Garret Rieger f9d8e4a976 [subset] switch ..._set_flags to not take a mask. 2021-07-29 18:30:27 -07:00
Garret Rieger 3d534b146c [subset] convert subset input flags into bit flags.
Store the flags in a bit set. Updates the public api to work with the bit set directly.

Khaled Hosny 895162d6f3 [test] Account for mark zeroing in AOTS tests
The AOTS are not written with the face that mark glyphs gets their
advances zeroed. Taking this into account makes 16 more tests to pass.

Khaled Hosny e65bf60500 [test] make this test runner less verbose
Print the command being called once and in a way the can be manually
run.

Khaled Hosny ddf87ffb22 [test] Add generated tests for emoji clusters
Fixes https://github.com/harfbuzz/harfbuzz/issues/3017

Uses AdobeBlank2.ttf from:

  https://github.com/adobe-fonts/adobe-blank-2

instead of a dummy empty font so that everything maps to GID 1 and
control code points are kept instead of being dropped because there is
not space glyph (otherwise we’d need to identify control code points
somehow when generating the expectations).

Garret Rieger acbd8b27dc [subset] temporarily disable COLRv1 subsetting.
Currently COLRv1 spec is being changed so the subsetting implementation is out of sync. Disable subsetting by failing sanitization for COLRv1 tables and disable all colrv1 tests.

Khaled Hosny c65e1e0842 [test] Run AOTS cmap tests with ot font functions only
We are not interested in testing FreeType cmap support.

Fixes most format 4 tests. The remaining test seems to be peculiar, and
I can’t find any cmap implementation that produces the expected output.

Khaled Hosny 8396c523b6 [test] Add AOTS cmap tests
Uses https://github.com/adobe-type-tools/aots/pull/3

Related to https://github.com/unicode-org/text-rendering-tests/issues/70

We don’t support format 4 or 8, so these tests are disabled. We support
format 4 but most of the tests are failing, investigating.

Khaled Hosny 50379fbb15 [util] Don’t split text at new lines in batch mode
In batch mode (which is used for testing) we are probably not interested
in splitting text into lines as we could have split the string into
different tests. This fixes a bunch of AOTS tests that use newlines as
input.

Khaled Hosny 92b85749f2 [util] Strip quotes when parsing features
When running in batch mode, the quotes are not stripped by the shell and
end up in the feature string. This breaks one of the AOTS tests.

Alternatively, we can remove the quotes from the test files, not sure
which is less hacky, though!

Use these in util/ to distinguish empty file from not-found file.
Only err on the latter.
