This needs to be deployed on both prod and lb0 to be functional
DEPLOY INSTRUCTIONS: restart carefully
(imported from commit d97a450754608357418c80e5b3c7b3bbcd1d09fb)
This is safe because we have the wildcard-all cert.
DEPLOY INSTRUCTIONS: Change the CNAME in R53 for external-content.zulipcdn.net
to the same as www.zulip.com

Thanks Tom Cook for getting these through Digicert!
We no longer need separate wildcard certificates, etc, because we have SAN star
certs.

This allows us to specify different rules for the zmirror machines, which need
ports open for Zephyr.

This removes "X-Frame-Options DENY" from our nginx config. We need to be able
to load Zulip in an iframe for embedding and we decided that it doesn't actually
provide much protection.

We apparently still have some process that occationally sits idle in a
transaction for a while, which makes this alert super noisy.
(imported from commit 074b04ad746bac0da1b8714763538d1ce22da64e)
Doing so requires superuser privileges because check_postgres.pl only connects
to one database for that action. We could theoretically work around this, but I
don't think it's worthwhile for non-production DBs.

We believe these will generally no longer be disruptive now that we have
autocommit enabled.
(imported from commit c8c1301e0d4b188d6708173cd8c8b16279e3d910)
This requires a puppet apply on prod, as well as manually
updating the symlinks of Zulip-latest and Humbug-latest on
prod0
(imported from commit c5ef8cd0e2d156144531b35af9a8c5226f5bf750)
To deploy this, the zulip_internal::base and zulip_internal::munin classes must
be added to nagios.zulip.net.

Before we deploy this commit, we must migrate the data from the staging redis
server to the new, dedicated redis server. The steps for doing so are the
following:
* Remove the zulip::redis puppet class from staging's zulip.conf
* ssh once from staging to redis-staging.zulip.net so that the host key is known
* Create a tunnel from redis0.zulip.net to staging.zulip.net
* zulip@redis0:~$ ssh -N -L 127.0.0.1:6380:127.0.0.1:6379 -o ServerAliveInterval=30 -o ServerAliveCountMax=3 staging.zulip.net
* Set the redis instance on redis0.zulip.net to replicate the one on staging.zulip.net
* redis 127.0.0.1:6379> slaveof 127.0.0.1 6380
* Stop the app on staging
* Stop redis-server on staging
* Promote the redis server on redis0.zulip.net to a master
* redis 127.0.0.1:6379> slaveof no one
* Do a puppet apply at this commit on staging (this will bring up the tunnel to redis0)
* Deploy this commit to staging (start the app on staging)
* Kill the tunnel from redis0.zulip.net to staging.zulip.net
* Uninstall redis-server on staging
The steps for migrating prod will be the same modulo s/staging/prod0/.

This allows the utility to run on trac.zulip.net, which doesn't have a 'zulip'
database.
(imported from commit c8eabb89e5e161191d6f2c92ca2b1428b17a9aa0)
We don't do the sequence check because that requires read access to the database
itself, which the zulip user doesn't have.

We cannot use SNI for these legacy domains because old plugins still
connect to them.
This commit (along with the three previous commits) requires a lb0 nginx
deployment to function.
(imported from commit f47f3d7b597666508b3817d965fe8ce19d50c2c0)
To deploy, the certs need to manually be copied to lb0's /etc/ssl/certs
directory, the nginx config updated, and the server restarted
(imported from commit c70c7678cd010a1b2b0aba830ab3d862005bd627)
This replaces the old www.humbughq.com cert.
Contains these hostnames:
* www.humbughq.com
* api.humbughq.com
* humbughq.com

These are redirect hosts, so they don't need their own IP. Supporting
non-SNI clients isn't a priority for us.
(imported from commit b1a8de8763ab944885518c868e4e30307d84c11d)
This will let us do normal puppet applies on our postgres hosts again.
Crudini is already installed and /etc/zulip/zulip.conf has already been edited
on the relevant hosts.

MIT implemented NTP rate-limiting to defend against on-going reflection attacks,
which was causing our nagios checks to fail intermittently. When the attacks
die down or when external sites fix their NTP configurations, checking against
time.mit.edu will stop failing. However, there also isn't much of a reason to
stick with checking against a single server.
(imported from commit 2c2a1a04646b880b010cbb4b6d94016b1eccd1a0)
This reqires a puppet apply as well as a manual move of the installed
files and symlink switch. Leo will do it when it hits master.

It's confusing to have our log data on different files on different
systems (e.g. loadbalancer vs. app).
(imported from commit be701072ee05e2659f146b226a39f33cb4707180)
This tool is a little crude; it runs out of a cron job and will
forward to staging a notice about any new lines in the declared log
files, truncating if there are more than 10 lines.

Manual deployment instructions:
On staging, do a puppet apply.
No action needs to be taken for the prod deploy.

They were being installed as executable anyway, but this will make
running them manually a bit easier.

The trailing "/" actually means "replace the location with /", which
is either useless or actively harmful, depending on the location.

Previously we sometimes set it to $proxy_add_x_forwarded_for and other
times to $remote_addr, but according to
http://wiki.nginx.org/HttpProxyModule#.24proxy_add_x_forwarded_for
$proxy_add_x_forwarded_for handles this for us -- it will be
$remote_addr if there was no X-Forwarded-For header anyway.

We now have 2 variablse:
EXTERNAL_API_PATH: e.g. staging.zulip.com/api
EXTERNAL_API_URI: e.g. https://staging.zulip.com/api
The former is primarily needed for certain integrations.

This is something we forgot to do in the VPC migration, so our IPs
have all been the lb0 IP in our logs :(.
(imported from commit 9d3fc69cf72a84f7bd7c54e50fb1e776a67d971f)
This requires a puppet apply on prod0, and an update of the
Zulip-latest.dmg and Humbug-latest.dmg symlinks in
/src/www/dist/apps/mac and /srv/www/dist/apps/sso/mac
(imported from commit e83170a19ac2de6458a0fd43140068fab4135483)
This requires a puppet apply, and also a manual update of
the Zulip-latest.* symlinks in /srv/www/dist/apps

You must run
autossh -2 -fN -M 20018 -L 5009:localhost:4949 nagios@postgres2.zulip.net
as nagios on nagios.zulip.net after deploying this commit.
(imported from commit bd8a61f99555ccf0a0010d79dbd89017aaafbb8f)
This is for the interval while staging is running in VPC and postgres
is not; we can clean up these changes once that's no longer the case.
This also updates test1's IP, which apparently someone forgot to
commit previously.
We're currently running this on prod.
(imported from commit 3feced750f643bb218d4240e9a3d5cd7116963ee)
This is to ensure that if we have an interval where we're not doing
prod deploys, we don't have to worry about worker memory leaks killing
us.
