I added these hooks in Zulip Desktop 5.5.0; handling these events in
the frontend will let us remove the janky desktop-side fallback code
that uses fake click events on menu items with specific indexes.

Steve asked me to remove this, since the tictactoe game was always
intended as a proof of concept. Now that we have poll and todo
widgets, the sample code for tictactoe has much less value.
We replace the content and type in test_widgets.py to maintain
coverage.
css-loader@4 broke @import statements referencing files with
extensions other than .css, unless those @import statements are
compiled away by another loader. Upstream is more interested in
arguing that such @import statements are semantically incorrect than
applying the one line fix.

We update the pills typeahead logic to also include
stream results and pass the "stream" key in `opts`
to enable this option for the Add subscriber form.
This commit implements the feature of adding all the
subscribers of another stream in the "Add subscribers"
UI, with the help of a new "stream_pill.js` file.
We temporarily add `user_pill.js` to the EXEMPT_FILES
list as typeahead will be set up in `stream_edit.js`
file which does not have any dedicated tests file.
Work towards #15186.
We don't modify bootstrap.js here but override its popover and
tooltip plugins. In future we will not import these plugins
via npm. We also copy all the popover code from bootstrap.css v2.1.1
to popovers.scss since all the code in bootstrap-tooltip.js is
based upon this css or vice versa.
Update THIRDPARTY info about bootstrap libraries.
There were 4 types of changes to bootstrap.js - bugfixes, file
moves, changes to typeahead plugin and changes to tooltip +
popover plugin.
Bugfixes were automatically fixed when upgrading to v2.3.2, file
moves are irrelevant to this upgrade and the plugins were
extracted into separate files.

8f1cee0 - Files moving around
1490ae1 - add file
We move this function from `user_pill.js` to `pill_typeahead.js`.
The function has also been renamed to `set_up`.
The move was made because there are plans to update the pills
typeahead (i.e. to include user-groups/streams in the results).
Thus this function should not belong in `user_pill.js`.
Prior to commit eb4a2b9d4e the center
area of the navbar was based on a structure that appended crumbs or
"tabs" as <li>s, forming a tab_bar and a tab_list.
However, in eb4a2b9d4e we apply a new
style and structure to the navbar which lets go of the convention of
tabs. Hence, we'd like to purge the tab_bar and tab_list labels from
our code base.
We purged tab_list in 1267caf5009118875f47fdafe312880af08024e1.
This commit purges tab_bar, it includes:
- A blanket search and replace of tab_bar with message_view_header.
- Splitting a single line comment in
tab_bar.js / message_view_header.js.
- The renaming of tab_bar.js to message_view_header.js.
- The renaming of tab_bar.hbs to message_view_header.hbs.
- A blanket search and replace of tab_data with
message_view_header_data.
- Replacing the single occurrence of tabbar with message_view_header
(it was within a comment.)
This is a pretty straightforward conversion.
The bulk of the diff is just changing emoji.js
to ES6 syntax.
There is one little todo that can be deferred
to the next commit--we are now set up to have
markdown.js require emoji.js directly, since
it is no longer on `window`.
Since we had extracted `image_upload_widget.hbs` HTML for
image upload widget's like user avatar, realm logo, realm icon
we can also extract `image_upload_widget.scss` SCSS file
from settings.scss file with all the CSS related
to image upload widget's.
This change will also help us to keep `settings.scss` cleaner.
This adds support for a "spoiler" syntax in Zulip's markdown, which
can be used to hide content that one doesn't want to be immediately
visible without a click.
We use our own spoiler block syntax inspired by Zulip's existing quote
and math block markdown extensions, rather than requiring a token on
every line, as is present in some other markdown spoiler
implementations.
Fixes#5802.

