1. What Works
run-tests.py can pass its own tests (test-run-tests.py and test-run-tests.t) under 2.6, 2.7 and 3.5.
2. Next Steps
Eliminate all Python 3 compatibility warnings from test-check-py3-compat.t
- Get the entire codebase working with 'from future import absolute_import'
- This requires fixing some cyclic imports. See test-module-imports.t for currently whitelisted cyclic imports.
- Make existing modules at least parse with Python 3 (still some Python 2.x syntax)
- Remove 2to3 and have the source be 2.6/2.7/3.5 compatible
- Conditionalize imports for renamed modules
- Get the C extensions compiling correctly in Python 3
Start adding b and u everywhere and using 'from future import unicode_literals'
