1 2011-06-14 Paul Eggert <eggert@cs.ucla.edu>
3 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
4 * mem-limits.h (SIZE): Remove; no longer used.
6 2011-06-13 Paul Eggert <eggert@cs.ucla.edu>
8 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10 Remove unnecessary casts.
11 * xterm.c (x_term_init):
12 * xfns.c (x_set_border_pixel):
13 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14 These aren't needed now that we assume ANSI C.
16 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17 It's more likely to cause problems (due to unsigned overflow)
20 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
22 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
24 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
26 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
28 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
30 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
32 GLYPH_CODE_FACE returns EMACS_INT, not int.
33 * dispextern.h (merge_faces):
34 * xfaces.c (merge_faces):
35 * xdisp.c (get_next_display_element, next_element_from_display_vector):
36 Don't assume EMACS_INT fits in int.
38 * character.h (CHAR_VALID_P): Remove unused parameter.
39 * fontset.c, lisp.h, xdisp.c: All uses changed.
41 * editfns.c (Ftranslate_region_internal): Omit redundant test.
43 * fns.c (concat): Minor tuning based on overflow analysis.
44 This doesn't fix any bugs. Use int to hold character, instead
45 of constantly refetching from Emacs object. Use XFASTINT, not
46 XINT, for value known to be a character. Don't bother comparing
47 a single byte to 0400, as it's always less.
50 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
52 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
55 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
57 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
58 Without this fix, on a 64-bit host (aset S 0 4294967386) would
59 incorrectly succeed when S was a string, because 4294967386 was
60 truncated before it was used.
62 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
63 Otherwise, an out-of-range integer could cause undefined behavior
66 * composite.c: Use int, not EMACS_INT, for characters.
67 (fill_gstring_body, composition_compute_stop_pos): Use int, not
68 EMACS_INT, for values that are known to be in character range.
69 This doesn't fix any bugs but is the usual style inside Emacs and
70 may generate better code on 32-bit machines.
72 Make sure a 64-bit char is never passed to ENCODE_CHAR.
73 This is for reasons similar to the recent CHAR_STRING fix.
74 * charset.c (Fencode_char): Check that character arg is actually
75 a character. Pass an int to ENCODE_CHAR.
76 * charset.h (ENCODE_CHAR): Verify that the character argument is no
77 wider than 'int', as a compile-time check to prevent future regressions
80 * character.c (char_string): Remove unnecessary casts.
82 Make sure a 64-bit char is never passed to CHAR_STRING.
83 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
84 by silently ignoring the top 32 bits, allowing some values
85 that were far too large to be valid characters.
86 * character.h: Include <verify.h>.
87 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
88 arguments are no wider than unsigned, as a compile-time check
89 to prevent future regressions in this area.
91 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
92 (Fsubst_char_in_region):
94 * xdisp.c (decode_mode_spec_coding):
95 Adjust to CHAR_STRING's new requirement.
96 * editfns.c (Finsert_char, Fsubst_char_in_region):
97 * fns.c (concat): Check that character args are actually
98 characters. Without this test, these functions did the wrong
99 thing with wildly out-of-range values on 64-bit hosts.
101 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
102 These casts should not be needed on 32-bit hosts, either.
103 * keyboard.c (read_char):
104 * lread.c (Fload): Remove casts to unsigned.
106 * lisp.h (UNSIGNED_CMP): New macro.
107 This fixes comparison bugs on 64-bit hosts.
108 (ASCII_CHAR_P): Use it.
109 * casefiddle.c (casify_object):
110 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
111 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
112 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
113 * dispextern.h (FACE_FROM_ID):
114 * keyboard.c (read_char): Use UNSIGNED_CMP.
116 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
117 not to EMACS_INT, to avoid GCC warning.
119 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
121 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
122 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
123 isn't needed on 32-bit machines.
125 * buffer.c (Fgenerate_new_buffer_name):
126 Use EMACS_INT for count, not int.
127 (advance_to_char_boundary): Return EMACS_INT, not int.
129 * data.c (Qcompiled_function): Now static.
131 * window.c (window_body_lines): Now static.
133 * image.c (gif_load): Rename local to avoid shadowing.
135 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
136 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
137 * alloc.c (make_save_value): Integer argument is now of type
139 (mark_object): Use ptrdiff_t, not int.
140 * lisp.h (pD): New macro.
141 * print.c (print_object): Use it.
143 * alloc.c: Use EMACS_INT, not int, to count objects.
144 (total_conses, total_markers, total_symbols, total_vector_size)
145 (total_free_conses, total_free_markers, total_free_symbols)
146 (total_free_floats, total_floats, total_free_intervals)
147 (total_intervals, total_strings, total_free_strings):
148 Now EMACS_INT, not int. All uses changed.
149 (Fgarbage_collect): Compute overall total using a double, so that
150 integer overflow is less likely to be a problem. Check for overflow
151 when converting back to an integer.
152 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
153 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
154 These were 'int' variables that could overflow on 64-bit hosts;
155 they were never used, so remove them instead of repairing them.
156 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
157 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
158 Previously, this ceilinged at INT_MAX, but that doesn't work on
160 (allocate_pseudovector): Don't use EMACS_INT when int would do.
162 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
163 (allocate_vectorlike): Check for ptrdiff_t overflow.
164 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
165 when a (possibly-narrower) signed value would do just as well.
166 We prefer using signed arithmetic, to avoid comparison confusion.
168 * alloc.c: Catch some string size overflows that we were missing.
169 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
170 for convenience in STRING_BYTES_MAX.
171 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
172 The definition here is exact; the one in lisp.h was approximate.
173 (allocate_string_data): Check for string overflow. This catches
174 some instances we weren't catching before. Also, it catches
175 size_t overflow on (unusual) hosts where SIZE_MAX <= min
176 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
177 and ptrdiff_t and EMACS_INT are both 64 bits.
179 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
180 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
181 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
183 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
185 * alloc.c (Fmake_string): Check for out-of-range init.
187 2011-06-12 Martin Rudalics <rudalics@gmx.at>
189 * frame.c (make_frame): Call other_buffer_safely instead of
192 * window.c (temp_output_buffer_show): Call display_buffer with

222 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
223 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
224 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
225 the same widths as pointers. This follows up on the 2011-05-06 patch.
226 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
228 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

796 runs afoul of improving memory_full behavior. (Bug#8761)
797 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
798 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
799 xfree instead of the default malloc, realloc, free.
800 (Fgnutls_boot): No need to check for memory allocation failure,
801 since xmalloc does that for us.

835 (SXHASH_REDUCE): New macro.
836 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
837 Use it instead of discarding useful hash info with large hash values.
838 (sxhash_float): New function.
839 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
840 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
841 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
842 Rewrite to use FIXNUM_BITS, as this simplifies things.
843 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
844 Adjust signatures to match updated version of code.
845 (consing_since_gc): Now EMACS_INT, since a single hash table can
846 use more than INT_MAX bytes.

