Tim Peters a427a2b8d0 Rename "dictionary" (type and constructor) to "dict". 2001-10-29 22:25:45 +00:00
Tim Peters 4d85953fe6 dictionary() constructor:
+ Change keyword arg name from "x" to "items".  People passing a mapping
  object can stretch their imaginations <wink>.
+ Simplify the docstring text.
2001-10-27 18:27:48 +00:00
Tim Peters 9fda73cdd1 dict_constructor(): The last test was passing for the wrong reason (it
was intended to verify that sub-sequences of lengths 1 and 3 raise
ValueError, but was actually testing string lengths).
2001-10-26 20:57:38 +00:00
Tim Peters 1fc240e851 Generalize dictionary() to accept a sequence of 2-sequences. At the
outer level, the iterator protocol is used for memory-efficiency (the
outer sequence may be very large if fully materialized); at the inner
level, PySequence_Fast() is used for time-efficiency (these should
always be sequences of length 2).

dictobject.c, new functions PyDict_{Merge,Update}FromSeq2.  These are
wholly analogous to PyDict_{Merge,Update}, but process a sequence-of-2-
sequences argument instead of a mapping object.  For now, I left these
functions file static, so no corresponding doc changes.  It's tempting
to change dict.update() to allow a sequence-of-2-seqs argument too.

Also changed the name of dictionary's keyword argument from "mapping"
to "x".  Got a better name?  "mapping_or_sequence_of_pairs" isn't
attractive, although more so than "mosop" <wink>.

abstract.h, abstract.tex:  Added new PySequence_Fast_GET_SIZE function,
much faster than going thru the all-purpose PySequence_Size.

libfuncs.tex:
- Document dictionary().
- Fiddle tuple() and list() to admit that their argument is optional.
- The long-winded repetitions of "a sequence, a container that supports
  iteration, or an iterator object" is getting to be a PITA.  Many
  months ago I suggested factoring this out into "iterable object",
  where the definition of that could include being explicit about
  generators too (as is, I'm not sure a reader outside of PythonLabs
  could guess that "an iterator object" includes a generator call).
- Please check my curly braces -- I'm going blind <0.9 wink>.

abstract.c, PySequence_Tuple():  When PyObject_GetIter() fails, leave
its error msg alone now (the msg it produces has improved since
PySequence_Tuple was generalized to accept iterable objects, and
PySequence_Tuple was also stomping on the msg in cases it shouldn't
have even before PyObject_GetIter grew a better msg).

Guido van Rossum 6661be3bed Allow assignment to newinstance.__dict__. 2001-10-26 04:26:12 +00:00
Fred Drake 4bf018b138 Fixed denial-of-weak-ref-support test; Jeremy changed the error message
used by the weakref code since he didn't like the word "referencable".
Is it really necessary to be more specific than to test for TypeError here,
though?
2001-10-22 21:45:25 +00:00
Guido van Rossum c8e5645f15 Methods of built-in types now properly check for keyword arguments
(formerly these were silently ignored).  The only built-in methods
that take keyword arguments are __call__, __init__ and __new__.
2001-10-22 00:43:43 +00:00
Guido van Rossum f76de62f7d Fix SF bug #472234: type(obj) calls type->tp_init (Roeland Rengelink)
The fix is a band-aid: type_call() now makes the same exception for a
single-argument call to type() as type_new() was already making.
2001-10-18 15:49:21 +00:00
Tim Peters c993315b18 SF bug [#468061] __str__ ignored in str subclass.
object.c, PyObject_Str:  Don't try to optimize anything except exact
string objects here; in particular, let str subclasses go thru tp_str,
same as non-str objects.  This allows overrides of tp_str to take
effect.

stringobject.c:
+ string_print (str's tp_print):  If the argument isn't an exact string
  object, get one from PyObject_Str.

+ string_str (str's tp_str):  Make a genuine-string copy of the object if
  it's of a proper str subclass type.  str() applied to a str subclass
  that doesn't override __str__ ends up here.

test_descr.py:  New str_of_str_subclass() test.
2001-10-16 20:18:24 +00:00
Guido van Rossum 2f3ca6eeb6 Completely get rid of __dynamic__ and the corresponding
Py_TPFLAGS_DYNAMICTYPE bit.  There is no longer a performance benefit,
and I don't really see the use case any more.
2001-10-15 21:05:10 +00:00
Tim Peters fc57ccb982 SF bug [#470040] ParseTuple t# vs subclasses.
inherit_slots():  tp_as_buffer was getting inherited as if it were a
method pointer, rather than a pointer to a vector of method pointers.  As
a result, inheriting from a type that implemented buffer methods was
ineffective, leaving all the tp_as_buffer slots NULL in the subclass.
2001-10-12 02:38:24 +00:00
Guido van Rossum 875eeaa193 Another step in the right direction: when a new class's attribute
corresponding to a dispatch slot (e.g. __getitem__ or __add__) is set,
calculate the proper dispatch slot and propagate the change to all
subclasses.  Because of multiple inheritance, there's no easy way to
avoid always recursing down the tree of subclasses.  Who cares?

