1 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3 * character.c, charset.c, chartab.c: Use bool for booleans.
4 * character.c (lisp_string_width, string_count_byte8)
6 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7 (load_charset_map_from_file, map_charset_chars)
8 (Fdefine_charset_internal, define_charset_internal)
9 (Fdeclare_equiv_charset, find_charsets_in_text)
10 (Ffind_charset_region, char_charset, Fiso_charset):
11 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
12 (sub_char_table_set, sub_char_table_set_range)
13 (char_table_set_range, optimize_sub_char_table)
16 * character.c (str_to_unibyte): Omit last boolean argument; it was
17 always 0. All callers changed.
18 * character.h, charset.h: Adjust to match previous changes.
19 * character.h (char_printable_p): Remove decl of nonexistent function.
20 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
21 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
22 are all boolean, so make them single-bit bitfields.
24 * lisp.h (ASET): Remove attempt to detect side effects.
25 It was meant to be temporary and it often doesn't work,
26 because when IDX has side effects the behavior of IDX==IDX
27 is undefined. See Stefan Monnier in
28 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
30 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
32 * lisp.h (functionp): New function (extracted from Ffunctionp).
34 * eval.c (Ffunctionp): Use it.
36 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
38 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
39 as that's faster and simpler than static storage. Don't bother
40 with the g_main_context_query overhead if g_main_context_pending
41 says no events are pending.
42 (gfds, gfds_size): Remove these static vars.
43 (xgselect_initialize): Remove; no longer needed.
44 All uses and decls removed.
46 * emacs.c (fatal_error_signal_hook): Remove.
47 All uses removed. This leftover from old code was always 0.
49 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
50 * casefiddle.c (casify_object, casify_region):
51 * casetab.c (set_case_table):
52 * category.c, category.h (word_boundary_p):
53 * category.h (CHAR_HAS_CATEGORY):
54 Use bool for booleans, instead of int.
56 2012-08-25 Eli Zaretskii <eliz@gnu.org>
58 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
60 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
62 On assertion failure, print backtrace if available.
63 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
64 (die) [ENABLE_CHECKING]: Print a backtrace if available.
65 * Makefile.in (LIB_EXECINFO): New macro.
68 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
69 * bytecode.c (exec_byte_code):
70 * callint.c (check_mark, Fcall_interactively):
71 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
72 (getenv_internal, sync_process_alive, call_process_exited):
73 * lisp.h (USE_SAFE_ALLOCA):
74 Use bool for booleans, instead of int.
75 * lisp.h, process.h: Adjust prototypes to match above changes.
76 * callint.c (Fcall_interactively): Don't assume the mark's
79 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
81 * buffer.c, buffer.h: Use bool for boolean.
82 * buffer.c (reset_buffer_local_variables)
83 (buffer_lisp_local_variables, Fset_buffer_modified_p)
84 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
85 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
86 (overlay_touches_p, overlay_strings, Foverlay_put)
87 (report_overlay_modification, call_overlay_mod_hooks):
88 (mmap_enlarge, mmap_set_vars):
89 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
90 Use bool for booleans, instead of int.
91 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
92 since the 1-or-0 return value is always ignored anyway.
94 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
95 * buffer.h, lisp.h: Adjust prototypes to match above changes.
97 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
99 * bidi.c: Use bool for boolean.
100 This is a bit more readable, and makes the text segment of bidi.o
101 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
102 Presumably it's faster too.
103 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
105 (bidi_cache_find_level_change, bidi_cache_iterator_state)
106 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
107 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
108 (bidi_explicit_dir_char, bidi_level_of_next_char)
109 (bidi_find_other_level_edge, bidi_move_to_visually_next):
110 Use bool for booleans, instead of int.
111 * dispextern.h (bidi_init_it, bidi_paragraph_init)
112 (bidi_unshelve_cache): Adjust decls to match code.
114 2012-08-23 Martin Rudalics <rudalics@gmx.at>
116 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
119 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
121 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
122 * atimer.h: Include <stdbool.h>.
124 2012-08-22 Dan Nicolaescu <dann@gnu.org>
126 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
127 compile time tests instead of run time tests on systems that do
129 (FRAME_MAC_P): Remove leftover from deleted code.
130 * frame.c (syms_of_frame): Remove leftover from deleted code.
132 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
134 * nsterm.m (insertText:): Don't clear modifiers if code is space.
136 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
138 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
139 Otherwise, the compiler complains about (A?B:C) where B is void
140 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
141 (fontset_add): Return void, for FONTSET_ADD.
143 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
145 * alloc.c: Use bool for booleans.
146 (gc_in_progress, abort_on_gc)
147 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
148 (dont_register_blocks) [GC_MALLOC_CHECK]:
149 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
150 (check_string_bytes, make_specified_string, memory_full)
151 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
152 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
153 (mark_stack, valid_pointer_p, make_pure_string)
154 (Fgarbage_collect, survives_gc_p, gc_sweep):
155 Use bool for booleans, instead of int.
156 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
158 * alloc.c (PURE_POINTER_P):
159 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
160 * editfns.c (Fformat):
161 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
163 * fns.c (sweep_weak_table):
164 * lisp.h (suppress_checking, push_message, survives_gc_p)
165 (make_pure_string, gc_in_progress, abort_on_gc):
166 * lread.c (readchar, read1):
167 * print.c (Fprin1_to_string):
168 * xdisp.c (push_message):
169 Use bool for booleans affected directly or indirectly by
172 Make recently-introduced setters macros.
173 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
174 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
175 (set_fontset_default, set_fontset_fallback): Rename from their
176 upper-case counterparts, and make them functions rather than macros.
177 This is more consistent with the other recently-introduced setters.
178 These don't need to be inline, since they're local.
180 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
182 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
183 the loop (Bug#12247).
185 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
187 * lisp.h (vcopy): Use memcpy rather than our own loop.
188 This fixes a performance regression introduced by the recent
189 addition of vcopy. This means 'vcopy' will need to be modified
190 for a copying collector, but that's OK. Also, tighten the
191 checking in the assertion.
193 2012-08-21 Eli Zaretskii <eliz@gnu.org>
195 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
196 components for RTL text (Bug#11860). Adjust X-OFFSET of each
197 non-base glyph for the width of the base character, according to
198 what x_draw_composite_glyph_string_foreground expects.
199 Generate WADJUST value according to composition_gstring_width's
200 expectations, to produce correct width of the composed character.
201 Reverse the sign of the DU offset produced by ScriptPlace.
203 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
205 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
207 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
209 Avoid direct writes to contents member of struct Lisp_Vector.
210 * lisp.h (vcopy): New function to copy data into vector.
211 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
212 * fns.c (Ffillarray): Use ASET.
213 * keyboard.c (timer_check_2): Use AREF and ASET.
214 (append_tool_bar_item, Frecent_keys): Use vcopy.
215 * lread.c (read_vector): Use ASET.
216 * msdos.c (Frecent_doskeys): Use vcopy.
217 * xface.c (Finternal_copy_lisp_face): Use vcopy.
218 (Finternal_merge_in_global_face): Use ASET and vcopy.
219 * xfont.c (xfont_list_pattern): Likewise.
221 2012-08-21 Martin Rudalics <rudalics@gmx.at>
223 * window.c (Fwindow_point): For the selected window always return
224 the position of its buffer's point.
225 (Fset_window_point): For the selected window always go in its
226 buffer to the specified position.
228 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
230 Setter macros for fontsets.
231 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
232 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
233 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
236 2012-08-20 Glenn Morris <rgm@gnu.org>
238 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
239 Don't assume that `ln -f' works.
241 2012-08-20 Eli Zaretskii <eliz@gnu.org>
243 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
244 and later about non-assignments with no effect. See discussion at
245 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
248 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
250 Inline setter functions for Lisp_Objects slots of struct specbinding.
251 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
254 2012-08-20 Martin Rudalics <rudalics@gmx.at>
256 * window.c (select_window): Always make selected window's buffer
259 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
261 Use AREF and ASET for docstrings of category tables.
262 * category.h (CATEGORY_DOCSTRING): Use AREF.
263 (SET_CATEGORY_DOCSTRING): Use ASET.
264 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
266 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
268 Inline setter functions for hash table members.
269 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
270 (set_hash_hash, set_hash_index): Rename with _slot suffix.
271 (set_hash_key_and_value, set_hash_index, set_hash_next)
272 (set_hash_hash): New functions.
273 * charset.c, fns.c: Adjust users.
275 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
277 Inline getter and setter functions for per-buffer values.
278 * buffer.h (per_buffer_default, set_per_buffer_default)
279 (per_buffer_value, set_per_buffer_value): New functions.
280 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
281 * buffer.c, data.c: Adjust users.
283 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
285 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
287 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
289 Rely on <config.h> + <unistd.h> to declare 'environ',
290 as gnulib does this if the system doesn't.
291 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
292 Remove declaration. MS-Windows declares it on stdlib.h which is
293 included by conf_post.h.
294 * emacs.c (environ) [DOUG_LEA_MALLOC]:
295 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
296 * vm-limit.c: Include <unistd.h>, for 'environ'.
298 * unexaix.c, unexcoff.c: Include "mem-limits.h".
299 (start_of_data): Remove decl; mem-limits.h provides it.
301 * xdisp.c (handle_invisible_prop): Make it a bit faster
302 and avoid a gcc -Wmaybe-uninitialized diagnostic.
304 2012-08-19 Chong Yidong <cyd@gnu.org>
306 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
309 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
311 * .gdbinit: Use call instead of set when calling a function in the
314 * data.c (set_internal): Don't use set_blv_found.
315 (Fkill_local_variable): Likewise.
317 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
319 * nsfont.m (ns_ascii_average_width): Ensure the string
320 ascii_printable is initialized with a null-terminated character
321 array. Otherwise, it can contain undesired extra characters.
323 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
325 port new setting code to Sun C 5.8 2005/10/13
326 * chartab.c, lisp.h (char_table_set, char_table_set_range):
327 Return void, not Lisp_Object. Otherwise, the compiler
328 complains about (A?B:C) where B is void and C is Lisp_Object
329 when compiling CHAR_TABLE_SET, due to the recent change to
330 the API of sub_char_table_set_contents.
332 2012-08-18 Chong Yidong <cyd@gnu.org>
334 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

1163 * w32.c (init_environment): Change the default values of many
1164 environment variables in dflt_envvars[] to NULL, to avoid pushing
1165 them into environment when they were not already defined.
1166 Remove the code that deletes site-lisp subdirectories from the default
1167 value of EMACSLOADPATH, as it is no longer needed.
1168 (check_windows_init_file): Now external, not static.
1169 Use Vload_path as is, without adding anything, as this function is now
1170 called when Vload_path is already set up.
1172 * w32.h (check_windows_init_file): Add prototype.
1174 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

1217 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
1218 Remove unnecessary pointer casts.
1219 * alloc.c (record_xmalloc): New function.
1220 * lisp.h (record_xmalloc): New decl.
1221 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
1222 more like a function. This is because the pointer cast is not
1223 needed. All uses changed.
1224 * print.c (print_string, print_error_message): Avoid length recalc.
1226 Improve fix for macroexp crash with debugging (Bug#12118).
1227 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
1228 ARRAY_MARK_FLAG when checking subscripts, because ASET is

1261 with addition of handling of symlinks and support for 'lstat'.
1262 If possible, get file's attributes and security information by
1263 handle, not by name. Produce S_IFLNK bit for symlinks, when
1264 called from 'lstat'.
1265 (stat, lstat): New functions, call 'stat_worker'.
1266 (symlink, readlink, careadlinkat): Rewritten to create and resolve
1267 symlinks when the underlying filesystem supports them.
1269 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
1271 Fix macroexp crash on Windows with debugging (Bug#12118).
1272 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
1273 checking subscripts; problem introduced with the recent
1274 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
1275 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
1276 since it's used in non-static inline functions now.
1278 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
1279 Don't assume buffer size fits in 'int'. Remove unused local.

1300 * dispnew.c (DISPEXTERN_INLINE):
1301 * sysdep.c (SYSTIME_INLINE):

1305 (INLINE_HEADER_END): New macros.
1306 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

1326 hard-coding the path separator.
1328 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
1330 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
1331 This how ASET and AREF are supposed to work, and makes
1332 it easier to think about future improvements. See
1333 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
1334 * charset.h (set_charset_attr): New function.

1818 Reimplement to use struct Lisp_Excursion. Add comments.
1820 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
1822 Fix export of symbols to GDB (Bug#12036).
1823 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
1824 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
1825 emacs.c, as this is a more-suitable home. Had this been done earlier
1826 the fix for 12036 would have avoided some of the problems noted in
1827 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1828 would have been more obvious.
1829 * emacs.c: Do not include <verify.h>; no longer needed.
1830 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
1831 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
1832 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1833 Remove; now done in lisp.h.
1834 * lisp.h (PUBLISH_TO_GDB): New macro.
1835 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
1836 (DATA_SEG_BITS): Use it.
1837 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
1838 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1839 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1840 not be usable in #if. This simplifies things.
1842 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1844 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
1846 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

1849 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1850 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1851 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1852 Adjust to changes in lisp.h and emacs.c, by using
1853 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1854 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1855 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1856 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1857 instead of gdb_valbits.
1858 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1859 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1860 instead of gdb_array_mark_flag.
1861 (xboolvector): Get size from $->size, not $->header.size.
1862 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1863 (xreload, hook-run, hookpost-run): Remove.
1864 * emacs.c: Include <verify.h>.
1865 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1866 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1868 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1869 (gdb_USE_LSB_TAG): New enum constants.
1870 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1871 Also define these as enum constants, so they're visible to GDB.
1872 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1873 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1874 as constants, so they're visible to GDB.
1875 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
1876 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
1877 Now enum constants, not macros, so they're visible to GDB.
1878 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1879 more convenient now. All uses changed.
1880 (VALMASK) [USE_LSB_TAG]: Also define in this case.
1881 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
1883 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
1885 Explicitly free restriction data that are not needed anymore.

1888 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
1890 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
1891 add argument, tune behavior, and adjust all callers.
1893 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1895 Use typedef for EMACS_INT, EMACS_UINT.
1896 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1897 than macros. This simplifies debugging in the usual case, since
1898 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1899 and it allows expressions involving EMACS_INT casts.
1900 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1902 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

1912 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
1914 Adjust buffer text indirection counters at the end of Fkill_buffer.
1915 * buffer.c (Fkill_buffer): Adjust indirection counters when the
1916 buffer is definitely dead. This should really fix an issue reported
1917 by Christoph Scholtes again. (Bug#12007).
1918 (init_buffer_once): Initialize indirection counters of
1919 buffer_defaults and buffer_local_symbols (for sanity and safety).
1921 2012-07-24 Eli Zaretskii <eliz@gnu.org>
1923 * xdisp.c (init_iterator): Don't compute dimensions of truncation
1924 and continuation glyphs on tooltip frames, leave them at zero.

1936 or invalid. (Bug#12025)
1938 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
1939 it signals an error when a tooltip frame is being created.

1950 (build_overlay): Add prototype.
1952 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1954 Swap buffer text indirection counters in Fbuffer_swap_text.
1955 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1956 This avoids crash reported by Christoph Scholtes at
1957 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1959 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1961 * nsmenu.m (Popdown_data): New struct.

1966 and autorelease them. Also autorelease img and matrix (Bug#12005).

1984 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
1986 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
1987 as it's limited by the amount of memory, not by INT_MAX.
1989 2012-07-21 Eli Zaretskii <eliz@gnu.org>
1991 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

2142 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
2144 * eval.c (Fdefvar): Don't check constants since we only set the var if
2145 it's not yet defined anyway (bug#11904).
2147 * lisp.h (last_undo_boundary): Declare new var.
2148 * keyboard.c (command_loop_1): Set it.
2149 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
2150 were auto-added by the command loop (bug#11774).

2718 This replaces macros (which typically do not work in GDB)
2719 with functions, typedefs and enums, making the code easier to debug.
2720 The functional style also makes code easier to read and maintain.
2721 * systime.h: Include <sys/time.h> on all hosts, not just if
2722 WINDOWSNT, since 'struct timeval' is needed in general.
2723 (EMACS_TIME): Now a typedef, not a macro.
2724 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
2726 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
2727 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
2728 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
2729 (EMACS_TIME_LE): Now functions, not macros.
2730 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
2731 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
2732 which are not functions. All uses rewritten to use:
2733 (make_emacs_time): New function.
2734 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
2735 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
2736 not functions. All uses rewritten to use the following, respectively:
2737 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
2738 (add_emacs_time, sub_emacs_time): New functions.
2739 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
2740 * fileio.c (Fcopy_file):
2741 * xterm.c (XTflash): Get the current time closer to when it's used.
2742 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
2744 * bytecode.c (targets): Suppress -Woverride-init warnings.
2746 Simplify by avoiding confusing use of strncpy etc.
2747 * doc.c (Fsnarf_documentation):
2748 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
2749 * frame.c (Fmake_terminal_frame):
2750 * gtkutil.c (get_utf8_string):
2752 * nsmenu.m (ns_update_menubar):
2753 * regex.c (regerror):
2754 Prefer memcpy to strncpy and strncat when either will do.
2755 * fileio.c (Fsubstitute_in_file_name):
2756 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
2757 (menu_separator_name_p):
2758 * nsmenu.m (ns_update_menubar):
2759 Prefer memcmp to strncmp when either will do.
2760 * nsterm.m: Include <ftoastr.h>.
2762 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
2763 Prefer snprintf to strncpy.
2764 * nsterm.m (ns_term_init):
2765 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2766 * nsterm.m (ns_term_init):
2767 Avoid the need for strncpy, by using build_string or
2768 make_unibyte_string directly. Use dtoastr, not snprintf.
2769 * process.c (Fmake_network_process): Diagnose service names that
2770 are too long, rather than silently truncating them or creating
2771 non-null-terminated names.
2772 (Fnetwork_interface_info): Likewise, for interface names.
2773 * sysdep.c (system_process_attributes) [GNU_LINUX]:
2774 Prefer sprintf to strncat.
2775 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
2776 Prefer vsnprintf to vsprintf + strncpy.
2778 2012-07-10 Glenn Morris <rgm@gnu.org>
2780 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
2781 Clarify fallback case.
2783 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2785 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
2786 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
2787 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
2788 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
2789 where argument type is known to be a Lisp_Cons.
2791 2012-07-10 Tom Tromey <tromey@redhat.com>
2793 * bytecode.c (BYTE_CODE_THREADED): New macro.
2794 (BYTE_CODES): New macro. Replaces all old byte-code defines.
2795 (enum byte_code_op): New type.
2796 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
2797 (exec_byte_code): Use them. Use token threading when applicable.
2799 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2801 Optimize pure C strings initialization.
2802 * lisp.h (make_pure_string): Fix prototype.
2803 (build_pure_c_string): New function, defined as static inline. This
2804 provides a better opportunity to optimize away calls to strlen when
2805 the function is called with compile-time constant argument.
2806 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2807 argument, adjust users accordingly. Use build_pure_c_string where
2809 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2810 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2811 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2813 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2815 Avoid calls to strlen in miscellaneous functions.
2816 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2817 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2818 * lread.c (openp): Likewise.
2820 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2822 Avoid calls to strlen in path processing functions.
2823 * fileio.c (file_name_as_directory): Add comment. Change to add
2824 srclen argument and return the length of result. Adjust users
2826 (directory_file_name): Fix comment. Change to add srclen argument,
2827 swap 1st and 2nd arguments to obey the common convention.
2828 Adjust users accordingly.
2829 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2831 2012-07-10 Glenn Morris <rgm@gnu.org>
2833 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
2834 Move PENDING_OUTPUT_COUNT definition to configure.
2836 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
2837 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
2838 * s/gnu.h (DATA_START): Move definitions to configure.
2840 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2841 We include usg5-4-common.h, which defines them both.
2843 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2844 O_RDONLY already includes it).
2846 Stop ns builds setting the EMACSLOADPATH environment variable.
2847 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2848 Now it does not set EMACSLOADPATH, just returns the load-path string.
2849 * nsterm.h: Update accordingly.
2850 * lread.c [HAVE_NS]: Include nsterm.h.
2851 (init_lread) [HAVE_NS]: Use ns_load_path.
2852 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
2854 2012-07-09 Glenn Morris <rgm@gnu.org>
2856 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2857 since the included bsd-common.h does so.
2859 Stop ns builds setting the EMACSPATH environment variable.
2860 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2861 (ns_init_paths): Do not set EMACSPATH.
2862 * nsterm.h (ns_exec_path): Add it.
2863 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2866 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2868 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2870 * process.c (wait_reading_process_output): 'waitchannels' was unset
2871 when read_kbd || !NILP (wait_for_cell); fix this.
2873 Add GCC-style 'const' attribute to functions that can use it.
2874 * character.h (char_resolve_modifier_mask):
2875 * keyboard.h (make_ctrl_char):
2876 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
2877 (init_character_once, next_almost_prime, init_fns, init_image)
2878 (flush_pending_output, init_sound):
2879 * mem-limits.h (start_of_data):
2880 * menu.h (finish_menu_items):
2881 Add ATTRIBUTE_CONST.

2883 Declare the dummy function with ATTRIBUTE_CONST.
2884 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2885 Add decls with ATTRIBUTE_CONST.
2887 Minor improvements to make_formatted_string.
2888 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2889 where int is good enough, as vsprintf returns an int.
2890 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2892 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2894 Use make_formatted_string to avoid double length calculation.
2895 * lisp.h (make_formatted_string): New prototype.
2896 * alloc.c (make_formatted_string): New function.
2897 * buffer.c (Fgenerate_new_buffer_name): Use it.
2898 * dbus.c (syms_of_dbusbind): Likewise.
2899 * editfns.c (Fcurrent_time_zone): Likewise.
2900 * filelock.c (get_boot_time): Likewise.
2901 * frame.c (make_terminal_frame, set_term_frame_name)
2902 (x_report_frame_params): Likewise.
2903 * image.c (gs_load): Likewise.
2904 * minibuf.c (get_minibuffer): Likewise.
2905 * msdos.c (dos_set_window_size): Likewise.
2906 * process.c (make_process): Likewise.

2910 2012-07-09 Glenn Morris <rgm@gnu.org>
2912 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
2913 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
2914 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

2917 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
2919 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2921 Move marker debugging code under MARKER_DEBUG.
2922 * marker.c (MARKER_DEBUG): Move marker debugging code under
2923 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2924 for bootstrap with --enable-checking (~3x slowdown reported
2925 by Juanma Barranquero <lekktu@gmail.com>).
2926 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2928 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2930 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2931 See <http://bugs.gnu.org/11825#29>.
2933 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2935 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2936 has no font, use the frame's font. (Bug#11813)
2937 (display_line): Add commentary about displaying truncation glyphs
2939 (produce_special_glyphs): Move here from term.c.
2941 * term.c (produce_special_glyphs): Move to xdisp.c.
2943 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2946 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2948 * xdisp.c (display_line): Avoid warning about implicit declaration
2951 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2953 * lisp.h: Remove empty conditional.
2955 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2957 * lread.c (load_path_check): Now static.
2959 Fix some minor --with-ns problems found by static checking.
2960 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2961 (x_set_font) [!HAVE_X_WINDOWS]:
2962 * image.c (xpm_load_image) [HAVE_NS]:
2963 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2964 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2965 Remove unused local.
2966 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2967 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2968 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2969 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2970 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2971 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2972 Fix pointer signedness problem.
2973 * xfaces.c (FRAME_X_FONT_TABLE):
2974 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2976 2012-07-07 Glenn Morris <rgm@gnu.org>
2978 * lread.c (load_path_check): New function, split from init_lread.
2979 (init_lread): Reorganize. Motivation:
2980 If EMACSLOADPATH is set, check/warn about that rather than the
2981 defaults, which we are not going to use. Hence we can remove
2982 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2983 Don't warn if site-lisp directories are missing.
2984 If not installed, start from a blank load-path, since
2985 PATH_LOADSEARCH refers to the eventual installation directories.
2987 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2989 Support truncation and continuation glyphs on GUI frames, when
2990 fringes are disabled. (Bug#11832)
2991 * xdisp.c (init_iterator): Get dimensions of truncation and
2992 continuation glyphs even if on GUI frames.
2993 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2994 or both, are absent.
2995 (start_display, move_it_in_display_line_to): Handle the case of a
2996 GUI frame without a fringe to display continuation or truncation
2998 (insert_left_trunc_glyphs): Support GUI frames: make sure
2999 truncation glyphs overwrite enough glyphs from the current line to
3000 have sufficient space in pixels.
3001 (display_line): Support truncation and continuation glyphs on GUI
3002 frames. If some spare pixels are left on the line after inserting
3003 the truncation glyphs, fill that space with a stretch glyph of a
3004 suitably computed width.
3006 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
3007 produce_glyphs, to support GUI sessions.
3009 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3011 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
3013 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
3015 Do not require float-time's arg to fit in time_t (Bug#11825).
3016 This works better on hosts where time_t is unsigned, and where
3017 float-time is applied to the (negative) difference between two times.
3018 * editfns.c (decode_time_components): Last arg is now double *,
3019 not int *, and means to store all the result as a double, without
3020 worrying about whether the seconds part fits in time_t.
3021 All callers changed.
3022 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
3023 All callers changed.
3024 (Ffloat_time): Do not fail merely because the specified time falls
3025 outside of time_t range.
3027 2012-07-07 Glenn Morris <rgm@gnu.org>
3029 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
3030 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
3031 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
3033 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
3035 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
3036 Update dependencies.
3038 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
3040 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3042 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
3043 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
3044 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3045 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
3046 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
3047 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
3049 * xfont.c (compare_font_names): Redo to omit the need for casts.
3051 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
3053 * xfns.c (Fx_change_window_property): Doc fix.
3054 * w32fns.c (Fx_change_window_property): Doc fix.
3056 * w32fns.c (Fx_window_property): Accept the same arguments as the
3057 X Windows version. Doc fix.
3058 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3060 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3061 Eli Zaretskii <eliz@gnu.org>
3063 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
3064 Windows-specific code from nt/config.nt moved here.
3065 Obsolete settings removed.
3067 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3069 * process.c: Avoid unnecessary calls to gettime.
3070 (wait_reading_process_output): Don't get the time of day
3071 when gobbling data immediately and not waiting, as there's no need
3072 for it in that case. This removes a FIXME.
3074 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
3076 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
3077 is defined (Bug#11768).
3079 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3081 Fix marker debugging code.
3082 * marker.c (byte_char_debug_check): Do not perform the check
3083 if buffer is not multibyte.
3084 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3085 Call byte_char_debug_check with correct arguments.
3087 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3089 Compile marker debugging code only if ENABLE_CHECKING is defined.
3090 * marker.c (byte_char_debug_check, count_markers):
3091 Use only if ENABLE_CHECKING is defined.
3092 (byte_debug_flag): Remove.
3093 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3094 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
3096 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3098 Avoid code repetition in marker-related functions.
3099 * marker.c (attach_marker): New function.
3100 (Fset_marker, set_marker_restricted, set_marker_both)
3101 (set_marker_restricted_both): Use it.
3102 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
3103 Consistently rename charno to charpos.
3104 (marker_position): Add eassert.
3105 (marker_byte_position): Convert to eassert.
3107 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3109 Simplify list operations in unchain_overlay and unchain_marker.
3110 * buffer.c (unchain_overlay): Simplify. Add comment.
3111 * marker.c (unchain_marker): Simplify. Fix comments.

