Python 2.6 and deprecated modules
Fedora 11 moved to Python 2.6. Now many Python stdlib modules are deprecated (as part of the transition to Python 3.x series). /u/dalcinl/Devel/PETSc/petsc-dev/config/BuildSystem/config/compilers.py:7: DeprecationWarning: the sets module is deprecated import sets /u/dalcinl/Devel/PETSc/petsc-dev/config/PETSc/package.py:7: DeprecationWarning: the md5 module is deprecated; use hashlib instead import md5 /u/dalcinl/Devel/PETSc/petsc-dev/config/BuildSystem/script.py:101: DeprecationWarning: The popen2 module is deprecated. Use the subprocess module. import popen2 We could take two approaches to remove these warnings (I bet all you hate warnings as much as me): 1) Reimplement things using the modern API's, perhaps by using conditional code depending on the Python version and/or using import with try/except blocks. In particular, this will require: a) use the builtin 'set' type (available since Python 2.4) b) use the 'hashlib' module (available since Python 2.5) c) moving from using 'peopen2' to 'subprocess' (BTW, available since Python2.4) will likely remove the need to use 'select', which I commented some time ago it is not supported (for pipes) in native Windows Python (yes, some day I'll have some working code with the native Windows Python). 2) Silent these warnings. I do not think these modules will be ever removed from 2.x series, and porting the whole BuildSystem beast to Python 3.0 is not going to be a 10-minutes task anyway. I personally prefer (1) and volunteer to provide the fixes, even if that is more work than (2). I would like to know your opinions before start to work on this. -- Lisandro Dalc?n --- Centro Internacional de M?todos Computacionales en Ingenier?a (CIMEC) Instituto de Desarrollo Tecnol?gico para la Industria Qu?mica (INTEC) Consejo Nacional de Investigaciones Cient?ficas y T?cnicas (CONICET) PTLC - G?emes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594

I like 1) as well. However someone needs to test the fixes on ancient RH python.

No problem, I have custom installs of old Python's starting from 2.3 and up to current SVN trunk (2.7)... Do you remember what version is the ancient RH Python you are talking about? ?Matt From the phone On Jul 13, 2009, at 1:15 PM, Lisandro Dalcin dalcinl at gmail.com wrote: Fedora 11 moved to Python 2.6.
