This is a common bug that users might be tempated to introduce.
And also fix two instances of this bug that were present in our
codebase, including an important one in our upgrade code path.
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.
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.
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.
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.
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.
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/.
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.
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.
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.
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:
https://docs.puppet.com/puppet/2.7/lang_defined_types.html
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.

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.
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.
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.
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
attack by default.
Sysadmins can switch this to a whitelist when they want to use frames.
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.
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.
Now, one can just set `no_serve_uploads` in `zulip.conf` to prevent
`nginx` from serving locally uploaded files.
This should help simplify the S3 integration setup process.
This option is intended to support situations like a quick Docker
setup where doing HTTPS adds more setup overhead than it's worth.
It's not intended to be used in actual production environments.
