Critical Path: New Python version (2.7.6) in Rawhide
by Tomas Radej 31 Jan '14

31 Jan '14

Hi, I have updated Python in Rawhide to version 2.7.6. The build is already tagged as f21. As far as I checked, the API/ABI should remain the same. Most patches applied neatly, only a few needed a rebase, and two were 1:1 incorporated upstream. If something Python-related starts acting up, try looking at this first, and if this version is indeed the cause, don't hesitate to untag the build and/or let me know, I will fix it. Cheers, -- Tomas Radej <tradej(a)redhat.com>

Hi everybody, just a heads up that I'll build python-sqlalchemy-0.9.1 in Rawhide shortly. If your package uses SQLAlchemy, please check "What's New in SQLAlchemy 0.9?"[1] for changes that might affect you. And test stuff, of course.

python compat package change needed
by Toshio Kuratomi 06 Jan '14

06 Jan '14

The new setuptools shipped in F20+ has one change that breaks things for a subset of python packages. I'm proposing a very small guideline change for the Pyhton Eggs guidelines to address that. Maintainers of backwards and forward compat packages will likely want to address this as it will break upgrades of those backwards compat packages from f19 to f20. When we ship backwards compat pyhton modules we take advantage of a feature of pythhon eggs to install the multiple versions: https://fedoraproject.org/wiki/Packaging:Python_Eggs#Multiple_Versions The guidelines say to use the following command line for performing the install: easy_install -m --prefix $RPM_BUILD_ROOT%{_usr} dist/*.egg In Fedora 19's setuptools package, this resulted in a new directory being installed into site-packages that held the versioned egg. In Fedora 20's setuptools package, this command results in a zipped egg file being installed into site-packages. The zipped egg has the same filename as the previous directory. This causes problems for rpm as rpm cannot handle replacing a directory with a file without jumping through hoops. Because rpm cannot perform that replacement, we end up with bug reports like this: https://bugzilla.redhat.com/show_bug.cgi?id=1047570#c0 where the user is unable to upgrade the F19 package to the F20 package. The solution is to force easy_install to install unzipped eggs rather than zipped eggs. This can be done via a command line switch, -Z. I've proposed adding that switch to the Pyhton Eggs guidelines: https://fedorahosted.org/fpc/ticket/378 If you get similar bug reports to the one menitoned, you can add the switch to workaround the problem now. I'll send a new message to this list if (for some reason I don't know about) adding -Z is deemed unacceptable. -Toshio
