subclasses of list or dict and haven't implemented any pickle-related
methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__,
or __getstate__), can no longer be pickled. Including memoryview.
Remove various dependencies on dictionary order in the standard library
tests, and one (clearly an oversight, potentially critical) in the
standard library itself - base64.py.
Remaining open issues:
* test_extcall is an output test, messy to make robust
* tarfile.py has a potential bug here, but I'm not familiar
enough with this code. Filed in as SF bug #1496501.
* urllib2.HTTPPasswordMgr() returns a random result if there is more
than one matching root path. I'm asking python-dev for
clarification...
returning 'a' as the delimiter. It now returns '|', but not because I
understood better what the code was supposed to do. Would someone that
understands the idea behind _guess_delimiter() (see its doc string) look to
see if my fallback choice is better than before or if it's just serendipity
that I picked the proper delimiter?
last field was empty it would strip the delimiter and incorrectly guess that
"" was the delimiter. Reported in c.l.py by Laurent Laporte. Will
backport.
