Detailed Description

Python 3.2 is the latest release of the Python 3 language. Although the core language has been frozen (to allow the non-CPython implementation of Python to "catch up" with CPython), 3.2 contains hundreds of fixes and tweaks throughout.

Benefit to Fedora

Fedora aims to showcase the latest in free and open source software - we should have the most recent release of Python 3.

Scope

The core python3 src.rpm has been rebuilt with the latest 3.2 code.

There have been some slight changes to the on-disk layout of how Python organizes extension modules: PEP-3147 and PEP-3149.

https://fedoraproject.org/wiki/Python3#Python_3_already_in_Fedora indicates that as of Fedora 15 there are currently about 25-30 extension modules for Python 3 available via RPM. These will need rebuilding to cope with disk layout changes, and for the latest .pyc/.pyo bytecode format. I will do these as necessary before the release. Many have already been done by package maintainers.

How To Test

Interested testers do not need special hardware. If you have a favorite Python 3 script, module, or application, please test it with Python 3.2 and verify that it still works as you expect.

My own test plan:

  • Smoketest of the interpreter
  • Run the upstream regression test suite (this is done during %check)

User Experience

Users should not notice any difference, other than the availability of the 3.2 interpreter

Dependencies

See notes in "Scope" above.

Contingency Plan

The bulk of the work is done, and appears stable.

Release Notes

The system Python 3 stack has been upgraded to 3.2 (the system Python 2 stack remains at 2.7), bringing in hundreds of fixes and tweaks; for a list of changes see http://docs.python.org/dev/whatsnew/3.2.html
