When determining the maximum number of layers we also need to take
into account GL_MAX_VERTEX_ATTRIBS on GLES2. Cogl needs one vertex
attrib for each texture unit plus two for the position and color.
This creates a material which users a layer to override the color of
the rectangle. A simple vertex shader is then created which just
emulates the fixed function pipeline. No fragment shader is
added. This demonstrates a bug where the layer state is getting
ignored when a vertex shader is in use.

Previously the alpha component of the test texture data was always set
to 255 and the data was read back as RGB so that the alpha component
is ignored. Now the alpha component is set to a generated value and
the data is read back a second time as RGBA to verify that Cogl is not
doing any premult conversions when the internal texture and target
data is the same.

The CSS Color Module 3, available at:
http://www.w3.org/TR/css3-color/
allows defining colors as:
rgb ( r, g, b )
rgba ( r, g, b, a)
along with the usual hexadecimal and named notations.
The r, g, and b channels can be:
• integers between 0 and 255
• percentages, between 0% and 100%
The alpha channel, if included using the rgba() modifier, can be a
floating point value between 0.0 and 1.0.
The ClutterColor parser should support this notation.
The Behaviour class and its implementations have been replaced by the
new animation framework API and by the constraints for layout-related
animations.
Currently, we need to make tests build, so we undef DISABLE_DEPRECATED
in specific test cases while they get ported.
The size of the texture used for test-cogl-npot-texture was only using
1 pixel of waste and the texture was scaled down so it would be quite
likely that the test would still pass if only the top left slice was
rendered. It also didn't test using non-default texture
coordinates. These problems made it fail to pick up bug 2398. The
texture is now using the maximum amount of waste and rendered in four
parts at 1:1 scale.
Previously in the tests/tools directory we build a disable-npots
library which was used as an LD_PRELOAD to trick Cogl in to thinking
there is no NPOT texture extension. This is a little awkward to use so
it seems much simpler to just define a COGL_DEBUG option to disable
npot textures.
Unparented actors are owned by the Script instance, and if that goes
away then the actors go away with it. The fact that we needed an
explicit destroy() before was a hint of a memory management issue that I
blissfully - and regretfully - ignored for the sake of a passing test
suite.
They are generated at configure time, so it's a good idea to have them
in the main ignore file instead of adding them to the built ignore files
under tests.
Re-order the units into a sensible list, with basic tests at the
beginning, and per-class tests at the end - with Cogl last.
Also, start renaming the unit functions from test_<foo> to <foo>,
so that the executable wrappers and the reports have sensible names.
The TODO() macro for adding new tests to the test suite has always meant
to be implemented like the TODO block in Test::More, i.e. a test that is
assumed to fail, and which warns if it unexpectedly succeeds.
Since GTest lacks the expressivity of Test::More, the implementation
just verifies that the tests marked as TODO actually fail, and will fail
if they happen to succeed - at which point the developer will have to
change the macro to SIMPLE or SKIP.
Even if gtester-report doesn't use that information (yet), we should
store the revision of Clutter that generated the report, and the date in
which the test suite was ran.
Instead of trying to run ./test-conformance with the -l option to
generate a list of available tests it now runs sed on the
test-conform-main.c file instead. Running the generated executable is
a pain for cross-compiling so it would be nice to avoid it unless it's
absolutely necessary. Although you could tell people who are cross
compiling to just disable the conformance tests, this seems a shame
because they could still be useful along with the wrappers for example
if the cross compile is built to a shared network folder where the
tests can be run on the actual device.
The sed script is a little more ugly than it could be because it tries
to avoid using the GNU extensions '\+' and '\|'.
The script ends up placing restrictions on the format of the C file
because the tests must all be listed on one line each. There is now a
comment to explain this. Hopefully the trade off is worth it.

Instead of calling clutter_init immediately, test-conformance now only
calls it as part of test_conform_simple_fixture_setup. The conformance
tests assert that only one test is run per instance of
test-conformance so it should never end up calling clutter_init
twice. Delaying clutter_init has the advantage that calling
"test-conformance -l" will still work even on systems with no X
server. This could be useful for automated build systems.
The keysyms defines in clutter-keysyms.h are generated from the X11 key
symbols headers by doing the equivalent of a pass of sed from XK_* to
CLUTTER_*. This might lead to namespace collisions, down the road.
Instead, we should use the CLUTTER_KEY_* namespace.
This commit includes the script, taken from GDK, that parses the X11
key symbols and generates two headers:
- clutter-keysyms.h: the default included header, with CLUTTER_KEY_*
- clutter-keysyms-compat.h: the compatibility header, with CLUTTER_*
The compat.h header file is included if CLUTTER_DISABLE_DEPRECATED is
not defined - essentially deprecating all the old key symbols.
This does not change any ABI and, assuming that an application or
library is not compiling with CLUTTER_DISABLE_DEPRECATED, the source
compatibility is still guaranteed.
This creates a 3D texture with different colors on all of the images
and renders it using a VBO to verify that the texture coordinates can
select all of the images.
This verifies that calling cogl_texture_get_data returns the same data
uploaded to the texture. The bottom quarter of the texture is replaced
using cogl_texture_set_region. It tries creating the texture with
different sizes and flags in the hope that it will hit different
texture backends.
This greatly speeds up running all the conformance tests by no longer
delaying many of the tests for a number of dummy frames to be painted.
We used to skip frames because we thought there was a problem with the
driver's glReadPixels implementation. Although we have seen driver
issues at times the real reason the delay was needed was because
resizing the stage usually happens asynchronously (because a non
synchronous X request is used by clutter_stage_set_size()). We now force
all X requests to be synchronized for the conformance tests so this is
no longer a problem and we can avoid these hacks.
This makes test-timeline get the default stage so there is at least one
stage instantiated. Without any stages the master clock will never run
which was causing this test to fail.
The report generation was broken by the split of the various test units;
also, we were using GTest in a way that's not really sanctioned by
upstream.
This commit tries to re-use the targets from GLib's Makefile rules while
compensating for our own set up.
Normally the asynchronous nature of X means that setting the clutter
stage size may really happen an indefinite amount of time later but
since the tests are so short lived and may only render a single frame
this is not an acceptable semantic.
This way we should be able to remove all the hacky sleeps and frame
count delays from our tests.
Since we now run every test in a separate process there is no need to
try and avoid state leakage between tests. This removes the code to
cleanup all children of the stage and disconnect handlers from the
stage paint signal. We now explicitly print a warning if the users tries
to run multiple tests in one process.
In the .json file used for the test, there is no null -> "base"
transition defined only a "clicked" -> "base", when the "clicked" state
is removed the "base" state will also disappear.
