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 option can be used as a replacement of 'host' option
when several (sub)domains are needed to be registered for the module.
Note that you cannot combine both 'host' and 'hosts' in the config
because 'host' option is of a higher priority. Example:
mod_pubsub:
...
hosts:
- "pubsub1.@HOST@"
- "pubsub2.@HOST@"
Fixes#1883
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.
Now that plugins directly use ejabberd_mnesia and can include their own
transform handler, we don't need pubsub_migrate anymore.
People upgrading from 2.1.1x version must upgrade to 17.01 first.
pubsub_migrate module remains to support any manual process requiring it
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}
