gnusocial-jp/plugins/OStatus

Plugin to support importing and exporting notices through Atom and RSS feeds.
The OStatus plugin concentrates on user-to-user cases for federating StatusNet
and similar social networking / microblogging / blogging sites, but includes
low-level feed subscription systems which are used by some other plugins.

Uses WebSub (previously named PubSubHubbub or PuSH) for push feed updates;
currently non-WebSub feeds cannot be subscribed unless an external
WebSub hub proxy is used.


Configuration options available:

$config['ostatus']['hub']
(default internal hub)
Set to URL of an external WebSub hub to use it instead of our internal hub
for sending outgoing updates in user and group feeds.

$config['ostatus']['hub_retries']
(default 0)
Number of times to retry a WebSub send to consumers if using internal hub


Settings controlling incoming feed subscription:

$config['feedsub']['fallback_hub']
To subscribe to feeds that don't have a hub, an external WebSub proxy hub
such as Superfeedr may be used. Any feed without a hub of its own will
be subscribed through the specified hub URL instead. If the external hub
has usage charges, be aware that there is no restriction placed to how
many feeds may be subscribed!

$config['feedsub']['fallback_hub'] = 'https://superfeedr.com/hubbub';

$config['feedsub']['hub_user']
$config['feedsub']['hub_password']
If using the fallback hub mode, these settings may be used to provide
HTTP authentication credentials for contacting the hub. Default hubs
specified from feeds are assumed to not require


For testing, shouldn't be used in production:

$config['ostatus']['skip_signatures']
(default use signatures)
Disable generation and validation of Salmon magicenv signatures

$config['feedsub']['nohub']
(default require hub)
Allow low-level feed subscription setup for feeds without hubs.
Not actually usable at this stage, OStatus will check for hubs too
and we have no polling backend. (The fallback hub option can be used
with a 3rd-party service to provide such polling.)

Todo:
* better support for feeds that aren't natively oriented at social networking
* make use of tags/categories from feeds
* better repeat handling
