| | | | Most of this is just emulating the behavior of python's divmod. With a carefully crafted out parameter, we can eliminate a lot of repetition

| * ENH: Create boolean and integer ufuncs for isnan, isinf, and isfinite.Christopher Whelan2019-03-095-3/+88
| | | | | | | | | | | | | | | | Previously, boolean values would be routed through the half implementations of these functions, which added considerable overhead. Creating specialized ufuncs improves performance by ~250x Additionally, enable autovectorization of new isnan, isinf, and isfinite ufuncs.

This seems to be even a little bit faster that doing this by hand and allows the simplicifaction of the algorithm. Note: Profiling and optimization will be done again at a later stage. * MAINT: Reorder arguments of a sum and fix typo Addresses feedback raised in PR. * ENH: Add support for "wrap" mode This completes the first draft of the complete rewrite meaning all unit tests should pass from this commit onwards. * MAINT: Merge functions for "reflect" and "symmetric" mode The set functions were nearly the same, apart from some index offsets. Merging them reduces code duplication. * TST: Add regression test for gh-11216 The rewrite in past commits fixed this bug. * BUG: Fix edge case for _set_wrap_both when pad_amt contains 0. And include test to protect against regression. * MAINT: Simplify and optimize pad modes Major changes & goals: Don't deal with pad area in the front and back separately. This modularity isn't needed and makes handling of the right edge more awkward. All modes now deal with the left and right side at the same time. Move the creation of the linear ramps fully to its own function which behaves like a vectorized version of linspace. Separate calculation and application of the pad area where possible. This means that _get_edges can be reused for _get_linear_ramps. Combine _normalize_shape and _validate_lengths in a single function which should handles common cases faster. Add new mode "empty" which leaves the padded areas undefined. Add documentation where it was missing. * TST: Don't use np.empty in unit tests * MAINT: Reorder workflow in numpy.pad and deal with empty dimensions Only modes "constant" and "empty" can extend dimensions of size 0. Deal with this edge case gracefully for all other modes either fail or return empty array with padded non-zero dimensions. Handle default values closer to their actual usage. And validate keyword arguments that must be numbers. * MAINT: Add small tweaks to control flow and documentation * BUG: Ensure wrap mode works if right_pad is 0 * ENH: Use reduced region of interest for iterative padding When padding multiple dimensions iteratively corner values are unnecessarily overwritten multiple times. This function reduces the working area for the first dimensions so that corners are excluded. * MAINT: Restore original argument order in _slice_at_axis * MAINT: Keep original error message of broadcast_to * MAINT: Restore old behavior for non-number end_values. * BENCH: Make the pad benchmark pagefault in setup * ENH/TST: Preserve memory layout (order) of the input array and add appropriate unit test. * STY: Revert cosmetical changes to reduce diff * MAINT: Pin dtype to float64 for np.pad's benchmarks * MAINT: Remove redundant code path in _view_roi * MAINT/TST: Provide proper error message for unsupported modes and add appropriate unit test. * STY: Keep docstrings consistent and fix typo. * MAINT: Simplify logical workflow in pad * MAINT: Remove dtype argument from _linear_ramp The responsibility of rounding (but without type conversion) is not really need in _linear_ramp and only makes it a little bit harder to reason about. * DOC: Add version tag to new argument "empty" * MAINT: Default to C-order for padded arrays unless the input is F-contiguous. * MAINT: Name slice of original area consistently for all arguments describing the same thing. * STY: Reduce vertical space * MAINT: Remove shape argument from _slice_at_axis Simplifies calls to this function and the function itself. Using `(...,)` instead should keep this unambiguous. This change is not compatible with Python 2.7 which doesn't support this syntax outside sequence slicing. If that is wanted one could use `(Ellipsis,)` instead. * TST: Test if end_values of linear_ramp are exact which was not given in the old implementation `_arange_ndarray`. * DOC: Improve comments and wrap long line * MAINT: Refactor index_pair to width_pair Calling the right value an index is just plain wrong as it can't be used as such. * MAINT: Make _linear_ramp compatible with size=0 * MAINT: Don't rely on negative indices for slicing Calculating the proper positive index of the start of the right pad area makes it possible to omit the extra code paths for a width of 0. This should make the code easier to reason about. * MAINT: Skip calculation of right_stat if identical If the input area for both sides is the same we don't need to calculate it twice. * TST: Adapt tests from gh-12789 to rewrite of pad * TST: Add tests for mode "empty" * TST: Test dtype persistence for all modes * TST: Test exception for unsupported modes * TST: Test repeated wrapping for each side individually. Reaches some only partially covered if-statments in _set_wrap_both. * TST: Test padding of empty dimension with constant * TST: Test if end_values of linear_ramp are exact which was not given in the old implementation `_arange_ndarray`. (Was accidentally overwritten during the last merge). * TST: Test persistence of memory layout Adapted from an older commit 3ac4d2a1b9b258d65f8d2b5f8f25f88e3a0e8f58 which was accidentally overwritten during the last merge. * MAINT: Simplify branching in _set_reflect_both Reduce branching and try to make the calculation of the various indices easier to understand. * TST: Parametrize TestConditionalShortcuts class * TST: Test empty dimension padding for all modes * TST: Keep test parametrization ordered Keep parametrization ordered, otherwise pytest-xdist might believe that different tests were collected during parallelization causing test failures. * DOC: Describe performance improvement of np.pad as well as the new mode "empty" in release notes (see gh-11358). * DOC: Remove outdated / misleading notes These notes are badly worded or actually misleading. For a better explanation on how these functions work have a look at the context and comments just above the lines calling these functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike Python, NumPy integers have fixed sizes. This can lead to confusion when a integer overflow occurs and users expect NumPy integer types to behave similarily to Python integers. This commit explains integer overflow, an example and potential work arounds.

This is inconsistent with most other integer-accepting APIs in numpy, which require these to be actual integers, and raise TypeError when they are not. The new behavior is: * Raise `TypeError` if the argument is a float, but not an integral one * Emit a `DeprecationWarning` if a float like `1.0` is passed, continuing to allow it its old meaning.

This was done using: * A regex find / replace on all but poly and cheb * A manual diff showing that cheb differed only by whitespace * A manual diff showing that poly differed in `deg.ndim == 1` vs `deg.ndim > 0`. Given that this function only allows `deg.ndim <= 1`, and `ndim >= 0`, these two comparison are equivalent.
