 115
 116         * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
 117         function attribute, so we only use it if it exists in the

 139         Remove dummy definition, as this problem was obsolete long ago.
 140
 141         Assume strerror.
 142         * sysdep.c (strerror) [!HAVE_STRERROR && !WINDOWSNT]: Remove.
 143
 144 2012-07-11  Dmitry Antipov  <dmantipov@yandex.ru>
 145
 146         Avoid calls to strlen in font processing functions.
 147         * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
 148         (font_open_by_name): Change to use length argument.  Adjust
 149         users accordingly.

 169         * s/aix4-2.h (unix): Remove; no longer needed.
 170
 171         EMACS_TIME simplification (Bug#11875).
 172         This replaces macros (which typically do not work in GDB)
 173         with functions, typedefs and enums, making the code easier to debug.
 174         The functional style also makes code easier to read and maintain.
 175         * systime.h: Include <sys/time.h> on all hosts, not just if
 176         WINDOWSNT, since 'struct timeval' is needed in general.
 177         (EMACS_TIME): Now a typedef, not a macro.
 178         (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
 179         not macros.
 180         (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
 181         (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
 182         (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
 183         (EMACS_TIME_LE): Now functions, not macros.
 184         (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
 185         (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
 186         which are not functions.  All uses rewritten to use:
 187         (make_emacs_time): New function.
 188         (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
 189         (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
 190         not functions.  All uses rewritten to use the following, respectively:
 191         (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
 192         (add_emacs_time, sub_emacs_time): New functions.
 193         * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
 194         * fileio.c (Fcopy_file):
 195         * xterm.c (XTflash): Get the current time closer to when it's used.
 196         * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
 197
 198         * bytecode.c (targets): Suppress -Woverride-init warnings.
 199
 200         Simplify by avoiding confusing use of strncpy etc.
 201         * doc.c (Fsnarf_documentation):
 202         * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
 203         * frame.c (Fmake_terminal_frame):
 204         * gtkutil.c (get_utf8_string):
 205         * lread.c (openp):
 206         * nsmenu.m (ns_update_menubar):
 207         * regex.c (regerror):
 208         Prefer memcpy to strncpy and strncat when either will do.
 209         * fileio.c (Fsubstitute_in_file_name):
 210         * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
 211         (menu_separator_name_p):
 212         * nsmenu.m (ns_update_menubar):
 213         Prefer memcmp to strncmp when either will do.
 214         * nsterm.m: Include <ftoastr.h>.
 215         (ns_get_color):
 216         * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
 217         Prefer snprintf to strncpy.
 218         * nsterm.m (ns_term_init):
 219         * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
 220         * nsterm.m (ns_term_init):
 221         Avoid the need for strncpy, by using build_string or
 222         make_unibyte_string directly.  Use dtoastr, not snprintf.
 223         * process.c (Fmake_network_process): Diagnose service names that
 224         are too long, rather than silently truncating them or creating
 225         non-null-terminated names.
 226         (Fnetwork_interface_info): Likewise, for interface names.
 227         * sysdep.c (system_process_attributes) [GNU_LINUX]:
 228         Prefer sprintf to strncat.
 229         * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

 233
 234         * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:

 241         * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
 242         * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
 243         where argument type is known to be a Lisp_Cons.
 244
 245 2012-07-10  Tom Tromey  <tromey@redhat.com>
 246
 247         * bytecode.c (BYTE_CODE_THREADED): New macro.
 248         (BYTE_CODES): New macro.  Replaces all old byte-code defines.
 249         (enum byte_code_op): New type.
 250         (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

 256         * lisp.h (make_pure_string): Fix prototype.
 257         (build_pure_c_string): New function, defined as static inline.  This
 258         provides a better opportunity to optimize away calls to strlen when
 259         the function is called with compile-time constant argument.
 260         * alloc.c (make_pure_c_string): Fix comment.  Change to add nchars
 261         argument, adjust users accordingly.  Use build_pure_c_string where
 262         appropriate.
 263         * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
 264         * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
 265         * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
 266
 267 2012-07-10  Dmitry Antipov  <dmantipov@yandex.ru>
 268
 269         Avoid calls to strlen in miscellaneous functions.
 270         * buffer.c (init_buffer): Use precalculated len, adjust if needed.
 271         * font.c (Ffont_xlfd_name): Likewise.  Change to call make_string.
 272         * lread.c (openp): Likewise.
 273
 274 2012-07-10  Dmitry Antipov  <dmantipov@yandex.ru>
 275
 276         Avoid calls to strlen in path processing functions.
 277         * fileio.c (file_name_as_directory): Add comment.  Change to add
 278         srclen argument and return the length of result.  Adjust users
 279         accordingly.
 280         (directory_file_name): Fix comment.  Change to add srclen argument,
 281         swap 1st and 2nd arguments to obey the common convention.  Adjust
 282         users accordingly.
 283         * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
 284
 285 2012-07-10  Glenn Morris  <rgm@gnu.org>
 286
 287         * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
 288         Move PENDING_OUTPUT_COUNT definition to configure.

 291         * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
 292         * s/gnu.h (DATA_START): Move definitions to configure.
 293
 294         * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
 295         We include usg5-4-common.h, which defines them both.
 296
 297         * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
 298         O_RDONLY already includes it).
 299
 300         Stop ns builds setting the EMACSLOADPATH environment variable.
 301         * nsterm.m (ns_load_path): Rename from ns_init_paths.
 302         Now it does not set EMACSLOADPATH, just returns the load-path string.
 303         * nsterm.h: Update accordingly.
 304         * lread.c [HAVE_NS]: Include nsterm.h.

 307
 308 2012-07-09  Glenn Morris  <rgm@gnu.org>
 309
 310         * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
 311         since the included bsd-common.h does so.
 312
 313         Stop ns builds setting the EMACSPATH environment variable.
 314         * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
 315         (ns_init_paths): Do not set EMACSPATH.
 316         * nsterm.h (ns_exec_path): Add it.
 317         * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
 318         Use ns_exec_path.

 321
 322 2012-07-09  Paul Eggert  <eggert@cs.ucla.edu>
 323
 324         * process.c (wait_reading_process_output): 'waitchannels' was unset
 325         when read_kbd || !NILP (wait_for_cell); fix this.
 326
 327         Add GCC-style 'const' attribute to functions that can use it.
 328         * character.h (char_resolve_modifier_mask):
 329         * keyboard.h (make_ctrl_char):
 330         * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

 339         Add decls with ATTRIBUTE_CONST.
 340
 341         Minor improvements to make_formatted_string.
 342         * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
 343         where int is good enough, as vsprintf returns an int.
 344         * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
 345
 346 2012-07-09  Dmitry Antipov  <dmantipov@yandex.ru>
 347
 348         Use make_formatted_string to avoid double length calculation.
 349         * lisp.h (make_formatted_string): New prototype.
 350         * alloc.c (make_formatted_string): New function.
 351         * buffer.c (Fgenerate_new_buffer_name): Use it.
 352         * dbus.c (syms_of_dbusbind): Likewise.
 353         * editfns.c (Fcurrent_time_zone): Likewise.
 354         * filelock.c (get_boot_time): Likewise.

 363
 364 2012-07-09  Glenn Morris  <rgm@gnu.org>
 365
 366         Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
 367         * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
 368         (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
 369         * nsterm.h (ns_etc_directory): Add it.
 370         * callproc.c [HAVE_NS]: Include nsterm.h.

 372
 373 2012-07-09  Dmitry Antipov  <dmantipov@yandex.ru>
 374
 375         Move marker debugging code under MARKER_DEBUG.
 376         * marker.c (MARKER_DEBUG): Move marker debugging code under
 377         #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
 378         for bootstrap with --enable-checking (~3x slowdown reported
 379         by Juanma Barranquero <lekktu@gmail.com>).
 380         (verify_bytepos): Move under #ifdef MARKER_DEBUG.
 381
 382 2012-07-08  Paul Eggert  <eggert@cs.ucla.edu>
 383
 384         * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
 385         See <http://bugs.gnu.org/11825#29>.
 386
 387 2012-07-08  Eli Zaretskii  <eliz@gnu.org>
 388
 389         * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
 390         has no font, use the frame's font.  (Bug#11813)
 391         (display_line): Add commentary about displaying truncation glyphs
 392         on GUI frames.
 393         (produce_special_glyphs): Move here from term.c.
 394
 395         * term.c (produce_special_glyphs): Move to xdisp.c.
 396
 397         * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
 398         section.
 399
 400 2012-07-07  Andreas Schwab  <schwab@linux-m68k.org>
 401
 402         * xdisp.c (display_line): Avoid warning about implicit declaration
 403         of FRAME_FONT.
 404
 405         * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
 406
 407         * lisp.h: Remove empty conditional.
 408
 409 2012-07-07  Paul Eggert  <eggert@cs.ucla.edu>
 410
 411         * lread.c (load_path_check): Now static.
 412
 413         Fix some minor --with-ns problems found by static checking.
 414         * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
 415         (x_set_font) [!HAVE_X_WINDOWS]:
 416         * image.c (xpm_load_image) [HAVE_NS]:
 417         (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
 418         (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
 419         Remove unused local.
 420         (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
 421         (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
 422         * image.c (x_create_bitmap_from_file) [HAVE_NS]:
 423         (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
 424         * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
 425         * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
 426         Fix pointer signedness problem.
 427         * xfaces.c (FRAME_X_FONT_TABLE):
 428         * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
 429
 430 2012-07-07  Glenn Morris  <rgm@gnu.org>
 431
 432         * lread.c (load_path_check): New function, split from init_lread.
 433         (init_lread): Reorganize.  Motivation:
 434         If EMACSLOADPATH is set, check/warn about that rather than the
 435         defaults, which we are not going to use.  Hence we can remove
 436         the turn_off_warning and WINDOWSNT || HAVE_NS tests.
 437         Don't warn if site-lisp directories are missing.
 438         If not installed, start from a blank load-path, since
 439         PATH_LOADSEARCH refers to the eventual installation directories.
 440
 441 2012-07-07  Eli Zaretskii  <eliz@gnu.org>
 442
 443         Support truncation and continuation glyphs on GUI frames, when
 444         fringes are disabled.  (Bug#11832)
 445         * xdisp.c (init_iterator): Get dimensions of truncation and
 446         continuation glyphs even if on GUI frames.  Adjust
 447         it->last_visible_x on GUI frames when the left or right fringes,
 448         or both, are absent.
 449         (start_display, move_it_in_display_line_to): Handle the case of a
 450         GUI frame without a fringe to display continuation or truncation
 451         glyphs.
 452         (insert_left_trunc_glyphs): Support GUI frames: make sure
 453         truncation glyphs overwrite enough glyphs from the current line to
 454         have sufficient space in pixels.
 455         (display_line): Support truncation and continuation glyphs on GUI
 456         frames.  If some spare pixels are left on the line after inserting
 457         the truncation glyphs, fill that space with a stretch glyph of a
 458         suitably computed width.
 459
 460         * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
 461         produce_glyphs, to support GUI sessions.
 462
 463 2012-07-07  Paul Eggert  <eggert@cs.ucla.edu>
 464
 465         * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
 466
 467         * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
 468
 469         Do not require float-time's arg to fit in time_t (Bug#11825).
 470         This works better on hosts where time_t is unsigned, and where
 471         float-time is applied to the (negative) difference between two times.
 472         * editfns.c (decode_time_components): Last arg is now double *,
 473         not int *, and means to store all the result as a double, without
 474         worrying about whether the seconds part fits in time_t.
 475         All callers changed.
 476         (lisp_time_argument): Remove last int * arg, as it's no longer needed.
 477         All callers changed.
 478         (Ffloat_time): Do not fail merely because the specified time falls
 479         outside of time_t range.
 480
 481 2012-07-07  Glenn Morris  <rgm@gnu.org>
 482

 484         * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
 485         * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
 486
 487 2012-07-07  Juanma Barranquero  <lekktu@gmail.com>
 488
 489         * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
 490         Update dependencies.
 491
 492         * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
 493
 494 2012-07-06  Paul Eggert  <eggert@cs.ucla.edu>
 495
 496         Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
 497         * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
 498         * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
 499         * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
 500         * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
 501         * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
 502
 503         * xfont.c (compare_font_names): Redo to omit the need for casts.
 504
 505 2012-07-06  Andreas Schwab  <schwab@linux-m68k.org>
 506
 507         * xfns.c (Fx_change_window_property): Doc fix.
 508         * w32fns.c (Fx_change_window_property): Doc fix.
 509
 510         * w32fns.c (Fx_window_property): Accept the same arguments as the
 511         X Windows version.  Doc fix.
 512         * xfns.c (Fx_window_property): Doc fix.  (Bug#11870)

 514 2012-07-06  Juanma Barranquero  <lekktu@gmail.com>
 515             Eli Zaretskii  <eliz@gnu.org>
 516
 517         * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
 518         Windows-specific code from nt/config.nt moved here.
 519         Obsolete settings removed.
 520
 521 2012-07-06  Paul Eggert  <eggert@cs.ucla.edu>
 522
 523         * process.c: Avoid unnecessary calls to gettime.
 524         (wait_reading_process_output): Don't get the time of day
 525         when gobbling data immediately and not waiting, as there's no need
 526         for it in that case.  This removes a FIXME.
 527
 528 2012-07-06  Jan Djärv  <jan.h.d@swipnet.se>
 529
 530         * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
 531         is defined (Bug#11768).
 532
 533 2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>
 534
 535         Fix marker debugging code.
 536         * marker.c (byte_char_debug_check): Do not perform the check
 537         if buffer is not multibyte.
 538         (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
 539         Call byte_char_debug_check with correct arguments.
 540
 541 2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>
 542
 543         Compile marker debugging code only if ENABLE_CHECKING is defined.
 544         * marker.c (byte_char_debug_check, count_markers):
 545         Use only if ENABLE_CHECKING is defined.
 546         (byte_debug_flag): Remove.
 547         (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
 548         Always call byte_char_debug_check if ENABLE_CHECKING is defined.
 549
 550 2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>
 551
 552         Avoid code repetition in marker-related functions.
 553         * marker.c (attach_marker): New function.
 554         (Fset_marker, set_marker_restricted, set_marker_both)
 555         (set_marker_restricted_both): Use it.
 556         (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
 557         Consistently rename charno to charpos.
 558         (marker_position): Add eassert.
 559         (marker_byte_position): Convert to eassert.
 560
 561 2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>
 562
 563         Simplify list operations in unchain_overlay and unchain_marker.
 564         * buffer.c (unchain_overlay): Simplify.  Add comment.
 565         * marker.c (unchain_marker): Simplify.  Fix comments.
 566
 567 2012-07-06  Dmitry Antipov  <dmantipov@yandex.ru>

 581
 582         Do not use Fdelete_overlay in delete_all_overlays
 583         to avoid redundant calls to unchain_overlay.
 584         * buffer.c (drop_overlay): New function.
 585         (delete_all_overlays, Fdelete_overlay): Use it.
 586         * minibuf.c (get_minibuffer): Fix comment.
 587
 588 2012-07-06  Paul Eggert  <eggert@cs.ucla.edu>
 589
 590         Port to OpenBSD 5.1 amd64.
 591         * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
 592         This is needed for OpenBSD, and should be harmless on all BSD systems.
 593         Also, include <sys/sysctl.h>, as it should be available on all
 594         BSD_SYSTEM hosts given that we're already calling sysctl in that case.
 595         (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
 596         use p_pid member, not kp_proc.pid.
 597
 598 2012-07-06  Glenn Morris  <rgm@gnu.org>
 599
 600         * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
 601
 602 2012-07-05  Paul Eggert  <eggert@cs.ucla.edu>
 603
 604         More xmalloc and related cleanup.
 605         * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
 606         * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

 614         * xterm.c:
 615         Omit needless casts involving void * pointers and allocation.
 616         Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
 617         as the former is more robust if P's type is changed.
 618         Prefer xzalloc to xmalloc + memset 0.
 619         Simplify malloc-or-realloc to realloc.
 620         Don't worry about xmalloc returning a null pointer.
 621         Prefer xstrdup to xmalloc + strcpy.
 622         * editfns.c (Fmessage_box): Grow message_text by at least 80 when
 623         growing it.
 624         * keyboard.c (apply_modifiers_uncached): Prefer local array to
 625         alloca of a constant.
 626
 627 2012-07-05  Eli Zaretskii  <eliz@gnu.org>
 628
 629         * xdisp.c (display_line): Fix horizontal pixel coordinates when
 630         hscroll is larger than the line width.  Fixes long and futile
 631         looping inside extend_face_to_end_of_line (on a TTY) producing
 632         glyphs that are not needed and thrown away.
 633
 634 2012-07-05  Dmitry Antipov  <dmantipov@yandex.ru>

 642
 643 2012-07-05  Jan Djärv  <jan.h.d@swipnet.se>
 644
 645         * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
 646         not defined (Bug#11768).

 735
 736         * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
 737         This should be fixed in a better way; see Eli Zaretskii in
 738         <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
 739         (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
 740
 741         * fileio.c (time_error_value): Rename from special_mtime.
 742         The old name's problems were noted by Eli Zaretskii in
 743         <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
 744
 745         * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
 746         This variable's comment says Emacs needs at least one GDB-visible
 747         symbol of type enum pvec_type, to work around GDB problems.
 748         The symbol's value doesn't matter.
 749
 750         * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
 751         that causes compilation to fail on pre-C99 compilers.

 779         (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
 780         (sweep_vectors): Use it.  Use local var `total_bytes' instead of
 781         abusing vector->header.next.nbytes.
 782         (live_vector_p): Use PVEC_TYPE.
 783         (mark_object): Adapt code to extract pvectype.  Use switch.

 785 2012-07-04  Paul Eggert  <eggert@cs.ucla.edu>
 786

 789
 790 2012-07-04  Dmitry Antipov  <dmantipov@yandex.ru>
 791
 792         Fix compilation with --enable-gcc-warnings and -O1
 793         optimization level.
 794         * doprnt.c (doprnt): Change type of tem to int, initialize
 795         to avoid compiler warning.  Add eassert.

 801         Avoid weird behavior with large horizontal scrolls.
 802         Without this change, for example, large hscroll values would
 803         mess up Emacs's display on Fedora 15 x86, presumably due to
 804         overflows in int calculations in the display code.
 805         Also, if buffers had long lines, Emacs would freeze.
 806         * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
 807         (set_window_hscroll): New function, containing the old guts of
 808         Fset_window_hscroll.  Return the clipped value.
 809         (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
 810         This avoids the need to check against PTRDIFF_MAX.
 811
 812         * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.

 819
 820         * regex.c: Suppress GCC warning on RHEL 6.  (Bug#11207)
 821         Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
 822         since GCC 4.4.6 issues a bogus warning for them.
 823
 824         Fix bugs in file timestamp newness comparisons.
 825         * fileio.c (Ffile_newer_than_file_p):
 826         * lread.c (Fload): Use full timestamp resolution of files,
 827         not just the 1-second resolution, so that files that are only
 828         slightly newer still count as newer.
 829         * fileio.c (Ffile_newer_than_file_p): Don't assume file
 830         timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.

 832 2012-07-03  Paul Eggert  <eggert@cs.ucla.edu>

 922         Cleanup basic buffer management.
 923         * buffer.h (struct buffer): Change layout to use generic vector
 924         marking code.  Fix some comments.  Change type of 'clip_changed'
 925         to bitfield.  Remove unused #ifndef old.
 926         (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

 938         and related comments.

 940 2012-07-02  Paul Eggert  <eggert@cs.ucla.edu>
 941
 942         * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
 943         wrapper that is not needed because the wrapped code is a no-op (zero
 944         machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
 945         This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
 946
 947 2012-07-02  Dmitry Antipov  <dmantipov@yandex.ru>
 948

 950         (mark_object): Add comment.  Reorganize marking of vector-like
 951         objects.  Use CHECK_LIVE for all vector-like objects except buffers
 952         and subroutines when GC_CHECK_MARKED_OBJECTS is defined.  Avoid
 953         redundant calls to mark_vectorlike for bool vectors.

 961         This is rather than relying on --enable-locallisppath elements

 982         * msdos.c (gettime, settime): Define away the prototypes in dos.h,

 987         * font.c (font_style_to_value, font_style_symbolic)
 988         (font_prop_validate_style): Add type checks for values in
 989         font_style_table.
 990
 991         * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
 992         argument.
 993         * character.c, charset.c, menu.c, process.c, window.c: Adjust all
 994         uses.

 999
1000         * w32.c (getwd): Adjust commentary about startup_dir.
1001         (init_environment): Always call sys_access, even in non-MSVC
1002         builds.  Don't chdir to the directory of the Emacs executable.
1003         This undoes code from 1997 which was justified by the need to
1004         "avoid conflicts when removing and renaming directories".  But its
1005         downside was that every relative file name was being interpreted
1006         relative to the directory of the Emacs executable, which can never
1007         be TRT.  In particular, it broke sys_access when called with
1008         relative file names.
1009         (sys_access): Map GetLastError to errno.

1194         * lisp.h: Define build_string as static inline.  This provides

1202
1203         Use sprintf return value instead of invoking strlen on result.
1204         In the old days this wasn't portable, since some sprintf
1205         implementations returned char *.  But they died out years ago and
1206         Emacs already assumes sprintf returns int.
1207         Similarly for float_to_string.
1208         This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1209         * ccl.c (ccl_driver):

1216         Use sprintf or float_to_string result to avoid need to call strlen.
1217         * data.c (Fnumber_to_string):
1218         Use make_unibyte_string, since the string must be ASCII.
1219         * lisp.h, print.c (float_to_string): Now returns int length.
1220         * term.c (produce_glyphless_glyph):
1221         Use sprintf result rather than recomputing it.
1222
1223         Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1224         * Makefile.in (ALL_CFLAGS):

1248
1249         * gtkutil.c (get_utf8_string): Remove redundant assignment.
1250         sprintf already null-terminates its output.

1260
1261         * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1262         instead of truncating it to 63 (admittedly a generous limit).
1263
1264         * process.c: Fix spelling and caps in comments.

1348         All uses changed.
1349         (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
1350         not make_lisp_timeval, when the argument is of type EMACS_TIME.
1351
1352 2012-06-23  Eli Zaretskii  <eliz@gnu.org>
1353
1354         * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in

1392 2012-06-22  Paul Eggert  <eggert@cs.ucla.edu>
1393
1394         Support higher-resolution time stamps (Bug#9000).
1395         The time stamps are only nanosecond-resolution at the C level,
1396         since that's the best that any real-world system supports now.
1397         But they are picosecond-resolution at the Lisp level, as that's
1398         easy, and leaves room for future OS improvements.
1399
1400         * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1401         (LIBES): Use it.
1402
1403         * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1404         Don't get current time unless it's needed.
1405
1406         * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1407         now provides it if it's absent.
1408         (start_atimer): Port to higher-res time stamps.
1409         Check for time stamp overflow.  Don't get current time more
1410         often than is needed.
1411
1412         * buffer.h (struct buffer): Buffer modtime now has high resolution.
1413         Include systime.h, not time.h.
1414         (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1415
1416         * dired.c: Include stat-time.h.
1417         (Ffile-attributes): File times now have higher resolution.
1418
1419         * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1420         (struct image): Timestamp now has higher resolution.
1421
1422         * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1423         has at least microseconds now.  All uses removed.
1424         (update_frame, update_single_window, update_window, update_frame_1)
1425         (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1426
1427         * editfns.c (time_overflow): Now extern.
1428         (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1429         (float-time, Fformat_time_string, Fcurrent_time_string)
1430         (Fcurrent_time_zone): Accept and generate higher-resolution
1431         time stamps.
1432         (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1433         (decode_time_components, lisp_seconds_argument): New functions.
1434         (make_time): Now static.
1435         (lisp_time_argument): Now returns EMACS_TIME.  New arg ppsec.
1436         Report an error if the time is invalid, rather than having the caller
1437         do that.
1438
1439         * fileio.c: Include <stat-time.h>
1440         (Fcopy_file): Copy higher-resolution time stamps.
1441         Prefer to set the time stamp via a file descriptor if that works.

