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.

"Zulip Voyager" was a name invented during the Hack Week to open
source Zulip for what a single-system Zulip server might be called, as
a Star Trek pun on the code it was based on, "Zulip Enterprise".
At the time, we just needed a name quickly, but it was never a good
name, just a placeholder. This removes that placeholder name from
much of the codebase. A bit more work will be required to transition
the `zulip::voyager` Puppet class, as that has some migration work
involved.
This legacy cross-realm bot hasn't been used in several years, as far
as I know. If we wanted to re-introduce it, I'd want to implement it
as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.
Fixes#13533.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

This has been a spurious alert for a long time.
It's unclear that this check is useful at all, but if it spikes
dramatically above what's normal, there's perhaps still utility in
being alerted.
Since LoopQueueProcessingWorker jobs cannot be monitored by checking
for connected consumers (since they poll, rather than consuming as
events arrive), they can't be monitored with check_consumers. It's
OK, because that monitoring was redundant with monitoring for
potential growth in their queue that we have as well.

The construction `su postgres -c -- bash -c 'psql …'` didn’t behave the
way it reads, and only worked by accident:
1. `-c --` sets the command to `--`.
2. `bash` sets the first argument to `bash`.
3. `-c 'psql …'` replaces the command with `psql …`.
Thus, `su` ended up executing `<shell> -c 'psql …' bash`, where
`<shell>` is the `postgres` user’s login shell, usually also `bash`,
which then executed 'psql …' and ignored the extra `bash`.
Unconfuse this construction.
Note from tabbott: The old code didn't even work by accident, it was
just broken. The right fix is to move the quoting around properly.

Apparently, our testing environment for this configuration was broken

Fixes#11786.
The overall goal of this change is to fix an issue where on Ubuntu
Trusty, we were accidentally overriding the configuration to serve
uploads from disk with the regular expressions for adding access
control headers.
However, while investigating this, it became clear that we could
considerably simplify the mental energy required to understand this
system by making the uploads-route file be unconditionally available
and included from `zulip-include/app` (which means the zulip_ops code
can share behavior here).
We also move the Access-Control-Allow-* headers to a separate include
file, to avoid duplicating it in 5 places. Fixing this duplication
discovered a potential bug in the settings used for Tornado, where
DELETE was not allowed on a route that definitely expects DELETE.
Fixes#11758.
For users putting Zulip behind certain proxies (and potentially some

Nowm unless you specify `--fill-cache`, memcached caches will not be
pre-filled after a server restart. This will be helpful when someone
is in a hurry (e.g. if the server is down right now, or if he/she
testing a configuration change in a newly setup server), it's best to
just restart without pre-filling the cache.

This should be a nice performance improvement for browsers that
support it.
We can't yet enabled this in the Zulip on-premise nginx configuration,
because that still has to support Trusty.
This isn't super required, in that we add these repositories via
`setup-apt-repo` in any case, but the previous code was wrong and
worth fixing in any case.
This fixes a bug where our API routes for uploaded files (where we
need to use a consistent URL between session auth and API auth) were
not properly configured to pass through the API authentication headers
(and otherwise provide REST endpoint settings).
In particular, this prevented the Zulip mobile apps from being able to
access authenticated image files using these URLs.
Apparently, we can use the process group naming style of having dashes
in the names without using the explicit nun_procs feature of
supervisord configuration.
The new configuration is perfectly satisfactory, so there's no real
reason to prefer the old approach.
Previously, this script needed access to Django settings, which in
turn required access to /etc/zulip/zulip-secrets.conf. Since that
isn't world-readable, this meant that this couldn't run as an
unprivileged `nagios` user.
Fix that by just hardcoding the appropriate path under /var/log/.
When using the Python 3 typing style, Python scripts can't import from
typing inside an `if False` (in contrast, one needs to import inside
an `if False` to support the Python 3 syntax without needing
python-typing installed). So this was just incorrectly half-converted
from the Python 2 style to the Python 3 style.
Apparently, `puppet-lint` on Ubuntu trusty throws warnings for certain
quoting patterns that are OK in modern `puppet-lint`. I believe the
old Zulip code was actually correct (i.e. the old `puppet-lint`
implementation was the problem), but it seems worth changing anyway to
suppress the warnings.
We also exclude more of puppet-apt from linting, since it's
third-party code.
This was converted to Python 3 incorrectly, in a way that actually
completely broke the script (the .decode() that this adds is critical,
since 'f' != b'f').
We fix this, and also add an assert that makes the parsing code
safer against future refactors.
We fix "ERROR: safepackage not in autoload module layout" error
which was caused by a defined type "safepackage" definitation
lying in the wrong place. We refactor to create the defined type
according to puppet guidelines. Link below:

