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
Since now, ejabberd doesn't ignore unknown options and doesn't
allow to have options with malformed values. The rationale for
this is to avoid unexpected behaviour during runtime, i.e. to
conform to "fail early" approach. Note that it's safe to reload
a configuration with potentialy invalid and/or unknown options:
this will not halt ejabberd, but will only prevent the configuration
from loading.
***NOTE FOR PACKAGE BUILDERS***
This new behaviour should be documented in the upgrade notes.
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.
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.
The purpose of the module is to cope with legacy and modern
XMPP clients posting avatars. It automatically converts vCard based
avatars (XEP-0153) to PEP based avatars (XEP-0084) and vice versa.
Also, the module supports convertation between avatar image formats on
the fly: this is controlled by `convert` option. For example, to
convert all avatars into PNG format, configure the module as:
mod_avatar:
convert:
default: png
In order to convert only `webp` format to `jpeg`, set the following:
mod_avatar:
convert:
webp: jpeg
Note: the module depends on mod_vcard, mod_vcard_xupdate and mod_pubsub.
Also, ejabberd should be built with --enable-graphics option.
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.
