[bpt/emacs.git] / src / ChangeLog
1 2012-04-07 Eli Zaretskii <eliz@gnu.org>
2
3 * indent.c (Fvertical_motion): If there is a display string at
4 point, use it.vpos to compute how many lines to backtrack after
5 move_it_to point. (Bug#11133)
6
7 2012-04-06 Eli Zaretskii <eliz@gnu.org>
8
9 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12 macros related to unification of CJK characters. For the details,
13 see the discussion following the message here:
14 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
15
16 2012-04-04 Chong Yidong <cyd@gnu.org>
17
18 * keyboard.c (Vdelayed_warnings_list): Doc fix.
19
20 2012-04-01 Eli Zaretskii <eliz@gnu.org>
21
22 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
23 instead of alloca. (Bug#11138)
24
25 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
26
27 * w32menu.c (is_simple_dialog): Properly check lisp types.
28 (Bug#11141)
29
30 2012-03-31 Eli Zaretskii <eliz@gnu.org>
31
32 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
33 position we get to after a call to move_it_to fails the
34 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
35 only if we wind up in a string from display property. (Bug#11063)
36
37 * window.c (Fdelete_other_windows_internal): Invalidate the row
38 and column information about mouse highlight, so that redisplay
39 restores it after reallocating the glyph matrices. (Bug#7464)
40
41 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
42 string comes from a `display' text property, use the buffer
43 position of that property as if we actually saw that position in
44 the row's glyphs.
45 (move_it_by_lines): Remove the assertion that
46 "it->current_x == 0 && it->hpos == 0" which can be legitimately
47 violated when there's a before-string at the beginning of a line.
48 (Bug#11063)
49
50 2012-03-30 Eli Zaretskii <eliz@gnu.org>
51
52 * xdisp.c (append_space_for_newline): If the default face was
53 remapped, use the remapped face for the appended newline.
54 (extend_face_to_end_of_line): Use the remapped default face for
55 extending the face to the end of the line.
56 (display_line): Call extend_face_to_end_of_line when the default
57 face was remapped. (Bug#11068)
58
59 2012-03-29 Eli Zaretskii <eliz@gnu.org>
60
61 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
62
63 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
64
65 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
66
67 2012-03-27 Glenn Morris <rgm@gnu.org>
68
69 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
70 Doc fixes.
71
72 2012-03-26 Kenichi Handa <handa@m17n.org>
73
74 * dispextern.h (struct glyph): Fix previous change. Change the
75 bit length of glyphless.ch to 25 (Bug#11082).
76
77 2012-03-26 Chong Yidong <cyd@gnu.org>
78
79 * keyboard.c (Vselection_inhibit_update_commands): New variable.
80 (command_loop_1): Use it; inhibit selection update for
81 handle-select-window too (Bug#8996).
82
83 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
84
85 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
86
87 2012-03-25 Kenichi Handa <handa@m17n.org>
88
89 * dispextern.h (struct glyph): Change the bit length of
90 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
91
92 2012-03-24 Eli Zaretskii <eliz@gnu.org>
93
94 * s/ms-w32.h (tzname): Include time.h before redirecting to
95 _tzname. Fixes the MSVC build. (Bug#9960)
96
97 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
98
99 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
100 characters.
101
102 * xterm.c (XTread_socket): Only modify handling_signal if
103 !SYNC_INPUT. (Bug#11080)
104
105 2012-03-23 Eli Zaretskii <eliz@gnu.org>
106
107 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
108 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
109 when fetching a multibyte character consumes more bytes than
110 CHAR_BYTES returns, due to unification of CJK characters in
111 string_char. (Bug#11073)
112
113 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
114
115 * process.c (wait_reading_process_output): Handle pty disconnect

117
118 2012-03-22 Chong Yidong <cyd@gnu.org>
119
120 * dispextern.h (struct it): New member string_from_prefix_prop_p.
121
122 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
123 Mark string as coming from a prefix property.
124 (handle_face_prop): Use default face for prefix strings (Bug#4281).
125 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
126
127 2012-03-21 Chong Yidong <cyd@gnu.org>
128
129 * xfaces.c (Vface_remapping_alist): Doc fix.
130
131 2012-03-20 Eli Zaretskii <eliz@gnu.org>
132
133 * w32proc.c (Fw32_set_console_codepage)

135 Doc fixes.
136
137 2012-03-20 Chong Yidong <cyd@gnu.org>
138
139 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
140 to reflect default non-nil value of redisplay-dont-pause.
141
142 2012-03-19 Kenichi Handa <handa@m17n.org>
143
144 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
145 it fit in a valid range (Bug#11003).
146
147 2012-03-18 Eli Zaretskii <eliz@gnu.org>
148
149 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
150 that is not from display property, accept the row as a "cursor
151 row" if one of the string's character has a non-nil `cursor'
152 property. Fixes cursor positioning when there are newlines in
153 overlay strings, e.g. in icomplete.el. (Bug#11035)
154
155 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
156
157 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
158
159 2012-03-12 Chong Yidong <cyd@gnu.org>
160
161 * eval.c (inhibit_lisp_code): Rename from
162 inhibit_window_configuration_change_hook; move from window.c.
163
164 * xfns.c (unwind_create_frame_1, Fx_create_frame):
165 * window.c (run_window_configuration_change_hook)
166 (syms_of_window): Callers changed.

182
183 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
184
185 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
186 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
187 zero (Bug#10954).
188
189 2012-03-03 Glenn Morris <rgm@gnu.org>
190
191 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

196 position past the first glyph_row that ends at ZV. (Bug#10902)
197 (redisplay_window, next_element_from_string): Fix typos in
198 comments.
199 (redisplay_window): Pass to move_it_vertically the margin in
200 pixels, not in screen lines.
201
202 2012-03-02 Glenn Morris <rgm@gnu.org>
203
204 * buffer.c (buffer-list-update-hook): Doc fix.
205
206 2012-02-29 Eli Zaretskii <eliz@gnu.org>
207

212 stack, pop the stack. (Bug#10903)

215
216 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
217 Suggested by Stefan Monnier in
218 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
219 * alloc.c (widen_to_Lisp_Object): New static function.
220 (mark_memory): Also mark Lisp_Objects by fetching pointer words
221 and widening them to Lisp_Objects. This would work even if
222 USE_LSB_TAG is defined and wide integers are used, which might
223 happen in a future version of Emacs.
224
225 2012-02-25 Chong Yidong <cyd@gnu.org>
226
227 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
228 Doc fix.
229
230 * xselect.c (Fx_selection_exists_p): Doc fix.
231 (x_clipboard_manager_save_all): Print an informative message
232 before saving to clipboard manager.
233
234 2012-02-24 Chong Yidong <cyd@gnu.org>
235
236 * keyboard.c (process_special_events): Handle all X selection
237 requests in kbd_buffer, not just the next one (Bug#8869).
238
239 2012-02-23 Chong Yidong <cyd@gnu.org>
240
241 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
242 call when setting menu-bar-lines and tool-bar-lines parameters.
243 (unwind_create_frame_1): New helper function.
244
245 * window.c (inhibit_window_configuration_change_hook): New var.
246 (run_window_configuration_change_hook): Obey it.
247 (syms_of_window): Initialize it.
248
249 2012-02-22 Chong Yidong <cyd@gnu.org>
250
251 * xterm.c (x_draw_image_relief): Add missing type check for
252 Vtool_bar_button_margin (Bug#10743).
253
254 2012-02-21 Chong Yidong <cyd@gnu.org>
255
256 * fileio.c (Vfile_name_handler_alist): Doc fix.
257
258 * buffer.c (Fget_file_buffer): Protect against invalid file

264 when computing $valmask.
265
266 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
267 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
268 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
269 It's useless in that case, and it can cause problems on hosts
270 that allocate halves of EMACS_INT values separately.
271 Reported by Dan Horák. Diagnosed by Andreas Schwab in
272 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
273 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
274 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
275 it avoids undefined behavior on hosts where shifting right by more
276 than the word width has undefined behavior.
277
278 2012-02-19 Chong Yidong <cyd@gnu.org>
279
280 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
281 (Funhandled_file_name_directory, Ffile_name_as_directory)
282 (Fdirectory_file_name, Fexpand_file_name)
283 (Fsubstitute_in_file_name): Protect against invalid file handler
284 return values (Bug#10845).
285
286 2012-02-18 Eli Zaretskii <eliz@gnu.org>
287
288 * .gdbinit (pitx): Fix incorrect references to fields of the
289 iterator stack.
290
291 2012-02-17 Chong Yidong <cyd@gnu.org>
292
293 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
294
295 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
296
297 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
298 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
299
300 2012-02-15 Chong Yidong <cyd@gnu.org>
301
302 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
303 marked as special. Also, starting docstrings with * is obsolete.
304

317
318 2012-02-12 Chong Yidong <cyd@gnu.org>
319
320 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
321 as that creates a dangerous corner case.
322
323 * window.c (Fdelete_window_internal): Invalidate the mouse
324 highlight (Bug#9904).
325
326 2012-02-12 Glenn Morris <rgm@gnu.org>
327
328 * xselect.c (Fx_own_selection_internal)
329 (Fx_get_selection_internal, Fx_disown_selection_internal)

332 (Fx_disown_selection_internal, Fx_selection_exists_p)
333 (Fx_selection_owner_p, Fx_get_selection_internal):
334 Sync docs and argument specs with the xselect.c versions.

353
354 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
355

357
358 * buffer.c (Fbuffer_local_variables)
359 (buffer_lisp_local_variables): Handle unbound vars correctly;

363
364 * image.c (Fimagemagick_types): Doc fix.

369
370 2012-02-06 Chong Yidong <cyd@gnu.org>
371
372 * doc.c (store_function_docstring): Avoid applying docstring of
373 alias to base function (Bug#2603).
374
375 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

383
384 2012-02-04 Eli Zaretskii <eliz@gnu.org>
385
386 * w32.c (get_emacs_configuration_options):
387 Include --enable-checking, if specified, in the return value.
388
389 2012-02-04 Martin Rudalics <rudalics@gmx.at>
390
391 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
392 after rounding frame sizes. (Bug#9723)
393
394 2012-02-04 Eli Zaretskii <eliz@gnu.org>
395
396 * keyboard.c (adjust_point_for_property): Don't position point

398
399 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
400
401 Handle overflow when computing char display width (Bug#9496).
402 * character.c (char_width): Return EMACS_INT, not int.
403 (char_width, c_string_width): Check for overflow when
404 computing the width; this is possible now that individual
405 characters can have unbounded width. Problem introduced
406 by merge from Emacs 23 on 2012-01-19.
407
408 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
409

411 :ignore in the docstring.
412
413 2012-02-02 Glenn Morris <rgm@gnu.org>
414
415 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
416
417 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
418 Unconditionally set to t. (Bug#10673)

426 0, do not call append_composite_glyph.
427
428 2012-02-02 Kenichi Handa <handa@m17n.org>
429
430 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
431 NULL (Bug#6988).
432 (x_produce_glyphs): If the component of a composition is a null
433 string, set it->pixel_width to 1 to avoid zero-width glyph.
434
435 2012-02-01 Eli Zaretskii <eliz@gnu.org>
436
437 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
438 first 2 arguments are identical. This makes inserting large
439 output from a subprocess an order of magnitude faster on
440 MS-Windows, where all sbrk'ed memory is always contiguous.
441
442 2012-01-31 Glenn Morris <rgm@gnu.org>
443

1055 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
1056 Otherwise, valgrind does not work on some platforms.
1057 Problem reported by Andreas Schwab in
1058 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
1059 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
1060 is set, removing the need for VIRT_ADDRESS_VARIES.
1061 (PURE_P): Use a more-efficient implementation that needs just one
1062 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
1063 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
1064 to 4 (xorl, subq, cmpq, setbe).
1065 * alloc.c (pure): Always extern now, since that's the
1066 VIRT_ADDR_VARIES behavior.
1067 (PURE_POINTER_P): Use a single comparison, not two, for
1068 consistency with the new puresize.h.
1069 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
1070 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
1071 Remove VIRT_ADDR_VARIES no longer needed.

1076 (erase_phys_cursor, update_window_cursor, show_mouse_face)
1077 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
1078 behave as if the cursor position were at the window margin.
1079
1080 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
1081 and the cursor position is out of bounds, behave as if the cursor
1082 position were at the window margin. (Bug#10075)
1083
1084 2011-11-18 Chong Yidong <cyd@gnu.org>
1085
1086 * window.c (Fwindow_combination_limit): Make first argument
1087 non-optional, since it is meaningless for live windows like the
1088 selected window.
1089
1090 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>
1091
1092 * keymap.c (Fwhere_is_internal): Add missing RETURN_UNGCPROs.

1102 hash values of the two rows.
1103 (copy_row_except_pointers): Preserve the used[] arrays and the
1104 hash values of the two rows. (Bug#10035)
1105 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
1106
1107 * xdisp.c (row_hash): New function, body extracted from
1108 compute_line_metrics.
1109 (compute_line_metrics): Call row_hash, instead of computing the
1110 hash code inline.
1111
1112 * dispnew.c (verify_row_hash): Call row_hash for computing the
1113 hash code of a row, instead of duplicating code from xdisp.c.
1114
1115 * dispextern.h (row_hash): Add prototype.

1151 * image.c (imagemagick_load_image): Fix typo.
1152
1153 2011-11-14 Eli Zaretskii <eliz@gnu.org>
1154
1155 * xdisp.c (display_line): Move the call to
1156 highlight_trailing_whitespace before the call to
1157 compute_line_metrics, since the latter needs to see the final
1158 faces of all the glyphs to compute ROW's hash value.
1159 Fixes assertion violations in row_equal_p. (Bug#10035)
1160
1161 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
1162
1163 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
1164 just return (bug#10044).
1165
1166 2011-11-12 Eli Zaretskii <eliz@gnu.org>
1167
1168 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
1169 with user-defined heap size. Bump the default size of the temacs
1170 heap to 27MB, to avoid memory warning when running temacs.
1171 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
1172
1173 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
1174 current_matrix and desired_matrix. (Bug#9990)
1175 (verify_row_hash) [XASSERTS]: New function.
1176 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
1177 that the hash value of glyph rows is correct.

1222 Avoid some portability problems by eschewing 'extern inline' functions.
1223 The trivial performance wins aren't worth the portability hassles; see
1224 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
1225 et seq.
1226 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

1254
1255 * w32.c (check_windows_init_file): Don't look for term/w32-win.el

1257 of temacs in GUI mode.
1258
1259 2011-11-07 Martin Rudalics <rudalics@gmx.at>
1260

1273
1274 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
1275 This is also needed for porting to any host where GC_MARK_STACK is
1276 not GC_MAKE_GCPROS_NOOPS.
1277 (which_symbols): Use it.
1278
1279 2011-11-07 Kenichi Handa <handa@m17n.org>
1280
1281 * coding.c (coding_set_destination): Check coding->src_pos only
1282 when coding->src_object is a buffer (bug#9910).
1283
1284 * process.c (send_process): Set the member src_multibyte of coding
1285 to 0 (bug#9911) when sending a unibyte text.
1286

1291
1292 * xmenu.c (cleanup_widget_value_tree): New function.
1293 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
1294 calling free_menubar_widget_value_tree directly (Bug#9830).
1295
1296 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
1297

1300 (window_box_width, window_box_left, window_box_left_offset)
1301 (window_box_right, window_box_right_offset): Declare extern.
1302 Otherwise, these inline functions do not conform to C99 and
1303 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
1304 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
1305 * intervals.c (adjust_intervals_for_insertion)
1306 (adjust_intervals_for_deletion): Now extern, because otherwise the
1307 extern inline functions 'offset_intervals' couldn't refer to it.
1308 (static_offset_intervals): Remove.
1309 (offset_intervals): Rewrite using the old contents of
1310 static_offset_intervals. The old version didn't conform to C99
1311 because an extern inline function contained a reference to an
1312 identifier with static linkage.
1313
1314 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
1315

1567 non-NULL, regardless of GNUTLS_INITSTAGE.
1568 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
1569 an error. Set process slots as soon as we allocate them.
1570
1571 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.

1615 current character, check also for next_en_type being WEAK_EN.
1616 (bidi_resolve_weak): Don't enter the expensive loop if the current
1617 position is before next_en_pos. Record the bidi type of the first
1618 non-ET, non-BN character we find, in addition to its position.
1619 (bidi_level_of_next_char): Invalidate next_en_type when
1620 next_en_pos is over-stepped.

1623
1624 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
1625 * editfns.c: Rewrite current-time-zone so that it invokes
1626 the equivalent of (format-time-string "%Z") to get the time zone name.
1627 This fixes a bug when the time zone name contains characters that
1628 need converting from the system time locale to Emacs internal format.
1629 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
1630 that patch fixed format-time-string to do the conversion, but
1631 I forgot to fix current-time-zone.
1632 (format_time_string): New function, containing most of
1633 what Fformat_time_string used to contain.
1634 (Fformat_time_string): Rewrite in terms of format_time_string.
1635 This doesn't change this function's behavior.
1636 (current-time-zone): Rewrite to use format_time_string.
1637 This fixes the bug reported by Michael Schierl in
1638 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
1639 Jason Rumney's 2007-06-07 change worked around this bug, but
1640 didn't fix it.
1641 * systime.h (tzname, timezone): Remove no-longer-used declarations.
1642
1643 2011-10-19 Eli Zaretskii <eliz@gnu.org>
1644
1645 * xdisp.c (start_display): If the character at POS is displayed
1646 via a display vector, reset IT->current.dpvec_index to zero.
1647 (try_window_reusing_current_matrix): If a line ends in a display
1648 vector or the next line starts in a display vector, continue
1649 redrawing the window even though the character position of
1650 start_row was reached.
1651 (Bug#9771, part 2)
1652
1653 2011-10-18 Chong Yidong <cyd@gnu.org>

1658 2011-10-18 Eli Zaretskii <eliz@gnu.org>
1659
1660 Fix part 3 of bug#9771.
1661 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
1662 (bidi_resolve_neutral): Don't enter the expensive loop looking for
1663 non-neutral characters if the current character is a paragraph
1664 separator (a.k.a. Newline). This avoids running the same
1665 expensive loop twice, once when we consume the preceding newline
1666 and the other time when the line actually needs to be displayed.
1667 Avoid the loop when we see neutrals on the base embedding level
1668 following a character whose directionality is the same as the
1669 paragraph's. This avoids running the expensive loop when a line
1670 ends in a long sequence of neutrals, like control characters.
1671 Add assertion against STRONG_AL type. Slightly rearrange code
1672 that determines the type of a neutral given the first non-neutral
1673 that follows it.
1674 (bidi_level_of_next_char): Set next_en_pos to zero when
1675 invalidating its info.
1676
1677 2011-10-17 Eli Zaretskii <eliz@gnu.org>
1678
1679 * xdisp.c (push_display_prop): Determine whether to record string
1680 or buffer position by IT->string, not by IT->method. Allow
1681 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
1682 (move_it_vertically_backward): Don't look for character position
1683 immediately after the newline when in a continuation line.
1684 (Bug#9771, part 1)
1685
1686 2011-10-15 Martin Rudalics <rudalics@gmx.at>

1702
1703 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
1704 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
1705 cursor motion with <left> and <right> arrow keys.
1706
1707 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
1708 some callers set that themselves.
1709
1710 2011-10-12 Eli Zaretskii <eliz@gnu.org>
1711
1712 * xdisp.c (find_row_edges): Handle the case where ROW comes from a

1714 is empty. (Bug#9739) (Bug#9738)
1715
1716 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