1443         (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1444         (Fvisited_file_modtime, Fset_visited_file_modtime):
1445         Support higher-resolution time stamps.
1446
1447         * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1448
1449         * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1450
1451         * image.c (prepare_image_for_display, clear_image_cache)
1452         (lookup_image): Port to higer-resolution time stamps.
1453
1454         * keyboard.c (start_polling, bind_polling_period):
1455         Check for time stamp overflow.
1456         (read_char, kbd_buffer_get_event, timer_start_idle)
1457         (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1458         (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1459         Port to higher-resolution time stamps.  Do not assume time_t is signed.
1460         (decode_timer): New function.  Timers are now vectors of length 9,
1461         not 8, to accommodate the picosecond component.
1462         (timer_check_2): Use it.
1463
1464         * nsterm.m (select_timeout, timeval_subtract): Remove.
1465         (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1466         as they're a bit more accurate and handle overflow better.
1467         (ns_select): Change prototype to be compatible with pselect.
1468         (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1469         * nsterm.h (ns_select): Adjust prototype.
1470
1471         * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1472         us-resolution time stamps.
1473         (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1474
1475         * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1476
1477         * lisp.h (time_overflow): New decl.
1478         (wait_reading_process_output): First arg is now intmax_t, not int,
1479         to accommodate larger waits.
1480
1481         * process.h (struct Lisp_Process.read_output_delay):
1482         Now counts nanoseconds, not microseconds.
1483         * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1484         EMACS_HAS_USECS.
1485         (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1486         (wait_reading_process_output):
1487         Port to ns-resolution time stamps.
1488         (Faccept_process_output, wait_reading_process_output):
1489         Check for time stamp overflow.  Do not assume time_t is signed.
1490         (select_wrapper): Remove; we now use pselect.
1491         (Fprocess_attributes): Now generates ns-resolution time stamps.
1492
1493         * sysdep.c: Include utimens.h.  Don't include utime.h
1494         or worry about struct utimbuf; gnulib does that for us now.
1495         (gettimeofday): Remove; gnulib provides a substitute.
1496         (make_timeval): New function.
1497         (set_file_times): Now sets ns-resolution time stamps.
1498         New arg FD; all uses changed.
1499         (time_from_jiffies, ltime_from_jiffies, get_up_time)
1500         (system_process_attributes):
1501         Now returns ns-resolution time stamp.  All uses changed.
1502         Check for time stamp overflow.
1503
1504         * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1505         provides a substitute now.
1506
1507         * systime.h: Include timespec.h rather than sys/time.h and time.h,
1508         since it guarantees struct timespec.
1509         (EMACS_TIME): Now struct timespec, so that we can support
1510         ns-resolution time stamps.
1511         (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1512         (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1513         (EMACS_USECS): Remove.
1514         (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1515         so multiply the arg by 1000 before storing it.
1516         (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1517         New macros.
1518         (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1519         Port to ns-resolution time stamps.
1520         (EMACS_TIME_NEG_P): Remove; replaced by....
1521         (EMACS_TIME_SIGN): New macro.
1522         (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
1523         (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
1524         (set_file_times, make_time, lisp_time_argument): Adjust signature.
1525         (make_timeval, make_lisp_time, decode_time_components): New decls.
1526         (EMACS_TIME_CMP): Remove; no longer used.  Plus, it was buggy, in
1527         that it mishandled time_t overflow.  You can't compare by subtracting!
1528         (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1529         (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1530
1531         * term.c: Include <sys/time.h>.

1534
1535         * undo.c (record_first_change): Support higher-resolution time stamps
1536         in the undo buffer.
1537         (Fprimitive_undo): Use them when restoring time stamps.
1538
1539         * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1540         (w32_get_internal_run_time):
1541         Port to higher-resolution Emacs time stamps.
1542         (ltime): Now accepts single 64-bit integer, as that's more convenient
1543         for callers.
1544
1545         * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1546
1547         * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1548         for compatibility with pselect.  Support ns-resolution time stamps.
1549
1550         * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1551
1552         * xselect.c (wait_for_property_change, x_get_foreign_selection):
1553         Check for time stamp overflow, and support ns-resolution time stamps.
1554
1555         * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1556         Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1557         (timeval_subtract): Remove; no longer needed.
1558         (XTflash, XTring_bell, x_wait_for_event):
1559         Port to ns-resolution time stamps.  Don't assume time_t is signed.

1566
1567         * alloc.c (NSTATICS): Enlarge to 0x650.  Otherwise, Emacs compiled
1568         with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1569         aborts in staticpro during startup.  (Without -DBYTE_CODE_METER,
1570         staticidx goes up to 1597 out of 1600 = 0x640.)
1571
1572 2012-06-20  Paul Eggert  <eggert@cs.ucla.edu>
1573
1574         * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1575         Otherwise, the umask might be mistakenly 0 while handling input signals.
1576

1578
1579         * minibuf.c (Fread_string): Bind minibuffer-completion-table.

1598         Callers changed.
1599         (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1600         since tty frames can be explicitly named.
1601         (prepare_menu_bars): Likewise.
1602
1603         * term.c (Ftty_top_frame): New function.
1604
1605 2012-06-18  Paul Eggert  <eggert@cs.ucla.edu>
1606
1607         Port byte-code-meter to modern targets.
1608         * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1609         !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG.  Problem with
1610         CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1611         <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1612         (METER_1, METER_2): Simplify.

1618 2012-06-18  Martin Rudalics  <rudalics@gmx.at>
1619
1620         * buffer.c (Fkill_buffer): Don't throw an error when the buffer
1621         gets killed during executing of this function (Bug#11665).
1622         Try to always return Qt when the buffer has been actually killed.
1623         (Vkill_buffer_query_functions): In doc-string say that functions
1624         run by this hook should not change the current buffer.
1625
1626 2012-06-18  Paul Eggert  <eggert@cs.ucla.edu>
1627
1628         Fix recently-introduced process.c problems found by static checking.
1629         * process.c (write_queue_push, write_queue_pop, send_process):
1630         Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.

1632         (send_process): Remove unused local.

1646 2012-06-17  Paul Eggert  <eggert@cs.ucla.edu>
1647
1648         * lisp.h (eassert): Assume C89 or later.
1649         This removes the need for CHECK.
1650         (CHECK): Remove.  Its comments about always evaluating its
1651         argument were confusing, as 'eassert' typically does not evaluate

1975         (all_vectors): Rename to `large_vectors'.
1976         (allocate_vector_from_block, init_vectors, allocate_vector_from_block)
1977         (sweep_vectors): New functions.
1978         (allocate_vectorlike): Return `zero_vector' as the only vector of
1979         0 items. Allocate new vector from block if vector size is less than
1980         or equal to VBLOCK_BYTES_MAX.
1981         (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
1982         (init_alloc_once): Add call to init_vectors.

1989
1990         * doprnt.c (doprnt): Truncate multibyte char correctly.
1991         Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
1992         would mishandle a string argument "Xc" if X was a multibyte
1993         character of length 2: it would truncate after X's first byte
1994         rather than including all of X.

2022
2023         * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
2024         (note_mode_line_or_margin_highlight): If there is no help echo,
2025         use mode-line-default-help-echo.  Handle the case where the mouse
2026         position is past the end of the mode line string.
2027
2028         * buffer.c (buffer_local_value_1): New function, split from
2029         Fbuffer_local_value; can return Qunbound.

2052

2057
2058         * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2059
2060 2012-06-01  Dmitry Antipov  <dmantipov@yandex.ru>
2061
2062         For a 'struct window', replace some Lisp_Object fields to
2063         bitfields where appropriate, remove unused fields.
2064         * window.h (struct window): Remove unused 'last_mark_x' and
2065         'last_mark_y' fields.  Rename 'mini_p' field to 'mini',
2066         change it's type from Lisp_Object to bitfield.
2067         Change type of 'force_start', 'optional_new_start',
2068         'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2069         fields from Lisp_Object to bitfield. Adjust users accordingly.

2072
2073         Pacify gcc -Wdouble-precision when using Xaw.

2075         [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2076         Use 'float' consistently, rather than 'float' in most places
2077         and 'double' in a couple of places.
2078
2079 2012-05-31  Eli Zaretskii  <eliz@gnu.org>
2080
2081         * xdisp.c (handle_stop): Detect whether we have overlay strings
2082         loaded by testing it->current.overlay_string_index to be
2083         non-negative, instead of checking whether n_overlay_strings is
2084         positive.  (Bug#11587)

2093
2094         * search.c (search_buffer): Remove calls to
2095         r_alloc_inhibit_buffer_relocation, as it is now called by
2096         maybe_unify_char, which was the cause of relocation of buffer text
2097         in bug#11519.
2098
2099 2012-05-31  Eli Zaretskii  <eliz@gnu.org>
2100
2101         * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2102         for the duration of call to load_charset, to avoid problems with
2103         callers of maybe_unify_char that access buffer text through C
2104         pointers.
2105
2106         * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2107         decrement the inhibition flag, instead of just setting or
2108         resetting it.

2112         Remove obsolete '#define static' cruft.
2113         * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2114         This #undef was "temporary" in 2000; it is no longer needed
2115         now that '#define static' has gone away.
2116         * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2117         (gray_bitmap_bits): Remove; no longer needed.
2118         All uses replaced with definiens.

2122
2123         Clean up __executable_start, monstartup when --enable-profiling.
2124         The following changes affect the code only when profiling.
2125         * dispnew.c (__executable_start): Rename from safe_bcopy.
2126         Define only on platforms that need it.
2127         * emacs.c: Include <sys/gmon.h> when profiling.
2128         (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2129         (__executable_start): Remove decl, since lisp.h does it now.
2130         (safe_bcopy): Remove decl; no longer has that name.
2131         (main): Coalesce #if into single bit of code, for simplicity.
2132         Cast pointers to uintptr_t, since standard libraries want integers
2133         and not pointers.
2134         * lisp.h (__executable_start): New decl.
2135
2136 2012-05-31  Glenn Morris  <rgm@gnu.org>

2160
2161         Do not create empty overlays with the evaporate property (Bug#9642).
2162         * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2163         Bug#9642, but explicitly check that the buffer the overlay would
2164         be moved to is live and rearrange lines to make sure that errors
2165         will not put the overlay in an inconsistent state.
2166         (Fdelete_overlay): Cosmetics.
2167
2168 2012-05-28  Eli Zaretskii  <eliz@gnu.org>
2169
2170         * w32term.c (my_bring_window_to_top): New function.
2171         (x_raise_frame): Use handle returned by DeferWindowPos, which
2172         could be different from the original one.
2173         Call my_bring_window_to_top instead of my_set_foreground_window.
2174         (Bug#11513)
2175
2176         * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2177         by calling BringWindowToTop.
2178
2179         * w32term.h (WM_EMACS_BRINGTOTOP): New message.

2183
2184         * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2185         This avoids undefined behavior that might cause the eassert
2186         to not catch an out-of-range value.
2187
2188 2012-05-28  Juanma Barranquero  <lekktu@gmail.com>
2189
2190         * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

2203
2204         * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2205         Only r_alloc_inhibit_buffer_relocation needed to be added;
2206         the others were already declared.
2207
2208         * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2209         before checking whether it's out of range.  Put the check inside
2210         eassert.  See
2211         <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

2216         commented out in the 2011-02-13 change (bug#11547).
2217
2218 2012-05-27  Eli Zaretskii  <eliz@gnu.org>
2219
2220         * lisp.h [REL_ALLOC]: Add prototypes for external functions
2221         defined on ralloc.c.
2222
2223         * buffer.c [REL_ALLOC]: Remove prototypes of
2224         r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2225         they are now on lisp.h.
2226
2227         * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2228
2229         * search.c (search_buffer): Use it to inhibit relocation of buffer
2230         text while re_search_2 is doing its job, because re_search_2 is
2231         passed C pointers to buffer text.  (Bug#11519)
2232
2233         * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2234         Update value to 24.
2235
2236         * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2237         state after an additional call to move_it_in_display_line_to, keep
2238         the values of it->max_ascent and it->max_descent found for the
2239         entire line.
2240         (pos_visible_p): Revert the comparison against bottom_y to what it
2241         was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

2245
2246         Fix coding-related core dumps with gcc -ftrapv.
2247         The code was computing A - B, where A and B are pointers, and B is
2248         random garbage.  This can lead to core dumps on platforms that
2249         have special pointer registers, and it also leads to core dumps on
2250         x86-64 when compiled with gcc -ftrapv.  The fix is to compute
2251         A - B only when B is initialized properly.
2252         * coding.c (coding_set_source, coding_set_destination): Return void.
2253         (coding_change_source, coding_change_destinations): New functions,
2254         with the old behaviors of coding_set_source and coding_set_destination.
2255         All callers that need an offset changed to use these new functions.

2262
2263         Extend mouse support on W32 text-mode console.
2264         * xdisp.c (draw_row_with_mouse_face):
2265         Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2266
2267         * w32console.c: Include window.h.
2268         (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):

2271
2272         * w32inevt.c: Include termchar.h and window.h.
2273         (do_mouse_event): Support mouse-autoselect-window.  When the mouse
2274         moves, call note_mouse_highlight.  If help_echo changed, call
2275         gen_help_event to produce help-echo message in the echo area.
2276         Call clear_mouse_face if mouse_face_hidden is set in the mouse
2277         highlight info.

2284 2012-05-26  Eli Zaretskii  <eliz@gnu.org>
2285
2286         * bidi.c (bidi_mirror_char): Revert last change: an int is

2289 2012-05-25  Paul Eggert  <eggert@cs.ucla.edu>
2290
2291         Fix integer width and related bugs (Bug#9874).

2301         Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2302         (allocate_pseudovector):
2303         Use int, not EMACS_INT, where int is wide enough.
2304         (inhibit_garbage_collection, Fgarbage_collect):
2305         Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2306         * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where

2343         for alloca overflow.  Don't compute the address of the object just
2344         before an array, as that's not portable.  Use EMACS_INT, not

2373         Always copy the vector, so that we can check its contents reliably
2374         now rather than having to recheck each instruction as it's being

2404         Don't rely on undefined behavior with signed left shift overflow.
2405         Don't assume unsigned int fits into fixnum, or that fixnum fits
2406         into unsigned int.  Don't require max_code to be a valid fixnum;
2407         that's not true for gb10830 4-byte on a 32-bit host.  Allow
2408         invalid_code to be a cons, for the same reason.  Require code_offset
2409         to be a character.  Avoid int overflow if max_char is close

2419         integer-overflow issues.
2420         (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2421         Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2422         where the argument is EMACS_INT, and this behavior is not intended.

2426         * cmds.c (move_point): New function, that does the gist of
2427         Fforward_char and Fbackward_char, but does so while checking

3075         Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3076         (selection_data_to_lisp_data): Use short, not EMACS_INT, where
3077         short is wide enough.
3078         (x_send_client_event): Don't assume fixnum fits in int.
3079         * xterm.c (x_x_to_emacs_modifiers):
3080         Don't assume EMACS_INT overflows nicely into int.
3081         (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
3082         may come from Lisp.
3083         (handle_one_xevent): NATNUMP can eval its arg twice.
3084         (x_connection_closed):
3085         Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3086         * xterm.h: Adjust decls to match defn changes elsewhere.
3087         (struct scroll_bar): Use struct vectorlike_header
3088         rather than rolling our own approximation.
3089         (SCROLL_BAR_VEC_SIZE): Remove; not used.
3090
3091 2012-05-25  Glenn Morris  <rgm@gnu.org>

3098         (read_pure): Remove var.

3102         (read_list): Simplify.
3103
3104         * fileio.c, character.h: Minor style tweaks.
3105
3106 2012-05-24  Dmitry Antipov  <dmantipov@yandex.ru>
3107
3108         * window.h (clip_changed): Remove useless declaration.

3115 2012-05-22  Paul Eggert  <eggert@cs.ucla.edu>

3118         This directory predates autoconf and is no longer needed nowadays.
3119         Move its few remaining bits of functionality to where they're needed.
3120         * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
3121         * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

3125         * lisp.h (USE_LSB_TAG):
3126         * mem-limits.h (EXCEEDS_LISP_PTR):
3127         Use VAL_MAX, not VALBITS, in #if.
3128         * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
3129         (EMACS_UINT): Define unconditionally now.
3130         (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3131         (BITS_PER_EMACS_INT): New constants, replacing
3132         what used to be in config.h, but not useful in #if.
3133         (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3134         define them any more.
3135         (VAL_MAX): New macro.
3136         (VALMASK): Use it.
3137         * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3138         BITS_PER_EMACS_INT, in #if.
3139         * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3140         (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3141         * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3142         * s/ms-w32.h (DATA_START):
3143         Move here from removed file m/intel386.h.
3144         * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3145         * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3146
3147 2012-05-21  Paul Eggert  <eggert@cs.ucla.edu>
3148
3149         Assume C89 or later.
3150         * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
3151         * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
3152         (xrealloc):
3153         * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
3154         * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):

3157         * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3158         * regex.h (_RE_ARGS): Remove.  All uses rewritten to use prototypes.
3159         * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3160         * xterm.c (input_signal_count): Assume volatile works.
3161
3162 2012-05-21  Ken Brown  <kbrown@cornell.edu>
3163
3164         * xgselect.c (xg_select): Fix first argument in call to 'select'
3165         (bug#11508).
3166
3167 2012-05-20  Ken Brown  <kbrown@cornell.edu>
3168
3169         * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3170         [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3171
3172 2012-05-19  Ken Brown  <kbrown@cornell.edu>
3173
3174         * xfns.c (x_in_use): Remove `static' qualifier.
3175         * xterm.h (x_in_use): Declare.
3176         * xgselect.c: Include xterm.h.
3177         (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3178         and `display_arg' (bug#9754).
3179
3180 2012-05-19  Paul Eggert  <eggert@cs.ucla.edu>
3181
3182         * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.

3189         Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3190
3191         * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3192         (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3193
3194         * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3195         reference to image_cache->refcount.
3196         (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3197
3198 2012-05-17  Juri Linkov  <juri@jurta.org>
3199
3200         * search.c (Fword_search_regexp, Fword_search_backward)
3201         (Fword_search_forward, Fword_search_backward_lax)
3202         (Fword_search_forward_lax): Move functions to isearch.el
3203         (bug#10145, bug#11381).
3204
3205 2012-05-16  Paul Eggert  <eggert@cs.ucla.edu>
3206
3207         * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3208
3209 2012-05-15  Stefan Monnier  <monnier@iro.umontreal.ca>
3210
3211         * lread.c (init_obarray): Declare Qt and Qnil as special.
3212
3213 2012-05-14  Glenn Morris  <rgm@gnu.org>
3214
3215         * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3216         Put "libexec" before "bin", for the sake of init_callproc_1.
3217
3218 2012-05-14  Paul Eggert  <eggert@cs.ucla.edu>
3219
3220         * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3221
3222         * unexaix.c: Port to more-recent AIX compilers.
3223         (report_error, report_error_1, make_hdr, copy_sym)
3224         (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3225         Make arguments const char *, not char *, to avoid violations of C
3226         standard and to fix some AIX warnings reported by Gilles Pion.
3227
3228 2012-05-14  Eli Zaretskii  <eliz@gnu.org>
3229
3230         * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3231         already have overlays loaded.
3232         (handle_single_display_spec): Before returning without displaying
3233         fringe bitmap, synchronize the bidi iterator with the main display
3234         iterator, by calling iterate_out_of_display_property.
3235         (iterate_out_of_display_property): Detect buffer iteration by
3236         testing that it->string is a Lisp string.
3237         (get_next_display_element): When the current object is exhausted,
3238         and there's something on it->stack, call set_iterator_to_next to
3239         proceed with what's on the stack, instead of returning zero.
3240         (set_iterator_to_next): If called at the end of a Lisp string,
3241         proceed to consider_string_end without incrementing string
3242         position.  Don't increment display vector index past the end of
3243         the display vector.  (Bug#11417)
3244         (pos_visible_p): Don't report a position visible when move_it_to
3245         stopped at the last line of window, which happens to be scanned
3246         backwards by the bidi iteration.  (Bug#11464)
3247
3248 2012-05-14  Eli Zaretskii  <eliz@gnu.org>
3249
3250         * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3251         and right-margin display specs even if the spec is invalid or we
3252         are on a TTY, and thus unable to display on the fringes.
3253         That's because the text with the property will not be displayed anyway,
3254         so we need to signal to the caller that this is a "replacing"
3255         display spec.  This fixes display when the spec is invalid or we
3256         are on a TTY.
3257
3258 2012-05-14  Paul Eggert  <eggert@cs.ucla.edu>
3259
3260         * unexaix.c (make_hdr): Fix typo in prototype.
3261         This bug broke the build on AIX.  Problem reported by Gilles Pion.
3262
3263 2012-05-14  Michael Albinus  <michael.albinus@gmx.de>
3264
3265         * keyboard.c (kbd_buffer_get_event): Read special events also in
3266         batch mode.  (Bug#11415)
3267
3268 2012-05-12  Glenn Morris  <rgm@gnu.org>
3269
3270         * ns.mk: Update for ns_appbindir no longer having trailing "/".
3271

3273
3274         * lisp.mk (lisp): Add newcomment.elc.
3275
3276 2012-05-12  Glenn Morris  <rgm@gnu.org>
3277
3278         * Makefile.in (MKDIR_P): New, set by configure.
3279         * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3280
3281 2012-05-11  Paul Eggert  <eggert@cs.ucla.edu>
3282
3283         Remove unused function hourglass_started.
3284         * dispextern.h (hourglass_started):
3285         * w32fns.c (hourglass_started):
3286         * xdisp.c (hourglass_started): Remove.
3287
3288 2012-05-10  Juanma Barranquero  <lekktu@gmail.com>
3289
3290         * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3291         Update dependencies.
3292
3293 2012-05-10  Paul Eggert  <eggert@cs.ucla.edu>
3294
3295         * xgselect.c (xg_select): Put maxfds+1 into a var.
3296         This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3297
3298         * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3299
3300 2012-05-10  Dave Abrahams  <dave@boostpro.com>
3301
3302         * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3303         (lock_file): If create_lockfiles is 0, do nothing.  (Bug#11227)
3304
3305 2012-05-09  Michael Albinus  <michael.albinus@gmx.de>
3306
3307         * dbusbind.c (xd_registered_buses): New internal Lisp object.
3308         Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3309         (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3310         Initialize xd_registered_buses.
3311
3312 2012-05-09  Paul Eggert  <eggert@cs.ucla.edu>
3313
3314         Untag more efficiently if USE_LSB_TAG.
3315         This is based on a proposal by YAMAMOTO Mitsuharu in
3316         <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3317         For an admittedly artificial (nth 8000 longlist) benchmark on
3318         Fedora 15 x86-64, this yields a 25% CPU speedup.  Also, it shrinks
3319         Emacs's overall text size by 1%.
3320         * lisp.h (XUNTAG): New macro.
3321         (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3322         (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3323         (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3324         * eval.c (Fautoload):
3325         * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3326         * frame.h (XFRAME): Use XUNTAG.
3327
3328         Port recent dbusbind.c changes to 32-bit --with-wide-int.
3329         * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3330         Remove unportable assumptions about print widths of types like
3331         dbus_uint32_t.
3332         (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3333         intptr_t when converting between pointer and integer, to avoid GCC
3334         warnings about wrong width.
3335
3336 2012-05-09  Eli Zaretskii  <eliz@gnu.org>
3337
3338         * w32proc.c (new_child): Force Windows to reserve only 64KB of
3339         stack for each reader_thread, instead of defaulting to 8MB
3340         determined by the linker.  This avoids failures in creating
3341         subprocesses on Windows 7, see the discussion in this thread:
3342         http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3343
3344 2012-05-07  Jérémy Compostella  <jeremy.compostella@gmail.com>
3345
3346         Fix up display of the *Minibuf-0* buffer in the mini window.
3347         * keyboard.c (read_char): Don't clear the echo area if there's no
3348         message to clear.
3349         * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3350         contents of *Minibuf-0*) if there's no message displayed in its stead.
3351
3352 2012-05-07  Michael Albinus  <michael.albinus@gmx.de>
3353
3354         * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3355         batch mode.
3356
3357 2012-05-06  Chong Yidong  <cyd@gnu.org>
3358
3359         * lisp.mk (lisp): Update.
3360
3361 2012-05-05  Jim Meyering  <meyering@redhat.com>
3362
3363         * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3364
3365 2012-05-04  Stefan Monnier  <monnier@iro.umontreal.ca>
3366
3367         * data.c (PUT_ERROR): New macro.
3368         (syms_of_data): Use it.  Add new error type `user-error'.
3369         * undo.c (user_error): New function.
3370         (Fprimitive_undo): Use it.
3371         * print.c (print_error_message): Adjust print style for `user-error'.
3372         * keyboard.c (user_error): New function.
3373         (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3374
3375 2012-05-03  Paul Eggert  <eggert@cs.ucla.edu>
3376
3377         Do not limit current-time-string to years 1000..9999.
3378         * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3379         (Fcurrent_time_string): Support any year that is supported by the
3380         underlying localtime representation.  Don't use asctime, as it
3381         has undefined behavior for years outside the range -999..9999.
3382
3383 2012-05-02  Paul Eggert  <eggert@cs.ucla.edu>
3384
3385         Fix race conditions involving setenv, gmtime, localtime, asctime.
3386         Without this fix, interrupts could mess up code that uses these
3387         nonreentrant functions, since setting TZ invalidates existing
3388         tm_zone or tzname values, and since most of these functions return
3389         pointers to static storage.
3390         * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3391         (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3392         Grow the critical sections to include not just invoking
3393         localtime/gmtime, but also accessing these functions' results
3394         including their tm_zone values if any, and any related TZ setting.
3395         (format_time_string): Last arg is now struct tm *, not struct tm **,
3396         so that the struct tm is saved in the critical section.
3397         All callers changed.  Simplify allocation of initial buffer, partly
3398         motivated by the fact that memory allocation needs to be outside
3399         the critical section.

3418         display string before the 'while' loop, don't walk back the glyphs
3419         from it3.glyph_row.  Solves assertion violation when the display
3420         string begins with a newline (egg.el).  (Bug#11367)

3431         and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3432         All were removed before 23.1.
3433
3434         * dispnew.c: Remove HAVE_LIBNCURSES test;
3435         it is always true on relevant platforms.
3436
3437         * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3438         Rename from LD_SWITCH_X_SITE_AUX_RPATH.

3450         Do not avoid creating empty evaporating overlays (Bug#9642).
3451         * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3452         That is, do not delete an evaporating overlay if it becomes
3453         empty after its bounds are adjusted to fit within its buffer.
3454         This fix caused other problems, and I'm reverting it until we get
3455         to the bottom of them.

