This is a fairly risky, invasive change that speeds up
stream deactivation by no longer sending subscription/remove
events for individual subscribers to all of the clients who
care about a stream. Instead, we let the client handle the
stream deactivation on a coarser level.
The back end changes here are pretty straightforward.
On the front end we handle stream deactivations by removing the
stream (as needed) from the streams sidebar and/or the stream
settings page. We also remove the stream from the internal data
structures.
There may be some edge cases where live updates don't handle
everything, such as if you are about to compose a message to a
stream that has been deactivated. These should be rare, as admins
generally deactivate streams that have been dormant, and they
should be recoverable either by getting proper error handling when
you try to send to the stream or via reload.
This makes the subscriptions page responsive by having the settings tab
slide over when a user taps on a stream, giving almost the whole screen
to view the settings.
When filtering streams, we were incorrectly treating the regexp input
provided by the user as a regular expression, meaning that terms like
`c++` would trigger errors because they are invalid regular expression
syntax. We fix this by replacing RegExp with a simple IndexOf check.
Node test added by tabbott.
Fixes#3559.
This changes all references of the data-stream-name to more
predictable data-stream-id references in the subscriptions overlay.
This prevents unescaped characters from breaking selectors and stream
renames from breaking selectors.
This change makes it so that when you are creating a stream
and use "Copy from Stream", the UI will immediately
check/uncheck the user checkboxes that correspond to the
stream's subscribers.
In concrete terms this allows Cordelia to create a new
stream call "Paris" that has all the "Verona" subscribers
except for Hamlet.
It also makes it so that when you go to create the stream,
the response is a little quicker, because we don't have to
iterate the streams.
Finally, it removes an odd quirk from the original design,
where if you clicked on Denmark but then collapsed the
streams, we wouldn't actually add the Denmark subscribers
to your new stream.
The current UI will still be slightly intuitive for people, as
I think checkmarks don't really make sense here. What we
really want are Add/Remove links (or buttons) next to each
of the existing streams.
I moved the UI element for "Copy from Stream" to be above
the list of users, including the filter box and check/uncheck
links, which no longer get applied to the list of streams.
The reason I no longer apply the filter to streams is...
* It's kind of confusing to have filters apply to both
streams and users. There should be separate filters for
them, and I will try to resuscitate that feature later.
* The code to filter the streams was doing a sketchy
regex operation against user-inputted data. (`match()`)
* We want to use the same stream filtering code as the
right sidebar uses.
* It improves performance for the common case that you
are filtering users.
The reason I no longer apply the check-all/uncheck-all actions
to streams is that it would be crazy to select all your streams
to copy users from, and it would be expensive/slow for large
realms, and it would likely be done by accident if somebody was
trying to manage individual users.
Finally, the check-all/uncheck-all actions have been scoped
to the users filtered by the text box, so I moved the links
under the text box to make that hopefully more clear to users.
If we blank out the user filter for users (by hitting backspace,
for example), then we now have short-circuit logic to display all
the user checkboxes. (The user-facing behavior doesn't change here,
but now we don't have to process all the strings.)
The function people.filter_by_search_terms() used
to return a JS object with emails as keys to represent
a set of users. Now we return a Zulip Dict() object
with user_ids as keys.
The old implementation was O(N squared) for N = number of
users due to its using an O(N) selector inside of a loop.
Now we simply iterate through all the checkboxes and turn them
on or off based on a bunch of O(1) operations.
When we subscribe ourselves using the "Add" button in the
right pane of "Stream settings", we now call
stream_data.subscribe_myself(), which properly updates our
data structures (more than just sub.subscribed) and prevents
some console errors when you un-subscribe yourself using
the check mark.
This change makes it such that the stream filtering operation will only
run if the subscription overlay is visible, preventing any issues with
the lack of existence of elements or processing something that users
won’t be able to see.
Fixes#3388.
The new subs.close() function should unify all closing events of the
subscriptions overlay. The function also now tracks whether the
subscription overlay is in a closed or open state.
- Change `stream_name` into `stream_id` on some API endpoints that use
`stream_name` in their URLs to prevent confusion of `views` selection.
For example:
If the stream name is "foo/members", the URL would be trigger
"^streams/(?P<stream_name>.*)/members$" and it would be confusing because
we intend to use the endpoint with "^streams/(?P<stream_name>.*)$" regex.
All stream-related endpoints now use stream id instead of stream name,
except for a single endpoint that lets you convert stream names to stream ids.
See https://github.com/zulip/zulip/issues/2930#issuecomment-269576231
- Add `get_stream_id()` method to Zulip API client, and change
`get_subscribers()` method to comply with the new stream API
(replace `stream_name` with `stream_id`).
Fixes#2930.
When filtering users in the new stream form, check all
and uncheck all will only effect those users who are filtered,
visible in the dom.
Includes a Casper test for the new condition.
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.