1742 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
1743
1744 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
1745 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
1746 matching a pp-number. Rename parameter var to var1.
1747
1748 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
1749
1750 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
1751
1752 2011-10-08 Glenn Morris <rgm@gnu.org>
1753
1754 * callint.c (Fcall_interactively): Give a more explicit error for the
1755 'c' case with a non-character input. (Bug#8479)
1756
1757 2011-10-08 Eli Zaretskii <eliz@gnu.org>
1758
1759 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
1760 lines.
1761 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
1762 lines that are hscrolled on the left.
1763
1764 * dispnew.c (buffer_posn_from_coords): Account for a possible
1765 presence of header-line. (Bug#4426)
1766
1767 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
1768
1769 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
1770 Don't advertise functionality which we discourage or doesn't work.
1771
1772 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
1773
1774 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
1775 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
1776 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
1777 this makes Emacs dump core during garbage collection on rare
1778 occasions. sizeof is obviously inferior to offsetof here, so
1779 stick with offsetof.
1780 (GC_POINTER_ALIGNMENT): New macro.
1781 (mark_memory): Omit 3rd (offset) arg; caller changed.
1782 Don't assume EMACS_INT alignment is the same as pointer alignment.
1783
1784 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
1785
1786 * keyboard.c (read_key_sequence_remapped): New var.
1787 (read_key_sequence): Compute remapping in the right buffer.
1788 (command_loop_1): Use read_key_sequence's remapping directly.
1789
1790 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1791
1792 * dired.c (file_name_completion): Don't expand file name.
1793 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
1794 before checking file name handler.
1795
1796 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
1797 they've been requested explicitly (bug#9591).
1798
1799 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
1800
1801 * keymap.c (Fsingle_key_description): Use make_specified_string
1802 instead of build_string to build string from push_key_description.
1803 (Bug#5193)
1804
1805 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1806
1807 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
1808 This fixes a Y2038 bug on 64-bit hosts.
1809 * buffer.c (reset_buffer):
1810 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
1811 (Fclear_buffer_auto_save_failure):
1812 Use 0, not -1, to represent an unset failure time, since time_t
1813 might not be signed.
1814
1815 Remove dependency on glibc malloc internals.
1816 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1817 Move back here from lisp.h, but with their new implementations.
1818 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1819 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
1820 * charset.c (charset_table_init): New static var.
1821 (syms_of_charset): Use it instead of xmalloc. This removes a
1822 dependency on glibc malloc internals. See Eli Zaretskii's comment in
1823 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
1824 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1825 Move back to alloc.c.
1826 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1827 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
1828
1829 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
1830
1831 * nsterm.m (windowDidResize): Call x_set_window_size only when
1832 ns_in_resize is true. Otherwise set pixelwidth/height and
1833 call change_frame_size (Bug#9628).
1834
1835 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1836
1837 Port --enable-checking=all to Fedora 14 x86-64.
1838 * charset.c (syms_of_charset): Also account for glibc malloc's
1839 internal overhead when calculating the initial malloc maximum.
1840
1841 Port --enable-checking=all to Fedora 14 x86.
1842 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1843 Move to lisp.h.
1844 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
1845 (overrun_check_realloc, overrun_check_free):
1846 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
1847 That way, xmalloc returns a properly-aligned pointer even if
1848 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
1849 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
1850 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
1851 into account when calculating the initial malloc maximum.
1852 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1853 Move here from alloc.c, so that charset.c can use it too.
1854 Properly align; the old code wasn't right for common 32-bit hosts
1855 when configured with --enable-checking=all.
1856 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1857 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
1858
1859 2011-09-29 Eli Zaretskii <eliz@gnu.org>
1860
1861 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
1862 use EDOM.
1863
1864 2011-09-28 Eli Zaretskii <eliz@gnu.org>
1865
1866 * xdisp.c (compute_display_string_end): If there's no display
1867 string at CHARPOS, return -1.
1868
1869 * bidi.c (bidi_fetch_char): When compute_display_string_end
1870 returns a negative value, treat the character as a normal
1871 character not covered by a display string. (Bug#9624)
1872
1873 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
1874
1875 * lread.c (Fread_from_string): Fix typo in docstring.
1876
1877 2011-09-27 Eli Zaretskii <eliz@gnu.org>
1878
1879 * xdisp.c (handle_invisible_prop): If invisible text ends on a
1880 newline, reseat the iterator instead of bidi-iterating there one
1881 character at a time. (Bug#9610)
1882 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
1883 TO_CHARPOS if the bidi iterator is at base embedding level.
1884
1885 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
1886
1887 * lread.c (readevalloop): Use correct code for NBSP.
1888 (read1): Likewise. (Bug#9608)
1889
1890 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
1891
1892 * dbusbind.c (Fdbus_register_signal): When service is not
1893 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
1894
1895 2011-09-25 Glenn Morris <rgm@gnu.org>
1896
1897 * buffer.c (truncate-lines): Doc fix.
1898
1899 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
1900
1901 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
1902 (Fset_window_next_buffers): Doc fix.
1903
1904 2011-09-24 Glenn Morris <rgm@gnu.org>
1905
1906 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
1907
1908 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
1909
1910 Fix minor problems found by static checking.
1911 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
1912 * indent.c (Fvertical_motion): Fix == vs = typo.
1913
1914 2011-09-24 Eli Zaretskii <eliz@gnu.org>
1915
1916 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
1917 Default value is now t. Doc fix.
1918
1919 * indent.c (Fvertical_motion): Compute and apply the overshoot
1920 logic when moving up, not only when moving down. Fix the
1921 confusing name and values of the it_overshoot_expected variable;
1922 logic changes accordingly. (Bug#9254) (Bug#9549)
1923
1924 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
1925 CHARPOS is covered by a display string which includes newlines.
1926 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
1927 is covered by a display string with embedded newlines.
1928
1929 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
1930
1931 * dbusbind.c (Fdbus_register_signal): Add match rule to
1932 Vdbus_registered_objects_table. (Bug#9581)
1933 (Fdbus_register_method, Vdbus_registered_objects_table):
1934 Fix docstring.
1935
1936 2011-09-24 Jim Meyering <meyering@redhat.com>
1937
1938 do not ignore write error for any output size
1939 The previous change was incomplete.
1940 While it makes emacs --batch detect the vast majority of stdout
1941 write failures, errors were still ignored whenever the output size is
1942 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
1943 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
1944 && echo FAIL: ignored write error
1945 FAIL: ignored write error
1946 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
1947 && echo FAIL: ignored write error
1948 FAIL: ignored write error
1949 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
1950
1951 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
1952
1953 * emacs.c (Fkill_emacs): In noninteractive mode exit
1954 non-successfully if a write error occurred on stdout. (Bug#9574)
1955
1956 2011-09-21 Eli Zaretskii <eliz@gnu.org>
1957
1958 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
1959 the xassert test.
1960
1961 * dispextern.h (struct it): Update the comment documenting what
1962 can it->OBJECT be.
1963
1964 2011-09-20 Eli Zaretskii <eliz@gnu.org>
1965
1966 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
1967 a display string, extend search for cursor position to end of row.
1968 (find_row_edges): If the row ends in a newline from a display
1969 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
1970 Handle the case of a display string with multiple newlines.
1971 (Fcurrent_bidi_paragraph_direction): Fix search for previous
1972 non-empty line. Fixes confusing cursor motion with arrow keys at
1973 the beginning of a line that starts with whitespace.
1974
1975 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1976
1977 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
1978 (bug#9493).
1979

1981
1982 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
1983 boolean (Bug#9154).
1984
1985 2011-09-18 Eli Zaretskii <eliz@gnu.org>
1986
1987 * xdisp.c (display_line): Record maximum and minimum buffer
1988 positions even if no glyphs were produced (e.g., by a zero-width
1989 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
1990 buffer positions that will be removed from the glyph row because
1991 they don't fit.
1992 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
1993 column is beyond frame width: don't subtract 1 "pixel" when
1994 computing width of the stretch.
1995 (reseat_at_next_visible_line_start): Undo the change made on
1996 2011-09-17 that saved paragraph information and restored it after
1997 the call to `reseat'. (Bug#9545)
1998
1999 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2000
2001 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
2002 and turn window cursor on if cleared (Bug#9415).
2003
2004 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
2005
2006 * search.c (boyer_moore): Take unibyte characters from pattern
2007 literally. (Bug#9458)
2008
2009 2011-09-18 Eli Zaretskii <eliz@gnu.org>
2010
2011 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.

2014
2015 Fix minor problem found by static checking.
2016 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
2017 initialized, to pacify gcc -Wuninitialized.
2018
2019 * fileio.c: Report proper errno when syscall falls.
2020 (Finsert_file_contents): Save and restore errno,
2021 so that report_file_error outputs the correct diagnostic.
2022 (Fwrite_region) [CLASH_DETECTION]: Likewise.
2023
2024 2011-09-18 Eli Zaretskii <eliz@gnu.org>
2025
2026 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
2027
2028 2011-09-17 Eli Zaretskii <eliz@gnu.org>
2029
2030 * xdisp.c (produce_stretch_glyph): Another fix for changes made on

2032
2033 2011-09-17 Eli Zaretskii <eliz@gnu.org>
2034
2035 * xdisp.c (reseat_at_next_visible_line_start): Keep information
2036 about the current paragraph and restore it after the call to reseat.
2037
2038 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
2039 (bidi_find_paragraph_start): Search back for paragraph beginning
2040 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
2041 (bidi_move_to_visually_next): Only trigger paragraph-related
2042 computations when the last character is a newline or at EOB, not
2043 just any NEUTRAL_B. (Bug#9470)
2044
2045 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
2046 truncated lines if point is covered by a display string. (Bug#9524)
2047
2048 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
2049
2050 * xselect.c: Relax test for outgoing X longs (Bug#9498).
2051 (cons_to_x_long): New function.
2052 (lisp_data_to_selection_data): Use it. Correct the test for
2053 short-versus-long data; it was negated. Break out of vector
2054 loop, for efficiency, when a long datum is discovered.
2055
2056 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
2057
2058 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
2059
2060 2011-09-16 Eli Zaretskii <eliz@gnu.org>
2061
2062 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
2063 GCC PR/17406) by declaring this function with external scope.
2064
2065 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
2066
2067 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
2068 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
2069
2070 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
2071
2072 * editfns.c (Fformat): Correctly handle text properties on "%%".
2073

2080 * xdisp.c (get_next_display_element)
2081 (fill_composite_glyph_string): Add comments about special meaning
2082 of TAB characters in a composition.
2083
2084 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
2085
2086 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
2087 This occurs when processing a multibyte format.
2088 Problem reported by Wolfgang Jenker.
2089
2090 2011-09-15 Johan Bockgård <bojohan@gnu.org>
2091
2092 * xdisp.c (try_cursor_movement): Only check for exact match if

2105 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
2106
2107 * xselect.c: Use signed conversions more consistently (Bug#9498).
2108 (selection_data_to_lisp_data): Assume incoming selection data are
2109 signed integers, not unsigned. This is to be consistent with
2110 outgoing selection data, which was modified to use signed integers
2111 in as part of the fix to Bug#9196 in response to Jan D.'s comment
2112 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
2113 expects long, not unsigned long.
2114
2115 2011-09-14 Eli Zaretskii <eliz@gnu.org>
2116
2117 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect

2124
2125 2011-09-12 Eli Zaretskii <eliz@gnu.org>
2126
2127 * indent.c (compute_motion): Process display vector front to back
2128 rather than the other way around. (Bug#2496)
2129
2130 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2131
2132 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
2133
2134 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
2135
2136 * minibuf.c (Fread_from_minibuffer): Doc fix.

2147
2148 2011-09-11 Eli Zaretskii <eliz@gnu.org>
2149
2150 * fileio.c (Finsert_file_contents): If the file cannot be opened,
2151 set its "size" to -1. This will set the modtime_size field of
2152 the corresponding buffer to -1, which is what
2153 verify-visited-file-modtime expects for files that do not exist.

2156 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
2157
2158 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
2159 here ...
2160 * lisp.h: ... from here. push_key_description is no longer
2161 defined in keyboard.c, so its declaration should not be in
2162 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
2163 logically belongs with push_key_description.
2164
2165 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
2166
2167 * buffer.h: Include <sys/types.h> instead of <time.h>.
2168 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
2169 Problem reported by Herbert J. Skuhra.
2170
2171 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
2172
2173 * xml.c (parse_region): Make the parsing work for
2174 non-comment-starting XML files again (bug#9144).
2175
2176 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
2177
2178 * image.c (gif_load): Fix calculation of bottom and right corner.
2179 (Bug#9468)
2180
2181 2011-09-10 Eli Zaretskii <eliz@gnu.org>
2182
2183 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
2184 redisplay in small windows.
2185
2186 2011-09-09 Eli Zaretskii <eliz@gnu.org>
2187
2188 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
2189
2190 2011-09-08 Martin Rudalics <rudalics@gmx.at>
2191
2192 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
2193 Operate on live windows only.
2194
2195 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
2196
2197 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
2198
2199 2011-09-07 Eli Zaretskii <eliz@gnu.org>
2200
2201 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
2202 only under bidi iteration.
2203
2204 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
2205
2206 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
2207
2208 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2209
2210 isnan: Fix porting problem to Solaris 10 with bundled gcc.
2211 Without this fix, the command to link temacs failed due to an
2212 undefined symbol __builtin_isnan. This is because
2213 /usr/include/iso/math_c99.h #defines isnan(x) to
2214 __builtin_isnan(x), but the bundled gcc, which identifies itself
2215 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
2216 a __builtin_isnan.
2217 * floatfns.c (isnan): #undef, and then #define to a clone of
2218 what's in data.c.
2219 (Fisnan): Always define, since it's always available now.
2220 (syms_of_floatfns): Always define isnan at the Lisp level.
2221
2222 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2223
2224 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
2225
2226 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2227
2228 * fileio.c: Fix bugs with large file offsets (Bug#9428).
2229 The previous code assumed that file offsets (off_t values) fit in
2230 EMACS_INT variables, which is not true on typical 32-bit hosts.
2231 The code messed up by falsely reporting buffer overflow in cases
2232 such as (insert-file-contents "big" nil 1 2) into an empty buffer
2233 when "big" contains more than 2**29 bytes, even though this
2234 inserts just one byte and does not overflow the buffer.
2235 (Finsert_file_contents): Store file offsets as off_t
2236 values, not as EMACS_INT values. Check for overflow when
2237 converting between EMACS_INT and off_t. When checking for
2238 buffer overflow or for overlap, take the offsets into account.
2239 Don't use EMACS_INT for small values where int suffices.
2240 When checking for overlap, fix a typo: ZV was used where
2241 ZV_BYTE was intended.
2242 (Fwrite_region): Don't assume off_t fits into 'long'.
2243 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
2244
2245 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
2246
2247 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
2248
2249 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2250
2251 sprintf-related integer and memory overflow issues (Bug#9412).
2252
2253 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
2254 (esprintf, exprintf, evxprintf): New functions.
2255 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
2256 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
2257 (modify_event_symbol): Do not assume that the length of
2258 name_alist_or_stem is safe to alloca and fits in int.
2259 (Fexecute_extended_command): Likewise for function name and binding.
2260 (Frecursion_depth): Wrap around reliably on integer overflow.
2261 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
2262 since some callers pass EMACS_INT values.
2263 (Fsingle_key_description): Don't crash if symbol name contains more
2264 than MAX_ALLOCA bytes.
2265 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
2266 (get_minibuffer): Arg is now EMACS_INT, not int.
2267 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
2268 (esprintf, exprintf, evxprintf): New decls.
2269 * window.h (command_loop_level, minibuf_level): Reflect API changes.
2270
2271 * dbusbind.c (signature_cat): New function.
2272 (xd_signature, Fdbus_register_signal):
2273 Do not overrun buffer; instead, report string overflow.
2274
2275 * dispnew.c (add_window_display_history): Don't overrun buffer.
2276 Truncate instead; this is OK since it's just a log.
2277
2278 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
2279 even if the time zone offset is outlandishly large.
2280 Don't mishandle offset == INT_MIN.
2281
2282 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
2283 when creating daemon; the previous buffer-overflow check was incorrect.
2284
2285 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
2286 which has the guts of the old verror function.
2287
2288 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
2289 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
2290
2291 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
2292 (font_unparse_xlfd): Don't blindly alloca long strings.
2293 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
2294 fits in int, when using sprintf. Use single snprintf to count
2295 length of string rather than counting it via multiple sprintfs;
2296 that's simpler and more reliable.
2297 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
2298 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
2299 sprintf, in case result does not fit in int.
2300
2301 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
2302 (fontset_from_font): Print it.
2303
2304 * frame.c (tty_frame_count): Now printmax_t, not int.
2305 (make_terminal_frame, set_term_frame_name): Print it.
2306 (x_report_frame_params): In X, window IDs are unsigned long,
2307 not signed long, so print them as unsigned.
2308 (validate_x_resource_name): Check for implausibly long names,
2309 and don't assume name length fits in 'int'.
2310 (x_get_resource_string): Don't blindly alloca invocation name;
2311 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
2312 not fit in int.
2313
2314 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
2315 (xg_check_special_colors, xg_set_geometry):
2316 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
2317
2318 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
2319 Use esprintf, not sprintf, in case result does not fit in int.
2320
2321 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2322 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
2323 it as a large positive number.
2324 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
2325 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2326
2327 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
2328 in case result does not fit in int.
2329
2330 * print.c (float_to_string): Detect width overflow more reliably.
2331 (print_object): Make sprintf buffer a bit bigger, to avoid potential
2332 buffer overrun. Don't assume list length fits in 'int'. Treat
2333 print length of 0 as 0, not as infinity; to be consistent with other
2334 uses of print length in this function. Don't overflow print length
2335 index. Don't assume hash table size fits in 'long', or that
2336 vectorlike size fits in 'unsigned long'.
2337
2338 * process.c (make_process): Use printmax_t, not int, to format
2339 process-name gensyms.
2340
2341 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
2342
2343 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
2344 to avoid potential buffer overrun.
2345
2346 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
2347 if X resource line is longer than 512 bytes.
2348
2349 * xfns.c (x_window): Make sprintf buffer a bit bigger
2350 to avoid potential buffer overrun.
2351
2352 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
2353
2354 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
2355
2356 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2357
2358 Integer overflow fixes for scrolling, etc.
2359 Without these, Emacs silently mishandles large integers sometimes.
2360 For example, "C-u 4294967297 M-x recenter" was treated as if
2361 it were "C-u 1 M-x recenter" on a typical 64-bit host.
2362
2363 * xdisp.c (try_window_id): Check Emacs fixnum range before
2364 converting to 'int'.
2365
2366 * window.c (window_scroll_line_based, Frecenter):
2367 Check that an Emacs fixnum is in range before assigning it to 'int'.
2368 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
2369 values converted from Emacs fixnums.
2370 (Frecenter): Don't wrap around a line count if it is out of 'int'
2371 range; instead, treat it as an extreme value.
2372 (Fset_window_configuration, compare_window_configurations):
2373 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
2374
2375 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
2376 that can exceed INT_MAX. Check that EMACS_INT value is in range
2377 before assigning it to the (possibly-narrower) index.
2378 (match_limit): Don't assume that a fixnum can fit in 'int'.
2379
2380 * print.c (print_object): Use ptrdiff_t, not int, for index that can
2381 exceed INT_MAX.
2382
2383 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
2384 (Fvertical_motion): Don't wrap around LINES values that don't fit
2385 in 'int'. Instead, treat them as extreme values. This is good
2386 enough for windows, which can't have more than INT_MAX lines anyway.
2387
2388 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
2389
2390 * Require libxml/parser.h to avoid compilation warning.
2391
2392 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
2393
2394 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
2395 since this reportedly can destroy thread storage.
2396
2397 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
2398
2399 * syntax.c (find_defun_start): Update all cache variables if
2400 exiting early (Bug#9401).
2401
2402 2011-08-30 Eli Zaretskii <eliz@gnu.org>
2403
2404 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
2405
2406 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
2407 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
2408 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
2409
2410 * term.c (tty_append_glyph): New function.
2411 (produce_stretch_glyph): Static function and its prototype deleted.
2412
2413 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
2414 Add prototypes.
2415
2416 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
2417
2418 * image.c (parse_image_spec): Check for nonnegative, not for positive,
2419 when checking :margin (Bug#9390).
2420 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
2421 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
2422 so that the name doesn't mislead. All uses changed.
2423
2424 2011-08-28 Johan Bockgård <bojohan@gnu.org>
2425
2426 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
2427 set_tty_hooks.
2428
2429 2011-08-27 Eli Zaretskii <eliz@gnu.org>
2430
2431 * xdisp.c (move_it_to): Don't bail out early when reaching
2432 position beyond to_charpos, if we are scanning backwards.
2433 (move_it_vertically_backward): When DY == 0, make sure we get to
2434 the first character in the line after the newline.
2435
2436 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
2437
2438 * ccl.c: Improve and simplify overflow checking (Bug#9196).
2439 (ccl_driver): Do not generate an out-of-range pointer.
2440 (Fccl_execute_on_string): Remove unnecessary check for
2441 integer overflow, noted by Stefan Monnier in
2442 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
2443 Remove a FIXME that didn't need fixing.
2444 Simplify the newly-introduced buffer reallocation code.
2445
2446 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
2447
2448 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
2449
2450 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
2451
2452 Integer and memory overflow issues (Bug#9196).
2453
2454 * doc.c (get_doc_string): Rework so that
2455 get_doc_string_buffer_size is the actual buffer size, rather than
2456 being 1 less than the actual buffer size; this makes xpalloc more
2457 convenient.
2458
2459 * image.c (x_allocate_bitmap_record, cache_image):
2460 * xselect.c (Fx_register_dnd_atom):
2461 Simplify previous changes by using xpalloc.
2462
2463 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
2464 since either will do and ptrdiff_t is convenient with xpalloc.
2465
2466 * charset.c (charset_table_size)
2467 (struct charset_sort_data.priority): Now ptrdiff_t.
2468 (charset_compare): Don't overflow if priorities differ greatly.
2469 (Fsort_charsets): Don't assume list length fits in int.
2470 Check for size-calculation overflow when allocating sort data.
2471 (syms_of_charset): Allocate an initial charset table that is
2472 just under 64 KiB, to avoid problems with glibc malloc and mmap.
2473
2474 * cmds.c (internal_self_insert): Check for size-calculation overflow.
2475
2476 * composite.h (struct composition.glyph_len): Now int, not unsigned.
2477 The actual value is always <= INT_MAX, and leaving it unsigned made
2478 overflow checking harder.
2479
2480 * dispextern.h (struct glyph_matrix.rows_allocated)
2481 (struct face_cache.size): Now ptrdiff_t, for convenience in use
2482 with xpalloc. The values are still always <= INT_MAX.
2483
2484 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
2485
2486 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
2487 (SAFE_NALLOCA): New macro.
2488
2489 * region-cache.c (struct boundary.pos, find_cache_boundary)
2490 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
2491 (set_cache_region, invalidate_region_cache)
2492 (revalidate_region_cache, know_region_cache, region_cache_forward)
2493 (region_cache_backward, pp_cache):
2494 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
2495 so that ptrdiff_t * can be passed to xpalloc.
2496 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
2497 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
2498 (pp_cache): Don't assume cache_len fits in int.
2499 * region-cache.h: Adjust extern decls to match.
2500
2501 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
2502 EMACS_INT, since either will do, for xpalloc.
2503
2504 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
2505 (xnmalloc, xnrealloc, xpalloc): New functions.
2506
2507 * bidi.c (bidi_shelve_header_size): New constant.
2508 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
2509 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
2510
2511 * bidi.c (bidi_cache_shrink):
2512 * buffer.c (overlays_at, overlays_in, record_overlay_string)
2513 (overlay_strings):
2514 Don't update size of array until after memory allocation succeeds,
2515 because xmalloc/xrealloc may not return.
2516 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
2517 now that we have proper integer overflow checking.
2518 (record_overlay_string, overlay_strings): Catch overflows when
2519 calculating size of overlay_str_buf.
2520
2521 * callproc.c (Fcall_process): Check for size overflow when
2522 calculating size of args2.
2523 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
2524 Normally we prefer signed values, but sticking with ptrdiff_t would
2525 require adding more-complicated checks.
2526
2527 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
2528 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
2529 Redo buffer-overflow calculations to avoid integer overflow.
2530 Add a FIXME comment where memory seems to be over-allocated.
2531
2532 * character.c (Fstring): Check for size-calculation overflow.
2533
2534 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
2535 unnecessary integer overflow. Check for size overflow.
2536 (encode_coding_object): Don't update size until xmalloc succeeds.
2537
2538 * composite.c (get_composition_id): Check for overflow in glyph
2539 length calculations.
2540
2541 Integer and memory overflow fixes for display code.
2542 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
2543 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
2544 (scrolling_window): Check for overflow in size calculations.
2545 (line_draw_cost, realloc_glyph_pool, add_row_entry):
2546 Don't assume glyph table len fits in int.
2547 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
2548 (row_table_size): Now ptrdiff_t, not int.
2549 (scrolling_window): Avoid overflow in size calculations.
2550 Don't update size until allocation succeeds.
2551 * fns.c (concat): Check for overflow in size calculations.
2552 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
2553 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
2554 (NEXT_ALMOST_PRIME_LIMIT): New constant.
2555
2556 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
2557 (get_doc_string): Check for size calculation overflow.
2558 Don't update size until allocation succeeds.
2559 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
2560 EMACS_INT, where ptrdiff_t will do.
2561 (Fsubstitute_command_keys): Check for string overflow.
2562
2563 * editfns.c (set_time_zone_rule): Don't assume environment length
2564 fits in int.
2565 (message_length): Now ptrdiff_t, not int.
2566 (Fmessage_box): Don't update size until allocation succeeds.
2567 Don't assume message length fits in int.
2568 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
2569
2570 * emacs.c (main): Do not reallocate argv, since there is a null at
2571 the end that can be overwritten, and this way there's no need to
2572 worry about size-calculation overflow.
2573 (sort_args): Check for size-calculation overflow.
2574
2575 * eval.c (init_eval_once, grow_specpdl): Don't update size until
2576 alloc succeeds.

