* bpo-42519: Replace PyObject_MALLOC() with PyObject_Malloc() (GH-23587)Victor Stinner2020-12-011-1/+1
| | | | | | | | | No longer use deprecated aliases to functions: * Replace PyObject_MALLOC() with PyObject_Malloc() * Replace PyObject_REALLOC() with PyObject_Realloc() * Replace PyObject_FREE() with PyObject_Free() * Replace PyObject_Del() with PyObject_Free() * Replace PyObject_DEL() with PyObject_Free()
* bpo-42157: Rename unicodedata.ucnhash_CAPI (GH-22994)Victor Stinner2020-10-271-2/+2
| | | | | | | Removed the unicodedata.ucnhash_CAPI attribute which was an internal PyCapsule object. The related private _PyUnicode_Name_CAPI structure was moved to the internal C API. Rename unicodedata.ucnhash_CAPI as unicodedata._ucnhash_CAPI.
* bpo-42157: Convert unicodedata.UCD to heap type (GH-22991)Victor Stinner2020-10-261-76/+44
| | | | | | | Convert the unicodedata extension module to the multiphase initialization API (PEP 489) and convert the unicodedata.UCD static type to a heap type. Co-Authored-By: Mohamed Koubaa <koubaa.m@gmail.com>
* bpo-42157: unicodedata avoids references to UCD_Type (GH-22990)Victor Stinner2020-10-261-105/+111
| | | | | | | | | | * UCD_Check() uses PyModule_Check() * Simplify the internal _PyUnicode_Name_CAPI structure: * Remove size and state members * Remove state and self parameters of getcode() and getname() functions * Remove global_module_state
* bpo-1635741: _PyUnicode_Name_CAPI moves to internal C API (GH-22713)Victor Stinner2020-10-261-13/+15
| | | | | | | | | | The private _PyUnicode_Name_CAPI structure of the PyCapsule API unicodedata.ucnhash_CAPI moves to the internal C API. Moreover, the structure gets a new state member which must be passed to the getcode() and getname() functions. * Move Include/ucnhash.h to Include/internal/pycore_ucnhash.h * unicodedata module is now built with Py_BUILD_CORE_MODULE. * unicodedata: move hashAPI variable into unicodedata_module_state.
* bpo-1635741: Add a global module state to unicodedata (GH-22712)Victor Stinner2020-10-151-54/+107
| | | | | | Prepare unicodedata to add a state per module: start with a global "module" state, pass it to subfunctions which access &UCD_Type. This change also prepares the conversion of the UCD_Type static type to a heap type.

* closes bpo-37966: Fully implement the UAX #15 quick-check algorithm. (GH-15558)Greg Price2019-09-031-24/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of the `unicodedata.is_normalized` function is to answer the question `str == unicodedata.normalized(form, str)` more efficiently than writing just that, by using the "quick check" optimization described in the Unicode standard in UAX #15. However, it turns out the code doesn't implement the full algorithm from the standard, and as a result we often miss the optimization and end up having to compute the whole normalized string after all. Implement the standard's algorithm. This greatly speeds up `unicodedata.is_normalized` in many cases where our partial variant of quick-check had been returning MAYBE and the standard algorithm returns NO. At a quick test on my desktop, the existing code takes about 4.4 ms/MB (so 4.4 ns per byte) when the partial quick-check returns MAYBE and it has to do the slow normalize-and-compare: $ build.base/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \ -- 'unicodedata.is_normalized("NFD", s)' 50 loops, best of 5: 4.39 msec per loop With this patch, it gets the answer instantly (58 ns) on the same 1 MB string: $ build.dev/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \ -- 'unicodedata.is_normalized("NFD", s)' 5000000 loops, best of 5: 58.2 nsec per loop This restores a small optimization that the original version of this code had for the `unicodedata.normalize` use case. With this, that case is actually faster than in master! $ build.base/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \ -- 'unicodedata.normalize("NFD", s)' 500 loops, best of 5: 561 usec per loop $ build.dev/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \ -- 'unicodedata.normalize("NFD", s)' 500 loops, best of 5: 512 usec per loop
