Create creates a new blob that can be written optionally takes a size argument for performance improvements, -1 is unknown size.

func (*BadBlobs) CreateVerificationFile ¶

func (bad *BadBlobs) CreateVerificationFile(ctx context.Context, id storj.NodeID) error

CreateVerificationFile creates a file to be used for storage directory verification.

func (*BadBlobs) Delete ¶

func (bad *BadBlobs) Delete(ctx context.Context, ref blobstore.BlobRef) error

Delete deletes the blob with the namespace and key.

func (*BadBlobs) DeleteNamespace ¶

func (bad *BadBlobs) DeleteNamespace(ctx context.Context, ref []byte) (err error)

DeleteNamespace deletes blobs of specific satellite, used after successful GE only.

func (*BadBlobs) DeleteWithStorageFormat ¶

func (bad *BadBlobs) DeleteWithStorageFormat(ctx context.Context, ref blobstore.BlobRef, formatVer blobstore.FormatVersion) error

DeleteWithStorageFormat deletes the blob with the namespace, key, and format version.

func (*BadBlobs) EmptyTrash ¶

func (bad *BadBlobs) EmptyTrash(ctx context.Context, namespace []byte, trashedBefore time.Time) (int64, [][]byte, error)

EmptyTrash empties the trash.

func (*BadBlobs) FreeSpace ¶

func (bad *BadBlobs) FreeSpace(ctx context.Context) (int64, error)

FreeSpace return how much free space left for writing.

func (*BadBlobs) ListNamespaces ¶

func (bad *BadBlobs) ListNamespaces(ctx context.Context) ([][]byte, error)

ListNamespaces returns all namespaces that might be storing data.

func (*BadBlobs) Open ¶

func (bad *BadBlobs) Open(ctx context.Context, ref blobstore.BlobRef) (blobstore.BlobReader, error)

Open opens a reader with the specified namespace and key.

func (*BadBlobs) OpenWithStorageFormat ¶

func (bad *BadBlobs) OpenWithStorageFormat(ctx context.Context, ref blobstore.BlobRef, formatVer blobstore.FormatVersion) (blobstore.BlobReader, error)

OpenWithStorageFormat opens a reader for the already-located blob, avoiding the potential need to check multiple storage formats to find the blob.

func (*BadBlobs) RestoreTrash ¶

func (bad *BadBlobs) RestoreTrash(ctx context.Context, namespace []byte) ([][]byte, error)

RestoreTrash restores all files in the trash.

func (*BadBlobs) SetCheckError ¶

func (bad *BadBlobs) SetCheckError(err error)

SetCheckError configures the blob store to return a specific error for verification operations.

func (*BadBlobs) SetError ¶

func (bad *BadBlobs) SetError(err error)

SetError configures the blob store to return a specific error for all operations, except verification.

func (*BadBlobs) SpaceUsedForBlobs ¶

func (bad *BadBlobs) SpaceUsedForBlobs(ctx context.Context) (int64, error)

SpaceUsedForBlobs adds up how much is used in all namespaces.

func (*BadBlobs) SpaceUsedForBlobsInNamespace ¶

func (bad *BadBlobs) SpaceUsedForBlobsInNamespace(ctx context.Context, namespace []byte) (int64, error)

SpaceUsedForBlobsInNamespace adds up how much is used in the given namespace.

func (*BadBlobs) SpaceUsedForTrash ¶

func (bad *BadBlobs) SpaceUsedForTrash(ctx context.Context) (int64, error)

SpaceUsedForTrash adds up how much is used in all namespaces.

func (*BadBlobs) Stat ¶

func (bad *BadBlobs) Stat(ctx context.Context, ref blobstore.BlobRef) (blobstore.BlobInfo, error)

Stat looks up disk metadata on the blob file.

func (*BadBlobs) StatWithStorageFormat ¶

func (bad *BadBlobs) StatWithStorageFormat(ctx context.Context, ref blobstore.BlobRef, formatVer blobstore.FormatVersion) (blobstore.BlobInfo, error)

StatWithStorageFormat looks up disk metadata for the blob file with the given storage format version. This avoids the potential need to check multiple storage formats for the blob when the format is already known.

func (*BadBlobs) Trash ¶

func (bad *BadBlobs) Trash(ctx context.Context, ref blobstore.BlobRef) error

Trash deletes the blob with the namespace and key.

func (*BadBlobs) VerifyStorageDir ¶

func (bad *BadBlobs) VerifyStorageDir(ctx context.Context, id storj.NodeID) error

VerifyStorageDir verifies that the storage directory is correct by checking for the existence and validity of the verification file.

func (*BadBlobs) WalkNamespace ¶

func (bad *BadBlobs) WalkNamespace(ctx context.Context, namespace []byte, walkFunc func(blobstore.BlobInfo) error) error

WalkNamespace executes walkFunc for each locally stored blob in the given namespace. If walkFunc returns a non-nil error, WalkNamespace will stop iterating and return the error immediately.

type BadDB ¶

type BadDB struct {
	storagenode.DB
	Blobs ErrorBlobs
	// contains filtered or unexported fields
}

BadDB implements bad storage node DB.

func NewBadDB ¶

func NewBadDB(log *zap.Logger, db storagenode.DB) *BadDB