3122 (save_restriction_save): Use build_marker.
3123 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
3124 * window.c (save_window_save): Likewise.
3126 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3128 Do not use Fdelete_overlay in delete_all_overlays
3129 to avoid redundant calls to unchain_overlay.
3130 * buffer.c (drop_overlay): New function.
3131 (delete_all_overlays, Fdelete_overlay): Use it.
3132 * minibuf.c (get_minibuffer): Fix comment.
3134 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3136 Port to OpenBSD 5.1 amd64.
3137 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
3138 This is needed for OpenBSD, and should be harmless on all BSD systems.
3139 Also, include <sys/sysctl.h>, as it should be available on all
3140 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
3141 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
3142 use p_pid member, not kp_proc.pid.
3144 2012-07-06 Glenn Morris <rgm@gnu.org>
3146 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
3148 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
3150 More xmalloc and related cleanup.
3151 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
3152 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

3159 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
3161 Omit needless casts involving void * pointers and allocation.
3162 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
3163 as the former is more robust if P's type is changed.
3164 Prefer xzalloc to xmalloc + memset 0.
3165 Simplify malloc-or-realloc to realloc.
3166 Don't worry about xmalloc returning a null pointer.
3167 Prefer xstrdup to xmalloc + strcpy.
3168 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
3170 * keyboard.c (apply_modifiers_uncached): Prefer local array to
3171 alloca of a constant.
3173 2012-07-05 Eli Zaretskii <eliz@gnu.org>
3175 * xdisp.c (display_line): Fix horizontal pixel coordinates when
3176 hscroll is larger than the line width. Fixes long and futile
3177 looping inside extend_face_to_end_of_line (on a TTY) producing
3178 glyphs that are not needed and thrown away.
3180 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

3192 not defined (Bug#11768).
3193 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
3194 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
3195 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
3196 followed by gtk_box_set_homogeneous (Bug#11768).
3197 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
3198 (update_theme_scrollbar_width, xg_create_scroll_bar):
3199 Use gtk_scrollbar_new (Bug#11768).
3200 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

3208 * xdisp.c (window_hscroll_limited): New function.
3209 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
3210 coordinates when window's hscroll is set to insanely large

3277 Problem reported by Troels Nielsen in
3278 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

3282 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
3283 This should be fixed in a better way; see Eli Zaretskii in
3284 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
3285 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
3287 * fileio.c (time_error_value): Rename from special_mtime.
3288 The old name's problems were noted by Eli Zaretskii in
3289 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
3291 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
3292 This variable's comment says Emacs needs at least one GDB-visible
3293 symbol of type enum pvec_type, to work around GDB problems.
3294 The symbol's value doesn't matter.
3296 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
3297 that causes compilation to fail on pre-C99 compilers.
3299 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
3301 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

3307 headers for buffer_defaults and buffer_local_symbols.
3308 Reported by Juanma Barranquero <lekktu@gmail.com>.
3310 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
3312 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
3313 * lisp.h (enum pvec_type): Use fewer bits.
3314 (PSEUDOVECTOR_SIZE_BITS): New constant.
3315 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
3316 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
3317 change in pvec_type.
3318 (PSEUDOVECTOR_TYPEP): New macro.

3324 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
3325 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
3326 (sweep_vectors): Use it. Use local var `total_bytes' instead of
3327 abusing vector->header.next.nbytes.
3328 (live_vector_p): Use PVEC_TYPE.
3329 (mark_object): Adapt code to extract pvectype. Use switch.
3331 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3333 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
3334 Tighten new eassert a bit.
3336 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3338 Fix compilation with --enable-gcc-warnings and -O1
3340 * doprnt.c (doprnt): Change type of tem to int, initialize
3341 to avoid compiler warning. Add eassert.
3342 * search.c (simple_search): Initialize match_byte to avoid
3343 compiler warning. Add eassert.
3345 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3347 Avoid weird behavior with large horizontal scrolls.
3348 Without this change, for example, large hscroll values would
3349 mess up Emacs's display on Fedora 15 x86, presumably due to
3350 overflows in int calculations in the display code.
3351 Also, if buffers had long lines, Emacs would freeze.
3352 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
3353 (set_window_hscroll): New function, containing the old guts of
3354 Fset_window_hscroll. Return the clipped value.
3355 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
3356 This avoids the need to check against PTRDIFF_MAX.
3358 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
3360 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3362 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
3364 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3366 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
3367 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
3368 since GCC 4.4.6 issues a bogus warning for them.
3370 Fix bugs in file timestamp newness comparisons.
3371 * fileio.c (Ffile_newer_than_file_p):
3372 * lread.c (Fload): Use full timestamp resolution of files,
3373 not just the 1-second resolution, so that files that are only
3374 slightly newer still count as newer.
3375 * fileio.c (Ffile_newer_than_file_p): Don't assume file
3376 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
3378 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
3380 * fileio.c: Improve handling of file time marker. (Bug#11852)
3381 (special_mtime): New function.
3382 (Finsert_file_contents, Fverify_visited_file_modtime):
3383 Use it to set special mtime values consistently.
3385 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
3387 * fileio.c (Finsert_file_contents): Properly handle st_mtime
3388 marker for non-existing file. (Bug#11852)
3390 2012-07-03 Glenn Morris <rgm@gnu.org>
3392 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
3393 and did not make it into globals.h).
3395 2012-07-03 Tom Tromey <tromey@redhat.com>
3397 * window.c (Fset_window_margins, Fset_window_fringes)

3431 * xterm.h: Remove EXFUN.
3433 2012-07-03 Glenn Morris <rgm@gnu.org>
3435 * lisp.h (Frandom): Make it visible to C.
3436 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
3437 buffer for invisible buffers. (Bug#1229)
3439 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3441 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
3442 values which aren't power of 2.
3443 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
3444 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
3447 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
3449 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
3451 * alloc.c (mark_object): Revert part of last patch to use `switch'.
3453 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3455 * alloc.c (allocate_vector_block): Remove redundant
3456 calls to mallopt if DOUG_LEA_MALLOC is defined.
3457 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
3458 avoid calls to mallopt if zero_vector is returned.
3460 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3462 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
3463 is enabled, avoid dereferencing NULL current_sblock if
3466 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3468 Cleanup basic buffer management.
3469 * buffer.h (struct buffer): Change layout to use generic vector
3470 marking code. Fix some comments. Change type of 'clip_changed'
3471 to bitfield. Remove unused #ifndef old.
3472 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
3473 (GET_OVERLAYS_AT): Fix indentation.
3474 (for_each_per_buffer_object_at): New macro.
3475 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

3477 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
3478 * alloc.c (allocate_buffer): Adjust to match new layout of
3479 struct buffer. Fix comment.
3480 (mark_overlay): New function.

3482 Lisp area of struct buffer.
3483 (mark_object): Use it. Adjust marking of misc objects
3484 and related comments.
3486 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
3488 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
3489 wrapper that is not needed because the wrapped code is a no-op (zero
3490 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
3491 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3493 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3495 * alloc.c (mark_buffer): Simplify. Remove prototype.
3496 (mark_object): Add comment. Reorganize marking of vector-like
3497 objects. Use CHECK_LIVE for all vector-like objects except buffers
3498 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3499 Avoid redundant calls to mark_vectorlike for bool vectors.
3501 2012-06-30 Glenn Morris <rgm@gnu.org>
3503 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3505 * epaths.in (PATH_SITELOADSEARCH): New.
3506 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3507 This is rather than relying on --enable-locallisppath elements
3508 having "site-lisp" in their names. (Bug#10208#25, 11658)
3510 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3512 * w32proc.c (sys_select): Accept and ignore one more argument.
3514 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3516 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3517 (pselect) [!MS_DOS]: Redirect to sys_select.
3519 * sysdep.c: Don't include dos.h and dosfns.h.
3521 * process.c (sys_select):
3522 * msdos.c (sys_select): Accept one more argument and ignore it.
3524 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3525 adapt data types and code to that.
3528 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3529 which clashes with the gnulib function of the same name.
3531 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3533 * font.c (font_style_to_value, font_style_symbolic)
3534 (font_prop_validate_style): Add type checks for values in
3537 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3539 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3542 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3544 * xdisp.c (try_window_id): Undo last change.
3546 * w32.c (getwd): Adjust commentary about startup_dir.
3547 (init_environment): Always call sys_access, even in non-MSVC
3548 builds. Don't chdir to the directory of the Emacs executable.
3549 This undoes code from 1997 which was justified by the need to
3550 "avoid conflicts when removing and renaming directories". But its
3551 downside was that every relative file name was being interpreted
3552 relative to the directory of the Emacs executable, which can never
3553 be TRT. In particular, it broke sys_access when called with
3554 relative file names.
3555 (sys_access): Map GetLastError to errno.
3557 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3559 * window.h (struct window): Change type of 'fringes_outside_margins'

3563 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3566 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3568 * gnutls.c (emacs_gnutls_handshake):
3569 Add QUIT to make the loop interruptible.
3571 2012-06-29 Glenn Morris <rgm@gnu.org>
3573 * charset.c (init_charset): Make lack of etc/charsets fatal.
3575 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3577 * editfns.c (region_limit): Fix type mismatch.
3579 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3581 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3582 undefined. Convert from xassert to eassert.
3583 * nsmenu.m: Convert from xassert to eassert.
3584 * nsterm.m: Likewise.
3586 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3588 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3590 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3592 Avoid integer overflow on scroll-left and scroll-right.
3593 * window.c (HSCROLL_MAX): New macro.
3594 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3595 overflow when requested scroll falls outside ptrdiff_t range.
3597 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3599 * window.h (struct window): Change type of 'hscroll',
3600 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3601 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3602 Adjust users accordingly.
3603 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3604 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3605 from EMACS_INT to ptrdiff_t.
3606 (make_window): Omit redundant initialization.
3608 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3610 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3612 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3614 * window.h (struct window): Change type of 'use_time' and
3615 'sequence_number' from Lisp_Object to int.
3616 * frame.c (make_frame): Adjust users accordingly.
3617 * print.c (print_object): Likewise.
3618 * window.c (select_window, Fwindow_use_time, make_parent_window)
3619 (make_window): Likewise.
3621 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3623 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
3624 enabled with --enable-checking=[all,glyphs] configure option.
3625 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3626 adjust comments accordingly.
3627 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
3628 undefined, adjust comments accordingly.

3749 Use sprintf return value instead of invoking strlen on result.
3750 In the old days this wasn't portable, since some sprintf
3751 implementations returned char *. But they died out years ago and
3752 Emacs already assumes sprintf returns int.
3753 Similarly for float_to_string.
3754 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

3762 Use sprintf or float_to_string result to avoid need to call strlen.
3763 * data.c (Fnumber_to_string):
3764 Use make_unibyte_string, since the string must be ASCII.
3765 * lisp.h, print.c (float_to_string): Now returns int length.
3766 * term.c (produce_glyphless_glyph):
3767 Use sprintf result rather than recomputing it.
3769 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3770 * Makefile.in (ALL_CFLAGS):

3802 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

3805 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3807 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3808 instead of truncating it to 63 (admittedly a generous limit).

3868 * keyboard.c (kbd_buffer_get_event):
3869 * process.c (Faccept_process_output):
3870 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3871 This improves on the previous patch, which introduced a bug
3872 when time_t is unsigned and as wide as intmax_t.
3873 See <http://bugs.gnu.org/9000#51>.
3875 2012-06-23 Eli Zaretskii <eliz@gnu.org>

3904 language ID in the event parameters.
3906 * w32term.c (w32_read_socket): Put the new keyboard codepage into

3938 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3940 Support higher-resolution time stamps (Bug#9000).
3941 The time stamps are only nanosecond-resolution at the C level,
3942 since that's the best that any real-world system supports now.
3943 But they are picosecond-resolution at the Lisp level, as that's
3944 easy, and leaves room for future OS improvements.
3946 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3949 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3950 Don't get current time unless it's needed.
3952 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3953 now provides it if it's absent.
3954 (start_atimer): Port to higher-res time stamps.
3955 Check for time stamp overflow. Don't get current time more
3956 often than is needed.
3958 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3959 Include systime.h, not time.h.
3960 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3962 * dired.c: Include stat-time.h.
3963 (Ffile-attributes): File times now have higher resolution.

3966 (struct image): Timestamp now has higher resolution.
3968 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3969 has at least microseconds now. All uses removed.
3970 (update_frame, update_single_window, update_window, update_frame_1)
3971 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3972 (duration_to_sec_usec): Remove; no longer needed.
3974 * editfns.c (time_overflow): Now extern.
3975 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3976 (float-time, Fformat_time_string, Fcurrent_time_string)

3980 (decode_time_components, lisp_seconds_argument): New functions.
3981 (make_time): Now static.
3982 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3983 Report an error if the time is invalid, rather than having the caller
3986 * fileio.c: Include <stat-time.h>
3987 (Fcopy_file): Copy higher-resolution time stamps.
3988 Prefer to set the time stamp via a file descriptor if that works.

3990 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3991 (Fvisited_file_modtime, Fset_visited_file_modtime):
3992 Support higher-resolution time stamps.
3994 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3996 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3998 * image.c (prepare_image_for_display, clear_image_cache)
3999 (lookup_image): Port to higer-resolution time stamps.
4001 * keyboard.c (start_polling, bind_polling_period):
4002 Check for time stamp overflow.
4003 (read_char, kbd_buffer_get_event, timer_start_idle)
4004 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
4005 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
4006 Port to higher-resolution time stamps. Do not assume time_t is signed.
4007 (decode_timer): New function. Timers are now vectors of length 9,
4008 not 8, to accommodate the picosecond component.
4009 (timer_check_2): Use it.
4011 * nsterm.m (select_timeout, timeval_subtract): Remove.
4012 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
4013 as they're a bit more accurate and handle overflow better.
4014 (ns_select): Change prototype to be compatible with pselect.
4015 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
4016 * nsterm.h (ns_select): Adjust prototype.
4018 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
4019 us-resolution time stamps.
4020 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
4022 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
4024 * lisp.h (time_overflow): New decl.
4025 (wait_reading_process_output): First arg is now intmax_t, not int,
4026 to accommodate larger waits.
4028 * process.h (struct Lisp_Process.read_output_delay):
4029 Now counts nanoseconds, not microseconds.
4030 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
4032 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
4033 (wait_reading_process_output):
4034 Port to ns-resolution time stamps.
4035 (Faccept_process_output, wait_reading_process_output):
4036 Check for time stamp overflow. Do not assume time_t is signed.
4037 (select_wrapper): Remove; we now use pselect.
4038 (Fprocess_attributes): Now generates ns-resolution time stamps.
4040 * sysdep.c: Include utimens.h. Don't include utime.h
4041 or worry about struct utimbuf; gnulib does that for us now.
4042 (gettimeofday): Remove; gnulib provides a substitute.
4043 (make_timeval): New function.
4044 (set_file_times): Now sets ns-resolution time stamps.
4045 New arg FD; all uses changed.
4046 (time_from_jiffies, ltime_from_jiffies, get_up_time)
4047 (system_process_attributes):
4048 Now returns ns-resolution time stamp. All uses changed.
4049 Check for time stamp overflow.
4051 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
4052 provides a substitute now.
4054 * systime.h: Include timespec.h rather than sys/time.h and time.h,
4055 since it guarantees struct timespec.
4056 (EMACS_TIME): Now struct timespec, so that we can support
4057 ns-resolution time stamps.
4058 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4059 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4060 (EMACS_USECS): Remove.
4061 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4062 so multiply the arg by 1000 before storing it.
4063 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
4065 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
4066 Port to ns-resolution time stamps.
4067 (EMACS_TIME_NEG_P): Remove; replaced by....
4068 (EMACS_TIME_SIGN): New macro.
4069 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
4070 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

4072 (make_timeval, make_lisp_time, decode_time_components): New decls.
4073 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
4074 that it mishandled time_t overflow. You can't compare by subtracting!
4075 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
4076 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
4078 * term.c: Include <sys/time.h>.
4079 (timeval_to_Time): New function, for proper overflow wraparound.
4080 (term_mouse_position, term_mouse_click): Use it.
4082 * undo.c (record_first_change): Support higher-resolution time stamps
4084 (Fprimitive_undo): Use them when restoring time stamps.
4086 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
4087 (w32_get_internal_run_time):
4088 Port to higher-resolution Emacs time stamps.
4089 (ltime): Now accepts single 64-bit integer, as that's more convenient
4092 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
4094 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
4095 for compatibility with pselect. Support ns-resolution time stamps.
4097 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
4099 * xselect.c (wait_for_property_change, x_get_foreign_selection):
4100 Check for time stamp overflow, and support ns-resolution time stamps.
4102 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
4103 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
4104 (timeval_subtract): Remove; no longer needed.
4105 (XTflash, XTring_bell, x_wait_for_event):
4106 Port to ns-resolution time stamps. Don't assume time_t is signed.
4108 2012-06-22 Chong Yidong <cyd@gnu.org>
4110 * xdisp.c (x_consider_frame_title): Revert last change.
4112 2012-06-22 Eli Zaretskii <eliz@gnu.org>
4114 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled

4390 as the union type is for debugging, not for production.
4391 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
4392 Use an inline function on all platforms when using the union type,
4393 since this is simpler and 'static inline' can be used portably

4538 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4539 would mishandle a string argument "Xc" if X was a multibyte
4540 character of length 2: it would truncate after X's first byte
4541 rather than including all of X.

4592 * minibuf.c (Fassoc_string): Remove duplicate declaration.
4594 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
4595 Convert pctcpu and pctmem to Lisp float properly.
4596 Let the compiler fold better, as 100.0/0x8000 is exact.
4598 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
4600 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
4603 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
4605 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
4607 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
4609 For a 'struct window', replace some Lisp_Object fields to
4610 bitfields where appropriate, remove unused fields.
4611 * window.h (struct window): Remove unused 'last_mark_x' and
4612 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
4613 change it's type from Lisp_Object to bitfield.
4614 Change type of 'force_start', 'optional_new_start',
4615 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
4616 fields from Lisp_Object to bitfield. Adjust users accordingly.
4618 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4620 Pacify gcc -Wdouble-precision when using Xaw.
4621 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
4622 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
4623 Use 'float' consistently, rather than 'float' in most places
4624 and 'double' in a couple of places.
4626 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4628 * xdisp.c (handle_stop): Detect whether we have overlay strings
4629 loaded by testing it->current.overlay_string_index to be
4630 non-negative, instead of checking whether n_overlay_strings is
4631 positive. (Bug#11587)
4633 2012-05-31 Chong Yidong <cyd@gnu.org>
4635 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
4637 * doc.c (Fsubstitute_command_keys): Doc fix.
4639 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4641 * search.c (search_buffer): Remove calls to
4642 r_alloc_inhibit_buffer_relocation, as it is now called by
4643 maybe_unify_char, which was the cause of relocation of buffer text
4646 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4648 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4649 for the duration of call to load_charset, to avoid problems with
4650 callers of maybe_unify_char that access buffer text through C
4653 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4654 decrement the inhibition flag, instead of just setting or
4657 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4659 Remove obsolete '#define static' cruft.
4660 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4661 This #undef was "temporary" in 2000; it is no longer needed
4662 now that '#define static' has gone away.
4663 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4664 (gray_bitmap_bits): Remove; no longer needed.
4665 All uses replaced with definiens.
4666 * xterm.c: Include "bitmaps/gray.xbm".
4668 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4670 Clean up __executable_start, monstartup when --enable-profiling.
4671 The following changes affect the code only when profiling.
4672 * dispnew.c (__executable_start): Rename from safe_bcopy.
4673 Define only on platforms that need it.
4674 * emacs.c: Include <sys/gmon.h> when profiling.
4675 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
4676 (__executable_start): Remove decl, since lisp.h does it now.
4677 (safe_bcopy): Remove decl; no longer has that name.
4678 (main): Coalesce #if into single bit of code, for simplicity.
4679 Cast pointers to uintptr_t, since standard libraries want integers
4681 * lisp.h (__executable_start): New decl.
4683 2012-05-31 Glenn Morris <rgm@gnu.org>
4685 * image.c (Fimagemagick_types): Doc fix.
4687 2012-05-30 Jim Meyering <meyering@redhat.com>
4689 * callproc.c (Fcall_process_region): Include directory component
4690 in mkstemp error message (Bug#11586).
4692 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4694 * alloc.c, lisp.h (make_pure_vector): Now static.
4696 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

4702 (Qdefun): Move from eval.c.
4703 * lisp.h (Qdefun): Remove.
4704 * lread.c (read1): Tiny simplification.
4706 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4708 Do not create empty overlays with the evaporate property (Bug#9642).
4709 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4710 Bug#9642, but explicitly check that the buffer the overlay would
4711 be moved to is live and rearrange lines to make sure that errors
4712 will not put the overlay in an inconsistent state.
4713 (Fdelete_overlay): Cosmetics.
4715 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4717 * w32term.c (my_bring_window_to_top): New function.
4718 (x_raise_frame): Use handle returned by DeferWindowPos, which
4719 could be different from the original one.
4720 Call my_bring_window_to_top instead of my_set_foreground_window.
4723 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4724 by calling BringWindowToTop.
4726 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4727 (WM_EMACS_END): Increase by one.
4729 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4731 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4732 This avoids undefined behavior that might cause the eassert
4733 to not catch an out-of-range value.
4735 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4737 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4738 Update dependencies.
4740 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4742 * bidi.c (bidi_mirror_char): Fix last change.
4744 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
4746 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
4747 when referring to sectname field in printf format.
4749 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4751 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4752 Only r_alloc_inhibit_buffer_relocation needed to be added;
4753 the others were already declared.
4755 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4756 before checking whether it's out of range. Put the check inside
4758 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4760 2012-05-27 Ken Brown <kbrown@cornell.edu>
4762 * callproc.c (Fcall_process): Restore a line that was accidentally
4763 commented out in the 2011-02-13 change (bug#11547).
4765 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4767 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4768 defined on ralloc.c.
4770 * buffer.c [REL_ALLOC]: Remove prototypes of
4771 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4772 they are now on lisp.h.
4774 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4776 * search.c (search_buffer): Use it to inhibit relocation of buffer
4777 text while re_search_2 is doing its job, because re_search_2 is
4778 passed C pointers to buffer text. (Bug#11519)
4780 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4783 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4784 state after an additional call to move_it_in_display_line_to, keep
4785 the values of it->max_ascent and it->max_descent found for the
4787 (pos_visible_p): Revert the comparison against bottom_y to what it
4788 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4791 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4793 Fix coding-related core dumps with gcc -ftrapv.
4794 The code was computing A - B, where A and B are pointers, and B is
4795 random garbage. This can lead to core dumps on platforms that
4796 have special pointer registers, and it also leads to core dumps on
4797 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4798 A - B only when B is initialized properly.
4799 * coding.c (coding_set_source, coding_set_destination): Return void.
4800 (coding_change_source, coding_change_destinations): New functions,
4801 with the old behaviors of coding_set_source and coding_set_destination.
4802 All callers that need an offset changed to use these new functions.
4804 2012-05-26 Glenn Morris <rgm@gnu.org>
4806 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4808 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4810 Extend mouse support on W32 text-mode console.
4811 * xdisp.c (draw_row_with_mouse_face):
4812 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4814 * w32console.c: Include window.h.
4815 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4817 (initialize_w32_display): Initialize mouse-highlight data.
4819 * w32inevt.c: Include termchar.h and window.h.
4820 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4821 moves, call note_mouse_highlight. If help_echo changed, call
4822 gen_help_event to produce help-echo message in the echo area.
4823 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4826 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4828 * lread.c (read1): Simplify slightly to avoid an overflow warning
4829 with GCC 4.7.0 on x86-64.
4831 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4833 * bidi.c (bidi_mirror_char): Revert last change: an int is
4834 definitely wide enough here.
4836 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4838 Fix integer width and related bugs (Bug#9874).
4839 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4840 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4841 (string_bytes, check_sblock, allocate_string_data):
4842 (compact_small_strings, Fmake_bool_vector, make_string)
4843 (make_unibyte_string, make_multibyte_string)
4844 (make_string_from_bytes, make_specified_string)
4845 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
4846 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4848 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4849 (allocate_pseudovector):
4850 Use int, not EMACS_INT, where int is wide enough.
4851 (inhibit_garbage_collection, Fgarbage_collect):
4852 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4853 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4854 int might not be wide enough.
4855 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4856 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4857 (bidi_at_paragraph_end, bidi_find_paragraph_start)
4858 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4859 (bidi_level_of_next_char, bidi_move_to_visually_next):
4860 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4861 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4862 (Fkill_buffer, Fset_buffer_major_mode)
4863 (advance_to_char_boundary, Fbuffer_swap_text)
4864 (Fset_buffer_multibyte, overlays_at, overlays_in)
4865 (overlay_touches_p, struct sortvec, record_overlay_string)
4866 (overlay_strings, recenter_overlay_lists)
4867 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4868 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4869 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4870 (Foverlay_recenter, last_overlay_modification_hooks_used)
4871 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4872 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4873 (validate_region): Omit unnecessary test for b <= e,
4874 since that's guaranteed by the previous test.
4875 (adjust_overlays_for_delete): Avoid pos + length overflow.
4876 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4877 (report_overlay_modification):
4878 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4879 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4880 Omit pointer cast, which isn't needed anyway, and doesn't work
4881 after the EMACS_INT -> ptrdiff_t change.
4882 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4883 * buffer.h: Adjust decls to match defn changes elsewhere.
4884 (struct buffer_text, struct buffer):
4885 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4886 Use EMACS_INT, not int, where int might not be wide enough.
4887 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4888 not int, to avoid needless 32-bit limit on 64-bit hosts.
4889 (exec_byte_code): Use tighter memory-full test, one that checks
4890 for alloca overflow. Don't compute the address of the object just
4891 before an array, as that's not portable. Use EMACS_INT, not
4892 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4893 * callint.c (Fcall_interactively):
4894 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4895 * callproc.c (call_process_kill, Fcall_process):
4896 Don't assume pid_t fits into an Emacs fixnum.
4897 (call_process_cleanup, Fcall_process, child_setup):
4898 Don't assume pid_t fits into int.
4899 (call_process_cleanup, Fcall_process, delete_temp_file)
4900 (Fcall_process_region):
4901 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4902 (Fcall_process): Simplify handling of volatile integers.
4903 Use int, not EMACS_INT, where int will do.
4904 * casefiddle.c (casify_object, casify_region, operate_on_word)
4905 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4906 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4907 (casify_object): Avoid integer overflow when overallocating buffer.
4908 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4909 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4910 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4911 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4912 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4913 integers are now checked earlier. All uses replaced with XINT.
4915 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4916 For CCL_MapSingle, check that content and value are in int range.
4917 (ccl_driver, Fregister_code_conversion_map):
4918 Check that Vcode_version_map_vector is a vector.
4919 (resolve_symbol_ccl_program): Check that vector header is in range.
4920 Always copy the vector, so that we can check its contents reliably
4921 now rather than having to recheck each instruction as it's being
4922 executed. Check that vector words fit in 'int'.
4923 (ccl_get_compiled_code, Fregister_ccl_program)
4924 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4925 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4926 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4927 contents are in range.
4928 (Fccl_execute_on_string): Check that status is in range.
4929 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4930 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4931 Accept and return EMACS_INT, not int, because callers can pass values
4933 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4934 (multibyte_chars_in_text, parse_str_as_multibyte)
4935 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
4936 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4937 (string_escape_byte8, Fget_byte):
4938 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4939 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4940 avoid mishandling large integers.
4941 * character.h: Adjust decls to match defn changes elsewhere.
4942 * charset.c (load_charset_map_from_file, find_charsets_in_text)
4943 (Ffind_charset_region):
4944 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4945 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
4946 (load_charset_map_from_vector, Fdefine_charset_internal):
4947 Don't assume fixnum fits in int.
4948 (load_charset_map_from_vector, Fmap_charset_chars):
4949 Remove now-unnecessary CHECK_NATNUMs.
4950 (Fdefine_charset_internal): Check ranges here, more carefully.
4951 Don't rely on undefined behavior with signed left shift overflow.
4952 Don't assume unsigned int fits into fixnum, or that fixnum fits
4953 into unsigned int. Don't require max_code to be a valid fixnum;
4954 that's not true for gb10830 4-byte on a 32-bit host. Allow
4955 invalid_code to be a cons, for the same reason. Require code_offset
4956 to be a character. Avoid int overflow if max_char is close
4958 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4959 this is intended anyway and avoids some undefined behavior.
4960 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4961 INDEX_TO_CODE_POINT, as that's what it expects.
4962 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4963 * charset.h (DECODE_CHAR): Return int, not unsigned;
4964 this is what was intended anyway, and it avoids undefined behavior.
4965 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4966 integer-overflow issues.
4967 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4968 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4969 where the argument is EMACS_INT, and this behavior is not intended.
4970 * chartab.c (Fmake_char_table, Fset_char_table_range)
4971 (uniprop_get_decoder, uniprop_get_encoder):
4972 Don't assume fixnum fits in int.
4973 * cmds.c (move_point): New function, that does the gist of
4974 Fforward_char and Fbackward_char, but does so while checking
4975 for integer overflow more accurately.
4976 (Fforward_char, Fbackward_char): Use it.
4977 (Fforward_line, Fend_of_line, internal_self_insert)
4978 (internal_self_insert):
4979 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4980 Fix a FIXME, by checking for integer overflow when calculating
4981 target_clm and actual_clm.
4982 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

