* | ENH: random: Add the method `permuted` to Generator. (#15121)Warren Weckesser2020-09-022-62/+294
|/ | | | | | | | | | | * ENH: random: Make _shuffle_raw and _shuffle_int standalone functions. * ENH: random: Add the method `permuted` to Generator. The method permuted(x, axis=None, out=None) shuffles an array. Unlike the existing shuffle method, it shuffles the slices along the given axis independently. Closes gh-5173.

* BUG: Ensure SeedSequence 0-padding does not collide with spawn keysRobert Kern2020-06-092-2/+37
| | | | | | | | | | | | | Fixes #16539 The implicit 0-padding that is done to small entropy inputs to make them the size of the internal pool conflicts with the spawn keys, which start with an appended 0. In order to maintain stream compatibility with unspawned `SeedSequence`s, we explicitly 0-pad short inputs out to the pool size only if the spawn key is provided, and thus would trigger the bug. This should minimize the impact on users that were not encountering the bug.

| | | | | | | | | | Fix for #16508. Cython wants every pointer declaration to be on a separate line.
* | BUG: Correct broadcasting when size is not NoneKevin Sheppard2020-06-052-0/+70
|/ | | | | | | Broadcastable size with inputs does not produce an error when size produces a smaller output array than the broadcast input shape. Patch checks that the output shape matches the outer shape of the broadcast fo all inputs and the size when given.
* DEP: Deprecate passing shape=None to mean shape=()Eric Wieser2020-05-312-12/+18
| | | | This requires some minor tweaks in `np.random` because there the two have different meanings, with `()` meaning 0d array and `None` meaning scalar.
* MAINT: precompute log(2.0 * M_PI) in `random_loggam' (gh-16237)Elia Franzella2020-05-191-10/+12

* TST: random: Skip a test if integers are 32 bit.Warren Weckesser2020-04-271-0/+2

* TST: random: Add more repeatability tests for random integers.Warren Weckesser2020-04-272-0/+45
| | | | | | | Add repeatability tests for when the range of the integers is `2**32` (and `2**32 +/- 1` for good measure) with broadcasting. The underlying functions called by Generator.integers and random.randint when the inputs are broadcast are different than when the inputs are scalars.
* MAINT: random: Add assert() statements.Warren Weckesser2020-04-261-0/+11
| | | | | Assert that an invalid value (2**n-1 for n = 8, 16, 32, 64) has not been passed to the Lemire function.
* BUG: random: Generator.integers(2**32) always returned 0.Warren Weckesser2020-04-262-11/+46
| | | | | | | | | | | | When the input to Generator.integers was 2**32, the value 2**32-1 was being passed as the `rng` argument to the 32-bit Lemire method, but that method requires `rng` be strictly less then 2**32-1. The fix was to handle 2**32-1 by calling next_uint32 directly. This also works for the legacy code without changing the stream of random integers from `randint`. Closes gh-16066.
