Tim Abbott 9423f8e31c node cache: Don't shell out to yarn to get the version.
This can easily be done by just reading the package.json file and
extracting the version value, just like we now do in install-node.

Tim Abbott 630968b632 provision: Use a more efficient approach for getting yarn version.
Since yarn has a package.json conveniently available, we can parse
that with jq, saving the expensive operation of starting up yarn.

This saves ~300ms in a no-op provision.

rht a1ca8c262a setup-apt-repo: Add `set -e` and ensure the sources file exists. 2018-12-07 14:00:59 -08:00
Tim Abbott b3a4b78c6d puppet: Pass zulip scripts path as a FACTER to puppet.
This makes it possible for the Puppet codebase to access the path to
the relevant /home/zulip/deployments type directory that puppet was
run from, which in turn makes it possible to safely call scripts from
here.

Based on work by Rein Zustand.

Tim Abbott e13de3e629 scripts: Fix incorrect garbage-collection of emoji/node caches.
Apparently, we were incorrectly expressing the paths in the
caches_in_use data structures for these two cache-cleaning algorithms,
resulting in the default threshhold_days algorithm controlling which
caches could be garbage-collected.  While the emoji one was just a
performance optimization for upgrade-zulip-from-git, it was possible
for the main `node_modules` cache in use in production to be GCed,
resulting in LaTeX rendering being broken.

Tim Abbott 1303f8df20 docs: Fix missing quotes in `su zulip -c` documentation.
This fixes an actual user-facing issue in our mobile push
notifications documentation (where we were incorrectly failing to
quote the argument to `./manage.py register_server` making it not
work), as well as preventing future similar issues from occurring
again via a linter rule.

Tim Abbott 31556e45d8 setup-apt-repo: Install gnupg as part of installation.
Apparently, on Debian stretch, the gnupg package isn't installed by
default, which means that our `apt-key add` commands were failing with
these errors on an ultra-minimal Debian installation:

+ apt-key add ./scripts/setup/packagecloud.asc
E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation
+ apt-key add ./scripts/setup/pgroonga-debian.asc
E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation

Fixes #10480.

Previously, we unconditionally tried to restart the Tornado process
name corresponding to the historically always-true case of a single

restarted on a production deployment on servers with more than one
Tornado process configured.

Tim Abbott adf27aae4c python: Remove now-unnecessary str_utils library.
This library was absolutely essential as part of our Python 2->3

This commit allows specifying Subject Alternative Names to issue certs

names are then added to the SAN field. All of these arguments are now
positional. Also read the following for the certbot syntax reference:

Tim Abbott 453c35d0f7 install: Provide a suggestive error message when missing Universe.
By far the dominant cause of errors when installing apt packages is
not having the Universe repository enabled in Ubuntu bionic (this
seems to have started happening a lot recently; I wonder if Ubuntu
changed the defaults for new server installs or something?).

In any case, providing that suggestion in the error output should help
reduce these a lot.

Tim Abbott 3f03dcdf5e nagios: Support multiple tornado processes.
This allows our Tornado monitoring to correctly report whether
multiple configured Tornado processes are running.

This setup isn't ideal, in that it can't detect cases where the wrong
set of Tornado processes are running, but it's nice and simple and
should catch most actual problems.

Shubham Padia 5ea7feee7e upgrade-zulip-from-git: Support specifying tag or commit ID for refname.
Fixes #10706.
Issue: Before this commit, the `refname` positional argument to
`upgrade-zulip-from-git` script would run successfully for a branch
name on the given remote, but the script would fail if it was
provided with a tag or commit ID.
Solution: 'git clone -q -b refname LOCAL_GIT_CACHE_DIR deploy_path`
would be split into two commands:
1.) `git clone -q LOCAL_GIT_CACHE_DIR deploy_path`
2.) `git checkout -b deploy_timestamp refname` which makes a new
branch with the same name as the timestamp used in make_deploy_path.

Tim Abbott a7d7d181ea install: Ensure that sudo is installed.
We use it to drop privileges from root to other users in the installer
process (which ideally, we would remove, but it will take some
annoying refactoring).

This should generally be safe to do, since the default sudo
permissions only allow root to use it anyway.

issue of removing the need to do this.

Tim Abbott 608173657d upgrade-zulip: Clean up legacy google emoji icons.
Because we renamed the "google" iconset to be the modern Google set,
not what is now called the "googleblob" icon set, we need to make sure
that our usually correct policy of not overwriting image files under
`prod-static/` doesn't apply to files potentially being copied in for
the emoji images.

We fix this by just deleting the `images-google-64` directory on
upgrade if it contains the googleblob version of the "hotdog" emoji.

Fixes #10038.

