* DOC: correct possible list lengths for `extobj` in ufunc callsJosh Wilson2020-03-221-5/+5
| | | | | | | | | | | | | | | | | | | According to the docs, the list can be of lengths 1, 2, or 3, but only length 3 appears to work: ``` >>> import numpy as np >>> np.sin(1, extobj=[16, 1, lambda: None]) 0.8414709848078965 >>> np.sin(1, extobj=[16, 1]) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: UFUNC_PYVALS must be a length 3 list. >>> np.sin(1, extobj=[16]) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: UFUNC_PYVALS must be a length 3 list. ```
* BUG: add missing c_distributions.pxd, enables cython use of random C-API ↵Matti Picus2020-03-161-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (gh-15463) xref gh-14778 As pointed out in the comment by @jamesthomasgriffin, we did not include a pxd file to expose the distribution functions documented in the random c-api. This PR adds a c_distributions.pxd file that exposes them. Squashed commits: * BUG: add missing c_distributions.pxd to enable cython use of random C-API * ENH, TST: add npyrandom library like npymath, test cython use of it * BUG: actually prefix f-string with f * MAINT: fixes from review, add _bit_generato_bit_generator.pxd * STY: fixes from review * BLD: don't use nprandom library for mtrand legacy build * TST: WindowsPath cannot be used in subprocess's list2cmdline * MAINT, API: move _bit_generator to bit_generator * DOC: add release note about moving bit_generator * DOC, MAINT: fixes from review * MAINT: redo dtype determination from review

| * DEP: Deprecate PyUFunc_GenericFunction public C-API functionSebastian Berg2020-01-311-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This function provides mainly the same API as PyObject_Call() with the exception of skipping ufunc overrides and output array wraps. It is fairly unwieldy to use, since ownership of all inputs and outputs is transferred, but otherwise it still uses args and kwargs as inputs. As such, no known usage exists and PyObject_Call seems a reasonable replacement for possible usage. Keeping it around means that we would may have to add tests or risk breaking this function when ufunc code is refactored.
| * DEP: Schedule PyArray_GetArrayParamsFromObject for removalSebastian Berg2020-01-311-63/+6
| | | | | | | | | | | | | | | | | | | | The function has no known usage outside of NumPy. It is fairly complex to use due to how it behaves with scalars, and, at least with a given "flexible" dtype would require additional access to the private PyArray_AdaptFlexibleDType function. Removing the function from public API will simplify refactor work of the dtype and dimension recovery.

* | | MAINT: Const qualify UFunc inner loops (gh-15355)Kai Striega2020-01-211-30/+32
| |/ |/| | | | | | | This PR const qualifies the dimension and strides arguments of PyUFuncGenericFunction. Const qualified arguments make it simpler to reason about the behaviour of these ufuncs and prevents accidental mutation. As the const is now required this PR also const qualifies calls to PyUFuncGenericFunction inside the NumPy source code. This closes #15252

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This slightly modifies the behaviour of `np.choose` (practically a bug fix) and the public function itself. The function is not used within e.g. SciPy, so the small performance hit of this implementation is probably insignificant. The change should help clean up dtypes a bit, since the whole "scalar cast" logic is brittle and should be deprecated/removed, and this is probably one of the few places actually using it. The choose change means that: ``` np.choose([0], (1000, np.array([1], dtype=np.uint8))) ``` will actually return a value of 1000 (the dtype not being uint8).
