From cd02f60c1e9d0ef37e4defb8e6b00433990fd90c Mon Sep 17 00:00:00 2001 From: Pierre-Eric Pelloux-Prayer Date: Tue, 23 Jul 2019 16:39:31 -0700 Subject: mesa: Fix GetTextureImage error reporting, again Iago Toral Quiroga fixed this in commit 94f740e3fce0cb26e4d90cb9de75b, but it recently regressed in 0d8826f723cd8868b5271f17f18a1ab4548a1199. Quoting Iago's original commit message for the fix: GetTex*Image should return INVALID_ENUM if target is not valid, however, GetTextureImage does not receive a target, and instead should return INVALID_OPERATION if the effective target is not valid. From the OpenGL 4.6 core profile spec, section 8.11 Texture Queries: "An INVALID_OPERATION error is generated by GetTextureImage if the effective target is not one of TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_1D_ARRAY, TEXTURE_2D_ARRAY, TEXTURE_CUBE_MAP_ARRAY, TEXTURE_RECTANGLE, or TEXTURE_CUBE_MAP (for GetTextureImage only)." Note that this differs from the original ARB_direct_state_access spec. However, the EXT_direct_state_access version does take a target parameter, so it should continue reporting INVALID_ENUM. Fixes KHR-GL45.direct_state_access.textures_image_query_errors.
