From e3e13d6b857b3083e2553457fe30ddfd4eddead4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Fonseca?= Date: Sun, 1 Jun 2014 20:50:17 +0100 Subject: [PATCH] mesa: Make glGetIntegerv(GL_*_ARRAY_SIZE) return GL_BGRA. Same as b026b6bbfe3f15c8a7296ac107dc3d31f74e401e, but COLOR_ARRAY_SIZE/SECONDARY_COLOR_ARRAY_SIZE. Ideally we wouldn't munge the incoming state, so that we wouldn't need to unmunge it back on glGet*. But the array size state is copied and referred in many places, many of which couldn't take an GLenum like GL_BGRA instead of a plain integer. So just hack around on glGet*, to ensure there is no risk of introducing regressions elsewhere. This bug causes problems to Apitrace, resulting in wrong traces. See https://github.com/apitrace/apitrace/issues/261 for details. Tested with piglit arb_vertex_array_bgra-get, which was created for this purpose.
