Behdad Esfahbod 6c4bb60829 Fix narrowing errors with recent changes 2021-02-22 23:05:55 -07:00
Behdad Esfahbod f4f35a4d5f [constexpr] Use initializer instead of assignment 2021-02-22 22:32:42 -07:00
Behdad Esfahbod 6a3fd94f3b
Merge pull request #2699 from googlefonts/gpos_8 
[subset] Add a more complex layout subsetting test case and fix the issues it exposed.
 2021-02-09 20:49:04 -05:00
Behdad Esfahbod ca0b7afee9 [set] Use hb_fill() 2021-01-21 12:22:00 -07:00
Behdad Esfahbod 6463ee02d6 Speed up ClassDef/Coverage intersect methods 
Just avoiding overhead as measured by Garret.
Should rewrite as dagger in the future and confirm that it has the
same benefits. Later on, rewrite as lfind() maybe.

Fixes https://github.com/harfbuzz/harfbuzz/issues/2826
 2021-01-21 11:16:04 -08:00
Garret Rieger e583505334 [subset] Use plan->glyphset_gsub instead of plan->glyphset for GSUB/GPOS 
This matches fontTools behaviour. glyphset_gsub does not contain gids added from closing over composite glyphs in glyf, since these cannot particpate in GSUB/GPOS processing.
 2020-09-29 11:16:15 -07:00
Garret Rieger 9825e3dd2e [ENOMEM] fix access to unitialized memory. 
If the serialize() call fails to write the object then we can't safely read varstore_prime fields. Fixes https://oss-fuzz.com/testcase-detail/5137462782066688.

Jonathan Kew e5d6fe9782 Don't skip setting the .end field of the first range 
Fixes a bug in CoverageFormat2::serialize whereby the first range
was not serialized correctly if it consists of only a single glyph ID.
This broke shaping of U+0626 in the Arabic fallback shaper, because it
is not found in the coverage table of the 'init' and 'medi' lookups.

Also fix similar bug in ClassDefFormat2::serialize, noted during code
inspection (I haven't observed a case that was actually affected by
this, but it looks broken).

Behdad Esfahbod 7987095e64 [meta] Remove hb_enable_if_t 
It was only used for C++<11 which does not allow default parameters
in function templates.  Looks like we cannot support <11 anyway, so,
start cleaning up.

hb_name_id_t
HB_NAME_ID_INVALID
 2018-10-12 16:06:39 -04:00
Ebrahim Byagowi dc49bd8d81 Add two APIs for getting stylistic set labels 
* hb_ot_layout_feature_get_characters
* hb_ot_layout_feature_get_name_ids

However HarfBuzz currently doesn't expose an API for retrieving the actual
information associated with NameId from the `name` table and that should be
done separately.

Behdad Esfahbod 10642b3fbf Disallow null-enabled offsets to unsized structures... 
...like UnsizedArrayOf<>.

This fixes a class of crasher bugs, mostly with color and AAT tables.  We
cannot use nullable offsets to varsized data that does not declare min_size,
because it's nost safe to use our fixed-size null pool for types that have
their size external.  So, use non_null'able offsets for these.

A further enhancement would be to make use of min_size in Null<> itself.
Will try that after.