Tim Abbott 9054ce278f locale: Fix incorrect use of locale-gen to generate locales.
Previously, we were having issues installing on Debian Stretch with
non-English locales, because `locale-gen` actually doesn't take a

We should instead be calling localedef directly.

Tim Abbott 35cb7528f9 models: Add new UserMessage flag active_mobile_push_notification.
This flag is used to track which user/message pairs correspond to an
active mobile push notification, that should potentially be cleared
when the user reads the message.

This flag should never appear on a message that is also marked as
read; eventually we may want a cron job to check for that condition.

We include a partial index on UserMessage for this flag.

Tim Abbott b564976ce4 upgrade-zulip: Fix unicode issues with detecting early migrations.
Apparently, our Python 3 conversion for the early-migrations logic
here was incorrect, and as a result we never set
need_create_large_indexes to True (because we were checking whether a
`bytes` was inside a list of `str`s).

The simplest fix would be to just add a `.decode()` in one place, but
this refactor to just decode at the beginning is a lot more readable.

Shubham Padia bf6dc4472b models: Add is_private flag to UserMessage and add index for it.
The is_private flag is intended to be set if recipient type is
'private'(1) or 'huddle'(3), otherwise i.e if it is 'stream'(2), it
should be unset.

This commit adds a database index for the is_private flag (which we'll
need to use it). That index is used to reset the flag if it was
already set. The already set flags were due to a previous removal of
is_me_message flag for which the values were not cleared out.

For now, the is_private flag is always 0 since the really hard part of
this migration is clearing the unspecified previous state; future
commits will fully implement it actually doing something.

History: Migration rewritten significantly by tabbott to ensure it
runs in only 3 minutes on chat.zulip.org.  A key detail in making that
work was to ensure that we use the new index for the queries to find
rows to update (which currently requires the `order_by` and `limit`
clauses).

Anders Kaseorg a5407e1c7d scripts: Replace node-wrapper with a symlink.
Commit 00e057bf44 (#4727) simplified
node-wrapper to a one-line wrapper script for performance.  Copying
the binary was proposed and rejected because node finds some of its
modules relative to its own path.  But a symlink doesn’t have that
issue, as you can verify with

    node -e 'console.log(require.resolve.paths("foo"))'

(To find its own path, node uses `process.execPath`, which resolves
symlinks, and there’s no plausible reason for that behavior to change.

Apparently, perl at least expects LANG, LANGUAGE, and LC_ALL to be

Tim Abbott 3cc93fd721 setup_venv: Fix missing libssl-dev dependency.
We were already correctly including libssl-dev in Zulip's dependencies
in development environment provisioning, but (at least now) it's
needed to build certain Python packages like pycurl when building a
Zulip virtualenv in production.  I haven't investigated why we didn't
need this on Ubuntu, but one possible reason would be that some other
library in our dependencies list happens to depend on it on Ubuntu.

We fix this by moving the dependency over to the shared
VENV_DEPENDENCIES list.

Joshua Schmidlkofer b1a57d144f thumbor: Add production installer/puppet support.
This commits adds the necessary puppet configuration and
installer/upgrade code for installing and managing the thumbor service
in production.  This configuration is gated by the 'thumbor.pp'
manifest being enabled (which is not yet the default), and so this
commit should have no effect in a default Zulip production environment
(or in the long term, in any Zulip production server that isn't using
thumbor).

Credit for this effort is shared by @TigorC (who initiated the work on
this project), @joshland (who did a great deal of work on this and got
it working during PyCon 2017) and @adnrs96, who completed the work.

2) Build the new image
3) Edit docker-compose.yml to use the new image id

Tim Abbott 8a66b0b9a9 docker: Set has_appserver=0 correctly.
The docker installer configuration incorrectly had has_appserver set
to 0; this meant that (A) the docker-zulip code needed to copy the
block of code in the installer for the `has_appserver` case into the
Dockerfile (unnecessarily), and (B) one couldn't use `install` from a
Git ref (because the static asset compiler didn't end up in the right
place).

It appears that docker-zulip tried to set this flag in their `install`
command line, but the construction inside `install` meant that didn't
work.

Greg Price e8be968250 install: Expand error message for missing SSL cert slightly.
It wasn't obvious reading this message that you can perfectly well
bring your own SSL/TLS certificate; unless you read quite a bit
between the lines where we say "could not find", or followed the link
to the detailed docs, the message sounded like you had to either use
--certbot or --self-signed-cert.

So, explicitly mention the BYO option.  Because the "complete chain"
requirement is a bit tricky, don't try to give instructions for it
in this message; just refer the reader to the docs.

