91 * xterm.h: ... here, so that it can be checked for consistency.
92
93 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
94

108
109 2011-05-28 Jim Meyering <meyering@redhat.com>
110
111 Avoid a sign-extension bug in crypto_hash_function.
112 * fns.c (to_uchar): Define.
113 (crypto_hash_function): Use it to convert some newly-signed
114 variables to unsigned, to avoid sign-extension bugs. For example,
115 without this change, (md5 "truc") would evaluate to
116 45723a2aff78ff4fff7fff1114760e62 rather than the expected
117 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
118 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
119
120 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
121
122 Integer overflow fixes.
123
124 * dbusbind.c: Serial number integer overflow fixes.
125 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
126 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
127 to hold a serial number that is too large for a fixnum.
128 (Fdbus_method_return_internal, Fdbus_method_error_internal):
129 Check for serial numbers out of range. Decode any serial number
130 that was so large that it became a float. (Bug#8722)
131
132 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
133 (Fdbus_call_method, Fdbus_call_method_asynchronously):
134 Use XFASTINT rather than XUINT when numbers are nonnegative.
135 (xd_append_arg, Fdbus_method_return_internal):
136 (Fdbus_method_error_internal): Likewise. Also, for unsigned
137 arguments, check that Lisp number is nonnegative, rather than
138 silently wrapping negative numbers around. (Bug#8722)
139 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
140 (Bug#8722)
141
142 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
143
144 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
145
146 ccl: add integer overflow checks
147 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
148 (IN_INT_RANGE): New macros.
149 (ccl_driver): Use them to check for integer overflow when
150 decoding a CCL program. Many of the new checks are whether XINT (x)
151 fits in int; it doesn't always, on 64-bit hosts. The new version
152 doesn't catch all possible integer overflows, but it's an
153 improvement. (Bug#8719)
154
155 * alloc.c (make_event_array): Use XINT, not XUINT.
156 There's no need for unsigned here.
157
158 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
159 This follows up to the 2011-05-06 change that substituted uintptr_t
160 for EMACS_INT. This case wasn't caught back then.
161
162 Rework Fformat to avoid integer overflow issues.
163 * editfns.c: Include <float.h> unconditionally, as it's everywhere
164 now (part of C89). Include <verify.h>.
165 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
166 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
167 (Fformat): Avoid the prepass trying to compute sizes; it was only
168 approximate and thus did not catch overflow reliably. Instead, walk
169 through the format just once, formatting and computing sizes as we go,
170 checking for integer overflow at every step, and allocating a larger
171 buffer as needed. Keep track separately whether the format is
172 multibyte. Keep only the most-recently calculated precision, rather
173 than them all. Record whether each argument has been converted to
174 string. Use EMACS_INT, not int, for byte and char and arg counts.
175 Support field widths and precisions larger than INT_MAX. Avoid
176 sprintf's undefined behavior with conversion specifications such as %#d
177 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
178 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
179 formatting out-of-range floating point numbers with int
180 formats. (Bug#8668)
181
182 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
183
184 * data.c: Avoid integer truncation in expressions involving floats.
185 * data.c: Include <intprops.h>.
186 (arith_driver): When there's an integer overflow in an expression
187 involving floating point, convert the integers to floating point
188 so that the resulting value does not suffer from catastrophic
189 integer truncation. For example, on a 64-bit host (* 4
190 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
191 Do not rely on undefined behavior after integer overflow.
192
193 merge count_size_as_multibyte, parse_str_to_multibyte
194 * character.c, character.h (count_size_as_multibyte):
195 Rename from parse_str_to_multibyte; all uses changed.
196 Check for integer overflow.
197 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
198 since it's now a duplicate of the other. This is more of
199 a character than a buffer op, so better that it's in character.c.
200 * fns.c, print.c: Adjust to above changes.
201
202 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
203
204 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
205
206 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
207
208 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
209 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
210 (x_clipboard_manager_save): Now static.
211 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
212
213 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
214 (crypto_hash_function): Now static.
215 Fix pointer signedness problems. Avoid unnecessary initializations.
216
217 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
218
219 * termhooks.h (Vselection_alist): Make it terminal-local.
220
221 * terminal.c (create_terminal): Initialize it.
222
223 * xselect.c: Support for clipboard managers.
224 (Vselection_alist): Move to termhooks.h as terminal-local var.
225 (LOCAL_SELECTION): New macro.
226 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
227 (symbol_to_x_atom): Remove gratuitous arg.
228 (x_handle_selection_request, lisp_data_to_selection_data)
229 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
230 (x_own_selection, x_get_local_selection, x_convert_selection):
231 New arg, specifying work frame. Use terminal-local Vselection_alist.
232 (some_frame_on_display): Delete unused function.
233 (Fx_own_selection_internal, Fx_get_selection_internal)
234 (Fx_disown_selection_internal, Fx_selection_owner_p)
235 (Fx_selection_exists_p): New optional frame arg.
236 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
237 (x_handle_selection_clear): Don't treat other terminals with the
238 same keyboard specially. Use the terminal-local Vselection_alist.
239 (x_clear_frame_selections): Use Frun_hook_with_args.
240
241 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
242
243 * xterm.h: Add support for those atoms.
244
245 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
246
247 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
248 (converted_selections, conversion_fail_tag): New global variables.
249 (x_selection_request_lisp_error): Free the above.
250 (x_get_local_selection): Remove unnecessary code.
251 (x_reply_selection_request): Args changed; handle arbitrary array
252 of converted selections stored in converted_selections.
253 Separate the XChangeProperty and SelectionNotify steps.
254 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
255 (x_convert_selection): New function.
256 (x_handle_selection_event): Simplify.
257 (x_get_foreign_selection): Don't ignore incoming requests while
258 waiting for an answer; this will fail when we implement
259 SAVE_TARGETS, and seems unnecessary anyway.
260 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
261 (Vx_sent_selection_functions): Doc fix.
262
263 2011-05-26 Leo Liu <sdl.web@gmail.com>
264
265 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
266
267 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
268
269 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
270
271 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
272 for fringe update if it has periodic bitmap.
273 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
274 and fringe_bitmap_periodic_p.
275
276 * fringe.c (get_fringe_bitmap_data): New function.
277 (draw_fringe_bitmap_1, update_window_fringes): Use it.
278 (update_window_fringes): Record periodicity of fringe bitmap in glyph
279 row. Mark glyph row for fringe update if periodicity changed.
280
281 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
282 for fringe update unless it has periodic bitmap.
283
284 2011-05-25 Kenichi Handa <handa@m17n.org>
285
286 * xdisp.c (get_next_display_element): Set correct it->face_id for
287 a static composition.
288
289 2011-05-24 Leo Liu <sdl.web@gmail.com>
290
291 * deps.mk (fns.o):
292 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
293
294 * fns.c (crypto_hash_function, Fsha1): New function.
295 (Fmd5): Use crypto_hash_function.
296 (syms_of_fns): Add Ssha1.
297
298 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
299
300 * gnutls.c: Remove unused macros.
301 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
302 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
303 Remove macros that are defined and never used.
304 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
305
306 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
307
308 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
309 (Fx_get_selection_internal): Minor cleanup.
310 (Fx_own_selection_internal): Rename arguments for consistency with
311 select.el.
312
313 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
314
315 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
316
317 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
318
319 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
320
321 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
322
323 * dispnew.c (scrolling_window): Don't exclude the case that the
324 last enabled row in the desired matrix touches the bottom boundary.
325
326 2011-05-21 Glenn Morris <rgm@gnu.org>
327
328 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
329 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
330 and add some more files.
331
332 2011-05-20 Eli Zaretskii <eliz@gnu.org>
333
334 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
335 report_file_error introduced by the change from 2011-05-07.
336
337 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
338
339 * systime.h (Time): Define only if emacs is defined.
340 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
341 where the include path doesn't have X11/X.h by default. See
342 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
343
344 2011-05-20 Kenichi Handa <handa@m17n.org>
345
346 * composite.c (find_automatic_composition): Fix previous change.
347
348 2011-05-20 Glenn Morris <rgm@gnu.org>
349
350 * lisp.mk: New file, split from Makefile.in.
351 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
352 (shortlisp): Remove.
353 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
354
355 2011-05-19 Glenn Morris <rgm@gnu.org>
356
357 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
358 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
359 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
360 (lisp): Set the order to that of loadup.el.
361 (shortlisp): Make it a copy of $lisp.
362 (SOME_MACHINE_LISP): Remove.
363 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
364 Use just $shortlisp, not $SOME_MACHINE_LISP too.
365
366 2011-05-18 Kenichi Handa <handa@m17n.org>
367
368 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
369 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
370 (find_automatic_composition): Mostly rewrite for efficiency.
371
372 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
373
374 * makefile.w32-in: Update dependencies.
375
376 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
377
378 * menu.c: Include limits.h (fixes the MS-Windows build broken by
379 revision 104625).
380
381 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
382
383 Fix some integer overflow issues, such as string length overflow.
384
385 * insdel.c (count_size_as_multibyte): Check for string overflow.
386
387 * character.c (lisp_string_width): Check for string overflow.
388 Use EMACS_INT, not int, for string indexes and lengths; in
389 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
390 the resulting string length overflows an EMACS_INT; instead,
391 report a string overflow if no precision given. When checking for
392 precision exhaustion, use a check that cannot possibly have
393 integer overflow. (Bug#8675)
394 * character.h (lisp_string_width): Adjust to new signature.
395
396 * alloc.c (string_overflow): New function.
397 (Fmake_string): Use it. This doesn't change behavior, but saves
398 a few bytes and will simplify future changes.
399 * character.c (string_escape_byte8): Likewise.
400 * lisp.h (string_overflow): New decl.
401