5729 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
5731 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
5732 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
5734 2012-05-18 Eli Zaretskii <eliz@gnu.org>
5736 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
5738 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
5739 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
5741 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
5742 reference to image_cache->refcount.
5743 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
5745 2012-05-17 Juri Linkov <juri@jurta.org>
5747 * search.c (Fword_search_regexp, Fword_search_backward)
5748 (Fword_search_forward, Fword_search_backward_lax)
5749 (Fword_search_forward_lax): Move functions to isearch.el
5750 (bug#10145, bug#11381).
5752 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
5754 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
5756 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
5758 * lread.c (init_obarray): Declare Qt and Qnil as special.
5760 2012-05-14 Glenn Morris <rgm@gnu.org>
5762 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
5763 Put "libexec" before "bin", for the sake of init_callproc_1.
5765 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5767 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
5769 * unexaix.c: Port to more-recent AIX compilers.
5770 (report_error, report_error_1, make_hdr, copy_sym)
5771 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
5772 Make arguments const char *, not char *, to avoid violations of C
5773 standard and to fix some AIX warnings reported by Gilles Pion.
5775 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5777 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
5778 already have overlays loaded.
5779 (handle_single_display_spec): Before returning without displaying
5780 fringe bitmap, synchronize the bidi iterator with the main display
5781 iterator, by calling iterate_out_of_display_property.
5782 (iterate_out_of_display_property): Detect buffer iteration by
5783 testing that it->string is a Lisp string.
5784 (get_next_display_element): When the current object is exhausted,
5785 and there's something on it->stack, call set_iterator_to_next to
5786 proceed with what's on the stack, instead of returning zero.
5787 (set_iterator_to_next): If called at the end of a Lisp string,
5788 proceed to consider_string_end without incrementing string
5789 position. Don't increment display vector index past the end of
5790 the display vector. (Bug#11417)
5791 (pos_visible_p): Don't report a position visible when move_it_to
5792 stopped at the last line of window, which happens to be scanned
5793 backwards by the bidi iteration. (Bug#11464)
5795 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5797 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5798 and right-margin display specs even if the spec is invalid or we
5799 are on a TTY, and thus unable to display on the fringes.
5800 That's because the text with the property will not be displayed anyway,
5801 so we need to signal to the caller that this is a "replacing"
5802 display spec. This fixes display when the spec is invalid or we
5805 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5807 * unexaix.c (make_hdr): Fix typo in prototype.
5808 This bug broke the build on AIX. Problem reported by Gilles Pion.
5810 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5812 * keyboard.c (kbd_buffer_get_event): Read special events also in
5813 batch mode. (Bug#11415)
5815 2012-05-12 Glenn Morris <rgm@gnu.org>
5817 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5819 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5821 * lisp.mk (lisp): Add newcomment.elc.
5823 2012-05-12 Glenn Morris <rgm@gnu.org>
5825 * Makefile.in (MKDIR_P): New, set by configure.
5826 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5828 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5830 Remove unused function hourglass_started.
5831 * dispextern.h (hourglass_started):
5832 * w32fns.c (hourglass_started):
5833 * xdisp.c (hourglass_started): Remove.
5835 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5837 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5838 Update dependencies.
5840 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5842 * xgselect.c (xg_select): Put maxfds+1 into a var.
5843 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5845 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5847 2012-05-10 Dave Abrahams <dave@boostpro.com>
5849 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5850 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5852 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5854 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5855 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5856 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5857 Initialize xd_registered_buses.
5859 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5861 Untag more efficiently if USE_LSB_TAG.
5862 This is based on a proposal by YAMAMOTO Mitsuharu in
5863 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5864 For an admittedly artificial (nth 8000 longlist) benchmark on
5865 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5866 Emacs's overall text size by 1%.
5867 * lisp.h (XUNTAG): New macro.
5868 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5869 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5870 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5871 * eval.c (Fautoload):
5872 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5873 * frame.h (XFRAME): Use XUNTAG.
5875 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5876 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5877 Remove unportable assumptions about print widths of types like
5879 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5880 intptr_t when converting between pointer and integer, to avoid GCC
5881 warnings about wrong width.
5883 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5885 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5886 stack for each reader_thread, instead of defaulting to 8MB
5887 determined by the linker. This avoids failures in creating
5888 subprocesses on Windows 7, see the discussion in this thread:
5889 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5891 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5893 Fix up display of the *Minibuf-0* buffer in the mini window.
5894 * keyboard.c (read_char): Don't clear the echo area if there's no
5896 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5897 contents of *Minibuf-0*) if there's no message displayed in its stead.
5899 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5901 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5904 2012-05-06 Chong Yidong <cyd@gnu.org>
5906 * lisp.mk (lisp): Update.
5908 2012-05-05 Jim Meyering <meyering@redhat.com>
5910 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5912 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5914 * data.c (PUT_ERROR): New macro.
5915 (syms_of_data): Use it. Add new error type `user-error'.
5916 * undo.c (user_error): New function.
5917 (Fprimitive_undo): Use it.
5918 * print.c (print_error_message): Adjust print style for `user-error'.
5919 * keyboard.c (user_error): New function.
5920 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5922 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5924 Do not limit current-time-string to years 1000..9999.
5925 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5926 (Fcurrent_time_string): Support any year that is supported by the
5927 underlying localtime representation. Don't use asctime, as it
5928 has undefined behavior for years outside the range -999..9999.
5930 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5932 Fix race conditions involving setenv, gmtime, localtime, asctime.
5933 Without this fix, interrupts could mess up code that uses these
5934 nonreentrant functions, since setting TZ invalidates existing
5935 tm_zone or tzname values, and since most of these functions return
5936 pointers to static storage.
5937 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5938 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5939 Grow the critical sections to include not just invoking
5940 localtime/gmtime, but also accessing these functions' results
5941 including their tm_zone values if any, and any related TZ setting.
5942 (format_time_string): Last arg is now struct tm *, not struct tm **,
5943 so that the struct tm is saved in the critical section.
5944 All callers changed. Simplify allocation of initial buffer, partly
5945 motivated by the fact that memory allocation needs to be outside
5946 the critical section.
5948 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5950 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5951 with RESET_INTERVAL.
5953 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5954 Remove duplicated buffer name initialization.
5956 2012-05-02 Jim Meyering <jim@meyering.net>
5958 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5960 * xfns.c (x_window): Use xstrdup (Bug#11375).
5962 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5964 * xdisp.c (pos_visible_p): If already at a newline from the
5965 display string before the 'while' loop, don't walk back the glyphs
5966 from it3.glyph_row. Solves assertion violation when the display
5967 string begins with a newline (egg.el). (Bug#11367)
5969 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5971 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5974 2012-05-01 Glenn Morris <rgm@gnu.org>
5976 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5977 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5978 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5979 All were removed before 23.1.
5981 * dispnew.c: Remove HAVE_LIBNCURSES test;
5982 it is always true on relevant platforms.
5984 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5985 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5987 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5989 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5991 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5992 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5995 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5997 Do not avoid creating empty evaporating overlays (Bug#9642).
5998 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5999 That is, do not delete an evaporating overlay if it becomes
6000 empty after its bounds are adjusted to fit within its buffer.
6001 This fix caused other problems, and I'm reverting it until we get
6002 to the bottom of them.
6004 2012-04-27 Chong Yidong <cyd@gnu.org>
6006 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
6008 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6010 * xdisp.c (pos_visible_p): If the window start position is beyond
6011 ZV, start the display from buffer beginning. Prevents assertion
6012 violation in init_iterator when the minibuffer window is scrolled
6015 * window.c (window_scroll_pixel_based): Likewise.
6017 2012-04-27 Chong Yidong <cyd@gnu.org>
6019 * keymap.c (where_is_internal): Doc fix (Bug#10872).
6021 2012-04-27 Glenn Morris <rgm@gnu.org>
6023 * fileio.c (Fcopy_file, Fset_file_selinux_context):
6024 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
6026 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6028 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
6029 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
6031 2012-04-26 Eli Zaretskii <eliz@gnu.org>
6033 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
6034 display element, check also the underlying string or buffer
6035 character. (Bug#11341)
6037 * w32menu.c: Include w32heap.h.
6038 (add_menu_item): If the call to AppendMenuW (via
6039 unicode_append_menu) fails, disable Unicode menus only if we are
6040 running on Windows 9X/Me.
6042 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6044 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6045 (xgetint): Add missing shift for LSB tags.
6047 2012-04-24 Martin Rudalics <rudalics@gmx.at>
6049 * keyboard.c (read_char): Don't wipe echo area for select window
6050 events: These might get delayed via `mouse-autoselect-window'
6053 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
6055 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
6056 manipulation of :loaded-from data.
6058 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6060 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6061 now a cons (bug#11311).
6063 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
6065 Do not create empty overlays with the evaporate property (Bug#9642).
6066 * buffer.c (Fmove_overlay): Delete an evaporating overlay
6067 if it becomes empty after its bounds are adjusted to fit within
6068 its buffer. Without this fix, in a nonempty buffer (let ((o
6069 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
6070 yields an empty overlay that has the evaporate property, which is
6071 not supposed to happen.
6073 Fix minor GTK3 problems found by static checking.
6074 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
6075 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6076 (struct _EmacsFixedClass, emacs_fixed_get_type):
6077 Move decls here from emacsgtkfixed.h, since they needn't be public.

6079 (emacs_fixed_class_init): Omit unused local.
6080 (emacs_fixed_child_type): Remove; unused.

6084 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
6085 (EMACS_FIXED_GET_CLASS): Remove; unused.
6086 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
6088 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
6089 Problem reported by Juanma Barranquero for Windows -Wunused-function.
6091 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6093 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
6094 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
6095 (__malloc_size_t, __malloc_ptrdiff_t):
6096 Remove. All uses removed, replaced by the definiens if needed,
6097 since we can assume C89 or better now.
6098 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
6099 (protect_malloc_state, align, get_contiguous_space)
6100 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

6106 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
6107 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
6108 Define using prototypes, not old style.
6109 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
6110 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
6111 (align): Don't assume that signed integer overflow wraps around.
6112 Omit unused local var.
6113 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
6114 (_free_internal_nolock, memalign, mallochook, reallochook):
6115 Omit no-longer-needed casts.
6116 (valloc): Use getpagesize, not __getpagesize.
6117 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
6118 (struct hdr): The 'magic' member is now size_t, not unsigned long.
6120 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
6122 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
6124 Move functions from C to Lisp. Make non-blocking method calls
6125 the default. Implement further D-Bus standard interfaces.
6127 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
6128 (QCdbus_request_name_allow_replacement)

6167 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6169 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
6170 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
6171 Do not assume ptrdiff_t is the same width as 'int'.
6173 * alloc.c: Handle unusual debugging option combinations.
6174 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
6175 since the two debugging options are incompatible.
6176 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
6178 (mem_init, mem_insert, mem_insert_fixup):
6179 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
6180 (NEED_MEM_INSERT): Remove; no longer needed.

6188 * sysdep.c [__FreeBSD__]: Minor cleanups.
6189 (list_system_processes, system_process_attributes) [__FreeBSD__]:
6190 Use Emacs indenting style more consistently. Avoid some casts.
6191 Use 'double' consistently rather than mixing 'float' and 'double'.

6209 * print.c (print_preprocess): Only check print_depth if print-circle
6211 (print_object): Check for cycles even when print-circle is nil and
6212 print-gensym is t, but only check print_depth if print-circle is nil.
6214 2012-04-20 Chong Yidong <cyd@gnu.org>
6216 * process.c (wait_reading_process_output): If EIO occurs on a pty,
6217 set the status to "failed" and ensure that sentinel is run.
6219 2012-04-20 Glenn Morris <rgm@gnu.org>

6230 row, return zero immediately.
6231 (try_cursor_movement): If inside continuation line, don't back up
6232 farther than the first row after the header line, if any.
6233 Don't consider the header-line row as "partially visible", even if
6234 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
6236 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

6271 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
6272 New extern decls, to avoid calling undeclared functions.
6273 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
6274 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
6275 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
6276 (NEED_MEM_INSERT): New macro.
6277 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
6278 Remove one incorrect comment and fix another.

6292 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
6293 Remove decls. This fixes an "It stinks!".
6295 * alloc.c (which_symbols): Fix alignment issue / type clash.
6297 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
6299 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

6312 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
6313 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
6314 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
6315 * s/netbsd.h, s/sol2-6.h:
6316 Remove definition of GC_MARK_STACK, since the default now works.
6317 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
6318 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
6319 no longer the default.
6320 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
6322 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
6324 * lread.c (lisp_file_lexically_bound_p):

6345 2012-04-11 Daniel Colascione <dancol@dancol.org>
6347 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
6348 against is gone. It's better to use vfork now so that when Cygwin
6349 gains a new, working vfork, we use it automatically (bug#10398).
6351 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

6369 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
6371 * w32.c (w32_delayed_load): Record the full path of the library
6372 being loaded (bug#10424).
6374 2012-04-09 Glenn Morris <rgm@gnu.org>
6376 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
6377 not just in the obarray, before snarfing them. (Bug#11036)
6379 * Makefile.in ($(leimdir)/leim-list.el):
6380 Pass EMACS rather than BUILT_EMACS.

6389 Add convenience `GNUTLS_LOG2i' macro.
6391 * gnutls.c (gnutls_log_function2i): Convenience log function.
6392 (emacs_gnutls_read): Use new log functions,
6393 `gnutls_handshakes_tried' process member, and

6404 * minibuf.c (Fread_variable): Callers changed.
6406 2012-04-09 Eli Zaretskii <eliz@gnu.org>
6408 * xdisp.c (set_cursor_from_row): If the display string appears in
6409 the buffer at position that is closer to point than the position
6410 after the display string, display the cursor on the first glyph of
6411 the display string. Fixes cursor display when a 'display' text
6412 property immediately follows invisible text. (Bug#11094)
6414 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
6416 composite.c: use 'double' consistently
6417 * composite.c (get_composition_id): Use 'double' consistently
6418 instead of converting 'float' to 'double' and vice versa; this is
6419 easier to understand and avoids a GCC warning.
6421 2012-04-09 Glenn Morris <rgm@gnu.org>
6423 * Makefile.in: Generate leim-list with bootstrap-emacs, in
6424 preparation for dumping it with emacs. (Bug#4789)

6446 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
6447 (mark_memory): Mark Lisp_Objects only if pointers might hide in
6448 objects, as mark_maybe_pointer will catch them otherwise.
6449 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
6450 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
6452 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
6454 Fix typo that broke non-Windows builds.
6455 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

6466 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
6467 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
6468 [!WINDOWSNT]: New macros.
6469 (init_libxml2_functions, libxml2_loaded_p): New functions.
6470 (parse_region): Call fn_xmlCheckVersion instead of using the macro
6471 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
6472 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
6473 Calls xmlCleanupParser only if libxml2 was loaded (or statically
6475 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
6476 Call init_libxml2_functions before calling libxml2 functions.
6477 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
6479 * emacs.c: Don't include libxml/parser.h.
6480 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
6481 xmlCleanupParser directly.
6483 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
6485 2012-04-07 Eli Zaretskii <eliz@gnu.org>
6487 * indent.c (Fvertical_motion): If there is a display string at
6488 point, use it.vpos to compute how many lines to backtrack after
6489 move_it_to point. (Bug#11133)
6491 2012-04-06 Eli Zaretskii <eliz@gnu.org>
6493 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6494 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6495 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6496 macros related to unification of CJK characters. For the details,
6497 see the discussion following the message here:
6498 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6500 2012-04-04 Chong Yidong <cyd@gnu.org>
6502 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6504 2012-04-01 Eli Zaretskii <eliz@gnu.org>
6506 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

6514 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6516 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6517 position we get to after a call to move_it_to fails the
6518 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6519 only if we wind up in a string from display property. (Bug#11063)
6521 * window.c (Fdelete_other_windows_internal): Invalidate the row
6522 and column information about mouse highlight, so that redisplay
6523 restores it after reallocating the glyph matrices. (Bug#7464)
6525 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6526 string comes from a `display' text property, use the buffer
6527 position of that property as if we actually saw that position in
6529 (move_it_by_lines): Remove the assertion that
6530 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6531 violated when there's a before-string at the beginning of a line.
6534 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6536 * xdisp.c (append_space_for_newline): If the default face was
6537 remapped, use the remapped face for the appended newline.
6538 (extend_face_to_end_of_line): Use the remapped default face for
6539 extending the face to the end of the line.
6540 (display_line): Call extend_face_to_end_of_line when the default
6541 face was remapped. (Bug#11068)
6543 2012-03-29 Eli Zaretskii <eliz@gnu.org>

6565 handle-select-window too (Bug#8996).
6567 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
6569 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6571 2012-03-25 Kenichi Handa <handa@m17n.org>
6573 * dispextern.h (struct glyph): Change the bit length of
6574 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6576 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6578 * s/ms-w32.h (tzname): Include time.h before redirecting to
6579 _tzname. Fixes the MSVC build. (Bug#9960)

6583 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6586 * xterm.c (XTread_socket): Only modify handling_signal if

6589 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6591 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6592 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6593 when fetching a multibyte character consumes more bytes than
6594 CHAR_BYTES returns, due to unification of CJK characters in
6595 string_char. (Bug#11073)
6597 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6599 * process.c (wait_reading_process_output): Handle pty disconnect
6600 by refraining from sending oneself a SIGCHLD (bug#10933).

6611 2012-03-21 Chong Yidong <cyd@gnu.org>
6613 * xfaces.c (Vface_remapping_alist): Doc fix.
6615 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6617 * w32proc.c (Fw32_set_console_codepage)
6618 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

6623 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
6624 to reflect default non-nil value of redisplay-dont-pause.
6626 2012-03-19 Kenichi Handa <handa@m17n.org>

6629 it fit in a valid range (Bug#11003).
6631 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6633 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6634 that is not from display property, accept the row as a "cursor
6635 row" if one of the string's character has a non-nil `cursor'
6636 property. Fixes cursor positioning when there are newlines in
6637 overlay strings, e.g. in icomplete.el. (Bug#11035)
6639 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6641 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
6643 2012-03-12 Chong Yidong <cyd@gnu.org>
6645 * eval.c (inhibit_lisp_code): Rename from
6646 inhibit_window_configuration_change_hook; move from window.c.
6648 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6649 * window.c (run_window_configuration_change_hook)
6650 (syms_of_window): Callers changed.
6652 2012-03-11 Chong Yidong <cyd@gnu.org>
6654 * keymap.c (Fkey_description): Doc fix (Bug#9700).

6670 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6673 2012-03-03 Glenn Morris <rgm@gnu.org>

6688 * buffer.c (buffer-list-update-hook): Doc fix.
6690 2012-02-29 Eli Zaretskii <eliz@gnu.org>

6693 push_it before setting up the iterator for the first overlay
6694 string, even if we have an empty string loaded.
6695 (next_overlay_string): If there's an empty string on the iterator
6696 stack, pop the stack. (Bug#10903)
6698 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6700 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6701 Suggested by Stefan Monnier in
6702 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6703 * alloc.c (widen_to_Lisp_Object): New static function.
6704 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6705 and widening them to Lisp_Objects. This would work even if
6706 USE_LSB_TAG is defined and wide integers are used, which might
6707 happen in a future version of Emacs.
6709 2012-02-25 Chong Yidong <cyd@gnu.org>
6711 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

6726 call when setting menu-bar-lines and tool-bar-lines parameters.
6727 (unwind_create_frame_1): New helper function.
6729 * window.c (inhibit_window_configuration_change_hook): New var.
6730 (run_window_configuration_change_hook): Obey it.
6731 (syms_of_window): Initialize it.
6733 2012-02-22 Chong Yidong <cyd@gnu.org>

6748 when computing $valmask.
6750 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6751 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6752 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6753 It's useless in that case, and it can cause problems on hosts
6754 that allocate halves of EMACS_INT values separately.
6755 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6756 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6757 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6758 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6759 it avoids undefined behavior on hosts where shifting right by more
6760 than the word width has undefined behavior.
6762 2012-02-19 Chong Yidong <cyd@gnu.org>
6764 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
6765 (Funhandled_file_name_directory, Ffile_name_as_directory)

6784 2012-02-15 Chong Yidong <cyd@gnu.org>
6786 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

6805 as that creates a dangerous corner case.
6807 * window.c (Fdelete_window_internal): Invalidate the mouse
6808 highlight (Bug#9904).
6810 2012-02-12 Glenn Morris <rgm@gnu.org>

6840 2012-02-07 Chong Yidong <cyd@gnu.org>
6842 * buffer.c (Fbuffer_local_variables)
6843 (buffer_lisp_local_variables): Handle unbound vars correctly;
6844 don't let Qunbound leak into Lisp.
6846 2012-02-07 Glenn Morris <rgm@gnu.org>
6848 * image.c (Fimagemagick_types): Doc fix.
6850 * image.c (imagemagick-render-type): Change it from a lisp object

6885 Handle overflow when computing char display width (Bug#9496).
6886 * character.c (char_width): Return EMACS_INT, not int.
6887 (char_width, c_string_width): Check for overflow when
6888 computing the width; this is possible now that individual
6889 characters can have unbounded width. Problem introduced
6890 by merge from Emacs 23 on 2012-01-19.
6892 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

7032 (Fmake_directory_internal): Use it.

7562 behave as if the cursor position were at the window margin.
7564 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7565 and the cursor position is out of bounds, behave as if the cursor

7596 * dispnew.c (verify_row_hash): Call row_hash for computing the
7597 hash code of a row, instead of duplicating code from xdisp.c.
7599 * dispextern.h (row_hash): Add prototype.
7601 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

7635 * image.c (imagemagick_load_image): Fix typo.
7637 2011-11-14 Eli Zaretskii <eliz@gnu.org>
7639 * xdisp.c (display_line): Move the call to

7706 Avoid some portability problems by eschewing 'extern inline' functions.
7707 The trivial performance wins aren't worth the portability hassles; see
7708 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
7710 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

7758 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7759 This is also needed for porting to any host where GC_MARK_STACK is
7760 not GC_MAKE_GCPROS_NOOPS.
7761 (which_symbols): Use it.
7763 2011-11-07 Kenichi Handa <handa@m17n.org>

7785 (window_box_right, window_box_right_offset): Declare extern.
7786 Otherwise, these inline functions do not conform to C99 and
7787 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7788 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7789 * intervals.c (adjust_intervals_for_insertion)
7790 (adjust_intervals_for_deletion): Now extern, because otherwise the
7791 extern inline functions 'offset_intervals' couldn't refer to it.
7792 (static_offset_intervals): Remove.
7793 (offset_intervals): Rewrite using the old contents of
7794 static_offset_intervals. The old version didn't conform to C99
7795 because an extern inline function contained a reference to an
7796 identifier with static linkage.

