Now that every call site of check_subdomain produces its second
argument in exactly the same way, push that shared bit of logic
into a new wrapper for check_subdomain.
Also give that new function a name that says more specifically what
it's checking -- which I think is easier to articulate for this
interface than for that of check_subdomain.
The refactor in b46af40bd3 didn't
correctly translate the code for managing request.user and
request._email, resulting in requests for the push notification
bouncer being rejected with this exception:
AttributeError: 'AnonymousUser' object has no attribute 'rate_limits'
Previously, Zulip's server logs would not show which user or client
was involved in login or user registration actions, which made
debugging more annoying than it needed to be.
This fixes the significant duplication of code between the
authenticate_log_and_execute_json code path and the `validate_api_key`
code path.
These's till a bit of duplication, in the form of `process_client` and
`request._email` interactions, but it is very minor at this point.
The old iOS app has been gone from the app store for 8 months, never
had a huge userbase, and its latest version didn't need this hack. So
this code is unlikely to do anything in the future; remove it to
declutter our authentication decorators codebase.
The check itself was correct, but the error message was in fact the
opposite of what this check is for. In other words, the only things
these users can do is post messages, and the error message when you
tried to do something else was to tell you that the user can't post
messages.
This technically changes the behavior in the case that
!settings.ZILENCER_ENABLED but is_remote_zulip_server(role).
Fortunately, that case is mostly irrelevant (in that remote zulip
servers is a Zilencer feature). The old behavior was also probably
slightly wrong, in that you'd get a zilencer-specific error message in
that case.
The whole thing is an error, so "message" is a more apt word for the
error message specifically. We abbreviate that as `msg` in the actual
HTTP responses and in the signatures of `json_error` and friends, so
do the same here.
Exception logging within api_key_only_webhook_view fails when
ValueError is raised if the request.body passed to ujson.loads
isn't valid JSON. In this case, we now just convert the payload
to a string and log that. This allows us to inspect JSON payloads
that aren't being decoded properly.
