Now 'From' and 'To' arguments must be omitted in functions
and structures related to routing.
The commit deprecates the following functions:
ejabberd_router:route/3 in favor of ejabberd_router:route/1
ejabberd_router:route_error/4 in favor of ejabberd_router:route_error/2
ejabberd_local:route_iq/4 in favor of ejabberd_local:route_iq/2
ejabberd_local:route_iq/5 in favor of ejabberd_local:route_iq/3
The format of {route, From, To, Packet} is changed in favor of {route, Packet}
If set to 'true' (this is the default), new processes spawned by
ejabberd_listener will be attached to the corresponding supervisor.
No such processes will be attached to a supervisor otherwise.
Setting this to 'false' will improve performance of high loaded
systems where new C2S/S2S processes are spawned very rapidly.
Check whether the 'from' and 'to' attributes are valid before bouncing
or resending a stanza from the stream management queue. They might be
invalid in certain corner cases.
Thanks to Evgeniy for spotting this.
Close the connection if a stream management client fails to respond to
an acknowledgement request within 60 seconds. This number of seconds
can be changed with the new "ack_timeout" option, and the mechanism can
be disabled by specifying 'infinity'.
As a side effect of this change, a new acknowledgement is no longer
requested before the response to the previous request is received.
The CSI state is always set to 'active' when a stream management session
is resumed; so there's no need to apply the CSI state of the old c2s
process, first.
If session resumption failed because requesting the #state from the old
c2s process took too long, the new c2s process will usually receive the
response. Let the new process handle that case gracefully.
During stream resumption, the #state is transferred from the old c2s
process to the new one. This is usually very fast, but under certain
conditions, it can take longer than five seconds.
If a message stanza is blocked as per XEP-0016 or XEP-0191 and the
stanza is marked as a private MUC message, don't return an error. This
makes sure users won't be kicked from MUC rooms when blocking other
participants.
