* | Fix two fringe bitmapsEli Zaretskii2020-04-251-2/+2
| | | | | | | | | | * src/fringe.c (question_mark_bits, exclamation_mark_bits): Fix the numerical values. (Bug#40805)
* | Fix display of composed text with :box face attributeEli Zaretskii2020-04-236-26/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/xdisp.c (get_next_display_element): For a composition on a display or overlay string, set the end_of_box_run_p flag if the string ends at the last character included in the composition. (fill_gstring_glyph_string): Fix the way the width of a gstring glyph string is calculated: use the values calculated in gui_produce_glyphs, since the latter adjusts the width due to the face's ':box' attribute. * src/xterm.c (x_draw_glyph_string_box): * src/w32term.c (w32_draw_glyph_string_box): * src/nsterm.m (ns_dumpglyphs_box_or_relief): Support automatic compositions, which have the right_box_line_p flag set on the last glyph produced from the composition. (Bug#40687) * src/w32term.c (w32_compute_glyph_string_overhangs): Update to be consistent with xterm.c in its support of automatic composition glyph strings. * src/dispextern.h (enum glyph_type): More accurate commentary. * src/.gdbinit (pgx): Display slice.img members only for image glyphs.
* | text-char-description minor cleanupPaul Eggert2020-04-221-15/+8
| | | | | | | | | | | | * src/keymap.c (push_text_char_description): Omit useless code. (Ftext_char_description): Minor code cleanup, inspired by seeing an incorrect comment about MAX_MULTIBYTE_LENGTH’s value.
* | Tweak multibyte parsing loopsPaul Eggert2020-04-221-3/+3
| | | | | | | | | | | | * src/character.c (parse_str_as_multibyte, str_as_multibyte): Let the fast loop run a little longer, fixing what appears to be an off-by-1 performance nit.
* | Fix string-to-multibyte overlong sequence bugPaul Eggert2020-04-204-68/+87
| | | | | | | | | | | | | | | | | | * src/character.h (MULTIBYTE_LENGTH, MULTIBYTE_LENGTH_NO_CHECK): Remove, replacing with ... (multibyte_length): ... this new function. All callers changed. The new function rejects overlong multibyte forms. * test/src/buffer-tests.el (buffer-multibyte-overlong-sequences): New test.
* | Remove workaround from w32image.cEli Zaretskii2020-04-201-2/+0
| | | | | | | | | | | | * src/w32image.c (w32_load_image): Remove a workaround for a bug that is not needed anymore. This error was happening because GDI+ functions were called as CDECL, not as STDCALL.

* | Rework how GDI+ functions are loaded dynamically in w32image.cEli Zaretskii2020-04-191-43/+102
| | | | | | | | | | | | | | | | | | | | * src/w32image.c: Define correct WINGDIPAPI typedefs for GDI+ functions. We cannot use DEF_DLL_FN, since that is for functions with C calling conventions, whereas GDI+ functions are __stdcall. (gdiplus_init): Load functions from DLL manually, not via LOAD_DLL_FN, as the latter is for __cdecl functions. (w32_frame_delay): Initialize delay with a negative value, as zero is a valid delay.
* | Don't use Gnulib's explicit_bzero on MS-WindowsEli Zaretskii2020-04-191-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | This is a preventive change, since Gnulib was recently changed its explicit_bzero to call SecureZeroMemory on MS-Windows, disregarding systems older than XP, which didn't have it. * src/w32.c (explicit_bzero): New function. * nt/mingw-cfg.site (ac_cv_func_explicit_bzero): Avoid using the Gnulib replacement for explicit_bzero. * nt/inc/ms-w32.h (explicit_bzero): Add prototype.

