* Add support for Unicode whitespace in [:blank:]Philipp Stephani2017-01-061-1/+1
| | | | | | | | | | | | | | | | See Bug#25366. * src/character.c (blankp): New function for checking Unicode horizontal whitespace. * src/regex.c (ISBLANK): Use 'blankp' for non-ASCII horizontal whitespace. (BIT_BLANK): New bit for range table. (re_wctype_to_bit, execute_charset): Use it. * test/lisp/subr-tests.el (subr-tests--string-match-p--blank): Add unit test for [:blank:] character class. * test/src/regex-tests.el (test): Adapt unit test. * doc/lispref/searching.texi (Char Classes): Document new Unicode behavior for [:blank:].

* Avoid crashing if a new thread is signaled right awayEli Zaretskii2016-12-121-0/+9
| | | | | | | | | | | * src/thread.c (post_acquire_global_lock): Don't raise the pending signal if the thread's handlers were not yet set up, as that will cause Emacs to exit with a fatal error. This can happen if a thread is signaled as soon as make-thread returns, before the new thread had an opportunity to acquire the global lock, set up the handlers, and call the thread function. * test/src/thread-tests.el (thread-signal-early): New test.
* Fix point motion in cloned buffersEli Zaretskii2016-12-121-1/+11
| | | | | | | | | | | | | | | | | | * src/thread.c (post_acquire_global_lock): Call set_buffer_internal_2 instead of tricking set_buffer_internal_1 into resetting the current buffer even if it didn't change. This avoids bug#25165, caused by failing to record the modified values of point and mark, because current_buffer was set to NULL. Also, don't bother re-setting the buffer if there was no thread switch, as that just wastes cycles. * src/buffer.c (set_buffer_internal_2): New function, with most of the body of set_buffer_internal_1, but without the test for B being identical to the current buffer. (set_buffer_internal_1): Call set_buffer_internal_2 if B is not identical to the current buffer. * src/buffer.h (set_buffer_internal_2): Add prototype. * test/src/thread-tests.el (thread-sticky-point): New test.

* Split regex character class test into smaller chunksMichal Nazarewicz2016-09-091-44/+46
| | | | | | | | | | | | | | | | | | | | | | | | Having one test for all character classes it is not always trivial to determine which class is failing. This happens when failure is caused by ‘(should (equal (point) (point-max)))’ not being met. With per-character class tests, it is immidiatelly obvious which test causes issues plus tests for all classes are run even if some of them fail. * test/src/regex-tests.el (regex-character-classes): Delete and split into… (regex-tests-alnum-character-class, regex-tests-alpha-character-class, regex-tests-ascii-character-class, regex-tests-blank-character-class, regex-tests-cntrl-character-class, regex-tests-digit-character-class, regex-tests-graph-character-class, regex-tests-lower-character-class, regex-tests-multibyte-character-class, regex-tests-nonascii-character-class, regex-tests-print-character-class, regex-tests-punct-character-class, regex-tests-space-character-class, regex-tests-unibyte-character-class, regex-tests-upper-character-class, regex-tests-word-character-class, regex-tests-xdigit-character-class): …new tests.

| | | | | | | | | | | | | | | | [82a487d: Fix reading of regex-resources in regex-tests] attempted to fix regex-tests failing when run from the source tree (i.e. via make) by hard-coding path to regex-resources directory relative to the test directory. This fixed runs from the tree but broke the test when run using other methods. Fix by trying ‘load-file-name’ or ‘buffer-file-name’, whichever is set. * test/src/regex-tests.el (regex-tests--resources-dir): New variable storing path to the regex-resources directory. (regex-tests-generic-line): Use aforementioned variable.

* Fix reading of regex-resources in regex-testsMichal Nazarewicz2016-08-021-6/+5
| | | | | | | | | | | * test/src/regex-tests.el (regex-tests-generic-line): Referring to ‘buffer-file-name’ does not work when running the test from command line, i.e. via make, which results in (wrong-type-argument stringp nil) failures. Replace it with hard-coded path. (regex-tests-BOOST, regex-tests-PCRE, regex-tests-PTESTS-whitelist, regex-tests-TESTS-whitelist): ‘regex-tests-generic-line’ now includes the ‘regex-resources’ path component so the tests don’t need to specify it explicitly.