8109 * editfns.c: Rewrite current-time-zone so that it invokes
8110 the equivalent of (format-time-string "%Z") to get the time zone name.
8111 This fixes a bug when the time zone name contains characters that
8112 need converting from the system time locale to Emacs internal format.
8113 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
8114 that patch fixed format-time-string to do the conversion, but
8115 I forgot to fix current-time-zone.
8116 (format_time_string): New function, containing most of
8117 what Fformat_time_string used to contain.
8118 (Fformat_time_string): Rewrite in terms of format_time_string.
8119 This doesn't change this function's behavior.
8120 (current-time-zone): Rewrite to use format_time_string.
8121 This fixes the bug reported by Michael Schierl in
8122 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
8123 Jason Rumney's 2007-06-07 change worked around this bug, but
8125 * systime.h (tzname, timezone): Remove no-longer-used declarations.
8127 2011-10-19 Eli Zaretskii <eliz@gnu.org>
8129 * xdisp.c (start_display): If the character at POS is displayed
8130 via a display vector, reset IT->current.dpvec_index to zero.
8131 (try_window_reusing_current_matrix): If a line ends in a display
8132 vector or the next line starts in a display vector, continue
8133 redrawing the window even though the character position of
8134 start_row was reached.
8137 2011-10-18 Chong Yidong <cyd@gnu.org>
8139 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
8140 with nobreak-char-display too.
8142 2011-10-18 Eli Zaretskii <eliz@gnu.org>
8144 Fix part 3 of bug#9771.
8145 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
8146 (bidi_resolve_neutral): Don't enter the expensive loop looking for
8147 non-neutral characters if the current character is a paragraph
8148 separator (a.k.a. Newline). This avoids running the same
8149 expensive loop twice, once when we consume the preceding newline
8150 and the other time when the line actually needs to be displayed.
8151 Avoid the loop when we see neutrals on the base embedding level
8152 following a character whose directionality is the same as the
8153 paragraph's. This avoids running the expensive loop when a line
8154 ends in a long sequence of neutrals, like control characters.
8155 Add assertion against STRONG_AL type. Slightly rearrange code
8156 that determines the type of a neutral given the first non-neutral
8158 (bidi_level_of_next_char): Set next_en_pos to zero when
8159 invalidating its info.
8161 2011-10-17 Eli Zaretskii <eliz@gnu.org>
8163 * xdisp.c (push_display_prop): Determine whether to record string
8164 or buffer position by IT->string, not by IT->method. Allow
8165 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
8166 (move_it_vertically_backward): Don't look for character position
8167 immediately after the newline when in a continuation line.
8170 2011-10-15 Martin Rudalics <rudalics@gmx.at>
8172 * window.c (coordinates_in_window): Rewrite and delabelize
8173 vertical border check. (Bug#5357) (Bug#9618)
8175 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
8177 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
8178 errors in XSetWindowBorder (bug#9310).
8180 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
8182 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
8183 avoid crash when xmalloc overrun checking is enabled.
8185 2011-10-13 Eli Zaretskii <eliz@gnu.org>
8187 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
8188 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
8189 cursor motion with <left> and <right> arrow keys.
8191 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
8192 some callers set that themselves.
8194 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8196 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
8197 display string and the previous row comes from the same string and
8198 is empty. (Bug#9739) (Bug#9738)
8200 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
8202 * doc.c (get_doc_string): Encode file name (bug#9735).
8204 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8206 * bidi.c (bidi_level_of_next_char):
8207 * xdisp.c (get_visually_first_element): Remove old incorrect
8208 comments regarding the Unicode Line Separator character.
8210 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
8212 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
8214 * alloc.c (Fgc_status): Do not access beyond zombies array
8215 boundary if nzombies > MAX_ZOMBIES.
8216 * alloc.c (dump_zombies): Add missing format specifier.
8218 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
8220 * xdisp.c (set_cursor_from_row): Simplify conditionals,
8221 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
8223 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
8224 Some packages use them to denote characters with modifiers.
8226 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
8228 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
8229 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
8230 matching a pp-number. Rename parameter var to var1.
8232 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
8234 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
8236 2011-10-08 Glenn Morris <rgm@gnu.org>
8238 * callint.c (Fcall_interactively): Give a more explicit error for the
8239 'c' case with a non-character input. (Bug#8479)
8241 2011-10-08 Eli Zaretskii <eliz@gnu.org>
8243 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
8245 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
8246 lines that are hscrolled on the left.
8248 * dispnew.c (buffer_posn_from_coords): Account for a possible
8249 presence of header-line. (Bug#4426)
8251 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
8253 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
8254 Don't advertise functionality which we discourage or doesn't work.
8256 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
8258 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
8259 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
8260 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
8261 this makes Emacs dump core during garbage collection on rare
8262 occasions. sizeof is obviously inferior to offsetof here, so
8263 stick with offsetof.
8264 (GC_POINTER_ALIGNMENT): New macro.
8265 (mark_memory): Omit 3rd (offset) arg; caller changed.
8266 Don't assume EMACS_INT alignment is the same as pointer alignment.
8268 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
8270 * keyboard.c (read_key_sequence_remapped): New var.
8271 (read_key_sequence): Compute remapping in the right buffer.
8272 (command_loop_1): Use read_key_sequence's remapping directly.
8274 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
8276 * dired.c (file_name_completion): Don't expand file name.
8277 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
8278 before checking file name handler.
8280 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
8281 they've been requested explicitly (bug#9591).
8283 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
8285 * keymap.c (Fsingle_key_description): Use make_specified_string
8286 instead of build_string to build string from push_key_description.
8289 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8291 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
8292 This fixes a Y2038 bug on 64-bit hosts.
8293 * buffer.c (reset_buffer):
8294 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
8295 (Fclear_buffer_auto_save_failure):
8296 Use 0, not -1, to represent an unset failure time, since time_t
8297 might not be signed.
8299 Remove dependency on glibc malloc internals.
8300 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8301 Move back here from lisp.h, but with their new implementations.
8302 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8303 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
8304 * charset.c (charset_table_init): New static var.
8305 (syms_of_charset): Use it instead of xmalloc. This removes a
8306 dependency on glibc malloc internals. See Eli Zaretskii's comment in
8307 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
8308 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8309 Move back to alloc.c.
8310 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8311 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
8313 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
8315 * nsterm.m (windowDidResize): Call x_set_window_size only when
8316 ns_in_resize is true. Otherwise set pixelwidth/height and
8317 call change_frame_size (Bug#9628).
8319 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8321 Port --enable-checking=all to Fedora 14 x86-64.
8322 * charset.c (syms_of_charset): Also account for glibc malloc's
8323 internal overhead when calculating the initial malloc maximum.
8325 Port --enable-checking=all to Fedora 14 x86.
8326 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8328 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
8329 (overrun_check_realloc, overrun_check_free):
8330 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
8331 That way, xmalloc returns a properly-aligned pointer even if
8332 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
8333 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
8334 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
8335 into account when calculating the initial malloc maximum.
8336 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8337 Move here from alloc.c, so that charset.c can use it too.
8338 Properly align; the old code wasn't right for common 32-bit hosts
8339 when configured with --enable-checking=all.
8340 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8341 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
8343 2011-09-29 Eli Zaretskii <eliz@gnu.org>
8345 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
8348 2011-09-28 Eli Zaretskii <eliz@gnu.org>
8350 * xdisp.c (compute_display_string_end): If there's no display
8351 string at CHARPOS, return -1.
8353 * bidi.c (bidi_fetch_char): When compute_display_string_end
8354 returns a negative value, treat the character as a normal
8355 character not covered by a display string. (Bug#9624)
8357 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
8359 * lread.c (Fread_from_string): Fix typo in docstring.
8361 2011-09-27 Eli Zaretskii <eliz@gnu.org>
8363 * xdisp.c (handle_invisible_prop): If invisible text ends on a
8364 newline, reseat the iterator instead of bidi-iterating there one
8365 character at a time. (Bug#9610)
8366 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
8367 TO_CHARPOS if the bidi iterator is at base embedding level.
8369 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
8371 * lread.c (readevalloop): Use correct code for NBSP.
8372 (read1): Likewise. (Bug#9608)
8374 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
8376 * dbusbind.c (Fdbus_register_signal): When service is not
8377 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
8379 2011-09-25 Glenn Morris <rgm@gnu.org>
8381 * buffer.c (truncate-lines): Doc fix.
8383 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
8385 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
8386 (Fset_window_next_buffers): Doc fix.
8388 2011-09-24 Glenn Morris <rgm@gnu.org>
8390 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
8392 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
8394 Fix minor problems found by static checking.
8395 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
8396 * indent.c (Fvertical_motion): Fix == vs = typo.
8398 2011-09-24 Eli Zaretskii <eliz@gnu.org>
8400 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
8401 Default value is now t. Doc fix.
8403 * indent.c (Fvertical_motion): Compute and apply the overshoot
8404 logic when moving up, not only when moving down. Fix the
8405 confusing name and values of the it_overshoot_expected variable;
8406 logic changes accordingly. (Bug#9254) (Bug#9549)
8408 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
8409 CHARPOS is covered by a display string which includes newlines.
8410 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
8411 is covered by a display string with embedded newlines.
8413 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
8415 * dbusbind.c (Fdbus_register_signal): Add match rule to
8416 Vdbus_registered_objects_table. (Bug#9581)
8417 (Fdbus_register_method, Vdbus_registered_objects_table):
8420 2011-09-24 Jim Meyering <meyering@redhat.com>
8422 do not ignore write error for any output size
8423 The previous change was incomplete.
8424 While it makes emacs --batch detect the vast majority of stdout
8425 write failures, errors were still ignored whenever the output size is
8426 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
8427 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
8428 && echo FAIL: ignored write error
8429 FAIL: ignored write error
8430 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
8431 && echo FAIL: ignored write error
8432 FAIL: ignored write error
8433 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
8435 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
8437 * emacs.c (Fkill_emacs): In noninteractive mode exit
8438 non-successfully if a write error occurred on stdout. (Bug#9574)
8440 2011-09-21 Eli Zaretskii <eliz@gnu.org>
8442 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
8445 * dispextern.h (struct it): Update the comment documenting what
8448 2011-09-20 Eli Zaretskii <eliz@gnu.org>
8450 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
8451 a display string, extend search for cursor position to end of row.
8452 (find_row_edges): If the row ends in a newline from a display
8453 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
8454 Handle the case of a display string with multiple newlines.
8455 (Fcurrent_bidi_paragraph_direction): Fix search for previous
8456 non-empty line. Fixes confusing cursor motion with arrow keys at
8457 the beginning of a line that starts with whitespace.
8459 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8461 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
8464 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
8466 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
8469 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8471 * xdisp.c (display_line): Record maximum and minimum buffer
8472 positions even if no glyphs were produced (e.g., by a zero-width
8473 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
8474 buffer positions that will be removed from the glyph row because
8476 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
8477 column is beyond frame width: don't subtract 1 "pixel" when
8478 computing width of the stretch.
8479 (reseat_at_next_visible_line_start): Undo the change made on
8480 2011-09-17 that saved paragraph information and restored it after
8481 the call to `reseat'. (Bug#9545)
8483 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8485 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
8486 and turn window cursor on if cleared (Bug#9415).
8488 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
8490 * search.c (boyer_moore): Take unibyte characters from pattern
8491 literally. (Bug#9458)

8497 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
8499 Fix minor problem found by static checking.
8500 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8501 initialized, to pacify gcc -Wuninitialized.
8503 * fileio.c: Report proper errno when syscall falls.
8504 (Finsert_file_contents): Save and restore errno,
8505 so that report_file_error outputs the correct diagnostic.
8506 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8508 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8510 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8512 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8514 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8515 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8517 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8519 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8520 about the current paragraph and restore it after the call to reseat.
8522 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8523 (bidi_find_paragraph_start): Search back for paragraph beginning
8524 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8525 (bidi_move_to_visually_next): Only trigger paragraph-related
8526 computations when the last character is a newline or at EOB, not
8527 just any NEUTRAL_B. (Bug#9470)
8529 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8530 truncated lines if point is covered by a display string. (Bug#9524)
8532 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8534 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8535 (cons_to_x_long): New function.
8536 (lisp_data_to_selection_data): Use it. Correct the test for
8537 short-versus-long data; it was negated. Break out of vector
8538 loop, for efficiency, when a long datum is discovered.
8540 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8542 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8544 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8546 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8547 GCC PR/17406) by declaring this function with external scope.
8549 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8551 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

8568 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8570 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8571 This occurs when processing a multibyte format.
8572 Problem reported by Wolfgang Jenker.
8574 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8576 * xdisp.c (try_cursor_movement): Only check for exact match if
8577 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8579 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8581 Remove unused external symbols.
8582 * dispextern.h (calc_pixel_width_or_height): Remove decl.

8584 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
8585 * indent.c (check_display_width):
8586 * w32term.c: Fix comment to match code.
8587 * xterm.c, xterm.h (x_catching_errors): Remove.
8589 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8591 * xselect.c: Use signed conversions more consistently (Bug#9498).
8592 (selection_data_to_lisp_data): Assume incoming selection data are
8593 signed integers, not unsigned. This is to be consistent with
8594 outgoing selection data, which was modified to use signed integers
8595 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8596 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8597 expects long, not unsigned long.
8599 2011-09-14 Eli Zaretskii <eliz@gnu.org>
8601 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
8602 computation of loop end. Reported by Johan Bockgård
8605 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
8607 * frame.c (Fother_visible_frames_p): Function deleted.
8609 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8611 * indent.c (compute_motion): Process display vector front to back
8612 rather than the other way around. (Bug#2496)
8614 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8616 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8618 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8620 * minibuf.c (Fread_from_minibuffer): Doc fix.
8622 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8624 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8625 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8627 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8629 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8630 value for non-existent files.
8632 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8634 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8635 set its "size" to -1. This will set the modtime_size field of
8636 the corresponding buffer to -1, which is what
8637 verify-visited-file-modtime expects for files that do not exist.
8640 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8642 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8644 * lisp.h: ... from here. push_key_description is no longer
8645 defined in keyboard.c, so its declaration should not be in
8646 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8647 logically belongs with push_key_description.
8649 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8651 * buffer.h: Include <sys/types.h> instead of <time.h>.
8652 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8653 Problem reported by Herbert J. Skuhra.
8655 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8657 * xml.c (parse_region): Make the parsing work for
8658 non-comment-starting XML files again (bug#9144).
8660 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8662 * image.c (gif_load): Fix calculation of bottom and right corner.
8665 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8667 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8668 redisplay in small windows.
8670 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8672 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8674 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8676 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8677 Operate on live windows only.
8679 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8681 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8683 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8685 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8686 only under bidi iteration.
8688 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8690 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8692 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8694 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8695 Without this fix, the command to link temacs failed due to an
8696 undefined symbol __builtin_isnan. This is because
8697 /usr/include/iso/math_c99.h #defines isnan(x) to
8698 __builtin_isnan(x), but the bundled gcc, which identifies itself
8699 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8701 * floatfns.c (isnan): #undef, and then #define to a clone of
8703 (Fisnan): Always define, since it's always available now.
8704 (syms_of_floatfns): Always define isnan at the Lisp level.
8706 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8708 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8710 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8712 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8713 The previous code assumed that file offsets (off_t values) fit in
8714 EMACS_INT variables, which is not true on typical 32-bit hosts.
8715 The code messed up by falsely reporting buffer overflow in cases
8716 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8717 when "big" contains more than 2**29 bytes, even though this
8718 inserts just one byte and does not overflow the buffer.
8719 (Finsert_file_contents): Store file offsets as off_t
8720 values, not as EMACS_INT values. Check for overflow when
8721 converting between EMACS_INT and off_t. When checking for
8722 buffer overflow or for overlap, take the offsets into account.
8723 Don't use EMACS_INT for small values where int suffices.
8724 When checking for overlap, fix a typo: ZV was used where
8725 ZV_BYTE was intended.
8726 (Fwrite_region): Don't assume off_t fits into 'long'.
8727 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8729 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8731 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8733 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8735 sprintf-related integer and memory overflow issues (Bug#9412).
8737 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8738 (esprintf, exprintf, evxprintf): New functions.
8739 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8740 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8741 (modify_event_symbol): Do not assume that the length of
8742 name_alist_or_stem is safe to alloca and fits in int.
8743 (Fexecute_extended_command): Likewise for function name and binding.
8744 (Frecursion_depth): Wrap around reliably on integer overflow.
8745 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8746 since some callers pass EMACS_INT values.
8747 (Fsingle_key_description): Don't crash if symbol name contains more
8748 than MAX_ALLOCA bytes.
8749 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8750 (get_minibuffer): Arg is now EMACS_INT, not int.
8751 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8752 (esprintf, exprintf, evxprintf): New decls.
8753 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8755 * dbusbind.c (signature_cat): New function.
8756 (xd_signature, Fdbus_register_signal):
8757 Do not overrun buffer; instead, report string overflow.
8759 * dispnew.c (add_window_display_history): Don't overrun buffer.
8760 Truncate instead; this is OK since it's just a log.
8762 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8763 even if the time zone offset is outlandishly large.
8764 Don't mishandle offset == INT_MIN.
8766 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8767 when creating daemon; the previous buffer-overflow check was incorrect.
8769 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8770 which has the guts of the old verror function.
8772 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8773 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8775 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8776 (font_unparse_xlfd): Don't blindly alloca long strings.
8777 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8778 fits in int, when using sprintf. Use single snprintf to count
8779 length of string rather than counting it via multiple sprintfs;
8780 that's simpler and more reliable.
8781 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8782 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8783 sprintf, in case result does not fit in int.
8785 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8786 (fontset_from_font): Print it.
8788 * frame.c (tty_frame_count): Now printmax_t, not int.
8789 (make_terminal_frame, set_term_frame_name): Print it.
8790 (x_report_frame_params): In X, window IDs are unsigned long,
8791 not signed long, so print them as unsigned.
8792 (validate_x_resource_name): Check for implausibly long names,
8793 and don't assume name length fits in 'int'.
8794 (x_get_resource_string): Don't blindly alloca invocation name;
8795 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8798 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8799 (xg_check_special_colors, xg_set_geometry):
8800 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8802 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8803 Use esprintf, not sprintf, in case result does not fit in int.
8805 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8806 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8807 it as a large positive number.
8808 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8809 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8811 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8812 in case result does not fit in int.
8814 * print.c (float_to_string): Detect width overflow more reliably.
8815 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8816 buffer overrun. Don't assume list length fits in 'int'. Treat
8817 print length of 0 as 0, not as infinity; to be consistent with other
8818 uses of print length in this function. Don't overflow print length
8819 index. Don't assume hash table size fits in 'long', or that
8820 vectorlike size fits in 'unsigned long'.
8822 * process.c (make_process): Use printmax_t, not int, to format
8823 process-name gensyms.
8825 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8827 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8828 to avoid potential buffer overrun.
8830 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8831 if X resource line is longer than 512 bytes.
8833 * xfns.c (x_window): Make sprintf buffer a bit bigger
8834 to avoid potential buffer overrun.
8836 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8838 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8840 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8842 Integer overflow fixes for scrolling, etc.
8843 Without these, Emacs silently mishandles large integers sometimes.
8844 For example, "C-u 4294967297 M-x recenter" was treated as if
8845 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8847 * xdisp.c (try_window_id): Check Emacs fixnum range before
8848 converting to 'int'.
8850 * window.c (window_scroll_line_based, Frecenter):
8851 Check that an Emacs fixnum is in range before assigning it to 'int'.
8852 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8853 values converted from Emacs fixnums.
8854 (Frecenter): Don't wrap around a line count if it is out of 'int'
8855 range; instead, treat it as an extreme value.
8856 (Fset_window_configuration, compare_window_configurations):
8857 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8859 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8860 that can exceed INT_MAX. Check that EMACS_INT value is in range
8861 before assigning it to the (possibly-narrower) index.
8862 (match_limit): Don't assume that a fixnum can fit in 'int'.
8864 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8867 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8868 (Fvertical_motion): Don't wrap around LINES values that don't fit
8869 in 'int'. Instead, treat them as extreme values. This is good
8870 enough for windows, which can't have more than INT_MAX lines anyway.
8872 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8874 * Require libxml/parser.h to avoid compilation warning.
8876 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8878 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8879 since this reportedly can destroy thread storage.
8881 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8883 * syntax.c (find_defun_start): Update all cache variables if
8884 exiting early (Bug#9401).
8886 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8888 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8890 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8891 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8892 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8894 * term.c (tty_append_glyph): New function.
8895 (produce_stretch_glyph): Static function and its prototype deleted.
8897 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8900 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8902 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8903 when checking :margin (Bug#9390).
8904 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8905 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8906 so that the name doesn't mislead. All uses changed.
8908 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8910 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8913 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8915 * xdisp.c (move_it_to): Don't bail out early when reaching
8916 position beyond to_charpos, if we are scanning backwards.
8917 (move_it_vertically_backward): When DY == 0, make sure we get to
8918 the first character in the line after the newline.
8920 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8922 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8923 (ccl_driver): Do not generate an out-of-range pointer.
8924 (Fccl_execute_on_string): Remove unnecessary check for
8925 integer overflow, noted by Stefan Monnier in
8926 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8927 Remove a FIXME that didn't need fixing.
8928 Simplify the newly-introduced buffer reallocation code.
8930 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8932 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8934 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8936 Integer and memory overflow issues (Bug#9196).
8938 * doc.c (get_doc_string): Rework so that
8939 get_doc_string_buffer_size is the actual buffer size, rather than
8940 being 1 less than the actual buffer size; this makes xpalloc more
8943 * image.c (x_allocate_bitmap_record, cache_image):
8944 * xselect.c (Fx_register_dnd_atom):
8945 Simplify previous changes by using xpalloc.
8947 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8948 since either will do and ptrdiff_t is convenient with xpalloc.
8950 * charset.c (charset_table_size)
8951 (struct charset_sort_data.priority): Now ptrdiff_t.
8952 (charset_compare): Don't overflow if priorities differ greatly.
8953 (Fsort_charsets): Don't assume list length fits in int.
8954 Check for size-calculation overflow when allocating sort data.
8955 (syms_of_charset): Allocate an initial charset table that is
8956 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8958 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8960 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8961 The actual value is always <= INT_MAX, and leaving it unsigned made
8962 overflow checking harder.
8964 * dispextern.h (struct glyph_matrix.rows_allocated)
8965 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8966 with xpalloc. The values are still always <= INT_MAX.
8968 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8970 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8971 (SAFE_NALLOCA): New macro.
8973 * region-cache.c (struct boundary.pos, find_cache_boundary)
8974 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8975 (set_cache_region, invalidate_region_cache)
8976 (revalidate_region_cache, know_region_cache, region_cache_forward)
8977 (region_cache_backward, pp_cache):
8978 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8979 so that ptrdiff_t * can be passed to xpalloc.
8980 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8981 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8982 (pp_cache): Don't assume cache_len fits in int.
8983 * region-cache.h: Adjust extern decls to match.
8985 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8986 EMACS_INT, since either will do, for xpalloc.
8988 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8989 (xnmalloc, xnrealloc, xpalloc): New functions.
8991 * bidi.c (bidi_shelve_header_size): New constant.
8992 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8993 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8995 * bidi.c (bidi_cache_shrink):
8996 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8998 Don't update size of array until after memory allocation succeeds,
8999 because xmalloc/xrealloc may not return.
9000 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
9001 now that we have proper integer overflow checking.
9002 (record_overlay_string, overlay_strings): Catch overflows when
9003 calculating size of overlay_str_buf.
9005 * callproc.c (Fcall_process): Check for size overflow when
9006 calculating size of args2.
9007 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
9008 Normally we prefer signed values, but sticking with ptrdiff_t would
9009 require adding more-complicated checks.
9011 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
9012 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
9013 Redo buffer-overflow calculations to avoid integer overflow.
9014 Add a FIXME comment where memory seems to be over-allocated.
9016 * character.c (Fstring): Check for size-calculation overflow.
9018 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
9019 unnecessary integer overflow. Check for size overflow.
9020 (encode_coding_object): Don't update size until xmalloc succeeds.
9022 * composite.c (get_composition_id): Check for overflow in glyph
9023 length calculations.
9025 Integer and memory overflow fixes for display code.
9026 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
9027 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
9028 (scrolling_window): Check for overflow in size calculations.
9029 (line_draw_cost, realloc_glyph_pool, add_row_entry):
9030 Don't assume glyph table len fits in int.
9031 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
9032 (row_table_size): Now ptrdiff_t, not int.
9033 (scrolling_window): Avoid overflow in size calculations.
9034 Don't update size until allocation succeeds.
9035 * fns.c (concat): Check for overflow in size calculations.
9036 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
9037 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
9038 (NEXT_ALMOST_PRIME_LIMIT): New constant.
9040 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
9041 (get_doc_string): Check for size calculation overflow.
9042 Don't update size until allocation succeeds.
9043 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
9044 EMACS_INT, where ptrdiff_t will do.
9045 (Fsubstitute_command_keys): Check for string overflow.
9047 * editfns.c (set_time_zone_rule): Don't assume environment length
9049 (message_length): Now ptrdiff_t, not int.
9050 (Fmessage_box): Don't update size until allocation succeeds.
9051 Don't assume message length fits in int.
9052 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
9054 * emacs.c (main): Do not reallocate argv, since there is a null at
9055 the end that can be overwritten, and this way there's no need to
9056 worry about size-calculation overflow.
9057 (sort_args): Check for size-calculation overflow.
9059 * eval.c (init_eval_once, grow_specpdl): Don't update size until
9061 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.

9174 (Fx_change_window_property): Use ptrdiff_t, not int, to count
9175 sizes, since they can exceed INT_MAX in size. Check for size

9185 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
9186 (X_LONG_MIN): New macros.
9187 Use them to make the following changes clearer.
9188 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
9189 This change doesn't affect the value now, but it may help remind
9190 future maintainers not to raise the value too much later.
9191 (SELECTION_QUANTUM): Remove, replacing with ...
9192 (selection_quantum): ... new function, which avoids overflow.
9194 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

9212 Don't store size until memory allocation succeeds.
9213 (x_get_window_property): Plug memory leak on memory exhaustion.
9214 Don't double-block input; malloc is safe here. Don't assume 2**34
9215 - 4 fits in unsigned long. Add an xassert to check
9216 XGetWindowProperty overflow. Be more careful about overflow
9217 calculations, and distinguish size from memory overflow better.

9223 in the range -65535 through -1 fit in an X unsigned short.
9224 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
9225 result parameters unless successful. Rely on cons_to_unsigned
9226 to report problems with elements; the old code wasn't right anyway.
9227 (x_check_property_data): Check for int overflow; we cannot use
9228 a wider type due to X limits.

9261 * lisp.h (hash_lookup, hash_put):
9262 * minibuf.c (Ftest_completion):
9263 Use ptrdiff_t for hash table indexes, not int (which is too
9264 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
9265 32-bit --with-wide-int hosts).

9298 (x_send_scroll_bar_event): Likewise. Check that the size does not
9299 exceed limits imposed by XClientMessageEvent, as well as the usual
9300 ptrdiff_t and size_t limits.
9302 * keyboard.c: Overflow, signedness and related fixes.
9303 (make_lispy_movement): Use same integer type in forward decl
9304 that is used in the definition.
9305 (read_key_sequence, keyremap_step):
9306 Change bufsize argument back to int, undoing my 2011-03-30 change.
9307 We prefer signed types, and int is wide enough here.
9308 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
9309 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
9310 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
9311 length, not size_t. Use ptrdiff_t for index, not int.
9312 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
9313 possibility of integer overflow.

9341 Prefer int to unsigned where either will do.
9342 (tiff_handler): New function, combining the cores of the
9343 old tiff_error_handler and tiff_warning_handler.
9344 This function is rewritten to use vsnprintf and thereby avoid
9345 stack buffer overflows. It uses only the features of vsnprintf
9346 that are common to both POSIX and native Microsoft.
9347 (tiff_error_handler, tiff_warning_handler): Use it.
9348 (tiff_load, gif_load, imagemagick_load_image):
9349 Don't assume :index value fits in 'int'.
9350 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

9352 the integer types that MagickCropImage accepts. Don't assume
9353 Vimagemagick_render_type has a nonnegative value. Don't assume
9354 size_t fits in 'long'.
9355 (gs_load): Use printmax_t to print the widest integers possible.

9373 accurately, and prefer exact match for point under bidi.
9374 Don't advance `row' beyond the last row of the window.
9376 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
9377 into disp_prop; all users changed.
9379 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

9395 positioning on the newline at EOL of R2L text within L2R
9396 paragraph, and vice versa.
9397 (try_cursor_movement): Check continued rows, in addition to
9398 continuation rows. Fixes unwarranted scroll when point enters a
9399 continued line of R2L text within an L2R paragraph, or vice versa.
9400 (cursor_row_p): Consider the case of point being equal to
9401 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
9402 from the end of a short line to the beginning of a continued line
9403 of R2L text within L2R paragraph.

