Neal Norwitz bf839e2efa Fix the tests by restoring __import__. I think the test is still valid. 2008-01-24 04:14:50 +00:00
Guido van Rossum 9acc387bcf Turn three recently fixed crashers into regular tests. 2008-01-23 23:23:43 +00:00
Brett Cannon a6e515b90d Remove a straggling debugging print line. 2007-12-25 06:44:59 +00:00
Brett Cannon 4e438bcc56 Actually execute the tests for the getter/setter/deleter tests on properties.
Also fix the test by having the test classes inherit from object.

Are the getter/setter/deleter attributes supposed to be able to chain?  As of
right now they can't as the property tries to call what the property returns,
which is another property when they are chained.

Christian Heimes 636afc52c0 I forgot to fix one occurence of new in test_descr 2007-11-27 23:53:14 +00:00
Christian Heimes c756d00cf2 Replaced import of the 'new' module with 'types' module and added a deprecation warning to the 'new' module. 2007-11-27 21:34:01 +00:00
Guido van Rossum d1ef78942a Issue 1416. Add getter, setter, deleter methods to properties that can be
used as decorators to create fully-populated properties.

Brett Cannon 1e534b5425 Fix a crasher where Python code managed to infinitely recurse in C code without
ever going back out to Python code in PyObject_Call().  Required introducing a
static RuntimeError instance so that normalizing an exception there is no
reliance on a recursive call that would put the exception system over the
recursion check itself.

Armin Rigo 9790a27065 Fix for #1303614 and #1174712:
- __dict__ descriptor abuse for subclasses of built-in types
- subclassing from both ModuleType and another built-in types

Thanks zseil for the patch.

Neal Norwitz 0d4c06e06e Whitespace normalization. Ugh, we really need to do this more often.
You might want to review this change as it's my first time.  Be gentle. :-)

Armin Rigo c0ba52d3fd Revert r53997 as per
http://mail.python.org/pipermail/python-dev/2007-March/071796.html .

I've kept a couple of still-valid extra tests in test_descr, but didn't
bother to sort through the new comments and refactorings added in r53997
to see if some of them could be kept.  If so, they could go in a
follow-up check-in.

Neal Norwitz cbd9ee69ee When __slots__ are set to a unicode string, make it work the same as
setting a plain string, ie don't expand to single letter identifiers.

Guido van Rossum ab8802a4f7 Fix warnings about object.__init__() signature.
Two (test_array and test_descr) were bug IMO; the third (copy_reg)
is a work-around which recognizes that object.__init__() doesn't do
anything.

Žiga Seilnacht 6f2d09c949 Patch #1623563: allow __class__ assignment for classes with __slots__.
The old and the new class are still required to have the same slot
names, but the order in which they are specified is not relevant.
2007-03-16 11:59:38 +00:00
Žiga Seilnacht 71436f0229 Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
name. Remove a reference leak that happened if the name could not be
converted to string. Will backport.

Georg Brandl 0fca97a5fb Patch #1674228: when assigning a slice (old-style), check for the
sq_ass_slice instead of the sq_slice slot.
2007-03-05 22:28:08 +00:00
Jeremy Hylton fa955697fa Add checking for a number of metaclass error conditions.
We add some new rules that are required for preserving internal
invariants of types.

1.  If type (or a subclass of type) appears in bases, it must appear
    before any non-type bases.  If a non-type base (like a regular
    new-style class) occurred first, it could trick type into
    allocating the new class an __dict__ which must be impossible.

2. There are several checks that are made of bases when creating a
   type.  Those checks are now repeated when assigning to __bases__.
   We also add the restriction that assignment to __bases__ may not
   change the metaclass of the type.

Add new tests for these cases and for a few other oddball errors that
were no previously tested.  Remove a crasher test that was fixed.

Also some internal refactoring:  Extract the code to find the most
derived metaclass of a type and its bases.  It is now needed in two
places.  Rewrite the TypeError checks in test_descr to use doctest.
The tests now clearly show what exception they expect to see.