898 syms_of_callproc does the same thing. Remove test for
899 "initialized", do it in the caller.
900 * emacs.c (main): Avoid calling set_initial_environment when dumping.
902 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>

977 that was so large that it became a float. (Bug#8722)
979 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
980 (Fdbus_call_method, Fdbus_call_method_asynchronously):
981 Use XFASTINT rather than XUINT when numbers are nonnegative.
982 (xd_append_arg, Fdbus_method_return_internal):
983 (Fdbus_method_error_internal): Likewise. Also, for unsigned
984 arguments, check that Lisp number is nonnegative, rather than
985 silently wrapping negative numbers around. (Bug#8722)
986 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
989 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
991 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
993 ccl: add integer overflow checks
994 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
995 (IN_INT_RANGE): New macros.
996 (ccl_driver): Use them to check for integer overflow when
997 decoding a CCL program. Many of the new checks are whether XINT (x)
998 fits in int; it doesn't always, on 64-bit hosts. The new version
999 doesn't catch all possible integer overflows, but it's an
1000 improvement. (Bug#8719)
1002 * alloc.c (make_event_array): Use XINT, not XUINT.
1003 There's no need for unsigned here.
1005 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1006 This follows up to the 2011-05-06 change that substituted uintptr_t
1007 for EMACS_INT. This case wasn't caught back then.
1009 Rework Fformat to avoid integer overflow issues.
1010 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1011 now (part of C89). Include <verify.h>.
1012 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1013 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1014 (Fformat): Avoid the prepass trying to compute sizes; it was only
1015 approximate and thus did not catch overflow reliably. Instead, walk
1016 through the format just once, formatting and computing sizes as we go,
1017 checking for integer overflow at every step, and allocating a larger
1018 buffer as needed. Keep track separately whether the format is
1019 multibyte. Keep only the most-recently calculated precision, rather
1020 than them all. Record whether each argument has been converted to
1021 string. Use EMACS_INT, not int, for byte and char and arg counts.
1022 Support field widths and precisions larger than INT_MAX. Avoid
1023 sprintf's undefined behavior with conversion specifications such as %#d
1024 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1025 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1026 formatting out-of-range floating point numbers with int
1029 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1031 * data.c: Avoid integer truncation in expressions involving floats.
1032 * data.c: Include <intprops.h>.
1033 (arith_driver): When there's an integer overflow in an expression
1034 involving floating point, convert the integers to floating point
1035 so that the resulting value does not suffer from catastrophic
1036 integer truncation. For example, on a 64-bit host (* 4
1037 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1038 Do not rely on undefined behavior after integer overflow.
1040 merge count_size_as_multibyte, parse_str_to_multibyte
1041 * character.c, character.h (count_size_as_multibyte):
1042 Rename from parse_str_to_multibyte; all uses changed.
1043 Check for integer overflow.
1044 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1045 since it's now a duplicate of the other. This is more of
1046 a character than a buffer op, so better that it's in character.c.
1047 * fns.c, print.c: Adjust to above changes.
1049 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1051 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1053 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1055 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1056 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1057 (x_clipboard_manager_save): Now static.
1058 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1060 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1061 (crypto_hash_function): Now static.
1062 Fix pointer signedness problems. Avoid unnecessary initializations.
1064 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1066 * termhooks.h (Vselection_alist): Make it terminal-local.
1068 * terminal.c (create_terminal): Initialize it.
1070 * xselect.c: Support for clipboard managers.
1071 (Vselection_alist): Move to termhooks.h as terminal-local var.
1072 (LOCAL_SELECTION): New macro.
1073 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1074 (symbol_to_x_atom): Remove gratuitous arg.
1075 (x_handle_selection_request, lisp_data_to_selection_data)
1076 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1077 (x_own_selection, x_get_local_selection, x_convert_selection):
1078 New arg, specifying work frame. Use terminal-local Vselection_alist.
1079 (some_frame_on_display): Delete unused function.
1080 (Fx_own_selection_internal, Fx_get_selection_internal)
1081 (Fx_disown_selection_internal, Fx_selection_owner_p)
1082 (Fx_selection_exists_p): New optional frame arg.
1083 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1084 (x_handle_selection_clear): Don't treat other terminals with the
1085 same keyboard specially. Use the terminal-local Vselection_alist.
1086 (x_clear_frame_selections): Use Frun_hook_with_args.
1088 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1090 * xterm.h: Add support for those atoms.
1092 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1094 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1095 (converted_selections, conversion_fail_tag): New global variables.
1096 (x_selection_request_lisp_error): Free the above.
1097 (x_get_local_selection): Remove unnecessary code.
1098 (x_reply_selection_request): Args changed; handle arbitrary array
1099 of converted selections stored in converted_selections.
1100 Separate the XChangeProperty and SelectionNotify steps.
1101 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1102 (x_convert_selection): New function.
1103 (x_handle_selection_event): Simplify.
1104 (x_get_foreign_selection): Don't ignore incoming requests while
1105 waiting for an answer; this will fail when we implement
1106 SAVE_TARGETS, and seems unnecessary anyway.
1107 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1108 (Vx_sent_selection_functions): Doc fix.
1110 2011-05-26 Leo Liu <sdl.web@gmail.com>
1112 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1114 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1116 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1118 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1119 for fringe update if it has periodic bitmap.
1120 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1121 and fringe_bitmap_periodic_p.
1123 * fringe.c (get_fringe_bitmap_data): New function.
1124 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1125 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1126 row. Mark glyph row for fringe update if periodicity changed.
1128 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1129 for fringe update unless it has periodic bitmap.
1131 2011-05-25 Kenichi Handa <handa@m17n.org>
1133 * xdisp.c (get_next_display_element): Set correct it->face_id for
1134 a static composition.
1136 2011-05-24 Leo Liu <sdl.web@gmail.com>
1139 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1141 * fns.c (crypto_hash_function, Fsha1): New function.
1142 (Fmd5): Use crypto_hash_function.
1143 (syms_of_fns): Add Ssha1.
1145 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1147 * gnutls.c: Remove unused macros.
1148 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1149 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1150 Remove macros that are defined and never used.
1151 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1153 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1155 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1156 (Fx_get_selection_internal): Minor cleanup.
1157 (Fx_own_selection_internal): Rename arguments for consistency with
1160 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1162 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1164 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1166 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1168 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1170 * dispnew.c (scrolling_window): Don't exclude the case that the
1171 last enabled row in the desired matrix touches the bottom boundary.
1173 2011-05-21 Glenn Morris <rgm@gnu.org>
1175 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1176 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1177 and add some more files.
1179 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1181 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1182 report_file_error introduced by the change from 2011-05-07.
1184 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1186 * systime.h (Time): Define only if emacs is defined.
1187 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1188 where the include path doesn't have X11/X.h by default. See
1189 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1191 2011-05-20 Kenichi Handa <handa@m17n.org>
1193 * composite.c (find_automatic_composition): Fix previous change.
1195 2011-05-20 Glenn Morris <rgm@gnu.org>
1197 * lisp.mk: New file, split from Makefile.in.
1198 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1199 (shortlisp): Remove.
1200 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1202 2011-05-19 Glenn Morris <rgm@gnu.org>
1204 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1205 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1206 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1207 (lisp): Set the order to that of loadup.el.
1208 (shortlisp): Make it a copy of $lisp.
1209 (SOME_MACHINE_LISP): Remove.
1210 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1211 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1213 2011-05-18 Kenichi Handa <handa@m17n.org>
1215 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1216 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1217 (find_automatic_composition): Mostly rewrite for efficiency.
1219 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1221 * makefile.w32-in: Update dependencies.
1223 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1225 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1228 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1230 Fix some integer overflow issues, such as string length overflow.
1232 * insdel.c (count_size_as_multibyte): Check for string overflow.
1234 * character.c (lisp_string_width): Check for string overflow.
1235 Use EMACS_INT, not int, for string indexes and lengths; in
1236 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1237 the resulting string length overflows an EMACS_INT; instead,
1238 report a string overflow if no precision given. When checking for
1239 precision exhaustion, use a check that cannot possibly have
1240 integer overflow. (Bug#8675)
1241 * character.h (lisp_string_width): Adjust to new signature.
1243 * alloc.c (string_overflow): New function.
1244 (Fmake_string): Use it. This doesn't change behavior, but saves
1245 a few bytes and will simplify future changes.
1246 * character.c (string_escape_byte8): Likewise.
1247 * lisp.h (string_overflow): New decl.
1249 Fixups, following up to the user-interface timestamp change.
1250 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1251 for UI timestamps, instead of unsigned long.
1252 * msdos.c (mouse_get_pos): Likewise.
1253 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1254 * w32gui.h (Time): Define by including "systime.h" rather than by
1255 declaring it ourselves. (Bug#8664)
1257 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1258 * image.c (clear_image_cache): Likewise.
1260 * term.c (term_mouse_position): Don't assume time_t wraparound.
1262 Be more systematic about user-interface timestamps.
1263 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1264 and sometimes 'EMACS_UINT', to represent these timestamps.
1265 This change causes it to use 'Time' uniformly, as that's what X uses.
1266 This makes the code easier to follow, and makes it easier to catch
1267 integer overflow bugs such as Bug#8664.
1268 * frame.c (Fmouse_position, Fmouse_pixel_position):
1269 Use Time, not unsigned long, for user-interface timestamps.
1270 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1271 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1272 * keyboard.h (last_event_timestamp): Likewise.
1273 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1274 * menu.h (xmenu_show): Likewise.
1275 * term.c (term_mouse_position): Likewise.
1276 * termhooks.h (struct input_event.timestamp): Likewise.
1277 (struct terminal.mouse_position_hook): Likewise.
1278 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1279 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1280 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1281 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1283 * menu.h, termhooks.h: Include "systime.h", for Time.
1285 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1286 Don't assume that the difference between two unsigned long values
1287 can fit into an integer. At this point, we know button_down_time
1288 <= event->timestamp, so the difference must be nonnegative, so
1289 there's no need to cast the result if double-click-time is
1290 nonnegative, as it should be; check that it's nonnegative, just in
