Instances of `RegexError` are just asserted as `assert_not_reached` as
they cannot really fail except for allocation failure if the given regex
is valid.
XEP-0260 states that the candidate selected (offered) by the initiator
wins, not the one that was chosen by the initiator (i.e. offered by the
responder).
The Jingle file transfer (XEP-0234) specifies that the receiver of the
file transfer is the one to terminate the session. Otherwise, there
might be a race condition between the XMPP stream and out-of-band SOCKS5
connections.
This means that we no longer rely on the remote end to close the
connection after sending the file, but additionally use the `<size>`
element from the initial file transfer `<description>` to check whether
the file transfer has been completed.
This was motivated by Conversations not closing the connection for
SOCKS5 file transfers.
This is still disabled by default until prioritization is implemented;
otherwise this could be preferred to HTTP uploads.
File sending only works via Jingle In-Band-Bytestreams right now, more
transports are going to be implemented.
To test this, uncomment the line with `JingleFileTransfer` in
libdino/src/application.vala.
For members-only, non-anonymous groups that do not have a name set we now
show an automatically generated name that is generated from the list of members
(offline, and online). Only the first name (before the first space) is used
to keep the generated name short.
The term *private room* is coined as a short hand for members only&non-anon group
chats.
This commit also uses the offline members list instead of the online member list
to generate avatar tiles (also only in members-only, non-anon groups.)
* Implement XEP-0380 in a naive fashion for both the OMEMO and OpenPGP plugins
* Move the XEP-0380 namespace to a constant
* Move the implementation for xep-0380 to its own module
* Remove un-needed lines from plugins/openpgp/src/stream_module.vala
