rht 43bedc0909 provision: Use vendored pg_hba.conf on CentOS. 2018-12-16 13:21:54 -08:00
rht c9d54f7854 puppet: Remove vendored puppetlabs apt and stdlibs dependencies.
This commit works by vendoring the couple functions we still use from
puppetlabs stdlib (join and range), but removing the rest of the
puppetlabs codebase, and of course cleaning up our linter rules in the
process.

Fixes #7423.

rht d2aa81858c puppet/zulip_ops: Replace apt::source with setup-apt-repo-debathena.
Tweaked by tabbott to use a clearer name.

Tim Abbott b218c2a70e loadbalancer: Use same certbot cert for zulipstaging.com.
This is a simple configuration improvement.

Tim Abbott 467694c1fa nginx: Enable http2 in external nginx configuration.
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.

Tim Abbott e609e10229 puppet: Fix missing dependency of tsearch-extras on apt repository.
This isn't super required, in that we add these repositories via
`setup-apt-repo` in any case, but the previous code was wrong and
worth fixing in any case.
2018-11-30 10:45:04 -08:00
Tim Abbott ededdc512b nginx: Fix missing API authentication configuration.
This fixes a bug where our API routes for uploaded files (where we
need to use a consistent URL between session auth and API auth) were
not properly configured to pass through the API authentication headers
(and otherwise provide REST endpoint settings).

In particular, this prevented the Zulip mobile apps from being able to
access authenticated image files using these URLs.

Tim Abbott f62050212b tornado: Fix supervisord configuration for multiple processes.
Apparently, we can use the process group naming style of having dashes
in the names without using the explicit nun_procs feature of
supervisord configuration.

The new configuration is perfectly satisfactory, so there's no real
reason to prefer the old approach.

Tim Abbott a5acbd51c3 settings: Add new zulip.conf setting for number of Tornado processes.
This will eventually be used to support Tornado sharding; for now,
it's just used to contain the code intended to support that feature.

Tim Abbott dc7d44a245 puppet: Don't run calculate-first-visible-message-id on most systems.
This should only be run on systems that are running zilencer, because
the cron job is part of the zilencer project.
2018-10-30 11:40:24 -07:00
Tim Abbott a4df001cef check_queue_worker_errors: Add support for running unprivileged.
Previously, this script needed access to Django settings, which in
turn required access to /etc/zulip/zulip-secrets.conf.  Since that
isn't world-readable, this meant that this couldn't run as an
unprivileged `nagios` user.

Fix that by just hardcoding the appropriate path under /var/log/.
2018-10-18 15:03:17 -07:00
Tim Abbott 98d89b676d pg_backup_and_purge: Fix incorrect conversion to use python3 types.
When using the Python 3 typing style, Python scripts can't import from
typing inside an `if False` (in contrast, one needs to import inside
an `if False` to support the Python 3 syntax without needing
python-typing installed).  So this was just incorrectly half-converted
from the Python 2 style to the Python 3 style.
2018-10-16 11:12:52 -07:00
Tim Abbott 2c7f9ce0fc puppet: Fix puppet-lint warnings in various manifests.
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.

Tim Abbott 5021f7b76f puppet: Fix accidental conflict on apache2 package.
Apparently, the work to force installation of the Python 3 version of
mod_wsgi was buggy and tried to force uninstall apache2.

Tim Abbott db1f706d09 pg_backup_and_purge: Fix buggy recovery status parsing.
This was converted to Python 3 incorrectly, in a way that actually
completely broke the script (the .decode() that this adds is critical,
since 'f' != b'f').

We fix this, and also add an assert that makes the parsing code
safer against future refactors.

Aditya Bansal 5bfe24beef puppet-lint: Fix an error with defined type safepackage in base.pp.
We fix "ERROR: safepackage not in autoload module layout" error
which was caused by a defined type "safepackage" definitation
lying in the wrong place. We refactor to create the defined type
according to puppet guidelines. Link below:

Aditya Bansal 710d4507de puppet-lint: Fix lines longer than 140 characters lint warnings.

Tim Abbott 7853254df7 puppet: Run thumbor by default on voyager systems.
With this change, all that one needs to do to start using thumbor in
production is to set the `THUMBOR_URL` setting.

Since without THUMBOR_URL enabled, the thumbor service doesn't
actually do anything, this is pretty safe.
2018-07-30 16:16:52 -07:00
Tim Abbott 02ae71f27f api: Stop using API keys for Django->Tornado authentication.
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.

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.

Tim Abbott afdfdf775c nginx: Set X-Frame-Options header to DENY.
While there are legitimate use cases for embedded Zulip in an iFrame,
they're rare, and it's more important to prevent this category of

Sysadmins can switch this to a whitelist when they want to use frames.

Tim Abbott 9b4b15cd0a static_asset_compiler: Remove dependency on node packages.
We no longer need or use these, since Zulip installs a pinned version
of node directly with the scripts/setup/install-node tool.

