Functions

func DefaultProofRuntime 

func DefaultProofRuntime() (prt *merkle.ProofRuntime)

XXX: This should be managed by the rootMultiStore which may want to register more proof ops?

func GetLatestVersion 

func GetLatestVersion(db dbm.DB) int64

func RequireProof 

func RequireProof(subpath string) bool

RequireProof returns whether proof is required for the subpath.

Types

type Store 

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

Store is composed of many CommitStores. Name contrasts with cacheMultiStore which is used for branching other MultiStores. It implements the CommitMultiStore interface.

func NewStore 

func NewStore(db dbm.DB, logger log.Logger) *Store

NewStore returns a reference to a new Store object with the provided DB. The store will be created with a PruneNothing pruning strategy by default. After a store is created, KVStores must be mounted and finally LoadLatestVersion or LoadVersion must be called.

func (*Store) AddListeners 

func (rs *Store) AddListeners(key types.StoreKey, listeners []types.WriteListener)

AddListeners adds listeners for a specific KVStore

func (*Store) CacheMultiStore 

func (rs *Store) CacheMultiStore() types.CacheMultiStore

CacheMultiStore creates ephemeral branch of the multi-store and returns a CacheMultiStore. It implements the MultiStore interface.

func (*Store) CacheMultiStoreWithVersion 

func (rs *Store) CacheMultiStoreWithVersion(version int64) (types.CacheMultiStore, error)

CacheMultiStoreWithVersion is analogous to CacheMultiStore except that it attempts to load stores at a given version (height). An error is returned if any store cannot be loaded. This should only be used for querying and iterating at past heights.

func (*Store) CacheWrap 

func (rs *Store) CacheWrap() types.CacheWrap

CacheWrap implements CacheWrapper/Store/CommitStore.

func (*Store) CacheWrapWithTrace 

func (rs *Store) CacheWrapWithTrace(_ io.Writer, _ types.TraceContext) types.CacheWrap

CacheWrapWithTrace implements the CacheWrapper interface.

func (*Store) Commit 

func (rs *Store) Commit() types.CommitID

Commit implements Committer/CommitStore.

func (*Store) GetCommitInfo 

func (rs *Store) GetCommitInfo(ver int64) (*types.CommitInfo, error)

GetCommitInfo attempts to retrieve CommitInfo for a given version/height. It will return an error if no CommitInfo exists, we fail to unmarshal the record or if we cannot retrieve the object from the DB.

func (*Store) GetCommitKVStore 

func (rs *Store) GetCommitKVStore(key types.StoreKey) types.CommitKVStore

GetCommitKVStore returns a mounted CommitKVStore for a given StoreKey. If the store is wrapped in an inter-block cache, it will be unwrapped before returning.

func (*Store) GetCommitStore 

func (rs *Store) GetCommitStore(key types.StoreKey) types.CommitStore

GetCommitStore returns a mounted CommitStore for a given StoreKey. If the store is wrapped in an inter-block cache, it will be unwrapped before returning.

func (*Store) GetKVStore 

func (rs *Store) GetKVStore(key types.StoreKey) types.KVStore

GetKVStore returns a mounted KVStore for a given StoreKey. If tracing is enabled on the KVStore, a wrapped TraceKVStore will be returned with the root store's tracer, otherwise, the original KVStore will be returned.

NOTE: The returned KVStore may be wrapped in an inter-block cache if it is set on the root store.

func (*Store) GetPruning 

func (rs *Store) GetPruning() pruningtypes.PruningOptions

GetPruning fetches the pruning strategy from the root store.

func (*Store) GetStore 

func (rs *Store) GetStore(key types.StoreKey) types.Store

GetStore returns a mounted Store for a given StoreKey. If the StoreKey does not exist, it will panic. If the Store is wrapped in an inter-block cache, it will be unwrapped prior to being returned.

TODO: This isn't used directly upstream. Consider returning the Store as-is instead of unwrapping.

func (*Store) GetStoreByName 

func (rs *Store) GetStoreByName(name string) types.Store

getStoreByName performs a lookup of a StoreKey given a store name typically provided in a path. The StoreKey is then used to perform a lookup and return a Store. If the Store is wrapped in an inter-block cache, it will be unwrapped prior to being returned. If the StoreKey does not exist, nil is returned.

func (*Store) GetStoreType 

func (rs *Store) GetStoreType() types.StoreType

GetStoreType implements Store.

func (*Store) LastCommitID 

func (rs *Store) LastCommitID() types.CommitID

LastCommitID implements Committer/CommitStore.

