Previously, it was possible to configure `wal-g` backups without
replication enabled; this resulted in only daily backups, not
streaming backups. It was also possible to enable replication without
configuring the `wal-g` backups bucket; this simply failed to work.
Make `wal-g` backups always streaming, and warn loudly if replication
is enabled but `wal-g` is not configured.

It seems like orange is the loudest possible color to
denote a quasi-neutral-idle state, so we hope to
replace it with another color.
This commit does not change any styling.
I removed the sentences in the doc, since they are
kind of too vague to be useful. If we want to say that
the idle state is correlated with the half-orange
circles in the buddy list, then we want to say that
more specifically.
The node test was slightly inaccurate.
I added `# etc.` to try to make it clear that
these are just examples.
I removed the puppeteer example, so that we
don't lie about "run in just a few seconds".
Renames `/docs/documentation/user.md` to reflect the rebranding
from "user documentation" to "help center documentation".
Also, fixes any linking in the docs to that file.
Updates the tutorial for writing help center articles to encourage
contributors to add to or enhance the existing help center docs
before writing a new articles for new features.
Also, generally updates references to 'user documentation' to be
'help center documentation'.
Additionally, updates some headers within the tutorials for clarity
and consistency, and adds some linkifying throughout the section on
writing documentation.
The RabbitMQ docs state ([1]):
RabbitMQ nodes and CLI tools (e.g. rabbitmqctl) use a cookie to
determine whether they are allowed to communicate with each
other. [...] The cookie is just a string of alphanumeric
characters up to 255 characters in size. It is usually stored in a
local file.
...and goes on to state (emphasis ours):
If the file does not exist, Erlang VM will try to create one with
a randomly generated value when the RabbitMQ server starts
up. Using such generated cookie files are **appropriate in
development environments only.**
The auto-generated cookie does not use cryptographic sources of
randomness, and generates 20 characters of `[A-Z]`. Because of a
semi-predictable seed, the entropy of this password is thus less than
the idealized 26^20 = 94 bits of entropy; in actuality, it is 36 bits
of entropy, or potentially as low as 20 if the performance of the
server is known.
These sizes are well within the scope of remote brute-force attacks.
On provision, install, and upgrade, replace the default insecure
20-character Erlang cookie with a cryptographically secure
255-character string (the max length allowed).
[1] https://www.rabbitmq.com/clustering.html#erlang-cookie
Zulip writes a `rabbitmq.config` configuration file which locks down
RabbitMQ to listen only on localhost:5672, as well as the RabbitMQ
distribution port, on localhost:25672.
The "distribution port" is part of Erlang's clustering configuration;
while it is documented that the protocol is fundamentally
insecure ([1], [2]) and can result in remote arbitrary execution of
code, by default the RabbitMQ configuration on Debian and Ubuntu
leaves it publicly accessible, with weak credentials.
The configuration file that Zulip writes, while effective, is only
written _after_ the package has been installed and the service
started, which leaves the port exposed until RabbitMQ or system
restart.
Ensure that rabbitmq's `/etc/rabbitmq/rabbitmq.config` is written
before rabbitmq is installed or starts, and that changes to that file
trigger a restart of the service, such that the ports are only ever
bound to localhost. This does not mitigate existing installs, since
it does not force a rabbitmq restart.
[1] https://www.erlang.org/doc/apps/erts/erl_dist_protocol.html
[2] https://www.erlang.org/doc/reference_manual/distributed.html#distributed-erlang-system
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.
The Erlang `epmd` daemon listens on port 4369, and provides
information (without authentication) about which Erlang processes are
listening on what ports. This information is not itself a
vulnerability, but may provide information for remote attackers about
what local Erlang services (such as `rabbitmq-server`) are running,
and where.
`epmd` supports an `ERL_EPMD_ADDRESS` environment variable to limit
which interfaces it binds on. While this environment variable is set
in `/etc/default/rabbitmq-server`, Zulip unfortunately attempts to
start `epmd` using an explicit `exec` block, which ignores those
settings.
Regardless, this lack of `ERL_EPMD_ADDRESS` variable only controls
`epmd`'s startup upon first installation. Upon reboot, there are two
ways in which `epmd` might be started, neither of which respect
`ERL_EPMD_ADDRESS`:
- On Focal, an `epmd` service exists and is activated, which uses
systemd's configuration to choose which interfaces to bind on, and
thus `ERL_EPMD_ADDRESS` is irrelevant.
- On Bionic (and Focal, due to a broken dependency from
`rabbitmq-server` to `epmd@` instead of `epmd`, which may lead to
the explicit `epmd` service losing a race), `epmd` is started by
`rabbitmq-server` when it does not detect a running instance.
Unfortunately, only `/etc/init.d/rabbitmq-server` would respects
`/etc/default/rabbitmq-server` -- and it defers the actual startup
to using systemd, which does not pass the environment variable
down. Thus, `ERL_EPMD_ADDRESS` is also irrelevant here.
We unfortunately cannot limit `epmd` to only listening on localhost,
due to a number of overlapping bugs and limitations:
- Manually starting `epmd` with `-address 127.0.0.1` silently fails
to start on hosts with IPv6 disabled, due to an Erlang bug ([1],
[2]).
- The dependencies of the systemd `rabbitmq-server` service can be
fixed to include the `epmd` service, and systemd can be made to
bind to `127.0.0.1:4369` and pass that socket to `epmd`, bypassing
the above bug. However, the startup of this service is not
guaranteed, because it races with other sources of `epmd` (see
below).
- Any process that runs `rabbitmqctl` results in `epmd` being started
if one is not currently running; these instances do not respect any
environment variables as to which addresses to bind on. This is
also triggered by `service rabbitmq-server status`, as well as
various Zulip cron jobs which inspect the rabbitmq queues. As
such, it is difficult-to-impossible to ensure that some other
`epmd` process will not win the race and open the port on all
interfaces.
Since the only known exposure from leaving port 4369 open is
information that rabbitmq is running on the host, and the complexity
of adjusting this to only bind on localhost is high, we remove the
setting which does not address the problem, and document that the port
is left open, and should be protected via system-level or
network-level firewalls.