402 Fixups, following up to the user-interface timestamp change.
403 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
404 for UI timestamps, instead of unsigned long.
405 * msdos.c (mouse_get_pos): Likewise.
406 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
407 * w32gui.h (Time): Define by including "systime.h" rather than by
408 declaring it ourselves. (Bug#8664)
409
410 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
411 * image.c (clear_image_cache): Likewise.
412
413 * term.c (term_mouse_position): Don't assume time_t wraparound.
414
415 Be more systematic about user-interface timestamps.
416 Before, the code sometimes used 'Time', sometimes 'unsigned long',
417 and sometimes 'EMACS_UINT', to represent these timestamps.
418 This change causes it to use 'Time' uniformly, as that's what X uses.
419 This makes the code easier to follow, and makes it easier to catch
420 integer overflow bugs such as Bug#8664.
421 * frame.c (Fmouse_position, Fmouse_pixel_position):
422 Use Time, not unsigned long, for user-interface timestamps.
423 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
424 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
425 * keyboard.h (last_event_timestamp): Likewise.
426 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
427 * menu.h (xmenu_show): Likewise.
428 * term.c (term_mouse_position): Likewise.
429 * termhooks.h (struct input_event.timestamp): Likewise.
430 (struct terminal.mouse_position_hook): Likewise.
431 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
432 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
433 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
434 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
435 what it was before.
436 * menu.h, termhooks.h: Include "systime.h", for Time.
437
438 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
439 Don't assume that the difference between two unsigned long values
440 can fit into an integer. At this point, we know button_down_time
441 <= event->timestamp, so the difference must be nonnegative, so
442 there's no need to cast the result if double-click-time is
443 nonnegative, as it should be; check that it's nonnegative, just in
444 case. This bug is triggered when events are more than 2**31 ms
445 apart (about 25 days). (Bug#8664)
446
447 * xselect.c (last_event_timestamp): Remove duplicate decl.
448 (x_own_selection): Remove needless cast to unsigned long.
449
450 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
451 that always fit in int. Use a sentinel instead of a counter, to
452 avoid a temp and to allay GCC's concerns about possible int overflow.
453 * frame.h (struct frame): Use int for menu_bar_items_used
454 instead of EMACS_INT, since it always fits in int.
455
456 * menu.c (grow_menu_items): Check for int overflow.
457
458 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
459
460 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
461 Before, the code was not consistent. These values cannot exceed
462 2**31 - 1 so there's no need to make them unsigned.
463 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
464 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
465 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
466 as modifiers.
467 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
468
469 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
470 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
471 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
472 presumably because the widths might not match.
473
474 * window.c (size_window): Avoid needless test at loop start.
475
476 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
477
478 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
479
480 2011-05-12 Drew Adams <drew.adams@oracle.com>
481
482 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
483
484 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
485
486 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
487 `width' to `bar_area_x' and `bar_area_width', respectively.
488 (x_scroll_run): Take account of fringe background extension.
489
490 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
491 Rename local vars `left' and `width' to `bar_area_x' and
492 `bar_area_width', respectively.
493 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
494 background extension.
495
496 2011-05-10 Jim Meyering <meyering@redhat.com>
497
498 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
499
500 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
501
502 * image.c (Finit_image_library): Return t for built-in image types,
503 like pbm and xbm. (Bug#8640)
504
505 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
506
507 * w32menu.c (set_frame_menubar): Fix submenu allocation.
508
509 2011-05-07 Eli Zaretskii <eliz@gnu.org>
510
511 * w32console.c (Fset_screen_color): Doc fix.
512 (Fget_screen_color): New function.
513 (syms_of_ntterm): Defsubr it.
514
515 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
516 unlink the temporary file if Fcall_process didn't create it in the
517 first place.
518 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
519 child process will be redirected to a file specified with `:file'.
520 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
521 cue to call_process_cleanup not to close that handle.
522
523 2011-05-07 Ben Key <bkey76@gmail.com>
524
525 * makefile.w32-in: The bootstrap-temacs rule now makes use of
526 one of two shell specific rules, either bootstrap-temacs-CMD or
527 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
528 to the previous implementation of the bootstrap-temacs rule.
529 The bootstrap-temacs-CMD rule is similar to the previous
530 implementation of the bootstrap-temacs rule except that it
531 makes use of the ESC_CFLAGS variable instead of the CFLAGS
532 variable.
533
534 These changes, along with some changes to nt/configure.bat,
535 nt/gmake.defs, and nt/nmake.defs, are required to extend my
536 earlier fix to add support for --cflags and --ldflags options
537 that include quotes so that it works whether make uses cmd or
538 sh as the shell.
539
540 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
541
542 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
543 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
544 is a constant.
545 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
546 a string. Handle both cases.
547 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
548 (Fdbus_register_method): Use Qinvalid_function.
549
550 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
551
552 * makefile.w32-in: Update dependencies.
553 (LISP_H): Add inttypes.h and stdin.h.
554 (PROCESS_H): Add unistd.h.
555
556 2011-05-06 Eli Zaretskii <eliz@gnu.org>
557
558 * lread.c: Include limits.h (fixes the MS-Windows build broken by
559 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
560
561 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
562
563 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
564
565 * term.c (vfatal): Remove stray call to va_end.
566 It's not needed and the C Standard doesn't allow it here anyway.
567
568 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
569 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
570
571 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
572 bytes.
573
574 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
575
576 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
577
578 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
579
580 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
581
582 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
583
584 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
585 * charset.c (Fdefine_charset_internal): Don't initialize
586 charset.code_space[15]. The value was garbage, on hosts with
587 32-bit int (Bug#8600).
588
589 * lread.c (read_integer): Be more consistent with string-to-number.
590 Use string_to_number to do the actual conversion; this avoids
591 rounding errors and fixes some other screwups. Without this fix,
592 for example, #x1fffffffffffffff was misread as -2305843009213693952.
593 (digit_to_number): Move earlier, for benefit of read_integer.
594 Return -1 if the digit is out of range for the base, -2 if it is
595 not a digit in any supported base. (Bug#8602)
596
597 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
598
599 * dispnew.c (scrolling_window): Return 1 if we scrolled,
600 to match comment at start of function. This also removes a
601 GCC warning about overflow in a 32+64-bit port.
602
603 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
604
605 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
606 Reported by Stefan Monnier in
607 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
608 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
609 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
610
611 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
612 (EMACS_UINTPTR): Likewise, with uintptr_t.
613
614 * lisp.h: Prefer 64-bit EMACS_INT if available.
615 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
616 on 32-bit hosts that have 64-bit int, so that they can access
617 large files.
618 However, temporarily disable this change unless the temporary
619 symbol WIDE_EMACS_INT is defined.
620
621 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
622
623 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
624 This removes an assumption that EMACS_INT and long are the same
625 width as pointers. The assumption is true for Emacs porting targets
626 now, but we want to make other targets possible.
627 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
628 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
629 In the rest of the code, change types of integers that hold casted
630 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
631 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
632 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
633 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
634 No need to cast type when ORing.
635 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
636 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
637 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
638 assume EMACS_INT is the same width as char *.
639 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
640 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
641 Remove no-longer-needed casts.
642 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
643 (xg_tool_bar_help_callback, xg_make_tool_item):
644 Use EMACS_INTPTR to hold an integer
645 that will be cast to void *; this can avoid a GCC warning
646 if EMACS_INT is not the same width as void *.
647 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
648 * xdisp.c (display_echo_area_1, resize_mini_window_1):
649 (current_message_1, set_message_1):
650 Use a local to convert to proper width without a cast.
651 * xmenu.c (dialog_selection_callback): Likewise.
652
653 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
654 Also, don't assume VALBITS / RAND_BITS is less than 5,
655 and don't rely on undefined behavior when shifting a 1 left into
656 the sign bit.
657 * lisp.h (get_random): Change signature to match.
658
659 * lread.c (hash_string): Use size_t, not int, for hash computation.
660 Normally we prefer signed values; but hashing is special, because
661 it's better to use unsigned division on hash table sizes so that
662 the remainder is nonnegative. Also, size_t is the natural width
663 for hashing into memory. The previous code used 'int', which doesn't
664 retain enough info to hash well into very large tables.
665 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
666
667 * dbusbind.c: Don't possibly lose pointer info when converting.
668 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
669 Use XPNTR rather than XHASH, so that the high-order bits of
670 the pointer aren't lost when converting through void *.
671
672 * eval.c (Fautoload): Don't double-shift a pointer.
673
674 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
675
676 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
677
678 * gnutls.c (DEF_GNUTLS_FN):
679 * image.c (DEF_IMGLIB_FN): Make function pointers static.
680
681 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
682
683 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
684 marker. (Bug#8610)
685
686 2011-05-05 Eli Zaretskii <eliz@gnu.org>
687
688 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
689 New version that can reserve upto 2GB of heap space.
690
691 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
692
693 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

