We were using `.order_by('user_profile_id', '-timestamp') in our
UserPresence query in get_status_dicts_for_query.
We don't need a full sort to produce the dictionary of statuses.
In fact the whole operation in Python is still O(N):
- divvy rows up to be per-user in an O(N) pass
- find max row for the 'aggregated' entry in an O(n) pass
per user
The one minor annoyance of this fix is that datetime_to_timestamp
is lossy, so if you naively call to_presence_dict before finding
the "max" row, you get test flakes if rows are created during the
same second. I decided to avoid calling to_presence_dict so there
are fewer moving parts, but there's still the ugly step of having
to remove the "dt" field from the final results.
The commit() call in fix() breaks migrations and tests (unless you
mock) due to outer transactions.
We now explicitly call commit() from the management command.
Usually a small minority of users are eligible to receive missed
message emails or mobile notifications.
We now filter users first before hitting UserPresence to find idle
users. We also simply check for the existence of recent activity
rather than borrowing the more complicated data structures that we
use for the buddy list.
This commit completely switches us over to using a
dedicated model called MutedTopic to track which topics
a user has muted.
This includes the necessary migrations to create the
table and populate it from legacy data in UserProfile.
A subsequent commit will actually remove the old field
in UserProfile.
Instead of peeking directly at the DB to verify our mutes are
set correctly, we now use the library function. This prepares
us to modify the DB internals while preserving the tests.
The double forward slash (//) after the protocol in URLs was being
mistakenly considered the beginning of an inline JS comment, causing
internationalization strings being cut unexpectedly.
Now the check for inline JS comments is only run in .js files.
Use this new variable to determine if the user already exists while
doing registration. While doing login through GitHub if we press
*Go back to login*, we pass email using email variable. As a result,
the login page starts showing the "User already exists error" if we
don't change the variable.
Admins need to know about private streams to delete them, even
if they are not subscribed. We send the minimal info possible
to the client to allow them to have a UI for that.
The refactor in b46af40bd3 didn't
correctly translate the code for managing request.user and
request._email, resulting in requests for the push notification
bouncer being rejected with this exception:
AttributeError: 'AnonymousUser' object has no attribute 'rate_limits'
