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.

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.

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.

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

Ebrahim Byagowi b143e34ee1 [gsubgpos] Initialize variation index on HB_NO_VAR 
hb_shape_plan_key_t::equal expects hb_ot_shape_plan_key_t be initialized by
hb_ot_layout_table_find_feature_variations calls but it won't get initialized
when HB_NO_VAR build config is used.
