* MAINT: Pull identical line out of conditional.Ross Barnowski2020-02-221-2/+1
| | | | | | | | There was an identical statement in both possible branches of a conditional. Moved statement out of conditional to eliminate one repititious LOC

* MAINT: Remove implicit inheritance from object class (#15236)Jon Dufresne2020-01-052-7/+7
| | | | | | | Inheriting from object was necessary for Python 2 compatibility to use new-style classes. In Python 3, this is unnecessary as there are no old-style classes. Dropping the object is more idiomatic Python.

| * MAINT: Remove unnecessary 'from __future__ import ...' statementsJon Dufresne2020-01-036-11/+0
| | | | | | | | | | As numpy is Python 3 only, these import statements are now unnecessary and don't alter runtime behavior.

|/ | | | | Dropping the support for python 2, the difference in module setup do not have to be accounted for anymore. This removes the macros and ifdef's related to module setup code and python 2 support.
* DOC: Note FFT type promotion (#14912)Daniel Ching2019-11-151-0/+8
| | | | | | | * DOC: Note FFT type promotion The NumPy FFT implementation will promote `float32` types to `float64` types. This may not be desired for some applications, but the SciPy implementation supports more data types. Closes #14892

* ENH: set correct __module__ for objects in numpy's public APIStephan Hoyer2018-11-131-2/+3
| | | | | | | | | | | | | Fixes GH-12271 Tests verify that everything in ``dir(numpy)`` either has ``__module__`` set to ``'numpy'``, or appears in an explicit whitelist of undocumented functions and exported bulitins. These should eventually be documented or removed. I also identified a handful of functions for which I had accidentally not setup dispatch for with ``__array_function__`` before, because they were listed under "ndarray methods" in ``_add_newdocs.py``. I guess that should be a lesson in trusting code comments :).

|\ | | | | BUG: Return NULL from PyInit_* when exception is raised
| * Return NULL from PyInit_* when exception is raisedMichael Droettboom2018-03-301-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I don't think this is documented anywhere, but I'm pretty sure module init functions should return NULL in order to communicate that an exception occurred during initialization (as is the standard Python/C API convention). It's clear from the CPython code [here](https://github.com/python/cpython/blob/master/Python/importdl.c#L162) that if you don't return NULL, the exception is swallowed and replaced with the message "initialization of %s raised unreported exception". Admittedly, this is only useful for people porting Numpy to new platforms where it is helpful to know where module initialization is failing, but it can't hurt.
* | MAINT: Remove all uses of run_module_suite.Charles Harris2018-04-062-11/+2
| | | | | | | | | | That function is nose specific and has not worked since `__init__` files were added to the tests directories.
* | TST: Update modules `test` to PytestTester.Charles Harris2018-04-041-2/+3
| | | | | | | | | | | | | | | | Numpy can now be tested using the standard `python -c"import numpy; numpy.test()"` construct.
* | MAINT: Remove "bench" from testing modules `__init__`s.Charles Harris2018-03-311-1/+0
| | | | | | | | | | The "bench" testing with the old bench files is no longer supported. These days we use `runtests.py` and `asv`.

| * MAINT: Stop using non-tuple indices internallyEric Wieser2018-02-161-2/+2
| | | | | | | | | | | | By not using this type of indexing, it becomes easier for subclasses to override indexing in a way that works correctly with numpy functions. These locations were found by deprecating the behavior in question, which is deliberately not part of this commit
* | BUG: Improving the accuracy of the FFT implementationNils Becker2018-02-201-46/+81
|/ | | | | | Previously, the numerical constants in the FFT code were not provided at full double precision which led to a loss of accuracy in the FFT operation. Additionally this commit improves the accuracy of the twiddle factor calculation by reducing the argument of exp(2j*pi*m/n) to the first octant before calling the library function. On average the commit lowers the remaining numerical error in the FFT by a factor of ten.

* TST, MAINT: Add `__init__.py` files to tests directories.Charles Harris2017-08-061-0/+0
| | | | | | | | This allows pytest to run with duplicate test file names. Note that `python <path-to-test-file>` no longer works with this change, nor will a simple `pytest numpy`, because numpy is imported from the numpy repository. However, `python runtests.py` and `>>> numpy.test()` are still available.

* MAINT: Rearrange files in numpy/testing module.Charles Harris2017-07-041-1/+1
| | | | | | | | | | | | | | | | | The aim here is to separate out the nose dependent files prior to adding pytest support. This could be done by adding new files to the general numpy/testing directory, but I felt that it was to have the relevant files separated out as it makes it easier to completely remove nose dependencies when needed. Many places were accessing submodules in numpy/testing directly, and in some cases incorrectly. That presented a backwards compatibility problem. The solution adapted here is to have "dummy" files whose contents will depend on whether of not pytest is active. That way the module looks the same as before from the outside. In the case of numpy itself, direct accesses have been fixed. Having proper `__all__` lists in the submodules helped in that.
