These have more accurate timestamps, and have user information --
but are harder to parse, and will not show requests when Django or
Tornado is stopped.
This is a script to search nginx log files by server hostname or
client IP address, and output matching lines, all while skipping
common and less-interesting request lines.
As a consequence:
• Bump minimum supported Python version to 3.8.
• Move Vagrant environment to Ubuntu 20.04, which has Python 3.8.
• Move CI frontend tests to Ubuntu 20.04.
• Move production build test to Ubuntu 20.04.
• Move 3.4 upgrade test to Ubuntu 20.04.

We previously used restart-server if puppet was run, as a nod to the
fact that `supervisor reread && supervisor update` will _start_
service groups that were modified, even if they were previously
stopped; this is because they are marked as `autostart=true`, which is
honored on service change.
However, upgrades want to run while there are no services running. If
puppet is run, explicitly set the server as potentially being "up", so
that a `shutdown_server()` before migrations, if they exist, will stop
services.
7c4293a7d3 switched to checking if the
service was already running, and use `supervisorctl start` if it was
not.
Unfortunately, `list_supervisor_processes("zulip-tornado:*")` did not
include `zulip-tornado`, and as such a non-sharded process was always
considered to _not_ be running, and was thus started, not restarted.
Starting an already-started service is a no-op, and thus non-sharded
tornado processes were never restarted.
The observed behaviour is that requests to the tornado process attempt
to load the user from the cache, with a different prefix from Django,
and immediately invalidate the session and eject the user back to the
login page.
Fix the `list_supervisor_processes` logic to match without the
trailing `:*`.
We had skipped these in #14693 so we could keep generating a friendly
error on Python 3.5, but we gave that up in #19801.

Since wal-g does not provide binaries for aarch64, build them from
source. While building them from source for arm64 would better ensure
that build process is tested, the build process takes 7min and 700M of
temp files, which is an unacceptable cost; we thus only build on
aarch64.
Since the wal-g build process uses submodules, which are not in the
Github export, we clone the full wal-g repository. Because the
repository is relatively small, we clone it anew on each new version,
rather than attempt to manage the remotes.
Fixes#21070.
stop-server and restart-server address all services which talk to the
database, and are thus more correct than restarting or stopping
everything in supervisor.
This is possible now that the previous commit ensures that the zulip
user can read the zulip installation directory during
`create-database`; previously, that directory was still owned by root
when `create-database` was run, whereas now it is in
`~zulip/deployments/`.
Move database creation to immediately before database initialization;
this means it happens in a directory readable by the `zulip` user, as
well as placing it alongside similar operations. It removes the check
for the `zulip::postgresql_common` Puppet class; instead it keeps the
check for `--no-init-db`, and switches to require
`zulip::app_frontend_base`. This is a behavior change for any install
of `zulip::postgresql_common`-only classes, but that is not a common
form -- and such installs likely already pass `--no-init-db` because
they are warm spare replicas.
As a result, all non-`zulip::app_frontend_base` installs now skip
database initialization, even without `--no-init-db`. This is clearly
correct for, e.g. Redis-only hosts, and makes clearer that the
frontend, not the database host, is responsible for database
initialization.
rabbitmqctl ping only checks that the Erlang process is registered
with epmd. There’s a window after that where the rabbit app is still
starting inside it.

This was added in c770bdaa3a, and we
have not added any realm-internal bots since
c770bdaa3a.
Speed up the critical period during upgrades by skipping this step.
Using an absolute `ZULIP_SCRIPTS` path when computing sha245sums
results in a set of hashes which varies based on the path that the
script is called as. This means that each deploy _always_ has
`setup-apt-repo --verify` fail, since it is a different base path.
Make all paths passed to sha256sum be relative to the repository root,
ensuring they can be compared across runs.
In some instances (e.g. during upgrades) we run `restart-server` and
not `start-server`, even though we expect the server to most likely
already be stopped. `supervisorctl restart servicename` if the
service is stopped produces the perhaps-alarming message:
```
restart-server: Restarting servicename
servicename: ERROR (not running)
servicename: started
```
This may cause operators to worry that something is broken, when it is
not.
Check if the service is already running, and switch from "restart" to
"start" in cases where it is not.
The race condition here is safe -- if the service transitions from
stopped to started between the check and the `start` call, it will
merely output:
```
servicename: ERROR (already started)
```
...and continue, as that has exit status 0.
If the service transitions from started to stopped between the check
and the `restart` call, we are merely back in the current case, where
it outputs:
```
servicename: ERROR (not running)
servicename: started
```
In none of these cases does a call to "restart" fail to result in the
service being stopped and then started.
Ubuntu 22.04 pushed a post-feature-freeze update to Python 3.10,
breaking virtual environments in a Debian patch
(https://bugs.launchpad.net/ubuntu/+source/python3.10/+bug/1962791).
Also, our antique version of Tornado doesn’t work in 3.10, and we’ll
need to do some work to upgrade that.

We can safely ignore the presence of the extra tables that could be
left behind in the database from when we had these installed (before
Zulip 1.7.0 and 2.0.0, respectively).

This was not needed for OpenSSL ≥ 1.1.1 (all our supported platforms),
and breaks with OpenSSL ≥ 3.0.0 (Ubuntu 22.04). It was removed from
the upstream configuration file too: https://bugs.debian.org/990228.
