描述

Description When running a wasm binary on Firefox Nightly with tracing enabled (as per this, the generated trace.ron file is missing a final ]. As a result, the player fails with an "unexpected EOF" error. Manually adding the ] allows the player to work.

Compared to tracing the same program compiled natively, it's also missing various DestroyBindGroup/DestroyBuffer etc. calls, which might be related to the final ] being missing.

Platform MacOS 11.4, wgpu latest (e27fbb821bb3397069d0a82ef8da8e151feb0647), Firefox Nightly 2021-07-07.

研究方向
Investigate the trace file generation code in wgpu to ensure the closing bracket is written. Compare the native trace generation with the wasm path. Look at the Player's RON parsing. Possibly related to missing Destroy calls; check if they are being emitted and not flushed before EOF.