696
697 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
698 `gnutls_certificate_set_x509_key_file'.
699

702 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
703 Update dependencies.
704

706
707 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
708 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
709 Remove unused parameter `fildes'.
710 * process.c (read_process_output, send_process): Don't pass it.
711
712 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
713
714 Fix previous change: the library cache is defined in w32.c.
715 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
716 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
717
718 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
719
720 Implement dynamic loading of GnuTLS on Windows.
721
722 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
723 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
724 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
725 Declare.
726
727 * gnutls.c (Qgnutls_dll): Define.
728 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
729 (gnutls_*): Declare function pointers.
730 (init_gnutls_functions): New function to initialize function pointers.
731 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
732 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
733 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
734 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
735 (emacs_gnutls_write, emacs_gnutls_read)
736 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
737 (Fgnutls_available_p): New function.
738 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
739 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
740 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
741
742 * image.c: Include w32.h.
743 (Vimage_type_cache): Delete.
744 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
745 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
746 (w32_delayed_load): Move to w32.c.
747
748 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.

751 (w32_delayed_load): Move from image.c. When loading a library, record
752 its filename in the :loaded-from property of the library id.
753 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
754 Initialize and staticpro them.
755 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
756
757 * process.c: Include lisp.h before w32.h, not after.
758 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
759 instead of gnutls_record_check_pending.
760
761 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
762
763 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
764
765 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
766 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists

791
792 * callproc.c: Indentation fixup.
793
794 * sysdep.c (wait_for_termination_1): Make static.
795 (wait_for_termination, interruptible_wait_for_termination):
796 Move after wait_for_termination_1.
797
798 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
799
800 * sysdep.c (interruptible_wait_for_termination): New function
801 which is like wait_for_termination, but allows keyboard
802 interruptions.
803
804 * callproc.c (Fcall_process): Add (:file "file") as an option for
805 the STDOUT buffer.
806 (Fcall_process_region): Ditto.
807
808 2011-04-30 Eli Zaretskii <eliz@gnu.org>
809
810 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
811 rather than `XVECTOR (FOO)->size'.
812
813 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
814 inttypes.h, as a gnulib replacement is used if it not available in
815 system headers.
816
817 2011-04-21 Eli Zaretskii <eliz@gnu.org>
818
819 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

829 charbuf for the composition carryover bytes.
830
831 2011-04-21 Eli Zaretskii <eliz@gnu.org>
832
833 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
834 aborting when %lld or %lll format is passed.
835 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
836 %llo or %llx format is passed. (Bug#8545)
837
838 * window.c (window_scroll_line_based): Use a marker instead of
839 simple variables to record original value of point. (Bug#7952)
840
841 * doprnt.c (doprnt): Fix the case where a multibyte sequence
842 produced by %s or %c overflows available buffer space. (Bug#8545)
843
844 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
845
846 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