* Fix ‘[[:cc:]]*literal’ regex failing to match ‘literal’ (bug#24020)Michal Nazarewicz2016-07-251-0/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The regex engine tries to optimise Kleene star by avoiding backtracking when it can detect that star’s operand cannot match what follows it in the pattern. For example, when ‘[[:alpha:]]*1’ tries to match a ‘foo’, the engine will test the longest match for ‘[[:alpha:]]*’, namely ’foo’ which is the entire string. Literal digit one still present in the pattern will however not match the remaining empty string. Normally, backtracking would be performed trying a shorter match for the character class (namely ‘fo’ leaving ‘o’ in the string), but since the engine knows whatever would be put back into the string cannot possibly match literal digit one so no backtracking will be attempted. In the regexes of the form ‘[[:CC:]]*X’, the optimisation can be applied if the character class CC does not match character X. In the above example, this holds because digit one is not in alpha character class. This test is performed by mutually_exclusive_p function but it did not check class bits of a charset opcode. This resulted in an assumption that character classes do not match multibyte characters. For example, it would incorrectly conclude that [[:alpha:]] doesn’t match ‘ż’. This, in turn, led to the aforementioned Kleene star optimisation being incorrectly applied in patterns such as ‘[[:graph:]]*☠’ (which should match ‘☠’ but doesn’t as can be tested by executing (string-match-p "[[:graph:]]*☠" "☠") which should return 0 but instead yields nil. This issue affects any class witch matches multibyte characters, i.e. if ‘[[:cc:]]’ matches a multibyte character X then ‘[[:cc:]]*X’ will fail to match ‘X’. * src/regex.c (executing_charset): A new function for executing the charset and charset_not opcodes. It performs check on the character taking into consideration existing bitmap, range table and class bits. It also advances the pointer in the regex bytecode past the parsed opcode. (CHARSET_LOOKUP_RANGE_TABLE_RAW, CHARSET_LOOKUP_RANGE_TABLE): Removed. Code now included in executing_charset. (mutually_exclusive_p, re_match_2_internal): Changed to take advantage of executing_charset function. * test/src/regex-tests.el: New file with tests for the character class matching.

Reject out-of-range integers, floating-point numbers, and strings with trailing junk. * src/lread.c (character_name_to_code): Call char-from-name instead of inspecting ucs-names directly, so that we handle computed names like "VARIATION SELECTOR-1". Do not use an auto string, since char-from-name might GC. * test/src/lread-tests.el: Add tests for new behavior, and fix some old tests that were wrong.
* Improve character name escapesPaul Eggert2016-04-211-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/nonascii.texi (Character Properties): Avoid duplication of Unicode names. Reformat examples to fit in narrow pages. * doc/lispref/objects.texi (General Escape Syntax): Simplify and better-organize explanation of \N{...} escapes. * src/character.h (CHAR_SURROGATE_PAIR_P): Remove; unused. (char_surrogate_p): New inline function. * src/lread.c: Do not include string.h; no longer needed. (invalid_character_name, check_scalar_value): Remove; the ideas behind these functions are now bundled into character_name_to_code. (character_name_to_code): Remove undocumented support for "CJK IDEOGRAPH-XXXX" names, as "U+XXXX" suffices. Reject monstrosities like "\N{U+-0}" and null bytes in \N escapes. Reject floating point in \N escapes instead of returning garbage. Use AUTO_STRING_WITH_LEN to lessen pressure on the garbage collector. * test/src/lread-tests.el (lread-char-number, lread-char-name) (lread-string-char-number, lread-string-char-name): Test runtime behavior, not compile-time, as the test framework is not set up to test compile-time. (lread-char-surrogate-1, lread-char-surrogate-2) (lread-char-surrogate-3, lread-char-surrogate-4) (lread-string-char-number-2, lread-string-char-number-3): New tests. (lread-string-char-number-1): Rename from lread-string-char-number.
* Use 'ucs-names' for character name escapesPhilipp Stephani2016-04-211-2/+9
| | | | | | | | | | * lread.c (invalid_character_name, check_scalar_value) (parse_code_after_prefix, character_name_to_code): New helper functions that use 'ucs-names' and parsing for CJK ideographs. (read_escape): Use helper functions. (syms_of_lread): New symbol 'ucs-names'. * test/src/lread-tests.el: New tests; fix a couple of bugs in existing tests.
