* Adjust how `replace-match' runs modification hooksLars Ingebrigtsen2021-07-311-1/+5
| | | | | | | | | | | | * src/editfns.c (Fsubst_char_in_region) (Ftranslate_region_internal): * src/cmds.c (internal_self_insert): Update callers. * src/insdel.c (replace_range): Allow inhibiting signal_after_change/update_compositions. * src/lisp.h: Update. * src/search.c (Freplace_match): Run the modification hooks at the end instead of before adjusting point (bug#42424).
* Remove unreliable test for match data clobberingNoam Postavsky2021-05-161-6/+5
| | | | | | * src/search.c (Freplace_match): Don't test for change in search_regs start and end, this is unreliable if change hooks modify text earlier in the buffer (bug#35264).

| | | | | | * lisp/subr.el (match-substitute-replacement): Use match-data--translate. * src/search.c (Fmatch_data__translate): Remove string restriction. * test/lisp/subr-tests.el (subr-match-substitute-replacement): New test.
* Fix replace-regexp-in-string substring match data translationMattias Engdegård2020-11-261-0/+18
| | | | | | | | | | | | | | | | | | | For certain patterns, re-matching the same regexp on the matched substring does not produce correctly translated match data (bug#15107 and bug#44861). Using a new builtin function also improves performance since the number of calls to string-match is halved. Reported by Kevin Ryde and Shigeru Fukaya. * lisp/subr.el (replace-regexp-in-string): Translate the match data using match-data--translate instead of trusting a call to string-match on the matched string to do the job. * test/lisp/subr-tests.el (subr-replace-regexp-in-string): Add test cases. * src/search.c (Fmatch_data__translate): New internal function. (syms_of_search): Register it as a subroutine.
* Fix a misleading comment in Freplace_matchLars Ingebrigtsen2020-10-181-1/+1
| | | | | * src/search.c (Freplace_match): Fix a misleading comment (bug#42424).
* Prefer Fvector to make_uninit_vectorPaul Eggert2020-08-151-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | Fvector is less error-prone than make_uninit_vector, as it avoids the possibility of a GC crash due to an uninitialized vector. So prefer Fvector to make_uninit_vector when this is easy (and when there's no significant performance difference). Inspired by a suggestion by Pip Cet in: https://lists.gnu.org/r/emacs-devel/2020-08/msg00313.html * src/ccl.c (Fregister_ccl_program): * src/ccl.c (Fregister_ccl_program): * src/charset.c (Fdefine_charset_internal): * src/font.c (Fquery_font, Ffont_info, syms_of_font): * src/fontset.c (font_def_new, Fset_fontset_font): * src/ftfont.c (ftfont_shape_by_flt): * src/hbfont.c (hbfont_shape): * src/macfont.m (macfont_shape): * src/search.c (Fnewline_cache_check): * src/xfaces.c (Fx_family_fonts): * src/xfns.c (Fx_window_property_attributes): Prefer Fvector to make_uninit_vector when either is easy. * src/fontset.c (font_def_new): Now a function with one less arg instead of a do-while macro, and renamed from FONT_DEF_NEW. All uses changed.
* Fix GC bugs related to uninitialized vectorsPaul Eggert2020-08-151-7/+2
| | | | | | | | | | | | | | | | | | | | | | Avoid problems if GC occurs while initializing a vector. Problem with Fdelete reported by Pip Cet in: https://lists.gnu.org/r/emacs-devel/2020-08/msg00313.html I looked for similar problems elsewhere and found quite a few. * src/coding.c (make_subsidiaries): * src/composite.c (syms_of_composite): * src/font.c (build_style_table, Ffont_get_glyphs): * src/nsselect.m (clean_local_selection_data): * src/nsxwidget.m (js_to_lisp): * src/syntax.c (init_syntax_once): * src/window.c (Fcurrent_window_configuration): * src/xselect.c (selection_data_to_lisp_data) (clean_local_selection_data): Use make_nil_vector instead of make_uninit_vector. * src/fns.c (Fdelete): * src/xwidget.c (webkit_js_to_lisp): Use allocate_nil_vector instead of allocate_vector. * src/search.c (Fnewline_cache_check): Use make_vector instead of make_uninit_vector.
* Simplify use of __lsan_ignore_objectPaul Eggert2020-08-031-6/+0
| | | | | | | | | * configure.ac: Use AC_CHECK_FUNCS_ONCE for __lsan_ignore_object. * src/buffer.c, src/data.c, src/emacs-module.c, src/regex-emacs.c: * src/search.c: Use __lsan_ignore_object unconditionally, and don’t include sanitizer/lsan_interface.h. * src/lisp.h (__lsan_ignore_object): Provide a dummy in the typical case where leak sanitization is not available.