861 2011-04-28 Eli Zaretskii <eliz@gnu.org>
862
863 * doprnt.c (doprnt): Don't return value smaller than the buffer
864 size if the message was truncated. (Bug#8545).
865
866 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
867
868 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
869 (Fx_window_property): #if-0 the whole functions, not just the bodies.
870
871 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
872
873 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
874
875 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
876
877 * makefile.w32-in: Update dependencies.
878
879 2011-04-27 Eli Zaretskii <eliz@gnu.org>
880
881 Improve `doprnt' and its usage. (Bug#8545)
882 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
883 `format_end'. Remove support for %l as a conversion specifier.
884 Don't use xrealloc. Improve diagnostics when the %l size modifier
885 is used. Update the commentary.
886
887 * eval.c (verror): Simplify calculation of size_t.
888
889 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
890 messages.
891
892 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
893
894 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
895 change.
896
897 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
898
899 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
900 This makes this file independent of the recent pseudovector change.
901
902 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
903
904 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
905
906 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
907 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
908 Remove unused local.
909 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
910
911 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
912 GCC 4.6.0 optimizes based on type-based alias analysis.
913 For example, if b is of type struct buffer * and v of type struct
914 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
915 != &v->size, and therefore "v->size = 1; b->size = 2; return
916 v->size;" must therefore return 1. This assumption is incorrect
917 for Emacs, since it type-puns struct Lisp_Vector * with many other
918 types. To fix this problem, this patch adds a new type struct
919 vectorlike_header that documents the constraints on layout of vectors
920 and pseudovectors, and helps optimizing compilers not get fooled
921 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
922 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
923 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
924 the size member.
925 (XSETPVECTYPE): Rewrite in terms of new macro.
926 (XSETPVECTYPESIZE): New macro, specifying both type and size.
927 This is a bit clearer, and further avoids the possibility of
928 undesirable aliasing.
929 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
930 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
931 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
932 since Lisp_Subr is a special case (no "next" field).
933 (ASIZE): Now uses header.size rather than size.
934 All previous uses of XVECTOR (foo)->size replaced to use this macro,
935 to avoid the hassle of writing XVECTOR (foo)->header.size.
936 (struct vectorlike_header): New type.
937 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
938 object, to help avoid aliasing.
939 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
940 (SUBRP): Likewise, since Lisp_Subr is a special case.
941 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
942 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
943 (struct Lisp_Hash_Table): Combine first two members into a single
944 struct vectorlike_header member. All uses of "size" and "next" members
945 changed to be "header.size" and "header.next".
946 * buffer.h (struct buffer): Likewise.
947 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
948 * frame.h (struct frame): Likewise.
949 * process.h (struct Lisp_Process): Likewise.
950 * termhooks.h (struct terminal): Likewise.
951 * window.c (struct save_window_data, struct saved_window): Likewise.
952 * window.h (struct window): Likewise.
953 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
954 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
955 * buffer.c (init_buffer_once): Likewise.
956 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
957 special case.
958 * process.c (Fformat_network_address): Use local var for size,
959 for brevity.
960
961 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
962
963 Make the Lisp reader and string-to-float more consistent (Bug#8525)
964 * data.c (atof): Remove decl; no longer used or needed.
965 (digit_to_number): Move to lread.c.
966 (Fstring_to_number): Use new string_to_number function, to be
967 consistent with how the Lisp reader treats infinities and NaNs.
968 Do not assume that floating-point numbers represent EMACS_INT
969 without losing information; this is not true on most 64-bit hosts.
970 Avoid double-rounding errors, by insisting on integers when
971 parsing non-base-10 numbers, as the documentation specifies.
972 * lisp.h (string_to_number): New decl, replacing ...
973 (isfloat_string): Remove.
974 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
975 (read1): Do not accept +. and -. as integers; this
976 appears to have been a coding error. Similarly, do not accept
977 strings like +-1e0 as floating point numbers. Do not report
978 overflow for integer overflows unless the base is not 10 which
979 means we have no simple and reliable way to continue.
980 Break out the floating-point parsing into a new
981 function string_to_number, so that Fstring_to_number parses
982 floating point numbers consistently with the Lisp reader.
983 (digit_to_number): Move here from data.c. Make it static inline.
984 (E_CHAR, EXP_INT): Remove, replacing with ...
985 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
986 (string_to_number): New function, replacing isfloat_string.
987 This function checks for valid syntax and produces the resulting
988 Lisp float number too. Rework it so that string-to-number
989 no longer mishandles examples like "1.0e+". Use strtoumax,
990 so that overflow for non-base-10 numbers is reported only when
991 there's no portable and simple way to convert to floating point.
992
993 * textprop.c (set_text_properties_1): Rewrite for clarity,
994 and to avoid GCC warning about integer overflow.
995
996 * intervals.h (struct interval): Use EMACS_INT for members
997 where EMACS_UINT might cause problems. See
998 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
999 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
1000 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
1001 All uses changed.
1002 (offset_intervals): Tell GCC not to worry about length overflow
1003 when negating a negative length.
1004
1005 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
1006 (overrun_check_free): Likewise.
1007
1008 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
1009 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
1010 word size.
1011
1012 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
1013 (gnutls_make_error): Rename local to avoid shadowing.
1014 (gnutls_emacs_global_deinit): ifdef out; not used.
1015 (Fgnutls_boot): Use const for pointer to readonly storage.
1016 Comment out unused local. Fix pointer signedness problems.
1017
1018 * lread.c (openp): Don't stuff size_t into an 'int'.
1019 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
1020 about possible signed overflow.
1021
1022 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
1023 (GDK_KEY_g): Don't define if already defined.
1024 (xg_prepare_tooltip): Avoid pointer signedness problem.
1025 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
1026
1027 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
1028 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
1029
1030 * xfns.c (Fx_window_property): Simplify a bit,
1031 to make a bit faster and to avoid GCC 4.6.0 warning.
1032 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
1033
1034 * fns.c (internal_equal): Don't assume size_t fits in int.
1035
1036 * alloc.c (compact_small_strings): Tighten assertion a little.
1037
1038 Replace pEd with more-general pI, and fix some printf arg casts.
1039 * lisp.h (pI): New macro, generalizing old pEd macro to other
1040 conversion specifiers. For example, use "...%"pI"d..." rather
1041 than "...%"pEd"...".
1042 (pEd): Remove. All uses replaced with similar uses of pI.
1043 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
1044 * alloc.c (check_pure_size): Don't overflow by converting size to int.
1045 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
1046 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
1047 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
1048 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
1049 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
1050 64-bit hosts.
1051 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
1052 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
1053 * print.c (safe_debug_print, print_object): Likewise.
1054 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
1055 to int.
1056 Use pI instead of if-then-else-abort. Use %p to avoid casts,
1057 avoiding the 0 flag, which is not portable.
1058 * process.c (Fmake_network_process): Use pI to avoid cast.
1059 * region-cache.c (pp_cache): Likewise.
1060 * xdisp.c (decode_mode_spec): Likewise.
1061 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
1062 behavior on 64-bit hosts with printf arg.
1063 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
1064 (x_stop_queuing_selection_requests): Likewise.
1065 (x_get_window_property): Don't truncate byte count to an 'int'
1066 when tracing.
1067
1068 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
1069 here, since it parses constructs like leading '-' and spaces,
1070 which are not wanted; and it overflows with large numbers.
1071 Instead, simply match F[0-9]+, which is what is wanted anyway.
1072
1073 * alloc.c: Remove unportable assumptions about struct layout.
1074 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
1075 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
1076 (allocate_vectorlike, make_pure_vector): Use the new macros,
1077 plus offsetof, to remove unportable assumptions about struct layout.
1078 These assumptions hold on all porting targets that I know of, but
1079 they are not guaranteed, they're easy to remove, and removing them
1080 makes further changes easier.
1081
1082 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
1083 This doesn't fix a bug but makes the code clearer.
1084 (string_overrun_cookie): Now const. Use initializers that
1085 don't formally overflow signed char, to avoid warnings.
1086 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
1087 can cause Emacs to crash when string overrun checking is enabled.
1088 (allocate_buffer): Don't assume sizeof (struct buffer) is a
1089 multiple of sizeof (EMACS_INT); it need not be, if
1090 alignof(EMACS_INT) < sizeof (EMACS_INT).
1091 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
1092
1093 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
1094
1095 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.

1098
1099 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
1100 supposed to be handshaking. (Bug#8556)
1101 Reported by Paul Eggert <eggert@cs.ucla.edu>.
1102
1103 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
1104
1105 * lisp.h (Qdebug): List symbol.
1106 * eval.c (Qdebug): Restore global linkage.
1107 * keyboard.c (debug-on-event): New variable.
1108 (handle_user_signal): Break into debugger when debug-on-event
1109 matches the current signal symbol.
1110
1111 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
1112
1113 * alloc.c (check_sblock, check_string_bytes)
1114 (check_string_free_list): Convert to standard C.
1115
1116 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
1117
1118 * w32.c (emacs_gnutls_push): Fix typo.
1119
1120 2011-04-25 Eli Zaretskii <eliz@gnu.org>
1121
1122 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
1123 "cast to pointer from integer of different size".
1124
1125 Improve doprnt and its use in verror. (Bug#8545)
1126 * doprnt.c (doprnt): Document the set of format control sequences
1127 supported by the function. Use SAFE_ALLOCA instead of always
1128 using `alloca'.
1129
1130 * eval.c (verror): Don't limit the buffer size at size_max-1, that
1131 is one byte too soon. Don't use xrealloc; instead xfree and
1132 xmalloc anew.
1133
1134 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
1135
1136 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
1137 callbacks stage.
1138
1139 * gnutls.c: Renamed global_initialized to
1140 gnutls_global_initialized. Added internals for the
1141 :verify-hostname-error, :verify-error, and :verify-flags
1142 parameters of `gnutls-boot' and documented those parameters in the
1143 docstring. Start callback support.
1144 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
1145 unless a fatal error occured. Call gnutls_alert_send_appropriate
1146 on error. Return error code.
1147 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
1148 (emacs_gnutls_read): Likewise.
1149 (Fgnutls_boot): Return handshake error code.
1150 (emacs_gnutls_handle_error): New function.

