[bpt/emacs.git] / src / ChangeLog
1 2012-04-01 Eli Zaretskii <eliz@gnu.org>
2
3 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4 instead of alloca. (Bug#11138)
5
6 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
7
8 * w32menu.c (is_simple_dialog): Properly check lisp types.
9 (Bug#11141)
10
11 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12
13 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14 position we get to after a call to move_it_to fails the
15 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
16 only if we wind up in a string from display property. (Bug#11063)
17
18 * window.c (Fdelete_other_windows_internal): Invalidate the row
19 and column information about mouse highlight, so that redisplay
20 restores it after reallocating the glyph matrices. (Bug#7464)
21
22 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
23 string comes from a `display' text property, use the buffer
24 position of that property as if we actually saw that position in
25 the row's glyphs.
26 (move_it_by_lines): Remove the assertion that
27 "it->current_x == 0 && it->hpos == 0" which can be legitimately
28 violated when there's a before-string at the beginning of a line.
29 (Bug#11063)
30
31 2012-03-30 Eli Zaretskii <eliz@gnu.org>
32
33 * xdisp.c (append_space_for_newline): If the default face was
34 remapped, use the remapped face for the appended newline.
35 (extend_face_to_end_of_line): Use the remapped default face for
36 extending the face to the end of the line.
37 (display_line): Call extend_face_to_end_of_line when the default
38 face was remapped. (Bug#11068)
39
40 2012-03-29 Eli Zaretskii <eliz@gnu.org>
41
42 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
43
44 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
45
46 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
47
48 2012-03-27 Glenn Morris <rgm@gnu.org>
49
50 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
51 Doc fixes.
52
53 2012-03-26 Kenichi Handa <handa@m17n.org>
54
55 * dispextern.h (struct glyph): Fix previous change. Change the
56 bit length of glyphless.ch to 25 (Bug#11082).
57
58 2012-03-26 Chong Yidong <cyd@gnu.org>
59
60 * keyboard.c (Vselection_inhibit_update_commands): New variable.
61 (command_loop_1): Use it; inhibit selection update for
62 handle-select-window too (Bug#8996).
63
64 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
65

67
68 2012-03-25 Kenichi Handa <handa@m17n.org>
69
70 * dispextern.h (struct glyph): Change the bit length of
71 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
72
73 2012-03-24 Eli Zaretskii <eliz@gnu.org>
74
75 * s/ms-w32.h (tzname): Include time.h before redirecting to
76 _tzname. Fixes the MSVC build. (Bug#9960)
77
78 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
79
80 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
81 characters.
82
83 * xterm.c (XTread_socket): Only modify handling_signal if
84 !SYNC_INPUT. (Bug#11080)
85
86 2012-03-23 Eli Zaretskii <eliz@gnu.org>
87
88 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
89 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
90 when fetching a multibyte character consumes more bytes than
91 CHAR_BYTES returns, due to unification of CJK characters in
92 string_char. (Bug#11073)
93
94 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
95
96 * process.c (wait_reading_process_output): Handle pty disconnect

102
103 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
104 Mark string as coming from a prefix property.
105 (handle_face_prop): Use default face for prefix strings (Bug#4281).
106 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
107
108 2012-03-21 Chong Yidong <cyd@gnu.org>
109
110 * xfaces.c (Vface_remapping_alist): Doc fix.
111
112 2012-03-20 Eli Zaretskii <eliz@gnu.org>
113
114 * w32proc.c (Fw32_set_console_codepage)

117
118 2012-03-20 Chong Yidong <cyd@gnu.org>
119
120 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
121 to reflect default non-nil value of redisplay-dont-pause.
122
123 2012-03-19 Kenichi Handa <handa@m17n.org>
124
125 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
126 it fit in a valid range (Bug#11003).
127
128 2012-03-18 Eli Zaretskii <eliz@gnu.org>
129
130 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
131 that is not from display property, accept the row as a "cursor
132 row" if one of the string's character has a non-nil `cursor'
133 property. Fixes cursor positioning when there are newlines in
134 overlay strings, e.g. in icomplete.el. (Bug#11035)
135
136 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
137
138 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
139
140 2012-03-12 Chong Yidong <cyd@gnu.org>
141
142 * eval.c (inhibit_lisp_code): Rename from
143 inhibit_window_configuration_change_hook; move from window.c.
144
145 * xfns.c (unwind_create_frame_1, Fx_create_frame):
146 * window.c (run_window_configuration_change_hook)
147 (syms_of_window): Callers changed.

163
164 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
165
166 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
167 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
168 zero (Bug#10954).
169
170 2012-03-03 Glenn Morris <rgm@gnu.org>
171
172 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

175
176 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
177 position past the first glyph_row that ends at ZV. (Bug#10902)
178 (redisplay_window, next_element_from_string): Fix typos in
179 comments.
180 (redisplay_window): Pass to move_it_vertically the margin in
181 pixels, not in screen lines.
182
183 2012-03-02 Glenn Morris <rgm@gnu.org>
184
185 * buffer.c (buffer-list-update-hook): Doc fix.
186
187 2012-02-29 Eli Zaretskii <eliz@gnu.org>
188

190 push_it before setting up the iterator for the first overlay
191 string, even if we have an empty string loaded.
192 (next_overlay_string): If there's an empty string on the iterator
193 stack, pop the stack. (Bug#10903)

196
197 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
198 Suggested by Stefan Monnier in
199 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
200 * alloc.c (widen_to_Lisp_Object): New static function.
201 (mark_memory): Also mark Lisp_Objects by fetching pointer words
202 and widening them to Lisp_Objects. This would work even if
203 USE_LSB_TAG is defined and wide integers are used, which might
204 happen in a future version of Emacs.
205
206 2012-02-25 Chong Yidong <cyd@gnu.org>
207
208 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
209 Doc fix.
210
211 * xselect.c (Fx_selection_exists_p): Doc fix.
212 (x_clipboard_manager_save_all): Print an informative message
213 before saving to clipboard manager.
214
215 2012-02-24 Chong Yidong <cyd@gnu.org>
216
217 * keyboard.c (process_special_events): Handle all X selection
218 requests in kbd_buffer, not just the next one (Bug#8869).
219
220 2012-02-23 Chong Yidong <cyd@gnu.org>
221
222 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
223 call when setting menu-bar-lines and tool-bar-lines parameters.
224 (unwind_create_frame_1): New helper function.
225
226 * window.c (inhibit_window_configuration_change_hook): New var.
227 (run_window_configuration_change_hook): Obey it.
228 (syms_of_window): Initialize it.
229
230 2012-02-22 Chong Yidong <cyd@gnu.org>
231
232 * xterm.c (x_draw_image_relief): Add missing type check for
233 Vtool_bar_button_margin (Bug#10743).
234
235 2012-02-21 Chong Yidong <cyd@gnu.org>
236
237 * fileio.c (Vfile_name_handler_alist): Doc fix.
238
239 * buffer.c (Fget_file_buffer): Protect against invalid file

245 when computing $valmask.
246
247 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
248 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
249 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
250 It's useless in that case, and it can cause problems on hosts
251 that allocate halves of EMACS_INT values separately.
252 Reported by Dan Horák. Diagnosed by Andreas Schwab in
253 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
254 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
255 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
256 it avoids undefined behavior on hosts where shifting right by more
257 than the word width has undefined behavior.
258
259 2012-02-19 Chong Yidong <cyd@gnu.org>
260
261 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
262 (Funhandled_file_name_directory, Ffile_name_as_directory)
263 (Fdirectory_file_name, Fexpand_file_name)
264 (Fsubstitute_in_file_name): Protect against invalid file handler
265 return values (Bug#10845).
266
267 2012-02-18 Eli Zaretskii <eliz@gnu.org>
268
269 * .gdbinit (pitx): Fix incorrect references to fields of the
270 iterator stack.
271
272 2012-02-17 Chong Yidong <cyd@gnu.org>
273
274 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
275
276 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
277
278 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
279 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
280
281 2012-02-15 Chong Yidong <cyd@gnu.org>
282
283 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
284 marked as special. Also, starting docstrings with * is obsolete.
285

287
288 * gnutls.c (emacs_gnutls_write): Fix last change.

298
299 2012-02-12 Chong Yidong <cyd@gnu.org>
300
301 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
302 as that creates a dangerous corner case.
303
304 * window.c (Fdelete_window_internal): Invalidate the mouse
305 highlight (Bug#9904).
306
307 2012-02-12 Glenn Morris <rgm@gnu.org>
308
309 * xselect.c (Fx_own_selection_internal)
310 (Fx_get_selection_internal, Fx_disown_selection_internal)

312 * nsselect.m (Fx_own_selection_internal)
313 (Fx_disown_selection_internal, Fx_selection_exists_p)
314 (Fx_selection_owner_p, Fx_get_selection_internal):
315 Sync docs and argument specs with the xselect.c versions.

325
326 * w16select.c (Fx_selection_exists_p): Sync doc string and
327 argument list with xselect.c. (Bug#10783)

332
333 2012-02-09 Kenichi Handa <handa@m17n.org>
334
335 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).

338
339 * buffer.c (Fbuffer_local_variables)
340 (buffer_lisp_local_variables): Handle unbound vars correctly;

351 2012-02-06 Chong Yidong <cyd@gnu.org>
352
353 * doc.c (store_function_docstring): Avoid applying docstring of
354 alias to base function (Bug#2603).

364
365 2012-02-04 Eli Zaretskii <eliz@gnu.org>
366
367 * w32.c (get_emacs_configuration_options):
368 Include --enable-checking, if specified, in the return value.
369
370 2012-02-04 Martin Rudalics <rudalics@gmx.at>
371
372 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
373 after rounding frame sizes. (Bug#9723)

379
380 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
381
382 Handle overflow when computing char display width (Bug#9496).
383 * character.c (char_width): Return EMACS_INT, not int.
384 (char_width, c_string_width): Check for overflow when
385 computing the width; this is possible now that individual
386 characters can have unbounded width. Problem introduced
387 by merge from Emacs 23 on 2012-01-19.
388
389 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
390

392 :ignore in the docstring.
393
394 2012-02-02 Glenn Morris <rgm@gnu.org>
395
396 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
397
398 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

407 0, do not call append_composite_glyph.
408
409 2012-02-02 Kenichi Handa <handa@m17n.org>
410
411 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
412 NULL (Bug#6988).
413 (x_produce_glyphs): If the component of a composition is a null
414 string, set it->pixel_width to 1 to avoid zero-width glyph.
415
416 2012-02-01 Eli Zaretskii <eliz@gnu.org>
417
418 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
419 first 2 arguments are identical. This makes inserting large
420 output from a subprocess an order of magnitude faster on
421 MS-Windows, where all sbrk'ed memory is always contiguous.
422
423 2012-01-31 Glenn Morris <rgm@gnu.org>
424

1036 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
1037 Otherwise, valgrind does not work on some platforms.
1038 Problem reported by Andreas Schwab in
1039 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
1040 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
1041 is set, removing the need for VIRT_ADDRESS_VARIES.
1042 (PURE_P): Use a more-efficient implementation that needs just one
1043 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
1044 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
1045 to 4 (xorl, subq, cmpq, setbe).
1046 * alloc.c (pure): Always extern now, since that's the
1047 VIRT_ADDR_VARIES behavior.
1048 (PURE_POINTER_P): Use a single comparison, not two, for
1049 consistency with the new puresize.h.
1050 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
1051 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
1052 Remove VIRT_ADDR_VARIES no longer needed.

1056 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
1057 (erase_phys_cursor, update_window_cursor, show_mouse_face)
1058 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
1059 behave as if the cursor position were at the window margin.
1060
1061 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
1062 and the cursor position is out of bounds, behave as if the cursor
1063 position were at the window margin. (Bug#10075)
1064
1065 2011-11-18 Chong Yidong <cyd@gnu.org>
1066
1067 * window.c (Fwindow_combination_limit): Make first argument
1068 non-optional, since it is meaningless for live windows like the
1069 selected window.
1070
1071 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>
1072
1073 * keymap.c (Fwhere_is_internal): Add missing RETURN_UNGCPROs.

1083 hash values of the two rows.
1084 (copy_row_except_pointers): Preserve the used[] arrays and the
1085 hash values of the two rows. (Bug#10035)
1086 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
1087
1088 * xdisp.c (row_hash): New function, body extracted from
1089 compute_line_metrics.
1090 (compute_line_metrics): Call row_hash, instead of computing the
1091 hash code inline.
1092
1093 * dispnew.c (verify_row_hash): Call row_hash for computing the
1094 hash code of a row, instead of duplicating code from xdisp.c.
1095
1096 * dispextern.h (row_hash): Add prototype.
1097
1098 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

1132 * image.c (imagemagick_load_image): Fix typo.
1133
1134 2011-11-14 Eli Zaretskii <eliz@gnu.org>
1135
1136 * xdisp.c (display_line): Move the call to
1137 highlight_trailing_whitespace before the call to
1138 compute_line_metrics, since the latter needs to see the final
1139 faces of all the glyphs to compute ROW's hash value.
1140 Fixes assertion violations in row_equal_p. (Bug#10035)
1141
1142 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
1143
1144 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
1145 just return (bug#10044).
1146
1147 2011-11-12 Eli Zaretskii <eliz@gnu.org>
1148
1149 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
1150 with user-defined heap size. Bump the default size of the temacs
1151 heap to 27MB, to avoid memory warning when running temacs.
1152 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
1153
1154 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
1155 current_matrix and desired_matrix. (Bug#9990)
1156 (verify_row_hash) [XASSERTS]: New function.
1157 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
1158 that the hash value of glyph rows is correct.

1186
1187 2011-11-11 Johan Bockgård <bojohan@gnu.org>
1188
1189 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
1190 avoid a crash (bug#9496).
1191
1192 2011-11-09 Chong Yidong <cyd@gnu.org>
1193
1194 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

1202
1203 Avoid some portability problems by eschewing 'extern inline' functions.
1204 The trivial performance wins aren't worth the portability hassles; see
1205 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
1206 et seq.
1207 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

1235
1236 * w32.c (check_windows_init_file): Don't look for term/w32-win.el

1238 of temacs in GUI mode.
1239
1240 2011-11-07 Martin Rudalics <rudalics@gmx.at>
1241

1252
1253 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
1254
1255 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
1256 This is also needed for porting to any host where GC_MARK_STACK is
1257 not GC_MAKE_GCPROS_NOOPS.
1258 (which_symbols): Use it.
1259
1260 2011-11-07 Kenichi Handa <handa@m17n.org>
1261
1262 * coding.c (coding_set_destination): Check coding->src_pos only
1263 when coding->src_object is a buffer (bug#9910).
1264
1265 * process.c (send_process): Set the member src_multibyte of coding
1266 to 0 (bug#9911) when sending a unibyte text.
1267

1272
1273 * xmenu.c (cleanup_widget_value_tree): New function.
1274 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
1275 calling free_menubar_widget_value_tree directly (Bug#9830).
1276
1277 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
1278

1280 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
1281 (window_box_width, window_box_left, window_box_left_offset)
1282 (window_box_right, window_box_right_offset): Declare extern.
1283 Otherwise, these inline functions do not conform to C99 and
1284 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
1285 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
1286 * intervals.c (adjust_intervals_for_insertion)
1287 (adjust_intervals_for_deletion): Now extern, because otherwise the
1288 extern inline functions 'offset_intervals' couldn't refer to it.
1289 (static_offset_intervals): Remove.
1290 (offset_intervals): Rewrite using the old contents of
1291 static_offset_intervals. The old version didn't conform to C99
1292 because an extern inline function contained a reference to an
1293 identifier with static linkage.
1294
1295 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
1296
1297 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

1301
1302 * xdisp.c (init_iterator, reseat_to_string): Don't set the
1303 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)

1313 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
1314 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
1315 (Fwindow_vscroll): Doc fix.
1316 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
1317 argument, since it makes no sense to pass a live window and for
1318 consistency with window-child.
1319
1320 2011-11-05 Christoph Scholtes <cschol2112@googlemail.com>
1321
1322 * makefile.w32-in ($(TEMACS), (gl-stamp)): Use $(THISDIR) to

1548 non-NULL, regardless of GNUTLS_INITSTAGE.
1549 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
1550 an error. Set process slots as soon as we allocate them.
1551
1552 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.

1596 current character, check also for next_en_type being WEAK_EN.
1597 (bidi_resolve_weak): Don't enter the expensive loop if the current
1598 position is before next_en_pos. Record the bidi type of the first
1599 non-ET, non-BN character we find, in addition to its position.
1600 (bidi_level_of_next_char): Invalidate next_en_type when
1601 next_en_pos is over-stepped.

1604
1605 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
1606 * editfns.c: Rewrite current-time-zone so that it invokes
1607 the equivalent of (format-time-string "%Z") to get the time zone name.
1608 This fixes a bug when the time zone name contains characters that
1609 need converting from the system time locale to Emacs internal format.
1610 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
1611 that patch fixed format-time-string to do the conversion, but
1612 I forgot to fix current-time-zone.
1613 (format_time_string): New function, containing most of
1614 what Fformat_time_string used to contain.
1615 (Fformat_time_string): Rewrite in terms of format_time_string.
1616 This doesn't change this function's behavior.
1617 (current-time-zone): Rewrite to use format_time_string.
1618 This fixes the bug reported by Michael Schierl in
1619 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
1620 Jason Rumney's 2007-06-07 change worked around this bug, but
1621 didn't fix it.
1622 * systime.h (tzname, timezone): Remove no-longer-used declarations.
1623
1624 2011-10-19 Eli Zaretskii <eliz@gnu.org>
1625
1626 * xdisp.c (start_display): If the character at POS is displayed
1627 via a display vector, reset IT->current.dpvec_index to zero.
1628 (try_window_reusing_current_matrix): If a line ends in a display
1629 vector or the next line starts in a display vector, continue
1630 redrawing the window even though the character position of
1631 start_row was reached.
1632 (Bug#9771, part 2)
1633
1634 2011-10-18 Chong Yidong <cyd@gnu.org>

1639 2011-10-18 Eli Zaretskii <eliz@gnu.org>
1640
1641 Fix part 3 of bug#9771.
1642 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
1643 (bidi_resolve_neutral): Don't enter the expensive loop looking for
1644 non-neutral characters if the current character is a paragraph
1645 separator (a.k.a. Newline). This avoids running the same
1646 expensive loop twice, once when we consume the preceding newline
1647 and the other time when the line actually needs to be displayed.
1648 Avoid the loop when we see neutrals on the base embedding level
1649 following a character whose directionality is the same as the
1650 paragraph's. This avoids running the expensive loop when a line
1651 ends in a long sequence of neutrals, like control characters.
1652 Add assertion against STRONG_AL type. Slightly rearrange code
1653 that determines the type of a neutral given the first non-neutral
1654 that follows it.
1655 (bidi_level_of_next_char): Set next_en_pos to zero when
1656 invalidating its info.
1657
1658 2011-10-17 Eli Zaretskii <eliz@gnu.org>
1659
1660 * xdisp.c (push_display_prop): Determine whether to record string
1661 or buffer position by IT->string, not by IT->method. Allow
1662 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
1663 (move_it_vertically_backward): Don't look for character position
1664 immediately after the newline when in a continuation line.
1665 (Bug#9771, part 1)
1666
1667 2011-10-15 Martin Rudalics <rudalics@gmx.at>

1683
1684 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
1685 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
1686 cursor motion with <left> and <right> arrow keys.
1687
1688 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
1689 some callers set that themselves.
1690
1691 2011-10-12 Eli Zaretskii <eliz@gnu.org>
1692
1693 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
1694 display string and the previous row comes from the same string and
1695 is empty. (Bug#9739) (Bug#9738)
1696
1697 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

