Additional python34 components for epel7
by Denis Fateyev 19 Jan '16

19 Jan '16

Hello there, To package some python3-based stuff I need 'msgpack', 'llfuse', 'Cython' modules built for Python 3.4 which is the current version of Python 3 in epel7. Would it be reasonable to file a bug against 'python-msgpack', et al. in epel7 to adapt the package spec and get 'python34-msgpack' etc. packages, or there are any objections against that? Thanks, -- wbr, Denis.

New (optional) python egg dependency generator for RPM
by Neal Gompa 23 Nov '15

23 Nov '15

Hello all, I recently upstreamed some fixes to a new RPM dependency generator that will be available as an option for distributions to enable. The new generator uses python .egg data to generate Provides and Requires in the form of pythonXegg(Y), where X is the Python major version and Y is the module. The code for the new generator is available in RPM's GitHub[1]. I've also made a package in Copr[2] for members of the Python SIG to test out and provide feedback. I would greatly appreciate it if the Python SIG would try it out. It's available for Fedora 22, 23, and rawhide through the Copr. There is one issue I haven't quite been able to figure out, though. When being run using Python 3 (Fedora 23+ default), it appears to add an unversioned "python(abi)" Require to modules on top of the versioned one. This does not occur when the code is being run in Python 2 (Fedora 22 default), and I cannot quite figure out why this is happening. If anyone has any idea, please let me know, as I would definitely like this to fix this issue so that it is perfectly functional on both Python 2 and Python 3. The Python interpreter being used can be switched in /usr/lib/rpm/fileattrs/pythoneggs.attr Best regards, Neal [1]: https://github.com/rpm-software-management/rpm/blob/master/scripts/pythoneg… [2]: https://copr.fedoraproject.org/coprs/ngompa/rpm-depgen-pythoneggs/ -- 真実はいつも一つ！/ Always, there's only one truth!

Python 3.5 for Fedora 23 in COPR
by Matej Stuchlik 13 Nov '15

13 Nov '15

Hey folks, a while ago I've created a COPR repo [0] with Python 3.5 for f23, I haven't had any bug reports so far, so it should be OK to use. You can install it with: $ dnf copr enable -y mstuchli/Python3.5 $ dnf install -y python35-python3 Then you can use the python3.5 and pip3.5 executables. Some more information is available at [1]. Enjoy! [0] https://copr.fedoraproject.org/coprs/mstuchli/Python3.5/ [1] http://synfo.github.io/2015/11/13/Python-3.5-in-Fedora/

[HEADS UP] Ongoing rebuild of Python3.5 in Rawhide
by Robert Kuska 04 Nov '15

04 Nov '15

There is ongoing rebuild of Python3.5 in rawhide's side-tag f24-python3. I would like to ask all maintainers to rebuild their packages (which depend on python3) within the f24-python3 side-tag. To rebuild your package simply run: `fedpkg build --target f24-python3` You can find all packages that were already rebuilt here: http://taiga.cloud.fedoraproject.org/project/rkuska-python35-rebuild/kanban Feel free to add your package once your build pass successfully. Side-tag will be merged hopefully by the end of the week, mass rebuild will follow to avoid breakage of rawhide. Tracking bug to link rebuild related bugs to: https://bugzilla.redhat.com/show_bug.cgi?id=1269756 https://fedoraproject.org/wiki/Changes/python3.5 -- Robert Kuska {rkuska}