1162 buffered some data internally if no FDs are set for TLS
1163 connections.

1170
1171 * xdisp.c (handle_single_display_spec): Rename the
1172 display_replaced_before_p argument into display_replaced_p, to
1173 make it consistent with the commentary. Fix typos in the
1174 commentary.
1175
1176 * textprop.c (syms_of_textprop): Remove dead code.
1177 (copy_text_properties): Delete obsolete commentary about an
1178 interface that was deleted long ago. Fix typos in the description
1179 of arguments.

1182 to changes in oldXMenu/XMenu.h from 2011-04-16.
1183 <menu_help_message, prev_menu_help_message>: Constify.
1184 (IT_menu_make_room): menu->help_text is now `const char **';
1185 adjust.
1186
1187 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
1188 to changes in oldXMenu/XMenu.h from 2011-04-16.

1191 * xfaces.c <Qunspecified>: Make extern again.
1192
1193 * syntax.c: Include sys/types.h before including regex.h, as
1194 required by Posix.
1195

1197
1198 * doprnt.c (doprnt): Improve commentary.
1199
1200 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
1201
1202 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
1203 them with etags.
1204
1205 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
1206 changes in globals.h immediately force recompilation.
1207 (TAGS): Depend on $(CURDIR)/m/intel386.h and
1208 $(CURDIR)/s/ms-w32.h.
1209 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
1210
1211 * character.c (Fchar_direction): Function deleted.
1212 (syms_of_character): Don't defsubr it.
1213 <char-direction-table>: Deleted.
1214
1215 2011-04-23 Eli Zaretskii <eliz@gnu.org>
1216
1217 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
1218 * doprnt.c: Include limits.h.
1219 (SIZE_MAX): New macro.
1220 (doprnt): Return a size_t value. 2nd arg is now size_t.
1221 Many local variables are now size_t instead of int or unsigned.
1222 Improve overflow protection. Support `l' modifier for integer
1223 conversions. Support %l conversion. Don't assume an EMACS_INT
1224 argument for integer conversions and for %c.
1225
1226 * lisp.h (doprnt): Restore prototype.
1227
1228 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
1229 $(SRC)/character.h.
1230
1231 * Makefile.in (base_obj): Add back doprnt.o.
1232
1233 * deps.mk (doprnt.o): Add back prerequisites.
1234 (callint.o): Depend on character.h.
1235
1236 * eval.c (internal_lisp_condition_case): Include the handler
1237 representation in the error message.
1238 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
1239 when breaking from the loop.
1240
1241 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
1242
1243 * callint.c (Fcall_interactively): When displaying error message
1244 about invalid control letter, pass the character's codepoint, not
1245 a pointer to its multibyte form. Improve display of the character
1246 in octal and display also its hex code.
1247
1248 * character.c (char_string): Use %x to display the (unsigned)
1249 codepoint of an invalid character, to avoid displaying a bogus
1250 negative value.
1251
1252 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
1253 `error', not SYMBOL_NAME itself.
1254
1255 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
1256 character arguments to `error'.
1257
1258 * charset.c (check_iso_charset_parameter): Fix incorrect argument
1259 to `error' in error message about FINAL_CHAR argument. Make sure
1260 FINAL_CHAR is a character, and use %c when it is passed as
1261 argument to `error'.
1262

1449
1450 * nsfont.m: Fixed bugs in ns_get_family and
1451 ns_descriptor_to_entity that were caused by using free to
1452 deallocate memory blocks that were allocated by xmalloc (via

1454 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
1455 --enable-checking=xmallocoverrun). xfree is now used to
1456 deallocate these memory blocks.

1473 (emacs_read, emacs_write): Use it.
1474 * process.c (send_process): Adjust to the new signatures of

1808
1809 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
1810 so that it's not optimized away.
1811 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
1812 * dispextern.h (bidi_dump_cached_states): Remove, since it's
1813 exported only to the debugger.
1814
1815 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
1816 * atimer.h (run_all_atimers): Remove; not exported.
1817
1818 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

1824 alloc.c: Import and export fewer symbols, and remove unused items.
1825 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
1826 is defined.

1842 * xdisp.c (message_enable_multibyte): Now static.
1843
1844 Declare Lisp_Object Q* variables to be 'static' if not exported.
1845 This makes it easier for human readers (and static analyzers)
1846 to see whether these variables are used from other modules.
1847 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
1848 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

1858 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
1859
1860 * lisp.h (DEFINE_FUNC): Make sname 'static'.
1861
1862 Make Emacs functions such as Fatom 'static' by default.
1863 This makes it easier for human readers (and static analyzers)
1864 to see whether these functions can be called from other modules.
1865 DEFUN now defines a static function. To make the function external
1866 so that it can be used in other C modules, use the new macro DEFUE.
1867 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
1868 (Finit_image_library):
1869 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
1870 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
1871 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
1872 Remove decls, since these functions are now static.
1873 (Funintern, Fget_internal_run_time): New decls, since these functions
1874 were already external.
1875
1876 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

1882 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
1883 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
1884 Mark functions with DEFUE instead of DEFUN,
1885 if they are used in other modules.
1886 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
1887 decls for now-static functions.
1888 * buffer.h (Fdelete_overlay): Remove decl.
1889 * callproc.c (Fgetenv_internal): Mark as internal.
1890 * composite.c (Fremove_list_of_text_properties): Remove decl.

1916

1919 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
1920
1921 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
1922 change. (Bug#8496)
1923
1924 2011-04-13 Eli Zaretskii <eliz@gnu.org>
1925
1926 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
1927 when at ZV. (Bug#8487)
1928
1929 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
1930
1931 * charset.c (Fclear_charset_maps): Use xfree instead of free.
1932 (Bug#8437)
1933 * keyboard.c (parse_tool_bar_item): Likewise.
1934 * sound.c (sound_cleanup, alsa_close): Likewise.

