Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...
This reverts commit 94bfea0ce6.
This reverts commit 4e62627831.
Users don't expect a new reference returned from a get() function.
Indeed, all users of that API I foud where NOT destroying the reference.
Just change the implementations to NOT return a reference.
This applies to the following APIs:
hb_unicode_funcs_get_default()
hb_glib_get_unicode_funcs()
hb_icu_get_unicode_funcs()
Fixes https://github.com/harfbuzz/harfbuzz/issues/1134
At any position, if state is not zero, mark unsafe-to-break before,
unless we can reason it safe.
At any position, if there's an action entry for end-of-text, mark
unsafe to break.
Also changes buffer diff impl to allow for flag differences as long
as the buffer glyph flags are superset of reference glyph flags.
With this, all MORX tests pass.
I like to have a mode where CONTAINS_NOTDEF and CONTAINS_DOTTEDCIRCLE are not
returned. Abused a value of -1 for that. hb-shape now uses it. Fixes two
of the six tests failing with --verify in test/shaping/run-tests.sh.
Change hb_buffer_diff to explicitly cast result of abs to unsigned when
comparing with position_fuzz to avoid unsafe signed/unsigned comparions
warnings on windows.
We break and shape fragments and reconstruct shape result from them.
Remains to compare to original buffer. Going to add some buffer
comparison API and use here, instead of open-coding.
We were relying on cluster merges not requiring unsafe flagging because
they get merged. If cluster level requests no merging, then we flag
unsafe when merge would have happened.
API changes:
- If NDEBUG is defined, define HB_NDEBUG
- Disable costlier sanity checks if HB_NDEBUG is defined.
In 1.2.3 introduced some code to disable costly sanity checks if
NDEBUG is defined. NDEBUG, however, disables all assert()s as
well. With HB_NDEBUG, one can disable costlier checks but keep
assert()s.
I'll probably add a way to define HB_NDEBUG automatically in
release tarballs. But for now, production systems that do NOT
define NDEBUG, are encouraged to define HB_NDEBUG for our build.

Right now we cannot test this because it has to be tested using hb-fuzzer.
We should move all fuzzing tests from test/shaping/tests/fuzzed.tests to
test/fuzzing/ and have its own test runner. At that point, should add
test from this issue as well.
Currently just announces lookup applications. Message-API *will* change.
hb-shape / hb-view are updated to print-out messages to stder if --debug
is specified.