1740 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
1741 lines.
1742 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
1743 lines that are hscrolled on the left.
1744
1745 * dispnew.c (buffer_posn_from_coords): Account for a possible
1746 presence of header-line. (Bug#4426)
1747
1748 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
1749
1750 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
1751 Don't advertise functionality which we discourage or doesn't work.
1752
1753 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
1754
1755 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
1756 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
1757 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
1758 this makes Emacs dump core during garbage collection on rare
1759 occasions. sizeof is obviously inferior to offsetof here, so
1760 stick with offsetof.
1761 (GC_POINTER_ALIGNMENT): New macro.
1762 (mark_memory): Omit 3rd (offset) arg; caller changed.
1763 Don't assume EMACS_INT alignment is the same as pointer alignment.
1764
1765 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
1766
1767 * keyboard.c (read_key_sequence_remapped): New var.
1768 (read_key_sequence): Compute remapping in the right buffer.
1769 (command_loop_1): Use read_key_sequence's remapping directly.
1770
1771 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1772
1773 * dired.c (file_name_completion): Don't expand file name.
1774 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
1775 before checking file name handler.
1776
1777 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
1778 they've been requested explicitly (bug#9591).
1779
1780 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
1781
1782 * keymap.c (Fsingle_key_description): Use make_specified_string
1783 instead of build_string to build string from push_key_description.
1784 (Bug#5193)
1785
1786 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1787
1788 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
1789 This fixes a Y2038 bug on 64-bit hosts.
1790 * buffer.c (reset_buffer):
1791 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
1792 (Fclear_buffer_auto_save_failure):
1793 Use 0, not -1, to represent an unset failure time, since time_t
1794 might not be signed.
1795
1796 Remove dependency on glibc malloc internals.
1797 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1798 Move back here from lisp.h, but with their new implementations.
1799 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1800 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
1801 * charset.c (charset_table_init): New static var.
1802 (syms_of_charset): Use it instead of xmalloc. This removes a
1803 dependency on glibc malloc internals. See Eli Zaretskii's comment in
1804 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
1805 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1806 Move back to alloc.c.
1807 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1808 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
1809
1810 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
1811
1812 * nsterm.m (windowDidResize): Call x_set_window_size only when
1813 ns_in_resize is true. Otherwise set pixelwidth/height and
1814 call change_frame_size (Bug#9628).
1815
1816 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1817
1818 Port --enable-checking=all to Fedora 14 x86-64.
1819 * charset.c (syms_of_charset): Also account for glibc malloc's
1820 internal overhead when calculating the initial malloc maximum.
1821
1822 Port --enable-checking=all to Fedora 14 x86.
1823 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1824 Move to lisp.h.
1825 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
1826 (overrun_check_realloc, overrun_check_free):
1827 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
1828 That way, xmalloc returns a properly-aligned pointer even if
1829 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
1830 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
1831 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
1832 into account when calculating the initial malloc maximum.
1833 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1834 Move here from alloc.c, so that charset.c can use it too.
1835 Properly align; the old code wasn't right for common 32-bit hosts
1836 when configured with --enable-checking=all.
1837 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1838 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
1839
1840 2011-09-29 Eli Zaretskii <eliz@gnu.org>
1841
1842 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
1843 use EDOM.
1844
1845 2011-09-28 Eli Zaretskii <eliz@gnu.org>
1846
1847 * xdisp.c (compute_display_string_end): If there's no display
1848 string at CHARPOS, return -1.
1849
1850 * bidi.c (bidi_fetch_char): When compute_display_string_end
1851 returns a negative value, treat the character as a normal
1852 character not covered by a display string. (Bug#9624)
1853
1854 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
1855
1856 * lread.c (Fread_from_string): Fix typo in docstring.
1857
1858 2011-09-27 Eli Zaretskii <eliz@gnu.org>
1859
1860 * xdisp.c (handle_invisible_prop): If invisible text ends on a
1861 newline, reseat the iterator instead of bidi-iterating there one
1862 character at a time. (Bug#9610)
1863 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
1864 TO_CHARPOS if the bidi iterator is at base embedding level.
1865
1866 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
1867
1868 * lread.c (readevalloop): Use correct code for NBSP.
1869 (read1): Likewise. (Bug#9608)
1870
1871 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
1872
1873 * dbusbind.c (Fdbus_register_signal): When service is not
1874 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
1875
1876 2011-09-25 Glenn Morris <rgm@gnu.org>
1877
1878 * buffer.c (truncate-lines): Doc fix.
1879
1880 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
1881
1882 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
1883 (Fset_window_next_buffers): Doc fix.
1884
1885 2011-09-24 Glenn Morris <rgm@gnu.org>
1886
1887 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
1888
1889 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
1890
1891 Fix minor problems found by static checking.
1892 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
1893 * indent.c (Fvertical_motion): Fix == vs = typo.
1894
1895 2011-09-24 Eli Zaretskii <eliz@gnu.org>
1896
1897 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
1898 Default value is now t. Doc fix.
1899
1900 * indent.c (Fvertical_motion): Compute and apply the overshoot
1901 logic when moving up, not only when moving down. Fix the
1902 confusing name and values of the it_overshoot_expected variable;
1903 logic changes accordingly. (Bug#9254) (Bug#9549)
1904
1905 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
1906 CHARPOS is covered by a display string which includes newlines.
1907 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
1908 is covered by a display string with embedded newlines.
1909
1910 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
1911
1912 * dbusbind.c (Fdbus_register_signal): Add match rule to
1913 Vdbus_registered_objects_table. (Bug#9581)
1914 (Fdbus_register_method, Vdbus_registered_objects_table):
1915 Fix docstring.
1916
1917 2011-09-24 Jim Meyering <meyering@redhat.com>
1918
1919 do not ignore write error for any output size
1920 The previous change was incomplete.
1921 While it makes emacs --batch detect the vast majority of stdout
1922 write failures, errors were still ignored whenever the output size is
1923 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
1924 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
1925 && echo FAIL: ignored write error
1926 FAIL: ignored write error
1927 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
1928 && echo FAIL: ignored write error
1929 FAIL: ignored write error
1930 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
1931
1932 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
1933
1934 * emacs.c (Fkill_emacs): In noninteractive mode exit
1935 non-successfully if a write error occurred on stdout. (Bug#9574)
1936
1937 2011-09-21 Eli Zaretskii <eliz@gnu.org>
1938
1939 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
1940 the xassert test.
1941
1942 * dispextern.h (struct it): Update the comment documenting what
1943 can it->OBJECT be.
1944
1945 2011-09-20 Eli Zaretskii <eliz@gnu.org>
1946
1947 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
1948 a display string, extend search for cursor position to end of row.
1949 (find_row_edges): If the row ends in a newline from a display
1950 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
1951 Handle the case of a display string with multiple newlines.
1952 (Fcurrent_bidi_paragraph_direction): Fix search for previous
1953 non-empty line. Fixes confusing cursor motion with arrow keys at
1954 the beginning of a line that starts with whitespace.
1955
1956 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1957
1958 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
1959 (bug#9493).
1960
1961 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
1962
1963 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
1964 boolean (Bug#9154).
1965
1966 2011-09-18 Eli Zaretskii <eliz@gnu.org>
1967
1968 * xdisp.c (display_line): Record maximum and minimum buffer
1969 positions even if no glyphs were produced (e.g., by a zero-width
1970 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
1971 buffer positions that will be removed from the glyph row because
1972 they don't fit.
1973 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
1974 column is beyond frame width: don't subtract 1 "pixel" when
1975 computing width of the stretch.
1976 (reseat_at_next_visible_line_start): Undo the change made on
1977 2011-09-17 that saved paragraph information and restored it after
1978 the call to `reseat'. (Bug#9545)
1979
1980 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1981
1982 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
1983 and turn window cursor on if cleared (Bug#9415).
1984
1985 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
1986
1987 * search.c (boyer_moore): Take unibyte characters from pattern
1988 literally. (Bug#9458)
1989
1990 2011-09-18 Eli Zaretskii <eliz@gnu.org>
1991
1992 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
1993
1994 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
1995
1996 Fix minor problem found by static checking.
1997 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
1998 initialized, to pacify gcc -Wuninitialized.
1999
2000 * fileio.c: Report proper errno when syscall falls.
2001 (Finsert_file_contents): Save and restore errno,
2002 so that report_file_error outputs the correct diagnostic.
2003 (Fwrite_region) [CLASH_DETECTION]: Likewise.
2004
2005 2011-09-18 Eli Zaretskii <eliz@gnu.org>
2006
2007 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
2008
2009 2011-09-17 Eli Zaretskii <eliz@gnu.org>
2010
2011 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
2012 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
2013
2014 2011-09-17 Eli Zaretskii <eliz@gnu.org>
2015
2016 * xdisp.c (reseat_at_next_visible_line_start): Keep information
2017 about the current paragraph and restore it after the call to reseat.
2018
2019 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
2020 (bidi_find_paragraph_start): Search back for paragraph beginning
2021 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
2022 (bidi_move_to_visually_next): Only trigger paragraph-related
2023 computations when the last character is a newline or at EOB, not
2024 just any NEUTRAL_B. (Bug#9470)
2025
2026 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
2027 truncated lines if point is covered by a display string. (Bug#9524)
2028
2029 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
2030
2031 * xselect.c: Relax test for outgoing X longs (Bug#9498).
2032 (cons_to_x_long): New function.
2033 (lisp_data_to_selection_data): Use it. Correct the test for
2034 short-versus-long data; it was negated. Break out of vector
2035 loop, for efficiency, when a long datum is discovered.
2036
2037 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
2038
2039 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
2040
2041 2011-09-16 Eli Zaretskii <eliz@gnu.org>
2042
2043 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
2044 GCC PR/17406) by declaring this function with external scope.
2045
2046 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
2047
2048 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
2049 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
2050
2051 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
2052
2053 * editfns.c (Fformat): Correctly handle text properties on "%%".
2054
2055 2011-09-15 Eli Zaretskii <eliz@gnu.org>
2056
2057 * xterm.c (x_draw_composite_glyph_string_foreground):
2058 * w32term.c (x_draw_composite_glyph_string_foreground):
2059 * term.c (encode_terminal_code):
2060 * composite.c (composition_update_it, get_composition_id):
2061 * xdisp.c (get_next_display_element)
2062 (fill_composite_glyph_string): Add comments about special meaning
2063 of TAB characters in a composition.
2064
2065 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
2066
2067 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
2068 This occurs when processing a multibyte format.
2069 Problem reported by Wolfgang Jenker.
2070
2071 2011-09-15 Johan Bockgård <bojohan@gnu.org>
2072
2073 * xdisp.c (try_cursor_movement): Only check for exact match if
2074 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
2075
2076 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
2077
2078 Remove unused external symbols.
2079 * dispextern.h (calc_pixel_width_or_height): Remove decl.
2080 * xdisp.c (calc_pixel_width_or_height): Now static.
2081 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

2083 * w32term.c: Fix comment to match code.
2084 * xterm.c, xterm.h (x_catching_errors): Remove.
2085
2086 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
2087
2088 * xselect.c: Use signed conversions more consistently (Bug#9498).
2089 (selection_data_to_lisp_data): Assume incoming selection data are
2090 signed integers, not unsigned. This is to be consistent with
2091 outgoing selection data, which was modified to use signed integers
2092 in as part of the fix to Bug#9196 in response to Jan D.'s comment
2093 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
2094 expects long, not unsigned long.
2095
2096 2011-09-14 Eli Zaretskii <eliz@gnu.org>
2097
2098 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
2099 computation of loop end. Reported by Johan Bockgård
2100 <bojohan@gnu.org>.
2101
2102 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
2103
2104 * frame.c (Fother_visible_frames_p): Function deleted.
2105
2106 2011-09-12 Eli Zaretskii <eliz@gnu.org>
2107
2108 * indent.c (compute_motion): Process display vector front to back
2109 rather than the other way around. (Bug#2496)
2110
2111 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2112
2113 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
2114
2115 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
2116
2117 * minibuf.c (Fread_from_minibuffer): Doc fix.
2118
2119 2011-09-11 Eli Zaretskii <eliz@gnu.org>
2120
2121 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
2122 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
2123
2124 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
2125
2126 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
2127 value for non-existent files.
2128
2129 2011-09-11 Eli Zaretskii <eliz@gnu.org>
2130
2131 * fileio.c (Finsert_file_contents): If the file cannot be opened,
2132 set its "size" to -1. This will set the modtime_size field of
2133 the corresponding buffer to -1, which is what
2134 verify-visited-file-modtime expects for files that do not exist.
2135 (Bug#9139)
2136
2137 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
2138
2139 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
2140 here ...
2141 * lisp.h: ... from here. push_key_description is no longer
2142 defined in keyboard.c, so its declaration should not be in
2143 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
2144 logically belongs with push_key_description.
2145
2146 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
2147
2148 * buffer.h: Include <sys/types.h> instead of <time.h>.
2149 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
2150 Problem reported by Herbert J. Skuhra.

2153
2154 * xml.c (parse_region): Make the parsing work for
2155 non-comment-starting XML files again (bug#9144).
2156
2157 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
2158
2159 * image.c (gif_load): Fix calculation of bottom and right corner.
2160 (Bug#9468)
2161
2162 2011-09-10 Eli Zaretskii <eliz@gnu.org>
2163
2164 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
2165 redisplay in small windows.
2166
2167 2011-09-09 Eli Zaretskii <eliz@gnu.org>
2168
2169 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
2170
2171 2011-09-08 Martin Rudalics <rudalics@gmx.at>
2172
2173 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
2174 Operate on live windows only.
2175
2176 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
2177
2178 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
2179
2180 2011-09-07 Eli Zaretskii <eliz@gnu.org>
2181
2182 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
2183 only under bidi iteration.
2184
2185 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
2186
2187 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
2188
2189 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2190
2191 isnan: Fix porting problem to Solaris 10 with bundled gcc.
2192 Without this fix, the command to link temacs failed due to an
2193 undefined symbol __builtin_isnan. This is because
2194 /usr/include/iso/math_c99.h #defines isnan(x) to
2195 __builtin_isnan(x), but the bundled gcc, which identifies itself
2196 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
2197 a __builtin_isnan.
2198 * floatfns.c (isnan): #undef, and then #define to a clone of
2199 what's in data.c.
2200 (Fisnan): Always define, since it's always available now.
2201 (syms_of_floatfns): Always define isnan at the Lisp level.
2202
2203 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2204
2205 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
2206
2207 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2208
2209 * fileio.c: Fix bugs with large file offsets (Bug#9428).
2210 The previous code assumed that file offsets (off_t values) fit in
2211 EMACS_INT variables, which is not true on typical 32-bit hosts.
2212 The code messed up by falsely reporting buffer overflow in cases
2213 such as (insert-file-contents "big" nil 1 2) into an empty buffer
2214 when "big" contains more than 2**29 bytes, even though this
2215 inserts just one byte and does not overflow the buffer.
2216 (Finsert_file_contents): Store file offsets as off_t
2217 values, not as EMACS_INT values. Check for overflow when
2218 converting between EMACS_INT and off_t. When checking for
2219 buffer overflow or for overlap, take the offsets into account.
2220 Don't use EMACS_INT for small values where int suffices.
2221 When checking for overlap, fix a typo: ZV was used where
2222 ZV_BYTE was intended.
2223 (Fwrite_region): Don't assume off_t fits into 'long'.
2224 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
2225
2226 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
2227
2228 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
2229
2230 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2231
2232 sprintf-related integer and memory overflow issues (Bug#9412).
2233
2234 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
2235 (esprintf, exprintf, evxprintf): New functions.
2236 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
2237 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
2238 (modify_event_symbol): Do not assume that the length of
2239 name_alist_or_stem is safe to alloca and fits in int.
2240 (Fexecute_extended_command): Likewise for function name and binding.
2241 (Frecursion_depth): Wrap around reliably on integer overflow.
2242 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
2243 since some callers pass EMACS_INT values.
2244 (Fsingle_key_description): Don't crash if symbol name contains more
2245 than MAX_ALLOCA bytes.
2246 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
2247 (get_minibuffer): Arg is now EMACS_INT, not int.
2248 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
2249 (esprintf, exprintf, evxprintf): New decls.
2250 * window.h (command_loop_level, minibuf_level): Reflect API changes.
2251
2252 * dbusbind.c (signature_cat): New function.
2253 (xd_signature, Fdbus_register_signal):
2254 Do not overrun buffer; instead, report string overflow.
2255
2256 * dispnew.c (add_window_display_history): Don't overrun buffer.
2257 Truncate instead; this is OK since it's just a log.
2258
2259 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
2260 even if the time zone offset is outlandishly large.
2261 Don't mishandle offset == INT_MIN.
2262
2263 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
2264 when creating daemon; the previous buffer-overflow check was incorrect.
2265
2266 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
2267 which has the guts of the old verror function.
2268
2269 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
2270 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
2271
2272 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
2273 (font_unparse_xlfd): Don't blindly alloca long strings.
2274 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
2275 fits in int, when using sprintf. Use single snprintf to count
2276 length of string rather than counting it via multiple sprintfs;
2277 that's simpler and more reliable.
2278 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
2279 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
2280 sprintf, in case result does not fit in int.
2281
2282 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
2283 (fontset_from_font): Print it.
2284
2285 * frame.c (tty_frame_count): Now printmax_t, not int.
2286 (make_terminal_frame, set_term_frame_name): Print it.
2287 (x_report_frame_params): In X, window IDs are unsigned long,
2288 not signed long, so print them as unsigned.
2289 (validate_x_resource_name): Check for implausibly long names,
2290 and don't assume name length fits in 'int'.
2291 (x_get_resource_string): Don't blindly alloca invocation name;
2292 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
2293 not fit in int.
2294
2295 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
2296 (xg_check_special_colors, xg_set_geometry):
2297 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
2298
2299 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
2300 Use esprintf, not sprintf, in case result does not fit in int.
2301
2302 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2303 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
2304 it as a large positive number.
2305 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
2306 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2307
2308 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
2309 in case result does not fit in int.
2310
2311 * print.c (float_to_string): Detect width overflow more reliably.
2312 (print_object): Make sprintf buffer a bit bigger, to avoid potential
2313 buffer overrun. Don't assume list length fits in 'int'. Treat
2314 print length of 0 as 0, not as infinity; to be consistent with other
2315 uses of print length in this function. Don't overflow print length
2316 index. Don't assume hash table size fits in 'long', or that
2317 vectorlike size fits in 'unsigned long'.
2318
2319 * process.c (make_process): Use printmax_t, not int, to format
2320 process-name gensyms.
2321
2322 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
2323
2324 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
2325 to avoid potential buffer overrun.
2326
2327 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
2328 if X resource line is longer than 512 bytes.
2329
2330 * xfns.c (x_window): Make sprintf buffer a bit bigger
2331 to avoid potential buffer overrun.
2332
2333 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
2334
2335 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
2336
2337 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2338
2339 Integer overflow fixes for scrolling, etc.
2340 Without these, Emacs silently mishandles large integers sometimes.
2341 For example, "C-u 4294967297 M-x recenter" was treated as if
2342 it were "C-u 1 M-x recenter" on a typical 64-bit host.
2343
2344 * xdisp.c (try_window_id): Check Emacs fixnum range before
2345 converting to 'int'.
2346
2347 * window.c (window_scroll_line_based, Frecenter):
2348 Check that an Emacs fixnum is in range before assigning it to 'int'.
2349 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
2350 values converted from Emacs fixnums.
2351 (Frecenter): Don't wrap around a line count if it is out of 'int'
2352 range; instead, treat it as an extreme value.
2353 (Fset_window_configuration, compare_window_configurations):
2354 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
2355
2356 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
2357 that can exceed INT_MAX. Check that EMACS_INT value is in range
2358 before assigning it to the (possibly-narrower) index.
2359 (match_limit): Don't assume that a fixnum can fit in 'int'.
2360
2361 * print.c (print_object): Use ptrdiff_t, not int, for index that can
2362 exceed INT_MAX.
2363
2364 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
2365 (Fvertical_motion): Don't wrap around LINES values that don't fit
2366 in 'int'. Instead, treat them as extreme values. This is good
2367 enough for windows, which can't have more than INT_MAX lines anyway.
2368
2369 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
2370
2371 * Require libxml/parser.h to avoid compilation warning.
2372
2373 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
2374
2375 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
2376 since this reportedly can destroy thread storage.
2377
2378 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
2379
2380 * syntax.c (find_defun_start): Update all cache variables if
2381 exiting early (Bug#9401).
2382
2383 2011-08-30 Eli Zaretskii <eliz@gnu.org>
2384
2385 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
2386
2387 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
2388 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
2389 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
2390
2391 * term.c (tty_append_glyph): New function.
2392 (produce_stretch_glyph): Static function and its prototype deleted.
2393
2394 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
2395 Add prototypes.
2396
2397 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
2398
2399 * image.c (parse_image_spec): Check for nonnegative, not for positive,
2400 when checking :margin (Bug#9390).
2401 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
2402 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
2403 so that the name doesn't mislead. All uses changed.
2404
2405 2011-08-28 Johan Bockgård <bojohan@gnu.org>
2406
2407 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
2408 set_tty_hooks.
2409
2410 2011-08-27 Eli Zaretskii <eliz@gnu.org>
2411
2412 * xdisp.c (move_it_to): Don't bail out early when reaching
2413 position beyond to_charpos, if we are scanning backwards.
2414 (move_it_vertically_backward): When DY == 0, make sure we get to
2415 the first character in the line after the newline.
2416
2417 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
2418
2419 * ccl.c: Improve and simplify overflow checking (Bug#9196).
2420 (ccl_driver): Do not generate an out-of-range pointer.
2421 (Fccl_execute_on_string): Remove unnecessary check for
2422 integer overflow, noted by Stefan Monnier in
2423 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
2424 Remove a FIXME that didn't need fixing.
2425 Simplify the newly-introduced buffer reallocation code.
2426
2427 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
2428
2429 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
2430
2431 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
2432
2433 Integer and memory overflow issues (Bug#9196).
2434
2435 * doc.c (get_doc_string): Rework so that
2436 get_doc_string_buffer_size is the actual buffer size, rather than
2437 being 1 less than the actual buffer size; this makes xpalloc more
2438 convenient.
2439
2440 * image.c (x_allocate_bitmap_record, cache_image):
2441 * xselect.c (Fx_register_dnd_atom):
2442 Simplify previous changes by using xpalloc.
2443
2444 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
2445 since either will do and ptrdiff_t is convenient with xpalloc.
2446
2447 * charset.c (charset_table_size)
2448 (struct charset_sort_data.priority): Now ptrdiff_t.
2449 (charset_compare): Don't overflow if priorities differ greatly.
2450 (Fsort_charsets): Don't assume list length fits in int.
2451 Check for size-calculation overflow when allocating sort data.
2452 (syms_of_charset): Allocate an initial charset table that is
2453 just under 64 KiB, to avoid problems with glibc malloc and mmap.
2454
2455 * cmds.c (internal_self_insert): Check for size-calculation overflow.
2456
2457 * composite.h (struct composition.glyph_len): Now int, not unsigned.
2458 The actual value is always <= INT_MAX, and leaving it unsigned made
2459 overflow checking harder.
2460
2461 * dispextern.h (struct glyph_matrix.rows_allocated)
2462 (struct face_cache.size): Now ptrdiff_t, for convenience in use
2463 with xpalloc. The values are still always <= INT_MAX.
2464
2465 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
2466
2467 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
2468 (SAFE_NALLOCA): New macro.
2469
2470 * region-cache.c (struct boundary.pos, find_cache_boundary)
2471 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
2472 (set_cache_region, invalidate_region_cache)
2473 (revalidate_region_cache, know_region_cache, region_cache_forward)
2474 (region_cache_backward, pp_cache):
2475 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
2476 so that ptrdiff_t * can be passed to xpalloc.
2477 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
2478 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
2479 (pp_cache): Don't assume cache_len fits in int.
2480 * region-cache.h: Adjust extern decls to match.
2481
2482 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
2483 EMACS_INT, since either will do, for xpalloc.
2484
2485 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
2486 (xnmalloc, xnrealloc, xpalloc): New functions.
2487
2488 * bidi.c (bidi_shelve_header_size): New constant.
2489 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
2490 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
2491
2492 * bidi.c (bidi_cache_shrink):
2493 * buffer.c (overlays_at, overlays_in, record_overlay_string)
2494 (overlay_strings):
2495 Don't update size of array until after memory allocation succeeds,
2496 because xmalloc/xrealloc may not return.
2497 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
2498 now that we have proper integer overflow checking.
2499 (record_overlay_string, overlay_strings): Catch overflows when
2500 calculating size of overlay_str_buf.
2501
2502 * callproc.c (Fcall_process): Check for size overflow when
2503 calculating size of args2.
2504 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
2505 Normally we prefer signed values, but sticking with ptrdiff_t would
2506 require adding more-complicated checks.
2507
2508 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
2509 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
2510 Redo buffer-overflow calculations to avoid integer overflow.
2511 Add a FIXME comment where memory seems to be over-allocated.
2512
2513 * character.c (Fstring): Check for size-calculation overflow.
2514
2515 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
2516 unnecessary integer overflow. Check for size overflow.
2517 (encode_coding_object): Don't update size until xmalloc succeeds.
2518
2519 * composite.c (get_composition_id): Check for overflow in glyph
2520 length calculations.
2521
2522 Integer and memory overflow fixes for display code.
2523 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
2524 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
2525 (scrolling_window): Check for overflow in size calculations.
2526 (line_draw_cost, realloc_glyph_pool, add_row_entry):
2527 Don't assume glyph table len fits in int.
2528 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
2529 (row_table_size): Now ptrdiff_t, not int.
2530 (scrolling_window): Avoid overflow in size calculations.
2531 Don't update size until allocation succeeds.
2532 * fns.c (concat): Check for overflow in size calculations.
2533 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
2534 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
2535 (NEXT_ALMOST_PRIME_LIMIT): New constant.
2536
2537 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
2538 (get_doc_string): Check for size calculation overflow.
2539 Don't update size until allocation succeeds.
2540 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
2541 EMACS_INT, where ptrdiff_t will do.
2542 (Fsubstitute_command_keys): Check for string overflow.
2543
2544 * editfns.c (set_time_zone_rule): Don't assume environment length
2545 fits in int.
2546 (message_length): Now ptrdiff_t, not int.
2547 (Fmessage_box): Don't update size until allocation succeeds.
2548 Don't assume message length fits in int.
2549 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
2550
2551 * emacs.c (main): Do not reallocate argv, since there is a null at
2552 the end that can be overwritten, and this way there's no need to
2553 worry about size-calculation overflow.
2554 (sort_args): Check for size-calculation overflow.
2555
2556 * eval.c (init_eval_once, grow_specpdl): Don't update size until
2557 alloc succeeds.
2558 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
2559
2560 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
2561 (x_set_scroll_bar_width, x_figure_window_size):
2562 Check for integer overflow.
2563 (x_set_alpha): Do not assume XINT fits in int.
2564
2565 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
2566 This is for the members text_lines, text_cols, total_lines, total_cols,
2567 where the system imposes an 'int' limit.
2568
2569 * fringe.c (Fdefine_fringe_bitmap):
2570 Don't update size until alloc works.
2571
2572 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
2573 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
2574

