Qunxin Liu 0952bc0a 2025-09-26T09:10:28 [subset] de-duplicate features (#5494)
Garret Rieger aa58b43d 2025-09-12T14:24:41 [subset] Introduce HB_SUBSET_FLAGS_RETAIN_NUM_GLYPHS. (#5547) Used in conjunction with retain gids, when set the num glyphs from the input font will be preserved. Empty glyphs will be inserted as necessary to maintain the num glyphs value. Put under experimental for now.
Garret Rieger 6dadd846 2025-09-12T18:37:30 Re-disable fonttools comparison for update_def_wght.tests
Behdad Esfahbod 0f1dab0f 2025-09-12T11:43:21 [instancer/varstore] More gain_from_merging optimization (#5543) * [instancer/varstore] More gain_from_merging optimization * [tests] Re-enable a test that was disabled until an issue fixed See comment.

Garret Rieger fac64e58 2025-05-23T18:15:41 [instancer] add a test which checks calculation of vmtx tsb during CFF2 instancing.
Garret Rieger 3e122d9d 2025-05-16T17:32:45 Disable OTS on the cmap4 overflow test case. The test file has been stripped of most tables to avoid checking in a very large font (since it has a high number of codepoints), which causes OTS to fail on missing required tables.
Garret Rieger 4e767271 2025-05-14T23:17:54 Add a test checks we can recover from cmap4 overflow.
Garret Rieger efcb7d3d 2025-04-11T23:34:06 [subset] close unicodes over bidi mirror variants during subsetting. Fixes #5281. Does the closure by default, but I've introduced a new flag and option to disable this behaviour since some users may want to get the minimal set if they know they don't need the mirrored variants.
Behdad Esfahbod e5541a0b 2025-04-05T17:02:31 [subset/test/cmap14] Reduce tested combinations Fixes https://github.com/harfbuzz/harfbuzz/issues/5254

Garret Rieger ea1434b8 2025-02-25T19:00:29 Split iup glyf partial instance tests into a separate set which ignores due to IUP rounding differences fonttools.
Behdad Esfahbod 9a0cf8d6 2025-02-25T00:19:25 [test/subset/cff-japanese] Shrink test Was taking too long.
Behdad Esfahbod 084fb3ab 2025-02-25T00:16:27 [test/subset/cmap] Shrink test Was taking more than the rest of the test suite combined.
Garret Rieger b0d52abe 2024-10-23T20:49:44 [subset] consider variation selectors subsetting cmap14 cmap14 subsetting code was not considering variation selectors in the input unicode set when deciding which variant glyphs to keep. This updates subsetting to only keeps variant glyphs if their variation selector code point is in the input unicodes set. For https://github.com/harfbuzz/harfbuzz/issues/4911

Garret Rieger 2cfa5505 2024-03-27T23:21:57 [instancer] Switch to doubles for delta calculations. FontTools uses double's internally so match FontTool's precision so we get the same results more often for floating point calculations.
Garret Rieger 990fb14d 2024-03-28T22:32:55 [subset] Disable fonttools comparison in a few tests where rounding diffs show up. Context: https://github.com/harfbuzz/harfbuzz/issues/4642

Qunxin Liu 2d001a0a 2023-11-08T11:11:51 [subset] OTS doesn't allow ligature attachment offset to be 0
Garret Rieger c6884377 2023-11-06T20:21:46 [subset] Add HB_SUBSET_FLAGS_IFTB_REQUIREMENTS flag. When enabled the output subset conforms to the requirements for a base font to be patched by IFTB patches. IFTB is a proposed incremental font transfer patch. This new flag is set as experimental. Currently, setting this flag causes the output subset to also use long offsets for outline data in loca/glyf, gvar, CFF, and CFF2. This change is a version of https://github.com/skef/harfbuzz/commit/3ae2fe2084d96f61d8ad1bbe42a6ef4e62ec830a rebased onto head w/ tests added.

Garret Rieger bbd53fcf 2023-10-10T21:41:42 Remove glyph_map test that uses retain gids. We no longer allow the use of glyph map + retain gids (see: https://github.com/harfbuzz/harfbuzz/blob/main/src/hb-subset-plan.cc#L817). Also add the test to the meson file so it will be run by default.
Qunxin Liu 6e49128a 2023-09-01T10:27:40 [instancer] always check and update default wght/width/slnt if necessary Sometimes default values in original file are incorrect, and if default value for an axis is not changed, then these values won't be updated

Garret Rieger 2175f5d0 2023-04-24T21:13:18 [subset] Fix inefficient ItemVariationStore subsetting w/ retain_gids. ItemVariationStore is relying on the assumption that the inner_map is populated for all output glyphs, this is not true for subsetting operations with retain gids enabled. Fixes fuzzer timeout: https://oss-fuzz.com/testcase-detail/4575222591520768.
Garret Rieger 3db6baa2 2023-04-17T20:01:17 [subset] add test for lig glyph fix.

