ZTK and Python 2.6, zope.app.zcmlfiles and zope.app.security globalmodules.zcml
I'm trying to get the ZTK KGS tests working with Python 2.6. The tests generate lots of deprecation warnings in part because lots of packages use zope.app.zcmlfiles and zope.app.zcmlfiles includes globalmodules.zcml in zope.app.security and globalmodules.zcml causes lots of standard modules to get imported, including mhlib, which is deprecated in Python 2.6. Whew. :) I know we want to stop using zope.app.zcmlfiles. This make take a while. Too big a job for right now. We should stop using globalmodules.zcml. It's too expensive, too scary, and causing this deprecation warning. If I just delete it's contents, no ztk tests break. :/ I see 3 options, from lowest to highest (but maybe still low) risk: A. Suck it up and live with the deprecation warnings until we get rid of zope.app.zcmlfiles B. Remove the security declaration for mhlib from globalmodules.zcml. Is anyone actually building web applications that publish MH mail folders? C. Stop including globalmodules.zcml from zope.app.zcmlfiles Opinions? FWIW, I vote for B. Jim -- Jim Fulton

globalmodules also imports deprecated modules sets and multifile. :( I just noticed that globalmodules uses a trick to avoid importing md5 and sha in Python 2.6 by checking whether json is importable. I'll use this same trick for sets, multifile, and mhlib. :) Jim -- Jim Fulton

I vote for C (anybody who wants the 'globalmodules.zcml' behavior back can add one line to their 'site.zcml;), but could live with B. The ZTK needs to impose as *little* policy as possible.