2634 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
2635 for command line length. Do not attempt to address one before the
2636 beginning of an array, as that's not portable.
2637
2638 * term.c (max_frame_lines): Remove; unused.

2668 memory exhaustion (the usual treatment), rather than aborting.
2669
2670 * xfns.c (x_encode_text, x_set_name_internal)
2671 (Fx_change_window_property): Use ptrdiff_t, not int, to count
2672 sizes, since they can exceed INT_MAX in size. Check for size

2676 (xg_select): Check for size calculation overflow.
2677 Don't update size until alloc done.
2678
2679 * xrdb.c (get_environ_db): Don't assume path length fits in int,

2681
2682 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
2683 (X_LONG_MIN): New macros.
2684 Use them to make the following changes clearer.
2685 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
2686 This change doesn't affect the value now, but it may help remind
2687 future maintainers not to raise the value too much later.
2688 (SELECTION_QUANTUM): Remove, replacing with ...
2689 (selection_quantum): ... new function, which avoids overflow.
2690 All uses changed.
2691 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
2692 assumption that selection length fits in 'int'.
2693 (x_reply_selection_request, x_handle_selection_request)
2694 (x_get_window_property, receive_incremental_selection)

2700 Redo calculations to avoid overflow.
2701 (x_reply_selection_request): When sending hint, ceiling it at

2709 Don't store size until memory allocation succeeds.
2710 (x_get_window_property): Plug memory leak on memory exhaustion.
2711 Don't double-block input; malloc is safe here. Don't assume 2**34
2712 - 4 fits in unsigned long. Add an xassert to check
2713 XGetWindowProperty overflow. Be more careful about overflow
2714 calculations, and distinguish size from memory overflow better.
2715 (receive_incremental_selection): When tracing, don't assume
2716 unsigned int is less than INT_MAX.
2717 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
2718 harmful) conversions of unsigned short to int.

2720 in the range -65535 through -1 fit in an X unsigned short.
2721 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
2722 result parameters unless successful. Rely on cons_to_unsigned
2723 to report problems with elements; the old code wasn't right anyway.
2724 (x_check_property_data): Check for int overflow; we cannot use
2725 a wider type due to X limits.

2758 * lisp.h (hash_lookup, hash_put):
2759 * minibuf.c (Ftest_completion):
2760 Use ptrdiff_t for hash table indexes, not int (which is too
2761 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
2762 32-bit --with-wide-int hosts).
2763
2764 * charset.c (Fdefine_charset_internal): Check for integer overflow.
2765 Add a FIXME comment about memory leaks.
2766 (syms_of_charset): Don't assume xmalloc returns.

2773 with outlandish widths.
2774 * character.h (sanitize_tab_width): Rename from sanitize_width,
2775 now that we have two such functions. All uses changed.

2794 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
2795 (x_send_scroll_bar_event): Likewise. Check that the size does not
2796 exceed limits imposed by XClientMessageEvent, as well as the usual
2797 ptrdiff_t and size_t limits.
2798
2799 * keyboard.c: Overflow, signedness and related fixes.
2800 (make_lispy_movement): Use same integer type in forward decl
2801 that is used in the definition.
2802 (read_key_sequence, keyremap_step):
2803 Change bufsize argument back to int, undoing my 2011-03-30 change.
2804 We prefer signed types, and int is wide enough here.
2805 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
2806 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
2807 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
2808 length, not size_t. Use ptrdiff_t for index, not int.
2809 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
2810 possibility of integer overflow.

2833 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
2834 (lookup_image): Remove unnecessary tests.
2835 (xbm_image_p): Locals are now of int, not EMACS_INT,
2836 since parse_image_check makes sure they fit into int.
2837 (png_load, gif_load, svg_load_image):
2838 Prefer int to unsigned where either will do.
2839 (tiff_handler): New function, combining the cores of the
2840 old tiff_error_handler and tiff_warning_handler.
2841 This function is rewritten to use vsnprintf and thereby avoid
2842 stack buffer overflows. It uses only the features of vsnprintf
2843 that are common to both POSIX and native Microsoft.
2844 (tiff_error_handler, tiff_warning_handler): Use it.
2845 (tiff_load, gif_load, imagemagick_load_image):
2846 Don't assume :index value fits in 'int'.
2847 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
2848 (imagemagick_load_image): Check that crop parameters fit into
2849 the integer types that MagickCropImage accepts. Don't assume
2850 Vimagemagick_render_type has a nonnegative value. Don't assume
2851 size_t fits in 'long'.
2852 (gs_load): Use printmax_t to print the widest integers possible.

2865 handle_single_display_spec, not just 1 or zero.
2866 (handle_single_display_spec): If the display spec is of the form
2867 `(space ...)', and specifies display in the text area, return 2
2868 rather than 1.
2869 (try_cursor_movement): Check for the need to scroll more
2870 accurately, and prefer exact match for point under bidi.
2871 Don't advance `row' beyond the last row of the window.
2872

2889 buffers, return left-to-right.
2890 (set_cursor_from_row): Consider candidate row a win if its glyph

2892 positioning on the newline at EOL of R2L text within L2R
2893 paragraph, and vice versa.
2894 (try_cursor_movement): Check continued rows, in addition to
2895 continuation rows. Fixes unwarranted scroll when point enters a
2896 continued line of R2L text within an L2R paragraph, or vice versa.
2897 (cursor_row_p): Consider the case of point being equal to
2898 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
2899 from the end of a short line to the beginning of a continued line
2900 of R2L text within L2R paragraph.
2901 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
2902 composed characters.

2923
2924 * xdisp.c (redisplay_window): When computing centering_position,
2925 account for the height of the header line. (Bug#8874)
2926
2927 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
2928 instead of CHAR_TO_BYTE. Fixes a crash when a completion
2929 candidate is selected by the mouse, and that candidate has a
2930 composed character under the mouse.
2931
2932 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
2933 coordinates reported by pos-visible-in-window-p for a composed
2934 character in column zero.
2935
2936 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

2940 2011-08-22 Eli Zaretskii <eliz@gnu.org>
2941
2942 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
2943 consider it a hit if to_charpos is anywhere in the range of the
2944 composed buffer positions.
2945
2946 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
2947
2948 * image.c (gif_load): Don't assume that each subimage has the same
2949 dimensions as the base image. Handle disposal method that is
2950 "undefined" by the gif spec (Bug#9335).
2951
2952 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

2961 from an Org mode buffer to a Speedbar frame.
2962
2963 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
2964 a composition, take its buffer position from IT->cmp_it.charpos.

2966 with a composed character.
2967
2968 2011-08-18 Eli Zaretskii <eliz@gnu.org>
2969
2970 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
2971 character bidirectional type, use STRONG_L instead. Fixes crashes
2972 in a buffer produced by `describe-categories'.
2973
2974 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
2975 members before the level stack, so they would be saved and
2976 restored when copying iterator state. Fixes incorrect reordering
2977 around TABs covered by display properties.
2978
2979 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
2980

2991 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
2992 has no `load' handler, try opening the file locally. (Bug#9311)
2993
2994 2011-08-16 Ken Brown <kbrown@cornell.edu>
2995
2996 * gmalloc.c: Expand comment.
2997
2998 2011-08-16 Eli Zaretskii <eliz@gnu.org>
2999
3000 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
3001 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
3002
3003 2011-08-16 Ken Brown <kbrown@cornell.edu>
3004
3005 Fix memory allocation problems in Cygwin build (Bug#9273).
3006
3007 * unexcw.c ( __malloc_initialized): Declare external variable.
3008 (fixup_executable): Force the dumped emacs to reinitialize malloc.
3009
3010 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
3011 New variables.
3012 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
3013 dumped emacs.

3015 in the static heap.
3016 [CYGWIN] (special_realloc): New function.
3017 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
3018 requests to realloc storage in the static heap.
3019
3020 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>

3031 * dispextern.h: Fix a typo in the comment to bidi_type_t.
3032
3033 * chartab.c: Improve commentary for the uniprop_table API.
3034
3035 * bidi.c (bidi_paragraph_init): Support zero value of
3036 bidi_ignore_explicit_marks_for_paragraph_level.
3037 (bidi_initialize): Use uniprop_table instead of including
3038 biditype.h and bidimirror.h.
3039
3040 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
3041 coordinates of the iterator when restoring from ppos_it.
3042 (Bug#9296)
3043
3044 2011-08-14 Kenichi Handa <handa@m17n.org>
3045
3046 * process.c (create_process): Call setup_process_coding_systems
3047 after the pid of the process is set to -1 (Bug#8162).
3048
3049 2011-08-14 Eli Zaretskii <eliz@gnu.org>
3050
3051 * xdisp.c (move_it_in_display_line_to): Don't invoke
3052 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
3053 ppos_it. Fixes vertical cursor motion when line beginning is
3054 covered by an image. (Bug#9296)
3055
3056 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
3057
3058 * nsterm.h (ns_run_ascript): Declare.
3059 (NSAPP_DATA2_RUNASSCRIPT): Define.
3060
3061 * nsfns.m (as_script, as_result, as_status): New static variables.
3062 (ns_run_ascript): New function.
3063 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
3064 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
3065 the event loop. Get status from as_status (Bug#7276).
3066
3067 * nsterm.m (sendEvent): If event is NSApplicationDefined and
3068 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
3069 the event loop (Bug#7276).
3070
3071 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
3072
3073 * gnutls.c (QCgnutls_bootprop_priority)
3074 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
3075 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
3076 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
3077 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
3078 (QCgnutls_bootprop_verify_hostname_error)
3079 (QCgnutls_bootprop_callbacks_verify): Rename from
3080 Qgnutls_bootprop_..., all uses changed.
3081
3082 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
3083 uses changed.
3084
3085 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
3086
3087 * xfaces.c (Qframe_set_background_mode): Now static.
3088 * dispextern.h (Qframe_set_background_mode): Remove decl.
3089
3090 * process.c (Fnetwork_interface_info): Declare local only if needed.
3091
3092 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
3093
3094 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
3095 (Fnetwork_interface_list): Allocate in increments of bytes instead
3096 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
3097 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
3098 sockaddr.
3099 (struct ifflag_def): notrailers is smart on OSX.
3100 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
3101 Get hardware address with getifaddrs if available.
3102
3103 2011-08-12 Eli Zaretskii <eliz@gnu.org>
3104
3105 * xdisp.c (iterate_out_of_display_property): xassert that
3106 IT->position is set to within IT->object's boundaries. Break from
3107 the loop as soon as EOB is reached; avoids infloops in redisplay
3108 when IT->position is set up wrongly due to some bug.
3109 Set IT->current to match the bidi iterator unconditionally.
3110 (push_display_prop): Allow GET_FROM_STRING as IT->method on
3111 entry. Force push_it to save on the stack the current
3112 buffer/string position, to be restored by pop_it. Fix flags in
3113 the iterator structure wrt the object coming from a display
3114 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
3115 properties. (Bug#9284)
3116
3117 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
3118
3119 * fontset.c (fontset_get_font_group): Add proper type checks.
3120 (Bug#9172)
3121

3123
3124 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
3125 and LC_VERSION_MIN_MACOSX.
3126 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
3127 (dump_it) [LC_FUNCTION_STARTS]: Use it.
3128
3129 2011-08-08 Eli Zaretskii <eliz@gnu.org>
3130
3131 * xdisp.c (forward_to_next_line_start): Allow to use the
3132 no-display-properties-and-no-overlays under bidi display.
3133 Set disp_pos in the bidi iterator to avoid searches for display
3134 properties and overlays.
3135
3136 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
3137
3138 * editfns.c (Fset_time_zone_rule): Document relationship with the
3139 setenv function.
3140
3141 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
3142 the font entity extracted from the cache (Bug#8109).
3143
3144 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
3145
3146 * composite.c (autocmp_chars): Don't reset point. That is done by
3147 restore_point_unwind (Bug#5984).
3148
3149 2011-08-07 Juri Linkov <juri@jurta.org>
3150
3151 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
3152 to show the arg `TIME' instead of `TIMEVAL'.
3153
3154 2011-08-06 Eli Zaretskii <eliz@gnu.org>
3155
3156 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
3157 display property strides EOL and includes a newline, as in
3158 longlines-mode. (Bug#9254)
3159 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
3160 word-wrap under bidirectional display. (Bug#9224)
3161
3162 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
3163 is non-zero, even if the data buffer is NULL. Fixes a crash in
3164 vertical-motion with longlines-mode. (Bug#9254)
3165
3166 2011-08-05 Eli Zaretskii <eliz@gnu.org>
3167
3168 * bidi.c <bidi_cache_total_alloc>: Now static.
3169 (bidi_initialize): Initialize bidi_cache_total_alloc.
3170
3171 * xdisp.c (display_line): Release buffer allocated for shelved bidi
3172 cache. (Bug#9221)
3173
3174 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
3175 amount allocated this far in `bidi_cache_total_alloc'.
3176 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
3177 non-zero, only free the data buffer without restoring the cache
3178 contents. All callers changed.
3179
3180 * dispextern.h (bidi_unshelve_cache): Update prototype.
3181
3182 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
3183 (move_it_in_display_line, move_it_to)
3184 (move_it_vertically_backward, move_it_by_lines): Replace the call
3185 to xfree to an equivalent call to bidi_unshelve_cache.
3186 (move_it_in_display_line_to): Fix logic of returning
3187 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
3188
3189 2011-08-05 Eli Zaretskii <eliz@gnu.org>
3190
3191 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
3192 came from a string character with a `cursor' property. (Bug#9229)
3193
3194 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
3195
3196 * Makefile.in (LIB_PTHREAD): New variable.
3197 (LIBES): Add LIB_PTHREAD (Bug#9216).
3198
3199 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
3200 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
3201
3202 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
3203
3204 * regex.c (re_iswctype): Remove some redundant boolean conversions.
3205
3206 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
3207
3208 * xterm.c (x_find_topmost_parent): New function.
3209 (x_set_frame_alpha): Find topmost parent window with
3210 x_find_topmost_parent and set the property there also (bug#9181).
3211 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
3212
3213 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
3214
3215 * callproc.c (Fcall_process): Avoid vfork clobbering
3216 the local vars buffer, coding_systems, current_dir.
3217
3218 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
3219
3220 * keymap.c (Fmake_composed_keymap): Move to subr.el.
3221
3222 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
3223
3224 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
3225 so that it is not optimized away.
3226
3227 * xdisp.c (compute_display_string_pos): Remove unused local.
3228
3229 2011-08-02 Eli Zaretskii <eliz@gnu.org>
3230
3231 Fix slow cursor motion and scrolling in large buffers with
3232 selective display, like Org Mode buffers. (Bug#9218)
3233
3234 * dispextern.h (struct bidi_it): New member disp_prop_p.
3235
3236 * xdisp.c: Remove one-slot cache of display string positions.
3237 (compute_display_string_pos): Accept an additional argument
3238 DISP_PROP_P; callers changed. Scan at most 5K characters forward
3239 for a display string or property. If found, set DISP_PROP_P
3240 non-zero.
3241
3242 * bidi.c (bidi_fetch_char): Accept an additional argument
3243 DISP_PROP_P, and pass it to compute_display_string_pos.
3244 Only handle text covered by a display string if DISP_PROP_P is returned
3245 non-zero. All callers of bidi_fetch_char changed.
3246
3247 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
3248
3249 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
3250
3251 2010-12-03 Don March <don@ohspite.net>
3252
3253 * keymap.c (Fdefine_key): Fix non-prefix key error message when
3254 last character M-[char] is translated to ESC [char] (bug#7541).
3255
3256 2011-08-02 Kenichi Handa <handa@m17n.org>
3257
3258 * lisp.h (uniprop_table): Extern it.
3259
3260 * chartab.c (uniprop_table): Make it non-static.
3261
3262 2011-08-01 Eli Zaretskii <eliz@gnu.org>
3263
3264 * xdisp.c (forward_to_next_line_start): Accept additional argument
3265 BIDI_IT_PREV, and store into it the state of the bidi iterator had
3266 on the newline.
3267 (reseat_at_next_visible_line_start): Use the bidi iterator state
3268 returned by forward_to_next_line_start to restore the state of
3269 it->bidi_it after backing up to previous newline. (Bug#9212)
3270
3271 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
3272
3273 * regex.c (re_comp): Protoize.
3274 (re_exec): Fix return type.
3275 (regexec): Fix type of `ret'. (Bug#9203)
3276
3277 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3278
3279 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
3280 This is needed if max-image-size is a floating-point number.
3281
3282 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3283
3284 * print.c (print_object): Print empty symbol as ##.
3285
3286 * lread.c (read1): Read ## as empty symbol.
3287
3288 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3289
3290 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
3291 setting frame foreground color (Bug#9175).
3292 (x_set_background_color): Likewise.
3293
3294 * nsmenu.m (-setText): Size tooltip dimensions precisely to
3295 contents (Bug#9176).
3296 (EmacsTooltip -init): Remove bezels and add shadows to
3297 tooltip windows.
3298
3299 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
3300 or scroll bar (Bug#8470).
3301
3302 * nsfont.m (nsfont_open): Remove assignment to voffset and
3303 unnecessary vars hshink, expand, hd, full_height, min_height.
3304 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
3305
3306 * nsterm.h (nsfont_info): Remove voffset field.
3307
3308 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3309
3310 Implement strike-through and overline on NextStep (Bug#8863).
3311
3312 * nsfont.m (nsfont_open): Use underline position provided by font,
3313 instead of hard-coded value of 2.
3314 (nsfont_draw): Call ns_draw_text_decoration instead.
3315
3316 * nsterm.h: Add declaration for ns_draw_text_decoration.
3317
3318 * nsterm.m (ns_draw_text_decoration): New function for drawing
3319 underline, overline, and strike-through.
3320 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to

