Details
Description
The global CommitJob object is destructed on ::exit() before thread execution is halted. This affects the v2.0 branch; master works around this by using a static reference.
To reproduce, send SIGQUIT to the mongod process while flooding a single connection with fire-and-forget writes:
> for (i=0;i<100000;i++) { db.test.insert({ a:1 }); }
|
The resulting crash varies. In the one below, the initAndListen thread receives the SIGQUIT. This thread then ::exit()s, starts destructing the mongo::dur::CommitJob static, generates a SIGSEGV when destructing a vector of Writes (from a TaskQueue<Writes>), then receives it's own SIGSEGV. The durability thread then fails an assertion on pthread_mutex_lock() while in mongo::dur::CommitJob::notifyCommitted()/NotifyAll(). Finally, an execCommand thread calls terminate() due to 'pure virtual method called', invokes myterminate, and gets a SIGABRT. At this point some threads continue to run and the process stops handling signals.
