New submission from STINNER Victor <vstin...@redhat.com>:
A Python debug build is ABI compatible with a Python release build since Python 3.8 on most platforms (except Windows, Cygwin and Android): https://docs.python.org/3.8/whatsnew/3.8.html#debug-build-uses-the-same-abi-as-release-build It should now be way easier to debug an application with a debug build. I propose to remove runtime debug checks in release mode. assert() is already widely used in the C code base, but there are many runtime checks using PyErr_BadInternalCall() or PyErr_BadArgument. Example: Py_ssize_t PyUnicode_GetLength(PyObject *unicode) { if (!PyUnicode_Check(unicode)) { PyErr_BadArgument(); return -1; } if (PyUnicode_READY(unicode) == -1) return -1; return PyUnicode_GET_LENGTH(unicode); } Attached PR removes these checks when Python is compiled in release mode: when Py_DEBUG is not defined. Even if I marked this issue as "performance", I don't expect a significant speedup. ---------- components: Interpreter Core messages: 346570 nosy: vstinner priority: normal severity: normal status: open title: Disable runtime checks in release mode type: performance versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37406> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
