This was added by commit 7f174213ed, and
appears to have been designed for responses that are *successful* but
falsy. Logically, these should not implicitly represent a failure to
be retried if it were.
Note from tabbott: The background is that this idempotent retry loop
was a hacky workaround for a bug we never understood but saw daily in
production. Especially during server restarts / client reloads,
something would result in 200 responses with no data being seen by the
frontend, despite the Django server not having received/processed the
request. Fortunately, this strange failure mode appears to have
stopped happening in late 2019, so we can delete this hack.

ES and TypeScript modules are strict by default and don’t need this
directive. ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

Prettier would do this anyway, but it’s separated out for a more

We have changed our all instances of list_render to use
simplebar and thus, we will now use simplebar container
to track scroll event for all the lists created by
list_render.
This fixes the bug of new subscribers not rendering on
scrolling at the end of subscriber list in stream settings
and similar bug in some other lists also.
This commit also removes scroll_util.get_list_scrolling_container
function as this is no longer used.
Fixes#15637.
For some widgets we now avoid duplicate redraw
events from this old pattern:
widget = list_render.create(..., {
}).init();
widget.sort(...);
The above code was wasteful and possibly
flicker-y due to the fact that `init` and
`sort` both render.
Now we do this:
widget = list_render.create(..., {
init_sort: [...],
});
For other widgets we just clean up the need
to call `init()` right after `create()`.
We also allow widgets to pass in `sort_fields`
during initialization (since you may want to
have `init_sort` use a custom sort before the
first render.)
Finally, we make the second and third calls
eliminate the prior updates from the previous
widget. This can prevent strange bugs with
double-reversing columns (although that's
been prevented in a better way with a recent
commit), as well as avoiding double work
with sorting.
I pushed this risk commit to the end of
a PR that had a bunch of harmless prep
commits at the front, and I didn't make
it clear enough that the last commit (this
one) hadn't been tested thoroughly.
For the list_render widget, we can simplify
the intialization pretty easily (avoid
extra sorts, for example), but the cache aspects
are still tricky on subsequent calls.

Giving these functions a name and moving them to
the top-level scope has a couple tactical advantages:
- names show in tracebacks
- code is less indented
- setup code is less cluttered
- will be easier to add unit tests
- will make some upcoming diffs nicer
These are technically more `compare_foo` than `sort_foo`,
but we already had a naming convention that was sort of
in place.
The filter "callback" was only a "callback" in the
most general sense of the word.
It's just a filter predicate that returns a bool.
This is to prepare for another filtering option,
where the caller can filter the whole list
themselves. I haven't figured out what I will name
the new option yet, but I know I want to make the
two options have specific names.
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.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

With perfectScrollbar, we needed to call a function from JavaScript to
enable a scrollbar on a new element, but simplebar has a much simpler
default API one can do by using data-simplebar attributes in the HTML.
So we can delete all the scrollbar creation/deletion code.

In between releases, the following commit introduced
a bug where we agressively scroll to the top every
place we call `ui.update_scrollbar`:
092b73d0b7
The main symptoms were that the left and right sidebars
would go to the top for things like selecting a topic,
getting activity updates from the server, and resizing
the window. It was very jarring.
The recent commit looked innocuous--the root of the problem
was the original API expressed an intent to scroll to the
top, but didn't actually do it, so it was a bug in hiding.
There are **some** occasions where it's actually appropriate
to scroll to the top, mostly around search filtering, and
in those places we now call the new `ui.reset_scrollbar`
function.
This is a bit of an emergency fix, so particularly with
the settings stuff, we may get more reports of glitches here.
The important thing here is that you almost never want to
reset the scrollTop for sidebars.
Previously we only added the active class to the Date uploaded
column, thinking it was already sorted by upload date by default.
However, it wasn't, so now we explicitly make a call to sort it by upload
date to fix an issue with broken sorting.
Fixes#10518.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
We now do real-time sync to update the attachments UI when new
attachments are uploaded/deleted.
While we're at it, we fix the UI for the delete option to not do a
weird local echo thing.
This completes the work of a couple issues. There's still useful
performance work to do here (see the TODO), but it's a minor issue in
a rarely-used screen.
Fixes#6731.
Fixes#3710.