3462
3463         * xdisp.c (pos_visible_p): If the window start position is beyond
3464         ZV, start the display from buffer beginning.  Prevents assertion
3465         violation in init_iterator when the minibuffer window is scrolled
3466         via the scroll bar.
3467

3489
3490         * w32menu.c: Include w32heap.h.
3491         (add_menu_item): If the call to AppendMenuW (via
3492         unicode_append_menu) fails, disable Unicode menus only if we are
3493         running on Windows 9X/Me.

3517
3518         Do not create empty overlays with the evaporate property (Bug#9642).
3519         * buffer.c (Fmove_overlay): Delete an evaporating overlay
3520         if it becomes empty after its bounds are adjusted to fit within
3521         its buffer.  Without this fix, in a nonempty buffer (let ((o
3522         (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3523         yields an empty overlay that has the evaporate property, which is
3524         not supposed to happen.
3525
3526         Fix minor GTK3 problems found by static checking.

3723         Fix minor alloc.c problems found by static checking.
3724         * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
3725         New extern decls, to avoid calling undeclared functions.
3726         (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3727         && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3728         GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

3737         (r_alloc_sbrk): Now static.
3738
3739         Improve ralloc.c interface checking.
3740         See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
3741         * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
3742         (r_alloc_free) [REL_ALLOC]: Move decls from here ...
3743         * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
3744         [REL_ALLOC]: ... to here, to check interface.
3745         * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
3746         Remove decls.  This fixes an "It stinks!".

3749
3750 2012-04-15  Andreas Schwab  <schwab@linux-m68k.org>
3751
3752         * lisp.h (struct Lisp_Symbol): Remove explicit padding.
3753         (struct Lisp_Misc_Any): Likewise.
3754         (struct Lisp_Free): Likewise.
3755         * alloc.c (union aligned_Lisp_Symbol): Define.
3756         (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
3757         aligned_Lisp_Symbol instead of struct Lisp_Symbol.
3758         (union aligned_Lisp_Misc): Define.
3759         (MARKER_BLOCK_SIZE, struct marker_block): Use union
3760         aligned_Lisp_Misc instead of union Lisp_Misc.

3766         * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
3767         * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
3768         * s/netbsd.h, s/sol2-6.h:
3769         Remove definition of GC_MARK_STACK, since the default now works.
3770         * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3771         Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3772         no longer the default.
3773         * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3774
3775 2012-04-14  Atsuo Ohki  <ohki@gssm.otsuka.tsukuba.ac.jp>  (tiny change)

3777         * lread.c (lisp_file_lexically_bound_p):
3778         Fix hang at ";-*-\n" (bug#11238).
3779
3780 2012-04-14  Eli Zaretskii  <eliz@gnu.org>
3781
3782         * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
3783         "unchanged" if its end.pos is beyond ZV.  (Bug#11199)
3784
3785 2012-04-14  Jan Djärv  <jan.h.d@swipnet.se>

3797
3798 2012-04-11  Daniel Colascione  <dancol@dancol.org>
3799
3800         * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3801         against is gone.  It's better to use vfork now so that when Cygwin
3802         gains a new, working vfork, we use it automatically (bug#10398).
3803
3804 2012-04-11  Stefan Monnier  <monnier@iro.umontreal.ca>

3828
3829         * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3830         not just in the obarray, before snarfing them.  (Bug#11036)
3831
3832         * Makefile.in ($(leimdir)/leim-list.el):
3833         Pass EMACS rather than BUILT_EMACS.

3842         Add convenience `GNUTLS_LOG2i' macro.
3843
3844         * gnutls.c (gnutls_log_function2i): Convenience log function.
3845         (emacs_gnutls_read): Use new log functions,
3846         `gnutls_handshakes_tried' process member, and
3847         `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
3848         attempts per process (connection).

3860
3861         * xdisp.c (set_cursor_from_row): If the display string appears in
3862         the buffer at position that is closer to point than the position
3863         after the display string, display the cursor on the first glyph of
3864         the display string.  Fixes cursor display when a 'display' text
3865         property immediately follows invisible text.  (Bug#11094)
3866
3867 2012-04-09  Paul Eggert  <eggert@cs.ucla.edu>
3868
3869         composite.c: use 'double' consistently
3870         * composite.c (get_composition_id): Use 'double' consistently
3871         instead of converting 'float' to 'double' and vice versa; this is
3872         easier to understand and avoids a GCC warning.
3873

3875
3876         * Makefile.in: Generate leim-list with bootstrap-emacs, in

3900         (mark_memory): Mark Lisp_Objects only if pointers might hide in
3901         objects, as mark_maybe_pointer will catch them otherwise.
3902         (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
3903         * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

3922         (init_libxml2_functions, libxml2_loaded_p): New functions.
3923         (parse_region): Call fn_xmlCheckVersion instead of using the macro
3924         LIBXML_TEST_VERSION.  Call libxml2 functions via the fn_* macros.
3925         (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
3926         Calls xmlCleanupParser only if libxml2 was loaded (or statically
3927         linked in).
3928         (Flibxml_parse_html_region, Flibxml_parse_xml_region):
3929         Call init_libxml2_functions before calling libxml2 functions.

3931
3932         * emacs.c: Don't include libxml/parser.h.

3935
3936         * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
3937
3938 2012-04-07  Eli Zaretskii  <eliz@gnu.org>
3939
3940         * indent.c (Fvertical_motion): If there is a display string at
3941         point, use it.vpos to compute how many lines to backtrack after
3942         move_it_to point.  (Bug#11133)
3943
3944 2012-04-06  Eli Zaretskii  <eliz@gnu.org>
3945

3947         * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3948         about subtle differences between FETCH_CHAR* and STRING_CHAR*
3949         macros related to unification of CJK characters.  For the details,

3968
3969         * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
3970         position we get to after a call to move_it_to fails the
3971         IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
3972         only if we wind up in a string from display property.  (Bug#11063)
3973
3974         * window.c (Fdelete_other_windows_internal): Invalidate the row
3975         and column information about mouse highlight, so that redisplay
3976         restores it after reallocating the glyph matrices.  (Bug#7464)
3977
3978         * xdisp.c (set_cursor_from_row): If `cursor' property on a display
3979         string comes from a `display' text property, use the buffer
3980         position of that property as if we actually saw that position in
3981         the row's glyphs.
3982         (move_it_by_lines): Remove the assertion that
3983         "it->current_x == 0 && it->hpos == 0" which can be legitimately
3984         violated when there's a before-string at the beginning of a line.
3985         (Bug#11063)
3986
3987 2012-03-30  Eli Zaretskii  <eliz@gnu.org>
3988
3989         * xdisp.c (append_space_for_newline): If the default face was
3990         remapped, use the remapped face for the appended newline.
3991         (extend_face_to_end_of_line): Use the remapped default face for
3992         extending the face to the end of the line.
3993         (display_line): Call extend_face_to_end_of_line when the default
3994         face was remapped.  (Bug#11068)

4030
4031         * s/ms-w32.h (tzname): Include time.h before redirecting to

4043
4044         * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4045         FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES.  Prevents crashes
4046         when fetching a multibyte character consumes more bytes than
4047         CHAR_BYTES returns, due to unification of CJK characters in
4048         string_char.  (Bug#11073)
4049
4050 2012-03-23  Troels Nielsen  <bn.troels@gmail.com>  (tiny change)
4051
4052         * process.c (wait_reading_process_output): Handle pty disconnect

4083
4084 2012-03-18  Eli Zaretskii  <eliz@gnu.org>
4085
4086         * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4087         that is not from display property, accept the row as a "cursor
4088         row" if one of the string's character has a non-nil `cursor'
4089         property.  Fixes cursor positioning when there are newlines in
4090         overlay strings, e.g. in icomplete.el.  (Bug#11035)

4132         * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4133         position past the first glyph_row that ends at ZV.  (Bug#10902)

4146         push_it before setting up the iterator for the first overlay
4147         string, even if we have an empty string loaded.
4148         (next_overlay_string): If there's an empty string on the iterator
4149         stack, pop the stack.  (Bug#10903)

4152
4153         Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4154         Suggested by Stefan Monnier in
4155         <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.

4157         (mark_memory): Also mark Lisp_Objects by fetching pointer words
4158         and widening them to Lisp_Objects.  This would work even if
4159         USE_LSB_TAG is defined and wide integers are used, which might
4160         happen in a future version of Emacs.
4161

4172
4173         * keyboard.c (process_special_events): Handle all X selection
4174         requests in kbd_buffer, not just the next one (Bug#8869).
4175
4176 2012-02-23  Chong Yidong  <cyd@gnu.org>
4177
4178         * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4179         call when setting menu-bar-lines and tool-bar-lines parameters.

4196         handler return value.
4197
4198 2012-02-20  Paul Eggert  <eggert@cs.ucla.edu>
4199
4200         * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4201         when computing $valmask.
4202
4203         Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4204         * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4205         (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4206         It's useless in that case, and it can cause problems on hosts
4207         that allocate halves of EMACS_INT values separately.
4208         Reported by Dan Horák.  Diagnosed by Andreas Schwab in
4209         <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4210         * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4211         UINTPTR_MAX >> VALBITS == 0.  This is required by the above change;
4212         it avoids undefined behavior on hosts where shifting right by more
4213         than the word width has undefined behavior.
4214
4215 2012-02-19  Chong Yidong  <cyd@gnu.org>

4238
4239         * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4240         marked as special.  Also, starting docstrings with * is obsolete.

4340         (char_width, c_string_width): Check for overflow when

4829
4830         * dispnew.c (adjust_glyph_matrix): Remove the assertion that
4831         verifies glyph row's hash code--we have just reallocated the

4864
4865         * dispnew.c (scrolling_window): Truncate overlaps in copy destination
4866         of scroll runs so as to avoid assigning disabled bogus rows and
4867         unnecessary graphics copy operations.
4868
4869 2011-11-27  Eli Zaretskii  <eliz@gnu.org>
4870

4908         after recentering, and scroll-conservatively is set to a large
4909         number, scroll window by a few more lines to make the cursor fully
4910         visible and out of scroll-margin.  (Bug#10105)
4911         (start_display): Don't move to the next line if the display should
4912         start at a newline that is part of a display vector or an overlay
4913         string.  (Bug#10119)

4939
4940         * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-

4992         Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
4993         Otherwise, valgrind does not work on some platforms.
4994         Problem reported by Andreas Schwab in
4995         <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
4996         * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
4997         is set, removing the need for VIRT_ADDRESS_VARIES.
4998         (PURE_P): Use a more-efficient implementation that needs just one
4999         comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5000         number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5001         to 4 (xorl, subq, cmpq, setbe).
5002         * alloc.c (pure): Always extern now, since that's the
5003         VIRT_ADDR_VARIES behavior.
5004         (PURE_POINTER_P): Use a single comparison, not two, for
5005         consistency with the new puresize.h.
5006         * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5007         * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
5008         Remove VIRT_ADDR_VARIES no longer needed.
5009
5010 2011-11-19  Eli Zaretskii  <eliz@gnu.org>
5011
5012         * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
5013         (erase_phys_cursor, update_window_cursor, show_mouse_face)
5014         (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5015         behave as if the cursor position were at the window margin.
5016
5017         * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5018         and the cursor position is out of bounds, behave as if the cursor
5019         position were at the window margin.  (Bug#10075)
5020
5021 2011-11-18  Chong Yidong  <cyd@gnu.org>
5022
5023         * window.c (Fwindow_combination_limit): Make first argument
5024         non-optional, since it is meaningless for live windows like the
5025         selected window.
5026
5027 2011-11-18  Dmitry Antipov  <dmantipov@yandex.ru>

5043
5044         * xdisp.c (row_hash): New function, body extracted from

5048
5049         * dispnew.c (verify_row_hash): Call row_hash for computing the
5050         hash code of a row, instead of duplicating code from xdisp.c.
5051
5052         * dispextern.h (row_hash): Add prototype.

5246         (offset_intervals): Rewrite using the old contents of
5247         static_offset_intervals.  The old version didn't conform to C99
5248         because an extern inline function contained a reference to an

5486         instead of calling the "wide" APIs directly.

5550         * bidi.c (bidi_line_init): Initialize the next_en_type member.
5551         (bidi_resolve_explicit_1): When next_en_pos is valid for the
5552         current character, check also for next_en_type being WEAK_EN.
5553         (bidi_resolve_weak): Don't enter the expensive loop if the current
5554         position is before next_en_pos.  Record the bidi type of the first
5555         non-ET, non-BN character we find, in addition to its position.

5560
5561         Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5562         * editfns.c: Rewrite current-time-zone so that it invokes
5563         the equivalent of (format-time-string "%Z") to get the time zone name.
5564         This fixes a bug when the time zone name contains characters that
5565         need converting from the system time locale to Emacs internal format.
5566         This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5567         that patch fixed format-time-string to do the conversion, but
5568         I forgot to fix current-time-zone.
5569         (format_time_string): New function, containing most of
5570         what Fformat_time_string used to contain.
5571         (Fformat_time_string): Rewrite in terms of format_time_string.
5572         This doesn't change this function's behavior.
5573         (current-time-zone): Rewrite to use format_time_string.
5574         This fixes the bug reported by Michael Schierl in
5575         <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5576         Jason Rumney's 2007-06-07 change worked around this bug, but
5577         didn't fix it.
5578         * systime.h (tzname, timezone): Remove no-longer-used declarations.
5579
5580 2011-10-19  Eli Zaretskii  <eliz@gnu.org>
5581
5582         * xdisp.c (start_display): If the character at POS is displayed
5583         via a display vector, reset IT->current.dpvec_index to zero.
5584         (try_window_reusing_current_matrix): If a line ends in a display
5585         vector or the next line starts in a display vector, continue
5586         redrawing the window even though the character position of
5587         start_row was reached.

5590 2011-10-18  Chong Yidong  <cyd@gnu.org>

5593         with nobreak-char-display too.
5594
5595 2011-10-18  Eli Zaretskii  <eliz@gnu.org>
5596
5597         Fix part 3 of bug#9771.
5598         * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5599         (bidi_resolve_neutral): Don't enter the expensive loop looking for
5600         non-neutral characters if the current character is a paragraph
5601         separator (a.k.a. Newline).  This avoids running the same
5602         expensive loop twice, once when we consume the preceding newline
5603         and the other time when the line actually needs to be displayed.
5604         Avoid the loop when we see neutrals on the base embedding level
5605         following a character whose directionality is the same as the
5606         paragraph's.  This avoids running the expensive loop when a line
5607         ends in a long sequence of neutrals, like control characters.
5608         Add assertion against STRONG_AL type.  Slightly rearrange code
5609         that determines the type of a neutral given the first non-neutral
5610         that follows it.
5611         (bidi_level_of_next_char): Set next_en_pos to zero when
5612         invalidating its info.
5613
5614 2011-10-17  Eli Zaretskii  <eliz@gnu.org>
5615
5616         * xdisp.c (push_display_prop): Determine whether to record string
5617         or buffer position by IT->string, not by IT->method.  Allow
5618         GET_FROM_DISPLAY_VECTOR as IT->method on entry.  (Bug#9771, part 4)
5619         (move_it_vertically_backward): Don't look for character position
5620         immediately after the newline when in a continuation line.
5621         (Bug#9771, part 1)
5622
5623 2011-10-15  Martin Rudalics  <rudalics@gmx.at>

5642         cursor motion with <left> and <right> arrow keys.
5643
5644         * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5645         some callers set that themselves.
5646
5647 2011-10-12  Eli Zaretskii  <eliz@gnu.org>

5675
5676         * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.

5710
5711         * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5712         or sizeof.  __alignof__ gives the wrong answer on Fedora x86-64
5713         with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5714         this makes Emacs dump core during garbage collection on rare
5715         occasions.  sizeof is obviously inferior to offsetof here, so
5716         stick with offsetof.
5717         (GC_POINTER_ALIGNMENT): New macro.
5718         (mark_memory): Omit 3rd (offset) arg; caller changed.
5719         Don't assume EMACS_INT alignment is the same as pointer alignment.

5744         * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5745         This fixes a Y2038 bug on 64-bit hosts.
5746         * buffer.c (reset_buffer):
5747         * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5748         (Fclear_buffer_auto_save_failure):
5749         Use 0, not -1, to represent an unset failure time, since time_t
5750         might not be signed.
5751
5752         Remove dependency on glibc malloc internals.
5753         * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5754         Move back here from lisp.h, but with their new implementations.
5755         (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5756         (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5757         * charset.c (charset_table_init): New static var.
5758         (syms_of_charset): Use it instead of xmalloc.  This removes a
5759         dependency on glibc malloc internals.  See Eli Zaretskii's comment in
5760         <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.

5774         Port --enable-checking=all to Fedora 14 x86-64.
5775         * charset.c (syms_of_charset): Also account for glibc malloc's
5776         internal overhead when calculating the initial malloc maximum.
5777
5778         Port --enable-checking=all to Fedora 14 x86.
5779         * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):

5781         (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5782         (overrun_check_realloc, overrun_check_free):
5783         Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5784         That way, xmalloc returns a properly-aligned pointer even if
5785         XMALLOC_OVERRUN_CHECK is defined.  The old debugging code happened
5786         to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5787         * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5788         into account when calculating the initial malloc maximum.
5789         * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5790         Move here from alloc.c, so that charset.c can use it too.
5791         Properly align; the old code wasn't right for common 32-bit hosts
5792         when configured with --enable-checking=all.
5793         (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)

5875         do not ignore write error for any output size
5876         The previous change was incomplete.
5877         While it makes emacs --batch detect the vast majority of stdout
5878         write failures, errors were still ignored whenever the output size is
5879         k * (BUFSIZ+1) - 4.  E.g., on a system with BUFSIZ of 4096,
5880           $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \

5905         (find_row_edges): If the row ends in a newline from a display

5907         Handle the case of a display string with multiple newlines.
5908         (Fcurrent_bidi_paragraph_direction): Fix search for previous

5925         positions even if no glyphs were produced (e.g., by a zero-width
5926         stretch).  Fixes bug#9530 on a TTY.  Under word-wrap, don't record
5927         buffer positions that will be removed from the glyph row because
5928         they don't fit.
5929         (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5930         column is beyond frame width: don't subtract 1 "pixel" when
5931         computing width of the stretch.
5932         (reseat_at_next_visible_line_start): Undo the change made on

6147         isnan: Fix porting problem to Solaris 10 with bundled gcc.
6148         Without this fix, the command to link temacs failed due to an
6149         undefined symbol __builtin_isnan.  This is because
6150         /usr/include/iso/math_c99.h #defines isnan(x) to
6151         __builtin_isnan(x), but the bundled gcc, which identifies itself
6152         as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6153         a __builtin_isnan.
6154         * floatfns.c (isnan): #undef, and then #define to a clone of

6165         * fileio.c: Fix bugs with large file offsets (Bug#9428).
6166         The previous code assumed that file offsets (off_t values) fit in
6167         EMACS_INT variables, which is not true on typical 32-bit hosts.
6168         The code messed up by falsely reporting buffer overflow in cases
6169         such as (insert-file-contents "big" nil 1 2) into an empty buffer
6170         when "big" contains more than 2**29 bytes, even though this
6171         inserts just one byte and does not overflow the buffer.
6172         (Finsert_file_contents): Store file offsets as off_t
6173         values, not as EMACS_INT values.  Check for overflow when
6174         converting between EMACS_INT and off_t.  When checking for
6175         buffer overflow or for overlap, take the offsets into account.
6176         Don't use EMACS_INT for small values where int suffices.
6177         When checking for overlap, fix a typo: ZV was used where
6178         ZV_BYTE was intended.
6179         (Fwrite_region): Don't assume off_t fits into 'long'.
6180         * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.

6194         (modify_event_symbol): Do not assume that the length of
6195         name_alist_or_stem is safe to alloca and fits in int.
6196         (Fexecute_extended_command): Likewise for function name and binding.
6197         (Frecursion_depth): Wrap around reliably on integer overflow.
6198         * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6199         since some callers pass EMACS_INT values.
6200         (Fsingle_key_description): Don't crash if symbol name contains more
6201         than MAX_ALLOCA bytes.
6202         * minibuf.c (minibuf_level): Now EMACS_INT, not int.

6204         * lisp.h (get_minibuffer, push_key_description): Reflect API changes.

6217         Don't mishandle offset == INT_MIN.
6218
6219         * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6220         when creating daemon; the previous buffer-overflow check was incorrect.
6221
6222         * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6223         which has the guts of the old verror function.
6224
6225         * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6226         use SAFE_ALLOCA instead.  Use esprintf to avoid int-overflow issues.
6227
6228         * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6229         (font_unparse_xlfd): Don't blindly alloca long strings.
6230         Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6231         fits in int, when using sprintf.  Use single snprintf to count
6232         length of string rather than counting it via multiple sprintfs;
6233         that's simpler and more reliable.
6234         (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6235         (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6236         sprintf, in case result does not fit in int.

6243         (x_report_frame_params): In X, window IDs are unsigned long,
6244         not signed long, so print them as unsigned.
6245         (validate_x_resource_name): Check for implausibly long names,
6246         and don't assume name length fits in 'int'.
6247         (x_get_resource_string): Don't blindly alloca invocation name;
6248         use SAFE_ALLOCA.  Use esprintf, not sprintf, in case result does
6249         not fit in int.
6250
6251         * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6252         (xg_check_special_colors, xg_set_geometry):
6253         Make sprintf buffers a bit bigger, to avoid potential buffer overrun.

6263
6264         * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6265         in case result does not fit in int.
6266
6267         * print.c (float_to_string): Detect width overflow more reliably.
6268         (print_object): Make sprintf buffer a bit bigger, to avoid potential
6269         buffer overrun.  Don't assume list length fits in 'int'.  Treat
6270         print length of 0 as 0, not as infinity; to be consistent with other
6271         uses of print length in this function.  Don't overflow print length
6272         index.  Don't assume hash table size fits in 'long', or that
6273         vectorlike size fits in 'unsigned long'.
6274

6295         Integer overflow fixes for scrolling, etc.
6296         Without these, Emacs silently mishandles large integers sometimes.
6297         For example, "C-u 4294967297 M-x recenter" was treated as if
6298         it were "C-u 1 M-x recenter" on a typical 64-bit host.

6304         Check that an Emacs fixnum is in range before assigning it to 'int'.
6305         (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6306         values converted from Emacs fixnums.
6307         (Frecenter): Don't wrap around a line count if it is out of 'int'
6308         range; instead, treat it as an extreme value.
6309         (Fset_window_configuration, compare_window_configurations):
6310         Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6311
6312         * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6313         that can exceed INT_MAX.  Check that EMACS_INT value is in range
6314         before assigning it to the (possibly-narrower) index.
6315         (match_limit): Don't assume that a fixnum can fit in 'int'.
6316
6317         * print.c (print_object): Use ptrdiff_t, not int, for index that can
6318         exceed INT_MAX.
6319
6320         * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6321         (Fvertical_motion): Don't wrap around LINES values that don't fit
6322         in 'int'.  Instead, treat them as extreme values.  This is good
6323         enough for windows, which can't have more than INT_MAX lines anyway.

