[Zope] Re: FSSession buglette

Are you running FSSession0.4.0? If not please upgrade. The problems you
mention below have been corrected. Nevertheless the first problem you
descripe is not really related to FSSession. What happens is that certain
Zope objects that can be pickled should not be stored in FSSession.
Initially FSSession used marshal to serialize python objects, which is
faster and does not allow storing of instances etc. I moved to pickle at
the users request but one should be careful what he/she stores in
FSSession.

FSsession-0.4.0 should not raise an exception in tpc_finish. If I
understand Zope's two phase commit mechanism, it is ok to raise an
exception in tpc_begin (which corresponds to the 'polling' stage i
believe) but not in tpc_finish. So now potential problems like full
filesystem, unpicklable instances etc should be caught in tpc_begin.
