When we change a stream name, we now use the stream id as the
key to find messages we need to live update. This eliminates
some possible race conditions from two users renaming a stream.
This commit introduces message_live_update.js.
The new call stack is this:
subs.update_subscription_properties
subs.update_stream_name
message_live_update.update_stream_name
message_list.update_stream_name
In the new stream creation modal, added checkboxes for each stream
and a toggle to see or hide the checkboxes. Altered filtering to
filter streams and users. Added corresponding casper tests.
When a stream is checked/unchecked, it does not affect the state
of any user checkbox. This may be visually unclear as users can be
added even if their checkboxes are empty.
Fixes#2448
This is a major change to the /#subscriptions page, converting it to
by a side-by-side list of streams and their settings in an overlay.
There are no new features added/removed, but it's a huge changeset,
because it replaces the old navigation logic and moves the stream
creation modal to appear in the right side of this overlay.
This is more performant, along with accepting a parameter for
filtering only streams that are subscribed to if the toggle is set to
subscribed only.
Also, it now does substring matches, rather than just matching if an
entire word matches the search query.
Fixes#2141.
From subs.js we don't redundantly try to remove an element
from ths sidebar; we just trigger the event.
In stream_list.js we continue to remove the element from
the DOM, and we also remove the widget from our internal
Dict of sidebar rows, so that if we re-subscribe, we know
we'll automatically re-build the widget from the template
and the latest data from stream_data.js.
We now use stream_id as our key to rename streams, which
should prevent a few race conditions long term. (We are
still possibly contending with other events that use
stream_name as a key, so this is not perfect.)
We don't want to prepend new subscribers to our list of
subscribers in the settings page when they hit enter; we
want to wait till we get the event from the server.
This is a fairly new regression that was added when we
live-updated peer subscriber changes.
This fixes and issue where the change_stream_privacy template had its
own duplicate copy of the data-stream-name attribute, which wasn't
updated when streams were renamed.
Fixes#2016.
