| * BUG: Correct shuffling of objects in 1-d array likesSebastian Berg2021-02-223-3/+39
| | | | | | | | | | | | | | | | | | While introducing the buffer fixed the in-place problem years ago, running valgrind (and masked arrays) pointed out to me that without the additional `...` NumPy will unpack and repack objects leading to slightly incorrect results. MAINT: Warn about shuffle bug instead of fixing it in old random API

| | | | | | | | | | | | | | | | | | | | | | | | Use 'from None' when the ValueError is raised when the first argument to `choice` is not an array and not an integer. Also fix the error message for the ValueError, and add a missing space to two other error messages.

| | | | | | | | | | | | | | | | | | This rewrite better reflects the cited reference R example by offering a 2-tailed test and more accurate language. Closes #18370.
* | | TST: Add test for shuffle warning and assert stacklevelSebastian Berg2021-02-191-0/+12
| | | | | | | | | | | | | | | | | | | | | The test checks that the warning originates in the correct file (test_random.py). I am not quite sure how safe the test is, though. Unfortunately, there is no "obvious" way to test stacklevels.
* | | BUG: fix stacklevel in warning within random.shuffleSebastian Berg2021-02-192-10/+12
| | | | | | | | | | | | | | | Cython does _not_ add a new stacklevel (at least at this time), so `stacklevel=1` (or ommiting it) is, maybe surprisingly, correct.
