| | | | | | | | * Use a custom (although slow) PyLong->cint128 conversion if "_PyLong_AsByteArray()" is missing (in PyPy/Limited API). * Avoid large integer conversion for enum types (where shift etc. don't work well).

| * | Fix a signedness compiler warning in vector.to_py (GH-5438)Philipp Wagner2023-05-151-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When compiling cythonized code which uses `std::vector` we get the following compiler warning on GCC 8 and Python 3.9 (which is turned into an error in our case): ``` my_file.cpp: In function ‘PyObject* __pyx_convert_vector_to_py_int(const std::vector<int>&)’: my_file.cpp:4716:33: warning: comparison of integer expressions of different signedness: ‘Py_ssize_t’ {aka ‘long int’} and ‘size_t’ {aka ‘long unsigned int’} [-Wsign-compare] for (__pyx_t_5 = 0; __pyx_t_5 < __pyx_t_4; __pyx_t_5+=1) { ~~~~~~~~~~^~~~~~~~~~~ ``` The generated code in question is as follows: ``` /* "vector.to_py":75 * cdef object item * * for i in range(v.size()): # <<<<<<<<<<<<<< * item = v[i] * Py_INCREF(item) */ __pyx_t_3 = __pyx_v_v.size(); __pyx_t_4 = __pyx_t_3; for (__pyx_t_5 = 0; __pyx_t_5 < __pyx_t_4; __pyx_t_5+=1) { __pyx_v_i = __pyx_t_5; ``` `__pyx_t_5` is of type `‘Py_ssize_t’` (signed), and `__pyx_t_4` aka `__pyx_t_3` is `size_t` (unsigned), causing GCC to rightfully complain. Fix the generated code by explicitly using the signed variant of the vector's size in the loop. This bug has been introduced in https://github.com/cython/cython/pull/4081, which also contains some discussion on the use of signed vs unsigned types. This patch chooses to keep the status quo and only fixes the compiler warning.
