[Python-Dev] PEP 394 request for pronouncement (python2 symlink in *nix systems) (original) (raw)

There are two issues that I know of for OS X. One is just getting a python2 symlink into the bin directory of a framework build. That's easy.

Where exactly in the Makefile is that reflected? ISTM that the current patch already covers that, since the framwork* targets are not concerned with the bin directory.

The other is managing symlinks (python, python2, and python3) across framework bin directories; currently there's no infrastructure for that. That part will probably have to wait until PyCon.

What is the "framework bin directory"? The links are proposed for /usr/local/bin resp. /usr/bin. The proposed patch already manages these links across releases (the most recent install wins).

If you are concerned about multiple feature releases: this is not an issue, since the links are just proposed for Python 2.7 (distributions may also add them for 2.6 and earlier, but we are not going to make a release in that direction).

It may be that the PEP becomes irrelevant before it is widely accepted: if the sole remaining Python 2 version is 2.7, users may just as well refer to python2 as python2.7.
