[tests] Enable the just added macOS test for older version 
The test is added in 7035c9cd but the same font is available in older versions of macOS
so let's run it in older versions also.

It doesn't matter much, more for consistency reasons.

Jonathan Kew 7035c9cdfe Add test for #2290. 
This tests that we can set two separate Type=Ligature selectors at the same time,
common=off + discretionary=on.

Add detail to hb_ft_font_create inline comments 
Providing lengthier explanation for how the destroy function works on the hb_font_t but that destroying the FT_Face (and not destroying it too early) remains the client's responsibility.

Qunxin Liu 0d5695983e [subset] fixes dangling object_t issue in FeatureVariationRecord 
Fixes https://crbug.com/oss-fuzz/21560
revert () does not clean up useless object_t. Adjust the order of
subsetting substitutions and conditions to avoid dangling object_t.

Ebrahim Byagowi 57b7de032f [subset] Fail ClassDefFormat1 serialization if no space available 
Fixes https://crbug.com/oss-fuzz/21580
 2020-04-05 17:38:04 +04:30
Qunxin Liu c8cc1e378d fix issues in ClassDefFormat1 serialize: 
glyph ids in Iterator may be non-consecutive,
so the number in classValue might be larger than length of the Iterator

Jonathan Kew 548a25259e Add a test for #2307. 2020-04-03 19:57:43 +04:30
Jonathan Kew 1faf0caae1 Special-case 'smcp' when checking for exposed AAT features. 
This may be implemented by selectors under either LETTER_CASE or LOWER_CASE feature types
in AAT, so we need to check for the presence of either one.

Fixes #2307.
 2020-04-03 19:57:43 +04:30
Jonathan Kew 120d86fa18 Add tests for #2305. 2020-04-03 19:20:48 +04:30
Jonathan Kew b87cf6e8d4 Fix sense of comparsion in hb_aat_map_builder_t::feature_info_t. 
This makes bsearch actually work for the features array.

Fixes #2305.

Ebrahim Byagowi 89fa70f511 [aat] minor over previous feat related changes 2020-04-03 01:08:01 +04:30
Jonathan Kew 58b4d18b53 Add a couple testcases for issue 2285. 
A few simple testcases to confirm that setting liga=0 does not break shaping with
the Tibetan AAT font Kokonor, but does still disable common ligatures in Times.
 2020-04-02 23:58:32 +04:30
Jonathan Kew b1c0b9da2f [AAT] Don't map OT tags to AAT feature types that are not exposed. 
If an AAT feature type is not exposed in the 'feat' table, we assume it is not intended
to be user-controllable and so we should not map any OT feature tag requests to it.

Fixes #2285.

Garret Rieger 014e038b2c [subset] Bail out of context lookup expansion once the lookup limit is encountered. 2020-04-01 11:14:41 +04:30
Garret Rieger 5d345d0cd1 [subset] Limit the number of lookup indices processed subsetting Feature. 
> Also, remove two unnessecary full iterations of the lookup index iterator during serialization of the index array. Fixes fuzzer found timeout.

Simon Cozens bdda2ff609 More strictly follow noun/verb/identifier format for GPOS/GSUB lookups 
Less generic than the previous commit, but more descriptive and more consistent.

Simon Cozens bef7ef81da Reformat kerx/morx instrumentation to 'verb noun identifier' 2020-03-30 16:39:43 +01:00
Simon Cozens 42aac64030 Add table index to lookup messages 
We could say GSUB/GPOS explicitly, but using the index is more general, in case future tables (such as JSTF, Silf) become supported.

Ebrahim Byagowi 18fc9197e2 [meson] Run check-symbols.sh and check-static-inits.sh correctly 
* Search src/ build directory for objects in check-static-inits.sh
* Find .def files in src/ build directory in src/check-symbols.sh
* Pass builddir also in autotools also, we may just remove libs passing after autotools removal
* Move harfbuzz_subset_def target so can be referenced as a check-static-inits.sh dependency