(There's more to do, but this works.  There's also a test for this now.)
2001-10-11 18:33:53 +00:00
Guido van Rossum 12b22ff6d7 Add a bunch of tests for a list subclass that would have caught the
previous embarrassment (typeobject.c checking crashing minidom).
2001-10-09 20:36:44 +00:00
Guido van Rossum 0eb2a6e974 It turned out not so difficult to support old-style numbers (those
without the Py_TPFLAGS_CHECKTYPES flag) in the wrappers.  This
required a few changes in test_descr.py to cope with the fact that the
complex type has __int__, __long__ and __float__ methods that always
raise an exception.
2001-10-09 11:07:24 +00:00
Guido van Rossum 4570455813 Change all occurrences of verify(x == y) into vereq(x, y), since when
this type of test fails, vereq() does a better job of reporting than
verify().

Change vereq(x, y) to use "not x == y" rather than "x != y" -- it
makes a difference is some overloading tests.
2001-10-08 16:35:45 +00:00
Tim Peters 4fb1fe8bd2 class_docstrings(): The new-style class tests should use new-style
classes (sheesh!).
2001-10-04 05:48:13 +00:00
Tim Peters 2f93e28a19 SF bug [#467331] ClassType.__doc__ always None.
For a dynamically constructed type object, fill in the tp_doc slot with
a copy of the argument dict's "__doc__" value, provided the latter exists
and is a string.
NOTE:  I don't know what to do if it's a Unicode string, so in that case
tp_doc is left NULL (which shows up as Py_None if you do Class.__doc__).
Note that tp_doc holds a char*, not a general PyObject*.
2001-10-04 05:27:00 +00:00
Guido van Rossum 4a5a2bc2b6 dynamics(): add a dummy __getattr__ method to the C class so that the
test for modifying __getattr__ works, now that slot_tp_getattr_hook
zaps the slot if there's no hook.  Added an XXX comment with a ref
back to slot_tp_getattr_hook.
2001-10-03 13:59:54 +00:00
Guido van Rossum fe1fd0e6e9 pickles():
- The test for deepcopy() in pickles() was indented wrongly, so it got
  run twice (one for binary pickle mode, one for text pickle mode; but
  the test doesn't depend on the pickle mode).

- In verbose mode, show which subtest (pickle/cPickle/deepcopy, text/bin).
2001-10-02 19:58:32 +00:00
Guido van Rossum 751c4c864c Add a few ``__dynamic__ = 0'' lines in classes that need to preserve
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.)
2001-09-29 00:40:25 +00:00
Guido van Rossum 4bb1e36eec It's a fact: for binary operators, *under certain circumstances*,
__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.
2001-09-28 23:49:48 +00:00
Guido van Rossum 6cef6d5d62 Changes to copy() and deepcopy() in copy.py to support __reduce__ as a
fallback for objects that are neither supported by our dispatch table
nor have a __copy__ or __deepcopy__ method.

Changes to _reduce() in copy_reg.py to support reducing objects that
don't have a __dict__ -- copy.copy(complex()) now invokes _reduce().

Add tests for copy.copy() and copy.deepcopy() to test_regrtest.py.
2001-09-28 18:13:29 +00:00
Guido van Rossum 3926a63d05 - Provisional support for pickling new-style objects. (*)
- Made cls.__module__ writable.

- Ensure that obj.__dict__ is returned as {}, not None, even upon first
  reference; it simply springs into life when you ask for it.

(*) The pickling support is provisional for the following reasons:

- It doesn't support classes with __slots__.

