[Prevayler-discussion] Revert to old snapshot

[Walter v. I. <wal...@im...>]

Hi all,

Does anybody have experience with reverting the prevalentSystem to
a certain snapshot? I'm thinking about reading the snapshot file
(similar to SnapshotManager.readSnapshot()), and creating a new
transaction that copies the prevalentSystem back to the read system.

I'm too lazy to add undo-functionality to every transaction, only
because the administrator _might_ someday import the wrong file,
currupt the data, and doesn't know how to get the system up and
running again.

Any thoughts if this reading would lead to problems? (running the
replicated configuration). I don't expect any, but I'm just a bit
more careful, as I work both above (transactions) and below (file
system) the library at the same time.

BTW, and when it works, I also have a nice starting point for my
unit tests. ;-)

Regards,