1291 case. This bug is triggered when events are more than 2**31 ms
1292 apart (about 25 days). (Bug#8664)
1294 * xselect.c (last_event_timestamp): Remove duplicate decl.
1295 (x_own_selection): Remove needless cast to unsigned long.
1297 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1298 that always fit in int. Use a sentinel instead of a counter, to
1299 avoid a temp and to allay GCC's concerns about possible int overflow.
1300 * frame.h (struct frame): Use int for menu_bar_items_used
1301 instead of EMACS_INT, since it always fits in int.
1303 * menu.c (grow_menu_items): Check for int overflow.
1305 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1307 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1308 Before, the code was not consistent. These values cannot exceed
1309 2**31 - 1 so there's no need to make them unsigned.
1310 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1311 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1312 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1314 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1316 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1317 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1318 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1319 presumably because the widths might not match.
1321 * window.c (size_window): Avoid needless test at loop start.
1323 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1325 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1327 2011-05-12 Drew Adams <drew.adams@oracle.com>
1329 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1331 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1333 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1334 `width' to `bar_area_x' and `bar_area_width', respectively.
1335 (x_scroll_run): Take account of fringe background extension.
1337 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1338 Rename local vars `left' and `width' to `bar_area_x' and
1339 `bar_area_width', respectively.
1340 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1341 background extension.
1343 2011-05-10 Jim Meyering <meyering@redhat.com>
1345 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1347 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1349 * image.c (Finit_image_library): Return t for built-in image types,
1350 like pbm and xbm. (Bug#8640)
1352 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1354 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1356 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1358 * w32console.c (Fset_screen_color): Doc fix.
1359 (Fget_screen_color): New function.
1360 (syms_of_ntterm): Defsubr it.
1362 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1363 unlink the temporary file if Fcall_process didn't create it in the
1365 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1366 child process will be redirected to a file specified with `:file'.
1367 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1368 cue to call_process_cleanup not to close that handle.
1370 2011-05-07 Ben Key <bkey76@gmail.com>
1372 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1373 one of two shell specific rules, either bootstrap-temacs-CMD or
1374 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1375 to the previous implementation of the bootstrap-temacs rule.
1376 The bootstrap-temacs-CMD rule is similar to the previous
1377 implementation of the bootstrap-temacs rule except that it
1378 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1381 These changes, along with some changes to nt/configure.bat,
1382 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1383 earlier fix to add support for --cflags and --ldflags options
1384 that include quotes so that it works whether make uses cmd or
1387 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1389 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1390 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1392 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1393 a string. Handle both cases.
1394 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1395 (Fdbus_register_method): Use Qinvalid_function.
1397 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1399 * makefile.w32-in: Update dependencies.
1400 (LISP_H): Add inttypes.h and stdin.h.
1401 (PROCESS_H): Add unistd.h.
1403 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1405 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1406 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1408 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1410 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1412 * term.c (vfatal): Remove stray call to va_end.
1413 It's not needed and the C Standard doesn't allow it here anyway.
1415 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
1416 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
1418 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
1421 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
1423 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1425 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
1427 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
1429 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
1431 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
1432 * charset.c (Fdefine_charset_internal): Don't initialize
1433 charset.code_space[15]. The value was garbage, on hosts with
1434 32-bit int (Bug#8600).
1436 * lread.c (read_integer): Be more consistent with string-to-number.
1437 Use string_to_number to do the actual conversion; this avoids
1438 rounding errors and fixes some other screwups. Without this fix,
1439 for example, #x1fffffffffffffff was misread as -2305843009213693952.
1440 (digit_to_number): Move earlier, for benefit of read_integer.
1441 Return -1 if the digit is out of range for the base, -2 if it is
1442 not a digit in any supported base. (Bug#8602)
1444 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
1446 * dispnew.c (scrolling_window): Return 1 if we scrolled,
1447 to match comment at start of function. This also removes a
1448 GCC warning about overflow in a 32+64-bit port.
1450 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
1452 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
1453 Reported by Stefan Monnier in
1454 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
1455 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1456 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
1458 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
1459 (EMACS_UINTPTR): Likewise, with uintptr_t.
1461 * lisp.h: Prefer 64-bit EMACS_INT if available.
1462 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
1463 on 32-bit hosts that have 64-bit int, so that they can access
1465 However, temporarily disable this change unless the temporary
1466 symbol WIDE_EMACS_INT is defined.
1468 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
1470 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
1471 This removes an assumption that EMACS_INT and long are the same
1472 width as pointers. The assumption is true for Emacs porting targets
1473 now, but we want to make other targets possible.
1474 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
1475 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
1476 In the rest of the code, change types of integers that hold casted
1477 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
1478 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
1479 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
1480 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
1481 No need to cast type when ORing.
1482 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
1483 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
1484 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
1485 assume EMACS_INT is the same width as char *.
1486 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
1487 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
1488 Remove no-longer-needed casts.
1489 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
1490 (xg_tool_bar_help_callback, xg_make_tool_item):
1491 Use EMACS_INTPTR to hold an integer
1492 that will be cast to void *; this can avoid a GCC warning
1493 if EMACS_INT is not the same width as void *.
1494 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
1495 * xdisp.c (display_echo_area_1, resize_mini_window_1):
1496 (current_message_1, set_message_1):
1497 Use a local to convert to proper width without a cast.
1498 * xmenu.c (dialog_selection_callback): Likewise.
1500 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
1501 Also, don't assume VALBITS / RAND_BITS is less than 5,
1502 and don't rely on undefined behavior when shifting a 1 left into
1504 * lisp.h (get_random): Change signature to match.
1506 * lread.c (hash_string): Use size_t, not int, for hash computation.
1507 Normally we prefer signed values; but hashing is special, because
1508 it's better to use unsigned division on hash table sizes so that
1509 the remainder is nonnegative. Also, size_t is the natural width
1510 for hashing into memory. The previous code used 'int', which doesn't
1511 retain enough info to hash well into very large tables.
1512 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
1514 * dbusbind.c: Don't possibly lose pointer info when converting.
1515 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1516 Use XPNTR rather than XHASH, so that the high-order bits of
1517 the pointer aren't lost when converting through void *.
1519 * eval.c (Fautoload): Don't double-shift a pointer.
1521 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
1523 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1525 * gnutls.c (DEF_GNUTLS_FN):
1526 * image.c (DEF_IMGLIB_FN): Make function pointers static.
1528 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
1530 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
1533 2011-05-05 Eli Zaretskii <eliz@gnu.org>
1535 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
1536 New version that can reserve upto 2GB of heap space.
1538 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
1540 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
1542 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
1544 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
1545 `gnutls_certificate_set_x509_key_file'.
1547 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
1549 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
1550 Update dependencies.
1552 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1554 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
1555 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
1556 Remove unused parameter `fildes'.
1557 * process.c (read_process_output, send_process): Don't pass it.
1559 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1561 Fix previous change: the library cache is defined in w32.c.
1562 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
1563 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
1565 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1567 Implement dynamic loading of GnuTLS on Windows.
1569 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
1570 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
1571 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
1574 * gnutls.c (Qgnutls_dll): Define.
1575 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
1576 (gnutls_*): Declare function pointers.
1577 (init_gnutls_functions): New function to initialize function pointers.
1578 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
1579 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
1580 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
1581 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
1582 (emacs_gnutls_write, emacs_gnutls_read)
1583 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
1584 (Fgnutls_available_p): New function.
1585 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
1586 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
1587 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
1589 * image.c: Include w32.h.
1590 (Vimage_type_cache): Delete.
1591 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
1592 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
1593 (w32_delayed_load): Move to w32.c.
1595 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
1597 * w32.c (QCloaded_from, Vlibrary_cache): Define.
1598 (w32_delayed_load): Move from image.c. When loading a library, record
1599 its filename in the :loaded-from property of the library id.
1600 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
1601 Initialize and staticpro them.
1602 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
1604 * process.c: Include lisp.h before w32.h, not after.
1605 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
1606 instead of gnutls_record_check_pending.
1608 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
1610 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
1612 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
1613 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
1616 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
1618 * xterm.c (x_set_frame_alpha): Do not set property on anything
1619 else than FRAME_X_OUTER_WINDOW (Bug#8608).
1621 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
1623 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
1625 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
1627 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
1628 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
1629 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

