In very large communities, computing page_params can be quite
expensive. Because we've moved the homepage for communities with web
public streams enabled to be the Zulip app, and it's common for
automation to frequently poll the homepage of a Zulip organization,
we'd like to keep those homepages cheap (as the login pages are).
We address this by prototyping something we may end up wanting to do
anyway -- having the web application do a `POST /register` API call in
order to fetch most page_params, and merging those with the mostly
webapp configuration page_params that we leave in the / response for
convenience.
This exact implementation is messy in a few ways:
* We rely on the assumption that ui_init.initialize_everything happens
before all code that needs to inspect the page_params properties we
are fetching via /register. This is likely mostly true, but nothing
in the implementation enforces it.
* The bundle of ~25 keys that are in page_params ideally would be
considered individually, with some moved to the /register API
response and perhaps others eliminated or namespaced inside a
webapp_settings object.
* It's weird to have the spectators network sequence different that
from logged-in users, and potentially a maintainability risk.
* We might be able to arrange that the initial `/` response be
cacheable, now that we're no longer embedding our metadata inside
it. We've made no effort to do that as of yet.
Despite those issues, this commit solves an immediate problem and will
give us helpful experience with a model closer to the one we'll want
in order to happily support a web client that can be run locally
against a production Zulip server's data.

Previously, we were masking the realm_description raw Markdown with
rendered Markdown, which was a type error.
When we switch to calling /register explicitly in a few commits, this
results in a bug, since the raw Markdown ends up taking priority.
Fix this by just using a different name for this different concept.
This'll be shown only when in a different narrow from what
you're composing to.
Takes care of updating display of the button on moving from
one narrow to another and also on changing inputs. This is
what contributes to majority of js code in this commit.
We are not displaying this for private messages since we do not
have a consistent design for both stream and private compose areas.

Thanks to Vlad Korobov for the icon and for proposing various
designs.
The mobile app was never able to use the shared
version of emoji.js, because, among other problems
with our code organization, the emoji.js module
is strongly based on a mutate-the-data paradigm
that doesn't play nice with React. The way
that we mutate data and violate encapsuation
here is something that we would mostly want to fix
without even trying to shared code with mobile, so
subsequent commits will try to extract some pure
functions into a shared module.
Previously, we were experiencing a regression in the positioning of
the play icon for youtube previews, as such, this commit uses a
previously created `handle_video_preview_mouseenter` to ensure the
positioning is always correct.
This is an ugly way of doing things, because this could be handled
directly through CSS flexbox, however, it is an acceptable temporary
fix.
This commit extracts the logic used to ensure that the play icon is
correctly positioned over the video preview for embedded videos, with
the intention that we can use this to fix a regression in the play
icon positioning for youtube video previews.
It turns out that the bug this call hopes to fix only happens when the
user first loads the page to recent_topics and then navigates to a
view with a message list (any other view), but we'd make this call
every time the recent topics table was hidden.
Hence, this commit makes it such that we only make that call if (1)
the page is loaded to recent_topics and (2) we're switching from
recent_topics to a message list view for the first time. We achieve
(1) via binding a handler via ui_init.initialize_everything and (2) by
binding the handler as `.one`, so that it's unbound after its first
invocation.
Additionally, we use window.requestAnimationFrame to prevent this
forcing the browser to do a reflow unnecessarily.
Combined with other commits in this series, this fixes a major
performance problem when leaving recent topics for another view.
See #20255 for details.
An attacker could maliciously craft a full name for their account and
send messages to a topic with several participants; a victim who then
opens an overflow tooltip including this full name on the recent
topics page could trigger execution of JavaScript code controlled by
the attacker.

