When navigating "back" or "forward", the left sidebar state
should be restored.
Earlier, "more topics" expanded was not considered a distinct
state.
This commit makes it possible to correctly place you in the
"more topics" view or not, depending on where you were.
Fixes#29548.
Reproducer:
* Go to a stream narrow.
* Scroll up to select a previous message.
* Click on a different stream in the left sidebar.
* Click browser back button, you land at first unread message instead
of your selected message.
Fixed by updating the hash before we render the new message list.
This is no longer required since narrow state is restored by
`reload` library and narrow history restores the narrow pointer
and offset when going back to a view.
Only regression here is we will no longer restore the pointer when
user navigates to the combined feed view without using browser back
button and combined feed view is the default view. This is fixed
in the next commit.
Important changes in this commit:
* We only cache message list for "Combined feed" if it is the
default view.
* We modify existing handling of home message list code so that
it can be used to for any message list that we want to cache
using a new `preserve_rendered_state` variable.
* narrow_state.filter() returns the filter of combined feed view list
instead of `undefined`.
* We start fetching messages from the latest message on app load.
* Messages in all messages data and Recent view are always synced.
* If combined feed view list is not cached, we don't track it's
last pointer, effectively sending user to the latest unread
message always .
It doesn't make sense for us to track a separate current filter when
it should just the be filter of current message list if there is one.
This will reduce possible confusion in the codebase where filter
returned by narrow_state is different from message_lists.current.
As discussed in the new comments, we had a bug where the
system-initiated animated scroll that happens when the compose box
opens as a result of narrowing would race with the internal
rerendering that occurs when the message_fetch request asking the
server for additional data returns.
The correct fix for this is just to open the compose box, if we're
going to do so, before setting the user's scroll position in the
narrowing/rendering process.
This ends up being a UI improvement (in that the compose box is
available for typing a bit earlier) as well as avoiding both the risk
of this race as well as the bad UX of adjusting the user's scroll
position multiple times as part of entering the view.
This does not address an as-yet-unknown bug wherein the animated
scroll that occurs when opening the compose box, when racing with a
background rerender, results in a bogus ending scroll position, though
it's easy to see how that might occur given that rerendering does
clear the DOM briefly.
This will prevent any message we want to select after narrowing
from being offscreen entirely or partially.
Steps to reproduce the bug:
* `./manage.py populate_db -n 3000 --max-topics=2`
* Narrow to a stream and scroll high up.
* Align two recipient bars together with nothing between them.
* Click on the first recipient bar after keeping the selected message
on the second recipient bar.
* You will see that the selected message is not in view.
Some files already were using `noop` in place of `() => {}`.
It's both clearer what it means and is easier to type.
This updates all test files to fully use `noop`, and
adds a shared import from the test lib file.
Since is_visible was refactored to use a variable, these mocks
are not required.
Also, since is_visible return `false` by default, mocking it
to return false is not required.
It did the same thing as handle_narrow_activated when passed the
home_msg_list filter.
We still leave a renamed version for use by the inbox/recent views.
This saves the blue box position as state on the location
in brower history, with `history.replaceState`.
The position is restored when a narrow is activated.
Fixes#20066.
This is logic from 10 years ago (dbc4798594)
that is no longer relevant. It seems like we used to show the
search bar open all the time and only showed the buttons when
there was focus in the search bar. Now we close the search bar
when it's not being used, and no longer need to update button
visibility or disable the search close button.
The `initialize` function registers a click handler, and
previously it was being registered another time each time
one of these calls to `initialize()` happened. The only
other thing that happens in `initialize` is a call to
`render_title_area`, so this commit replaces the extra
calls to initialize with that.
This function will allow us to adjust the codebase to write what it
means semantically -- whether a check is for the message list being
visibly empty, or completely empty.
In this commit, we leave the .empty() method incorrect, because
several other adjustments need to be made atomically with fixing it.
Previously, the unread banner templates just rendered on the contents of
the unread banner. This works fine if we don't want to make changes towards
the parent/container of the contents.
This change introduces a new container to each unread banner templates and
a rename. Thus, we can make unique styling changes to the unread banners
while also bring the structure closer to how it is for compose banners.
After merging #24309, we want to add an additional option to the "mark
messages as read on scroll" setting where we only mark messages as read
on scroll in conversation views.
This helps reduce the amount of import cycles we have in the compose
code path following the migration to a fancier stream input.
`compose_closed_ui.initialize()` was moved further down in the
initialization order because it relies on the dropdown widget
to be defined.
Zulip has long had the behavior that opening a stream or topic via
narrowing automatically scrolled the left sidebar to the conversation,
so that you can see it and adjacent ones readily.
When we moved private messages into the left sidebar, we didn't
implement this similar behavior; this resulted in users having to
manually scroll the sidebar in order to browser private message
conversations.
Fix this by using the standard scroll_util helpers, with some extra
care to expand the heading when going to "all private messages".
Fixes#23609.

This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
