Raw Blame History

C01. Locator: SRC-0008, Updates to existing resources, second paragraph Paraphrase: If a client submits an update to a resource using a resourceVersion that is no longer current, the Kubernetes API server responds with a 409 Conflict error. Assumptions:

  • The client-provided resourceVersion is intended to reflect the state of the resource the client last observed.
  • "Stale" means the resourceVersion provided by the client does not match the current resourceVersion on the server. Interpretation: This describes a specific behavior of the Kubernetes API server when handling updates with outdated resource versions. It establishes a boundary where the server rejects updates if the client's view of the resource is stale, preventing accidental overwrites of changes made by others. Counterevidence: None. Unknowns: The exact conditions under which a resourceVersion becomes "stale" (e.g., any change to the resource, or only specific types of changes). Claims needing another source: Whether this behavior is common across other API servers or is specific to Kubernetes.

C02. Locator: SRC-0008, Updates to existing resources, second paragraph Paraphrase: The Kubernetes API server uses a 409 Conflict HTTP status code to indicate that a client's proposed update is based on an outdated resourceVersion. Assumptions:

  • 409 Conflict is an HTTP status code.
  • The resourceVersion is a mechanism for optimistic concurrency control. Interpretation: The use of 409 Conflict specifically signals a concurrency issue where the client's state is out of sync with the server's, rather than a general error. Counterevidence: None. Unknowns: The specific content or structure of the error response body accompanying the 409 Conflict status. Claims needing another source: How clients are expected to handle a 409 Conflict response in this scenario (e.g., retry after fetching the latest version).