* Show an empty overlay of recent topics.
* Register click event to open recent topics.
* Launch recent topics on "t" keypress.
This is based on the draft overlay.
Previously, we handled this code only in message_list_view.js.
Now we support rendering stream descriptions and some dynamic
elements can be rendered in them, so we extract this new module
and use it in both the places.
Add methods to extract recent topics from received messages.
Process new messages as they are received.
Use new messages received from the server to extract recent_topics.
Node tests added.
`stream_topic_history` is a more appropriate name as this
module will contain information about last message of a
stream in upcoming commits. Function and variable names
are changed accordingly like:
* topic_history() -> per_stream_history()
* get_recent_names() -> get_recent_topic_names()
* name -> topic_name
The file populates `windows.i18n`, so now
the file name matches our convention.
Note that the module really just initializes
`i18next` and then does this:
window.i18n = i18next;
It doesn't really add any functionality to
third party library.
We now treat util like a leaf module and
use "require" to import it everywhere it's used.
An earlier version of this commit moved
util into our "shared" library, but we
decided to wait on that. Once we're ready
to do that, we should only need to do a
simple search/replace on various
require/zrequire statements plus a small
tweak to one of the custom linter checks.
It turns out we don't really need util.js
for our most immediate code-sharing goal,
which is to reuse our markdown code on
mobile. There's a little bit of cleanup
still remaining to break the dependency,
but it's minor.
The util module still calls the global
blueslip module in one place, but that
code is about to be removed in the next
few commits.
I am pretty confident that once we start
sharing things like the typeahead code
more aggressively, we'll start having
dependencies on util. The module is barely
more than 300 lines long, so we'll probably
just move the whole thing into shared
rather than break it apart. Also, we
can continue to nibble away at the
cruftier parts of the module.
webpack optimizes JSON modules using JSON.parse("{…}"), which is
faster than the normal JavaScript parser.
Update the backend to use emoji_codes.json too instead of the three
separate JSON files.

We now use vdom-ish techniques to track the
list items for the pm list. When we go to update
the list, we only re-render nodes whose data
has changed, with two exceptions:
- Obviously, the first time we do a full render.
- If the keys for the items have changed (i.e.
a new node has come in or the order has changed),
we just re-render the whole list.
If the keys are the same since the last re-render, we
only re-render individual items if their data has
changed.
Most of the new code is in these two modules:
- pm_list_dom.js
- vdom.js
We remove all of the code in pm_list.js that is
related to updating DOM with unread counts.
For presence updates, we are now *never*
re-rendering the whole list, since presence
updates only change individual line items and
don't affect the keys. Instead, we just update
any changed elements in place.
The main thing that makes this all work is the
`update` method in `vdom`, which is totally generic
and essentially does a few simple jobs:
- detect if keys are different
- just render the whole ul as needed
- for items that change, do the appropriate
jQuery to update the item in place
Note that this code seems to play nice with simplebar.
Also, this code continues to use templates to render
the individual list items.
FWIW this code isn't radically different than list_render,
but it's got some key differences:
- There are fewer bells and whistles in this code.
Some of the stuff that list_render does is overkill
for the PM list.
- This code detects data changes.
Note that the vdom scheme is agnostic about templates;
it simply requires the child nodes to provide a render
method. (This is similar to list_render, which is also
technically agnostic about rendering, but which also
does use templates in most cases.)
These fixes are somewhat related to #13605, but we
haven't gotten a solid repro on that issue, and
the scrolling issues there may be orthogonal to the
redraws. But having fewer moving parts here should
help, and we won't get the rug pulled out from under
us on every presence update.
There are two possible extensions to this that are
somewhat overlapping in nature, but can be done
one a time.
* We can do a deeper vdom approach here that
gets us away from templates, and just have
nodes write to an AST. I have this on another
branch, but it might be overkill.
* We can avoid some redraws by detecting where
keys are moving up and down. I'm not completely
sure we need it for the PM list.
If this gets merged, we may want to try similar
things for the stream list, which also does a fairly
complicated mixture of big-hammer re-renders and
surgical updates-in-place (with custom code).
BTW we have 100% line coverage for vdom.js.
This is mostly for tactical reasons. It's hard to
get 100% test coverage on topic_list.js, but it
should be easy to get 100% test coverage on this
very important function.
I considered just moving this code into topic_data.js,
but it just didn't feel quite right. I feel like
this is a pretty core piece of code that's nice
to be by itself and not be near other complicated
code that does stuff like build widgets or talk
to servers. (And, again, it's not just the actual
code here, which is pretty small, it's the unit
tests, which are inherently verbose to exercise
all the edge cases.)
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

We have ~5 years of proof that we'll probably never
extend Dict with more options.
Breaking the classes into makes both a little faster
(no options to check), and we remove some options
in FoldDict that are never used (from/from_array).
A possible next step is to fine-tune the Dict to use
Map internally.
Note that the TypeScript types for FoldDict are now
more specific (requiring string keys). Of course,
this isn't really enforced until we convert other
modules to TS.
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.

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.
