* BUG: Fix masked array ravel order for A (and somewhat K)Sebastian Berg2023-04-281-1/+1
| | | | | | Swaps the order to the correct thing and thus closes gh-23651
* BUG: Ignore invalid and overflow warnings in masked setitemSebastian Berg2023-04-211-0/+12
| | | | | | | | | | | | Giving a warning for invalid/overflow in settitem/casts is right (IMO), however for masked arrays it can be surprising since the warning is not useful if the value is invalid but also masked. So, simply blanket ignore the relevant warnings in setitem via errstate. (There may be some other cases like `.astype()` where it might be helpful to MA users to just blanket opt-out of these new warnings.) Closes gh-23000

| * BUG: ma with structured dtypeTyler Reddy2023-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes #22041 * add regression test and fix for creating a masked array with a structured dtype; the test is simply for lack of error in the repoducer * the concern expressed by core team in matching issue was that `astropy` might be negatively affected; I ran full `astropy` (hash: `c9ad7c56`) test suite locally with this feature branch and it seemed "ok," just 1 unrelated network failure in the network-requiring tests (`test_ftp_tls_auto`): ```1 failed, 21430 passed, 3490 skipped, 176 xfailed, 23275 warnings in 430.18s (0:07:10)```

* BUG: masked array proper deepcopiesTyler Reddy2023-02-231-1/+14
| | | | | | | | | | | | | | | | | Fixes #22556 Fixes #21022 * add regression test and fix for gh-22556, where we were relying on the array `copy` arg to deepcopy a compound object type; I thought about performance issues here, but if you are already in the land of `object` and you are explicitly opting in to `deepcopy`, it seems like performance might be wishful thinking anyway * add regression test and fix for gh-21022--this one was weirder but seems possible to sidestep by not trying to assign a shape of `()` to something that already has shape `()` and a non-writeable `shape` attribute

* API: Ensure a full mask is returned for masked_invalidSebastian Berg2022-12-211-1/+6
| | | | | | | | Matplotlib relies on this, so we don't seem to have much of a choice. I am surprised that we were not notified of the issue before release time. Closes gh-22720, gh-22720
* BUG: Do not use getdata() in np.ma.masked_invalidSebastian Berg2022-12-191-5/+5
| | | | | | | | | | | | This is the minimal solution to fix gh-22826 with as little change as possible. We should fix `getdata()` but I don't want to do that in a bug-fix release really. IMO the alternative is to revert gh-22046 which would also revert the behavior noticed in gh-22720 (which seems less harmful though). Closes gh-22826
* ENH: Speedup masked array creation when mask=None (#22725)Lefteris Loukas2022-12-051-1/+7
| | | | | | | This PR Closes gh-17046. The problem was that when calling mask=None, the array creation took seconds compared to the microseconds needed when calling mask=False. Using `mask=None` is a bit dubious, since it has a different meaning from the default `mask=nomask`, but the speed trap is so hard to find, that it seems pragmatic to support it. OTOH, it also would seem fine to deprecate the whole path (or maybe see if the path can be sped up so that the speed difference isn't forbidding eough to bother).

| * MAINT: Structured MA fill value workaround by adding array castSebastian Berg2022-10-051-1/+7
| | | | | | | | | | | | | | | | | | | | This wraps the fill value into an array, the default fill value for all ointegers is 99999 which doesn't work for many integer dtypes. Note that this might still subtle change the behavior in other code paths where we cannot avoid this. Plus, the deprecationwarning may show up (and in fact be a "in the future will use the default fill value" warning).

* BUG: fix ma.minimum.reduce with axis keywordRuth Comer2022-07-161-0/+2
| | | | | | | | | | | Fixes the problem reported at https://github.com/numpy/numpy/pull/21977#issuecomment-1186082534 The reduce method here effectively calls itself with an unmasked MaskedArray (mask=nomask) and then expects either a MaskedArray or a scalar. This change ensures that an ordinary ndarray is converted to a MaskedArray, following the pattern already used in mean and var in this module.

* API: Define `<`, `<=`, `>`, `>=` for masked arraysSebastian Berg2022-06-211-1/+19
| | | | | | | | | | This defines the comparison operators (other than `==` and `!=`) explicitly for masked arrays. The mask is ignored for the resuling `res._data` (unlike `==` and `!=` which take the mask into account. Closes gh-21770, although the way that masked arrays propagate the fill-value seems generally broken and error prone.
