OCPBUGS-94252: Implement degraded-mode NodePool informer for pre-existing invalid durations - #9441
OCPBUGS-94252: Implement degraded-mode NodePool informer for pre-existing invalid durations#9441vismishr wants to merge 16 commits into
Conversation
…ach timeouts Add XValidation CEL rules to nodeDrainTimeout and nodeVolumeDetachTimeout fields on NodePoolSpec to reject invalid duration strings at admission time. Previously, malformed values like "1" (no unit suffix) passed CRD validation, got stored in etcd, and crashed the cluster-wide NodePool informer on deserialization. Follows the HTTPKeepAliveTimeout precedent from openshift/api for the CEL regex pattern matching Go duration syntax.
…ection Update NodePool nodeDrainTimeout and nodeVolumeDetachTimeout CEL validation to use duration() function for overflow detection and accept leading-dot decimals like .5s. Follows the HTTPKeepAliveTimeout two-rule pattern: regex for format + guarded duration() for range check. Add envtest coverage for .5s, us suffix, and overflow edge cases.
Add startup detection and degraded-mode skip for pre-existing NodePools with invalid duration fields (OCPBUGS-94252 defense-in-depth). New file: hypershift-operator/controllers/nodepool/degraded_lister.go - ScanAndIdentifyBadNodePools(): one-time startup scan via dynamic client - NewDegradedModeInformerFactory(): custom informer factory that wraps NodePool ListerWatcher to filter out bad objects - degradedNodePoolListerWatcher: implements toolscache.ListerWatcher with filtering on List() calls Modified: hypershift-operator/main.go - Call ScanAndIdentifyBadNodePools() before manager creation - Pass degraded-mode factory to manager cache options if bad NodePools found - Log ERROR messages identifying each bad NodePool with exact field, value, and kubectl patch command to fix Behavior: - On startup: scan all NodePools for invalid duration fields - If bad data found: skip those NodePools from cache (O(1) filter per LIST) - Operator continues normally on valid NodePools (no downtime) - ERROR logs persist until customer manually fixes the bad NodePool(s) - Next LIST/WATCH automatically picks up fixed objects (no restart needed) Companion to OCPBUGS-94251 (CEL validation prevents new bad values).

Filter malformed objects before typed LIST decoding.
delegate.List(opts) decodes the complete response as NodePoolList before this wrapper can filter it. A malformed persisted metav1.Duration can fail that decoding and prevent valid NodePools from entering the informer cache. Use an unstructured LIST path, remove invalid objects, and convert the remaining objects before returning them.

Official Go documentation for time.ParseDuration optional leading sign and examples of parsing negative and positive durations
💡 Result:
The official Go documentation for time.ParseDuration states that it parses a duration string defined as a possibly signed sequence of decimal numbers, where each number has an optional fraction and a unit suffix [1][2]. Leading Sign The leading sign is optional. A string can start with either a plus (+) or minus (-) sign to indicate the sign of the duration [3][4]. If no sign is provided, the duration is treated as positive. Examples According to the Go documentation and source examples, common parsing patterns include [1][2][5]: Positive Durations: "10h" (10 hours) "2h45m" (2 hours, 45 minutes) "1h10m10s" (1 hour, 10 minutes, 10 seconds) Negative Durations: "-1.5h" (negative 1 hour, 30 minutes) Valid units include "ns", "us" (or "µs"), "ms", "s", "m", and "h" [1][2]. The package also accepts "us" as a common, albeit technically incorrect, prefix for microseconds [1][6].

Apply the API’s unsigned, non-negative duration validation during the startup scan. time.ParseDuration accepts -1s and +1s, but the scan records only parse errors. Therefore, signed values are not added to badFields, and the NodePool can remain eligible for reconciliation.

Pass the lifecycle context to the startup scan.
run calls createManager synchronously, but createManager replaces its context with context.Background() before ScanAndIdentifyBadNodePools performs the API list. A stalled request can therefore block manager startup and ignore shutdown cancellation. Pass the lifecycle context into createManager and apply a scan timeout.

When a NodePool is fixed, revalidate it during LIST and remove from badKeys so it appears in subsequent LISTs and WATCHes. Previously fixed NodePools would disappear again on the next relist because badKeys was never updated. Addresses CodeRabbit finding: recovered NodePools should be available across relists, not cached as invalid indefinitely.

Assert the non-NodePool factory path.
Line 69 makes no assertion when tt.want is false. The test does not prove that a non-NodePool uses the standard informer. An implementation that wraps every object can pass this test.
Exercise observable LIST behavior that differs between the standard and degraded lister watcher for both object types.

Use malformed duration fixtures for invalid NodePool cases.
Both sites supply valid values. A zero metav1.Duration is a recovered NodePool and must be re-included during LIST. A nil timeout is also valid. These tests can pass when malformed duration filtering regresses.

Verify that Watch delegates and returns its result.
The test only checks the error. A Watch implementation that returns nil, nil without calling delegate.Watch passes this test.
Return a non-nil watch from watchFunc. Track that watchFunc was called. Assert that wrapper.Watch returns that watch.

Codespell was flagging 'wantIn' as a typo (suggesting 'wanting', 'want in', or 'wanton'). Rename to 'shouldInclude' which is clearer and passes codespell.

The cache import was needed for the test that checks the wrapped informer type. Use the same alias as the main file (toolscache) to avoid conflicts.

Summary
Implement degraded-mode skip for pre-existing NodePools with invalid duration fields (OCPBUGS-94252 defense-in-depth).
When the operator starts, it scans all NodePools for malformed
nodeDrainTimeoutornodeVolumeDetachTimeoutvalues (ones that failtime.ParseDuration). Bad NodePools are skipped from the informer cache, allowing the operator to remain operational on valid NodePools while the customer manually fixes the bad data.Companion to OCPBUGS-94251 (PR #9117): that PR adds CEL validation to prevent new bad values; this PR handles pre-existing bad data from before the validation fix was deployed.