func (*Store) LatestVersion 

func (rs *Store) LatestVersion() int64

LatestVersion returns the latest version in the store

func (*Store) ListeningEnabled 

func (rs *Store) ListeningEnabled(key types.StoreKey) bool

ListeningEnabled returns if listening is enabled for a specific KVStore

func (*Store) LoadLatestVersion 

func (rs *Store) LoadLatestVersion() error

LoadLatestVersion implements CommitMultiStore.

func (*Store) LoadLatestVersionAndUpgrade 

func (rs *Store) LoadLatestVersionAndUpgrade(upgrades *types.StoreUpgrades) error

LoadLatestVersionAndUpgrade implements CommitMultiStore

func (*Store) LoadVersion 

func (rs *Store) LoadVersion(ver int64) error

LoadVersion implements CommitMultiStore.

func (*Store) LoadVersionAndUpgrade 

func (rs *Store) LoadVersionAndUpgrade(ver int64, upgrades *types.StoreUpgrades) error

LoadVersionAndUpgrade allows us to rename substores while loading an older version

func (*Store) MountStoreWithDB 

func (rs *Store) MountStoreWithDB(key types.StoreKey, typ types.StoreType, db dbm.DB)

MountStoreWithDB implements CommitMultiStore.

func (*Store) PruneSnapshotHeight 

func (rs *Store) PruneSnapshotHeight(height int64)

PruneSnapshotHeight prunes the given height according to the prune strategy. If PruneNothing, this is a no-op. If other strategy, this height is persisted until it is less than <current height> - KeepRecent and <current height> % Interval == 0

func (*Store) PruneStores 

func (rs *Store) PruneStores(clearPruningManager bool, pruningHeights []int64) (err error)

PruneStores prunes the specific heights of the multi store. If clearPruningManager is true, the pruning manager will return the pruning heights, and they are appended to the pruningHeights to be pruned.

func (*Store) Query 

func (rs *Store) Query(req abci.RequestQuery) abci.ResponseQuery

Query calls substore.Query with the same `req` where `req.Path` is modified to remove the substore prefix. Ie. `req.Path` here is `/<substore>/<path>`, and trimmed to `/<path>` for the substore. TODO: add proof for `multistore -> substore`.

func (*Store) Restore 

func (rs *Store) Restore(
	height uint64, format uint32, protoReader protoio.Reader,
) (snapshottypes.SnapshotItem, error)

Restore implements snapshottypes.Snapshotter. returns next snapshot item and error.

SetCommitHeader sets the commit block header of the store.

func (*Store) SetIAVLCacheSize 

func (rs *Store) SetIAVLCacheSize(cacheSize int)

func (*Store) SetIAVLDisableFastNode 

func (rs *Store) SetIAVLDisableFastNode(disableFastNode bool)

func (*Store) SetInitialVersion 

func (rs *Store) SetInitialVersion(version int64) error

SetInitialVersion sets the initial version of the IAVL tree. It is used when starting a new chain at an arbitrary height.

func (*Store) SetInterBlockCache 

func (rs *Store) SetInterBlockCache(c types.MultiStorePersistentCache)

SetInterBlockCache sets the Store's internal inter-block (persistent) cache. When this is defined, all CommitKVStores will be wrapped with their respective inter-block cache.

func (*Store) SetLazyLoading 

func (rs *Store) SetLazyLoading(lazyLoading bool)

SetLazyLoading sets if the iavl store should be loaded lazily or not

func (*Store) SetPruning 

func (rs *Store) SetPruning(pruningOpts pruningtypes.PruningOptions)

SetPruning sets the pruning strategy on the root store and all the sub-stores. Note, calling SetPruning on the root store prior to LoadVersion or LoadLatestVersion performs a no-op as the stores aren't mounted yet.

func (*Store) SetSnapshotInterval 

func (rs *Store) SetSnapshotInterval(snapshotInterval uint64)

SetSnapshotInterval sets the interval at which the snapshots are taken. It is used by the store to determine which heights to retain until after the snapshot is complete.

func (*Store) SetTracer 

func (rs *Store) SetTracer(w io.Writer) types.MultiStore

SetTracer sets the tracer for the MultiStore that the underlying stores will utilize to trace operations. A MultiStore is returned.

func (*Store) SetTracingContext 

func (rs *Store) SetTracingContext(tc types.TraceContext) types.MultiStore

SetTracingContext updates the tracing context for the MultiStore by merging the given context with the existing context by key. Any existing keys will be overwritten. It is implied that the caller should update the context when necessary between tracing operations. It returns a modified MultiStore.

func (*Store) Snapshot 

func (rs *Store) Snapshot(height uint64, protoWriter protoio.Writer) error

Snapshot implements snapshottypes.Snapshotter. The snapshot output for a given format must be identical across nodes such that chunks from different sources fit together. If the output for a given format changes (at the byte level), the snapshot format must be bumped - see TestMultistoreSnapshot_Checksum test.