Garret Rieger ddd0f7f4 2023-02-22T20:23:34 [subset] Add a test for CFF2 instancing. Adds option to disable the fonttools comparison check in the test. This is needed since CFF2 instancing is not yet supported in fonttools.
Qunxin Liu af1e605b 2023-02-10T11:08:05 [instancer] bug fix It's possible that length of all_points equals to 4 for non-empty glyphs: a composite glyph which contains only one child glyph that is empty.
Qunxin Liu 61559568 2023-01-27T11:05:13 [subset/COLR] add tests for copying varStore
Qunxin Liu 5e868703 2023-01-25T12:27:16 [instancer] compute head/maxp values using only non-empty glyphs
Qunxin Liu 27f72f0d 2023-01-24T16:08:32 [instancer] avoid double free for compiled glyph bytes also increase the HB_GLYF_MAX_POINTS limit to 20000 cause the test file has a .notdef glyph which is a composite glyph and has 10176 points after get_points() call
Garret Rieger ea1ee0d4 2023-01-14T00:23:53 [instance] drop and don't collect lookups from feature variations when fully instancing. This previously incorrectly collected lookups that could be reached via feature variations that are dropped and not activated by the current instance position.
Garret Rieger c324d999 2023-01-12T18:15:07 [instancing] Add tests for MVAR instancing.

Garret Rieger db22bfb3 2022-10-17T18:37:07 [subset] Remove Franklin from the tests which is not an open source font.
Qunxin Liu d5fc4a73 2022-09-14T14:43:20 [instance] add tests for featureVariations Also updated the script that is used to generate tests.With fonttools, we now do instancing first and then subsetting. With different order of subsetting and instancing operations on the same VF file, fonttools seems to generate 2 different font files with different glyph set. 1. do subsetting and then instancing: this seems result in a larger glyph set in the font file. Lookups are collected from both retained features and all possible alternate featurevariations, this leads to a larger glyph set after glyph closurei. And instancer doesn't redo glyph closure, it does lookups pruning only. 2. do instancing and then subsetting: lookups are collected from features that are replaced already and possible alternate feature variations
Qunxin Liu 88c02e00 2022-08-26T08:34:12 [instance] add tests for full instancing Also update previous tests with GDEF/GPOS tables

Garret Rieger 9c41bfe1 2022-06-01T17:53:14 [subset] Add subset test of font with 32 bit delta in a var store.
Qunxin Liu 7cb002cb 2022-03-14T11:40:35 [subset] bug fix in prune_langsys we should not cache visited langsys cause 2 different Record<Langsys> could have different Tag while pointing to the same Langsys, a langsys is redundant in Record<Langsys> A does not mean it's redundant in Record B. Same thing for visited_script. Also adding the number of features in the LangSys's feature list to the visited langsys count so it's more accurate. Plus some improvement in langsys compare()
Garret Rieger bc899650 2022-01-28T13:54:10 [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.
Qunxin Liu 706014f6 2021-12-01T20:20:12 [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
Qunxin Liu 51655a07 2021-12-05T19:27:57 [subset] COLR : only include glyphs after COLR closure
Qunxin Liu 74b46b29 2021-12-02T19:50:16 [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.
Qunxin Liu 903a6bae 2021-11-15T19:58:33 [subset] layout_features filtering fix we should not use get_size (), which returns length * item_size

Qunxin Liu 60e20364 2021-11-02T15:02:36 [subset] use glyphset_gsub instead of glyphset for GDEF
Qunxin Liu 364b6b39 2021-10-31T14:38:20 [subset] Don't assume FeatureList is sorted Though the spec said FeatureRecords are sorted alphabetically by feature tag, there're font files with unsorted FeatureList. And harfbuzz is not able to subset these files correctly because we use binary search in finding featureRecords when collecting lookups. Also find_duplicate_features needs to be updated to handle this.
Qunxin Liu 8c583db9 2021-10-02T20:32:30 [subset] COLRv1: update subset() method for new strutc ClipList and VarIdxMap Also fix issues in struct PaintTransform definition

Qunxin Liu 8c5c8174 2021-09-12T20:16:30 [subset] fix find_duplicate_features We should check each feature against all other features with the same tag for duplicates.
Qunxin Liu 37379f8f 2021-09-02T11:54:37 [subset] fox for (Chain)ContextFormat3: subset lookupRecord skip copying a lookupRecord if lookup referenced in the lookupRecord is not retained after subset

Garret Rieger e39c3bde 2021-08-10T11:41:55 [subset] fix bug in parsing glyf flags. the bytes of the flag stream were being treated as signed integers instead of unsigned as specified in the spec.
Garret Rieger 2c024dc3 2021-08-04T11:38:38 [subset] prune redundant cmap12 subtables. If the post subset cmap12 table is equivalent to another cmap subtable don't include the 12 table in the final subset. Matches change https://github.com/fonttools/fonttools/pull/2146 from fontTools.
