5308fbdeac split out `zulip::postgresql_client`, and 80ef38757a
made it no longer depend on `zulip::postgresql_common`, but directly
on `zulipconf('postgresql', 'version', undef)`. However, the
installer depended on recognizing `zulip::postgresql_common` in the
list of pulled-in classes to know that we needed to keep the
`postgresql.version` setting in `/etc/zulip.conf`.
Update the installer to also recognize `zulip::postgresql_client` as a
class which tells us to keep `postgresql.version` in our settings.
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.
This ensures that the next `upgrade-zulip-from-git` has access to the
commit history of the initial install, if it was from a forked
repository. `/home/zulip/deployments/current` and `/srv/zulip.git`
are not quite organized into the steady-state that they will have
after one `upgrade-zulip-from-git`:
- `/home/zulip/deployments/current` is its own clone, not a worktree
- `/srv/zulip.git` has an origin of `/home/zulip/deployments/current`
- `remote.origin.mirror` is set on `/srv/zulip.git`
- `remote.origin.fetch` is `+refs/*:refs/*`
All but the first are automatically cleaned up by
`upgrade-zulip-from-git` when it is next run, using the code added in
30457ecd02. The additional complexity of making an existing
independent clone into a worktree seem not worth solving the first
point.
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.
Corepack manages multiple per-project version of Yarn and PNPM, which
means we have to maintain less installation code, and could help us
switch away from Yarn 1 without making the system unusable for
development of other Yarn 1 projects.

`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.

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.
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.

This is required in order to lock down the RabbitMQ port to only
listen on localhost. If the nodename is `rabbit@hostname`, in most
circumstances the hostname will resolve to an external IP, which the
rabbitmq port will not be bound to.
Installs which used `rabbit@hostname`, due to RabbitMQ having been
installed before Zulip, would not have functioned if the host or
RabbitMQ service was restarted, as the localhost restrictions in the
RabbitMQ configuration would have made rabbitmqctl (and Zulip cron
jobs that call it) unable to find the rabbitmq server.
The previous commit ensures that configure-rabbitmq is re-run after
the nodename has changed. However, rabbitmq needs to be stopped
before `rabbitmq-env.conf` is changed; we use an `onlyif` on an `exec`
to print the warning about the node change, and let the subsequent
config change and notify of the service and configure-rabbitmq to
complete the re-configuration.
`/etc/rabbitmq/rabbitmq-env.conf` sets the nodename; anytime the
nodename changes, the backing database changes, and this requires
re-creating the rabbitmq users and permissions.
Trigger this in puppet by running configure-rabbitmq after the file
changes.
Installing certbot with --method=standalone means that the
configuration file will be written to assume that the standalone
method will be used going forward. Since nginx will be running,
attempts to renew the certificate will fail.
Install a temporary self-signed certificate, just to allow nginx to
start, and then follow up (after applying puppet to start nginx) with
the call to setup-certbot, which will use the webroot authenticator.
The `setup-certbot --method=standalone` option is left intact, for use
in development environments.
Fixes part of #20593; it does not address installs which were
previously improperly configured with `authenticator = standalone`.
As a consequence:
• Bump minimum supported Python version to 3.7.
• Move Vagrant environment to Debian 10, which has Python 3.7.
• Move CI frontend tests to Debian 10.
• Move production build test to Debian 10.

On a system where ‘apt-get update’ has never been run, ‘apt-cache

The certbot package installs its own systemd timer (and cron job,
which disabled itself if systemd is enabled) which updates
certificates. This process races with the cron job which Zulip
installs -- the only difference being that Zulip respects the
`certbot.auto_renew` setting, and that it passes the deploy hook.
This means that occasionally nginx would not be reloaded, when the
systemd timer caught the expiration first.
Remove the custom cron job and `certbot-maybe-renew` script, and
reconfigure certbot to always reload nginx after deploying, using
certbot directory hooks.
Since `certbot.auto_renew` can't have an effect, remove the setting.
In turn, this removes the need for `--no-zulip-conf` to
`setup-certbot`. `--deploy-hook` is similarly removed, as running
deploy hooks to restart nginx is now the default; pass
`--no-directory-hooks` in standalone mode to not attempt to reload
nginx. The other property of `--deploy-hook`, of skipping symlinking
into place, is given its own flog.
The support for bullseye was added in #17951
but it was not documented as bullseye was
frozen and did not have proper configuration
files, hence wasn't documented.
Since now bullseye is released as a stable
version, it's support can be documented.
The usual output from this command looks like
Notice: Compiled catalog for localhost in environment production in 2.33 seconds
Notice: /Stage[main]/Zulip::Apt_repository/Exec[setup_apt_repo]/returns: current_value 'notrun', should be ['0'] (noop)
Notice: Class[Zulip::Apt_repository]: Would have triggered 'refresh' from 1 event
Notice: Stage[main]: Would have triggered 'refresh' from 1 event
Notice: Applied catalog in 1.20 seconds
which doesn’t seem abnormally alarming, and hiding it makes failures
harder to diagnose.

set with the `--postgresql-database-name` and
`--postgresql-database-user` install script options. If these

The `en_US.UTF-8` locale may not be configured or generated on all
installs; it also requires that the `locales` package be installed.
If users generate the `en_US.UTF-8` locale without adding it to the
permanent set of system locales, the generated `en_US.UTF-8` stops
working when the `locales` package is updated.
Switch to using `C.UTF-8` in all cases, which is guaranteed to be
installed.
Fixes#15819.
In Debian, becoming root as `su` does not alter the `$PATH`; this can
lead to the root user not having `/usr/sbin` in its path, and thus
the `useradd zulip` step of the installer fails.
Fixes#17441.
For installs which use the `upgrade-zulip-from-git` process, the
deployment directory is a git checkout. This means that an
administrator can, as an emergency tool, run `git revert` and similar
commands -- assuming there is a `~/.gitconfig` set up for the zulip
user.
Add commands to `scripts/lib/install` to create a `~/.gitconfig` file
at installation time. The `user.name` and `user.email` fields are set
to the hostname and passed-in `--email` value, respectively.
Fixes#18039.