3322 accommodate underlining, etc.
3323
3324 2011-07-28 Eli Zaretskii <eliz@gnu.org>
3325
3326 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
3327 default.
3328
3329 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3330
3331 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
3332 Without this fix, if a signal arrives just after memory fills up,
3333 'malloc' might be invoked reentrantly.
3334
3335 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
3336 In other words, assume that every image size is allowed, on non-X
3337 hosts. This assumption is probably wrong, but it lets Emacs compile.
3338
3339 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3340
3341 * regex.c (re_iswctype): Convert return values to boolean.
3342
3343 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
3344
3345 * xdisp.c (compute_display_string_pos): Don't use cached display
3346 string position if the buffer had its restriction changed.
3347 (Bug#9184)
3348
3349 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3350
3351 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3352
3353 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3354
3355 Integer signedness and overflow and related fixes. (Bug#9079)
3356
3357 * bidi.c: Integer size and overflow fixes.
3358 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
3359 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
3360 (bidi_cache_find_level_change, bidi_cache_ensure_space)
3361 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
3362 (bidi_find_other_level_edge):
3363 Use ptrdiff_t instead of EMACS_INT where either will do.
3364 This works better on 32-bit hosts configured --with-wide-int.
3365 (bidi_cache_ensure_space): Check for size-calculation overflow.
3366 Use % rather than repeated addition, for better worst-case speed.
3367 Don't set bidi_cache_size until after xrealloc returns, because it
3368 might not return.
3369 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
3370 (bidi_cache_ensure_space): Also check that the bidi cache size
3371 does not exceed that of the largest Lisp string or buffer. See Eli
3372 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
3373
3374 * alloc.c (__malloc_size_t): Remove.
3375 All uses replaced by size_t. See Andreas Schwab's note
3376 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
3377
3378 * image.c: Improve checking for integer overflow.
3379 (check_image_size): Assume that f is nonnull, since
3380 it is always nonnull in practice. This is one less thing to
3381 worry about when checking for integer overflow later.
3382 (x_check_image_size): New function, which checks for integer
3383 overflow issues inside X.
3384 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
3385 This removes the need for a memory_full check.
3386 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
3387 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
3388 (xbm_read_bitmap_data): Change locals back to 'int', since
3389 their values must fit in 'int'.
3390 (xpm_load_image, png_load, tiff_load):
3391 Invoke x_create_x_image_and_pixmap earlier,
3392 to avoid much needless work if the image is too large.
3393 (tiff_load): Treat overly large images as if
3394 x_create_x_image_and_pixmap failed, not as malloc failures.
3395 (gs_load): Use x_check_image_size.
3396
3397 * gtkutil.c: Omit integer casts.
3398 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
3399 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
3400
3401 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
3402
3403 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
3404 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
3405 would wrongly return t on a 64-bit host.
3406
3407 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
3408 The plain *_OVERFLOW macros run afoul of GCC bug 49705
3409 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
3410 and therefore cause GCC to emit a bogus diagnostic in some cases.
3411
3412 * image.c: Integer signedness and overflow and related fixes.
3413 This is not an exhaustive set of fixes, but it's time to
3414 record what I've got.
3415 (lookup_pixel_color, check_image_size): Remove redundant decls.
3416 (check_image_size): Don't assume that arbitrary EMACS_INT values
3417 fit in 'int', or that arbitrary 'double' values fit in 'int'.
3418 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
3419 (tiff_load, imagemagick_load_image):
3420 Check for overflow in size calculations.
3421 (x_create_x_image_and_pixmap): Remove unnecessary test for
3422 xmalloc returning NULL; that can't happen.
3423 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
3424 (xpm_color_bucket): Use better integer hashing function.
3425 (xpm_cache_color): Don't possibly over-allocate memory.
3426 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
3427 (gif_memory_source):
3428 Use ptrdiff_t, not int or size_t, to record sizes.
3429 (png_load): Don't assume values greater than 2**31 fit in 'int'.
3430 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
3431 either works, as we prefer signed integers.
3432 (tiff_read_from_memory, tiff_write_from_memory):
3433 Return tsize_t, not size_t, since that's what the TIFF API wants.
3434 (tiff_read_from_memory): Don't fail simply because the read would
3435 go past EOF; instead, return a short read.
3436 (tiff_load): Omit no-longer-needed casts.
3437 (Fimagemagick_types): Don't assume size fits into 'int'.
3438
3439 Improve hashing quality when configured --with-wide-int.
3440 * fns.c (hash_string): New function, taken from sxhash_string.
3441 Do not discard information about ASCII character case; this
3442 discarding is no longer needed.
3443 (sxhash-string): Use it. Change sig to match it. Caller changed.
3444 * lisp.h: Declare it.
3445 * lread.c (hash_string): Remove, since we now use fns.c's version.
3446 The fns.c version returns a wider integer if --with-wide-int is
3447 specified, so this should help the quality of the hashing a bit.
3448
3449 * emacs.c: Integer overflow minor fix.
3450 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
3451 Define only if GNU_LINUX.
3452 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
3453
3454 * dispnew.c: Integer signedness and overflow fixes.
3455 Remove unnecessary forward decls, that were a maintenance hassle.
3456 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
3457 All uses changed.
3458 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
3459 (scrolling_window): Use ptrdiff_t, not int, for byte count.
3460 (prepare_desired_row, line_draw_cost):
3461 Use int, not unsigned, where either works.
3462 (save_current_matrix, restore_current_matrix):
3463 Use ptrdiff_t, not size_t, where either works.
3464 (init_display): Check for overflow more accurately, and without
3465 relying on undefined behavior.
3466
3467 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
3468 Remove, replacing with the new symbols in lisp.h. All uses changed.
3469 * fileio.c (make_temp_name):
3470 * filelock.c (lock_file_1, lock_file):
3471 * xdisp.c (message_dolog):
3472 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
3473 Use pMd etc. instead.
3474 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
3475 replacing the pWIDE etc. symbols removed from editfns.c.
3476
3477 * keyboard.h (num_input_events): Now uintmax_t.
3478 This is (very slightly) less likely to mess up due to wraparound.
3479 All uses changed.
3480
3481 * buffer.c: Integer signedness fixes.
3482 (alloc_buffer_text, enlarge_buffer_text):
3483 Use ptrdiff_t rather than size_t when either will do, as we prefer
3484 signed integers.
3485
3486 * alloc.c: Integer signedness and overflow fixes.
3487 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
3488 (__malloc_size_t): Default to size_t, not to int.
3489 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
3490 (Fgarbage_collect, mark_object_loop_halt, mark_object):
3491 Prefer ptrdiff_t to size_t when either would do, as we prefer
3492 signed integers.
3493 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
3494 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
3495 Now const. Initialize with values that are in range even if char
3496 is signed.
3497 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
3498 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
3499 These functions do the right thing with sizes > 2**32.
3500 (check_depth): Now ptrdiff_t, not int.
3501 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
3502 Adjust to new way of storing sizes. Check for size overflow bugs
3503 in rest of code.
3504 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
3505 slightly wrong anyway, as it missed one instance of
3506 XMALLOC_OVERRUN_CHECK_OVERHEAD.
3507 (refill_memory_reserve): Omit needless cast to size_t.
3508 (mark_object_loop_halt): Mark as externally visible.
3509
3510 * xselect.c: Integer signedness and overflow fixes.
3511 (Fx_register_dnd_atom, x_handle_dnd_message):
3512 Use ptrdiff_t, not size_t, since we prefer signed.
3513 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
3514 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
3515 x_dnd_atoms_size and x_dnd_atoms_length.
3516
3517 * doprnt.c: Prefer signed to unsigned when either works.
3518 * eval.c (verror):
3519 * doprnt.c (doprnt):
3520 * lisp.h (doprnt):
3521 * xdisp.c (vmessage):
3522 Use ptrdiff_t, not size_t, when using or implementing doprnt,
3523 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
3524 prefer signed arithmetic to avoid comparison confusion.
3525 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
3526 but is a bit tricky.
3527
3528 Assume freestanding C89 headers, string.h, stdlib.h.
3529 * data.c, doprnt.c, floatfns.c, print.c:
3530 Include float.h unconditionally.
3531 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
3532 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
3533 * regex.c: Likewise for stddef.h, string.h.
3534 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
3535 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
3536 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
3537 (STDC_HEADERS): Remove obsolete defines.
3538 * sysdep.c: Include limits.h unconditionally.
3539
3540 Assume support for memcmp, memcpy, memmove, memset.
3541 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
3542 * regex.c (memcmp, memcpy):
3543 Remove; we assume C89 now.
3544
3545 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
3546 (__malloc_safe_bcopy): Remove; no longer needed.
3547
3548 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
3549 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
3550 well either way, and we prefer signed to unsigned.
3551
3552 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
3553
3554 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
3555 closes the connection while we're reading (bug#9182).
3556
3557 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
3558
3559 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
3560 are specified (Bug#9168).
3561
3562 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
3563
3564 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
3565 Found by GCC static checking and --with-wide-int on a 32-bit host.
3566
3567 2011-07-25 Eli Zaretskii <eliz@gnu.org>
3568
3569 * xdisp.c (compute_display_string_pos): Fix logic of caching
3570 previous display string position. Initialize cached_prev_pos to
3571 -1. Fixes slow-down at the beginning of a buffer.
3572
3573 2011-07-24 Eli Zaretskii <eliz@gnu.org>
3574
3575 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
3576 for attrs[LFACE_FONTSET_INDEX].
3577
3578 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
3579
3580 * xml.c (parse_region): Remove unused local
3581 that was recently introduced.
3582
3583 2011-07-23 Eli Zaretskii <eliz@gnu.org>
3584
3585 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
3586 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
3587
3588 * xdisp.c (move_it_in_display_line_to): Record the best matching
3589 position for TO_CHARPOS while scanning the line, and restore it on
3590 exit if none of the characters scanned was an exact match.
3591 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
3592 when exact match is impossible due to invisible text, and the
3593 lines are truncated.
3594
3595 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
3596
3597 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
3598 for OSX >= 10.7.
3599
3600 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3601
3602 Fix a significant slow-down of cursor motion with C-n, C-p,
3603 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
3604 auto-repeat under bidi redisplay in fontified buffers.
3605 * xdisp.c (compute_stop_pos_backwards): New function.
3606 (next_element_from_buffer): Call compute_stop_pos_backwards to
3607 find a suitable prev_stop when we find ourselves before
3608 base_level_stop.
3609 (reseat): Don't look for prev_stop, as that could mean a very long
3610 run.
3611 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
3612 <cached_disp_overlay_modiff>: Cache for last found display string
3613 position.
3614 (compute_display_string_pos): Return the cached position if asked
3615 about the same buffer in the same area of character positions, and
3616 the buffer wasn't changed since the time the display string
3617 position was cached.
3618
3619 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3620
3621 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
3622 is an integer, which is important for empty lines. (Bug#9149)
3623
3624 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
3625
3626 * frame.c (Fmodify_frame_parameters): In tty case, update the
3627 default face if necessary (Bug#4238).
3628
3629 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
3630
3631 * editfns.c (Fstring_to_char): No need to explain what a character
3632 is in the docstring (Bug#6576).
3633
3634 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3635
3636 * xml.c (parse_region): Make sure we always return a tree.
3637
3638 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
3639
3640 * xml.c (parse_region): If a document contains only comments,
3641 return that, too.
3642
3643 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3644
3645 * xml.c (make_dom): Return comments, too.
3646
3647 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
3648
3649 Port to OpenBSD.
3650 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
3651 and the surrounding thread.
3652 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
3653 rather than fgets, and retry after EINTR. Otherwise, 'emacs
3654 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
3655 timer goes off.
3656 * s/openbsd.h (BROKEN_SIGIO): Define.
3657 * unexelf.c (unexec) [__OpenBSD__]:
3658 Don't update the .mdebug section of the Alpha COFF symbol table.
3659
3660 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
3661
3662 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
3663 (bug#8460).
3664
3665 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
3666
3667 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
3668 This fixes some race conditions on the permissions of any newly
3669 created file.
3670
3671 * alloc.c (valid_pointer_p): Use pipe, not open.
3672 This fixes some permissions issues when debugging.
3673
3674 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
3675 If fchown fails to set both uid and gid, try to set just gid,
3676 as that is sometimes allowed. Adjust the file's mode to eliminate
3677 setuid or setgid bits that are inappropriate if fchown fails.
3678
3679 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3680
3681 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
3682 to compare Lisp_Objects.
3683 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
3684 global_gnutls_log_level, don't mistake it for a Lisp_Object.
3685 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
3686
3687 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
3688
3689 * lread.c (read_integer): Unread even EOF character.
3690 (read1): Likewise. Properly record start position of symbol.
3691
3692 * lread.c (read1): Read `#:' as empty uninterned symbol if no
3693 symbol character follows.
3694
3695 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
3696
3697 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
3698 This works around a problem with the previous change to Fcopy_file.
3699 Recent glibc declares fchown with __attribute__((warn_unused_result)),
3700 and without this change, GCC might complain about discarding
3701 fchown's return value.
3702
3703 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
3704
3705 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
3706
3707 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
3708
3709 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
3710
3711 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
3712
3713 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
3714 it's used from the C level.
3715
3716 * process.c: Use the same condition for POLL_FOR_INPUT in both
3717 keyboard.c and process.c (bug#1858).
3718
3719 2011-07-09 Lawrence Mitchell <wence@gmx.li>
3720
3721 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
3722 (Fgnutls_boot): Use it.
3723
3724 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
3725
3726 * doc.c (Fsubstitute_command_keys): Revert last change.
3727
3728 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
3729
3730 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
3731 quotes the next character, and doesn't affect other longer
3732 sequences (bug#8935).
3733
3734 * lread.c (syms_of_lread): Clarify that is isn't only
3735 `eval-buffer' and `eval-defun' that's affected by
3736 `lexical-binding' (bug#8460).
3737
3738 2011-07-15 Eli Zaretskii <eliz@gnu.org>
3739
3740 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
3741 bidi redisplay when a line includes both an image and is truncated.
3742
3743 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
3744
3745 Fix minor problems found by static checking.
3746 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
3747 (elsz): Now a signed constant, not a size_t var. We prefer signed
3748 types to unsigned, to avoid integer comparison confusion. Without
3749 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
3750 "cannot optimize loop, the loop counter may overflow", a symptom
3751 of the confusion.
3752 * indent.c (Fvertical_motion): Mark locals as initialized.
3753 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
3754
3755 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
3756
3757 * search.c (Fre_search_backward): Mention `case-fold-search' in
3758 all the re_search_* functions (bug#8138).
3759
3760 * keyboard.c (Fopen_dribble_file): Document when the file is
3761 closed (bug#8056).
3762
3763 2011-07-14 Eli Zaretskii <eliz@gnu.org>
3764
3765 * bidi.c (bidi_dump_cached_states): Fix format of displaying
3766 bidi_cache_idx.
3767
3768 Support bidi reordering of display and overlay strings.
3769 * xdisp.c (compute_display_string_pos)
3770 (compute_display_string_end): Accept additional argument STRING.
3771 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
3772 (reseat_to_string): Initialize bidi_it->string.s and
3773 bidi_it->string.schars.
3774 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
3775 NULL (avoids a crash in bidi_paragraph_init).
3776 Initialize itb.string.lstring.
3777 (init_iterator): Call bidi_init_it only of a valid
3778 buffer position was specified. Initialize paragraph_embedding to
3779 L2R.
3780 (reseat_to_string): Initialize the bidi iterator.
3781 (display_string): If we need to ignore text properties of
3782 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
3783 original value of -1 will not work with bidi.)
3784 (compute_display_string_pos): First arg is now struct
3785 `text_pos *'; all callers changed. Support display properties on
3786 Lisp strings.
3787 (compute_display_string_end): Support display properties on Lisp
3788 strings.
3789 (init_iterator, reseat_1, reseat_to_string): Initialize the
3790 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
3791 when iterating on a string not from display properties).
3792 (compute_display_string_pos, compute_display_string_end):
3793 Fix calculation of the object to scan. Fixes an error when using
3794 arrow keys.
3795 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
3796 base_level_stop; instead, set base_level_stop to BEGV.
3797 Fixes crashes in vertical-motion.
3798 (next_element_from_buffer): Improve commentary for when
3799 the iterator is before prev_stop.
3800 (init_iterator): Initialize bidi_p from the default value of
3801 bidi-display-reordering, not from buffer-local value. Use the
3802 buffer-local value only if initializing for buffer iteration.
3803 (handle_invisible_prop): Support invisible properties on strings
3804 that are being bidi-reordered.
3805 (set_iterator_to_next): Support bidi reordering of C strings and
3806 Lisp strings.
3807 (next_element_from_string): Support bidi reordering of Lisp
3808 strings.
3809 (handle_stop_backwards): Support Lisp strings as well.
3810 (display_string): Support display of R2L glyph rows.
3811 Use IT_STRING_CHARPOS when displaying from a Lisp string.
3812 (init_iterator): Don't initialize it->bidi_p for strings
3813 here.
3814 (reseat_to_string): Initialize it->bidi_p for strings here.
3815 (next_element_from_string, next_element_from_c_string)
3816 (next_element_from_buffer): Add xassert's for correspondence
3817 between IT's object being iterated and it->bidi_it.string
3818 structure.
3819 (face_before_or_after_it_pos): Support bidi iteration.
3820 (next_element_from_c_string): Handle the case of the first string
3821 character that is not the first one in the visual order.
3822 (get_visually_first_element): New function, refactored from common
3823 parts of next_element_from_buffer, next_element_from_string, and
3824 next_element_from_c_string.

3864 iterator.

3883 (move_it_in_display_line_to): If iterator ended up at
3884 EOL, but we never saw any buffer positions smaller than
3885 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
3886 motion in bidi-reordered lines.
3887 (move_it_in_display_line_to): Record prev_method and prev_pos
3888 immediately before the call to set_iterator_to_next. Fixes cursor

4277 (clone_per_buffer_values): Don't assume that

4282 New macros, used in the buffer.c change.

4316 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
4317
4318 Random fixes. E.g., (random) never returned negative values.
4319 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
4320 subseconds part to the entropy, as that's a bit more random.
4321 Prefer signed to unsigned, since the signedness doesn't matter and
4322 in general we prefer signed. When given a limit, use a
4323 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
4324 latter isn't right if USE_2_TAGS_FOR_INTS.
4325 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
4326 not 0..VALMASK. Don't discard "excess" bits that random () returns.

4336 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
4337
4338 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
4339 This is more efficient than Ffile_directory_p and avoids a minor race.
4340
4341 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
4342
4343 * buffer.c (Foverlay_put): Say what the return value is
4344 (bug#7835).
4345

4364 (syms_of_gnutls): Remove duplicate DEFSYM for
4365 Qgnutls_bootprop_verify_hostname_error, an error for
4366 Qgnutls_bootprop_verify_error (which is no longer used).
4367
4368 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
4369 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
4370 Also (re)move comments that are misplaced or no longer relevant.
4371

4426 (Fcopy_keymap): Handle embedded parents.
4427 (Fcommand_remapping, define_as_prefix): Simplify.

