We want to both (a) take a lock on the UserProfile row, and (b)
modify the passed-in UserProfile object, so that callers see the
changes in the object they hold. Unfortunately,
`select_for_update` cannot be combined with `refresh_from_db`
(https://code.djangoproject.com/ticket/28344). Call
`select_for_update` and throw away the result, so that we know we have
the lock on the row, then re-fill the `user_profile` object with the
values now that the lock exists.
Limiting only by client_name and query leads to a very poorly-indexed
lookup on `query` which throws out nearly all of its rows:
```
Nested Loop (cost=50885.64..60522.96 rows=821 width=8)
-> Index Scan using zerver_client_name_key on zerver_client (cost=0.28..2.49 rows=1 width=4)
Index Cond: ((name)::text = 'zephyr_mirror'::text)
-> Bitmap Heap Scan on zerver_useractivity (cost=50885.37..60429.95 rows=9052 width=12)
Recheck Cond: ((client_id = zerver_client.id) AND ((query)::text = ANY ('{get_events,/api/v1/events}'::text[])))
-> BitmapAnd (cost=50885.37..50885.37 rows=9052 width=0)
-> Bitmap Index Scan on zerver_useractivity_2bfe9d72 (cost=0.00..16631.82 rows=..large.. width=0)
Index Cond: (client_id = zerver_client.id)
-> Bitmap Index Scan on zerver_useractivity_1b1cc7f0 (cost=0.00..34103.95 rows=..large.. width=0)
Index Cond: ((query)::text = ANY ('{get_events,/api/v1/events}'::text[]))
```
A partial index on the client and query list is extremely effective
here in reducing PostgreSQL's workload; however, we cannot easily
write it as a migration, since it depends on the value of the ID of
the `zephyr_mirror` client.
Since this is only relevant for Zulip Cloud, we manually create the
index:
```sql
CREATE INDEX CONCURRENTLY zerver_useractivity_zehpyr_liveness
ON zerver_useractivity(last_visit)
WHERE client_id = 1005
AND query IN ('get_events', '/api/v1/events');
```
We rewrite the query to do the time limit, distinct, and count in SQL,
instead of Python, and make use of this index. This turns a 20-second
query into two 10ms queries.
We’re currently generating the icon font in five formats: Embedded
OpenType, WOFF, WOFF2, TrueType, and SVG. But they’re misordered by
webfonts-loader such that modern browsers always select the WOFF
version. WOFF2 is supported by all modern browsers, so just use that
exclusively.

This does two important things:
1. Fix return type of get_identity_dict_from_session to correctly be
Optional[Union[RemoteBillingIdentityDict, LegacyServerIdentityDict]].
RemoteBillingIdentityDict is the type in the 8.0+ auth flow,
LegacyServerIdentityDict is the type in old servers flow, where only
the server uuid info is available.
2. The uuid key used in request.session["remote_billing_identities"]
should be explicitly namespaced depending on which flow and type
we're
dealing with - to avoid confusion in case of collisions between a
realm and server that have the same UUID. Such a situation should not
occur naturally and I haven't come up with any actual exploitation
ideas that could utilize this by manipulating your server/realm
uuids, but it's much easier to just not think about such collision
security implications by making them impossible.
Previously, dragging an image and dropping it in on itself led to the
image being re-uploaded, which is probably not the intent of a user.
This commit prevents this reuploading of the same image by explicitly
checking if the image is being dragged onto itself, and then rejecting
this action.
We reduced the width of "Actions" column too much in stream subscribers
and group members list when there were no users matching the text in
search input and it did not look good because of "Actions" heading
being shifted to extreme right.
This commit fixes it by removing the "actions" class on the heading,
which was used to set the width to "1%" which is needed for tables
with only icons in buttons to avoid unused space but not here.
As a result of removing this class, the CSS of "min-width: 100px"
is being applied to the column, but that's fine atleast for stream
subscribers list as it did not look good before due to scrollbar
overlapping the buttons and it looks better now.
For the group members list, we set min-width to 80px, as we do
not require 100px width and it is enough to avoid overlapping
scrollbars to an extent.
The overlapping scrollbars problem is still not fixed completely
but that will handled in a separate commit. This commit was
just to make the heading row look better when there are no users
in the list.
