by converting size to int.
968 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
969 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
970 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
971 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
972 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on

975 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
976 * print.c (safe_debug_print, print_object): Likewise.
977 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
979 Use pI instead of if-then-else-abort. Use %p to avoid casts,
980 avoiding the 0 flag, which is not portable.
981 * process.c (Fmake_network_process): Use pI to avoid cast.
982 * region-cache.c (pp_cache): Likewise.
983 * xdisp.c (decode_mode_spec): Likewise.

987 (x_stop_queuing_selection_requests): Likewise.
988 (x_get_window_property): Don't truncate byte count to an 'int'
991 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
992 here, since it parses constructs like leading '-' and spaces,
993 which are not wanted; and it overflows with large numbers.
994 Instead, simply match F[0-9]+, which is what is wanted anyway.
996 * alloc.c: Remove unportable assumptions about struct layout.
997 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
998 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
999 (allocate_vectorlike, make_pure_vector): Use the new macros,
1000 plus offsetof, to remove unportable assumptions about struct layout.
1001 These assumptions hold on all porting targets that I know of, but
1002 they are not guaranteed, they're easy to remove, and removing them
1003 makes further changes easier.
1005 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
1006 This doesn't fix a bug but makes the code clearer.
1007 (string_overrun_cookie): Now const. Use initializers that
1008 don't formally overflow signed char, to avoid warnings.
1009 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
1010 can cause Emacs to crash when string overrun checking is enabled.
1011 (allocate_buffer): Don't assume sizeof (struct buffer) is a
1012 multiple of sizeof (EMACS_INT); it need not be, if
1013 alignof(EMACS_INT) < sizeof (EMACS_INT).
1014 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
1016 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

1045 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
1046 "cast to pointer from integer of different size".
1048 Improve doprnt and its use in verror. (Bug#8545)

1050 supported by the function. Use SAFE_ALLOCA instead of always
1053 * eval.c (verror): Don't limit the buffer size at size_max-1, that
1054 is one byte too soon. Don't use xrealloc; instead xfree and

1167 about invalid control letter, pass the character's codepoint, not
1168 a pointer to its multibyte form. Improve display of the character
1169 in octal and display also its hex code.
1171 * character.c (char_string): Use %x to display the (unsigned)
1172 codepoint of an invalid character, to avoid displaying a bogus
1175 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
1176 `error', not SYMBOL_NAME itself.
1178 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
1179 character arguments to `error'.
1181 * charset.c (check_iso_charset_parameter): Fix incorrect argument
1182 to `error' in error message about FINAL_CHAR argument. Make sure
1183 FINAL_CHAR is a character, and use %c when it is passed as
1184 argument to `error'.
1186 2011-04-23 Eli Zaretskii <eliz@gnu.org>
1188 * s/ms-w32.h (localtime): Redirect to sys_localtime.

1248 Define only if needed.
1250 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

1373 * nsfont.m: Fixed bugs in ns_get_family and
1374 ns_descriptor_to_entity that were caused by using free to
1375 deallocate memory blocks that were allocated by xmalloc (via
1376 xstrdup). This caused Emacs to crash when compiled with
1377 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
1378 --enable-checking=xmallocoverrun). xfree is now used to
1379 deallocate these memory blocks.

1394 Emacs source code has been audited now.
1395 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
1396 (emacs_read, emacs_write): Use it.
1397 * process.c (send_process): Adjust to the new signatures of
1398 emacs_write and emacs_gnutls_write. Do not attempt to store
1399 a byte offset into an 'int'; it might overflow.
1400 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html
1402 * sound.c: Don't assume sizes fit in 'int'.

