| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit attempts to make structure assignment more consistent, and then changes multi-field indices to return a view instead of a copy. Assignment between structures now works "by field position" rather than "by field name". Fixes #2353, fixes #6085, fixes #3351, fixes #6085, fixes #6314, fixes #2346, fixes #7058, fixes #3641, fixes #5994, fixes #7262, fixes #7493

* | 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: Remove `level=` keyword from test arguments.Charles Harris2017-08-051-7/+5
| | | | | | | | | | | | I don't know what that argument was used for, but it showis up in old tests and is not explicitly used within the tests. I assume it was part of an old testing framework and is now longer needed.
* | MAINT/DOC: Use builtin when np.{x} is builtins.{x}.Eric Wieser2017-08-056-48/+48
| | | | | | | | | | | | | | This is the case for x in {int, bool, str, float, complex, object}. Using the np.{x} version is deceptive as it suggests that there is a difference. This change doesn't affect any external behaviour. The `long` type is missing in python 3, so np.long is still useful

|\ \ | | | | | | ENH: Rearrange testing module to isolate nose dependency.
| * | MAINT: Rearrange files in numpy/testing module.Charles Harris2017-07-044-11/+12
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | isinstance(obj, ndarray) will return False if (obj is None) in any case, so no need to check whether (obj is not None) before it. All tests pass on my build (the most recent one at the time making this PR). However, this might have been done for backward compatibility. Will see how the CI tests do.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This may show warnings in downstream projects, which should likely not be there. We could also drop in the normal assert_equal there, which would support NaT, and NaN, but checks for scalarness, which this currently does not (which also could create problems). Works around the only test with this problem, by using the normal assert_equal there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This does not match np.maximum, which is confusing because the masked version has no documentation at all. This uses a similar deprecation approach to gh-8918, noting that the warning is only needed for arrays of more than one dimension. The same remarks apply to `np.ma.minimum`
* | | DEP: Deprecate single-argument np.ma.m(in|ax)imumEric Wieser2017-05-064-13/+27
| | | | | | | | | | | | | | | | | | | | | | | | This shorthand is just inconsistent with `np.maximum`, and just makes the distinction between `np.ma.max` and `np.ma.maximum` even more confusing. Also adds names to these objects, since 1) they're there in core, and 2) they make the warning message more helpful.
