We used to have code scattered in multiple places to
calculate things like admin options, preview urls,
subscriber counts, and rendered descriptions for
streams before we rendered templates in the "Manage
Stream" code.
These are all consolidated into a new function
called stream_data.update_calculated_fields().
This is mostly code cleanup, but it also fixes a bug where
the "View Stream" button would not work for a newly created
stream.
When you subscribe to a stream, we now set a newly_subscribed
flag on the object, and we return true during the is_active()
call.
This solves the problem that immediately after you subscribe, you
don't have any messages in the stream, so it would appear active
by our old criteria.
This is still something of a workaround, as once you reload, the
stream will become inactive again, unless other messages come in.
A more permanent solution here would be to have the backend
indicate newly subscribed streams to us (apart from the initial
event), but we may not really need that in practice.
If a url is present in stream description, it will be
rendered as a clickable link under /streams page.
Tweaked by tabbott to use the separate rendered_description element to
avoid duplicate rendering and to live-update.
Fixes#1435.
This adds a button to #subsciption page called "View Stream"
that narrows the user to that particular stream.
This fix involves typical changes to JS/CSS to add new features,
and we also add a "preview_url" field to the sub object in
stream_data.js.
Fixes#3878
If we get invalid events related to stream subscribers, we now
exit earlier to prevent ugly tracebacks. We may eventually
want to upgrade some of these warnings to errors, once we fix some
of our live-update bugs. In particular, we don't yet live-update
users when streams go from private to public, so if you add/remove
subscribers to a newly-public stream that a user still thinks is
private, they will not be able to handle the event through no
fault of the codepath that happens during the add/remove.
(There was a method with the same name before, but it wasn't
being used. The new version will accept stream_id instead
of name, and we will use it as part of deactivating streams.)
Earlier commits removed all uses of page_params.email outside
of people.js, and it turns out we have page_params.user_id, so
we don't even need page_params.email for seeding the data.
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.
* In most cases, eslint --fix with the right comma-dangle settings was
able to update the code correctly.
* The exceptions were cases where the parser incorrectly treated the
arguments to functions like `assert_equal` as arguments; we fixed
these manually. Since this is test code, we can be reasonably
confident that just fixing the failures suffices to correct any bugs
introduced by making changes automatically.
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.)
This function will make it easier to unit test upcoming
changes related to stream counts.
This was mostly moving code, but one change is that we
don't call create_subs() in subs.js any more (which would
have been kind of circular dependency), since the only thing
that it did besides calling a more appropriate function
in stream_data.js was to generate a trigger that was
subsequently ignored and possibly a UI trap, as we don't
want to be messing with the stream sidebar when we go into
the stream settings page.
We now simply call exports.create_sub_from_server_data() for
newly encountered unsubscribed streams (which don't belong in
the sidebar anyway.)
This function used to live in subs.js. It's mostly a code move,
but I simplified the logic to determine whether it's subscribed
not to do a lookup into the same data structure that the sub
already came from.
I also added some tests.