4470
4471 * eval.c (struct backtrace): Simplify and port the data structure.
4472 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
4473 signed bit field, as this assumption is not portable and it makes
4474 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
4475 "char debug_on_exit : 1" as this is not portable either; instead,
4476 use the portable "unsigned int debug_on_exit : 1". Remove unused
4477 member evalargs. Remove obsolete comments about cc bombing out.
4478
4479 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

4523
4524 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.

4649 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
4650 for sizes. Check for string overflow more accurately.
4651 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
4652
4653 * macros.c: Integer and buffer overflow fixes.
4654 * keyboard.h (struct keyboard.kbd_macro_bufsize):
4655 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
4656 Use ptrdiff_t, not int, for sizes.
4657 Don't increment bufsize until after realloc succeeds.
4658 Check for size-calculation overflow.
4659 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
4660
4661 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
4662
4663 * lread.c: Integer overflow fixes.
4664 (read_integer): Radix is now EMACS_INT, not int,
4665 to improve quality of diagnostics for out-of-range radices.
4666 Calculate buffer size correctly for out-of-range radices.
4667 (read1): Check for integer overflow in radices, and in
4668 read-circle numbers.
4669 (read_escape): Avoid int overflow.
4670 (Fload, openp, read_buffer_size, read1)
4671 (substitute_object_recurse, read_vector, read_list, map_obarray):
4672 Use ptrdiff_t, not int, for sizes.
4673 (read1): Use EMACS_INT, not int, for sizes.
4674 Check for size overflow.
4675
4676 * image.c (cache_image): Check for size arithmetic overflow.
4677
4678 * lread.c: Integer overflow issues.
4679 (saved_doc_string_size, saved_doc_string_length)
4680 (prev_saved_doc_string_size, prev_saved_doc_string_length):
4681 Now ptrdiff_t, not int.
4682 (read1): Don't assume doc string length fits in int. Check for
4683 out-of-range doc string lengths.

4686
4687 2011-06-22 Leo Liu <sdl.web@gmail.com>
4688
4689 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
4690 Move to minibuffer.el.
4691
4692 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
4693
4694 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
4695 The following patches are for when GLYPH_DEBUG && !XASSERT.
4696 * dispextern.h (trace_redisplay_p, dump_glyph_string):
4697 * dispnew.c (flush_stdout):
4698 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
4699 Mark as externally visible.
4700 * dispnew.c (check_window_matrix_pointers): Now static.
4701 * dispnew.c (window_to_frame_vpos):
4702 * xfns.c (unwind_create_frame):
4703 * xterm.c (x_check_font): Remove unused local.
4704 * scroll.c (CHECK_BOUNDS):
4705 * xfaces.c (cache_fache): Rename local to avoid shadowing.
4706 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
4707 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
4708 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
4709 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
4710 Now static.
4711 (debug_method_add): Use va_list and vsprintf rather than relying
4712 on undefined behavior with wrong number of arguments.
4713 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
4714 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
4715 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
4716 since we're not interested in debugging glyphs with old libraries.
4717 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
4718 GCC 4.6.0's static checking.
4719
4720 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
4721
4722 Integer overflow and signedness fixes (Bug#8873).

4731 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
4732 (x_create_bitmap_from_xpm_data):
4733 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
4734 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
4735 (.bitmaps_last):
4736 * xfaces.c (load_pixmap):
4737 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
4738 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
4739 (.bitmaps_last, struct x_output.icon_bitmap):
4740 Use ptrdiff_t, not int, for bitmap indexes.
4741 (x_allocate_bitmap_record): Check for size overflow.
4742 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
4743
4744 Use ptrdiff_t, not int, for overlay counts.
4745 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
4746 * editfns.c (overlays_around, get_pos_property):
4747 * textprop.c (get_char_property_and_overlay):
4748 * xdisp.c (next_overlay_change, note_mouse_highlight):
4749 * xfaces.c (face_at_buffer_position):
4750 * buffer.c (OVERLAY_COUNT_MAX): New macro.
4751 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
4752 (Fnext_overlay_change, Fprevious_overlay_change)
4753 (mouse_face_overlay_overlaps, Foverlays_in):
4754 Use ptrdiff_t, not int, for sizes.
4755 (overlays_at, overlays_in): Check for size-calculation overflow.
4756
4757 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
4758
4759 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
4760 (x_session_initialize): Do not assume string length fits in int.
4761
4762 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
4763 This is unlikely, but can occur if DPI is outlandish.
4764
4765 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
4766 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
4767
4768 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
4769 * xrdb.c (magic_file_p, search_magic_path):
4770 Omit last arg SUFFIX; it was always 0. All callers changed.
4771 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
4772
4773 * xfont.c (xfont_match): Avoid need for strlen.
4774
4775 * xfns.c: Don't assume strlen fits in int.
4776 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
4777
4778 * xdisp.c (message_log_check_duplicate): Return intmax_t,
4779 not unsigned long, as we prefer signed integers. All callers changed.
4780 Detect integer overflow in repeat count.
4781 (message_dolog): Don't assume print length fits in 39 bytes.
4782 (display_mode_element): Don't assume strlen fits in int.
4783
4784 * termcap.c: Don't assume sizes fit in int and never overflow.
4785 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
4786 (gobble_line): Check for size-calculation overflow.
4787
4788 * minibuf.c (Fread_buffer):
4789 * lread.c (intern, intern_c_string):
4790 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
4791 Don't assume string length fits in int.
4792
4793 * keyboard.c (parse_tool_bar_item):
4794 * gtkutil.c (style_changed_cb): Avoid need for strlen.
4795

4800 Don't assume integer property fits in fixnum.
4801 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
4802
4803 * filelock.c: Fix some buffer overrun and integer overflow issues.
4804 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
4805 Reformulate so as not to need the command string.
4806 Invoke gzip -cd rather than gunzip, as it's more portable.
4807 (lock_info_type, lock_file_1, lock_file):
4808 Don't assume pid_t and time_t fit in unsigned long.
4809 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
4810 (current_lock_owner): Prefer signed type for sizes.
4811 Use memcpy, not strncpy, where memcpy is what is really wanted.
4812 Don't assume (via atoi) that time_t and pid_t fit in int.
4813 Check for time_t and/or pid_t out of range, e.g., via a network share.
4814 Don't alloca where an auto var works fine.
4815
4816 * fileio.c: Fix some integer overflow issues.
4817 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
4818 Don't assume string length fits in int.
4819 (directory_file_name): Don't assume string length fits in long.
4820 (make_temp_name): Don't assume pid fits in int, or that its print
4821 length is less than 20.
4822
4823 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
4824
4825 * coding.c (make_subsidiaries): Don't assume string length fits in int.
4826
4827 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
4828
4829 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
4830 We prefer signed integers, even for size calculations.
4831
4832 * emacs.c: Don't assume string length fits in 'int'.
4833 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
4834 (main): Don't invoke strlen when not needed.
4835
4836 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
4837 (XD_DEBUG_MESSAGE): Don't waste a byte.
4838
4839 * callproc.c (getenv_internal_1, getenv_internal)
4840 (Fgetenv_internal):
4841 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
4842
4843 * lread.c (invalid_syntax): Omit length argument.
4844 All uses changed. This doesn't fix a bug, but it simplifies the
4845 code away from its former Hollerith-constant appearance, and it's
4846 one less 'int' to worry about when looking at integer-overflow issues.
4847 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
4848
4849 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
4850 This didn't break anything, but it didn't help either.
4851 It's confusing to put a bogus integer in a place where the actual
4852 value does not matter.
4853 (LIST_END_P): Remove unused macro and its bogus comment.
4854 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
4855
4856 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
4857 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
4858 implementation.
4859 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
4860 We prefer signed types, and the value cannot exceed the EMACS_INT
4861 range anyway (because otherwise the length would not be representable).
4862 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
4863 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
4864 This avoids a GCC warning when WIDE_EMACS_INT.
4865
4866 * indent.c (sane_tab_width): New function.
4867 (current_column, scan_for_column, Findent_to, position_indentation)
4868 (compute_motion): Use it. This is just for clarity.
4869 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
4870
4871 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
4872
4873 * lisp.h (lint_assume): New macro.
4874 * composite.c (composition_gstring_put_cache):
4875 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
4876
4877 * editfns.c, insdel.c:
4878 Omit unnecessary forward decls, to simplify future changes.
4879
4880 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
4881
4882 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
4883
4884 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
4885 Use much-faster test for byte-length change.
4886 Don't assume string byte-length fits in 'int'.
4887 Check that character arg fits in 'int'.
4888 (mapcar1): Declare byte as byte, for clarity.
4889
4890 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
4891
4892 * fns.c (concat): Catch string overflow earlier.
4893 Do not rely on integer wraparound.
4894
4895 * dispextern.h (struct it.overlay_strings_charpos)
4896 (struct it.selective): Now EMACS_INT, not int.
4897 * xdisp.c (forward_to_next_line_start)
4898 (back_to_previous_visible_line_start)
4899 (reseat_at_next_visible_line_start, next_element_from_buffer):
4900 Don't arbitrarily truncate the value of 'selective' to int.
4901
4902 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
4903
4904 * composite.c: Don't truncate sizes to 'int'.
4905 (composition_gstring_p, composition_reseat_it)
4906 (composition_adjust_point): Use EMACS_INT, not int.
4907 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
4908 not EMACS_UINT, for indexes.
4909
4910 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
4911
4912 * buffer.c: Include <verify.h>.
4913 (struct sortvec.priority, struct sortstr.priority):
4914 Now EMACS_INT, not int.
4915 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
4916 (struct sortstr.size, record_overlay_string)
4917 (struct sortstrlist.size, struct sortlist.used):
4918 Don't truncate size to int.
4919 (record_overlay_string): Check for size-calculation overflow.
4920 (init_buffer_once): Check at compile-time, not run-time.
4921
4922 2011-06-22 Jim Meyering <meyering@redhat.com>
4923
4924 Don't leak an XBM-image-sized buffer
4925 * image.c (xbm_load): Free the image buffer after using it.
4926
4927 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
4928
4929 Port to Sun C.
4930 * composite.c (find_automatic_composition): Omit needless 'return 0;'
4931 that Sun C diagnosed.
4932 * fns.c (secure_hash): Fix pointer signedness issue.
4933 * intervals.c (static_offset_intervals): New function.
4934 (offset_intervals): Use it.
4935
4936 2011-06-21 Leo Liu <sdl.web@gmail.com>
4937
4938 * deps.mk (fns.o):
4939 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
4940 sha512.h.
4941
4942 * fns.c (secure_hash): Rename from crypto_hash_function and change
4943 the first arg to accept symbols.
4944 (Fsecure_hash): New primitive.
4945 (syms_of_fns): New symbols.
4946
4947 2011-06-20 Deniz Dogan <deniz@dogan.se>
4948
4949 * process.c (Fset_process_buffer): Clarify return value in
4950 docstring.
4951
4952 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
4953
4954 * dispnew.c (add_window_display_history): Use BVAR.
4955
4956 * xdisp.c (debug_method_add): Use BVAR.
4957 (check_window_end, dump_glyph_matrix, dump_glyph)
4958 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
4959
4960 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
4961 Likewise.
4962
4963 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
4964 check till after the cache is created in init_frame_faces.
4965
4966 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
4967
4968 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
4969
4970 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
4971
4972 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
4973 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
4974 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
4975
4976 Improve buffer-overflow checking (Bug#8873).
4977 * fileio.c (Finsert_file_contents):
4978 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
4979 Remove the old (too-loose) buffer overflow checks.
4980 They weren't needed, since make_gap checks for buffer overflow.
4981 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
4982 The old code merely checked for Emacs fixnum overflow, and relied
4983 on undefined (wraparound) behavior. The new code avoids undefined
4984 behavior, and also checks for ptrdiff_t and/or size_t overflow.
4985
4986 * editfns.c (Finsert_char): Don't dump core with very negative counts.
4987 Tune. Don't use wider integers than needed. Don't use alloca.
4988 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
4989
4990 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
4991
4992 * insdel.c, lisp.h (buffer_overflow): New function.
4993 (insert_from_buffer_1, replace_range, replace_range_2):
4994 * insdel.c (make_gap_larger):
4995 * editfns.c (Finsert_char):
4996 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
4997
4998 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
4999
5000 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
5001
5002 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
5003
5004 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
5005 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
5006
5007 * fileio.c: Don't assume EMACS_INT fits in off_t.
5008 (emacs_lseek): New static function.
5009 (Finsert_file_contents, Fwrite_region): Use it.
5010 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
5011
5012 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
5013
5014 * fns.c: Don't overflow int when computing a list length.
5015 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
5016 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
5017 truncation on 64-bit hosts. Check for QUIT every
5018 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
5019 faster and is responsive enough.
5020 (Flength): Report an error instead of overflowing an integer.
5021 (Fsafe_length): Return a float if the value is not representable
5022 as a fixnum. This shouldn't happen except in contrived situations.
5023 (Fnthcdr, Fsort): Don't assume list length fits in int.
5024 (Fcopy_sequence): Don't assume vector length fits in int.
5025
5026 * alloc.c: Check that resized vectors' lengths fit in fixnums.
5027 (header_size, word_size): New constants.
5028 (allocate_vectorlike): Don't check size overflow here.
5029 (allocate_vector): Check it here instead, since this is the only
5030 caller of allocate_vectorlike that could cause overflow.
5031 Check that the new vector's length is representable as a fixnum.
5032
5033 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
5034 The previous code was bogus. For example, next_almost_prime (32)
5035 returned 39, which is undesirable as it is a multiple of 3; and
5036 next_almost_prime (24) returned 25, which is a multiple of 5 so
5037 why was the code bothering to check for multiples of 7?
5038
5039 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
5040
5041 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
5042
5043 Variadic C functions now count arguments with ptrdiff_t.
5044 This partly undoes my 2011-03-30 change, which replaced int with size_t.
5045 Back then I didn't know that the Emacs coding style prefers signed int.
5046 Also, in the meantime I found a few more instances where arguments
5047 were being counted with int, which may truncate counts on 64-bit
5048 machines, or EMACS_INT, which may be unnecessarily wide.
5049 * lisp.h (struct Lisp_Subr.function.aMANY)
5050 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
5051 Arg counts are now ptrdiff_t, not size_t.
5052 All variadic functions and their callers changed accordingly.
5053 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
5054 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
5055 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
5056 * callint.c (Fcall_interactively): Check arg count for overflow,
5057 to avoid potential buffer overrun. Use signed char, not 'int',
5058 for 'varies' array, so that we needn't bother to check its size
5059 calculation for overflow.
5060 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
5061 * eval.c (apply_lambda):
5062 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
5063 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
5064 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
5065
5066 * callint.c (Fcall_interactively): Don't use index var as event count.
5067
5068 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
5069 * mem-limits.h (SIZE): Remove; no longer used.
5070
5071 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
5072
5073 Remove unnecessary casts.
5074 * xterm.c (x_term_init):
5075 * xfns.c (x_set_border_pixel):
5076 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
5077 These aren't needed now that we assume ANSI C.
5078
5079 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
5080 It's more likely to cause problems (due to unsigned overflow)
5081 than to cure them.
5082
5083 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
5084
5085 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
5086
5087 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
5088
5089 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
5090
5091 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
5092
5093 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
5094
5095 GLYPH_CODE_FACE returns EMACS_INT, not int.
5096 * dispextern.h (merge_faces):
5097 * xfaces.c (merge_faces):
5098 * xdisp.c (get_next_display_element, next_element_from_display_vector):
5099 Don't assume EMACS_INT fits in int.
5100
5101 * character.h (CHAR_VALID_P): Remove unused parameter.
5102 * fontset.c, lisp.h, xdisp.c: All uses changed.
5103
5104 * editfns.c (Ftranslate_region_internal): Omit redundant test.
5105
5106 * fns.c (concat): Minor tuning based on overflow analysis.
5107 This doesn't fix any bugs. Use int to hold character, instead
5108 of constantly refetching from Emacs object. Use XFASTINT, not
5109 XINT, for value known to be a character. Don't bother comparing
5110 a single byte to 0400, as it's always less.
5111
5112 * floatfns.c (Fexpt):
5113 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
5114
5115 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
5116 for characters.
5117
5118 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
5119
5120 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
5121 Without this fix, on a 64-bit host (aset S 0 4294967386) would
5122 incorrectly succeed when S was a string, because 4294967386 was
5123 truncated before it was used.
5124
5125 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
5126 Otherwise, an out-of-range integer could cause undefined behavior
5127 on a 64-bit host.
5128
5129 * composite.c: Use int, not EMACS_INT, for characters.
5130 (fill_gstring_body, composition_compute_stop_pos): Use int, not
5131 EMACS_INT, for values that are known to be in character range.
5132 This doesn't fix any bugs but is the usual style inside Emacs and
5133 may generate better code on 32-bit machines.
5134
5135 Make sure a 64-bit char is never passed to ENCODE_CHAR.
5136 This is for reasons similar to the recent CHAR_STRING fix.
5137 * charset.c (Fencode_char): Check that character arg is actually
5138 a character. Pass an int to ENCODE_CHAR.
5139 * charset.h (ENCODE_CHAR): Verify that the character argument is no
5140 wider than 'int', as a compile-time check to prevent future regressions
5141 in this area.
5142
5143 * character.c (char_string): Remove unnecessary casts.
5144
5145 Make sure a 64-bit char is never passed to CHAR_STRING.
5146 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
5147 by silently ignoring the top 32 bits, allowing some values
5148 that were far too large to be valid characters.
5149 * character.h: Include <verify.h>.
5150 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
5151 arguments are no wider than unsigned, as a compile-time check
5152 to prevent future regressions in this area.
5153 * data.c (Faset):
5154 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
5155 (Fsubst_char_in_region):
5156 * fns.c (concat):
5157 * xdisp.c (decode_mode_spec_coding):
5158 Adjust to CHAR_STRING's new requirement.
5159 * editfns.c (Finsert_char, Fsubst_char_in_region):
5160 * fns.c (concat): Check that character args are actually
5161 characters. Without this test, these functions did the wrong
5162 thing with wildly out-of-range values on 64-bit hosts.
5163
5164 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
5165 These casts should not be needed on 32-bit hosts, either.
5166 * keyboard.c (read_char):
5167 * lread.c (Fload): Remove casts to unsigned.
5168
5169 * lisp.h (UNSIGNED_CMP): New macro.
5170 This fixes comparison bugs on 64-bit hosts.
5171 (ASCII_CHAR_P): Use it.
5172 * casefiddle.c (casify_object):
5173 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
5174 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
5175 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
5176 * dispextern.h (FACE_FROM_ID):
5177 * keyboard.c (read_char): Use UNSIGNED_CMP.
5178
5179 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
5180 not to EMACS_INT, to avoid GCC warning.
5181
5182 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
5183
5184 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
5185 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
5186 isn't needed on 32-bit machines.
5187
5188 * buffer.c (Fgenerate_new_buffer_name):
5189 Use EMACS_INT for count, not int.
5190 (advance_to_char_boundary): Return EMACS_INT, not int.
5191
5192 * data.c (Qcompiled_function): Now static.
5193
5194 * window.c (window_body_lines): Now static.
5195
5196 * image.c (gif_load): Rename local to avoid shadowing.
5197
5198 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
5199 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
5200 * alloc.c (make_save_value): Integer argument is now of type
5201 ptrdiff_t, not int.
5202 (mark_object): Use ptrdiff_t, not int.
5203 * lisp.h (pD): New macro.
5204 * print.c (print_object): Use it.
5205
5206 * alloc.c: Use EMACS_INT, not int, to count objects.
5207 (total_conses, total_markers, total_symbols, total_vector_size)
5208 (total_free_conses, total_free_markers, total_free_symbols)
5209 (total_free_floats, total_floats, total_free_intervals)
5210 (total_intervals, total_strings, total_free_strings):
5211 Now EMACS_INT, not int. All uses changed.
5212 (Fgarbage_collect): Compute overall total using a double, so that
5213 integer overflow is less likely to be a problem. Check for overflow
5214 when converting back to an integer.
5215 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
5216 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
5217 These were 'int' variables that could overflow on 64-bit hosts;
5218 they were never used, so remove them instead of repairing them.
5219 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
5220 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
5221 Previously, this ceilinged at INT_MAX, but that doesn't work on
5222 64-bit machines.
5223 (allocate_pseudovector): Don't use EMACS_INT when int would do.
5224
5225 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
5226 (allocate_vectorlike): Check for ptrdiff_t overflow.
5227 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
5228 when a (possibly-narrower) signed value would do just as well.
5229 We prefer using signed arithmetic, to avoid comparison confusion.
5230
5231 * alloc.c: Catch some string size overflows that we were missing.
5232 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
5233 for convenience in STRING_BYTES_MAX.
5234 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
5235 The definition here is exact; the one in lisp.h was approximate.
5236 (allocate_string_data): Check for string overflow. This catches
5237 some instances we weren't catching before. Also, it catches
5238 size_t overflow on (unusual) hosts where SIZE_MAX <= min
5239 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
5240 and ptrdiff_t and EMACS_INT are both 64 bits.
5241
5242 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
5243 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
5244 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
5245
5246 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
5247
5248 * alloc.c (Fmake_string): Check for out-of-range init.
5249
5250 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
5251
5252 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
5253
5254 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
5255
5256 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
5257 xg_get_default_scrollbar_width.
5258
5259 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
5260 (int_gtk_range_get_value): Move to the scroll bar part of the file.
5261 (style_changed_cb): Call update_theme_scrollbar_width and call
5262 x_set_scroll_bar_default_width and xg_frame_set_char_size for
5263 all frames (Bug#8505).
5264 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
5265 Call gtk_window_set_resizable if HAVE_GTK3.

