We now let color_data keep its own state for
unused_colors, so that we longer have to pass in
a large list of unused_colors every time we want
to assign a new stream color.
This mostly matters at startup, where we might
be cycling through 5000 streams. We claim all
the unused colors up front.
Each operation now has an upper bound of expensiveness,
where the worst case scenario is basically popping
off the first element of a list of <= 24 colors.
The algorithm is now deterministic, too, to make
it easier to test. It's unclear whether random color
assignment ever had much benefit, and it made unit
testing the algorithm difficult. Now we have 100%
line coverage.
Fixes part of #10902.
We move remove_deactivated_user_from_all_streams
into stream_events.js. There were some minor changes
to rename variables and also to not rely on using
`stream_info`.
This allows several modules to no longer need
to import `narrow` (or, in our current pre-import
world, to not have to use that global).
The broken dependencies are reflected in the node
tests, which should now run slightly faster.
We move some data code from subs.js to stream_data.js.
It's not clear we have been using the optimal sort for
dealing with locales, but this change preserves the
current behavior. The only subtle change here is that
we look up subs using a Dict now instead of a plain
JS object.
These were resulting in inadvertant calls to blueslip.fatal but
the code continued beyond that point, since in our testing environment
we do not stop executing when fatal is called.
This commit also adds checks to ensure that the subs were created.
Now that we've moved it into a bulleted set of options inside a modal,
there's no good reason to have separate variables for the corner cases
around who can manage a stream.
Partially fixes#4708.
Implements a first version (v1) for the feature. The next step would be
to allow admins to toggle `is_announcement_only` in the UI.
This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests. (The latter goal has some
complications, since we often intentionally leak
setup in tests.)
If notifications_stream is private and the current user has never been
subscribed, then we would throw an exception when trying to look up
notifications_stream. In this situation, we should just treat it like
the stream doesn't exist for the purposes of this user.
Currently, stream subscriptions aren't getting updated without
hard reload when user is deactivated in realm.
Fix this issue by updating stream subscription widgets on user
deactivation event.
Fixes#5623
In stream settings, if user add subscriber to unsubscribed public
stream from `Add` input widget it gives lots of blueslip warnings,
cause user isn't subscribed to public stream.
Fix this by changing condition to `sub.can_access_subscriber` from
`sub.subscribed` in blueslip warning, cause user can access
subscribers in such cases even if not subscribed to stream.
Tweaked by tabbott to make the node tests pass.
Private streams were not included in stream suggestions for default streams
in org settings.
Remove function, which exclude private streams from stream suggestions
for default streams.
This mostly moves code, and it also removes some unnecessary
coupling to stream_data.js. The topic_data code purely
works in the stream_id space, so there's no need to set up
actual stream data for it.
We now call topic_data.add_message() and
topic_data.remove_message() when we get info about
incoming messages. The old way of passing in a boolean
made the calling code hard to read and added unncessary
conditional logic to the codepath.
We also have vague plans to change how we handle
removing topics, since increment/decrement logic is now
kind of fragile, so making the "remove" path more explicit
prepares us to something smarter in the future, like just
figure out when the last topic has been removed by calling
a filter function or something outside of topic_data.js.
Another thing to note here is that the code changed here
in echo.js is dead code, since we've disabled
message editing for locally edited messages. I considered
removing this code in a preparatory commit, but there's
other PR activity related to local echo that I don't want
to conflict with.
One nice aspect of removing process_message() is that
the new topic_data.js module does not refer to the legacy
field "subject" any more, nor do its node tests.
This commit introduces a per-stream topic_history class
inside of topic_data.js to better encapsulate how we store topic
history.
To the callers, nothing changes here. (Some of our non-black-box
node tests change their way of setting up data, though, since the
internal data structures are different.)
The new class has the following improvements:
* We use message_id instead of timestamp as our sorting key.
(We could have done this in a prep commit, but it wouldn't
have made the diff much cleaner here.)
* We use a dictionary instead of a sorted list to store the
data, so that writes are O(1) instead of O(NlogN). Reads
now do sorts, so they're O(NlogN) instead of O(N), but reads
are fairly infrequent. (The main goal here isn't actually
performance, but instead it just simplifies the
implementation.)
* We isolate `topic_history` from the format of the messages.
This prepares us for upcoming changes where updates to the
data structure may come from topic history queries as well
as messages.
* We split out the message-add path from the message-remove
path. This prepares us to eventually get rid of the "count"
mechanism that is kind of fragile and which has to be
bypassed for historical topics.
This new module tracks the recent topic names for any given
stream.
The code was pulled over almost verbatim from stream_data.js,
with minor renames to the function names.
We introduced a minor one-line function called stream_has_topics.
We now have all of our callers into recent_topics code just
receive a list of topic names from get_recent_topic_names().
This is more encapsulated than handing off tiny little
structures to the three callers, two of whom immediately
mapped the objects to names, and one of whom needlessly
used the now defunct name canon_subject field.
The consolidation here removes some "subject" references, and
now all lookup are by stream id, not stream name.
The diff here is a bit daunting, but it's mostly simplification
of tests and calling code. Two of the callers now need to look
up stream ids, but they are otherwise streamlined.
The main change here is to stream_data.js, and we replace the
`canon_subject` and `subject` fields with `name`.
The node tests have purged modules from cache that were
included via things like set_global(), but calling require
directly would leak modules into the next test, which made
a couple tests only work when you ran the whole suite. I
fixed those tests to work standalone. And then I now make
dependencies explicitly clear the require cache before we
require them in namespace.js.
This commit changes the key for recent_topics to be a
stream id. For streams that have been renamed, we will now
get accurate data on recent topics and active streams as
long as stream_data.get_stream_id(stream_name) returns a
valid value.
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.
This is not a user-facing change, but it starts us down the
path to having the JS client be able to look up old stream
names for situations like people clicking old external links
or for live-update scenarios.
