Garret Rieger c2ee1fdd40 [subset] remove unsed table_entry struct. 2021-08-05 11:47:07 -06:00
Garret Rieger 2c024dc3cb [subset] prune redundant cmap12 subtables.
If the post subset cmap12 table is equivalent to another cmap subtable don't include the 12 table in the final subset. Matches change https://github.com/fonttools/fonttools/pull/2146 from fontTools.

Khaled Hosny 7ccc52b075 [test] Compare sha256 hash before TTX dumps
Most of time the files are identical, so instead of comparing the TTX
dump we can check sha256 hashes of the files first and if they match, we
don’t have to check the TTX dumps at all, making the subset tests orders
of magnitude faster.

time meson test --suite=subset down from:
real    0m19.418s
user    0m38.171s
sys     0m3.587s

to:
real	0m3.102s
user	0m8.622s
sys	0m1.701s

The expected files have been replaced by hb-subset output so they are
bit-identical where FontTools output might not.

The generate-expected-outputs.py now compares the hb-subset output with
fontttols subset and errors of they don’t match.

Khaled Hosny 278f44dcee [test] Speed-up subset tests by saving TTX dump
Speed-up subset tests by saving TTX dump of expected output instead of
generating it each time the tests are run.

Cuts down meson test --suite=subset on my system from:
real	0m38.977s
user	1m12.024s
sys	0m10.547s

to:
real	0m22.291s
user	0m44.548s
sys	0m9.221s

Garret Rieger b1b1486d07 [subset] update expected files to not include cmap12 pruning. 2021-03-16 14:49:35 -07:00
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.
