I noticed that each time a notice was accessed it'd do a remote lookup
with HEAD (and continue despite 404 etc.) and then another attempt to
download the resource. If this wasn't successful new attempts would be
made for each loading of the resource, which is extremely resource
intensive.
Whenever we can say "it's been n seconds since the last attempt" we
could probably enable this again - or just manually reload remote
thumbnails (as part of the StoreRemoteMedia plugin etc.)
The code was so involved there was even a comment asking for a refactor.
Now, File_redirection::where always returns a nice File_redirection
object instead of an array or string or nothing. The object is
either one which already existed or else a new, unsaved object.
Instead of duplicating "does it exist" checks everywhere, do it in
File_redirection::where. You either get what exists or something to save.
An unsaved File_redirection may be paired with an unsaved File.
You will want to save the File first (using ->saveFile()) and put the
id in File_redirection#file_id before saving.
So far we only trust i.ytimg.com for YouTube thumbnails, but you can
configure the Oembed plugin in config.php by setting the plugin's class vars:
addPlugin('Oembed', array('param'=>'value', ...));
Some might think this is a security risk or privacy invasive, but as the Oembed
script is already calling remote sites to get information _about_ linked media,
the way to stop it is to disable the Oembed plugin. However it is not certain
it has been migrated out into a plugin properly yet. But try it if you want 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:

htmLawed cleans stuff out properly, but there's no very good way right
now to show text/html attachments, since everything gets jumbled up with
our own CSS etc. Best would be an iframe or just a new tab or so.