2585 This is for the members text_lines, text_cols, total_lines, total_cols,
2586 where the system imposes an 'int' limit.
2587
2588 * fringe.c (Fdefine_fringe_bitmap):

2689 * xfns.c (x_encode_text, x_set_name_internal)
2690 (Fx_change_window_property): Use ptrdiff_t, not int, to count

2695 (xg_select): Check for size calculation overflow.
2696 Don't update size until alloc done.
2697
2698 * xrdb.c (get_environ_db): Don't assume path length fits in int,

2700
2701 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
2702 (X_LONG_MIN): New macros.
2703 Use them to make the following changes clearer.
2704 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
2705 This change doesn't affect the value now, but it may help remind
2706 future maintainers not to raise the value too much later.
2707 (SELECTION_QUANTUM): Remove, replacing with ...
2708 (selection_quantum): ... new function, which avoids overflow.
2709 All uses changed.
2710 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
2711 assumption that selection length fits in 'int'.
2712 (x_reply_selection_request, x_handle_selection_request)

2719 Redo calculations to avoid overflow.
2720 (x_reply_selection_request): When sending hint, ceiling it at

2728 Don't store size until memory allocation succeeds.
2729 (x_get_window_property): Plug memory leak on memory exhaustion.
2730 Don't double-block input; malloc is safe here. Don't assume 2**34
2731 - 4 fits in unsigned long. Add an xassert to check
2732 XGetWindowProperty overflow. Be more careful about overflow
2733 calculations, and distinguish size from memory overflow better.
2734 (receive_incremental_selection): When tracing, don't assume
2735 unsigned int is less than INT_MAX.
2736 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

2739 in the range -65535 through -1 fit in an X unsigned short.
2740 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
2741 result parameters unless successful. Rely on cons_to_unsigned
2742 to report problems with elements; the old code wasn't right anyway.

2777 * lisp.h (hash_lookup, hash_put):
2778 * minibuf.c (Ftest_completion):
2779 Use ptrdiff_t for hash table indexes, not int (which is too
2780 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
2781 32-bit --with-wide-int hosts).
2782
2783 * charset.c (Fdefine_charset_internal): Check for integer overflow.
2784 Add a FIXME comment about memory leaks.
2785 (syms_of_charset): Don't assume xmalloc returns.

2813 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
2814 (x_send_scroll_bar_event): Likewise. Check that the size does not
2815 exceed limits imposed by XClientMessageEvent, as well as the usual
2816 ptrdiff_t and size_t limits.
2817
2818 * keyboard.c: Overflow, signedness and related fixes.
2819 (make_lispy_movement): Use same integer type in forward decl
2820 that is used in the definition.
2821 (read_key_sequence, keyremap_step):
2822 Change bufsize argument back to int, undoing my 2011-03-30 change.
2823 We prefer signed types, and int is wide enough here.
2824 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
2825 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
2826 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
2827 length, not size_t. Use ptrdiff_t for index, not int.
2828 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
2829 possibility of integer overflow.

2853 (lookup_image): Remove unnecessary tests.
2854 (xbm_image_p): Locals are now of int, not EMACS_INT,
2855 since parse_image_check makes sure they fit into int.
2856 (png_load, gif_load, svg_load_image):
2857 Prefer int to unsigned where either will do.
2858 (tiff_handler): New function, combining the cores of the
2859 old tiff_error_handler and tiff_warning_handler.
2860 This function is rewritten to use vsnprintf and thereby avoid
2861 stack buffer overflows. It uses only the features of vsnprintf
2862 that are common to both POSIX and native Microsoft.
2863 (tiff_error_handler, tiff_warning_handler): Use it.
2864 (tiff_load, gif_load, imagemagick_load_image):
2865 Don't assume :index value fits in 'int'.
2866 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
2867 (imagemagick_load_image): Check that crop parameters fit into
2868 the integer types that MagickCropImage accepts. Don't assume
2869 Vimagemagick_render_type has a nonnegative value. Don't assume
2870 size_t fits in 'long'.
2871 (gs_load): Use printmax_t to print the widest integers possible.

2884 handle_single_display_spec, not just 1 or zero.
2885 (handle_single_display_spec): If the display spec is of the form
2886 `(space ...)', and specifies display in the text area, return 2
2887 rather than 1.
2888 (try_cursor_movement): Check for the need to scroll more
2889 accurately, and prefer exact match for point under bidi.
2890 Don't advance `row' beyond the last row of the window.

2911 positioning on the newline at EOL of R2L text within L2R
2912 paragraph, and vice versa.
2913 (try_cursor_movement): Check continued rows, in addition to
2914 continuation rows. Fixes unwarranted scroll when point enters a
2915 continued line of R2L text within an L2R paragraph, or vice versa.
2916 (cursor_row_p): Consider the case of point being equal to
2917 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
2918 from the end of a short line to the beginning of a continued line
2919 of R2L text within L2R paragraph.
2920 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

2942
2943 * xdisp.c (redisplay_window): When computing centering_position,
2944 account for the height of the header line. (Bug#8874)
2945
2946 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
2947 instead of CHAR_TO_BYTE. Fixes a crash when a completion
2948 candidate is selected by the mouse, and that candidate has a
2949 composed character under the mouse.
2950
2951 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
2952 coordinates reported by pos-visible-in-window-p for a composed
2953 character in column zero.

2960
2961 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
2962 consider it a hit if to_charpos is anywhere in the range of the
2963 composed buffer positions.
2964
2965 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
2966
2967 * image.c (gif_load): Don't assume that each subimage has the same
2968 dimensions as the base image. Handle disposal method that is
2969 "undefined" by the gif spec (Bug#9335).
2970
2971 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

2993 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
2994 members before the level stack, so they would be saved and
2995 restored when copying iterator state. Fixes incorrect reordering
2996 around TABs covered by display properties.
2997
2998 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

3009
3010 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
3011 has no `load' handler, try opening the file locally. (Bug#9311)
3012
3013 2011-08-16 Ken Brown <kbrown@cornell.edu>
3014
3015 * gmalloc.c: Expand comment.
3016
3017 2011-08-16 Eli Zaretskii <eliz@gnu.org>
3018
3019 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
3020 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
3021
3022 2011-08-16 Ken Brown <kbrown@cornell.edu>
3023
3024 Fix memory allocation problems in Cygwin build (Bug#9273).

3056 (bidi_initialize): Use uniprop_table instead of including
3057 biditype.h and bidimirror.h.
3058
3059 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
3060 coordinates of the iterator when restoring from ppos_it.
3061 (Bug#9296)
3062
3063 2011-08-14 Kenichi Handa <handa@m17n.org>
3064
3065 * process.c (create_process): Call setup_process_coding_systems
3066 after the pid of the process is set to -1 (Bug#8162).
3067
3068 2011-08-14 Eli Zaretskii <eliz@gnu.org>
3069
3070 * xdisp.c (move_it_in_display_line_to): Don't invoke
3071 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
3072 ppos_it. Fixes vertical cursor motion when line beginning is
3073 covered by an image. (Bug#9296)
3074
3075 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
3076
3077 * nsterm.h (ns_run_ascript): Declare.

3081 (ns_run_ascript): New function.
3082 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
3083 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
3084 the event loop. Get status from as_status (Bug#7276).
3085
3086 * nsterm.m (sendEvent): If event is NSApplicationDefined and
3087 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
3088 the event loop (Bug#7276).
3089
3090 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
3091
3092 * gnutls.c (QCgnutls_bootprop_priority)

3112
3113 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
3114 (Fnetwork_interface_list): Allocate in increments of bytes instead
3115 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
3116 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
3117 sockaddr.
3118 (struct ifflag_def): notrailers is smart on OSX.
3119 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
3120 Get hardware address with getifaddrs if available.
3121
3122 2011-08-12 Eli Zaretskii <eliz@gnu.org>
3123
3124 * xdisp.c (iterate_out_of_display_property): xassert that
3125 IT->position is set to within IT->object's boundaries. Break from
3126 the loop as soon as EOB is reached; avoids infloops in redisplay
3127 when IT->position is set up wrongly due to some bug.
3128 Set IT->current to match the bidi iterator unconditionally.
3129 (push_display_prop): Allow GET_FROM_STRING as IT->method on
3130 entry. Force push_it to save on the stack the current
3131 buffer/string position, to be restored by pop_it. Fix flags in
3132 the iterator structure wrt the object coming from a display
3133 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
3134 properties. (Bug#9284)
3135
3136 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
3137
3138 * fontset.c (fontset_get_font_group): Add proper type checks.

3144 and LC_VERSION_MIN_MACOSX.
3145 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
3146 (dump_it) [LC_FUNCTION_STARTS]: Use it.
3147
3148 2011-08-08 Eli Zaretskii <eliz@gnu.org>
3149
3150 * xdisp.c (forward_to_next_line_start): Allow to use the
3151 no-display-properties-and-no-overlays under bidi display.
3152 Set disp_pos in the bidi iterator to avoid searches for display
3153 properties and overlays.
3154

3161 the font entity extracted from the cache (Bug#8109).
3162
3163 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
3164
3165 * composite.c (autocmp_chars): Don't reset point. That is done by
3166 restore_point_unwind (Bug#5984).
3167
3168 2011-08-07 Juri Linkov <juri@jurta.org>
3169
3170 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
3171 to show the arg `TIME' instead of `TIMEVAL'.
3172
3173 2011-08-06 Eli Zaretskii <eliz@gnu.org>
3174
3175 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
3176 display property strides EOL and includes a newline, as in
3177 longlines-mode. (Bug#9254)
3178 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
3179 word-wrap under bidirectional display. (Bug#9224)
3180
3181 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
3182 is non-zero, even if the data buffer is NULL. Fixes a crash in
3183 vertical-motion with longlines-mode. (Bug#9254)
3184
3185 2011-08-05 Eli Zaretskii <eliz@gnu.org>
3186
3187 * bidi.c <bidi_cache_total_alloc>: Now static.
3188 (bidi_initialize): Initialize bidi_cache_total_alloc.
3189
3190 * xdisp.c (display_line): Release buffer allocated for shelved bidi
3191 cache. (Bug#9221)
3192
3193 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
3194 amount allocated this far in `bidi_cache_total_alloc'.
3195 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
3196 non-zero, only free the data buffer without restoring the cache
3197 contents. All callers changed.
3198
3199 * dispextern.h (bidi_unshelve_cache): Update prototype.
3200
3201 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
3202 (move_it_in_display_line, move_it_to)
3203 (move_it_vertically_backward, move_it_by_lines): Replace the call
3204 to xfree to an equivalent call to bidi_unshelve_cache.
3205 (move_it_in_display_line_to): Fix logic of returning
3206 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
3207
3208 2011-08-05 Eli Zaretskii <eliz@gnu.org>
3209
3210 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
3211 came from a string character with a `cursor' property. (Bug#9229)
3212
3213 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
3214
3215 * Makefile.in (LIB_PTHREAD): New variable.
3216 (LIBES): Add LIB_PTHREAD (Bug#9216).
3217
3218 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
3219 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
3220
3221 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
3222
3223 * regex.c (re_iswctype): Remove some redundant boolean conversions.
3224

3227 * xterm.c (x_find_topmost_parent): New function.
3228 (x_set_frame_alpha): Find topmost parent window with
3229 x_find_topmost_parent and set the property there also (bug#9181).

3231
3232 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
3233
3234 * callproc.c (Fcall_process): Avoid vfork clobbering
3235 the local vars buffer, coding_systems, current_dir.
3236
3237 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
3238
3239 * keymap.c (Fmake_composed_keymap): Move to subr.el.
3240
3241 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
3242
3243 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
3244 so that it is not optimized away.
3245
3246 * xdisp.c (compute_display_string_pos): Remove unused local.
3247
3248 2011-08-02 Eli Zaretskii <eliz@gnu.org>
3249
3250 Fix slow cursor motion and scrolling in large buffers with
3251 selective display, like Org Mode buffers. (Bug#9218)
3252
3253 * dispextern.h (struct bidi_it): New member disp_prop_p.
3254
3255 * xdisp.c: Remove one-slot cache of display string positions.
3256 (compute_display_string_pos): Accept an additional argument
3257 DISP_PROP_P; callers changed. Scan at most 5K characters forward
3258 for a display string or property. If found, set DISP_PROP_P
3259 non-zero.
3260
3261 * bidi.c (bidi_fetch_char): Accept an additional argument
3262 DISP_PROP_P, and pass it to compute_display_string_pos.
3263 Only handle text covered by a display string if DISP_PROP_P is returned
3264 non-zero. All callers of bidi_fetch_char changed.
3265
3266 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
3267
3268 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
3269
3270 2010-12-03 Don March <don@ohspite.net>
3271
3272 * keymap.c (Fdefine_key): Fix non-prefix key error message when
3273 last character M-[char] is translated to ESC [char] (bug#7541).
3274
3275 2011-08-02 Kenichi Handa <handa@m17n.org>
3276
3277 * lisp.h (uniprop_table): Extern it.
3278
3279 * chartab.c (uniprop_table): Make it non-static.
3280
3281 2011-08-01 Eli Zaretskii <eliz@gnu.org>
3282
3283 * xdisp.c (forward_to_next_line_start): Accept additional argument
3284 BIDI_IT_PREV, and store into it the state of the bidi iterator had
3285 on the newline.
3286 (reseat_at_next_visible_line_start): Use the bidi iterator state
3287 returned by forward_to_next_line_start to restore the state of
3288 it->bidi_it after backing up to previous newline. (Bug#9212)
3289
3290 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
3291
3292 * regex.c (re_comp): Protoize.
3293 (re_exec): Fix return type.
3294 (regexec): Fix type of `ret'. (Bug#9203)
3295
3296 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3297
3298 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
3299 This is needed if max-image-size is a floating-point number.
3300
3301 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3302
3303 * print.c (print_object): Print empty symbol as ##.
3304
3305 * lread.c (read1): Read ## as empty symbol.
3306
3307 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3308
3309 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
3310 setting frame foreground color (Bug#9175).
3311 (x_set_background_color): Likewise.
3312
3313 * nsmenu.m (-setText): Size tooltip dimensions precisely to
3314 contents (Bug#9176).
3315 (EmacsTooltip -init): Remove bezels and add shadows to
3316 tooltip windows.
3317
3318 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
3319 or scroll bar (Bug#8470).
3320
3321 * nsfont.m (nsfont_open): Remove assignment to voffset and
3322 unnecessary vars hshink, expand, hd, full_height, min_height.
3323 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
3324
3325 * nsterm.h (nsfont_info): Remove voffset field.
3326
3327 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3328
3329 Implement strike-through and overline on NextStep (Bug#8863).
3330
3331 * nsfont.m (nsfont_open): Use underline position provided by font,
3332 instead of hard-coded value of 2.
3333 (nsfont_draw): Call ns_draw_text_decoration instead.
3334
3335 * nsterm.h: Add declaration for ns_draw_text_decoration.
3336
3337 * nsterm.m (ns_draw_text_decoration): New function for drawing
3338 underline, overline, and strike-through.

