[ Jim Fulton ]:
|Before we talk about adding it anywhere, I'd like to see the
|semantics defined more clearly.
I guess what Chris meant was:
Given a pivot point in time (date and time),
for *all* objects in the database (the whole Data.fs)
will suffer UNDO over transactions whose timestamp is
greater (more recent) than the given pivot timestamp.
Is this what you meant Chris ?
Nevertheless, some doubts:
- if you have several ZODB mount points, pointing
to different files ? Should all be considered
as a single database and suffer the same massive
UNDO operation ?
- Should that mega-undo imply in a ZODB pack as well ?
I suppose not.
- Wouldn't it be nice to figure out a way to specify
a restricted scope for this operation ? For instance,
give a relative root or set of meta_types ?
I hope this issues will narrow down (but not exhaustively)
the need for more precise semantics.
