New submission from Adam: I think dynload_shlib (and maybe some of the other non-ldl dynamic library loaders?) should close the libraries when the interpreter is shut down. Currently the handles are not ever closed and in ldl's case sometimes leaked.
The reason I desire this behavior is I have Python opening a shared library that I also open (all within the same process), and I want to be able to reload the library at runtime (via dlclose() + dlopen()) by shutting down the Python interpreter, dlclose()/dlopen(), and re-starting Python on the other side, however having the hanging reference to the library within the interpreter is preventing my dlclose() call from unloading the library. I have attached a patch for dynload_shlib.c that tracks all handles returned by dlopen() and will close them properly when the interpreter is shut down. ---------- components: Interpreter Core files: python-dlopen.diff keywords: patch messages: 235490 nosy: Adam priority: normal severity: normal status: open title: dynload_shlib does not close ldl handles when the interpreter is shut down type: behavior versions: Python 2.7 Added file: http://bugs.python.org/file38028/python-dlopen.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23402> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
