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.

It hasn't been working for years, but more importantly, it spams up
root's mail queue so that one can't find important things in there
(e.g. the fact that the long-term-idle cron job was failing).
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.
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.
We fix these by adding ignore statements in a bunch of files
where this error popped up. We target only specific lines using
the ignore statements and not the entire files.

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.
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.
Running this on additional machines would be redundant; additionally,
the FillState checker cron job runs only on cron systems, so this will
crash on other app frontends.
While this is a different system than I'd written up in #8004, I think
this is a better solution to the general problem of cron jobs to run
on just one server.
Fixes#8004.
Revert c8f034e9a "queue: Remove missedmessage_email_senders code."
As the comment in the code says, it ensures a smooth upgrade path
from 1.7.x; we can delete it in master after 1.8.0 is released.
The removal commit was merged early due to a communication failure.
This should make it possible to use the zulip_ops base rules
successfully on chat.zulip.org. Many of the changes in this commit
are hacks and probably can be cleaned up later, but given that we plan
to drop trusty support soon, it's likely that most of them will simply
be deleted then.
This doesn't yet pass all Nagios checks correctly, and still has a few
flaws:
* The ideal setup code for the `nagios` user in the database isn't included.
* Some of the other details are a bit off; we need to split some host roles.
But it's better than nothing, and we can iterate from here.
This commit just copies all the code from MissedMessageSendingWorker
class to a new EmailSendingWorker class. All the logic to send an email
through a queue was already there. This commit only makes the logic
generic. It does so by creating a special purpose queue called
'email_senders' to send any type of email. To make
MissedMessageSendingWorker still work we derive it from
EmailSendingWorker. All the tests that were testing
MissedMessageSendingWorker now run against EmailSendingWorker.
This fixes a bug where, when a user is unsubscribed from a stream,
they might have unread messages on that stream leak. While it might
seem to be a minor problem, it can cause significant problems for
computing the `unread_msgs` data structures, since it means we need to
add an extra filter for whether the user is still subscribed, either
in the backend or in the UI.
Fixes#7095.