1867 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
1868 since callers should never pass a negative size.
1869 Change the signature to match that of plain 'read' and 'write'; see
1870 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
1871 * lisp.h: Update prototypes of emacs_write and emacs_read.
1873 2011-04-11 Eli Zaretskii <eliz@gnu.org>
1875 * xdisp.c (redisplay_window): Don't try to determine the character
1876 position of the scroll margin if the window start point w->startp
1877 is outside the buffer's accessible region. (Bug#8468)
1879 2011-04-10 Eli Zaretskii <eliz@gnu.org>
1881 Fix write-region and its subroutines for buffers > 2GB.
1882 * fileio.c (a_write, e_write): Modify declaration of arguments and
1883 local variables to support buffers larger than 2GB.
1884 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
1886 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
1887 argument, local variables, and return value.
1889 * lisp.h: Update prototypes of emacs_write and emacs_read.
1891 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
1893 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
1895 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
1897 Fix more problems found by GCC 4.6.0's static checks.
1899 * xdisp.c (vmessage): Use a better test for character truncation.
1901 * charset.c (load_charset_map): <, not <=, for optimization,
1902 and to avoid potential problems with integer overflow.
1903 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
1904 * casetab.c (set_identity, shuffle): Likewise.
1905 * editfns.c (Fformat): Likewise.
1906 * syntax.c (skip_chars): Likewise.
1908 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
1909 This also lets GCC 4.6.0 generate slightly better loop code.
1911 * callint.c (Fcall_interactively): <, not <=, for optimization.
1912 (Fcall_interactively): Count the number of arguments produced,
1913 not the number of arguments given. This is simpler and lets GCC
1914 4.6.0 generate slightly better code.
1916 * ftfont.c: Distingish more carefully between FcChar8 and char.
1917 The previous code passed unsigned char * to a functions like
1918 strlen and xstrcasecmp that expect char *, which does not
1919 conform to the C standard.
1920 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
1921 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
1922 char * when the C standard requires it.
1924 * keyboard.c (read_char): Remove unused var.
1926 * eval.c: Port to Windows vsnprintf (Bug#8435).
1928 (SIZE_MAX): Define if the headers do not.
1929 (verror): Do not give up if vsnprintf returns a negative count.
1930 Instead, grow the buffer. This ports to Windows vsnprintf, which
1931 does not conform to C99. Problem reported by Eli Zaretskii.
1932 Also, simplify the allocation scheme, by avoiding the need for
1933 calling realloc, and removing the ALLOCATED variable.
1935 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
1937 Remove invocations of doprnt, as Emacs now uses vsnprintf.
1938 But keep the doprint source code for now, as we might revamp it
1939 and use it again (Bug#8435).
1940 * lisp.h (doprnt): Remove.
1941 * Makefile.in (base_obj): Remove doprnt.o.
1942 * deps.mk (doprnt.o): Remove.
1944 error: Print 32- and 64-bit integers portably (Bug#8435).
1945 Without this change, on typical 64-bit hosts error ("...%d...", N)
1946 was used to print both 32- and 64-bit integers N, which relied on
1948 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
1950 * lisp.h (error, verror): Mark as printf-like functions.
1951 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
1952 Report overflow in size calculations when allocating printf buffer.
1953 Do not truncate output string at its first null byte.
1954 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
1955 Truncate the output at a character boundary, since vsnprintf does not
1957 * charset.c (check_iso_charset_parameter): Convert internal
1958 character to string before calling 'error', since %c now has the
1960 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
1961 overflow when computing char to be passed to 'error'. Do not
1962 pass Lisp_Object to 'error'; pass the integer instead.
1963 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
1964 formatted with plain %d.
1966 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
1968 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
1970 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
1972 * xterm.c (x_catch_errors): Remove duplicate declaration.
1974 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
1976 * xdisp.c, lisp.h (message_nolog): Remove; unused.
1978 2011-04-10 Jim Meyering <meyering@redhat.com>
1980 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
1981 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
1982 return ssize_t not "int", and use size_t as the buffer length.
1983 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
1984 * gnutls.h: Update declarations.
1985 * process.c (read_process_output): Use ssize_t, to match.
1986 (send_process): Likewise.
1988 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
1990 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
1992 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
1994 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
1995 Use unsigned char, to match FcChar8 type definition.
1997 * xterm.c (handle_one_xevent):
1998 * xmenu.c (create_and_show_popup_menu):
1999 * xselect.c (x_decline_selection_request)
2000 (x_reply_selection_request): Avoid type-punned deref of X events.
2002 2011-04-09 Eli Zaretskii <eliz@gnu.org>
2004 Fix some uses of `int' instead of EMACS_INT.
2005 * search.c (string_match_1, fast_string_match)
2006 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
2007 (scan_buffer, find_next_newline_no_quit)
2008 (find_before_next_newline, search_command, Freplace_match)
2009 (Fmatch_data): Make some `int' variables be EMACS_INT.
2011 * xdisp.c (display_count_lines): 3rd argument and return value now
2012 EMACS_INT. All callers changed.
2013 (pint2hrstr): Last argument is now EMACS_INT.
2015 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
2016 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
2017 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
2018 (decode_coding_utf_16, decode_coding_emacs_mule)
2019 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
2020 (decode_coding_ccl, decode_coding_charset)
2021 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
2022 (decode_coding_iso_2022, decode_coding_emacs_mule)
2023 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
2024 <char_offset, last_offset>: Declare EMACS_INT.
2025 (encode_coding_utf_8, encode_coding_utf_16)
2026 (encode_coding_emacs_mule, encode_invocation_designation)
2027 (encode_designation_at_bol, encode_coding_iso_2022)
2028 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
2029 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
2031 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
2032 (encode_invocation_designation): Last argument P_NCHARS is now
2034 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
2035 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
2037 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
2040 * ccl.c (Fccl_execute_on_string): Declare some variables
2043 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
2045 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
2047 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>

