* BUG: fix ma.diff not preserving mask when using append/prepend (#22776)Marko Pacak2023-01-193-7/+176

* API: Ensure a full mask is returned for masked_invalidSebastian Berg2022-12-212-1/+18
| | | | | | | | 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 Berg2022-12-192-5/+19
| | | | | | | | | | | | 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 Loukas2022-12-052-1/+9
|/ | | | | | | 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).

| | | | | | | | | | | | | | | | 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)

| * 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.
