Processing 1k messages takes roughly 1s on a live server like
chat.zulip.org, which is a good enough duration after which
user will be looking to get some feedback on the request. Once
we show the in-progress banner, it makes sense to do bigger
batches to speed up the process.
As detailed in the comment, the new "mark all as read" bankrupcty code
path would fail to mark as read muted stream messages that are older
than the oldest unread non-muted message.
This was because of the semantics of the `first_unread` anchor value
being actually "fire unmuted unread".
We can just change this to "oldest", because we're already using an
`is:unread` for the narrow query; doing so likely is a small
optimization, since we save the query to compute the first unread.
This matches the current bulk-operation behavior of the message lists,
and avoids spending an enormous amount of time adjusting unread counts
once per message in a loop over thousands of messages.
Also add some comments on adjacent code paths.
Fixes#23406.
Fixes#14053.
This also uses the new alert banner system.
It is not clear if we want to scroll user to the end of the narrow
after this update is complete. There is a "scroll to bottom" button
for users who want to be placed at the end of the narrow but there
is no reverse option for users who don't. So, maybe not changing
the scroll position is preferred especially since we now use
banners for the update where a user could have been reading something
while we were updating the message flags in the background.
We do not handle the case of `mark as read` and `mark as unread`
both running in batches at the same (This is a somewhat rare case
given the high cap on `NUM_OF_MESSAGES_UPDATED_PER_BATCH` but
possible.).
`unread.declare_bankruptcy` is no longer used in the code but
we keep it since it is used extensively in tests.
Previous algorithm was not correct if we didn't have full data for
the current narrow loaded from the server. #23512 adds the support
to mark messages in a narrow unread after a give message_id.
Added a new alert banner to indicate loading and success states of
an ongoing request. This is useful when requests can take a long
time to complete.
When processing an "update_message_flags" event to mark messages
as unread, check the current message list once messages are updated
to see if the `mark_as_read_turned_off_banner` should be visible.
This means that other clients in a view that also does not mark
messages as read (for example a sender or keyword search narrow)
will also load the banner when the view is updated.
Fixes#23502.
In theory, this function should never be called when Recent Topics is
visible. But if it somehow is, ensure that we don't access
message_lists.current without first checking whether it's visible.
This was added by commit 7f174213ed, and
appears to have been designed for responses that are *successful* but
falsy. Logically, these should not implicitly represent a failure to
be retried if it were.
Note from tabbott: The background is that this idempotent retry loop
was a hacky workaround for a bug we never understood but saw daily in
production. Especially during server restarts / client reloads,
something would result in 200 responses with no data being seen by the
frontend, despite the Django server not having received/processed the
request. Fortunately, this strange failure mode appears to have
stopped happening in late 2019, so we can delete this hack.

This commit adds the backend functionality to
mark messages as unread through update_message_flags
with `unread` flag and `remove` operation.
We also manage incoming events in the webapp.
Tweaked by tabbott to simplify the implementation and add an API
feature level update to the documentation.
This commit was originally drafted by showell, and showell
also finalized the changes. Many thanks to Suyash here for
the main work here, which was to get all the tests and
documentation work moving forward.
Notifies user when messages are not being marked as read through a
banner that lets them mark all messages in the narrow as read. Note
that the banner is only displayed if the user's actions, like
scrolling, would've actually marked the messages as read.
This avoids distracting the user when viewing a thread they've already
read.
tabbott has verified that if new messages come in, the banner will reappear.
Fixes: #18768.
There are a few instances where we check if messages can be marked
read and mark that list as read when scrolled to bottom. Using
this would be nicer and also this function can be extended later to
display a banner when messages are not being marked.
We split recent_topics module into recent_topics_(ui + data + util).
This allows us to reduce cyclical dependencies which were
created due to large list of imports in recent topics. Also, this
refactor on its own makes sense.
We also add a check to see if `message_feed_container` is visible,
since it is possible that recent topics could be visible which
was not a possibility when this logic was written.
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.

ES and TypeScript modules are strict by default and don’t need this

remove it from ES and TypeScript modules.

Since the pointer is no longer used to set the browser's position, we
no longer need this complex code to send updates to the server during
the bankruptcy flow.
Messages are automatically marked read when all the messages in
the current narrow are visible. While this is handy, this is
should not happen when any of the overlays are open.
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.

Apparently, we didn't have one of these, and thus had a moderate
number of generally very old violations in the codebase. Fix this and
clear the ones that exist..