2051 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
2053 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
2055 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
2057 * keyboard.c (read_char): Call Lisp function help-form-show,
2058 instead of using internal_with_output_to_temp_buffer.
2059 (Qhelp_form_show): New var.
2060 (syms_of_keyboard): Use DEFSYM macro.
2062 * print.c (internal_with_output_to_temp_buffer): Function deleted.
2064 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
2066 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
2068 * process.c (Flist_processes): Remove to Lisp.
2069 (list_processes_1): Delete.

2073 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
2075 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
2077 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
2079 Fix more problems found by GCC 4.6.0's static checks.
2081 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
2083 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
2085 * lisp.h (message, message_nolog, fatal): Mark as printf-like.

2095 (tiff_load): Add casts to remove these marks before passing them
2096 to system-supplied API.
2098 * eval.c (Fsignal): Remove excess argument to 'fatal'.
2100 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
2101 This avoids several warnings with gcc -Wstrict-overflow.
2102 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
2103 directly, rather than having caller test rule sign. This avoids
2104 some unnecessary tests.
2105 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
2106 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
2107 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
2109 * xfont.c (xfont_text_extents): Remove var that was set but not used.
2110 (xfont_open): Avoid unnecessary tests.
2112 * composite.c (composition_gstring_put_cache): Use unsigned integer.

2121 by using the new macro.
2123 * textprop.c (set_text_properties_1): Change while to do-while,
2124 since the condition is always true at first.

2151 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
2152 (font_score): Avoid potential overflow in diff calculation.
2154 * fns.c (substring_both): Remove var that is set but not used.
2155 (sxhash): Redo loop for clarity and to avoid wraparound warning.
2157 * eval.c (funcall_lambda): Rename local to avoid shadowing.
2159 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
2160 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
2161 can always succeed if overflow has undefined behavior.
2163 * search.c (boyer_moore, wordify): Remove vars set but not used.
2164 (wordify): Omit three unnecessary tests.
2166 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
2167 All callers changed. This avoids the need for an unused var.
2169 * casefiddle.c (casify_region): Remove var that is set but not used.
2171 * dired.c (file_name_completion): Remove var that is set but not used.
2173 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
2175 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
2176 (Finsert_file_contents): Remove unnecessary code checking fd.
2178 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
2179 Check for integer overflow on size calculations.
2181 * buffer.c (Fprevious_overlay_change): Remove var that is set
2184 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
2185 Remove vars that are set but not used.