Armin Rigo b8d6d73121 Fix the line to what is my guess at the original author's meaning.
(The line has no effect anyway, but is present because it's
customary call the base class __init__).

Michael W. Hudson f390442130 a test for an error condition not covered by existing tests

Martin v. Löwis d5cfa5491a Put method-wrappers into trashcan. Fixes #927248. 2006-07-03 13:47:40 +00:00
Brett Cannon 22565aac3b An object with __call__ as an attribute, when called, will have that attribute checked for __call__ itself, and will continue to look until it finds an object without the attribute. This can lead to an infinite recursion.
Closes bug #532646, again.  Will be backported.

Armin Rigo fd01d7933b (arre, arigo) SF bug #1350060
Give a consistent behavior for comparison and hashing of method objects
(both user- and built-in methods).  Now compares the 'self' recursively.
The hash was already asking for the hash of 'self'.
2006-06-08 10:56:24 +00:00
Tim Peters 171b868195 subclasspropagation(): Squash two more bogus hash(x) == id(x)
tests.  Alas, because only the "x86 OpenBSD trunk" buildbot fails
these tests, and test_descr stops after the first failure, there's
no sane way for me to fix these short of fixing one and then
waiting for the buildbot to reveal the next one.
2006-04-11 01:59:34 +00:00
Tim Peters 85b362f007 specials(): squash another incorrect hash(x) == id(x)
test.  Add some lines that at least invoke the default
__hash__, although there's nothing to check there beyond
that they don't blow up.
2006-04-11 01:21:00 +00:00
Tim Peters 7731dfdaad Huh. This belonged with the last checkin -- no idea why svn
didn't commit it.
2006-04-11 00:44:27 +00:00
Georg Brandl 533ff6fc06 Patch #1434038: property() now uses the getter's docstring if there is
no "doc" argument given. This makes it possible to legitimately use
property() as a decorator to produce a read-only property.
2006-03-08 18:09:27 +00:00
Brett Cannon bf36409e2a PEP 352 implementation. Creates a new base class, BaseException, which has an
added message attribute compared to the previous version of Exception.  It is
also a new-style class, making all exceptions now new-style.  KeyboardInterrupt
and SystemExit inherit from BaseException directly.  String exceptions now
raise DeprecationWarning.

Applies patch 1104669, and closes bugs 1012952 and 518846.

A patch by mwh to check that user-defined mro's are reasonable
enough.
2005-12-29 17:07:39 +00:00
Armin Rigo fd163f92ce SF patch #1390657:
* set sq_repeat and sq_concat to NULL for user-defined new-style
  classes, as a way to fix a number of related problems.  See
  test_descr.notimplemented()).  One of these problems was fixed
  in r25556 and r25557 but many more existed; this is a general
  fix and thus reverts r25556-r25557.

* to avoid having PySequence_Repeat()/PySequence_Concat() failing
  on user-defined classes, they now fall back to nb_add/nb_mul if
  sq_concat/sq_repeat are not defined and the arguments appear to
  be sequences.

* added tests.

Backport candidate.
2005-12-29 15:59:19 +00:00
Armin Rigo c6686b7c7e Added proper reflection on instances of <type 'method-wrapper'>, e.g.
'[].__add__', to match what the other internal descriptor types provide:
'__objclass__' attribute, '__self__' member, and reasonable repr and
comparison.

Added a test.

Guido van Rossum 298e421453 SF patch #685738 by Michael Stone.
This changes the default __new__ to refuse arguments iff tp_init is the
default __init__ implementation -- thus making it a TypeError when you
try to pass arguments to a constructor if the class doesn't override at
least __init__ or __new__.
2003-02-13 16:30:16 +00:00
Guido van Rossum a89d10edc9 Implement another useful feature for proxies: in super(X, x), x may
now be a proxy for an X instance, as long as issubclass(x.__class__, X).

