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)

Benjamin Peterson 979395b7a8 Moved testing of builtin types out of test_builtin and into type specific modules 2008-05-03 21:35:18 +00:00

Tim Peters 1f4bcf9edd test_hash(): The test here is different enough from the one in the bug 
report that the stats for expected # of collisions are a little higher.
Updated comments accordingly.

Raymond Hettinger 41bd02256f SF bug #942952: Weakness in tuple hash

Walter Dörwald 1dde95dffa Move list and tuple tests from test_types.py to their own scripts: 
test_tuple.py and test_list.py. Common tests for tuple, list and UserList
are shared (in seq_tests.py and list_tests.py). Port tests to PyUnit.
(From SF patch #736962)