Noticed because in the effort of adding Ubuntu bionic support, we
noticed the package names changed again.
2018-05-24 09:43:45 -07:00
Tim Abbott c843276196 nginx: Fix accidental load-balancing between IPv4 and IPv6.
Apparently, our nginx configuration's use of "localhost", combined
with the default in modern Linux of having localhost resolve to both
the IPv4 and IPv6 addresses on a given machine, resulted in `nginx`
load-balancing requests to a given Zulip server between the IPv4 and
IPv6 addresses.  This, in turn, resulted in irrelevant 502 errors
problems every few minutes on the /events endpoints for some clients.

Disabling IPv6 on the server resolved the problem, as does simply
spelling localhost as 127.0.0.1 for the `nginx` upstreams that we
declare for proxying to non-Django services on localhost.

Tim Abbott 9498260516 puppet: Include process_fts_updates in dockervoyager manifest.

Tim Abbott eab1d1d9e7 puppet: Fix puppet-apt bug with modern apt-key.
With modern apt-key, the fingerprints are displayed in the more fully

This fixes some unnecessary work being done on each puppet run on
Debian stretch.

I would have preferred to not need to do this by upgrading to
upstream, but see #7423 for notes on why that isn't going to work
(basically they broke support for puppet older than 4).

Tim Abbott 7fe19ef8e7 puppet: Remove </% example characters from sample postgres config.

content from the base postgres config file.

Tim Abbott 63fe39e381 zulip_ops: Disable Ubuntu's built-in update-motd.d files.
We can't really do this in the zulip manifests (since it's sorta a

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.

This allows users to configure a mailname for postfix in
/etc/zulip/zulip.conf

Aditya Bansal 4898fe7ebc uploads: Change Content-Security-Policy to fix issue with pdf's.
Our recent addition of Content-Security-Policy to the file uploads
backend broke in-browser previews of PDFs.

The content-types change in the last commit fixed loading PDFs for
most users; but the result was ugly, because e.g. Chrome would put the
PDF previewer into a frame (so there were 2 left scrollbars).

There were two changes needed to fix this:
* Loading the style to use the plugin.  We corrected this by adding
  `style-src 'self' 'unsafe-inline';`
* Loading the plugin.  Our CSP blocked loading the PDf viewer plugin.
  To correct this, we add object-src 'self', and then limit the
  plugin-type to just the one for application/pdf.

We verified this new CSP using https://csp-evaluator.withgoogle.com/
in addition to manual testing.

Tim Abbott 568a12e254 nginx: Add PDF files to the content-types list.
Previously, user-uploaded PDF files were not properly rendered by
browsers with the local uploads backend, because we weren't setting
the correct content-type.
2018-04-17 11:50:10 -07:00
Tim Abbott a463743107 puppet: Add Content-Security-Policy for user avatars.
This adds a basic Content-Security-Policy for user-uploaded avatars
served by the LOCAL_UPLOADS backend.

I think this is for now an unnecessary follow-up to
d608a9d315, but is worth doing because
we may later change what can be uploaded in the avatars directory.
2018-04-10 14:43:08 -07:00
Aditya Bansal d608a9d315 uploads: Add Content-Security-Policy for user uploads.
This adds a basic Content-Security-Policy for user-uploaded files with local uploads.

While over time, we plan to add CSP for the main site as well, this CSP is particularly
important for the local-uploads backend, which often shares a domain with the main site.
2018-04-09 14:43:02 -07:00
Tim Abbott 0d35bbc464 install: Install the wget package.
We depend on it for installing node, and it's a standard package, not
a required one, so we do need to explicitly declare the dependency.
2018-03-29 16:03:44 -07:00
Ghislain Antony Vaillant 00dd86967b puppet: Add Debian 9 package names to definitions.
This doesn't add support for Debian 9, but it will save time for folks
working on Stretch support in the future.

neiljp (Neil Pilgrim) 090b47ed19 mypy: Add explicit Optional for default=None parameters in various files. 2018-03-28 12:31:51 -07:00
neiljp (Neil Pilgrim) f32f3cbf72 mypy: Amend zulip-ec2-configure-interfaces to avoid None. 2018-03-23 11:39:54 -07:00
Tim Abbott d98be2f19f puppet: Only run analytics Nagios checks on machine running cron.
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.
2018-03-06 13:38:27 -08:00
Tim Abbott 8e8faab006 puppet: Move clearsessions cron job to app_frontend_once.
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.
2018-03-06 13:35:51 -08:00
Tim Abbott 9a74ef5056 puppet: Move some cron jobs to app_frontend_once.pp.
Several cron jobs had incorrectly ended up in the app_frontend.pp
template, and thus would only run on voyager instances.
2018-03-06 13:35:51 -08:00
Tim Abbott 3ae645ed12 puppet: Rename analytics.pp to app_frontend_once.pp. 2018-03-06 13:35:51 -08:00
Tim Abbott ad7f38ab3b puppet: Move analytics cron job to analytics.pp.
This better groups it with the related code.
2018-03-06 13:35:51 -08:00
Tim Abbott 24b6106c9c puppet: Dsiable checking for evictions in memcached nagios.
Zulip's caching model for message history is such that it is normal
and healthy for there to eventually be a nontrivial volume of
evictions.

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.
