This bug was hitting a number of places where we had the pattern:
$db->find();
while($dbo->fetch()) {
$x = clone($dbo);
// do anything with $x other than storing it in an array
}
The cloned object's destructor would trigger on the second run through the loop, freeing the database result set -- not really what we wanted.
(Loops that stored the clones into an array were fine, since the clones stay in scope in the array longer than the original does.)
Detaching the database result from the clone lets us work with its data without interfering with the rest of the query.
In the unlikely even that somebody is making clones in the middle of a query, then trying to continue the query with the clone instead of the original object, well they're gonna be broken now.
* 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.
Base problem is that our caching-on-insert interferes with relying on column default values; the cached object is missing those fields, so they appear to be empty (null) when the object is retrieved from cache.
Now explicitly setting them when inserting subscriptions, and cleaned up some code that had alternate code paths.
May also have made auto-subscription work for remote OStatus subscribers, but can't test until magic sigs are working again.
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.
On my test system (without memcache), while testing the LDAP
authentication plugin, when I sign in for the first time, triggering
auto-registration, I get these messages in the output page:
Warning: ksort() expects parameter 1 to be array, null given in /home/jeff/Documents/code/statusnet/classes/Memcached_DataObject.php on line 219
Warning: Invalid argument supplied for foreach() in /home/jeff/Documents/code/statusnet/classes/Memcached_DataObject.php on line 224
Warning: assert() [function.assert]: Assertion failed in /home/jeff/Documents/code/statusnet/classes/Memcached_DataObject.php on line 241
(plus two "Cannot modify header information..." messages as a result of
the above warnings)
This change appears to fix this (although I can't really explain exactly
why).
Also stripping id from foreign HTML messages (could interfere with UI) and disabled failing attachment popup for a.attachment links that don't have a proper id, so you can click through instead of getting an error.
Issues:
* any other links aren't marked and saved
* inconsistent behavior between local and remote attachments (local displays in lightbox, remote doesn't)
* if the enclosure'd object isn't referenced in the content, you won't be offered a link to it in our UI
We only need one author for user feeds: the user themselves. So, show
the user as the activity:subject, and don't repeat the same
activity:actor for every notice unnecessarily.
In a federated system, "@nickname" is insufficient to uniquely
identify a user. However, it's a very convenient idiom. We need to
guess from context who 'nickname' refers to.
Previously, we were using the sender's profile (or what we knew about
them) as the only context. So, we assumed that they'd be mentioning to
someone they followed, or someone who followed them, or someone on
their own server.
Now, we include the notice information for context. We check to see if
the notice is a reply to another notice, and if the author of the
original notice has the nickname 'nickname', then the mention is
probably for them. Alternately, if the original notice mentions someone
with nickname 'nickname', then this notice is probably referring to
_them_.
Doing this kind of context sleuthing means we have to render the
content very late in the notice-saving process.
