Update of /cvsroot/python/python/dist/src/Lib/test
In directory slayer.i.sourceforge.net:/tmp/cvs-serv29798/Lib/test
Modified Files:
regrtest.py
Added Files:
test_largefile.py
Log Message:
Add largefile support for Linux64 and WIn64. Add test_largefile and some minor
change to regrtest.py to allow optional running of test_largefile ('cause it's
slow on Win64).
This closes patches:
http://sourceforge.net/patch/index.php?func=detailpatch&patch_id=100510&group_id=5470
and
