We move some of the data setup to the top of the file.
We also remove some get_sub() calls that aren't really
necessary now that peer_data and stream_data are more
independent.
The maybe_clear_subscribers() function was an artifact of
when we used to attach subscribers to the "sub" records in
stream_data.js. I think it was basically a refactoring
shim, and due to some other recent cleanup, it was only
used in test code.
We also change how we validate stream ids.
Going forward, peer_data just looks up stream_ids with the
normal stream_data API when it's trying to warn about
rogue stream_ids coming in. As I alluded to in an earlier
commit, some of the warning code here might be overly
defensive, but at least it's pretty self-contained.
In my recent commit to introduce get_user_set() I
inadvertently skipped one place to call it.
I also remove a return statement that was made
unnecessary by the new get_user_set() helper.
Now when we want to measure how long a block
of code takes to execute, we just wrap it with
`blueslip.measure_time`, instead of the awkward
idiom from my original commit of getting a callback
function.
My rationale for the original scheme was that I
wanted to minimize diffs and avoid changing
`const` to `let` in a few cases, but I believe
now that the function wrapper is nicer.
In a few cases I just removed the blueslip timing
code, since I was able to confirm on czo that
the times were pretty minimal.
We now use the same code in all places to
get the bucket of user_ids that correspond
to a stream, and we consistently treat
a stream as having zero subscribers, not
an undefined number of subscribers, in
the hypothetical case of us asking about
a stream that we're not tracking.
The behavior for untracked streams has
always been problematic, since if a
stream is untracked, all bets are off.
So now if we don't "track" the stream,
the subscriber count is zero. None of
our callers distinguish between undefined
and zero.
And we just consider the stream to be subscribed
by a user when add_subscriber is called,
even if we haven't been told by stream_data
to track the stream. (We also stop
returning true/false from add_subscriber,
since only test code was looking at it.)
We protect against the most likely source
of internal-to-the-frontend bugs by adding
the assert_number() call.
We generally have to assume that the server
is sending us sensible data at page load
time, or all bets are off.
And we have good protections in place
for unknown ids in our dispatch code
for peer_add/peer_remove events.
For the rare case where you're doing a link to a private
stream from a larger private stream that is a superset of
the former, we have bypassed warnings that you are linking
to a private stream.
I'm not sure we need this exemption for any situation
(just let the user bypass the warning), but we definitely
don't want false positives for the exemption.
For now I am closing down this loophole specifically for
Zephyr users.
Zephyr users are special in that we might not get
subscriber info on certain streams.
The current behavior for this edge case is a little
unclear. The current implementation of
peer_data.is_subscriber_subset returns false if both
streams are untracked, but most streams are tracked if we
have a sub for them and just get treated as having an
empty set of subscribers. And an empty set is a subset of
itself. Upcoming changes to our server data are gonna
make this edge case even more annoying to maintain.
We also streamline some of the error handling code
by doing everything up front. This will prevent
scenarios where a single bad stream_id/user_id causes a
bunch of the same warnings in an inner loop.
This removes a bit of complexity. If a piece of
settings code needs to render a stream with
subscribers, it just asks for it.
We no longer have the brittle, action-at-a-distance
mechanism of mutating the subscriber count on to
the stream_data version of a sub.
Stream subs are pretty small, so making copies of
them is cheap, and the blueslip timings from the
previous commit can help confirm that.
There is some discussion of putting `subscriber_count`
on the Stream model, which may eventually get us
away from tracking it in `peer_data.js`, but we will
cross that bridge when we get there. See
https://github.com/zulip/zulip/issues/17101 for
more details.
The weekly stream traffic is a better tiebreaker
for stream typeaheads than subscriber count, as
it's more directly a measure of a stream's current
relevance.
Normally stream traffic and subscriber counts are
closely correlated, but a good example for me is
the #twitter feed on czo, which only has 80 subscribers,
but which gets more traffic than our #integrations
stream (with 16k subscribers). I would rather
see #twitter win the tiebreaker (if it even got
to the tiebreaker).
The main motivation behind this fix, though, is
to break our dependency on peer_data, which has
some upcoming changes that will introduce some
performance tradeoffs, and I want one less place
to audit.
Also, it will be easier long term to share this
code with mobile if we don't require mobile
to pull in our peer_data dependency. (The webapp
has different forces than mobile that dicate
our data structures.)
The spinner icon is not visible until the user clicks on topic_edit_save,
so the space alloted to spinner-icon looks empty for rest of the time.
To improve the design, the spinner icon is only shown when the user
clicks on topic_edit_save.
EmailLogBackend used to create a new EmailMessage and copy
only certain values from the original EmailMultiAlternatives
object. This resulted in the loss of information and made
it harder to test PRs like
https://github.com/zulip/zulip/pull/17121.
So instead of creating a new EmailMessage, tweak and send the existing
EmailMultiAlternatives object.
Depending on PostgreSQL’s query plan, it was possible for the value
condition to be evaluated before the field_type condition was checked,
leading to errors like
psycopg2.errors.InvalidDatetimeFormat: invalid value "stri" for "YYYY"
DETAIL: Value must be an integer.

This isn't quite the right model, because we're not actually going
through the upload code path, but it does at least provide some inline
image previews in the data.
Fixes part of #14991.
The changes are as follows:
• Fix one day offset in all western zones.
• Correct CST from -64800 to -21600 and CDT from -68400 to -18000.
• Disambiguate PST in favor of -28000 over +28000.
• Add GMT, UTC, WET, previously excluded for being at offset 0.
• Add ACDT, AEDT, AKST, MET, MSK, NST, NZDT, PKT, which the previous
code did not find.
• Remove numbered abbreviations -12, …, +14, which are unnecessary.
• Remove MSD and PKST, which are no longer used.
Hardcode the dict and verify it with a test, so that future
discrepancies won’t go silently unnoticed.

We haven't actively used this plugin in years, and so it was never
converted from the 2014-era monitoring to detect the hostname.
This seems worth fixing since we may want to migrate this logic to a
more modern monitoring system, and it's helpful to have it correct.
Commit e941ee4a15 (#16680) incorrectly
converted this from 775px to xl-max = 1199px instead of md-max =
767px, causing misplacement of the FRB for browser widths between
these values.

We use day_old calculated based on day instead of hours to
render last seen values. This fixes us incorrectly quoting
anything 24 - 48 hours ago as Yesterday and
incorrectly quoting `time` that are Yesterday
but < 24 hours ago in 'x hours ago' format.
We were adding `expanded` class to left-sidebar when searching
for streams even if the left-sidebar was not in the popover state.
This cased confusion with popovers.any_active returning true,
when actually it is not.
We explicitly bind `this` to MessageState class which otherwise
was defaulting to `window`.
This resulted in variables like `this.received` and `this.local_id`
being incorrectly interpreted by called function
as `window.(received | local_id)` which are `undefined`.
Hence, frontend thinks that the message was never received.
It was noticed since this was the common log message when
a double message send bug was observed. This change in no
was indicates fixing of the double send bug, but is hopefully
one step forward in that direction.
