If set up, this hub will be used to subscribe to feeds that don't specify a hub of their own.
Assumes that the fallback hub will, in fact, handle polling and updates for any feed we throw at it!
Authentication may be specified for the fallback hub.
Example:
$config['feedsub']['fallback_hub'] = 'https://superfeedr.com/hubbub';
$config['feedsub']['hub_user'] = 'abcd';
$config['feedsub']['hub_pass'] = 'ckcmdkmckdmkcdk';
Also:
* Fix for WordPress-RSS-via-Superfeedr-Atom; if we have <author> info but no ID from a native ActivityStreams actor, don't freak out in the low-level processing code that checks for identity matches.
* enhanced messages for low-level FeedSub exceptions if they make it to outside display
The code pattern 'new XXXException($e)' to chain exceptions doesn't actually work as intended, as exceptions are actually expecting a string message here.
This caused an implicit string conversion from HTTP_Request2_Exception, which is a PEAR_Exception, which defines an absurdly detailed __toString() method including a giant HTML table with a backtrace if you happen to be on a web request.
Simply passing $e->getMessage() instead clears this up, as we'll get the nice short message like 'Couldn't connect to tcp://blahblah:80'
Parsing hcards for the data we need wasn't hard enough to justify using
hkit. It was dependent on a number of external systems (something to
run tidy), and only could handle XHTML.
We now parse HTML with the PHP dom libraries used elsewhere, and
scrape out our own hcards. Seems to work nicer and faster and most of
all works with Google Buzz profile URLs.
* Subscription::start was sometimes passing users instead of profiles to hooks, which broke OStatus subscription notifications; now normalizing to profiles for processing.
* H-card parsing would trigger a lot of PHP warnings and notices in hKit. Now suppressing warnings and notices for the duration of the call to keep them out of output when display_errors is on.
* H-card parsing would trigger a PHP fatal error if the source page was not well-formed XML and Tidy was not present on the system. Switched normalization to use the PHP DOM module which is always present, as we have no need for Tidy's extra features here.
* Trying to fetch avatars from Google profiles failed and triggered a PHP warning due to the relative URL not being resolved during h-card parsing. Now passing profile page URL into hKit by sneaking a <base> tag in while we normalize the HTML source.
* Profile pages without a "Link" header could trigger PHP notices due to a bad NULL -> array(NULL) conversion in LinkHeader::getLink(). Now checking that there was a return value before converting single return value into array.
- add event hooks to profile update pings
- send Salmon pings with custom update-profile event to OStatus subscribees and groups (subscribers will see it on your next post)
- fix OStatus queues with overlong transport names, should work on DB queues now
- Ostatus_profile::notifyActivity() and ::notifyDeferred() now can take XML, Notice, or Activity for convenience
- added rel="ostatus:attention" links for group delivery
- added events for plugins to override group profile/permalink pages
- pulled Notice::saveGroups up to save-time so we can override;
it's relatively cheap and gives us a clean list of target
groups for distrib time even with customized delivery.
- fixed notice::getGroups to return group objects as expected
- added some doc on new parameters to Notice::saveNew
- 'groups' list of group IDs to push to in place of parsing
- messages that come in via PuSH and contain local group targets
are delivered to local group members
- messages that come in via PuSH and contain remote group targets
are delivered to local members of the remote group
Todo:
- handle group posts that only come through Salmon
- handle conflicts in case something comes in both through Salmon and PuSH
- better source verification
- need a cleaner interface to look up groups by URI
- need a way to handle remote groups with conflicting names
- set minimal error page output on PuSH callback
- allow hub to retry ($config['ostatus']['hub_retries']), simplify internal iface a bit. Retries are pushed to end of queue but otherwise not delayed yet; makes delivery more robust to one-off transitory errors but not yet against downtime.
- actually udpate feedsub.last_update when we get a new PuSH update in
- move incoming PuSH processing to a queue handler to minimize time spent before POST return, as recommended by PuSH spec. When queues are disabled this'll still be handled immediately.
Added support for favoring and disfavoring in OStatusPlugin.
Needed to represent the Notice as an activity:object, so added
some code for that in lib/activity.php.
Also, made some small changes to OStatusPlugin so it handled
having a non-default argument $object correctly.
* HMAC now calculated correctly - confirmed interop with Google's public hub
* Can optionally use an external PuSH hub, set URL in $config['ostatus']['hub']
(may have issues in replication environment, and will ping the hub for every
update rather than just those with subscribers) Internal hub will still function
when this is set, but won't be advertised. Warning: setting this, then turning
it off later will break subscriptions as that hub will no longer receive pings.
* detection of group feeds is currently a nasty hack based on presence of '/groups/' in URL -- should use some property on the feed?
* listing for the remote group is kinda cruddy; needs to be named more cleanly
* still need to establish per-author profiles (easier once we have the updated Atom code in)
* group delivery probably not right yet
* saving of group messages still triggering some weird behavior
Added support for since_id and max_id on group timeline feeds as a free extra. Enjoy!
* Treat linkless feed posts as status updates; drop the "New post:" prefix and quotes on them.
* Use stable user IDs for atom/rss2 feed links instead of unstable nicknames
* Pull Atom feed preferentially when subscribing -- can now put the remote user's profile page straight into the feed subscription form and get to the right place.
* Clean up naming for push endpoints
* renamed FeedSub plugin to OStatus
* now setting avatar on subscriptions
* general fixes for subscription
* integrated PuSH hub to handle only user timelines on canonical ID url; sends updates directly
* set $config['feedsub']['nohub'] = true to test w/ foreign feeds that don't have hubs (won't actually receive updates though)
* a few bits of code documentation
* HMAC support for verified distributions (safest if sub setup is on HTTPS)
And a couple core changes:
* minimizing HTML output for exceptions in API requests to aid in debugging
* fix for rel=self link in apitimelineuser when id given
This does not not yet include any of the individual subscription management (Salmon notifications for sub/unsub, etc) nor a nice UI for user subscriptions.
Needs some further cleanup to treat posts as status updates instead of link references.
