* Merge p3yk branch with the trunk up to revision 45595. This breaks a fairThomas Wouters2006-04-211-16/+3
| | | | | | | | | | | | | | | | | | | | 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.

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-1/+1
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.

* * Add unittests for iterators that report their lengthRaymond Hettinger2004-04-121-1/+12
| | | | | | * Document the differences between them * Fix corner cases covered by the unittests * Use Py_RETURN_NONE where possible for dictionaries
* Tidied up the implementations of reversed (including the custom onesRaymond Hettinger2004-03-101-16/+20
| | | | | | | | | | | | | | | | | for xrange and list objects). * list.__reversed__ now checks the length of the sequence object before calling PyList_GET_ITEM() because the mutable could have changed length. * all three implementations are now tranparent with respect to length and maintain the invariant len(it) == len(list(it)) even when the underlying sequence mutates. * __builtin__.reversed() now frees the underlying sequence as soon as the iterator is exhausted. * the code paths were rearranged so that the most common paths do not require a jump.
* Eliminate the double reverse option. It's only use caseRaymond Hettinger2004-03-101-13/+1

* Renamed PyObject_GenericGetIter to PyObject_SelfIterRaymond Hettinger2003-03-171-1/+1

* Created PyObject_GenericGetIter().Raymond Hettinger2003-03-171-8/+1
| | | | Factors out the common case of returning self.
* Remove the next() method -- one is supplied automatically byGuido van Rossum2002-07-161-16/+11
| | | | | | | | PyType_Ready() because the tp_iternext slot is set (fortunately, because using the tp_iternext implementation for the the next() implementation is buggy). Also changed the allocation order in enum_next() so that the underlying iterator is only moved ahead when we have successfully allocated the result tuple and index.
* Patch #568124: Add doc string macros.Martin v. Löwis2002-06-131-2/+2

* - New builtin function enumerate(x), from PEP 279. Example:Guido van Rossum2002-04-261-0/+139
enumerate("abc") is an iterator returning (0,"a"), (1,"b"), (2,"c"). The argument can be an arbitrary iterable object.