1634 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
1635 (Qgnutls_bootprop_callbacks_verify): Make static.
1637 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
1639 * callproc.c: Indentation fixup.
1641 * sysdep.c (wait_for_termination_1): Make static.
1642 (wait_for_termination, interruptible_wait_for_termination):
1643 Move after wait_for_termination_1.
1645 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
1647 * sysdep.c (interruptible_wait_for_termination): New function
1648 which is like wait_for_termination, but allows keyboard
1651 * callproc.c (Fcall_process): Add (:file "file") as an option for
1653 (Fcall_process_region): Ditto.
1655 2011-04-30 Eli Zaretskii <eliz@gnu.org>
1657 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
1658 rather than `XVECTOR (FOO)->size'.
1660 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
1661 inttypes.h, as a gnulib replacement is used if it not available in
1664 2011-04-21 Eli Zaretskii <eliz@gnu.org>
1666 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
1667 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
1668 of MOST_POSITIVE_FIXNUM. (Bug#8528)
1670 * coding.c (coding_alloc_by_realloc): Error out if destination
1671 will grow beyond MOST_POSITIVE_FIXNUM.
1672 (decode_coding_emacs_mule): Abort if there isn't enough place in
1673 charbuf for the composition carryover bytes. Reserve an extra
1674 space for up to 2 characters produced in a loop.
1675 (decode_coding_iso_2022): Abort if there isn't enough place in
1676 charbuf for the composition carryover bytes.
1678 2011-04-21 Eli Zaretskii <eliz@gnu.org>
1680 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
1681 aborting when %lld or %lll format is passed.
1682 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
1683 %llo or %llx format is passed. (Bug#8545)
1685 * window.c (window_scroll_line_based): Use a marker instead of
1686 simple variables to record original value of point. (Bug#7952)
1688 * doprnt.c (doprnt): Fix the case where a multibyte sequence
1689 produced by %s or %c overflows available buffer space. (Bug#8545)
1691 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
1693 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
1694 (SIZE_MAX): Move defn after all includes, as they might #define it.
1696 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1698 * w32.c (init_environment): Warn about defaulting HOME to C:\.
1700 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1702 * keyboard.c (Qdelayed_warnings_hook): Define.
1703 (command_loop_1): Run `delayed-warnings-hook'
1704 if Vdelayed_warnings_list is non-nil.
1705 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
1706 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
1708 2011-04-28 Eli Zaretskii <eliz@gnu.org>
1710 * doprnt.c (doprnt): Don't return value smaller than the buffer
1711 size if the message was truncated. (Bug#8545).
1713 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1715 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
1716 (Fx_window_property): #if-0 the whole functions, not just the bodies.
1718 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1720 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
1722 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
1724 * makefile.w32-in: Update dependencies.
1726 2011-04-27 Eli Zaretskii <eliz@gnu.org>
1728 Improve `doprnt' and its usage. (Bug#8545)
1729 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
1730 `format_end'. Remove support for %l as a conversion specifier.
1731 Don't use xrealloc. Improve diagnostics when the %l size modifier
1732 is used. Update the commentary.
1734 * eval.c (verror): Simplify calculation of size_t.
1736 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
1739 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
1741 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
1744 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1746 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
1747 This makes this file independent of the recent pseudovector change.
1749 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
1751 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
1753 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
1754 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
1755 Remove unused local.
1756 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
1758 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
1759 GCC 4.6.0 optimizes based on type-based alias analysis.
1760 For example, if b is of type struct buffer * and v of type struct
1761 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
1762 != &v->size, and therefore "v->size = 1; b->size = 2; return
1763 v->size;" must therefore return 1. This assumption is incorrect
1764 for Emacs, since it type-puns struct Lisp_Vector * with many other
1765 types. To fix this problem, this patch adds a new type struct
1766 vectorlike_header that documents the constraints on layout of vectors
1767 and pseudovectors, and helps optimizing compilers not get fooled
1768 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
1769 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
1770 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
1772 (XSETPVECTYPE): Rewrite in terms of new macro.
1773 (XSETPVECTYPESIZE): New macro, specifying both type and size.
1774 This is a bit clearer, and further avoids the possibility of
1775 undesirable aliasing.
1776 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
1777 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
1778 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
1779 since Lisp_Subr is a special case (no "next" field).
1780 (ASIZE): Now uses header.size rather than size.
1781 All previous uses of XVECTOR (foo)->size replaced to use this macro,
1782 to avoid the hassle of writing XVECTOR (foo)->header.size.
1783 (struct vectorlike_header): New type.
1784 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
1785 object, to help avoid aliasing.
1786 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
1787 (SUBRP): Likewise, since Lisp_Subr is a special case.
1788 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
1789 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
1790 (struct Lisp_Hash_Table): Combine first two members into a single
1791 struct vectorlike_header member. All uses of "size" and "next" members
1792 changed to be "header.size" and "header.next".
1793 * buffer.h (struct buffer): Likewise.
1794 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
1795 * frame.h (struct frame): Likewise.
1796 * process.h (struct Lisp_Process): Likewise.
1797 * termhooks.h (struct terminal): Likewise.
1798 * window.c (struct save_window_data, struct saved_window): Likewise.
1799 * window.h (struct window): Likewise.
1800 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
1801 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
1802 * buffer.c (init_buffer_once): Likewise.
1803 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
1805 * process.c (Fformat_network_address): Use local var for size,
1808 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
1810 Make the Lisp reader and string-to-float more consistent (Bug#8525)
1811 * data.c (atof): Remove decl; no longer used or needed.
1812 (digit_to_number): Move to lread.c.
1813 (Fstring_to_number): Use new string_to_number function, to be
1814 consistent with how the Lisp reader treats infinities and NaNs.
1815 Do not assume that floating-point numbers represent EMACS_INT
1816 without losing information; this is not true on most 64-bit hosts.
1817 Avoid double-rounding errors, by insisting on integers when
1818 parsing non-base-10 numbers, as the documentation specifies.
1819 * lisp.h (string_to_number): New decl, replacing ...
1820 (isfloat_string): Remove.
1821 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
1822 (read1): Do not accept +. and -. as integers; this
1823 appears to have been a coding error. Similarly, do not accept
1824 strings like +-1e0 as floating point numbers. Do not report
1825 overflow for integer overflows unless the base is not 10 which
1826 means we have no simple and reliable way to continue.
1827 Break out the floating-point parsing into a new
1828 function string_to_number, so that Fstring_to_number parses
1829 floating point numbers consistently with the Lisp reader.
1830 (digit_to_number): Move here from data.c. Make it static inline.
1831 (E_CHAR, EXP_INT): Remove, replacing with ...
1832 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
1833 (string_to_number): New function, replacing isfloat_string.
1834 This function checks for valid syntax and produces the resulting
1835 Lisp float number too. Rework it so that string-to-number
1836 no longer mishandles examples like "1.0e+". Use strtoumax,
1837 so that overflow for non-base-10 numbers is reported only when
1838 there's no portable and simple way to convert to floating point.
1840 * textprop.c (set_text_properties_1): Rewrite for clarity,
1841 and to avoid GCC warning about integer overflow.
1843 * intervals.h (struct interval): Use EMACS_INT for members
1844 where EMACS_UINT might cause problems. See
1845 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
1846 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
1847 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
1849 (offset_intervals): Tell GCC not to worry about length overflow
1850 when negating a negative length.
1852 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
1853 (overrun_check_free): Likewise.
1855 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
1856 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
1859 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
1860 (gnutls_make_error): Rename local to avoid shadowing.
1861 (gnutls_emacs_global_deinit): ifdef out; not used.
1862 (Fgnutls_boot): Use const for pointer to readonly storage.
1863 Comment out unused local. Fix pointer signedness problems.
1865 * lread.c (openp): Don't stuff size_t into an 'int'.
1866 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
1867 about possible signed overflow.
1869 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
1870 (GDK_KEY_g): Don't define if already defined.
1871 (xg_prepare_tooltip): Avoid pointer signedness problem.
1872 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
1874 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
1875 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
1877 * xfns.c (Fx_window_property): Simplify a bit,
1878 to make a bit faster and to avoid GCC 4.6.0 warning.
1879 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
1881 * fns.c (internal_equal): Don't assume size_t fits in int.
1883 * alloc.c (compact_small_strings): Tighten assertion a little.
1885 Replace pEd with more-general pI, and fix some printf arg casts.
1886 * lisp.h (pI): New macro, generalizing old pEd macro to other
1887 conversion specifiers. For example, use "...%"pI"d..." rather
1888 than "...%"pEd"...".
1889 (pEd): Remove. All uses replaced with similar uses of pI.
1890 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
1891 * alloc.c (check_pure_size): Don't overflow by converting size to int.
1892 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
1893 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
1894 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
1895 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
1896 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
1898 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
1899 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
1900 * print.c (safe_debug_print, print_object): Likewise.
1901 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
1903 Use pI instead of if-then-else-abort. Use %p to avoid casts,
1904 avoiding the 0 flag, which is not portable.
1905 * process.c (Fmake_network_process): Use pI to avoid cast.
1906 * region-cache.c (pp_cache): Likewise.
1907 * xdisp.c (decode_mode_spec): Likewise.