3346 default.
3347
3348 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3349
3350 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
3351 Without this fix, if a signal arrives just after memory fills up,
3352 'malloc' might be invoked reentrantly.
3353
3354 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
3355 In other words, assume that every image size is allowed, on non-X
3356 hosts. This assumption is probably wrong, but it lets Emacs compile.
3357
3358 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3359
3360 * regex.c (re_iswctype): Convert return values to boolean.
3361
3362 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
3363
3364 * xdisp.c (compute_display_string_pos): Don't use cached display
3365 string position if the buffer had its restriction changed.
3366 (Bug#9184)
3367
3368 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3369
3370 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3371
3372 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3373
3374 Integer signedness and overflow and related fixes. (Bug#9079)
3375
3376 * bidi.c: Integer size and overflow fixes.
3377 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
3378 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
3379 (bidi_cache_find_level_change, bidi_cache_ensure_space)
3380 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
3381 (bidi_find_other_level_edge):
3382 Use ptrdiff_t instead of EMACS_INT where either will do.
3383 This works better on 32-bit hosts configured --with-wide-int.
3384 (bidi_cache_ensure_space): Check for size-calculation overflow.
3385 Use % rather than repeated addition, for better worst-case speed.
3386 Don't set bidi_cache_size until after xrealloc returns, because it
3387 might not return.
3388 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
3389 (bidi_cache_ensure_space): Also check that the bidi cache size
3390 does not exceed that of the largest Lisp string or buffer. See Eli
3391 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
3392
3393 * alloc.c (__malloc_size_t): Remove.
3394 All uses replaced by size_t. See Andreas Schwab's note
3395 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
3396
3397 * image.c: Improve checking for integer overflow.
3398 (check_image_size): Assume that f is nonnull, since
3399 it is always nonnull in practice. This is one less thing to
3400 worry about when checking for integer overflow later.
3401 (x_check_image_size): New function, which checks for integer
3402 overflow issues inside X.
3403 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
3404 This removes the need for a memory_full check.
3405 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
3406 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
3407 (xbm_read_bitmap_data): Change locals back to 'int', since
3408 their values must fit in 'int'.
3409 (xpm_load_image, png_load, tiff_load):
3410 Invoke x_create_x_image_and_pixmap earlier,
3411 to avoid much needless work if the image is too large.
3412 (tiff_load): Treat overly large images as if
3413 x_create_x_image_and_pixmap failed, not as malloc failures.
3414 (gs_load): Use x_check_image_size.
3415
3416 * gtkutil.c: Omit integer casts.
3417 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
3418 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
3419
3420 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
3421
3422 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
3423 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
3424 would wrongly return t on a 64-bit host.
3425
3426 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
3427 The plain *_OVERFLOW macros run afoul of GCC bug 49705
3428 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
3429 and therefore cause GCC to emit a bogus diagnostic in some cases.
3430
3431 * image.c: Integer signedness and overflow and related fixes.
3432 This is not an exhaustive set of fixes, but it's time to
3433 record what I've got.
3434 (lookup_pixel_color, check_image_size): Remove redundant decls.
3435 (check_image_size): Don't assume that arbitrary EMACS_INT values
3436 fit in 'int', or that arbitrary 'double' values fit in 'int'.
3437 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
3438 (tiff_load, imagemagick_load_image):
3439 Check for overflow in size calculations.
3440 (x_create_x_image_and_pixmap): Remove unnecessary test for
3441 xmalloc returning NULL; that can't happen.
3442 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
3443 (xpm_color_bucket): Use better integer hashing function.
3444 (xpm_cache_color): Don't possibly over-allocate memory.
3445 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
3446 (gif_memory_source):
3447 Use ptrdiff_t, not int or size_t, to record sizes.
3448 (png_load): Don't assume values greater than 2**31 fit in 'int'.
3449 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
3450 either works, as we prefer signed integers.
3451 (tiff_read_from_memory, tiff_write_from_memory):
3452 Return tsize_t, not size_t, since that's what the TIFF API wants.
3453 (tiff_read_from_memory): Don't fail simply because the read would
3454 go past EOF; instead, return a short read.
3455 (tiff_load): Omit no-longer-needed casts.
3456 (Fimagemagick_types): Don't assume size fits into 'int'.
3457
3458 Improve hashing quality when configured --with-wide-int.
3459 * fns.c (hash_string): New function, taken from sxhash_string.
3460 Do not discard information about ASCII character case; this
3461 discarding is no longer needed.
3462 (sxhash-string): Use it. Change sig to match it. Caller changed.
3463 * lisp.h: Declare it.
3464 * lread.c (hash_string): Remove, since we now use fns.c's version.
3465 The fns.c version returns a wider integer if --with-wide-int is
3466 specified, so this should help the quality of the hashing a bit.
3467
3468 * emacs.c: Integer overflow minor fix.
3469 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
3470 Define only if GNU_LINUX.
3471 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
3472
3473 * dispnew.c: Integer signedness and overflow fixes.
3474 Remove unnecessary forward decls, that were a maintenance hassle.
3475 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
3476 All uses changed.
3477 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
3478 (scrolling_window): Use ptrdiff_t, not int, for byte count.
3479 (prepare_desired_row, line_draw_cost):
3480 Use int, not unsigned, where either works.
3481 (save_current_matrix, restore_current_matrix):
3482 Use ptrdiff_t, not size_t, where either works.
3483 (init_display): Check for overflow more accurately, and without
3484 relying on undefined behavior.
3485
3486 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
3487 Remove, replacing with the new symbols in lisp.h. All uses changed.
3488 * fileio.c (make_temp_name):
3489 * filelock.c (lock_file_1, lock_file):
3490 * xdisp.c (message_dolog):
3491 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
3492 Use pMd etc. instead.
3493 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
3494 replacing the pWIDE etc. symbols removed from editfns.c.
3495
3496 * keyboard.h (num_input_events): Now uintmax_t.
3497 This is (very slightly) less likely to mess up due to wraparound.
3498 All uses changed.
3499
3500 * buffer.c: Integer signedness fixes.
3501 (alloc_buffer_text, enlarge_buffer_text):
3502 Use ptrdiff_t rather than size_t when either will do, as we prefer
3503 signed integers.
3504
3505 * alloc.c: Integer signedness and overflow fixes.
3506 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
3507 (__malloc_size_t): Default to size_t, not to int.
3508 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
3509 (Fgarbage_collect, mark_object_loop_halt, mark_object):
3510 Prefer ptrdiff_t to size_t when either would do, as we prefer
3511 signed integers.
3512 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
3513 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
3514 Now const. Initialize with values that are in range even if char
3515 is signed.
3516 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
3517 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
3518 These functions do the right thing with sizes > 2**32.
3519 (check_depth): Now ptrdiff_t, not int.
3520 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
3521 Adjust to new way of storing sizes. Check for size overflow bugs
3522 in rest of code.
3523 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
3524 slightly wrong anyway, as it missed one instance of
3525 XMALLOC_OVERRUN_CHECK_OVERHEAD.
3526 (refill_memory_reserve): Omit needless cast to size_t.
3527 (mark_object_loop_halt): Mark as externally visible.
3528
3529 * xselect.c: Integer signedness and overflow fixes.
3530 (Fx_register_dnd_atom, x_handle_dnd_message):
3531 Use ptrdiff_t, not size_t, since we prefer signed.
3532 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
3533 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
3534 x_dnd_atoms_size and x_dnd_atoms_length.
3535
3536 * doprnt.c: Prefer signed to unsigned when either works.
3537 * eval.c (verror):
3538 * doprnt.c (doprnt):
3539 * lisp.h (doprnt):
3540 * xdisp.c (vmessage):
3541 Use ptrdiff_t, not size_t, when using or implementing doprnt,
3542 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
3543 prefer signed arithmetic to avoid comparison confusion.
3544 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
3545 but is a bit tricky.
3546
3547 Assume freestanding C89 headers, string.h, stdlib.h.
3548 * data.c, doprnt.c, floatfns.c, print.c:
3549 Include float.h unconditionally.
3550 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
3551 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
3552 * regex.c: Likewise for stddef.h, string.h.
3553 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
3554 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
3555 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
3556 (STDC_HEADERS): Remove obsolete defines.
3557 * sysdep.c: Include limits.h unconditionally.
3558
3559 Assume support for memcmp, memcpy, memmove, memset.
3560 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
3561 * regex.c (memcmp, memcpy):
3562 Remove; we assume C89 now.
3563
3564 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
3565 (__malloc_safe_bcopy): Remove; no longer needed.
3566
3567 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
3568 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
3569 well either way, and we prefer signed to unsigned.
3570
3571 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
3572
3573 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
3574 closes the connection while we're reading (bug#9182).
3575
3576 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
3577
3578 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
3579 are specified (Bug#9168).
3580
3581 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
3582
3583 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
3584 Found by GCC static checking and --with-wide-int on a 32-bit host.
3585
3586 2011-07-25 Eli Zaretskii <eliz@gnu.org>
3587
3588 * xdisp.c (compute_display_string_pos): Fix logic of caching
3589 previous display string position. Initialize cached_prev_pos to
3590 -1. Fixes slow-down at the beginning of a buffer.
3591
3592 2011-07-24 Eli Zaretskii <eliz@gnu.org>
3593
3594 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
3595 for attrs[LFACE_FONTSET_INDEX].
3596
3597 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
3598
3599 * xml.c (parse_region): Remove unused local
3600 that was recently introduced.
3601
3602 2011-07-23 Eli Zaretskii <eliz@gnu.org>
3603
3604 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
3605 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
3606
3607 * xdisp.c (move_it_in_display_line_to): Record the best matching
3608 position for TO_CHARPOS while scanning the line, and restore it on
3609 exit if none of the characters scanned was an exact match.
3610 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
3611 when exact match is impossible due to invisible text, and the
3612 lines are truncated.
3613
3614 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
3615
3616 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
3617 for OSX >= 10.7.
3618
3619 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3620
3621 Fix a significant slow-down of cursor motion with C-n, C-p,
3622 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
3623 auto-repeat under bidi redisplay in fontified buffers.
3624 * xdisp.c (compute_stop_pos_backwards): New function.
3625 (next_element_from_buffer): Call compute_stop_pos_backwards to
3626 find a suitable prev_stop when we find ourselves before
3627 base_level_stop.
3628 (reseat): Don't look for prev_stop, as that could mean a very long
3629 run.
3630 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
3631 <cached_disp_overlay_modiff>: Cache for last found display string
3632 position.
3633 (compute_display_string_pos): Return the cached position if asked
3634 about the same buffer in the same area of character positions, and
3635 the buffer wasn't changed since the time the display string
3636 position was cached.
3637
3638 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3639
3640 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
3641 is an integer, which is important for empty lines. (Bug#9149)
3642
3643 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
3644
3645 * frame.c (Fmodify_frame_parameters): In tty case, update the
3646 default face if necessary (Bug#4238).
3647
3648 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
3649
3650 * editfns.c (Fstring_to_char): No need to explain what a character
3651 is in the docstring (Bug#6576).
3652
3653 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3654
3655 * xml.c (parse_region): Make sure we always return a tree.
3656
3657 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
3658
3659 * xml.c (parse_region): If a document contains only comments,
3660 return that, too.
3661
3662 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3663
3664 * xml.c (make_dom): Return comments, too.
3665
3666 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
3667
3668 Port to OpenBSD.
3669 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
3670 and the surrounding thread.
3671 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
3672 rather than fgets, and retry after EINTR. Otherwise, 'emacs
3673 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
3674 timer goes off.
3675 * s/openbsd.h (BROKEN_SIGIO): Define.
3676 * unexelf.c (unexec) [__OpenBSD__]:
3677 Don't update the .mdebug section of the Alpha COFF symbol table.
3678
3679 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
3680
3681 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
3682 (bug#8460).
3683
3684 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
3685
3686 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
3687 This fixes some race conditions on the permissions of any newly
3688 created file.
3689
3690 * alloc.c (valid_pointer_p): Use pipe, not open.
3691 This fixes some permissions issues when debugging.
3692
3693 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
3694 If fchown fails to set both uid and gid, try to set just gid,
3695 as that is sometimes allowed. Adjust the file's mode to eliminate
3696 setuid or setgid bits that are inappropriate if fchown fails.
3697
3698 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3699
3700 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
3701 to compare Lisp_Objects.
3702 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
3703 global_gnutls_log_level, don't mistake it for a Lisp_Object.
3704 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
3705
3706 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
3707
3708 * lread.c (read_integer): Unread even EOF character.
3709 (read1): Likewise. Properly record start position of symbol.
3710
3711 * lread.c (read1): Read `#:' as empty uninterned symbol if no
3712 symbol character follows.
3713
3714 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
3715
3716 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
3717 This works around a problem with the previous change to Fcopy_file.
3718 Recent glibc declares fchown with __attribute__((warn_unused_result)),
3719 and without this change, GCC might complain about discarding
3720 fchown's return value.
3721
3722 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
3723
3724 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
3725
3726 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
3727
3728 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
3729
3730 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
3731
3732 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
3733 it's used from the C level.
3734
3735 * process.c: Use the same condition for POLL_FOR_INPUT in both
3736 keyboard.c and process.c (bug#1858).
3737
3738 2011-07-09 Lawrence Mitchell <wence@gmx.li>
3739
3740 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
3741 (Fgnutls_boot): Use it.
3742
3743 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
3744
3745 * doc.c (Fsubstitute_command_keys): Revert last change.
3746
3747 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
3748
3749 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
3750 quotes the next character, and doesn't affect other longer
3751 sequences (bug#8935).
3752
3753 * lread.c (syms_of_lread): Clarify that is isn't only
3754 `eval-buffer' and `eval-defun' that's affected by
3755 `lexical-binding' (bug#8460).
3756
3757 2011-07-15 Eli Zaretskii <eliz@gnu.org>
3758
3759 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
3760 bidi redisplay when a line includes both an image and is truncated.
3761
3762 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
3763
3764 Fix minor problems found by static checking.
3765 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
3766 (elsz): Now a signed constant, not a size_t var. We prefer signed
3767 types to unsigned, to avoid integer comparison confusion. Without
3768 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
3769 "cannot optimize loop, the loop counter may overflow", a symptom
3770 of the confusion.
3771 * indent.c (Fvertical_motion): Mark locals as initialized.
3772 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
3773
3774 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
3775
3776 * search.c (Fre_search_backward): Mention `case-fold-search' in
3777 all the re_search_* functions (bug#8138).
3778
3779 * keyboard.c (Fopen_dribble_file): Document when the file is
3780 closed (bug#8056).
3781
3782 2011-07-14 Eli Zaretskii <eliz@gnu.org>
3783
3784 * bidi.c (bidi_dump_cached_states): Fix format of displaying
3785 bidi_cache_idx.
3786
3787 Support bidi reordering of display and overlay strings.
3788 * xdisp.c (compute_display_string_pos)
3789 (compute_display_string_end): Accept additional argument STRING.
3790 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
3791 (reseat_to_string): Initialize bidi_it->string.s and
3792 bidi_it->string.schars.
3793 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
3794 NULL (avoids a crash in bidi_paragraph_init).
3795 Initialize itb.string.lstring.
3796 (init_iterator): Call bidi_init_it only of a valid
3797 buffer position was specified. Initialize paragraph_embedding to
3798 L2R.
3799 (reseat_to_string): Initialize the bidi iterator.
3800 (display_string): If we need to ignore text properties of
3801 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
3802 original value of -1 will not work with bidi.)
3803 (compute_display_string_pos): First arg is now struct
3804 `text_pos *'; all callers changed. Support display properties on
3805 Lisp strings.
3806 (compute_display_string_end): Support display properties on Lisp
3807 strings.
3808 (init_iterator, reseat_1, reseat_to_string): Initialize the
3809 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
3810 when iterating on a string not from display properties).
3811 (compute_display_string_pos, compute_display_string_end):
3812 Fix calculation of the object to scan. Fixes an error when using
3813 arrow keys.
3814 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
3815 base_level_stop; instead, set base_level_stop to BEGV.
3816 Fixes crashes in vertical-motion.
3817 (next_element_from_buffer): Improve commentary for when
3818 the iterator is before prev_stop.
3819 (init_iterator): Initialize bidi_p from the default value of
3820 bidi-display-reordering, not from buffer-local value. Use the
3821 buffer-local value only if initializing for buffer iteration.
3822 (handle_invisible_prop): Support invisible properties on strings
3823 that are being bidi-reordered.
3824 (set_iterator_to_next): Support bidi reordering of C strings and
3825 Lisp strings.
3826 (next_element_from_string): Support bidi reordering of Lisp
3827 strings.
3828 (handle_stop_backwards): Support Lisp strings as well.
3829 (display_string): Support display of R2L glyph rows.

4295 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
4296 (clone_per_buffer_values): Don't assume that

4301 New macros, used in the buffer.c change.

4335 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
4336
4337 Random fixes. E.g., (random) never returned negative values.
4338 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
4339 subseconds part to the entropy, as that's a bit more random.
4340 Prefer signed to unsigned, since the signedness doesn't matter and
4341 in general we prefer signed. When given a limit, use a
4342 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
4343 latter isn't right if USE_2_TAGS_FOR_INTS.
4344 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
4345 not 0..VALMASK. Don't discard "excess" bits that random () returns.

4354
4355 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
4356
4357 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
4358 This is more efficient than Ffile_directory_p and avoids a minor race.
4359
4360 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
4361
4362 * buffer.c (Foverlay_put): Say what the return value is
4363 (bug#7835).
4364

4383 (syms_of_gnutls): Remove duplicate DEFSYM for
4384 Qgnutls_bootprop_verify_hostname_error, an error for
4385 Qgnutls_bootprop_verify_error (which is no longer used).
4386
4387 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
4388 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
4389 Also (re)move comments that are misplaced or no longer relevant.

4445 (Fcopy_keymap): Handle embedded parents.
4446 (Fcommand_remapping, define_as_prefix): Simplify.

4489
4490 * eval.c (struct backtrace): Simplify and port the data structure.
4491 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
4492 signed bit field, as this assumption is not portable and it makes
4493 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
4494 "char debug_on_exit : 1" as this is not portable either; instead,
4495 use the portable "unsigned int debug_on_exit : 1". Remove unused
4496 member evalargs. Remove obsolete comments about cc bombing out.
4497
4498 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

4541 the overlay's window property doesn't match the current window.
4542
4543 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
4544 (Fwindow_hchild): Rename to Fwindow_left_child.

4566 (emacs_fixed_new): Set priv->f to argument.
4567 (emacs_fixed_get_preferred_width)
4568 (emacs_fixed_get_preferred_height): Use min_width/height from
4569 frames size_hint to set minimum and natural (Bug#8919).

4585
4586 * process.c (wait_reading_process_output): Bypass select if

4653 * xsettings.c (syms_of_xsettings):
4654 * xterm.c (syms_of_xterm): Use DEFSYM.
4655
4656 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
4657
4658 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
4659
4660 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
4661
4662 Integer and buffer overflow fixes (Bug#8873).
4663
4664 * print.c (printchar, strout): Check for string overflow.
4665 (PRINTPREPARE, printchar, strout):
4666 Don't set size unless allocation succeeds.
4667
4668 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
4669 for sizes. Check for string overflow more accurately.
4670 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
4671
4672 * macros.c: Integer and buffer overflow fixes.
4673 * keyboard.h (struct keyboard.kbd_macro_bufsize):
4674 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
4675 Use ptrdiff_t, not int, for sizes.
4676 Don't increment bufsize until after realloc succeeds.
4677 Check for size-calculation overflow.
4678 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
4679
4680 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
4681
4682 * lread.c: Integer overflow fixes.
4683 (read_integer): Radix is now EMACS_INT, not int,
4684 to improve quality of diagnostics for out-of-range radices.
4685 Calculate buffer size correctly for out-of-range radices.
4686 (read1): Check for integer overflow in radices, and in
4687 read-circle numbers.
4688 (read_escape): Avoid int overflow.
4689 (Fload, openp, read_buffer_size, read1)
4690 (substitute_object_recurse, read_vector, read_list, map_obarray):
4691 Use ptrdiff_t, not int, for sizes.
4692 (read1): Use EMACS_INT, not int, for sizes.
4693 Check for size overflow.
4694
4695 * image.c (cache_image): Check for size arithmetic overflow.
4696
4697 * lread.c: Integer overflow issues.
4698 (saved_doc_string_size, saved_doc_string_length)
4699 (prev_saved_doc_string_size, prev_saved_doc_string_length):
4700 Now ptrdiff_t, not int.

4705
4706 2011-06-22 Leo Liu <sdl.web@gmail.com>
4707
4708 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
4709 Move to minibuffer.el.
4710
4711 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
4712
4713 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
4714 The following patches are for when GLYPH_DEBUG && !XASSERT.
4715 * dispextern.h (trace_redisplay_p, dump_glyph_string):
4716 * dispnew.c (flush_stdout):
4717 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
4718 Mark as externally visible.
4719 * dispnew.c (check_window_matrix_pointers): Now static.
4720 * dispnew.c (window_to_frame_vpos):
4721 * xfns.c (unwind_create_frame):
4722 * xterm.c (x_check_font): Remove unused local.
4723 * scroll.c (CHECK_BOUNDS):
4724 * xfaces.c (cache_fache): Rename local to avoid shadowing.
4725 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
4726 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
4727 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
4728 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
4729 Now static.
4730 (debug_method_add): Use va_list and vsprintf rather than relying
4731 on undefined behavior with wrong number of arguments.
4732 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
4733 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
4734 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
4735 since we're not interested in debugging glyphs with old libraries.
4736 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
4737 GCC 4.6.0's static checking.
4738
4739 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
4740
4741 Integer overflow and signedness fixes (Bug#8873).

