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

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__()).

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

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.

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.

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.

e980d2d44b * Add implementation notes. 
* Re-order methods so that those touching the underlying data
  structure come first and the derived methods come last.

2412299be9 * Add clearer comment to initialization code.

  after Anthon van der Neut's C version.
* Fix method markup in docs.

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.

131af6505a Backport 70140, 70141, 70143, and 70144. 
Adds tests, switches from list to deque, fixes __reduce__
which was unnecessarily copying __keys.
