| * TST: Skip when numba/numpy compat issues cause SystemErrorSebastian Berg2022-12-021-1/+2
| | | | | | | | | | | | | | | | numba is a bit buggy when wrapping ufuncs, so what should be nothing is (on non dev versions) a SystemError and not even an ImportError. So simply catch those too, since it can be a confusing error during dev otherwise.

|\ \ | | | | | | | | | | | | BLD: enable building NumPy with Meson [ci skip]
| * | BLD: enable building NumPy with MesonRalf Gommers2022-11-251-0/+164
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables building with NumPy on Linux and macOS. Windows support should be complete to, but is untested as of now and may need a few tweaks. This contains: - A set of `meson.build` files and related code generation script tweaks, header templates, etc. - One CI job on Linux - Basic docs on using Meson to build NumPy (not yet integrated in the html docs, it's too early for that - this is for early adopters right now). The build should be complete, with the major exception of SIMD support. The full test suite passes. See gh-22546 for the tracking issue with detailed notes on the plan for switching NumPy to Meson as its build system. Co-authored-by: Stefan van der Walt <stefanv@berkeley.edu>

* TST,MAINT: Replace most `setup` with `setup_method` (also teardown)Sebastian Berg2022-10-273-16/+16
| | | | | | | | 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: Fix boundschecking for `random.logseries`Sebastian Berg2022-10-186-19/+46
| | | | | | | | | | | | | | | | Logseries previously did not enforce bounds to be strictly exclusive for the upper bound, where it leads to incorrect behavior. The NOT_NAN check is removed, since it was never used: The current bounded version always excludes NaNs.
* | MAINT: Use Python integers for int to array of uint32 calculationSebastian Berg2022-10-121-4/+4
|/ | | | | | | | | | | The new weak promotion preserves the original type, this makes the `//= 2**32` fail for certain inputs. The alternative would be typing that as `np.int64(2**32)`, but using Python integers seems easier and cleaner. The code was effectively OK before, since the inputs were guaranteed signed (or Python integers) at that point and 2**32 would have been considered like a NumPy `int64`. (Which would be an alternative fix.)

|\ | | | | DOC: Note symmetry requirement in `multivariate_normal` error
| * BUG: Made the error and warning messages for ↵Matteo Raso2022-08-242-4/+4
| | | | | | | | | | | | | | | | | | | | numpy.random.multivariate_normal more descriptive (closes #22140) Issue #22140 says that numpy.random.multivariate_normal incorrectly warns that a non-symmetric positive-semidefinite matrix isn't positive-semidefinite. In the replies, there was some ambiguity over whether it was possible for a positive-semidefinite matrix to be non-symmetric, with reliable sources saying that symmetry is a common condition to add but not actually necessary. To solve this problem, two different members of the Numpy organization decided that the warning and error message "covariance is not positive-semidefinite" should be changed to "covariance is not symmetric positive-semidefinite". However, this change was never actually made yet. Since this change only required me to change a few strings instead of actually changing the code, I've decided to skip the CI jobs. [skip ci]
* | TST: Implemented an unused test for np.random.randintMatteo Raso2022-08-251-17/+16
|/ | | | In numpy/random/tests/test_random.py, a class called TestSingleEltArrayInput had a method called test_randint that was commented out, with the instructions to uncomment it once np.random.randint was able to broadcast arguments. Since np.random.randint has been able to broadcast arguments for a while now, I uncommented the test. The only modification I made to the code was fixing a small error, where the author incorrectly tried to call "assert_equal" as a method of the TestSingleEltArrayInput instead of a function that was imported from numpy.testing. I ran runtests.py, and the new test passed.
