Tim Peters 7a50f2536e More for SF bug [#460020] bug or feature: unicode() and subclasses
Repair float constructor to return a true float when passed a subclass
instance.  New PyFloat_CheckExact macro.

Tim Peters 64b5ce3a69 SF bug #460020: bug or feature: unicode() and subclasses.
Given an immutable type M, and an instance I of a subclass of M, the
constructor call M(I) was just returning I as-is; but it should return a
new instance of M.  This fixes it for M in {int, long}.  Strings, floats
and tuples remain to be done.
Added new macros PyInt_CheckExact and PyLong_CheckExact, to more easily
distinguish between "is" and "is a" (i.e., only an int passes
PyInt_CheckExact, while any sublass of int passes PyInt_Check).
Added private API function _PyLong_Copy.

Tim Peters 37a309db70 builtin_dir(): Treat classic classes like types. Use PyDict_Keys instead
of PyMapping_Keys because we know we have a real dict.  Tolerate that
objects may have an attr named "__dict__" that's not a dict (Py_None
popped up during testing).

test_descr.py, test_dir():  Test the new classic-class behavior; beef up
the new-style class test similarly.

test_pyclbr.py, checkModule():  dir(C) is no longer a synonym for
C.__dict__.keys() when C is a classic class (looks like the same thing
that burned distutils! -- should it be *made* a synoym again?  Then it
would be inconsistent with new-style class behavior.).

Tim Peters 5d2b77cf31 Make dir() wordier (see the new docstring). The new behavior is a mixed
bag.  It's clearly wrong for classic classes, at heart because a classic
class doesn't have a __class__ attribute, and I'm unclear on whether
that's feature or bug.  I'll repair this once I find out (in the
meantime, dir() applied to classic classes won't find the base classes,
while dir() applied to a classic-class instance *will* find the base
classes but not *their* base classes).

Please give the new dir() a try and see whether you love it or hate it.
The new dir([]) behavior is something I could come to love.  Here's
something to hate:

>>> class C:
...     pass
...
>>> c = C()
>>> dir(c)
['__doc__', '__module__']
>>>

The idea that an instance has a __doc__ attribute is jarring (of course
it's really c.__class__.__doc__ == C.__doc__; likewise for __module__).

OTOH, the code already has too many special cases, and dir(x) doesn't
have a compelling or clear purpose when x isn't a module.

Tim Peters 25786c0851 Make dictionary() a real constructor. Accepts at most one argument, "a
mapping object", in the same sense dict.update(x) requires of x (that x
has a keys() method and a getitem).
Questionable:  The other type constructors accept a keyword argument, so I
did that here too (e.g., dictionary(mapping={1:2}) works).  But type_call
doesn't pass the keyword args to the tp_new slot (it passes NULL), it only
passes them to the tp_init slot, so getting at them required adding a
tp_init slot to dicts.  Looks like that makes the normal case (i.e., no
args at all) a little slower (the time it takes to call dict.tp_init and
have it figure out there's nothing to do).

Guido van Rossum 91ee798892 metaclass(): add some more examples of metaclasses, including one
using cooperative multiple inheritance.

inherits(): add a test for subclassing the unicode type.
2001-08-30 20:52:40 +00:00
Guido van Rossum caa9f43779 Add testcases for inheritance from tricky builtins (numbers, strings,
tuples).
2001-08-30 20:06:08 +00:00
Guido van Rossum 8aea0cc94e Now that int is subclassable, have to change a test that tests for
non-subclassability.  (More tests for number subclassing should follow.)

Guido van Rossum 84a79a8d25 classic(),metods(): add tests to verify that a bound method without a
class has a correct repr().
2001-08-17 13:58:31 +00:00
Guido van Rossum 93018760bc classic(), methods(): add another test relating to unbound methods:
when an unbound method of class A is stored as a class variable of
class B, and class B is *not* a subclass of class A, that method
should *not* get bound to B instances.
2001-08-17 13:40:47 +00:00

Guido van Rossum 309b566704 metaclass(): add tests for metaclasses written in Python: one that
subclasses type, one that doesn't (the latter isn't fully functional
yet).
2001-08-17 11:43:17 +00:00
Guido van Rossum 501c7c7d0e classobject.c:instancemethod_descr_get(): when a bound method is
assigned to a class variable and then accessed via an instance, it
should not be rebound.

test_descr.py:methods(): test for the condition above.

Tim Peters 4d2dded044 test_descr started breaking in yet another way in the same place. 2001-08-16 19:50:51 +00:00
Tim Peters 63a8d69476 Repair some accidents causing Windows failures:
+ test_compare.  While None compares less than anything else, it's not
  always the case that None has the smallest id().
+ test_descr.  The output of %p (pointer) formats varies across platforms.
  In particular, on Windows it doesn't produce a leading "0x".

Guido van Rossum a4ff6ab093 Add tests for overridable operators that have default interpretations
(__hash__ etc.), in static and dynamic classes, overridden and
default.
2001-08-15 23:57:59 +00:00
Guido van Rossum b5a136b05d Add a test to verify that bound methods work correctly. 2001-08-15 17:51:17 +00:00
Guido van Rossum 80e36750c8 Add a test for a weird bug I just discovered: a dynamic subclass
doesn't have a __dict__!
2001-08-14 20:00:33 +00:00
Guido van Rossum d3077402c7 - Expand test for dynamic objects.
- Remove various 'global' directives and move some global definitions
  inside the test functions that use them -- we have nested scopes so
  the old hacks using globals are no longer needed.

Guido van Rossum 9d4fe4298e dynamics(): add tests for dynamic *instances* (which are currently
broken).  Also fix an invalid reference to C (should be S).

Guido van Rossum e45763a8e6 Add test for SF bug #442833 (multiple inheritance). 2001-08-10 21:28:46 +00:00

Guido van Rossum 3720261729 Restore the test for 'object' that I removed when object was
uninstantiable.  All is well now.
2001-08-09 19:45:21 +00:00
Guido van Rossum 15d86c6297 Remove the test for the 'object' type -- it can no longer be
instantiated.  (Its use as a base class is adequately tested by other
tests.)
