py3: byte-stringify literals in contrib/phabricator.py as example Transformed by contrib/byteify-strings.py and adjusted exceeded lines manually. Some of b''s would be wrong as the phabriactor extension has to work with JSON data. # skip-blame just many b prefixes

byteify-strings: remove superfluous "if True" block

byteify-strings: try to preserve column alignment

byteify-strings: do not rewrite system string literals to u'' It would make things worse on Python 2 because unicode processing is generally slower than byte string. We should just leave system strings unmodified.

byteify-strings: do not rewrite iteritems() and itervalues() by default We can't do that automatically due to performance concerns.

byteify-strings: drop import-line hack This is ugly, and valid only for Python 3. We'll need to find a different way if we want to get rid of the code transformer at all.

byteify-strings: add --inplace option to write back result

byteify-strings: add basic command interface

byteify-strings: fork py3 code transformer to make it a standalone command I'm thinking of making a one-off s/''/b''/g change for overall codebase to make linter happy. We could do that without maintaining the script, but I think it will be somewhat useful for extension authors. So it is in contrib.
