Common bugs
gobject-introspection's /usr/bin/g-ir-scanner appears to be incompatible with python 2.7, this leads to anything building a .gir file failing.
Detailed Description
- Python 2.7 was released on 2010-07-03
This will require a rebuild of everything with Requires: python(abi) = 2.6. See Mass_Rebuild_SOP for how we do a full rebuild of everything - hopefully we can adapt the scripts there to accomplish the rebuild needed for Python 2.7. See Features/Python_2.7/MassRebuild for notes on this specific rebuild.
Porting
Hopefully, little to no porting will be required.
Some notes on changes that may require porting are given on the upstream wiki here: http://docs.python.org/dev/whatsnew/2.7.html#porting-to-python-2-7
Benefit to Fedora
Fedora aims to showcase the latest in free and open source software - we should have the most recent release of Python.
Scope
Python is pervasive in Fedora. Everything from yum to system-config-* to anaconda to pungi is written in Python.
How To Test
Interested testers do not need special hardware. If you have a favorite Python script, module, or application, please test it with Python 2.7 and verify that it still works as you expect.
My own test plan:
- Smoketest of the interpreter
- Run the upstream regression test suite
- Ensure that yum still works
- Ensure that anaconda still works
User Experience
Users should not notice any difference, other than the availability of the 2.7 interpreter
Dependencies
The list is too large to include here.
repoquery --whatrequires --alldeps -s "python(abi) = 2.6" | sort -u
indicates approximately 1200 rpms
Contingency Plan
- There is none. This is do-or-die.
