Garret Rieger bc06af977f [subset] speed up feature collection when tags are specified. 
Precompute a feature index filter to avoid needing to iterate the feature tag list for each encountered feature index. For this particular fuzzer case speeds up feature collection from 50s to 2s.

Khaled Hosny 14f220b761 [directwrite] Support feature ranges 
Code copied from hb-uniscribe.cc and adapted to use DirectWrite types.
May be there is a better way to de-duplicate the code, though I'm not
exactly sure how or if it is worth it.

Garret Rieger 10ad185932 [subset] add comment to copy_bytes(). 2021-06-16 17:35:39 -06:00
Garret Rieger 675ebbeb3a [subset] don't alloc zero bytes. 
It will be leaked later since hb_blob_create() won't set up the blob to cleanup since it has length zero.

Behdad Esfahbod 93e6a9bc4e Revert "Remove unneeded buffer clear_output / remove_output calls" 
This reverts commit 06175b7143.

One of the sanitizers is failing. Pushing again as PR to debug.
I have suspicions.

Behdad Esfahbod 06175b7143 Remove unneeded buffer clear_output / remove_output calls 
Made sure clear_output is always paired with swap_buffers.
Trying to see if we can move towards RAII-like buffer iterators
instead of the buffer keeping an iterator internally.

Behdad Esfahbod bdfed8f113 [blob] Add failing versions of create API 
Fixes https://github.com/harfbuzz/harfbuzz/issues/2567

New API:
+hb_blob_create_or_fail()
+hb_blob_create_from_file_or_fail()

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

Behdad Esfahbod d3dd936309 [coretext] Round position info 
Test:

Before:
$ ./hb-shape /System/Library/Fonts/ヒラギノ丸ゴ\ ProN\ W4.ttc １ --features="+palt" --shaper=coretext
[gid781=0@-78,0+841]
$ ./hb-shape /System/Library/Fonts/ヒラギノ丸ゴ\ ProN\ W4.ttc １ --features="+palt" --shaper=ot
[gid781=0@-78,0+842]

After:
$ ./hb-shape /System/Library/Fonts/ヒラギノ丸ゴ\ ProN\ W4.ttc １ --features="+palt" --shaper=coretext
[gid781=0@-78,0+842]
$ ./hb-shape /System/Library/Fonts/ヒラギノ丸ゴ\ ProN\ W4.ttc １ --features="+palt" --shaper=ot
[gid781=0@-78,0+842]

I've verified in the font that 842 is correct.

Garret Rieger 35458b6b66 [subset] Add serialize_serialize to OffsetTo. 
Similar to serialize_subset() this will serialize the new object and then link it to the offset.

From CI logs at https://github.com/harfbuzz/harfbuzz/runs/2758234200:

+ git init
hint: Using 'master' as the name for the initial branch. This default branch name
hint: is subject to change. To configure the initial branch name to use in all
hint: of your new repositories, which will suppress this warning, call:
hint:
hint: 	git config --global init.defaultBranch <name>
hint:
hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hint: 'development'. The just-created branch can be renamed via this command:
hint:
hint: 	git branch -m <name>

We want the branch too be main not master.

Peter Williams 3d48bfc187 Avoid a deprecation warning in graphite2 
As of graphite2 1.3.7, `gr_make_face` is deprecated in favor of
`gr_make_face_with_ops`. It's a one-liner to port over to using it.

This is potentially a compatibility break since I'm not sure when the
`with_ops` API was added, but the minimum version of graphite2 that's
supported by Harfbuzz doesn't seem to be documented anywhere anyway.
