I'm reasonably happy with this.

The test_process files are free of warnings, and make sure to pass EVERYTHING as bytes, which is why there might be some weird juggling around.

Please review. Builders spun. Look green so far.

Thanks for working on this

twistedchecker is red.

  1. in twisted/internet/ stderr.write(msg.encode("ascii"))

On Python3 msg is Unciode right... and then converting unicode to ascii will break in case there are non-ascii characters. Why not encode to utf-8?

  1. For twisted/internet/test/ and twisted/internet/test/ I was expecting a comment describing how they are used by the test suite and what should the test. I found it easier to have them near the test code rather than as a separate file.
  1. In twisted/internet/test/ regarding # Requires twisted.python.modules, why not let the code break and wait for #7804 to be merged... oherwise we might forget to uncomment it.
  1. Is it ok to just use str.decode() without an explicit encoding?
  1. in twisted/test/ maybe we need a comment describing why we can not reuse the _PY3 from compat and need to duplicate this code.

6.Is it ok to convert iterators to list in py27 just to please py3? I would prefer to keep using iterators in Py27, where possible. Ex iteritems(env) instead of env.items() ... and xrange()

Other than the comment above it looks good.

I am leaving this in the review queue so that others can look at it.

I think that point 3 is a blocker for merging these changes. I will focus on reviewing it.

  • Keywords review removed

I think that #7804 is ready to merge and we can remove the reference from this branch.

Please see previous comments and re-submit for review.
