Raymond Hettinger 37c0fe56b9 Fix minor subclassing issue with collections.Counter 2011-04-15 13:12:21 -07:00
Raymond Hettinger c886a8484d Backport r87672 and r87615, improving tests, using super() instead of direct parent references, and using __reduce__ method for pickling. 2011-01-03 08:59:18 +00:00
Raymond Hettinger 8ebebd8f7e Raymond-Hettingers-MacBook-Pro:py27 raymondhettinger$ cat svn-commit.tmp 
Backport r87594 r87611 and r87612 so that OrderedDict subclassing behavior
better matches dict subclassing (i.e. adding __missing__ works and
extending/overriding the update() methods doesn't break __init__()).
 2011-01-02 01:03:26 +00:00
Amaury Forgeot d'Arc 71431ef51a Backport part of r86217: Fix issues when building without threads 2010-11-09 07:35:26 +00:00

Raymond Hettinger a54b2dac90 Issue #9626: Fix views in collections.OrderedDict(). 2010-08-17 19:03:06 +00:00
Raymond Hettinger fdf1b5642b Minor factoring 2010-04-11 20:39:28 +00:00
Raymond Hettinger 34c35b2788 Add subtract() method to collections.Counter() objects. 2010-04-03 10:22:00 +00:00
Raymond Hettinger dd2fedcd1c Factor-out constant expressions 2010-04-03 07:57:09 +00:00
Raymond Hettinger 6b96ecb0ab Improve clear() method. Keeps key/value refcnts >= 1 until final dict.clear() so that decrefs to zero won't trigger arbitrary code . Also runs a bit faster. 2010-04-03 03:14:28 +00:00
Raymond Hettinger 3928276e64 Clear cyclical references in list based OrderedDict. 2010-04-03 00:39:26 +00:00
Raymond Hettinger e30bc38ce9 Improve code clarity a bit. 2010-03-09 11:29:10 +00:00
Raymond Hettinger aba2293862 Have links in OrderedDicts be native Python lists instead 
of a custom class with __slots__.  This simplifies the
code a bit, reduces memory consumption, improves speed,
and eliminates the need for weak reference proxies.
 2010-03-09 09:58:53 +00:00
Raymond Hettinger 9bd3508530 Add nicer docstrings to namedtuples(). 
Provides better tooltips and looks better in help().

Georg Brandl 7d4b759bd9 Remove unused import. 2010-02-06 22:49:47 +00:00
Raymond Hettinger 5dfc7f9fc8 Issue 6370: Performance issue with collections.Counter(). 2009-06-29 19:10:29 +00:00
Alexandre Vassalotti cb73bdac95 Revert r73401 per Raymond Hettinger's request. 
The rational is the change might cause imcompatiblity problems with
PyYAML. In addition, Raymond wants to kept the different versions of
collections synchronized across Python versions.
 2009-06-12 23:03:35 +00:00

Raymond Hettinger 756ab67a98 Have namedtuple's field renamer assign names that 
are consistent with the corresponding tuple index.
 2009-04-02 22:25:40 +00:00
Raymond Hettinger 2dc90fdfaf Separate initialization from clearing. 2009-03-25 22:41:32 +00:00

Raymond Hettinger 906f95e80b Move initialization of root link to __init__. 2009-03-23 04:42:18 +00:00
Raymond Hettinger f1e2df9780 Add more comments. Improve variable names. 
Make links clearer by using a Link object
instead of a list.  Use proxy links to avoid
circular references.

Raymond Hettinger c8e81ef508 Fix typo 2009-03-19 23:22:25 +00:00
Raymond Hettinger e980d2d44b * Add implementation notes. 
* Re-order methods so that those touching the underlying data
  structure come first and the derived methods come last.
 2009-03-19 23:12:41 +00:00
Raymond Hettinger 2412299be9 * Add clearer comment to initialization code. 
* Add optional argument to popitem() -- modeled
  after Anthon van der Neut's C version.
* Fix method markup in docs.

Raymond Hettinger 2124599eaa Improve implementation with better underlying data structure 
for O(1) deletions.  Big-Oh performance now the same as regular
dictionaries.  Uses a doubly-linked list instead of a list/seq
to track insertion order.
 2009-03-19 15:21:10 +00:00
Raymond Hettinger a61ae6922f Use mixin methods where possible. (2.7 only -- these don't all exist in 3.0) 2009-03-18 22:13:20 +00:00
Raymond Hettinger 131af6505a Backport 70140, 70141, 70143, and 70144. 
Adds tests, switches from list to deque, fixes __reduce__
which was unnecessarily copying __keys.