2187 (timer_check_2): Mark vars as initialized.
2189 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
2191 * image.c (lookup_image): Remove var that is set but not used.
2192 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
2194 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
2195 that are set but not used.
2197 * xfns.c (make_invisible_cursor): Don't return garbage
2198 if XCreateBitmapFromData fails (Bug#8410).

2218 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
2219 All callers changed.
2220 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

2224 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
2225 that is set but not used.
2227 * print.c (print_object): Remove var that is set but not used.
2229 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
2230 The gnulib version avoids calling malloc in the usual case,
2231 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
2232 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
2233 * filelock.c (current_lock_owner): Likewise.
2234 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

2248 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
2249 if not defined (Bug#8403).
2251 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
2253 * xdisp.c (display_count_lines): Remove parameter `start',

2346 position point in the window according to scroll-conservatively,
2347 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
2349 (try_scrolling): When point is above the window, allow searching
2350 as far as scroll_max, or one screenful, to compute vertical
2351 distance from PT to the scroll margin position. This prevents
2352 try_scrolling from unnecessarily failing when
2353 scroll-conservatively is set to a value slightly larger than the
2354 window height. Clean up the case of PT below the margin at bottom
2355 of window: scroll_max can no longer be INT_MAX. When aggressive
2356 scrolling is in use, don't let point enter the opposite scroll
2357 margin as result of the scroll.
2358 (syms_of_xdisp) <scroll-conservatively>: Document the
2359 threshold of 100 lines for never-recentering scrolling.
2361 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
2363 * dispextern.h (move_it_by_lines):
2364 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
2365 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
2366 (message_log_check_duplicate): Remove parameters `prev_bol' and
2367 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
2368 (redisplay_internal): Remove parameter `preserve_echo_area',
2369 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
2371 * indent.c (Fvertical_motion):
2372 * window.c (window_scroll_pixel_based, Frecenter):
2373 Don't pass `need_y_p' to `move_it_by_lines'.
2375 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
2377 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
2378 steal a few bits to be more compact.
2379 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
2380 Remove unneeded casts.
2382 * bytecode.c (Fbyte_code): CAR and CDR can GC.
2384 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
2386 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
2387 binding" message (bug#7967).
2389 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
2391 Fix more problems found by GCC 4.6.0's static checks.
2393 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
2394 Remove unused local var.
2396 * editfns.c (Fmessage_box): Remove unused local var.
2398 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
2399 (note_mode_line_or_margin_highlight, note_mouse_highlight):
2400 Omit unused local vars.
2401 * window.c (shrink_windows): Omit unused local var.
2402 * menu.c (digest_single_submenu): Omit unused local var.
2403 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
2404 Omit unused local var.
2406 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
2407 Don't assume string length fits in int.
2408 (keyremap_step, read_key_sequence): Use size_t for sizes.
2409 (read_key_sequence): Don't check last_real_key_start redundantly.
2411 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
2412 instead of alloca (Bug#8344).
2414 * eval.c (Fbacktrace): Don't assume nargs fits in int.
2415 (Fbacktrace_frame): Don't assume nframes fits in int.
2417 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
2419 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
2422 * term.c (produce_glyphless_glyph): Remove unnecessary test.
2424 * cm.c (calccost): Turn while-do into do-while, for clarity.
2426 * keyboard.c (syms_of_keyboard): Use the same style as later
2427 in this function when indexing through an array. This also
2428 works around GCC bug 48267.
2430 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
2432 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
2434 * chartab.c (sub_char_table_ref_and_range): Redo for slight
2435 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
2437 * keyboard.c, keyboard.h (num_input_events): Now size_t.
2438 This avoids undefined behavior on integer overflow, and is a bit
2439 more convenient anyway since it is compared to a size_t variable.
2441 Variadic C functions now count arguments with size_t, not int.
2442 This avoids an unnecessary limitation on 64-bit machines, which
2443 caused (substring ...) to crash on large vectors (Bug#8344).
2444 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
2445 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
2446 All variadic functions and their callers changed accordingly.
2447 (struct gcpro.nvars): Now size_t, not int. All uses changed.
2448 * data.c (arith_driver, float_arith_driver): Likewise.
2449 * editfns.c (general_insert_function): Likewise.
2450 * eval.c (struct backtrace.nargs, interactive_p)
2451 (internal_condition_case_n, run_hook_with_args, apply_lambda)
2452 (funcall_lambda, mark_backtrace): Likewise.
2453 * fns.c (concat): Likewise.
2454 * frame.c (x_set_frame_parameters): Likewise.
2455 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
2456 0 if not found, not -1. All callers changed.
2458 * alloc.c (garbage_collect): Don't assume stack size fits in int.
2459 (stack_copy_size): Now size_t, not int.
2460 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
2462 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
2464 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
2465 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
2466 All callers changed.
2468 * lisp.h (multibyte_char_to_unibyte):
2469 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
2470 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
2471 * character.h (CHAR_TO_BYTE8):
2472 * cmds.c (internal_self_insert):
2473 * editfns.c (general_insert_function):
2474 * keymap.c (push_key_description):
2475 * search.c (Freplace_match):
2476 * xdisp.c (message_dolog, set_message_1): All callers changed.
2478 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
2480 * keyboard.c (safe_run_hook_funcall): New function.
2481 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
2482 don't set the hook to nil, but remove the offending function instead.
2483 (Qcommand_hook_internal): Remove, unused.
2484 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
2485 Vcommand_hook_internal.
2487 * eval.c (enum run_hooks_condition): Remove.
2488 (funcall_nil, funcall_not): New functions.
2489 (run_hook_with_args): Call each function through a `funcall' argument.
2490 Remove `cond' argument, now redundant.
2491 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)

