Hi! On Windows, this 15 months old change in ZConfig sets the default hostname for inet_address to 'localhost': http://svn.zope.org/ZConfig/?rev=376&view=rev I have no idea why this was changed, the checkin message is not very helpful: "fix the default hostname for address datatypes for Windows" This ZConfig change is responsible for the Zope 2.8 release blocker http://www.zope.org/Collectors/Zope/1728 (the relevant info is in http://www.zope.org/Collectors/Zope/1507) and caused similar problems with Zope 3 http://www.zope.org/Collectors/Zope3-dev/383 http://mail.zope.org/pipermail/zope3-dev/2005-March/013770.html So if nobody can tell me why ZConfig was changed, I propose to 1.) revert the change and tag a new version of ZConfig 2.) update ZEO: the ZEO tests expect the old behavior, see http://mail.zope.org/pipermail/zope3-dev/2005-March/013794.html 3.) update Zope 2 trunk and Zope 3 trunk to the new versions of ZConfig and ZEO 4.) fix http://www.zope.org/Collectors/Zope/1507 and http://www.zope.org/Collectors/Zope3-dev/383 I'd volunteer to do the necessary changes in Zope 2. Any comments? Any volunteers for the other tasks? Cheers, Yuppie BTW: Why is ZConfig not a svn:external in Zope 2 and 3?
