* PEP 3123: Provide forward compatibility with Python 3.0, while keepingMartin v. Löwis2007-07-211-4/+2
| | | | | backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and PyVarObject_HEAD_INIT.
* Use Py_VISIT in all tp_traverse methods, instead of traversing manually orThomas Wouters2006-04-151-8/+4
| | | | | | | | using a custom, nearly-identical macro. This probably changes how some of these functions are compiled, which may result in fractionally slower (or faster) execution. Considering the nature of traversal, visiting much of the address space in unpredictable patterns, I'd argue the code readability and maintainability is well worth it ;P

* Renamed PyObject_GenericGetIter to PyObject_SelfIterRaymond Hettinger2003-03-171-2/+2
| | | | | | to more accurately describe what the function does. Suggested by Thomas Wouters.
* Created PyObject_GenericGetIter().Raymond Hettinger2003-03-171-9/+2
| | | | Factors out the common case of returning self.
* Squash a few calls to the hideously expensive PyObject_CallObject(o,a)Guido van Rossum2002-08-161-1/+6
| | | | | | | -- replace then with slightly faster PyObject_Call(o,a,NULL). (The difference is that the latter requires a to be a tuple; the former allows other values and wraps them in a tuple if necessary; it involves two more levels of C function calls to accomplish all that.)
* Moved special case for tuples from iterobject.c toRaymond Hettinger2002-08-091-24/+11
| | | | | | tupleobject.c. Makes the code in iterobject.c cleaner and speeds-up the general case by not checking for tuples everytime. SF Patch #592065.
* Make StopIteration a sink state. This is done by clearing out theGuido van Rossum2002-07-161-62/+47
| | | | | | | | | | object references (it_seq for seqiterobject, it_callable and it_sentinel for calliterobject) when the end of the list is reached. Also remove the next() methods -- one is supplied automatically by PyType_Ready() because the tp_iternext slot is set. That's a good thing, because the implementation given here was buggy (it never raised StopIteration).

* Mondo changes to the iterator stuff, without changing how Python codeGuido van Rossum2001-04-231-21/+63
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* Adding iterobject.[ch], which were accidentally not added. Sorry\!Guido van Rossum2001-04-201-0/+188
