The font_face created from cairo_ft_font_face_create_for_ft_face()
was being kept alive by a reference from the context beyond the
lifetime of the parent cairo_scaled_font_t (which owned the FT_Face).
Correct the example in the test code to remove this errant reference
before cleaning up the fonts. (To be fair, to actually trigger a bug
one has to evict the FT_Face from the cache before using the font_face
- merely creating a cairo_scaled_font_t for every font on the system is
enough.)
- Remove cairo_test_expect_failure. cairo-test.c now checks
env var CAIRO_XFAIL_TESTS to see if the running test is
expected to fail. The reason for expected failure is
appended to the test description.
- Test description is written out.
- Failed/crashed tests also write a line out to stderr (in red),
so one can now redirect stdout to /dev/null to only see failures.
- cairo_test() has been changed to not take the draw function
anymore, instead, draw function is now part of the test struct.
- "make check" doesn't allow limiting backends to test using env
var anymore. To limit backends to test, one should use the
TARGETS variable on the make command line.
- "make check-valgrind" now writes its log to valgrind-log instead
of valgrind.log, to not interfere with test log file processing.
Don't call _cairo_ft_unscaled_font_init_key in the from_face case, just clear filename and id instead. Initialize unscaled->base first so that initialization order matches the structure declaration order.
Fix to accept a NULL string and hash it identically to a zero-length string.
Add a test that calls cairo_ft_font_create_for_ft_face to demonstrate bug #4110.