1938
1939 * alloc.c (overrun_check_malloc, overrun_check_realloc)
1940 (overrun_check_free): Protoize.
1941
1942 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
1943
1944 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
1945 since callers should never pass a negative size.
1946 Change the signature to match that of plain 'read' and 'write'; see
1947 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
1948 * lisp.h: Update prototypes of emacs_write and emacs_read.
1949
1950 2011-04-11 Eli Zaretskii <eliz@gnu.org>
1951
1952 * xdisp.c (redisplay_window): Don't try to determine the character
1953 position of the scroll margin if the window start point w->startp
1954 is outside the buffer's accessible region. (Bug#8468)
1955
1956 2011-04-10 Eli Zaretskii <eliz@gnu.org>
1957
1958 Fix write-region and its subroutines for buffers > 2GB.
1959 * fileio.c (a_write, e_write): Modify declaration of arguments and
1960 local variables to support buffers larger than 2GB.
1961 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
1962
1963 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
1964 argument, local variables, and return value.
1965
1966 * lisp.h: Update prototypes of emacs_write and emacs_read.
1967
1968 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
1969
1970 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
1971
1972 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
1973
1974 Fix more problems found by GCC 4.6.0's static checks.
1975
1976 * xdisp.c (vmessage): Use a better test for character truncation.
1977
1978 * charset.c (load_charset_map): <, not <=, for optimization,
1979 and to avoid potential problems with integer overflow.
1980 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
1981 * casetab.c (set_identity, shuffle): Likewise.
1982 * editfns.c (Fformat): Likewise.
1983 * syntax.c (skip_chars): Likewise.
1984
1985 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
1986 This also lets GCC 4.6.0 generate slightly better loop code.
1987
1988 * callint.c (Fcall_interactively): <, not <=, for optimization.
1989 (Fcall_interactively): Count the number of arguments produced,
1990 not the number of arguments given. This is simpler and lets GCC
1991 4.6.0 generate slightly better code.
1992
1993 * ftfont.c: Distingish more carefully between FcChar8 and char.
1994 The previous code passed unsigned char * to a functions like
1995 strlen and xstrcasecmp that expect char *, which does not
1996 conform to the C standard.
1997 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
1998 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
1999 char * when the C standard requires it.
2000
2001 * keyboard.c (read_char): Remove unused var.
2002
2003 * eval.c: Port to Windows vsnprintf (Bug#8435).
2004 Include <limits.h>.
2005 (SIZE_MAX): Define if the headers do not.
2006 (verror): Do not give up if vsnprintf returns a negative count.
2007 Instead, grow the buffer. This ports to Windows vsnprintf, which
2008 does not conform to C99. Problem reported by Eli Zaretskii.
2009 Also, simplify the allocation scheme, by avoiding the need for
2010 calling realloc, and removing the ALLOCATED variable.
2011
2012 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
2013
2014 Remove invocations of doprnt, as Emacs now uses vsnprintf.
2015 But keep the doprint source code for now, as we might revamp it
2016 and use it again (Bug#8435).
2017 * lisp.h (doprnt): Remove.
2018 * Makefile.in (base_obj): Remove doprnt.o.
2019 * deps.mk (doprnt.o): Remove.
2020
2021 error: Print 32- and 64-bit integers portably (Bug#8435).
2022 Without this change, on typical 64-bit hosts error ("...%d...", N)
2023 was used to print both 32- and 64-bit integers N, which relied on
2024 undefined behavior.
2025 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
2026 New macro.
2027 * lisp.h (error, verror): Mark as printf-like functions.
2028 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
2029 Report overflow in size calculations when allocating printf buffer.
2030 Do not truncate output string at its first null byte.
2031 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
2032 Truncate the output at a character boundary, since vsnprintf does not
2033 do that.
2034 * charset.c (check_iso_charset_parameter): Convert internal
2035 character to string before calling 'error', since %c now has the
2036 printf meaning.
2037 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
2038 overflow when computing char to be passed to 'error'. Do not
2039 pass Lisp_Object to 'error'; pass the integer instead.
2040 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
2041 formatted with plain %d.
2042
2043 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
2044
2045 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
2046
2047 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
2048
2049 * xterm.c (x_catch_errors): Remove duplicate declaration.
2050
2051 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
2052
2053 * xdisp.c, lisp.h (message_nolog): Remove; unused.
2054
2055 2011-04-10 Jim Meyering <meyering@redhat.com>
2056
2057 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
2058 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
2059 return ssize_t not "int", and use size_t as the buffer length.
2060 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
2061 * gnutls.h: Update declarations.
2062 * process.c (read_process_output): Use ssize_t, to match.
2063 (send_process): Likewise.
2064
2065 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
2066
2067 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
2068
2069 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
2070
2071 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
2072 Use unsigned char, to match FcChar8 type definition.
2073
2074 * xterm.c (handle_one_xevent):
2075 * xmenu.c (create_and_show_popup_menu):
2076 * xselect.c (x_decline_selection_request)
2077 (x_reply_selection_request): Avoid type-punned deref of X events.
2078
2079 2011-04-09 Eli Zaretskii <eliz@gnu.org>
2080
2081 Fix some uses of `int' instead of EMACS_INT.
2082 * search.c (string_match_1, fast_string_match)
2083 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
2084 (scan_buffer, find_next_newline_no_quit)
2085 (find_before_next_newline, search_command, Freplace_match)
2086 (Fmatch_data): Make some `int' variables be EMACS_INT.
2087
2088 * xdisp.c (display_count_lines): 3rd argument and return value now
2089 EMACS_INT. All callers changed.
2090 (pint2hrstr): Last argument is now EMACS_INT.

2125
2126 * process.c (Fformat_network_address): Doc fix.

2178 This avoids several warnings with gcc -Wstrict-overflow.
2179 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
2180 directly, rather than having caller test rule sign. This avoids
2181 some unnecessary tests.
2182 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
2183 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
2184 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
2185
2186 * xfont.c (xfont_text_extents): Remove var that was set but not used.
2187 (xfont_open): Avoid unnecessary tests.
2188
2189 * composite.c (composition_gstring_put_cache): Use unsigned integer.

2195 breaking out part of COMPOSITION_DECODE_RULE.
2196 (COMPOSITION_DECODE_RULE): Use it.
2197 * composite.c (get_composition_id): Remove unused local vars,
2198 by using the new macro.
2199
2200 * textprop.c (set_text_properties_1): Change while to do-while,
2201 since the condition is always true at first.
2202
2203 * intervals.c (graft_intervals_into_buffer): Mark var as used.
2204 (interval_deletion_adjustment): Return unsigned value.
2205 All uses changed.
2206
2207 * process.c (list_processes_1, create_pty, read_process_output):
2208 (exec_sentinel): Remove vars that were set but not used.

2218
2219 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
2220 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
2221 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
2222
2223 * print.c (print_error_message): Avoid int overflow.
2224
2225 * font.c (font_list_entities): Redo for clarity,
2226 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
2227
2228 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
2229 (font_score): Avoid potential overflow in diff calculation.
2230
2231 * fns.c (substring_both): Remove var that is set but not used.
2232 (sxhash): Redo loop for clarity and to avoid wraparound warning.
2233
2234 * eval.c (funcall_lambda): Rename local to avoid shadowing.
2235
2236 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
2237 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
2238 can always succeed if overflow has undefined behavior.
2239
2240 * search.c (boyer_moore, wordify): Remove vars set but not used.
2241 (wordify): Omit three unnecessary tests.
2242
2243 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

2259 but not used.
2260

2265
2266 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
2267
2268 * image.c (lookup_image): Remove var that is set but not used.
2269 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
2270
2271 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
2272 that are set but not used.
2273
2274 * xfns.c (make_invisible_cursor): Don't return garbage
2275 if XCreateBitmapFromData fails (Bug#8410).
2276
2277 * xselect.c (x_get_local_selection, x_handle_property_notify):
2278 Remove vars that are set but not used.
2279
2280 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
2281 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
2282
2283 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
2284 Remove var that is set but not used.
2285 (scroll_bar_windows_size): Now size_t, not int.
2286 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
2287 Check for overflow.
2288
2289 * xfaces.c (realize_named_face): Remove vars that are set but not used.
2290 (map_tty_color) [!defined MSDOS]: Likewise.
2291
2292 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
2293
2294 * coding.c: Remove vars that are set but not used.
2295 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
2296 All callers changed.
2297 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
2298 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
2299 (decode_coding_charset): Remove vars that are set but not used.
2300
2301 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
2302 that is set but not used.
2303
2304 * print.c (print_object): Remove var that is set but not used.
2305
2306 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
2307 The gnulib version avoids calling malloc in the usual case,
2308 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
2309 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
2310 * filelock.c (current_lock_owner): Likewise.
2311 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
2312 * sysdep.c: Include allocator.h, careadlinkat.h.
2313 (emacs_no_realloc_allocator): New static constant.
2314 (emacs_readlink): New function.
2315 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
2316 ../lib/careadlinkat.h.
2317
2318 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
2319
2320 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
2321 first non-nil return value).
2322
2323 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
2324
2325 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
2326 if not defined (Bug#8403).
2327
2328 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
2329
2330 * xdisp.c (display_count_lines): Remove parameter `start',
2331 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

