Description Peter Berry 2007-06-21 20:25:11 UTC
Description of problem:
http://docs.python.org/ref/slicings.html says that the default 'stop' for a
slice is sys.maxint (I have been told this is only the case for classic classes;
new style classes use None instead). On FC5 for x86_64 it is the 32 bit maxint,
but should be the 64 bit one.

Version-Release number of selected component (if applicable):
2.4.3-9.FC5

How reproducible:
Always

Steps to Reproduce:
See attached test case. Run with python ./slicebug.py. The class implements a
custom __getitem__; indexing an instance with a slice returns the slice's stop.
If the stop is not explicitly specified, it should be the same as sys.maxint and
so the script should print "okay".
  
Actual results:
[pwb@silver python]$ python slicebug.py
bug: slice stop is 2147483647, sys.maxint is 9223372036854775807

Expected results:
[pwb@silver python]$ python slicebug.py
okay

Additional info:
Apparently the bug is present on 2.4.4 on Gentoo as well, but I don't have any
way to test more recent versions.

Fedora Core 5 and Fedora Core 6 are no longer maintained. Is this bug still
present in Fedora 7 or Fedora 8?

 This was "fixed" in python 2.5.x