* | Safeguard the fix of bug#40632Eli Zaretskii2020-04-181-2/+6
| | | | | | | | | | * src/xdisp.c (move_it_to): Restrict the recent fix to iteration through buffer text.
* | Don't abort when using GDI+ for imagesEli Zaretskii2020-04-181-7/+14
| | | | | | | | | | | | * src/w32image.c (decode_delay): Instead of aborting when the type of delay value is unrecognized, return an invalid negative value.
* | Fix loading multi-frame TIFF images via GDI+Juan José García-Ripoll2020-04-181-18/+24
| | | | | | | | | | | | | | * src/w32image.c (w32_frame_delay): Don't try to compute frame delay if GdipGetPropertyItemSize fails for PropertyTagFrameDelay. (w32_load_image): Don't add 'delay' member to metadata if the delay could not be determined.
* | Fix handling of child frames in prepare_menu_bars (Bug#40639)Martin Rudalics2020-04-181-5/+6
| | | | | | | | | | | | | | * src/xdisp.c (prepare_menu_bars): Call gui_consider_frame_title for child frames too (Bug#40639). Never try to update menu bar of a child frame. Do not exclude child frames from updating tool or tab bars.
* | Port recent character.h changes to --with-wide-intPaul Eggert2020-04-173-99/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/fns.c (mapcar1): * src/keymap.c (Fkey_description): * src/syntax.c (scan_lists): Prefer ptrdiff_t to EMACS_INT where either will do; this fixes newly-introduced type errors on --with-wide-int platforms where ptrdiff_t is narrower than EMACS_INT. * src/keymap.c (Fkey_description): Rework for clarity; remove goto. * src/syntax.c (scan_words, Fforward_comment, scan_lists)): Fix unlikely integer overflow problems that can occur on --with-wide-int platforms, and that were caught by the recent character.h changes.
* | Pacify gcc -Og x86-64Paul Eggert2020-04-171-1/+1
| | | | | | | | | | * src/editfns.c (Ftranslate_region_internal): Add UNINIT to pacify gcc -Og x86-64 (GCC 9.3.1 20200317 (Red Hat 9.3.1-1)).

* | Prefer inline functions in character.hPaul Eggert2020-04-175-161/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In character.h, replace macros with inline functions or enums when this is easy. This improves maintainability and on my platform (Fedora 31 x86-64, gcc -O2) improved CPU performance very slightly (0.3%) on ‘make compile-always’. * src/buffer.h (SANE_TAB_WIDTH, CHARACTER_WIDTH): Move here from character.h, and make them inline functions. Tune CHARACTER_WIDTH so that ASCII_CHAR_WIDTH is no longer needed. (sanitize_tab_width, sanitize_char_width): Move here from character.h. * src/character.h (MAX_CHAR, MAX_UNICODE_CHAR, MAX_1_BYTE_CHAR) (MAX_2_BYTE_CHAR, MAX_3_BYTE_CHAR, MAX_4_BYTE_CHAR) (MAX_5_BYTE_CHAR, MIN_MULTIBYTE_LEADING_CODE) (MAX_MULTIBYTE_LEADING_CODE, MAX_MULTIBYTE_LENGTH): Now enum constants instead of macros. * src/character.h (CHAR_BYTES): Redo to avoid conditional branches.

* | Remove UNSIGNED_CMPPaul Eggert2020-04-117-67/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I added this macro in 2011 to fix some signedness comparison bugs. However, it’s a weird macro and the bugs can be fixed in a more-straightforward way. This helps performance slightly (0.5%) on my platform (Fedora 31 x86-64, GCC 9.3.1 with -O2). * src/casefiddle.c (do_casify_natnum): Use simple comparison instead of UNSIGNED_CMP. * src/character.h (CHAR_VALID_P, SINGLE_BYTE_CHAR_P, CHAR_STRING): * src/composite.h (COMPOSITION_ENCODE_RULE_VALID): * src/lisp.h (ASCII_CHAR_P): Now an inline function, and uses simple comparison instead of UNSIGNED_CMP. * src/dispextern.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL) (IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): Move these to ... * src/frame.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL) (IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): ... here, and make them inline functions that no longer use UNSIGNED_CMP. * src/keyboard.c (read_char): UNSIGNED_CMP is not needed here since XFIXNAT always returns a nonnegative value. * src/lisp.h (UNSIGNED_CMP): Remove; no longer used.
* | Allow ENCODE_FILE and DECODE_FILE to use no-copy conversionMattias Engdegård2020-04-112-14/+19
| | | | | | | | | | | | | | | | | | | | They already did return their argument under some circumstances; this change broadens it to further reduce allocation in common cases (bug#40407). * src/coding.c (convert_string_nocopy): New function. (decode_file_name, encode_file_name): Use convert_string_nocopy. * src/coding.h (ENCODE_FILE, DECODE_FILE): Note the nocopy semantics.