5267 and height if HAVE_GTK3 (Bug#8505).
5268 (scroll_bar_width_for_theme): New variable.
5269 (update_theme_scrollbar_width): New function.
5270 (xg_get_default_scrollbar_width): Move code to
5271 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
5272 (xg_initialize): Call update_theme_scrollbar_width.
5273
5274 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
5275
5276 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
5277
5278 2011-06-12 Martin Rudalics <rudalics@gmx.at>
5279
5280 * frame.c (make_frame): Call other_buffer_safely instead of
5281 other_buffer.
5282
5283 * window.c (temp_output_buffer_show): Call display_buffer with
5284 second argument Vtemp_buffer_show_specifiers and reset latter
5285 immediately after the call.
5286 (Vtemp_buffer_show_specifiers): New variable.
5287 (auto_window_vscroll_p, next_screen_context_lines)
5288 (Vscroll_preserve_screen_position): Remove leading asterisks from
5289 doc-strings.
5290
5291 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
5292
5293 Fix minor problems found by GCC 4.6.0 static checking.

5300 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
5301 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
5302 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
5303 if HAVE_GPM.
5304 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
5305 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
5306 Define only if HAVE_GPM.
5307 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
5308 (update_hints_inhibit): Remove; never set. All uses removed.
5309 * widgetprv.h (emacsFrameClassRec): Remove decl.
5310 * window.c (delete_deletable_window): Now returns void, since it
5311 wasn't returning anything.
5312 (compare_window_configurations): Remove unused locals.
5313 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
5314 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.

5316 the same widths as pointers. This follows up on the 2011-05-06 patch.
5317 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
5318 * xterm.h: Likewise.
5319 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
5320
5321 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
5322
5323 * makefile.w32-in: Update dependencies.

5335 consequently deletable windows.
5336 (window_tree, Fwindow_tree): Remove. Supply functionality in
5337 window.el.
5338 (compare_window_configurations): Simplify code.
5339

5341
5342 * image.c (imagemagick_load_image): Fix type mismatch.
5343 (Fimagemagick_types): Likewise.
5344

5358 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
5359 calls to replace_buffer_in_windows and
5360 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
5361 if allowed.
5362 (record_buffer): Inhibit quitting and rewrite using quittable
5363 functions. Run Qbuffer_list_update_hook if allowed.
5364 (Frecord_buffer, Funrecord_buffer): New functions.

5381 (Fother_window): Move to window.el.
5382 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
5383 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.

5460 (delete_deletable_window, resize_root_window)
5461 (resize_frame_windows): Declare prototypes.
5462
5463 * window.c (resize_window_apply): Make definition be "static" to

5812 display string.
5813 (bidi_paragraph_init, bidi_resolve_explicit_1)
5814 (bidi_level_of_next_char): Call bidi_fetch_char and

5821 instead of using explicit *_CHAR codes.
5822 (bidi_resolve_explicit, bidi_resolve_weak):

5839 (display_prop_intangible_p): Reimplement to call
5840 handle_display_spec instead of single_display_spec_intangible_p.
5841 Accept 3 additional arguments needed by handle_display_spec.
5842 This fixes incorrect cursor motion across display property with complex
5843 values: lists, `(when COND...)' forms, etc.
5844 (single_display_spec_string_p): Support property values that are
5845 lists with the argument STRING its top-level element.
5846 (display_prop_string_p): Fix the condition for processing a
5847 property that is a list to be consistent with handle_display_spec.
5848 (handle_display_spec): New function, refactored from the
5849 last portion of handle_display_prop.
5850 (compute_display_string_pos): Accept additional argument

5852 value of a `display' property is a "replacing spec".
5853 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
5854 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

5867
5868 * dispextern.h (struct bidi_it): New member frame_window_p.
5869 (bidi_init_it): Update prototypes.
5870 (display_prop_intangible_p): Update prototype.

5884 * gnutls.c: Use Emacs's memory allocators.
5885 Without this change, the gnutls library would invoke malloc etc.
5886 directly, which causes problems on non-SYNC_INPUT hosts, and which

5888 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
5889 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
5890 xfree instead of the default malloc, realloc, free.
5891 (Fgnutls_boot): No need to check for memory allocation failure,
5892 since xmalloc does that for us.
5893
5894 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
5895 * category.c (hash_get_category_set):

5912 * lisp.h (struct Lisp_Hash_Table):
5913 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
5914 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
5915 for hashes and hash indexes, instead of 'unsigned' and 'int'.
5916 * alloc.c (allocate_vectorlike):
5917 Check for overflow in vector size calculations.
5918 * ccl.c (ccl_driver):
5919 Check for overflow when converting EMACS_INT to int.
5920 * fns.c, image.c: Remove unnecessary static decls that would otherwise
5921 need to be updated by these changes.
5922 * fns.c (make_hash_table, maybe_resize_hash_table):
5923 Check for integer overflow with large hash tables.
5924 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):

5926 (SXHASH_REDUCE): New macro.
5927 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
5928 Use it instead of discarding useful hash info with large hash values.
5929 (sxhash_float): New function.
5930 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
5931 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
5932 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
5933 Rewrite to use FIXNUM_BITS, as this simplifies things.
5934 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
5935 Adjust signatures to match updated version of code.
5936 (consing_since_gc): Now EMACS_INT, since a single hash table can
5937 use more than INT_MAX bytes.

5985
5986 Make it possible to run ./temacs.
5987
5988 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
5989 syms_of_callproc does the same thing. Remove test for
5990 "initialized", do it in the caller.
5991 * emacs.c (main): Avoid calling set_initial_environment when dumping.
5992

6028 (x_clipboard_manager_save_all): Move extern decl to ...
6029 * xterm.h: ... here, so that it can be checked for consistency.
6030
6031 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
6032

6047 2011-05-28 Jim Meyering <meyering@redhat.com>
6048
6049 Avoid a sign-extension bug in crypto_hash_function.
6050 * fns.c (to_uchar): Define.
6051 (crypto_hash_function): Use it to convert some newly-signed
6052 variables to unsigned, to avoid sign-extension bugs. For example,
6053 without this change, (md5 "truc") would evaluate to
6054 45723a2aff78ff4fff7fff1114760e62 rather than the expected
6055 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

6058 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
6059
6060 Integer overflow fixes.
6061
6062 * dbusbind.c: Serial number integer overflow fixes.
6063 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
6064 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
6065 to hold a serial number that is too large for a fixnum.
6066 (Fdbus_method_return_internal, Fdbus_method_error_internal):
6067 Check for serial numbers out of range. Decode any serial number
6068 that was so large that it became a float. (Bug#8722)
6069
6070 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
6071 (Fdbus_call_method, Fdbus_call_method_asynchronously):
6072 Use XFASTINT rather than XUINT when numbers are nonnegative.
6073 (xd_append_arg, Fdbus_method_return_internal):
6074 (Fdbus_method_error_internal): Likewise. Also, for unsigned
6075 arguments, check that Lisp number is nonnegative, rather than
6076 silently wrapping negative numbers around. (Bug#8722)
6077 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
6078 (Bug#8722)
6079
6080 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
6081
6082 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
6083
6084 ccl: Add integer overflow checks.
6085 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
6086 (IN_INT_RANGE): New macros.
6087 (ccl_driver): Use them to check for integer overflow when
6088 decoding a CCL program. Many of the new checks are whether XINT (x)
6089 fits in int; it doesn't always, on 64-bit hosts. The new version
6090 doesn't catch all possible integer overflows, but it's an
6091 improvement. (Bug#8719)
6092
6093 * alloc.c (make_event_array): Use XINT, not XUINT.
6094 There's no need for unsigned here.
6095
6096 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
6097 This follows up to the 2011-05-06 change that substituted uintptr_t
6098 for EMACS_INT. This case wasn't caught back then.
6099
6100 Rework Fformat to avoid integer overflow issues.
6101 * editfns.c: Include <float.h> unconditionally, as it's everywhere
6102 now (part of C89). Include <verify.h>.
6103 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
6104 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
6105 (Fformat): Avoid the prepass trying to compute sizes; it was only
6106 approximate and thus did not catch overflow reliably. Instead, walk
6107 through the format just once, formatting and computing sizes as we go,
6108 checking for integer overflow at every step, and allocating a larger
6109 buffer as needed. Keep track separately whether the format is
6110 multibyte. Keep only the most-recently calculated precision, rather
6111 than them all. Record whether each argument has been converted to
6112 string. Use EMACS_INT, not int, for byte and char and arg counts.
6113 Support field widths and precisions larger than INT_MAX. Avoid
6114 sprintf's undefined behavior with conversion specifications such as %#d
6115 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
6116 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
6117 formatting out-of-range floating point numbers with int
6118 formats. (Bug#8668)
6119
6120 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
6121
6122 * data.c: Avoid integer truncation in expressions involving floats.
6123 * data.c: Include <intprops.h>.
6124 (arith_driver): When there's an integer overflow in an expression
6125 involving floating point, convert the integers to floating point
6126 so that the resulting value does not suffer from catastrophic
6127 integer truncation. For example, on a 64-bit host (* 4
6128 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
6129 Do not rely on undefined behavior after integer overflow.
6130
6131 merge count_size_as_multibyte, parse_str_to_multibyte
6132 * character.c, character.h (count_size_as_multibyte):
6133 Rename from parse_str_to_multibyte; all uses changed.
6134 Check for integer overflow.
6135 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
6136 since it's now a duplicate of the other. This is more of
6137 a character than a buffer op, so better that it's in character.c.
6138 * fns.c, print.c: Adjust to above changes.
6139
6140 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
6141
6142 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
6143
6144 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
6145
6146 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
6147 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
6148 (x_clipboard_manager_save): Now static.
6149 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
6150
6151 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
6152 (crypto_hash_function): Now static.
6153 Fix pointer signedness problems. Avoid unnecessary initializations.
6154
6155 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
6156

6158
6159 * terminal.c (create_terminal): Initialize it.
6160
6161 * xselect.c: Support for clipboard managers.
6162 (Vselection_alist): Move to termhooks.h as terminal-local var.
6163 (LOCAL_SELECTION): New macro.
6164 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
6165 (symbol_to_x_atom): Remove gratuitous arg.
6166 (x_handle_selection_request, lisp_data_to_selection_data)
6167 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
6168 (x_own_selection, x_get_local_selection, x_convert_selection):
6169 New arg, specifying work frame. Use terminal-local Vselection_alist.
6170 (some_frame_on_display): Delete unused function.
6171 (Fx_own_selection_internal, Fx_get_selection_internal)
6172 (Fx_disown_selection_internal, Fx_selection_owner_p)
6173 (Fx_selection_exists_p): New optional frame arg.
6174 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
6175 (x_handle_selection_clear): Don't treat other terminals with the
6176 same keyboard specially. Use the terminal-local Vselection_alist.
6177 (x_clear_frame_selections): Use Frun_hook_with_args.
6178
6179 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
6180
6181 * xterm.h: Add support for those atoms.
6182
6183 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
6184
6185 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
6186 (converted_selections, conversion_fail_tag): New global variables.
6187 (x_selection_request_lisp_error): Free the above.
6188 (x_get_local_selection): Remove unnecessary code.
6189 (x_reply_selection_request): Args changed; handle arbitrary array
6190 of converted selections stored in converted_selections.
6191 Separate the XChangeProperty and SelectionNotify steps.
6192 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
6193 (x_convert_selection): New function.
6194 (x_handle_selection_event): Simplify.
6195 (x_get_foreign_selection): Don't ignore incoming requests while
6196 waiting for an answer; this will fail when we implement
6197 SAVE_TARGETS, and seems unnecessary anyway.
6198 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
6199 (Vx_sent_selection_functions): Doc fix.
6200
6201 2011-05-26 Leo Liu <sdl.web@gmail.com>

6240 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
6241 Remove macros that are defined and never used.
6242 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).

6265
6266 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
6267 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
6268 and add some more files.
6269
6270 2011-05-20 Eli Zaretskii <eliz@gnu.org>
6271
6272 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
6273 report_file_error introduced by the change from 2011-05-07.
6274
6275 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
6276
6277 * systime.h (Time): Define only if emacs is defined.
6278 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
6279 where the include path doesn't have X11/X.h by default. See

6297 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
6298 (lisp): Set the order to that of loadup.el.
6299 (shortlisp): Make it a copy of $lisp.
6300 (SOME_MACHINE_LISP): Remove.
6301 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
6302 Use just $shortlisp, not $SOME_MACHINE_LISP too.
6303
6304 2011-05-18 Kenichi Handa <handa@m17n.org>
6305
6306 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
6307 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
6308 (find_automatic_composition): Mostly rewrite for efficiency.
6309
6310 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
6311
6312 * makefile.w32-in: Update dependencies.
6313
6314 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
6315
6316 * menu.c: Include limits.h (fixes the MS-Windows build broken by
6317 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
6318
6319 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
6320
6321 Fix some integer overflow issues, such as string length overflow.
6322
6323 * insdel.c (count_size_as_multibyte): Check for string overflow.
6324
6325 * character.c (lisp_string_width): Check for string overflow.
6326 Use EMACS_INT, not int, for string indexes and lengths; in
6327 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
6328 the resulting string length overflows an EMACS_INT; instead,
6329 report a string overflow if no precision given. When checking for
6330 precision exhaustion, use a check that cannot possibly have
6331 integer overflow. (Bug#8675)
6332 * character.h (lisp_string_width): Adjust to new signature.
6333
6334 * alloc.c (string_overflow): New function.
6335 (Fmake_string): Use it. This doesn't change behavior, but saves
6336 a few bytes and will simplify future changes.
6337 * character.c (string_escape_byte8): Likewise.
6338 * lisp.h (string_overflow): New decl.
6339
6340 Fixups, following up to the user-interface timestamp change.
6341 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
6342 for UI timestamps, instead of unsigned long.
6343 * msdos.c (mouse_get_pos): Likewise.
6344 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
6345 * w32gui.h (Time): Define by including "systime.h" rather than by
6346 declaring it ourselves. (Bug#8664)
6347
6348 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
6349 * image.c (clear_image_cache): Likewise.
6350
6351 * term.c (term_mouse_position): Don't assume time_t wraparound.
6352
6353 Be more systematic about user-interface timestamps.
6354 Before, the code sometimes used 'Time', sometimes 'unsigned long',
6355 and sometimes 'EMACS_UINT', to represent these timestamps.
6356 This change causes it to use 'Time' uniformly, as that's what X uses.
6357 This makes the code easier to follow, and makes it easier to catch
6358 integer overflow bugs such as Bug#8664.
6359 * frame.c (Fmouse_position, Fmouse_pixel_position):
6360 Use Time, not unsigned long, for user-interface timestamps.
6361 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
6362 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
6363 * keyboard.h (last_event_timestamp): Likewise.
6364 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
6365 * menu.h (xmenu_show): Likewise.
6366 * term.c (term_mouse_position): Likewise.
6367 * termhooks.h (struct input_event.timestamp): Likewise.
6368 (struct terminal.mouse_position_hook): Likewise.
6369 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
6370 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
6371 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
6372 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
6373 what it was before.
6374 * menu.h, termhooks.h: Include "systime.h", for Time.
6375
6376 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
6377 Don't assume that the difference between two unsigned long values
6378 can fit into an integer. At this point, we know button_down_time
6379 <= event->timestamp, so the difference must be nonnegative, so
6380 there's no need to cast the result if double-click-time is
6381 nonnegative, as it should be; check that it's nonnegative, just in
6382 case. This bug is triggered when events are more than 2**31 ms
6383 apart (about 25 days). (Bug#8664)
6384
6385 * xselect.c (last_event_timestamp): Remove duplicate decl.
6386 (x_own_selection): Remove needless cast to unsigned long.
6387
6388 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
6389 that always fit in int. Use a sentinel instead of a counter, to
6390 avoid a temp and to allay GCC's concerns about possible int overflow.
6391 * frame.h (struct frame): Use int for menu_bar_items_used
6392 instead of EMACS_INT, since it always fits in int.
6393
6394 * menu.c (grow_menu_items): Check for int overflow.
6395
6396 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
6397
6398 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
6399 Before, the code was not consistent. These values cannot exceed
6400 2**31 - 1 so there's no need to make them unsigned.
6401 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
6402 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
6403 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
6404 as modifiers.
6405 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
6406
6407 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
6408 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
6409 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
6410 presumably because the widths might not match.
6411
6412 * window.c (size_window): Avoid needless test at loop start.
6413
6414 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
6415
6416 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
6417
6418 2011-05-12 Drew Adams <drew.adams@oracle.com>
6419
6420 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
6421
6422 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6423
6424 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
6425 `width' to `bar_area_x' and `bar_area_width', respectively.
6426 (x_scroll_run): Take account of fringe background extension.
6427
6428 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
6429 Rename local vars `left' and `width' to `bar_area_x' and
6430 `bar_area_width', respectively.
6431 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
6432 background extension.
6433
6434 2011-05-10 Jim Meyering <meyering@redhat.com>
6435
6436 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
6437
6438 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
6439
6440 * image.c (Finit_image_library): Return t for built-in image types,
6441 like pbm and xbm. (Bug#8640)
6442
6443 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
6444
6445 * w32menu.c (set_frame_menubar): Fix submenu allocation.
6446
6447 2011-05-07 Eli Zaretskii <eliz@gnu.org>
6448
6449 * w32console.c (Fset_screen_color): Doc fix.
6450 (Fget_screen_color): New function.
6451 (syms_of_ntterm): Defsubr it.
6452
6453 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
6454 unlink the temporary file if Fcall_process didn't create it in the
6455 first place.
6456 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
6457 child process will be redirected to a file specified with `:file'.
6458 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
6459 cue to call_process_cleanup not to close that handle.
6460
6461 2011-05-07 Ben Key <bkey76@gmail.com>
6462
6463 * makefile.w32-in: The bootstrap-temacs rule now makes use of
6464 one of two shell specific rules, either bootstrap-temacs-CMD or
6465 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
6466 to the previous implementation of the bootstrap-temacs rule.
6467 The bootstrap-temacs-CMD rule is similar to the previous
6468 implementation of the bootstrap-temacs rule except that it
6469 makes use of the ESC_CFLAGS variable instead of the CFLAGS
6470 variable.
6471
6472 These changes, along with some changes to nt/configure.bat,
6473 nt/gmake.defs, and nt/nmake.defs, are required to extend my
6474 earlier fix to add support for --cflags and --ldflags options
6475 that include quotes so that it works whether make uses cmd or
6476 sh as the shell.
6477
6478 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
6479
6480 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
6481 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
6482 is a constant.
6483 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
6484 a string. Handle both cases.
6485 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
6486 (Fdbus_register_method): Use Qinvalid_function.
6487
6488 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6489
6490 * makefile.w32-in: Update dependencies.
6491 (LISP_H): Add inttypes.h and stdin.h.
6492 (PROCESS_H): Add unistd.h.
6493
6494 2011-05-06 Eli Zaretskii <eliz@gnu.org>
6495
6496 * lread.c: Include limits.h (fixes the MS-Windows build broken by
6497 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
6498
6499 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
6500
6501 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
6502
6503 * term.c (vfatal): Remove stray call to va_end.
6504 It's not needed and the C Standard doesn't allow it here anyway.
6505
6506 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
6507 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
6508
6509 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
6510 bytes.
6511
6512 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
6513
6514 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
6515
6516 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
6517
6518 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
6519
6520 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
6521
6522 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
6523 * charset.c (Fdefine_charset_internal): Don't initialize
6524 charset.code_space[15]. The value was garbage, on hosts with
6525 32-bit int (Bug#8600).
6526
6527 * lread.c (read_integer): Be more consistent with string-to-number.
6528 Use string_to_number to do the actual conversion; this avoids
6529 rounding errors and fixes some other screwups. Without this fix,
6530 for example, #x1fffffffffffffff was misread as -2305843009213693952.
6531 (digit_to_number): Move earlier, for benefit of read_integer.
6532 Return -1 if the digit is out of range for the base, -2 if it is
6533 not a digit in any supported base. (Bug#8602)
6534
6535 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
6536
6537 * dispnew.c (scrolling_window): Return 1 if we scrolled,
6538 to match comment at start of function. This also removes a
6539 GCC warning about overflow in a 32+64-bit port.
6540
6541 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
6542
6543 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
6544 Reported by Stefan Monnier in
6545 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
6546 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6547 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
6548
6549 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
6550 (EMACS_UINTPTR): Likewise, with uintptr_t.
6551
6552 * lisp.h: Prefer 64-bit EMACS_INT if available.
6553 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
6554 on 32-bit hosts that have 64-bit int, so that they can access
6555 large files.
6556 However, temporarily disable this change unless the temporary
6557 symbol WIDE_EMACS_INT is defined.
6558
6559 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
6560
6561 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
6562 This removes an assumption that EMACS_INT and long are the same
6563 width as pointers. The assumption is true for Emacs porting targets
6564 now, but we want to make other targets possible.
6565 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
6566 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
6567 In the rest of the code, change types of integers that hold casted
6568 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
6569 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
6570 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
6571 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
6572 No need to cast type when ORing.
6573 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
6574 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
6575 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
6576 assume EMACS_INT is the same width as char *.
6577 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
6578 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
6579 Remove no-longer-needed casts.
6580 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
6581 (xg_tool_bar_help_callback, xg_make_tool_item):
6582 Use EMACS_INTPTR to hold an integer
6583 that will be cast to void *; this can avoid a GCC warning
6584 if EMACS_INT is not the same width as void *.
6585 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
6586 * xdisp.c (display_echo_area_1, resize_mini_window_1):
6587 (current_message_1, set_message_1):
6588 Use a local to convert to proper width without a cast.
6589 * xmenu.c (dialog_selection_callback): Likewise.
6590
6591 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
6592 Also, don't assume VALBITS / RAND_BITS is less than 5,
6593 and don't rely on undefined behavior when shifting a 1 left into
6594 the sign bit.
6595 * lisp.h (get_random): Change signature to match.
6596
6597 * lread.c (hash_string): Use size_t, not int, for hash computation.
6598 Normally we prefer signed values; but hashing is special, because
6599 it's better to use unsigned division on hash table sizes so that
6600 the remainder is nonnegative. Also, size_t is the natural width
6601 for hashing into memory. The previous code used 'int', which doesn't
6602 retain enough info to hash well into very large tables.
6603 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
6604
6605 * dbusbind.c: Don't possibly lose pointer info when converting.
6606 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6607 Use XPNTR rather than XHASH, so that the high-order bits of
6608 the pointer aren't lost when converting through void *.
6609
6610 * eval.c (Fautoload): Don't double-shift a pointer.
6611
6612 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
6613
6614 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6615
6616 * gnutls.c (DEF_GNUTLS_FN):
6617 * image.c (DEF_IMGLIB_FN): Make function pointers static.
6618
6619 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
6620
6621 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
6622 marker. (Bug#8610)
6623
6624 2011-05-05 Eli Zaretskii <eliz@gnu.org>
6625
6626 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
6627 New version that can reserve upto 2GB of heap space.
6628
6629 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
6630
6631 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
6632
6633 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
6634
6635 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
6636 `gnutls_certificate_set_x509_key_file'.
6637
6638 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
6639
6640 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
6641 Update dependencies.
6642
6643 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6644
6645 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
6646 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
6647 Remove unused parameter `fildes'.
6648 * process.c (read_process_output, send_process): Don't pass it.
6649
6650 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6651
6652 Fix previous change: the library cache is defined in w32.c.
6653 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
6654 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
6655
6656 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6657
6658 Implement dynamic loading of GnuTLS on Windows.
6659
6660 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
6661 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
6662 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
6663 Declare.
6664
6665 * gnutls.c (Qgnutls_dll): Define.
6666 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
6667 (gnutls_*): Declare function pointers.
6668 (init_gnutls_functions): New function to initialize function pointers.
6669 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
6670 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
6671 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
6672 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
6673 (emacs_gnutls_write, emacs_gnutls_read)
6674 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
6675 (Fgnutls_available_p): New function.
6676 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
6677 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
6678 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
6679
6680 * image.c: Include w32.h.
6681 (Vimage_type_cache): Delete.
6682 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
6683 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
6684 (w32_delayed_load): Move to w32.c.
6685
6686 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
6687
6688 * w32.c (QCloaded_from, Vlibrary_cache): Define.
6689 (w32_delayed_load): Move from image.c. When loading a library, record
6690 its filename in the :loaded-from property of the library id.

