[Piglit] [PATCH 4/4] arb_transform_feedback2: Misc. API error checks
Ian Romanick
idr at freedesktop.org
Fri Oct 4 18:11:01 PDT 2013
From: Ian Romanick <ian.d.romanick at intel.com>
This covers most of the errors mentioned in the spec that aren't
already covered in cannot-bind-when-active.c and gen-names-only.c.
Most of the other errors should be covered by existing
EXT_transform_feedback tests.
Mesa currently passes all of these tests.
NVIDIA (304.64 on GTX 260) fails several subtests.
Pause active feedback only: Incorrectly generates error in
glEndTransformFeedback.
TransformFeedbackVaryings only when inactive: Doesn't generate any
errors when it should.
Draw only from "ended" object: Generates GL_INVALID_VALUE instead
of GL_INVALID_OPERATION.
AMD has not been tested.
v2: Convert to use piglit subtest reporting. Fix fs_only_prog to
actually only have a fragment shader attached.
v3: Quite significant re-write. Per Paul's suggestion, each of the
tests is no a subtest that can be individually selected from the command
line. This uses infrastructure in piglit-framework-gl to handle the
subtests. This also eliminates the work-around for NVIDIA's
glEndTransformFeedback-while-paused bug.
The code currently in all.tests for getting the list of subtests is
just a place holder. We'll want to refactor this out somewhere else
before pushing.
