I've extended the rights framework (centering on the Right class and Profile::hasRight()) to cover
Web login and API use. This will make it possible to prevent login and API use by users.
I added two new Right constants to the Right class: WEBLOGIN and API. I check these rights using
Profile::hasRight() when initializing users. If the rights check fails, I throw an exception.
I created a new AuthorizationException class for this particular
exception, in order to allow a different UI for these kinds of exceptions (or whatever).
Workaround for deleted profiles still appearing in cached subscriptions/subscribers lists: if we couldn't fetch them, don't include them in the ArrayWrapper.
ArrayWrapper doesn't deal well with null entries, which aren't meant to happen in how it works. This code has recently changed from dying directly with a PHP fatal error in that case to throwing an exception, which allows tracking down the caller.
It looks like there might be some cases where profiles and their matching subscriptions get deleted, but the subscription entries don't get properly cleared from cache... that still bears further investigation. The regular code path looks ok; calls Subscription::cancel() from code called in Profile::delete(); but if they're batch-deleted instead of one row at a time, that could fail to trigger.
* adds Right::CREATEGROUP
* logic in Profile::hasRight() checks for silencing
* NewgroupAction checks for the permission before letting you see or process the form in the UI
* User_group::register() logic does a low-level check on the specified initial group admin, and rejects creation if that user doesn't have the right; guaranteeing that API methods etc will also have this restriction applied sensibly.
Made two new functions, Subscription::bySubscriber() and
Subscription::bySubscribed(), to get streams of Subscription objects.
Converted Profile::getSubscribers() and Profile::getSubscriptions() to
use these functions.
Code was doing a batch call to $avatar->delete() which fails to properly engage the file deletion code. Calling the existing profile->delete_avatars() function deletes them individually, which makes it all work nice again.
SubMirror: redid add-mirror frontend to accept a feed URL, then pass that on to OStatus, instead of pulling from your subscriptions.
Profile: tweaked subscriberCount() so it doesn't subtract 1 for foreign profiles who aren't subscribed to themselves; instead excludes the self-subscription in the count query.
Memcached_DataObject: tweak to avoid extra error spew in the DB error raising
Work in progress: tweaking feedsub garbage collection so we can count other uses
to (profile_id, id) instead of (profile_id, created, id).
It's been falling back to PRIMARY instead, which is really
very inefficient for a profile that hasn't posted in a few
months. Even though forcing the index will cause a filesort,
it's usually going to be better. Even for large profiles it
seems much faster than the badly-indexed query.
While deletion is in progress, the account is locked with the 'deleted' role, which disables all actions with rights control.
Todo:
* Pretty up the notice on the profile page about the pending delete. Show status?
* Possibly more thorough account disabling, such as disallowing all use for login and access.
* Improve error recovery; worst case is that an account gets left locked in 'deleted' state but the queue jobs have gotten dropped out. This would leave the username in use and any undeleted notices in place.
It's not currently used, and won't be efficient when we update the notice.profile_id_idx index to optimize for our id-based sorting when pulling user post lists for profile pages, feeds etc.
The subs_* functions in subs.php have made a lot of assumptions
about users versus profiles. I've refactored the functions to
be methods of the Subscription class instead, and to use Profile
objects throughout.
Some of the checks for blocks or existing subscriptions depended
on users or profiles, so I've moved those methods around a bit.
I've left stubs for the subs_* functions until we get time to replace
them.