6388
6389         Integer and memory overflow issues (Bug#9196).
6390
6391         * doc.c (get_doc_string): Rework so that
6392         get_doc_string_buffer_size is the actual buffer size, rather than
6393         being 1 less than the actual buffer size; this makes xpalloc more
6394         convenient.
6395
6396         * image.c (x_allocate_bitmap_record, cache_image):
6397         * xselect.c (Fx_register_dnd_atom):
6398         Simplify previous changes by using xpalloc.
6399
6400         * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6401         since either will do and ptrdiff_t is convenient with xpalloc.
6402
6403         * charset.c (charset_table_size)
6404         (struct charset_sort_data.priority): Now ptrdiff_t.
6405         (charset_compare): Don't overflow if priorities differ greatly.
6406         (Fsort_charsets): Don't assume list length fits in int.
6407         Check for size-calculation overflow when allocating sort data.
6408         (syms_of_charset): Allocate an initial charset table that is
6409         just under 64 KiB, to avoid problems with glibc malloc and mmap.
6410
6411         * cmds.c (internal_self_insert): Check for size-calculation overflow.
6412
6413         * composite.h (struct composition.glyph_len): Now int, not unsigned.
6414         The actual value is always <= INT_MAX, and leaving it unsigned made
6415         overflow checking harder.
6416
6417         * dispextern.h (struct glyph_matrix.rows_allocated)
6418         (struct face_cache.size): Now ptrdiff_t, for convenience in use
6419         with xpalloc.  The values are still always <= INT_MAX.
6420
6421         * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6422
6423         * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6424         (SAFE_NALLOCA): New macro.
6425
6426         * region-cache.c (struct boundary.pos, find_cache_boundary)
6427         (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6428         (set_cache_region, invalidate_region_cache)
6429         (revalidate_region_cache, know_region_cache, region_cache_forward)
6430         (region_cache_backward, pp_cache):
6431         Use ptrdiff_t, not EMACS_INT, since either will do.  This is needed
6432         so that ptrdiff_t * can be passed to xpalloc.
6433         (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6434         beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6435         (pp_cache): Don't assume cache_len fits in int.
6436         * region-cache.h: Adjust extern decls to match.
6437
6438         * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6439         EMACS_INT, since either will do, for xpalloc.
6440
6441         * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6442         (xnmalloc, xnrealloc, xpalloc): New functions.
6443
6444         * bidi.c (bidi_shelve_header_size): New constant.
6445         (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6446         (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6447
6448         * bidi.c (bidi_cache_shrink):
6449         * buffer.c (overlays_at, overlays_in, record_overlay_string)
6450         (overlay_strings):
6451         Don't update size of array until after memory allocation succeeds,
6452         because xmalloc/xrealloc may not return.
6453         (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6454         now that we have proper integer overflow checking.
6455         (record_overlay_string, overlay_strings): Catch overflows when
6456         calculating size of overlay_str_buf.
6457
6458         * callproc.c (Fcall_process): Check for size overflow when
6459         calculating size of args2.
6460         (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6461         Normally we prefer signed values, but sticking with ptrdiff_t would
6462         require adding more-complicated checks.
6463
6464         * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6465         Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6466         Redo buffer-overflow calculations to avoid integer overflow.
6467         Add a FIXME comment where memory seems to be over-allocated.
6468
6469         * character.c (Fstring): Check for size-calculation overflow.
6470
6471         * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6472         unnecessary integer overflow.  Check for size overflow.
6473         (encode_coding_object): Don't update size until xmalloc succeeds.
6474
6475         * composite.c (get_composition_id): Check for overflow in glyph
6476         length calculations.
6477
6478         Integer and memory overflow fixes for display code.
6479         * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6480         * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6481         (scrolling_window): Check for overflow in size calculations.
6482         (line_draw_cost, realloc_glyph_pool, add_row_entry):
6483         Don't assume glyph table len fits in int.
6484         (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
6485         (row_table_size): Now ptrdiff_t, not int.
6486         (scrolling_window): Avoid overflow in size calculations.
6487         Don't update size until allocation succeeds.
6488         * fns.c (concat): Check for overflow in size calculations.
6489         (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
6490         * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6491         (NEXT_ALMOST_PRIME_LIMIT): New constant.
6492
6493         * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
6494         (get_doc_string): Check for size calculation overflow.
6495         Don't update size until allocation succeeds.
6496         (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6497         EMACS_INT, where ptrdiff_t will do.
6498         (Fsubstitute_command_keys): Check for string overflow.
6499
6500         * editfns.c (set_time_zone_rule): Don't assume environment length
6501         fits in int.
6502         (message_length): Now ptrdiff_t, not int.
6503         (Fmessage_box): Don't update size until allocation succeeds.
6504         Don't assume message length fits in int.
6505         (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6506
6507         * emacs.c (main): Do not reallocate argv, since there is a null at
6508         the end that can be overwritten, and this way there's no need to
6509         worry about size-calculation overflow.
6510         (sort_args): Check for size-calculation overflow.
6511
6512         * eval.c (init_eval_once, grow_specpdl): Don't update size until
6513         alloc succeeds.
6514         (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
6515
6516         * frame.c (set_menu_bar_lines, x_set_frame_parameters)
6517         (x_set_scroll_bar_width, x_figure_window_size):
6518         Check for integer overflow.
6519         (x_set_alpha): Do not assume XINT fits in int.
6520
6521         * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6522         This is for the members text_lines, text_cols, total_lines, total_cols,
6523         where the system imposes an 'int' limit.
6524
6525         * fringe.c (Fdefine_fringe_bitmap):
6526         Don't update size until alloc works.
6527

6529         (ftfont_shape_by_flt): Check for integer overflow in size calculations.
6530
6531         * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
6532         Check for size-calculation overflow.
6533         (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6534         do, as we prefer signed integers.
6535         (id_to_widget.max_size, id_to_widget.used)
6536         (xg_store_widget_in_map, xg_remove_widget_from_map)
6537         (xg_get_widget_from_map, xg_get_scroll_id_for_window)
6538         (xg_remove_scroll_bar, xg_update_scrollbar_pos):
6539         Use and return ptrdiff_t, not int.
6540         (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
6541         * gtkutil.h: Change prototypes to match the above.
6542
6543         * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
6544         are duplicate now that they've been promoted to lisp.h.
6545         (x_allocate_bitmap_record, x_alloc_image_color)
6546         (make_image_cache, cache_image, xpm_load):

6548         (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
6549         (x_detect_edges):
6550         Check for size calculation overflow.
6551         (ct_colors_allocated_max): New constant.
6552         (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
6553         overflow.
6554
6555         * keyboard.c (read_char, menu_bar_items, tool_bar_items)
6556         (read_char_x_menu_prompt, read_char_minibuf_menu_width)
6557         (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
6558         Use ptrdiff_t, not int, to count maps.
6559         (read_char_minibuf_menu_prompt): Check for overflow in size
6560         calculations.  Don't update size until allocation succeeds.
6561         Redo calculations to avoid overflow.
6562         * keyboard.h: Change prototypes to match the above.
6563
6564         * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
6565         to count maps.
6566         (current_minor_maps): Check for size calculation overflow.
6567         * keymap.h: Change prototypes to match the above.
6568
6569         * lread.c (read1, init_obarray): Don't update size until alloc done.
6570
6571         * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
6572         (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
6573
6574         * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
6575         Now ptrdiff_t, not int.

6580         in size calculation.
6581
6582         * region-cache.c (move_cache_gap): Check for size calculation overflow.
6583
6584         * scroll.c (do_line_insertion_deletion_costs): Check for size calc
6585         overflow.  Don't bother calling xmalloc when xrealloc will do.
6586
6587         * search.c (Freplace_match): Check for size calculation overflow.
6588         (Fset_match_data): Don't assume list lengths fit in 'int'.
6589
6590         * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
6591         for command line length.  Do not attempt to address one before the
6592         beginning of an array, as that's not portable.
6593
6594         * term.c (max_frame_lines): Remove; unused.
6595         (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
6596         not int.
6597         (encode_terminal_code, calculate_costs): Check for size
6598         calculation overflow.
6599         (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
6600         table lengths and related sizes.  Don't update size until alloc
6601         done.  Redo calculations to avoid overflow.
6602         (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
6603
6604         * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
6605         subtracting pointers.
6606         (gobble_line): Check for overflow more carefully.  Don't update size
6607         until alloc done.
6608
6609         * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

6612         Check for size calculation overflow.
6613         (main) [DEBUG]: Fix typo in invoking tparam1.
6614
6615         * xdisp.c (store_mode_line_noprop_char, x_consider_frame_title):
6616         Use ptrdiff_t, not int, for sizes.
6617         (store_mode_line_noprop_char): Don't update size until alloc done.
6618
6619         * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
6620         Use ptrdiff_t, not int, for sizes.
6621         (Finternal_make_lisp_face, cache_face):
6622         Check for size calculation overflow.
6623         (cache_face): Treat size calculation overflows as if they were
6624         memory exhaustion (the usual treatment), rather than aborting.
6625
6626         * xfns.c (x_encode_text, x_set_name_internal)
6627         (Fx_change_window_property): Use ptrdiff_t, not int, to count
6628         sizes, since they can exceed INT_MAX in size.  Check for size
6629         calculation overflow.
6630
6631         * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
6632         (xg_select): Check for size calculation overflow.
6633         Don't update size until alloc done.
6634
6635         * xrdb.c (get_environ_db): Don't assume path length fits in int,
6636         as sprintf is limited to int lengths.
6637
6638         * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
6639         (X_LONG_MIN): New macros.
6640         Use them to make the following changes clearer.
6641         (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6642         This change doesn't affect the value now, but it may help remind
6643         future maintainers not to raise the value too much later.
6644         (SELECTION_QUANTUM): Remove, replacing with ...
6645         (selection_quantum): ... new function, which avoids overflow.
6646         All uses changed.
6647         (struct selection_data.size): Now ptrdiff_t, not int, to avoid
6648         assumption that selection length fits in 'int'.
6649         (x_reply_selection_request, x_handle_selection_request)
6650         (x_get_window_property, receive_incremental_selection)
6651         (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
6652         (lisp_data_to_selection_data, clean_local_selection_data):
6653         Use ptrdiff_t, not int, to record length of selection.
6654         (x_reply_selection_request, x_get_window_property)
6655         (receive_incremental_selection, x_property_data_to_lisp):
6656         Redo calculations to avoid overflow.
6657         (x_reply_selection_request): When sending hint, ceiling it at
6658         X_LONG_MAX rather than relying on wraparound overflow to send
6659         something.
6660         (x_get_window_property, receive_incremental_selection)
6661         (lisp_data_to_selection_data, x_property_data_to_lisp):
6662         Check for size-calculation overflow.
6663         (x_get_window_property, receive_incremental_selection)
6664         (lisp_data_to_selection_data, Fx_register_dnd_atom):
6665         Don't store size until memory allocation succeeds.
6666         (x_get_window_property): Plug memory leak on memory exhaustion.
6667         Don't double-block input; malloc is safe here.  Don't assume 2**34
6668         - 4 fits in unsigned long.  Add an xassert to check
6669         XGetWindowProperty overflow.  Be more careful about overflow
6670         calculations, and distinguish size from memory overflow better.
6671         (receive_incremental_selection): When tracing, don't assume
6672         unsigned int is less than INT_MAX.
6673         (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
6674         harmful) conversions of unsigned short to int.
6675         (lisp_data_to_selection_data): Don't assume that integers
6676         in the range -65535 through -1 fit in an X unsigned short.
6677         Don't assume that ULONG_MAX == X_ULONG_MAX.  Don't store into
6678         result parameters unless successful.  Rely on cons_to_unsigned
6679         to report problems with elements; the old code wasn't right anyway.
6680         (x_check_property_data): Check for int overflow; we cannot use
6681         a wider type due to X limits.
6682         (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
6683
6684         * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
6685
6686         * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
6687         (x_term_init): Check for size calculation overflow.
6688         (x_color_cells): Don't store size until memory allocation succeeds.
6689         (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
6690         Don't assume alloca size is less than MAX_ALLOCA.
6691         (x_term_init): Don't assume length fits in int (sprintf is limited
6692         to int size).
6693
6694         Use ptrdiff_t for composition IDs.

6753         ptrdiff_t and size_t limits.
6754
6755         * keyboard.c: Overflow, signedness and related fixes.
6756         (make_lispy_movement): Use same integer type in forward decl
6757         that is used in the definition.
6758         (read_key_sequence, keyremap_step):
6759         Change bufsize argument back to int, undoing my 2011-03-30 change.
6760         We prefer signed types, and int is wide enough here.
6761         (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6762         than TYPE_MAXIMUM (EMACS_INT) / 2.  Don't let the label size grow
6763         larger than STRING_BYTES_BOUND.  Use ptrdiff_t for Emacs string
6764         length, not size_t.  Use ptrdiff_t for index, not int.
6765         (keyremap_step, read_key_sequence): Redo bufsize check to avoid
6766         possibility of integer overflow.

6782
6783         * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

6789         (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
6790         (lookup_image): Remove unnecessary tests.
6791         (xbm_image_p): Locals are now of int, not EMACS_INT,
6792         since parse_image_check makes sure they fit into int.
6793         (png_load, gif_load, svg_load_image):
6794         Prefer int to unsigned where either will do.
6795         (tiff_handler): New function, combining the cores of the
6796         old tiff_error_handler and tiff_warning_handler.
6797         This function is rewritten to use vsnprintf and thereby avoid
6798         stack buffer overflows.  It uses only the features of vsnprintf
6799         that are common to both POSIX and native Microsoft.
6800         (tiff_error_handler, tiff_warning_handler): Use it.
6801         (tiff_load, gif_load, imagemagick_load_image):
6802         Don't assume :index value fits in 'int'.
6803         (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
6804         (imagemagick_load_image): Check that crop parameters fit into
6805         the integer types that MagickCropImage accepts.  Don't assume
6806         Vimagemagick_render_type has a nonnegative value.  Don't assume
6807         size_t fits in 'long'.
6808         (gs_load): Use printmax_t to print the widest integers possible.
6809         Check for integer overflow when computing image height and width.

6822         (handle_single_display_spec): If the display spec is of the form
6823         `(space ...)', and specifies display in the text area, return 2
6824         rather than 1.
6825         (try_cursor_movement): Check for the need to scroll more
6826         accurately, and prefer exact match for point under bidi.

6828
6829         * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6830         into disp_prop; all users changed.
6831
6832         * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
6833         DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
6834         for the text covered by the display property.

6846         (set_cursor_from_row): Consider candidate row a win if its glyph
6847         represents a newline and point is on that newline.  Fixes cursor
6848         positioning on the newline at EOL of R2L text within L2R
6849         paragraph, and vice versa.
6850         (try_cursor_movement): Check continued rows, in addition to
6851         continuation rows.  Fixes unwarranted scroll when point enters a
6852         continued line of R2L text within an L2R paragraph, or vice versa.
6853         (cursor_row_p): Consider the case of point being equal to
6854         MATRIX_ROW_END_CHARPOS.  Prevents cursor being stuck when moving
6855         from the end of a short line to the beginning of a continued line
6856         of R2L text within L2R paragraph.
6857         (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

6883         * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6884         instead of CHAR_TO_BYTE.  Fixes a crash when a completion
6885         candidate is selected by the mouse, and that candidate has a
6886         composed character under the mouse.
6887
6888         * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1.  Fixes pixel

6917         from an Org mode buffer to a Speedbar frame.
6918
6919         * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from

7023         * nsterm.m (sendEvent): If event is NSApplicationDefined and
7024         data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7025         the event loop (Bug#7276).
7026
7027 2011-08-14  Andreas Schwab  <schwab@linux-m68k.org>
7028
7029         * gnutls.c (QCgnutls_bootprop_priority)
7030         (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
7031         (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
7032         (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

7034         (QCgnutls_bootprop_verify_hostname_error)
7035         (QCgnutls_bootprop_callbacks_verify): Rename from
7036         Qgnutls_bootprop_..., all uses changed.
7037
7038         * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
7039         uses changed.
7040
7041 2011-08-14  Paul Eggert  <eggert@cs.ucla.edu>
7042
7043         * xfaces.c (Qframe_set_background_mode): Now static.
7044         * dispextern.h (Qframe_set_background_mode): Remove decl.
7045
7046         * process.c (Fnetwork_interface_info): Declare local only if needed.
7047
7048 2011-08-13  Jan Djärv  <jan.h.d@swipnet.se>
7049
7050         * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7051         (Fnetwork_interface_list): Allocate in increments of bytes instead
7052         of sizeof (struct ifreq).  Iterate over ifconf.ifc_req by counting
7053         bytes (Bug#8477).  Count bytes correctly when ifr_addr is a struct
7054         sockaddr.
7055         (struct ifflag_def): notrailers is smart on OSX.
7056         (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7057         Get hardware address with getifaddrs if available.
7058
7059 2011-08-12  Eli Zaretskii  <eliz@gnu.org>
7060
7061         * xdisp.c (iterate_out_of_display_property): xassert that
7062         IT->position is set to within IT->object's boundaries.  Break from
7063         the loop as soon as EOB is reached; avoids infloops in redisplay
7064         when IT->position is set up wrongly due to some bug.
7065         Set IT->current to match the bidi iterator unconditionally.
7066         (push_display_prop): Allow GET_FROM_STRING as IT->method on
7067         entry.  Force push_it to save on the stack the current
7068         buffer/string position, to be restored by pop_it.  Fix flags in
7069         the iterator structure wrt the object coming from a display
7070         property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7071         properties.  (Bug#9284)
7072
7073 2011-08-09  Andreas Schwab  <schwab@linux-m68k.org>

7088         no-display-properties-and-no-overlays under bidi display.
7089         Set disp_pos in the bidi iterator to avoid searches for display
7090         properties and overlays.

7098         the font entity extracted from the cache (Bug#8109).
7099
7100 2011-08-07  Chong Yidong  <cyd@stupidchicken.com>
7101
7102         * composite.c (autocmp_chars): Don't reset point.  That is done by

7104
7105 2011-08-07  Juri Linkov  <juri@jurta.org>
7106
7107         * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7108         to show the arg `TIME' instead of `TIMEVAL'.
7109

7111
7112         * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7113         display property strides EOL and includes a newline, as in
7114         longlines-mode.  (Bug#9254)
7115         (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7116         word-wrap under bidirectional display.  (Bug#9224)
7117
7118         * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7119         is non-zero, even if the data buffer is NULL.  Fixes a crash in
7120         vertical-motion with longlines-mode.  (Bug#9254)

7126
7127         * xdisp.c (display_line): Release buffer allocated for shelved bidi
7128         cache.  (Bug#9221)
7129
7130         * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7131         amount allocated this far in `bidi_cache_total_alloc'.
7132         (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7133         non-zero, only free the data buffer without restoring the cache
7134         contents.  All callers changed.
7135
7136         * dispextern.h (bidi_unshelve_cache): Update prototype.

7141         to xfree to an equivalent call to bidi_unshelve_cache.
7142         (move_it_in_display_line_to): Fix logic of returning
7143         MOVE_POS_MATCH_OR_ZV in the bidi case.  (Bug#9224)

7149
7150 2011-08-04  Jan Djärv  <jan.h.d@swipnet.se>
7151
7152         * Makefile.in (LIB_PTHREAD): New variable.
7153         (LIBES): Add LIB_PTHREAD (Bug#9216).
7154
7155         * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7156         Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).

7163
7164         * xterm.c (x_find_topmost_parent): New function.
7165         (x_set_frame_alpha): Find topmost parent window with
7166         x_find_topmost_parent and set the property there also (bug#9181).

7168
7169 2011-08-04  Paul Eggert  <eggert@cs.ucla.edu>
7170

7179
7180         * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
7181         so that it is not optimized away.
7182
7183         * xdisp.c (compute_display_string_pos): Remove unused local.
7184
7185 2011-08-02  Eli Zaretskii  <eliz@gnu.org>
7186
7187         Fix slow cursor motion and scrolling in large buffers with
7188         selective display, like Org Mode buffers.  (Bug#9218)
7189
7190         * dispextern.h (struct bidi_it): New member disp_prop_p.
7191
7192         * xdisp.c: Remove one-slot cache of display string positions.
7193         (compute_display_string_pos): Accept an additional argument
7194         DISP_PROP_P; callers changed.  Scan at most 5K characters forward
7195         for a display string or property.  If found, set DISP_PROP_P
7196         non-zero.
7197
7198         * bidi.c (bidi_fetch_char): Accept an additional argument
7199         DISP_PROP_P, and pass it to compute_display_string_pos.
7200         Only handle text covered by a display string if DISP_PROP_P is returned
7201         non-zero.  All callers of bidi_fetch_char changed.
7202
7203 2011-08-02  Stefan Monnier  <monnier@iro.umontreal.ca>
7204
7205         * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

7208
7209         * keymap.c (Fdefine_key): Fix non-prefix key error message when

7211
7212 2011-08-02  Kenichi Handa  <handa@m17n.org>

7219
7220         * xdisp.c (forward_to_next_line_start): Accept additional argument

7222         on the newline.
7223         (reseat_at_next_visible_line_start): Use the bidi iterator state
7224         returned by forward_to_next_line_start to restore the state of
7225         it->bidi_it after backing up to previous newline.  (Bug#9212)
7226
7227 2011-07-30  Andreas Schwab  <schwab@linux-m68k.org>
7228

7232
7233 2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>
7234
7235         * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7236         This is needed if max-image-size is a floating-point number.
7237
7238 2011-07-28  Andreas Schwab  <schwab@linux-m68k.org>
7239
7240         * print.c (print_object): Print empty symbol as ##.

7245
7246         * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7247         setting frame foreground color (Bug#9175).
7248         (x_set_background_color): Likewise.
7249
7250         * nsmenu.m (-setText): Size tooltip dimensions precisely to
7251         contents (Bug#9176).
7252         (EmacsTooltip -init): Remove bezels and add shadows to
7253         tooltip windows.
7254
7255         * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7256         or scroll bar (Bug#8470).
7257
7258         * nsfont.m (nsfont_open): Remove assignment to voffset and
7259         unnecessary vars hshink, expand, hd, full_height, min_height.
7260         (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7261
7262         * nsterm.h (nsfont_info): Remove voffset field.
7263
7264 2011-07-28  Alp Aker  <alp.tekin.aker@gmail.com>
7265
7266         Implement strike-through and overline on NextStep (Bug#8863).
7267
7268         * nsfont.m (nsfont_open): Use underline position provided by font,
7269         instead of hard-coded value of 2.
7270         (nsfont_draw): Call ns_draw_text_decoration instead.
7271
7272         * nsterm.h: Add declaration for ns_draw_text_decoration.
7273
7274         * nsterm.m (ns_draw_text_decoration): New function for drawing
7275         underline, overline, and strike-through.
7276         (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
7277         ns_draw_text_decoration.  Change treatment of cursor drawing to
7278         accommodate underlining, etc.
7279
7280 2011-07-28  Eli Zaretskii  <eliz@gnu.org>
7281
7282         * buffer.c (init_buffer_once): Set bidi-display-reordering to t by

7284
7285 2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>
7286
7287         * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7288         Without this fix, if a signal arrives just after memory fills up,
7289         'malloc' might be invoked reentrantly.
7290
7291         * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7292         In other words, assume that every image size is allowed, on non-X
7293         hosts.  This assumption is probably wrong, but it lets Emacs compile.
7294
7295 2011-07-28  Andreas Schwab  <schwab@linux-m68k.org>
7296
7297         * regex.c (re_iswctype): Convert return values to boolean.

7300
7301         * xdisp.c (compute_display_string_pos): Don't use cached display
7302         string position if the buffer had its restriction changed.
7303         (Bug#9184)
7304
7305 2011-07-28  Paul Eggert  <eggert@cs.ucla.edu>
7306

