Apparently, virtualenv-clone ends up copying the success-stamp file
that we use to track whether a virtualenv was successfully
provisioned, which results in problems if we get a network error in
the pip install stage afterwards.
The comment explains our fix, but basically we just delete
success-stamp after the clone.
Fixes#11301.
On usage errors (except --help), write usage message to stderr and
exit with nonzero status.
Forbid setting the hostname and email to the example values. Those
are specifically checked for and would fail later.

Instead, manually activate it in the one place where this
functionality was used (tools/lib/provision.py). This way we avoid
trying to activate the Python 2 thumbor virtualenv from Python 3.

Nowm unless you specify `--fill-cache`, memcached caches will not be
pre-filled after a server restart. This will be helpful when someone
is in a hurry (e.g. if the server is down right now, or if he/she
testing a configuration change in a newly setup server), it's best to
just restart without pre-filling the cache.
Fixes: #10900.
The site_packages variable points to (e.g.)
zulip-py3-venv/lib/python3.4/site-packages. If that doesn’t exist,
we’re probably running the wrong Python version.

We still create a Python 2 virtualenv for thumbor but that’s
separate (/srv/zulip-thumbor-venv from
scripts/lib/create-thumbor-venv).

Otherwise this causes an error
```
AttributeError: type object 'Callable' has no attribute '_abc_registry'
```
on 3.7. While the error is specific to 3.7, it is safer to uninstall
typing for all the versions that don't require a pip-provided typing
library.
/bin/sh and /usr/bin/env are the only two binaries that NixOS provides
at a fixed path (outside a buildFHSUserEnv sandbox).
This discussion was split from #11004.

This is a common bug that users might be tempated to introduce.
And also fix two instances of this bug that were present in our
codebase, including an important one in our upgrade code path.
This makes it possible to add --skip-purge-old-deployments in the
deploy_options section of /etc/zulip/zulip.conf, and control whether
old deployments are purged automatically on a system.
We still need to do https://github.com/zulip/zulip/issues/10534 and
probably also to add these arguments to be directly passed into
upgrade-zulip, but that can wait for future work.
Fixes#10946.
Since yarn has a package.json conveniently available, we can parse
that with jq, saving the expensive operation of starting up yarn.
This saves ~300ms in a no-op provision.
Apparently, we were incorrectly expressing the paths in the
caches_in_use data structures for these two cache-cleaning algorithms,
resulting in the default threshhold_days algorithm controlling which
caches could be garbage-collected. While the emoji one was just a
performance optimization for upgrade-zulip-from-git, it was possible
for the main `node_modules` cache in use in production to be GCed,
resulting in LaTeX rendering being broken.
