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.
We previously used `zulip-puppet-apply` with a custom config file,
with an updated PostgreSQL version but more limited set of
`puppet_classes`, to pre-create the basic settings for the new cluster
before running `pg_upgradecluster`.
Unfortunately, the supervisor config uses `purge => true` to remove
all SUPERVISOR configuration files that are not included in the puppet
configuration; this leads to it removing all other supervisor
processes during the upgrade, only to add them back and start them
during the second `zulip-puppet-apply`.
It also leads to `process-fts-updates` not being started after the
upgrade completes; this is the one supervisor config file which was
not removed and re-added, and thus the one that is not re-started due
to having been re-added. This was not detected in CI because CI added
a `start-server` command which was not in the upgrade documentation.
Set a custom facter fact that prevents the `purge` behaviour of the
supervisor configuration. We want to preserve that behaviour in
general, and using `zulip-puppet-apply` continues to be the best way
to pre-set-up the PostgreSQL configuration -- but we wish to avoid
that behaviour when we know we are applying a subset of the puppet
classes.
Since supervisor configs are no longer removed and re-added, this
requires an explicit start-server step in the instructions after the
upgrades complete. This brings the documentation into alignment with
what CI is testing.
Recommonmark is no longer maintained, and MyST-Parser is much more
complete.

The auth attempt rate limit is quite low (on purpose), so this can be a
common scenario where a user asks their admin to reset the limit instead
of waiting. We should provide a tool for administrators to handle such
requests without fiddling around with code in manage.py shell.
These checks suffer from a couple notable problems:
- They are only enabled on staging hosts -- where they should never
be run. Since ef6d0ec5ca, these supervisor processes are only
run on one host, and never on the staging host.
- They run as the `nagios` user, which does not have appropriate
permissions, and thus the checks always fail. Specifically,
`nagios` does not have permissions to run `supervisorctl`, since
the socket is owned by the `zulip` user, and mode 0700; and the
`nagios` user does not have permission to access Zulip secrets to
run `./manage.py print_email_delivery_backlog`.
Rather than rewrite these checks to run on a cron as zulip, and check
those file contents as the nagios user, drop these checks -- they can
be rewritten at a later point, or replaced with Prometheus alerting,
and currently serve only to cause always-failing Nagios checks, which
normalizes alert failures.
Leave the files installed if they currently exist, rather than
cluttering puppet with `ensure => absent`; they do no harm if they are
left installed.
Strictly speaking, this sentence is talking about the IdP configuration,
while the backend is just GenericOpenIdConnectBackend, so the new
phrasing is more correct.
The script is added to upgrade steps for 20.04 and Buster because
those are the upgrades that cross glibc 2.28, which is most
problematic. It will also be called out in the upgrade notes, to
catch those that have already done that upgrade.
Fixes#17277.
The main limitation of this implementation is that the sync happens if
the user authing already exists. This means that a new user going
through the sign up flow will not have their custom fields synced upon
finishing it. The fields will get synced on their consecutive log in via
SAML in the future. This can be addressed in the future by moving the
syncing code further down the codepaths to login_or_register_remote_user
and plumbing the data through to the user creation process.
We detail that limitation in the documentation.
Updated the install documentation to include the explanation of the
two new install options `--postgresql-database-name` and
`--postgresql-database-user`.
