* ENH: core: Replace PyArray_CastTo with a call to PyArray_CopyIntoMark Wiebe2011-01-174-84/+163
| | | | | | | | | Since CopyInto uses the dtype transfer mechanism to do the copying, this also fully handles casting. This also exposed a byte order issue in the dtype transfer code of converting to object arrays. The switch from position-based structure copying to name-based copying required a small change to a masked array test as well.
* ENH: core: Add needs_api output boolean from dtype transferMark Wiebe2011-01-177-182/+297
| | | | | This change allows the NEEDS_PYAPI flag to be re-relaxed from the string, unicode, and void types.
* ENH: core: Implement PyArray_CopyInto using the new iteratorMark Wiebe2011-01-167-63/+238
| | | | | | | | This change also uses the dtype conversion code implemented for new iterator buffering, which differs slightly from the previous casting behavior. In particular, fields are matched up by name instead of position, so code depending on that behavior breaks. The loadtxt function has been fixed to not depend on this casting behavior.

* ENH: iter: Add check for buffered output allocation without delayed bufallocMark Wiebe2011-01-123-14/+52
| | | | | | | When allocating an output and specifying it's to be read, most iteration modes allow the code to fill the allocated output with a value before starting actual iteration. When buffering is enabled and delayed buffer allocation is not, this won't work, so throw an error

* ENH: iter: Add mechanism to use critical iteration functions without the GILMark Wiebe2011-01-092-46/+131
| | | | | | | In particular, the Reset*, GetIterNext, and GetGetCoords functions gain a new parameter 'errmsg'. If a non-NULL value is passed into it, error messages are passed back in this parameter instead of setting the Python exception.

* ENH: iter: Add the new iterator to the exposed APIMark Wiebe2011-01-0912-440/+488
| | | | | | | To do this, I also removed the search/replace of 'intp' to 'npy_intp', and did that change manually in a number of files. The NOPREFIX macro-based emulation of C++'s "using namespace" feels a bit off to me anyway.

* ENH: iter: Change nested iteration pattern and add nested_iters Python functionMark Wiebe2011-01-096-154/+715
| | | | | | Nested iteration now uses a function NpyIter_ResetBasePointers, and the NPY_ITER_OFFSETS flag which was the previous way to do this has been removed.
