- make the selftests work again (they were apparently not used since
very early in bgen's development), with some minor cleanup by me
- make emacs python mode happier
PyString_FromFormatV(): In the final resize at the end, we can use
PyString_AS_STRING() since we know the object is a string and can
avoid the typechecking.
PyString_FromFormat(): GS sez: "For safety/propriety, you should call
va_end() on the vargs variable."
at least in the first two characters. %p is ill-defined, and people will
forever commit bad tests otherwise ("bad" in the sense that they fall
over (at least on Windows) for lack of a leading '0x'; 5 of the 7 tests
in test_repr.py failed on Windows for that reason this time around).
recent classobject.c change. When calling an unbound method with no
instances as first argument, the error message has changed. The
message now contains the class name, but the output text being
compared to is too generic, so skip printing it.
an inappropriate first argument. Now that there are more ways for
this to fail, make sure to report the name of the class of the
expected instance and of the actual instance.
lambda (anonymous functions?), function, xrange, buffer, cell (need to
fill in), and (some) descriptor types.
Also added a new test case for testing repr truncation fixes.
PyErr_Format() these new C API methods can be used instead of
sprintf()'s into hardcoded char* buffers. This allows us to fix
many situation where long package, module, or class names get
truncated in reprs.
PyString_FromFormat() is the varargs variety.
PyString_FromFormatV() is the va_list variety
Original PyErr_Format() code was modified to allow %p and %ld
expansions.
Many reprs were converted to this, checkins coming soo. Not
changed: complex_repr(), float_repr(), float_print(), float_str(),
int_repr(). There may be other candidates not yet converted.
Closes patch #454743.
super(type) -> unbound super object
super(type, obj) -> bound super object; requires isinstance(obj, type)
Typical use to call a cooperative superclass method:
class C(B):
def meth(self, arg):
super(C, self).meth(arg);
the delete function. (Question: should the attribute name also be
recorded in the getset object? That makes the protocol more work, but
may give us better error messages.)

powu: Deleted.
This started with a nonsensical error msg:
>>> x = -1.
>>> import sys
>>> x**(-sys.maxint-1L)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ValueError: negative number cannot be raised to a fractional power

The special-casing in float_pow was simply wrong in this case (there's
not even anything peculiar about these inputs), and I don't see any point
to it in *any* case: a decent libm pow should have worst-case error under
1 ULP, so in particular should deliver the exact result whenever the exact
result is representable (else its error is at least 1 ULP). Thus our
special fiddling for integral values "shouldn't" buy anything in accuracy,
and, to the contrary, repeated multiplication is less accurate than a
decent pow when the true result isn't exactly representable. So just
letting pow() do its job here (we may not be able to trust libm x-platform
in exceptional cases, but these are normal cases).
