blazingmq/src/groups/mqb/mqbc/mqbc_storageutil.cpp

Lines 3005 to 3045 in c377025

	if (isCSLMode) {
	const bsls::Types::Int64 numMsgs = rs->numMessages(
	mqbu::StorageKey::k_NULL_KEY);
	if (0 != numMsgs) {
	BMQTSK_ALARMLOG_ALARM("REPLICATION")
	<< clusterDescription << " Partition [" << partitionId
	<< "]: Attempt to delete storage for queue [ " << uri
	<< "], queueKey [" << queueKey << "] which has ["
	<< numMsgs << "] outstanding messages."
	<< BMQTSK_ALARMLOG_END;
	if (status) {
	*status = rc_QUEUE_HAS_MESSAGES;
	}
	return; // RETURN
	}
	const mqbs::ReplicatedStorage::RecordHandles& recHandles =
	rs->queueOpRecordHandles();
	for (size_t idx = 0; idx < recHandles.size(); ++idx) {
	fs->removeRecordRaw(recHandles[idx]);
	}
	}
	BALL_LOG_INFO << clusterDescription << ": Partition [" << partitionId

	if (status) {
	*status = rc_SUCCESS;
	}
	return; // RETURN
	}
	// A specific appId is being deleted.
	if (isCSLMode) {
	rs->purge(appKey);
	}
