The undo API has changed with ZODB 3.10. As noted in the changelog: "The API for undoing multiple transactions has changed. To undo multiple transactions in a single transaction, pass a list of transaction identifiers to a database's undoMultiple method. Calling a database's undo method multiple times in the same transaction now raises an exception." Your code calls undo multiple times, and needs to be changed accordingly.
