This error condition is defined within stream errors, however,
XEP-0198 says:
> This element SHOULD contain an error condition, which MUST
> be one of the **stanza** error conditions defined in RFC 6120.
The header consisted of too many unrelated stuff and macros misuse.
Some stuff is moved into scram.hrl and type_compat.hrl.
All macros have been replaced with the corresponding function calls.
TODO: probably type_compat.hrl is not even needed anymore since
we support only Erlang >= OTP 17.5
Some mobile apps might only be notified on actual chat messages with
a body, so don't let mod_push_keepalive reset the stream management
timeout on other types of traffic.
During resumption, make sure the old process and the corresponding
session entry are disposed also in the case where the call that queries
the old process times out.
If the client acknowledged more stanzas than the server sent, close the
connection with a stream error rather than hiding client bugs by silently
adjusting the server's count.
The callback is supposed to provide known options and their default
values, as long as the documentation. Passing default values into
get_mod functions is now deprecated: all defaults should be provided
by the Mod:mod_options/1 callback.
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.
Users with large rosters and/or certain transports might receive a very
large number of (e.g.) presence and/or PEP stanzas after logging in.
Clients might take some time to acknowledge them, especially over slow
(mobile) connections.
This module tries to keep pending stream management sessions of push
clients alive (as long as the disconnected clients are reachable via
push notifications).
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.
If a pending stream management session times out, call
ejabberd_c2s:process_terminated/2 *before* storing the incoming stanza
count. Without this change, the session table entry that holds the
stanza count was purged while closing the session.
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.
