[Qemu-devel] [RFC 00/10] [TESTING NEEDED] python: futurize --stage1 (Python 3 compatibility)

[Eduardo Habkost]

TESTING NEEDED: Due to the amount of changes, I didn't test all
scripts touched by this series.  If you are responsible for any
of the touched files, I would appreciate help on testing the
series.

>From the futurize[1] documentation:

> This applies fixes that modernize Python 2 code without
> changing the effect of the code.  With luck, this will not
> introduce any bugs into the code, or will at least be trivial
> to fix. The changes are those that bring the Python code
> up-to-date without breaking Py2 compatibility.  The resulting
> code will be modern Python 2.6-compatible code plus __future__
> imports from the following set:
>
>     from __future__ import absolute_import
>     from __future__ import division
>     from __future__ import print_function
>
[...]
> The goal for this stage is to create most of the diff for the
> entire porting process, but without introducing any bugs.  It
> should be uncontroversial and safe to apply to every Python 2
> package.  The subsequent patches introducing Python 3
> compatibility should then be shorter and easier to review.

This series run all the fixers from futurize --stage1 on all
Python code in the tree.  To make review and testing easier, I
have run the fixers separately instead of doing all changes in a
single patch.