7310
7311         Integer signedness and overflow and related fixes.  (Bug#9079)
7312
7313         * bidi.c: Integer size and overflow fixes.
7314         (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7315         (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7316         (bidi_cache_find_level_change, bidi_cache_ensure_space)
7317         (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7318         (bidi_find_other_level_edge):
7319         Use ptrdiff_t instead of EMACS_INT where either will do.
7320         This works better on 32-bit hosts configured --with-wide-int.
7321         (bidi_cache_ensure_space): Check for size-calculation overflow.
7322         Use % rather than repeated addition, for better worst-case speed.
7323         Don't set bidi_cache_size until after xrealloc returns, because it
7324         might not return.
7325         (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7326         (bidi_cache_ensure_space): Also check that the bidi cache size
7327         does not exceed that of the largest Lisp string or buffer.  See Eli
7328         Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7329
7330         * alloc.c (__malloc_size_t): Remove.
7331         All uses replaced by size_t.  See Andreas Schwab's note
7332         <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7333
7334         * image.c: Improve checking for integer overflow.
7335         (check_image_size): Assume that f is nonnull, since
7336         it is always nonnull in practice.  This is one less thing to
7337         worry about when checking for integer overflow later.
7338         (x_check_image_size): New function, which checks for integer
7339         overflow issues inside X.
7340         (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7341         This removes the need for a memory_full check.
7342         (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7343         (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7344         (xbm_read_bitmap_data): Change locals back to 'int', since
7345         their values must fit in 'int'.
7346         (xpm_load_image, png_load, tiff_load):
7347         Invoke x_create_x_image_and_pixmap earlier,
7348         to avoid much needless work if the image is too large.
7349         (tiff_load): Treat overly large images as if
7350         x_create_x_image_and_pixmap failed, not as malloc failures.
7351         (gs_load): Use x_check_image_size.
7352
7353         * gtkutil.c: Omit integer casts.
7354         (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7355         (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7356
7357         * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7358
7359         * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7360         Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7361         would wrongly return t on a 64-bit host.
7362
7363         * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7364         The plain *_OVERFLOW macros run afoul of GCC bug 49705
7365         <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7366         and therefore cause GCC to emit a bogus diagnostic in some cases.
7367
7368         * image.c: Integer signedness and overflow and related fixes.
7369         This is not an exhaustive set of fixes, but it's time to
7370         record what I've got.
7371         (lookup_pixel_color, check_image_size): Remove redundant decls.
7372         (check_image_size): Don't assume that arbitrary EMACS_INT values
7373         fit in 'int', or that arbitrary 'double' values fit in 'int'.
7374         (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7375         (tiff_load, imagemagick_load_image):
7376         Check for overflow in size calculations.
7377         (x_create_x_image_and_pixmap): Remove unnecessary test for
7378         xmalloc returning NULL; that can't happen.
7379         (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7380         (xpm_color_bucket): Use better integer hashing function.
7381         (xpm_cache_color): Don't possibly over-allocate memory.
7382         (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7383         (gif_memory_source):
7384         Use ptrdiff_t, not int or size_t, to record sizes.
7385         (png_load): Don't assume values greater than 2**31 fit in 'int'.
7386         (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7387         either works, as we prefer signed integers.
7388         (tiff_read_from_memory, tiff_write_from_memory):
7389         Return tsize_t, not size_t, since that's what the TIFF API wants.
7390         (tiff_read_from_memory): Don't fail simply because the read would
7391         go past EOF; instead, return a short read.
7392         (tiff_load): Omit no-longer-needed casts.
7393         (Fimagemagick_types): Don't assume size fits into 'int'.
7394
7395         Improve hashing quality when configured --with-wide-int.
7396         * fns.c (hash_string): New function, taken from sxhash_string.
7397         Do not discard information about ASCII character case; this
7398         discarding is no longer needed.
7399         (sxhash-string): Use it.  Change sig to match it.  Caller changed.
7400         * lisp.h: Declare it.
7401         * lread.c (hash_string): Remove, since we now use fns.c's version.
7402         The fns.c version returns a wider integer if --with-wide-int is
7403         specified, so this should help the quality of the hashing a bit.
7404
7405         * emacs.c: Integer overflow minor fix.
7406         (heap_bss_diff): Now uprintmax_t, not unsigned long.  All used changed.
7407         Define only if GNU_LINUX.
7408         (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7409
7410         * dispnew.c: Integer signedness and overflow fixes.
7411         Remove unnecessary forward decls, that were a maintenance hassle.
7412         (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7413         All uses changed.
7414         (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7415         (scrolling_window): Use ptrdiff_t, not int, for byte count.
7416         (prepare_desired_row, line_draw_cost):
7417         Use int, not unsigned, where either works.
7418         (save_current_matrix, restore_current_matrix):
7419         Use ptrdiff_t, not size_t, where either works.
7420         (init_display): Check for overflow more accurately, and without
7421         relying on undefined behavior.
7422
7423         * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7424         Remove, replacing with the new symbols in lisp.h.  All uses changed.
7425         * fileio.c (make_temp_name):
7426         * filelock.c (lock_file_1, lock_file):
7427         * xdisp.c (message_dolog):
7428         Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7429         Use pMd etc. instead.
7430         * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7431         replacing the pWIDE etc. symbols removed from editfns.c.
7432
7433         * keyboard.h (num_input_events): Now uintmax_t.
7434         This is (very slightly) less likely to mess up due to wraparound.
7435         All uses changed.
7436
7437         * buffer.c: Integer signedness fixes.
7438         (alloc_buffer_text, enlarge_buffer_text):
7439         Use ptrdiff_t rather than size_t when either will do, as we prefer
7440         signed integers.
7441
7442         * alloc.c: Integer signedness and overflow fixes.
7443         Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7444         (__malloc_size_t): Default to size_t, not to int.
7445         (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7446         (Fgarbage_collect, mark_object_loop_halt, mark_object):
7447         Prefer ptrdiff_t to size_t when either would do, as we prefer
7448         signed integers.
7449         (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7450         (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7451         Now const.  Initialize with values that are in range even if char
7452         is signed.
7453         (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7454         (xmalloc_put_size, xmalloc_get_size): New functions.  All uses changed.
7455         These functions do the right thing with sizes > 2**32.
7456         (check_depth): Now ptrdiff_t, not int.
7457         (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7458         Adjust to new way of storing sizes.  Check for size overflow bugs
7459         in rest of code.
7460         (STRING_BYTES_MAX): Adjust to new overheads.  The old code was
7461         slightly wrong anyway, as it missed one instance of
7462         XMALLOC_OVERRUN_CHECK_OVERHEAD.
7463         (refill_memory_reserve): Omit needless cast to size_t.
7464         (mark_object_loop_halt): Mark as externally visible.
7465
7466         * xselect.c: Integer signedness and overflow fixes.
7467         (Fx_register_dnd_atom, x_handle_dnd_message):
7468         Use ptrdiff_t, not size_t, since we prefer signed.
7469         (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7470         * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7471         x_dnd_atoms_size and x_dnd_atoms_length.
7472
7473         * doprnt.c: Prefer signed to unsigned when either works.
7474         * eval.c (verror):
7475         * doprnt.c (doprnt):
7476         * lisp.h (doprnt):
7477         * xdisp.c (vmessage):
7478         Use ptrdiff_t, not size_t, when using or implementing doprnt,
7479         since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7480         prefer signed arithmetic to avoid comparison confusion.
7481         * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7482         but is a bit tricky.
7483
7484         Assume freestanding C89 headers, string.h, stdlib.h.
7485         * data.c, doprnt.c, floatfns.c, print.c:
7486         Include float.h unconditionally.
7487         * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7488         limits.h, stddef.h, string.h.  Use memset instead of 'flood'.
7489         * regex.c: Likewise for stddef.h, string.h.
7490         (ISASCII): Remove; can assume it returns 1 now.  All uses removed.
7491         * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7492         * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7493         (STDC_HEADERS): Remove obsolete defines.
7494         * sysdep.c: Include limits.h unconditionally.
7495
7496         Assume support for memcmp, memcpy, memmove, memset.
7497         * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7498         * regex.c (memcmp, memcpy):
7499         Remove; we assume C89 now.
7500
7501         * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7502         (__malloc_safe_bcopy): Remove; no longer needed.
7503
7504         * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7505         Use EMACS_INT, not EMACS_UINT, for sizes.  The code works equally
7506         well either way, and we prefer signed to unsigned.
7507
7508 2011-07-27  Lars Magne Ingebrigtsen  <larsi@gnus.org>
7509
7510         * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7511         closes the connection while we're reading (bug#9182).
7512
7513 2011-07-25  Jan Djärv  <jan.h.d@swipnet.se>
7514
7515         * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7516         are specified (Bug#9168).
7517
7518 2011-07-25  Paul Eggert  <eggert@cs.ucla.edu>
7519
7520         * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7521         Found by GCC static checking and --with-wide-int on a 32-bit host.
7522
7523 2011-07-25  Eli Zaretskii  <eliz@gnu.org>
7524
7525         * xdisp.c (compute_display_string_pos): Fix logic of caching
7526         previous display string position.  Initialize cached_prev_pos to
7527         -1.  Fixes slow-down at the beginning of a buffer.
7528
7529 2011-07-24  Eli Zaretskii  <eliz@gnu.org>
7530
7531         * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7532         for attrs[LFACE_FONTSET_INDEX].
7533
7534 2011-07-23  Paul Eggert  <eggert@cs.ucla.edu>
7535
7536         * xml.c (parse_region): Remove unused local
7537         that was recently introduced.
7538
7539 2011-07-23  Eli Zaretskii  <eliz@gnu.org>
7540
7541         * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7542         2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7543
7544         * xdisp.c (move_it_in_display_line_to): Record the best matching
7545         position for TO_CHARPOS while scanning the line, and restore it on
7546         exit if none of the characters scanned was an exact match.
7547         Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7548         when exact match is impossible due to invisible text, and the
7549         lines are truncated.
7550
7551 2011-07-23  Jan Djärv  <jan.h.d@swipnet.se>
7552
7553         * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7554         for OSX >= 10.7.
7555
7556 2011-07-22  Eli Zaretskii  <eliz@gnu.org>
7557
7558         Fix a significant slow-down of cursor motion with C-n, C-p,
7559         C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7560         auto-repeat under bidi redisplay in fontified buffers.
7561         * xdisp.c (compute_stop_pos_backwards): New function.
7562         (next_element_from_buffer): Call compute_stop_pos_backwards to
7563         find a suitable prev_stop when we find ourselves before
7564         base_level_stop.
7565         (reseat): Don't look for prev_stop, as that could mean a very long
7566         run.
7567         <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7568         <cached_disp_overlay_modiff>: Cache for last found display string
7569         position.
7570         (compute_display_string_pos): Return the cached position if asked
7571         about the same buffer in the same area of character positions, and
7572         the buffer wasn't changed since the time the display string
7573         position was cached.
7574
7575 2011-07-22  Eli Zaretskii  <eliz@gnu.org>
7576
7577         * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7578         is an integer, which is important for empty lines.  (Bug#9149)
7579
7580 2011-07-22  Chong Yidong  <cyd@stupidchicken.com>
7581
7582         * frame.c (Fmodify_frame_parameters): In tty case, update the
7583         default face if necessary (Bug#4238).
7584
7585 2011-07-21  Chong Yidong  <cyd@stupidchicken.com>
7586
7587         * editfns.c (Fstring_to_char): No need to explain what a character
7588         is in the docstring (Bug#6576).
7589
7590 2011-07-20  Lars Magne Ingebrigtsen  <larsi@gnus.org>
7591
7592         * xml.c (parse_region): Make sure we always return a tree.
7593
7594 2011-07-20  HAMANO Kiyoto  <khiker.mail@gmail.com>
7595
7596         * xml.c (parse_region): If a document contains only comments,
7597         return that, too.
7598
7599 2011-07-20  Lars Magne Ingebrigtsen  <larsi@gnus.org>
7600
7601         * xml.c (make_dom): Return comments, too.
7602
7603 2011-07-19  Paul Eggert  <eggert@cs.ucla.edu>
7604
7605         Port to OpenBSD.
7606         See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7607         and the surrounding thread.
7608         * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7609         rather than fgets, and retry after EINTR.  Otherwise, 'emacs
7610         --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7611         timer goes off.
7612         * s/openbsd.h (BROKEN_SIGIO): Define.
7613         * unexelf.c (unexec) [__OpenBSD__]:
7614         Don't update the .mdebug section of the Alpha COFF symbol table.
7615
7616 2011-07-19  Lars Magne Ingebrigtsen  <larsi@gnus.org>
7617
7618         * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7619         (bug#8460).
7620
7621 2011-07-18  Paul Eggert  <eggert@cs.ucla.edu>
7622
7623         * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7624         This fixes some race conditions on the permissions of any newly
7625         created file.
7626
7627         * alloc.c (valid_pointer_p): Use pipe, not open.
7628         This fixes some permissions issues when debugging.
7629
7630         * fileio.c (Fcopy_file): Adjust mode if fchown fails.  (Bug#9002)
7631         If fchown fails to set both uid and gid, try to set just gid,
7632         as that is sometimes allowed.  Adjust the file's mode to eliminate
7633         setuid or setgid bits that are inappropriate if fchown fails.
7634
7635 2011-07-18  Stefan Monnier  <monnier@iro.umontreal.ca>
7636
7637         * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7638         to compare Lisp_Objects.
7639         * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7640         global_gnutls_log_level, don't mistake it for a Lisp_Object.
7641         (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7642
7643 2011-07-17  Andreas Schwab  <schwab@linux-m68k.org>
7644
7645         * lread.c (read_integer): Unread even EOF character.
7646         (read1): Likewise.  Properly record start position of symbol.
7647
7648         * lread.c (read1): Read `#:' as empty uninterned symbol if no
7649         symbol character follows.
7650
7651 2011-07-17  Paul Eggert  <eggert@cs.ucla.edu>
7652
7653         * fileio.c (Fcopy_file): Pacify gcc re fchown.  (Bug#9002)
7654         This works around a problem with the previous change to Fcopy_file.
7655         Recent glibc declares fchown with __attribute__((warn_unused_result)),
7656         and without this change, GCC might complain about discarding
7657         fchown's return value.
7658
7659 2011-07-16  Juanma Barranquero  <lekktu@gmail.com>
7660
7661         * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7662
7663 2011-07-16  Paul Eggert  <eggert@cs.ucla.edu>
7664
7665         * fileio.c (Fcopy_file): Don't diagnose fchown failures.  (Bug#9002)
7666
7667 2011-07-16  Lars Magne Ingebrigtsen  <larsi@gnus.org>
7668
7669         * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7670         it's used from the C level.
7671
7672         * process.c: Use the same condition for POLL_FOR_INPUT in both
7673         keyboard.c and process.c (bug#1858).

7685
7686         * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7687         quotes the next character, and doesn't affect other longer
7688         sequences (bug#8935).
7689
7690         * lread.c (syms_of_lread): Clarify that is isn't only
7691         `eval-buffer' and `eval-defun' that's affected by
7692         `lexical-binding' (bug#8460).

7700
7701         Fix minor problems found by static checking.
7702         * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7703         (elsz): Now a signed constant, not a size_t var.  We prefer signed
7704         types to unsigned, to avoid integer comparison confusion.  Without
7705         this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7706         "cannot optimize loop, the loop counter may overflow", a symptom
7707         of the confusion.
7708         * indent.c (Fvertical_motion): Mark locals as initialized.
7709         * xdisp.c (reseat_to_string): Fix pointer signedness issue.

7733         (init_iterator): Call bidi_init_it only of a valid
7734         buffer position was specified.  Initialize paragraph_embedding to

7736         (reseat_to_string): Initialize the bidi iterator.
7737         (display_string): If we need to ignore text properties of
7738         LISP_STRING, set IT->stop_charpos to IT->end_charpos.  (The
7739         original value of -1 will not work with bidi.)
7740         (compute_display_string_pos): First arg is now struct
7741         `text_pos *'; all callers changed.  Support display properties on
7742         Lisp strings.
7743         (compute_display_string_end): Support display properties on Lisp
7744         strings.
7745         (init_iterator, reseat_1, reseat_to_string): Initialize the
7746         string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7747         when iterating on a string not from display properties).
7748         (compute_display_string_pos, compute_display_string_end):
7749         Fix calculation of the object to scan.  Fixes an error when using
7750         arrow keys.
7751         (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7752         base_level_stop; instead, set base_level_stop to BEGV.
7753         Fixes crashes in vertical-motion.
7754         (next_element_from_buffer): Improve commentary for when
7755         the iterator is before prev_stop.
7756         (init_iterator): Initialize bidi_p from the default value of
7757         bidi-display-reordering, not from buffer-local value.  Use the
7758         buffer-local value only if initializing for buffer iteration.
7759         (handle_invisible_prop): Support invisible properties on strings
7760         that are being bidi-reordered.

7776         (next_element_from_c_string): Handle the case of the first string
7777         character that is not the first one in the visual order.
7778         (get_visually_first_element): New function, refactored from common
7779         parts of next_element_from_buffer, next_element_from_string, and
7780         next_element_from_c_string.
7781         (tool_bar_lines_needed, redisplay_tool_bar)
7782         (display_menu_bar): Force left-to-right direction.  Add a FIXME
7783         comment for making that be controlled by a user option.
7784         (push_it, pop_it): Save and restore the state of the
7785         bidi iterator.  Save and restore the bidi_p flag.

7795         bidi-iterating.
7796         (back_to_previous_visible_line_start): If handle_display_prop
7797         pushed the iterator stack, restore the internal state of the bidi
7798         iterator by calling bidi_pop_it same number of times.
7799         (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
7800         and we are bidi-iterating, don't decrement the iterator position;
7801         instead, set the first_elt flag in the bidi iterator, to produce
7802         the same effect.

7808         (push_display_prop): Set up the `unibyte' member of bidi_it.string
7809         correctly.  Don't assume unibyte strings are not bidi-reordered.

7825         iterator with IT's position.  (Bug#7616)
7826         (find_row_edges): If ROW->start.pos gives position

7846         displayed in margins.  (Bug#8133) (Bug#8867)
7847         Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
7848         TO_CHARPOS.

8274         Random fixes.  E.g., (random) never returned negative values.
8275         * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8276         subseconds part to the entropy, as that's a bit more random.
8277         Prefer signed to unsigned, since the signedness doesn't matter and
8278         in general we prefer signed.  When given a limit, use a
8279         denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8280         latter isn't right if USE_2_TAGS_FOR_INTS.
8281         * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8282         not 0..VALMASK.  Don't discard "excess" bits that random () returns.

8293
8294         * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.

8303         is a directory before asking whether to use the file name
8304         (bug#7564).
8305         (barf_or_query_if_file_exists): Make the "File is a directory"
8306         error be more correct.
8307
8308         * fns.c (Frequire): Remove the mention of the .gz files, since
8309         that's installation-specific, but keep the mention of
8310         `get-load-suffixes'.

8320         (syms_of_gnutls): Remove duplicate DEFSYM for
8321         Qgnutls_bootprop_verify_hostname_error, an error for
8322         Qgnutls_bootprop_verify_error (which is no longer used).
8323
8324         * eval.c (find_handler_clause): Remove parameters `sig' and `data',
8325         unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca.  All callers changed.
8326         Also (re)move comments that are misplaced or no longer relevant.

8344         No need to define when HAVE_GSETTINGS || !HAVE_XFT.
8345
8346         * keymap.c (access_keymap_1): Now static.
8347
8348 2011-07-02  Chong Yidong  <cyd@stupidchicken.com>
8349
8350         * keyboard.c (command_loop_1): If a down-mouse event is unbound,

8389         (syms_of_keymap): Defsubr make-composed-keymap.

8403
8404         * xsettings.c (store_monospaced_changed): Take new font as arg and
8405         check for change against current_mono_font.
8406         (EMACS_TYPE_SETTINGS): Remove this and related defines.
8407         (emacs_settings_constructor, emacs_settings_get_property)

8412         with value as argument.
8413         (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
8414         g_settings_new (Bug#8967).  Do not create gsettings_obj.

8426
8427         * eval.c (struct backtrace): Simplify and port the data structure.
8428         Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8429         signed bit field, as this assumption is not portable and it makes
8430         Emacs crash when compiled with Sun C 5.8 on sparc.  Do not use
8431         "char debug_on_exit : 1" as this is not portable either; instead,
8432         use the portable "unsigned int debug_on_exit : 1".  Remove unused
8433         member evalargs.  Remove obsolete comments about cc bombing out.

8470         clearly which files are directly included by each source file,

8604
8605         * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
8606         for sizes.  Check for string overflow more accurately.
8607         Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
8608
8609         * macros.c: Integer and buffer overflow fixes.
8610         * keyboard.h (struct keyboard.kbd_macro_bufsize):

8616
8617         * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
8618
8619         * lread.c: Integer overflow fixes.
8620         (read_integer): Radix is now EMACS_INT, not int,
8621         to improve quality of diagnostics for out-of-range radices.
8622         Calculate buffer size correctly for out-of-range radices.
8623         (read1): Check for integer overflow in radices, and in
8624         read-circle numbers.
8625         (read_escape): Avoid int overflow.

8636         (prev_saved_doc_string_size, prev_saved_doc_string_length):
8637         Now ptrdiff_t, not int.
8638         (read1): Don't assume doc string length fits in int.  Check for
8639         out-of-range doc string lengths.

8649
8650         Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8651         The following patches are for when GLYPH_DEBUG && !XASSERT.
8652         * dispextern.h (trace_redisplay_p, dump_glyph_string):
8653         * dispnew.c (flush_stdout):
8654         * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8655         Mark as externally visible.
8656         * dispnew.c (check_window_matrix_pointers): Now static.
8657         * dispnew.c (window_to_frame_vpos):
8658         * xfns.c (unwind_create_frame):
8659         * xterm.c (x_check_font): Remove unused local.
8660         * scroll.c (CHECK_BOUNDS):
8661         * xfaces.c (cache_fache): Rename local to avoid shadowing.
8662         * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8663         * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8664         (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8665         (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8666         Now static.
8667         (debug_method_add): Use va_list and vsprintf rather than relying
8668         on undefined behavior with wrong number of arguments.
8669         (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8670         Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8671         In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8672         since we're not interested in debugging glyphs with old libraries.
8673         * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8674         GCC 4.6.0's static checking.
8675
8676 2011-06-22  Paul Eggert  <eggert@cs.ucla.edu>
8677

8692         * xfaces.c (load_pixmap):

8695         (.bitmaps_last, struct x_output.icon_bitmap):
8696         Use ptrdiff_t, not int, for bitmap indexes.
8697         (x_allocate_bitmap_record): Check for size overflow.
8698         * dispextern.h, lisp.h: Adjust to API changes elsewhere.
8699
8700         Use ptrdiff_t, not int, for overlay counts.
8701         * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
8702         * editfns.c (overlays_around, get_pos_property):
8703         * textprop.c (get_char_property_and_overlay):
8704         * xdisp.c (next_overlay_change, note_mouse_highlight):
8705         * xfaces.c (face_at_buffer_position):
8706         * buffer.c (OVERLAY_COUNT_MAX): New macro.
8707         (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8708         (Fnext_overlay_change, Fprevious_overlay_change)
8709         (mouse_face_overlay_overlaps, Foverlays_in):
8710         Use ptrdiff_t, not int, for sizes.
8711         (overlays_at, overlays_in): Check for size-calculation overflow.
8712
8713         * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8714
8715         * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8716         (x_session_initialize): Do not assume string length fits in int.
8717
8718         * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8719         This is unlikely, but can occur if DPI is outlandish.
8720
8721         * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8722         * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8723
8724         * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8725         * xrdb.c (magic_file_p, search_magic_path):
8726         Omit last arg SUFFIX; it was always 0.  All callers changed.
8727         (magic_file_p): Use ptrdiff_t, not int.  Check for size overflow.
8728
8729         * xfont.c (xfont_match): Avoid need for strlen.
8730
8731         * xfns.c: Don't assume strlen fits in int.

8733
8734         * xdisp.c (message_log_check_duplicate): Return intmax_t,
8735         not unsigned long, as we prefer signed integers.  All callers changed.
8736         Detect integer overflow in repeat count.
8737         (message_dolog): Don't assume print length fits in 39 bytes.
8738         (display_mode_element): Don't assume strlen fits in int.
8739
8740         * termcap.c: Don't assume sizes fit in int and never overflow.
8741         (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8742         (gobble_line): Check for size-calculation overflow.
8743
8744         * minibuf.c (Fread_buffer):
8745         * lread.c (intern, intern_c_string):
8746         * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8747         Don't assume string length fits in int.
8748
8749         * keyboard.c (parse_tool_bar_item):
8750         * gtkutil.c (style_changed_cb): Avoid need for strlen.
8751
8752         * font.c: Don't assume string length fits in int.
8753         (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
8754         Use ptrdiff_t, not int.
8755         (font_intern_prop): Don't assume string length fits in int.
8756         Don't assume integer property fits in fixnum.
8757         * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
8758
8759         * filelock.c: Fix some buffer overrun and integer overflow issues.
8760         (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8761         Reformulate so as not to need the command string.
8762         Invoke gzip -cd rather than gunzip, as it's more portable.
8763         (lock_info_type, lock_file_1, lock_file):
8764         Don't assume pid_t and time_t fit in unsigned long.
8765         (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8766         (current_lock_owner): Prefer signed type for sizes.
8767         Use memcpy, not strncpy, where memcpy is what is really wanted.
8768         Don't assume (via atoi) that time_t and pid_t fit in int.
8769         Check for time_t and/or pid_t out of range, e.g., via a network share.
8770         Don't alloca where an auto var works fine.
8771
8772         * fileio.c: Fix some integer overflow issues.
8773         (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8774         Don't assume string length fits in int.
8775         (directory_file_name): Don't assume string length fits in long.
8776         (make_temp_name): Don't assume pid fits in int, or that its print
8777         length is less than 20.
8778
8779         * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8780
8781         * coding.c (make_subsidiaries): Don't assume string length fits in int.
8782
8783         * callproc.c (child_setup): Rewrite to avoid two strlen calls.
8784
8785         * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
8786         We prefer signed integers, even for size calculations.
8787
8788         * emacs.c: Don't assume string length fits in 'int'.
8789         (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
8790         (main): Don't invoke strlen when not needed.
8791
8792         * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
8793         (XD_DEBUG_MESSAGE): Don't waste a byte.

8796         (Fgetenv_internal):
8797         * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8798
8799         * lread.c (invalid_syntax): Omit length argument.
8800         All uses changed.  This doesn't fix a bug, but it simplifies the
8801         code away from its former Hollerith-constant appearance, and it's
8802         one less 'int' to worry about when looking at integer-overflow issues.
8803         (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8804
8805         * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8806         This didn't break anything, but it didn't help either.
8807         It's confusing to put a bogus integer in a place where the actual
8808         value does not matter.
8809         (LIST_END_P): Remove unused macro and its bogus comment.
8810         (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8811
8812         * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8813         This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8814         implementation.
8815         (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8816         We prefer signed types, and the value cannot exceed the EMACS_INT
8817         range anyway (because otherwise the length would not be representable).
8818         (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8819         not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8820         This avoids a GCC warning when WIDE_EMACS_INT.
8821
8822         * indent.c (sane_tab_width): New function.
8823         (current_column, scan_for_column, Findent_to, position_indentation)
8824         (compute_motion): Use it.  This is just for clarity.
8825         (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8826
8827         * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8828
8829         * lisp.h (lint_assume): New macro.
8830         * composite.c (composition_gstring_put_cache):
8831         * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8832
8833         * editfns.c, insdel.c:
8834         Omit unnecessary forward decls, to simplify future changes.
8835
8836         * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8837
8838         * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8839
8840         * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8841         Use much-faster test for byte-length change.
8842         Don't assume string byte-length fits in 'int'.
8843         Check that character arg fits in 'int'.
8844         (mapcar1): Declare byte as byte, for clarity.
8845
8846         * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8847
8848         * fns.c (concat): Catch string overflow earlier.
8849         Do not rely on integer wraparound.
8850
8851         * dispextern.h (struct it.overlay_strings_charpos)
8852         (struct it.selective): Now EMACS_INT, not int.
8853         * xdisp.c (forward_to_next_line_start)
8854         (back_to_previous_visible_line_start)
8855         (reseat_at_next_visible_line_start, next_element_from_buffer):
8856         Don't arbitrarily truncate the value of 'selective' to int.
8857
8858         * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8859
8860         * composite.c: Don't truncate sizes to 'int'.
8861         (composition_gstring_p, composition_reseat_it)
8862         (composition_adjust_point): Use EMACS_INT, not int.
8863         (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8864         not EMACS_UINT, for indexes.
8865
8866         * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8867
8868         * buffer.c: Include <verify.h>.
8869         (struct sortvec.priority, struct sortstr.priority):
8870         Now EMACS_INT, not int.
8871         (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8872         (struct sortstr.size, record_overlay_string)
8873         (struct sortstrlist.size, struct sortlist.used):
8874         Don't truncate size to int.
8875         (record_overlay_string): Check for size-calculation overflow.
8876         (init_buffer_once): Check at compile-time, not run-time.

