This is so bad on so many levels. Dieter, your problem is just one example. Another is that unit tests have no chance to work reliably either.
How do you solve the unit test issues when the CA is initialized and populated by ZCML only? Do you fully parse the ZCML configuration file before any unit test?
For unit tests we do not use ZCML, we use the zope.component API. In those cases, however, we still do not have side-effects from importing. The unit test case is much easier, since you only test a unit and within this units conflicts of declarations are highly unlikely.
In my specific case, tests would make no problems (as we have only a single thread) -- but of course, you had the general case in view.
Yes, I tried to make a general statement to the generall developer. My intent was not going to make a detailed discussions of all the pros and cons. After all, this was the zope@zope.org mailing list and not zope3-users or zope3-dev. ;-) Regards, Stephan -- Stephan Richter CBU Physics & Chemistry (B.S.) / Tufts Physics (Ph.D. student) Web2k - Web Software Design, Development and Training
