From 4f40d058ccc030107bc33716401f8c0f4a7230d9 Mon Sep 17 00:00:00 2001 From: Adrian Tschira Date: Fri, 6 Apr 2018 22:57:06 +0200 Subject: [PATCH] Replace old-style raise with six.reraise The old style raise is invalid syntax in python3. As noted in the docs, this adds one more frame in the traceback, but I think this is acceptable: in () 16 except: 17 pass ---> 18 six.reraise(*x) /usr/lib/python3.6/site-packages/six.py in reraise(tp, value, tb) 691 if value.__traceback__ is not tb: 692 raise value.with_traceback(tb) --> 693 raise value 694 finally: 695 value = None in () 9 10 try: ---> 11 x() 12 except: 13 x = sys.exc_info() Also note that this uses six, which is not formally a dependency yet, but is included indirectly since most packages depend on it.
