In the JS code, we now use `message.unread` universally as
the indicator of whether a message is unread, rather than
the `message.flags` array that gets passed down to us
from the server.
In particular, we use the unread flag for filtering when
you search.
A lot of this commit is just removing logic to add/remove
"read" from `message.flags` and updating tests.
We also explicitly set `message.unread` to `false` inside of
`unread.mark_as_read()` and no longer have `unread.set_flag()`.
(Some of the callers to `unread.set_flag` were also calling
`unread.mark_as_read`, which was updating the `message`
object, so now we just have `unread.mark_as_read` update
the `message` object. And then unread_ops.mark_all_as_read()
was already calling unread.declare_bankruptcy().)
This adds two similar functions to simplify
our batch processing of unread messages.
unread.get_unread_messages
unread.get_unread_message_ids
They are used to simplify two functions that loop
over messages. Before this change, the functions
would short circuit the loop to ignore messages
that were already read; now they just use the
helpers before the loop.
This reverts commit c953759486.
The client side logic for dealing with server counts is actually
fine, as far as we know, but there are still some data-related
issues with cleaning up old unread counts.
The server sends down lists of unread message ids in various
buckets, and we now use those on the client to provide more
complete counts of unread messages.
If you read a message, then got a topic edit for it, we were
adding the message to our data structure of unread stream/topic
messages.
Now we guard against this in unread.update_unread_topics. I
no longer expose an update() method in unread_topic_counter,
since we really want to do the unread check at a higher level
to keep other data structures consistent.
This code adds 'read' to message.flags and sets message.unread
to false.
It's not clear that the boolean message.unread is used in any
meaningful way, but we set it to false to avoid confusion. The
bankruptcy code was not doing this before.
Another quirk that existed before was that you could get two
'read' flags in a message when you declared bankruptcy. It's
also plausible that this could happen if you marked a message
as read via two different ways. It probably did not cause
user-facing bugs, but it would be confusing for troubleshooting.
Fixes#5032.
This function allows us to see whether unread.js thinks a message
id is unread (as opposed to looking at the message itself). This
method is useful when we get notifications from the server that a
message has been read. In the future, we may not actually have
a local copy of an unread message, but we'll still know that it is
unread based on page_params. We'll want to update the data in that
case.
Going forward, we'll want to deprecate message.flags for most use
cases and just use the unread.js data structures to track unread
messages.
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>]
