Functions

func Commit

func Commit(ctx context.Context, client pb.ArtifactStagingServiceClient, artifacts []*pb.ArtifactMetadata) (string, error)

Commit commits a manifest with the given staged artifacts. It returns the staging token, if successful.

func Materialize

func Materialize(ctx context.Context, endpoint string, dest string) ([]*pb.ArtifactMetadata, error)

Materialize is a convenience helper for ensuring that all artifacts are present and uncorrupted. It interprets each artifact name as a relative path under the dest directory. It does not retrieve valid artifacts already present.

func MultiRetrieve

func MultiRetrieve(ctx context.Context, client pb.ArtifactRetrievalServiceClient, cpus int, list []*pb.ArtifactMetadata, dest string) error

MultiRetrieve retrieves multiple artifacts concurrently, using at most 'cpus' goroutines. It retries each artifact a few times. Convenience wrapper.

func MultiStage

func MultiStage(ctx context.Context, client pb.ArtifactStagingServiceClient, cpus int, list []KeyedFile) ([]*pb.ArtifactMetadata, error)

MultiStage stages a set of local files with the given keys. It returns the full artifact metadate. It retries each artifact a few times. Convenience wrapper.

func Retrieve

Retrieve checks whether the given artifact is already successfully retrieved. If not, it retrieves into the dest directory. It overwrites any previous retrieval attempt and may leave a corrupt/partial local file on failure.

func Stage

func Stage(ctx context.Context, client pb.ArtifactStagingServiceClient, key, filename string) (*pb.ArtifactMetadata, error)

Stage stages a local file as an artifact with the given key. It computes the MD5 and returns the full artifact metadata.

func StageDir

StageDir stages a local directory with relative path keys. Convenience wrapper.

Types

type KeyedFile

type KeyedFile struct {
	Key, Filename string
}

KeyedFile is a key and filename pair.
