This broke when changing the database to utf8mb4 instead of utf8,
since utf8_general_ci wasn't accepted and the engine fell back to
utf8mb4_bin. Now we're back in case insensitive search business!
For example the public timeline would show notices from a user with
private_stream configured. (previously it would only hide _new_ notices
by this user as they would be the only ones with notice scoping set).
This means we import the URI string from remote instances to track their
conversations and are able to stitch together replies in a single thread.
We might have to try to avoid collisions so noone remotely can predict
conversation URIs which we generate on our server, causing a DoS kind of
problem.
If we know the URI sent from the remote party, and we don't know the
notice it is replying to, we might still be able to put it in the same
conversation thread!
Getting rid of NoticeListItemAdapter, putting more into ActivityHandlerPlugin
and relying on plugins to handle rendering code of the content. This gives us
a lot more structure and consistency in notice structure and allows activity
plugins to stop rendering certain kinds of notices more easily.
There should also be a property for an ActivityHandlerPlugin class to avoid
rendering notices in the ordinary stream, so we don't have to overload stuff.
saveActivity will accept an Activity which gets parsed and saved through
plugins. So when an ActivityHandlerPlugin (such as Favorite will be soon)
gets a feed to save, this will be the function called instead of saveNew.
The code is now more event-driven when it comes to rendering notices
and their related HTML elements, since we can't have direct calls from
core to a plugin.
lib/activitymover.php has a function to move a Favorite activity which
will not happen now. The move must be pluginified and performed as an
event which plugins can catch on to.
No validation has been attempted yet. Lots of changes left. This
is visibly not (very) different from the previous CSS layout. But
some simplifications have been made.
Might cause issues with local changes to themes and CSS. Also maybe
javascript which depends on certain legacy microformats elements.
The move to microformats2 is motivated by the announcement that all
microformats should be migrated to version 2, as of 2014-06-20 at:
