New submission from Tarun Johar <tarun.jo...@gmail.com>:
PEP 384 and PEP 652 define a stable ABI to be used with Python 3.2 and later. On Windows, symbols for the stable ABI are exported from the python3.dll shared library. The following functions are present in Python 3.9 but have been removed from Python 3.10b3: PyObject_AsCharBuffer() PyObject_AsReadBuffer() PyObject_AsWriteBuffer() PyObject_CheckReadBuffer() The justification for the removal of these functions was discussed in this issue: https://bugs.python.org/issue41103 Without these functions, an extension cannot utilize the stable ABI to access the buffer memory of data structures. The buffer protocol is suggested as an alternative, but the buffer functions PyObject_GetBuffer() and PyBuffer_Release() are not present in the stable ABI. While these two functions may be added to the stable ABI, removal of the four functions above makes Python 3.10 incompatible with previous versions. It is requested that the four functions be reinstated and maintained as described in PEP 652. ---------- components: Build messages: 397319 nosy: tarun.johar priority: normal severity: normal status: open title: Buffer support in the stable ABI type: behavior versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44609> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
