* | TST,MAINT: Simplify warning testing in masked arraysSebastian Berg2022-05-271-36/+18
| | | | | | | | | | There is no point in catching the warnigns when raising will do (because we want 0 warnings). That is more informative in any case.
* | TST: Fix uninitialized value in masked ndenumerate testSebastian Berg2022-05-121-1/+1
| | | | | | | | | | | | The test used unintialized values, if NaN happened to be there the test would fail (and generally, uninitialized values being used in tests is bad, since it shows up in valgrind).

| | | | | | | | | | | | | | | | | | | | | | | | By keeping both variants of the keyowrd parameter, we achieve backwards compatibility. The old mispelled variant has been removed from the documentation, the new variant does appear in the documentation and using noth variants raises a TypeError. Additionally, the old variant can only be used as a keyword argument, not as a positional argument. Co-authored-by: Eric Wieser <wieser.eric@gmail.com>

* DEP: Ensure the string promotion FutureWarning is raisedSebastian Berg2021-05-121-1/+1
| | | | | | | | | | | | Promotion errors are currently ignored and instead we use `object` as dtype. This means that the FutureWarning is ignored when raised. It also means that there is no way to opt into "future" behaviour, although arguably, we may want to force `dtype=object` in any case if a promotion error occurred (or some signal at least). Closes gh-18721 Addresses gh-18425 (Does not actually fix it, but chances are we won't)

* BUG: Fix ma coercion list-of-ma-arrays if they do not cast to boolSebastian Berg2021-03-121-0/+19
| | | | | | | | | | | There was a regression here due to force casting to bool, but if that happens to fail (it does, but should not for strings). The mask would just be dropped. Of course masked arrays are held together by faith here, but its a regression. Closes gh-18551
* 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.
