This set fixes context creation error handling. Currently if there was any error during context creation it would automatically cause segfault. There are many very small patches because they touch very different areas but any if unhandled could cause segfaulting in problematic situation. Valgrind did like this set with reduced memory leakiness (when erroring) and Waffle seems to be able now to report about which problem was met at context creation.
As an unexpected side nuance with these patches read-front clear-front-first samples=2 and read-front clear-front-first samples=4 tests in Piglit start to pass. /Juha-Pekka Juha-Pekka Heikkila (13): mesa/meta: Don't free meta if it was never initialized i965: If cache has no BO don't try to unmap BO mesa/main: Don't go freeing texture data which was never allocated mesa/main: Don't go freeing pipeline data which is not reserved mesa/program: Don't clear caches which are not allocated mesa/main: Don't free QueryObjects which were never allocated mesa/main: Don't free unallocated vertex array state mesa/main: Don't go deleting unallocated TransformFeedbackObjects mesa/main: Don't free unallocated performance monitor mesa/main: Check context pointer in _mesa_error before using it i965: Add missing return on error path mesa/main: Don't proceed on deleting null hash table mesa/main: Verify context creation on progress src/mesa/drivers/common/meta.c | 3 ++ src/mesa/drivers/dri/i965/brw_state_cache.c | 11 ++-- src/mesa/drivers/dri/i965/intel_buffer_objects.c | 1 + src/mesa/main/errors.c | 26 ++++++---- src/mesa/main/hash.c | 3 +- src/mesa/main/performance_monitor.c | 8 +-- src/mesa/main/pipelineobj.c | 9 ++-- src/mesa/main/queryobj.c | 6 ++- src/mesa/main/shared.c | 66 ++++++++++++++++++++++-- src/mesa/main/texstate.c | 13 +++-- src/mesa/main/transformfeedback.c | 12 +++-- src/mesa/main/varray.c | 6 ++- src/mesa/program/prog_cache.c | 16 +++--- 13 files changed, 137 insertions(+), 43 deletions(-) -- 1.8.5.1 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
