This defers O(N*S) operations, where
N = number of streams
S = number of subscribers per stream
In many cases we never do an O(N) operation on
a stream. Exceptions include:
- checking stream links from the compose box
- editing a stream
- adding members to a newly added stream
An operation that used to be O(N)--computing
the number of subscribers--is now O(1), and we
don't even pay O(N) on a one-time basis to
compute it (not counting the cost to build the
array from JSON, but we have to do that).
Webpack code splitting will make the inclusion order of CSS files less
obvious, and we need to guarantee that these rules follow the rules
they override.

This moves our main CSS for rendered Zulip message content into an
external file, which may be reusable but in any case should make it
easier to find this content.
We had several patches to spectrum, but the only essential one
(0ea770fc18) had already been fixed upstream,
and another was just handling jQuery deprecation warnings for not yet removed features.
See #12749 for details.

It seems like the de facto standard ES polyfill library these days,
and we already depend on it through simplebar.

Moving bootstrap-typeahead from bundles/commons.js to bundles/app.js
and csrf.js from bundles/app.js to bundles/commons.js makes
bundles/commons.js equivalent to the "common" bundle, so we can
replace the latter with the former.

The minimal syntactic sugar it might provide isn’t worth the
unexpected side effects (including side effects on third party
modules).
For now, we allow zrequire to emulate the previous syntax in the Node
test suite, even though stealing part of the NPM namespace is
confusing.

perfect-scrollbar replaces both the appearance and the behavior of the
scrollbar, and its emulated behavior will never feel native on most
platforms. SimpleBar customizes the appearance while preserving the
native behavior.

This commit adds `stream_ui_updates.js` module. This module
will includes functions which will update different ui elements
(i.e. subscription button, subscriber count).
This is a pure code move.
We want to use user circles in the left sidebar,
so this code will no longer belong in
right-sidebar.scss.
This code is just related to drawing the circles.
We can still position in size in other CSS files
(with more context-specific selectors).
This adds a new realm_logo field, which is a horizontal-format logo to
be displayed in the top-left corner of the webapp, and any other
places where we might want a wide-format branding of the organization.
Tweaked significantly by tabbott to rebase, fix styling, etc.
Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.
Fixes#7995.
We move all of its logic into settings_sections.
Note that this is slightly more than a refactor.
We are slightly more aggressive about resetting
sections. For example, if you go into Settings,
then exit the overlay, then go into Manage
Organization, we will now reset sections for both
groups.
This small modules nicely breaks down the
responsibilities of topic_list and stream_list
when it comes to zooming in and out of topics
(also known as hitting "more topics" or "All
Streams).
Before this, neither module was clearly in
charge, and there were kind of complicated
callback mechanisms. The stream_list code
was asking topic_list to create click handlers
that called back into stream_list.
Now we just topic_zoom set up its own click
handlers and delegate out to the other two
modules.
This module makes it really easy to create are-you-sure
dialogs for dangerous operations.
Basically it's one function with five parameters. You
give three chunks of HTML, a callback function, and
a parent container.
The first use of this will be in settings_user_groups,
coming up in a couple commits.
This is part of work to break some of our
nastier circular dependencies in preparation
for our es6 migration.
This commit should facilitate loading leaf-like
modules such as people.js before all of the things
that reload.js depends on.
We add a padded div to our container for the buddy
list to give scrolling the illusion that we've
rendered every list item, while still letting
the browser do the heavy lifting instead of trying
to fake it out too much.
We probably should have done this a while ago, even
though these functions are pretty tiny. The goal here
is to make it easier to have more consistent search
semantics.
Our first use case is subs.js. In this case we
are able to decouple a bit of generic string
matching from the subs-specific code.
Also adds the file to the static asset pipeline.
search_pill_widget.js will be used to access the pills object for
the search query box. It will act in a similar way to
compose_pm_pill.js. Why is this needed: Consider you've initiated
a pills object in search.js for the search query box. Now you want to
also access that pills object to pre-populate pills after a reload in
hashchange.js. search_pill_widget.js makes this easy without the use
of events.
This commit moves all files previously under the 'app' bundle in
the Django pipeline to being compiled by webpack under the 'app'
entry point. In the process, it moves assets under the app entry
to a file called app.js that consumes all relevant css and js files.
This commit also edits the webpack config to be able to expose certain
variables for third party libraries that are currently required by
some modules. This is bad coding form and should be refactored to
requiring whatever dependencies a module may have; we're just
deferring that to the future to simplify the series of transitions we
need to do here. The variable exposure is done using expose-loader in
webpack.
The app/index.html template is edited to override the newly introduced
'commonjs' block in the base template. This is done as a temporary
measure so as not to disrupt other pages on the app during the transition.
It also fixes the value of the 'this' context that was being inferred
as window by third party libraries. This is done using imports-loader
in the webpack config. This is also messy and probably isn't how we
want things to work long term.