1912 (x_get_window_property): Don't truncate byte count to an 'int'
1915 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
1916 here, since it parses constructs like leading '-' and spaces,
1917 which are not wanted; and it overflows with large numbers.
1918 Instead, simply match F[0-9]+, which is what is wanted anyway.
1920 * alloc.c: Remove unportable assumptions about struct layout.
1921 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
1922 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
1923 (allocate_vectorlike, make_pure_vector): Use the new macros,
1924 plus offsetof, to remove unportable assumptions about struct layout.
1925 These assumptions hold on all porting targets that I know of, but
1926 they are not guaranteed, they're easy to remove, and removing them
1927 makes further changes easier.
1929 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
1930 This doesn't fix a bug but makes the code clearer.
1931 (string_overrun_cookie): Now const. Use initializers that
1932 don't formally overflow signed char, to avoid warnings.
1933 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
1934 can cause Emacs to crash when string overrun checking is enabled.
1935 (allocate_buffer): Don't assume sizeof (struct buffer) is a
1936 multiple of sizeof (EMACS_INT); it need not be, if
1937 alignof(EMACS_INT) < sizeof (EMACS_INT).
1938 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

1974 supported by the function. Use SAFE_ALLOCA instead of always
1977 * eval.c (verror): Don't limit the buffer size at size_max-1, that
1978 is one byte too soon. Don't use xrealloc; instead xfree and
1981 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
1983 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

1987 gnutls_global_initialized. Added internals for the
1988 :verify-hostname-error, :verify-error, and :verify-flags

2093 in octal and display also its hex code.
2095 * character.c (char_string): Use %x to display the (unsigned)
2096 codepoint of an invalid character, to avoid displaying a bogus
2099 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
2100 `error', not SYMBOL_NAME itself.
2102 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
2103 character arguments to `error'.
2105 * charset.c (check_iso_charset_parameter): Fix incorrect argument
2106 to `error' in error message about FINAL_CHAR argument. Make sure
2107 FINAL_CHAR is a character, and use %c when it is passed as
2108 argument to `error'.
2110 2011-04-23 Eli Zaretskii <eliz@gnu.org>

2298 ns_descriptor_to_entity that were caused by using free to
2299 deallocate memory blocks that were allocated by xmalloc (via
2300 xstrdup). This caused Emacs to crash when compiled with
2301 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
2302 --enable-checking=xmallocoverrun). xfree is now used to
2303 deallocate these memory blocks.

2319 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
2320 (emacs_read, emacs_write): Use it.
2321 * process.c (send_process): Adjust to the new signatures of
2322 emacs_write and emacs_gnutls_write. Do not attempt to store
2323 a byte offset into an 'int'; it might overflow.
2324 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html
2326 * sound.c: Don't assume sizes fit in 'int'.

