Category: Python Interpreter Core Group: Python 2.2.2 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Csaba Henk (dzsekijo) Assigned to: Nobody/Anonymous (nobody) Summary: double symlinking corrupts sys.path[0] Initial Comment: The bug can be demonstrated as follows (In some Bourne-tpye Unix shell) type $ mkdir d1 d2 && echo 'import sys print sys.path[0]' > d1/script.py && ln -s ../d1/script.py d2 && ln -s d2/script.py . Now see what the three invocations of script.py give us: $ python d1/script.py d1 $ python d2/script.py d2/../d1 $ python script.py d2 -- if script.py imported modules residing in d1, at the third invocation the modules would not be found. ---------------------------------------------------------------------- Comment By: Steven Taschuk (staschuk) Date: 2003-08-28 02:39 Message: Logged In: YES user_id=666873 I confirm this behaviour on Linux 2.4.17 (glibc 2.2.4) with Python 2.2.2 and 2.2.3; but not with Python 2.3. The relevant change seems to be revision 2.114 of Python/sysmodule.c, which implemented SF patch #664376 (q.v.). The change appeared in 2.3a2. Should this be backported to the 2.2 line? ---------------------------------------------------------------------- Comment By: Csaba Henk (dzsekijo) Date: 2003-08-27 12:29 Message: Logged In: YES user_id=754125 I hope the startup message is exact enough: Python 2.2.2 (#1, May 19 2003, 03:15:27) [GCC 3.1] on linux2 ---------------------------------------------------------------------- Comment By: Christos Georgiou (tzot) Date: 2003-08-27 08:46 Message: Logged In: YES user_id=539787 My mistake, I missed the Pyhton 2.2.2 part, sorry. ---------------------------------------------------------------------- Comment By: Christos Georgiou (tzot) Date: 2003-08-27 08:45 Message: Logged In: YES user_id=539787 Which version of Python? With a recent 2.4 (built on Aug 21, sources of Aug 20), on a 2.4.19 SMP kernel: $ mkdir d1 d2 $ echo 'import sys > print sys.path[0]' >d1/script.py $ ln -s ../d1/script.py d2 $ ln -s d2/script.py . $ python d1/script.py /tmp/tzot/d1 $ python d2/script.py /tmp/tzot/d1 $ python script.py /tmp/tzot/d1 Please specify OS too. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=794291&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
