Category: Python Interpreter Core Group: Python 2.5 Status: Open Resolution: None Priority: 5 Submitted By: Ronald Oussoren (ronaldoussoren) Assigned to: Nobody/Anonymous (nobody) Summary: sys.path issue if sys.prefix contains a colon Initial Comment: If you install python in a directory whose path contains a colon sys.path will be wrong, the installation directory will be split into two strings and both of them are added to sys.path. The following session demonstrates the problem: bump:~/src/python/:colon bob$ ./python.exe -c "import sys; print sys.path" 'import site' failed; use -v for traceback ['', '/usr/local/lib/python25.zip', '/Users/bob/src/python/', 'colon/../ Lib/', '/Users/bob/src/python/', 'colon/../Lib/plat-darwin', '/Users/bob/ src/python/', 'colon/../Lib/plat-mac', '/Users/bob/src/python/', 'colon/../ Lib/plat-mac/lib-scriptpackages', '/Users/bob/src/python/', 'colon/../ Lib/lib-tk', '/Users/bob/src/python/', 'colon/Modules'] ---------------------------------------------------------------------- >Comment By: Armin Rigo (arigo) Date: 2006-06-25 10:04 Message: Logged In: YES user_id=4771 Internally, CPython sets up its path using a single ':'-separated string. I have no clue how, on Posix, you are supposed to use paths containing ':' in environment variables like $PATH - escape the colons somehow? If there is some escape mechanism, we could support it, both as an internal way to fix the present issue, and directly in parsing PYTHONPATH. If there is no such mechanism, then I can only conclude that having colons in paths will make many other things unhappy, not just Python. ---------------------------------------------------------------------- Comment By: Martin v. Löwis (loewis) Date: 2006-06-24 10:35 Message: Logged In: YES user_id=21627 I think this can be fixed. sys.prefix should be treated as unspittable when constructing sys.path, i.e. sys.prefix should be inserted only after the colon-splitting has been done. Not sure what the best way to implement that would be, though, so unassigning. ---------------------------------------------------------------------- Comment By: Georg Brandl (gbrandl) Date: 2006-06-22 19:08 Message: Logged In: YES user_id=849994 I don't know if something can be done here. A possibility would be, if one path segment doesn't exist, add the colon and the next segment and try again. Martin, do you have an opinion? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1507224&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
