* | ENH: Implement string comparison ufuncs (or almost) (#21041)Sebastian Berg2022-06-101-0/+45
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * ENH: Implement string comparison ufuncs (or almost) This makes all comparison operators and ufuncs work on strings using the ufunc machinery. It requires a half-manual "ufunc" to keep supporting void comparisons and especially `np.compare_chararrays` (that one may have a bit more overhead now). In general the new code should be much faster, and has a lot of easier optimization potential. It is also much simpler since it can outsource some complexities to the ufunc/iterator machinery. This further fixes a couple of bugs with byte-swapped strings. The backward compatibility related change is that using the normal ufunc machinery means that string comparisons between string and unicode now give a `FutureWarning` (instead of just False). * MAINT: Do not use C99 tagged struct init in C++ C++ does not like it (at least not before C++20)... GCC and clang don't seem to mind, but MSVC seems to. * BENCH: Add basic string comparison benchmarks * DOC,STY: Fixup string-comparisons comments based on review Thanks to Marten's comments, a few clarfications and slight fixups. * ENH: Use `memcmp` because it may be faster for the byte case * TST: Improve string and unicode comparison tests. * MAINT: Use switch statement based on review As suggested be Serge. Co-authored-by: Serge Guelton <serge.guelton@telecom-bretagne.eu> * TST: Make unicode byte-swap test slightly more concrete The issue is that the `view` needs to use native byte-order, so just ensure native byte-order for the view, and then do another cast to get it right. * BUG: Add `np.compare_chararrays` to test and fix typo * TST: Add test for empty string comparisons * TST: Fixup string test based on martens review * MAINT: Move definitions back into string_ufuncs.h * MAINT: Use enum class for comparison operator templating This removes the need for a dynamic (or static) assert in the switch statement. * Template version of add_loop to avoid redundant code * STY: Fixup style, two spaces, error is -1 * STY: Small `string_ufuncs.cpp` fixups based on Serge's review * MAINT: Fix merge conflict (ensure_dtype_nbo was removed) Co-authored-by: Serge Guelton <serge.guelton@telecom-bretagne.eu>

| * MAINT,ENH: Rewrite scalar math logicSebastian Berg2022-04-241-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit tries to redo the scalar math logic to take some more care about subclasses, but most of all introduce logic to defer to the `other` if `self` can be cast to it safely (i.e. it is the correct promotion). This makes things much faster and more reliable, since we now use defer much less to `ufuncs` indirectly. This ensures that integer overflows are reported more reliably. Another major point about it, is that this reorganizes the coercion of Python int, float, complex (and bool). This should help a bit with switching to "weak" Python scalars. This may just be a first step on a longer path...
* | DEV: Pin setuptools in the asv configSebastian Berg2022-05-062-0/+2
|/ | | | | | | | | | | Adding the setuptools version to the matrix makes sure that asv (run through `runtests`) locally works again. I am not quite sure what changed that I now run into this issue and previously do not (and neither does the CI runner yet). There may be a better solution, but this seems fine for now? Closes gh-21428