* Improve accuracy of apropos commands that search doc stringsEli Zaretskii2020-05-031-5/+5
| | | | | | | | | | | | | | | | | | It is conceptually wrong for apropos commands that search doc strings to look for matches of several words only on the same line, because division of doc strings between lines is ephemeral. * lisp/apropos.el (apropos-parse-pattern): Accept an optional argument MULTILINE-P, and if that is non-nil, produce regexps that match words in the list even if they are separated by line boundaries. (apropos-value, apropos-local-value, apropos-documentation): Use the new optional argument in apropos commands that search multiline text, such as doc strings. * src/search.c (Fposix_looking_at, Fposix_string_match) (Fposix_search_backward, Fposix_search_forward): Make sure Posix appears in the doc strings near REGEXP, for better matches.
* Prefer more inline functions in character.hPaul Eggert2020-04-171-23/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/buffer.h (fetch_char_advance, fetch_char_advance_no_check) (buf_next_char_len, next_char_len, buf_prev_char_len) (prev_char_len, inc_both, dec_both): New inline functions, replacing the old character.h macros FETCH_CHAR_ADVANCE, FETCH_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS, INC_POS, BUF_DEC_POS, DEC_POS, INC_BOTH, DEC_BOTH respectively. All callers changed. These new functions all assume buffer primitives and so need to be here rather than in character.h. * src/casefiddle.c (make_char_unibyte): New static function, replacing the old MAKE_CHAR_UNIBYTE macro. All callers changed. (do_casify_unibyte_string): Use SINGLE_BYTE_CHAR_P instead of open-coding it. * src/ccl.c (GET_TRANSLATION_TABLE): New static function, replacing the old macro of the same name. * src/character.c (string_char): Omit 2nd arg. 3rd arg can no longer be NULL.

(make_char_multibyte): New static function, replacing the old macro MAKE_CHAR_MULTIBYTE. All callers changed. (CHAR_STRING_ADVANCE): Remove; all callers changed to use CHAR_STRING. (NEXT_CHAR_BOUNDARY): Remove; it was unused. (raw_prev_char_len): New inline function, replacing the old PREV_CHAR_BOUNDARY macro. All callers changed. (string_char_and_length): New inline function, replacing the old STRING_CHAR_AND_LENGTH macro. All callers changed. (STRING_CHAR): Rewrite in terms of string_char_and_length.

(fetch_string_char_advance): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_as_multibyte_advance): New inline function, replacing the old FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE macro. All callers changed. (fetch_string_char_advance_no_check): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE_NO_CHECK macro. All callers changed. * src/regex-emacs.c (HEAD_ADDR_VSTRING): Remove; no longer used. * src/syntax.c (scan_lists): Use dec_bytepos instead of open-coding it. * src/xdisp.c (string_char_and_length): Rename from string_char_and_length to avoid name conflict with new function in character.h. All callers changed.
* Improve integer range checkingPaul Eggert2020-04-051-8/+1
| | | | | | | | | | | | | | | | | | * src/bignum.c (check_integer_range, check_uinteger_max) (check_int_nonnegative): New functions. * src/frame.c (check_frame_pixels): New function. (Fset_frame_height, Fset_frame_width, Fset_frame_size): Use it. * src/lisp.h (CHECK_RANGED_INTEGER, CHECK_TYPE_RANGED_INTEGER): Remove these macros. Unless otherwise specified, all callers replaced by calls to check_integer_range, check_uinteger_range, check_int_nonnegative. * src/frame.c (gui_set_right_divider_width) (gui_set_bottom_divider_width): * src/nsfns.m (ns_set_internal_border_width): * src/xfns.c (x_set_internal_border_width): Using check_int_nonnegative means these functions no longer incorrectly reject negative bignums; they treat them as 0, just like negative fixnums.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a position argument to get-byte etc. is an out-of-range integer, treat it the same regardless of whether it is a fixnum or a bignum. * src/buffer.c (fix_position): New function. * src/buffer.c (validate_region): * src/character.c (Fget_byte): * src/coding.c (Ffind_coding_systems_region_internal) (Fcheck_coding_systems_region): * src/composite.c (Ffind_composition_internal): * src/editfns.c (Fposition_bytes, Fchar_after, Fchar_before) (Finsert_buffer_substring, Fcompare_buffer_substrings) (Fnarrow_to_region): * src/fns.c (Fsecure_hash_algorithms): * src/font.c (Finternal_char_font, Ffont_at): * src/fringe.c (Ffringe_bitmaps_at_pos): * src/search.c (search_command): * src/textprop.c (get_char_property_and_overlay): * src/window.c (Fpos_visible_in_window_p): * src/xdisp.c (Fwindow_text_pixel_size): Use it instead of CHECK_FIXNUM_COERCE_MARKER, so that the code is simpler and treats bignums consistently with fixnums. * src/buffer.h (CHECK_FIXNUM_COERCE_MARKER): Define here rather than in lisp.h, and reimplement in terms of fix_position so that it treats bignums consistently with fixnums. * src/lisp.h (CHECK_FIXNUM_COERCE_MARKER): Move to buffer.h. * src/textprop.c (validate_interval_range): Signal with original bounds rather than modified ones.

