- 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.

/* Bug history
|
|
*
|
|
* 2006-06-22 Carl Worth <cworth@cworth.org>
|
|
*
|
|
* This is a test case to demonstrate the following bug in the xlib backend:
|
|
*
|
|
* Some characters aren't displayed when using xlib (cache usage missing freeze/thaw)
|
|
* https://bugs.freedesktop.org/show_bug.cgi?id=6955
|
|
*
|
|
* We replicate this bug by using the cairo_scaled_font_set_max_glyphs_per_font
|
|
* function to artifically induce cache pressure. (This function was added
|
|
* for this very purpose.)
|
|
*
|
|
* 2006-06-22 Carl Worth <cworth@cworth.org>
|
|
*
|
|
* Bug was simple enough to solve by just adding a freeze/thaw pair
|
|
* around the scaled_font's glyph cache in
|
|
* _cairo_xlib_surface_show_glyphs, (I went ahead and added
|
|
* _cairo_sacled_font_freeze/thaw_cache functions for this).
