* Fix comment detection on open parensNoam Postavsky2017-01-231-0/+85
| | | | | | | | | | | | | | | Characters having both open paren syntax and comment start syntax were being detected as open parens even when they should have been part a comment starter (Bug#24870). * src/syntax.c (in_2char_comment_start): New function, extracted from `scan_sexps_forward'. (scan_sexps_forward): Add check for a 2-char comment starter before the loop. Inside the loop, do that check after incrementing the 'from' character index. Move the single char comment syntax cases into the switch instead of special casing them before. * test/src/syntax-tests.el (parse-partial-sexp-paren-comments): (parse-partial-sexp-continue-over-comment-marker): New tests.
* Check that variable lists are actually listsPhilipp Stephani2017-01-191-0/+10
| | | | | | | | | | 'let' and 'let*' document that their first argument has to be a list, but don't check for that; instead, they allow (and silently ignore) other types. Introduce an explicit type check. * src/eval.c (Flet, FletX): Check that the variable list is indeed a list. * test/src/eval-tests.el: Add unit tests.
* Rudimentary error handling for non-main threadsEli Zaretskii2017-01-181-4/+13
| | | | | | | | | | | | | | * src/thread.c (last_thread_error): New static variable. (syms_of_threads): Staticpro it. (record_thread_error, Fthread_last_error): New functions. (syms_of_threads): Defsubr Fthread_last_error. * doc/lispref/threads.texi (Basic Thread Functions): Document thread-last-error. * test/src/thread-tests.el (thread-errors, thread-signal-early) (threads-condvar-wait): Test the values returned by thread-last-error.
* Fix last changeEli Zaretskii2017-01-131-9/+9
| | | | | | * test/src/thread-tests.el (threads-condvar-wait): Revert previous change. Make sure no other threads from previous tests are running, to avoid interfering with our thread counts.
* Fix the new condvar testEli Zaretskii2017-01-131-2/+3
| | | | | | * test/src/thread-tests.el (threads-condvar-wait): Enlarge the time we sleep in the main thread to let the other thread process notifications.
* Minor improvements in the new condvar testEli Zaretskii2017-01-131-11/+14
| | | | | | | | * test/src/thread-tests.el (threads-test-condvar-wait): Use with-mutex instead of emulating it inline. (threads-condvar-wait): Improve comments. Check that the new thread is alive before waiting for it to become blocked on the conditional variable.
* Fix a bug in waiting for condition variableEli Zaretskii2017-01-131-0/+41
| | | | | | | | | | | * src/thread.c (lisp_mutex_lock, lisp_mutex_unlock) (lisp_mutex_unlock_for_wait, condition_wait_callback) (condition_notify_callback): Improve commentary. (condition_wait_callback): Call post_acquire_global_lock before attempting to lock the mutex, to make sure the lock's owner is recorded correctly. * test/src/thread-tests.el (threads-condvar-wait): New test.
* 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 ‘[[: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.
