Types

type BlobManipulator

type BlobManipulator struct {
	KopiaCommandRunner *kopiarunner.KopiaSnapshotter
	DirCreater         *snapmeta.KopiaSnapshotter

	DataRepoPath       string
	CanRunMaintenance  bool
	PathToTakeSnapshot string
	// contains filtered or unexported fields
}

BlobManipulator provides a way to run a kopia command.

func NewBlobManipulator

func NewBlobManipulator(baseDirPath, dataRepoPath string) (*BlobManipulator, error)

NewBlobManipulator instantiates a new BlobManipulator and returns its pointer.

func (*BlobManipulator) ConnectOrCreateRepo

func (bm *BlobManipulator) ConnectOrCreateRepo(dataRepoPath string) error

ConnectOrCreateRepo connects to an existing repository if possible or creates a new one.

func (*BlobManipulator) DeleteBlob

func (bm *BlobManipulator) DeleteBlob(blobID string) error

DeleteBlob deletes the provided blob or a random blob, in kopia repo.

func (*BlobManipulator) DeleteSnapshot

func (bm *BlobManipulator) DeleteSnapshot(snapshotID string) (string, error)

DeleteSnapshot deletes provided snapshot.

func (*BlobManipulator) GenerateRandomFiles

func (bm *BlobManipulator) GenerateRandomFiles(fileSize, numFiles int) error

GenerateRandomFiles connects or creates a Kopia repository that writes random data in source directory. Tests can later create snapshots from the source directory.

func (*BlobManipulator) RestoreGivenOrRandomSnapshot

func (bm *BlobManipulator) RestoreGivenOrRandomSnapshot(snapID, restoreDir string) (string, error)

RestoreGivenOrRandomSnapshot restores a given or a random snapshot from kopia repository into the provided target directory.

func (*BlobManipulator) RunMaintenance

func (bm *BlobManipulator) RunMaintenance() (string, error)

RunMaintenance runs repository maintenance.

func (*BlobManipulator) SetUpSystemUnderTest

func (bm *BlobManipulator) SetUpSystemUnderTest() error

SetUpSystemUnderTest connects or creates a kopia repo, writes random data in source directory, creates snapshots of the source directory.

func (*BlobManipulator) SetUpSystemWithOneSnapshot

func (bm *BlobManipulator) SetUpSystemWithOneSnapshot() (string, error)

SetUpSystemWithOneSnapshot connects or creates a kopia repo, writes random data in source directory, creates snapshots of the source directory.

func (*BlobManipulator) SnapshotFixInvalidFiles

func (bm *BlobManipulator) SnapshotFixInvalidFiles(flags string) (string, error)

SnapshotFixInvalidFiles runs snapshot fix invalid-files command with the provided flags.

func (*BlobManipulator) SnapshotFixRemoveFilesByBlobID

func (bm *BlobManipulator) SnapshotFixRemoveFilesByBlobID(blobID string) (string, error)

SnapshotFixRemoveFilesByBlobID runs snapshot fix remove-files command with a provided blob id.

func (*BlobManipulator) SnapshotFixRemoveFilesByFilename

func (bm *BlobManipulator) SnapshotFixRemoveFilesByFilename(filename string) (string, error)

SnapshotFixRemoveFilesByFilename runs snapshot fix remove-files command with a provided file name.

func (*BlobManipulator) TakeSnapshot

func (bm *BlobManipulator) TakeSnapshot(dir string) (snapID, stdout string, err error)
