Apparently, we weren't returning the `json_error`, resulting in users
encountering this condition receiving a 500, rather than the proper
40x error.
This fixes a regresion introduced in 9ae68ade8b.
Zulip doesn't previously make use of the standard Django is_staff flag
(in that the Django admin site is disabled), but since conceptually
the /activity page would be part of the Django admin site if we were
using it (i.e. for server-level administrators), it makes sense to key
off of that rather than the previous, fragile, check for the realm
domain name.
Previously, we rejected the HEAD requests that the trello integration
uses to check if the server accepts the integration.
Add decorator for returning 200 status code if request is HEAD.
Fixes: #2311.
This ensures that everything is using the correct subdomain for
requests. While it probably wouldn't be a real security problem for
the wrong subdomain to work, this enforcement is essential to catching
bugs in the product and users' API scripts.
This adds support for running a Zulip production server with each
realm on its own unique subdomain, e.g. https://realm_name.example.com.
This patch includes a ton of important features:
* Configuring the Zulip sesion middleware to issue cookier correctly
for the subdomains case.
* Throwing an error if the user tries to visit an invalid subdomain.
* Runs a portion of the Casper tests with REALMS_HAVE_SUBDOMAINS
enabled to test the subdomain signup process.
* Updating our integrations documentation to refer to the current subdomain.
* Enforces that users can only login to the subdomain of their realm
(but does not restrict the API; that will be tightened in a future commit).
Note that toggling settings.REALMS_HAVE_SUBDOMAINS on a live server is
not supported without manual intervention (the main problem will be
adding "subdomain" values for all the existing realms).

This exists primarily in order to allow us to mock settings.DEBUG for
the purposes of rate limiting, without actually mocking
settings.DEBUG, which I suspect Django never intended one to do, and
thus caused some very strange test failures (see
https://github.com/zulip/zulip/pull/776 for details).
If settings.RATE_LIMITING is False, short circuit rate
limiting earlier in rate_limit(). This change particularly
avoids inspect request.user and possibly spamming the error
log for sites that don't care about rate limiting.
Like the recent change blocking JSON endpoints for deactivated users
and users in deactivated realms, this change is a hardening
improvement. Those users should be unable to get an active session
anyway, but if somehow one is leaked, this means they won't be able to
access any user data.
While in theory users should be unable to get a valid session in order
to access these endpoints in the first place, this provides an extra
layer of hardering to prevent a deactivated user with a session from
accessing data via the old-style JSON API.
In a deactivated realm, webhooks would still successfully send
messages, since there was no check for whether the realm was active in
api_key_only_webhook_view.