4750 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
4751 (x_create_bitmap_from_xpm_data):
4752 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
4753 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
4754 (.bitmaps_last):
4755 * xfaces.c (load_pixmap):
4756 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
4757 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
4758 (.bitmaps_last, struct x_output.icon_bitmap):
4759 Use ptrdiff_t, not int, for bitmap indexes.
4760 (x_allocate_bitmap_record): Check for size overflow.
4761 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
4762
4763 Use ptrdiff_t, not int, for overlay counts.
4764 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
4765 * editfns.c (overlays_around, get_pos_property):
4766 * textprop.c (get_char_property_and_overlay):
4767 * xdisp.c (next_overlay_change, note_mouse_highlight):
4768 * xfaces.c (face_at_buffer_position):
4769 * buffer.c (OVERLAY_COUNT_MAX): New macro.
4770 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
4771 (Fnext_overlay_change, Fprevious_overlay_change)
4772 (mouse_face_overlay_overlaps, Foverlays_in):
4773 Use ptrdiff_t, not int, for sizes.
4774 (overlays_at, overlays_in): Check for size-calculation overflow.
4775
4776 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
4777
4778 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
4779 (x_session_initialize): Do not assume string length fits in int.
4780
4781 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
4782 This is unlikely, but can occur if DPI is outlandish.
4783
4784 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
4785 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
4786
4787 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
4788 * xrdb.c (magic_file_p, search_magic_path):
4789 Omit last arg SUFFIX; it was always 0. All callers changed.
4790 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
4791
4792 * xfont.c (xfont_match): Avoid need for strlen.
4793
4794 * xfns.c: Don't assume strlen fits in int.
4795 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
4796
4797 * xdisp.c (message_log_check_duplicate): Return intmax_t,
4798 not unsigned long, as we prefer signed integers. All callers changed.
4799 Detect integer overflow in repeat count.
4800 (message_dolog): Don't assume print length fits in 39 bytes.
4801 (display_mode_element): Don't assume strlen fits in int.
4802
4803 * termcap.c: Don't assume sizes fit in int and never overflow.
4804 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
4805 (gobble_line): Check for size-calculation overflow.
4806
4807 * minibuf.c (Fread_buffer):
4808 * lread.c (intern, intern_c_string):
4809 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
4810 Don't assume string length fits in int.
4811
4812 * keyboard.c (parse_tool_bar_item):
4813 * gtkutil.c (style_changed_cb): Avoid need for strlen.
4814

4819 Don't assume integer property fits in fixnum.
4820 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
4821
4822 * filelock.c: Fix some buffer overrun and integer overflow issues.
4823 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
4824 Reformulate so as not to need the command string.
4825 Invoke gzip -cd rather than gunzip, as it's more portable.
4826 (lock_info_type, lock_file_1, lock_file):
4827 Don't assume pid_t and time_t fit in unsigned long.
4828 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
4829 (current_lock_owner): Prefer signed type for sizes.
4830 Use memcpy, not strncpy, where memcpy is what is really wanted.
4831 Don't assume (via atoi) that time_t and pid_t fit in int.
4832 Check for time_t and/or pid_t out of range, e.g., via a network share.
4833 Don't alloca where an auto var works fine.
4834
4835 * fileio.c: Fix some integer overflow issues.
4836 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
4837 Don't assume string length fits in int.
4838 (directory_file_name): Don't assume string length fits in long.
4839 (make_temp_name): Don't assume pid fits in int, or that its print
4840 length is less than 20.
4841
4842 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
4843
4844 * coding.c (make_subsidiaries): Don't assume string length fits in int.
4845
4846 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
4847
4848 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
4849 We prefer signed integers, even for size calculations.
4850
4851 * emacs.c: Don't assume string length fits in 'int'.
4852 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
4853 (main): Don't invoke strlen when not needed.
4854
4855 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
4856 (XD_DEBUG_MESSAGE): Don't waste a byte.
4857
4858 * callproc.c (getenv_internal_1, getenv_internal)
4859 (Fgetenv_internal):
4860 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
4861
4862 * lread.c (invalid_syntax): Omit length argument.
4863 All uses changed. This doesn't fix a bug, but it simplifies the
4864 code away from its former Hollerith-constant appearance, and it's
4865 one less 'int' to worry about when looking at integer-overflow issues.
4866 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
4867
4868 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
4869 This didn't break anything, but it didn't help either.
4870 It's confusing to put a bogus integer in a place where the actual
4871 value does not matter.
4872 (LIST_END_P): Remove unused macro and its bogus comment.
4873 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
4874
4875 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
4876 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
4877 implementation.
4878 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
4879 We prefer signed types, and the value cannot exceed the EMACS_INT
4880 range anyway (because otherwise the length would not be representable).
4881 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
4882 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
4883 This avoids a GCC warning when WIDE_EMACS_INT.
4884
4885 * indent.c (sane_tab_width): New function.
4886 (current_column, scan_for_column, Findent_to, position_indentation)
4887 (compute_motion): Use it. This is just for clarity.
4888 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
4889
4890 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
4891
4892 * lisp.h (lint_assume): New macro.
4893 * composite.c (composition_gstring_put_cache):
4894 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
4895
4896 * editfns.c, insdel.c:
4897 Omit unnecessary forward decls, to simplify future changes.
4898
4899 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
4900
4901 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
4902
4903 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
4904 Use much-faster test for byte-length change.
4905 Don't assume string byte-length fits in 'int'.
4906 Check that character arg fits in 'int'.
4907 (mapcar1): Declare byte as byte, for clarity.
4908
4909 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
4910
4911 * fns.c (concat): Catch string overflow earlier.
4912 Do not rely on integer wraparound.
4913
4914 * dispextern.h (struct it.overlay_strings_charpos)
4915 (struct it.selective): Now EMACS_INT, not int.
4916 * xdisp.c (forward_to_next_line_start)
4917 (back_to_previous_visible_line_start)
4918 (reseat_at_next_visible_line_start, next_element_from_buffer):
4919 Don't arbitrarily truncate the value of 'selective' to int.
4920
4921 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
4922
4923 * composite.c: Don't truncate sizes to 'int'.
4924 (composition_gstring_p, composition_reseat_it)
4925 (composition_adjust_point): Use EMACS_INT, not int.
4926 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
4927 not EMACS_UINT, for indexes.
4928
4929 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
4930
4931 * buffer.c: Include <verify.h>.
4932 (struct sortvec.priority, struct sortstr.priority):
4933 Now EMACS_INT, not int.
4934 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
4935 (struct sortstr.size, record_overlay_string)
4936 (struct sortstrlist.size, struct sortlist.used):
4937 Don't truncate size to int.
4938 (record_overlay_string): Check for size-calculation overflow.
4939 (init_buffer_once): Check at compile-time, not run-time.
4940
4941 2011-06-22 Jim Meyering <meyering@redhat.com>
4942
4943 Don't leak an XBM-image-sized buffer
4944 * image.c (xbm_load): Free the image buffer after using it.
4945
4946 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
4947
4948 Port to Sun C.
4949 * composite.c (find_automatic_composition): Omit needless 'return 0;'
4950 that Sun C diagnosed.
4951 * fns.c (secure_hash): Fix pointer signedness issue.
4952 * intervals.c (static_offset_intervals): New function.
4953 (offset_intervals): Use it.
4954
4955 2011-06-21 Leo Liu <sdl.web@gmail.com>
4956
4957 * deps.mk (fns.o):
4958 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
4959 sha512.h.
4960
4961 * fns.c (secure_hash): Rename from crypto_hash_function and change
4962 the first arg to accept symbols.
4963 (Fsecure_hash): New primitive.
4964 (syms_of_fns): New symbols.
4965
4966 2011-06-20 Deniz Dogan <deniz@dogan.se>
4967
4968 * process.c (Fset_process_buffer): Clarify return value in
4969 docstring.
4970
4971 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
4972
4973 * dispnew.c (add_window_display_history): Use BVAR.
4974
4975 * xdisp.c (debug_method_add): Use BVAR.
4976 (check_window_end, dump_glyph_matrix, dump_glyph)
4977 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
4978
4979 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
4980 Likewise.
4981
4982 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
4983 check till after the cache is created in init_frame_faces.
4984
4985 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
4986
4987 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
4988
4989 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
4990
4991 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
4992 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
4993 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
4994
4995 Improve buffer-overflow checking (Bug#8873).
4996 * fileio.c (Finsert_file_contents):
4997 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
4998 Remove the old (too-loose) buffer overflow checks.
4999 They weren't needed, since make_gap checks for buffer overflow.
5000 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
5001 The old code merely checked for Emacs fixnum overflow, and relied
5002 on undefined (wraparound) behavior. The new code avoids undefined
5003 behavior, and also checks for ptrdiff_t and/or size_t overflow.
5004
5005 * editfns.c (Finsert_char): Don't dump core with very negative counts.
5006 Tune. Don't use wider integers than needed. Don't use alloca.
5007 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
5008
5009 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
5010
5011 * insdel.c, lisp.h (buffer_overflow): New function.
5012 (insert_from_buffer_1, replace_range, replace_range_2):
5013 * insdel.c (make_gap_larger):
5014 * editfns.c (Finsert_char):
5015 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
5016
5017 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
5018
5019 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
5020
5021 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
5022
5023 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
5024 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
5025
5026 * fileio.c: Don't assume EMACS_INT fits in off_t.
5027 (emacs_lseek): New static function.
5028 (Finsert_file_contents, Fwrite_region): Use it.
5029 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
5030
5031 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
5032
5033 * fns.c: Don't overflow int when computing a list length.
5034 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
5035 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
5036 truncation on 64-bit hosts. Check for QUIT every
5037 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
5038 faster and is responsive enough.
5039 (Flength): Report an error instead of overflowing an integer.
5040 (Fsafe_length): Return a float if the value is not representable
5041 as a fixnum. This shouldn't happen except in contrived situations.
5042 (Fnthcdr, Fsort): Don't assume list length fits in int.
5043 (Fcopy_sequence): Don't assume vector length fits in int.
5044
5045 * alloc.c: Check that resized vectors' lengths fit in fixnums.
5046 (header_size, word_size): New constants.
5047 (allocate_vectorlike): Don't check size overflow here.
5048 (allocate_vector): Check it here instead, since this is the only
5049 caller of allocate_vectorlike that could cause overflow.
5050 Check that the new vector's length is representable as a fixnum.
5051
5052 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
5053 The previous code was bogus. For example, next_almost_prime (32)
5054 returned 39, which is undesirable as it is a multiple of 3; and
5055 next_almost_prime (24) returned 25, which is a multiple of 5 so
5056 why was the code bothering to check for multiples of 7?
5057
5058 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
5059
5060 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
5061
5062 Variadic C functions now count arguments with ptrdiff_t.
5063 This partly undoes my 2011-03-30 change, which replaced int with size_t.
5064 Back then I didn't know that the Emacs coding style prefers signed int.
5065 Also, in the meantime I found a few more instances where arguments
5066 were being counted with int, which may truncate counts on 64-bit
5067 machines, or EMACS_INT, which may be unnecessarily wide.
5068 * lisp.h (struct Lisp_Subr.function.aMANY)
5069 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
5070 Arg counts are now ptrdiff_t, not size_t.
5071 All variadic functions and their callers changed accordingly.
5072 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
5073 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
5074 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
5075 * callint.c (Fcall_interactively): Check arg count for overflow,
5076 to avoid potential buffer overrun. Use signed char, not 'int',
5077 for 'varies' array, so that we needn't bother to check its size
5078 calculation for overflow.
5079 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
5080 * eval.c (apply_lambda):
5081 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
5082 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
5083 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
5084
5085 * callint.c (Fcall_interactively): Don't use index var as event count.
5086
5087 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
5088 * mem-limits.h (SIZE): Remove; no longer used.
5089
5090 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
5091
5092 Remove unnecessary casts.
5093 * xterm.c (x_term_init):
5094 * xfns.c (x_set_border_pixel):
5095 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
5096 These aren't needed now that we assume ANSI C.
5097
5098 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
5099 It's more likely to cause problems (due to unsigned overflow)
5100 than to cure them.
5101
5102 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
5103
5104 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
5105
5106 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
5107
5108 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
5109
5110 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
5111
5112 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
5113
5114 GLYPH_CODE_FACE returns EMACS_INT, not int.
5115 * dispextern.h (merge_faces):
5116 * xfaces.c (merge_faces):
5117 * xdisp.c (get_next_display_element, next_element_from_display_vector):
5118 Don't assume EMACS_INT fits in int.
5119
5120 * character.h (CHAR_VALID_P): Remove unused parameter.
5121 * fontset.c, lisp.h, xdisp.c: All uses changed.
5122
5123 * editfns.c (Ftranslate_region_internal): Omit redundant test.
5124
5125 * fns.c (concat): Minor tuning based on overflow analysis.
5126 This doesn't fix any bugs. Use int to hold character, instead
5127 of constantly refetching from Emacs object. Use XFASTINT, not
5128 XINT, for value known to be a character. Don't bother comparing
5129 a single byte to 0400, as it's always less.
5130
5131 * floatfns.c (Fexpt):
5132 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
5133
5134 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
5135 for characters.
5136
5137 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
5138
5139 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
5140 Without this fix, on a 64-bit host (aset S 0 4294967386) would
5141 incorrectly succeed when S was a string, because 4294967386 was
5142 truncated before it was used.
5143
5144 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
5145 Otherwise, an out-of-range integer could cause undefined behavior
5146 on a 64-bit host.
5147
5148 * composite.c: Use int, not EMACS_INT, for characters.
5149 (fill_gstring_body, composition_compute_stop_pos): Use int, not
5150 EMACS_INT, for values that are known to be in character range.
5151 This doesn't fix any bugs but is the usual style inside Emacs and
5152 may generate better code on 32-bit machines.
5153
5154 Make sure a 64-bit char is never passed to ENCODE_CHAR.
5155 This is for reasons similar to the recent CHAR_STRING fix.
5156 * charset.c (Fencode_char): Check that character arg is actually
5157 a character. Pass an int to ENCODE_CHAR.
5158 * charset.h (ENCODE_CHAR): Verify that the character argument is no
5159 wider than 'int', as a compile-time check to prevent future regressions
5160 in this area.
5161
5162 * character.c (char_string): Remove unnecessary casts.
5163
5164 Make sure a 64-bit char is never passed to CHAR_STRING.
5165 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
5166 by silently ignoring the top 32 bits, allowing some values
5167 that were far too large to be valid characters.
5168 * character.h: Include <verify.h>.
5169 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
5170 arguments are no wider than unsigned, as a compile-time check
5171 to prevent future regressions in this area.
5172 * data.c (Faset):
5173 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
5174 (Fsubst_char_in_region):
5175 * fns.c (concat):
5176 * xdisp.c (decode_mode_spec_coding):
5177 Adjust to CHAR_STRING's new requirement.
5178 * editfns.c (Finsert_char, Fsubst_char_in_region):
5179 * fns.c (concat): Check that character args are actually
5180 characters. Without this test, these functions did the wrong
5181 thing with wildly out-of-range values on 64-bit hosts.
5182
5183 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
5184 These casts should not be needed on 32-bit hosts, either.
5185 * keyboard.c (read_char):
5186 * lread.c (Fload): Remove casts to unsigned.
5187
5188 * lisp.h (UNSIGNED_CMP): New macro.
5189 This fixes comparison bugs on 64-bit hosts.
5190 (ASCII_CHAR_P): Use it.
5191 * casefiddle.c (casify_object):
5192 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
5193 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
5194 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
5195 * dispextern.h (FACE_FROM_ID):
5196 * keyboard.c (read_char): Use UNSIGNED_CMP.
5197
5198 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
5199 not to EMACS_INT, to avoid GCC warning.
5200
5201 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
5202
5203 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
5204 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
5205 isn't needed on 32-bit machines.
5206
5207 * buffer.c (Fgenerate_new_buffer_name):
5208 Use EMACS_INT for count, not int.
5209 (advance_to_char_boundary): Return EMACS_INT, not int.
5210
5211 * data.c (Qcompiled_function): Now static.
5212
5213 * window.c (window_body_lines): Now static.
5214
5215 * image.c (gif_load): Rename local to avoid shadowing.
5216
5217 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
5218 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
5219 * alloc.c (make_save_value): Integer argument is now of type
5220 ptrdiff_t, not int.
5221 (mark_object): Use ptrdiff_t, not int.
5222 * lisp.h (pD): New macro.
5223 * print.c (print_object): Use it.
5224
5225 * alloc.c: Use EMACS_INT, not int, to count objects.
5226 (total_conses, total_markers, total_symbols, total_vector_size)
5227 (total_free_conses, total_free_markers, total_free_symbols)
5228 (total_free_floats, total_floats, total_free_intervals)
5229 (total_intervals, total_strings, total_free_strings):
5230 Now EMACS_INT, not int. All uses changed.
5231 (Fgarbage_collect): Compute overall total using a double, so that
5232 integer overflow is less likely to be a problem. Check for overflow
5233 when converting back to an integer.
5234 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
5235 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
5236 These were 'int' variables that could overflow on 64-bit hosts;
5237 they were never used, so remove them instead of repairing them.
5238 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
5239 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
5240 Previously, this ceilinged at INT_MAX, but that doesn't work on
5241 64-bit machines.
5242 (allocate_pseudovector): Don't use EMACS_INT when int would do.
5243
5244 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
5245 (allocate_vectorlike): Check for ptrdiff_t overflow.
5246 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
5247 when a (possibly-narrower) signed value would do just as well.
5248 We prefer using signed arithmetic, to avoid comparison confusion.
5249
5250 * alloc.c: Catch some string size overflows that we were missing.
5251 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
5252 for convenience in STRING_BYTES_MAX.
5253 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
5254 The definition here is exact; the one in lisp.h was approximate.
5255 (allocate_string_data): Check for string overflow. This catches
5256 some instances we weren't catching before. Also, it catches
5257 size_t overflow on (unusual) hosts where SIZE_MAX <= min
5258 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
5259 and ptrdiff_t and EMACS_INT are both 64 bits.
5260
5261 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
5262 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
5263 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
5264
5265 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
5266
5267 * alloc.c (Fmake_string): Check for out-of-range init.
5268
5269 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
5270
5271 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
5272

5276 xg_get_default_scrollbar_width.
5277

5288 (update_theme_scrollbar_width): New function.
5289 (xg_get_default_scrollbar_width): Move code to
5290 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
5291 (xg_initialize): Call update_theme_scrollbar_width.
5292
5293 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
5294
5295 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
5296
5297 2011-06-12 Martin Rudalics <rudalics@gmx.at>
5298

5300 other_buffer.
5301
5302 * window.c (temp_output_buffer_show): Call display_buffer with
5303 second argument Vtemp_buffer_show_specifiers and reset latter
5304 immediately after the call.

5307 (Vscroll_preserve_screen_position): Remove leading asterisks from
5308 doc-strings.
5309

5324 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
5325 Define only if HAVE_GPM.
5326 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
5327 (update_hints_inhibit): Remove; never set. All uses removed.
5328 * widgetprv.h (emacsFrameClassRec): Remove decl.
5329 * window.c (delete_deletable_window): Now returns void, since it
5330 wasn't returning anything.
5331 (compare_window_configurations): Remove unused locals.
5332 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
5333 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.

5377 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
5378 calls to replace_buffer_in_windows and
5379 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
5380 if allowed.

5896
5897 Malloc failure behavior now depends on size of allocation.
5898 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
5899 * lisp.h: Change signatures accordingly.
5900 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
5901 All callers changed. (Bug#8762)
5902
5903 * gnutls.c: Use Emacs's memory allocators.
5904 Without this change, the gnutls library would invoke malloc etc.
5905 directly, which causes problems on non-SYNC_INPUT hosts, and which
5906 runs afoul of improving memory_full behavior. (Bug#8761)
5907 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
5908 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
5909 xfree instead of the default malloc, realloc, free.
5910 (Fgnutls_boot): No need to check for memory allocation failure,
5911 since xmalloc does that for us.
5912
5913 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
5914 * category.c (hash_get_category_set):
5915 * ccl.c (ccl_driver):
5916 * charset.c (Fdefine_charset_internal):
5917 * charset.h (struct charset.hash_index):
5918 * composite.c (get_composition_id, gstring_lookup_cache)
5919 (composition_gstring_put_cache):
5920 * composite.h (struct composition.hash_index):
5921 * dispextern.h (struct image.hash):
5922 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
5923 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
5924 (hashfn_equal, hashfn_user_defined, make_hash_table)
5925 (maybe_resize_hash_table, hash_lookup, hash_put)
5926 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
5927 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
5928 (Fsxhash, Fgethash, Fputhash, Fmaphash):
5929 * image.c (make_image, search_image_cache, lookup_image)
5930 (xpm_put_color_table_h):
5931 * lisp.h (struct Lisp_Hash_Table):
5932 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
5933 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
5934 for hashes and hash indexes, instead of 'unsigned' and 'int'.
5935 * alloc.c (allocate_vectorlike):
5936 Check for overflow in vector size calculations.
5937 * ccl.c (ccl_driver):
5938 Check for overflow when converting EMACS_INT to int.
5939 * fns.c, image.c: Remove unnecessary static decls that would otherwise
5940 need to be updated by these changes.
5941 * fns.c (make_hash_table, maybe_resize_hash_table):
5942 Check for integer overflow with large hash tables.
5943 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
5944 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
5945 (SXHASH_REDUCE): New macro.
5946 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
5947 Use it instead of discarding useful hash info with large hash values.
5948 (sxhash_float): New function.
5949 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
5950 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
5951 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
5952 Rewrite to use FIXNUM_BITS, as this simplifies things.
5953 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
5954 Adjust signatures to match updated version of code.
5955 (consing_since_gc): Now EMACS_INT, since a single hash table can
5956 use more than INT_MAX bytes.
5957
5958 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
5959
5960 Make it possible to build with GCC-4.6+ -O2 -flto.

