external length available. We now pass a length with all messages in the vm and verify that there is no mismatch with the length from the Snapshot. Fixed a bug in the use of ApiMessageReader. We were always manually adding Snapshot::kHeaderSize to the data, but neglecting to subtract kHeaderSize from the message length. Added FullSnapshotWriter and MessageWriter classes.