Because Camo includes logic to deny access to private subnets, routing
its requests through Smokescreen is generally not necessary. However,
it may be necessary if Zulip has configured a non-Smokescreen exit
proxy.
Default Camo to using the proxy only if it is not Smokescreen, with a
new `proxy.enable_for_camo` setting to override this behaviour if need
be. Note that that setting is in `zulip.conf` on the host with Camo
installed -- not the Zulip frontend host, if they are different.
Fixes: #20550.
For `no_serve_uploads`, `http_only`, which previously specified
"non-empty" to enable, this tightens what values are true. For
`pgroonga` and `queue_workers_multiprocess`, this broadens the
possible values from `enabled`, and `true` respectively.
Restarting the uwsgi processes by way of supervisor opens a window
during which nginx 502's all responses. uwsgi has a configuration
called "chain reloading" which allows for rolling restart of the uwsgi
processes, such that only one process at once in unavailable; see
uwsgi documentation ([1]).
The tradeoff is that this requires that the uwsgi processes load the
libraries after forking, rather than before ("lazy apps"); in theory
this can lead to larger memory footprints, since they are not shared.
In practice, as Django defers much of the loading, this is not as much
of an issue. In a very basic test of memory consumption (measured by
total memory - free - caches - buffers; 6 uwsgi workers), both
immediately after restarting Django, and after requesting `/` 60 times
with 6 concurrent requests:
| Non-lazy | Lazy app | Difference
------------------+------------+------------+-------------
Fresh | 2,827,216 | 2,870,480 | +43,264
After 60 requests | 3,332,284 | 3,409,608 | +77,324
..................|............|............|.............
Difference | +505,068 | +539,128 | +34,060
That is, "lazy app" loading increased the footprint pre-requests by
43MB, and after 60 requests grew the memory footprint by 539MB, as
opposed to non-lazy loading, which grew it by 505MB. Using wsgi "lazy
app" loading does increase the memory footprint, but not by a large
percentage.
The other effect is that processes may be served by either old or new
code during the restart window. This may cause transient failures
when new frontend code talks to old backend code.
Enable chain-reloading during graceful, puppetless restarts, but only
if enabled via a zulip.conf configuration flag.
Fixes#2559.

This replaces the TERMS_OF_SERVICE and PRIVACY_POLICY settings with

With minor changes by Eeshan Garg.
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.

PostgreSQL 11 and below used a configuration file names
`recovery.conf` to manage replicas and standbys; support for this was
removed in PostgreSQL 12[1], and the configuration parameters were
moved into the main `postgresql.conf`.
Add `zulip.conf` settings for the primary server hostname and
replication username, so that the complete `postgresql.conf`
configuration on PostgreSQL 14 can continue to be managed, even when
replication is enabled. For consistency, also begin writing out the
`recovery.conf` for PostgreSQL 11 and below.
In PostgreSQL 12 configuration and later, the `wal_level =
hot_standby` setting is removed, as `hot_standby` is equivalent to
`replica`, which is the default value[2]. Similarly, the
`hot_standby = on` setting is also the default[3].
Documentation is added for these features, and the commentary on the

The upstream of the `camo` repository[1] has been unmaintained for
several years, and is now archived by the owner. Additionally, it has
a number of limitations:
- It is installed as a sysinit service, which does not run under
Docker
- It does not prevent access to internal IPs, like 127.0.0.1
- It does not respect standard `HTTP_proxy` environment variables,
making it unable to use Smokescreen to prevent the prior flaw
- It occasionally just crashes, and thus must have a cron job to
restart it.
Swap camo out for the drop-in replacement go-camo[2], which has the
same external API, requiring not changes to Django code, but is more
maintained. Additionally, it resolves all of the above complaints.
go-camo is not configured to use Smokescreen as a proxy, because its
own private-IP filtering prevents using a proxy which lies within that
IP space. It is also unclear if the addition of Smokescreen would
provide any additional protection over the existing IP address
restrictions in go-camo.
go-camo has a subset of the security headers that our nginx reverse
proxy sets, and which camo set; provide the missing headers with `-H`
to ensure that go-camo, if exposed from behind some other non-nginx
load-balancer, still provides the necessary security headers.

This is an additional security hardening step, to make Zulip default
to preventing SSRF attacks. The overhead of running Smokescreen is
minimal, and there is no reason to force deployments to take
additional steps in order to secure themselves against SSRF attacks.
Deployments which already have a different external proxy configured
will not gain a local Smokescreen installation, and running without
Smokescreen is supported by explicitly unsetting the `host` or `port`
values in `/etc/zulip/zulip.conf`.
This helps increase the probability that folks read the guidelines for how the
chat.zulip.org community works and what streams to use before arriving there.

Previously, our docs had links to various versions of the Django docs,

(1) the page still exists and has not been moved to a new location

It's better to explicitly list the possibilities. Also, the

Subscriptions unupdated. Given that similar things can be introduced in
the future for any other flag not officially supported by having a

The main tricky part has to do with what values the attribute should

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

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.
