STINNER Victor added the comment: When I wrote the PEP 445, I already proposed to add a new environment variable to install debug hooks on a Python compiled in release mode:
https://www.python.org/dev/peps/pep-0445/#add-a-new-pydebugmalloc-environment-variable But the proposition was rejected because of the PEP 432, but 3 years later, this PEP is still stuck at the draft state. So I propose to move on. Anyway, PYTHONMALLOC is really a corner case since it must be read *very early* (first instruction of main()). Oh by the way, I forgot to explain the initial motivation for this change! It's the issue #26249: "Change PyMem_Malloc to use pymalloc allocator". With this change, applications misuing PyMem_Malloc API (ex: alloc memory with PyMem_Malloc(), free memory with free()) will start to crash. PYTHONMALLOC=debug should help these applications to detect bugs easier and get an obvious error message. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26516> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