9430 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
9431 instead of CHAR_TO_BYTE. Fixes a crash when a completion
9432 candidate is selected by the mouse, and that candidate has a
9433 composed character under the mouse.
9435 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
9436 coordinates reported by pos-visible-in-window-p for a composed

9447 composed buffer positions.
9449 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
9451 * image.c (gif_load): Don't assume that each subimage has the same
9452 dimensions as the base image. Handle disposal method that is
9453 "undefined" by the gif spec (Bug#9335).
9455 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
9457 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

9462 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
9463 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
9464 from an Org mode buffer to a Speedbar frame.
9466 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
9467 a composition, take its buffer position from IT->cmp_it.charpos.
9468 Fixes cursor positioning at the beginning of a line that begins
9469 with a composed character.
9471 2011-08-18 Eli Zaretskii <eliz@gnu.org>
9473 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
9474 character bidirectional type, use STRONG_L instead. Fixes crashes
9475 in a buffer produced by `describe-categories'.
9477 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
9478 members before the level stack, so they would be saved and
9479 restored when copying iterator state. Fixes incorrect reordering
9480 around TABs covered by display properties.
9482 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

9520 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
9521 requests to realloc storage in the static heap.
9523 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
9525 * bidi.c (bidi_initialize): Remove unused local.
9527 2011-08-15 Eli Zaretskii <eliz@gnu.org>
9530 * biditype.h: Remove file.
9531 * makefile.w32-in ($(BLD)/bidi.$(O)):
9532 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
9534 * dispextern.h: Fix a typo in the comment to bidi_type_t.
9536 * chartab.c: Improve commentary for the uniprop_table API.
9538 * bidi.c (bidi_paragraph_init): Support zero value of
9539 bidi_ignore_explicit_marks_for_paragraph_level.
9540 (bidi_initialize): Use uniprop_table instead of including
9541 biditype.h and bidimirror.h.
9543 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
9544 coordinates of the iterator when restoring from ppos_it.
9547 2011-08-14 Kenichi Handa <handa@m17n.org>
9549 * process.c (create_process): Call setup_process_coding_systems
9550 after the pid of the process is set to -1 (Bug#8162).
9552 2011-08-14 Eli Zaretskii <eliz@gnu.org>
9554 * xdisp.c (move_it_in_display_line_to): Don't invoke
9555 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
9556 ppos_it. Fixes vertical cursor motion when line beginning is
9557 covered by an image. (Bug#9296)
9559 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
9561 * nsterm.h (ns_run_ascript): Declare.
9562 (NSAPP_DATA2_RUNASSCRIPT): Define.
9564 * nsfns.m (as_script, as_result, as_status): New static variables.
9565 (ns_run_ascript): New function.
9566 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
9567 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
9568 the event loop. Get status from as_status (Bug#7276).
9570 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9571 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9572 the event loop (Bug#7276).
9574 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
9576 * gnutls.c (QCgnutls_bootprop_priority)
9577 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
9578 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
9579 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
9580 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
9581 (QCgnutls_bootprop_verify_hostname_error)
9582 (QCgnutls_bootprop_callbacks_verify): Rename from
9583 Qgnutls_bootprop_..., all uses changed.
9585 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
9588 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
9590 * xfaces.c (Qframe_set_background_mode): Now static.
9591 * dispextern.h (Qframe_set_background_mode): Remove decl.
9593 * process.c (Fnetwork_interface_info): Declare local only if needed.
9595 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9597 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9598 (Fnetwork_interface_list): Allocate in increments of bytes instead
9599 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9600 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9602 (struct ifflag_def): notrailers is smart on OSX.
9603 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9604 Get hardware address with getifaddrs if available.
9606 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9608 * xdisp.c (iterate_out_of_display_property): xassert that
9609 IT->position is set to within IT->object's boundaries. Break from
9610 the loop as soon as EOB is reached; avoids infloops in redisplay
9611 when IT->position is set up wrongly due to some bug.
9612 Set IT->current to match the bidi iterator unconditionally.
9613 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9614 entry. Force push_it to save on the stack the current
9615 buffer/string position, to be restored by pop_it. Fix flags in
9616 the iterator structure wrt the object coming from a display
9617 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9618 properties. (Bug#9284)
9620 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9622 * fontset.c (fontset_get_font_group): Add proper type checks.
9625 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9627 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
9628 and LC_VERSION_MIN_MACOSX.
9629 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9630 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9632 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9634 * xdisp.c (forward_to_next_line_start): Allow to use the
9635 no-display-properties-and-no-overlays under bidi display.
9636 Set disp_pos in the bidi iterator to avoid searches for display
9637 properties and overlays.
9639 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9641 * editfns.c (Fset_time_zone_rule): Document relationship with the
9644 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9645 the font entity extracted from the cache (Bug#8109).
9647 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9649 * composite.c (autocmp_chars): Don't reset point. That is done by
9650 restore_point_unwind (Bug#5984).
9652 2011-08-07 Juri Linkov <juri@jurta.org>
9654 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9655 to show the arg `TIME' instead of `TIMEVAL'.
9657 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9659 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9660 display property strides EOL and includes a newline, as in
9661 longlines-mode. (Bug#9254)
9662 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9663 word-wrap under bidirectional display. (Bug#9224)
9665 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9666 is non-zero, even if the data buffer is NULL. Fixes a crash in
9667 vertical-motion with longlines-mode. (Bug#9254)
9669 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9671 * bidi.c <bidi_cache_total_alloc>: Now static.
9672 (bidi_initialize): Initialize bidi_cache_total_alloc.
9674 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9677 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9678 amount allocated this far in `bidi_cache_total_alloc'.
9679 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9680 non-zero, only free the data buffer without restoring the cache
9681 contents. All callers changed.
9683 * dispextern.h (bidi_unshelve_cache): Update prototype.
9685 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9686 (move_it_in_display_line, move_it_to)
9687 (move_it_vertically_backward, move_it_by_lines): Replace the call
9688 to xfree to an equivalent call to bidi_unshelve_cache.
9689 (move_it_in_display_line_to): Fix logic of returning
9690 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9692 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9694 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9695 came from a string character with a `cursor' property. (Bug#9229)
9697 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9699 * Makefile.in (LIB_PTHREAD): New variable.
9700 (LIBES): Add LIB_PTHREAD (Bug#9216).
9702 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9703 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9705 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9707 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9709 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9711 * xterm.c (x_find_topmost_parent): New function.
9712 (x_set_frame_alpha): Find topmost parent window with
9713 x_find_topmost_parent and set the property there also (bug#9181).
9714 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9716 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9718 * callproc.c (Fcall_process): Avoid vfork clobbering
9719 the local vars buffer, coding_systems, current_dir.
9721 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9723 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9725 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9727 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9728 so that it is not optimized away.
9730 * xdisp.c (compute_display_string_pos): Remove unused local.
9732 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9734 Fix slow cursor motion and scrolling in large buffers with
9735 selective display, like Org Mode buffers. (Bug#9218)
9737 * dispextern.h (struct bidi_it): New member disp_prop_p.
9739 * xdisp.c: Remove one-slot cache of display string positions.
9740 (compute_display_string_pos): Accept an additional argument
9741 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9742 for a display string or property. If found, set DISP_PROP_P
9745 * bidi.c (bidi_fetch_char): Accept an additional argument
9746 DISP_PROP_P, and pass it to compute_display_string_pos.
9747 Only handle text covered by a display string if DISP_PROP_P is returned
9748 non-zero. All callers of bidi_fetch_char changed.
9750 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9752 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9754 2010-12-03 Don March <don@ohspite.net>
9756 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9757 last character M-[char] is translated to ESC [char] (bug#7541).
9759 2011-08-02 Kenichi Handa <handa@m17n.org>
9761 * lisp.h (uniprop_table): Extern it.
9763 * chartab.c (uniprop_table): Make it non-static.
9765 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9767 * xdisp.c (forward_to_next_line_start): Accept additional argument
9768 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9770 (reseat_at_next_visible_line_start): Use the bidi iterator state
9771 returned by forward_to_next_line_start to restore the state of
9772 it->bidi_it after backing up to previous newline. (Bug#9212)
9774 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9776 * regex.c (re_comp): Protoize.
9777 (re_exec): Fix return type.
9778 (regexec): Fix type of `ret'. (Bug#9203)
9780 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9782 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9783 This is needed if max-image-size is a floating-point number.
9785 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9787 * print.c (print_object): Print empty symbol as ##.
9789 * lread.c (read1): Read ## as empty symbol.
9791 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9793 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9794 setting frame foreground color (Bug#9175).
9795 (x_set_background_color): Likewise.
9797 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9798 contents (Bug#9176).
9799 (EmacsTooltip -init): Remove bezels and add shadows to
9802 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9803 or scroll bar (Bug#8470).
9805 * nsfont.m (nsfont_open): Remove assignment to voffset and
9806 unnecessary vars hshink, expand, hd, full_height, min_height.
9807 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9809 * nsterm.h (nsfont_info): Remove voffset field.
9811 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9813 Implement strike-through and overline on NextStep (Bug#8863).
9815 * nsfont.m (nsfont_open): Use underline position provided by font,
9816 instead of hard-coded value of 2.
9817 (nsfont_draw): Call ns_draw_text_decoration instead.
9819 * nsterm.h: Add declaration for ns_draw_text_decoration.
9821 * nsterm.m (ns_draw_text_decoration): New function for drawing
9822 underline, overline, and strike-through.
9823 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9824 ns_draw_text_decoration. Change treatment of cursor drawing to
9825 accommodate underlining, etc.
9827 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9829 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9832 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9834 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9835 Without this fix, if a signal arrives just after memory fills up,
9836 'malloc' might be invoked reentrantly.
9838 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9839 In other words, assume that every image size is allowed, on non-X
9840 hosts. This assumption is probably wrong, but it lets Emacs compile.
9842 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9844 * regex.c (re_iswctype): Convert return values to boolean.
9846 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9848 * xdisp.c (compute_display_string_pos): Don't use cached display
9849 string position if the buffer had its restriction changed.
9852 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9854 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9856 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9858 Integer signedness and overflow and related fixes. (Bug#9079)
9860 * bidi.c: Integer size and overflow fixes.
9861 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9862 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9863 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9864 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9865 (bidi_find_other_level_edge):
9866 Use ptrdiff_t instead of EMACS_INT where either will do.
9867 This works better on 32-bit hosts configured --with-wide-int.
9868 (bidi_cache_ensure_space): Check for size-calculation overflow.
9869 Use % rather than repeated addition, for better worst-case speed.
9870 Don't set bidi_cache_size until after xrealloc returns, because it
9872 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9873 (bidi_cache_ensure_space): Also check that the bidi cache size
9874 does not exceed that of the largest Lisp string or buffer. See Eli
9875 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9877 * alloc.c (__malloc_size_t): Remove.
9878 All uses replaced by size_t. See Andreas Schwab's note
9879 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9881 * image.c: Improve checking for integer overflow.
9882 (check_image_size): Assume that f is nonnull, since
9883 it is always nonnull in practice. This is one less thing to
9884 worry about when checking for integer overflow later.
9885 (x_check_image_size): New function, which checks for integer
9886 overflow issues inside X.
9887 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9888 This removes the need for a memory_full check.
9889 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9890 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9891 (xbm_read_bitmap_data): Change locals back to 'int', since
9892 their values must fit in 'int'.
9893 (xpm_load_image, png_load, tiff_load):
9894 Invoke x_create_x_image_and_pixmap earlier,
9895 to avoid much needless work if the image is too large.
9896 (tiff_load): Treat overly large images as if
9897 x_create_x_image_and_pixmap failed, not as malloc failures.
9898 (gs_load): Use x_check_image_size.
9900 * gtkutil.c: Omit integer casts.
9901 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9902 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9904 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9906 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9907 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9908 would wrongly return t on a 64-bit host.
9910 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9911 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9912 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9913 and therefore cause GCC to emit a bogus diagnostic in some cases.
9915 * image.c: Integer signedness and overflow and related fixes.
9916 This is not an exhaustive set of fixes, but it's time to
9917 record what I've got.
9918 (lookup_pixel_color, check_image_size): Remove redundant decls.
9919 (check_image_size): Don't assume that arbitrary EMACS_INT values
9920 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9921 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9922 (tiff_load, imagemagick_load_image):
9923 Check for overflow in size calculations.
9924 (x_create_x_image_and_pixmap): Remove unnecessary test for
9925 xmalloc returning NULL; that can't happen.
9926 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9927 (xpm_color_bucket): Use better integer hashing function.
9928 (xpm_cache_color): Don't possibly over-allocate memory.
9929 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9930 (gif_memory_source):
9931 Use ptrdiff_t, not int or size_t, to record sizes.
9932 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9933 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9934 either works, as we prefer signed integers.
9935 (tiff_read_from_memory, tiff_write_from_memory):
9936 Return tsize_t, not size_t, since that's what the TIFF API wants.
9937 (tiff_read_from_memory): Don't fail simply because the read would
9938 go past EOF; instead, return a short read.
9939 (tiff_load): Omit no-longer-needed casts.
9940 (Fimagemagick_types): Don't assume size fits into 'int'.
9942 Improve hashing quality when configured --with-wide-int.
9943 * fns.c (hash_string): New function, taken from sxhash_string.
9944 Do not discard information about ASCII character case; this
9945 discarding is no longer needed.
9946 (sxhash-string): Use it. Change sig to match it. Caller changed.
9947 * lisp.h: Declare it.
9948 * lread.c (hash_string): Remove, since we now use fns.c's version.
9949 The fns.c version returns a wider integer if --with-wide-int is
9950 specified, so this should help the quality of the hashing a bit.
9952 * emacs.c: Integer overflow minor fix.
9953 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9954 Define only if GNU_LINUX.
9955 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9957 * dispnew.c: Integer signedness and overflow fixes.
9958 Remove unnecessary forward decls, that were a maintenance hassle.
9959 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9961 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9962 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9963 (prepare_desired_row, line_draw_cost):
9964 Use int, not unsigned, where either works.
9965 (save_current_matrix, restore_current_matrix):
9966 Use ptrdiff_t, not size_t, where either works.
9967 (init_display): Check for overflow more accurately, and without
9968 relying on undefined behavior.
9970 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9971 Remove, replacing with the new symbols in lisp.h. All uses changed.
9972 * fileio.c (make_temp_name):
9973 * filelock.c (lock_file_1, lock_file):
9974 * xdisp.c (message_dolog):
9975 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9976 Use pMd etc. instead.
9977 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9978 replacing the pWIDE etc. symbols removed from editfns.c.
9980 * keyboard.h (num_input_events): Now uintmax_t.
9981 This is (very slightly) less likely to mess up due to wraparound.
9984 * buffer.c: Integer signedness fixes.
9985 (alloc_buffer_text, enlarge_buffer_text):
9986 Use ptrdiff_t rather than size_t when either will do, as we prefer
9989 * alloc.c: Integer signedness and overflow fixes.
9990 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9991 (__malloc_size_t): Default to size_t, not to int.
9992 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9993 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9994 Prefer ptrdiff_t to size_t when either would do, as we prefer
9996 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9997 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9998 Now const. Initialize with values that are in range even if char
10000 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
10001 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
10002 These functions do the right thing with sizes > 2**32.
10003 (check_depth): Now ptrdiff_t, not int.
10004 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
10005 Adjust to new way of storing sizes. Check for size overflow bugs
10007 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
10008 slightly wrong anyway, as it missed one instance of
10009 XMALLOC_OVERRUN_CHECK_OVERHEAD.
10010 (refill_memory_reserve): Omit needless cast to size_t.
10011 (mark_object_loop_halt): Mark as externally visible.
10013 * xselect.c: Integer signedness and overflow fixes.
10014 (Fx_register_dnd_atom, x_handle_dnd_message):
10015 Use ptrdiff_t, not size_t, since we prefer signed.
10016 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
10017 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
10018 x_dnd_atoms_size and x_dnd_atoms_length.
10020 * doprnt.c: Prefer signed to unsigned when either works.
10022 * doprnt.c (doprnt):
10024 * xdisp.c (vmessage):
10025 Use ptrdiff_t, not size_t, when using or implementing doprnt,
10026 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
10027 prefer signed arithmetic to avoid comparison confusion.
10028 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
10029 but is a bit tricky.
10031 Assume freestanding C89 headers, string.h, stdlib.h.
10032 * data.c, doprnt.c, floatfns.c, print.c:
10033 Include float.h unconditionally.
10034 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10035 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10036 * regex.c: Likewise for stddef.h, string.h.
10037 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10038 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10039 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10040 (STDC_HEADERS): Remove obsolete defines.
10041 * sysdep.c: Include limits.h unconditionally.
10043 Assume support for memcmp, memcpy, memmove, memset.
10044 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10045 * regex.c (memcmp, memcpy):
10046 Remove; we assume C89 now.
10048 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
10049 (__malloc_safe_bcopy): Remove; no longer needed.
10051 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
10052 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
10053 well either way, and we prefer signed to unsigned.
10055 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
10057 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
10058 closes the connection while we're reading (bug#9182).
10060 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10062 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
10063 are specified (Bug#9168).
10065 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
10067 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
10068 Found by GCC static checking and --with-wide-int on a 32-bit host.
10070 2011-07-25 Eli Zaretskii <eliz@gnu.org>
10072 * xdisp.c (compute_display_string_pos): Fix logic of caching
10073 previous display string position. Initialize cached_prev_pos to
10074 -1. Fixes slow-down at the beginning of a buffer.
10076 2011-07-24 Eli Zaretskii <eliz@gnu.org>
10078 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
10079 for attrs[LFACE_FONTSET_INDEX].
10081 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
10083 * xml.c (parse_region): Remove unused local
10084 that was recently introduced.
10086 2011-07-23 Eli Zaretskii <eliz@gnu.org>
10088 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
10089 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
10091 * xdisp.c (move_it_in_display_line_to): Record the best matching
10092 position for TO_CHARPOS while scanning the line, and restore it on
10093 exit if none of the characters scanned was an exact match.
10094 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
10095 when exact match is impossible due to invisible text, and the
10096 lines are truncated.
10098 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
10100 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
10103 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10105 Fix a significant slow-down of cursor motion with C-n, C-p,
10106 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
10107 auto-repeat under bidi redisplay in fontified buffers.
10108 * xdisp.c (compute_stop_pos_backwards): New function.
10109 (next_element_from_buffer): Call compute_stop_pos_backwards to
10110 find a suitable prev_stop when we find ourselves before
10112 (reseat): Don't look for prev_stop, as that could mean a very long
10114 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
10115 <cached_disp_overlay_modiff>: Cache for last found display string
10117 (compute_display_string_pos): Return the cached position if asked
10118 about the same buffer in the same area of character positions, and
10119 the buffer wasn't changed since the time the display string
10120 position was cached.
10122 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10124 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
10125 is an integer, which is important for empty lines. (Bug#9149)
10127 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
10129 * frame.c (Fmodify_frame_parameters): In tty case, update the
10130 default face if necessary (Bug#4238).
10132 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
10134 * editfns.c (Fstring_to_char): No need to explain what a character
10135 is in the docstring (Bug#6576).
10137 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10139 * xml.c (parse_region): Make sure we always return a tree.
10141 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
10143 * xml.c (parse_region): If a document contains only comments,
10146 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10148 * xml.c (make_dom): Return comments, too.
10150 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
10153 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
10154 and the surrounding thread.
10155 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
10156 rather than fgets, and retry after EINTR. Otherwise, 'emacs
10157 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
10159 * s/openbsd.h (BROKEN_SIGIO): Define.
10160 * unexelf.c (unexec) [__OpenBSD__]:
10161 Don't update the .mdebug section of the Alpha COFF symbol table.
10163 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10165 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
10168 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
10170 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
10171 This fixes some race conditions on the permissions of any newly
10174 * alloc.c (valid_pointer_p): Use pipe, not open.
10175 This fixes some permissions issues when debugging.
10177 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
10178 If fchown fails to set both uid and gid, try to set just gid,
10179 as that is sometimes allowed. Adjust the file's mode to eliminate
10180 setuid or setgid bits that are inappropriate if fchown fails.
10182 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
10184 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
10185 to compare Lisp_Objects.
10186 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
10187 global_gnutls_log_level, don't mistake it for a Lisp_Object.
10188 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
10190 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
10192 * lread.c (read_integer): Unread even EOF character.
10193 (read1): Likewise. Properly record start position of symbol.
10195 * lread.c (read1): Read `#:' as empty uninterned symbol if no
10196 symbol character follows.
10198 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
10200 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
10201 This works around a problem with the previous change to Fcopy_file.
10202 Recent glibc declares fchown with __attribute__((warn_unused_result)),
10203 and without this change, GCC might complain about discarding
10204 fchown's return value.
10206 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
10208 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
10210 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
10212 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
10214 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
10216 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
10217 it's used from the C level.
10219 * process.c: Use the same condition for POLL_FOR_INPUT in both
10220 keyboard.c and process.c (bug#1858).
10222 2011-07-09 Lawrence Mitchell <wence@gmx.li>
10224 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
10225 (Fgnutls_boot): Use it.
10227 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
10229 * doc.c (Fsubstitute_command_keys): Revert last change.
10231 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
10233 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
10234 quotes the next character, and doesn't affect other longer
10235 sequences (bug#8935).
10237 * lread.c (syms_of_lread): Clarify that is isn't only
10238 `eval-buffer' and `eval-defun' that's affected by
10239 `lexical-binding' (bug#8460).
10241 2011-07-15 Eli Zaretskii <eliz@gnu.org>
10243 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
10244 bidi redisplay when a line includes both an image and is truncated.
10246 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
10248 Fix minor problems found by static checking.
10249 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
10250 (elsz): Now a signed constant, not a size_t var. We prefer signed
10251 types to unsigned, to avoid integer comparison confusion. Without
10252 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
10253 "cannot optimize loop, the loop counter may overflow", a symptom
10255 * indent.c (Fvertical_motion): Mark locals as initialized.
10256 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
10258 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
10260 * search.c (Fre_search_backward): Mention `case-fold-search' in
10261 all the re_search_* functions (bug#8138).
10263 * keyboard.c (Fopen_dribble_file): Document when the file is

10274 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
10275 (reseat_to_string): Initialize bidi_it->string.s and
10276 bidi_it->string.schars.
10277 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
10278 NULL (avoids a crash in bidi_paragraph_init).
10279 Initialize itb.string.lstring.
10280 (init_iterator): Call bidi_init_it only of a valid
10281 buffer position was specified. Initialize paragraph_embedding to
10283 (reseat_to_string): Initialize the bidi iterator.
10284 (display_string): If we need to ignore text properties of
10285 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
10286 original value of -1 will not work with bidi.)
10287 (compute_display_string_pos): First arg is now struct
10288 `text_pos *'; all callers changed. Support display properties on
10290 (compute_display_string_end): Support display properties on Lisp
10292 (init_iterator, reseat_1, reseat_to_string): Initialize the
10293 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
10294 when iterating on a string not from display properties).
10295 (compute_display_string_pos, compute_display_string_end):
10296 Fix calculation of the object to scan. Fixes an error when using
10298 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
10299 base_level_stop; instead, set base_level_stop to BEGV.
10300 Fixes crashes in vertical-motion.
10301 (next_element_from_buffer): Improve commentary for when
10302 the iterator is before prev_stop.
10303 (init_iterator): Initialize bidi_p from the default value of
10304 bidi-display-reordering, not from buffer-local value. Use the
10305 buffer-local value only if initializing for buffer iteration.
10306 (handle_invisible_prop): Support invisible properties on strings
10307 that are being bidi-reordered.
10308 (set_iterator_to_next): Support bidi reordering of C strings and
10310 (next_element_from_string): Support bidi reordering of Lisp
10312 (handle_stop_backwards): Support Lisp strings as well.
10313 (display_string): Support display of R2L glyph rows.
10314 Use IT_STRING_CHARPOS when displaying from a Lisp string.
10315 (init_iterator): Don't initialize it->bidi_p for strings
10317 (reseat_to_string): Initialize it->bidi_p for strings here.
10318 (next_element_from_string, next_element_from_c_string)
10319 (next_element_from_buffer): Add xassert's for correspondence
10320 between IT's object being iterated and it->bidi_it.string
10322 (face_before_or_after_it_pos): Support bidi iteration.
10323 (next_element_from_c_string): Handle the case of the first string
10324 character that is not the first one in the visual order.
10325 (get_visually_first_element): New function, refactored from common
10326 parts of next_element_from_buffer, next_element_from_string, and
10327 next_element_from_c_string.
10328 (tool_bar_lines_needed, redisplay_tool_bar)
10329 (display_menu_bar): Force left-to-right direction. Add a FIXME
10330 comment for making that be controlled by a user option.
10331 (push_it, pop_it): Save and restore the state of the
10332 bidi iterator. Save and restore the bidi_p flag.
10333 (pop_it): Iterate out of display property for string iteration as
10335 (iterate_out_of_display_property): Support iteration over strings.
10336 (handle_single_display_spec): Set up it->bidi_it for iteration
10337 over a display string, and call bidi_init_it.
10338 (handle_single_display_spec, next_overlay_string)
10339 (get_overlay_strings_1, push_display_prop): Set up the bidi
10340 iterator for displaying display or overlay strings.
10341 (forward_to_next_line_start): Don't use the shortcut if
10343 (back_to_previous_visible_line_start): If handle_display_prop
10344 pushed the iterator stack, restore the internal state of the bidi
10345 iterator by calling bidi_pop_it same number of times.
10346 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
10347 and we are bidi-iterating, don't decrement the iterator position;
10348 instead, set the first_elt flag in the bidi iterator, to produce
10350 (reseat_1): Remove redundant setting of string_from_display_prop_p.
10351 (push_display_prop): xassert that we are iterating a buffer.
10352 (push_it, pop_it): Save and restore paragraph_embedding member.
10353 (handle_single_display_spec, next_overlay_string)
10354 (get_overlay_strings_1, reseat_1, reseat_to_string)
10355 (push_display_prop): Set up the `unibyte' member of bidi_it.string
10356 correctly. Don't assume unibyte strings are not bidi-reordered.
10357 (compute_display_string_pos)
10358 (compute_display_string_end): Fix handling the case of C string.
10359 (push_it, pop_it): Save and restore from_disp_prop_p.
10360 (handle_single_display_spec, push_display_prop): Set the
10361 from_disp_prop_p flag.
10362 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
10363 (pop_it): Call iterate_out_of_display_property only if we are
10364 popping after iteration over a string that came from a display
10365 property. Fix a typo in popping stretch info. Add an assertion
10366 for verifying that the iterator position is in sync with the bidi
10368 (handle_single_display_spec, get_overlay_strings_1)
10369 (push_display_prop): Fix initialization of paragraph direction for
10370 string when that of the parent object is not yet determined.
10371 (reseat_1): Call bidi_init_it to resync the bidi
10372 iterator with IT's position. (Bug#7616)
10373 (find_row_edges): If ROW->start.pos gives position
10374 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
10375 (handle_stop, back_to_previous_visible_line_start, reseat_1):
10376 Reset the from_disp_prop_p flag.
10377 (SAVE_IT, RESTORE_IT): New macros.
10378 (pos_visible_p, face_before_or_after_it_pos)
10379 (back_to_previous_visible_line_start)
10380 (move_it_in_display_line_to, move_it_in_display_line)
10381 (move_it_to, move_it_vertically_backward, move_it_by_lines)
10382 (try_scrolling, redisplay_window, display_line): Use them when
10383 saving a temporary copy of the iterator and restoring it back.
10384 (back_to_previous_visible_line_start, reseat_1)
10385 (init_iterator): Empty the bidi cache "stack".
10386 (move_it_in_display_line_to): If iterator ended up at
10387 EOL, but we never saw any buffer positions smaller than
10388 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
10389 motion in bidi-reordered lines.
10390 (move_it_in_display_line_to): Record prev_method and prev_pos
10391 immediately before the call to set_iterator_to_next. Fixes cursor
10392 motion in bidi-reordered lines with stretch glyphs and strings
10393 displayed in margins. (Bug#8133) (Bug#8867)
10394 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
10396 (pos_visible_p): Support positions in bidi-reordered lines.
10397 Save and restore bidi cache.
10399 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
10400 (bidi_paragraph_info): Delete unused struct.
10401 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
10402 (bidi_cache_start): New variable.
10403 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
10405 (bidi_cache_fetch_state, bidi_cache_search)
10406 (bidi_cache_find_level_change, bidi_cache_iterator_state)
10407 (bidi_cache_find, bidi_peek_at_next_level)

10411 (bidi_fetch_char): Accept new argument STRING; all callers
10412 changed. Support iteration over a string. Support strings with
10413 display properties. Support unibyte strings. Fix the type of
10414 `len' according to what STRING_CHAR_AND_LENGTH expects.
10415 (bidi_paragraph_init, bidi_resolve_explicit_1)
10416 (bidi_resolve_explicit, bidi_resolve_weak)
10417 (bidi_level_of_next_char, bidi_move_to_visually_next):
10418 Support iteration over a string.
10419 (bidi_set_sor_type, bidi_resolve_explicit_1)
10420 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
10421 can now be zero (for strings); special values 0 and -1 were

10512 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
10513 The old code sometimes used this field without initializing it.
10515 * alloc.c (gc_sweep): Don't read past end of array.
10516 In theory, the old code could also have corrupted Emacs internals,
10517 though it'd be very unlikely.

