[Qemu-devel] [PATCH 0/6] docker: Port to Python 3

[Eduardo Habkost]

This series makes tests/docker/docker.py compatible with both
Python 2 and Python 3, and adds type annotation to make
maintenance easier in the future.

A note about dockerfile encoding
--------------------------------

One decision I made while working on this was to open dockerfiles
in text mode instead of binary mode, to make the code simpler and
safer.

This means we won't support dockerfiles that are not valid utf-8
data, but I see that as a feature and not a bug.  :)

Opening dockerfiles in binary mode and treating its contents as
byte sequences instead of text is possible if we really want to,
but I don't think it would be worth the extra code complexity.

Eduardo Habkost (6):
  docker: Use BytesIO instead of StringIO
  docker: Always return int on run()
  docker: Add type annotations
  docker: Use os.environ.items() instead of .iteritems()
  docker: Make _get_so_libs() work on Python 3
  docker: Open dockerfiles in text mode
