When we redraw the left sidebar, we need to tell the
topic list to clear its data structures (and do other
stuff like hiding its popover), since we are clearing
its parent container.
The commit f0e18b3b3e
introduced this regression in late January 2020.
That commit made topic_list use a vdom to avoid
unnecessary updates. Before that, topic_list did
a lot of brute-force redraws, which covered up the
fact that we weren't having stream_list telling it
when the rug was being pulled out from under it.
The boundary between stream_list and topic_list
has always been kind of complicated code, since
topic lists get embedded into the stream list.
The main interactions, though, are basically:
* topic_zoom.clear_topics() - you're leaving
a narrow that may or may not be zoomed
* topic_list.clear() - you're about to redraw
stream items in the unzoomed stream list
* topic_list.rebuild(stream_li, stream_id) -
you're building or updating a topic list
for the newly active stream

Explicitly stubbing i18n in 48 different files
is mostly busy work at this point, and it doesn't
provide much signal, since often it's invoked
only to satisfy transitive dependencies.
This is not always a behavior-preserving translation: _.extend mutates
its first argument. However, the code does not always appear to have
been written to expect that.

This moves some code from settings_display.js
into the new module settings_config.js.
Extracting this module breaks some dependencies
on settings_display.js (which has some annoying
transitive dependencies, including jQuery).
In particular this isolates stream_data from
from settings_display.js.
Two of the three structures that we moved here
weren't even directly used by settings_display.js,
since we do a lot of rendering in the modules
admin.js and setting.js.
We make get_all_display_settings() a function
to avoid a require-time dependency on page_params.
Breaking the dependencies simplifies a few
node tests.
Most of the node test complexity came from the
following commit in March 2019:
5a130097bf
The commit itself seems harmless enough, but
dependencies can have a somewhat "viral" nature,
where making stream_data depend on settings_display
caused us to modify four different node tests.
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.
We just get the stream_name from the sub struct now.
This mostly affects node tests.
The only place in real code where we called add_sub()
was when we initialized data from the server.
We avoid complicated code to update unread counts
by just using vdom.js.
One small change here is that if click on "more
topics", we replace it with the spinner instead
of putting the spinner after it. This saves us
a redraw under the new scheme.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.
It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.
This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.
With many tweaks by tabbott to documentation under /help, etc.

stream_count and topic_count in the actual code have been IntDict
since commit 9ba1829243 (#13569).

This is relatively unobtrusive, and we don't send
anything to the server.
But any user can now enter blueslip.timings in the
console to see a map of how long things take in
milliseconds. We only record one timing per
event label (i.e. the most recent).
It's pretty easy to test this by just clicking
around. For 300 users/streams most things are
fast except for:
- initialize_everything
- manage streams (render_subscriptions)
Both do lots of nontrivial work, although
"manage streams" is a bit surprising, since
we're only measuring how long to build the
HTML from the templates (whereas the real
time is probably browser rendering costs).
We now require the actual tests to explicitly
to zrequire Dict, rather than magically adding this.
In one case, the use of Dict was clearly just for
the test (not the app), so I converted that an ordinary
JS object (see timerender.js).
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 commit was originally automatically generated using `tools/lint
--only=eslint --fix`. It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

Although SimpleBar automatically sets itself up on elements with a
`data-simplebar` attribute, sometimes we try to set event listeners
before that happens. Create the SimpleBar early in that case.

This adds a setting to control Zulip's default behavior of sorting to
bottom and graying out inactive streams. The previous logic is still
the default "automatic", but this gives users more control. See the
models.py comment for details.
Fixes#11524.
We have had a longtime bug where the state of pinned streams would not
update properly from the greyed out/inactive state to the active state
when a first message arrived to them.
After some discussion, we determined that likely the right fix for
this is to simply configure pinned streams to never be marked as
inactive; that's more in line with the intended user experience.
Fixes#8201.
We now use a Proxy to wrap zjquery elements, so
that we can detect callers trying to invoke methods
(or access attributes) that do not exist. We try
to give useful error messages in those cases.
The main impact here is that we force lots of tests
to explicitly stub `length`.
Also, we can't do equality checks on zjquery
objects any more due to the proxy object, but the
easy workaround is to compare selectors. (This
is generally an unnecessary technique, anyway.)
The proxy wrapper is fairly straightforward, and
we just have a few special cases for things like
"inspect" that happen when you try to print out
objects.
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.

