Storage layer

Package Layout

The interface, various concrete implementations, and any associated components live here. Interfaces and types are defined at the top level package.

Currently, there are two usable storage implementation for logs:

The MySQL / MariaDB implementation includes support for Maps. This has not yet been implemented by Cloud Spanner. There may be other storage implementations available from third parties.

These implementations are under development and are not yet ready for use.

These implementations are for test purposes only and should not be used by real applications:

  • In-memory Storage, in the memory package.

Notes and Caveats

The design is such that both LogStorage and MapStorage models reuse a shared TreeStorage model which can store arbitrary nodes in a tree.

Anyone poking around in here should be aware that there are some subtle wrinkles introduced by the fact that Log trees grow upwards (i.e. the Log considers nodes at level 0 to be the leaves), and in contrast the Map considers the leaves to be at level 255 (and the root at 0), this is based on the HStar2 algorithm.

TreeStorage

Nodes

Nodes within the tree are each given a unique NodeID (see storage/types.go), this ID can be thought of as the binary path (0 for left, 1 for right) from the root of the tree down to the node in question (or, equivalently, as the binary representation of the node's horizonal index into the tree layer at the depth of the node.)

TODO(al): pictures!

Subtrees

The TreeStorage model does not, in fact, store all the internal nodes of the tree; it divides the tree into subtrees of depth 8 and stores the data for each subtree as a single unit. Within these subtrees, only the (subtree-relative) "leaf" nodes are actually written to disk, the internal structure of the subtrees is re-calculated when the subtree is read from disk.

Doing this compaction saves a considerable amout of on-disk space, and at least for the MySQL storage implementation, results in a ~20% speed increase.

History

Updates to the tree storage are performed in a batched fashion (i.e. some unit of update which provides a self-consistent view of the tree - e.g.:

  • n append leaf operations along with internal node updates for the LogStorage, and tagged with their sequence number.
  • n set value operations along with internal node updates for the MapStorage.

These batched updates are termed treeRevisions, and nodes updated within each revision are tagged with a monotonically incrementing sequence number.

In this fashion, the storage model records all historical revisions of the tree.

To perform lookups at a particular treeRevision, the TreeStorage simply requests nodes from disk which are associated with the given NodeID and whose treeRevsions are <= the desired revision.

Currently there's no mechanism to safely garbage collect obsolete nodes so storage grows without bound. This will be addressed at some point in the future for Map trees. Log trees don't need garbage collection as they're required to preserve a full history.

Updates to the tree

The current treeRevision is defined to be the one referenced by the latest Signed [Map|Log] Head (if there is no SignedHead, then the current treeRevision is -1.)

Updates to the tree are performed in the future (i.e. at currentTreeRevision + 1), and, to allow for reasonable performance, are not required to be atomic (i.e. a tree update may partially fail), however for this to work, higher layers using the storage layer must guarantee that failed tree updates are later re-tried with either precisely the same set of node chages, or a superset there-of, in order to ensure integrity of the tree.

We intend to enforce this contract within the treeStorage layer at some point in the future.

LogStorage

TODO(al): flesh this out

LogStorage builds upon TreeStorage and additionally provides a means of storing log leaves, and SignedTreeHeads, and an API for sequencing new leaves into the tree.

MapStorage

TODO(al): flesh this out

MapStorage builds upon TreeStorage and additionally provides a means of storing map values, and SignedMapHeads.

	// retry with a new transaction, and f MUST NOT keep state across calls.
	ReadWriteTransaction(ctx context.Context, tree *trillian.Tree, f LogTXFunc) error

	// QueueLeaves enqueues leaves for later integration into the tree.
	// If error is nil, the returned slice of leaves will be the same size as the
	// input, and each entry will hold a passed-in leaf struct and a Status
	// representing the outcome for that particular leaf:
	//  * a status of OK indicates that the leaf was successfully queued.
	//  * a status of AlreadyExists indicates that the leaf was a duplicate, in this case
	//    the returned leaf data is that of the original.
	// Other status values may be returned in error cases.
	//
	// Duplicates are only reported if the underlying tree does not permit duplicates, and are
	// considered duplicate if their leaf.LeafIdentityHash matches.
	QueueLeaves(ctx context.Context, tree *trillian.Tree, leaves []*trillian.LogLeaf, queueTimestamp time.Time) ([]*trillian.QueuedLogLeaf, error)

	// AddSequencedLeaves stores the `leaves` and associates them with the log
	// positions according to their `LeafIndex` field. The indices must be
	// contiguous.
	//
	// If error is nil, the returned slice is the same size as the input, entries
	// correspond to the `leaves` in the same order. Each entry describes the
	// result of adding the corresponding leaf.
	//
	// Possible `QueuedLogLeaf.status` values with their semantics:
	//  - OK: The leaf has been successfully stored.
	//  - AlreadyExists: The storage already contains an identical leaf at the
	//    specified `LeafIndex`. That leaf is returned in `QueuedLogLeaf.leaf`.
	//  - FailedPrecondition: There is another leaf with the same `LeafIndex`,
	//    but a different value. That leaf is returned in `QueuedLogLeaf.leaf`.
	//  - OutOfRange: The leaf can not be stored at the specified `LeafIndex`.
	//    For example, the storage might not support non-sequential writes.
	//  - Internal, etc: A storage-specific error.
	//
	// TODO(pavelkalinnikov): Make returning the resulting/conflicting leaves
	// optional. Channel these options to the top-level Log API.
	// TODO(pavelkalinnikov): Not checking values of the occupied indices might
	// be a good optimization. Could also be optional.
	AddSequencedLeaves(ctx context.Context, tree *trillian.Tree, leaves []*trillian.LogLeaf, timestamp time.Time) ([]*trillian.QueuedLogLeaf, error)