- It relies on additional support in copy_reg.py: the C method
  __reduce__, defined in the object class, really calls calling
  copy_reg._reduce(obj).  Eventually the Python code in copy_reg.py
  needs to be migrated to C, but I'd like to experiment with the
  Python implementation first.  The _reduce() code also relies on an
  additional helper function, _reconstructor(), defined in
  copy_reg.py; this should also be reimplemented in C.
2001-09-25 16:25:58 +00:00
Guido van Rossum 5c294fb0e6 Make __class__ assignment possible, when the object structures are the
same.  I hope the test for structural equivalence is stringent enough.
It only allows the assignment if the old and new types:

- have the same basic size
- have the same item size
- have the same dict offset
- have the same weaklist offset
- have the same GC flag bit
- have a common base that is the same except for maybe the dict and
  weaklist (which may have been added separately at the same offsets
  in both types)
2001-09-25 03:43:42 +00:00
Tim Peters 66c1a525e0 Make properties discoverable from Python:
- property() now takes 4 keyword arguments:  fget, fset, fdel, doc.
  Note that the real purpose of the 'f' prefix is to make fdel fit in
  ('del' is a keyword, so can't used as a keyword argument name).

- These map to visible readonly attributes 'fget', 'fset', 'fdel',
  and '__doc__' in the property object.

- fget/fset/fdel weren't discoverable from Python before.

- __doc__ is new, and allows to associate a docstring with a property.
2001-09-24 21:17:50 +00:00
Guido van Rossum 3d45d8f12e Another comparison patch-up: comparing a type with a dynamic metatype
to one with a static metatype raised an obscure error.
2001-09-24 18:47:40 +00:00
Guido van Rossum 2205642fe0 Do the same thing to complex that I did to str: the rich comparison
function returns NotImplemented when comparing objects whose
tp_richcompare slot is not itself.
2001-09-24 17:52:04 +00:00
Guido van Rossum bb77e6801e Change string comparison so that it applies even when one (or both)
arguments are subclasses of str, as long as they don't override rich
comparison.
2001-09-24 16:51:54 +00:00
Guido van Rossum ff0e6d6ef5 Fix the baffler that Tim reported: sometimes the repr() of an object
looks like <X object at ...>, sometimes it says <X instance at ...>.
Make this uniformly say <X object at ...>.
2001-09-24 16:03:59 +00:00
Guido van Rossum 19c1cd5b35 Add the __getattr__ hook back. The rules are now:
- if __getattribute__ exists, it is called first;
  if it doesn't exists, PyObject_GenericGetAttr is called first.
- if the above raises AttributeError, and __getattr__ exists,
  it is called.
2001-09-21 21:24:49 +00:00
Guido van Rossum 867a8d2e26 Change the name of the __getattr__ special method for new-style
classes to __getattribute__, to make it crystal-clear that it doesn't
have the same semantics as overriding __getattr__ on classic classes.

This is a halfway checkin -- I'll proceed to add a __getattr__ hook
that works the way it works in classic classes.
2001-09-21 19:29:08 +00:00
Guido van Rossum 8b9cc7e69e Add a small test to verify that member and getset descriptors now have
docstrings (using file.closed and file.name as examples).
2001-09-20 21:49:53 +00:00
Guido van Rossum a56b42b1ba Change testdescr.py to use the test_main() approach. 2001-09-20 21:39:07 +00:00
Guido van Rossum 1952e388ca Add additional coercion support for "self subtypes" to int, long,
float (compare the recent checkin to complex).  Added tests for these.
2001-09-19 01:25:16 +00:00
Guido van Rossum d5d8e4a436 Enable two checks for comparing a complex to a complex subtype
instance.

Split a string comparison test in two halves, replacing "a==b==a" with
separate tests for a==b and b==a.  (Reason: while experimenting, this
test failed, and I wanted to know if it was the first or the second ==
operator that failed.)
2001-09-19 01:16:16 +00:00
Tim Peters 50fda6c21f Enable some comparison tests that failed before. Still having problems
with subsclasses of complex and string.
2001-09-18 21:24:18 +00:00
Guido van Rossum 0639f59859 Add a similar test for rich comparisons. 2001-09-18 21:06:04 +00:00
Guido van Rossum ab3b0343b8 Hopefully fix 3-way comparisons. This unfortunately adds yet another
hack, and it's even more disgusting than a PyInstance_Check() call.
If the tp_compare slot is the slot used for overrides in Python,
it's always called.

Add some tests that show what should work too.
2001-09-18 20:38:53 +00:00
Guido van Rossum 843daa8cad Test for the safety check in wrap_cmpfunc(). 2001-09-18 20:04:26 +00:00
Tim Peters 305b5857f6 PyObject_Dir(): Merge in __members__ and __methods__ too (if they exist,
and are lists, and then just the string elements (if any)).

