Now room owners are able to set a preferred language
for the discussions in the room, so other users can
discover rooms based on the language they wish to talk.
TODO: the language format should conform to RFC 5646.
This check should be implemented in 'xmpp' library.
Fixes#2436
Due to historical reasons, ejabberd loads the whole file/data
into the memory when serving an HTTP request. This is now improved:
1) For GET requests ejabberd uses sendfile(2) if the underlying
connection is HTTP and falls back to read/write loop with 64kb
buffer for HTTPS connections. This type of requests are handled
by mod_http_fileserver, mod_http_upload, ejabberd_captcha, etc
2) POST requests are now limited to 20Mb and are fully downloaded
into the memory for further processing (by ejabberd_web_admin,
mod_bosh, etc)
3) PUT requests (e.g. for mod_http_upload) are handled by read/write
loop with 64kb buffer
Now 'muc#roominfo_contactjid' and 'muc#roominfo_pubsub' fields
are returned within muc#roominfo form. Also, both 'muc#roominfo_pubsub'
and 'muc#roomconfig_pubsub' are now validated.
1. Add a request handler in ejabberd_http and explain how to configure the http listener so that the challenges can be solved.
2. Make acme configuration optional by providing defaults in ejabberd_acme.
3. Save the CA that the account has been created in so that it creates a new account when connecting to a new CA.
4. Small spec change in acme configuration.
This is done so that possible future updates to the data structure don't break existing code.
With this change it will be possible to update the data structure and keep the same old persistent data file, which will still have the expected list format but with more properties
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.
