They contain some nice-to-have improvements (for example, better printing of errors with gomega/format.Object) but nothing that is critical right now. "go mod tidy" was run manually in staging/src/k8s.io/kms/internal/plugins/mock (https://github.com/kubernetes/kubernetes/pull/116613 not merged yet).

/*

SpecContext includes a reference to `suite` and embeds itself in itself as a "GINKGO_SPEC_CONTEXT" value. This allows users to create child Contexts without having down-stream consumers (e.g. Gomega) lose access to the SpecContext and its methods. This allows us to build extensions on top of Ginkgo that simply take an all-encompassing context.
|
|
|
|
Note that while SpecContext is used to enforce deadlines by Ginkgo it is not configured as a context.WithDeadline. Instead, Ginkgo owns responsibility for cancelling the context when the deadline elapses.
|
|
|
|
This is because Ginkgo needs finer control over when the context is canceled. Specifically, Ginkgo needs to generate a ProgressReport before it cancels the context to ensure progress is captured where the spec is currently running. The only way to avoid a race here is to manually control the cancellation.
