OCPBUGS-105876: tolerate brief olm Available=False during upgrades

[fgiudici]

clusteroperator/olm can briefly flip to Available=False (about 1 second) during upgrades when MCO drains a node hosting catalogd pods, reported as CatalogdDeploymentCatalogdControllerManager_Deploying. This is a known, harmless blip with no real service disruption; except it the same way other operators' known transient blips are handled here.

This is a temporary tolerance. The real fix is a grace period on the Available condition, tracked in OCPBUGS-105876; once that lands this exception can be removed.

Summary by CodeRabbit

• Bug Fixes
  • Prevented a false upgrade-state failure while the olm operator is deploying its catalog controller.
  • Improved upgrade monitoring for this transitional deployment state.

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

Walkthrough

The legacy cluster version monitor adds an upgrade exception for the olm operator when it reports Available=False with reason CatalogdDeploymentCatalogdControllerManager_Deploying.

Changes

OLM upgrade monitoring

Layer / File(s)	Summary
OLM deploying condition exception pkg/monitortests/clusterversionoperator/legacycvomonitortests/operators.go	The monitor recognizes the specified OLM unavailable condition and returns the OCPBUGS-105876 issue reference.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 33950

The change is localized, but the OLM exception may tolerate an unavailable condition for up to the surrounding 10-minute interval rather than only the brief upgrade blip, potentially delaying detection of a real issue; merge is reasonable with owner awareness or a follow-up to tighten or verify the duration bound.

Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	The commit changes only one exception branch and adds no Ginkgo or JUnit test title. Existing test names remain operator/condition-based; dynamic values occur in failure output, not titles.
Test Structure And Quality	✅ Passed	The 5-line change only adds a condition branch to an existing helper; it adds no Ginkgo It block, resource setup, waits, or assertions to assess.
Microshift Test Compatibility	✅ Passed	The diff adds only an existing monitor exception in operators.go; it adds no Ginkgo e2e test (It, Describe, Context, or When), so this check is not applicable.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR changes only an existing operator-state exception in operators.go; it adds no Ginkgo e2e tests or multi-node assumptions.
Topology-Aware Scheduling Compatibility	✅ Passed	The diff only adds an OLM Available=False exception in a monitoring test; it adds no deployment, controller, manifest, or scheduling constraint.
Ote Binary Stdout Contract	✅ Passed	The HEAD diff adds only condition matching and a Jira URL return in testUpgradeOperatorStateTransitions; it adds no stdout, logging, or process-level setup writes.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The diff adds only an OLM condition exception in operators.go. It adds no Ginkgo test and no IPv4 or external-connectivity behavior.
No-Weak-Crypto	✅ Passed	The commit adds only an OLM condition exception and Jira URL; no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom crypto, or secret comparison was introduced.
Container-Privileges	✅ Passed	The commit changes only Go logic. It adds no container/Kubernetes manifest and no privileged, host namespace, SYS_ADMIN, root, or allowPrivilegeEscalation setting.
No-Sensitive-Data-In-Logs	✅ Passed	The 5-line change only matches an OLM condition and returns a static Jira URL; it adds no logging or sensitive data, and existing JUnit output handling is unchanged.

Add regression coverage for the exception contract.

Add tests for the exact positive case and for non-OLM operators, different condition types or statuses, different reasons, and intervals outside the intended transient bound. The supplied graph context identifies pkg/monitortests/clusterversionoperator/legacycvomonitortests/operators_test.go as the adjacent test file.

@hongkailiu can you review this exception?

[hongkailiu]

My reply is in the bug.
It would be nice if the olm team can take a look.

[dgoodwin]

/approve

I would like Hongkai or someone near OLM to lgtm.

Rationale here, it looked to me like this exception happened lots previously, but it was ignored if the upgrade failed and treated as a flake. We now fail this test way less often, and the upgrade fails way less often, but this blip continues in both cases.
