| − | | |
| − | '''FINISHED''' Dogtag 10.6 on Fedora 28 will use Python 3 by default
| |
| − | | |
| − | = Motivation =
| |
| − | | |
| − | The change is motivation by [https://fedoraproject.org/wiki/FinalizingFedoraSwitchtoPython3 Fedora's Switch to Python 3] and [https://fedoraproject.org/wiki/Packaging:Python Fedora's packaging guidelines for Python]. Fedora is slowly deprecating Python 2 support in favor of Python 3. FreeIPA is also turning a Python 3-only package. For 4.7-dev, all Python 2 dependencies have been removed -- except for Dogtag. Only Dogtag pulls in Python 2.7 for pkispawn, pkidestroy, upgrade script and pki client command.
| |
| − | | |
| − | = Python dependency =
| |
| − | | |
| − | ; pki-base
| |
| − | : provides /usr/sbin/pki-upgrade and /etc/pki/pki.conf
| |
| − | ; pki-base-python2 (virtual package in Dogtag 10.5)
| |
| − | : provides pki client package for Python 2
| |
| − | ; pki-base-python3
| |
| − | : provides pki client package for Python 3
| |
| − | ; pki-server
| |
| − | : provides /usr/sbin/pkispawn, /usr/sbin/pkidestroy and pki.server package (currently Python 2)
| |
| − | | |
| − | == Fedora 27 ==
| |
| − | | |
| − | For Fedora 27 and Dogtag 10.5, it ''should'' be possible to build Dogtag packages with Python 3 as default for all commands. At the moment, pki-base-10.5.1 depends on Python 2.7. This would help freeIPA to test Python 3-only supporting with a custom build of Dogtag 10.5.
| |
| − | | |
| − | Although Python 3 support has seen some testing already, it might be too risky to change the default packages in Fedora 27 to Python 3.
| |
| − | | |
| − | == Fedora 28 ==
| |
| − | | |
| − | Starting with Fedora 28, freeIPA '''must''' not depend on Python 2 at all. This means pki-base and all Dogtag commands like pkispawn must use Python 3. The Python 2 client package pki, provided by package name ''pki-base-python2'', must still be available for legacy support.
| |
| − | | |
| − | ; pki-base
| |
| − | : changed to Python 3 / pki-base-python3
| |
| − | ; pki-base-python2
| |
| − | : optional
| |
| − | ; pki-server
| |
| − | : changed to Python 3
| |
| − | | |
| − | == Fedora 29+ ==
| |
| − | | |
| − | For Fedora 29 and later, it should be possible to build Dogtag without Python 2 in build root. The cmake build system and RPM spec file should no longer assume that ''python'' or ''python2'' commands are available.
| |
| − | | |
| − | The pki-base-python2 package should still be available and packaged for Fedora 29 when the build root contains Python 2.
| |
| − | | |
| − | = Packaging guideline violations =
| |
| − | | |
| − | Dogtag's Python package names violate the Fedora packaging guidelines. During the RPM spec file update, we should also update the package names.
| |
| − | | |
| − | ; pki-base-python2 -> python2-pki
| |
| − | : rename Package to python2-pki that provides a virtual package pki-base-python2
| |
| − | : requires: pki-base
| |
| − | ; pki-base-python3 -> python3-pki
| |
| − | : rename Package to python3-pki that provides a virtual package pki-base-python3
| |
| − | : requires: pki-base
| |
| − | ; pki-base
| |
| − | : contains only scripts and configs
| |
| − | ; requires either python2-pki or python3-pki depending on ''WITH_PYTHON3_DEFAULT''
| |
| − | | |
| − | We should also look into using macros like %{?python_provide:%python_provide python3-%{srcname}}