	// DequeueLeaves returns between [0, limit] leaves to be integrated to the
	// tree.
	//
	// For LOG trees:
	// - The leaves are taken from the queue.
	// - If the Tx is rolled back, they become available for dequeueing again.
	//
	// For PREORDERED_LOG trees:
	// - The leaves are taken from the head of as yet un-integrated part of the
	//   sequenced entries, immediately following the current SignedLogRoot tree
	//   size.
	// - The operation is a no-op with regards to the sequenced entries.
	//
	// Leaves queued more recently than the cutoff time will not be returned.
	// This allows for guard intervals to be configured, and (in case of
	// PREORDERED_LOG trees) avoiding contention between log signer and writers
	// appending new entries.
	//
	// This method is not required to return fully populated LogLeaf structures,
	// but it *must* include MerkleLeafHash, QueueTimestamp, and LeafIndex (for
	// PREORDERED_LOG trees). Storage implementations might apply optimizations
	// employing this property. Consult the call sites of this method to be sure.
	DequeueLeaves(ctx context.Context, limit int, cutoff time.Time) ([]*trillian.LogLeaf, error)

	// UpdateSequencedLeaves associates the leaves with the sequence numbers
	// assigned to them.
	UpdateSequencedLeaves(ctx context.Context, leaves []*trillian.LogLeaf) error
}

LogTreeTX is the transactional interface for reading/updating a Log. It extends the basic TreeTX interface with Log specific methods.

	ReadOnlyMapStorage

	// ReadWriteTransaction starts a RW transaction on the underlying storage, and
	// calls f with it.

	// TODO(mhutchinson): Remove the keyHash parameter or document why it is redundantly passed in
	// (it is also inside the MapLeaf)
	Set(ctx context.Context, keyHash []byte, value *trillian.MapLeaf) error

	// SetTiles stores the given tiles at the current write revision.
	SetTiles(ctx context.Context, tiles []smt.Tile) error
}

MapTreeTX is the transactional interface for reading/modifying a Map. It extends the basic TreeTX interface with Map specific methods.

	// Rollback aborts any performed operations, or returns an error.
	// See Close() for a way to automatically manage transactions.
	Rollback() error

	// IsClosed returns true if the transaction is closed.
	// A transaction is closed when either Commit() or Rollback() are
	// called.
	IsClosed() bool

	// Close rolls back the transaction if it's not yet closed.
	// It's advisable to call "defer tx.Close()" after the creation of
	// transaction to ensure that it's always rolled back if not explicitly
	// committed.
	Close() error
}

ReadOnlyAdminTX is a transaction capable only of read operations in the AdminStorage.

type ReadOnlyLogStorage

	// GetLeavesByRange returns leaf data for a range of indexes. The returned
	// slice is a contiguous prefix of leaves in [start, start+count) ordered by
	// LeafIndex. It will be shorter than `count` if the requested range has
	// missing entries (e.g., it extends beyond the size of a LOG tree), or
	// `count` is too big to handle in one go.
	// For PREORDERED_LOG trees, *must* return leaves beyond the tree size if
	// they are stored, in order to allow integrating them into the tree.
	GetLeavesByRange(ctx context.Context, start, count int64) ([]*trillian.LogLeaf, error)
	// GetLeavesByHash looks up sequenced leaf metadata and data by their Merkle leaf hash. If the
	// tree permits duplicate leaves callers must be prepared to handle multiple results with the
	// same hash but different sequence numbers. If orderBySequence is true then the returned data
	// will be in ascending sequence number order.
	GetLeavesByHash(ctx context.Context, leafHashes [][]byte, orderBySequence bool) ([]*trillian.LogLeaf, error)
	// LatestSignedLogRoot returns the most recent SignedLogRoot, if any.

	// LatestSignedMapRoot returns the most recently created SignedMapRoot.
	LatestSignedMapRoot(ctx context.Context) (*trillian.SignedMapRoot, error)

	// Get retrieves the values associated with the keyHashes, if any, at the
	// specified revision.
	// Setting revision to -1 will fetch the latest revision.
	// The returned array of MapLeaves will only contain entries for which values
	// exist.  i.e. requesting a set of unknown keys would result in a
	// zero-length array being returned.
	Get(ctx context.Context, revision int64, keyHashes [][]byte) ([]*trillian.MapLeaf, error)

	// GetTiles reads the Merkle tree tiles with the given root IDs at the given
	// revision. A tile is empty if it is missing from the returned slice.
	GetTiles(ctx context.Context, rev int64, ids []tree.NodeID2) ([]smt.Tile, error)
}

	// Commit attempts to commit any reads performed under this transaction.
	Commit(context.Context) error

	// Rollback aborts this transaction.
	Rollback() error

	// Close attempts to Rollback the TX if it's open, it's a noop otherwise.
	Close() error

	// IsOpen indicates if this transaction is open. An open transaction is one for which
	// Commit() or Rollback() has never been called. Implementations must do all clean up
	// in these methods so transactions are assumed closed regardless of the reported success.
	IsOpen() bool
}

ReadOnlyTreeTX represents a read-only transaction on a TreeStorage. A ReadOnlyTreeTX can only modify the tree specified in its creation.

type Row added in v1.3.0

type TreeTX 

type TreeTX interface {
	ReadOnlyTreeTX
	TreeWriter
}

TreeTX represents an in-process tree-modifying transaction. The transaction must end with a call to Commit or Rollback. After a call to Commit or Rollback, all operations on the transaction will fail. After a call to Commit or Rollback implementations must be in a clean state and have released any resources owned by the TreeTX. A TreeTX can only modify the tree specified in its creation.

type TreeWriter added in v1.0.7 

type TreeWriter interface {
	// SetMerkleNodes stores the provided nodes, at the transaction's writeRevision.
