[Piglit] [PATCH 11/14] arb_direct_state_access: Add a test for glGetVertexArray*iv

Laura Ekstrand laura at jlekstrand.net
Fri Apr 3 10:38:53 PDT 2015


I just filed the bug.  I discovered something interesting in the process:

The spec for GetVertexAttrib*v explains how to query
VERTEX_ATTRIB_ARRAY_BUFFER_BINDING
and VERTEX_ATTRIB_BINDING, but these functions are non-DSA.
The spec for GetVertexAttrib*v also has a very helpful line,

    "Queries of VERTEX_ATTRIB_ARRAY_BUFFER_BINDING and
    VERTEX_ATTRIB_ARRAY_DIVISOR map the requested attribute index
    to a binding
    index via the VERTEX_ATTRIB_BINDING state, and then return the
    value of
    VERTEX_BINDING_BUFFER or VERTEX_BINDING_DIVISOR, respectively."
