I'm guessing we're talking about different things, then. These things have
been discussed recently here:
+ Reports of bsddb3 database corruption in spambayes.
+ Likewise in Richie Hindle's multithreaded test driver, plus
+ Hangs and AssertionErrors in the tests from
Richie's program uses only our wrapper's __delitem__, __setitem__ and
__getitem__ implementations. spambayes does the same. While some tests in
test_thread.py use transactions, the AssertionError Skip reported was in a
test that does not use transactions:
Fred and Barry also saw the same kind of AssertionErrors in
SimpleThreadBase.writerThread, on the same line. Finally, the hangs Barry
and I saw were in test02_SimpleLocks, which is also devoid of transactions.
So I haven't seen any evidence of problems with transactions -- unless these
things use transactions implicitly in some way.