The stream_list test that was fixed here was sort of
broken. It accomplished the main goal of verifying
what gets rendered, but now the data setup part is
more like the actual app code (and simpler, too).
If you zoom into "more topics" for a stream that has
a LOT of topics, and then scroll down to the bottom,
and then zoom out by selecting "All messages" or
similar upper-left-sidebar options, we now try to scroll
the more recently active stream back into place after we scroll
out.
Before this change, it was possible for your lower left
sidebar to appear empty, as it would keep the
scroll offset from "more topics".
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 allows several modules to no longer need
to import `narrow` (or, in our current pre-import
world, to not have to use that global).
The broken dependencies are reflected in the node
tests, which should now run slightly faster.
We now initialize most modules in ui_init.js, which
isn't the perfect place to do it, but at least now
we have a mostly consolidated entry point.
All the new foo.initialize() methods introduced in
this module run the same order relative to each
other as before this commit. (I did some console
logging with a hacked version of the program to
get the order right.) They happen a bit later than
before, though.
A couple modules still have the `$(function() {`
idiom for miscellaneous reasons:
archive - is a different bundle
common - used elsewhere
list_render - non-standard code style
scroll_bar - no exports
setup - probably special?
socket - $(function () is nested!
transmit - coupled to socket
translations - i18n is a bigger problem
ui_init - this bootstraps everything
This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests. (The latter goal has some
complications, since we often intentionally leak
setup in tests.)
The new list_cursor class is more generic and saves the state
of your cursor across redraws.
Note that we no longer cycle from bottom to top or vice versa.
The node test code that was removed here was kind of complex
and didn't actually assert useful things after calling methods.
This commit prefixes stream names in urls with stream ids,
so that the urls don't break when we rename streams.
strean name: foo bar.com%
before: #narrow/stream/foo.20bar.2Ecom.25
after: #narrow/stream/20-foo-bar.2Ecom.25
For new realms, everything is simple under the new scheme, since
we just parse out the stream id every time to figure out where
to narrow.
For old realms, any old URLs will still work under the new scheme,
assuming the stream hasn't been renamed (and of course old urls
wouldn't have survived stream renaming in the first place). The one
exception is the hopefully rare case of a stream name starting with
something like "99-" and colliding with another stream whose id is 99.
The way that we enocde the stream name portion of the URL is kind
of unimportant now, since we really only look at the stream id, but
we still want a safe encoding of the name that is mostly human
readable, so we now convert spaces to dashes in the stream name. Also,
we try to ensure more code on both sides (frontend and backend) calls
common functions to do the encoding.
Fixes#4713
When in the stream-searchbar, a user can now use the arrow keys to iterate
through the suggestions. Therefore the currently selected list element is
assigned a CSS class 'highlighted_user'.
The main functional testing is done with casper but node test are still
included to keep the high coverage.
Line-wrapping issues are resolved. Night-mode CSS handling is included.
Here are the functions in top_left_corner:
get_global_filter_li: pure code move
update_count_in_dom: simplifed copy of similar function in stream_list.js
update_dom_with_unread_counts: pure code move, split out from function
of same name in stream_list.js
delselect_top_left_corner_items: pure code move
handle_narrow_activated: pure code move + rename
handle_narrow_deactivated: pure code move, split out from from function
of smae name in stream_list.js
This fix simplifies how we re-render topic lists when we
re-narrow or zoom out from a topic list.
* The topic_list.zoom_out() no longer gets called as
part of re-narrowing, and we eliminate the clear_topics
option.
* For all situations where we narrow to a filter that does
not have a topic, we simply call the new function
clear_topics().
* The stream_list code no longer calls remove_expanded_topics()
in cases where the new narrow has a topic. This allows us
to optimize away scroll/flicker churn a little more easily.
As part of this, we rename maybe_activate_stream_item() to
update_stream_sidebar_for_narrow(), since the function clears
stuff as well as turning stuff on.
We have code that can automatically scroll an element into "view"
in its container. We use this for stream sidebar rows inside the
stream list.
Generally the stream sidebar rows are small enough to fit into
the container, and the prior algorithm worked correctly for that
scenario.
If you have lots of topics, however, and a short screen, the
algorithm was being too aggressive. For example, if the top
wasn't showing, it would scroll the top into view, but at the
cost of scrolling the bottom out of view.
This fix makes the general scrolling algorithm more tame.
Part of the user-facing problem is that the element we pass
into the scrolling code for the stream sidebar rows is bigger
than the part of the row that actually should be shown on
screen. Nevertheless, it makes sense here to make the general
algorithm more robust.
