certbot-auto doesn’t work on Ubuntu 20.04, and won’t be updated; we
migrate to instead using the certbot package shipped with the OS
instead. Also made sure that sure certbot gets installed when running
zulip-puppet-apply, to handle existing systems.
We're migrating to using the cleaner zulip.com domain, which involves
changing all of our links from ReadTheDocs and other places to point
to the cleaner URL.
datetime.timezone is available in Python ≥ 3.2. This also lets us
remove a pytz dependency from the PostgreSQL scripts.

This is vestigial.
It requires manually altering the `htdigest` file (not stored in this
repo) to change the digest realm from `wiki` to `monitoring`, and will
re-prompt users for their passwords if the browsers currently store
them.
Drop the change to move `/tmp` onto the local disk. Doing this move
confuses `resolved` until there is a restart, and has no clear
benefits. The change came in during bf82fadc95, but does not describe
the reasoning; it is particularly puzzling, since postgresql stores
its temporary files under `$PGDATA/base/pgsql_tmp`.
Do not RAID the disks together. This was previously done when they
were spinning media, for reliability; running them on an SSD obviates
this sufficiently. This means that updating the initramfs is also not
necessary.
This no longer has any rules specific to it. We leave the `postgres`
munin group (which now only contains `postgres_appdb`) as
future-proofing, and so that `postgres_appdb` matches to the puppet
manifest of the same name.
This allows straight-forward configuration of realm-based Tornado
sharding through simply editing /etc/zulip/zulip.conf to configure
shards and running scripts/refresh-sharding-and-restart.

memcached 1.5.22 in Ubuntu 20.04 has a bug where it looks for its SASL
configuration at /etc/sasl2/memcached.conf/memcached.conf instead of
/etc/sasl2/memcached.conf.

Using the `host` virtual package confused Puppet into reporting it was
doing work every time one did a puppet run, resulting in unnecessarily
spammy output.
While this functionality to post slow queries to a Zulip stream was
very useful in the early days of Zulip, when there were only a few
hundred accounts, it's long since been useless since (1) the total
request volume on larger Zulip servers run by Zulip developers, and
(2) other server operators don't want real-time notifications of slow
backend queries. The right structure for this is just a log file.
We get rid of the queue and replace it with a "zulip.slow_queries"
logger, which will still log to /var/log/zulip/slow_queries.log for
ease of access to this information and propagate to the other logging
handlers. Reducing the amount of queues is good for lowering zulip's
memory footprint and restart performance, since we run at least one
dedicated queue worker process for each one in most configurations.
Our priority hierarchy is:
(1) Tornado and base services like memcached, redis, etc.
(2) Django and message sender queue workers.
(3) Everything else.
Ideally, we'd have something a bit more fine-grained (e.g. some queue
workers are potentially in the sending path, while others aren't), but
this should have a big impact on ensuring Tornado gets the resources
it needs during load spikes.
I think this has a good chance of causing some load spikes that would
previously have resulted in a user-facing delivery delays no longer
having any significant user-facing impact.
Currently when the user uploads files with ".jpe" file extension, the
markdown is converted to link but the image is not embedded.
This commit adds the support for ".jpe" file extension.

We could anchor the regexes, but there’s no need for the power (and
responsibility) of regexes here.

This PR updates the puppet manifest to allow /etc/zulip to be a symlink. The current behaviour overwrites /etc/zulip if it is link to another directory, which is problematic with docker-zulip and
in particular the `LINK_SETTINGS_TO_DATA` setting.
