Jeremy Hylton	af68c874a6	Add const to several API functions that take char . 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 *.	21 years ago

Raymond Hettinger	7892b1c651	* Add unittests for iterators that report their length * Document the differences between them * Fix corner cases covered by the unittests * Use Py_RETURN_NONE where possible for dictionaries	22 years ago
Raymond Hettinger	ef9bf4031a	Tidied up the implementations of reversed (including the custom ones 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.	23 years ago
Raymond Hettinger	d2c36261a2	Eliminate the double reverse option. It's only use case was academic and it was potentially confusing to use.	23 years ago

Guido van Rossum	ca5ed5b875	Remove the next() method -- one is supplied automatically by 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.	24 years ago
Martin v. Löwis	14f8b4cfcb	Patch #568124 : Add doc string macros.	24 years ago
Guido van Rossum	7dab2426ca	- New builtin function enumerate(x), from PEP 279. Example: enumerate("abc") is an iterator returning (0,"a"), (1,"b"), (2,"c"). The argument can be an arbitrary iterable object.	24 years ago
