ESLint won’t convert these automatically because it can’t rule out a
behavior difference arising from an access to a self-referential var
before it’s initialized:

undefined
> let y = (f => f())(() => y);

Because of the separate declarations, ESLint would convert them to
`let` and then trigger the `prefer-const` error.

This feels a bit more semantically appropriate: it more clearly says
"here's some information: there is no (relevant) recipient", rather
than "no information available". (Both `null` and `undefined` in JS
can have either meaning, but `undefined` especially commonly means
the latter.)
Concretely, it ensures a bit more explicitness where the value
originates: a bare `return;` becomes `return null;`, reflecting the
fact that it is returning a quite informative value.
Also make the implementation more explicit about what's expected here,
replacing truthiness tests with `!== null`. (A bit more idiomatic
would be `!= null`, which is equivalent when the value is well-typed
and a bit more robust to ill-typing bugs. But lint complains about
that version.)
It'd already been the case for some while that calling `stop` had the
same effect as calling `update` (previously `handle_text_input`) with
a falsy recipient. With the API changes in the previous few commits,
this becomes quite natural to make explicit in the API.
This was named after when it gets called from the UI, rather than
after what it can be expected to do.
Naming it after what it's meant to do -- and giving a summary line to
expand on that -- provides a more helpful semantic idea for reasoning
about the function. Doubly so for using the function in a different
client with its own UI, like the mobile app.
The main motivation for this change is to simplify this interface
and make it easier to reason about.
The case where it affects the behavior is when
is_valid_conversation() returns false, while current_recipient
and get_recipient() agree on some truthy value.
This means the message-content textarea is empty -- in fact the
user just cleared it, because we got here from an input event on
it -- but the compose box is still open to some PM thread that we
have a typing notification still outstanding for.
The old behavior is that in this situation we would ignore the
fact that the content was empty, and go ahead and prolong the
typing notification, by updating our timer and possibly sending a
"still typing" notice.
This contrasts with the behavior (both old and new) in the case
where the content is empty and we *don't* already have an
outstanding typing notification, or we have one to some other
thread. In that case, we cancel any existing notification and
don't start a new one, exactly as if `stop` were called
(e.g. because the user closed the compose box.)
The new behavior is that we always treat clearing the input as
"stopped typing": not only in those cases where we already did,
but also in the case where we still have the same recipients.
(Which seems like probably the common case.)
That seems like the preferable behavior; indeed it's hard to see
the point of the "compose_empty" logic if restricted to the other
cases. It also makes the interface simpler.
Those two properties don't seem like a coincidence, either: the
complicated interface made it difficult to unpack exactly what
logic we actually had, which made it easy for surprising wrinkles
to hang out indefinitely.
Returning true from this function means we go on to send, or extend
the lifetime of, a typing notification; returning false means we don't.
It's hard to see why having a partially-entered name in the recipient
box should mean we're *more* inclined to send a typing notification to
the set of recipients that are already entered; if anything, it seems
like it should make us *less* inclined to do so. So we're better off
without this conditional.
The conditional was introduced in commit 72295e94b, as part of a
conversion from user emails to user IDs; there, it seems to replace a
condition that went in the opposite direction, returning *false* if
there were any invalid emails in the recipient box. So perhaps it's
just inverted.
Moreover, the (re-)inverted version would also be wrong: if the user
is typing a PM addressed to some users, and they hit send, the message
will go to those users whether or not they have any unconverted text
in the recipients box. So the typing notifications should too.
The real purpose these two callbacks serve is exactly what an ordinary
parameter is perfect for:
* Each has just one call site, at the top of the function.
* They're not done for side effects; the point is what they return.
* The function doesn't pass them any arguments of its own, or
otherwise express any internal knowledge that doesn't just as
properly belong to its caller.
So, push the calls to these callbacks up into the function's caller,
and pass in the data they return instead.
This greatly simplifies the interface of `handle_text_input` and of
`typing_status` in general.
This is intended as a pure refactor, making the data flow clearer in
preparation for further changes. In particular, this makes it
manifest that the calls to `get_recipient` and `is_valid_conversation`
don't depend on anything else that has happened during the call to
`handle_text_input`.
This is indeed a pure refactor because
* is_valid_conversation itself has no side effects, either in the
implementation in typing.js or in any reasonable implementation,
so calling it sooner doesn't affect anything else;
* if we do reach it, the only potentially-side-effecting code it's
moving before is a call to `stop_last_notification`, and that in
turn (with the existing, or any reasonable, implementation of
`notify_server_stop`) has no effect on the data consulted by
the implementation of `is_valid_conversation`.
Users generally don't expect wildcard mentions in muted streams and
topics to be treated as a mention, either for the purposes of desktop
notifications or the unread mention counts.
This fixes the unread mention counts part of the issue.

The previous code for ensuring the sort order of emoji choices was
correct relied on an OrderedDict structure, which isn't guaranteed to
be preserved when passed to the frontend via JSON (in fact, it isn't,

sort_keys=True). Switch it to a list of dictionaries to correct this.

Apparently, the changes in fe2adeeee1 to
fix a Firefox focus bug accidentally had the side effect of removing
the topic text box from the area being considered, resulting in the
escape key no longer working to end the message edit from within that
text box.

Apparently, the Zulip notifications (and resulting emails) were
correct, but the download links inside the Zulip UI were incorrectly

While we're at this, we rewrite the somewhat convoluted previous

This has two purposes:
1. Prevent stupid stacks of diacritical marks from overflowing into

2. Prevent Chrome from collapsing the inside bottom margin with the
.messagebox outside (in a way that Firefox doesn’t).

This closes an HTML injection path via user full names in the emoji

As it turns out, our rerender_the_whole_thing function (used whenever
we were adding messages and discovered that the resulting message list
would be out-of-order) was just broken and scrolled the browser to a
random location.
This caused two user-facing bugs:
* On very fast networks, if two users sent messages at very close to
the same time, we could end up with out-of-order message deliveries,
triggering this code path, which was intended to silently correct
the situation, but failed.
* In some narrows to streams with muted topics in the history but some
recent traffic, the user's browser-cached history might have some
gaps that mean the server fetch we do after narrowing discovers the
history is out-of-order, again triggering the
rerender_the_whole_thing code path.
The fix is to just remove that function, adding a new option to the
well-tested rerender_preserving_scrolltop (which has explicit logic to
preserve the scroll position) instead.
Fixes#12067. Likely also fixes#12498.

This commit fixes an issue where when you click on the sort button of

The problem is we are checking the truthness of meta.sorting_function

extract the reverse operation out of sort() to unclutter the logic.
When a user toggles a setting back to its original value without
saving, we automatically hide the save/discard widget, since
effectively the user has discarded their changes.
The logic has previously incorrectly configured this as returning to
the "saved" state, not the "discarded" state, which caused an
unintentional delay before the widget disappeared (by accidentally
running code that was designed for the save -> saved transition).
While doing this I have fixed a very minor bug that we haven't sent
fadeout_delay argument as 0, but having its value as undefined still
defaults to 0 so there will no impact of this change.

deduplicating code.
- Also, removed `realm-night-logo-section` class as it was redundant.
