- Add DefaultStatusWatcher that wraps DynamicClient and manages
informers for a set of resource objects.
- Supports two modes: root-scoped & namespace-scoped.
- Root-scoped mode uses root-scoped informers to efficiency and
performance.
- Namespace-scoped mode uses namespace-scoped informers to
minimize the permissions needed to run and the size of the
in-memory object cache.
- Automatic mode selects which mode to use based on whether the
objects being watched are in one or multiple namespaces.
This is the default mode, optimizing for performance.
- If CRDs are being watched, the creation/deletion of CRDs can
cause informers for those custom resources to be created/deleted.
- In namespace-scope mode, if namespaces are being watched, the
creation/deletion of namespaces can also trigger informers to
be created/deleted.
- All creates/updates/deletes to CRDs also cause RESTMapper reset.
- Allow pods to be unschedulable for 15s before reporting the
status as Failed. Any update resets the timer.
- Add BlindStatusWatcher for testing and disabling for dry-run.
- Add DynamicClusterReader that wraps DynamicClient.
This is now used to look up generated resources
(ex: Deployment > ReplicaSets > Pods).
- Add DefaultStatusReader which uses a DelegatingStatusReader to
wrap a list of conventional and specific StatusReaders.
This should make it easier to extend the list of StatusReaders.
- Move some pending WaitEvents to be optional in tests, now that
StatusWatcher can resolve their status before the WaitTask starts.
- Add a new Thousand Deployments stress test (10x kind nodes)
- Add some new logs for easier debugging
- Add internal SyncEvent so that apply/delete tasks don't start
until the StatusWatcher has finished initial synchronization.
This helps avoid missing events from actions that happen while
synchronization is incomplete.
- Filter optional pending WaitEvents when testing.
BREAKING CHANGE: Replace StatusPoller w/ StatusWatcher
BREAKING CHANGE: Remove PollInterval (obsolete with watcher)
- Fix FakeDynamicClient to return an object from deletes
- Fix FakeDynamicClient to return DeepCopy to avoid mutation
- Fix InventoryClient to return a DeepCopy of the input when
dry-run is enabled.
- Add ValidationPolicy:
ExitEarly (default) - exit before apply/prune if any objects are invalid
SkipInvalid - apply/prune valid objects & skip invalid ones
- Add ValidationEvent to be sent once for every invalid object or set of
objects, when the SkipInvalid policy is selected. For ExitEarly,
return an error for reverse compatibility.
- Add validation.Collector to simplify aggregating validation errors
from multiple sources and extracting invalid object IDs.
- Add invalid objects to the TestContext so they can be retained in
the inventory (only if already present). This primarily applies to
invalid annotations and dependencies. Objects without name or kind
should never be added to the inventory.
- Update Solver to use validation.Collector and filter invalid objects.
- Add e2e test for invalid objects.
- Update Printers to handle ValidationEvent
- Add ExternalDependencyError & InvalidAnnotationError to make it easier
to handle and introspect validation errors.
- Destroyer context added, with cancel test.
- Fix Applier cancel test not using specified timeouts.
- Added a few logs to help with debugging test failures
- Add test for applier.Run context cancel/timeout
- Add AssertEqual & AssertNotEqual to wrap testutil.Equal matcher
- Move common test utils to common_test.go
- Use yaml artifacts, instead of Unstructured
- Use apply.Options as test input
- Use UnstructuredSet as test input
- Extract Applier construction with fake inputs to newTestApplier
- Extract nil inventory to its own test to simplify test inputs
