Refuse filtering anon MUC MAM queries by JID even if it's the client's
own JID. Clients probably won't perform such queries in practice, so
the additional complexity is unnecessary.
The changes are very similar to those from previous commit:
* Now there is no need to pass validating function in
gen_mod:get_opt() and gen_mod:get_module_opt() functions,
because the modules' configuration keeps already validated values.
* New functions gen_mod:get_opt/2 and gen_mod:get_module_opt/3 are
introduced.
* Functions gen_mod:get_opt/4 and get_module_opt/5 are deprecated.
If the functions are still called, the "function" argument is
simply ignored.
* Validating callback Mod:listen_opt_type/1 is introduced to validate
listening options at startup.
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}
When multiple resources have the same (highest) priority, ejabberd_sm
dispatches messages addressed to the bare JID (or to an unavailable
resource) to each of these resources. Such messages are now marked with
an 'sm_copy' flag for all but one of the resources. This makes it
easier for other modules to identify those duplicates.
Resolves#1356.
Use the user (or room) JID instead of the server JID for the 'by'
attribute of <stanza-id/> and <archived/> tags. That's what the
examples in XEP-0313 v0.2 and XEP-0359 v0.3.0 suggest.
XEP-0313 says: "a server SHOULD include in a user archive all of the
messages a user sends or receives of type 'normal' or 'chat' that
contain a <body> element."