There are good and bad reasons for this.  The good reason is to support
dir() "like before" on objects of extension types that haven't migrated
to the class introspection API yet.  The bad reason is that Python's own
method objects are such a type, and this is the quickest way to get their
im_self etc attrs to "show up" via dir().  It looks much messier to move
them to the new scheme, as their current getattr implementation presents
a view of their attrs that's a untion of their own attrs plus their
im_func's attrs.  In particular, methodobject.__dict__ actually returns
methodobject.im_func.__dict__, and if that's important to preserve it
doesn't seem to fit the class introspection model at all.
2001-09-17 02:38:46 +00:00
Tim Peters e0007821cd Since we had a bug with multiplication of dynamic long subclasses, add a
little test to make sure it doesn't come back.
2001-09-15 06:35:55 +00:00
Guido van Rossum 7e35d57c0c A fix for SF bug #461546 (bug in long_mul).
Both int and long multiplication are changed to be more careful in
their assumptions about when one of the arguments is a sequence: the
assumption that at least one of the arguments must be an int (or long,
respectively) is still held, but the assumption that these don't smell
like sequences is no longer true: a subtype of int or long may well
have a sequence-repeat thingie!
2001-09-15 03:14:32 +00:00
Tim Peters 0ab085c4cb Changed the dict implementation to take "string shortcuts" only when
keys are true strings -- no subclasses need apply.  This may be debatable.

The problem is that a str subclass may very well want to override __eq__
and/or __hash__ (see the new example of case-insensitive strings in
test_descr), but go-fast shortcuts for strings are ubiquitous in our dicts
(and subclass overrides aren't even looked for then).  Another go-fast
reason for the change is that PyCheck_StringExact() is a quicker test
than PyCheck_String(), and we make such a test on virtually every access
to every dict.

OTOH, a str subclass may also be perfectly happy using the base str eq
and hash, and this change slows them a lot.  But those cases are still
hypothetical, while Python's own reliance on true-string dicts is not.
2001-09-14 00:25:33 +00:00
Tim Peters 8fa45677c1 Now that file objects are subclassable, you can get at the file constructor
just by doing type(f) where f is any file object.  This left a hole in
restricted execution mode that rexec.py can't plug by itself (although it
can plug part of it; the rest is plugged in fileobject.c now).
2001-09-13 21:01:29 +00:00
Tim Peters 561f899d19 Use the keyword form of file() instead of open() to create TESTFN. 2001-09-13 19:36:36 +00:00
Tim Peters 808b94eb45 Added simple tests of keyword arguments in the basic type constructors. 2001-09-13 19:33:07 +00:00
Tim Peters 3f996e7266 type_call(): Change in policy. The keyword args (if any) are now passed
on to the tp_new slot (if non-NULL), as well as to the tp_init slot (if
any).  A sane type implementing both tp_new and tp_init should probably
pay attention to the arguments in only one of them.
2001-09-13 19:18:27 +00:00
Tim Peters 59c9a645e2 SF bug [#460467] file objects should be subclassable.
Preliminary support.  What's here works, but needs fine-tuning.
2001-09-13 05:38:56 +00:00
Tim Peters 4f467e8057 Added subclass equality tests. Almost all of these are commented out now,
because they don't work yet.
2001-09-12 19:53:15 +00:00
Tim Peters 2400fa4ad1 Again perhaps the end of [#460020] bug or feature: unicode() and subclasses.
Inhibited complex unary plus optimization when applied to a complex subtype.
Added PyComplex_CheckExact macro.  Some comments and minor code fiddling.
2001-09-12 19:12:49 +00:00
Tim Peters 111f60964e If interning an instance of a string subclass, intern a real string object
with the same value instead.  This ensures that a string (or string
subclass) object's ob_sinterned pointer is always a str (or NULL), and
that the dict of interned strings only has strs as keys.
2001-09-12 07:54:51 +00:00
Tim Peters af90b3e610 str_subtype_new, unicode_subtype_new:
+ These were leaving the hash fields at 0, which all string and unicode
  routines believe is a legitimate hash code.  As a result, hash() applied
  to str and unicode subclass instances always returned 0, which in turn
  confused dict operations, etc.
+ Changed local names "new"; no point to antagonizing C++ compilers.
2001-09-12 05:18:58 +00:00
Tim Peters 7a29bd5861 More on bug 460020: disable many optimizations of unicode subclasses. 2001-09-12 03:03:31 +00:00
Tim Peters 8fa5dd0601 More bug 460020: lots of string optimizations inhibited for string
subclasses, all "the usual" ones (slicing etc), plus replace, translate,
ljust, rjust, center and strip.  I don't know how to be sure they've all
been caught.

