Georg Brandl 12f8107f91 Fix test_descrtut. 2008-06-01 17:05:56 +00:00
Jeffrey Yasskin 960b9b7a2f Move abc._Abstract into object by adding a new flag Py_TPFLAGS_IS_ABSTRACT,
which forbids constructing types that have it set. The effect is to speed

  ./python.exe -m timeit -s 'import abc' -s 'class Foo(object): __metaclass__ = abc.ABCMeta' 'Foo()'

up from 2.5us to 0.201us. This fixes issue 1762.

Eric Smith a9f7d62480 Backport of PEP 3101, Advanced String Formatting, from py3k.
Highlights:
 - Adding PyObject_Format.
 - Adding string.Format class.
 - Adding __format__ for str, unicode, int, long, float, datetime.
 - Adding builtin format.
 - Adding ''.format and u''.format.
 - str/unicode fixups for formatters.

The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk
and py3k.  Any changes from here on should be made to trunk, and
changes will propogate to py3k).

Raymond Hettinger 214b1c3aae SF Bug #215126: Over restricted type checking on eval() function
The builtin eval() function now accepts any mapping for the locals argument.
Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing
down the normal case.  My timings so no measurable impact.

Raymond Hettinger 64958a15d7 Guido grants a Christmas wish:
sorted() becomes a regular function instead of a classmethod.

Raymond Hettinger af28e4b66b Update test to handle list.__reversed__(). 2003-11-08 12:39:53 +00:00
Raymond Hettinger c40b7afee2 Update test to include "sorted" in dir(list). 2003-10-29 07:23:57 +00:00
Guido van Rossum c53f009f94 Introducing __reduce_ex__, which is called with a protocol number argument
if it exists in preference over __reduce__.  Now Tim can go implement this
in cPickle.c.

Tim Peters e2052ab82a One doctest displaying a dict didn't sort it first. *Maybe* this fixes
the AIX problem with this test.

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".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Raymond Hettinger 14bd6de0ec SF 560736. Optimize list iteration by filling the tp_iter slot. 2002-05-31 21:40:38 +00:00
Guido van Rossum 77f6a65eb0 Add the 'bool' type and its values 'False' and 'True', as described in
PEP 285.  Everything described in the PEP is here, and there is even
some documentation.  I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison.  I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.

Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.

Tim Peters 8044055d82 Somebody made list.__dict__ grow a '__doc__' key, but apparently didn't
run the test suite afterwards.  Either that, or whether '__doc__' shows
up is platform-dependent!

Tim Peters a427a2b8d0 Rename "dictionary" (type and constructor) to "dict". 2001-10-29 22:25:45 +00:00
Guido van Rossum 7b9144b2ee Halfway checkin. This is still messy, but it's beginning to address
the problem that slots weren't inherited properly.  override_slots()
no longer exists; in its place comes fixup_slot_dispatchers() which
does more and different work and is table-based.  (Eventually I want
this table also to replace all the little tab_foo tables.)

Also add a wrapper for __delslice__; this required a change in
test_descrtut.py.

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.

Guido van Rossum a4cb78874c Change repr() of a new-style class to say <class 'ClassName'> rather
than <type 'ClassName'>.  Exception: if it's a built-in type or an
extension type, continue to call it <type 'ClassName>.  Call me a
wimp, but I don't want to break more user code than necessary.

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.

Tim Peters a0a6222509 Teach regrtest how to pass on doctest failure msgs. This is done via a
horridly inefficient hack in regrtest's Compare class, but it's about as
clean as can be:  regrtest has to set up the Compare instance before
importing a test module, and by the time the module *is* imported it's too
late to change that decision.  The good news is that the more tests we
convert to unittest and doctest, the less the inefficiency here matters.
Even now there are few tests with large expected-output files (the new
cost here is a Python-level call per .write() when there's an expected-
output file).

Tim Peters 90ba8d9c80 Force "test." into the start of the module name, inherited by class and
type reprs, to accomodate the way Jack runs tests on the Mac.

Guido van Rossum 8bce4acb17 Rename 'getset' to 'property'. 2001-09-06 21:56:42 +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.
