The option can be used to specify a period (in seconds) for a stream
negotiation to complete. If the timer fires, the stream is considered
as failed and the underlying connection gets closed. This is a global
option (you cannot set it per domain) and the default is 30 seconds.
ejabberd receivers were meant to serve connections from frontends
to backends. However, this approach was not popular and frontend
related code was removed in previous releases. Now, ejabberd receiver's
code was also removed, making the code shorter and cleaner. Also, in
stress tests ejabberd now handles load more robustly, without
c2s processes overload (even with disabled shapers).
ejabberd_socket.erl is renamed to xmpp_socket.erl: it's supposed to
be finally moved into stand-alone xmpp library.
The commit introduces the following changes:
* Now there is no need to pass validating function in
ejabberd_config:get_option() functions, because the configuration
keeps already validated values.
* New function ejabberd_config:get_option/1 is introduced
* Function ejabberd_config:get_option/3 is deprecated. If the function
is still called, the second argument (validating function) is simply
ignored.
* The second argument for ejabberd_config:get_option/2 is now
a default value, not a validating function.
It's now possible to use files as internal packet queues.
The following options are introduced:
* queue_type: the option can be set to `ram` (default) or `file`.
The option can be set per virtual host.
* queue_dir: path to the directory where queues will be allocated.
The default is 'queue' directory inside Mnesia directory.
This is a global option and cannot be set per virtual host.
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.
