A very interesting exercise, indeed - especially the observation regarding software (including python itself) that supports installation under alternate names, but doesn't subsequently ensure use of that name in its shebang lines. I just did a quick grep of Lib in my py3k directory, and it looks like cgi.py is incorrectly set to use "/usr/local/bin/python", while the other files with shebang lines are set to "/usr/bin/env python3" as expected. Tools also had a few discrepancies: scripts/2to3.py: /usr/bin/env python (necessary, I think - I believe 2to3 is a 2.x only program) scripts/gprof2html.py: /usr/bin/env python32.3 (Huh? Automated correction gone wrong, perhaps?) scripts/reindent-rst.py: /usr/bin/env python (probably incorrect) pybench: /usr/bin/env python (not sure - has pybench been forward ported on the 3.x branch?) world: /usr/bin/env python (I have no idea what this script is even for) (Note that these examples are a matter of simply respecting the *default* install location for python3, without even getting into questions of altinstall or configured installation locations) Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
