This cleans the code and fixes a boolean logic error where this check
was done manually.

Avoid calling libtool to link every single test case, by building just one
binary from all the sources.
This binary is then given the task of choosing tests to run (based on user
selection and individual test requirement), forking each test into its own
process and accumulating the results.

77 is the magic exit code used by automake to indicate a skipped test, so
by using it we can get a slightly more informative test log.

Allow individuals tests to check whether a test target is enabled -
useful for those tests that circumvent cairo_test() and perform
feature testing.

In order to run under memfault, the framework is first extended to handle
running concurrent tests - i.e. multi-threading. (Not that this is a
requirement for memfault, instead it shares a common goal of storing
per-test data). To that end all the global data is moved into a per-test
context and the targets are adjusted to avoid overlap on shared, global
resources (such as output files and frame buffers). In order to preserve
the simplicity of the standard draw routines, the context is not passed
explicitly as a parameter to the routines, but is instead attached to the
cairo_t via the user_data.
For the masochist, to enable the tests to be run across multiple threads
simply set the environment variable CAIRO_TEST_NUM_THREADS to the desired
number.
In the long run, we can hope the need for memfault (runtime testing of
error paths) will be mitigated by static analysis. A promising candidate
for this task would appear to be http://hal.cs.berkeley.edu/cil/.

Vladimir Vukicevic reported that surfaces were being created with
mismatching Visuals and XRenderPictFormats - and demonstated here.

As we only use RGB24 surface data the alpha channel is undefined, so
zero it to prevent valgrind warnings.

Fixup the headers and boilerplate to compile and run correctly when
configured with --disable-xlib-xrender.

Without this, any tests that were using cairo_test_init rather than
cairo_test would end up leaking a FILE* for the log file. So this
keeps valgrind much more happy with the test suite.

In a manner similar to flattening in advance, we now extract the sub-
surface of interest (when testing with device offsets) before calling
into the buffer_diff functions. This allows these functions to accept
a single stride value once again instead of one for each of the three
images.

The interface of the various buffer/image_diff functions is improved to
provide the maximum pixel difference in addition to the number of pixels
that differ. This value can then be used to compare against a per-backend
tolerance.
Currently I've set the SVG backend's tolerance to 1 to handle some issues
we're currently seeing of single-bit differences on different systems, (but
we're not exactly sure why yet).
Also I improved the image_diff routines to properly report a status value
on failure rather than the bogus value of -1 for pixels_changed.

- 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.

When accessing the underlying drawable etc of an xlib surface, it is
also helpful to be able to get the width and height without a server
round trip. This patch provides those functions.

This patch was produced with the following (GNU) sed script:
sed -i -r -e 's/^[ \t]+$//'
run on all *.[ch] files within cairo.

[With this change, two tests with gradients exhibit subtle differences

though. -cworth]

New function to reset all static data (eg. caches) to their initial state.
Fix check-valgrind target to depend on the 'all' target.
Add check for a new, proposed, XrmFinalize function.
Add cairo-debug.c.
Move the definition of CAIRO_BEGIN_DECLS to cairo-features.h so that it can be shared between public header files, and so that it doesn't clutter cairo.h
Implement reset_static_data in all modules as required.
Call cairo_debug_reset_static_data and FcFini so that we can have all tests be valgrind-clean with respect to memory leaks and still-reachable data.

argument.
Track change in _cairo_pattern_release_surface and also pass the appropriate pattern for each acquired surface. The previous backend mismatch was causing memory leaks.
Remove stale comment.
Add missing fclose to keep valgrind happy about memory leaks.

Add cairo_xlib_surface_create_with_render_format.
Reduce Xlib constructors down to two simple forms. Add width, height to constructors and eliminate any synchronous size queries from the implementation.
Update to match new cairo_xlib_surface_t create functions.
|
| | |
|
|
|
Drop the _for_pixmap() and _for_window() out of the create functions and use some lazy cleverness to sniff the information out as needed.
src/cairo-xlib-surface.c src/cairo-xlib-test.h Makefile.am: add cairo_test_xlib_disable_render() to turn off RENDER for tests.
Test various different types of Xlib surface creation.
Remove left-over include of Xrender.h.
