We weren't compressing SVG, while at the same time were incorrectly
compressing octet-stream (Which meant downloading .tar.gz files in
Chrome would get double-compressed).
Sparkle was the auto-update system used by the legacy desktop app. We
haven't been capable of using it for auto-update in years, so there's
no reason to keep around the configuration.
The new Electron app uses a different system anyway.
Whatever dist/ functionality this had in 2014 is now served by
zulip.org, and since this serves as a sample, it should be as simple
as possible.
Previously, this was more cluttered than it needed to be.
The old limits were such that these would sometimes oscillated too
high and page erroneously. The purpose of this check is to prevent
large memory leaks, and will still achieve that with a higher limit.
This allows the Nagios user to access redis without having full access
to the redis system. Ideally, this would eventually use a password
that only has statistics read access, but I'm not sure redis supports
that.
This old puppet configuration was never really used, and regardless
hardcoded an ancient zulip.net hostname. We fix this to use the
zulipconf system to get the host domain (though not, at present, the
hostname).
If a machine is configured with no swap intentationally, that
shouldn't be a Nagios problem. This alert is intended to flag
machines which are swapping.
Arguably, we should make this a symlink, but it's probably a good idea
to have every change in the production Nagios configuration go through
the zulip-puppet-apply diff experience.
Since we've found that it's fairly frequent that we want to recommend
to developers that they upgrade to a version of Zulip from Git, it
makes sense to include that by default.
It's needed by scripts/install-yarn.sh. This hadn't been discovered
because most systems end up having curl installed even though it isn't
technically a required package.
This code empirically doesn't work. It's not entirely clear why, even
having done quite a bit of debugging; partly because the code is quite
convoluted, and because it shows the symptoms of people making changes
over time without really understanding how it was supposed to work.
Moreover, this code targets an old version of the APNs provider API.
Apple deprecated that in 2015, in favor of a shiny new one which uses
HTTP/2 to meet the same needs for concurrency and scale that the old
one had to do a bunch of ad-hoc protocol design for.
So, rip this code out. We'll build a pathway to the new API from
scratch; it's not that complicated.
Whenever you restarted supervisord services, we'd end up leaking one
process from the process_queue group, eventually resulting in running
out of memory.
Fixes#6184.
This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2. In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.
One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2. See discussion on the respective previous
commits that made those explicit. There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.
The Zulip server's settings are only available if process-fts-updates
is running is on the same server as a Zulip production deployment. So
we instead check whether we have pgroonga configured in
/etc/zulip/zulip.conf.
On `trusty` there is no package for `boto` or `gevent` on Python 3, both
of which are dependencies of `wal-e` (at the version we've pinned.) This
is something used only on database servers and only in a replication
scenario, and it doesn't involve any of our code outside the wal-e repo,
so the Python version it uses is quite independent of the Zulip
application server itself and the rest of our code. For now, keep it
explicitly on Python 2 while we move forward for most everything else.
This script in `zulip_ops` is handy for managing EC2 instances. It uses
`boto`, which isn't available in `trusty` for Python 3. The use of
`boto` here isn't particularly deep, so we could replace it with some
more manual HTTP calls if it comes to that. For now, just mark it to
stay on Python 2 while we move the app and all the rest of the ops code
(except this and another straggler or two) to Python 3.
Also make a comment on this package in the Puppet manifest clearer
about what it specifically refers to.
This consists of the `zulip_ops::stats` Puppet class, which has apparently
not been used since 2014, and a number of files that I believe were
only used for that. Also a couple of tiny loose ends in other files.
This is only actually used in our `wal-e` setup, which is in
zulip_ops::postgres_common. (In fact the only mentions of `gevent` in
our whole Git history are for `wal-e`.) So remove where we mention it
on the broader zulip::postgres_common module, and move it where it's
needed.
This follows up on 98cef0ab4 by eliminating the only dependency
outside of the `zulip_ops` Puppet tree on a system Python-library
package which isn't available in `trusty` for Python 3.
