This data structure has never been one that we actually render into
the DOM; instead, its role is to support clicking into view that
contain muted streams and topics quickly.
This downgrade makes that situation much more explicit, and is also
useful refactoring to help simpify the upcoming changes in #16746.

This is a mostly verbatim extraction.
I re-phrased one line of code to work around a lint
false alarm. (Look for `preamble` in the diff.)
There are about 8 lines missing coverage here, so
the new module might be a good candidate to get
100% line coverage on.
Before this change, you would need to remove 74
edges from our dependency graph to make it
acyclic. Now it's 72.
Previously, the `muting_enabled` property of
MessageListData class was used to indicate whether
some messages in the message list need to be
filtered due to topic muting, depending on the
narrow. For example, we exclude messages belonging
to muted topics from stream narrows, but not from
search narrows.
The name `muting_enabled` is a bit confusing, and hence is
changed to `excludes_muted_topics`.
It is also important that the name be specific, since
a similar new property will be added for user mutes
in future commits.
The changes made in this commit are as follows:
* The `remove_messages` is moved to the `message_events.js`
file from `ui.js`.
* We refactor `MessageListData.change_message_id` to no
longer require an `opts` parameter as this function
just returns whether we need to rerender or not.
The blueslip error block can be removed since we made
the change to no long defer the data updates in
commit 3b5ba6b2c1,
this case can no longer occur.
The changes made in this commit are as follows:
* We remove the now unused `ui.find_message` which was added
in commit 1666403850.
* We change the function paramter to now accept message ids
instead of messages to eliminate redundant message ids to
message convertion as only the id is required.
* The remove method in MessageListData did not remove the
messages from the hash, it removed only from the items,
this fixes it.
* This commit also fixes a bug where messages are not added
to the current message list if an event is recieved where
messages are moved to this current narrow.
Only the message removal logic was present, which has been
refactored in this commit.
We were not updating the trailing bookend on deactivation of stream
if the user was narrowed to deactivated stream and this commit fixes
this.
For subscribed streams, we just show the trailing bookend with
content as 'This stream has been deactivated' and hide the
Unsubscribe button.
For unsubscribed streams, we change the content of trailing bookend
to 'This stream has been deactivated' and hide the Subscribe button.
Fixes#15999.
ES and TypeScript modules are strict by default and don’t need this
directive. ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

This is done to decouple our message view related update events
from MessageListData as there are plans to create multiple
MessageListData objects. Instead we update the `stored_messages`
which tracks the complete data for all messages.
Prettier would do this anyway, but it’s separated out for a more
reviewable diff. Generated by ESLint.

Prior to commit 8b7e70ac27 this system
would simply just .hide() forms when they were closed and
.empty().append() every time it needed to "show_edit". This was not a
very clean way of handling the action of canceling an edit, so
8b7e70ac27 introduced a change that had
the "show_edit" function append the form and the "hide" function
.empty() the form.
However, we overlooked the fact that the user could use browser
history to navigate away and back to the form and use "e" or
"left arrow key" to successfully append another form and get to an
ugly, broken state.
This commit does not revert 8b7e70ac27
as it is still accurate to .empty() when hiding the form, but we add
an early exit if a form already exists, to avoid bugs like the above.
Using an early exit instead of eg .empty().append() ensures that the
user doesn't accidentally lose the entire content of an edit, if they
deselect the input box and press `e`.
Fixes: #15045.
The reason for this change is that, this is where `Filter` and
actual tracking of what messages are contiguous lives. This
will be beneficial when we will to move to a model where we
cache `MessageListData` objects for a large number of views.
It is more semantically accurate to remove these elements instead of
just hiding them. We were previously using a .empty().append() chain
during creation/display of these forms, hence, we clearly don't desire
to preserve the element anyway (neither are there any worthwhile
benefits of trying to).
If a non-author user clicked on view source in a poll and then close it,
the edit question icon would incorrectly get visible. This made changing
the question in local echo possible for non-author users.
Fixes: #14299
This is not always a behavior-preserving translation: _.extend mutates
its first argument. However, the code does not always appear to have
been written to expect that.

This commit was originally automatically generated using `tools/lint
--only=eslint --fix`. It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

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 makes the "more topics" option which appears below the list of
known topics in the left sidebar appear only when it's possible there
are actually more topics to be displayed. Two specific cases it
resolves completely include:
* Newly created realms; this widget was a common source of confusion
for new organization administrators.
* Newly created streams.
There are still some corner cases this doesn't handle, e.g. if you
just joined a private stream with protected history, but there isn't
as easy a fix for those.
Essentially rewritten by tabbott to fix code duplication and comment
extensively.
Fixes#10265.
We recently added a feature to warn users that they
may need to scroll down to view messages that they
just sent, but it was broken due to various complexities
in the rendering code path.
Now we compute it a bit more rigorously.
It requires us to pass some info about rendering up
and down the stack, which is why it's kind of a long
commit, but the bulk of the logic is in these JS files:
* message_list_view.js
* notifications.js
I choose to pass structs around instead of booleans,
because I anticipate we may eventually add more metadata
about rendering to it, plus bools are just kinda brittle.
(The exceptions are that `_maybe_autoscroll`, which
is at the bottom of the stack, just passes back a simple
boolean, and `notify_local_mixes`, also at the bottom
of the stack, just accepts a simple boolean.)
This errs on the side of warning the user, even if the
new message is partially visible.
Fixes#11138
