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.
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.
