RFE-8872: warn and confirm before deleting PV/PVC - #2376
Conversation
Prompt in a terminal before oc delete removes a persistent volume or claim so accidental deletes are less likely to cause data loss or workload downtime. Non-interactive sessions are unchanged. Co-authored-by: Cursor <cursoragent@cursor.com>

WalkthroughThe pull request adds an OpenShift ChangesStorage delete confirmation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The PR adds confirmation before PV/PVC deletion, but the current implementation can miss valid local manifests and can proceed with deletion when the warning cannot be displayed. These paths may allow destructive deletion without the intended confirmation, so the PR is not merge-ready until detection and fail-closed error handling are corrected.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Parse complete manifests before deciding whether to prompt.
The bounded raw-text scan can miss valid PV/PVC documents, including JSON with escaped kind values and documents that occur after the first 1 MiB. In those cases, oc delete -f ... can invoke deletion without the required confirmation. Decode all YAML/JSON documents, inspect decoded kind values including list items, and add regressions for escaped JSON and a PV/PVC document after 1 MiB.

Use the Complete, Validate, and Run lifecycle.
NewCmdDelete resolves flags and starts confirmation directly in the Cobra Run callback. Move this flow to methods on storageDeleteConfirmOptions.
Complete should read command flags. Validate should check invariants without prompting. Run should perform confirmation and delegate to originalRun.
As per coding guidelines, “All commands implement a three-phase lifecycle on an Options struct.”

Fail closed when the prompt cannot be written.
Line 210 ignores a prompt write error. If streams.ErrOut fails and the reader supplies y, confirmStorageDelete returns true and Line 63 executes deletion without delivering the warning.
Return the prompt write error with context, or treat it as a declined confirmation. Also handle the cancellation-message write error at Line 58. Add a failing-writer test that verifies the wrapped delete does not run.

Handle the file close error.
Line 200 discards the result of f.Close(). This fails errcheck and violates the required error-handling policy.
Close the file explicitly after reading it, and handle the error before returning the detection result.
