Behdad Esfahbod 03085132 2022-03-21T18:06:33 [buffer] Fix out-buffer under memory-alloc failure This was broken in July refactoring of the buffer, and exposed to ReverseChainSingleSubstFormat1 in 3807061d634b60bd6235d6e1d8c47a034377f924 Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=38800 https://bugs.chromium.org/p/chromium/issues/detail?id=1303552

Behdad Esfahbod da500568 2021-10-26T08:02:29 [API] Add hb_buffer_[sg]et_not_found_glyph() and --not-found-glyph Instead of using gid=0 when a character is not found in the font, client can now set a custom value. This is useful for shaper-driven font fallback and to differentiate that from .notdef glyph. Fixes https://github.com/harfbuzz/harfbuzz/issues/1360
Behdad Esfahbod 4b5a81f1 2021-08-25T15:20:54 [buffer] Fix hb_buffer_append() pre/post-context logic Part of https://github.com/harfbuzz/harfbuzz/pull/3150

Behdad Esfahbod 3e266e5f 2021-07-12T17:30:26 [buffer] Update comments
Behdad Esfahbod 3807061d 2021-07-12T17:02:03 [ot-layout] Don't remove_output() before reverse substitution No need anymore, because of new swap_buffers() semantics. Just assert instead.
Behdad Esfahbod 10a9960f 2021-07-12T17:09:03 [buffer] Restructure swap_buffers() Is more of a "commit" operation now. Will rename when ready.
Behdad Esfahbod 05c17787 2021-07-12T16:55:08 [buffer] Rewind cursor in clear_output()
Behdad Esfahbod 69310f14 2021-07-09T17:24:29 [buffer] Change nil buffer have_output to false Seems like a historical artefact that it was true.
Behdad Esfahbod 2337f0d0 2021-07-08T10:58:50 Internally use hb_malloc/.../hb_free instead of malloc/.../free Redefining those stock names as macros was conflicting with gcc 10 headers. Fixes https://github.com/harfbuzz/harfbuzz/issues/3044
Behdad Esfahbod 93e6a9bc 2021-06-15T15:38:49 Revert "Remove unneeded buffer clear_output / remove_output calls" This reverts commit 06175b71433bc42edc07d342e6354035e37fb5fd. One of the sanitizers is failing. Pushing again as PR to debug. I have suspicions.
Behdad Esfahbod 06175b71 2021-06-15T14:33:27 Remove unneeded buffer clear_output / remove_output calls Made sure clear_output is always paired with swap_buffers. Trying to see if we can move towards RAII-like buffer iterators instead of the buffer keeping an iterator internally.
Behdad Esfahbod c61ce962 2021-06-10T17:33:29 [buffer] In hb_buffer_get_positions(), return NULL if inside message callback As discussed in https://github.com/harfbuzz/harfbuzz/issues/2468#issuecomment-645666066 Part of fixing https://github.com/harfbuzz/harfbuzz/issues/2468
Behdad Esfahbod 34a1204f 2021-03-15T14:39:06 [buffer] HB_NODISCARD output_glyph() Also, generalize and use replace_glyphs() in morx where output_glyph() was used in a loop.
Behdad Esfahbod b05e5d9a 2021-03-15T14:08:08 [buffer] HB_NODISCARD next_glyphs()
Behdad Esfahbod 05d2d37f 2021-03-15T13:43:29 [buffer] HB_NODISCARD ensure()
Behdad Esfahbod 906c9928 2021-03-15T13:13:45 [buffer] Return success status from buffer ops that can fail Previous error-handling philosophy was that user doesn't need to immediately know whether operation failed. But as can be seen after we added malloc-failing fuzzing, there's just so many places in the code that a failure of these operations needs to be mitigated before further operations. So I'm moving towards returning success here, and possibly making it nodiscard.
Behdad Esfahbod 2d39031f 2020-06-28T20:48:48 [buffer/set/map] Move immutable check only to C API boundary The immutable objects are a concept only enforced by the C API. So move checks only to that region. This does assume that the rest of the code is careful not getting into these internal methods on immutable objects, which something we do, but have no way of enforcing (currently). .

