	12ec6682	2025-09-02T14:21:57		[buffer] Micro-optimize set_masks Somehow this specialization loop was in HarfRust / RustyBuzz.
	598da8c8	2025-09-02T14:21:08		[buffer] Add some buffer op accounting to a few methods (#5522) Should fix a fuzzer-found issue, now that we have increased most buffer limits.
	6c42e2d7	2025-08-21T00:04:56		[buffer] Consume ops in shift_forward (#5488) Makes failing infinite-recursion fonts and stuff much faster.
	b51de936	2025-08-20T23:15:46		Remove duplicate buffer->leave call (#5487) * Remove duplicate buffer->leave call hb-shape.cc does it for us. * Fail shaping if max len reached * Increase buffer limits https://github.com/harfbuzz/harfrust/issues/107 * Remove shaping_failed; fail in buffer.successful

	094f8073	2022-11-23T22:03:26		[buffer] Handle null buffer in set_message_func
	404cb99d	2022-11-23T15:35:14		[buffer-diff] Fix check for glyph flag equality I'm not sure if the old behavior was intentional, but it was checking that the glyph flags were a subset of the reference buffer's glyph flags. I don't see why that is useful. Fix that. Then make the buffer-verify code ignore flag differences when verifying buffers, since our unsafe-to-concat flag at least, is conservative and not guaranteed to be produced the same in fragments. See: https://github.com/harfbuzz/harfbuzz/issues/3888
	59c45f6d	2022-11-22T12:54:50		Use hb_memcpy instead of memcpy consistently

	1945b400	2022-07-25T10:45:55		[cpluscplus] Wrap hb-subset types as well Also changes signature of get_user_data of hb.h types to take const object. This is safe.
	0722b627	2022-07-24T17:35:44		[buffer] Return delta from sync_so_far
	c55c0197	2022-03-21T19:11:17		[buffer] Add assertions of buffer sync status to message_impl
	da9edce8	2022-03-21T18:51:01		[buffer] Add sync_so_far() This removes separate out-buffer, at the cost of possibly changing idx.
	98e90cc6	2022-06-30T08:43:57		[docs] Reduce warnings Use markdown syntax for inline code blocks instead of %true, %false, and %NULL.
	689c7753	2022-06-10T07:37:45		[buffer] Actually remove TODO item In reality, one side is smaller and one side is larger. The existing code handles that just fine.

	f78a2509	2022-06-05T00:55:35		[gi] Remove Xconstructor annotations
	55b911d8	2022-06-01T08:13:06		[buffer] Mark getter functions as taking const buffer Fixes https://github.com/harfbuzz/harfbuzz/issues/2873

	f7f61aeb	2022-05-31T09:37:38		[buffer] Add TODO item
	9a2a8570	2022-05-31T04:25:20		[ot-shape] Don't verify buffer if shaping failed Fixes all of fuzzing verify failures, which were result of buffer failure on super-long results, which fails unsafe-to-break because shorter strings don't fail shaping.
	2e186d9f	2022-05-20T13:15:52		[buffer] Improve hash function of segment_properties_t
	d35c73cd	2022-03-22T10:20:28		[buffer] Whitespace
	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

	f643b81f	2022-01-03T11:45:31		[buffer] Clean up internal state bookkeeping hb_buffer_reset() was NOT resetting cluster_level. Ouch! Fix that. Part of https://github.com/harfbuzz/harfbuzz/issues/1555
	36e9f467	2022-01-03T11:23:14		[buffer] Overlay segment-properties in hb_buffer_append() Part of https://github.com/harfbuzz/harfbuzz/issues/1555

	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
	4b5a81f1	2021-08-25T15:20:54		[buffer] Fix hb_buffer_append() pre/post-context logic Part of https://github.com/harfbuzz/harfbuzz/pull/3150

	09c3b82f	2021-07-29T17:49:10		[buffer] When shifting forward, leave no gap Trying to see if this fixes the fuzzer issue: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=36236
	3e266e5f	2021-07-12T17:30:26		[buffer] Update comments
	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.
	10a9960f	2021-07-12T17:09:03		[buffer] Restructure swap_buffers() Is more of a "commit" operation now. Will rename when ready.
	05c17787	2021-07-12T16:55:08		[buffer] Rewind cursor in clear_output()
	69310f14	2021-07-09T17:24:29		[buffer] Change nil buffer have_output to false Seems like a historical artefact that it was true.
	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
	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.
	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.
	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
	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.
	b05e5d9a	2021-03-15T14:08:08		[buffer] HB_NODISCARD next_glyphs()
	05d2d37f	2021-03-15T13:43:29		[buffer] HB_NODISCARD ensure()
	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.
	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). .
	21433fa5	2020-06-28T20:46:02		m[buffer] In hb_buffer_append() don't change until allocation success
	3b91e0b5	2020-06-28T20:33:54		m[buffer] Rename internal variable
	9fcba109	2020-06-28T20:30:39		[buffer] Make swap_buffers() copy rest
	9936490c	2020-12-31T00:19:29		[docs] Invalid use of "optional" annotation It is valid only for out and inout parameters. Fixes https://github.com/harfbuzz/harfbuzz/issues/1787
	2fdab788	2020-12-30T23:44:30		[docs] Complete hb-buffer docs a bit
	cb319f0d	2020-12-24T21:47:05		[docs] Add some missing annotations to hb-buffer.cc
	f88e845f	2020-12-24T21:28:37		[docs] Minor fixes
	e8de26e1	2019-04-21T20:31:54		[docs] Add gtkdoc comments to hb-buffer

	77e704d1	2020-10-15T02:02:04		[buffer] Add assert_unicode()/assert_glyphs() and use internally
	3232e6f2	2020-10-15T00:20:17		[buffer] Add hb_buffer_has_positions() Fixes https://github.com/harfbuzz/harfbuzz/issues/2716
	48ad7459	2020-07-29T08:09:08		[ENOMEM] Fix buffer's content check logic So now rest of shape fuzzer also can be enabled. Fixes #2571
	d0e2addd	2020-07-18T22:14:52		minor
	2dda6dd7	2020-04-20T14:12:45		minor, tweak spacing turn 8 spaces to tab, add space before Null/Crap
	14a7b6f1	2020-02-26T15:09:04		Set hb_buffer_t to use array_t.reverse().
	b79ceac3	2019-12-15T16:50:01		Prefer UINT_MAX instead of uint overflow. Also, prefer HB_FEATURE_GLOBAL_START and HB_FEATURE_GLOBAL_END.
	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.
	780d640c	2019-12-15T16:11:37		Remove unnecessary check in hb_buffer_t::set_masks. Bounds are already checked by the caller. Closes #2073
	5fddc5f1	2019-11-20T13:07:26		Use foreach_cluster
	029775bc	2019-10-09T11:00:09		[buffer] Minor; improve HB_NO_BUFFER_MESSAGE
	670fec23	2019-10-10T09:21:08		Minor, add a zero length tolerant memset, hb_memset
