springmeyer added a commit that closed this issue May 18, 2012 springmeyer python: fix leaky My app works fine when I run it from a command prompt in a dos window, but my executable gives the following traceback (I edited the first few lines to simplify, This is one option. Python C Extension i assume David can judge my findings better. ***** dbClass.cxx DCClass:get_class_def #429 return Py_None without a PY_INCREF(Py_None) DCClass::get_owner_class_de #477 return Py_None without a PY_INCREF(Py_None) ***** dcPacker.cxx DCPacker::unpack_object #804 object = Py_None

In other situations different kind of errors could be raised, or the interpreter could crash or segfault. If None were returned in certain functions to indicate failure or something exceptional - and not a regular condition - that would explain that it doesn't fail very often. This is just a guess. http://bugs.python.org/issue6674 Mapnik member springmeyer commented May 18, 2012 And until then pull from the unofficial PPA I maintain at https://launchpad.net/~mapnik/+archive/nightly-2.0/ dpaleino commented May 20, 2012 @springmeyer I was working right now for

Furthermore the values of total_f are calculated in the same loop as count_ef, so total_f[f] >= count_ef[(e, f)], and I don't think it could ever be zero, but even if it https://www.panda3d.org/forums/viewtopic.php?t=1967 Anyway my reasoning was correct, except that it holds for the more general case of forgetting to incref a generic object. –Bakuriu Mar 8 '13 at 10:57 add a comment| up Py_return_none Print some JSON How do I translate "hate speech"?

i looked into the cause of this problem for Panda3D-1.3.2 Panda3D-1.3.2: panda/src/pgraph/pandaNode.cxx: PandaNode::get_python_tag: there is a missing Py_INCREF(Py_None) which is probably causing this problem (at least in my application as far

i did not look further in the Panda3D-1.3.2 source tree, but i looked through Panda3D-CVS to see if there are any more of possible problems. Is there one? Does the local network need to be hacked first for IoT devices to be accesible? Since Py_None is allocated statically in the Objects/object.c file: PyObject _Py_NoneStruct = { _PyObject_EXTRA_INIT 1, &PyNone_Type }; And in Include/object.h there is the define: #define Py_None (&_Py_NoneStruct) So what will happen,
