[Zope-dev] deciding whether to do work in tpc_vote or tpc_finish

[Chris Withers]

Hi All,

I need to write a data manger that interacts with a transactional system 
that doesn't support two phase commit.

Looking for inspiration, I went to look at zope.sqlalchemy and 
zope.sendmail.

In the non-tpc situation, the former does the "commit" in tpc_vote while 
the latter does it in tpc_finish.

Which is "right"? What are the tradeoffs involved?

cheers,

Chris
