Having a tp_clear for all container objects that can be involved in reference cycles will help the GC free memory. BPO-33418 may be contrived but it does demonstrate a problem that could happen in "real" code. If you have a long-running program, tracking down a memory leak due to reference cycles can be fiendishly difficult. That's why Tim originally wrote cyclops and why I started working on cyclic GC in the first place. It is a "quality of implementation" issue. It is not wrong for CPython to leak memory if you create reference cycles (not all types are required to implement the GC protocol). I expect users would be surprised if it happens since the majority have never used Python without the cyclic GC. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38006> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
