Garret Rieger b8b8c58b9f [subset] add tests that check for successful repacking of a real font file. 2021-03-17 15:53:58 -07:00
Qunxin Liu 56ca435787 [subset] fix for collect_features and remove_redundant_lamngsys 
previously remove_redundant_sys () is missing in harfbuzz, after
redundant langsys removal, some features are removed as well in
prune_features() in fonttools. This change is trying to get the same
result between harfbuzz and fonttools.

Garret Rieger 190b7a98f8 [subset] Update PairPosFormat2 subsetting to match fontTools updated subsetting (https://github.com/fonttools/fonttools/pull/2221) 
- subset class def 1 against the coverage table.
- Don't re-use class 0 in class def 2.
- Ignore class 0 glyphs for the purposes of determing format 1 vs format 2 encoding for ClassDef.

Add an additional test case which demonstrates these issues.

[ot] Keep substituted Default_Ignorables (#2886) 
Don’t replace Default_Ignorables with zero-width space if they are
substituted or multiplied, not just when ligated.

After this change, HarfBuzz output matches that of Uniscribe and
CoreText for the new tests.

Behdad Esfahbod fd489433a8 [indic] Fix cluster-merging logic with cluster-level=1 
Was producing non-monotonic cluster numbers because our faulty logic
was not merging clusters if something from before base and after base
had switched positions.

Khaled Hosny 554aaa0c5d [build] Fix make distcheck 
A regression from 7b77ce0507.
It was caught by the CI build in the PR, but apparently we are now used
to CI failures that they are effectively ignored.

Also, yay for multiple build systems.

Garret Rieger f94bf9f06f [set fuzzer] limit the total number of set members in a fuzzing input. 
Currently the fuzzer can create arbitarily long inputs which once big enough will trigger a timeout.

Khaled Hosny 84dd65a874 [test] Remove timeout from test runners 
See https://github.com/harfbuzz/harfbuzz/issues/2707#issuecomment-707744079

This wasn’t inconsistent as well, HB_TEST_SUBSET_FUZZER_TIMEOUT defaulted
to 12 in the test runner, but it was overridden to 50 in meson.build,
and then meson has its own test timeout.

Simon Cozens 7c0bc0bb92 Serialize invalid buffer to !! (text) or [] (json) 
There is no generic deserialize - you have to choose glyphs or unicode - so there is no way to deserialize this buffer.

Note that now JSON glyph buffers and Unicode buffers look very similar, except for the g/u property difference.

Garret Rieger 3271a7cdaa [subset] Remove redundant langys from Amiri test font. 
FontTools removes these when subsetting but harfbuzz does not yet support redundant langsys removal. So this gets the Amiri tests passing for now.
