Introducing Python 3.5 nightly builds for Fedora

Hi everybody, I'd like to introduce a new project of Slavek Kabrda and mine: Copr repository with nightly builds of development version of Python 3. http://copr.fedoraproject.org/coprs/churchyard/python3-nightly/ How does it work? ================= Each night, at 00:01 CET/CEST, dgroc [1] is run and checks out if any of the following upstream projects has some new commits in master/default branch: * cpython * setuptools * pip * wheel If so, it creates SRPM with code from that specific new commit and builds it in the copr repository. Is is being built as a software collection, not to break system python3 package (that being in critpath once Python 3 will be the default). Benefits ======== This will let us know immediately when our patches of Python 3 package are broken. We can react when that happens a we know exactly what commit (or at lest what day) broke it. This will avoid a big "fix all the patches" spree once Python 3.5 is stable and hits Fedora. The builds also run the test suite, so we can see regressions when they happen and we can communicate with Python upstream fast and flexible (again, instead of a mass failure once Python 3.5 hits Fedora). It also let us and you to test if your packages build and run with Python 3.5, so we can avoid more confusion once Python 3.5... you see what I mean. Other than the packaging reasons: Fedora might attract Python enthusiasts and developers as it is most likely the only Linux distro that has development version of Python packaged nightly. Developers and powerusers can play with new features committed yesterday just by doing `dnf update`. How to use it ============= Ad the repository (with dnf copr plugin, or manually), and install python35 package. That installs the software collection and you can use it as any other software collection: $ scl enable python35 python Or $ scl enable python35 bash You can also install packages from PyPI: # scl enable python35 bash # pip install ipython How to (test)build my package against Python 3.5 ================================================ If you want to build your package against Python 3.5, you can do it in the following way: 1. Update the spec by adding SCL related macros, see [2][3] 2. In mock or Copr, add the repository and add the following packages to the chroot: scl-utils-build python35-build [4][5] 3.
