Functions ¶

func ExtractBlobIDFromFilename ¶

func ExtractBlobIDFromFilename(filename string) string

extractBlobIDFromFilename extracts the blob ID from a cache filename Cache files can have formats like: - <blobID> - <blobID>.blob.data - <blobID>.chunk_map - <blobID>.blob.meta - <blobID>.image.disk - <blobID>.layer.disk

Types ¶

type Manager ¶

type Manager struct {
	// contains filtered or unexported fields
}

Disk cache manager for fusedev.

func NewManager ¶

func NewManager(opt Opt) (*Manager, error)

func (*Manager) CacheDir ¶

func (m *Manager) CacheDir() string

func (*Manager) CacheUsage ¶

func (m *Manager) CacheUsage(ctx context.Context, blobID string) (snapshots.Usage, error)

Report each blob disk usage TODO: For fscache cache files, the cache files are managed by nydusd and Linux kernel We don't know how it manages cache files. A method to address this is to query nydusd. So we can't report cache usage in the case of fscache now

func (*Manager) RemoveBlobCache ¶

func (m *Manager) RemoveBlobCache(blobID string) error

type Opt ¶

type Opt struct {
	Disabled bool
	CacheDir string
	Period   time.Duration
	Database *store.Database
}
