During the last few months we have +been working hard to migrate Gentoo to Python 3, and we have finally +reached the point making it possible for the vast majority of our users +to run a system free of Python 2.7 packages (except for the interpreter +itself). + +The few remaining high profile packages (e.g. dev-python/cython) +are preserving Python 2.7 only for a very few uncommon packages. +For this reason, we have decided to create new revisions of them having +Python 2.7 removed. If you do not need Python 2.7 there, your package +manager should upgrade these packages to the new revisions. + +Please note that you may need to manually uninstall any Python 2.7 +packages installed from third-party repositories and/or run `emerge +--depclean` first to remove orphan packages. The recommended process +for Portage users is: + + emerge --depclean + emerge -vDuU @world + emerge --depclean + +Please note that the Python 2.7 interpreter (without additional Python +packages) remains necessary to build a few high profile packages, +in particular Chromium, Mozilla software and PyPy. If you build either +of these packages from source, you will not be able to permanently +remove Python 2.7 from your system. + +We are going to preserve CPython 2.7 (and PyPy2.7) for as long +as necessary and provide security fixes to the best of our ability. +However, please note that we are not able to dedicate resources to +auditing Python 2.7's code and with little community interest in that, +it should be considered potentially vulnerable. + +If your projects still rely on Python 2.7, we would like to once again +encourage you to migrate them to Python 3. However, if you really need +to run them, we suggest using a virtualenv. To create a new Python 2.7 +environment, install dev-python/virtualenv and use the following option: + + virtualenv -p /usr/bin/python2.7 ... + +To create a PyPy2.7 environment: + + virtualenv -p /usr/bin/pypy ... + +Modern versions of pip should be able to automatically select older +versions of packages that still support Python 2.7. Please note that +these versions are generally no longer supported. They can be buggy, +vulnerable or simply incompatible with one another. + +Please do not forget to add dev-lang/python:2.7 to your @world set +or it may get depcleaned once all package dependencies are gone. |
