Instead of copying over a mostly-unchanged `postgresql.conf`, we
transition to deploying a `conf.d/zulip.conf` which contains the
only material changes we made to the file, which were previously
appended to the end.
While shipping separate while `postgresql.conf` files for each
supported version is useful if there is large variety in supported
options between versions, there is not no such variation at current,
and the burden of overriding the entire default configuration is that
it must be keep up to date wit the package's version.
pg_upgradecluster will start the cluster if the old cluster was
started before it ran, or if there are post-upgrade scripts to run.
Because neither of those are fully under our control, only attempt to
start the new cluster if it isn't already.
Installs which are upgrading to current `main`, and are upgrading for
the very first time from an install which was originally from git,
have a `/home/zulip/deployments/current` which, unlike all later
upgrades, is not a `git worktree` of `/srv/zulip.git`, but rather a
direct `git clone` of some arbitrary URL. As such, it does not have
an `upstream` remote, nor a cached `zulip-git-version` file.
This makes later attempts to determine the pre-upgrade revision of
git (for pre-deploy hooks) fail, as without a `zulip-git-version`
file, `ZULIP_VERSION` is insufficiently-specific (e.g. `6.1+git`), and
there is no guarantee the necessary tags exist either.
While we can make fresh git installs set up an `upstream` and run
`./tools/cache-zulip-git-version` going forward (see subsequent
commit), that does not address the issue for deploys which already
exist. For those, we must configure and fetch a `remote` in the old
checkout, followed by re-generating a cached `zulip-git-version`.
Fixes: #25076.
The existing `except subprocess.CalledProcessError` only catches if
there are syntax errors which prevent the `lastrun` file from being
written; it does not handle if there are properly-defined resources
which fail to evaluate (e.g. due to a missing dependency or file).
Check the `failed` resource count, and exit 2 if there are any such
resources. This will cause `zulip-puppet-apply --force --noop` (which
is used as a pre-flight check during upgrades) to properly detect and
signal on more types of invalid puppet configurations. In turn, this
will cause `upgrade-zulip` to not attempt to power through upgrades it
knows are destined to fail.
Since logrotate runs in a daily cron, this practically means "daily,
but only if it's larger than 500M." For large installs with large
traffic, this is effectively daily for 10 days; for small installs, it
is an unknown amount of time.
Switch to daily logfiles, defaulting to 14 days to match nginx; this
can be overridden using a zulip.conf setting. This makes it easier to
ensure that access logs are only kept for a bounded period of time.
Previously, we had an architecture where CSS inlining for emails was
done at provision time in inline_email_css.py. This was necessary
because the library we were using for this, Premailer, was extremely
slow, and doing the inlining for every outgoing email would have been
prohibitively expensive.
Now that we've migrated to a more modern library that inlines the
small amount of CSS we have into emails nearly instantly, we are able
to remove the complex architecture built to work around Premailer
being slow and just do the CSS inlining as the final step in sending
each individual email.
This has several significant benefits:
* Removes a fiddly provisioning step that made the edit/refresh cycle
for modifying email templates confusing; there's no longer a CSS
inlining step that, if you forget to do it, results in your testing a
stale variant of the email templates.
* Fixes internationalization problems related to translators working
with pre-CSS-inlined emails, and then Django trying to apply the
translators to the post-CSS-inlined version.
* Makes the send_custom_email pipeline simpler and easier to improve.

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%.

These hooks are run immediately around the critical section of the
upgrade. If the upgrade fails for preparatory reasons, the pre-deploy
hook may not be run; if it fails during the upgrade, the post-deploy
hook will not be run. Hooks are called from the CWD of the new
deploy, with arguments of the old version and the new version. If
they exit with non-0 exit code, the deploy aborts.