10782 This isn't true in general, and it's particularly not true
10783 if Emacs is configured with --with-wide-int.
10784 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
10785 New macros, used in the buffer.c change.

10821 Random fixes. E.g., (random) never returned negative values.
10822 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10823 subseconds part to the entropy, as that's a bit more random.
10824 Prefer signed to unsigned, since the signedness doesn't matter and
10825 in general we prefer signed. When given a limit, use a
10826 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10827 latter isn't right if USE_2_TAGS_FOR_INTS.
10828 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10829 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10841 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10842 This is more efficient than Ffile_directory_p and avoids a minor race.
10844 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
10846 * buffer.c (Foverlay_put): Say what the return value is
10849 * fileio.c (barf_or_query_if_file_exists): Check first if the file
10850 is a directory before asking whether to use the file name
10852 (barf_or_query_if_file_exists): Make the "File is a directory"
10853 error be more correct.
10855 * fns.c (Frequire): Remove the mention of the .gz files, since
10856 that's installation-specific, but keep the mention of
10857 `get-load-suffixes'.

10861 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

10974 * eval.c (struct backtrace): Simplify and port the data structure.
10975 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10976 signed bit field, as this assumption is not portable and it makes
10977 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10978 "char debug_on_exit : 1" as this is not portable either; instead,
10979 use the portable "unsigned int debug_on_exit : 1". Remove unused
10980 member evalargs. Remove obsolete comments about cc bombing out.

11215 on undefined behavior with wrong number of arguments.
11216 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
11217 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
11218 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
11219 since we're not interested in debugging glyphs with old libraries.
11220 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
11221 GCC 4.6.0's static checking.

11263 (x_session_initialize): Do not assume string length fits in int.
11265 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
11266 This is unlikely, but can occur if DPI is outlandish.
11268 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):

11291 * minibuf.c (Fread_buffer):
11292 * lread.c (intern, intern_c_string):
11293 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

11307 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
11308 Reformulate so as not to need the command string.
11309 Invoke gzip -cd rather than gunzip, as it's more portable.
11310 (lock_info_type, lock_file_1, lock_file):
11311 Don't assume pid_t and time_t fit in unsigned long.
11312 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
11313 (current_lock_owner): Prefer signed type for sizes.
11314 Use memcpy, not strncpy, where memcpy is what is really wanted.
11315 Don't assume (via atoi) that time_t and pid_t fit in int.
11316 Check for time_t and/or pid_t out of range, e.g., via a network share.
11317 Don't alloca where an auto var works fine.
11319 * fileio.c: Fix some integer overflow issues.
11320 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
11321 Don't assume string length fits in int.
11322 (directory_file_name): Don't assume string length fits in long.
11323 (make_temp_name): Don't assume pid fits in int, or that its print
11324 length is less than 20.
11326 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
11328 * coding.c (make_subsidiaries): Don't assume string length fits in int.
11330 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
11332 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
11333 We prefer signed integers, even for size calculations.
11335 * emacs.c: Don't assume string length fits in 'int'.
11336 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
11337 (main): Don't invoke strlen when not needed.
11339 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
11340 (XD_DEBUG_MESSAGE): Don't waste a byte.
11342 * callproc.c (getenv_internal_1, getenv_internal)
11343 (Fgetenv_internal):
11344 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
11346 * lread.c (invalid_syntax): Omit length argument.
11347 All uses changed. This doesn't fix a bug, but it simplifies the
11348 code away from its former Hollerith-constant appearance, and it's
11349 one less 'int' to worry about when looking at integer-overflow issues.
11350 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
11352 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
11353 This didn't break anything, but it didn't help either.
11354 It's confusing to put a bogus integer in a place where the actual
11355 value does not matter.
11356 (LIST_END_P): Remove unused macro and its bogus comment.
11357 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
11359 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
11360 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
11362 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
11363 We prefer signed types, and the value cannot exceed the EMACS_INT
11364 range anyway (because otherwise the length would not be representable).
11365 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
11366 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
11367 This avoids a GCC warning when WIDE_EMACS_INT.
11369 * indent.c (sane_tab_width): New function.
11370 (current_column, scan_for_column, Findent_to, position_indentation)
11371 (compute_motion): Use it. This is just for clarity.
11372 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
11374 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
11376 * lisp.h (lint_assume): New macro.
11377 * composite.c (composition_gstring_put_cache):
11378 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
11380 * editfns.c, insdel.c:
11381 Omit unnecessary forward decls, to simplify future changes.
11383 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
11385 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
11387 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
11388 Use much-faster test for byte-length change.
11389 Don't assume string byte-length fits in 'int'.
11390 Check that character arg fits in 'int'.
11391 (mapcar1): Declare byte as byte, for clarity.
11393 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
11395 * fns.c (concat): Catch string overflow earlier.
11396 Do not rely on integer wraparound.
11398 * dispextern.h (struct it.overlay_strings_charpos)
11399 (struct it.selective): Now EMACS_INT, not int.
11400 * xdisp.c (forward_to_next_line_start)
11401 (back_to_previous_visible_line_start)
11402 (reseat_at_next_visible_line_start, next_element_from_buffer):
11403 Don't arbitrarily truncate the value of 'selective' to int.
11405 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
11407 * composite.c: Don't truncate sizes to 'int'.
11408 (composition_gstring_p, composition_reseat_it)
11409 (composition_adjust_point): Use EMACS_INT, not int.
11410 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
11411 not EMACS_UINT, for indexes.
11413 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
11415 * buffer.c: Include <verify.h>.
11416 (struct sortvec.priority, struct sortstr.priority):
11417 Now EMACS_INT, not int.
11418 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
11419 (struct sortstr.size, record_overlay_string)
11420 (struct sortstrlist.size, struct sortlist.used):
11421 Don't truncate size to int.
11422 (record_overlay_string): Check for size-calculation overflow.
11423 (init_buffer_once): Check at compile-time, not run-time.
11425 2011-06-22 Jim Meyering <meyering@redhat.com>
11427 Don't leak an XBM-image-sized buffer
11428 * image.c (xbm_load): Free the image buffer after using it.
11430 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
11433 * composite.c (find_automatic_composition): Omit needless 'return 0;'
11434 that Sun C diagnosed.
11435 * fns.c (secure_hash): Fix pointer signedness issue.
11436 * intervals.c (static_offset_intervals): New function.
11437 (offset_intervals): Use it.
11439 2011-06-21 Leo Liu <sdl.web@gmail.com>
11442 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
11445 * fns.c (secure_hash): Rename from crypto_hash_function and change
11446 the first arg to accept symbols.
11447 (Fsecure_hash): New primitive.
11448 (syms_of_fns): New symbols.
11450 2011-06-20 Deniz Dogan <deniz@dogan.se>
11452 * process.c (Fset_process_buffer): Clarify return value in
11455 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
11457 * dispnew.c (add_window_display_history): Use BVAR.
11459 * xdisp.c (debug_method_add): Use BVAR.
11460 (check_window_end, dump_glyph_matrix, dump_glyph)
11461 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
11463 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
11466 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
11467 check till after the cache is created in init_frame_faces.
11469 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
11471 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
11473 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
11475 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
11476 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
11477 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
11479 Improve buffer-overflow checking (Bug#8873).
11480 * fileio.c (Finsert_file_contents):
11481 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
11482 Remove the old (too-loose) buffer overflow checks.
11483 They weren't needed, since make_gap checks for buffer overflow.
11484 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
11485 The old code merely checked for Emacs fixnum overflow, and relied
11486 on undefined (wraparound) behavior. The new code avoids undefined
11487 behavior, and also checks for ptrdiff_t and/or size_t overflow.
11489 * editfns.c (Finsert_char): Don't dump core with very negative counts.
11490 Tune. Don't use wider integers than needed. Don't use alloca.
11491 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11493 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11495 * insdel.c, lisp.h (buffer_overflow): New function.
11496 (insert_from_buffer_1, replace_range, replace_range_2):
11497 * insdel.c (make_gap_larger):
11498 * editfns.c (Finsert_char):
11499 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11501 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11503 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11505 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11507 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11508 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11510 * fileio.c: Don't assume EMACS_INT fits in off_t.
11511 (emacs_lseek): New static function.
11512 (Finsert_file_contents, Fwrite_region): Use it.
11513 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11515 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11517 * fns.c: Don't overflow int when computing a list length.
11518 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11519 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11520 truncation on 64-bit hosts. Check for QUIT every
11521 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11522 faster and is responsive enough.
11523 (Flength): Report an error instead of overflowing an integer.
11524 (Fsafe_length): Return a float if the value is not representable
11525 as a fixnum. This shouldn't happen except in contrived situations.
11526 (Fnthcdr, Fsort): Don't assume list length fits in int.
11527 (Fcopy_sequence): Don't assume vector length fits in int.
11529 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11530 (header_size, word_size): New constants.
11531 (allocate_vectorlike): Don't check size overflow here.
11532 (allocate_vector): Check it here instead, since this is the only
11533 caller of allocate_vectorlike that could cause overflow.
11534 Check that the new vector's length is representable as a fixnum.
11536 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11537 The previous code was bogus. For example, next_almost_prime (32)
11538 returned 39, which is undesirable as it is a multiple of 3; and
11539 next_almost_prime (24) returned 25, which is a multiple of 5 so
11540 why was the code bothering to check for multiples of 7?
11542 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11544 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11546 Variadic C functions now count arguments with ptrdiff_t.
11547 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11548 Back then I didn't know that the Emacs coding style prefers signed int.
11549 Also, in the meantime I found a few more instances where arguments
11550 were being counted with int, which may truncate counts on 64-bit
11551 machines, or EMACS_INT, which may be unnecessarily wide.
11552 * lisp.h (struct Lisp_Subr.function.aMANY)
11553 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11554 Arg counts are now ptrdiff_t, not size_t.
11555 All variadic functions and their callers changed accordingly.
11556 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11557 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11558 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11559 * callint.c (Fcall_interactively): Check arg count for overflow,
11560 to avoid potential buffer overrun. Use signed char, not 'int',
11561 for 'varies' array, so that we needn't bother to check its size
11562 calculation for overflow.
11563 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11564 * eval.c (apply_lambda):
11565 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11566 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11567 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11569 * callint.c (Fcall_interactively): Don't use index var as event count.
11571 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11572 * mem-limits.h (SIZE): Remove; no longer used.
11574 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11576 Remove unnecessary casts.
11577 * xterm.c (x_term_init):
11578 * xfns.c (x_set_border_pixel):
11579 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11580 These aren't needed now that we assume ANSI C.
11582 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11583 It's more likely to cause problems (due to unsigned overflow)
11586 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11588 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11590 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11592 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11594 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11596 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11598 GLYPH_CODE_FACE returns EMACS_INT, not int.
11599 * dispextern.h (merge_faces):
11600 * xfaces.c (merge_faces):
11601 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11602 Don't assume EMACS_INT fits in int.
11604 * character.h (CHAR_VALID_P): Remove unused parameter.
11605 * fontset.c, lisp.h, xdisp.c: All uses changed.
11607 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11609 * fns.c (concat): Minor tuning based on overflow analysis.
11610 This doesn't fix any bugs. Use int to hold character, instead
11611 of constantly refetching from Emacs object. Use XFASTINT, not
11612 XINT, for value known to be a character. Don't bother comparing
11613 a single byte to 0400, as it's always less.
11615 * floatfns.c (Fexpt):
11616 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11618 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11621 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11623 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11624 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11625 incorrectly succeed when S was a string, because 4294967386 was
11626 truncated before it was used.
11628 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11629 Otherwise, an out-of-range integer could cause undefined behavior
11632 * composite.c: Use int, not EMACS_INT, for characters.
11633 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11634 EMACS_INT, for values that are known to be in character range.
11635 This doesn't fix any bugs but is the usual style inside Emacs and
11636 may generate better code on 32-bit machines.
11638 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11639 This is for reasons similar to the recent CHAR_STRING fix.
11640 * charset.c (Fencode_char): Check that character arg is actually
11641 a character. Pass an int to ENCODE_CHAR.
11642 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11643 wider than 'int', as a compile-time check to prevent future regressions
11646 * character.c (char_string): Remove unnecessary casts.
11648 Make sure a 64-bit char is never passed to CHAR_STRING.
11649 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11650 by silently ignoring the top 32 bits, allowing some values
11651 that were far too large to be valid characters.
11652 * character.h: Include <verify.h>.
11653 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11654 arguments are no wider than unsigned, as a compile-time check
11655 to prevent future regressions in this area.
11657 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11658 (Fsubst_char_in_region):
11660 * xdisp.c (decode_mode_spec_coding):
11661 Adjust to CHAR_STRING's new requirement.
11662 * editfns.c (Finsert_char, Fsubst_char_in_region):
11663 * fns.c (concat): Check that character args are actually
11664 characters. Without this test, these functions did the wrong
11665 thing with wildly out-of-range values on 64-bit hosts.
11667 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11668 These casts should not be needed on 32-bit hosts, either.
11669 * keyboard.c (read_char):
11670 * lread.c (Fload): Remove casts to unsigned.
11672 * lisp.h (UNSIGNED_CMP): New macro.
11673 This fixes comparison bugs on 64-bit hosts.
11674 (ASCII_CHAR_P): Use it.
11675 * casefiddle.c (casify_object):
11676 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11677 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11678 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11679 * dispextern.h (FACE_FROM_ID):
11680 * keyboard.c (read_char): Use UNSIGNED_CMP.
11682 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11683 not to EMACS_INT, to avoid GCC warning.
11685 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11687 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11688 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11689 isn't needed on 32-bit machines.
11691 * buffer.c (Fgenerate_new_buffer_name):
11692 Use EMACS_INT for count, not int.
11693 (advance_to_char_boundary): Return EMACS_INT, not int.
11695 * data.c (Qcompiled_function): Now static.
11697 * window.c (window_body_lines): Now static.
11699 * image.c (gif_load): Rename local to avoid shadowing.
11701 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11702 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11703 * alloc.c (make_save_value): Integer argument is now of type
11704 ptrdiff_t, not int.
11705 (mark_object): Use ptrdiff_t, not int.
11706 * lisp.h (pD): New macro.
11707 * print.c (print_object): Use it.
11709 * alloc.c: Use EMACS_INT, not int, to count objects.
11710 (total_conses, total_markers, total_symbols, total_vector_size)
11711 (total_free_conses, total_free_markers, total_free_symbols)
11712 (total_free_floats, total_floats, total_free_intervals)
11713 (total_intervals, total_strings, total_free_strings):
11714 Now EMACS_INT, not int. All uses changed.
11715 (Fgarbage_collect): Compute overall total using a double, so that
11716 integer overflow is less likely to be a problem. Check for overflow
11717 when converting back to an integer.
11718 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11719 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11720 These were 'int' variables that could overflow on 64-bit hosts;
11721 they were never used, so remove them instead of repairing them.
11722 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11723 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11724 Previously, this ceilinged at INT_MAX, but that doesn't work on
11726 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11728 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11729 (allocate_vectorlike): Check for ptrdiff_t overflow.
11730 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11731 when a (possibly-narrower) signed value would do just as well.
11732 We prefer using signed arithmetic, to avoid comparison confusion.
11734 * alloc.c: Catch some string size overflows that we were missing.
11735 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11736 for convenience in STRING_BYTES_MAX.
11737 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11738 The definition here is exact; the one in lisp.h was approximate.
11739 (allocate_string_data): Check for string overflow. This catches
11740 some instances we weren't catching before. Also, it catches
11741 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11742 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11743 and ptrdiff_t and EMACS_INT are both 64 bits.

12187 * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
12189 Minor fixes for signed vs unsigned integers.
12190 * character.h (MAYBE_UNIFY_CHAR):
12191 * charset.c (maybe_unify_char):
12192 * keyboard.c (read_char, reorder_modifiers):
12193 XINT -> XFASTINT, since the integer must be nonnegative.
12194 * ftfont.c (ftfont_spec_pattern):
12195 * keymap.c (access_keymap, silly_event_symbol_error):
12196 XUINT -> XFASTINT, since the integer must be nonnegative.
12197 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
12198 since it makes no difference and we prefer signed.
12199 * keyboard.c (record_char): Use XUINT when all the neighbors do.
12200 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

12247 code. Minor doc-string fixes.
12249 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
12251 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
12252 Do not assume that spare memory exists; that assumption is valid
12253 only if SYSTEM_MALLOC.
12254 (LARGE_REQUEST): New macro, so that the issue of large requests
12255 is separated from the issue of spare memory.
12257 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
12259 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

12285 New error handlers.
12286 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
12287 Obey Vx_select_enable_clipboard_manager. Catch errors in
12288 x_clipboard_manager_save (Bug#8779).
12289 (Vx_select_enable_clipboard_manager): New variable.
12290 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
12292 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
12294 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
12296 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12298 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
12299 in the current matrix if keep_current_p is non-zero.

12311 (bidi_cache_search, bidi_cache_iterator_state)
12312 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12313 (bidi_level_of_next_char, bidi_move_to_visually_next):
12314 Support character positions inside a run of characters covered by a
12316 (bidi_paragraph_init, bidi_resolve_explicit_1)
12317 (bidi_level_of_next_char): Call bidi_fetch_char and
12318 bidi_fetch_char_advance instead of FETCH_CHAR and

12321 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
12323 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
12324 instead of using explicit *_CHAR codes.
12325 (bidi_resolve_explicit, bidi_resolve_weak):
12326 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
12327 bidirectional text is supported only in multibyte buffers.
12328 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
12329 it to initialize the frame_window_p member of struct bidi_it.
12330 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
12331 (bidi_resolve_explicit, bidi_resolve_weak)

12333 bidi_it->nchars is non-positive.
12334 (bidi_level_of_next_char): Don't try to lookup the cache for the
12335 next/previous character if nothing is cached there yet, or if we
12336 were just reseat()'ed to a new position.
12338 * xdisp.c (set_cursor_from_row): Set start and stop points
12339 according to the row's direction when priming the loop that looks
12340 for the glyph on which to display cursor.
12341 (single_display_spec_intangible_p): Function deleted.
12342 (display_prop_intangible_p): Reimplement to call
12343 handle_display_spec instead of single_display_spec_intangible_p.
12344 Accept 3 additional arguments needed by handle_display_spec.
12345 This fixes incorrect cursor motion across display property with complex
12346 values: lists, `(when COND...)' forms, etc.
12347 (single_display_spec_string_p): Support property values that are
12348 lists with the argument STRING its top-level element.
12349 (display_prop_string_p): Fix the condition for processing a
12350 property that is a list to be consistent with handle_display_spec.

12352 last portion of handle_display_prop.
12353 (compute_display_string_pos): Accept additional argument
12354 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
12355 value of a `display' property is a "replacing spec".
12356 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
12357 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
12358 the display property, but just return a value indicating whether
12359 the display property will replace the characters it covers.
12360 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
12361 frame_window_p members of struct bidi_it.
12362 (compute_display_string_pos, compute_display_string_end):
12364 (push_it): Accept second argument POSITION, where pop_it should
12365 jump to continue iteration.
12366 (reseat_1): Initialize bidi_it.disp_pos.
12368 * keyboard.c (adjust_point_for_property): Adjust the call to
12369 display_prop_intangible_p to its new signature.
12371 * dispextern.h (struct bidi_it): New member frame_window_p.
12372 (bidi_init_it): Update prototypes.
12373 (display_prop_intangible_p): Update prototype.
12374 (compute_display_string_pos, compute_display_string_end):
12375 Declare prototypes.
12376 (struct bidi_it): New members nchars and disp_pos. ch_len is now
12379 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
12381 Malloc failure behavior now depends on size of allocation.
12382 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
12383 * lisp.h: Change signatures accordingly.
12384 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
12385 All callers changed. (Bug#8762)
12387 * gnutls.c: Use Emacs's memory allocators.
12388 Without this change, the gnutls library would invoke malloc etc.
12389 directly, which causes problems on non-SYNC_INPUT hosts, and which
12390 runs afoul of improving memory_full behavior. (Bug#8761)
12391 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
12392 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
12393 xfree instead of the default malloc, realloc, free.
12394 (Fgnutls_boot): No need to check for memory allocation failure,
12395 since xmalloc does that for us.
12397 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
12398 * category.c (hash_get_category_set):
12399 * ccl.c (ccl_driver):