2791 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
2792 since callers should never pass a negative size.
2793 Change the signature to match that of plain 'read' and 'write'; see
2794 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
2795 * lisp.h: Update prototypes of emacs_write and emacs_read.
2797 2011-04-11 Eli Zaretskii <eliz@gnu.org>
2799 * xdisp.c (redisplay_window): Don't try to determine the character
2800 position of the scroll margin if the window start point w->startp
2801 is outside the buffer's accessible region. (Bug#8468)
2803 2011-04-10 Eli Zaretskii <eliz@gnu.org>
2805 Fix write-region and its subroutines for buffers > 2GB.
2806 * fileio.c (a_write, e_write): Modify declaration of arguments and
2807 local variables to support buffers larger than 2GB.
2808 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
2810 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
2811 argument, local variables, and return value.
2813 * lisp.h: Update prototypes of emacs_write and emacs_read.
2815 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
2817 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
2819 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
2821 Fix more problems found by GCC 4.6.0's static checks.
2823 * xdisp.c (vmessage): Use a better test for character truncation.
2825 * charset.c (load_charset_map): <, not <=, for optimization,
2826 and to avoid potential problems with integer overflow.
2827 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
2828 * casetab.c (set_identity, shuffle): Likewise.
2829 * editfns.c (Fformat): Likewise.
2830 * syntax.c (skip_chars): Likewise.
2832 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
2833 This also lets GCC 4.6.0 generate slightly better loop code.
2835 * callint.c (Fcall_interactively): <, not <=, for optimization.
2836 (Fcall_interactively): Count the number of arguments produced,
2837 not the number of arguments given. This is simpler and lets GCC
2838 4.6.0 generate slightly better code.
2840 * ftfont.c: Distingish more carefully between FcChar8 and char.
2841 The previous code passed unsigned char * to a functions like
2842 strlen and xstrcasecmp that expect char *, which does not
2843 conform to the C standard.
2844 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
2845 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
2846 char * when the C standard requires it.
2848 * keyboard.c (read_char): Remove unused var.
2850 * eval.c: Port to Windows vsnprintf (Bug#8435).
2852 (SIZE_MAX): Define if the headers do not.
2853 (verror): Do not give up if vsnprintf returns a negative count.
2854 Instead, grow the buffer. This ports to Windows vsnprintf, which
2855 does not conform to C99. Problem reported by Eli Zaretskii.
2856 Also, simplify the allocation scheme, by avoiding the need for
2857 calling realloc, and removing the ALLOCATED variable.
2859 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
2861 Remove invocations of doprnt, as Emacs now uses vsnprintf.
2862 But keep the doprint source code for now, as we might revamp it
2863 and use it again (Bug#8435).
2864 * lisp.h (doprnt): Remove.
2865 * Makefile.in (base_obj): Remove doprnt.o.
2866 * deps.mk (doprnt.o): Remove.
2868 error: Print 32- and 64-bit integers portably (Bug#8435).
2869 Without this change, on typical 64-bit hosts error ("...%d...", N)
2870 was used to print both 32- and 64-bit integers N, which relied on
2872 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
2874 * lisp.h (error, verror): Mark as printf-like functions.
2875 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
2876 Report overflow in size calculations when allocating printf buffer.
2877 Do not truncate output string at its first null byte.
2878 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
2879 Truncate the output at a character boundary, since vsnprintf does not
2881 * charset.c (check_iso_charset_parameter): Convert internal
2882 character to string before calling 'error', since %c now has the
2884 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
2885 overflow when computing char to be passed to 'error'. Do not
2886 pass Lisp_Object to 'error'; pass the integer instead.
2887 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
2888 formatted with plain %d.
2890 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
2892 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
2894 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
2896 * xterm.c (x_catch_errors): Remove duplicate declaration.
2898 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
2900 * xdisp.c, lisp.h (message_nolog): Remove; unused.
2902 2011-04-10 Jim Meyering <meyering@redhat.com>
2904 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
2905 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
2906 return ssize_t not "int", and use size_t as the buffer length.
2907 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
2908 * gnutls.h: Update declarations.
2909 * process.c (read_process_output): Use ssize_t, to match.
2910 (send_process): Likewise.
2912 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
2914 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
2916 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
2918 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
2919 Use unsigned char, to match FcChar8 type definition.
2921 * xterm.c (handle_one_xevent):
2922 * xmenu.c (create_and_show_popup_menu):
2923 * xselect.c (x_decline_selection_request)
2924 (x_reply_selection_request): Avoid type-punned deref of X events.
2926 2011-04-09 Eli Zaretskii <eliz@gnu.org>
2928 Fix some uses of `int' instead of EMACS_INT.
2929 * search.c (string_match_1, fast_string_match)
2930 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
2931 (scan_buffer, find_next_newline_no_quit)
2932 (find_before_next_newline, search_command, Freplace_match)
2933 (Fmatch_data): Make some `int' variables be EMACS_INT.
2935 * xdisp.c (display_count_lines): 3rd argument and return value now
2936 EMACS_INT. All callers changed.
2937 (pint2hrstr): Last argument is now EMACS_INT.
2939 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
2940 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
2941 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
2942 (decode_coding_utf_16, decode_coding_emacs_mule)
2943 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
2944 (decode_coding_ccl, decode_coding_charset)
2945 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
2946 (decode_coding_iso_2022, decode_coding_emacs_mule)
2947 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
2948 <char_offset, last_offset>: Declare EMACS_INT.
2949 (encode_coding_utf_8, encode_coding_utf_16)
2950 (encode_coding_emacs_mule, encode_invocation_designation)
2951 (encode_designation_at_bol, encode_coding_iso_2022)
2952 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
2953 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
2955 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
2956 (encode_invocation_designation): Last argument P_NCHARS is now
2958 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
2959 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
2961 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
2964 * ccl.c (Fccl_execute_on_string): Declare some variables
2967 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
2969 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
2971 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>

2975 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
2977 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
2979 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
2981 * keyboard.c (read_char): Call Lisp function help-form-show,
2982 instead of using internal_with_output_to_temp_buffer.
2983 (Qhelp_form_show): New var.
2984 (syms_of_keyboard): Use DEFSYM macro.
2986 * print.c (internal_with_output_to_temp_buffer): Function deleted.
2988 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
2990 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
2992 * process.c (Flist_processes): Remove to Lisp.
2993 (list_processes_1): Delete.
2995 2011-04-06 Eli Zaretskii <eliz@gnu.org>
2997 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
2999 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
3001 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3003 Fix more problems found by GCC 4.6.0's static checks.
3005 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3007 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3009 * lisp.h (message, message_nolog, fatal): Mark as printf-like.

3013 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
3015 * sound.c (sound_warning): Don't crash if arg contains a printf format.

3018 printf-like functions.
3019 (tiff_load): Add casts to remove these marks before passing them
3020 to system-supplied API.
3022 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3024 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3025 This avoids several warnings with gcc -Wstrict-overflow.
3026 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3027 directly, rather than having caller test rule sign. This avoids
3028 some unnecessary tests.
3029 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3030 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3031 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3033 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3034 (xfont_open): Avoid unnecessary tests.
3036 * composite.c (composition_gstring_put_cache): Use unsigned integer.

3045 by using the new macro.
3047 * textprop.c (set_text_properties_1): Change while to do-while,
3048 since the condition is always true at first.

3063 * syntax.c (scan_words): Remove var that was set but not used.
3064 (update_syntax_table): Use unsigned instead of int.
3066 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

3075 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3076 (font_score): Avoid potential overflow in diff calculation.
3078 * fns.c (substring_both): Remove var that is set but not used.
3079 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3081 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3083 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3084 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3085 can always succeed if overflow has undefined behavior.
3087 * search.c (boyer_moore, wordify): Remove vars set but not used.
3088 (wordify): Omit three unnecessary tests.
3090 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3091 All callers changed. This avoids the need for an unused var.
3093 * casefiddle.c (casify_region): Remove var that is set but not used.
3095 * dired.c (file_name_completion): Remove var that is set but not used.
3097 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3099 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3100 (Finsert_file_contents): Remove unnecessary code checking fd.
3102 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3103 Check for integer overflow on size calculations.
3105 * buffer.c (Fprevious_overlay_change): Remove var that is set
3108 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3109 Remove vars that are set but not used.
3110 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3111 (timer_check_2): Mark vars as initialized.
3113 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3115 * image.c (lookup_image): Remove var that is set but not used.
3116 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3118 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3119 that are set but not used.
3121 * xfns.c (make_invisible_cursor): Don't return garbage
3122 if XCreateBitmapFromData fails (Bug#8410).

