Behdad Esfahbod	1245395a60	[coretext] In hb_coretext_font_create() set ptem Otherwise setting the CTFont was ineffective as it would have been recreated anyway unless font size was set to 18 CSS points.	7 years ago
Behdad Esfahbod	493a005d95	[set] In add_sorted_array(), bail if data is not sorted	7 years ago
Behdad Esfahbod	a7bd6d7a4c	[collect_glyphs] Bail if input data looks like garbage Specificaly, when a range or sorted array has unexpected order, we take that as font data being garbage and bail out. This fixes significant slowdown on a bad version of Chandas font which has a 600KB GPOS with garbage inside. Later on, I like to add a maximum-work counter for collect_glyphs to protect against malicious fonts as well. Fixes https://bugs.chromium.org/p/chromium/issues/detail?id=794896	7 years ago

Behdad Esfahbod	81f27df4d9	More work towards improving collect_glyphs() against bad input The three "XXXXX"'s should be switched to false. Doing that separately for ease of bisecting...	7 years ago
Behdad Esfahbod	5d02572034	[set] Add add_sorted_array() Not optimized to use sortedness yet. Also start putting in place infra to faster reject bad data. A version of Chandas.ttf found on some Chrome bots has 660kb of GPOS, mostly junk. That is causing 48 million of set->add() calls in collect_glyphs(), which is insane. In the upcoming commits, I'll be speeding that up by optimizing add_sorted_array(), while also reducing work by rejecting out-of-sort arrays quickly and propagate the rejection.

Behdad Esfahbod	9d0194b3a8	[set] Optimize add_range() some more It's as good as it gets, and seems to be on par with previous set implementation in my benchmark. Would be great if someone can double-check my bitops.	7 years ago