Also, drop the logic to identify which of the files is missing; it
certainly makes the code more complex, and I think even the error
message is actually clearer when it just gives the complete list of
required files -- it's much more likely that the reader doesn't know
what's required than that they do and have missed one, and even then
it's easy for them to look for themselves.

Tim Abbott 7b2c9223e7 clean-npm-cache: Fix buggy garbage-collection logic.
We saw issues with /srv/zulip_npm_cache being cleaned incorrectly by
this tool in production (more correctly, we noticed broken symlinks to
those directories, even from the current deployment).  Print-debugging
showed that indeed older deployments were being ignored, because the
logic for `get_caches_in_use` was totally broken (this was sorta
masked because we also keep the last week's deployments).

The specific bug here turned out to be that we weren't passing the
`production` argument to generate_sha1sum_node_modules, but the
broader problem is that this logic isn't robust to changes in the
hashing algorithm.

Fix this by replacing the broken logic for trying to compute the
correct hash for that deployment with just checking the symlink inside
the deployment to let it self-report.

We can't easily do this same change for clean-venv-cache, because we
use multiple virtualenvs there.  But a similar change could be useful
for the emoji cache as well.

The installation isn't really complete here, and wasn't even when this

next step in the installation.

These instructions don't say what to do in an actual use case for this
option, but decent instructions there will require having a concrete
use case in front of us and designing the flow for it.  At this stage,
just say where we are in the normal flow, and an admin who's chosen to
go off that flow can figure out how they want to vary it from there.

Greg Price f22712e8e8 install: Go straight through by default.
This flips the experimental `--express` option to be the default.

We retain the old behavior, where the script exits before
`initialize-database`, as an option `--no-init-db`; it might be useful
in e.g. a migration scenario (from a Zulip install elsewhere, or
another chat system) where the admin wants to set up the database
separately.

The install instructions are adjusted to match, getting shorter by two
steps and a bunch of words.  I think this opens up opportunities to
refactor the text to simplify things further, too, but leaving that
for another commit.

Also tweak the "production" test suite to match.

Greg Price 4475950ddf queue: Restore prematurely-cut upgrade path.
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.

Aditya Bansal a137ed9e27 thumbor: Fix issue with dependencies.
We do the following here:
* Remove libjasper-dev from THUMBOR_VENV_DEPENDENCIES.
Reason: This dependancy wasn't really needed by us for using
thumbor. It was a dependancy for using open-cv as Imaging Engine
in thumbor but we use PIL (Pillow now) as Imaging Engine.
* Add zlib1g-dev, libfreetype6-dev to THUMBOR_VENV_DEPENDENCIES.
Reason: These are dependancies of Pillow which are required for it
Pillow to function. Since we use Pillow in thumbor as Imaging Engine
we need these. Stuff before this didn't break because we also use
Pillow in development Environment and have these dependancies
installed from VENV_DEPENDENCIES as well.

Umair Khan 8b33c46165 i18n: Add script to process mobile locales.
This script iterates over all the mobile.json resources and creates a
single file at static/locale/mobile_info.json which contains total and
not-translated strings information against each language. After doing
this, it deletes all the mobile i18n resources downloaded by
tools/sync-translations because we neither want to check them in our
repository nor we want to make our repository dirty.

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 0f836f51a5 generate-self-signed-cert: Fix a mostly-harmless bug.
Thanks to the magic of `set -x`, I noticed this:
```
+ cat
++ ssl-cert
/tmp/src/zulip-server/scripts/setup/generate-self-signed-cert: line 49: ssl-cert: command not found
+ apt-get install -y openssl
[...]
```

In other words, we were trying to run `ssl-cert` -- the name of a
Debian package I meant to refer to in a comment inside the templated
temporary config file for `openssl req` -- as if it were a command.
It wasn't, hence the error.

Because `set -e` has loopholes like a sieve, this didn't cause the
script to exit, just produced this funny output and presumably caused
the config file's comment to be missing a word.  In principle, it
could do something surprising if for some reason there were a command
named `ssl-cert` on PATH.

Fix it.

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 d258e48f3d install: Replace our generate-self-signed-certs script.
Take the core of the logic from how Debian generates the system's
/etc/ssl/certs/ssl-cert-snakeoil.pem ; that gives me more confidence
in the various config choices, and it also demonstrates a much cleaner
way to use the `openssl` tool.  Also replace the outer shell logic for
CLI and logging with a cleaner version.

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 ac88f8ae1b setup-certbot: Stop automatically "agreeing" to the LE TOS.
It's not appropriate for our script to pass the `--agree-tos` flag
without any evidence of the user actually having any knowledge of,
let alone intent to agree to, any such ToS.  Stop doing that.
Fortunately this script hasn't been part of any release, so it's
likely that no users have gone down this path.

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.
