Replace a separate call to subprocess, starting `node` from scratch,
with an optional standalone node Express service which performs the
rendering. In benchmarking, this reduces the overhead of a KaTeX call
from 120ms to 2.8ms. This is notable because enough calls to KaTeX in
a single message would previously time out the whole message
rendering.
The service is optional because he majority of deployments do not use
enough LaTeX to merit the additional memory usage (60Mb).
Fixes: #17425.
Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.

On a 2 GiB, 1 CPU system, webpack would hit the Node.js heap
limit (which is half of physical memory up to 4 GiB, on 64-bit
systems).

These changes are all independent of each other; I just didn’t feel
like making dozens of commits for them.

We lost the war against top level configuration files many moons ago.
This is what developers and tools expect. And it seems to be required
for eslint-import-resolver-webpack (there’s ostensibly a {"config":
"tools/webpack.config.ts"} option, but it doesn’t work correctly:
https://github.com/benmosher/eslint-plugin-import/issues/1861).

There are file sharing issues with the macOS 10.15.6 and
vagrant. var/remote_cache_prefix was an empty file when using
VirtualBox and Docker on macOS.
Using parallels as a provider for vagrant fixes the issue.
Use --watch-poll which makes webpack to recompile
automatically on file changes, since inotify is not
working here too.
Fixes#2665.
Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

Polling for changes every 100 milliseconds was burning enough CPU to
set mid-2015 MacBooks on fire. Use the default inotify watching,
except on filesystems where that’s known not to work (nfs, vboxsf), in
which case polling once per second is more than enough for even the
fastest typers.

This gives us access to typing_extensions.Deque, which was not added
to typing until 3.5.4.
(PROVISION_VERSION is not bumped because the transitive dependency set
in dev.txt hasn’t changed.)

This exchanges a race condition where webpack-dev-server might not be
stopped on a poorly timed KeyboardInterrupt for a less bad race
condition where we might get an UnboundLocalError.

This should make the run-dev.py user experience a lot nicer when
switching branches away from a branch that is at least as new as this
commit, since we won't need to manually restart run-dev.py to restart
webpack.
Fixes#9042.
`tools/run-dev.py` already backgrounds `tools/webpack` (and deals with
cleaning it up on exit), so there’s no need for `tools/webpack` to
also background the actual `webpack` process. But when running
`tools/webpack` by itself, it’s annoying to clean up the backgrounded
process manually.
Run `webpack` in the foreground, using `os.execvp` so we don’t waste
memory on an intermediate wrapper process.
