`wgpuBufferGetMapState` buggy on Web #27

Open GeraldKimmersdorfer opened 1 month ago

GeraldKimmersdorfer commented 1 month ago

On the web wgpuBufferGetMapState seems to return 0 in any state. 0 is not even a valid option for WGPUBufferMapState.

On native the function returns the appropriate values. Maybe an emscripten bug?

I'll introduce a manual flag in our RawBuffer-Implementation which we can then use instead.

Seems to be an emscripten bug where wgpuBufferGetMapState's return values don't align with WGPUBufferMapState enum values.

See https://github.com/emscripten-core/emscripten/issues/22300

Update: Our PR was merged three weeks ago and is included in the emscripten 3.1.65 (released two weeks ago)

Therefore, this issue will be fixed when we update the emscripten version again.