12411 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
12412 (Fsxhash, Fgethash, Fputhash, Fmaphash):
12413 * image.c (make_image, search_image_cache, lookup_image)
12414 (xpm_put_color_table_h):
12415 * lisp.h (struct Lisp_Hash_Table):
12416 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
12417 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
12418 for hashes and hash indexes, instead of 'unsigned' and 'int'.
12419 * alloc.c (allocate_vectorlike):
12420 Check for overflow in vector size calculations.
12421 * ccl.c (ccl_driver):
12422 Check for overflow when converting EMACS_INT to int.
12423 * fns.c, image.c: Remove unnecessary static decls that would otherwise
12424 need to be updated by these changes.
12425 * fns.c (make_hash_table, maybe_resize_hash_table):
12426 Check for integer overflow with large hash tables.
12427 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
12428 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
12429 (SXHASH_REDUCE): New macro.
12430 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
12431 Use it instead of discarding useful hash info with large hash values.
12432 (sxhash_float): New function.
12433 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
12434 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
12435 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
12436 Rewrite to use FIXNUM_BITS, as this simplifies things.
12437 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
12438 Adjust signatures to match updated version of code.
12439 (consing_since_gc): Now EMACS_INT, since a single hash table can
12440 use more than INT_MAX bytes.
12442 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
12444 Make it possible to build with GCC-4.6+ -O2 -flto.
12446 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
12448 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
12450 * minibuf.c (get_minibuffer, read_minibuf_unwind):
12451 Call minibuffer-inactive-mode.
12453 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
12455 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
12456 Update dependencies.
12458 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12460 * data.c (init_data): Remove code for UTS, this system is not
12463 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12465 Don't force ./temacs to start in terminal mode.
12467 * frame.c (make_initial_frame): Initialize faces in all cases, not
12468 only when CANNOT_DUMP is defined.
12469 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
12471 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12473 * dispnew.c (add_window_display_history): Use const for the string
12474 pointer. Remove declaration, not needed.
12476 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12478 Use 'inline', not 'INLINE'.
12479 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
12480 * alloc.c, fontset.c (INLINE): Remove.
12481 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
12482 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
12483 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
12484 * gmalloc.c (register_heapinfo): Use inline unconditionally.
12485 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
12487 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12489 Make it possible to run ./temacs.
12491 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12492 syms_of_callproc does the same thing. Remove test for
12493 "initialized", do it in the caller.
12494 * emacs.c (main): Avoid calling set_initial_environment when dumping.
12496 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
12498 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
12499 (read_minibuf): Use get_minibuffer.
12500 (syms_of_minibuf): Use DEFSYM.
12501 (Qmetadata): New var.
12502 * data.c (Qbuffer): Don't make it static.
12503 (syms_of_data): Use DEFSYM.
12505 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12507 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12508 (CCL_CODE_MIN): New macro.
12510 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12512 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12514 * eval.c (Qdebug): Now static.
12515 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12516 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12517 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12519 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12521 * image.c: Various fixes to ImageMagick code comments.
12522 (Fimagemagick_types): Doc fix.
12524 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12526 Minor fixes prompted by GCC 4.6.0 warnings.
12528 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12530 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12531 (x_clipboard_manager_save_all): Move extern decl to ...
12532 * xterm.h: ... here, so that it can be checked for consistency.
12534 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12536 * xselect.c (x_clipboard_manager_save_frame)
12537 (x_clipboard_manager_save_all): New functions.
12538 (Fx_clipboard_manager_save): Lisp function deleted.
12540 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12541 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12543 * xterm.h: Update prototype.
12545 2011-05-28 William Xu <william.xwl@gmail.com>
12547 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12548 exiting (Bug#8239).
12550 2011-05-28 Jim Meyering <meyering@redhat.com>
12552 Avoid a sign-extension bug in crypto_hash_function.
12553 * fns.c (to_uchar): Define.
12554 (crypto_hash_function): Use it to convert some newly-signed
12555 variables to unsigned, to avoid sign-extension bugs. For example,
12556 without this change, (md5 "truc") would evaluate to
12557 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12558 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12559 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12561 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12563 Integer overflow fixes.
12565 * dbusbind.c: Serial number integer overflow fixes.
12566 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12567 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12568 to hold a serial number that is too large for a fixnum.
12569 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12570 Check for serial numbers out of range. Decode any serial number
12571 that was so large that it became a float. (Bug#8722)
12573 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12574 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12575 Use XFASTINT rather than XUINT when numbers are nonnegative.
12576 (xd_append_arg, Fdbus_method_return_internal):
12577 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12578 arguments, check that Lisp number is nonnegative, rather than
12579 silently wrapping negative numbers around. (Bug#8722)
12580 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12583 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12585 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12587 ccl: Add integer overflow checks.
12588 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12589 (IN_INT_RANGE): New macros.
12590 (ccl_driver): Use them to check for integer overflow when
12591 decoding a CCL program. Many of the new checks are whether XINT (x)
12592 fits in int; it doesn't always, on 64-bit hosts. The new version
12593 doesn't catch all possible integer overflows, but it's an
12594 improvement. (Bug#8719)
12596 * alloc.c (make_event_array): Use XINT, not XUINT.
12597 There's no need for unsigned here.
12599 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12600 This follows up to the 2011-05-06 change that substituted uintptr_t
12601 for EMACS_INT. This case wasn't caught back then.
12603 Rework Fformat to avoid integer overflow issues.
12604 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12605 now (part of C89). Include <verify.h>.
12606 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12607 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12608 (Fformat): Avoid the prepass trying to compute sizes; it was only
12609 approximate and thus did not catch overflow reliably. Instead, walk
12610 through the format just once, formatting and computing sizes as we go,
12611 checking for integer overflow at every step, and allocating a larger
12612 buffer as needed. Keep track separately whether the format is
12613 multibyte. Keep only the most-recently calculated precision, rather
12614 than them all. Record whether each argument has been converted to
12615 string. Use EMACS_INT, not int, for byte and char and arg counts.
12616 Support field widths and precisions larger than INT_MAX. Avoid
12617 sprintf's undefined behavior with conversion specifications such as %#d
12618 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12619 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12620 formatting out-of-range floating point numbers with int
12621 formats. (Bug#8668)
12623 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12625 * data.c: Avoid integer truncation in expressions involving floats.
12626 * data.c: Include <intprops.h>.
12627 (arith_driver): When there's an integer overflow in an expression
12628 involving floating point, convert the integers to floating point
12629 so that the resulting value does not suffer from catastrophic
12630 integer truncation. For example, on a 64-bit host (* 4
12631 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12632 Do not rely on undefined behavior after integer overflow.
12634 merge count_size_as_multibyte, parse_str_to_multibyte
12635 * character.c, character.h (count_size_as_multibyte):
12636 Rename from parse_str_to_multibyte; all uses changed.
12637 Check for integer overflow.
12638 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12639 since it's now a duplicate of the other. This is more of
12640 a character than a buffer op, so better that it's in character.c.
12641 * fns.c, print.c: Adjust to above changes.
12643 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12645 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12647 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12649 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12650 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12651 (x_clipboard_manager_save): Now static.
12652 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12654 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12655 (crypto_hash_function): Now static.
12656 Fix pointer signedness problems. Avoid unnecessary initializations.
12658 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12660 * termhooks.h (Vselection_alist): Make it terminal-local.
12662 * terminal.c (create_terminal): Initialize it.
12664 * xselect.c: Support for clipboard managers.
12665 (Vselection_alist): Move to termhooks.h as terminal-local var.
12666 (LOCAL_SELECTION): New macro.
12667 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12668 (symbol_to_x_atom): Remove gratuitous arg.
12669 (x_handle_selection_request, lisp_data_to_selection_data)
12670 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12671 (x_own_selection, x_get_local_selection, x_convert_selection):
12672 New arg, specifying work frame. Use terminal-local Vselection_alist.
12673 (some_frame_on_display): Delete unused function.
12674 (Fx_own_selection_internal, Fx_get_selection_internal)
12675 (Fx_disown_selection_internal, Fx_selection_owner_p)
12676 (Fx_selection_exists_p): New optional frame arg.
12677 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12678 (x_handle_selection_clear): Don't treat other terminals with the
12679 same keyboard specially. Use the terminal-local Vselection_alist.
12680 (x_clear_frame_selections): Use Frun_hook_with_args.
12682 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12684 * xterm.h: Add support for those atoms.
12686 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12688 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12689 (converted_selections, conversion_fail_tag): New global variables.
12690 (x_selection_request_lisp_error): Free the above.
12691 (x_get_local_selection): Remove unnecessary code.
12692 (x_reply_selection_request): Args changed; handle arbitrary array
12693 of converted selections stored in converted_selections.
12694 Separate the XChangeProperty and SelectionNotify steps.
12695 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12696 (x_convert_selection): New function.
12697 (x_handle_selection_event): Simplify.
12698 (x_get_foreign_selection): Don't ignore incoming requests while
12699 waiting for an answer; this will fail when we implement
12700 SAVE_TARGETS, and seems unnecessary anyway.
12701 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12702 (Vx_sent_selection_functions): Doc fix.
12704 2011-05-26 Leo Liu <sdl.web@gmail.com>
12706 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12708 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12710 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12712 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12713 for fringe update if it has periodic bitmap.
12714 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12715 and fringe_bitmap_periodic_p.
12717 * fringe.c (get_fringe_bitmap_data): New function.
12718 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12719 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12720 row. Mark glyph row for fringe update if periodicity changed.
12722 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12723 for fringe update unless it has periodic bitmap.
12725 2011-05-25 Kenichi Handa <handa@m17n.org>
12727 * xdisp.c (get_next_display_element): Set correct it->face_id for
12728 a static composition.
12730 2011-05-24 Leo Liu <sdl.web@gmail.com>
12733 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12735 * fns.c (crypto_hash_function, Fsha1): New function.
12736 (Fmd5): Use crypto_hash_function.
12737 (syms_of_fns): Add Ssha1.
12739 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12741 * gnutls.c: Remove unused macros.
12742 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12743 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12744 Remove macros that are defined and never used.
12745 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12747 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12749 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12750 (Fx_get_selection_internal): Minor cleanup.
12751 (Fx_own_selection_internal): Rename arguments for consistency with
12754 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12756 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12758 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12760 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12762 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12764 * dispnew.c (scrolling_window): Don't exclude the case that the
12765 last enabled row in the desired matrix touches the bottom boundary.
12767 2011-05-21 Glenn Morris <rgm@gnu.org>
12769 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12770 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12771 and add some more files.
12773 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12775 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12776 report_file_error introduced by the change from 2011-05-07.
12778 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12780 * systime.h (Time): Define only if emacs is defined.
12781 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12782 where the include path doesn't have X11/X.h by default. See
12783 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12785 2011-05-20 Kenichi Handa <handa@m17n.org>
12787 * composite.c (find_automatic_composition): Fix previous change.
12789 2011-05-20 Glenn Morris <rgm@gnu.org>
12791 * lisp.mk: New file, split from Makefile.in.
12792 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12793 (shortlisp): Remove.
12794 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12796 2011-05-19 Glenn Morris <rgm@gnu.org>
12798 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12799 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12800 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12801 (lisp): Set the order to that of loadup.el.
12802 (shortlisp): Make it a copy of $lisp.
12803 (SOME_MACHINE_LISP): Remove.
12804 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12805 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12807 2011-05-18 Kenichi Handa <handa@m17n.org>
12809 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12810 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12811 (find_automatic_composition): Mostly rewrite for efficiency.
12813 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12815 * makefile.w32-in: Update dependencies.
12817 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12819 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12820 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12822 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12824 Fix some integer overflow issues, such as string length overflow.
12826 * insdel.c (count_size_as_multibyte): Check for string overflow.
12828 * character.c (lisp_string_width): Check for string overflow.
12829 Use EMACS_INT, not int, for string indexes and lengths; in
12830 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12831 the resulting string length overflows an EMACS_INT; instead,
12832 report a string overflow if no precision given. When checking for
12833 precision exhaustion, use a check that cannot possibly have
12834 integer overflow. (Bug#8675)
12835 * character.h (lisp_string_width): Adjust to new signature.
12837 * alloc.c (string_overflow): New function.
12838 (Fmake_string): Use it. This doesn't change behavior, but saves
12839 a few bytes and will simplify future changes.
12840 * character.c (string_escape_byte8): Likewise.
12841 * lisp.h (string_overflow): New decl.
12843 Fixups, following up to the user-interface timestamp change.
12844 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12845 for UI timestamps, instead of unsigned long.
12846 * msdos.c (mouse_get_pos): Likewise.
12847 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12848 * w32gui.h (Time): Define by including "systime.h" rather than by
12849 declaring it ourselves. (Bug#8664)
12851 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12852 * image.c (clear_image_cache): Likewise.
12854 * term.c (term_mouse_position): Don't assume time_t wraparound.
12856 Be more systematic about user-interface timestamps.
12857 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12858 and sometimes 'EMACS_UINT', to represent these timestamps.
12859 This change causes it to use 'Time' uniformly, as that's what X uses.
12860 This makes the code easier to follow, and makes it easier to catch
12861 integer overflow bugs such as Bug#8664.
12862 * frame.c (Fmouse_position, Fmouse_pixel_position):
12863 Use Time, not unsigned long, for user-interface timestamps.
12864 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12865 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12866 * keyboard.h (last_event_timestamp): Likewise.
12867 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12868 * menu.h (xmenu_show): Likewise.
12869 * term.c (term_mouse_position): Likewise.
12870 * termhooks.h (struct input_event.timestamp): Likewise.
12871 (struct terminal.mouse_position_hook): Likewise.
12872 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12873 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12874 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12875 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12876 what it was before.
12877 * menu.h, termhooks.h: Include "systime.h", for Time.
12879 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12880 Don't assume that the difference between two unsigned long values
12881 can fit into an integer. At this point, we know button_down_time
12882 <= event->timestamp, so the difference must be nonnegative, so
12883 there's no need to cast the result if double-click-time is
12884 nonnegative, as it should be; check that it's nonnegative, just in
12885 case. This bug is triggered when events are more than 2**31 ms
12886 apart (about 25 days). (Bug#8664)
12888 * xselect.c (last_event_timestamp): Remove duplicate decl.
12889 (x_own_selection): Remove needless cast to unsigned long.
12891 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12892 that always fit in int. Use a sentinel instead of a counter, to
12893 avoid a temp and to allay GCC's concerns about possible int overflow.
12894 * frame.h (struct frame): Use int for menu_bar_items_used
12895 instead of EMACS_INT, since it always fits in int.
12897 * menu.c (grow_menu_items): Check for int overflow.
12899 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12901 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12902 Before, the code was not consistent. These values cannot exceed
12903 2**31 - 1 so there's no need to make them unsigned.
12904 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12905 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12906 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12908 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12910 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12911 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12912 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12913 presumably because the widths might not match.
12915 * window.c (size_window): Avoid needless test at loop start.
12917 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12919 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12921 2011-05-12 Drew Adams <drew.adams@oracle.com>
12923 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12925 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12927 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12928 `width' to `bar_area_x' and `bar_area_width', respectively.
12929 (x_scroll_run): Take account of fringe background extension.
12931 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12932 Rename local vars `left' and `width' to `bar_area_x' and
12933 `bar_area_width', respectively.
12934 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12935 background extension.
12937 2011-05-10 Jim Meyering <meyering@redhat.com>
12939 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12941 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12943 * image.c (Finit_image_library): Return t for built-in image types,
12944 like pbm and xbm. (Bug#8640)
12946 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12948 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12950 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12952 * w32console.c (Fset_screen_color): Doc fix.
12953 (Fget_screen_color): New function.
12954 (syms_of_ntterm): Defsubr it.
12956 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12957 unlink the temporary file if Fcall_process didn't create it in the
12959 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12960 child process will be redirected to a file specified with `:file'.
12961 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12962 cue to call_process_cleanup not to close that handle.
12964 2011-05-07 Ben Key <bkey76@gmail.com>
12966 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12967 one of two shell specific rules, either bootstrap-temacs-CMD or
12968 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12969 to the previous implementation of the bootstrap-temacs rule.
12970 The bootstrap-temacs-CMD rule is similar to the previous
12971 implementation of the bootstrap-temacs rule except that it
12972 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12975 These changes, along with some changes to nt/configure.bat,
12976 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12977 earlier fix to add support for --cflags and --ldflags options
12978 that include quotes so that it works whether make uses cmd or
12981 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12983 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12984 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12986 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12987 a string. Handle both cases.
12988 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12989 (Fdbus_register_method): Use Qinvalid_function.
12991 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12993 * makefile.w32-in: Update dependencies.
12994 (LISP_H): Add inttypes.h and stdin.h.
12995 (PROCESS_H): Add unistd.h.
12997 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12999 * lread.c: Include limits.h (fixes the MS-Windows build broken by
13000 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
13002 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
13004 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
13006 * term.c (vfatal): Remove stray call to va_end.
13007 It's not needed and the C Standard doesn't allow it here anyway.
13009 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
13010 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
13012 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
13015 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
13017 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13019 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
13021 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
13023 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
13025 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
13026 * charset.c (Fdefine_charset_internal): Don't initialize
13027 charset.code_space[15]. The value was garbage, on hosts with
13028 32-bit int (Bug#8600).
13030 * lread.c (read_integer): Be more consistent with string-to-number.
13031 Use string_to_number to do the actual conversion; this avoids
13032 rounding errors and fixes some other screwups. Without this fix,
13033 for example, #x1fffffffffffffff was misread as -2305843009213693952.
13034 (digit_to_number): Move earlier, for benefit of read_integer.
13035 Return -1 if the digit is out of range for the base, -2 if it is
13036 not a digit in any supported base. (Bug#8602)
13038 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13040 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13041 to match comment at start of function. This also removes a
13042 GCC warning about overflow in a 32+64-bit port.
13044 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
13046 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
13047 Reported by Stefan Monnier in
13048 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
13049 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13050 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
13052 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
13053 (EMACS_UINTPTR): Likewise, with uintptr_t.
13055 * lisp.h: Prefer 64-bit EMACS_INT if available.
13056 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
13057 on 32-bit hosts that have 64-bit int, so that they can access
13059 However, temporarily disable this change unless the temporary
13060 symbol WIDE_EMACS_INT is defined.
13062 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
13064 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
13065 This removes an assumption that EMACS_INT and long are the same
13066 width as pointers. The assumption is true for Emacs porting targets
13067 now, but we want to make other targets possible.
13068 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
13069 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
13070 In the rest of the code, change types of integers that hold casted
13071 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
13072 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
13073 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
13074 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
13075 No need to cast type when ORing.
13076 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
13077 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
13078 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
13079 assume EMACS_INT is the same width as char *.
13080 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
13081 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
13082 Remove no-longer-needed casts.
13083 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
13084 (xg_tool_bar_help_callback, xg_make_tool_item):
13085 Use EMACS_INTPTR to hold an integer
13086 that will be cast to void *; this can avoid a GCC warning
13087 if EMACS_INT is not the same width as void *.
13088 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
13089 * xdisp.c (display_echo_area_1, resize_mini_window_1):
13090 (current_message_1, set_message_1):
13091 Use a local to convert to proper width without a cast.
13092 * xmenu.c (dialog_selection_callback): Likewise.
13094 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
13095 Also, don't assume VALBITS / RAND_BITS is less than 5,
13096 and don't rely on undefined behavior when shifting a 1 left into
13098 * lisp.h (get_random): Change signature to match.
13100 * lread.c (hash_string): Use size_t, not int, for hash computation.
13101 Normally we prefer signed values; but hashing is special, because
13102 it's better to use unsigned division on hash table sizes so that
13103 the remainder is nonnegative. Also, size_t is the natural width
13104 for hashing into memory. The previous code used 'int', which doesn't
13105 retain enough info to hash well into very large tables.
13106 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
13108 * dbusbind.c: Don't possibly lose pointer info when converting.
13109 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13110 Use XPNTR rather than XHASH, so that the high-order bits of
13111 the pointer aren't lost when converting through void *.
13113 * eval.c (Fautoload): Don't double-shift a pointer.
13115 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
13117 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
13119 * gnutls.c (DEF_GNUTLS_FN):
13120 * image.c (DEF_IMGLIB_FN): Make function pointers static.
13122 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
13124 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
13127 2011-05-05 Eli Zaretskii <eliz@gnu.org>
13129 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
13130 New version that can reserve upto 2GB of heap space.
13132 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
13134 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
13136 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
13138 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
13139 `gnutls_certificate_set_x509_key_file'.
13141 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

13144 Update dependencies.
13146 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13148 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
13149 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
13150 Remove unused parameter `fildes'.
13151 * process.c (read_process_output, send_process): Don't pass it.
13153 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13155 Fix previous change: the library cache is defined in w32.c.
13156 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
13157 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
13159 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13161 Implement dynamic loading of GnuTLS on Windows.
13163 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
13164 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
13165 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):

13177 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
13178 (Fgnutls_available_p): New function.
13179 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

13189 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
13191 * w32.c (QCloaded_from, Vlibrary_cache): Define.
13192 (w32_delayed_load): Move from image.c. When loading a library, record
13193 its filename in the :loaded-from property of the library id.
13194 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
13195 Initialize and staticpro them.
13196 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
13198 * process.c: Include lisp.h before w32.h, not after.
13199 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
13200 instead of gnutls_record_check_pending.
13202 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
13204 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
13206 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
13207 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
13210 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
13212 * xterm.c (x_set_frame_alpha): Do not set property on anything
13213 else than FRAME_X_OUTER_WINDOW (Bug#8608).
13215 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
13217 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
13219 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
13221 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
13222 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

13228 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)

13231 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
13233 * callproc.c: Indentation fixup.
13235 * sysdep.c (wait_for_termination_1): Make static.
13236 (wait_for_termination, interruptible_wait_for_termination):
13237 Move after wait_for_termination_1.
13239 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
13241 * sysdep.c (interruptible_wait_for_termination): New function
13242 which is like wait_for_termination, but allows keyboard
13245 * callproc.c (Fcall_process): Add (:file "file") as an option for
13247 (Fcall_process_region): Ditto.
13249 2011-04-30 Eli Zaretskii <eliz@gnu.org>
13251 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
13252 rather than `XVECTOR (FOO)->size'.
13254 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
13255 inttypes.h, as a gnulib replacement is used if it not available in
13258 2011-04-21 Eli Zaretskii <eliz@gnu.org>
13260 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
13261 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
13262 of MOST_POSITIVE_FIXNUM. (Bug#8528)
13264 * coding.c (coding_alloc_by_realloc): Error out if destination
13265 will grow beyond MOST_POSITIVE_FIXNUM.
13266 (decode_coding_emacs_mule): Abort if there isn't enough place in
13267 charbuf for the composition carryover bytes. Reserve an extra
13268 space for up to 2 characters produced in a loop.
13269 (decode_coding_iso_2022): Abort if there isn't enough place in
13270 charbuf for the composition carryover bytes.
13272 2011-04-21 Eli Zaretskii <eliz@gnu.org>
13274 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
13275 aborting when %lld or %lll format is passed.
13276 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
13277 %llo or %llx format is passed. (Bug#8545)
13279 * window.c (window_scroll_line_based): Use a marker instead of
13280 simple variables to record original value of point. (Bug#7952)
13282 * doprnt.c (doprnt): Fix the case where a multibyte sequence
13283 produced by %s or %c overflows available buffer space. (Bug#8545)
13285 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
13287 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

13290 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
13292 * w32.c (init_environment): Warn about defaulting HOME to C:\.

13296 * keyboard.c (Qdelayed_warnings_hook): Define.
13297 (command_loop_1): Run `delayed-warnings-hook'
13298 if Vdelayed_warnings_list is non-nil.
13299 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
13300 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
13302 2011-04-28 Eli Zaretskii <eliz@gnu.org>
13304 * doprnt.c (doprnt): Don't return value smaller than the buffer
13305 size if the message was truncated. (Bug#8545).
13307 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
13309 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
13310 (Fx_window_property): #if-0 the whole functions, not just the bodies.
13312 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
13314 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
13316 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
13318 * makefile.w32-in: Update dependencies.
13320 2011-04-27 Eli Zaretskii <eliz@gnu.org>
13322 Improve `doprnt' and its usage. (Bug#8545)
13323 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
13324 `format_end'. Remove support for %l as a conversion specifier.
13325 Don't use xrealloc. Improve diagnostics when the %l size modifier
13326 is used. Update the commentary.
13328 * eval.c (verror): Simplify calculation of size_t.
13330 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
13333 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
13335 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
13338 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
13340 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
13341 This makes this file independent of the recent pseudovector change.
13343 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
13345 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
13347 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
13348 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
13349 Remove unused local.
13350 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
13352 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
13353 GCC 4.6.0 optimizes based on type-based alias analysis.
13354 For example, if b is of type struct buffer * and v of type struct
13355 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
13356 != &v->size, and therefore "v->size = 1; b->size = 2; return
13357 v->size;" must therefore return 1. This assumption is incorrect
13358 for Emacs, since it type-puns struct Lisp_Vector * with many other
13359 types. To fix this problem, this patch adds a new type struct
13360 vectorlike_header that documents the constraints on layout of vectors
13361 and pseudovectors, and helps optimizing compilers not get fooled
13362 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
13363 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
13364 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
13366 (XSETPVECTYPE): Rewrite in terms of new macro.
13367 (XSETPVECTYPESIZE): New macro, specifying both type and size.
13368 This is a bit clearer, and further avoids the possibility of
13369 undesirable aliasing.
13370 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
13371 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
13372 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
13373 since Lisp_Subr is a special case (no "next" field).
13374 (ASIZE): Now uses header.size rather than size.
13375 All previous uses of XVECTOR (foo)->size replaced to use this macro,
13376 to avoid the hassle of writing XVECTOR (foo)->header.size.
13377 (struct vectorlike_header): New type.
13378 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
13379 object, to help avoid aliasing.
13380 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
13381 (SUBRP): Likewise, since Lisp_Subr is a special case.
13382 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
13383 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
13384 (struct Lisp_Hash_Table): Combine first two members into a single
13385 struct vectorlike_header member. All uses of "size" and "next" members
13386 changed to be "header.size" and "header.next".
13387 * buffer.h (struct buffer): Likewise.
13388 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
13389 * frame.h (struct frame): Likewise.
13390 * process.h (struct Lisp_Process): Likewise.
13391 * termhooks.h (struct terminal): Likewise.
13392 * window.c (struct save_window_data, struct saved_window): Likewise.
13393 * window.h (struct window): Likewise.
13394 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
13395 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
13396 * buffer.c (init_buffer_once): Likewise.
13397 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
13399 * process.c (Fformat_network_address): Use local var for size,
13402 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
13404 Make the Lisp reader and string-to-float more consistent (Bug#8525)
13405 * data.c (atof): Remove decl; no longer used or needed.
13406 (digit_to_number): Move to lread.c.
13407 (Fstring_to_number): Use new string_to_number function, to be
13408 consistent with how the Lisp reader treats infinities and NaNs.
13409 Do not assume that floating-point numbers represent EMACS_INT
13410 without losing information; this is not true on most 64-bit hosts.
13411 Avoid double-rounding errors, by insisting on integers when
13412 parsing non-base-10 numbers, as the documentation specifies.
13413 * lisp.h (string_to_number): New decl, replacing ...
13414 (isfloat_string): Remove.
13415 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
13416 (read1): Do not accept +. and -. as integers; this
13417 appears to have been a coding error. Similarly, do not accept
13418 strings like +-1e0 as floating point numbers. Do not report
13419 overflow for integer overflows unless the base is not 10 which
13420 means we have no simple and reliable way to continue.
13421 Break out the floating-point parsing into a new
13422 function string_to_number, so that Fstring_to_number parses
13423 floating point numbers consistently with the Lisp reader.
13424 (digit_to_number): Move here from data.c. Make it static inline.
13425 (E_CHAR, EXP_INT): Remove, replacing with ...
13426 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
13427 (string_to_number): New function, replacing isfloat_string.
13428 This function checks for valid syntax and produces the resulting
13429 Lisp float number too. Rework it so that string-to-number
13430 no longer mishandles examples like "1.0e+". Use strtoumax,
13431 so that overflow for non-base-10 numbers is reported only when
13432 there's no portable and simple way to convert to floating point.
13434 * textprop.c (set_text_properties_1): Rewrite for clarity,
13435 and to avoid GCC warning about integer overflow.
13437 * intervals.h (struct interval): Use EMACS_INT for members
13438 where EMACS_UINT might cause problems. See
13439 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
13440 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
13441 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
13443 (offset_intervals): Tell GCC not to worry about length overflow
13444 when negating a negative length.
13446 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
13447 (overrun_check_free): Likewise.
13449 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
13450 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
13453 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13454 (gnutls_make_error): Rename local to avoid shadowing.
13455 (gnutls_emacs_global_deinit): ifdef out; not used.
13456 (Fgnutls_boot): Use const for pointer to readonly storage.
13457 Comment out unused local. Fix pointer signedness problems.
13459 * lread.c (openp): Don't stuff size_t into an 'int'.
13460 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
13461 about possible signed overflow.
13463 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13464 (GDK_KEY_g): Don't define if already defined.
13465 (xg_prepare_tooltip): Avoid pointer signedness problem.
13466 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
13468 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
13469 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
13471 * xfns.c (Fx_window_property): Simplify a bit,
13472 to make a bit faster and to avoid GCC 4.6.0 warning.
13473 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
13475 * fns.c (internal_equal): Don't assume size_t fits in int.
13477 * alloc.c (compact_small_strings): Tighten assertion a little.
13479 Replace pEd with more-general pI, and fix some printf arg casts.
13480 * lisp.h (pI): New macro, generalizing old pEd macro to other
13481 conversion specifiers. For example, use "...%"pI"d..." rather
13482 than "...%"pEd"...".
13483 (pEd): Remove. All uses replaced with similar uses of pI.
13484 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
13485 * alloc.c (check_pure_size): Don't overflow by converting size to int.
13486 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
13487 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
13488 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
13489 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
13490 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13492 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13493 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13494 * print.c (safe_debug_print, print_object): Likewise.
13495 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13497 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13498 avoiding the 0 flag, which is not portable.
13499 * process.c (Fmake_network_process): Use pI to avoid cast.
13500 * region-cache.c (pp_cache): Likewise.
13501 * xdisp.c (decode_mode_spec): Likewise.
13502 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13503 behavior on 64-bit hosts with printf arg.
13504 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13505 (x_stop_queuing_selection_requests): Likewise.
13506 (x_get_window_property): Don't truncate byte count to an 'int'
13509 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13510 here, since it parses constructs like leading '-' and spaces,
13511 which are not wanted; and it overflows with large numbers.
13512 Instead, simply match F[0-9]+, which is what is wanted anyway.
13514 * alloc.c: Remove unportable assumptions about struct layout.
13515 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13516 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13517 (allocate_vectorlike, make_pure_vector): Use the new macros,
13518 plus offsetof, to remove unportable assumptions about struct layout.
13519 These assumptions hold on all porting targets that I know of, but
13520 they are not guaranteed, they're easy to remove, and removing them
13521 makes further changes easier.
13523 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13524 This doesn't fix a bug but makes the code clearer.
13525 (string_overrun_cookie): Now const. Use initializers that
13526 don't formally overflow signed char, to avoid warnings.
13527 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13528 can cause Emacs to crash when string overrun checking is enabled.
13529 (allocate_buffer): Don't assume sizeof (struct buffer) is a
13530 multiple of sizeof (EMACS_INT); it need not be, if
13531 alignof(EMACS_INT) < sizeof (EMACS_INT).
13532 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
13534 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

13563 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
13564 "cast to pointer from integer of different size".
13566 Improve doprnt and its use in verror. (Bug#8545)
13567 * doprnt.c (doprnt): Document the set of format control sequences
13568 supported by the function. Use SAFE_ALLOCA instead of always
13571 * eval.c (verror): Don't limit the buffer size at size_max-1, that
13572 is one byte too soon. Don't use xrealloc; instead xfree and

13583 parameters of `gnutls-boot' and documented those parameters in the
13584 docstring. Start callback support.
13585 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
13586 unless a fatal error occurred. Call gnutls_alert_send_appropriate

13684 * callint.c (Fcall_interactively): When displaying error message
13685 about invalid control letter, pass the character's codepoint, not

13690 codepoint of an invalid character, to avoid displaying a bogus
13693 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
13694 `error', not SYMBOL_NAME itself.
13696 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
13697 character arguments to `error'.
13699 * charset.c (check_iso_charset_parameter): Fix incorrect argument
13700 to `error' in error message about FINAL_CHAR argument. Make sure
13701 FINAL_CHAR is a character, and use %c when it is passed as
13702 argument to `error'.
13704 2011-04-23 Eli Zaretskii <eliz@gnu.org>
13706 * s/ms-w32.h (localtime): Redirect to sys_localtime.
13708 * w32.c: Include <time.h>.