3142 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3143 All callers changed.
3144 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

3146 (decode_coding_charset): Remove vars that are set but not used.
3148 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3149 that is set but not used.
3151 * print.c (print_object): Remove var that is set but not used.
3153 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3154 The gnulib version avoids calling malloc in the usual case,
3155 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3156 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3157 * filelock.c (current_lock_owner): Likewise.
3158 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

3172 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3173 if not defined (Bug#8403).
3175 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3177 * xdisp.c (display_count_lines): Remove parameter `start',

3189 do not dereference NULL upon failed strdup
3190 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.

3269 (redisplay_window): Even when falling back on "recentering",
3270 position point in the window according to scroll-conservatively,
3271 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3273 (try_scrolling): When point is above the window, allow searching
3274 as far as scroll_max, or one screenful, to compute vertical
3275 distance from PT to the scroll margin position. This prevents
3276 try_scrolling from unnecessarily failing when
3277 scroll-conservatively is set to a value slightly larger than the
3278 window height. Clean up the case of PT below the margin at bottom
3279 of window: scroll_max can no longer be INT_MAX. When aggressive
3280 scrolling is in use, don't let point enter the opposite scroll
3281 margin as result of the scroll.
3282 (syms_of_xdisp) <scroll-conservatively>: Document the
3283 threshold of 100 lines for never-recentering scrolling.
3285 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3287 * dispextern.h (move_it_by_lines):
3288 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
3289 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
3290 (message_log_check_duplicate): Remove parameters `prev_bol' and
3291 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3292 (redisplay_internal): Remove parameter `preserve_echo_area',
3293 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3295 * indent.c (Fvertical_motion):
3296 * window.c (window_scroll_pixel_based, Frecenter):
3297 Don't pass `need_y_p' to `move_it_by_lines'.
3299 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3301 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
3302 steal a few bits to be more compact.
3303 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
3304 Remove unneeded casts.
3306 * bytecode.c (Fbyte_code): CAR and CDR can GC.
3308 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
3310 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
3311 binding" message (bug#7967).
3313 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3315 Fix more problems found by GCC 4.6.0's static checks.
3317 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3318 Remove unused local var.
3320 * editfns.c (Fmessage_box): Remove unused local var.
3322 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3323 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3324 Omit unused local vars.
3325 * window.c (shrink_windows): Omit unused local var.
3326 * menu.c (digest_single_submenu): Omit unused local var.
3327 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3328 Omit unused local var.
3330 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
3331 Don't assume string length fits in int.
3332 (keyremap_step, read_key_sequence): Use size_t for sizes.
3333 (read_key_sequence): Don't check last_real_key_start redundantly.
3335 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3336 instead of alloca (Bug#8344).
3338 * eval.c (Fbacktrace): Don't assume nargs fits in int.
3339 (Fbacktrace_frame): Don't assume nframes fits in int.
3341 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

3346 * term.c (produce_glyphless_glyph): Remove unnecessary test.
3348 * cm.c (calccost): Turn while-do into do-while, for clarity.
3350 * keyboard.c (syms_of_keyboard): Use the same style as later
3351 in this function when indexing through an array. This also
3352 works around GCC bug 48267.
3354 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3356 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
3358 * chartab.c (sub_char_table_ref_and_range): Redo for slight
3359 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3361 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3362 This avoids undefined behavior on integer overflow, and is a bit
3363 more convenient anyway since it is compared to a size_t variable.
3365 Variadic C functions now count arguments with size_t, not int.
3366 This avoids an unnecessary limitation on 64-bit machines, which
3367 caused (substring ...) to crash on large vectors (Bug#8344).
3368 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
3369 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
3370 All variadic functions and their callers changed accordingly.

3372 * data.c (arith_driver, float_arith_driver): Likewise.
3373 * editfns.c (general_insert_function): Likewise.
3374 * eval.c (struct backtrace.nargs, interactive_p)
3375 (internal_condition_case_n, run_hook_with_args, apply_lambda)
3376 (funcall_lambda, mark_backtrace): Likewise.
3377 * fns.c (concat): Likewise.
3378 * frame.c (x_set_frame_parameters): Likewise.
3379 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3380 0 if not found, not -1. All callers changed.
3382 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3383 (stack_copy_size): Now size_t, not int.
3384 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
3386 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
3388 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
3389 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3390 All callers changed.
3392 * lisp.h (multibyte_char_to_unibyte):
3393 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
3394 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3395 * character.h (CHAR_TO_BYTE8):
3396 * cmds.c (internal_self_insert):

3398 * keymap.c (push_key_description):
3399 * search.c (Freplace_match):
3400 * xdisp.c (message_dolog, set_message_1): All callers changed.
3402 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
3404 * keyboard.c (safe_run_hook_funcall): New function.
3405 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
3406 don't set the hook to nil, but remove the offending function instead.
3407 (Qcommand_hook_internal): Remove, unused.
3408 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
3409 Vcommand_hook_internal.
3411 * eval.c (enum run_hooks_condition): Remove.
3412 (funcall_nil, funcall_not): New functions.
3413 (run_hook_with_args): Call each function through a `funcall' argument.
3414 Remove `cond' argument, now redundant.
3415 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)

3423 * print.c (strout): Remove parameter `multibyte', unused since
3424 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
3426 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
3427 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
3428 All callers changed.
3430 * w32.c (_wsa_errlist): Use braces for struct initializers.
3432 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
3433 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
3434 All callers changed.
3435 (string_buffer_position): Likewise. Also, make static (it's never
3436 used outside xdisp.c).
3437 (cursor_row_p): Remove parameter `w', unused since
3438 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
3439 (decode_mode_spec): Remove parameter `precision', introduced during
3440 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
3441 All callers changed.

3460 * nsmenu.m (runDialogAt): Remove argument to timer_check.
3462 2011-03-27 Glenn Morris <rgm@gnu.org>
3464 * syssignal.h: Replace RETSIGTYPE with void.
3465 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
3466 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
3467 Replace SIGTYPE with void everywhere.
3468 * s/usg5-4-common.h (SIGTYPE): Remove definition.

3474 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
3476 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
3478 * w32.c (read_unc_volume): Use parameter `henum', instead of
3479 global variable `wget_enum_handle'.

3504 (gap_left, gap_right): Don't call it.
3506 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
3508 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
3509 incurred during fontification.
3511 2011-03-25 Juanma Barranquero <lekktu@gmail.com>

3577 2011-03-23 Julien Danjou <julien@danjou.info>
3579 * term.c (Fsuspend_tty, Fresume_tty):
3580 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
3581 * window.c (temp_output_buffer_show):
3582 * insdel.c (signal_before_change):

3589 * buffer.c (Fkill_all_local_variables):
3590 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
3592 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
3593 unconditionnaly since it does the check itself.
3595 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
3597 Fix more problems found by GCC 4.5.2's static checks.
3599 * coding.c (encode_coding_raw_text): Avoid unnecessary test
3600 the first time through the loop, since we know p0 < p1 then.
3601 This also avoids a gcc -Wstrict-overflow warning.
3603 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
3604 leading to a memory leak, possible in functions like
3605 load_charset_map_from_file that can allocate an unbounded number
3606 of objects (Bug#8318).
3608 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
3609 that could (at least in theory) be that large.
3611 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
3612 This is less likely to overflow, and avoids undefined behavior if
3613 overflow does occur. All callers changed. Use strtoul to scan
3614 for the unsigned long integer.
3615 (pint2hrstr): Simplify and tune code slightly.
3616 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
3618 * scroll.c (do_scrolling): Work around GCC bug 48228.
3619 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

3622 This also avoids a warning with gcc -Wstrict-overflow.
3623 (validate_x_resource_name): Simplify count usage.
3624 This also avoids a warning with gcc -Wstrict-overflow.
3626 * fileio.c (Fcopy_file): Report error if fchown or fchmod
3629 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
3631 * process.c (Fmake_network_process): Use socklen_t, not int,
3632 where POSIX says socklen_t is required in portable programs.
3633 This fixes a porting bug on hosts like 64-bit HP-UX, where
3634 socklen_t is wider than int (Bug#8277).
3635 (Fmake_network_process, server_accept_connection):
3636 (wait_reading_process_output, read_process_output):
3639 * process.c: Rename or move locals to avoid shadowing.

