Werner Lemberg 08fd250e 2017-01-09T11:30:32 [pcf] Make long family names configurable. The change from 2016-09-29 was too radical (except for people using the openSuSE GNU/Linux distribution).

Werner Lemberg 6b21d128 2016-12-30T10:00:54 [ftfuzzer] Restrict number of tested bitmap strikes. Malformed fonts often have large values for the number of bitmap strikes, and FreeType doesn't check the validity of all bitmap strikes in advance. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353 * src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'. (Random): Small class to provide n randomly selected numbers (without repitition) out of the value set [0,N]. (LLVMFuzzerTestOneInput): Use it to test only up to 10 bitmap strikes.
Werner Lemberg 7591bf11 2016-12-29T21:39:06 [truetype] Variation font API stability issues. Make some functions work before a call to `TT_Set_MM_Blend'. * src/truetype/ttgxvar.c (tt_hadvance_adjust): Exit immediately if we don't blend. (TT_Get_MM_Blend, TT_Get_Var_Design): Return default values if we don't blend.

Werner Lemberg 6fb549dd 2016-12-28T22:23:33 [psnames] Only declare, not define, data in `pstables.h' (#49949). Pdfium includes `pstables.h' a second time; moving the definition from `pstables.h' to `psmodule.c' saves more than 60kByte data segment space for this case. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist, dump_encoding, dump_array): Emit additional code to only define tables if `DEFINE_PS_TABLES' is set. * src/psnames/pstables.h: Regenerated. * src/psnames/psmodule.c (DEFINE_PS_TABLES): Define.
