Greg Price 6e633f8e2f install: Use readlink -f rather than realpath.
It does exactly the same thing, though the name is less transparent; and
it simplifies the script by avoiding an extra, early `apt-get install`.

Greg Price 218b653930 install: Clean up organization of option parsing.
The parsing of options from environment variables belongs right next
to the normal kind; and `show_help` was unnecessary indirection.

Greg Price 31ec9a4627 install: Implement --self-signed-cert earlier.
Otherwise when puppet tries to install and start nginx, that can
give an error.

Greg Price 70d203c1c8 install: Add experimental option to go straight through more install steps.
We'll make this the normal behavior soon, once we're satisfied with
our arrangements for sending the admin straight to realm creation and
using the app without configuring email.  The instructions in the docs
will also have to change accordingly, of course.

Greg Price 0ba3fc3c2f install: Slightly tighten up CLI parsing.
This causes us to give an error if you pass the installer any
positional arguments, e.g. with `--`.  There's no reason you'd want
to do this, but I accidentally did it by passing an extra `--` to
the `test-install/install` wrapper and spent a few minutes on
confused debugging.

Greg Price f26b34405e install --self-signed-cert: Generate our own, rather than use system's.
This gives us just one way of adopting a self-signed cert, rather than
one script which would generate a new one and an option to another
which would symlink to the system's snakeoil cert.  Now those two
codepaths converge, and do the same thing.

The small advantage of generating our own over the alternative is that
it lets us set the name in the cert to EXTERNAL_HOST, rather than the
system's hostname as embedded in the system snakeoil certs.  Not a big
deal, but might make things go slightly smoother if some browsers are
lenient (in a way that they probably shouldn't be.)

Greg Price 841a5f3152 install: Say --self-signed-cert instead of --snakeoil-cert.
Less evocative, but requires less explanation to document because
it's a well-known term on the Internet.

Greg Price 2a59b2d2ac install: Work around a bug in the (our) Debian package for camo.
Before this fix, the installer has an extremely annoying bug where
when run inside a container with `lxc-attach`, when the installer
finishes, the `lxc-attach` just hangs and doesn't respond even to
C-c or C-z.  The only way to get the terminal back is to root around
from some other terminal to find the PID and kill it; then run
something like `stty sane` to fix the messed-up terminal settings
left behind.

After bisecting pieces of the install script to locate which step
was causing the issue, it comes down to the `service camo restart`.
The comment here indicates that we knew about an annoying bug here
years ago, and just swept it under the rug by skipping this step
when in Travis. >_<

The issue can be reproduced by running simply `service camo restart`
under `lxc-attach` instead of the installer; or `service camo start`,
following a `service camo stop`.  If `lxc-attach` is used to get an
interactive shell, these commands appear to work fine; but then when
that shell exits, the same hang appears.  So, when we start camo
we're evidently leaving some kind of mess that entangles the daemon
with our shell.

Looking at the camo initscript where it starts the daemon, there's
not much code, and one flag jumps out as suspicious:

  start-stop-daemon --start --quiet --pidfile $PIDFILE -bm \
    --exec $DAEMON --no-close -c nobody --test > /dev/null 2>&1 \
    || return 1
  start-stop-daemon --start --quiet --pidfile $PIDFILE -bm \
    --no-close -c nobody --exec $DAEMON -- \
    $DAEMON_ARGS >> /var/log/camo/camo.log 2>&1 \
    || return 2

What does `--no-close` do?

 -C, --no-close
     Do not close any file descriptor when forcing the daemon
     into  the  background  (since version 1.16.5).  Used for
     debugging purposes to see  the  process  output,  or  to
     redirect  file  descriptors  to  log the process output.

And in fact, looking in /proc/PID/fd while a hang is happening finds
that fd 0 on the camo daemon process, aka stdin, is connected to our
terminal.

So, stop that by denying the initscript our stdin in the first place.
This fixes the problem.

The Debian maintainer turns out to be "Zulip Debian Packaging Team",
at debian@zulip.com; so this package and its bugs are basically ours.

Greg Price cef8549ec6 install: Add --snakeoil-cert option.
This provides a major simplification for non-production installs,
including our own testing (it's already in both the test-install
harness script and the "production" test suite) as well as potential
admins evaluating Zulip.

Ultimately this should probably be the default behavior, with perhaps
something shown to admins on the web as a reminder and link to help on
installing a better certificate.  For now, pending working through
that, just get the behavior in and leave it opt-in.

