try to explain the complex general scheme we actually use now, I decided
to spell out only what equality means (which is easy to explain and
intuitive), leaving the other outcomes unspecified beyond consistency.
The patch repaired internal gcc compiler errors on BeOS.
This checkin repairs them in a simpler way, by explicitly casting the
platform INFINITY to double.
- SLOT1BINFULL() macro: changed this to check for __rop__ overriding
__op__, like binary_op1() in abstract.c -- the latter only calls the
slot function once if both types use the same slot function, so the
slot function must make both calls -- which it already did for the
__op__, __rop__ order, but not yet for the __rop__, __op__ order
when B.__class__ is a subclass of A.__class__.
- slot_sq_contains(), slot_nb_nonzero(): use lookup_maybe() rather
than lookup_method() which sets an exception which we then clear.
- slot_nb_coerce(): don't give up when left argument's __coerce__
returns NotImplemented, but give the right argument a chance.
as container objects rather than as mapping objects (in the index entries).
Change the section heading and intro sentence to be a little more general,
since that's how things have actually evolved.
I modified nntplib so the body method can accept an
optional second parameter pointing to a filehandle or
filename (string). This way, really long body
articles can be stored to disk instead of kept in
memory. The way I made the modification should make
it easy to extend this functionality to other extended
return methods.
Generalize PyLong_AsLongLong to accept int arguments too. The real point
is so that PyArg_ParseTuple's 'L' code does too. That code was
undocumented (AFAICT), so documented it.
This is probably a little bit faster, but mostly is just cleaner code.
The old-style support is still used for Python versions < 2.2 so this
source file can be shared with PyXML.
staticness when __dynamic__ = 1 becomes the default:
- Some classes which are used to test the difference between static
and dynamic.
- Subclasses of complex: complex uses old-style numbers and the slot
wrappers used by dynamic classes only support new-style numbers.
(Ideally, the complex type should be fixed, but that looks like a
labor-intensive job.)
__rop__ now takes precendence over __op__. Those circumstances are:
- Both arguments are new-style classes
- Both arguments are new-style numbers
- Their implementation slots for tp_op differ
- Their types differ
- The right argument's type is a subtype of the left argument's type
Also did this for the ternary operator (pow) -- only the binary case
is dealt with properly though, since __rpow__ is not supported anyway.
