Functions ¶

func IterateChunkEntries ¶

func IterateChunkEntries(st storage.Store, fn func(swarm.Address, bool) (bool, error)) error

func IterateLocations ¶

func IterateLocations(
	ctx context.Context,
	st storage.Store,
	locationResultC chan<- LocationResult,
)

IterateLocations iterates over entire retrieval index and plucks only sharky location.

Types ¶

type ChunkStoreWrapper ¶

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

func New ¶

func New(store storage.Store, sharky Sharky) *ChunkStoreWrapper

func (*ChunkStoreWrapper) Close ¶

func (c *ChunkStoreWrapper) Close() error

func (*ChunkStoreWrapper) Delete ¶

func (c *ChunkStoreWrapper) Delete(ctx context.Context, addr swarm.Address) error

func (*ChunkStoreWrapper) Get ¶

func (c *ChunkStoreWrapper) Get(ctx context.Context, addr swarm.Address) (swarm.Chunk, error)

func (*ChunkStoreWrapper) Has ¶

func (c *ChunkStoreWrapper) Has(_ context.Context, addr swarm.Address) (bool, error)

func (*ChunkStoreWrapper) Iterate ¶

func (c *ChunkStoreWrapper) Iterate(ctx context.Context, fn storage.IterateChunkFn) error

func (*ChunkStoreWrapper) Put ¶

func (c *ChunkStoreWrapper) Put(ctx context.Context, ch swarm.Chunk) error

type LocationResult ¶

type LocationResult struct {
	Err      error
	Location sharky.Location
}

type Sharky ¶

type Sharky interface {
	Read(context.Context, sharky.Location, []byte) error
	Write(context.Context, []byte) (sharky.Location, error)
	Release(context.Context, sharky.Location) error
}

Sharky provides an abstraction for the sharky.Store operations used in the chunkstore. This allows us to be more flexible in passing in the sharky instance to chunkstore. For eg, check the TxChunkStore implementation in this pkg.

type TxChunkStoreWrapper ¶

type TxChunkStoreWrapper struct {
	*storage.TxChunkStoreBase
	// contains filtered or unexported fields
}

func NewTxChunkStore ¶

func NewTxChunkStore(txStore storage.TxStore, csSharky Sharky) *TxChunkStoreWrapper

func (*TxChunkStoreWrapper) Commit ¶

func (cs *TxChunkStoreWrapper) Commit() error

func (*TxChunkStoreWrapper) NewTx ¶

func (cs *TxChunkStoreWrapper) NewTx(state *storage.TxState) storage.TxChunkStore

func (*TxChunkStoreWrapper) Recover ¶

func (cs *TxChunkStoreWrapper) Recover() error

Recover attempts to recover from a previous crash by reverting all uncommitted transactions.

func (*TxChunkStoreWrapper) Rollback ¶

func (cs *TxChunkStoreWrapper) Rollback() error
