Behdad Esfahbod 1da7423ed9 [array] Add constructor taking std::nullptr_t 
Not all impls implement nullptr_t in a way that would automatically
convert to what we were accepting.

In file included from ../src/test-map.cc:27:
../src/hb-map.hh:44:22: error: no viable conversion from 'nullptr_t' to 'const hb_array_t<const char>'
  static constexpr K INVALID_KEY   = kINVALID;

Behdad Esfahbod 394f772937 [map] Allow storing classes in the hashmap 
Fixes https://github.com/harfbuzz/harfbuzz/issues/3293

The trick was to change the type of the invalid key/value to be non-class.

Matthias Clasen 1fd7fd9823 Cosmetics: Avoid confusing indentation 
This line had me confused for a second because
the condition looked like a cast and the if just
looked misplaced. Add a line break to prevent
such confusion.

Matthias Clasen 3471f8f69e docs: Clarify a doc comment 
Reword the docs for hb_ot_layout_script_select_language and
be a bit more specific about the returned index.

Behdad Esfahbod 07dc34bdaf [mutex] Try work around GCC cast-align error/warning

Garret Rieger f51b48c8e7 [subset] Fix fuzzer found memory leak. 
Happens because an insert into a map with an invalid key reports successful, but this causes the set being inserted to be lost.

Qunxin Liu 0a7563a53f [subset] fuzzer fix: https://oss-fuzz.com/testcase?key=6254792024915968 
Make sure input is valid, each gid has a corresponding offset value in
the map

Qunxin Liu 364b6b3989 [subset] Don't assume FeatureList is sorted 
Though the spec said FeatureRecords are sorted alphabetically by feature
tag, there're font files with unsorted FeatureList. And harfbuzz is not
able to subset these files correctly because we use binary search in
finding featureRecords when collecting lookups. Also
find_duplicate_features needs to be updated to handle this.

Garret Rieger 49c9392412 [subset] During LigatureSubstFormat1 subsetting always place Coverage last. 
In Windows 7 on Chrome if the coverage table comes before any of the LigatureSet or Ligature subtables the font won't load. This changes the packing order to always place the Coverage table last. Virtual links are used to ensure the repacker maintains the desired ordering.

Coincidentally fontTools also does the same thing (a3f988fbf6/Lib/fontTools/ttLib/tables/otTables.py (L1137)) to reduce overflows during packing.

Garret Rieger 5bfc7d1015 [repacker] remove VirtualOffset struct. 
Make and add_virtual_link () specialization of add_link() instead.

Garret Rieger bc4c5341d6 [repacker] Add test for virtual links in the repacker. 2021-11-02 12:19:13 -06:00
Garret Rieger 7615b94ecf [repacker] add 'virtual links' to the serializer. 
These aren't associated with an offset field, but instead exist solely to add an ordering constraint to the object graph.
