Types ¶

type Cache ¶

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

Cache is one store's blob directory. It is safe for concurrent use by several processes: entries are written next to their final name and renamed into place.

func Open ¶

func Open(dir, storeID string, limit int64) (*Cache, error)

Open returns the cache of one store under dir. limit caps the cache in bytes when Sweep runs; 0 leaves it unbounded.

func (*Cache) Dir ¶

func (c *Cache) Dir() string

Dir is the cache directory.

func (*Cache) Drop ¶

func (c *Cache) Drop(ref *proto.Ref)

Drop removes the entry for ref.

func (*Cache) Get ¶

func (c *Cache) Get(ref *proto.Ref) (*proto.Object, bool)

Get returns the cached object for ref after checking that it still hashes to it. A corrupt entry is removed.

func (*Cache) Put ¶

func (c *Cache) Put(ref *proto.Ref, obj *proto.Object) error

Put stores the object under ref unless it is already there.

func (*Cache) Sweep ¶

func (c *Cache) Sweep() (int, error)

Sweep removes the least recently used entries until the cache fits its limit and returns how many it removed.