2499 * print.c (strout): Remove parameter `multibyte', unused since
2500 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
2502 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
2503 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
2504 All callers changed.
2506 * w32.c (_wsa_errlist): Use braces for struct initializers.
2508 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
2509 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
2510 All callers changed.
2511 (string_buffer_position): Likewise. Also, make static (it's never
2512 used outside xdisp.c).
2513 (cursor_row_p): Remove parameter `w', unused since
2514 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
2515 (decode_mode_spec): Remove parameter `precision', introduced during
2516 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
2517 All callers changed.

2536 * nsmenu.m (runDialogAt): Remove argument to timer_check.
2538 2011-03-27 Glenn Morris <rgm@gnu.org>
2540 * syssignal.h: Replace RETSIGTYPE with void.
2541 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
2542 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
2543 Replace SIGTYPE with void everywhere.

2550 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
2552 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
2554 * w32.c (read_unc_volume): Use parameter `henum', instead of
2555 global variable `wget_enum_handle'.

2569 * w32menu.c (w32_menu_display_help):
2570 * xmenu.c (show_help_event, menu_help_callback):

2580 (gap_left, gap_right): Don't call it.
2582 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
2584 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
2585 incurred during fontification.
2587 2011-03-25 Juanma Barranquero <lekktu@gmail.com>

2653 2011-03-23 Julien Danjou <julien@danjou.info>
2655 * term.c (Fsuspend_tty, Fresume_tty):
2656 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
2657 * window.c (temp_output_buffer_show):
2658 * insdel.c (signal_before_change):

2665 * buffer.c (Fkill_all_local_variables):
2666 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
2668 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
2669 unconditionnaly since it does the check itself.
2671 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
2673 Fix more problems found by GCC 4.5.2's static checks.
2675 * coding.c (encode_coding_raw_text): Avoid unnecessary test
2676 the first time through the loop, since we know p0 < p1 then.
2677 This also avoids a gcc -Wstrict-overflow warning.
2679 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
2680 leading to a memory leak, possible in functions like
2681 load_charset_map_from_file that can allocate an unbounded number
2682 of objects (Bug#8318).
2684 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
2685 that could (at least in theory) be that large.
2687 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
2688 This is less likely to overflow, and avoids undefined behavior if
2689 overflow does occur. All callers changed. Use strtoul to scan
2690 for the unsigned long integer.
2691 (pint2hrstr): Simplify and tune code slightly.
2692 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
2694 * scroll.c (do_scrolling): Work around GCC bug 48228.
2695 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

