* SF patch 1546297 (with some tweaks):Guido van Rossum2006-08-251-0/+171
| | | | | Create a real zip iterator object; not using itertools.izip (Brian Holmes).
* Merge p3yk branch with the trunk up to revision 45595. This breaks a fairThomas Wouters2006-04-211-9/+5
| | | | | | | | | | | | | | | | | | | | number of tests, all because of the codecs/_multibytecodecs issue described here (it's not a Py3K issue, just something Py3K discovers): http://mail.python.org/pipermail/python-dev/2006-April/064051.html Hye-Shik Chang promised to look for a fix, so no need to fix it here. The tests that are expected to break are: test_codecencodings_cn test_codecencodings_hk test_codecencodings_jp test_codecencodings_kr test_codecencodings_tw test_codecs test_multibytecodec This merge fixes an actual test failure (test_weakref) in this branch, though, so I believe merging is the right thing to do anyway.
* Use Py_ssize_t for counts and sizes.Martin v. Löwis2006-02-161-1/+1

* SF patch #1020188: Use Py_CLEAR where necessary to avoid crashesRaymond Hettinger2004-09-011-8/+4

* Make iterators length transparent where possible.Raymond Hettinger2004-03-181-1/+14

* Whitespace normalization.Walter Dörwald2003-06-251-3/+3

* 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).
* SF 560736. Optimize list iteration by filling the tp_iter slot.Raymond Hettinger2002-05-311-17/+7

* Patch #552433: Special-case tuples. Avoid sub-type checking for lists.Martin v. Löwis2002-05-081-2/+18
| | | | | Avoid checks for negative indices and duplicate checks for support of the sequence protocol.

* Discard a misleading comment about iter_iternext().Guido van Rossum2001-05-011-1/+0
|
* 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
