> I wonder why you don't always create .egg directories. I've now found this section in the documentation which seems to have the reason: http://peak.telecommunity.com/DevCenter/EasyInstall#compressed-installation Apart from the statement "because Python processes zipfile entries on sys.path much faster than it does directories." being wrong, it looks like all you'd have to do, is make --always-unzip the default. Another nit which seems to have been introduced in 0.6a11: you now prepend egg directory entries to other sys.path entries, instead of appending them. What's the reason for that ? Egg directory should really be treated just like any other site-package package and not be allowed to override stdlib modules and packages without explicit user action by e.g. adjusting PYTHONPATH. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Apr 28 2006) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,FreeBSD for free ! :::: _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