13766 Define only if needed.
13768 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
13769 by pacifying GCC about it. Maybe it's time to retire it?
13770 * xfaces.c (USG, __TIMEVAL__): Likewise.
13772 * dispextern.h (struct redisplay_interface): Rename param
13773 to avoid shadowing.
13774 * termhooks.h (struct terminal): Likewise.
13775 * xterm.c (xembed_send_message): Likewise.

13891 * nsfont.m: Fixed bugs in ns_get_family and
13892 ns_descriptor_to_entity that were caused by using free to
13893 deallocate memory blocks that were allocated by xmalloc (via
13894 xstrdup). This caused Emacs to crash when compiled with
13895 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13896 --enable-checking=xmallocoverrun). xfree is now used to
13897 deallocate these memory blocks.
13899 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
13901 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

13911 (emacs_read, emacs_write): Remove check for negative size, as the
13912 Emacs source code has been audited now.
13913 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
13914 (emacs_read, emacs_write): Use it.
13915 * process.c (send_process): Adjust to the new signatures of
13916 emacs_write and emacs_gnutls_write. Do not attempt to store
13917 a byte offset into an 'int'; it might overflow.
13918 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

13942 * font.c (Qopentype): Don't make static (used from w32uniscribe.c).
13944 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
13946 Improve C-level modularity by making more things 'static'.

14360 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
14362 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
14365 2011-04-13 Eli Zaretskii <eliz@gnu.org>
14367 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
14368 when at ZV. (Bug#8487)
14370 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
14372 * charset.c (Fclear_charset_maps): Use xfree instead of free.
14374 * keyboard.c (parse_tool_bar_item): Likewise.
14375 * sound.c (sound_cleanup, alsa_close): Likewise.
14376 * termcap.c (tgetent): Likewise.
14377 * xfns.c (x_default_font_parameter): Likewise.
14378 * xsettings.c (read_and_apply_settings): Likewise.
14380 * alloc.c (overrun_check_malloc, overrun_check_realloc)
14381 (overrun_check_free): Protoize.
14383 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
14385 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
14386 since callers should never pass a negative size.
14387 Change the signature to match that of plain 'read' and 'write'; see
14388 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
14389 * lisp.h: Update prototypes of emacs_write and emacs_read.
14391 2011-04-11 Eli Zaretskii <eliz@gnu.org>
14393 * xdisp.c (redisplay_window): Don't try to determine the character
14394 position of the scroll margin if the window start point w->startp
14395 is outside the buffer's accessible region. (Bug#8468)
14397 2011-04-10 Eli Zaretskii <eliz@gnu.org>
14399 Fix write-region and its subroutines for buffers > 2GB.
14400 * fileio.c (a_write, e_write): Modify declaration of arguments and
14401 local variables to support buffers larger than 2GB.
14402 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
14404 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
14405 argument, local variables, and return value.
14407 * lisp.h: Update prototypes of emacs_write and emacs_read.
14409 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
14411 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
14413 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
14415 Fix more problems found by GCC 4.6.0's static checks.
14417 * xdisp.c (vmessage): Use a better test for character truncation.
14419 * charset.c (load_charset_map): <, not <=, for optimization,
14420 and to avoid potential problems with integer overflow.
14421 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
14422 * casetab.c (set_identity, shuffle): Likewise.
14423 * editfns.c (Fformat): Likewise.
14424 * syntax.c (skip_chars): Likewise.
14426 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
14427 This also lets GCC 4.6.0 generate slightly better loop code.
14429 * callint.c (Fcall_interactively): <, not <=, for optimization.
14430 (Fcall_interactively): Count the number of arguments produced,
14431 not the number of arguments given. This is simpler and lets GCC
14432 4.6.0 generate slightly better code.
14434 * ftfont.c: Distingish more carefully between FcChar8 and char.
14435 The previous code passed unsigned char * to a functions like
14436 strlen and xstrcasecmp that expect char *, which does not
14437 conform to the C standard.
14438 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
14439 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
14440 char * when the C standard requires it.
14442 * keyboard.c (read_char): Remove unused var.
14444 * eval.c: Port to Windows vsnprintf (Bug#8435).
14445 Include <limits.h>.
14446 (SIZE_MAX): Define if the headers do not.
14447 (verror): Do not give up if vsnprintf returns a negative count.
14448 Instead, grow the buffer. This ports to Windows vsnprintf, which
14449 does not conform to C99. Problem reported by Eli Zaretskii.
14450 Also, simplify the allocation scheme, by avoiding the need for
14451 calling realloc, and removing the ALLOCATED variable.
14453 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
14455 Remove invocations of doprnt, as Emacs now uses vsnprintf.
14456 But keep the doprint source code for now, as we might revamp it
14457 and use it again (Bug#8435).
14458 * lisp.h (doprnt): Remove.
14459 * Makefile.in (base_obj): Remove doprnt.o.
14460 * deps.mk (doprnt.o): Remove.
14462 error: Print 32- and 64-bit integers portably (Bug#8435).
14463 Without this change, on typical 64-bit hosts error ("...%d...", N)
14464 was used to print both 32- and 64-bit integers N, which relied on
14465 undefined behavior.
14466 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
14467 * lisp.h (error, verror): Mark as printf-like functions.
14468 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
14469 Report overflow in size calculations when allocating printf buffer.
14470 Do not truncate output string at its first null byte.
14471 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
14472 Truncate the output at a character boundary, since vsnprintf does not
14474 * charset.c (check_iso_charset_parameter): Convert internal
14475 character to string before calling 'error', since %c now has the
14477 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
14478 overflow when computing char to be passed to 'error'. Do not
14479 pass Lisp_Object to 'error'; pass the integer instead.
14480 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
14481 formatted with plain %d.
14483 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
14485 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
14487 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
14489 * xterm.c (x_catch_errors): Remove duplicate declaration.
14491 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14493 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14495 2011-04-10 Jim Meyering <meyering@redhat.com>
14497 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14498 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14499 return ssize_t not "int", and use size_t as the buffer length.
14500 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14501 * gnutls.h: Update declarations.
14502 * process.c (read_process_output): Use ssize_t, to match.
14503 (send_process): Likewise.
14505 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14507 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14509 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14511 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14512 Use unsigned char, to match FcChar8 type definition.
14514 * xterm.c (handle_one_xevent):
14515 * xmenu.c (create_and_show_popup_menu):
14516 * xselect.c (x_decline_selection_request)
14517 (x_reply_selection_request): Avoid type-punned deref of X events.
14519 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14521 Fix some uses of `int' instead of EMACS_INT.
14522 * search.c (string_match_1, fast_string_match)
14523 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
14524 (scan_buffer, find_next_newline_no_quit)
14525 (find_before_next_newline, search_command, Freplace_match)
14526 (Fmatch_data): Make some `int' variables be EMACS_INT.
14528 * xdisp.c (display_count_lines): 3rd argument and return value now
14529 EMACS_INT. All callers changed.
14530 (pint2hrstr): Last argument is now EMACS_INT.
14532 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
14533 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
14534 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
14535 (decode_coding_utf_16, decode_coding_emacs_mule)
14536 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
14537 (decode_coding_ccl, decode_coding_charset)
14538 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
14539 (decode_coding_iso_2022, decode_coding_emacs_mule)
14540 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
14541 <char_offset, last_offset>: Declare EMACS_INT.
14542 (encode_coding_utf_8, encode_coding_utf_16)
14543 (encode_coding_emacs_mule, encode_invocation_designation)
14544 (encode_designation_at_bol, encode_coding_iso_2022)
14545 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14546 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14548 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14549 (encode_invocation_designation): Last argument P_NCHARS is now
14551 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14552 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14554 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14557 * ccl.c (Fccl_execute_on_string): Declare some variables
14560 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
14562 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
14564 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
14566 * process.c (Fformat_network_address): Doc fix.
14568 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
14570 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
14572 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
14574 * keyboard.c (read_char): Call Lisp function help-form-show,
14575 instead of using internal_with_output_to_temp_buffer.
14576 (Qhelp_form_show): New var.
14577 (syms_of_keyboard): Use DEFSYM macro.
14579 * print.c (internal_with_output_to_temp_buffer): Function deleted.
14581 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
14583 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
14585 * process.c (Flist_processes): Remove to Lisp.
14586 (list_processes_1): Delete.
14588 2011-04-06 Eli Zaretskii <eliz@gnu.org>
14590 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
14592 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
14594 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
14596 Fix more problems found by GCC 4.6.0's static checks.
14598 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
14600 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
14602 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14604 * xdisp.c (vmessage): Mark as a printf-like function.
14606 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14608 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14610 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14611 printf-like functions.
14612 (tiff_load): Add casts to remove these marks before passing them
14613 to system-supplied API.
14615 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14617 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14618 This avoids several warnings with gcc -Wstrict-overflow.
14619 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14620 directly, rather than having caller test rule sign. This avoids
14621 some unnecessary tests.
14622 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14623 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14624 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14626 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14627 (xfont_open): Avoid unnecessary tests.
14629 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14631 * composite.h, composite.c (composition_gstring_put_cache):
14632 Use EMACS_INT, not int, for length.

14635 breaking out part of COMPOSITION_DECODE_RULE.
14636 (COMPOSITION_DECODE_RULE): Use it.
14637 * composite.c (get_composition_id): Remove unused local vars,
14638 by using the new macro.
14640 * textprop.c (set_text_properties_1): Change while to do-while,
14641 since the condition is always true at first.
14643 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14644 (interval_deletion_adjustment): Return unsigned value.
14647 * process.c (list_processes_1, create_pty, read_process_output):
14648 (exec_sentinel): Remove vars that were set but not used.
14649 (create_pty): Remove unnecessary "volatile"s.
14650 (Fnetwork_interface_info): Avoid possibility of int overflow.

14657 (update_syntax_table): Use unsigned instead of int.
14659 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14660 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14661 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14663 * print.c (print_error_message): Avoid int overflow.
14665 * font.c (font_list_entities): Redo for clarity,
14666 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14668 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14669 (font_score): Avoid potential overflow in diff calculation.
14671 * fns.c (substring_both): Remove var that is set but not used.
14672 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14674 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14676 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14677 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14678 can always succeed if overflow has undefined behavior.
14680 * search.c (boyer_moore, wordify): Remove vars set but not used.
14681 (wordify): Omit three unnecessary tests.
14683 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14684 All callers changed. This avoids the need for an unused var.
14686 * casefiddle.c (casify_region): Remove var that is set but not used.
14688 * dired.c (file_name_completion): Remove var that is set but not used.
14690 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14692 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14693 (Finsert_file_contents): Remove unnecessary code checking fd.
14695 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14696 Check for integer overflow on size calculations.
14698 * buffer.c (Fprevious_overlay_change): Remove var that is set
14701 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14702 Remove vars that are set but not used.
14703 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14704 (timer_check_2): Mark vars as initialized.
14706 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14708 * image.c (lookup_image): Remove var that is set but not used.
14709 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14711 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14712 that are set but not used.
14714 * xfns.c (make_invisible_cursor): Don't return garbage
14715 if XCreateBitmapFromData fails (Bug#8410).
14717 * xselect.c (x_get_local_selection, x_handle_property_notify):
14718 Remove vars that are set but not used.
14720 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14721 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

14730 (map_tty_color) [!defined MSDOS]: Likewise.
14732 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14734 * coding.c: Remove vars that are set but not used.
14735 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14736 All callers changed.
14737 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14738 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
14739 (decode_coding_charset): Remove vars that are set but not used.
14741 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14742 that is set but not used.
14744 * print.c (print_object): Remove var that is set but not used.
14746 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14747 The gnulib version avoids calling malloc in the usual case,
14748 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14749 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14750 * filelock.c (current_lock_owner): Likewise.
14751 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14752 * sysdep.c: Include allocator.h, careadlinkat.h.
14753 (emacs_no_realloc_allocator): New static constant.
14754 (emacs_readlink): New function.
14755 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14756 ../lib/careadlinkat.h.
14758 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14760 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14761 first non-nil return value).
14763 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
14765 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14766 if not defined (Bug#8403).
14768 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14770 * xdisp.c (display_count_lines): Remove parameter `start',
14771 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

14775 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14776 and thereabouts. All callers changed.
14777 (get_per_char_metric): Remove parameter `f', unused since
14778 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14780 2011-04-02 Jim Meyering <meyering@redhat.com>
14782 do not dereference NULL upon failed strdup
14783 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14784 (ns_get_family): Likewise.
14786 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14788 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
14790 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
14792 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

14808 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
14810 (syms_of_lread): Declare `lexical-binding'.
14812 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
14814 * keyboard.c (eval_dyn): New fun.
14815 (menu_item_eval_property): Use it.
14817 * image.c (parse_image_spec): Use Ffunctionp.
14819 * fns.c (concat, mapcar1): Accept byte-code-functions.
14821 * eval.c (Fsetq): Handle lexical vars.
14822 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
14823 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14824 (FletX, Flet): Obey lexical binding.
14825 (Fcommandp): Handle closures.
14826 (Feval): New `lexical' arg.
14827 (eval_sub): New function extracted from Feval. Use it almost
14828 everywhere where Feval was used. Look up vars in lexical env.
14830 (Ffunctionp): Move from subr.el.
14831 (Ffuncall): Handle closures.
14832 (apply_lambda): Remove `eval_flags'.
14833 (funcall_lambda): Handle closures and new byte-code-functions.
14834 (Fspecial_variable_p): New function.
14835 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14836 but without exporting it to Lisp.
14838 * doc.c (Fdocumentation, store_function_docstring):
14839 * data.c (Finteractive_form): Handle closures.
14841 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14844 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14846 (exec_byte_code): New function extracted from Fbyte_code to handle new
14847 calling convention for byte-code-functions. Add new byte-codes.
14849 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14851 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14853 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14855 * xdisp.c (redisplay_internal): Fix prototype.
14857 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14859 * xdisp.c (SCROLL_LIMIT): New macro.
14860 (try_scrolling): Use it when setting scroll_limit.
14861 Limit scrolling to 100 screen lines.
14862 (redisplay_window): Even when falling back on "recentering",
14863 position point in the window according to scroll-conservatively,
14864 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14866 (try_scrolling): When point is above the window, allow searching
14867 as far as scroll_max, or one screenful, to compute vertical
14868 distance from PT to the scroll margin position. This prevents
14869 try_scrolling from unnecessarily failing when
14870 scroll-conservatively is set to a value slightly larger than the
14871 window height. Clean up the case of PT below the margin at bottom
14872 of window: scroll_max can no longer be INT_MAX. When aggressive
14873 scrolling is in use, don't let point enter the opposite scroll
14874 margin as result of the scroll.
14875 (syms_of_xdisp) <scroll-conservatively>: Document the
14876 threshold of 100 lines for never-recentering scrolling.
14878 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14880 * dispextern.h (move_it_by_lines):
14881 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14882 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14883 (message_log_check_duplicate): Remove parameters `prev_bol' and
14884 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14885 (redisplay_internal): Remove parameter `preserve_echo_area',
14886 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14888 * indent.c (Fvertical_motion):
14889 * window.c (window_scroll_pixel_based, Frecenter):
14890 Don't pass `need_y_p' to `move_it_by_lines'.
14892 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14894 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14895 steal a few bits to be more compact.
14896 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14897 Remove unneeded casts.
14899 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14901 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14903 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14904 binding" message (bug#7967).
14906 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14908 Fix more problems found by GCC 4.6.0's static checks.
14910 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14911 Remove unused local var.
14913 * editfns.c (Fmessage_box): Remove unused local var.
14915 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14916 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14917 Omit unused local vars.
14918 * window.c (shrink_windows): Omit unused local var.
14919 * menu.c (digest_single_submenu): Omit unused local var.
14920 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14921 Omit unused local var.
14923 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14924 Don't assume string length fits in int.
14925 (keyremap_step, read_key_sequence): Use size_t for sizes.
14926 (read_key_sequence): Don't check last_real_key_start redundantly.
14928 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14929 instead of alloca (Bug#8344).
14931 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14932 (Fbacktrace_frame): Don't assume nframes fits in int.
14934 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14936 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14939 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14941 * cm.c (calccost): Turn while-do into do-while, for clarity.
14943 * keyboard.c (syms_of_keyboard): Use the same style as later
14944 in this function when indexing through an array. This also
14945 works around GCC bug 48267.
14947 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14949 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14951 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14952 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14954 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14955 This avoids undefined behavior on integer overflow, and is a bit
14956 more convenient anyway since it is compared to a size_t variable.
14958 Variadic C functions now count arguments with size_t, not int.
14959 This avoids an unnecessary limitation on 64-bit machines, which
14960 caused (substring ...) to crash on large vectors (Bug#8344).
14961 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14962 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14963 All variadic functions and their callers changed accordingly.
14964 (struct gcpro.nvars): Now size_t, not int. All uses changed.
14965 * data.c (arith_driver, float_arith_driver): Likewise.
14966 * editfns.c (general_insert_function): Likewise.
14967 * eval.c (struct backtrace.nargs, interactive_p)
14968 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14969 (funcall_lambda, mark_backtrace): Likewise.
14970 * fns.c (concat): Likewise.
14971 * frame.c (x_set_frame_parameters): Likewise.
14972 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14973 0 if not found, not -1. All callers changed.
14975 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14976 (stack_copy_size): Now size_t, not int.
14977 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14979 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14981 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14982 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14983 All callers changed.
14985 * lisp.h (multibyte_char_to_unibyte):
14986 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14987 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14988 * character.h (CHAR_TO_BYTE8):
14989 * cmds.c (internal_self_insert):
14990 * editfns.c (general_insert_function):
14991 * keymap.c (push_key_description):
14992 * search.c (Freplace_match):
14993 * xdisp.c (message_dolog, set_message_1): All callers changed.
14995 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14997 * keyboard.c (safe_run_hook_funcall): New function.
14998 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14999 don't set the hook to nil, but remove the offending function instead.
15000 (Qcommand_hook_internal): Remove, unused.
15001 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
15002 Vcommand_hook_internal.
15004 * eval.c (enum run_hooks_condition): Remove.
15005 (funcall_nil, funcall_not): New functions.
15006 (run_hook_with_args): Call each function through a `funcall' argument.
15007 Remove `cond' argument, now redundant.
15008 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
15009 (Frun_hook_with_args_until_failure): Adjust accordingly.
15010 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
15012 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
15014 * dispextern.h (string_buffer_position): Remove declaration.
15016 * print.c (strout): Remove parameter `multibyte', unused since
15017 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
15019 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
15020 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
15021 All callers changed.
15023 * w32.c (_wsa_errlist): Use braces for struct initializers.
15025 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
15026 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
15027 All callers changed.
15028 (string_buffer_position): Likewise. Also, make static (it's never
15029 used outside xdisp.c).
15030 (cursor_row_p): Remove parameter `w', unused since
15031 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

15033 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
15034 All callers changed.
15036 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
15038 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
15040 2011-03-27 Anders Lindgren <andlind@gmail.com>
15042 * nsterm.m (ns_menu_bar_is_hidden): New variable.
15043 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
15044 (ns_update_auto_hide_menu_bar): New functions.
15045 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
15046 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and
15047 ns_constrain_all_frames.

15049 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
15051 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
15053 * nsmenu.m (runDialogAt): Remove argument to timer_check.
15055 2011-03-27 Glenn Morris <rgm@gnu.org>
15057 * syssignal.h: Replace RETSIGTYPE with void.
15058 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
15059 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
15060 Replace SIGTYPE with void everywhere.
15061 * s/usg5-4-common.h (SIGTYPE): Remove definition.
15062 * s/template.h (SIGTYPE): Remove commented out definition.
15064 2011-03-26 Eli Zaretskii <eliz@gnu.org>
15066 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
15067 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
15069 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
15071 * w32.c (read_unc_volume): Use parameter `henum', instead of
15072 global variable `wget_enum_handle'.
15074 * keymap.c (describe_vector): Remove parameters `indices' and
15075 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
15076 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
15078 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
15080 * keyboard.c (timer_check): Remove parameter `do_it_now',
15081 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
15082 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
15083 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
15085 * keyboard.c (read_char):
15086 * w32menu.c (w32_menu_display_help):
15087 * xmenu.c (show_help_event, menu_help_callback):
15088 Adjust calls to `show_help_echo'.
15090 * gtkutil.c (xg_maybe_add_timer):
15091 * keyboard.c (readable_events):
15092 * process.c (wait_reading_process_output):
15093 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
15095 * insdel.c (adjust_markers_gap_motion):
15096 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
15097 (gap_left, gap_right): Don't call it.
15099 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
15101 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
15102 incurred during fontification.

15143 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
15145 * w32term.c (x_set_glyph_string_clipping):
15146 Don't pass uninitialized region to CombineRgn.
15148 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
15150 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
15151 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
15152 (Fx_close_connection): Remove unused variable `i'.
15154 * w32font.c (w32font_draw): Return number of glyphs.
15155 (w32font_open_internal): Remove unused variable `i'.

15168 (uniscribe_font_driver): Add missing initializers.
15170 2011-03-23 Julien Danjou <julien@danjou.info>
15172 * term.c (Fsuspend_tty, Fresume_tty):
15173 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
15174 * window.c (temp_output_buffer_show):
15175 * insdel.c (signal_before_change):
15176 * frame.c (Fhandle_switch_frame):
15177 * fileio.c (Fdo_auto_save):
15178 * emacs.c (Fkill_emacs):
15179 * editfns.c (save_excursion_restore):
15180 * cmds.c (internal_self_insert):
15181 * callint.c (Fcall_interactively):
15182 * buffer.c (Fkill_all_local_variables):
15183 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
15185 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
15186 unconditionally since it does the check itself.
15188 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
15190 Fix more problems found by GCC 4.5.2's static checks.
15192 * coding.c (encode_coding_raw_text): Avoid unnecessary test
15193 the first time through the loop, since we know p0 < p1 then.
15194 This also avoids a gcc -Wstrict-overflow warning.
15196 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
15197 leading to a memory leak, possible in functions like
15198 load_charset_map_from_file that can allocate an unbounded number
15199 of objects (Bug#8318).
15201 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
15202 that could (at least in theory) be that large.
15204 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
15205 This is less likely to overflow, and avoids undefined behavior if
15206 overflow does occur. All callers changed. Use strtoul to scan
15207 for the unsigned long integer.
15208 (pint2hrstr): Simplify and tune code slightly.
15209 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
15211 * scroll.c (do_scrolling): Work around GCC bug 48228.
15212 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
15214 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
15215 This also avoids a warning with gcc -Wstrict-overflow.
15216 (validate_x_resource_name): Simplify count usage.
15217 This also avoids a warning with gcc -Wstrict-overflow.
15219 * fileio.c (Fcopy_file): Report error if fchown or fchmod
15222 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
15224 * process.c (Fmake_network_process): Use socklen_t, not int,
15225 where POSIX says socklen_t is required in portable programs.
15226 This fixes a porting bug on hosts like 64-bit HP-UX, where
15227 socklen_t is wider than int (Bug#8277).
15228 (Fmake_network_process, server_accept_connection):
15229 (wait_reading_process_output, read_process_output):
15232 * process.c: Rename or move locals to avoid shadowing.
15233 (list_processes_1, Fmake_network_process):
15234 (read_process_output_error_handler, exec_sentinel_error_handler):
15235 Rename or move locals.
15236 (Fmake_network_process): Define label "retry_connect" only if needed.
15237 (Fnetwork_interface_info): Fix pointer signedness.
15238 (process_send_signal): Add cast to avoid pointer signedness problem.
15239 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
15240 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
15242 Make tparam.h and terminfo.c consistent.
15243 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
15244 Include tparam.h instead, since it declares them.

15304 clobbering (Bug#8298).
15305 * sysdep.c (sys_subshell): Likewise.
15306 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
15308 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
15309 This should get cleaned up, so that child_setup has the
15310 same signature on all platforms.
15312 * callproc.c (call_process_cleanup): Now static.
15313 (relocate_fd): Rename locals to avoid shadowing.

15484 to use the following functions instead of these macros.
15485 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
15486 EMACS_INT, since callers assume the returned value fits in int.

15500 (RETALLOC_IF): Define only if needed.
15501 (WORDCHAR_P): Likewise. This one is never needed, but is used
15502 only in a comment talking about a compiler bug, so put inside
15503 the #if 0 of that comment.
15504 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15505 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15533 gcpro1, gcpro2, etc.
15534 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15536 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15537 argument, for consistency with GCPRO2_VAR, etc: it is now the
15538 prefix of the variable, not the variable itself. All uses
15540 * dired.c (directory_files_internal, file_name_completion):
15541 Rename locals to avoid shadowing.
15543 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15544 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15545 dired.c's scmp function, had undefined behavior.
15546 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15547 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15548 * buffer.h: ... to here, because these macros use current_buffer,
15549 and the new implementation with inline functions needs to have
15550 current_buffer in scope now, rather than later when the macros
15552 (downcase, upcase1): New static inline functions.
15553 (DOWNCASE, UPCASE1): Reimplement using these functions.
15554 This avoids undefined behavior in expressions like
15555 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15556 from race conditions in accessing the global variables
15557 case_temp1 and case_temp2.
15558 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15559 * lisp.h (case_temp1, case_temp2): Remove their decls.
15560 * character.h (ASCII_CHAR_P): Move from here ...

15573 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15575 (Fset_file_times, Finsert_file_contents, auto_save_error):

15585 so that gcc does not warn that these functions aren't declared.

15588 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

15595 * buffer.c (fix_overlays_before): Mark locals as initialized.
15596 (fix_start_end_in_overlays): Likewise. This function should be
15597 simplified by using pointers-to-pointers, but that's a different

15600 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15601 (report_overlay_modification): Rename locals to avoid shadowing.

15607 (MAXPATHLEN): Define only if needed.
15609 * process.c (serial_open, serial_configure): Move decls from here ...
15610 * systty.h: ... to here, so that they can be checked.
15612 * fns.c (get_random, seed_random): Move extern decls from here ...
