Several documentation callbacks (doc/0 and mod_doc/0) are implemented
and `ejabberdctl man` command is added to generate a man page. Note
that the command requires a2x to be installed (which is a part of
asciidoc package).
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restarts the process with outdated options.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.
Fix mod_http_upload_quota's process name lookup for the case where a
slot is requested by a JID whose domain part is not the virtual host the
mod_http_upload_quota process is running on.
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 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.
The mod_http_upload_quota module attempts to delete a directory whenever
it removes a file from that directory. However, if thumbnail creation
is enabled, directories will often contain two files. Therefore, don't
log an info (but only a debug) message if directory removal fails.
mod_http_upload_quota implements two features:
- When a "hard quota" is exceeded during a file upload, old files are
removed until the disk usage equals or falls below the "soft quota".
- Once a day, all uploaded files (and directories) older than a
configurable number of days are deleted.
