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Paraphrase: If a client submits an update to a resource using a `resourceVersion` that is no longer current, the Kubernetes API server responds with a `409 Conflict` error.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Interpretation: This describes a specific behavior of the Kubernetes API server when handling updates with outdated resource versions.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.

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Kubernetes API server uses a `409 Conflict` HTTP status code to indicate that a client's proposed update is based on an outdated `resourceVersion`.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). |