Guido van Rossum 03bc7d3c4d SF #532767: isinstance(x, X) should work when x is a proxy for an X

Did a little cleanup of PyObject_IsInstance() too.
2003-02-12 03:32:58 +00:00
Guido van Rossum b6e5a0c658 Put proper tests in classmethod_get(). Remove the type argument to
descr_check(); it wasn't useful.  Change the type argument of the
various _get() methods to PyObject * because the call signature of
tp_descr_get doesn't guarantee its type.
2003-02-11 18:44:42 +00:00
Guido van Rossum 3f50cdc05e Get rid of the "bozo" __getstate__ that was inserted when __slots__
was used.  This simplifies some logic in copy_reg.py (used by
pickling).  It also broke a test, but this was rewritten to test the
new feature. :-)

Guido van Rossum 373c7412f2 Fix for SF bug #642358: only provide a new with a __dict__ or
__weaklist__ descriptor if we added __dict__ or __weaklist__,
respectively.  With unit test.
2003-01-07 13:41:37 +00:00
Guido van Rossum 613f24fd73 Add a test for a feature added in rev. 2.82 of typeobject.c:
- 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__.

Also test the refinement added in rev. 2.201 that fixes the problem
reported in SF bug #623669.

Also test a similar provision in abstract.c's binary_op1().
2003-01-06 23:00:59 +00:00
Guido van Rossum 2720b0dff8 Add some print statements in verbose mode to announce that the newest

Michael W. Hudson ade8c8b2c3 Nudge getting __module__ and __name__ for new-style classes so that
the results of *setting* __name__ are not so surprising.

If people can suggest more tests, that'd be grand, or is what's there
sufficient?
2002-11-27 16:29:26 +00:00
Michael W. Hudson 7e7c00db0c I don't know why staring at the email to python-checkins made me
see problems with my code that I didn't see before the checkin, but:

When a subtype .mro() fails, we need to reset the type whose __bases__
are being changed, too.  Fix + test.
2002-11-27 15:40:09 +00:00
Michael W. Hudson 586da8fddd Readjustments to the way we cope with exceptions from subclasses'
mro() methods.  Now any exception aborts the whole __bases__ change.

And more tests.

Michael W. Hudson 98bbc49c54 This is my patch:
[ 635933 ] make some type attrs writable

Plus a couple of extra tests beyond what's up there.

It hasn't been as carefully reviewed as it perhaps should, so all readers
are encouraged, nay exhorted, to give this a close reading.

There are still a couple of oddities related to assigning to __name__,
but I intend to solicit python-dev's opinions on these.

Guido van Rossum d32047f038 A tweaked version of Jeremy's patch #642489, to produce better error

2002-10-18 16:33:13 +00:00
Guido van Rossum 6e5680fc83 For some reason (probably cut and paste), __ipow__ for new-style
classes was called with three arguments.  This makes no sense, there's
no way to pass in the "modulo" 3rd argument as for __pow__, and
classic classes don't do this.  [SF bug 620179]

I don't want to backport this to 2.2.2, because it could break
existing code that has developed a work-around.  Code in 2.2.2 that
wants to use __ipow__ and wants to be forward compatible with 2.3
should be written like this:

  def __ipow__(self, exponent, modulo=None):
      ...

Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

immortal object here as a leak.  Made the object mortal again at the end.

Tim Peters 45228ca827 Repaired optimistic comment in new test. 2002-07-11 07:09:42 +00:00
Tim Peters 2484aaea15 Added a test that provokes the hypothesized (in my last checkin comment)
debug-build failure when an instance of a new-style class is resurrected
by a __del__ method -- we simply never had any code that tried this.

This is already fixed in 2.3 CVS.  In 2.2.1, it blows up via

    Fatal Python error: GC object already in linked list

I'll fix it in 2.2.1 CVS next.

Guido van Rossum a96b0df624 Patch from SF bug 570483 (Tim Northover).
In a fresh interpreter, type.mro(tuple) would segfault, because
PyType_Ready() isn't called for tuple yet.  To fix, call
PyType_Ready(type) if type->tp_dict is NULL.
