Rebasing the verkle code on top of PBSS broke the overlay transition code in the following way:
rawdb.ReadPreimage
while enumerating the snapshot in order to re-hash the key for insertion in the verkle treeThis means that the overlay conversion method will miss some preimages if they are in the cache and not yet on disk. In order to fix this issue, the conversion code needs to check both the disk and cache stores for preimages. This is done by adding a getter to
trie.Database
, so that it can call(*preimageStore).preimage
.
