Retrying undelivered packets should only happen for payload packets in cluster (#1513)

Wojciech Kapcia (Tigase) opened 2 years ago

In case of writing packet to socket problem, packet may be slated for re-delivery, but this only should apply to proper cluster payload packets (IQ and message stanzas).


Context: there was a problem with connectivity, which resulted in NPE because tigase tried to re-deliver  `<handshake/>` packet, which should have been dropped. What's more, particular point may result in subsequent closing of the connection:

I've added check to ensure only <cluster/> and <route/> packets are redelivered as according to processPacket() method, all other packets are wrapped as one of those. Remaining packets are packets used for handshaked or ping and should be dropped.
