[ZODB-Dev] Re: Relstorage

[Alan Runyan]

This appears to be a CMFEditions problem not a RelStorage problem.

The ways to escalate a bug:

  Write a test case that demonstrates the bug. Do it yourself.

    a. Ensure tests fail reliably
    b. Email the author with failing tests cases and software versions
to allow him to reproduce
    c. Hope that arthur cares enough to run your tests on the software
packages and fixes it.


I have a feeling its CMFEditions because he is trying to do fancy stuff with the
transaction note(s) in the ZODB.   At a gut level: I feel 100x more comfortable
with Shane's code (ZODB/RelStoage) than CMFEditions.  Which is notoriously
insane.
