I just wasted some time chasing down being unable to run the Python test suite because the testanydbm tests were segfaulting. Removing the bsddb module allowed the tests to run without segfaulting.

(FWIW, I'm running on Fedora Core 1, with db4-4.1.25-14) Where is the sf bugreport? what python cvs version/date was this, where did the segfault occur, what stack trace does the coredump show? testanydbm.py with bsddb using 4.1 or 4.2 do not coredump for me, if theres a bug i'd like to fix it.

Fair enough, I'll submit one.

I get the impression that this is a common problem. Berkeley DB APIs often change in non-backward compatable ways that cause this sort of problem. Perhaps these APIs change too rapidly to allow the bsddb extension to be included in the distribution. I assume that this is the fault of the Berkeley DB libraries, and not the extension, but I don't really know. :/ -1 The Sleepycat BerkeleyDB API rarely changes.

This has not been my experience, but ...

The extension is much more mutable as support for more of the sleepycat apis are added and enhancements are made to the compatibility interface, i'd expect this type of bug to be there first.

OK.

It sounds like you are very committed to making tis work. That means a lot to me and is greatly appreciated.
