* BUG: Allow unmodified use of isclose, allclose, etc. with timedeltaSebastian Berg2021-02-041-0/+7
| | | | | | | | | | | | | | Disallowing timedelta64+float promotion (to timedelta64) in all cases (previously it was assymetric and "half allowed") meant that isclose, allclose, np.ma.allclose, and assert_arrays_almost_equal (which uses isclose), would stop work for timedelta64. Hardcoding that timedelta64 is passed on unmodified retains the old behaviour. It may make sense to deprecate or change this behaviour in the future, but for the 1.20 release, the behaviour should be as much unmodified as possible. Closes gh-18286
* MAINT: ma: Remove unused `**options` from MaskedArray `__new__` method.Warren Weckesser2020-11-081-2/+6
| | | | | | | | | | | | | | | | | | | | | | The `__new__` method of `MaskedArray` has the parameter `**options`, but it is not used. This means a mistyped parameter is silently ignored, e.g. if I mistype the `mask` parameter like this, I don't get an error: In [2]: m = np.ma.MaskedArray([1, 2, 3], maks=[0, 1, 0]) In [3]: m Out[3]: masked_array(data=[1, 2, 3], mask=False, fill_value=999999) In this PR, I simply remove `**options` from the signature of `MaskedArray.__new__`. This affected one test. That test was passing the argument `shape=(0, 1, 2)` to the constructor of a subclass of `MaskedArray`, but since any unknown keywords were silently ignored, that use of `shape` had no effect. I replaced it with the positional argument `[[[]], [[]]]`, which I believe has the effect that was originally intended with the use of the `shape` argument.

| | | | | | | 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.

| | | | | | | | | | | | | | | | This prevents consumers from reshaping the mask in place, which breaks things As a result, `x.mask is x.mask` returns `False`, but this was already true of `x.data is x.data`. May also be related to gh-10270
