[issue18619] atexit leaks callbacks in subinterpreters
New submission from Antoine Pitrou: atexit uses PEP 3121 module initialization, and by this scheme each subinterpreter gets a separate module state. However, atexit's m_free doesn't actually decref the callbacks: it only frees the callbacks array, thinking the callbacks were already decref'ed when run. This is ok at main interpreter shutdown, but not at subinterpreter shutdown (see issue 18618). -- components: Interpreter Core, Library (Lib) messages: 194098 nosy: Robin.Schreiber, pitrou, sbt priority: normal severity: normal stage: needs patch status: open title: atexit leaks callbacks in subinterpreters type: resource usage versions: Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18619 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
