When the user interrupts the shell with Ctrl-C (or similar), the shell will check to see if any operations are in progress, and if so, prompt the user to kill them. However, after getting the currentOp results, the code assumes that there will be an inprog field — but this is not present if the currentOp fails (for example, due to a lack of auth). This causes an assertion to be tripped inside BSONElement::embeddedObject().
void ConnectionRegistry::killOperationsOnAllConnections(bool withPrompt) const { Prompter prompter("do you want to kill the current op(s) on the server?"); stdx::lock_guard<stdx::mutex> lk(_mutex); for (map<string, set<string>>::const_iterator i = _connectionUris.begin(); i != _connectionUris.end(); ++i) { auto status = ConnectionString::parse(i->first); if (!status.isOK()) { continue; } const ConnectionString cs(status.getValue()); string errmsg; std::unique_ptr<DBClientWithCommands> conn(cs.connect(errmsg)); if (!conn) { continue; } const set<string>& uris = i->second; BSONObj currentOpRes; conn->runPseudoCommand("admin", "currentOp", "$cmd.sys.inprog", {}, currentOpRes); auto inprog = currentOpRes["inprog"].embeddedObject(); BSONForEach(op, inprog) { if (uris.count(op["client"].String())) { if (!withPrompt || prompter.confirm()) { BSONObjBuilder cmdBob; BSONObj info; cmdBob.append("op", op["opid"]); auto cmdArgs = cmdBob.done(); conn->runPseudoCommand("admin", "killOp", "$cmd.sys.killop", cmdArgs, info); } else { return; } } } } }
Repro:
- Start auth mongod
- Run a slightly slow non-privileged command
- Immediately hit Ctrl-C
