Bug 1541216 - Update PR_SetCurrentThreadName() to use prctl(PR_SET_NAME) on Android
47 bytes, text/x-phabricator-request
Details | Review

On android *(void**)(&dynamic_pthread_setname_np) = dlsym(RTLD_DEFAULT, "pthread_setname_np"); fails so the thread name is never set. Investigating, I found that WebRTC uses prctl(PR_SET_NAME, name); and SpiderMonkey just calls pthread_setname_np(pthread_self(), name); directly.