5963
5964 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
5965
5966 * minibuf.c (get_minibuffer, read_minibuf_unwind):
5967 Call minibuffer-inactive-mode.
5968
5969 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
5970
5971 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
5972 Update dependencies.
5973
5974 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
5975
5976 * data.c (init_data): Remove code for UTS, this system is not
5977 supported anymore.
5978
5979 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
5980
5981 Don't force ./temacs to start in terminal mode.
5982
5983 * frame.c (make_initial_frame): Initialize faces in all cases, not
5984 only when CANNOT_DUMP is defined.
5985 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
5986
5987 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
5988
5989 * dispnew.c (add_window_display_history): Use const for the string
5990 pointer. Remove declaration, not needed.
5991
5992 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
5993
5994 Use 'inline', not 'INLINE'.
5995 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
5996 * alloc.c, fontset.c (INLINE): Remove.
5997 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
5998 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
5999 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
6000 * gmalloc.c (register_heapinfo): Use inline unconditionally.
6001 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
6002
6003 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6004
6005 Make it possible to run ./temacs.
6006
6007 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
6008 syms_of_callproc does the same thing. Remove test for
6009 "initialized", do it in the caller.
6010 * emacs.c (main): Avoid calling set_initial_environment when dumping.
6011
6012 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
6013
6014 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
6015 (read_minibuf): Use get_minibuffer.
6016 (syms_of_minibuf): Use DEFSYM.
6017 (Qmetadata): New var.
6018 * data.c (Qbuffer): Don't make it static.
6019 (syms_of_data): Use DEFSYM.
6020
6021 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
6022
6023 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
6024 (CCL_CODE_MIN): New macro.
6025
6026 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
6027
6028 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
6029
6030 * eval.c (Qdebug): Now static.
6031 * lisp.h (Qdebug): Remove decl. This reverts a part of the
6032 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
6033 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
6034
6035 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
6036
6037 * image.c: Various fixes to ImageMagick code comments.
6038 (Fimagemagick_types): Doc fix.
6039
6040 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
6041
6042 Minor fixes prompted by GCC 4.6.0 warnings.
6043
6044 * xselect.c (converted_selections, conversion_fail_tag): Now static.
6045
6046 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
6047 (x_clipboard_manager_save_all): Move extern decl to ...
6048 * xterm.h: ... here, so that it can be checked for consistency.
6049
6050 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
6051
6052 * xselect.c (x_clipboard_manager_save_frame)
6053 (x_clipboard_manager_save_all): New functions.
6054 (Fx_clipboard_manager_save): Lisp function deleted.
6055
6056 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
6057 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
6058
6059 * xterm.h: Update prototype.
6060
6061 2011-05-28 William Xu <william.xwl@gmail.com>
6062
6063 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
6064 exiting (Bug#8239).
6065
6066 2011-05-28 Jim Meyering <meyering@redhat.com>
6067
6068 Avoid a sign-extension bug in crypto_hash_function.
6069 * fns.c (to_uchar): Define.
6070 (crypto_hash_function): Use it to convert some newly-signed
6071 variables to unsigned, to avoid sign-extension bugs. For example,
6072 without this change, (md5 "truc") would evaluate to
6073 45723a2aff78ff4fff7fff1114760e62 rather than the expected
6074 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
6075 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
6076
6077 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
6078
6079 Integer overflow fixes.
6080
6081 * dbusbind.c: Serial number integer overflow fixes.
6082 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
6083 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
6084 to hold a serial number that is too large for a fixnum.
6085 (Fdbus_method_return_internal, Fdbus_method_error_internal):
6086 Check for serial numbers out of range. Decode any serial number
6087 that was so large that it became a float. (Bug#8722)
6088
6089 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
6090 (Fdbus_call_method, Fdbus_call_method_asynchronously):
6091 Use XFASTINT rather than XUINT when numbers are nonnegative.
6092 (xd_append_arg, Fdbus_method_return_internal):
6093 (Fdbus_method_error_internal): Likewise. Also, for unsigned
6094 arguments, check that Lisp number is nonnegative, rather than
6095 silently wrapping negative numbers around. (Bug#8722)
6096 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
6097 (Bug#8722)
6098
6099 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
6100
6101 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
6102
6103 ccl: Add integer overflow checks.
6104 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
6105 (IN_INT_RANGE): New macros.
6106 (ccl_driver): Use them to check for integer overflow when
6107 decoding a CCL program. Many of the new checks are whether XINT (x)
6108 fits in int; it doesn't always, on 64-bit hosts. The new version
6109 doesn't catch all possible integer overflows, but it's an
6110 improvement. (Bug#8719)
6111
6112 * alloc.c (make_event_array): Use XINT, not XUINT.
6113 There's no need for unsigned here.
6114
6115 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
6116 This follows up to the 2011-05-06 change that substituted uintptr_t
6117 for EMACS_INT. This case wasn't caught back then.
6118
6119 Rework Fformat to avoid integer overflow issues.
6120 * editfns.c: Include <float.h> unconditionally, as it's everywhere
6121 now (part of C89). Include <verify.h>.
6122 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
6123 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
6124 (Fformat): Avoid the prepass trying to compute sizes; it was only
6125 approximate and thus did not catch overflow reliably. Instead, walk
6126 through the format just once, formatting and computing sizes as we go,
6127 checking for integer overflow at every step, and allocating a larger
6128 buffer as needed. Keep track separately whether the format is
6129 multibyte. Keep only the most-recently calculated precision, rather
6130 than them all. Record whether each argument has been converted to
6131 string. Use EMACS_INT, not int, for byte and char and arg counts.
6132 Support field widths and precisions larger than INT_MAX. Avoid
6133 sprintf's undefined behavior with conversion specifications such as %#d
6134 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
6135 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
6136 formatting out-of-range floating point numbers with int
6137 formats. (Bug#8668)
6138
6139 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
6140
6141 * data.c: Avoid integer truncation in expressions involving floats.
6142 * data.c: Include <intprops.h>.
6143 (arith_driver): When there's an integer overflow in an expression
6144 involving floating point, convert the integers to floating point
6145 so that the resulting value does not suffer from catastrophic
6146 integer truncation. For example, on a 64-bit host (* 4
6147 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
6148 Do not rely on undefined behavior after integer overflow.
6149
6150 merge count_size_as_multibyte, parse_str_to_multibyte
6151 * character.c, character.h (count_size_as_multibyte):
6152 Rename from parse_str_to_multibyte; all uses changed.
6153 Check for integer overflow.
6154 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
6155 since it's now a duplicate of the other. This is more of
6156 a character than a buffer op, so better that it's in character.c.
6157 * fns.c, print.c: Adjust to above changes.
6158
6159 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
6160
6161 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
6162
6163 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
6164
6165 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
6166 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
6167 (x_clipboard_manager_save): Now static.
6168 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
6169
6170 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
6171 (crypto_hash_function): Now static.
6172 Fix pointer signedness problems. Avoid unnecessary initializations.
6173
6174 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
6175
6176 * termhooks.h (Vselection_alist): Make it terminal-local.
6177
6178 * terminal.c (create_terminal): Initialize it.
6179
6180 * xselect.c: Support for clipboard managers.
6181 (Vselection_alist): Move to termhooks.h as terminal-local var.
6182 (LOCAL_SELECTION): New macro.
6183 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
6184 (symbol_to_x_atom): Remove gratuitous arg.
6185 (x_handle_selection_request, lisp_data_to_selection_data)
6186 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
6187 (x_own_selection, x_get_local_selection, x_convert_selection):
6188 New arg, specifying work frame. Use terminal-local Vselection_alist.
6189 (some_frame_on_display): Delete unused function.
6190 (Fx_own_selection_internal, Fx_get_selection_internal)
6191 (Fx_disown_selection_internal, Fx_selection_owner_p)
6192 (Fx_selection_exists_p): New optional frame arg.
6193 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
6194 (x_handle_selection_clear): Don't treat other terminals with the
6195 same keyboard specially. Use the terminal-local Vselection_alist.
6196 (x_clear_frame_selections): Use Frun_hook_with_args.
6197
6198 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
6199
6200 * xterm.h: Add support for those atoms.
6201
6202 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
6203
6204 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
6205 (converted_selections, conversion_fail_tag): New global variables.
6206 (x_selection_request_lisp_error): Free the above.
6207 (x_get_local_selection): Remove unnecessary code.
6208 (x_reply_selection_request): Args changed; handle arbitrary array
6209 of converted selections stored in converted_selections.
6210 Separate the XChangeProperty and SelectionNotify steps.
6211 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
6212 (x_convert_selection): New function.
6213 (x_handle_selection_event): Simplify.
6214 (x_get_foreign_selection): Don't ignore incoming requests while
6215 waiting for an answer; this will fail when we implement
6216 SAVE_TARGETS, and seems unnecessary anyway.
6217 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
6218 (Vx_sent_selection_functions): Doc fix.
6219
6220 2011-05-26 Leo Liu <sdl.web@gmail.com>

6229 for fringe update if it has periodic bitmap.
6230 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
6231 and fringe_bitmap_periodic_p.

6234 (draw_fringe_bitmap_1, update_window_fringes): Use it.
6235 (update_window_fringes): Record periodicity of fringe bitmap in glyph
6236 row. Mark glyph row for fringe update if periodicity changed.

6258 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
6259 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
6260 Remove macros that are defined and never used.
6261 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
6262
6263 2011-05-22 Chong Yidong <cyd@stupidchicken.com>

6280 * dispnew.c (scrolling_window): Don't exclude the case that the
6281 last enabled row in the desired matrix touches the bottom boundary.
6282
6283 2011-05-21 Glenn Morris <rgm@gnu.org>
6284
6285 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
6286 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
6287 and add some more files.
6288
6289 2011-05-20 Eli Zaretskii <eliz@gnu.org>
6290
6291 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
6292 report_file_error introduced by the change from 2011-05-07.
6293
6294 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
6295
6296 * systime.h (Time): Define only if emacs is defined.
6297 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
6298 where the include path doesn't have X11/X.h by default. See
6299 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

6301 2011-05-20 Kenichi Handa <handa@m17n.org>
6302
6303 * composite.c (find_automatic_composition): Fix previous change.
6304
6305 2011-05-20 Glenn Morris <rgm@gnu.org>
6306
6307 * lisp.mk: New file, split from Makefile.in.
6308 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
6309 (shortlisp): Remove.
6310 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
6311
6312 2011-05-19 Glenn Morris <rgm@gnu.org>
6313
6314 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
6315 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
6316 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
6317 (lisp): Set the order to that of loadup.el.
6318 (shortlisp): Make it a copy of $lisp.
6319 (SOME_MACHINE_LISP): Remove.
6320 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
6321 Use just $shortlisp, not $SOME_MACHINE_LISP too.
6322
6323 2011-05-18 Kenichi Handa <handa@m17n.org>
6324
6325 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
6326 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
6327 (find_automatic_composition): Mostly rewrite for efficiency.
6328
6329 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
6330
6331 * makefile.w32-in: Update dependencies.
6332
6333 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
6334
6335 * menu.c: Include limits.h (fixes the MS-Windows build broken by
6336 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
6337
6338 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
6339
6340 Fix some integer overflow issues, such as string length overflow.
6341
6342 * insdel.c (count_size_as_multibyte): Check for string overflow.
6343
6344 * character.c (lisp_string_width): Check for string overflow.
6345 Use EMACS_INT, not int, for string indexes and lengths; in
6346 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
6347 the resulting string length overflows an EMACS_INT; instead,
6348 report a string overflow if no precision given. When checking for
6349 precision exhaustion, use a check that cannot possibly have
6350 integer overflow. (Bug#8675)
6351 * character.h (lisp_string_width): Adjust to new signature.
6352
6353 * alloc.c (string_overflow): New function.
6354 (Fmake_string): Use it. This doesn't change behavior, but saves
6355 a few bytes and will simplify future changes.
6356 * character.c (string_escape_byte8): Likewise.
6357 * lisp.h (string_overflow): New decl.
6358
6359 Fixups, following up to the user-interface timestamp change.
6360 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
6361 for UI timestamps, instead of unsigned long.
6362 * msdos.c (mouse_get_pos): Likewise.
6363 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
6364 * w32gui.h (Time): Define by including "systime.h" rather than by
6365 declaring it ourselves. (Bug#8664)
6366
6367 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
6368 * image.c (clear_image_cache): Likewise.
6369
6370 * term.c (term_mouse_position): Don't assume time_t wraparound.
6371
6372 Be more systematic about user-interface timestamps.
6373 Before, the code sometimes used 'Time', sometimes 'unsigned long',
6374 and sometimes 'EMACS_UINT', to represent these timestamps.
6375 This change causes it to use 'Time' uniformly, as that's what X uses.
6376 This makes the code easier to follow, and makes it easier to catch
6377 integer overflow bugs such as Bug#8664.
6378 * frame.c (Fmouse_position, Fmouse_pixel_position):
6379 Use Time, not unsigned long, for user-interface timestamps.
6380 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
6381 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
6382 * keyboard.h (last_event_timestamp): Likewise.
6383 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
6384 * menu.h (xmenu_show): Likewise.
6385 * term.c (term_mouse_position): Likewise.
6386 * termhooks.h (struct input_event.timestamp): Likewise.
6387 (struct terminal.mouse_position_hook): Likewise.
6388 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
6389 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
6390 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
6391 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
6392 what it was before.
6393 * menu.h, termhooks.h: Include "systime.h", for Time.
6394
6395 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
6396 Don't assume that the difference between two unsigned long values
6397 can fit into an integer. At this point, we know button_down_time
6398 <= event->timestamp, so the difference must be nonnegative, so
6399 there's no need to cast the result if double-click-time is
6400 nonnegative, as it should be; check that it's nonnegative, just in
6401 case. This bug is triggered when events are more than 2**31 ms
6402 apart (about 25 days). (Bug#8664)
6403
6404 * xselect.c (last_event_timestamp): Remove duplicate decl.
6405 (x_own_selection): Remove needless cast to unsigned long.
6406
6407 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
6408 that always fit in int. Use a sentinel instead of a counter, to
6409 avoid a temp and to allay GCC's concerns about possible int overflow.
6410 * frame.h (struct frame): Use int for menu_bar_items_used
6411 instead of EMACS_INT, since it always fits in int.
6412
6413 * menu.c (grow_menu_items): Check for int overflow.
6414
6415 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
6416
6417 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
6418 Before, the code was not consistent. These values cannot exceed
6419 2**31 - 1 so there's no need to make them unsigned.
6420 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
6421 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
6422 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
6423 as modifiers.
6424 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
6425
6426 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
6427 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
6428 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
6429 presumably because the widths might not match.
6430
6431 * window.c (size_window): Avoid needless test at loop start.
6432
6433 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
6434
6435 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
6436
6437 2011-05-12 Drew Adams <drew.adams@oracle.com>
6438
6439 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
6440
6441 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6442
6443 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
6444 `width' to `bar_area_x' and `bar_area_width', respectively.
6445 (x_scroll_run): Take account of fringe background extension.
6446
6447 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
6448 Rename local vars `left' and `width' to `bar_area_x' and
6449 `bar_area_width', respectively.
6450 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
6451 background extension.
6452
6453 2011-05-10 Jim Meyering <meyering@redhat.com>
6454
6455 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
6456
6457 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
6458
6459 * image.c (Finit_image_library): Return t for built-in image types,
6460 like pbm and xbm. (Bug#8640)
6461
6462 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
6463
6464 * w32menu.c (set_frame_menubar): Fix submenu allocation.
6465
6466 2011-05-07 Eli Zaretskii <eliz@gnu.org>
6467
6468 * w32console.c (Fset_screen_color): Doc fix.
6469 (Fget_screen_color): New function.
6470 (syms_of_ntterm): Defsubr it.
6471
6472 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
6473 unlink the temporary file if Fcall_process didn't create it in the
6474 first place.
6475 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
6476 child process will be redirected to a file specified with `:file'.
6477 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
6478 cue to call_process_cleanup not to close that handle.
6479
6480 2011-05-07 Ben Key <bkey76@gmail.com>
6481
6482 * makefile.w32-in: The bootstrap-temacs rule now makes use of
6483 one of two shell specific rules, either bootstrap-temacs-CMD or
6484 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
6485 to the previous implementation of the bootstrap-temacs rule.
6486 The bootstrap-temacs-CMD rule is similar to the previous
6487 implementation of the bootstrap-temacs rule except that it
6488 makes use of the ESC_CFLAGS variable instead of the CFLAGS
6489 variable.
6490
6491 These changes, along with some changes to nt/configure.bat,
6492 nt/gmake.defs, and nt/nmake.defs, are required to extend my
6493 earlier fix to add support for --cflags and --ldflags options
6494 that include quotes so that it works whether make uses cmd or
6495 sh as the shell.
6496
6497 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
6498
6499 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
6500 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
6501 is a constant.
6502 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
6503 a string. Handle both cases.
6504 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
6505 (Fdbus_register_method): Use Qinvalid_function.
6506
6507 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6508
6509 * makefile.w32-in: Update dependencies.
6510 (LISP_H): Add inttypes.h and stdin.h.
6511 (PROCESS_H): Add unistd.h.
6512
6513 2011-05-06 Eli Zaretskii <eliz@gnu.org>
6514
6515 * lread.c: Include limits.h (fixes the MS-Windows build broken by
6516 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
6517
6518 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
6519
6520 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
6521
6522 * term.c (vfatal): Remove stray call to va_end.
6523 It's not needed and the C Standard doesn't allow it here anyway.
6524
6525 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
6526 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
6527
6528 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
6529 bytes.
6530
6531 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
6532
6533 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
6534
6535 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
6536
6537 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
6538
6539 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
6540
6541 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
6542 * charset.c (Fdefine_charset_internal): Don't initialize
6543 charset.code_space[15]. The value was garbage, on hosts with
6544 32-bit int (Bug#8600).
6545
6546 * lread.c (read_integer): Be more consistent with string-to-number.
6547 Use string_to_number to do the actual conversion; this avoids
6548 rounding errors and fixes some other screwups. Without this fix,
6549 for example, #x1fffffffffffffff was misread as -2305843009213693952.
6550 (digit_to_number): Move earlier, for benefit of read_integer.
6551 Return -1 if the digit is out of range for the base, -2 if it is
6552 not a digit in any supported base. (Bug#8602)
6553
6554 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
6555
6556 * dispnew.c (scrolling_window): Return 1 if we scrolled,
6557 to match comment at start of function. This also removes a
6558 GCC warning about overflow in a 32+64-bit port.
6559
6560 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
6561
6562 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
6563 Reported by Stefan Monnier in
6564 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
6565 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6566 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
6567
6568 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
6569 (EMACS_UINTPTR): Likewise, with uintptr_t.
6570
6571 * lisp.h: Prefer 64-bit EMACS_INT if available.
6572 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
6573 on 32-bit hosts that have 64-bit int, so that they can access
6574 large files.
6575 However, temporarily disable this change unless the temporary
6576 symbol WIDE_EMACS_INT is defined.
6577
6578 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
6579
6580 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
6581 This removes an assumption that EMACS_INT and long are the same
6582 width as pointers. The assumption is true for Emacs porting targets
6583 now, but we want to make other targets possible.
6584 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
6585 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
6586 In the rest of the code, change types of integers that hold casted
6587 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
6588 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
6589 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
6590 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
6591 No need to cast type when ORing.
6592 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
6593 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
6594 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
6595 assume EMACS_INT is the same width as char *.
6596 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
6597 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
6598 Remove no-longer-needed casts.
6599 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
6600 (xg_tool_bar_help_callback, xg_make_tool_item):
6601 Use EMACS_INTPTR to hold an integer
6602 that will be cast to void *; this can avoid a GCC warning
6603 if EMACS_INT is not the same width as void *.
6604 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
6605 * xdisp.c (display_echo_area_1, resize_mini_window_1):
6606 (current_message_1, set_message_1):
6607 Use a local to convert to proper width without a cast.
6608 * xmenu.c (dialog_selection_callback): Likewise.
6609
6610 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
6611 Also, don't assume VALBITS / RAND_BITS is less than 5,
6612 and don't rely on undefined behavior when shifting a 1 left into
6613 the sign bit.
6614 * lisp.h (get_random): Change signature to match.
6615
6616 * lread.c (hash_string): Use size_t, not int, for hash computation.
6617 Normally we prefer signed values; but hashing is special, because
6618 it's better to use unsigned division on hash table sizes so that
6619 the remainder is nonnegative. Also, size_t is the natural width
6620 for hashing into memory. The previous code used 'int', which doesn't
6621 retain enough info to hash well into very large tables.
6622 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
6623
6624 * dbusbind.c: Don't possibly lose pointer info when converting.
6625 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6626 Use XPNTR rather than XHASH, so that the high-order bits of
6627 the pointer aren't lost when converting through void *.
6628
6629 * eval.c (Fautoload): Don't double-shift a pointer.
6630
6631 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
6632
6633 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6634
6635 * gnutls.c (DEF_GNUTLS_FN):
6636 * image.c (DEF_IMGLIB_FN): Make function pointers static.
6637
6638 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
6639
6640 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
6641 marker. (Bug#8610)
6642
6643 2011-05-05 Eli Zaretskii <eliz@gnu.org>
6644
6645 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
6646 New version that can reserve upto 2GB of heap space.
6647
6648 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
6649
6650 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
6651
6652 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
6653
6654 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
6655 `gnutls_certificate_set_x509_key_file'.
6656
6657 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
6658
6659 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
6660 Update dependencies.
6661
6662 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6663
6664 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
6665 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
6666 Remove unused parameter `fildes'.
6667 * process.c (read_process_output, send_process): Don't pass it.
6668
6669 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6670
6671 Fix previous change: the library cache is defined in w32.c.
6672 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
6673 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
6674
6675 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6676
6677 Implement dynamic loading of GnuTLS on Windows.
6678
6679 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
6680 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
6681 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
6682 Declare.
6683
6684 * gnutls.c (Qgnutls_dll): Define.
6685 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
6686 (gnutls_*): Declare function pointers.
6687 (init_gnutls_functions): New function to initialize function pointers.
6688 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
6689 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
6690 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
6691 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
6692 (emacs_gnutls_write, emacs_gnutls_read)
6693 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
6694 (Fgnutls_available_p): New function.
6695 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
6696 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
6697 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
6698
6699 * image.c: Include w32.h.

