If we add files to the shared directory, the XMPP message signaling this file to the others contains a list of block indexes and their hashes. Apparently files above 1GB cause the new-file message to oversize and abort with
stream:error (text)
I temporarily disabled chunk encryption because it drastically slowed down the data transfer. Some numbers:
Scenario: 3 peers, one has new 100mb file
Distribution with AES128 encryption: ~30secs
Distribution without encryption: ~0.4secs
Investigating this problem.
On first start auto-create unique JID and save to identity-file, or check for existing. On each start ask for password that is used to encrypt/decrypt identity-file.
The XMPP Thread does not receive messages anymore if a remote peer downloads a big file (happened with 50MB file) from you.
An "active only" node is a node that always actively establishes the connections to other nodes. This should be useful in case you cannot open a port in your firewall/router. This is especially the case if some of the peers use DualStack-Lite (IPv6 own address, IPv4 only via gateway) and others have real IPv4 addresses.
Of course this only works if few nodes are "active only".
We still need to implement some handling for broken internet connections or simple IP changes on DSL connections.
