Open Issues ===========

- *Code review policy for the ``py3k-jit`` branch.* How does the CPython  community want us to procede with respect to checkins on the ``py3k-jit``  branch? Pre-commit reviews? Post-commit reviews?

 Unladen Swallow has enforced pre-commit reviews in our trunk, but we realize  this may lead to long review/checkin cycles in a purely-volunteer  organization. We would like a non-Google-affiliated member of the CPython  development team to review our work for correctness and compatibility, but we  realize this may not be possible for every commit.

The feedback we've gotten so far is that at most, only larger, more critical commits should be sent for review, while most commits can just go into the branch. Is that broadly agreeable to python-dev?

...

- *How to link LLVM.* Should we change LLVM to better support shared linking,  and then use shared linking to link the parts of it we need into CPython?

The consensus has been that we should link shared against LLVM. Jeffrey Yasskin is now working on this in upstream LLVM. We are tracking this at http://code.google.com/p/unladen-swallow/issues/detail?id=130 and http://llvm.org/PR3201.

...

- *Prioritization of remaining issues.* We would like input from the CPython  development team on how to prioritize the remaining issues in the Unladen  Swallow codebase. Some issues like memory usage are obviously critical before  merger with ``py3k``, but others may fall into a "nice to have" category that  could be kept for resolution into a future CPython 3.x release.

The big-ticket items here are what we expected: reducing memory usage and startup time. We also need to improve profiling options, both for oProfile and cProfile.

...

- *Create a C++ style guide.* Should PEP 7 be extended to include C++, or  should a separate C++ style PEP be created? Unladen Swallow maintains its own  style guide [#us-styleguide]_, which may serve as a starting point; the  Unladen Swallow style guide is based on both LLVM's [#llvm-styleguide]_ and  Google's [#google-styleguide]_ C++ style guides.

Any thoughts on a CPython C++ style guide? My personal preference would be to extend PEP 7 to cover C++ by taking elements from http://code.google.com/p/unladen-swallow/wiki/StyleGuide and the LLVM and Google style guides (which is how we've been developing Unladen Swallow). If that's broadly agreeable, Jeffrey and I will work on a patch to PEP 7.

I have found the Google C++ style guide good so I am fine with taking ideas from that and adding them to PEP 7. -Brett