The `pg_upgrade` tool uses `pg_dump` as an internal step, and verifies

This was last really used in d7a3570c7e, in 2013, when it was
`/home/humbug/logs`.
Repoint the one obscure piece of tooling that writes there, and remove
the places that created it.
`check_version` in `install-yarn` had the rather careful check that
the yarn it installed into `/usr/bin/yarn` was the yarn which was
first in the user's `$PATH`. This caused problems when the user had a
pre-existing `/usr/local/bin/yarn`; however, those problems are
limited to the `install-yarn` script itself, since the nearly all
calls to yarn from Zulip's code already hardcode the `/srv/zulip-yarn`
location, and do not depend on what is in `$PATH`.
Remove the checks in `install-yarn` that depend on the local `$PATH`,
and stop installing our `yarn` into it. We also adjust the two
callsites which did not specify the full path to `yarn`, so use
`/srv/zulip-yarn`.

During installation on a new host, `create-database` attempts to
verify that there isn't a bunch of data already in the database which
is it about to drop and recreate. In the most common case, this
statement emits a scary-looking warning, since the database does not
exist yet:
```
+ /home/zulip/deployments/current/scripts/setup/create-database
+ POSTGRES_USER=postgres
++ crudini --get /etc/zulip/zulip.conf postgresql database_name
++ echo zulip
+ DATABASE_NAME=zulip
++ crudini --get /etc/zulip/zulip.conf postgresql database_user
++ echo zulip
+ DATABASE_USER=zulip
++ cd /
++ su postgres -c 'psql -v ON_ERROR_STOP=1 -Atc '\''SELECT COUNT(*) FROM zulip.zerver_message;'\'' zulip'
psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL: database "zulip" does not exist
```
Because we are attempting to gracefully handle the case where the
database does not exist yet, we also continue (and drop the database)
in other, less expected cases -- for instance, if database contains a
schema we do not expect.
Explicitly check for the database existence first, and once we verify
that, allow any further failures in the `SELECT COUNT(*)` to abort
`create-database`. This serves the dual purpose of hiding the "FATAL"
error for the common case when the database does not exist, as well as
preventing dropping the database if anything else goes awry.
If a previous attempt at an upgrade failed for some reason, the new
PostgreSQL may be installed, and the conversion will succeed, but the
new PostgreSQL daemon will not be running (Puppet does not force it to
start). This causes the upgrade to fail when analyzing statistics,
since the daemon isn't running.
Explicitly start the new PostgreSQL; this does nothing in most cases,
but will provider better resiliency when recovering from previous
partial upgrades.
Some terminals (e.g. ssh from OS X) set an invalid locale, which
causes the `pg_upgradecluster` call late in the upgrade to fail.
Force a known locale, for consistency. This mirrors the settings in
upgrade-zulip-stage-2, set in 11ab545f3b, and its subsequent
cleanups in 64c608a51a, ee0f4ca330, and eda9ce2364.
‘exit’ is pulled in for the interactive interpreter as a side effect
of the site module; this can be disabled with python -S and shouldn’t
be relied on.

If there is a syntax error in `settings.py`, `restart-server` should
provide a reasonable message about this. It did so prior to
af08bcdb3f, becausde any invocation `./manage.py` without
`--skip-checks` will verify `settings.py`, among several other checks.
After af08bcdb3f, there are no `./manage.py` calls in most restarts,
which fa77be6e6c took further.
Add an explicit `./manage.py check` in the default case.
upgrade-zulip-stage-2 overrides this by passing `--skip-checks`, for
performance. This also means that `upgrade-zulip-from-git` itself
picks up the same `--skip-checks` flag, since it inherits the same
flag parsing, though that is perhaps of dubious utility.
Although Node.js 18 is not the active LTS release for another 3 weeks,
the Node.js 16 end-of-life date was moved forward to September 2023,

prudent to switch now.

`postgresql-14.4` is a notable upgrade in the PostgreSQL series, as it
fixes potential database corruption from `CREATE INDEX CONCURRENTLY`
statements which are run while rows are modified[1]. However, it also
requires an upgrade from `libllvm9` to `libllvm10`, which means it is
not installed by a mere `apt-get upgrade`.
Add the `--with-new-pkgs` flag to all of the potentially relevant
`apt-get upgrade` calls, so that this (and similar) packages are
upgraded successfully.
