Garret Rieger	4e2f409bce	[subset] Don't hold references to members of the active_glyph_stack. These references may get invalidated after the vector for the stack is resized. Fixes: https://oss-fuzz.com/testcase-detail/5422577634377728	3 years ago
Garret Rieger	bc899650c7	[subset] Fix for issue #3397 . cur_intersected_glyphs gets modified during recursion leading to incorrect filtering of sub tables in some cases. So don't use cur_intersected_glyphs. Instead just add an additional entry onto the parent_active_glyphs () stack. Additionaly expands NotoNastaliqUrdu tests to include coverage of the issue from #3397.	3 years ago

Behdad Esfahbod	7e160dc347	[gpos] Fix unsafe-to-break of mark-attachment This was undetected because most of the time marks were in same cluster of their base already. Fixes https://github.com/harfbuzz/harfbuzz/issues/3093	3 years ago

Garret Rieger	87496bf63e	[subset] fix fuzzer timeout if visisted_paint goes into error.	3 years ago
Garret Rieger	067f90a820	[subset] Fix for fuzzer timeout. Fixes https://oss-fuzz.com/testcase-detail/5549945449480192 In prune_langsys: move LangSys visited check up before any work is done for a LangSys. In this particular case the compare() method is responsible for the majority of the time spent and wasn't being guarded with a visisted check.	3 years ago
Garret Rieger	c4573c2ec7	[repacker] don't infinite loop if visited or roots is in error. Fixes https://oss-fuzz.com/testcase-detail/5205038086094848	3 years ago
Behdad Esfahbod	23159084b4	[morx] Reverse graphemese, not whole buffer Fixes https://github.com/harfbuzz/harfbuzz/issues/3314 Supersedes https://github.com/harfbuzz/harfbuzz/pull/3315	3 years ago
Qunxin Liu	706014f69d	[subset] (Chain)ContextSubst glyph_closure fix - When pos_glyphs is empty, use current full glyphs set as input for subsequent recursive closure process - Also increase max_lookup_visit_count to 35000 cause a real font file hit previous limit 20000 and some lookups are dropped unexpectedly	3 years ago
Qunxin Liu	51655a078e	[subset] COLR : only include glyphs after COLR closure	3 years ago
Qunxin Liu	74b46b29e7	[subset] MATH: don't serialize coverage table when iterator is empty when iterator is empty, just set coverage offset to 0. serialize() in coverage will at lease write out a 16-bit format header.	3 years ago
Khaled Hosny	6c81cd9543	[tests] Add tests for platform shapers Fixes https://github.com/harfbuzz/harfbuzz/issues/3115	3 years ago
Garret Rieger	9121ed0cec	[subset] Improve sharing of Ligature subtables. Ligature subtables use virtual links to enforce an ordering constraint between the subtables and the coverage table. Unfortunately this has the sideeffect of prevent the subtables from being shared by another Ligature with a different coverage table since object equality compares all links real and virtual. This change makes virtual links stored separately from real links and updates the equality check to only check real links. If an object is de-duped any virtual links it has are merged into the object that replaces it.	3 years ago
Garret Rieger	95329081c2	[subset] further optimize cmap4 packing.	3 years ago
Garret Rieger	599143824c	[subset] Don't pad glyphs when using long loca.	3 years ago
Garret Rieger	d9660fd58a	[subset] Make cmap4 packing more optimal. The current CMAP4 implementation uses whatever the current codepoint ranges are and then encodes them as indivudal glyph ids or as a delta if possible. However, it's often possible to save bytes by splitting up existing ranges and encoding parts of them using deltas where the cost of splitting the range is less than encoding each glyph individual.	3 years ago
Behdad Esfahbod	720ab0883b	[util] Add --single-par Use it in aots tests Fixes https://github.com/harfbuzz/harfbuzz/issues/3129 Related https://github.com/harfbuzz/harfbuzz/issues/3298	3 years ago
Qunxin Liu	903a6baece	[subset] layout_features filtering fix we should not use get_size (), which returns length * item_size	3 years ago
Khaled Hosny	69d8f27c69	[meson] Require 0.55.0 We implicitly require it for building ragel subproject. This new version requirement should satisfied in both Fedora 33 and Debian bullseye, and not be too cutting edge for us.	3 years ago
Qunxin Liu	84dc4e85e8	[subset] avoid writing out duplicate extra glyph names in post table Add check for possible duplicate with other name index	3 years ago
Qunxin Liu	ca418cac74	[subset] keep features that have FeatureParams and the tag is "size"	3 years ago
Qunxin Liu	e88fc41ef3	[subset] inputSequence could be empty, change the sanity check	3 years ago
Garret Rieger	ace98cc65f	[subset] Only sanitize recursion depth in COLR.	3 years ago
Garret Rieger	f51b48c8e7	[subset] Fix fuzzer found memory leak. Happens because an insert into a map with an invalid key reports successful, but this causes the set being inserted to be lost.	3 years ago
Qunxin Liu	540f19b6fe	[subset] fix bug in (Chain)ContextFormat2 Only keep rulesets for glyphs class numbers that survived in coverage	3 years ago
Garret Rieger	e260eeb9be	[subset] Update test goldens for gdef.glyphset.	3 years ago
Qunxin Liu	60e203644b	[subset] use glyphset_gsub instead of glyphset for GDEF	3 years ago
Garret Rieger	e39647c0f1	[subset] update subset goldens to fix tests.	3 years ago
Qunxin Liu	0a7563a53f	[subset] fuzzer fix: https://oss-fuzz.com/testcase?key=6254792024915968 Make sure input is valid, each gid has a corresponding offset value in the map	3 years ago
