Behdad Esfahbod	04fd8517f8	Add tests for hyphen fallback U+2011 is <noBreak> equivaent of U+2010, so we should do the fallback for it. Currently fails.	9 years ago
Behdad Esfahbod	550417117d	[test] Drop hintings when subsetting fonts to record	9 years ago
Behdad Esfahbod	49ef630936	Adjust the width of various spaces if font does not cover them See discussion here: `81ef4f407d` There's no way to disable this fallback, but I don't think it would be needed. Let's hope for the best! Fixes https://github.com/behdad/harfbuzz/issues/153	9 years ago
Behdad Esfahbod	aa7044de0c	Generalize flags types	9 years ago
Behdad Esfahbod	7793aad946	Normalize various spaces to space if font doesn't support This resurrects the space fallback feature, after I disabled the compatibility decomposition. Now I can release HarfBuzz again without breaking Pango! It also remembers which space character it was, such that later on we can approximate the width of this particular space character. That part is not implemented yet. We normalize all GC=Zs chars except for U+1680 OGHA SPACE MARK, which is better left alone.	9 years ago

Behdad Esfahbod	4cc80bed25	Fix typo! Ouch! Fortunately that function was unused.	9 years ago

Behdad Esfahbod	df698f3299	[ot-font] Fix hmtx table length checking, again Exactly the same problem that I fixed in `63ef0b41dc` I rewrote the table checking yesterday in `67f8821fb2` and introduced the exact same issue again. :( Good thing we have ongoing fuzzing going now. Was discovered immediately by libFuzzer. Thanks kcc! https://github.com/behdad/harfbuzz/issues/139#issuecomment-153449473 Fixes https://github.com/behdad/harfbuzz/issues/156	9 years ago
Behdad Esfahbod	3530cc2d7c	[util] Fix option-parsing leaks	9 years ago
Behdad Esfahbod	642135f3b2	[util] In --debug mode, duplicate font data This has the effect that the font data will end up in a memory section malloc()ed exactly to its size. This gives us better valgrind detection of out-of-bounds access. Previously, the font data was placed in a mmap()ed section or GString-allocated area, which didn't have proper protections at the end when running under valgrind.	9 years ago
Behdad Esfahbod	ed2024ef93	[perf] Micro-optimize	9 years ago
Behdad Esfahbod	76a5310a83	Remove irrelevant comment I tried moving the is_default_ignorable() function to an INTERNAL function. That made the binary size grow by 5k AND things got a tad bit slower!	9 years ago
Behdad Esfahbod	8259669fbd	Minor	9 years ago
Behdad Esfahbod	9382c471ea	Combine unicode_props0/1 into a uint16 Slightly faster. In prep for more changes.	9 years ago

Behdad Esfahbod	67f8821fb2	[ot] Make bad-hmtx handling match FreeType Also route fuzzing-related tests through hb-ot-font, to reduce dependency on FreeType behavior for badly-broken fonts. Fixes failing test with FreeType master.	9 years ago

Behdad Esfahbod	ca97ea7aa2	[ft] Revert change-of-behavior of hb_ft_font_create() introduced in 1.0.5 The default FreeType load flags where changed from FT_LOAD_NO_HINTING to FT_LOAD_DEFAULT in `2a9627c564`. This is crashing HarfBuzz-enabled FreeType as I suppose it causes infinite recursion between HB and FT autohinter... Revert the behavior change.

Behdad Esfahbod	613e630617	Reduce max nesting level from 8 to 6 We probably should implement better system to catch cyclic lookups. But for now, this speeds up worst case behavior with broken fonts considerably without compromising legitimate usecases. https://github.com/behdad/harfbuzz/issues/139#issuecomment-147788447	9 years ago
