This code is a bit flatter and just preps the data
for a single user. There is never any interaction
between the data for user A and user B, so we can
mostly avoid complicated nested data structures
and do most of the data-crunching on a per-user basis.
We also do an explicit sort of the data before
running it through groupby. The explicit sort
simplifies how we calculate `most_recent_info`
and also avoids needing to add `dt` to an intermediate
data structure.
Finally, when it comes to the individual client data,
the code has relied on the assumption that there is
only one row per client, which I believe to be true,
but now the code is more explicit about that.
The word "status" is vague, and this isn't
actually returning a list, so we now name it
get_presence_response.
I originally was gonna rename this to
get_presence_dict, but there's a function
called get_status_dict that returns a subset
of the response, so I think it's a bit more
clear that this is the bigger dict that
actually gets sent back.
We want to err on the side of server_timestamp being
old, since we may eventually use this to make responses
just include incremental changes, and we don't want a
time window (however small) when we miss presence rows.
The clients will be able to deal with duplicate data
to the extent that the time windows are overlapping.
Also, extracting the other local var here
(for `presences`) will set up a subsequent commit
where we re-format the data for clients with
slim_presence=True.
We avoid complicated code to update unread counts
by just using vdom.js.
One small change here is that if click on "more
topics", we replace it with the spinner instead
of putting the spinner after it. This saves us
a redraw under the new scheme.
In e3ad9baf1d, we introduced yet another
bug where we incorrectly shared event dictionaries between multiple
queues.
Fortunately, the logging that reports on "event was not in the queue"
issues worked and detected this on chat.zulip.org, but this is a clear
indication that the comments we have around this system were not
sufficient to produce correct behavior.
We fix this by changing event_queue.push, the code that mutates the
event dictionaries, to do the shallow copies itself. The only
downside here is process_message_event, a relatively low-traffic code
path, does an extra per-queue dictionary copy. Given that presence,
heartbeat, and message reading events are likely more traffic and
dealing with HTTP is likely much more expensive than a dictionary
copy, this probably doesn't matter performance-wise.
(And if profiling later finds it is, there are potential workarounds
like passing a skip_copy argument we can do).
django-phonenumber-field 2.4.0 adds tighter phone number validation
that rejects +12223334444 for having an invalid area code. This was
reverted in 4.0.0, but django-two-factor-auth still requires <3.99.

Due to try-catch deoptimization, Babel strict mode for…of loops run
about 5× slower in Firefox than Babel loose mode for…of, native
for…of, or forEach (which are all about the same speed). Chrome
doesn’t seem to care.
For some reason we need to explicitly add the core-js Symbol polyfill
near the beginning of the common bundle. Otherwise it gets loaded at
the wrong time and the Casper tests fail.

Babel strict generates more code for [...x] than you’d like, while
Babel loose mode assumes x is an array.

We had a plan at some point to use this to display a phone icon or
something for users who would receive push notifications if you
messaged them. IT's not clear that feature was a good idea in any
case, but it certainly shouldn't be synced as presence data; it would
change >100x less often than the rest of presence and so should likely
be synced differently, maybe as a property on user. So it's best to
delete this prototype.
The “Smileys & People” category has been split into “Smilys & Emotion”
and “People & Body”.
Also, fix generate_sha1sum_emoji to read the emoji-datasource-google
version from yarn.lock, since package.json only gives a version range.

When quoting a message with fenced code blocks without a language,
we used to have ambiguity in which '```' fence terminates the quote.
This commit adds explicitly non-interfering fences, which fixes the
above issue as well as makes the raw message easier to quickly read.
Fixes#12446.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.
It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.
This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.
With many tweaks by tabbott to documentation under /help, etc.
Fixes#13616.