2698 This also avoids a warning with gcc -Wstrict-overflow.
2699 (validate_x_resource_name): Simplify count usage.
2700 This also avoids a warning with gcc -Wstrict-overflow.
2702 * fileio.c (Fcopy_file): Report error if fchown or fchmod
2705 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
2707 * process.c (Fmake_network_process): Use socklen_t, not int,
2708 where POSIX says socklen_t is required in portable programs.
2709 This fixes a porting bug on hosts like 64-bit HP-UX, where
2710 socklen_t is wider than int (Bug#8277).
2711 (Fmake_network_process, server_accept_connection):
2712 (wait_reading_process_output, read_process_output):
2715 * process.c: Rename or move locals to avoid shadowing.

2717 (read_process_output_error_handler, exec_sentinel_error_handler):
2718 Rename or move locals.
2719 (Fmake_network_process): Define label "retry_connect" only if needed.

2721 (process_send_signal): Add cast to avoid pointer signedness problem.
2722 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
2723 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
2725 Make tparam.h and terminfo.c consistent.
2726 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
2727 Include tparam.h instead, since it declares them.
2728 * cm.h (PC): Remove extern decl; tparam.h now does this.
2729 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
2730 * terminfo.c: Include tparam.h, to check interfaces.
2731 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
2732 (tparam): Adjust signature to match interface in tparam.h;
2733 this removes some undefined behavior. Check that outstring and len
2734 are zero, which they always are with Emacs.
2735 * tparam.h (PC, BC, UP): New extern decls.
2737 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
2738 (xftfont_open): Rename locals to avoid shadowing.
2740 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
2741 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
2742 (OTF_TAG_SYM): Omit macro if not needed.
2743 (ftfont_list): Remove unused local.
2744 (get_adstyle_property, ftfont_pattern_entity):
2745 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
2746 Rename locals to avoid shadowing.
2748 * xfont.c (xfont_list_family): Mark var as initialized.
2750 * xml.c (make_dom): Now static.
2752 * composite.c (composition_compute_stop_pos): Rename local to
2754 (composition_reseat_it): Remove unused locals.
2755 (find_automatic_composition, composition_adjust_point): Likewise.
2756 (composition_update_it): Mark var as initialized.
2757 (find_automatic_composition): Mark vars as initialized,
2758 with a FIXME (Bug#8290).
2760 character.h: Rename locals to avoid shadowing.
2761 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
2762 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
2763 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
2764 (BUF_DEC_POS): Be more systematic about renaming local temporaries
2767 * textprop.c (property_change_between_p): Remove; unused.
2769 * intervals.c (interval_start_pos): Now static.
2771 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
2773 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
2774 Rename locals to avoid shadowing.
2776 * sound.c (wav_play, au_play, Fplay_sound_internal):
2777 Fix pointer signedness.
2778 (alsa_choose_format): Remove unused local var.
2779 (wav_play): Initialize a variable to 0, to prevent undefined
2780 behavior (Bug#8278).
2782 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
2784 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
2786 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
2787 clobbering (Bug#8298).
2788 * sysdep.c (sys_subshell): Likewise.
2789 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
2791 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
2792 This should get cleaned up, so that child_setup has the
2793 same signature on all platforms.
2795 * callproc.c (call_process_cleanup): Now static.
2796 (relocate_fd): Rename locals to avoid shadowing.
2798 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

2860 * deps.mk (unexalpha.o): Remove; unused.
2862 New file unexec.h, the (simple) interface for unexec (Bug#8267).

2888 instead of using an uninitialized var.
2889 (font_sort_entities): Mark var as initialized.

