Because the original post is discussing the scenario where you are installing an egg that was already built by someone else. You're correct that the fetch_build_eggs() method can and should just use the attribute directly. > At any rate, I'm attaching a partially-working patch. I'll take it for a spin. It looks pretty good, except that easy_install doesn't use it. I can go ahead and add that bit. The doc is a bit, um, terse, but I can flesh it out a bit I guess. :) >I could get the 'dependency_links.txt' file to be created, but couldn't >figure out how to use the pkg_resources facilities for reading it while >inside 'fetch_build_eggs'. You don't need to; it's the easy_install command that needs to do that, in process_distribution() I believe. > I alos ran into the problem that, since the >'test' command doesn't support the usual 'easy_install' arguments (my >original reason for posting), I couldn't control where the downloaded >packages would be installed: they went directly in my local sandbox. That's where build dependencies are supposed to go, actually; building and testing a package shouldn't cause build-time dependencies to be permanently installed on the build system, without an explicit action. You can always "easy_install *.egg" if you want to make them permanent. >My original plan was to add the 'easy_install' command line args to >the 'test' command, which would have allowed: > > $ /path/to/python setup.py test \ > --find-links="http://download.zope.org/distribution"; > >Under the mechanism you redireted me to, I need to add the equivalent >URL into zi/setup.py as a 'dependency_link' argument to 'setup', and >then arrange for that value to be used as the 'find_links' value for >the 'test' command. Is that what you intended? Yes; it should get passed to the find_links argument given to the easy_install command instance created by Distribution.fetch_build_eggs(), which is what your patch does. _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
