Package: python2.7
Version: 2.7.3~rc1-1
Severity: important
File descriptors opened by PyFile_FromString don't get closed when the
reference count is decreased.
Here's my test program, pythony.c:
#include <Python.h>
int main()
{
int i = 0;
PyObject *obj;
Py_Initialize();
while (i++ < 5) {
obj = PyFile_FromString("hello.py", "r");
assert(obj);
Py_DECREF(obj);
}
Py_Finalize();
}
hello.py is 'print("hello world")'.
I'm compiling it with both Python 2.6 and 2.7.

The Python 2.7 version never calls close, not even at Py_Finalize().