We are going to move to this code organization for
managing streams:
stream_create.js
stream_create_subscribers.js
stream_edit.js
stream_edit_subscribers.js
The modules stream_create.js and stream_edit.js historically
manage the entire process of creating and editing stream
data (respectively).
Going forward both will delegate most of the subscriber-specific
pieces to either stream_create_subscribers or stream_edit_subscribers.
The stream_*_subscribers modules will be somewhat similar in
nature, but the way that we manage subscribers at creation time
is a bit different than how we manage subscribers at edit time.
Show/hide scroll to bottom button when the last message is
not visible in the current scroll position.
We adjust the bottom offset of the button based on compose box
height.
Fixes#19862
We save the preferred theme in localstorage so that user doesn't
have to re-select the theme on every reload. Users on slow
computers might see flash of a theme change, if it happens.
This effectively reverts part of
70d444a8eb. While it's correct that we
want to render this bit of Handlebars template early, it was not
correct to move all compose box initialization earlier.
Do the same thing we do with the left/right sidebar container
templates, which is to render them directly in `ui_init.js`.
Fixes#20778.
Called the `decorate` function to update stream color in the compose
box on `change` instead of `blur`.
On clicking on a stream option, the input box for the stream name
remained in focus, hence decorate wasn't triggered on blur. Using
the change event instead, ensures that decorate will be called
anytime the stream is changed.
Fixes: #20871
The old name was confusing, since the contents
of the div aren't just a table, and we have
smaller elements that actually do list a bunch
of subscriptions in tabular format.
This is a fairly straightforward extraction.
It's good to test this with Iago, and then go into
Manage Streams and add/remove subscribers for a stream
like devel.
I copy/pasted two small functions that will soon
diverge from stream_edit. The get_stream_id function
will either use a module variable (since we're
generally only editing subscribers for one stream, and
we already have the singleton assumption with
`input_pill`) or a more strict CSS selector. And then
get_sub_for_target depends on get_stream_id. We may not
always need full subs, anyway, and when we adapt some
of this code for creating streams, things are likely to
change.
I stopped exporting a couple functions that have no
callers outside of this module.
The main entry point for the module is
enable_subscriber_management.
We continue to export invite_user_to_stream and
remove_user_from_stream, which should possibly be just
pulled into their own module to lessen some
dependencies, but they don't have too much baggage,
since they just wrap channel calls.
We refactor the code for user notification settings and realm-level
defaults of notification settings to pass a single object consisting
of container element, settings object, url and for_realm_settings
bool variable, to the functions, instead of passing them as separate
variables.
We refactor the code for user display settings and realm-level
defaults of display settings to pass a single object consisting
of container element, settings object, url and for_realm_settings
bool variable, to the functions, instead of passing them as
separate variables.
This commit changes the behavior of how we show
animated emojis in the buddy list. We now show still
image of animated emoji and when hovered show the
animated emoji.
Fixes#19521
The reason for this was we were not loading extra
parameters while storing the status emoji object.
For this we also need the emoji module to be initialized
early because the right sidebar would need it to display
the status emoji.
For spectators (logged view), we send user_id=0 via page_params.
The people module does not know about this user ID, and so throws the
exception. Earlier `people.get_by_user_id` was not called on page load,
but only when determining settings permissions with `settings_data.user_has_permission`.
But 231c536cad made it so that that function
is always called, so we need to handle the spectator case explicitly.

Because the right_sidebar initialization calls user_has_permission, in
organizations that has a waiting period before users become full
members, and only full members can send invitations, Zulip will throw
an exception on startup.
We use subs as a common variable name for a collection of stream
data structure used in settings, in lot of modules. So this
rename clears a bunch of related shadowed variables.
This commit migrates the `navbar.html` Django template
to handlebars by creating a new file as `navbar.hbs`
within `/static/templates` which is then rendered
using `ui_init` module.
As a part of migration, we also remove the `search_pills_enabled`
and `embedded` parameters from the context attribute as they
are no longer needed now.
Fixes part of #18792.
This commit migrates the `right_sidebar.html` Django template
to handlebars by creating a new file as `right_sidebar.hbs`
which is then rendered using `ui_init` module.
It also removes the tests in `test_home` due to the template
migration, since these elements aren't rendered on the backend
anymore.
We also remove `test_compute_show_invites_and_add_streams*`.
Fixes part of #18792.
This commit migrates the `left_sidebar.html` Django template
to handlebars by creating a new file as `left_sidebar.hbs`
which is then rendered using `ui_init` module.
These are the minor changes introduced by virtue of template
migration -
- The `compute_show_invites_and_add_streams` function now
only concerns with the invite_to_realm_policy.
- Renamed the `compute_show_invites_and_add_streams` function
to `compute_show_invites` due to the above change.
- Fixes relevant `test_home.py` tests due to the above
changes.
Fixes part of #18792.
This commit fixes the bug of always showing
day-mode realm logo when color scheme display
setting is set to automatic but the OS setting
is dark theme. This is because we cannot check
the OS setting on backend and we need to set
the logo url accordingly in frontend only.
So, we remove the logo url computation from
backend completely and instead compute it in
the frontend only.
Fixes#18778.
