Use sync.Once to guarantee a single close.
There was some weird queuing going on. The queue was implement by
spawning goroutines that would block on the "ticketer" until it was
their turn to write to the output channel. If N events where in the
watch when the consumer of the watch stopped reading events, N
goroutines would leak. In unit tests of the certificate manager, this
was causing ~10k goroutines to leak.
Fix it with a buffering event processor that uses only one routine and
cancels correctly.
conflict.
Adding unit test verify that deleteValidation is retried.
adding e2e test verifying the webhook can intercept configmap and custom
resource deletion, and the existing object is sent via the
admissionreview.OldObject.
update the admission integration test to verify that the existing object
is passed to the deletion admission webhook as oldObject, in case of an
immediate deletion and in case of an update-on-delete.
Errors on updates are bad because they usually come from controllers and
it's very hard to take actions on them. We also don't want to start
breaking kubernetes clusters if something in a schema happens a way we
didn't foresee (even though we've tried to be diligent and test as much
as possible, these can still happen).
Log an identifiable error when they happen. Ideally people can look in
the logs to find these and report them, or providers can look for these
in logs and make sure they don't happen.
Only conversion to internal types are going to be logged and ignored.
It means that we're still failing for:
- Version conversions. If we can't convert the object from one version
to another,
- Unions. If we can't normalize the union,
- Invalid MangedFields sent in the object. If something has changed the
ManagedFields to an invalid value.
- Failure to serialize the manager information, this really shouldn't
happen.
- Encoding the ManagedFields
