Behdad Esfahbod d6dbc0d1 2022-06-05T00:58:53 [gi/ft] Silence warnings gi doesn't understand that FT_Face is a pointer, and not bare struct. So it skips these APIs anyway. Mark skip to silense the warning. ../src/hb-ft.cc:242: Warning: HarfBuzz: hb_ft_font_get_face: return value: Invalid non-constant return of bare structure or union; register as boxed type or (skip) ../src/hb-ft.cc:264: Warning: HarfBuzz: hb_ft_font_lock_face: return value: Invalid non-constant return of bare structure or union; register as boxed type or (skip)

Behdad Esfahbod aa3450ca 2019-06-17T22:41:49 [config] Don't compile disabled features This makes it possible to include all .cc files into build, even if not building CoreText, Uniscribe, etc. This was mostly to help custom builders. But also means that we can include all files in our own build system. Not sure if we should. Definitely simplifies things, but slightly only.

Behdad Esfahbod be2f148d 2018-10-09T16:24:50 [ft] Use mutex to lock access to FT_Face Makes our FT-backed hb_font_t safe to use from multiple threads. Still, the underlying FT_Face should NOT be used from other threads by client or other libraries. Maybe I add a lock()/unlock() public API ala PangoFT2 and cairo-ft. Maybe not.
Behdad Esfahbod d18c3c58 2018-10-09T16:07:55 [ft] Remove (probably) stale comment
Behdad Esfahbod ec84460e 2018-10-09T15:07:04 [ot/ft] Implement get_nominal_glyphs() callback Some more measurable speedup. The recent commits' speedups are as follows: Testing with Roboto, ****when disabling kern and liga****: Before: FT --features=-kern,-liga user↦ 0m0.521s OT --features=-liga,-kern user↦ 0m0.568s After: FT --features=-liga,-kern user↦ 0m0.428s OT --features=-liga,-kern user↦ 0m0.470s So, 17% speedup. Note that FT callbacks are faster than OT these days since we added an advance cache to FT. I don't think the difference is enough to justify adding a cache to OT. When not disabling kern, the thing is three times slower, so the speedups are three times less impressive... Still, 5% not bad for a codebase that I otherwise thought is optimized out. Note that, because of this and other optimiztions in our main shaper, disabling kern and liga, the OT shaper is now *faster* than the fallback shaper. So, that's my recommendation to clients that need the absolute fastest...

Behdad Esfahbod 54998bef 2018-09-11T14:35:26 [ft] Cache advances I decided to always use the cache, instead of my previous sketch direction that was to only allocate and use cache if fast advances are not available. The cache is a mere 1kb, so just use it... TODO: Invalidate cache on font size change. Fixes https://github.com/harfbuzz/harfbuzz/issues/651 Fixes https://github.com/harfbuzz/harfbuzz/pull/1082
