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

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)

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.

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
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.

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.

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

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.

77ae87c11e Remove file-level typedefs that were inconsistently used throughout the file. 
Just move over to the public API names.

8b2bfbc198 Add -3 option to the interpreter to warn about features that are 
deprecated and will be changed/removed in Python 3.0.

This patch is mostly from Anthony.  I tweaked some format and added
a little doc.