8879
8880         Don't leak an XBM-image-sized buffer
8881         * image.c (xbm_load): Free the image buffer after using it.

8884
8885         Port to Sun C.
8886         * composite.c (find_automatic_composition): Omit needless 'return 0;'
8887         that Sun C diagnosed.
8888         * fns.c (secure_hash): Fix pointer signedness issue.

8896         sha512.h.
8897
8898         * fns.c (secure_hash): Rename from crypto_hash_function and change
8899         the first arg to accept symbols.
8900         (Fsecure_hash): New primitive.
8901         (syms_of_fns): New symbols.

8927
8928         * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8929         Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8930         hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8931
8932         Improve buffer-overflow checking (Bug#8873).
8933         * fileio.c (Finsert_file_contents):
8934         * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8935         Remove the old (too-loose) buffer overflow checks.
8936         They weren't needed, since make_gap checks for buffer overflow.
8937         * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8938         The old code merely checked for Emacs fixnum overflow, and relied
8939         on undefined (wraparound) behavior.  The new code avoids undefined
8940         behavior, and also checks for ptrdiff_t and/or size_t overflow.
8941
8942         * editfns.c (Finsert_char): Don't dump core with very negative counts.
8943         Tune.  Don't use wider integers than needed.  Don't use alloca.
8944         Use a bigger 'string' buffer.  Rewrite to avoid 'n > 0' test.
8945
8946         * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8947
8948         * insdel.c, lisp.h (buffer_overflow): New function.
8949         (insert_from_buffer_1, replace_range, replace_range_2):
8950         * insdel.c (make_gap_larger):
8951         * editfns.c (Finsert_char):
8952         * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8953
8954         * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.

8956 2011-06-15  Paul Eggert  <eggert@cs.ucla.edu>
8957
8958         Integer overflow and signedness fixes (Bug#8873, Bug#8828).
8959
8960         * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
8961         (GET_CCL_RANGE, IN_INT_RANGE): Use it.
8962
8963         * fileio.c: Don't assume EMACS_INT fits in off_t.
8964         (emacs_lseek): New static function.
8965         (Finsert_file_contents, Fwrite_region): Use it.
8966         Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
8967
8968         * fns.c (Fload_average): Don't assume 100 * load average fits in int.
8969
8970         * fns.c: Don't overflow int when computing a list length.
8971         * fns.c (QUIT_COUNT_HEURISTIC): New constant.
8972         (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
8973         truncation on 64-bit hosts.  Check for QUIT every
8974         QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
8975         faster and is responsive enough.
8976         (Flength): Report an error instead of overflowing an integer.
8977         (Fsafe_length): Return a float if the value is not representable
8978         as a fixnum.  This shouldn't happen except in contrived situations.
8979         (Fnthcdr, Fsort): Don't assume list length fits in int.
8980         (Fcopy_sequence): Don't assume vector length fits in int.
8981
8982         * alloc.c: Check that resized vectors' lengths fit in fixnums.
8983         (header_size, word_size): New constants.
8984         (allocate_vectorlike): Don't check size overflow here.
8985         (allocate_vector): Check it here instead, since this is the only
8986         caller of allocate_vectorlike that could cause overflow.
8987         Check that the new vector's length is representable as a fixnum.
8988
8989         * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
8990         The previous code was bogus.  For example, next_almost_prime (32)
8991         returned 39, which is undesirable as it is a multiple of 3; and
8992         next_almost_prime (24) returned 25, which is a multiple of 5 so
8993         why was the code bothering to check for multiples of 7?
8994
8995         * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
8996
8997         * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
8998
8999         Variadic C functions now count arguments with ptrdiff_t.
9000         This partly undoes my 2011-03-30 change, which replaced int with size_t.
9001         Back then I didn't know that the Emacs coding style prefers signed int.
9002         Also, in the meantime I found a few more instances where arguments
9003         were being counted with int, which may truncate counts on 64-bit
9004         machines, or EMACS_INT, which may be unnecessarily wide.
9005         * lisp.h (struct Lisp_Subr.function.aMANY)
9006         (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9007         Arg counts are now ptrdiff_t, not size_t.
9008         All variadic functions and their callers changed accordingly.
9009         (struct gcpro.nvars): Now size_t, not size_t.  All uses changed.
9010         * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9011         to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
9012         * callint.c (Fcall_interactively): Check arg count for overflow,
9013         to avoid potential buffer overrun.  Use signed char, not 'int',
9014         for 'varies' array, so that we needn't bother to check its size
9015         calculation for overflow.
9016         * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9017         * eval.c (apply_lambda):
9018         * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9019         (struct textprop_rec.argnum): Now ptrdiff_t, not int.  All uses changed.
9020         (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9021
9022         * callint.c (Fcall_interactively): Don't use index var as event count.
9023
9024         * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9025         * mem-limits.h (SIZE): Remove; no longer used.
9026
9027         * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9028
9029         Remove unnecessary casts.
9030         * xterm.c (x_term_init):
9031         * xfns.c (x_set_border_pixel):
9032         * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9033         These aren't needed now that we assume ANSI C.
9034
9035         * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9036         It's more likely to cause problems (due to unsigned overflow)
9037         than to cure them.
9038
9039         * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9040
9041         * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9042
9043         * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9044
9045         * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9046
9047         * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9048
9049         * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9050
9051         GLYPH_CODE_FACE returns EMACS_INT, not int.
9052         * dispextern.h (merge_faces):
9053         * xfaces.c (merge_faces):
9054         * xdisp.c (get_next_display_element, next_element_from_display_vector):
9055         Don't assume EMACS_INT fits in int.
9056
9057         * character.h (CHAR_VALID_P): Remove unused parameter.
9058         * fontset.c, lisp.h, xdisp.c: All uses changed.
9059
9060         * editfns.c (Ftranslate_region_internal): Omit redundant test.
9061
9062         * fns.c (concat): Minor tuning based on overflow analysis.
9063         This doesn't fix any bugs.  Use int to hold character, instead
9064         of constantly refetching from Emacs object.  Use XFASTINT, not
9065         XINT, for value known to be a character.  Don't bother comparing
9066         a single byte to 0400, as it's always less.
9067
9068         * floatfns.c (Fexpt):
9069         * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9070
9071         * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9072         for characters.
9073
9074         * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9075
9076         * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9077         Without this fix, on a 64-bit host (aset S 0 4294967386) would
9078         incorrectly succeed when S was a string, because 4294967386 was
9079         truncated before it was used.
9080
9081         * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9082         Otherwise, an out-of-range integer could cause undefined behavior
9083         on a 64-bit host.
9084
9085         * composite.c: Use int, not EMACS_INT, for characters.
9086         (fill_gstring_body, composition_compute_stop_pos): Use int, not
9087         EMACS_INT, for values that are known to be in character range.
9088         This doesn't fix any bugs but is the usual style inside Emacs and
9089         may generate better code on 32-bit machines.
9090
9091         Make sure a 64-bit char is never passed to ENCODE_CHAR.
9092         This is for reasons similar to the recent CHAR_STRING fix.
9093         * charset.c (Fencode_char): Check that character arg is actually
9094         a character.  Pass an int to ENCODE_CHAR.
9095         * charset.h (ENCODE_CHAR): Verify that the character argument is no
9096         wider than 'int', as a compile-time check to prevent future regressions
9097         in this area.
9098
9099         * character.c (char_string): Remove unnecessary casts.
9100
9101         Make sure a 64-bit char is never passed to CHAR_STRING.
9102         Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9103         by silently ignoring the top 32 bits, allowing some values
9104         that were far too large to be valid characters.
9105         * character.h: Include <verify.h>.
9106         (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9107         arguments are no wider than unsigned, as a compile-time check
9108         to prevent future regressions in this area.
9109         * data.c (Faset):
9110         * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9111         (Fsubst_char_in_region):
9112         * fns.c (concat):
9113         * xdisp.c (decode_mode_spec_coding):
9114         Adjust to CHAR_STRING's new requirement.
9115         * editfns.c (Finsert_char, Fsubst_char_in_region):
9116         * fns.c (concat): Check that character args are actually
9117         characters.  Without this test, these functions did the wrong
9118         thing with wildly out-of-range values on 64-bit hosts.
9119
9120         Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9121         These casts should not be needed on 32-bit hosts, either.
9122         * keyboard.c (read_char):
9123         * lread.c (Fload): Remove casts to unsigned.
9124
9125         * lisp.h (UNSIGNED_CMP): New macro.
9126         This fixes comparison bugs on 64-bit hosts.
9127         (ASCII_CHAR_P): Use it.
9128         * casefiddle.c (casify_object):
9129         * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9130         (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9131         * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9132         * dispextern.h (FACE_FROM_ID):
9133         * keyboard.c (read_char): Use UNSIGNED_CMP.
9134
9135         * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9136         not to EMACS_INT, to avoid GCC warning.
9137
9138         * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9139
9140         * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9141         The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9142         isn't needed on 32-bit machines.
9143
9144         * buffer.c (Fgenerate_new_buffer_name):
9145         Use EMACS_INT for count, not int.
9146         (advance_to_char_boundary): Return EMACS_INT, not int.
9147
9148         * data.c (Qcompiled_function): Now static.
9149
9150         * window.c (window_body_lines): Now static.
9151
9152         * image.c (gif_load): Rename local to avoid shadowing.
9153
9154         * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9155         (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9156         * alloc.c (make_save_value): Integer argument is now of type
9157         ptrdiff_t, not int.
9158         (mark_object): Use ptrdiff_t, not int.
9159         * lisp.h (pD): New macro.
9160         * print.c (print_object): Use it.
9161
9162         * alloc.c: Use EMACS_INT, not int, to count objects.
9163         (total_conses, total_markers, total_symbols, total_vector_size)
9164         (total_free_conses, total_free_markers, total_free_symbols)
9165         (total_free_floats, total_floats, total_free_intervals)
9166         (total_intervals, total_strings, total_free_strings):
9167         Now EMACS_INT, not int.  All uses changed.
9168         (Fgarbage_collect): Compute overall total using a double, so that
9169         integer overflow is less likely to be a problem.  Check for overflow
9170         when converting back to an integer.
9171         (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9172         (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9173         These were 'int' variables that could overflow on 64-bit hosts;
9174         they were never used, so remove them instead of repairing them.
9175         (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9176         (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9177         Previously, this ceilinged at INT_MAX, but that doesn't work on
9178         64-bit machines.
9179         (allocate_pseudovector): Don't use EMACS_INT when int would do.
9180
9181         * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9182         (allocate_vectorlike): Check for ptrdiff_t overflow.
9183         (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9184         when a (possibly-narrower) signed value would do just as well.
9185         We prefer using signed arithmetic, to avoid comparison confusion.
9186
9187         * alloc.c: Catch some string size overflows that we were missing.
9188         (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9189         for convenience in STRING_BYTES_MAX.
9190         (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9191         The definition here is exact; the one in lisp.h was approximate.
9192         (allocate_string_data): Check for string overflow.  This catches
9193         some instances we weren't catching before.  Also, it catches
9194         size_t overflow on (unusual) hosts where SIZE_MAX <= min
9195         (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9196         and ptrdiff_t and EMACS_INT are both 64 bits.
9197
9198         * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9199         All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9200         * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9201
9202         * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9203
9204         * alloc.c (Fmake_string): Check for out-of-range init.
9205
9206 2011-06-15  Stefan Monnier  <monnier@iro.umontreal.ca>
9207
9208         * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9209
9210 2011-06-14  Jan Djärv  <jan.h.d@swipnet.se>
9211
9212         * xfns.c (x_set_scroll_bar_default_width): Remove argument to
9213         xg_get_default_scrollbar_width.
9214
9215         * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
9216         (int_gtk_range_get_value): Move to the scroll bar part of the file.
9217         (style_changed_cb): Call update_theme_scrollbar_width and call
9218         x_set_scroll_bar_default_width and xg_frame_set_char_size for
9219         all frames (Bug#8505).
9220         (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
9221         Call gtk_window_set_resizable if HAVE_GTK3.
9222         (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9223         and height if HAVE_GTK3 (Bug#8505).
9224         (scroll_bar_width_for_theme): New variable.
9225         (update_theme_scrollbar_width): New function.
9226         (xg_get_default_scrollbar_width): Move code to
9227         update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
9228         (xg_initialize): Call update_theme_scrollbar_width.
9229
9230         * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
9231
9232         * emacsgtkfixed.c, emacsgtkfixed.h: New files.
9233
9234 2011-06-12  Martin Rudalics  <rudalics@gmx.at>
9235
9236         * frame.c (make_frame): Call other_buffer_safely instead of

9618         * editfns.c (Fformat):
9619         * eval.c (verror):
9620         Use STRING_BYTES_MAX, not MOST_POSITIVE_FIXNUM,
9621         since they may not be the same number.
9622         * editfns.c (Finsert_char):
9623         * fileio.c (Finsert_file_contents):

9651         since it makes no difference and we prefer signed.
9652         * keyboard.c (record_char): Use XUINT when all the neighbors do.
9653         (access_keymap): NATNUMP -> INTEGERP, since the integer must be
9654         nonnegative.

9766         (bidi_level_of_next_char, bidi_move_to_visually_next):
9767         Support character positions inside a run of characters covered by a
9768         display string.
9769         (bidi_paragraph_init, bidi_resolve_explicit_1)
9770         (bidi_level_of_next_char): Call bidi_fetch_char and

9776         (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
9777         instead of using explicit *_CHAR codes.
9778         (bidi_resolve_explicit, bidi_resolve_weak):
9779         Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of

9787         (bidi_level_of_next_char): Don't try to lookup the cache for the
9788         next/previous character if nothing is cached there yet, or if we

9790
9791         * xdisp.c (set_cursor_from_row): Set start and stop points
9792         according to the row's direction when priming the loop that looks

9795         (display_prop_intangible_p): Reimplement to call
9796         handle_display_spec instead of single_display_spec_intangible_p.
9797         Accept 3 additional arguments needed by handle_display_spec.
9798         This fixes incorrect cursor motion across display property with complex
9799         values: lists, `(when COND...)' forms, etc.
9800         (single_display_spec_string_p): Support property values that are
9801         lists with the argument STRING its top-level element.

9806         (compute_display_string_pos): Accept additional argument
9807         FRAME_WINDOW_P.  Call handle_display_spec to determine whether the
9808         value of a `display' property is a "replacing spec".
9809         (handle_single_display_spec): Accept 2 additional arguments BUFPOS
9810         and FRAME_WINDOW_P.  If IT is NULL, don't set up the iterator from
9811         the display property, but just return a value indicating whether
9812         the display property will replace the characters it covers.
9813         (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
9814         frame_window_p members of struct bidi_it.
9815         (compute_display_string_pos, compute_display_string_end):
9816         New functions.
9817         (push_it): Accept second argument POSITION, where pop_it should
9818         jump to continue iteration.
9819         (reseat_1): Initialize bidi_it.disp_pos.
9820
9821         * keyboard.c (adjust_point_for_property): Adjust the call to
9822         display_prop_intangible_p to its new signature.
9823
9824         * dispextern.h (struct bidi_it): New member frame_window_p.
9825         (bidi_init_it): Update prototypes.
9826         (display_prop_intangible_p): Update prototype.
9827         (compute_display_string_pos, compute_display_string_end):
9828         Declare prototypes.

9836         * lisp.h: Change signatures accordingly.
9837         * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:

9839
9840         * gnutls.c: Use Emacs's memory allocators.
9841         Without this change, the gnutls library would invoke malloc etc.
9842         directly, which causes problems on non-SYNC_INPUT hosts, and which
9843         runs afoul of improving memory_full behavior.  (Bug#8761)
9844         (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9845         (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9846         xfree instead of the default malloc, realloc, free.
9847         (Fgnutls_boot): No need to check for memory allocation failure,
9848         since xmalloc does that for us.
9849
9850         Remove arbitrary limit of 2**31 entries in hash tables.  (Bug#8771)

9879         Check for integer overflow with large hash tables.
9880         (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9881         Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9882         (SXHASH_REDUCE): New macro.
9883         (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):

9885         (sxhash_float): New function.
9886         (sxhash): Use it.  No more need for "& INTMASK" due to above changes.

9888         (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9889         Rewrite to use FIXNUM_BITS, as this simplifies things.
9890         (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9891         Adjust signatures to match updated version of code.

9893         use more than INT_MAX bytes.

9946         "initialized", do it in the caller.

10004
10005         Avoid a sign-extension bug in crypto_hash_function.
10006         * fns.c (to_uchar): Define.
10007         (crypto_hash_function): Use it to convert some newly-signed
10008         variables to unsigned, to avoid sign-extension bugs.  For example,
10009         without this change, (md5 "truc") would evaluate to
10010         45723a2aff78ff4fff7fff1114760e62 rather than the expected
10011         45723a2af3788c4ff17f8d1114760e62.  Reported by Antoine Levitt in

10015
10016         Integer overflow fixes.
10017
10018         * dbusbind.c: Serial number integer overflow fixes.
10019         (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10020         (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10021         to hold a serial number that is too large for a fixnum.
10022         (Fdbus_method_return_internal, Fdbus_method_error_internal):
10023         Check for serial numbers out of range.  Decode any serial number
10024         that was so large that it became a float.  (Bug#8722)
10025
10026         * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10027         (Fdbus_call_method, Fdbus_call_method_asynchronously):
10028         Use XFASTINT rather than XUINT when numbers are nonnegative.
10029         (xd_append_arg, Fdbus_method_return_internal):
10030         (Fdbus_method_error_internal): Likewise.  Also, for unsigned
10031         arguments, check that Lisp number is nonnegative, rather than
10032         silently wrapping negative numbers around.  (Bug#8722)
10033         (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10034         (Bug#8722)
10035
10036         * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10037
10038         * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10039
10040         ccl: Add integer overflow checks.
10041         * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10042         (IN_INT_RANGE): New macros.
10043         (ccl_driver): Use them to check for integer overflow when
10044         decoding a CCL program.  Many of the new checks are whether XINT (x)
10045         fits in int; it doesn't always, on 64-bit hosts.  The new version
10046         doesn't catch all possible integer overflows, but it's an
10047         improvement.  (Bug#8719)
10048
10049         * alloc.c (make_event_array): Use XINT, not XUINT.
10050         There's no need for unsigned here.
10051
10052         * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10053         This follows up to the 2011-05-06 change that substituted uintptr_t
10054         for EMACS_INT.  This case wasn't caught back then.
10055
10056         Rework Fformat to avoid integer overflow issues.
10057         * editfns.c: Include <float.h> unconditionally, as it's everywhere
10058         now (part of C89).  Include <verify.h>.
10059         (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10060         (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10061         (Fformat): Avoid the prepass trying to compute sizes; it was only
10062         approximate and thus did not catch overflow reliably.  Instead, walk
10063         through the format just once, formatting and computing sizes as we go,
10064         checking for integer overflow at every step, and allocating a larger
10065         buffer as needed.  Keep track separately whether the format is
10066         multibyte.  Keep only the most-recently calculated precision, rather
10067         than them all.  Record whether each argument has been converted to
10068         string.  Use EMACS_INT, not int, for byte and char and arg counts.
10069         Support field widths and precisions larger than INT_MAX.  Avoid
10070         sprintf's undefined behavior with conversion specifications such as %#d
10071         and %.0c.  Fix bug with strchr succeeding on '\0' when looking for
10072         flags.  Fix bug with (format "%c" 256.0).  Avoid integer overflow when
10073         formatting out-of-range floating point numbers with int
10074         formats.  (Bug#8668)
10075
10076         * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10077
10078         * data.c: Avoid integer truncation in expressions involving floats.
10079         * data.c: Include <intprops.h>.
10080         (arith_driver): When there's an integer overflow in an expression
10081         involving floating point, convert the integers to floating point
10082         so that the resulting value does not suffer from catastrophic
10083         integer truncation.  For example, on a 64-bit host (* 4
10084         most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10085         Do not rely on undefined behavior after integer overflow.
10086
10087         merge count_size_as_multibyte, parse_str_to_multibyte
10088         * character.c, character.h (count_size_as_multibyte):
10089         Rename from parse_str_to_multibyte; all uses changed.
10090         Check for integer overflow.
10091         * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10092         since it's now a duplicate of the other.  This is more of
10093         a character than a buffer op, so better that it's in character.c.
10094         * fns.c, print.c: Adjust to above changes.
10095
10096 2011-05-27  Stefan Monnier  <monnier@iro.umontreal.ca>
10097
10098         * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.

10105         (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10106
10107         * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.

10116

10127         (Fx_own_selection_internal, Fx_get_selection_internal)

10130         (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10131         (x_handle_selection_clear): Don't treat other terminals with the
10132         same keyboard specially.  Use the terminal-local Vselection_alist.
10133         (x_clear_frame_selections): Use Frun_hook_with_args.
10134
10135         * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10136
10137         * xterm.h: Add support for those atoms.
10138

10144         (x_get_local_selection): Remove unnecessary code.
10145         (x_reply_selection_request): Args changed; handle arbitrary array
10146         of converted selections stored in converted_selections.
10147         Separate the XChangeProperty and SelectionNotify steps.
10148         (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10149         (x_convert_selection): New function.
10150         (x_handle_selection_event): Simplify.
10151         (x_get_foreign_selection): Don't ignore incoming requests while
10152         waiting for an answer; this will fail when we implement
10153         SAVE_TARGETS, and seems unnecessary anyway.
10154         (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10155         (Vx_sent_selection_functions): Doc fix.

10173         row.  Mark glyph row for fringe update if periodicity changed.
10174
10175         * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10176         for fringe update unless it has periodic bitmap.

10178 2011-05-25  Kenichi Handa  <handa@m17n.org>
10179
10180         * xdisp.c (get_next_display_element): Set correct it->face_id for
10181         a static composition.
10182
10183 2011-05-24  Leo Liu  <sdl.web@gmail.com>
10184
10185         * deps.mk (fns.o):
10186         * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10187
10188         * fns.c (crypto_hash_function, Fsha1): New function.
10189         (Fmd5): Use crypto_hash_function.
10190         (syms_of_fns): Add Ssha1.
10191
10192 2011-05-22  Paul Eggert  <eggert@cs.ucla.edu>
10193
10194         * gnutls.c: Remove unused macros.
10195         (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10196         (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10197         Remove macros that are defined and never used.
10198         Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10199
10200 2011-05-22  Chong Yidong  <cyd@stupidchicken.com>
10201
10202         * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10203         (Fx_get_selection_internal): Minor cleanup.
10204         (Fx_own_selection_internal): Rename arguments for consistency with
10205         select.el.
10206
10207 2011-05-22  Paul Eggert  <eggert@cs.ucla.edu>
10208
10209         * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10210
10211 2011-05-22  Chong Yidong  <cyd@stupidchicken.com>
10212
10213         * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10214
10215 2011-05-21  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>
10216
10217         * dispnew.c (scrolling_window): Don't exclude the case that the
10218         last enabled row in the desired matrix touches the bottom boundary.
10219
10220 2011-05-21  Glenn Morris  <rgm@gnu.org>
10221
10222         * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10223         (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10224         and add some more files.
10225
10226 2011-05-20  Eli Zaretskii  <eliz@gnu.org>
10227
10228         * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10229         report_file_error introduced by the change from 2011-05-07.
10230
10231 2011-05-20  Paul Eggert  <eggert@cs.ucla.edu>
10232
10233         * systime.h (Time): Define only if emacs is defined.
10234         This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10235         where the include path doesn't have X11/X.h by default.  See
10236         <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

10238 2011-05-20  Kenichi Handa  <handa@m17n.org>
10239
10240         * composite.c (find_automatic_composition): Fix previous change.
10241
10242 2011-05-20  Glenn Morris  <rgm@gnu.org>
10243
10244         * lisp.mk: New file, split from Makefile.in.
10245         * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10246         (shortlisp): Remove.
10247         ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10248
10249 2011-05-19  Glenn Morris  <rgm@gnu.org>
10250
10251         * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10252         (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10253         (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10254         (lisp): Set the order to that of loadup.el.
10255         (shortlisp): Make it a copy of $lisp.
10256         (SOME_MACHINE_LISP): Remove.
10257         ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10258         Use just $shortlisp, not $SOME_MACHINE_LISP too.
10259
10260 2011-05-18  Kenichi Handa  <handa@m17n.org>
10261
10262         * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10263         (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10264         (find_automatic_composition): Mostly rewrite for efficiency.
10265
10266 2011-05-18  Juanma Barranquero  <lekktu@gmail.com>
10267
10268         * makefile.w32-in: Update dependencies.