Garret Rieger 14a7b6f1 2020-02-26T15:09:04 Set hb_buffer_t to use array_t.reverse().
Evgeniy Reizner b79ceac3 2019-12-15T16:50:01 Prefer UINT_MAX instead of uint overflow. Also, prefer HB_FEATURE_GLOBAL_START and HB_FEATURE_GLOBAL_END.
Evgeniy Reizner b618e0ae 2019-12-15T16:26:50 Remove non-breaking spaces from comments. `0xC2A0` was used, for some reasons. It's not really a problem, but Qt Creator constatly trying to replace them with regular spaces, so I have to edit those files separately.
Evgeniy Reizner 780d640c 2019-12-15T16:11:37 Remove unnecessary check in hb_buffer_t::set_masks. Bounds are already checked by the caller. Closes #2073

David Corbett a03f5f4d 2017-12-28T22:59:29 Replace "ISO 639" with "BCP 47" `hb_language_from_string` accepts not only ISO 639 but also BCP 47. Not all ISO 639 codes are valid BCP 47 tags but the function does not accept overlong language subtags anyway.
Behdad Esfahbod e42cd58c 2018-10-07T20:46:11 Rename invisible_codepoint to invisible_glyph in API Deleted recently added API: hb_buffer_set_invisible_codepoint() hb_buffer_get_invisible_codepoint() hb-shape / hb-view --invisible-codepoint New API: hb_buffer_set_invisible_glyph() hb_buffer_get_invisible_glyph() hb-shape / hb-view --invisible-glyph Fixes https://github.com/harfbuzz/harfbuzz/issues/1216

Behdad Esfahbod 55bae682 2018-09-24T10:43:06 [docs] A few improvements If we wrote just this much every day...
Behdad Esfahbod 606bf574 2018-09-16T19:33:48 Revert forcing use of single-parameter static_assert() Some clang versions define static_assert as a macro apparently, so we cannot redefine it... This reverts commit 94bfea0ce6a7b4d5641c198d50751748a353df11. This reverts commit 4e62627831e7457ed60ff87712570065b14b200a.
Behdad Esfahbod 4e626278 2018-09-16T18:09:36 Enforce single-param static_assert() only So we don't accidentally break it again.
Behdad Esfahbod c77ae408 2018-08-25T22:36:36 Rename hb-*private.hh to hb-*.hh Sorry for the noise, downstream custom builders. Please adjust.
Behdad Esfahbod f0ef096b 2018-08-13T10:30:41 Don't add reference in get_unicode_funcs() functions Users don't expect a new reference returned from a get() function. Indeed, all users of that API I foud where NOT destroying the reference. Just change the implementations to NOT return a reference. This applies to the following APIs: hb_unicode_funcs_get_default() hb_glib_get_unicode_funcs() hb_icu_get_unicode_funcs() Fixes https://github.com/harfbuzz/harfbuzz/issues/1134
Behdad Esfahbod 3506672c 2018-08-06T06:17:48 Port _nil objects to Null() machinery Finally, unified!
Behdad Esfahbod bddeb2b1 2018-07-10T14:12:37 Minor renamings of internal inline functions
Behdad Esfahbod 7185b273 2018-05-31T20:03:00 Rename in_error to !successful Towards possibly using Null pool for some nil objects.
Behdad Esfahbod f673cfbd 2018-05-07T13:58:32 Support scripts that are written both LTR and RTL Right now only Old Italic is marked as such. Fixes https://github.com/harfbuzz/harfbuzz/issues/1000
Behdad Esfahbod cc1e0840 2018-02-06T10:20:48 [buffer] Tweak diff re glyph_flags again We expect the buffer to have no flags that the reference doesn't... Meh. Makes MORX tests pass now. Need to better define the behavior.
Ebrahim Byagowi d49ae515 2018-02-06T13:48:10 Fix hb-buffer logic error
Behdad Esfahbod 54e6efad 2018-02-04T14:58:02 [aat] Fix unsafe-to-break At any position, if state is not zero, mark unsafe-to-break before, unless we can reason it safe. At any position, if there's an action entry for end-of-text, mark unsafe to break. Also changes buffer diff impl to allow for flag differences as long as the buffer glyph flags are superset of reference glyph flags. With this, all MORX tests pass.
Behdad Esfahbod baf7779d 2017-11-14T21:53:48 Limit how much recursion GSUB/GPOS does This only counts recursions right now. Good start. Hopefully... Fixes https://github.com/behdad/harfbuzz/issues/429

Behdad Esfahbod c3448e8d 2017-10-15T12:02:00 Use static_assert instead of custom ASSERT_STATIC
Behdad Esfahbod d03f11f2 2017-09-04T20:14:13 Fix buffer_diff for empty buffers If buffers are empty, content type should be ignored. This fixes last of the failing tests: fuzzed.tests. Green again!
Behdad Esfahbod 099472e0 2017-08-30T16:45:06 hb_buffer_diff() tweak I like to have a mode where CONTAINS_NOTDEF and CONTAINS_DOTTEDCIRCLE are not returned. Abused a value of -1 for that. hb-shape now uses it. Fixes two of the six tests failing with --verify in test/shaping/run-tests.sh.
