New submission from Alexander Boyd:
Itertools would benefit greatly from a function (which I've named intersperse,
after Haskell's equivalent) for yielding the items of an iterator with a given
value placed between each. Sort of a str.join-like function, but for arbitrary
Alexander Boyd added the comment:
Then perhaps the docstring of relative_to could note this (like relpath does),
or a separate method that's explicitly not symlink safe created.
Or better yet, what about a function that does (or at least tries to) give the
correct answer in the fa
New submission from Alexander Boyd:
pathlib.Path.relative_to() blows up when given a path that's not an ancestor of
the path on which relative_to is being called:
>>> pathlib.Path("/usr/bin").relative_to("/etc")

They're providing both /etc/oracle-release and /etc/redhat-release (as Oracle
Linux is based on RHEL).
I've attached /etc/oracle-release for reference.

New submission from Alexander Boyd:
Tested on 3.3.2 and 2.6.6.
On Oracle Linux, platform.linux_distribution detects the current distribution
as Red Hat Enterprise Linux:
>>> import platform
>>> platform.linux_distribution()

Ok. Yeah, I won't argue that it's pretty :-)

That's my point. My version, sane_total_ordering.py, fixes this by using
traditional functions and explicit NotImplemented checks.

I've attached a file demonstrating the stack overflow. It assumes
total_ordering has been defined as per new_total_ordering.py.

Alexander Boyd added the comment:
Ok. I did write that against Python 2, so I wasn't aware of __eq__ and __ne__.
I'll keep that in mind.
I am curious, however, as to how this could break existing code. It seems like
code that relies on a stack overflow is already broke
Alexander Boyd added the comment:
But it seems pointless to force someone to implement all of the rich comparison
methods when they may want to do something as simple as this:
class Foo:
...
def __lt__(self, other):
if not isinstance(other, Foo):
return
Alexander Boyd added the comment:
This is not fixed. The accepted fix doesn't take NotImplemented into account,
with the result that comparing two mutually-incomparable objects whose ordering
operations were generated with total_ordering causes a stack overflow instead
of the exp