10270 2011-05-18  Christoph Scholtes  <cschol2112@googlemail.com>
10271
10272         * menu.c: Include limits.h (fixes the MS-Windows build broken by
10273         2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10274
10275 2011-05-18  Paul Eggert  <eggert@cs.ucla.edu>
10276
10277         Fix some integer overflow issues, such as string length overflow.
10278
10279         * insdel.c (count_size_as_multibyte): Check for string overflow.
10280
10281         * character.c (lisp_string_width): Check for string overflow.
10282         Use EMACS_INT, not int, for string indexes and lengths; in
10283         particular, 2nd arg is now EMACS_INT, not int.  Do not crash if
10284         the resulting string length overflows an EMACS_INT; instead,
10285         report a string overflow if no precision given.  When checking for
10286         precision exhaustion, use a check that cannot possibly have
10287         integer overflow.  (Bug#8675)
10288         * character.h (lisp_string_width): Adjust to new signature.
10289
10290         * alloc.c (string_overflow): New function.
10291         (Fmake_string): Use it.  This doesn't change behavior, but saves
10292         a few bytes and will simplify future changes.
10293         * character.c (string_escape_byte8): Likewise.
10294         * lisp.h (string_overflow): New decl.
10295
10296         Fixups, following up to the user-interface timestamp change.
10297         * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10298         for UI timestamps, instead of unsigned long.
10299         * msdos.c (mouse_get_pos): Likewise.
10300         * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10301         * w32gui.h (Time): Define by including "systime.h" rather than by
10302         declaring it ourselves.  (Bug#8664)
10303
10304         * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10305         * image.c (clear_image_cache): Likewise.
10306
10307         * term.c (term_mouse_position): Don't assume time_t wraparound.
10308
10309         Be more systematic about user-interface timestamps.
10310         Before, the code sometimes used 'Time', sometimes 'unsigned long',
10311         and sometimes 'EMACS_UINT', to represent these timestamps.
10312         This change causes it to use 'Time' uniformly, as that's what X uses.
10313         This makes the code easier to follow, and makes it easier to catch
10314         integer overflow bugs such as Bug#8664.
10315         * frame.c (Fmouse_position, Fmouse_pixel_position):
10316         Use Time, not unsigned long, for user-interface timestamps.
10317         * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10318         (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10319         * keyboard.h (last_event_timestamp): Likewise.
10320         * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10321         * menu.h (xmenu_show): Likewise.
10322         * term.c (term_mouse_position): Likewise.
10323         * termhooks.h (struct input_event.timestamp): Likewise.
10324         (struct terminal.mouse_position_hook): Likewise.
10325         * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10326         * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10327         * systime.h (Time): New decl.  Pull it in from <X11/X.h> if
10328         HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10329         what it was before.
10330         * menu.h, termhooks.h: Include "systime.h", for Time.
10331
10332         * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10333         Don't assume that the difference between two unsigned long values
10334         can fit into an integer.  At this point, we know button_down_time
10335         <= event->timestamp, so the difference must be nonnegative, so
10336         there's no need to cast the result if double-click-time is
10337         nonnegative, as it should be; check that it's nonnegative, just in
10338         case.  This bug is triggered when events are more than 2**31 ms
10339         apart (about 25 days).  (Bug#8664)
10340
10341         * xselect.c (last_event_timestamp): Remove duplicate decl.
10342         (x_own_selection): Remove needless cast to unsigned long.
10343
10344         * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10345         that always fit in int.  Use a sentinel instead of a counter, to
10346         avoid a temp and to allay GCC's concerns about possible int overflow.
10347         * frame.h (struct frame): Use int for menu_bar_items_used
10348         instead of EMACS_INT, since it always fits in int.
10349
10350         * menu.c (grow_menu_items): Check for int overflow.
10351
10352         * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10353
10354         * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10355         Before, the code was not consistent.  These values cannot exceed
10356         2**31 - 1 so there's no need to make them unsigned.
10357         (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10358         (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10359         (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10360         as modifiers.
10361         * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10362
10363         * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10364         (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10365         Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10366         presumably because the widths might not match.
10367
10368         * window.c (size_window): Avoid needless test at loop start.
10369
10370 2011-05-18  Courtney Bane  <emacs-bugs-7626@cbane.org>  (tiny change)
10371
10372         * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10373
10374 2011-05-12  Drew Adams  <drew.adams@oracle.com>
10375
10376         * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10377
10378 2011-05-12  YAMAMOTO Mitsuharu  <mituharu@math.s.chiba-u.ac.jp>
10379
10380         * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10381         `width' to `bar_area_x' and `bar_area_width', respectively.
10382         (x_scroll_run): Take account of fringe background extension.
10383
10384         * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10385         Rename local vars `left' and `width' to `bar_area_x' and
10386         `bar_area_width', respectively.
10387         (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10388         background extension.
10389
10390 2011-05-10  Jim Meyering  <meyering@redhat.com>
10391
10392         * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10393
10394 2011-05-10  Juanma Barranquero  <lekktu@gmail.com>
10395
10396         * image.c (Finit_image_library): Return t for built-in image types,
10397         like pbm and xbm.  (Bug#8640)
10398
10399 2011-05-09  Andreas Schwab  <schwab@linux-m68k.org>
10400
10401         * w32menu.c (set_frame_menubar): Fix submenu allocation.
10402
10403 2011-05-07  Eli Zaretskii  <eliz@gnu.org>
10404
10405         * w32console.c (Fset_screen_color): Doc fix.
10406         (Fget_screen_color): New function.
10407         (syms_of_ntterm): Defsubr it.
10408
10409         * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10410         unlink the temporary file if Fcall_process didn't create it in the
10411         first place.
10412         (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10413         child process will be redirected to a file specified with `:file'.
10414         Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10415         cue to call_process_cleanup not to close that handle.
10416
10417 2011-05-07  Ben Key  <bkey76@gmail.com>
10418
10419         * makefile.w32-in: The bootstrap-temacs rule now makes use of
10420         one of two shell specific rules, either bootstrap-temacs-CMD or
10421         bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
10422         to the previous implementation of the bootstrap-temacs rule.
10423         The bootstrap-temacs-CMD rule is similar to the previous
10424         implementation of the bootstrap-temacs rule except that it
10425         makes use of the ESC_CFLAGS variable instead of the CFLAGS
10426         variable.
10427
10428         These changes, along with some changes to nt/configure.bat,
10429         nt/gmake.defs, and nt/nmake.defs, are required to extend my
10430         earlier fix to add support for --cflags and --ldflags options
10431         that include quotes so that it works whether make uses cmd or
10432         sh as the shell.
10433
10434 2011-05-06  Michael Albinus  <michael.albinus@gmx.de>
10435
10436         * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10437         (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10438         is a constant.
10439         (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10440         a string.  Handle both cases.
10441         (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10442         (Fdbus_register_method): Use Qinvalid_function.
10443
10444 2011-05-06  Juanma Barranquero  <lekktu@gmail.com>
10445
10446         * makefile.w32-in: Update dependencies.
10447         (LISP_H): Add inttypes.h and stdin.h.
10448         (PROCESS_H): Add unistd.h.
10449
10450 2011-05-06  Eli Zaretskii  <eliz@gnu.org>
10451
10452         * lread.c: Include limits.h (fixes the MS-Windows build broken by
10453         2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10454
10455 2011-05-06  Paul Eggert  <eggert@cs.ucla.edu>
10456
10457         * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10458
10459         * term.c (vfatal): Remove stray call to va_end.
10460         It's not needed and the C Standard doesn't allow it here anyway.
10461
10462         Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10463         * eval.c (verror): doprnt a copy of ap, not the original.  (Bug#8545)
10464
10465         * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10466         bytes.
10467
10468         * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10469
10470         * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10471
10472         * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10473
10474         * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10475
10476         * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10477
10478         * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10479         * charset.c (Fdefine_charset_internal): Don't initialize
10480         charset.code_space[15].  The value was garbage, on hosts with
10481         32-bit int (Bug#8600).
10482
10483         * lread.c (read_integer): Be more consistent with string-to-number.
10484         Use string_to_number to do the actual conversion; this avoids
10485         rounding errors and fixes some other screwups.  Without this fix,
10486         for example, #x1fffffffffffffff was misread as -2305843009213693952.
10487         (digit_to_number): Move earlier, for benefit of read_integer.
10488         Return -1 if the digit is out of range for the base, -2 if it is
10489         not a digit in any supported base.  (Bug#8602)
10490
10491         * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10492
10493         * dispnew.c (scrolling_window): Return 1 if we scrolled,
10494         to match comment at start of function.  This also removes a
10495         GCC warning about overflow in a 32+64-bit port.
10496
10497         * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10498
10499         * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10500         Reported by Stefan Monnier in
10501         <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10502         (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10503         Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10504
10505         * lisp.h (EMACS_INTPTR): Remove.  All uses changed to intptr_t.
10506         (EMACS_UINTPTR): Likewise, with uintptr_t.
10507
10508         * lisp.h: Prefer 64-bit EMACS_INT if available.
10509         (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10510         on 32-bit hosts that have 64-bit int, so that they can access
10511         large files.
10512         However, temporarily disable this change unless the temporary
10513         symbol WIDE_EMACS_INT is defined.
10514
10515         * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10516
10517         Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10518         This removes an assumption that EMACS_INT and long are the same
10519         width as pointers.  The assumption is true for Emacs porting targets
10520         now, but we want to make other targets possible.
10521         * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10522         (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10523         In the rest of the code, change types of integers that hold casted
10524         pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10525         replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10526         (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10527         (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10528         No need to cast type when ORing.
10529         (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10530         * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10531         * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10532         assume EMACS_INT is the same width as char *.
10533         * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10534         (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10535         Remove no-longer-needed casts.
10536         (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10537         (xg_tool_bar_help_callback, xg_make_tool_item):
10538         Use EMACS_INTPTR to hold an integer
10539         that will be cast to void *; this can avoid a GCC warning
10540         if EMACS_INT is not the same width as void *.
10541         * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10542         * xdisp.c (display_echo_area_1, resize_mini_window_1):
10543         (current_message_1, set_message_1):
10544         Use a local to convert to proper width without a cast.
10545         * xmenu.c (dialog_selection_callback): Likewise.
10546
10547         * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10548         Also, don't assume VALBITS / RAND_BITS is less than 5,
10549         and don't rely on undefined behavior when shifting a 1 left into
10550         the sign bit.
10551         * lisp.h (get_random): Change signature to match.
10552
10553         * lread.c (hash_string): Use size_t, not int, for hash computation.
10554         Normally we prefer signed values; but hashing is special, because
10555         it's better to use unsigned division on hash table sizes so that
10556         the remainder is nonnegative.  Also, size_t is the natural width
10557         for hashing into memory.  The previous code used 'int', which doesn't
10558         retain enough info to hash well into very large tables.
10559         (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10560
10561         * dbusbind.c: Don't possibly lose pointer info when converting.
10562         (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10563         Use XPNTR rather than XHASH, so that the high-order bits of
10564         the pointer aren't lost when converting through void *.
10565
10566         * eval.c (Fautoload): Don't double-shift a pointer.
10567
10568         * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10569
10570 2011-05-06  Juanma Barranquero  <lekktu@gmail.com>
10571
10572         * gnutls.c (DEF_GNUTLS_FN):
10573         * image.c (DEF_IMGLIB_FN): Make function pointers static.
10574
10575 2011-05-05  Andreas Schwab  <schwab@linux-m68k.org>
10576
10577         * lread.c (lisp_file_lexically_bound_p): Stop scanning at end

10579
10580 2011-05-05  Eli Zaretskii  <eliz@gnu.org>

10583         New version that can reserve upto 2GB of heap space.
10584
10585 2011-05-05  Chong Yidong  <cyd@stupidchicken.com>
10586
10587         * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

10589 2011-05-05  Teodor Zlatanov  <tzz@lifelogs.com>
10590
10591         * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
10592         `gnutls_certificate_set_x509_key_file'.
10593

10595

10787
10788         * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10789         change.

10792
10793         * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10794         This makes this file independent of the recent pseudovector change.

10797
10798         * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10799
10800         * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10801         (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10802         Remove unused local.
10803         (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10804
10805         * lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
10806         GCC 4.6.0 optimizes based on type-based alias analysis.
10807         For example, if b is of type struct buffer * and v of type struct
10808         Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10809         != &v->size, and therefore "v->size = 1; b->size = 2; return
10810         v->size;" must therefore return 1.  This assumption is incorrect
10811         for Emacs, since it type-puns struct Lisp_Vector * with many other
10812         types.  To fix this problem, this patch adds a new type struct
10813         vectorlike_header that documents the constraints on layout of vectors
10814         and pseudovectors, and helps optimizing compilers not get fooled
10815         by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
10816         XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10817         * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10818         the size member.
10819         (XSETPVECTYPE): Rewrite in terms of new macro.
10820         (XSETPVECTYPESIZE): New macro, specifying both type and size.
10821         This is a bit clearer, and further avoids the possibility of
10822         undesirable aliasing.
10823         (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10824         (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10825         (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10826         since Lisp_Subr is a special case (no "next" field).
10827         (ASIZE): Now uses header.size rather than size.
10828         All previous uses of XVECTOR (foo)->size replaced to use this macro,
10829         to avoid the hassle of writing XVECTOR (foo)->header.size.
10830         (struct vectorlike_header): New type.
10831         (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10832         object, to help avoid aliasing.
10833         (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10834         (SUBRP): Likewise, since Lisp_Subr is a special case.
10835         * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10836         (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10837         (struct Lisp_Hash_Table): Combine first two members into a single
10838         struct vectorlike_header member.  All uses of "size" and "next" members
10839         changed to be "header.size" and "header.next".
10840         * buffer.h (struct buffer): Likewise.
10841         * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10842         * frame.h (struct frame): Likewise.
10843         * process.h (struct Lisp_Process): Likewise.
10844         * termhooks.h (struct terminal): Likewise.
10845         * window.c (struct save_window_data, struct saved_window): Likewise.
10846         * window.h (struct window): Likewise.
10847         * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10848         Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10849         * buffer.c (init_buffer_once): Likewise.
10850         * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10851         special case.
10852         * process.c (Fformat_network_address): Use local var for size,
10853         for brevity.
10854
10855         * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10856
10857         Make the Lisp reader and string-to-float more consistent (Bug#8525)
10858         * data.c (atof): Remove decl; no longer used or needed.
10859         (digit_to_number): Move to lread.c.
10860         (Fstring_to_number): Use new string_to_number function, to be
10861         consistent with how the Lisp reader treats infinities and NaNs.
10862         Do not assume that floating-point numbers represent EMACS_INT
10863         without losing information; this is not true on most 64-bit hosts.
10864         Avoid double-rounding errors, by insisting on integers when
10865         parsing non-base-10 numbers, as the documentation specifies.
10866         * lisp.h (string_to_number): New decl, replacing ...
10867         (isfloat_string): Remove.
10868         * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10869         (read1): Do not accept +. and -. as integers; this
10870         appears to have been a coding error.  Similarly, do not accept
10871         strings like +-1e0 as floating point numbers.  Do not report
10872         overflow for integer overflows unless the base is not 10 which
10873         means we have no simple and reliable way to continue.
10874         Break out the floating-point parsing into a new
10875         function string_to_number, so that Fstring_to_number parses
10876         floating point numbers consistently with the Lisp reader.
10877         (digit_to_number): Move here from data.c.  Make it static inline.
10878         (E_CHAR, EXP_INT): Remove, replacing with ...
10879         (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10880         (string_to_number): New function, replacing isfloat_string.
10881         This function checks for valid syntax and produces the resulting
10882         Lisp float number too.  Rework it so that string-to-number
10883         no longer mishandles examples like "1.0e+".  Use strtoumax,
10884         so that overflow for non-base-10 numbers is reported only when
10885         there's no portable and simple way to convert to floating point.
10886
10887         * textprop.c (set_text_properties_1): Rewrite for clarity,
10888         and to avoid GCC warning about integer overflow.
10889
10890         * intervals.h (struct interval): Use EMACS_INT for members
10891         where EMACS_UINT might cause problems.  See
10892         <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10893         (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10894         * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10895         All uses changed.
10896         (offset_intervals): Tell GCC not to worry about length overflow
10897         when negating a negative length.
10898
10899         * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10900         (overrun_check_free): Likewise.
10901
10902         * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10903         in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10904         word size.
10905
10906         * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10907         (gnutls_make_error): Rename local to avoid shadowing.
10908         (gnutls_emacs_global_deinit): ifdef out; not used.
10909         (Fgnutls_boot): Use const for pointer to readonly storage.
10910         Comment out unused local.  Fix pointer signedness problems.
10911
10912         * lread.c (openp): Don't stuff size_t into an 'int'.
10913         Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10914         about possible signed overflow.
10915
10916         * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10917         (GDK_KEY_g): Don't define if already defined.
10918         (xg_prepare_tooltip): Avoid pointer signedness problem.
10919         (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10920
10921         * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10922         behavior with 1 << 31.  GCC 4.6.0 warns about this on 32-bit hosts.
10923
10924         * xfns.c (Fx_window_property): Simplify a bit,
10925         to make a bit faster and to avoid GCC 4.6.0 warning.
10926         * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10927
10928         * fns.c (internal_equal): Don't assume size_t fits in int.
10929
10930         * alloc.c (compact_small_strings): Tighten assertion a little.
10931
10932         Replace pEd with more-general pI, and fix some printf arg casts.
10933         * lisp.h (pI): New macro, generalizing old pEd macro to other
10934         conversion specifiers.  For example, use "...%"pI"d..." rather
10935         than "...%"pEd"...".
10936         (pEd): Remove.  All uses replaced with similar uses of pI.
10937         * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10938         * alloc.c (check_pure_size): Don't overflow by converting size to int.
10939         * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10940         * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10941         * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10942         (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10943         * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10944         64-bit hosts.
10945         (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10946         * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10947         * print.c (safe_debug_print, print_object): Likewise.
10948         (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10949         to int.
10950         Use pI instead of if-then-else-abort.  Use %p to avoid casts,
10951         avoiding the 0 flag, which is not portable.
10952         * process.c (Fmake_network_process): Use pI to avoid cast.
10953         * region-cache.c (pp_cache): Likewise.
10954         * xdisp.c (decode_mode_spec): Likewise.
10955         * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
10956         behavior on 64-bit hosts with printf arg.
10957         * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
10958         (x_stop_queuing_selection_requests): Likewise.
10959         (x_get_window_property): Don't truncate byte count to an 'int'
10960         when tracing.
10961
10962         * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
10963         here, since it parses constructs like leading '-' and spaces,
10964         which are not wanted; and it overflows with large numbers.
10965         Instead, simply match F[0-9]+, which is what is wanted anyway.
10966
10967         * alloc.c: Remove unportable assumptions about struct layout.
10968         (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
10969         (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
10970         (allocate_vectorlike, make_pure_vector): Use the new macros,
10971         plus offsetof, to remove unportable assumptions about struct layout.
10972         These assumptions hold on all porting targets that I know of, but
10973         they are not guaranteed, they're easy to remove, and removing them
10974         makes further changes easier.
10975
10976         * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
10977         This doesn't fix a bug but makes the code clearer.
10978         (string_overrun_cookie): Now const.  Use initializers that
10979         don't formally overflow signed char, to avoid warnings.
10980         (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
10981         can cause Emacs to crash when string overrun checking is enabled.
10982         (allocate_buffer): Don't assume sizeof (struct buffer) is a
10983         multiple of sizeof (EMACS_INT); it need not be, if
10984         alignof(EMACS_INT) < sizeof (EMACS_INT).
10985         (check_sblock, check_string_bytes, check_string_free_list): Protoize.

10987 2011-04-26  Juanma Barranquero  <lekktu@gmail.com>
10988
10989         * keyboard.c (QCrtl): Rename from Qrtl.  All uses changed.
10990
10991 2011-04-26  Teodor Zlatanov  <tzz@lifelogs.com>
10992
10993         * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
10994         supposed to be handshaking.  (Bug#8556)
10995         Reported by Paul Eggert <eggert@cs.ucla.edu>.
10996
10997 2011-04-26  Daniel Colascione  <dan.colascione@gmail.com>
10998
10999         * lisp.h (Qdebug): List symbol.
11000         * eval.c (Qdebug): Restore global linkage.
11001         * keyboard.c (debug-on-event): New variable.
11002         (handle_user_signal): Break into debugger when debug-on-event
11003         matches the current signal symbol.
11004
11005 2011-04-25  Dan Nicolaescu  <dann@ics.uci.edu>
11006
11007         * alloc.c (check_sblock, check_string_bytes)
11008         (check_string_free_list): Convert to standard C.
11009
11010 2011-04-25  Teodor Zlatanov  <tzz@lifelogs.com>
11011
11012         * w32.c (emacs_gnutls_push): Fix typo.
11013
11014 2011-04-25  Eli Zaretskii  <eliz@gnu.org>
11015
11016         * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11017         "cast to pointer from integer of different size".
11018
11019         Improve doprnt and its use in verror.  (Bug#8545)
11020         * doprnt.c (doprnt): Document the set of format control sequences
11021         supported by the function.  Use SAFE_ALLOCA instead of always
11022         using `alloca'.
11023
11024         * eval.c (verror): Don't limit the buffer size at size_max-1, that
11025         is one byte too soon.  Don't use xrealloc; instead xfree and
11026         xmalloc anew.
11027
11028 2011-04-24  Teodor Zlatanov  <tzz@lifelogs.com>
11029
11030         * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11031         callbacks stage.
11032
11033         * gnutls.c: Renamed global_initialized to
11034         gnutls_global_initialized.  Added internals for the
11035         :verify-hostname-error, :verify-error, and :verify-flags
11036         parameters of `gnutls-boot' and documented those parameters in the
11037         docstring.  Start callback support.
11038         (emacs_gnutls_handshake): Add Woe32 support.  Retry handshake
11039         unless a fatal error occurred.  Call gnutls_alert_send_appropriate
11040         on error.  Return error code.
11041         (emacs_gnutls_write): Call emacs_gnutls_handle_error.
11042         (emacs_gnutls_read): Likewise.
11043         (Fgnutls_boot): Return handshake error code.
11044         (emacs_gnutls_handle_error): New function.
11045         (wsaerror_to_errno): Likewise.
11046
11047         * w32.h (emacs_gnutls_pull): Add prototype.
11048         (emacs_gnutls_push): Likewise.
11049
11050         * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
11051         (emacs_gnutls_push): Likewise.
11052
11053 2011-04-24  Claudio Bley  <claudio.bley@gmail.com>  (tiny change)
11054
11055         * process.c (wait_reading_process_output): Check if GnuTLS
11056         buffered some data internally if no FDs are set for TLS
11057         connections.
11058
11059         * makefile.w32-in (OBJ2): Add gnutls.$(O).
11060         (LIBS): Link to USER_LIBS.
11061         ($(BLD)/gnutls.$(0)): New target.
11062
11063 2011-04-24  Eli Zaretskii  <eliz@gnu.org>
11064
11065         * xdisp.c (handle_single_display_spec): Rename the
11066         display_replaced_before_p argument into display_replaced_p, to
11067         make it consistent with the commentary.  Fix typos in the
11068         commentary.
11069
11070         * textprop.c (syms_of_textprop): Remove dead code.
11071         (copy_text_properties): Delete obsolete commentary about an
11072         interface that was deleted long ago.  Fix typos in the description
11073         of arguments.
11074
11075         * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list

11141
11142         * character.c (char_string): Use %x to display the (unsigned)
11143         codepoint of an invalid character, to avoid displaying a bogus
11144         negative value.
11145
11146         * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to

11224
11225         * dispextern.h (struct redisplay_interface): Rename param

11343
11344         * nsfont.m: Fixed bugs in ns_get_family and
11345         ns_descriptor_to_entity that were caused by using free to
11346         deallocate memory blocks that were allocated by xmalloc (via
11347         xstrdup).  This caused Emacs to crash when compiled with
11348         XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
11349         --enable-checking=xmallocoverrun).  xfree is now used to
11350         deallocate these memory blocks.

11695         * category.h: ... from here.
11696         * category.c (check_category_table, set_category_set): Now static.
11697
11698         * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
11699         * lisp.h: Remove these decls.
11700
11701         * buffer.c (buffer_count): Remove unused var.
11702
11703         * bidi.c (bidi_dump_cached_states): Mark as externally visible,
11704         so that it's not optimized away.
11705         (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
11706         * dispextern.h (bidi_dump_cached_states): Remove, since it's
11707         exported only to the debugger.
11708
11709         * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
11710         * atimer.h (run_all_atimers): Remove; not exported.
11711
11712         font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
11713         * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
11714         was inaccessible from Lisp.
11715         (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
11716         * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
11717
11718         alloc.c: Import and export fewer symbols, and remove unused items.
11719         * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
11720         is defined.
11721         (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
11722         it's not optimized away by whole-program optimization.
11723         (message_enable_multibyte, free_misc): Remove.
11724         (catchlist, handlerlist, mark_backtrace):
11725         Declare only if BYTE_MARK_STACK.
11726         (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
11727         * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
11728         (message_enable_multibyte): Remove decl.
11729         (free_misc, interval_free_list, float_block, float_block_index):
11730         (n_float_blocks, float_free_list, cons_block, cons_block_index):
11731         (cons_free_list, last_marked_index):
11732         Now static.
11733         (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
11734         * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
11735         (mark_backtrace): Define only if BYTE_MARK_STACK.
11736         * xdisp.c (message_enable_multibyte): Now static.
11737
11738         Declare Lisp_Object Q* variables to be 'static' if not exported.
11739         This makes it easier for human readers (and static analyzers)
11740         to see whether these variables are used from other modules.
11741         * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

11750         * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:

11753
11754         * lisp.h (DEFINE_FUNC): Make sname 'static'.
11755
11756         Make Emacs functions such as Fatom 'static' by default.
11757         This makes it easier for human readers (and static analyzers)
11758         to see whether these functions can be called from other modules.
11759         DEFUN now defines a static function.  To make the function external
11760         so that it can be used in other C modules, use the new macro DEFUE.