2965 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
2966 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
2967 to use the following functions instead of these macros.
2968 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
2969 EMACS_INT, since callers assume the returned value fits in int.
2970 (upcase1): Likewise, for UPCASE_TABLE.
2971 (uppercasep, lowercasep, upcase): New static inline functions.
2972 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

2982 (regex_compile, re_match_2_internal): Mark locals as initialized.
2983 (RETALLOC_IF): Define only if needed.
2984 (WORDCHAR_P): Likewise. This one is never needed, but is used
2985 only in a comment talking about a compiler bug, so put inside
2986 the #if 0 of that comment.
2987 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
2988 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
2991 * search.c (boyer_moore): Rename locals to avoid shadowing.

3014 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
3015 New macros, so that the caller can use some names other than
3016 gcpro1, gcpro2, etc.
3017 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
3019 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
3020 argument, for consistency with GCPRO2_VAR, etc: it is now the
3021 prefix of the variable, not the variable itself. All uses
3023 * dired.c (directory_files_internal, file_name_completion):
3024 Rename locals to avoid shadowing.
3026 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
3027 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
3028 dired.c's scmp function, had undefined behavior.
3029 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3030 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
3031 * buffer.h: ... to here, because these macros use current_buffer,
3032 and the new implementation with inline functions needs to have
3033 current_buffer in scope now, rather than later when the macros
3035 (downcase, upcase1): New static inline functions.
3036 (DOWNCASE, UPCASE1): Reimplement using these functions.
3037 This avoids undefined behavior in expressions like
3038 DOWNCASE (x) == DOWNCASE (y), which previously suffered
3039 from race conditions in accessing the global variables
3040 case_temp1 and case_temp2.
3041 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
3042 * lisp.h (case_temp1, case_temp2): Remove their decls.
3043 * character.h (ASCII_CHAR_P): Move from here ...
3044 * lisp.h: ... to here, so that the inline functions mentioned
3047 * dired.c (directory_files_internal_unwind): Now static.
3049 * fileio.c (file_name_as_directory, directory_file_name):
3050 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
3052 (file_name_as_directory): Use const pointers when appropriate.
3053 (Fexpand_file_name): Likewise. In particular, newdir might
3054 point at constant storage, so make it a const pointer.
3055 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
3056 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
3058 (Fset_file_times, Finsert_file_contents, auto_save_error):
3059 Rename locals to avoid shadowing.

3065 * marker.c (bytepos_to_charpos): Remove; unused.
3067 * lisp.h (verify_bytepos, count_markers): New decls,
3068 so that gcc does not warn that these functions aren't declared.
3070 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
3071 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
3072 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
3073 (copy_text): Remove unused local var.
3075 * filelock.c (within_one_second): Now static.
3076 (lock_file_1): Rename local to avoid shadowing.
3078 * buffer.c (fix_overlays_before): Mark locals as initialized.
3079 (fix_start_end_in_overlays): Likewise. This function should be
3080 simplified by using pointers-to-pointers, but that's a different
3082 (switch_to_buffer_1): Now static.
3083 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
3084 (report_overlay_modification): Rename locals to avoid shadowing.
3086 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
3087 Fix pointer signedness issue.
3088 (sys_subshell): Mark local as volatile if checking for lint,
3089 to suppress a gcc -Wclobbered warning that does not seem to be right.
3090 (MAXPATHLEN): Define only if needed.
3092 * process.c (serial_open, serial_configure): Move decls from here ...
3093 * systty.h: ... to here, so that they can be checked.
3095 * fns.c (get_random, seed_random): Move extern decls from here ...
3096 * lisp.h: ... to here, so that they can be checked.
3098 * sysdep.c (reset_io): Now static.
3099 (wait_for_termination_signal): Remove; unused.
3101 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

3108 Rename locals to avoid shadowing.
3110 * keyboard.c: Declare functions static if they are not used elsewhere.
3111 (echo_char, echo_dash, cmd_error, top_level_2):
3112 (poll_for_input, handle_async_input): Now static.
3113 (read_char, kbd_buffer_get_event, make_lispy_position):

3258 1152921504606846976) returns the obviously-bogus value (-948597
3259 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
3260 reports time overflow. See
3261 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
