| | * BUG: Fix masked array raveling when `order="A"` or `order="K"`Sebastian Berg2023-04-211-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This transitively fixes gh-22912. I had alooked a bit into whether it is worthwhile to preserve the mask order, but TBH, we seem to not do so in so many places, that I don't think it really is worthwhile. Applying `order="K"` or `order="A"` to the data and mask separately is an big bug though. Closes gh-22912
| * | BUG: Ignore invalid and overflow warnings in masked setitemSebastian Berg2023-04-211-0/+18
| |/ | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Berg2022-12-211-0/+12
| | | | | | | | | | | | | | | | 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 Berg2022-12-191-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | 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 Loukas2022-12-051-0/+2
| | | | | | | | | | | | | | 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).

* | DEP: Deprecate `np.find_common_type`Sebastian Berg2022-11-071-1/+1
|/ | | | | | | | | The function uses the numeric scalar common dtype/promotion rules. These are subtly different from the typical NumPy rules defined by `np.result_type`. Mainly, there is no good reason to have two subtly different rules exposed and `find_common_type` is less reliable, slower, and not really maintainable when it comes to NEP 50.

| | | | | | | | In some cases, the replacement is clearly not what is intended, in those (where setup was called explicitly), I mostly renamed `setup` to `_setup`. The `test_ccompile_opt` is a bit confusing, so left it right now (this will probably fail)

* BUG: Use `keepdims` during normalization in `np.average` and `np.ma.average` ↵Srimukh Sripada2022-06-261-0/+9
| | | | | | | | | (#21851) The keepdims flag needs to be applied during the calculation of the sum of the weights in np.average and np.ma.average. Not passing it causes weights to broadcast incorrectly. Fixes #21850
* API: Define `<`, `<=`, `>`, `>=` for masked arraysSebastian Berg2022-06-211-0/+46
| | | | | | | | | | 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.
