== 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.

== Next Steps ==
 * Eliminate all Python 3 compatibility warnings from [[https://selenic.com/repo/hg/file/default/tests/test-check-py3-compat.t|test-check-py3-compat.t]]
 * Get the entire codebase working with 'from future import absolute_import'
  * This requires fixing some cyclic imports. See [[https://selenic.com/repo/hg/file/default/tests/test-check-module-imports.t|test-check-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'

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.

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'
  • 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
