  "message": "os: fix a race between Process.signal() and wait() on Windows\n\nProcess.handle was accessed without synchronization while wait() and\nsignal() could be called concurrently.\n\nA first solution was to add a Mutex in Process but it was probably too\ninvasive given Process.handle is only used on Windows.\n\nThis version uses atomic operations to read the handle value. There is\nstill a race between isDone() and the value of the handle, but it only\nleads to slightly incorrect error codes. The caller may get a:\n\n  errors.New(\"os: process already finished\")\n\ninstead of:\n\n  syscall.EINVAL\n\nwhich sounds harmless.\n\nFixes #9382\n\nChange-Id: Iefcc687a1166d5961c8f27154647b9b15a0f748a\nReviewed-on: https://go-review.googlesource.com/9904\nReviewed-by: Alex Brainman \u003calex.brainman@gmail.com\u003e\nRun-TryBot: Alex Brainman \u003calex.brainman@gmail.com\u003e\nTryBot-Result: Gobot Gobot \u003cgobot@golang.org\u003e\n",
