Method tuMapDispatch

SIP/SIP2Interface.cpp:254–263

Attempt to dispatch an incoming SIP message to a TU; return true if a transaction wanted this message. This has to be locked so someone doesnt delete the TU between the time we get its pointer and send it the message.

// This has to be locked so someone doesnt delete the TU between the time we get its pointer
// and send it the message.
bool SipTUMap::tuMapDispatch(SipMessage*msg) {
	ScopedLock lock(mTUMap.qGetLock());
	string key = tuMakeKey(msg);
	SipTransaction *tup = mTUMap.readNoBlock(key);
	LOG(DEBUG) <<LOGVAR(msg) <<LOGVAR(tup);
	if (! tup) { return false; }		// Eventually this will be an error, but not everything is transitioned to use TU yet.
	WATCH("SIP recv: Sending message to TU "<< tup->stGetMethodNameV());
	tup->TLWriteHighSide(msg);
	return true;
}

// Look at all the dead dialogs and delete any that can be deleted safely.
// They can be deleted if their SIP timers have expired and no TranEntry still points to them.