11765         (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
11766         Remove decls, since these functions are now static.
11767         (Funintern, Fget_internal_run_time): New decls, since these functions
11768         were already external.
11769

11778         Mark functions with DEFUE instead of DEFUN,
11779         if they are used in other modules.
11780         * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
11781         decls for now-static functions.

11837
11838         * sysdep.c (emacs_read, emacs_write): Check for negative sizes
11839         since callers should never pass a negative size.
11840         Change the signature to match that of plain 'read' and 'write'; see
11841         <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
11842         * lisp.h: Update prototypes of emacs_write and emacs_read.

11845
11846         * xdisp.c (redisplay_window): Don't try to determine the character

11848         is outside the buffer's accessible region.  (Bug#8468)
11849
11850 2011-04-10  Eli Zaretskii  <eliz@gnu.org>
11851
11852         Fix write-region and its subroutines for buffers > 2GB.
11853         * fileio.c (a_write, e_write): Modify declaration of arguments and
11854         local variables to support buffers larger than 2GB.
11855         (Fcopy_file): Use EMACS_INT for return value of emacs_read.
11856
11857         * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
11858         argument, local variables, and return value.
11859
11860         * lisp.h: Update prototypes of emacs_write and emacs_read.
11861
11862         * sound.c (vox_write): Use ssize_t for return value of emacs_write.
11863
11864 2011-04-10  Paul Eggert  <eggert@cs.ucla.edu>
11865
11866         * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
11867
11868         Fix more problems found by GCC 4.6.0's static checks.
11869
11870         * xdisp.c (vmessage): Use a better test for character truncation.
11871
11872         * charset.c (load_charset_map): <, not <=, for optimization,
11873         and to avoid potential problems with integer overflow.
11874         * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11875         * casetab.c (set_identity, shuffle): Likewise.
11876         * editfns.c (Fformat): Likewise.
11877         * syntax.c (skip_chars): Likewise.
11878
11879         * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11880         This also lets GCC 4.6.0 generate slightly better loop code.
11881
11882         * callint.c (Fcall_interactively): <, not <=, for optimization.
11883         (Fcall_interactively): Count the number of arguments produced,
11884         not the number of arguments given.  This is simpler and lets GCC
11885         4.6.0 generate slightly better code.
11886
11887         * ftfont.c: Distingish more carefully between FcChar8 and char.
11888         The previous code passed unsigned char * to a functions like
11889         strlen and xstrcasecmp that expect char *, which does not
11890         conform to the C standard.
11891         (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11892         arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11893         char * when the C standard requires it.
11894
11895         * keyboard.c (read_char): Remove unused var.
11896
11897         * eval.c: Port to Windows vsnprintf (Bug#8435).
11898         Include <limits.h>.
11899         (SIZE_MAX): Define if the headers do not.
11900         (verror): Do not give up if vsnprintf returns a negative count.
11901         Instead, grow the buffer.  This ports to Windows vsnprintf, which
11902         does not conform to C99.  Problem reported by Eli Zaretskii.
11903         Also, simplify the allocation scheme, by avoiding the need for
11904         calling realloc, and removing the ALLOCATED variable.
11905
11906         * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11907
11908         Remove invocations of doprnt, as Emacs now uses vsnprintf.
11909         But keep the doprint source code for now, as we might revamp it
11910         and use it again (Bug#8435).
11911         * lisp.h (doprnt): Remove.
11912         * Makefile.in (base_obj): Remove doprnt.o.
11913         * deps.mk (doprnt.o): Remove.
11914
11915         error: Print 32- and 64-bit integers portably (Bug#8435).
11916         Without this change, on typical 64-bit hosts error ("...%d...", N)
11917         was used to print both 32- and 64-bit integers N, which relied on
11918         undefined behavior.
11919         * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11920         * lisp.h (error, verror): Mark as printf-like functions.
11921         * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11922         Report overflow in size calculations when allocating printf buffer.
11923         Do not truncate output string at its first null byte.
11924         * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11925         Truncate the output at a character boundary, since vsnprintf does not
11926         do that.
11927         * charset.c (check_iso_charset_parameter): Convert internal
11928         character to string before calling 'error', since %c now has the
11929         printf meaning.
11930         * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11931         overflow when computing char to be passed to 'error'.  Do not
11932         pass Lisp_Object to 'error'; pass the integer instead.
11933         * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11934         formatted with plain %d.
11935
11936         * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11937
11938         * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
11939
11940         * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
11941
11942         * xterm.c (x_catch_errors): Remove duplicate declaration.
11943
11944         * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
11945
11946         * xdisp.c, lisp.h (message_nolog): Remove; unused.
11947

11949
11950         use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11951         * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11952         return ssize_t not "int", and use size_t as the buffer length.
11953         (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11954         * gnutls.h: Update declarations.
11955         * process.c (read_process_output): Use ssize_t, to match.
11956         (send_process): Likewise.

11963
11964         * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
11965         Use unsigned char, to match FcChar8 type definition.
11966
11967         * xterm.c (handle_one_xevent):
11968         * xmenu.c (create_and_show_popup_menu):

11973
11974         Fix some uses of `int' instead of EMACS_INT.
11975         * search.c (string_match_1, fast_string_match)
11976         (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
11977         (scan_buffer, find_next_newline_no_quit)
11978         (find_before_next_newline, search_command, Freplace_match)
11979         (Fmatch_data): Make some `int' variables be EMACS_INT.
11980
11981         * xdisp.c (display_count_lines): 3rd argument and return value now
11982         EMACS_INT.  All callers changed.
11983         (pint2hrstr): Last argument is now EMACS_INT.

12069
12070         * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.

12072         (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12073         directly, rather than having caller test rule sign.  This avoids
12074         some unnecessary tests.
12075         * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12076         (COMPOSITION_ENCODE_RULE): Arguments now must be valid.  This

12092
12093         * textprop.c (set_text_properties_1): Change while to do-while,

12117
12118         * font.c (font_list_entities): Redo for clarity,
12119         so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12120
12121         * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.

12128
12129         * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12130         Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12131         can always succeed if overflow has undefined behavior.
12132
12133         * search.c (boyer_moore, wordify): Remove vars set but not used.
12134         (wordify): Omit three unnecessary tests.

12152         but not used.

12155         Remove vars that are set but not used.
12156         (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12157         (timer_check_2): Mark vars as initialized.
12158

12177         Remove var that is set but not used.
12178         (scroll_bar_windows_size): Now size_t, not int.

12184
12185         * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12186
12187         * coding.c: Remove vars that are set but not used.
12188         (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12189         All callers changed.
12190         (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

12198
12199         Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12200         The gnulib version avoids calling malloc in the usual case,
12201         and on 64-bit hosts doesn't have some arbitrary 32-bit limits.

12229         and thereabouts.  All callers changed.
12230         (get_per_char_metric): Remove parameter `f', unused since
12231         2008-05-14T01:40:23Z!handa@m17n.org.  All callers changed.

12310 2011-03-31  Eli Zaretskii  <eliz@gnu.org>
12311
12312         * xdisp.c (SCROLL_LIMIT): New macro.
12313         (try_scrolling): Use it when setting scroll_limit.
12314         Limit scrolling to 100 screen lines.
12315         (redisplay_window): Even when falling back on "recentering",
12316         position point in the window according to scroll-conservatively,
12317         scroll-margin, and scroll-*-aggressively variables.  (Bug#6671)
12318
12319         (try_scrolling): When point is above the window, allow searching
12320         as far as scroll_max, or one screenful, to compute vertical
12321         distance from PT to the scroll margin position.  This prevents
12322         try_scrolling from unnecessarily failing when
12323         scroll-conservatively is set to a value slightly larger than the
12324         window height.  Clean up the case of PT below the margin at bottom
12325         of window: scroll_max can no longer be INT_MAX.  When aggressive
12326         scrolling is in use, don't let point enter the opposite scroll
12327         margin as result of the scroll.
12328         (syms_of_xdisp) <scroll-conservatively>: Document the
12329         threshold of 100 lines for never-recentering scrolling.
12330
12331 2011-03-31  Juanma Barranquero  <lekktu@gmail.com>
12332
12333         * dispextern.h (move_it_by_lines):
12334         * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
12335         since 2000-12-29T14:24:09Z!gerd@gnu.org.  All callers changed.
12336         (message_log_check_duplicate): Remove parameters `prev_bol' and
12337         `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org.  All callers changed.
12338         (redisplay_internal): Remove parameter `preserve_echo_area',
12339         unused since 1999-07-21T21:43:52Z!gerd@gnu.org.  All callers changed.
12340
12341         * indent.c (Fvertical_motion):
12342         * window.c (window_scroll_pixel_based, Frecenter):
12343         Don't pass `need_y_p' to `move_it_by_lines'.
12344
12345 2011-03-30  Stefan Monnier  <monnier@iro.umontreal.ca>
12346
12347         * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12348         steal a few bits to be more compact.
12349         (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12350         Remove unneeded casts.
12351
12352         * bytecode.c (Fbyte_code): CAR and CDR can GC.
12353
12354 2011-03-30  Zachary Kanfer  <zkanfer@gmail.com>  (tiny change)
12355
12356         * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12357         binding" message (bug#7967).
12358
12359 2011-03-30  Paul Eggert  <eggert@cs.ucla.edu>
12360
12361         Fix more problems found by GCC 4.6.0's static checks.
12362
12363         * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12364         Remove unused local var.
12365
12366         * editfns.c (Fmessage_box): Remove unused local var.
12367
12368         * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12369         (note_mode_line_or_margin_highlight, note_mouse_highlight):
12370         Omit unused local vars.
12371         * window.c (shrink_windows): Omit unused local var.
12372         * menu.c (digest_single_submenu): Omit unused local var.
12373         * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12374         Omit unused local var.
12375
12376         * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12377         Don't assume string length fits in int.
12378         (keyremap_step, read_key_sequence): Use size_t for sizes.
12379         (read_key_sequence): Don't check last_real_key_start redundantly.
12380
12381         * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12382         instead of alloca (Bug#8344).
12383
12384         * eval.c (Fbacktrace): Don't assume nargs fits in int.
12385         (Fbacktrace_frame): Don't assume nframes fits in int.
12386
12387         * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12388
12389         * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12390         concerns.
12391
12392         * term.c (produce_glyphless_glyph): Remove unnecessary test.
12393
12394         * cm.c (calccost): Turn while-do into do-while, for clarity.
12395
12396         * keyboard.c (syms_of_keyboard): Use the same style as later
12397         in this function when indexing through an array.  This also
12398         works around GCC bug 48267.
12399
12400         * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12401
12402         * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12403
12404         * chartab.c (sub_char_table_ref_and_range): Redo for slight
12405         efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12406
12407         * keyboard.c, keyboard.h (num_input_events): Now size_t.
12408         This avoids undefined behavior on integer overflow, and is a bit
12409         more convenient anyway since it is compared to a size_t variable.
12410
12411         Variadic C functions now count arguments with size_t, not int.
12412         This avoids an unnecessary limitation on 64-bit machines, which
12413         caused (substring ...) to crash on large vectors (Bug#8344).
12414         * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
12415         (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
12416         All variadic functions and their callers changed accordingly.
12417         (struct gcpro.nvars): Now size_t, not int.  All uses changed.
12418         * data.c (arith_driver, float_arith_driver): Likewise.
12419         * editfns.c (general_insert_function): Likewise.
12420         * eval.c (struct backtrace.nargs, interactive_p)

12422         (funcall_lambda, mark_backtrace): Likewise.
12423         * fns.c (concat): Likewise.
12424         * frame.c (x_set_frame_parameters): Likewise.
12425         * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12426         0 if not found, not -1.  All callers changed.
12427
12428         * alloc.c (garbage_collect): Don't assume stack size fits in int.
12429         (stack_copy_size): Now size_t, not int.
12430         (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

12439         * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12440         unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12441         * character.h (CHAR_TO_BYTE8):

12453         (Qcommand_hook_internal): Remove, unused.
12454         (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define

12480         All callers changed.
12481         (string_buffer_position): Likewise.  Also, make static (it's never
12482         used outside xdisp.c).

12624
12625         * term.c (Fsuspend_tty, Fresume_tty):

12627         * window.c (temp_output_buffer_show):

12637         Use Frun_hooks.

12639         unconditionally since it does the check itself.

12641 2011-03-23  Paul Eggert  <eggert@cs.ucla.edu>
12642
12643         Fix more problems found by GCC 4.5.2's static checks.
12644
12645         * coding.c (encode_coding_raw_text): Avoid unnecessary test
12646         the first time through the loop, since we know p0 < p1 then.
12647         This also avoids a gcc -Wstrict-overflow warning.
12648
12649         * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12650         leading to a memory leak, possible in functions like
12651         load_charset_map_from_file that can allocate an unbounded number
12652         of objects (Bug#8318).
12653
12654         * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12655         that could (at least in theory) be that large.
12656
12657         * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12658         This is less likely to overflow, and avoids undefined behavior if
12659         overflow does occur.  All callers changed.  Use strtoul to scan
12660         for the unsigned long integer.
12661         (pint2hrstr): Simplify and tune code slightly.
12662         This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
12663
12664         * scroll.c (do_scrolling): Work around GCC bug 48228.
12665         See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
12666
12667         * frame.c (Fmodify_frame_parameters): Simplify loop counter.
12668         This also avoids a warning with gcc -Wstrict-overflow.
12669         (validate_x_resource_name): Simplify count usage.
12670         This also avoids a warning with gcc -Wstrict-overflow.
12671
12672         * fileio.c (Fcopy_file): Report error if fchown or fchmod
12673         fail (Bug#8306).
12674
12675         * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12676
12677         * process.c (Fmake_network_process): Use socklen_t, not int,
12678         where POSIX says socklen_t is required in portable programs.
12679         This fixes a porting bug on hosts like 64-bit HP-UX, where
12680         socklen_t is wider than int (Bug#8277).
12681         (Fmake_network_process, server_accept_connection):
12682         (wait_reading_process_output, read_process_output):
12683         Likewise.
12684
12685         * process.c: Rename or move locals to avoid shadowing.
12686         (list_processes_1, Fmake_network_process):
12687         (read_process_output_error_handler, exec_sentinel_error_handler):
12688         Rename or move locals.
12689         (Fmake_network_process): Define label "retry_connect" only if needed.
12690         (Fnetwork_interface_info): Fix pointer signedness.
12691         (process_send_signal): Add cast to avoid pointer signedness problem.
12692         (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
12693         (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
12694
12695         Make tparam.h and terminfo.c consistent.
12696         * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12697         Include tparam.h instead, since it declares them.
12698         * cm.h (PC): Remove extern decl; tparam.h now does this.
12699         * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12700         * terminfo.c: Include tparam.h, to check interfaces.
12701         (tparm): Make 1st arg a const pointer in decl.  Put it at top level.
12702         (tparam): Adjust signature to match interface in tparam.h;
12703         this removes some undefined behavior.  Check that outstring and len
12704         are zero, which they always are with Emacs.
12705         * tparam.h (PC, BC, UP): New extern decls.
12706
12707         * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12708         (xftfont_open): Rename locals to avoid shadowing.
12709
12710         * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
12711         (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
12712         (OTF_TAG_SYM): Omit macro if not needed.
12713         (ftfont_list): Remove unused local.
12714         (get_adstyle_property, ftfont_pattern_entity):
12715         (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
12716         Rename locals to avoid shadowing.
12717
12718         * xfont.c (xfont_list_family): Mark var as initialized.
12719
12720         * xml.c (make_dom): Now static.
12721
12722         * composite.c (composition_compute_stop_pos): Rename local to
12723         avoid shadowing.
12724         (composition_reseat_it): Remove unused locals.
12725         (find_automatic_composition, composition_adjust_point): Likewise.
12726         (composition_update_it): Mark var as initialized.
12727         (find_automatic_composition): Mark vars as initialized,
12728         with a FIXME (Bug#8290).
12729
12730         character.h: Rename locals to avoid shadowing.
12731         * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
12732         (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
12733         (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
12734         (BUF_DEC_POS): Be more systematic about renaming local temporaries
12735         to avoid shadowing.
12736
12737         * textprop.c (property_change_between_p): Remove; unused.
12738
12739         * intervals.c (interval_start_pos): Now static.
12740
12741         * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
12742
12743         * atimer.c (start_atimer, append_atimer_lists, set_alarm):
12744         Rename locals to avoid shadowing.
12745
12746         * sound.c (wav_play, au_play, Fplay_sound_internal):
12747         Fix pointer signedness.
12748         (alsa_choose_format): Remove unused local var.
12749         (wav_play): Initialize a variable to 0, to prevent undefined
12750         behavior (Bug#8278).
12751
12752         * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12753
12754         * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12755
12756         * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12757         clobbering (Bug#8298).
12758         * sysdep.c (sys_subshell): Likewise.
12759         Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12760
12761         * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12762         This should get cleaned up, so that child_setup has the
12763         same signature on all platforms.
12764
12765         * callproc.c (call_process_cleanup): Now static.
12766         (relocate_fd): Rename locals to avoid shadowing.

12769
12770         * xterm.c (x_clear_frame): Remove XClearWindow call.  This appears
12771         not to be necessary, and produces flickering.
12772

12808
12809         * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
12810         That way, the code declares only the vars that it needs.
12811         * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.

12823
12824         * unexelf.c (unexec): Name an expression,
12825         to avoid gcc -Wbad-function-cast warning.
12826         Use a different way to cause a compilation error if anyone uses

12828         (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
12829
12830         * deps.mk (unexalpha.o): Remove; unused.

12860
12861         * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.

12921         they're used.
12922         (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
12923         ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
12924         needed otherwise.
12925         (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
12926         (GC_STRING_CHARS): Remove; not used.
12927         (Fmemory_limit): Cast sbrk's returned value to char *.
12928
12929         * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
12930         avoids undefined behavior in theory.
12931
12932         * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
12933
12934         Use functions, not macros, for up- and down-casing (Bug#8254).
12935         * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12936         (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove.  All callers changed
12937         to use the following functions instead of these macros.
12938         (downcase): Adjust to lack of DOWNCASE_TABLE.  Return int, not
12939         EMACS_INT, since callers assume the returned value fits in int.
12940         (upcase1): Likewise, for UPCASE_TABLE.
12941         (uppercasep, lowercasep, upcase): New static inline functions.
12942         * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
12943         the race-condition problem in the old DOWNCASE.
12944
12945         * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
12946         Rename locals to avoid shadowing.
12947         (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
12948         (regex_compile, re_search_2, re_match_2_internal):
12949         Remove unused local vars.
12950         (FREE_VAR): Rewrite so as not to use empty "else",
12951         which gcc can warn about.
12952         (regex_compile, re_match_2_internal): Mark locals as initialized.
12953         (RETALLOC_IF): Define only if needed.
12954         (WORDCHAR_P): Likewise.  This one is never needed, but is used
12955         only in a comment talking about a compiler bug, so put inside
12956         the #if 0 of that comment.
12957         (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
12958         (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
12959         Remove; unused.
12960
12961         * search.c (boyer_moore): Rename locals to avoid shadowing.
12962         * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
12963         (PREV_CHAR_BOUNDARY): Likewise.
12964
12965         * search.c (simple_search): Remove unused var.
12966
12967         * dired.c (compile_pattern): Move decl from here ...
12968         * lisp.h: ... to here, so that it can be checked.
12969         (struct re_registers): New forward decl.
12970
12971         * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
12972
12973         * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
12974         All uses changed.
12975         (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
12976         Rename locals to avoid shadowing.
12977         (Fvertical_motion): Mark locals as initialized.
12978
12979         * casefiddle.c (casify_object, casify_region): Now static.
12980         (casify_region): Mark local as initialized.
12981
12982         * cmds.c (internal_self_insert): Rename local to avoid shadowing.
12983
12984         * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
12985         New macros, so that the caller can use some names other than
12986         gcpro1, gcpro2, etc.
12987         (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
12988         of the new macros.
12989         (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
12990         argument, for consistency with GCPRO2_VAR, etc: it is now the
12991         prefix of the variable, not the variable itself.  All uses
12992         changed.
12993         * dired.c (directory_files_internal, file_name_completion):
12994         Rename locals to avoid shadowing.
12995
12996         Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
12997         An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
12998         dired.c's scmp function, had undefined behavior.
12999         * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13000         (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13001         * buffer.h: ... to here, because these macros use current_buffer,
13002         and the new implementation with inline functions needs to have
13003         current_buffer in scope now, rather than later when the macros
13004         are used.
13005         (downcase, upcase1): New static inline functions.
13006         (DOWNCASE, UPCASE1): Reimplement using these functions.
13007         This avoids undefined behavior in expressions like
13008         DOWNCASE (x) == DOWNCASE (y), which previously suffered
13009         from race conditions in accessing the global variables
13010         case_temp1 and case_temp2.
13011         * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13012         * lisp.h (case_temp1, case_temp2): Remove their decls.
13013         * character.h (ASCII_CHAR_P): Move from here ...
13014         * lisp.h: ... to here, so that the inline functions mentioned
13015         above can use them.
13016
13017         * dired.c (directory_files_internal_unwind): Now static.
13018
13019         * fileio.c (file_name_as_directory, directory_file_name):
13020         (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13021         Now static.
13022         (file_name_as_directory): Use const pointers when appropriate.
13023         (Fexpand_file_name): Likewise.  In particular, newdir might
13024         point at constant storage, so make it a const pointer.
13025         (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13026         (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13027         signedness issues.
13028         (Fset_file_times, Finsert_file_contents, auto_save_error):
13029         Rename locals to avoid shadowing.
13030
13031         * minibuf.c (choose_minibuf_frame_1): Now static.
13032         (Ftry_completion, Fall_completions): Rename or remove locals
13033         to avoid shadowing.
13034
13035         * marker.c (bytepos_to_charpos): Remove; unused.
13036
13037         * lisp.h (verify_bytepos, count_markers): New decls,
13038         so that gcc does not warn that these functions aren't declared.
13039
13040         * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13041         (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13042         (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13043         (copy_text): Remove unused local var.
13044
13045         * filelock.c (within_one_second): Now static.
13046         (lock_file_1): Rename local to avoid shadowing.
13047
13048         * buffer.c (fix_overlays_before): Mark locals as initialized.
13049         (fix_start_end_in_overlays): Likewise.  This function should be
13050         simplified by using pointers-to-pointers, but that's a different
13051         matter.
13052         (switch_to_buffer_1): Now static.
13053         (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13054         (report_overlay_modification): Rename locals to avoid shadowing.
13055
13056         * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13057         Fix pointer signedness issue.
13058         (sys_subshell): Mark local as volatile if checking for lint,
13059         to suppress a gcc -Wclobbered warning that does not seem to be right.
13060         (MAXPATHLEN): Define only if needed.
13061
13062         * process.c (serial_open, serial_configure): Move decls from here ...
13063         * systty.h: ... to here, so that they can be checked.
13064
13065         * fns.c (get_random, seed_random): Move extern decls from here ...
13066         * lisp.h: ... to here, so that they can be checked.
13067
13068         * sysdep.c (reset_io): Now static.
13069         (wait_for_termination_signal): Remove; unused.

13072         (copy_keymap_item, append_key, push_text_char_description):
13073         Now static.
13074         (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13075         (DENSE_TABLE_SIZE): Remove; unused.
13076         (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13077         (describe_map_tree):
13078         Rename locals to avoid shadowing.
13079
13080         * keyboard.c: Declare functions static if they are not used elsewhere.
13081         (echo_char, echo_dash, cmd_error, top_level_2):
13082         (poll_for_input, handle_async_input): Now static.

13084         (make_lispy_event, make_lispy_movement, apply_modifiers):
13085         (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

13087         (Fread_key_sequence_vector): Rename locals to avoid shadowing.
13088         (read_key_sequence, read_char): Mark locals as initialized.
13089         (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.
13090
13091         * keyboard.h (make_ctrl_char): New decl.
13092         (mark_kboards): Move decl here ...
13093         * alloc.c (mark_kboards): ... from here.
13094
13095         * lisp.h (force_auto_save_soon): New decl.
13096
13097         * emacs.c (init_cmdargs): Rename local to avoid shadowing.
13098         (DEFINE_DUMMY_FUNCTION): New macro.
13099         (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
13100         Use it.
13101         (main): Add casts to avoid warnings
13102         if GCC considers string literals to be constants.
13103
13104         * lisp.h (fatal_error_signal): Add decl, since it's exported.
13105
13106         * dbusbind.c: Pointer signedness fixes.
13107         (xd_signature, xd_append_arg, xd_initialize):

13111         (Fdbus_register_signal): Use SSDATA when the context wants char *.
13112
13113         * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
13114         if GCC considers string literals to be constants.

13165         (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).

13226         Improve quality of tests for time stamp overflow.
13227         For example, without this patch (encode-time 0 0 0 1 1
13228         1152921504606846976) returns the obviously-bogus value (-948597
13229         62170) on my RHEL 5.5 x86-64 host.  With the patch, it correctly
13230         reports time overflow.  See
13231         <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.

13240         (make_time): Use list2 instead of Fcons twice.
13241         (Fdecode_time): More accurate test for out-of-range times.
13242         (check_tm_member): New function.

13409         a block, when the outer 'i' will do.

13458         Move these decls to tparam.h, and make them agree with what
