Raymond Hettinger 14bd6de0ec SF 560736. Optimize list iteration by filling the tp_iter slot. 2002-05-31 21:40:38 +00:00
Martin v. Löwis 01f94bda38 Patch #552433: Special-case tuples. Avoid sub-type checking for lists. 
Avoid checks for negative indices and duplicate checks for support of
the sequence protocol.

Guido van Rossum 47668928e6 Discard a misleading comment about iter_iternext(). 2001-05-01 17:01:25 +00:00
Guido van Rossum 213c7a6aa5 Mondo changes to the iterator stuff, without changing how Python code 
sees it (test_iter.py is unchanged).

- Added a tp_iternext slot, which calls the iterator's next() method;
  this is much faster for built-in iterators over built-in types
  such as lists and dicts, speeding up pybench's ForLoop with about
  25% compared to Python 2.1.  (Now there's a good argument for
  iterators. ;-)

- Renamed the built-in sequence iterator SeqIter, affecting the C API
  functions for it.  (This frees up the PyIter prefix for generic
  iterator operations.)

- Added PyIter_Check(obj), which checks that obj's type has a
  tp_iternext slot and that the proper feature flag is set.

- Added PyIter_Next(obj) which calls the tp_iternext slot.  It has a
  somewhat complex return condition due to the need for speed: when it
  returns NULL, it may not have set an exception condition, meaning
  the iterator is exhausted; when the exception StopIteration is set
  (or a derived exception class), it means the same thing; any other
  exception means some other error occurred.
