The prior implementation was needlessly complex. Both del() and
add() are cheap and idempotent.
With this change we no longer bother to delete a topic from a
dictionary when its last message is mark as read, since it doesn't
really help performance. We add a line to the tests to maintain
100% line coverage.
This class is mostly a thin layer over the dictionary, but it
consolidates all the logic to create lookup keys, which have
to follow the convention of being comma-separated, numerically
sorted user_ids.
This commit changes stream_data.in_home_view() to
take a stream_id parameter, which will make it more
robust to stream name changes.
This fixes a bug. Now when an admin renames a stream
you are looking at, it will correctly show itself to
be un-muted. (Even with this fix, though, the stream
appears to be inactive.)
Some callers still do lookups by name, and they will
call name_in_home_view() for now, which we can
hopefully deprecate over time.
Despite the length of this commit, it is a very straightforward
moving of code from narrow.js -> narrow_state.js, and then
everything else is just s/narrow.foo()/narrow_state.foo()/
(with a few tiny cleanups to remove some code duplication
in certain callers).
The only new functions are simple setter/getters that
encapsulate the current_filter variable:
narrow_state.reset_current_filter()
narrow_state.set_current_filter()
narrow_state.get_current_filter()
We removed narrow.predicate() as part of this, since it was dead
code.
Also, we removed the shim for narrow_state.set_compose_defaults(),
and since that was the last shim, we removed shim.js from the app.
When we process messages for unread counts, we now call
people.pm_reply_user_string() to get a string of user ids,
rather than using emails that may have changed since the
message was originally created.
Before this change, we passed in a hash to get_counts() to
mutate, but now we make the caller responsible for splicing
results into a bigger data structure.
The function now involves no mutation.
This change introduces an unread_topic_counter object
that manages unread counts for streams and topics. Consolidating
all the logic into a single class will set us up to add
logic for dealing with topic counts that includes provisional
counts of unread messages from the server. It also makes
the current code a little easier to reason about.
Most of this change was simply extracting functions, but
I also removed a few unnecessary and inconsistent calls to
`stream_data.canonicalized_name` that preceded our use of
Dict with a fold_case argument.
We now use comma-delimited lists of user_ids for the following
data structures in unread.js:
- unread_privates[<user_ids_string>]
- get_counts.pm_count[<user_ids_string>]
It's been very buggy for a while, has limited usefulness compared with
unread counts, and profiling over the weekend indicates that it's very
slow.

I could not find where we were setting the read flag on messages in
response to a update_message_flags event. This fixes a bug where a
user's read position will not be correctly synced in muted streams. For
muted streams the cursor updates seem to force the client to mark the
messages as read.

This experiment has been disabled for everyone for a while: if we
bring something like this back, it is not likely to be exactly the same,
and will be different enough to require a different implementation.
As it is, the summarization code was making a few code paths (rendering
especially) more complex, and is worth removing for simplicity's sake.

There is a scenario where we call process_read_message()
for a message that we haven't recorded as unread before.
I'm not sure how it happens, but I put back code to
guard against crashing. The regression happened in
5752458c821.

Update get_counts() so that it ignores counts for muted topics
when calculating stream/home unread counts.

The indirection was more confusing than helpful, especially
since the function had side effects, despite its getter-like
name.

After killing off unread_counts.stream, the only field of
unread_counts was "private", so I just made unread_privates.
