If a listener is started or stopped via ejabberd_listener:add_listener/3
or ejabberd_listener:delete_listener/3, the configuration for all
listener modules is updated using the Module:transform_listen_option/2
function for each listener module that exports such a function.
However, for listener modules that don't provide that function (such as
ejabberd_stun), all but one option was dropped. This is now fixed.
The issue could be triggered e.g. by enabling mod_proxy65 in the modules
section.
An earlier version of XEP-0280 specified the <received/> and <sent/>
tags to be siblings of the <forwarded/> element, whereas the current
version mandates them to be parents of <forwarded/>. The mod_carboncopy
module supports both variants. However, the check that makes sure
clients won't receive a copy of the messages they sent didn't work for
the old-style schema. This is now fixed.
Log one instead of three [info] messages when XEP-0280 (Message Carbons)
support is enabled or disabled successfully. On failure, log an
additional [warning].
On stanza queue overflow, pass a message to self() using the exclamation
mark operator instead of send_all_state_event/2. This allows for
reusing the existing handler for 'kick' events.
On queue overflow, terminate the c2s session instead of just dropping
items from the queue. This makes sure all stanzas are either delivered
or bounced.
When the FSM goes into the 'wait_for_resume' state, let fsm_next_state/2
take care of updating #state.mgmt_state and of writing the log line.
This doesn't change the behavior, but simplifies the code.
The 'previd' value provided by the client during a session resume
request includes the client's JID and ejabberd's session ID. If there
is a session for the requested JID but with a different session ID,
resumption should fail, but that session shouldn't be closed. This
commit makes sure the latter won't happen.
In practice, this will only make a difference in odd corner cases.
If stream management is enabled, don't exit the c2s process when
ejabberd_socket:send/2 fails, but close the socket instead. This gives
the client a chance to resume the session.
Thanks go to Matthias Rieber for reporting the issue, providing detailed
logs, and testing the fix.