2345
2346 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
2347
2348 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
2349
2350 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
2351
2352 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
2353 later (Bug#8403).
2354
2355 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
2356
2357 Add lexical binding.
2358
2359 * window.c (Ftemp_output_buffer_show): New fun.
2360 (Fsave_window_excursion):
2361 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
2362
2363 * lread.c (lisp_file_lexically_bound_p): New function.
2364 (Fload): Bind Qlexical_binding.
2365 (readevalloop): Remove `evalfun' arg.
2366 Bind Qinternal_interpreter_environment.
2367 (Feval_buffer): Bind Qlexical_binding.
2368 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
2369 Mark as dynamic.
2370 (syms_of_lread): Declare `lexical-binding'.
2371
2372 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
2373
2374 * keyboard.c (eval_dyn): New fun.
2375 (menu_item_eval_property): Use it.
2376
2377 * image.c (parse_image_spec): Use Ffunctionp.
2378
2379 * fns.c (concat, mapcar1): Accept byte-code-functions.
2380
2381 * eval.c (Fsetq): Handle lexical vars.
2382 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
2383 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
2384 (FletX, Flet): Obey lexical binding.
2385 (Fcommandp): Handle closures.
2386 (Feval): New `lexical' arg.
2387 (eval_sub): New function extracted from Feval. Use it almost
2388 everywhere where Feval was used. Look up vars in lexical env.
2389 Handle closures.
2390 (Ffunctionp): Move from subr.el.
2391 (Ffuncall): Handle closures.
2392 (apply_lambda): Remove `eval_flags'.
2393 (funcall_lambda): Handle closures and new byte-code-functions.
2394 (Fspecial_variable_p): New function.
2395 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
2396 but without exporting it to Lisp.
2397
2398 * doc.c (Fdocumentation, store_function_docstring):
2399 * data.c (Finteractive_form): Handle closures.
2400
2401 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
2402 interactive spec.
2403
2404 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
2405 New byte-codes.
2406 (exec_byte_code): New function extracted from Fbyte_code to handle new
2407 calling convention for byte-code-functions. Add new byte-codes.
2408
2409 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
2410
2411 * alloc.c (Fmake_symbol): Init new `declared_special' field.
2412
2413 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
2414
2415 * xdisp.c (redisplay_internal): Fix prototype.
2416
2417 2011-03-31 Eli Zaretskii <eliz@gnu.org>
2418
2419 * xdisp.c (SCROLL_LIMIT): New macro.
2420 (try_scrolling): Use it when setting scroll_limit.
2421 Limit scrolling to 100 screen lines.
2422 (redisplay_window): Even when falling back on "recentering",
2423 position point in the window according to scroll-conservatively,
2424 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
2425
2426 (try_scrolling): When point is above the window, allow searching
2427 as far as scroll_max, or one screenful, to compute vertical
2428 distance from PT to the scroll margin position. This prevents
2429 try_scrolling from unnecessarily failing when
2430 scroll-conservatively is set to a value slightly larger than the
2431 window height. Clean up the case of PT below the margin at bottom
2432 of window: scroll_max can no longer be INT_MAX. When aggressive
2433 scrolling is in use, don't let point enter the opposite scroll
2434 margin as result of the scroll.
2435 (syms_of_xdisp) <scroll-conservatively>: Document the
2436 threshold of 100 lines for never-recentering scrolling.
2437
2438 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
2439
2440 * dispextern.h (move_it_by_lines):
2441 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
2442 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
2443 (message_log_check_duplicate): Remove parameters `prev_bol' and
2444 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
2445 (redisplay_internal): Remove parameter `preserve_echo_area',
2446 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
2447
2448 * indent.c (Fvertical_motion):
2449 * window.c (window_scroll_pixel_based, Frecenter):
2450 Don't pass `need_y_p' to `move_it_by_lines'.
2451
2452 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
2453
2454 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
2455 steal a few bits to be more compact.
2456 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
2457 Remove unneeded casts.
2458
2459 * bytecode.c (Fbyte_code): CAR and CDR can GC.
2460
2461 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
2462
2463 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
2464 binding" message (bug#7967).
2465
2466 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
2467
2468 Fix more problems found by GCC 4.6.0's static checks.
2469
2470 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
2471 Remove unused local var.
2472
2473 * editfns.c (Fmessage_box): Remove unused local var.
2474
2475 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
2476 (note_mode_line_or_margin_highlight, note_mouse_highlight):
2477 Omit unused local vars.
2478 * window.c (shrink_windows): Omit unused local var.
2479 * menu.c (digest_single_submenu): Omit unused local var.
2480 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
2481 Omit unused local var.
2482
2483 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
2484 Don't assume string length fits in int.
2485 (keyremap_step, read_key_sequence): Use size_t for sizes.
2486 (read_key_sequence): Don't check last_real_key_start redundantly.
2487
2488 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
2489 instead of alloca (Bug#8344).
2490
2491 * eval.c (Fbacktrace): Don't assume nargs fits in int.
2492 (Fbacktrace_frame): Don't assume nframes fits in int.
2493
2494 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
2495
2496 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
2497 concerns.
2498
2499 * term.c (produce_glyphless_glyph): Remove unnecessary test.
2500
2501 * cm.c (calccost): Turn while-do into do-while, for clarity.
2502
2503 * keyboard.c (syms_of_keyboard): Use the same style as later
2504 in this function when indexing through an array. This also
2505 works around GCC bug 48267.
2506
2507 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
2508
2509 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
2510
2511 * chartab.c (sub_char_table_ref_and_range): Redo for slight
2512 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
2513
2514 * keyboard.c, keyboard.h (num_input_events): Now size_t.
2515 This avoids undefined behavior on integer overflow, and is a bit
2516 more convenient anyway since it is compared to a size_t variable.
2517
2518 Variadic C functions now count arguments with size_t, not int.
2519 This avoids an unnecessary limitation on 64-bit machines, which
2520 caused (substring ...) to crash on large vectors (Bug#8344).

2748 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
2749
2750 Fix more problems found by GCC 4.5.2's static checks.
2751
2752 * coding.c (encode_coding_raw_text): Avoid unnecessary test
2753 the first time through the loop, since we know p0 < p1 then.
2754 This also avoids a gcc -Wstrict-overflow warning.
2755
2756 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
2757 leading to a memory leak, possible in functions like
2758 load_charset_map_from_file that can allocate an unbounded number
2759 of objects (Bug#8318).
2760
2761 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
2762 that could (at least in theory) be that large.
2763
2764 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
2765 This is less likely to overflow, and avoids undefined behavior if
2766 overflow does occur. All callers changed. Use strtoul to scan
2767 for the unsigned long integer.
2768 (pint2hrstr): Simplify and tune code slightly.
2769 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

2781
2782 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
2783
2784 * process.c (Fmake_network_process): Use socklen_t, not int,
2785 where POSIX says socklen_t is required in portable programs.
2786 This fixes a porting bug on hosts like 64-bit HP-UX, where
2787 socklen_t is wider than int (Bug#8277).
2788 (Fmake_network_process, server_accept_connection):
2789 (wait_reading_process_output, read_process_output):
2790 Likewise.
2791
2792 * process.c: Rename or move locals to avoid shadowing.

