Previously, if you had the streams overlay open (but no active stream
clicked) while another user edited your subscriptions state, we'd
throw an exception handle the get_events call, because the code for
rerendering the subscribers list didn't consider the possibility that
there was no active stream.
When re-subscribing by way of the "Subscribe" button in the right
side settings panel, the row will now be marked as active to
highlight that the row is still selected and being looked at.
Fixes: #6955.
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.
The current behavior is that when you subscribe to a new stream
the scroll position moves back up to the top because the list updates,
when in reality the user shouldn't notice this, so we record the
previous scroll position and then apply it once the DOM update is
finished before the next paint cycle.
Fixes: #6606.
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.
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.
This new modules handles the UI to create streams. It mostly moves
code from subs.js.
It introduces an API around what used to be called meta.stream_created:
reset_created_stream()
set_name()
get_name()
It only partially moves new_stream_clicked().
This commit forces the files that create modals to create their own
modal closing function instead of creating all of them in the modals
file. These functions are then passed to the modals.close object. This
is intended to remove modals.js's dependencies on these other files.
This is mostly just moving methods out of compose.js.
The variable `is_composing_message`, which isn't a boolean, has
been renamed to `message_type`, and there are new functions
set_message_type() and get_message_type() that wrap it.
This commit removes some shims related to the global variable
`compose_state`; now, `compose_state` is a typical global
variable with a 1:1 relationship with the module by the same
name.
The new module has 100% line coverage, most of it coming
via the tests on compose_actions.js. (The methods here are
super simple, so it's a good thing that the tests are somewhat
integrated with a higher layer.)
Prevent switching of stream rows on pressing arrow key when focussed
on the 'Create stream' section (this would cancel the curren stream
creation flow).
The subscriber data is currently pulled from the web needlessly
when it exists in memory. This processes data returned from
the `stream_data.get_sub_by_id(n).subscribers` and the
`people.get_person_from_user_id(n).email` methods to build the
same list of subscribers that is sent from the server.
Fixes: #4314.
On filling out the name and description for new stream,
and changing the tab (e.g. by clicking on a stream on the left),
then come back to 'Create streams', it should restore stream name
similar to the stream description.
Fix#4311.
This is kinda hacky and probably not how we want this to work
long-term, but I think it's a larger refactoring project to make this
part of the model make sense.
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.
On realms with ``should_list_all_streams() == False``, previously, we
would subscribe a user to a stream, but also incorrectly show the stream
creation dialog.
Instead, we act as if the stream was newly created.
This consolidates all actions to close modals into modals.js and
triggers the correct cleaning/collapsing function dependent on what the
data-overlay attribute is labeled as.
It also ensures these all have an e.stopPropagation().
Fixes#4029.
This fixes the mobile web experience for Chrome on iOS.
Apparently, Chrome-on-iOS silently has a `viewport` module that
overrides and user-defined module by that name, causing all of our
code that accesses the viewport module to not work on that platform.
We fix this by renaming it.
We pass in sub instead of stream_name, to support callers that
already do lookups by stream id.
And then we make the second optional argument be subscribers, since
that is all we were using from the old `attrs` argument.
When possible, we should use get_sub_from_target() instead of
get_stream_name(), not only because it often saves a lookup later,
but it also makes it easier to audit the code for name vs. id
bugs. (When you rename a stream, there can be races where you
use the old stream name instead of the more durable stream_id).
This commit handles the easy cases where the caller directly
wanted the sub, not the name.
Previously the mechanism worked such that the innerHTML was being
appended to directly potentially thousands of times which has horrific
performance implications. By concating all the strings together before
appending to the HTML it all gets rendered in one chunk without forcing
a re-render of previous elements. Performance is ~15x-20x faster now.
Change the remaining "Admin settings" with a button, namely
changing a stream's privacy, to instead be a "[Change]" link
opening a confirmation modal.
Fixes: #3493.
User search for streams will now return results where the stream
description (but not the stream name) include the string in the
user query.
The filtering process first obtains the streams whose names match the
user search query, then sorts and displays them. From the remaining
streams, it obtains streams whose description matches the query and
displays them in sorted order after the name match results. Other
streams are not displayed.
Fixes: #2674.
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.
