[issue43145] Leak of locks from multiprocessing.Process
Boris Staletic added the comment:
The `multiprocessing.Process`, on Linux, ends up doing something like this:
pid = os.fork()
if pid == 0: os._exit()
Translated to C:
int main() {
Py_Initialize();
PyOS_BeforeFork();
pid_t pid = fork();
if (pid == 0) {
PyOS_AfterFork_Child(); // Reinitializes stuff.
_exit(0); // Child process exits without cleanup.
}
PyOS_AfterFork_Parent();
Py_Finalize();
}
The call to `_exit()` happens in Lib/multiprocessing/popen_fork.py#L73
My attempts at cleaning this up resulted in even more problems.

[issue43145] Leak of locks in a subprocess
Boris Staletic added the comment:
Slightly simpler C example:
#include
int main()
{
Py_Initialize();
PyObject* multiprocessing = PyImport_ImportModule("multiprocessing");
PyObject* Process = PyObject_GetAttrString(multiprocessing, "Process");
PyObject* p = PyObject_CallNoArgs(Process);
PyObject* start = PyObject_GetAttrString(p, "start");
PyObject* join = PyObject_GetAttrString(p, "join");
Py_DECREF(PyObject_CallNoArgs(start));
Py_DECREF(PyObject_CallNoArgs(join));
Py_DECREF(join);
Py_DECREF(start);
Py_DECREF(p);
Py_DECREF(Process);
Py_DECREF(multiprocessing);

[issue43145] Leak of locks in a subprocess
New submission from Boris Staletic :
The following C code leaks 7 locks allocated with PyThread_allocate_lock:
#include
int main()
{
Py_Initialize();
PyObject* multiprocessing = PyImport_ImportModule("multiprocessing");
PyObject* Process = PyObject_GetAttrString(multiprocessing, "Process");
PyObject* args = PyTuple_New(0);
PyObject* kw = PyDict_New();
PyDict_SetItemString(kw, "target", Process);
PyObject* p = PyObject_Call(Process, args, kw);
PyObject* start = PyObject_GetAttrString(p, "start");
PyObject* join = PyObject_GetAttrString(p, "join");
PyObject_CallNoArgs(start);
PyObject_CallNoArgs(join);
Py_DECREF(join);
Py_DECREF(start);
Py_DECREF(p);
Py_DECREF(kw);
Py_DECREF(args);
Py_DECREF(Process);
Py_DECREF(multiprocessing);
Py_Finalize();
}

[issue42961] Use-after-free (of a heap type) during finalization
Boris Staletic added the comment:
Oops... I uploaded (and pasted) the wrong file. The /correct/ example can be
found here:
https://github.com/pybind/pybind11/pull/2797/#pullrequestreview-570541151
However, I have just realized that the example doesn't really need the embedded
module. The following also shows the use-after-free:
#include
static void pybind11_object_dealloc(PyObject *self) {
auto type = Py_TYPE(self);
type->tp_free(self);
Py_DECREF(type);
}
static PyType_Slot base_slots[] = {{Py_tp_dealloc,
(void*)pybind11_object_dealloc}, {0, nullptr}};
static PyType_Spec base_spec{"B", sizeof(PyObject), 0, Py_TPFLAGS_BASETYPE |
Py_TPFLAGS_HEAPTYPE, base_slots};
int main() {
Py_InitializeEx(1);
auto base_type = PyType_FromSpec(_spec);
auto globals = PyDict_New();
PyDict_SetItemString(globals, "B", base_type);
auto derived_t = PyRun_String("def f():\n"
" class C:\n"
"class D(B):pass\n"
"b=D()\n"
"f()", Py_file_input, globals, nullptr);
Py_DECREF(globals);
Py_DECREF(derived_t);
Py_Finalize();
}

[issue42176] Valgrind reports "Conditional jump or move depends on uninitialised value(s)" in `PyUnicode_AsEncodedString` and `PyUnicode_Decode`
Boris Staletic added the comment: Thanks for looking into this. > Looks like a bug in valgrind. That actually explains why I wasn't able to reproduce this problem on my local machine. Ubuntu 20.04 comes with valgrind 3.15.0, while my local machine has 3.16.1. Upgrading valgrind on Ubuntu 20.04 does fix the issue. This is good enough for me and I guess this can be closed as "not a bug". -- ___ Python tracker <https://bugs.python.org/issue42176> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23972] Asyncio reuseport
New submission from Boris FELD: I'm trying to create some UDP sockets for doing multicast communication. I have the working code in synchronous way and try to port it to asyncio. One last issue is blocking for me, I'm on Mac OS X and for multicast UDP to work, the SO_REUSEPORT must be set on socket before bind. The problem is that I don't have access on socket, it's created inside asyncio method _create_connection_transport. I've seen that SO_REUSEADDR is already set (https://github.com/gvanrossum/tulip-try3/blob/7b2d8abfce1d7ef18ef516f9b1b7032172630375/asyncio/base_events.py#L720), so maybe we could also set SO_REUSEPORT only on platforms where it's available. `if hasattr(socket, 'SO_REUSEPORT')` should works. Or we could add an optional arguments with could be used to set some socket options, it could be more flexible that set SO_REUSEPORT. I could provide a patch for the best solution selected. -- components: asyncio messages: 241213 nosy: Boris.FELD, gvanrossum, haypo, yselivanov priority: normal severity: normal status: open title: Asyncio reuseport type: behavior versions: Python 3.4, Python 3.5, Python 3.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23972 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
