c922bfa4cd Net result of Guido's checkins of object.c (2.125 and 2.126), classobject.c
(2.128) and stringobject.c (2.105), which reworks PyObject_Str() and
PyObject_Repr() so strings and instances aren't special-cased, and
    print >> file, instance
works like expected in all cases.

db81e8ddf8 Add support for weak references to the function and method types. 2001-03-23 04:19:27 +00:00
Fred Drake
4e262a9631 A small change to the C API for weakly-referencable types: Such types
must now initialize the extra field used by the weak-ref machinery to
NULL themselves, to avoid having to require PyObject_INIT() to check
if the type supports weak references and do it there.  This causes less
work to be done for all objects (the type object does not need to be
consulted to check for the Py_TPFLAGS_HAVE_WEAKREFS bit).

b60654bc15 The return value from PyObject_ClearWeakRefs() is no longer meaningful,
so make it void.

4f9b13bac8 instancemethod_setattro(): Raise TypeError if an attempt is made to
set a function attribute on a method (either bound or unbound).  This
reverts to Python 2.0 behavior that no attributes of the method are
writable, but provides a more informative error message.

3202c6fac8 Rename dubiously named local variable 'cmpfunc' -- this is also a
typedef, and at least one compiler choked on this.

65e8bd7fd5 Rich comparisons fallout: instance_hash() should check for both
__cmp__ and __eq__ absent before deciding to do a quickie
based on the object address.  (Tim Peters discovered this.)

24f67d568c Fix a leak in instance_coerce(). This was introduced by Neil's
earlier coercion changes, not by rich comparisons.  When a coercion
function returns 1 (meaning it cannot do it), it should not INCREF the
arguments.  When no __coerce__() method was found, instance_coerce()
originally returned 0, pretending it did it.  Neil changed the return
value to 1, more accurately reflecting that it didn't do anything, but
forgot to take out the two INCREF calls.

8998b4f691 Rich comparisons.
- Got rid of instance_cmp(); refactored instance_compare().

- Added instance_richcompare() which calls __lt__() etc.

Some unrelated stuff mixed in:

- Aligned comments in various large struct initializers.

- Better test to avoid recursion if __coerce__ returns self as the
  first argument (this is an unrelated fix by Neil Schemenauer!).

- Style nit: don't use Py_DECREF(Py_NotImplemented); use
  Py_DECREF(result) -- it just looks better. :-)

d6a9e84c81 Committing PEP 232, function attribute feature, approved by Guido.
Closes SF patch #103123.

funcobject.h:

    PyFunctionObject: add the func_dict slot.

funcobject.c:

    PyFunction_New(): Initialize the func_dict slot to NULL.

    func_getattr(): Rename to func_getattro() and change the
    signature.  It's more efficient to use attro methods and dig the C
    string out than it is to re-convert a C string to a PyString.

    Also, add support for getting the __dict__ (a.k.a. func_dict)
    attribute, and for getting an arbitrary function attribute.

    func_setattr(): Rename to func_setattro() and change the signature
    for the same reason.  Also add support for setting __dict__
    (a.k.a. func_dict) and any arbitrary function attribute.

    func_dealloc(): Be sure to DECREF the func_dict slot.

    func_traverse(): Be sure to traverse func_dict too.

    PyFunction_Type: make the necessary func_?etattro() changes.

classobject.c:

    instancemethod_memberlist: Add __dict__

    instancemethod_setattro(): New method to set arbitrary attributes
    on methods (really the underlying im_func).  Raise TypeError when
    the instance is bound or when you're trying to set one of the
    reserved im_* attributes.

    instancemethod_getattr(): Renamed to instancemethod_getattro()
    since that's what it really is.  Also, added support fo getting
    arbitrary attributes through the im_func.

    PyMethod_Type: Do the ?etattr{,o} dance.

29bfc07183 Make instances a new style number type. See PEP 208 for details. Instance
types no longer get special treatment from abstract.c so more number number
methods have to be implemented.

6b184918f6 Fix for SF bug 110688: Instance deallocation neglected to account for
that Py_INCREF boosts global _Py_RefTotal when Py_REF_DEBUG is defined
but Py_TRACE_REFS isn't.

There are, IMO, way too many preprocessor gimmicks in use for refcount
debugging (at least 3 distinct true/false symbols, but not all 8 combos
are supported by the code, etc etc), and no coherent documentation of
this stuff -- 'twas too painful to track this one down.

b709df3810 refactor __del__ exception handler into PyErr_WriteUnraisable
add sanity check to gc: if an exception occurs during GC, call
PyErr_WriteUnraisable and then call Py_FatalEror.

e289e0bd0c Support for the in-place operations introduced by augmented assignment. Only
the list object supports this currently, but other candidates are
gladly accepted (like arraymodule and such.)

dc55d715bb PyInstance_DoBinOp(): When comparing the pointers, they must be cast
to integer types (i.e. Py_uintptr_t, our spelling of C9X's uintptr_t).
ANSI specifies that pointer compares other than == and != to
non-related structures are undefined.  This quiets an Insure
portability warning.

1d75a79c00 Apply SF patch #101029: call __getitem__ with a proper slice object if there
is no __getslice__ available. Also does the same for C extension types.
Includes rudimentary documentation (it could use a cross reference to the
section on slice objects, I couldn't figure out how to do that) and a test
suite for all Python __hooks__ I could think of, including the new
behaviour.
