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 8d86a6e331 install: Slightly clean up another couple of bits of style. 2018-02-08 17:14:28 -08:00
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 f68c485a86 install: Clean up some shell style: use here-docs, and compact getopt. 2018-02-08 17:05:13 -08:00
Greg Price 8f4b7f6e1e install: On --express, check up front for --hostname and --email. 2018-02-08 16:34:49 -08:00
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 d76c2d77f4 install: Tighten an SSL-cert help message.
The option's name now explains for itself some of what we'd
had in prose.

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 c27f36a82a install: Rename generate-self-signed-cert.
This script generates one certificate.

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.

Tim Abbott 15cf87f424 clean-npm-cache: Fix path to yarn in Travis CI.
Apparently, this was checking the wrong path in Travis CI, and thus
never actually running (meaning we'd accumulate every `node_modules`
directory ever in the Travis caches, which in turn resulted in very
slow builds).

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.

Harshit Bansal e75f0c1ee4 requirements: Rename requirements files.
This commit renames various source requirements files like `dev.txt`,
`mypy.txt` etc to `dev.in`, `mypy.in` etc and various locked requirements
files like `dev_lock.txt`, `mypy_lock.txt` etc to `dev.txt`, `mypy.txt`
etc. This will help in emphasizing to the user that *.in are actually
input to `update-locked-requirements` tool which should be run after
updating any of these.

Aditya Bansal dd037df2c4 thumbor: Add dependencies and virtualenv setup script.
In this commit we add new dependencies needed for running thumbor.
Also we add the script for creating the virtual environment ready
for thumbor.
Note: Thumbor will use python2 and thus have different virtualenv
dedicated to it.
Credits to @TigorC and @joshland as well for there work on this.

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 84f956f5f1 certbot: Use --deploy-hook to get the cert actually served.
Certbot replaces the cert files under /etc/letsencrypt/live/,
which our nginx config refers to symlinks to; but it doesn't
tell nginx there's been an update, so nginx keeps serving the
old cert.

This is fine as long as nginx is restarted, or just told to
reload its config, at some point before the cert actually
expires about 30 days later.  Which is probably the common
case, but of course we should make it just work.  So, if we
actually renew a cert, tell nginx to reload its config now.

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.

Except in:

For the latter two, because they might be yanked away to a separate repo
for general use with other FLOSS projects.
