Hi, When Python is built in debug mode, PyObject gets 2 new fields: _ob_prev and _ob_next. These fields change the offset of following fields in the PyObject structure and so breaks the ABI.
I propose to modify the debug build (Py_DEBUG) to no longer imply Py_TRACE_REFS. Antoine Pitrou proposed this idea when the C API was discussed to get a stable ABI. https://bugs.python.org/issue36465 https://github.com/python/cpython/pull/12615 This change makes the debug build ABI closer to the release build ABI, but I am not sure how to compare these two ABI. Technically, C extensions still need to be recompiled. What do you think? -- I also wrote a PR to remove all code related to Py_TRACE_REFS: https://github.com/python/cpython/pull/12614 I don't think that it's right approach. I prefer to keep this special build around to see if anyone needs it, and wait one or two Python releases to decide what to do with it. Victor -- Night gathers, and now my watch begins. It shall not end until my death. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