6721
6722 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
6723 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
6724 as passed in.

6756
6757 * sysdep.c (interruptible_wait_for_termination): New function
6758 which is like wait_for_termination, but allows keyboard
6759 interruptions.
6760
6761 * callproc.c (Fcall_process): Add (:file "file") as an option for
6762 the STDOUT buffer.
6763 (Fcall_process_region): Ditto.

6768 rather than `XVECTOR (FOO)->size'.
6769
6770 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
6771 inttypes.h, as a gnulib replacement is used if it not available in
6772 system headers.
6773

6778 of MOST_POSITIVE_FIXNUM. (Bug#8528)
6779
6780 * coding.c (coding_alloc_by_realloc): Error out if destination
6781 will grow beyond MOST_POSITIVE_FIXNUM.
6782 (decode_coding_emacs_mule): Abort if there isn't enough place in
6783 charbuf for the composition carryover bytes. Reserve an extra
6784 space for up to 2 characters produced in a loop.
6785 (decode_coding_iso_2022): Abort if there isn't enough place in

6791 aborting when %lld or %lll format is passed.
6792 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
6793 %llo or %llx format is passed. (Bug#8545)
6794
6795 * window.c (window_scroll_line_based): Use a marker instead of
6796 simple variables to record original value of point. (Bug#7952)
6797
6798 * doprnt.c (doprnt): Fix the case where a multibyte sequence
6799 produced by %s or %c overflows available buffer space. (Bug#8545)
6800
6801 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
6802
6803 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

6809
6810 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
6811
6812 * keyboard.c (Qdelayed_warnings_hook): Define.
6813 (command_loop_1): Run `delayed-warnings-hook'
6814 if Vdelayed_warnings_list is non-nil.
6815 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
6816 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
6817
6818 2011-04-28 Eli Zaretskii <eliz@gnu.org>
6819
6820 * doprnt.c (doprnt): Don't return value smaller than the buffer
6821 size if the message was truncated. (Bug#8545).
6822
6823 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
6824
6825 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
6826 (Fx_window_property): #if-0 the whole functions, not just the bodies.
6827
6828 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6829
6830 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
6831
6832 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
6833

6835
6836 2011-04-27 Eli Zaretskii <eliz@gnu.org>
6837
6838 Improve `doprnt' and its usage. (Bug#8545)
6839 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
6840 `format_end'. Remove support for %l as a conversion specifier.
6841 Don't use xrealloc. Improve diagnostics when the %l size modifier
6842 is used. Update the commentary.
6843
6844 * eval.c (verror): Simplify calculation of size_t.
6845
6846 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
6847 messages.
6848
6849 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
6850
6851 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
6852 change.
6853
6854 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6855
6856 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
6857 This makes this file independent of the recent pseudovector change.
6858
6859 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
6860
6861 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
6862
6863 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
6864 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
6865 Remove unused local.
6866 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
6867
6868 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
6869 GCC 4.6.0 optimizes based on type-based alias analysis.
6870 For example, if b is of type struct buffer * and v of type struct
6871 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
6872 != &v->size, and therefore "v->size = 1; b->size = 2; return
6873 v->size;" must therefore return 1. This assumption is incorrect
6874 for Emacs, since it type-puns struct Lisp_Vector * with many other
6875 types. To fix this problem, this patch adds a new type struct
6876 vectorlike_header that documents the constraints on layout of vectors
6877 and pseudovectors, and helps optimizing compilers not get fooled
6878 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
6879 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
6880 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
6881 the size member.
6882 (XSETPVECTYPE): Rewrite in terms of new macro.
6883 (XSETPVECTYPESIZE): New macro, specifying both type and size.
6884 This is a bit clearer, and further avoids the possibility of
6885 undesirable aliasing.
6886 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
6887 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
6888 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
6889 since Lisp_Subr is a special case (no "next" field).
6890 (ASIZE): Now uses header.size rather than size.
6891 All previous uses of XVECTOR (foo)->size replaced to use this macro,
6892 to avoid the hassle of writing XVECTOR (foo)->header.size.
6893 (struct vectorlike_header): New type.
6894 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
6895 object, to help avoid aliasing.
6896 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
6897 (SUBRP): Likewise, since Lisp_Subr is a special case.
6898 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
6899 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
6900 (struct Lisp_Hash_Table): Combine first two members into a single
6901 struct vectorlike_header member. All uses of "size" and "next" members
6902 changed to be "header.size" and "header.next".
6903 * buffer.h (struct buffer): Likewise.
6904 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
6905 * frame.h (struct frame): Likewise.
6906 * process.h (struct Lisp_Process): Likewise.
6907 * termhooks.h (struct terminal): Likewise.
6908 * window.c (struct save_window_data, struct saved_window): Likewise.
6909 * window.h (struct window): Likewise.
6910 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
6911 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
6912 * buffer.c (init_buffer_once): Likewise.
6913 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
6914 special case.
6915 * process.c (Fformat_network_address): Use local var for size,
6916 for brevity.
6917
6918 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
6919
6920 Make the Lisp reader and string-to-float more consistent (Bug#8525)
6921 * data.c (atof): Remove decl; no longer used or needed.
6922 (digit_to_number): Move to lread.c.
6923 (Fstring_to_number): Use new string_to_number function, to be
6924 consistent with how the Lisp reader treats infinities and NaNs.
6925 Do not assume that floating-point numbers represent EMACS_INT
6926 without losing information; this is not true on most 64-bit hosts.
6927 Avoid double-rounding errors, by insisting on integers when
6928 parsing non-base-10 numbers, as the documentation specifies.
6929 * lisp.h (string_to_number): New decl, replacing ...
6930 (isfloat_string): Remove.
6931 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
6932 (read1): Do not accept +. and -. as integers; this
6933 appears to have been a coding error. Similarly, do not accept
6934 strings like +-1e0 as floating point numbers. Do not report
6935 overflow for integer overflows unless the base is not 10 which
6936 means we have no simple and reliable way to continue.
6937 Break out the floating-point parsing into a new
6938 function string_to_number, so that Fstring_to_number parses
6939 floating point numbers consistently with the Lisp reader.
6940 (digit_to_number): Move here from data.c. Make it static inline.
6941 (E_CHAR, EXP_INT): Remove, replacing with ...
6942 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
6943 (string_to_number): New function, replacing isfloat_string.
6944 This function checks for valid syntax and produces the resulting
6945 Lisp float number too. Rework it so that string-to-number
6946 no longer mishandles examples like "1.0e+". Use strtoumax,
6947 so that overflow for non-base-10 numbers is reported only when
6948 there's no portable and simple way to convert to floating point.
6949
6950 * textprop.c (set_text_properties_1): Rewrite for clarity,
6951 and to avoid GCC warning about integer overflow.
6952
6953 * intervals.h (struct interval): Use EMACS_INT for members
6954 where EMACS_UINT might cause problems. See
6955 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
6956 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
6957 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
6958 All uses changed.
6959 (offset_intervals): Tell GCC not to worry about length overflow
6960 when negating a negative length.
6961
6962 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
6963 (overrun_check_free): Likewise.
6964
6965 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
6966 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
6967 word size.
6968
6969 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6970 (gnutls_make_error): Rename local to avoid shadowing.
6971 (gnutls_emacs_global_deinit): ifdef out; not used.
6972 (Fgnutls_boot): Use const for pointer to readonly storage.
6973 Comment out unused local. Fix pointer signedness problems.
6974
6975 * lread.c (openp): Don't stuff size_t into an 'int'.
6976 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
6977 about possible signed overflow.
6978
6979 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6980 (GDK_KEY_g): Don't define if already defined.
6981 (xg_prepare_tooltip): Avoid pointer signedness problem.
6982 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
6983
6984 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
6985 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
6986
6987 * xfns.c (Fx_window_property): Simplify a bit,
6988 to make a bit faster and to avoid GCC 4.6.0 warning.
6989 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
6990
6991 * fns.c (internal_equal): Don't assume size_t fits in int.
6992
6993 * alloc.c (compact_small_strings): Tighten assertion a little.
6994
6995 Replace pEd with more-general pI, and fix some printf arg casts.
6996 * lisp.h (pI): New macro, generalizing old pEd macro to other
6997 conversion specifiers. For example, use "...%"pI"d..." rather
6998 than "...%"pEd"...".
6999 (pEd): Remove. All uses replaced with similar uses of pI.
7000 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
7001 * alloc.c (check_pure_size): Don't overflow by converting size to int.
7002 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
7003 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
7004 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
7005 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
7006 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
7007 64-bit hosts.
7008 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
7009 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
7010 * print.c (safe_debug_print, print_object): Likewise.
7011 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
7012 to int.
7013 Use pI instead of if-then-else-abort. Use %p to avoid casts,
7014 avoiding the 0 flag, which is not portable.
7015 * process.c (Fmake_network_process): Use pI to avoid cast.
7016 * region-cache.c (pp_cache): Likewise.
7017 * xdisp.c (decode_mode_spec): Likewise.
7018 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
7019 behavior on 64-bit hosts with printf arg.
7020 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
7021 (x_stop_queuing_selection_requests): Likewise.
7022 (x_get_window_property): Don't truncate byte count to an 'int'
7023 when tracing.
7024
7025 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
7026 here, since it parses constructs like leading '-' and spaces,
7027 which are not wanted; and it overflows with large numbers.
7028 Instead, simply match F[0-9]+, which is what is wanted anyway.
7029
7030 * alloc.c: Remove unportable assumptions about struct layout.
7031 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
7032 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
7033 (allocate_vectorlike, make_pure_vector): Use the new macros,
7034 plus offsetof, to remove unportable assumptions about struct layout.
7035 These assumptions hold on all porting targets that I know of, but
7036 they are not guaranteed, they're easy to remove, and removing them
7037 makes further changes easier.
7038
7039 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
7040 This doesn't fix a bug but makes the code clearer.
7041 (string_overrun_cookie): Now const. Use initializers that
7042 don't formally overflow signed char, to avoid warnings.
7043 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
7044 can cause Emacs to crash when string overrun checking is enabled.
7045 (allocate_buffer): Don't assume sizeof (struct buffer) is a
7046 multiple of sizeof (EMACS_INT); it need not be, if
7047 alignof(EMACS_INT) < sizeof (EMACS_INT).
7048 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
7049
7050 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
7051
7052 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
7053
7054 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
7055
7056 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
7057 supposed to be handshaking. (Bug#8556)
7058 Reported by Paul Eggert <eggert@cs.ucla.edu>.
7059
7060 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
7061
7062 * lisp.h (Qdebug): List symbol.
7063 * eval.c (Qdebug): Restore global linkage.
7064 * keyboard.c (debug-on-event): New variable.
7065 (handle_user_signal): Break into debugger when debug-on-event
7066 matches the current signal symbol.
7067
7068 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
7069
7070 * alloc.c (check_sblock, check_string_bytes)
7071 (check_string_free_list): Convert to standard C.
7072
7073 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
7074
7075 * w32.c (emacs_gnutls_push): Fix typo.
7076
7077 2011-04-25 Eli Zaretskii <eliz@gnu.org>
7078
7079 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
7080 "cast to pointer from integer of different size".
7081
7082 Improve doprnt and its use in verror. (Bug#8545)
7083 * doprnt.c (doprnt): Document the set of format control sequences
7084 supported by the function. Use SAFE_ALLOCA instead of always
7085 using `alloca'.
7086
7087 * eval.c (verror): Don't limit the buffer size at size_max-1, that
7088 is one byte too soon. Don't use xrealloc; instead xfree and
7089 xmalloc anew.
7090
7091 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
7092
7093 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
7094 callbacks stage.
7095
7096 * gnutls.c: Renamed global_initialized to
7097 gnutls_global_initialized. Added internals for the
7098 :verify-hostname-error, :verify-error, and :verify-flags
7099 parameters of `gnutls-boot' and documented those parameters in the

7924
7925 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
7926
7927 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
7928
7929 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
7930
7931 Fix more problems found by GCC 4.6.0's static checks.
7932
7933 * xdisp.c (vmessage): Use a better test for character truncation.
7934
7935 * charset.c (load_charset_map): <, not <=, for optimization,
7936 and to avoid potential problems with integer overflow.
7937 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
7938 * casetab.c (set_identity, shuffle): Likewise.
7939 * editfns.c (Fformat): Likewise.
7940 * syntax.c (skip_chars): Likewise.
7941
7942 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
7943 This also lets GCC 4.6.0 generate slightly better loop code.
7944
7945 * callint.c (Fcall_interactively): <, not <=, for optimization.
7946 (Fcall_interactively): Count the number of arguments produced,
7947 not the number of arguments given. This is simpler and lets GCC
7948 4.6.0 generate slightly better code.
7949
7950 * ftfont.c: Distingish more carefully between FcChar8 and char.
7951 The previous code passed unsigned char * to a functions like
7952 strlen and xstrcasecmp that expect char *, which does not
7953 conform to the C standard.
7954 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
7955 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
7956 char * when the C standard requires it.
7957
7958 * keyboard.c (read_char): Remove unused var.
7959
7960 * eval.c: Port to Windows vsnprintf (Bug#8435).
7961 Include <limits.h>.
7962 (SIZE_MAX): Define if the headers do not.
7963 (verror): Do not give up if vsnprintf returns a negative count.
7964 Instead, grow the buffer. This ports to Windows vsnprintf, which
7965 does not conform to C99. Problem reported by Eli Zaretskii.
7966 Also, simplify the allocation scheme, by avoiding the need for
7967 calling realloc, and removing the ALLOCATED variable.
7968
7969 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
7970
7971 Remove invocations of doprnt, as Emacs now uses vsnprintf.
7972 But keep the doprint source code for now, as we might revamp it
7973 and use it again (Bug#8435).
7974 * lisp.h (doprnt): Remove.
7975 * Makefile.in (base_obj): Remove doprnt.o.
7976 * deps.mk (doprnt.o): Remove.
7977
7978 error: Print 32- and 64-bit integers portably (Bug#8435).
7979 Without this change, on typical 64-bit hosts error ("...%d...", N)
7980 was used to print both 32- and 64-bit integers N, which relied on
7981 undefined behavior.
7982 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
7983 * lisp.h (error, verror): Mark as printf-like functions.
7984 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
7985 Report overflow in size calculations when allocating printf buffer.
7986 Do not truncate output string at its first null byte.
7987 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
7988 Truncate the output at a character boundary, since vsnprintf does not
7989 do that.
7990 * charset.c (check_iso_charset_parameter): Convert internal
7991 character to string before calling 'error', since %c now has the
7992 printf meaning.
7993 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
7994 overflow when computing char to be passed to 'error'. Do not
7995 pass Lisp_Object to 'error'; pass the integer instead.
7996 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
7997 formatted with plain %d.
7998
7999 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
8000
8001 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
8002
8003 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
8004
8005 * xterm.c (x_catch_errors): Remove duplicate declaration.
8006
8007 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
8008
8009 * xdisp.c, lisp.h (message_nolog): Remove; unused.
8010
8011 2011-04-10 Jim Meyering <meyering@redhat.com>
8012
8013 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
8014 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
8015 return ssize_t not "int", and use size_t as the buffer length.
8016 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
8017 * gnutls.h: Update declarations.
8018 * process.c (read_process_output): Use ssize_t, to match.
8019 (send_process): Likewise.
8020
8021 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
8022
8023 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
8024
8025 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
8026
8027 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
8028 Use unsigned char, to match FcChar8 type definition.
8029
8030 * xterm.c (handle_one_xevent):
8031 * xmenu.c (create_and_show_popup_menu):
8032 * xselect.c (x_decline_selection_request)
8033 (x_reply_selection_request): Avoid type-punned deref of X events.
8034
8035 2011-04-09 Eli Zaretskii <eliz@gnu.org>
8036
8037 Fix some uses of `int' instead of EMACS_INT.
8038 * search.c (string_match_1, fast_string_match)
8039 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
8040 (scan_buffer, find_next_newline_no_quit)
8041 (find_before_next_newline, search_command, Freplace_match)
8042 (Fmatch_data): Make some `int' variables be EMACS_INT.
8043
8044 * xdisp.c (display_count_lines): 3rd argument and return value now
8045 EMACS_INT. All callers changed.
8046 (pint2hrstr): Last argument is now EMACS_INT.
8047
8048 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
8049 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
8050 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
8051 (decode_coding_utf_16, decode_coding_emacs_mule)
8052 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
8053 (decode_coding_ccl, decode_coding_charset)
8054 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
8055 (decode_coding_iso_2022, decode_coding_emacs_mule)
8056 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
8057 <char_offset, last_offset>: Declare EMACS_INT.
8058 (encode_coding_utf_8, encode_coding_utf_16)
8059 (encode_coding_emacs_mule, encode_invocation_designation)
8060 (encode_designation_at_bol, encode_coding_iso_2022)
8061 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
8062 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
8063 Declare EMACS_INT.
8064 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
8065 (encode_invocation_designation): Last argument P_NCHARS is now
8066 EMACS_INT.
8067 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
8068 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
8069
8070 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
8071 All users changed.
8072
8073 * ccl.c (Fccl_execute_on_string): Declare some variables
8074 EMACS_INT.
8075
8076 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
8077
8078 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
8079
8080 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
8081
8082 * process.c (Fformat_network_address): Doc fix.
8083
8084 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
8085
8086 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
8087
8088 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
8089
8090 * keyboard.c (read_char): Call Lisp function help-form-show,
8091 instead of using internal_with_output_to_temp_buffer.
8092 (Qhelp_form_show): New var.
8093 (syms_of_keyboard): Use DEFSYM macro.
8094
8095 * print.c (internal_with_output_to_temp_buffer): Function deleted.
8096
8097 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
8098
8099 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
8100
8101 * process.c (Flist_processes): Remove to Lisp.
8102 (list_processes_1): Delete.
8103
8104 2011-04-06 Eli Zaretskii <eliz@gnu.org>
8105
8106 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
8107
8108 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
8109
8110 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
8111
8112 Fix more problems found by GCC 4.6.0's static checks.
8113
8114 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
8115
8116 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
8117
8118 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
8119
8120 * xdisp.c (vmessage): Mark as a printf-like function.
8121
8122 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
8123
8124 * sound.c (sound_warning): Don't crash if arg contains a printf format.
8125
8126 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
8127 printf-like functions.
8128 (tiff_load): Add casts to remove these marks before passing them
8129 to system-supplied API.
8130
8131 * eval.c (Fsignal): Remove excess argument to 'fatal'.
8132
8133 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
8134 This avoids several warnings with gcc -Wstrict-overflow.
8135 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
8136 directly, rather than having caller test rule sign. This avoids
8137 some unnecessary tests.
8138 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
8139 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
8140 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
8141
8142 * xfont.c (xfont_text_extents): Remove var that was set but not used.
8143 (xfont_open): Avoid unnecessary tests.
8144
8145 * composite.c (composition_gstring_put_cache): Use unsigned integer.

