We've had for years a subtle bug, where after editing a topic in the
left sidebar that had previously had unread messages (but doesn't
anymore), the old topic might still appear in the sidebar.
The bug was hard to notice except for new organizations or in the
development environment, because the pre-edit topic appeared with a
sort key of -Infinity (that being the max ID in an empty list of
message IDs). But this is an important onboarding bug in reducing
faith in Zulip's topic editing just working, so I'm glad to have it
fixed.
Fixes#11901.
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 breaks an indirect dependency of stream_data
on the channel module.
It's a verbatim code move, apart from the one-line
helper `has_history_for`. It's not totally clear
to me why the original code doesn't call into
`is_complete_for_stream_id` to early-exit, but
figuring that out is outside the scope of my
change.
It's possible that we will eventually just subsume
this tiny module into topic_list once we finish
breaking all dependencies, but we may want to
reuse this for something like Recent Topics
or other similar UIs.
It's also possible that we'll want to rename
stream_topic_history -> stream_topic_history_data
sometime soon, possibly after we clean up its
dependency on message_util soon.
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.

After the latest message in a stream is deleted, we should update
the max_message_id in the stream.
Removed false comment in message_util.get_messages_in_topic
this method only takes 2ms for 10,000 messages loaded locally.
Fixes#15992.
If the last message of the topic was deleted, we update the stored
message_id in the topic history so that the topic order in topic_list
is updated correctly.
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.

Prettier would do this anyway, but it’s separated out for a more
reviewable diff. Generated by ESLint.

Fixes#15285
This event will be used more now for guest users when moving
topic between streams (See #15277). So, instead of deleting
messages in the topic as part of different events which is
very slow and a bad UX, we now handle the messages to delete in
bulk which is a much better UX.
This adds a way to keep track of max_message_id of a
stream and fetch it using the method get_max_message_id().
This will be useful for sorting streams by most recent
activity which will be implemented in the upcoming commit.
Essentially rewritten by tabbott to have a coherent tracking system,
and provide documentation.
Part of #10794.
In ee0d4541b4, we renamed the topic_date
-> stream_topic_history, and in the process renamed some local object
properties from .name => .topic_name, and accidentally change the
type for the data from the server as well.
The test fixtures were incorrectly migrated in the same way, so we fix
that as well.
`stream_topic_history` is a more appropriate name as this
module will contain information about last message of a
stream in upcoming commits. Function and variable names
are changed accordingly like:
* topic_history() -> per_stream_history()
* get_recent_names() -> get_recent_topic_names()
* name -> topic_name
