When modules for some virtual host are about to be started,
they are topologically sorted to preserve dependencies order.
We now keep this order for stop/reload functions to work properly.
The option can be used to override configuration options of a
particular PubSub node. Example:
mod_pubsub:
...
force_node_config:
"eu.siacs.conversations.axolotl.*":
access_model: whitelist
"*":
persist_items: true
Fixes#2276
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.
The options "inet", "inet6" and "backlog" are valid listen options, but are
currently logged as errors (even though they do work):
2018-02-28 16:08:44.141 [error] <0.338.0>@ejabberd_listener:validate_module_option:630 unknown listen option 'backlog' for 'ejabberd_c2s' will be likely ignored, available options are: access, shaper, certfile, ciphers, dhfile, cafile, client_cafile, protocol_options, tls, tls_compression, starttls, starttls_required, tls_verify, zlib, max_fsm_queue
This adds the necessary validators so they are correctly recognized.
Call Mod:handle_auth_success/4 and Mod:handle_auth_failure/4 before
sending the SASL response rather than afterwards. This way, callbacks
can send a custom response and disconnect.
Incoming MUC PMs aren't carbon-copied, as the MUC service usually forks
them. However, don't suppress copying of outgoing PMs, where no such
forking takes place.
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.
The option is supposed to be used when `allow_local_users`
and `allow_transports` are not enough. It's an ACL where `deny`
means the message will be rejected (or a CAPTCHA would be
generated for a presence), and `allow` means the sender is
whitelisted and the stanza will pass through.
The default value is `none`, which means nothing is whitelisted.
The option emulates legacy behaviour which registers all routes
defined in `hosts` on a component connected. This behaviour
is considered harmful in the case when it's desired to multiplex
different components on the same port, so, to disable it,
set `global_routes` to `false`. The default value is `true`,
e.g. legacy behaviour is emulated: the only reason for this is
to maintain backward compatibility with existing deployments.
Since we got rid of all bottle-neck processes and we have
a connection pool for every database, the option is no longer
needed and in fact is detrimental: in practice what you get
is just a bunch of overloaded processes in the IQ handlers pool
no matter how much you increase the `iqdisc` value.
Given that there are close to zero operators understanding
the meaning of the option and, hence, not using it all,
it's not simply deprecated but completely removed.
The commit also deprecates the following functions:
- gen_iq_handler:add_iq_handler/6
- gen_iq_handler:handle/5
- gen_iq_handler:iqdisc/1
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.
If set to `true`, all incoming XML packets are fully validated
against known schemas. If an error occurs, the packet will be bounced
with the corresponding error reason. The default value is `false`.
The option might be useful to protect client software from sofisticated
bugs related to XML validation as well as for client developers
who want to catch validation errors at early stage of development.
Note that the option might have slight performance impact, so use it
with care on loaded machines.
The option controls how many avatars a user can upload per minute.
The option takes positive integer values. The default is 10.
Note that the option only takes effect when an avatar is about
to convert to a different format, i.e. it implies that `convert`
option is configured.
When the option is set to `true`, the module will generate
CAPTCHA challenges for incoming subscription requests. The option
also implies that option `drop` is set to `true`. Note that
the module won't generate CAPTCHA challenges for messages: they
will still be rejected if `drop` is set to `true`.
Fixes#2246
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.
Even if no suitable C graphics libraries are detected
at compile time, the package is still usable because it
provides `eimp:get_type/1` which is used by mod_avatar.
The option allows to set arbitrary text for disco#info identity name.
Previously, option 'name' was supported by mod_proxy65 and mod_http_upload
only. Now, all the following modules support this option as well:
- mod_disco
- mod_irc
- mod_muc
- mod_multicast
- mod_pubsub
- mod_vcard
Example:
```
modules:
...
mod_disco:
name: "Cool XMPP Server"
...
```
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.
Previous version was inefficient: it had a lot of false positives
along with a lot of false negatives, making its usage pointless.
The new verion is based on memsup(3erl) application: the OOM watchdog is
only started when total OS memory consumption is more than 80%.
A watchdog periodically inspects all running processes and collects
statistics about overloaded ones (those queueing a lot of messages).
If the OOM killer is enabled (`oom_killer: true`), all overloaded
processes would be killed. By default, OOM killer is enabled.
When memory consumption is back to normal, the OOM watchdog is stopped.
