For filters that cannot be applied locally, we don't know if the
messages are still a part of the filter. So, we remove the
existing message that were updated and let `maybe_add_narrowed_messages`
treat them all as new messages to the filter.
This fixes the bug where existing messages that were present in
the narrow were not updated.
This commit creates the function warn_if_topic_resolved that checks if
the topic to which the user is composing is resolved or not. First it
checks if the stream exists and then if the topic name starts with the
RESOLVED_TOPIC_PREFIX. If the conditions are true, a warning banner is
shown to the user.
It also shows to the user a button to unresolve the topic, if he has
the permission to do so.
Fixes#20584.
As noted in the TODO that we delete with this commit, we never
implemented live-updated for edit history when moving a message to
another topic.
Implementing this involves somewhat ugly copy-paste of the logic for a
content edit, but structurally is pretty simple.
It also makes #20451 much more visible.
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 were passing new_stream_id as undefined in case of topic
edit as event.new_stream_id is undefined in that case.
We pass the correct stream_id to fix it.
This basically reverts 4bd7ec7c36 and
3a9dfc02e6.
The plan earlier was to have compeletely different codepaths
for user and topic muting, so that we could call seperate
functions in the message list class on receiving the respective
events.
However, this cannot be done, because if we, for example, on
receiving a `muted_users` event, filter `_all_items` based on
just user mutes, and store the result in `_items`, then, that
result may still contain topic-muted messages, which is
undesirable. Hence whenever we filter messages, we must do so
based on both user as well as topic muting.
(The code for the former will be added in further commits.)
So, we will have a single function which will handle updating
the message lists for muting.
Earlier, a user can only mute a topic from its recipient bar but can't
unmute it from there (and in fact we displayed an option to mute even
if the topic was already muted!). This commit fixes that bug and
allows a user also to unmute the topic from its recipient bar.
There are two core issues here;
* We did not have code, an icon, etc. for the "already muted" case in
the recipient bar logic at all.
* We did not rerender messages in !excludes_muted_topics views when
muting state changed.
See: 660475bd0c for background on when
we started only rerendering the streams with excludes_muted_topics
after muting changes. Rerendering of newly muted topics are important
for live rendering if a user is narrowed to that topic itself, which
are essentially all excludes_muted_topics narrows anyway.
Hence, now, we rerender by calling the `rerender` function for muted
topics (which is done just before we update the items for muting via
the function: `update_items_for_topic_muting`).
Tweaked by tabbott to add comments explaining the reasoning and
long-term plans.
Fixes#15223.
When moving a topic within a stream that is deactivated, the stream
may not be present in stream_data. Avoid throwing an exception in
this situation by leaving stream_name as undefined; existing logic
seems to anticipate that as a possibility, so we don't need a broader
change.
Longer term, we may want to just send to clients basic data about
archived streams that the user has access to.
Fixes: #17271
This reduces the complexity of our dependency graph.
It also makes sub_store.get parallel to message_store.get.
For both you pass in the relevant id to get the
full validated object.
This reduces our dependency on message_list code (via
message_util), and it makes moving streams/topics and
deleting messages more performant.
For every single message that was being updated or
deleted, the previous code was basically re-computing
lots of things, including having to iterate through
every message in memory to find the messages matching
your topic.
Now everything basically happens in O(1) time.
The only O(N) computation is that we now lazily
re-compute the max message id every time you need it
for typeahead logic, and then we cache it for
subsequent use. The N here is the number of messages
that the particular sender has sent to the particular
stream/topic combination, so it should always be quite
small, except for certain spammy bots.
Once the max has been calculated, the common operation
of adding a message doesn't invalidate our cached
value. We only invalidate the cache on deletes.
The main change that we make here from a data
standpoint is that we just keep track of all
message_ids for all senders. The storage overhead here
should be negligible. By keeping track of our own
messages, we don't have to punt to other code for
update/delete situations.
There is similar code in recent_topics that I think can
be improved in similar ways, and it would allow us to
eliminate functions like this one:
export function get_messages_in_topic(stream_id, topic) {
return message_list.all
.all_messages()
.filter(
(x) =>
x.type === "stream" &&
x.stream_id === stream_id &&
x.topic.toLowerCase() === topic.toLowerCase(),
);
}
This is a prep commit for implementing mute users feature, which
renames this function to be more specific. This function cannot be
used as-is for user mutes, because for user-muted messages, we always
want to rerender the message list, irrespective of what
`excludes_muted_users` is.
In muting_ui.js, we also remove an unnecessary conditional that is
already handled by update_topic_muting_and_rerender itself.
For messages which we don't have stored locally, we don't update
our data structures. This was actually our behaviour before
59e5f2d8fc, which introduced this
bug.
Not doing this caused a major bug where we ran into errors
moving messages for topics for which we didn't have all
the messages available.
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.

We move the message_store.add_message_metadata function
(and all its dependencies) into a new module called
message_helper and rename the function to process_new_message.
(It does a bit more than adding message metadata, such
as updating our message store.)
We also have a "protected" interface now in message_store,
so that message_helper can access the message store:
update_message_cache
get_cached_message
Because update_message_cache is identical to
the former create_mock_message, we just renamed it
in the tests.
Most callers should use these functions:
message_helper.process_new_message (setting)
message_store.get (getting)
It's slightly annoying that the setter interface
is in a different module than the getter interface,
but that's how you break a bunch of dependencies.
We also extract the tiny message_user_ids class:
user_ids()
add_user_ids()
All the code moves here are pretty trivial, and
the code that was moved maintains 100% line
coverage.
The module name `message_helper` is not ideal, but it's a single
function and it'll save time to just do the topology change now and
leave thinking through the right name to later.
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.
