| | | | | | | | | | | | | | | | | | | | This finishes the deprecation started in gh-9505 removing behaviour that allowed strings/types representing specific dtypes to behave like their more generic supertypes (e.g. the python float would map to floating instead of float64 which it typically maps to).

|/ | | | | | | | | | | (#15736) Currently, in function array_shape_set, ndarray's pointers to dimensions and strides are freed before new array is allocated (Line 71). In case memory error occur, the array is left with dangling pointers. Therefore, we can not recover from such error. * To guarantee array in valid state when memory error occur * Fix: Free cache when nd == 0 to avoid memory leak * Update numpy/core/src/multiarray/getset.c Co-Authored-By: Eric Wieser <wieser.eric@gmail.com>
* MAINT: remove useless `global` statementsEric Wieser2020-03-186-9/+2
| | | | | | | `global` is only needed if a variable appears on the left of an assignment. These variables do not. Most suffer from the misconception that `var[x] = y` requires `var` to be global, but it does not.

| * BUG,MAINT: Remove incorrect special case in string to number castsSebastian Berg2020-03-162-73/+24
| | | | | | | | | | | | | | | | | | The string to number casts fall back to using the scalars and the type setitem function to do the cast. However, before calling setitem, they sometimes already called the Python function for string coercion. This is unnecessary. Closes gh-15608

| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are multiple conditions that `_attempt_nocopy_reshape` checks for when ndarray.shape is mutated directly.

| | | | | | | | | | | | | | | | Removes unnecessary code introduced in #15696. Non-native byte orders were explicitly added to the fast-path check in _var for complex numbers. However, the non-native path is unreachable due to coercion in upstream ufuncs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | var currently has a conditional that results in conjugate being called for the variance calculation of complex inputs.

| * | DEP: Do not allow "abstract" dtype conversion/creationSebastian Berg2020-02-0612-26/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These dtypes do not really make sense as instances. We can (somewhat) reasonably define np.dtype(np.int64) as the default (machine endianess) int64. (Arguably, it is unclear that `np.array(arr_of_>f8, dtype="f")` should return arr_of_<f8, but that would be very noisy!) However, `np.integer` as equivalent to long, is not well defined. Similarly, `dtype=Decimal` may be neat to spell `dtype=object` when you intend to put Decimal objects into the array. But it is misleading, since there is no special meaning to it at this time. The biggest issue with it, is that `arr.astype(np.floating)` looks like it will let float32 or float128 pass, but it will force a float64 output! Arguably downcasting is a bug in this case. A related issue is `np.dtype("S")` and especially "S0". The dtype "S" does make sense for most or all places where `dtype=...` can be passed. However, it is conceptionally different from other dtypes, since it will not end up being attached to the array (unlike "S2" which would be). The dtype "S" really means the type number/DType class of String, and not a specific dtype instance.
