* 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.

* Limit bidi_find_bracket_pairs to MAX_ALLOCAPaul Eggert2017-06-211-7/+7
| | | | | | | | * src/bidi.c (MAX_BPA_STACK): Now a constant, not a macro. Shrink it to allow for the two struct bidi_it objects in the same frame. (PUSH_BPA_STACK): Avoid integer overflow with enormous bidi cache. (bidi_find_bracket_pairs): Use compile-time check instead of runtime.

* Rework C source files to avoid ^(Paul Eggert2016-03-101-2/+2
| | | | | | | | Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.
* Speed up redisplay of binary files with long series of nullsEli Zaretskii2016-03-061-6/+34
| | | | | | | | | | | | | | * src/bidi.c (bidi_resolve_weak): Avoid entering a loop searching for a character needed for resolving the type of a series of BN and ET characters, as required by rule W5 of UAX#9, if the results of the resolution are known in advance, because we are at level zero, and the previous strong character was L. (bidi_resolve_neutral): Partially resurrect the optimization for a long series of control characters in an otherwise strictly L2R text. (bidi_level_of_next_char): Don't enter the loop that searches for a paragraph separator if the current character is already at base embedding level. (Bug#22739)
* Fix reordering of bidi text in an isolate inside an overrideEli Zaretskii2016-03-011-5/+8
| | | | | | | | * src/bidi.c (bidi_resolve_explicit): Override the orig_type value of FSI with either LRI or RLI, as determined by the first strong directional character in the isolate. This prevents failure to isolate when the FSI...PDI text is inside a directional override. (Bug#22786)

All uses changed. * eval.c (run_hook): New function. Most uses of Frun_hooks changed to use it, so that they no longer need to take the address of a Lisp sym.

(syms_of_xdisp): Defsubr it. src/dispextern.h (bidi_find_first_overridden): Add prototype. doc/lispref/display.texi (Bidirectional Display): Document 'bidi-find-overridden-directionality'. etc/NEWS: Mention 'bidi-find-overridden-directionality'.
* Minor fix in bidi.c:bidi_cache_reset_to.Eli Zaretskii2014-10-301-6/+5
| | | | | | | src/bidi.c (bidi_cache_reset_to): Invalidate bidi_cache_last_idx by setting it to -1. (bidi_find_bracket_pairs): Pass to bidi_cache_reset_to a relative index, not an absolute one, as that's what the function expects.
* A possible fix for bug #18815 with assertion violations in bidi.c.Eli Zaretskii2014-10-241-6/+16
| | | | | | src/bidi.c (bidi_resolve_explicit, bidi_find_bracket_pairs) (bidi_resolve_brackets): Use end of string position rather than ZV when iterating over a string.
* Fix bug #18778 with slow redisplay of bracketed L2R text with long lines.Eli Zaretskii2014-10-221-20/+114
| | | | | | | | | | | | | | | | | | | | src/bidi.c (bidi_cache_reset_to): New function. (bidi_cache_reset): Call it. (bidi_init_it, bidi_line_init): Initialize the bracket_pairing_pos member to -1. (bidi_resolve_explicit): Reset bracket_pairing_pos and bracket_enclosed_type only if bracket_pairing_pos's value is not ZV. (MAX_BPA_STACK): Make sure the value is signed. (PUSH_BPA_STACK): If the BPA stack overflows, don't bail out, but stop pushing values onto the stack. (bidi_find_bracket_pairs): If the bracketed text is only on the base embedding level, remove all the states cached by this function from the cache, and return zero, so that the brackets in this segment of text are processed as normal neutrals. (bidi_resolve_brackets): Detect the brackets that are to be processed as neutrals, and don't call bidi_find_bracket_pairs on them.
