This fixes a bug where update_message_backend would do one memcached
query per user receiving a given message. Right now we just do a
single bulk database query, but in principle we could use
generic_bulk_cached_fetch to use the cache as well.
One of my commits from yesterday erroneously set the
"mentioned" flag on messages that weren't mentioning
the current user, so you would get the pink/salmon
background when you sent at-mentions to other people.
Now we check the user_id before setting the flag.
Previously, if one starred very old messages (or ones in a stream
you're not subscribed to), your other open browsers would likely throw
an exception syncing the message flag.
It's probably a bug that this throws exceptions sometimes, but it's
not consistently reproducible (or maybe, browser dependent?), and it
isn't really a problem to fail to abort some requests as part of the
page reload process; the abort was just there to make sure as little
as possible is happening so we can garbage-collect effectively.
Apparently, we were comparing the full list of enabled authentication
methods (whether or not supported by the server) against the user's
selections among those supported by the server, which resulted in
authentication methods being always reported as different.
In order to make the layout of all bots consistent, this commit
moves each bot into a folder with its name and modifies 'run.py'
so that only bots with such a structure can be executed. 'lib'
gets renamed to 'bots'.
It turns out we were using malformed URLs in the image tags
(containing just a hostname, but no http(s)!) in what we were passing
to the Django templates for our digest/, which resulted in the Django
templates treating these URLs as http. Gmail recently cracked down on
loading images in HTTP, causing the emoji links to appear broken in
emails Zulip sends.
Fixes#3258.
