with Cawlishaw by mail, and he basically confirmed that to these is_*
operations, there's no need to return Decimal(0) and Decimal(1) if
the language supports the False and True booleans.

Also added a few tests for the these functions in extra.decTest, since
they are mostly untested (apart from the doctests).

Thanks Mark Dickinson

don't worry about any self-referring tuples.

Python code; but it is possible from C.  object.__str__ had the issue of not
expecting a type to doing something within it's tp_str implementation that
could trigger an infinite recursion, but it could in C code..  Both found
thanks to BaseException and how it handles its repr.

Closes issue #1686386.  Thanks to Thomas Herve for taking an initial stab at
coming up with a solution.

Change to LogRecord.__init__() to fix #1206. Note that archaic use of type(x) == types.DictType is because of keeping 1.5.2 compatibility. While this is much less relevant these days, there probably needs to be a separate commit for removing all archaic constructs at the same time.

Make tell() mark CRLF as a newline.

Try harder to stay within the 79-column limit. There's still two places that go (way) over, but those are harder to fix without suffering in readability.

predictable to being completely predictable.  The value of hash(n)
is unchanged for any n that's small enough to be representable as an
int, and also unchanged for the vast majority of long integers n of
reasonable size.

Added a bit of testing for this.
