Re: [ZODB-Dev] ZODB 3.8.0a1 released
You would now use transaction.savepoint(True). Note also that you don't need to abort a subtransaction or optimistic savepoint, it will be aborted/committed as part of the full transaction.

[ZODB-Dev] ZODB 3.8.0a1 released
I've releases ZODB 3.8.0a1 tp PyPI: http://www.python.org/pypi/ZODB3/3.8.0a1 To see what's in 3.8.0, see the news file: http://svn.zope.org/ZODB/trunk/NEWS.txt?rev=75692view=auto This also includes the recent storage API standardization's, removal of subtransactions, and deprecation of versions. I should have included that in the NEWS file. I'll fix that for the next release. Jim -- Jim Fulton mailto:[EMAIL PROTECTED]Python Powered!

You can create a savepoint or you can use the connection add method to give a new object a _p_jar and _p_oid before a commit. (There are cases where the object of interest isn't handy and using a savepoint if more convenient.) Are savepoints relevant for this (ab)use? Yes I don't think this idiom was ever formally documented, it was just an informal hack that I picked up somewhere (I forget from whom). I've used this trick with savepoints.
