Embedded Python creates a large number of memory leaks when trying to load a non-existent module #137005
Description
Bug report
Bug description:
baseName -- This module does not exist; it was renamed for testing to .py.tmp
After Finalize(); completes and the application is closed, a large number of leaks are created. This behavior is not observed if the module exists.
Sample code
PyGILState_STATE state = PyGILState_Ensure();
//
// check script
//
LogMessage(_T("[*] Finding script %s.py...\n"), baseName);
PyObject* pModuleName;
#ifdef _UNICODE
pModuleName = PyUnicode_FromWideChar(baseName, -1);
#else // _UNICODE
pModuleName = PyUnicode_FromString(baseName);
#endif // _UNICODE
if (pModuleName)
{
pModule = PyImport_GetModule(pModuleName);
if (pModule)
{
Py_DECREF(pModule);
pModule = PyImport_ReloadModule(pModuleName);
}
else
{
pModule = PyImport_Import(pModuleName);
}
Py_DECREF(pModuleName);
}
if (!pModule)
{
LogMessage(_T("[-] failed to find module: %s.py\n"), baseName);
PyGILState_Release(state);
return false;
