d4ba73c75b Move the definition of PyMethodObject to classobject.h, so it can define
macros for more efficient access to the fields.

7859f87fdb Marc-Andre Lemburg's patch to support instance methods with other
callable objects than regular Pythonm functions as their im_func.

a63eff6e6a Allow assignments to special class attributes -- with typechecks, and
not in restricted mode.

__dict__ can be set to any dictionary; the cl_getattr, cl_setattr and
cl_delattr slots are refreshed.

__name__ can be set to any string.

__bases__ can be set to to a tuple of classes, provided they are not
subclasses of the class whose attribute is being assigned.

__getattr__, __setattr__ and __delattr__ can be set to anything, or
deleted; the appropriate slot (cl_getattr, cl_setattr, cl_delattr) is
refreshed.

(Note: __name__ really doesn't need to be a special attribute, but
that would be more work.)

like <modulename.classname instance at ...> (to match the repr() of
class objects.

3931df9250 Undo another glitch of the automatic not-so-Grand Renaming; some local
variables called 'coerce' were accidentally renamed to
'PyNumber_Coerce'.  Rename them back to coercefunc.

4a2a621907 Write a str() function for class objects that returns
"modulename.classname" instead of returning the same as repr().

04d73c495e Check that all base classes are indeed class objects, rather than
expecting the caller to do so.

7cc56eb524 When creating a class, set its __module__ attribute to the module
whose name is in the current globals' __name__ variable.  If __name__
is not set, ignore this.

b2173c3146 Allow assignments to instance.__dict__ and instance.__class__. The
former lets you give an instance a set of new instance vars.  The
latter lets you give it a new class.  Both are typechecked and
disallowed in restricted mode.

For classes, the check for read-only special attributes is tightened
so that only assignments to __dict__, __bases__, __name__,
__getattr__, __setattr__, and __delattr__ (these could be made to work
as well, but I don't know if that's useful -- let's see first whether
mucking with instances will help).

a0d349f46a Added separate free list for instance method objects, for a few
percent speed up.  Also add PyMethod_Fini() to discard it.

6dabc98400 Added __name__ attribute to class instance method objects.
Removed im_doc attribute; __name__ and __doc__ are now handled by
special casing in instancemethodgetattr().  This saves a few bytes and
INCREF/DECREF calls per i.m. object allocation/deallocation.

e7d444f785 * Objects/classobject.c: added 5th (function) parameter to

03093a248d * Include/classobject.h, Objects/classobject.c, Python/ceval.c:
entirely redone operator overloading.  The rules for class
	instances are now much more relaxed than for other built-in types
	(whose coerce must still return two objects of the same type)

	* Objects/floatobject.c: add overflow check when converting float
	to int and implement truncation towards zero using ceil/float

	* Objects/longobject.c: change ValueError to OverflowError when
	converting to int

	* Objects/rangeobject.c: modernized

	* Objects/stringobject.c: use HAVE_LIMITS instead of __STDC__

	* Objects/xxobject.c: changed to use new style (not finished?)

91ab4a8353 If an attribute is deleted, __setattr__ is called with 2 instead of 3
arguments (adding __delattr__ was deemed too much overhead)
1994-08-16 22:13:47 +00:00
Guido van Rossum
e149fa2a1e * Objects/classobject.c, Include/classobject.h: added __getattr__
and __setattr__ support to override getattr(x, name) and
	setattr(x, name, value) for class instances.  This uses a special
	hack whereby the class is supposed to be static: the __getattr__
	and __setattr__ methods are looked up only once and saved in the
	instance structure for speed
