When module's options were updated (e.g. by reloading ejabberd.yml)
and, later, the module's process crashed, gen_mod supervisor
restarts the process with outdated options. This is now fixed.
The mapping between vCard's XML elements and YAML elements
of 'vcard' option is straightforward. For example, if you
want mod_muc to return the following vCard:
```
<vCard xmlns='vcard-temp'>
<FN>Conferences</FN>
<ADR>
<WORK/>
<STREET>Elm Street</STREET>
</ADR>
</vCard>
```
you need to set the configuration as:
```
modules:
...
mod_muc:
vcard:
fn: Conferences
adr:
-
work: true
street: Elm Street
...
```
Now every such string MUST be encapsulated into ?T() macro.
The macro itself is defined in include/translate.hrl.
Example:
-module(foo).
-export([bar/1]).
-include("translate.hrl").
bar(Lang) ->
translate:translate(Lang, ?T("baz")).
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 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
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.
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"
...
```
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 '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}