* Avoid crashes when casifying noncontiguous regionsPaul Eggert2019-09-221-1/+1
| | | | | | | | | | | | | | | | | | | | This is a followon fix for Bug#37477. * lisp/simple.el (region-extract-function): Use setq here, since the var is now defined in C code. * src/casefiddle.c (casify_pnc_region): New function. (Fupcase_region, Fdowncase_region, Fcapitalize_region) (Fupcase_initials_region): Use it. (Fupcase_initials_region): Add region-noncontiguous-p flag for consistency with the others. All uses changed.

* Fix rare undefined behaviors in replace-matchPaul Eggert2019-08-031-69/+38
| | | | | | | | | | | * src/search.c (Freplace_match): Simplify by caching search_regs components. Fix sanity check for out-of-range subscripts; it incorrectly allowed negative subscripts, subscripts equal to search_regs.num_regs, and it had undefined behavior for subscripts outside ptrdiff_t range. Improve wording of newly-introduced replace-match diagnostic. Rework use of opoint, to avoid setting point to an out-of-range value in rare cases involving modification hooks.
* Fix error message in replace-match for subexpressionsLars Ingebrigtsen2019-08-031-0/+6

* | Release regexp before signalling overflow errorMattias Engdegård2019-03-301-1/+6
| | | | | | | | | | | | * src/search.c (looking_at_1, search_buffer_re): Unfreeze the regexp buffer before signalling a matcher overflow, since the error processing may require quite some regexp use as well (Bug#34910).

* | Make regex matching reentrant; update syntax during matchDaniel Colascione2018-06-161-378/+417
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/lisp.h (compile_pattern): Remove prototype of now-internal function. * src/regex.c (POS_AS_IN_BUFFER): Consult gl_state instead of re_match_object: the latter can change in Lisp. (re_match_2_internal): Switch back to UPDATE_SYNTAX_* FROM UPDATE_SYNTAX_FAST*, allowing calls into Lisp. * src/regex.h (re_match_object): Uncomment declaration. * src/search.c (struct regexp_cache): Add `busy' field. (thaw_buffer_relocation): Delete; rely on unbind. (compile_pattern_1): Assert pattern isn't busy. (shrink_regexp_cache): Don't shrink busy patterns. (clear_regexp_cache): Don't nuke busy patterns. (unfreeze_pattern, freeze_pattern): New functions. (compile_pattern): Return a regexp_cache pointer instead of the re_pattern_buffer, allowing callers to use `freeze_pattern' if needed. Do not consider busy patterns as cache hit candidates; error if we run out of non-busy cache entries. (looking_at_1, fast_looking_at): Snapshot Vinhibit_changing_match_data; mark pattern busy while we're matching it; unbind. (string_match_1, fast_string_match_internal) (fast_c_string_match_ignore_case): Adjust for compile_pattern return type. (search_buffer_re): Regex code from old search_buffer moved here; snapshot Vinhibit_changing_match_data; mark pattern busy while we're matching it; unbind. (search_buffer_non_re): Non-regex code from old search_buffer moved here. (search_buffer): Split into search_buffer_re, search_buffer_non_re. (syms_of_search): Staticpro re_match_object, even though we really shouldn't have to. * src/syntax.h (UPDATE_SYNTAX_TABLE_FORWARD_FAST): (UPDATE_SYNTAX_TABLE_FAST): Remove. * src/thread.h (struct thread_state): Remove m_re_match_object, which is global again. (It never needs to be preserved across thread switch.)
* | Remove commented-out code in compile_pattern_1Daniel Colascione2018-06-161-7/+0
|/ | | | * src/search.c (compile_pattern_1): Remove commented-out code.
* Note caveat for backward regexp searching in docstring (Bug#31584)Noam Postavsky2018-05-251-1/+4
| | | | | | | * src/search.c (Fre_search_backward): Emphasize that backwards searches may give shorter than expected matches. * doc/lispref/searching.texi (Regexp Search): Add an anchor for re-search-backward to reference.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
* Merge with gnulib, pacifying GCC 7Paul Eggert2017-05-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This incorporates: 2017-05-16 manywarnings: update for GCC 7 2017-05-15 sys_select: Avoid "was expanded before it was required" * configure.ac (nw): Suppress GCC 7’s new -Wduplicated-branches and -Wformat-overflow=2 options, due to too many false alarms. * doc/misc/texinfo.tex, lib/strftime.c, m4/manywarnings.m4: Copy from gnulib. * m4/gnulib-comp.m4: Regenerate. * src/coding.c (decode_coding_iso_2022): Fix bug uncovered by -Wimplicit-fallthrough. * src/conf_post.h (FALLTHROUGH): New macro. Use it to mark all switch cases that fall through. * src/editfns.c (styled_format): Use !, not ~, on bool. * src/gtkutil.c (xg_check_special_colors): When using sprintf, don’t trust Gtk to output colors in [0, 1] range. (xg_update_scrollbar_pos): Avoid use of possibly-uninitialized bool; this bug was actually caught by Clang. * src/search.c (boyer_moore): Tell GCC that CHAR_BASE, if nonzero, must be a non-ASCII character. * src/xterm.c (x_draw_glyphless_glyph_string_foreground): Tell GCC that glyph->u.glyphless.ch must be a character.