3641 (read_process_output_error_handler, exec_sentinel_error_handler):
3642 Rename or move locals.
3643 (Fmake_network_process): Define label "retry_connect" only if needed.

3649 Make tparam.h and terminfo.c consistent.
3650 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
3651 Include tparam.h instead, since it declares them.
3652 * cm.h (PC): Remove extern decl; tparam.h now does this.
3653 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
3654 * terminfo.c: Include tparam.h, to check interfaces.
3655 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
3656 (tparam): Adjust signature to match interface in tparam.h;
3657 this removes some undefined behavior. Check that outstring and len
3658 are zero, which they always are with Emacs.
3659 * tparam.h (PC, BC, UP): New extern decls.
3661 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
3662 (xftfont_open): Rename locals to avoid shadowing.
3664 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
3665 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
3666 (OTF_TAG_SYM): Omit macro if not needed.
3667 (ftfont_list): Remove unused local.
3668 (get_adstyle_property, ftfont_pattern_entity):
3669 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
3670 Rename locals to avoid shadowing.
3672 * xfont.c (xfont_list_family): Mark var as initialized.
3674 * xml.c (make_dom): Now static.
3676 * composite.c (composition_compute_stop_pos): Rename local to
3678 (composition_reseat_it): Remove unused locals.
3679 (find_automatic_composition, composition_adjust_point): Likewise.
3680 (composition_update_it): Mark var as initialized.
3681 (find_automatic_composition): Mark vars as initialized,
3682 with a FIXME (Bug#8290).
3684 character.h: Rename locals to avoid shadowing.
3685 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
3686 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
3687 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
3688 (BUF_DEC_POS): Be more systematic about renaming local temporaries
3691 * textprop.c (property_change_between_p): Remove; unused.
3693 * intervals.c (interval_start_pos): Now static.
3695 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
3697 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
3698 Rename locals to avoid shadowing.
3700 * sound.c (wav_play, au_play, Fplay_sound_internal):
3701 Fix pointer signedness.
3702 (alsa_choose_format): Remove unused local var.
3703 (wav_play): Initialize a variable to 0, to prevent undefined
3704 behavior (Bug#8278).
3706 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
3708 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
3710 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
3711 clobbering (Bug#8298).
3712 * sysdep.c (sys_subshell): Likewise.
3713 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
3715 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
3716 This should get cleaned up, so that child_setup has the
3717 same signature on all platforms.
3719 * callproc.c (call_process_cleanup): Now static.
3720 (relocate_fd): Rename locals to avoid shadowing.
3722 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

3889 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3890 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
3891 to use the following functions instead of these macros.
3892 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
3893 EMACS_INT, since callers assume the returned value fits in int.
3894 (upcase1): Likewise, for UPCASE_TABLE.
3895 (uppercasep, lowercasep, upcase): New static inline functions.
3896 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

3906 (regex_compile, re_match_2_internal): Mark locals as initialized.
3907 (RETALLOC_IF): Define only if needed.
3908 (WORDCHAR_P): Likewise. This one is never needed, but is used
3909 only in a comment talking about a compiler bug, so put inside
3910 the #if 0 of that comment.
3911 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
3912 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
3915 * search.c (boyer_moore): Rename locals to avoid shadowing.

3938 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
3939 New macros, so that the caller can use some names other than
3940 gcpro1, gcpro2, etc.
3941 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
3943 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
3944 argument, for consistency with GCPRO2_VAR, etc: it is now the
3945 prefix of the variable, not the variable itself. All uses
3947 * dired.c (directory_files_internal, file_name_completion):
3948 Rename locals to avoid shadowing.
3950 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
3951 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
3952 dired.c's scmp function, had undefined behavior.
3953 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3954 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
3955 * buffer.h: ... to here, because these macros use current_buffer,
3956 and the new implementation with inline functions needs to have
3957 current_buffer in scope now, rather than later when the macros
3959 (downcase, upcase1): New static inline functions.
3960 (DOWNCASE, UPCASE1): Reimplement using these functions.
3961 This avoids undefined behavior in expressions like
3962 DOWNCASE (x) == DOWNCASE (y), which previously suffered
3963 from race conditions in accessing the global variables
3964 case_temp1 and case_temp2.
3965 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
3966 * lisp.h (case_temp1, case_temp2): Remove their decls.
3967 * character.h (ASCII_CHAR_P): Move from here ...
3968 * lisp.h: ... to here, so that the inline functions mentioned
3971 * dired.c (directory_files_internal_unwind): Now static.
3973 * fileio.c (file_name_as_directory, directory_file_name):
3974 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
3976 (file_name_as_directory): Use const pointers when appropriate.
3977 (Fexpand_file_name): Likewise. In particular, newdir might
3978 point at constant storage, so make it a const pointer.
3979 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
3980 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
3982 (Fset_file_times, Finsert_file_contents, auto_save_error):
3983 Rename locals to avoid shadowing.

3989 * marker.c (bytepos_to_charpos): Remove; unused.
3991 * lisp.h (verify_bytepos, count_markers): New decls,
3992 so that gcc does not warn that these functions aren't declared.
3994 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
3995 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
3996 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
3997 (copy_text): Remove unused local var.
3999 * filelock.c (within_one_second): Now static.
4000 (lock_file_1): Rename local to avoid shadowing.
4002 * buffer.c (fix_overlays_before): Mark locals as initialized.
4003 (fix_start_end_in_overlays): Likewise. This function should be
4004 simplified by using pointers-to-pointers, but that's a different
4006 (switch_to_buffer_1): Now static.
4007 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
4008 (report_overlay_modification): Rename locals to avoid shadowing.
4010 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
4011 Fix pointer signedness issue.
4012 (sys_subshell): Mark local as volatile if checking for lint,
4013 to suppress a gcc -Wclobbered warning that does not seem to be right.
4014 (MAXPATHLEN): Define only if needed.
4016 * process.c (serial_open, serial_configure): Move decls from here ...
4017 * systty.h: ... to here, so that they can be checked.
4019 * fns.c (get_random, seed_random): Move extern decls from here ...
4020 * lisp.h: ... to here, so that they can be checked.
4022 * sysdep.c (reset_io): Now static.
4023 (wait_for_termination_signal): Remove; unused.
4025 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
4026 (copy_keymap_item, append_key, push_text_char_description):
4028 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
4029 (DENSE_TABLE_SIZE): Remove; unused.

4031 (describe_map_tree):
4032 Rename locals to avoid shadowing.
4034 * keyboard.c: Declare functions static if they are not used elsewhere.
4035 (echo_char, echo_dash, cmd_error, top_level_2):
4036 (poll_for_input, handle_async_input): Now static.
4037 (read_char, kbd_buffer_get_event, make_lispy_position):
4038 (make_lispy_event, make_lispy_movement, apply_modifiers):
4039 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

4056 if GCC considers string literals to be constants.
4058 * lisp.h (fatal_error_signal): Add decl, since it's exported.
4060 * dbusbind.c: Pointer signedness fixes.
4061 (xd_signature, xd_append_arg, xd_initialize):

4182 1152921504606846976) returns the obviously-bogus value (-948597
4183 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
4184 reports time overflow. See
4185 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