Greg Price 525b136f10 install: Install curl.
The third-party `install-yarn.sh` script uses `curl`, and we invoke it
in `install-node`.  So we need to install it as a dependency.

We've mostly gotten away with this because it's common for `curl` to
already be installed; but it isn't always.

Greg Price 64c608a51a install: Clarify how we set locale during install, and why.
This updates commit 11ab545f3 "install: Set the locale ..."
to be somewhat cleaner, and to explain more in the commit message.

In some environments, either pip itself fails or some packages fail to
install, and setting the locale to en_US.UTF-8 resolves the issue.

We heard reports of this kind of behavior with at least two different
sets of symptoms, with 1.7.0 or its release candidates:
  https://chat.zulip.org/#narrow/stream/general/subject/Trusty.201.2E7.20Upgrade/near/302214
  https://chat.zulip.org/#narrow/stream/production.20help/subject/1.2E6.20to.201.2E7/near/306250

In all reported cases, commit 11ab545f3 or equivalent fixed the issue.

Setting LC_CTYPE is redundant when also setting LC_ALL, because LC_ALL
overrides all `LC_*` environment variables; so skip that.  Also move
the line in `install` to a more appropriate spot, and adjust the
comments.

Greg Price 8f387ba4d4 setup-certbot: Add option to choose verification method.
This allows the installer to continue using this script for the
`standalone` method, while the no-argument form now uses the same
`webroot` method as the renewal cron job, suitable for running
by hand to adopt Certbot after initial install.

Greg Price ae901309fc certbot: Control auto-renew with a zulip.conf setting.
This causes the cron job to run only when a Zulip-managed certbot
install is actually set up.

Inside `install`, zulip.conf doesn't yet exist when we run
setup-certbot, so we write the setting later.  But we also give
setup-certbot the ability to write the setting itself, so that we
can recommend it in instructions for adopting certbot in an
existing Zulip installation.

include --help, and avoid printing all the `set -x` garbage before the

Tim Abbott 304bd86173 install: Support installing a Zulip server from a Git checkout.
Historically, one has needed to build a release tarball in order to
use/test the Zulip installer, but you could upgrade a Zulip server
from Git.  However, the only reason for that requirement was that we
didn't run `tools/update-prod-static` as part of the install script if
it's required.  A good test for that case is whether we're in a Git
repository, but a better one is to check whether the prod-static
content exists in the tarball paths.

Fixes #3704.

Tim Abbott 2424819749 install: Move upstart checks a bit earlier.
This should make it much more likely that users see this before
waiting a long time for other things to happen, since the `apt-get
dist-upgrade` step is really slow.  We can't move further to the top,
since this requires `lsb_release` to be installed.

Tim Abbott f5935e81c7 install: Support being run not directly from /root/zulip.
This adds a dependency on the realpath package on trusty; we could try
to remove it if needed, but given that realpath is included in
coreutils on Xenial (and presumably anything else modern), I think
it's reasonable to add it.

Tim Abbott 6496fe2a53 travis: Remove rabbitmq nodename dependency on hostname.
Because rabbitmq doesn't support changing the nodename of a running
rabbitmq node, Zulip installations suffered a plague of issues where
e.g. a Zulip server would reboot, the hostname would change, and
suddenly the local rabbitmq instance being used by Zulip would stop
working.

We address this problem by using, by default, a fixed rabbitmq
nodename, but providing server administrators the option to set the
rabbitmq nodename used by Zulip however they choose.

To upgrade an existing server to use this new configuration, one will
need to add something like the following to /etc/zulip/zulip.conf:

[rabbitmq]
nodename = zulip@localhost

However, I don't believe we have the puppet code in place to make this
work correctly at initial installation without rabbitmq-server being
already installed (but off), as we can easily setup in Travis CI but I
haven't been willing to do for the installer.  So for now, this just
fixes our Travis CI problems.

Fixes: #1579.

Tim Abbott 5bff72c385 Revert "Use apt-add-repository to setup Zulip PPA."
This reverts commit 3f95e567c1.

Apparently `apt-add-repository` fails periodically in CI.  I suspect
this is some sort of silly networking problem, but given that all
we're saving is a few lines of code, the old version was better if
this fails basically ever.

Tim Abbott 883e991adf install: Improve support for non-default puppet rules.
Previously, the install script would fail if you passed various
non-default puppet rules, since the code to configure and restart
services that runs later on in the install script largely ran
unconditionally, regardless of whether the relevant service was
actually installed on the target system.

This should make the main install script reusable for installing
e.g. a dedicated Postgres server for use with Zulip.
