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.
Previously, when a new stream was created on a client other than the
current one, the browser would first receive the "stream_created"
event, and make up a client-side display color at that time to use in
the "stream settings" view (it doesn't yet know the color that was
selected when the user was actually subscribed, because it doesn't
even know yet that the user is being subscribed to this stream), and
then moments after it'll receive a "susbcribe" event letting the
client know that the user is subscribed (and specifying the color to
use).
However, due to an argument not being passed through properly and a
missing rerender, we were not properly updating either the data
structures or doing a stream colors rerender in order to show the new
color.
This fixes the issue reported in
https://chat.zulip.org/#narrow/stream/48-mobile/subject/stream.20colors/near/660170
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`.
Previous commits have fully implemented the logic for stream email
notifications; this final commit adds support for configuring it to
the UI.
Fixes#6511.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
This is preparation for enabling an eslint indentation configuration.
90% of these changes are just fixes for indentation errors that have
snuck into the codebase over the years; the others are more
significant reformatting to make eslint happy (that are not otherwise
actually improvements).
The one area that we do not attempt to work on here is the
"switch/case" indentation.
After adding a newly created stream to the top of the stream list,
call to actually_filter_streams in stream_events.mark_subscribed
rerendered the filter_table and the stream list was refreshed. The
call to actually_filter streams was introduced to rerender the
subscriber list but stream_edit.rerender_subscribers_list takes care
of it already.
Fixes#9033.
This migrates what were effectively data update functions to be called
from the main stream_events handlers, instead of being called from the
view-update code in subs.js.
The recent fixes we made to make stream settings update properly when
doing live updates were great, but they would throw an exception if
the stream settings overlay wasn't open. This fixes that by adding
the appropriate check.
We were getting several exceptions in mark_subscribed if the streams
overlay wasn't open, basically because we'd try to filter the
right-side stream list when it wasn't present in the DOM.
Previously it was called before the event was processed by the server
and the subscription was updated to have the user subscribed to a
stream, so there was a race condition that would make it iso that
sometimes the stream line would disappear on the next render pass due
to the event not having completed yet.
This makes it so that the re-render happens after the event is
processed in `stream_events.js`.
Fixes: #6797.
We now return user_ids for subscribers to streams in add-stream
events. This allows us to eliminate the UserLite class for
both bulk adds and bulk removes. It also simplifies some JS
code that already wanted to use user_ids, not emails.
Fixes#6898
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.
We had a bug for a while where if somebody subscribed you to a
stream, and you were narrowed to another stream, we'd show
a button in the "trailing bookend" to "Unsubscribe" from the
current stream. I'm not sure how long we had that bug, but it
was at least a couple months old, and I couldn't track down an
issue for it.
Now we make sure that the stream event for the subscription is
related to the current narrow.
Users should still see messages when they subscribe/unsubscribe
themselves or when another user re-subscribes them to the stream
that they are narrowed to.
Previously, we would let the backend pick a color and send it to the
frontend; then the frontend would ignore that color and pick a
different color and send it to the backend, which would in turn resync
to us.
Fixes#3572.
