Folks, Guido,
I believe PEP 3144 is ready for your review. When you get a chance, can
you take a look/make a pronouncement?
Besides what has already been said in the thread, I have a bunch of
comments:
It should be noted
that __len__ doesn't work as expected since python internals has this
limited to a 32 bit integer and it would need to be at least 128 bits
to
work with IPV6.
You should clarify what it means: does the result get truncated, or is an
error thrown when it can't fit inside an int?
I'll clarify this, but it looks like this:
len(xrange(0xFFFFFFFFFFFFFFFFFFFFFFFFF))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: long int too large to convert to int
basically, __len__(self): can only return an int. At least that's what
I recall from the discussion.
FWIW, the limitation remains in Py3, with a modified error msg.
>>> len(range(0xFFFFFFFFFFFFFFFFFFFFFFFFF))
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
len(range(0xFFFFFFFFFFFFFFFFFFFFFFFFF))
OverflowError: Python int too large to convert to C ssize_t