2799 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
2800 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
2801
2802 Make tparam.h and terminfo.c consistent.
2803 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
2804 Include tparam.h instead, since it declares them.
2805 * cm.h (PC): Remove extern decl; tparam.h now does this.
2806 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
2807 * terminfo.c: Include tparam.h, to check interfaces.
2808 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
2809 (tparam): Adjust signature to match interface in tparam.h;
2810 this removes some undefined behavior. Check that outstring and len
2811 are zero, which they always are with Emacs.
2812 * tparam.h (PC, BC, UP): New extern decls.
2813
2814 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

2826
2827 * xml.c (make_dom): Now static.
2828
2829 * composite.c (composition_compute_stop_pos): Rename local to
2830 avoid shadowing.
2831 (composition_reseat_it): Remove unused locals.
2832 (find_automatic_composition, composition_adjust_point): Likewise.
2833 (composition_update_it): Mark var as initialized.
2834 (find_automatic_composition): Mark vars as initialized,
2835 with a FIXME (Bug#8290).
2836
2837 character.h: Rename locals to avoid shadowing.
2838 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
2839 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
2840 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
2841 (BUF_DEC_POS): Be more systematic about renaming local temporaries
2842 to avoid shadowing.
2843
2844 * textprop.c (property_change_between_p): Remove; unused.
2845
2846 * intervals.c (interval_start_pos): Now static.

2851 Rename locals to avoid shadowing.
2852
2853 * sound.c (wav_play, au_play, Fplay_sound_internal):
2854 Fix pointer signedness.
2855 (alsa_choose_format): Remove unused local var.
2856 (wav_play): Initialize a variable to 0, to prevent undefined
2857 behavior (Bug#8278).
2858
2859 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
2860
2861 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
2862
2863 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
2864 clobbering (Bug#8298).
2865 * sysdep.c (sys_subshell): Likewise.
2866 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
2867
2868 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
2869 This should get cleaned up, so that child_setup has the
2870 same signature on all platforms.
2871
2872 * callproc.c (call_process_cleanup): Now static.
2873 (relocate_fd): Rename locals to avoid shadowing.
2874
2875 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
2876
2877 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
2878 not to be necessary, and produces flickering.
2879
2880 2011-03-20 Glenn Morris <rgm@gnu.org>
2881
2882 * config.in: Remove file.
2883

2914 (sigchld_handler): Now static.
2915
2916 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
2917 That way, the code declares only the vars that it needs.
2918 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
2919 * s/cygwin.h (PTY_ITERATION): Likewise.
2920 * s/darwin.h (PTY_ITERATION): Likewise.

2922
2923 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
2924 * process.c (allocate_pty): Don't declare stb unless it's needed.

2999 Move decls here, to check interfaces.
3000 * process.c (get_operating_system_release): Move decl to lisp.h.
3001 * xrdb.c (get_system_name): Likewise.
3002 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
3003 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
3004 some of which prompt warnings from gcc -Wbad-function-cast.
3005 (Fformat_time_string, Fencode_time, Finsert_char):
3006 (Ftranslate_region_internal, Fformat):

3034 (Fmemory_limit): Cast sbrk's returned value to char *.
3035

3041 Use functions, not macros, for up- and down-casing (Bug#8254).
3042 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3043 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
3044 to use the following functions instead of these macros.
3045 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
3046 EMACS_INT, since callers assume the returned value fits in int.

3049 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

3055 (regex_compile, re_search_2, re_match_2_internal):
3056 Remove unused local vars.

3059 (regex_compile, re_match_2_internal): Mark locals as initialized.
3060 (RETALLOC_IF): Define only if needed.
3061 (WORDCHAR_P): Likewise. This one is never needed, but is used
3062 only in a comment talking about a compiler bug, so put inside
3063 the #if 0 of that comment.
3064 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
3065 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

3079
3080 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.

3083 Rename locals to avoid shadowing.
3084 (Fvertical_motion): Mark locals as initialized.
3085

3090
3091 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
3092 New macros, so that the caller can use some names other than
3093 gcpro1, gcpro2, etc.
3094 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
3095 of the new macros.
3096 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
3097 argument, for consistency with GCPRO2_VAR, etc: it is now the
3098 prefix of the variable, not the variable itself. All uses
3099 changed.

3101 Rename locals to avoid shadowing.
3102
3103 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
3104 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
3105 dired.c's scmp function, had undefined behavior.
3106 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3107 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
3108 * buffer.h: ... to here, because these macros use current_buffer,
3109 and the new implementation with inline functions needs to have
3110 current_buffer in scope now, rather than later when the macros
3111 are used.
3112 (downcase, upcase1): New static inline functions.
3113 (DOWNCASE, UPCASE1): Reimplement using these functions.
3114 This avoids undefined behavior in expressions like
3115 DOWNCASE (x) == DOWNCASE (y), which previously suffered
3116 from race conditions in accessing the global variables
3117 case_temp1 and case_temp2.
3118 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
3119 * lisp.h (case_temp1, case_temp2): Remove their decls.
3120 * character.h (ASCII_CHAR_P): Move from here ...
3121 * lisp.h: ... to here, so that the inline functions mentioned
3122 above can use them.
3123
3124 * dired.c (directory_files_internal_unwind): Now static.
3125
3126 * fileio.c (file_name_as_directory, directory_file_name):

3128 Now static.
3129 (file_name_as_directory): Use const pointers when appropriate.
3130 (Fexpand_file_name): Likewise. In particular, newdir might
3131 point at constant storage, so make it a const pointer.
3132 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
3133 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
3134 signedness issues.
3135 (Fset_file_times, Finsert_file_contents, auto_save_error):
3136 Rename locals to avoid shadowing.

3139 (Ftry_completion, Fall_completions): Rename or remove locals
3140 to avoid shadowing.
3141
3142 * marker.c (bytepos_to_charpos): Remove; unused.
3143
3144 * lisp.h (verify_bytepos, count_markers): New decls,
3145 so that gcc does not warn that these functions aren't declared.
3146
3147 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
3148 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
3149 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
3150 (copy_text): Remove unused local var.
3151
3152 * filelock.c (within_one_second): Now static.
3153 (lock_file_1): Rename local to avoid shadowing.
3154
3155 * buffer.c (fix_overlays_before): Mark locals as initialized.
3156 (fix_start_end_in_overlays): Likewise. This function should be
3157 simplified by using pointers-to-pointers, but that's a different
3158 matter.
3159 (switch_to_buffer_1): Now static.
3160 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
3161 (report_overlay_modification): Rename locals to avoid shadowing.
3162
3163 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
3164 Fix pointer signedness issue.
3165 (sys_subshell): Mark local as volatile if checking for lint,
3166 to suppress a gcc -Wclobbered warning that does not seem to be right.
3167 (MAXPATHLEN): Define only if needed.
3168
3169 * process.c (serial_open, serial_configure): Move decls from here ...
3170 * systty.h: ... to here, so that they can be checked.
3171
3172 * fns.c (get_random, seed_random): Move extern decls from here ...
3173 * lisp.h: ... to here, so that they can be checked.
3174
3175 * sysdep.c (reset_io): Now static.
3176 (wait_for_termination_signal): Remove; unused.
3177
3178 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
3179 (copy_keymap_item, append_key, push_text_char_description):
3180 Now static.
3181 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
3182 (DENSE_TABLE_SIZE): Remove; unused.
3183 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
3184 (describe_map_tree):
3185 Rename locals to avoid shadowing.
3186
3187 * keyboard.c: Declare functions static if they are not used elsewhere.
3188 (echo_char, echo_dash, cmd_error, top_level_2):
3189 (poll_for_input, handle_async_input): Now static.
3190 (read_char, kbd_buffer_get_event, make_lispy_position):
3191 (make_lispy_event, make_lispy_movement, apply_modifiers):
3192 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

3203
3204 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
3205 (DEFINE_DUMMY_FUNCTION): New macro.
3206 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
3207 Use it.
3208 (main): Add casts to avoid warnings
3209 if GCC considers string literals to be constants.
3210
3211 * lisp.h (fatal_error_signal): Add decl, since it's exported.
3212
3213 * dbusbind.c: Pointer signedness fixes.
3214 (xd_signature, xd_append_arg, xd_initialize):

3334 For example, without this patch (encode-time 0 0 0 1 1
3335 1152921504606846976) returns the obviously-bogus value (-948597
3336 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
3337 reports time overflow. See
3338 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
