Benjamin Peterson 47fa4d54e8 avoid a function call with redundant checks for dict size 2012-10-31 14:22:12 -04:00
Benjamin Peterson 0ec820fc5f only fast-path fromkeys() when the constructor returns a empty dict (closes #16345) 2012-10-31 14:05:55 -04:00
Antoine Pitrou 6a1cd1b3b1 Issue #13521: dict.setdefault() now does only one lookup for the given key, making it "atomic" for many purposes. 
Patch by Filip Gruszczyński.

Antoine Pitrou 1fba62427c The tracking statistics were actually too pessimistic 2009-03-23 19:17:00 +00:00
Antoine Pitrou f8387af262 Issue #4688: Add a heuristic so that tuples and dicts containing only 
untrackable objects are not tracked by the garbage collector. This can
reduce the size of collections and therefore the garbage collection overhead
on long-running programs, depending on their particular use of datatypes.

(trivia: this makes the "binary_trees" benchmark from the Computer Language
Shootout 40% faster)

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
Andrew M. Kuchling a4127173f8 Punctuation fix; expand dict.update docstring to be clearer 2008-10-04 21:51:59 +00:00
Georg Brandl 1e13ea94a3 - Issue #3537: Fix an assertion failure when an empty but presized dict 
object was stored in the freelist.

Nick Coghlan 53663a695e Issue 2235: __hash__ is once again inherited by default, but inheritance can be blocked explicitly so that collections.Hashable remains meaningful 2008-07-15 14:27:37 +00:00
Raymond Hettinger a27474c345 Issue 3230: Do not the set specific size macro. 2008-06-28 22:16:53 +00:00
Robert Schuppenies 161b92103c Corrected inconsistencies in sizeof tests and addressed issue pointed 
out by Jean Brouwers.

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.
 2008-06-09 04:58:54 +00:00
Georg Brandl 7a6de8b0f4 Some style nits. Also clarify in the docstrings what __sizeof__ does. 2008-06-01 16:42:16 +00:00
Robert Schuppenies 51df064767 Issue #2898: Added sys.getsizeof() to retrieve size of objects in bytes. 2008-06-01 16:16:17 +00:00
Christian Heimes 593daf545b Renamed PyString to PyBytes 2008-05-26 12:51:38 +00:00
Benjamin Peterson f19a7b90bd A little reformating of Py3k warnings 2008-04-27 18:40:21 +00:00
Benjamin Peterson 9f4f48114f Use PyErr_WarnPy3k throughout 2008-04-27 03:01:45 +00:00
Georg Brandl d65ab950c1 Fix tabs. 2008-03-25 08:31:32 +00:00
Georg Brandl d5b635f196 Make Py3k warnings consistent w.r.t. punctuation; also respect the 
EOL 80 limit and supply more alternatives in warning messages.
 2008-03-25 08:29:14 +00:00
Steven Bethard ae42f33cdf Add py3k warnings for object, type, cell and dict comparisons. This should resolve issue2342 and partly resolve issue2373. 2008-03-18 17:26:10 +00:00
Christian Heimes 09bde04154 Use PY_FORMAT_SIZE_T instead of z for string formatting. Thanks Neal. 2008-02-24 12:26:16 +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 48397d6c22 Use prefix decrement 2008-02-08 00:14:34 +00:00
Christian Heimes f75dbef208 Deallocate content of the dict free list on interpreter shutdown 2008-02-08 00:11:31 +00:00
Christian Heimes b4ee4a16f4 Added some statistics code to dict and list object code. I wanted to test how a larger freelist affects the reusage of freed objects. Contrary to my gut feelings 80 objects is more than fine for small apps. I haven't profiled a large app yet. 2008-02-07 17:15:30 +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.

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.
 2008-01-25 19:24:46 +00:00
Christian Heimes e93237dfcc #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and Py_REFCNT. Macros for b/w compatibility are available. 2007-12-19 02:37:44 +00:00
Raymond Hettinger fd7ed407d7 Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary. 
Allows dictionaries to be pre-sized (upto 255 elements) saving time lost
to re-sizes with their attendant mallocs and re-insertions.

Has zero effect on small dictionaries (5 elements or fewer), a slight
benefit for dicts upto 22 elements (because they had to resize once
anyway), and more benefit for dicts upto 255 elements (saving multiple
resizes during the build-up and reducing the number of collisions on
the first insertions).  Beyond 255 elements, there is no addional benefit.

Guido van Rossum 31645ba4a0 Fix bug #1517, a segfault in lookdict(). 2007-11-29 18:25:12 +00:00
Guido van Rossum 64c06e327d Backport of _abccoll.py by Benjamin Arangueren, issue 1383. 
With some changes of my own thrown in (e.g. backport of r58107).

Raymond Hettinger 34448790db Optimize common case for dict.fromkeys(). 2007-11-09 23:14:44 +00:00
Raymond Hettinger cdcf887999 Optimize dict.fromkeys() with dict inputs. Useful for resetting bag/muliset counts for example. 2007-11-07 02:26:17 +00:00
