The by-name read was a stub, so it left the caller's buffer untouched and a test comparing it against a reference saw whatever that memory already held. Its by-target sibling glGetBufferSubData was already implemented, so this is that function with the buffer resolved by name instead of through a binding: the same non-negative offset and size check, the same bound-by-the-buffer's-size check, the same refusal to read a buffer mapped without GL_MAP_PERSISTENT_BIT, and the same SyncGpuWrites before the download so a GPU-side write that has not landed yet is not missed. Resolving by name reports INVALID_OPERATION for a name that is not a buffer, which the by-target form expresses as "target is bound to no buffer object" instead. direct_state_access.buffers_get_named_buffer_subdata passes on both backends.