We fix these by adding ignore statements in a bunch of files
where this error popped up. We target only specific lines using

With this change, all that one needs to do to start using thumbor in
production is to set the `THUMBOR_URL` setting.
Since without THUMBOR_URL enabled, the thumbor service doesn't
actually do anything, this is pretty safe.
As part of our effort to change the data model away from each user
having a single API key, we're eliminating the couple requests that
were made from Django to Tornado (as part of a /register or home
request) where we used the user's API key grabbed from the database
for authentication.
Instead, we use the (already existing) internal_notify_view
authentication mechanism, which uses the SHARED_SECRET setting for
security, for these requests, and just fetch the user object using
get_user_profile_by_id directly.
Tweaked by Yago to include the new /api/v1/events/internal endpoint in
the exempt_patterns list in test_helpers, since it's an endpoint we call
through Tornado. Also added a couple missing return type annotations.
This commits adds the necessary puppet configuration and
installer/upgrade code for installing and managing the thumbor service
in production. This configuration is gated by the 'thumbor.pp'
manifest being enabled (which is not yet the default), and so this
commit should have no effect in a default Zulip production environment
(or in the long term, in any Zulip production server that isn't using
thumbor).
Credit for this effort is shared by @TigorC (who initiated the work on
this project), @joshland (who did a great deal of work on this and got
it working during PyCon 2017) and @adnrs96, who completed the work.
While there are legitimate use cases for embedded Zulip in an iFrame,
they're rare, and it's more important to prevent this category of
attack by default.
Sysadmins can switch this to a whitelist when they want to use frames.
We no longer need or use these, since Zulip installs a pinned version
of node directly with the scripts/setup/install-node tool.
Noticed because in the effort of adding Ubuntu bionic support, we
noticed the package names changed again.
Apparently, our nginx configuration's use of "localhost", combined
with the default in modern Linux of having localhost resolve to both
the IPv4 and IPv6 addresses on a given machine, resulted in `nginx`
load-balancing requests to a given Zulip server between the IPv4 and
IPv6 addresses. This, in turn, resulted in irrelevant 502 errors
problems every few minutes on the /events endpoints for some clients.
Disabling IPv6 on the server resolved the problem, as does simply
spelling localhost as 127.0.0.1 for the `nginx` upstreams that we
declare for proxying to non-Django services on localhost.
Now, one can just set `no_serve_uploads` in `zulip.conf` to prevent
`nginx` from serving locally uploaded files.
This should help simplify the S3 integration setup process.
This option is intended to support situations like a quick Docker
setup where doing HTTPS adds more setup overhead than it's worth.
It's not intended to be used in actual production environments.
This is preferred, since we don't currently have a way to run Django
logic on the postgres hosts with the Docker implementation.
This is a necessary part of removing the need for the docker-zulip
package to patch this file to make Zulip work with Docker.
The main purpose of this change is to make it guaranteed that
`manage.py register_server --rotate-key` can edit the
/etc/zulip/zulip-secrets.conf configuration via crudini.
But it also adds value by ensuring zulip-secrets.conf is not readable
by other users.
With modern apt-key, the fingerprints are displayed in the more fully
written-out format with spaces, and so `apt-key add` was being run
every time.
This fixes some unnecessary work being done on each puppet run on
Debian stretch.
I would have preferred to not need to do this by upgrading to
upstream, but see #7423 for notes on why that isn't going to work
(basically they broke support for puppet older than 4).
Apparently, these confused the puppet template parser, since they are
somewhat similar to its syntax, resulting in errors trying to use
these templates. It's easy enough to just remove the example
content from the base postgres config file.
We can't really do this in the zulip manifests (since it's sorta a
sysadmin policy decision), but these scripts can cause significant
load when Nagios logs into a server (because many of them take 50ms or
more of work to run). So we just get rid of them.
It seems unlikely we're going to add support for additional older
Debian-based distributions, so it makes sense to just use an else
statement. This should save a bit of busywork every time we add a new
distro.
Mostly, this involves adding the big block at the bottom and making
10 a variable so that it's easier to compare different versions of
these.
I did an audit of the configuration changes between 9.6 and 10, so
this should be fine, but it hasn't been tested yet.