Question:  Should we complain if someone tries to intern an instance of
a string subclass?  I hate to slow any code on those paths.
2001-09-12 02:18:30 +00:00
Tim Peters 69c2de3ad6 More bug 460020. Disable a number of long optimizations for long subclasses. 2001-09-11 22:31:33 +00:00
Tim Peters 0280cf79a7 More bug 460020: when F is a subclass of float, disable the unary plus
optimization (+F(whatever)).
2001-09-11 21:53:35 +00:00
Tim Peters 73a1dfe367 More bug 460020. When I is a subclass of int, disable the +I(whatever),
I(0) << whatever, I(0) >> whatever, I(whatever) << 0 and I(whatever) >> 0
optimizations.
2001-09-11 21:44:14 +00:00
Tim Peters 7b07a41e9f The endless 460020 bug.
Disable t[:], t*0, t*1 optimizations when t is of a tuple subclass type.
2001-09-11 19:48:03 +00:00
Guido van Rossum 779ce4a73a Restore the comparisons that I initially put in the test but that Tim
XXX'ed out.  Turns out that after fixing the constructors, the
comparisons in fact succeed.  E.g. int(hexint(12345)) returns an int
with value 12345.
2001-09-11 14:02:22 +00:00
Tim Peters 78e0fc74bc Possibly the end of SF [#460020] bug or feature: unicode() and subclasses.
Changed unicode(i) to return a true Unicode object when i is an instance of
a unicode subclass.  Added PyUnicode_CheckExact macro.
2001-09-11 03:07:38 +00:00
Tim Peters c636f565b4 Added another test of str() applied to a string subclass instance,
involving embedded null bytes, since it's possible to screw that up w/o
screwing up cases w/o embedded nulls.
2001-09-11 01:52:02 +00:00
Tim Peters 5a49ade70e More on SF bug [#460020] bug or feature: unicode() and subclasses.
Repaired str(i) to return a genuine string when i is an instance of a str
subclass.  New PyString_CheckExact() macro.
2001-09-11 01:41:59 +00:00
Tim Peters 4c3a0a35cd More on SF bug [#460020] bug or feature: unicode() and subclasses.
tuple(i) repaired to return a true tuple when i is an instance of a
tuple subclass.
Added PyTuple_CheckExact macro.
PySequence_Tuple():  if a tuple-like object isn't exactly a tuple, it's
not safe to return the object as-is -- make a new tuple of it instead.
2001-09-10 23:37:46 +00:00
Tim Peters caaff8d95d test_dir(): Add tests for dir(i) where i is a module subclass. 2001-09-10 23:12:14 +00:00
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.
2001-09-10 21:28:20 +00:00
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.
2001-09-10 20:52:51 +00:00
Guido van Rossum 8bce4acb17 Rename 'getset' to 'property'. 2001-09-06 21:56:42 +00:00
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.).
2001-09-04 01:20:04 +00:00
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 bfa47b0725 Correct name mangling algorithm, and add a comment. 2001-08-31 04:35:14 +00:00
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.)
2001-08-29 15:48:43 +00:00
Guido van Rossum ce129a5e79 Fix the test again due to fewer calls to __getattr__. 2001-08-28 18:23:24 +00:00
Guido van Rossum a5be8eda37 Fix one test to reflect the change in method lookup policy. 2001-08-28 17:58:55 +00:00
Guido van Rossum 9881fc124e supers(): typo -- "if verify" should be "if verbose". 2001-08-24 17:07:20 +00:00
Guido van Rossum c4a1880de4 Add test suite for super(). 2001-08-24 16:55:27 +00:00
Guido van Rossum 76f0cb85c2 Add a test for the new getset type. 2001-08-24 15:24:24 +00:00
Guido van Rossum 65d5d7fac6 Add test for weak references. 2001-08-17 21:27:53 +00:00
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 7e1ff69271 Add early binding of methods to the 2nd metaclass example. 2001-08-17 11:55:58 +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".
2001-08-16 16:56:16 +00:00
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.
2001-08-12 05:24:18 +00:00
Guido van Rossum 9d4fe4298e dynamics(): add tests for dynamic *instances* (which are currently
broken).  Also fix an invalid reference to C (should be S).
2001-08-12 03:38:18 +00:00
Guido van Rossum e45763a8e6 Add test for SF bug #442833 (multiple inheritance). 2001-08-10 21:28:46 +00:00
Guido van Rossum 6d94627f1e Allow AttributeError as well as TypeError for attribute-less objects. 2001-08-10 19:42:38 +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.)
