That being said, even after applying the patch the testrunner is still not running as expected. More specifically all the tests are failing with this message on stderr.txt:
.../stderr.txt Unknown option: -3 usage: python3 [option] ... [-c cmd | -m mod | file | -] [arg] ... Try `python -h' for more information.
Python 2 does indeed have a -3 switch but Python 3 does not. I am looking but I can't find where this switch is added. If anyone has any idea, please post.

After applying the previous patches, the vast majority of the tests were again failing due to trying to mix strings and bytes in shutil_which(). The following patch fixes that and the tests can finally run. There are still failing ones, but that's a different issue. I opted to add an additional decode() call since it seems less likely to break anything.

Thanks for looking into it, I fixed the things in gunittest in r74032, but I have still some local changes related to shutil_which in core.py I need to test more first.

Hello Anna, is it necessary to redefine encode() and decode()? They are already defined in a bunch of places already...
$ ag -l 'def encode' lib/python lib/python/script/utils.py lib/python/ctypes/preamble.py lib/python/ctypes/ctypesgencore/printer/preamble.py
The one in script/utils.py seems to be OK.

True, but the library is not loaded at that point when I need to decode.

\nis probably redundant.str.strip()already strips that. More specifically it strips all the characters contained instring.whitespace.Other than that, in python3 subprocess output is bytes. The
.decode("utf-8")call is converting the bytes to python3 strings which are the equivalent of unicode strings in python2.Note: the patch should work with python2 too, but I have not tested it.
