Qunxin Liu 794b00db4b [subset] fuzzer fix: https://oss-fuzz.com/testcase-detail/6616166961905664 2021-09-29 10:29:06 -06:00

Garret Rieger c2cc566c9d [subset] Fix subset_offset_array adding unused space to serializer.
ArrayOf.serialize_append allocates space for the new item, but ArrayOf.pop() does not recover the allocated space. So in the case where the revert path was entered the extra space added by serialize_append gets left in the serialization buffer. This moves the snapshot to before ArrayOf.serialize_append is called so that revert cleans up the buffer extend.

Khaled Hosny c6bb719e65 [test] Add tests for Arabic decomposition
Test that both NFC and NFD input produces identical results for fonts

decompose internally (Noto Nastaliq Urdu here) and that for the former
composed forms are used.

Khaled Hosny a9dc4fbeac [test] Make shape test names match file names
No idea why test names are underscorified but it it just makes calling
meson test testname harder than it should being not able to copy file
name directly.

Garret Rieger f2441a4b65 [subset] Remove retain all layout features flag.
Instead use inverted sets to handle requesting all features. Modifies feature collection in subset plan to intersect the set of requested features against the features in the font. This prevents iterating a fully filled feature tag set.

Garret Rieger c0f3af91b8 [subset] speed up add_gid_and_children and adjust op limit.
Fix for fuzzer timeout: https://oss-fuzz.com/testcase-detail/5001604901240832.

- Operation limit is per glyph, so 100,000 should still be far more than needed.
- Switches from for(...) to while(...) loop for iteration. for(...) calls it.end() which in this case triggers a complete iteration.
- Cache CompositeGlyph size in the iterator to avoid needing to recalculate it.
