Georg Brandl b36e63a5ee The set types can also be called without arguments. 2010-02-28 18:26:37 +00:00
Georg Brandl bca1169e94 #8030: make builtin type docstrings more consistent: use "iterable" instead of "seq(uence)", use "new" to show that set() always returns a new object. 2010-02-28 18:19:17 +00:00
Raymond Hettinger 79628d311f Issue 7263: Fix set.intersection() docstring. 2009-11-18 20:28:22 +00:00
Raymond Hettinger c2b9e1a134 Issue 6573: Fix set.union() for cases where self is in the argument chain. 2009-07-27 20:32:04 +00:00
Antoine Pitrou aa687902f2 Issue #3680: Reference cycles created through a dict, set or deque iterator did not get collected. 2009-01-01 14:11:22 +00:00
Amaury Forgeot d'Arc d78b9dcbc3 #4069: aSet.remove(otherSet) would always report the empty frozenset([]) as the missing key. 
Now it correctly refers to the initial otherset.

Reviewed by Raymond. Will backport to 2.6.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread: 
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

Raymond Hettinger d99bee7c9f Issue 2855: Fix obscure crasher by slowing down the entire module. Mimics what was done to dictionaries in r59223. 2008-05-30 06:49:47 +00:00

Raymond Hettinger a37430a0ce dict.copy() rises from the ashes. Revert r60687. 2008-02-12 19:05:36 +00:00
Raymond Hettinger 17a74c395e Add -3 warnings that set.copy(), dict.copy(), and defaultdict.copy() will go away in Py3.x 2008-02-09 04:37:49 +00:00
Christian Heimes 5b970ad483 Unified naming convention for free lists and their limits. All free lists 
in Object/ are named ``free_list``, the counter ``numfree`` and the upper
limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.

The chances should make it easier to adjust Python for platforms with
less memory, e.g. mobile phones.

Amaury Forgeot d'Arc cab3d98ca1 Ensure that PySet_Add() operates on a newly created frozenset, like PyTuple_SetItem does. 
Add PyFrozenSet_Check(), which was not needed before; The list of Py*Set_Check* macros seems to be complete now.

Add missing NEWS entries about all this.

Raymond Hettinger 7759a0cd76 Factor-out common code with a new macro 2008-01-28 21:47:42 +00:00
Raymond Hettinger ecdcb58950 Make PySet_Add() work with frozensets. 
Works like PyTuple_SetItem() to build-up values in a brand new frozenset.
Also, PyFrozenSet_New() is now guaranteed to produce a distinct new frozenset.

Raymond Hettinger 3dbd4c536d Changes 54857 and 54840 broke code and were reverted in Py2.5 just before 
it was released, but that reversion never made it to the Py2.6 head.