6702
6703 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
6704 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
6705 as passed in.

6737
6738 * sysdep.c (interruptible_wait_for_termination): New function
6739 which is like wait_for_termination, but allows keyboard
6740 interruptions.
6741
6742 * callproc.c (Fcall_process): Add (:file "file") as an option for
6743 the STDOUT buffer.

6749 rather than `XVECTOR (FOO)->size'.
6750
6751 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
6752 inttypes.h, as a gnulib replacement is used if it not available in
6753 system headers.
6754

6759 of MOST_POSITIVE_FIXNUM. (Bug#8528)
6760
6761 * coding.c (coding_alloc_by_realloc): Error out if destination
6762 will grow beyond MOST_POSITIVE_FIXNUM.

6765 space for up to 2 characters produced in a loop.
6766 (decode_coding_iso_2022): Abort if there isn't enough place in

6772 aborting when %lld or %lll format is passed.
6773 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
6774 %llo or %llx format is passed. (Bug#8545)
6775
6776 * window.c (window_scroll_line_based): Use a marker instead of
6777 simple variables to record original value of point. (Bug#7952)
6778
6779 * doprnt.c (doprnt): Fix the case where a multibyte sequence
6780 produced by %s or %c overflows available buffer space. (Bug#8545)
6781
6782 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
6783
6784 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

6790
6791 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
6792
6793 * keyboard.c (Qdelayed_warnings_hook): Define.
6794 (command_loop_1): Run `delayed-warnings-hook'
6795 if Vdelayed_warnings_list is non-nil.
6796 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
6797 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
6798
6799 2011-04-28 Eli Zaretskii <eliz@gnu.org>
6800
6801 * doprnt.c (doprnt): Don't return value smaller than the buffer
6802 size if the message was truncated. (Bug#8545).
6803
6804 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
6805
6806 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
6807 (Fx_window_property): #if-0 the whole functions, not just the bodies.
6808
6809 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6810
6811 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
6812
6813 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
6814

6816
6817 2011-04-27 Eli Zaretskii <eliz@gnu.org>
6818
6819 Improve `doprnt' and its usage. (Bug#8545)
6820 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
6821 `format_end'. Remove support for %l as a conversion specifier.
6822 Don't use xrealloc. Improve diagnostics when the %l size modifier
6823 is used. Update the commentary.
6824
6825 * eval.c (verror): Simplify calculation of size_t.
6826
6827 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
6828 messages.
6829
6830 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
6831
6832 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
6833 change.
6834
6835 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6836
6837 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
6838 This makes this file independent of the recent pseudovector change.
6839
6840 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
6841
6842 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
6843
6844 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
6845 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
6846 Remove unused local.
6847 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
6848
6849 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
6850 GCC 4.6.0 optimizes based on type-based alias analysis.
6851 For example, if b is of type struct buffer * and v of type struct
6852 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
6853 != &v->size, and therefore "v->size = 1; b->size = 2; return
6854 v->size;" must therefore return 1. This assumption is incorrect
6855 for Emacs, since it type-puns struct Lisp_Vector * with many other
6856 types. To fix this problem, this patch adds a new type struct
6857 vectorlike_header that documents the constraints on layout of vectors
6858 and pseudovectors, and helps optimizing compilers not get fooled
6859 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
6860 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
6861 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
6862 the size member.
6863 (XSETPVECTYPE): Rewrite in terms of new macro.
6864 (XSETPVECTYPESIZE): New macro, specifying both type and size.
6865 This is a bit clearer, and further avoids the possibility of
6866 undesirable aliasing.
6867 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
6868 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
6869 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
6870 since Lisp_Subr is a special case (no "next" field).
6871 (ASIZE): Now uses header.size rather than size.
6872 All previous uses of XVECTOR (foo)->size replaced to use this macro,
6873 to avoid the hassle of writing XVECTOR (foo)->header.size.
6874 (struct vectorlike_header): New type.
6875 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
6876 object, to help avoid aliasing.
6877 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
6878 (SUBRP): Likewise, since Lisp_Subr is a special case.
6879 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
6880 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
6881 (struct Lisp_Hash_Table): Combine first two members into a single
6882 struct vectorlike_header member. All uses of "size" and "next" members
6883 changed to be "header.size" and "header.next".
6884 * buffer.h (struct buffer): Likewise.
6885 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
6886 * frame.h (struct frame): Likewise.
6887 * process.h (struct Lisp_Process): Likewise.
6888 * termhooks.h (struct terminal): Likewise.
6889 * window.c (struct save_window_data, struct saved_window): Likewise.
6890 * window.h (struct window): Likewise.
6891 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
6892 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
6893 * buffer.c (init_buffer_once): Likewise.
6894 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
6895 special case.
6896 * process.c (Fformat_network_address): Use local var for size,
6897 for brevity.
6898
6899 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
6900
6901 Make the Lisp reader and string-to-float more consistent (Bug#8525)
6902 * data.c (atof): Remove decl; no longer used or needed.
6903 (digit_to_number): Move to lread.c.
6904 (Fstring_to_number): Use new string_to_number function, to be
6905 consistent with how the Lisp reader treats infinities and NaNs.
6906 Do not assume that floating-point numbers represent EMACS_INT
6907 without losing information; this is not true on most 64-bit hosts.
6908 Avoid double-rounding errors, by insisting on integers when
6909 parsing non-base-10 numbers, as the documentation specifies.
6910 * lisp.h (string_to_number): New decl, replacing ...
6911 (isfloat_string): Remove.
6912 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
6913 (read1): Do not accept +. and -. as integers; this
6914 appears to have been a coding error. Similarly, do not accept
6915 strings like +-1e0 as floating point numbers. Do not report
6916 overflow for integer overflows unless the base is not 10 which
6917 means we have no simple and reliable way to continue.
6918 Break out the floating-point parsing into a new
6919 function string_to_number, so that Fstring_to_number parses
6920 floating point numbers consistently with the Lisp reader.
6921 (digit_to_number): Move here from data.c. Make it static inline.
6922 (E_CHAR, EXP_INT): Remove, replacing with ...
6923 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
6924 (string_to_number): New function, replacing isfloat_string.
6925 This function checks for valid syntax and produces the resulting
6926 Lisp float number too. Rework it so that string-to-number
6927 no longer mishandles examples like "1.0e+". Use strtoumax,
6928 so that overflow for non-base-10 numbers is reported only when
6929 there's no portable and simple way to convert to floating point.
6930
6931 * textprop.c (set_text_properties_1): Rewrite for clarity,
6932 and to avoid GCC warning about integer overflow.
6933
6934 * intervals.h (struct interval): Use EMACS_INT for members
6935 where EMACS_UINT might cause problems. See
6936 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
6937 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
6938 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
6939 All uses changed.
6940 (offset_intervals): Tell GCC not to worry about length overflow
6941 when negating a negative length.
6942
6943 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
6944 (overrun_check_free): Likewise.
6945
6946 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
6947 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
6948 word size.
6949
6950 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6951 (gnutls_make_error): Rename local to avoid shadowing.
6952 (gnutls_emacs_global_deinit): ifdef out; not used.
6953 (Fgnutls_boot): Use const for pointer to readonly storage.
6954 Comment out unused local. Fix pointer signedness problems.
6955
6956 * lread.c (openp): Don't stuff size_t into an 'int'.
6957 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
6958 about possible signed overflow.
6959
6960 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6961 (GDK_KEY_g): Don't define if already defined.
6962 (xg_prepare_tooltip): Avoid pointer signedness problem.
6963 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
6964
6965 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
6966 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
6967
6968 * xfns.c (Fx_window_property): Simplify a bit,
6969 to make a bit faster and to avoid GCC 4.6.0 warning.
6970 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
6971
6972 * fns.c (internal_equal): Don't assume size_t fits in int.
6973
6974 * alloc.c (compact_small_strings): Tighten assertion a little.
6975
6976 Replace pEd with more-general pI, and fix some printf arg casts.
6977 * lisp.h (pI): New macro, generalizing old pEd macro to other
6978 conversion specifiers. For example, use "...%"pI"d..." rather
6979 than "...%"pEd"...".
6980 (pEd): Remove. All uses replaced with similar uses of pI.
6981 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
6982 * alloc.c (check_pure_size): Don't overflow by converting size to int.
6983 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
6984 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
6985 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
6986 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
6987 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
6988 64-bit hosts.
6989 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
6990 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
6991 * print.c (safe_debug_print, print_object): Likewise.
6992 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
6993 to int.
6994 Use pI instead of if-then-else-abort. Use %p to avoid casts,
6995 avoiding the 0 flag, which is not portable.
6996 * process.c (Fmake_network_process): Use pI to avoid cast.
6997 * region-cache.c (pp_cache): Likewise.
6998 * xdisp.c (decode_mode_spec): Likewise.
6999 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
7000 behavior on 64-bit hosts with printf arg.
7001 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
7002 (x_stop_queuing_selection_requests): Likewise.
7003 (x_get_window_property): Don't truncate byte count to an 'int'
7004 when tracing.
7005
7006 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
7007 here, since it parses constructs like leading '-' and spaces,
7008 which are not wanted; and it overflows with large numbers.
7009 Instead, simply match F[0-9]+, which is what is wanted anyway.
7010
7011 * alloc.c: Remove unportable assumptions about struct layout.
7012 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
7013 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
7014 (allocate_vectorlike, make_pure_vector): Use the new macros,
7015 plus offsetof, to remove unportable assumptions about struct layout.
7016 These assumptions hold on all porting targets that I know of, but
7017 they are not guaranteed, they're easy to remove, and removing them
7018 makes further changes easier.
7019
7020 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
7021 This doesn't fix a bug but makes the code clearer.
7022 (string_overrun_cookie): Now const. Use initializers that
7023 don't formally overflow signed char, to avoid warnings.
7024 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
7025 can cause Emacs to crash when string overrun checking is enabled.
7026 (allocate_buffer): Don't assume sizeof (struct buffer) is a
7027 multiple of sizeof (EMACS_INT); it need not be, if
7028 alignof(EMACS_INT) < sizeof (EMACS_INT).
7029 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
7030
7031 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
7032
7033 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
7034
7035 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
7036
7037 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
7038 supposed to be handshaking. (Bug#8556)
7039 Reported by Paul Eggert <eggert@cs.ucla.edu>.
7040
7041 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
7042
7043 * lisp.h (Qdebug): List symbol.
7044 * eval.c (Qdebug): Restore global linkage.
7045 * keyboard.c (debug-on-event): New variable.
7046 (handle_user_signal): Break into debugger when debug-on-event
7047 matches the current signal symbol.
7048
7049 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
7050
7051 * alloc.c (check_sblock, check_string_bytes)
7052 (check_string_free_list): Convert to standard C.
7053
7054 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
7055
7056 * w32.c (emacs_gnutls_push): Fix typo.
7057
7058 2011-04-25 Eli Zaretskii <eliz@gnu.org>
7059
7060 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
7061 "cast to pointer from integer of different size".
7062
7063 Improve doprnt and its use in verror. (Bug#8545)
7064 * doprnt.c (doprnt): Document the set of format control sequences
7065 supported by the function. Use SAFE_ALLOCA instead of always
7066 using `alloca'.
7067
7068 * eval.c (verror): Don't limit the buffer size at size_max-1, that
7069 is one byte too soon. Don't use xrealloc; instead xfree and
7070 xmalloc anew.
7071
7072 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
7073
7074 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
7075 callbacks stage.
7076
7077 * gnutls.c: Renamed global_initialized to
7078 gnutls_global_initialized. Added internals for the
7079 :verify-hostname-error, :verify-error, and :verify-flags
7080 parameters of `gnutls-boot' and documented those parameters in the
7081 docstring. Start callback support.
7082 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
7083 unless a fatal error occurred. Call gnutls_alert_send_appropriate
7084 on error. Return error code.
7085 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
7086 (emacs_gnutls_read): Likewise.
7087 (Fgnutls_boot): Return handshake error code.
7088 (emacs_gnutls_handle_error): New function.
7089 (wsaerror_to_errno): Likewise.

7917 and to avoid potential problems with integer overflow.
7918 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
7919 * casetab.c (set_identity, shuffle): Likewise.
7920 * editfns.c (Fformat): Likewise.
7921 * syntax.c (skip_chars): Likewise.
7922
7923 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
7924 This also lets GCC 4.6.0 generate slightly better loop code.
7925
7926 * callint.c (Fcall_interactively): <, not <=, for optimization.
7927 (Fcall_interactively): Count the number of arguments produced,
7928 not the number of arguments given. This is simpler and lets GCC
7929 4.6.0 generate slightly better code.
7930
7931 * ftfont.c: Distingish more carefully between FcChar8 and char.
7932 The previous code passed unsigned char * to a functions like
7933 strlen and xstrcasecmp that expect char *, which does not
7934 conform to the C standard.
7935 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
7936 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
7937 char * when the C standard requires it.
7938
7939 * keyboard.c (read_char): Remove unused var.
7940
7941 * eval.c: Port to Windows vsnprintf (Bug#8435).
7942 Include <limits.h>.
7943 (SIZE_MAX): Define if the headers do not.
7944 (verror): Do not give up if vsnprintf returns a negative count.
7945 Instead, grow the buffer. This ports to Windows vsnprintf, which
7946 does not conform to C99. Problem reported by Eli Zaretskii.
7947 Also, simplify the allocation scheme, by avoiding the need for
7948 calling realloc, and removing the ALLOCATED variable.
7949
7950 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
7951
7952 Remove invocations of doprnt, as Emacs now uses vsnprintf.
7953 But keep the doprint source code for now, as we might revamp it
7954 and use it again (Bug#8435).
7955 * lisp.h (doprnt): Remove.
7956 * Makefile.in (base_obj): Remove doprnt.o.
7957 * deps.mk (doprnt.o): Remove.
7958
7959 error: Print 32- and 64-bit integers portably (Bug#8435).
7960 Without this change, on typical 64-bit hosts error ("...%d...", N)
7961 was used to print both 32- and 64-bit integers N, which relied on
7962 undefined behavior.
7963 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
7964 * lisp.h (error, verror): Mark as printf-like functions.
7965 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
7966 Report overflow in size calculations when allocating printf buffer.
7967 Do not truncate output string at its first null byte.
7968 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
7969 Truncate the output at a character boundary, since vsnprintf does not
7970 do that.
7971 * charset.c (check_iso_charset_parameter): Convert internal
7972 character to string before calling 'error', since %c now has the
7973 printf meaning.
7974 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
7975 overflow when computing char to be passed to 'error'. Do not
7976 pass Lisp_Object to 'error'; pass the integer instead.
7977 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
7978 formatted with plain %d.
7979
7980 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
7981
7982 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
7983
7984 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
7985
7986 * xterm.c (x_catch_errors): Remove duplicate declaration.
7987
7988 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
7989
7990 * xdisp.c, lisp.h (message_nolog): Remove; unused.
7991
7992 2011-04-10 Jim Meyering <meyering@redhat.com>
7993
7994 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
7995 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
7996 return ssize_t not "int", and use size_t as the buffer length.
7997 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
7998 * gnutls.h: Update declarations.
7999 * process.c (read_process_output): Use ssize_t, to match.
8000 (send_process): Likewise.
8001
8002 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
8003
8004 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
8005
8006 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
8007
8008 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
8009 Use unsigned char, to match FcChar8 type definition.
8010
8011 * xterm.c (handle_one_xevent):
8012 * xmenu.c (create_and_show_popup_menu):
8013 * xselect.c (x_decline_selection_request)
8014 (x_reply_selection_request): Avoid type-punned deref of X events.
8015
8016 2011-04-09 Eli Zaretskii <eliz@gnu.org>
8017
8018 Fix some uses of `int' instead of EMACS_INT.
8019 * search.c (string_match_1, fast_string_match)
8020 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
8021 (scan_buffer, find_next_newline_no_quit)
8022 (find_before_next_newline, search_command, Freplace_match)
8023 (Fmatch_data): Make some `int' variables be EMACS_INT.
8024
8025 * xdisp.c (display_count_lines): 3rd argument and return value now
8026 EMACS_INT. All callers changed.
8027 (pint2hrstr): Last argument is now EMACS_INT.
8028
8029 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
8030 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
8031 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
8032 (decode_coding_utf_16, decode_coding_emacs_mule)
8033 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
8034 (decode_coding_ccl, decode_coding_charset)
8035 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
8036 (decode_coding_iso_2022, decode_coding_emacs_mule)
8037 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
8038 <char_offset, last_offset>: Declare EMACS_INT.
8039 (encode_coding_utf_8, encode_coding_utf_16)
8040 (encode_coding_emacs_mule, encode_invocation_designation)
8041 (encode_designation_at_bol, encode_coding_iso_2022)
8042 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
8043 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
8044 Declare EMACS_INT.
8045 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
8046 (encode_invocation_designation): Last argument P_NCHARS is now
8047 EMACS_INT.
8048 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
8049 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
8050
8051 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
8052 All users changed.
8053
8054 * ccl.c (Fccl_execute_on_string): Declare some variables
8055 EMACS_INT.
8056
8057 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
8058
8059 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
8060

8062
8063 * process.c (Fformat_network_address): Doc fix.
8064
8065 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
8066
8067 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
8068
8069 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
8070
8071 * keyboard.c (read_char): Call Lisp function help-form-show,
8072 instead of using internal_with_output_to_temp_buffer.
8073 (Qhelp_form_show): New var.
8074 (syms_of_keyboard): Use DEFSYM macro.
8075
8076 * print.c (internal_with_output_to_temp_buffer): Function deleted.
8077
8078 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
8079
8080 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
8081
8082 * process.c (Flist_processes): Remove to Lisp.
8083 (list_processes_1): Delete.
8084
8085 2011-04-06 Eli Zaretskii <eliz@gnu.org>
8086
8087 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
8088
8089 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
8090
8091 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
8092
8093 Fix more problems found by GCC 4.6.0's static checks.
8094
8095 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
8096
8097 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
8098
8099 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
8100
8101 * xdisp.c (vmessage): Mark as a printf-like function.
8102
8103 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
8104
8105 * sound.c (sound_warning): Don't crash if arg contains a printf format.
8106
8107 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
8108 printf-like functions.
8109 (tiff_load): Add casts to remove these marks before passing them
8110 to system-supplied API.

