  "message": "[dawn][native] Fixes TSAN race from GetCompilationInfo.\n\n- The race happens when multiple threads Complete the\n  CompilationInfoEvent. The call to\n  OwnedCompilationMessages::GetCompilationInfo was writing\n  to the owned copy of CompilationInfo in both threads. Note\n  that in practice, the competing threads would have written\n  the same things.\n- Adds an atomic bool to gate writing to the internal\n  CompilationInfo struct that should only ever be written\n  once.\n- Updates some of the asserts to use the new bool to be\n  explicit.\n\nBug: 373845830\nChange-Id: I3998a276bc210bc5bf5bccfe31c44b4e01de4472\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/211947\nReviewed-by: Shrek Shao \u003cshrekshao@google.com\u003e\nAuto-Submit: Loko Kung \u003clokokung@google.com\u003e\nReviewed-by: Geoff Lang \u003cgeofflang@chromium.org\u003e\nCommit-Queue: Geoff Lang \u003cgeofflang@chromium.org\u003e\n",
