On receiving a `peer_add`/`peer_remove` event we were performing a
subscribers list re-rendering even when the stream settings form was
not open which was causing a traceback. This commit fixes this behavior
by first checking if the corresponding stream settings form is open and
performs a re-rendering only when it is open.
We were incorrectly amending the HTML directly whenever a subscriber
was added/removed. For updating any list which is being managed by
`list_rendering.js`, instead of modifying the HTML directly we should
just update the data in list render instance and perform a re-render.
Fixes: #4812.
We used to render the subscriptions_settings template for every
stream when you loaded "Manage Streams," which can be very slow
for a big realm. Now we only render the right pane on demand.
The function stream_data.add_admin_options() got removed as
part of a somewhat recent fix. This caused a console error, and
the modal would not go away.
We now call the new stream_data.update_calculated_fields().
This commit only addresses the recent regression. We still have
the known issue that public/private changes do not get
live-updated for other users.
This is one of the last major endpoints that were still done in the
pre-REST style.
While we're at it, we change the endpoint to expect a stream ID, not a
stream name.
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.
This code makes the right pane work in "Manage Streams" when
you are editing a stream subscription. It handles basic
functionality (submitting forms, etc.), live updates, and
showing the pane as needed.
Most of the code here was simply moved from subs.js, but some
functions were pulled out of larger functions:
live update:
add_me_to_member_list
update_stream_name
update_stream_description
collapse/show:
collapse
show_sub
We also now export subs.show_subs_pane.
We eventually want stream_edit not to call into subs.js, and
this should be fairly easy--we just need to move some shared
methods to a new module.