8112 * eval.c (Fsignal): Remove excess argument to 'fatal'.
8113
8114 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
8115 This avoids several warnings with gcc -Wstrict-overflow.
8116 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
8117 directly, rather than having caller test rule sign. This avoids
8118 some unnecessary tests.
8119 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
8120 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
8121 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
8122
8123 * xfont.c (xfont_text_extents): Remove var that was set but not used.
8124 (xfont_open): Avoid unnecessary tests.
8125
8126 * composite.c (composition_gstring_put_cache): Use unsigned integer.

8132 breaking out part of COMPOSITION_DECODE_RULE.
8133 (COMPOSITION_DECODE_RULE): Use it.
8134 * composite.c (get_composition_id): Remove unused local vars,
8135 by using the new macro.
8136
8137 * textprop.c (set_text_properties_1): Change while to do-while,
8138 since the condition is always true at first.
8139
8140 * intervals.c (graft_intervals_into_buffer): Mark var as used.
8141 (interval_deletion_adjustment): Return unsigned value.
8142 All uses changed.
8143
8144 * process.c (list_processes_1, create_pty, read_process_output):
8145 (exec_sentinel): Remove vars that were set but not used.
8146 (create_pty): Remove unnecessary "volatile"s.
8147 (Fnetwork_interface_info): Avoid possibility of int overflow.
8148 (read_process_output): Do adaptive read buffering even if carryover.
8149 (read_process_output): Simplify nbytes computation if buffered.
8150
8151 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
8152
8153 * syntax.c (scan_words): Remove var that was set but not used.
8154 (update_syntax_table): Use unsigned instead of int.
8155
8156 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
8157 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
8158 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
8159
8160 * print.c (print_error_message): Avoid int overflow.
8161
8162 * font.c (font_list_entities): Redo for clarity,
8163 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
8164
8165 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
8166 (font_score): Avoid potential overflow in diff calculation.
8167
8168 * fns.c (substring_both): Remove var that is set but not used.
8169 (sxhash): Redo loop for clarity and to avoid wraparound warning.
8170
8171 * eval.c (funcall_lambda): Rename local to avoid shadowing.
8172
8173 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
8174 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
8175 can always succeed if overflow has undefined behavior.
8176
8177 * search.c (boyer_moore, wordify): Remove vars set but not used.
8178 (wordify): Omit three unnecessary tests.
8179
8180 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
8181 All callers changed. This avoids the need for an unused var.
8182
8183 * casefiddle.c (casify_region): Remove var that is set but not used.
8184
8185 * dired.c (file_name_completion): Remove var that is set but not used.
8186

8188
8189 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
8190 (Finsert_file_contents): Remove unnecessary code checking fd.
8191
8192 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
8193 Check for integer overflow on size calculations.
8194
8195 * buffer.c (Fprevious_overlay_change): Remove var that is set
8196 but not used.
8197
8198 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
8199 Remove vars that are set but not used.
8200 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
8201 (timer_check_2): Mark vars as initialized.
8202
8203 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
8204
8205 * image.c (lookup_image): Remove var that is set but not used.
8206 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
8207
8208 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
8209 that are set but not used.
8210
8211 * xfns.c (make_invisible_cursor): Don't return garbage
8212 if XCreateBitmapFromData fails (Bug#8410).
8213
8214 * xselect.c (x_get_local_selection, x_handle_property_notify):
8215 Remove vars that are set but not used.
8216
8217 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

8221 Remove var that is set but not used.
8222 (scroll_bar_windows_size): Now size_t, not int.
8223 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
8224 Check for overflow.
8225
8226 * xfaces.c (realize_named_face): Remove vars that are set but not used.
8227 (map_tty_color) [!defined MSDOS]: Likewise.
8228
8229 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
8230
8231 * coding.c: Remove vars that are set but not used.
8232 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
8233 All callers changed.
8234 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
8235 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
8236 (decode_coding_charset): Remove vars that are set but not used.

8238 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
8239 that is set but not used.

8241 * print.c (print_object): Remove var that is set but not used.
8242
8243 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
8244 The gnulib version avoids calling malloc in the usual case,
8245 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
8246 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
8247 * filelock.c (current_lock_owner): Likewise.
8248 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
8249 * sysdep.c: Include allocator.h, careadlinkat.h.
8250 (emacs_no_realloc_allocator): New static constant.
8251 (emacs_readlink): New function.
8252 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
8253 ../lib/careadlinkat.h.
8254

8256
8257 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

8261
8262 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

8270 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
8271 (fill_stretch_glyph_string): Remove parameters `row' and `area',
8272 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
8273 and thereabouts. All callers changed.
8274 (get_per_char_metric): Remove parameter `f', unused since
8275 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
8276
8277 2011-04-02 Jim Meyering <meyering@redhat.com>
8278
8279 do not dereference NULL upon failed strdup

8288
8289 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
8290 later (Bug#8403).

8336 * data.c (Finteractive_form): Handle closures.
8337
8338 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
8339 interactive spec.
8340
8341 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
8342 New byte-codes.
8343 (exec_byte_code): New function extracted from Fbyte_code to handle new
8344 calling convention for byte-code-functions. Add new byte-codes.
8345
8346 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
8347
8348 * alloc.c (Fmake_symbol): Init new `declared_special' field.
8349
8350 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
8351
8352 * xdisp.c (redisplay_internal): Fix prototype.
8353
8354 2011-03-31 Eli Zaretskii <eliz@gnu.org>
8355
8356 * xdisp.c (SCROLL_LIMIT): New macro.
8357 (try_scrolling): Use it when setting scroll_limit.
8358 Limit scrolling to 100 screen lines.
8359 (redisplay_window): Even when falling back on "recentering",
8360 position point in the window according to scroll-conservatively,
8361 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
8362
8363 (try_scrolling): When point is above the window, allow searching
8364 as far as scroll_max, or one screenful, to compute vertical
8365 distance from PT to the scroll margin position. This prevents
8366 try_scrolling from unnecessarily failing when
8367 scroll-conservatively is set to a value slightly larger than the
8368 window height. Clean up the case of PT below the margin at bottom
8369 of window: scroll_max can no longer be INT_MAX. When aggressive
8370 scrolling is in use, don't let point enter the opposite scroll
8371 margin as result of the scroll.
8372 (syms_of_xdisp) <scroll-conservatively>: Document the
8373 threshold of 100 lines for never-recentering scrolling.
8374
8375 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
8376
8377 * dispextern.h (move_it_by_lines):
8378 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
8379 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
8380 (message_log_check_duplicate): Remove parameters `prev_bol' and
8381 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
8382 (redisplay_internal): Remove parameter `preserve_echo_area',
8383 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
8384
8385 * indent.c (Fvertical_motion):
8386 * window.c (window_scroll_pixel_based, Frecenter):
8387 Don't pass `need_y_p' to `move_it_by_lines'.
8388
8389 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
8390
8391 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
8392 steal a few bits to be more compact.
8393 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
8394 Remove unneeded casts.
8395
8396 * bytecode.c (Fbyte_code): CAR and CDR can GC.
8397
8398 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
8399
8400 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
8401 binding" message (bug#7967).
8402
8403 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
8404
8405 Fix more problems found by GCC 4.6.0's static checks.
8406
8407 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
8408 Remove unused local var.
8409
8410 * editfns.c (Fmessage_box): Remove unused local var.
8411
8412 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
8413 (note_mode_line_or_margin_highlight, note_mouse_highlight):
8414 Omit unused local vars.
8415 * window.c (shrink_windows): Omit unused local var.
8416 * menu.c (digest_single_submenu): Omit unused local var.
8417 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
8418 Omit unused local var.
8419
8420 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
8421 Don't assume string length fits in int.
8422 (keyremap_step, read_key_sequence): Use size_t for sizes.
8423 (read_key_sequence): Don't check last_real_key_start redundantly.
8424
8425 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
8426 instead of alloca (Bug#8344).
8427
8428 * eval.c (Fbacktrace): Don't assume nargs fits in int.
8429 (Fbacktrace_frame): Don't assume nframes fits in int.
8430
8431 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
8432
8433 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
8434 concerns.
8435
8436 * term.c (produce_glyphless_glyph): Remove unnecessary test.
8437
8438 * cm.c (calccost): Turn while-do into do-while, for clarity.
8439
8440 * keyboard.c (syms_of_keyboard): Use the same style as later
8441 in this function when indexing through an array. This also
8442 works around GCC bug 48267.
8443
8444 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
8445
8446 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
8447
8448 * chartab.c (sub_char_table_ref_and_range): Redo for slight
8449 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
8450
8451 * keyboard.c, keyboard.h (num_input_events): Now size_t.
8452 This avoids undefined behavior on integer overflow, and is a bit
8453 more convenient anyway since it is compared to a size_t variable.
8454
8455 Variadic C functions now count arguments with size_t, not int.
8456 This avoids an unnecessary limitation on 64-bit machines, which
8457 caused (substring ...) to crash on large vectors (Bug#8344).
8458 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
8459 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
8460 All variadic functions and their callers changed accordingly.

8462 * data.c (arith_driver, float_arith_driver): Likewise.
8463 * editfns.c (general_insert_function): Likewise.
8464 * eval.c (struct backtrace.nargs, interactive_p)
8465 (internal_condition_case_n, run_hook_with_args, apply_lambda)
8466 (funcall_lambda, mark_backtrace): Likewise.
8467 * fns.c (concat): Likewise.
8468 * frame.c (x_set_frame_parameters): Likewise.
8469 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
8470 0 if not found, not -1. All callers changed.
8471
8472 * alloc.c (garbage_collect): Don't assume stack size fits in int.
8473 (stack_copy_size): Now size_t, not int.
8474 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
8475

8480 All callers changed.
8481
8482 * lisp.h (multibyte_char_to_unibyte):
8483 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
8484 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
8485 * character.h (CHAR_TO_BYTE8):
8486 * cmds.c (internal_self_insert):
8487 * editfns.c (general_insert_function):
8488 * keymap.c (push_key_description):
8489 * search.c (Freplace_match):
8490 * xdisp.c (message_dolog, set_message_1): All callers changed.
8491

8493
8494 * keyboard.c (safe_run_hook_funcall): New function.
8495 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
8496 don't set the hook to nil, but remove the offending function instead.
8497 (Qcommand_hook_internal): Remove, unused.
8498 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
8499 Vcommand_hook_internal.
8500
8501 * eval.c (enum run_hooks_condition): Remove.
8502 (funcall_nil, funcall_not): New functions.
8503 (run_hook_with_args): Call each function through a `funcall' argument.
8504 Remove `cond' argument, now redundant.
8505 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
8506 (Frun_hook_with_args_until_failure): Adjust accordingly.
8507 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
8508
8509 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
8510
8511 * dispextern.h (string_buffer_position): Remove declaration.
8512
8513 * print.c (strout): Remove parameter `multibyte', unused since
8514 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
8515
8516 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
8517 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
8518 All callers changed.
8519
8520 * w32.c (_wsa_errlist): Use braces for struct initializers.
8521

8546 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
8547
8548 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
8549
8550 * nsmenu.m (runDialogAt): Remove argument to timer_check.
8551

8560
8561 2011-03-26 Eli Zaretskii <eliz@gnu.org>
8562
8563 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
8564 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
8565
8566 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
8567
8568 * w32.c (read_unc_volume): Use parameter `henum', instead of
8569 global variable `wget_enum_handle'.
8570
8571 * keymap.c (describe_vector): Remove parameters `indices' and
8572 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
8573 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
8574
8575 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
8576
8577 * keyboard.c (timer_check): Remove parameter `do_it_now',
8578 unused since 1996-04-12T06:01:29Z!rms@gnu.org.

8583 * w32menu.c (w32_menu_display_help):
8584 * xmenu.c (show_help_event, menu_help_callback):
8585 Adjust calls to `show_help_echo'.
8586
8587 * gtkutil.c (xg_maybe_add_timer):
8588 * keyboard.c (readable_events):
8589 * process.c (wait_reading_process_output):
8590 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
8591

8644
8645 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
8646
8647 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
8648 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
8649 (Fx_close_connection): Remove unused variable `i'.
8650
8651 * w32font.c (w32font_draw): Return number of glyphs.
8652 (w32font_open_internal): Remove unused variable `i'.
8653 (w32font_driver): Add missing initializer.
8654
8655 * w32menu.c (utf8to16): Remove unused variable `utf16'.

8666
8667 2011-03-23 Julien Danjou <julien@danjou.info>
8668
8669 * term.c (Fsuspend_tty, Fresume_tty):
8670 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
8671 * window.c (temp_output_buffer_show):
8672 * insdel.c (signal_before_change):
8673 * frame.c (Fhandle_switch_frame):
8674 * fileio.c (Fdo_auto_save):
8675 * emacs.c (Fkill_emacs):
8676 * editfns.c (save_excursion_restore):
8677 * cmds.c (internal_self_insert):
8678 * callint.c (Fcall_interactively):
8679 * buffer.c (Fkill_all_local_variables):
8680 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
8681 Use Frun_hooks.
8682 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
8683 unconditionally since it does the check itself.
8684
8685 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
8686
8687 Fix more problems found by GCC 4.5.2's static checks.
8688
8689 * coding.c (encode_coding_raw_text): Avoid unnecessary test
8690 the first time through the loop, since we know p0 < p1 then.
8691 This also avoids a gcc -Wstrict-overflow warning.
8692
8693 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
8694 leading to a memory leak, possible in functions like
8695 load_charset_map_from_file that can allocate an unbounded number
8696 of objects (Bug#8318).
8697
8698 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
8699 that could (at least in theory) be that large.
8700
8701 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
8702 This is less likely to overflow, and avoids undefined behavior if
8703 overflow does occur. All callers changed. Use strtoul to scan
8704 for the unsigned long integer.
8705 (pint2hrstr): Simplify and tune code slightly.
8706 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
8707
8708 * scroll.c (do_scrolling): Work around GCC bug 48228.
8709 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
8710
8711 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
8712 This also avoids a warning with gcc -Wstrict-overflow.
8713 (validate_x_resource_name): Simplify count usage.
8714 This also avoids a warning with gcc -Wstrict-overflow.
8715
8716 * fileio.c (Fcopy_file): Report error if fchown or fchmod
8717 fail (Bug#8306).
8718
8719 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
8720
8721 * process.c (Fmake_network_process): Use socklen_t, not int,
8722 where POSIX says socklen_t is required in portable programs.
8723 This fixes a porting bug on hosts like 64-bit HP-UX, where
8724 socklen_t is wider than int (Bug#8277).
8725 (Fmake_network_process, server_accept_connection):
8726 (wait_reading_process_output, read_process_output):
8727 Likewise.
8728
8729 * process.c: Rename or move locals to avoid shadowing.
8730 (list_processes_1, Fmake_network_process):
8731 (read_process_output_error_handler, exec_sentinel_error_handler):
8732 Rename or move locals.
8733 (Fmake_network_process): Define label "retry_connect" only if needed.
8734 (Fnetwork_interface_info): Fix pointer signedness.
8735 (process_send_signal): Add cast to avoid pointer signedness problem.
8736 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
8737 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
8738
8739 Make tparam.h and terminfo.c consistent.
8740 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
8741 Include tparam.h instead, since it declares them.
8742 * cm.h (PC): Remove extern decl; tparam.h now does this.
8743 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.

8745 (tparm): Make 1st arg a const pointer in decl. Put it at top level.

8806 This should get cleaned up, so that child_setup has the
8807 same signature on all platforms.
8808
8809 * callproc.c (call_process_cleanup): Now static.
8810 (relocate_fd): Rename locals to avoid shadowing.

8812 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
8813
8814 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
8815 not to be necessary, and produces flickering.

8971 (Fmemory_limit): Cast sbrk's returned value to char *.

8978 Use functions, not macros, for up- and down-casing (Bug#8254).
8979 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8980 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
8981 to use the following functions instead of these macros.
8982 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
8983 EMACS_INT, since callers assume the returned value fits in int.

8986 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

8996 (regex_compile, re_match_2_internal): Mark locals as initialized.
8997 (RETALLOC_IF): Define only if needed.
8998 (WORDCHAR_P): Likewise. This one is never needed, but is used
8999 only in a comment talking about a compiler bug, so put inside
9000 the #if 0 of that comment.
9001 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
9002 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

9020 Rename locals to avoid shadowing.
9021 (Fvertical_motion): Mark locals as initialized.
9022

9027
9028 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
9029 New macros, so that the caller can use some names other than
9030 gcpro1, gcpro2, etc.
9031 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
9032 of the new macros.
9033 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
9034 argument, for consistency with GCPRO2_VAR, etc: it is now the
9035 prefix of the variable, not the variable itself. All uses
9036 changed.

9038 Rename locals to avoid shadowing.
9039
9040 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
9041 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
9042 dired.c's scmp function, had undefined behavior.
9043 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
9044 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
9045 * buffer.h: ... to here, because these macros use current_buffer,
9046 and the new implementation with inline functions needs to have
9047 current_buffer in scope now, rather than later when the macros
9048 are used.
9049 (downcase, upcase1): New static inline functions.
9050 (DOWNCASE, UPCASE1): Reimplement using these functions.
9051 This avoids undefined behavior in expressions like
9052 DOWNCASE (x) == DOWNCASE (y), which previously suffered
9053 from race conditions in accessing the global variables
9054 case_temp1 and case_temp2.
9055 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
9056 * lisp.h (case_temp1, case_temp2): Remove their decls.
9057 * character.h (ASCII_CHAR_P): Move from here ...
9058 * lisp.h: ... to here, so that the inline functions mentioned

9062
9063 * fileio.c (file_name_as_directory, directory_file_name):

9065 Now static.
9066 (file_name_as_directory): Use const pointers when appropriate.
9067 (Fexpand_file_name): Likewise. In particular, newdir might

9070 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
9071 signedness issues.

9077 to avoid shadowing.
9078
9079 * marker.c (bytepos_to_charpos): Remove; unused.
9080

9082 so that gcc does not warn that these functions aren't declared.
9083
9084 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
9085 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

9090 (lock_file_1): Rename local to avoid shadowing.
9091
9092 * buffer.c (fix_overlays_before): Mark locals as initialized.
9093 (fix_start_end_in_overlays): Likewise. This function should be
9094 simplified by using pointers-to-pointers, but that's a different
9095 matter.
9096 (switch_to_buffer_1): Now static.
9097 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
9098 (report_overlay_modification): Rename locals to avoid shadowing.
9099
9100 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
9101 Fix pointer signedness issue.
9102 (sys_subshell): Mark local as volatile if checking for lint,
9103 to suppress a gcc -Wclobbered warning that does not seem to be right.
9104 (MAXPATHLEN): Define only if needed.
9105
9106 * process.c (serial_open, serial_configure): Move decls from here ...
9107 * systty.h: ... to here, so that they can be checked.
9108
9109 * fns.c (get_random, seed_random): Move extern decls from here ...
9110 * lisp.h: ... to here, so that they can be checked.

9117 Now static.
9118 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.

9140
9141 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
9142 (DEFINE_DUMMY_FUNCTION): New macro.

9146 if GCC considers string literals to be constants.
9147
9148 * lisp.h (fatal_error_signal): Add decl, since it's exported.
9149
9150 * dbusbind.c: Pointer signedness fixes.