8151 breaking out part of COMPOSITION_DECODE_RULE.
8152 (COMPOSITION_DECODE_RULE): Use it.
8153 * composite.c (get_composition_id): Remove unused local vars,
8154 by using the new macro.
8155
8156 * textprop.c (set_text_properties_1): Change while to do-while,
8157 since the condition is always true at first.
8158
8159 * intervals.c (graft_intervals_into_buffer): Mark var as used.
8160 (interval_deletion_adjustment): Return unsigned value.
8161 All uses changed.
8162
8163 * process.c (list_processes_1, create_pty, read_process_output):
8164 (exec_sentinel): Remove vars that were set but not used.
8165 (create_pty): Remove unnecessary "volatile"s.
8166 (Fnetwork_interface_info): Avoid possibility of int overflow.

8168 (read_process_output): Simplify nbytes computation if buffered.
8169
8170 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
8171
8172 * syntax.c (scan_words): Remove var that was set but not used.
8173 (update_syntax_table): Use unsigned instead of int.
8174
8175 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
8176 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
8177 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
8178
8179 * print.c (print_error_message): Avoid int overflow.
8180
8181 * font.c (font_list_entities): Redo for clarity,
8182 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
8183
8184 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
8185 (font_score): Avoid potential overflow in diff calculation.
8186
8187 * fns.c (substring_both): Remove var that is set but not used.
8188 (sxhash): Redo loop for clarity and to avoid wraparound warning.
8189
8190 * eval.c (funcall_lambda): Rename local to avoid shadowing.
8191
8192 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
8193 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
8194 can always succeed if overflow has undefined behavior.
8195
8196 * search.c (boyer_moore, wordify): Remove vars set but not used.
8197 (wordify): Omit three unnecessary tests.
8198
8199 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
8200 All callers changed. This avoids the need for an unused var.
8201
8202 * casefiddle.c (casify_region): Remove var that is set but not used.
8203
8204 * dired.c (file_name_completion): Remove var that is set but not used.
8205
8206 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
8207
8208 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
8209 (Finsert_file_contents): Remove unnecessary code checking fd.
8210
8211 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
8212 Check for integer overflow on size calculations.
8213
8214 * buffer.c (Fprevious_overlay_change): Remove var that is set
8215 but not used.
8216
8217 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
8218 Remove vars that are set but not used.
8219 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
8220 (timer_check_2): Mark vars as initialized.
8221
8222 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
8223
8224 * image.c (lookup_image): Remove var that is set but not used.
8225 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
8226
8227 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
8228 that are set but not used.
8229
8230 * xfns.c (make_invisible_cursor): Don't return garbage
8231 if XCreateBitmapFromData fails (Bug#8410).
8232
8233 * xselect.c (x_get_local_selection, x_handle_property_notify):
8234 Remove vars that are set but not used.
8235
8236 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

8240 Remove var that is set but not used.
8241 (scroll_bar_windows_size): Now size_t, not int.
8242 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
8243 Check for overflow.
8244
8245 * xfaces.c (realize_named_face): Remove vars that are set but not used.
8246 (map_tty_color) [!defined MSDOS]: Likewise.
8247
8248 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
8249
8250 * coding.c: Remove vars that are set but not used.
8251 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
8252 All callers changed.
8253 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
8254 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
8255 (decode_coding_charset): Remove vars that are set but not used.
8256
8257 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
8258 that is set but not used.
8259
8260 * print.c (print_object): Remove var that is set but not used.
8261
8262 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
8263 The gnulib version avoids calling malloc in the usual case,
8264 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
8265 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
8266 * filelock.c (current_lock_owner): Likewise.
8267 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
8268 * sysdep.c: Include allocator.h, careadlinkat.h.
8269 (emacs_no_realloc_allocator): New static constant.
8270 (emacs_readlink): New function.
8271 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
8272 ../lib/careadlinkat.h.
8273
8274 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
8275
8276 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
8277 first non-nil return value).
8278

8280
8281 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

8285
8286 * xdisp.c (display_count_lines): Remove parameter `start',
8287 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

8289 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
8290 (fill_stretch_glyph_string): Remove parameters `row' and `area',
8291 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
8292 and thereabouts. All callers changed.
8293 (get_per_char_metric): Remove parameter `f', unused since
8294 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

8307
8308 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
8309 later (Bug#8403).

8346 (Ffunctionp): Move from subr.el.
8347 (Ffuncall): Handle closures.
8348 (apply_lambda): Remove `eval_flags'.
8349 (funcall_lambda): Handle closures and new byte-code-functions.
8350 (Fspecial_variable_p): New function.
8351 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
8352 but without exporting it to Lisp.
8353
8354 * doc.c (Fdocumentation, store_function_docstring):
8355 * data.c (Finteractive_form): Handle closures.
8356
8357 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
8358 interactive spec.
8359
8360 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
8361 New byte-codes.
8362 (exec_byte_code): New function extracted from Fbyte_code to handle new
8363 calling convention for byte-code-functions. Add new byte-codes.
8364
8365 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
8366
8367 * alloc.c (Fmake_symbol): Init new `declared_special' field.
8368
8369 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
8370
8371 * xdisp.c (redisplay_internal): Fix prototype.
8372
8373 2011-03-31 Eli Zaretskii <eliz@gnu.org>
8374
8375 * xdisp.c (SCROLL_LIMIT): New macro.
8376 (try_scrolling): Use it when setting scroll_limit.
8377 Limit scrolling to 100 screen lines.
8378 (redisplay_window): Even when falling back on "recentering",
8379 position point in the window according to scroll-conservatively,
8380 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
8381
8382 (try_scrolling): When point is above the window, allow searching
8383 as far as scroll_max, or one screenful, to compute vertical
8384 distance from PT to the scroll margin position. This prevents
8385 try_scrolling from unnecessarily failing when
8386 scroll-conservatively is set to a value slightly larger than the
8387 window height. Clean up the case of PT below the margin at bottom
8388 of window: scroll_max can no longer be INT_MAX. When aggressive
8389 scrolling is in use, don't let point enter the opposite scroll
8390 margin as result of the scroll.
8391 (syms_of_xdisp) <scroll-conservatively>: Document the
8392 threshold of 100 lines for never-recentering scrolling.
8393
8394 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
8395
8396 * dispextern.h (move_it_by_lines):
8397 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
8398 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
8399 (message_log_check_duplicate): Remove parameters `prev_bol' and
8400 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
8401 (redisplay_internal): Remove parameter `preserve_echo_area',
8402 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
8403
8404 * indent.c (Fvertical_motion):
8405 * window.c (window_scroll_pixel_based, Frecenter):
8406 Don't pass `need_y_p' to `move_it_by_lines'.
8407
8408 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
8409
8410 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
8411 steal a few bits to be more compact.
8412 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
8413 Remove unneeded casts.
8414
8415 * bytecode.c (Fbyte_code): CAR and CDR can GC.
8416
8417 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
8418
8419 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
8420 binding" message (bug#7967).
8421
8422 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
8423
8424 Fix more problems found by GCC 4.6.0's static checks.
8425
8426 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
8427 Remove unused local var.
8428
8429 * editfns.c (Fmessage_box): Remove unused local var.
8430
8431 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
8432 (note_mode_line_or_margin_highlight, note_mouse_highlight):
8433 Omit unused local vars.
8434 * window.c (shrink_windows): Omit unused local var.
8435 * menu.c (digest_single_submenu): Omit unused local var.
8436 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
8437 Omit unused local var.
8438
8439 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
8440 Don't assume string length fits in int.
8441 (keyremap_step, read_key_sequence): Use size_t for sizes.
8442 (read_key_sequence): Don't check last_real_key_start redundantly.
8443
8444 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
8445 instead of alloca (Bug#8344).
8446
8447 * eval.c (Fbacktrace): Don't assume nargs fits in int.
8448 (Fbacktrace_frame): Don't assume nframes fits in int.
8449
8450 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
8451
8452 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
8453 concerns.
8454
8455 * term.c (produce_glyphless_glyph): Remove unnecessary test.
8456
8457 * cm.c (calccost): Turn while-do into do-while, for clarity.
8458
8459 * keyboard.c (syms_of_keyboard): Use the same style as later
8460 in this function when indexing through an array. This also
8461 works around GCC bug 48267.
8462
8463 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
8464
8465 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
8466
8467 * chartab.c (sub_char_table_ref_and_range): Redo for slight
8468 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
8469
8470 * keyboard.c, keyboard.h (num_input_events): Now size_t.
8471 This avoids undefined behavior on integer overflow, and is a bit
8472 more convenient anyway since it is compared to a size_t variable.
8473
8474 Variadic C functions now count arguments with size_t, not int.
8475 This avoids an unnecessary limitation on 64-bit machines, which
8476 caused (substring ...) to crash on large vectors (Bug#8344).
8477 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
8478 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
8479 All variadic functions and their callers changed accordingly.

8481 * data.c (arith_driver, float_arith_driver): Likewise.
8482 * editfns.c (general_insert_function): Likewise.
8483 * eval.c (struct backtrace.nargs, interactive_p)
8484 (internal_condition_case_n, run_hook_with_args, apply_lambda)
8485 (funcall_lambda, mark_backtrace): Likewise.
8486 * fns.c (concat): Likewise.
8487 * frame.c (x_set_frame_parameters): Likewise.
8488 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
8489 0 if not found, not -1. All callers changed.
8490
8491 * alloc.c (garbage_collect): Don't assume stack size fits in int.
8492 (stack_copy_size): Now size_t, not int.
8493 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
8494

8498 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
8499 All callers changed.
8500
8501 * lisp.h (multibyte_char_to_unibyte):
8502 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
8503 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
8504 * character.h (CHAR_TO_BYTE8):
8505 * cmds.c (internal_self_insert):
8506 * editfns.c (general_insert_function):
8507 * keymap.c (push_key_description):
8508 * search.c (Freplace_match):
8509 * xdisp.c (message_dolog, set_message_1): All callers changed.
8510
8511 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8512
8513 * keyboard.c (safe_run_hook_funcall): New function.
8514 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
8515 don't set the hook to nil, but remove the offending function instead.
8516 (Qcommand_hook_internal): Remove, unused.
8517 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
8518 Vcommand_hook_internal.
8519
8520 * eval.c (enum run_hooks_condition): Remove.
8521 (funcall_nil, funcall_not): New functions.
8522 (run_hook_with_args): Call each function through a `funcall' argument.
8523 Remove `cond' argument, now redundant.
8524 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
8525 (Frun_hook_with_args_until_failure): Adjust accordingly.
8526 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
8527
8528 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
8529
8530 * dispextern.h (string_buffer_position): Remove declaration.
8531
8532 * print.c (strout): Remove parameter `multibyte', unused since
8533 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
8534
8535 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
8536 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
8537 All callers changed.
8538
8539 * w32.c (_wsa_errlist): Use braces for struct initializers.
8540
8541 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

8545 used outside xdisp.c).
8546 (cursor_row_p): Remove parameter `w', unused since
8547 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

8565 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
8566
8567 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
8568
8569 * nsmenu.m (runDialogAt): Remove argument to timer_check.
8570

8579
8580 2011-03-26 Eli Zaretskii <eliz@gnu.org>
8581
8582 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
8583 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
8584
8585 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
8586
8587 * w32.c (read_unc_volume): Use parameter `henum', instead of
8588 global variable `wget_enum_handle'.
8589
8590 * keymap.c (describe_vector): Remove parameters `indices' and
8591 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
8592 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
8593
8594 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
8595
8596 * keyboard.c (timer_check): Remove parameter `do_it_now',
8597 unused since 1996-04-12T06:01:29Z!rms@gnu.org.

8599 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
8600
8601 * keyboard.c (read_char):
8602 * w32menu.c (w32_menu_display_help):
8603 * xmenu.c (show_help_event, menu_help_callback):
8604 Adjust calls to `show_help_echo'.
8605
8606 * gtkutil.c (xg_maybe_add_timer):
8607 * keyboard.c (readable_events):
8608 * process.c (wait_reading_process_output):
8609 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
8610

8663
8664 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
8665
8666 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
8667 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
8668 (Fx_close_connection): Remove unused variable `i'.
8669
8670 * w32font.c (w32font_draw): Return number of glyphs.
8671 (w32font_open_internal): Remove unused variable `i'.
8672 (w32font_driver): Add missing initializer.
8673
8674 * w32menu.c (utf8to16): Remove unused variable `utf16'.

8676
8677 * w32term.c (last_mouse_press_frame): Remove static global variable.
8678 (w32_clip_to_row): Remove unused variable `f'.
8679 (x_delete_terminal): Remove unused variable `i'.
8680
8681 * w32uniscribe.c (uniscribe_shape): Remove unused variable `nclusters'.

8683 (uniscribe_check_otf): Remove unused variable `table'.
8684 (uniscribe_font_driver): Add missing initializers.
8685
8686 2011-03-23 Julien Danjou <julien@danjou.info>
8687
8688 * term.c (Fsuspend_tty, Fresume_tty):
8689 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
8690 * window.c (temp_output_buffer_show):
8691 * insdel.c (signal_before_change):
8692 * frame.c (Fhandle_switch_frame):
8693 * fileio.c (Fdo_auto_save):
8694 * emacs.c (Fkill_emacs):
8695 * editfns.c (save_excursion_restore):
8696 * cmds.c (internal_self_insert):
8697 * callint.c (Fcall_interactively):
8698 * buffer.c (Fkill_all_local_variables):
8699 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
8700 Use Frun_hooks.
8701 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
8702 unconditionally since it does the check itself.
8703
8704 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
8705
8706 Fix more problems found by GCC 4.5.2's static checks.
8707
8708 * coding.c (encode_coding_raw_text): Avoid unnecessary test
8709 the first time through the loop, since we know p0 < p1 then.
8710 This also avoids a gcc -Wstrict-overflow warning.
8711
8712 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
8713 leading to a memory leak, possible in functions like
8714 load_charset_map_from_file that can allocate an unbounded number
8715 of objects (Bug#8318).
8716
8717 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
8718 that could (at least in theory) be that large.
8719
8720 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
8721 This is less likely to overflow, and avoids undefined behavior if
8722 overflow does occur. All callers changed. Use strtoul to scan
8723 for the unsigned long integer.
8724 (pint2hrstr): Simplify and tune code slightly.
8725 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
8726
8727 * scroll.c (do_scrolling): Work around GCC bug 48228.
8728 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
8729
8730 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
8731 This also avoids a warning with gcc -Wstrict-overflow.
8732 (validate_x_resource_name): Simplify count usage.
8733 This also avoids a warning with gcc -Wstrict-overflow.
8734
8735 * fileio.c (Fcopy_file): Report error if fchown or fchmod
8736 fail (Bug#8306).
8737
8738 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
8739
8740 * process.c (Fmake_network_process): Use socklen_t, not int,
8741 where POSIX says socklen_t is required in portable programs.
8742 This fixes a porting bug on hosts like 64-bit HP-UX, where
8743 socklen_t is wider than int (Bug#8277).
8744 (Fmake_network_process, server_accept_connection):
8745 (wait_reading_process_output, read_process_output):
8746 Likewise.
8747
8748 * process.c: Rename or move locals to avoid shadowing.
8749 (list_processes_1, Fmake_network_process):
8750 (read_process_output_error_handler, exec_sentinel_error_handler):
8751 Rename or move locals.
8752 (Fmake_network_process): Define label "retry_connect" only if needed.
8753 (Fnetwork_interface_info): Fix pointer signedness.

8764 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
8765 (tparam): Adjust signature to match interface in tparam.h;
8766 this removes some undefined behavior. Check that outstring and len
8767 are zero, which they always are with Emacs.

8825 This should get cleaned up, so that child_setup has the
8826 same signature on all platforms.
8827
8828 * callproc.c (call_process_cleanup): Now static.
8829 (relocate_fd): Rename locals to avoid shadowing.

8831 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
8832
8833 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
8834 not to be necessary, and produces flickering.
8835

8958 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
8959 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,

8990 (Fmemory_limit): Cast sbrk's returned value to char *.
8991

8995 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
8996
8997 Use functions, not macros, for up- and down-casing (Bug#8254).
8998 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8999 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
9000 to use the following functions instead of these macros.
9001 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
9002 EMACS_INT, since callers assume the returned value fits in int.

9005 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

9011 (regex_compile, re_search_2, re_match_2_internal):
9012 Remove unused local vars.

9015 (regex_compile, re_match_2_internal): Mark locals as initialized.
9016 (RETALLOC_IF): Define only if needed.
9017 (WORDCHAR_P): Likewise. This one is never needed, but is used
9018 only in a comment talking about a compiler bug, so put inside
9019 the #if 0 of that comment.
9020 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
9021 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

9046
9047 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
9048 New macros, so that the caller can use some names other than
9049 gcpro1, gcpro2, etc.
9050 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
9051 of the new macros.
9052 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
9053 argument, for consistency with GCPRO2_VAR, etc: it is now the
9054 prefix of the variable, not the variable itself. All uses
9055 changed.

9057 Rename locals to avoid shadowing.
9058
9059 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
9060 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
9061 dired.c's scmp function, had undefined behavior.
9062 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
9063 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
9064 * buffer.h: ... to here, because these macros use current_buffer,
9065 and the new implementation with inline functions needs to have
9066 current_buffer in scope now, rather than later when the macros
9067 are used.
9068 (downcase, upcase1): New static inline functions.
9069 (DOWNCASE, UPCASE1): Reimplement using these functions.
9070 This avoids undefined behavior in expressions like
9071 DOWNCASE (x) == DOWNCASE (y), which previously suffered
9072 from race conditions in accessing the global variables
9073 case_temp1 and case_temp2.
9074 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
9075 * lisp.h (case_temp1, case_temp2): Remove their decls.
9076 * character.h (ASCII_CHAR_P): Move from here ...
9077 * lisp.h: ... to here, so that the inline functions mentioned

9080 * dired.c (directory_files_internal_unwind): Now static.
9081
9082 * fileio.c (file_name_as_directory, directory_file_name):

9084 Now static.
9085 (file_name_as_directory): Use const pointers when appropriate.
9086 (Fexpand_file_name): Likewise. In particular, newdir might

9089 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
9090 signedness issues.

9096 to avoid shadowing.
9097
9098 * marker.c (bytepos_to_charpos): Remove; unused.
9099
9100 * lisp.h (verify_bytepos, count_markers): New decls,
9101 so that gcc does not warn that these functions aren't declared.
9102
9103 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
9104 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

9106 (copy_text): Remove unused local var.
9107
9108 * filelock.c (within_one_second): Now static.
9109 (lock_file_1): Rename local to avoid shadowing.
9110
9111 * buffer.c (fix_overlays_before): Mark locals as initialized.
9112 (fix_start_end_in_overlays): Likewise. This function should be
9113 simplified by using pointers-to-pointers, but that's a different
9114 matter.
9115 (switch_to_buffer_1): Now static.
9116 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
9117 (report_overlay_modification): Rename locals to avoid shadowing.
9118
9119 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
9120 Fix pointer signedness issue.
9121 (sys_subshell): Mark local as volatile if checking for lint,
9122 to suppress a gcc -Wclobbered warning that does not seem to be right.
9123 (MAXPATHLEN): Define only if needed.
9124
9125 * process.c (serial_open, serial_configure): Move decls from here ...
9126 * systty.h: ... to here, so that they can be checked.
9127
9128 * fns.c (get_random, seed_random): Move extern decls from here ...
9129 * lisp.h: ... to here, so that they can be checked.

9133
9134 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

9136 Now static.
9137 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
9138 (DENSE_TABLE_SIZE): Remove; unused.

9147 (make_lispy_event, make_lispy_movement, apply_modifiers):
9148 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

9159
9160 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
9161 (DEFINE_DUMMY_FUNCTION): New macro.

9165 if GCC considers string literals to be constants.
9166
9167 * lisp.h (fatal_error_signal): Add decl, since it's exported.
9168
9169 * dbusbind.c: Pointer signedness fixes.
9170 (xd_signature, xd_append_arg, xd_initialize):
9171 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9172 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9173 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
9174 (Fdbus_register_signal): Use SSDATA when the context wants char *.
9175
