[Python-Dev] The step command of pdb is broken
Issue http://bugs.python.org/issue13183 raises the point that the step
command of pdb is broken. This issue is 6 months old. A patch and test
case have been proposed. The 'Lifecycle of a Patch' at
http://docs.python.org/devguide/patch.html says
quote
If your patch has not received any notice from reviewers (i.e., no
comment made) after a substantial amount of time then you may email
python-dev@python.org asking for someone to take a look at your patch.

I am the author of pyclewn, a Vim front end to pdb and gdb, and I
would be grateful for any progress on this issue.
The following pdb session shows the problem when running the three
modules main.py, foo.py and bar.py. After the second step command, pdb
does not stop (as it should) at lines foo.py:5 and foo.py:6, nor does
it stop to print the return value of increment().

[Python-Dev] suggestion regarding the contributor agreement form
Hi, It's not very obvious that printing this page http://www.python.org/psf/contrib/contrib-form/ actually prints only the form. Can you rather offer a downloadable image/pdf.

I think the same policies should apply that I want to see followed for any other inclusion into the stdlib: we shouldn't adopt any code that is not explicitly contributed, by it's author. That's not only the legal issues, but also the responsibility for the code. Otherwise, we end up with code that still nobody owns, and the out-of-core version still gets better support.
