Package: python2-pyro4
Version: 4.53-1
Severity: grave
Justification: renders package unusable
When trying to import Pyro4 in python2.7 following pops up (example is from
ipython but exactly the same output is from the app when trying to use it):
In [1]: import Pyro4

'selectors34' is a backport of python3.4 'selectors' to python2.7, which is
replacement for python2.7 'select'.
Problem is that 'selectors34' is not packaged thus not available in Stretch and
I'm afraid it's too late for it to be allowed in.
Therefore I see following options:
1. Revert python2-pyro4 (src:Pyro4) to 4.43-1 this one is using 'select' thus
doesn't require 'selectors34'.
2. Patch 4.53-1 with something like this:
if sys.version_info[:2] == (2,7):
import select as selectors
else:
import selectors
in the socetserver/multiplexserver.py instead of try except for importing it
and purge requires.txt file from the egg-info.
3. Package selectors34 and convince release managers to allow it in.
