Hi!

Recently encountered a problem with the python-demjson rpm I maintain:
The demjson package does not use setuptools, so, in accordance with
the python packaging guidelines, I used the trick of preloading
setuptools prior to executing setup.py, for F7 and F8 only. This
produces an egg-info directory, fine.

Now, for F9, egg-info is generated automatically, but it turns out
that this produces an egg-info file instead of an directory. This in
turn causes problems when upgrading from F8 to F9, because rpm can't
replace a dir with a file.

Any advices on how to solve this?


Do you have a reason to need eggs on F7 and F8?

Thats strange, I thought it was added because of policy as opposed to reason. Firstaidkit has no need for eggs, but the reviewer insisted on adding to them. FWI, firstaidkit chooses to handle the plugins with rpm, which is a valid alternative to eggs.

Maybe the Guidelines need rewording. Can you point at something in the Guidelines that could be improved to show that using setuptools to add eggs in F7/F8 is optional? (All packages must handle the egg files in F9+ and they must handle eggs created by packages which use setuptools normally. The optional part is when adding eggs to a package which doesn't provide them on its own.)

maybe change it a little:
Change the "when to provide eggs"  in http://fedoraproject.org/wiki/Packaging/Python/Eggs
"
Starting with Fedora 9, our python package provides egg-info for any distutils and setuptools packages. Since this establishes a base of functionality that upstream authors can expect, we need to be sure we include those files when needed. In Fedora 8 and below eggs can be provided when the package uses setuptools.  In this case eggs are optional.  In F9+ eggs have to be provided when the upstream package provides them and are optional when the upstream package does not provide them.
"
What do you think about this?
