The "invites" worker exists to do two things -- make a Confirmation
object, and send the outgoing email. Making the Confirmation object
in a background process from where the PreregistrationUser is created
temporarily leaves the PreregistrationUser in invalid state, and
results in 500's, and the user not immediately seeing the sent
invitation. That the "invites" worker also wants to create the
Confirmation object means that "resending" an invite invalidates the
URL in the previous email, which can be confusing to the user.
Moving the Confirmation creation to the same transaction solves both
of these issues, and leaves the "invites" worker with nothing to do
but send the email; as such, we remove it entirely, and use the
existing "email_senders" worker to send the invites. The volume of
invites is small enough that this will not affect other uses of that
worker.

Testing for it in Python means that we have to worry about keeping the
`upgrade-zulip-stage-2` backwards-compatible with all versions of
Python which we could ever be upgrading from -- which is all of them.
Factor out the "supported operating systems" check, and share it
between upgrade and install codepaths.
`--no-init-db` is used to silence the need for `--hostname` and
`--email` arguments; it is a proxy for "this is not a frontend host."
We would ideally like to use `has_class` to know if the user's
provided puppet classes are include an `app_frontend`, and thus
`--hostname` and `--email` are required -- but doing that requires
several other steps, and we would like this feedback to be immediate.
We make the presence of `--puppet-classes` equivalent to
`--no-init-db`, since nearly every configuration with
`--puppet-classes` does not install both a database and a frontend,
which is what is required to initialize a database.
If running on a stand-alone PostgreSQL server, then supervisor does
exist -- but `stop-server` is useless, and in fact cannot run because
the Zulip directory may not be readable by the `zulip` user.
Detect if this is an application front-end server by looking for
`/home/zulip/deployments`, and use the stop-server and flush-memcached
from there if it exists. The `create-db.sql` and
`terminate-psql-sessions` files are still read from the local
directory, but those already have precautions from being from a
non-world-readable directory, and are more obviously important to keep
in sync with the `create-database` script.
This package is replaced by libmagic1t64 1:5.45-3 for the Ubuntu
64-bit time_t transition, but hasn’t been deleted from the archive
yet.

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.
While this could be done previously by calling
`upgrade-zulip-from-git --remote-url /srv/zulip.git`, the explicit
argument makes this more straightforward, and avoids churning the
`refs/remotes/origin/` namespace.
A user who somehow got an empty `zulip` database, but without a
`zerver_messages` table in it, would get stuck in the installer at:
```
++ su postgres -c 'cd / && psql -v ON_ERROR_STOP=1 -Atc '\''SELECT COUNT(*) FROM zulip.zerver_message;'\'' zulip'
ERROR: relation "zulip.zerver_message" does not exist
LINE 1: SELECT COUNT(*) FROM zulip.zerver_message;
^
+ records=
```
Treat a failure to select from `zerver_messages` as having 0 messages,
and continue with the `DROP DATABASE IF EXISTS` / `CREATE DATABASE`
that `create-db.sql` usually does.
Fixes: #29110.
This leaves `args.filter_terms` as the raw values the user specified,
before they may have been transformed to the shape that we use for
substring matching.
