Is this function known to work? It seems like a rewrite of the now-
obsolete fuse.c/fuse_invalidate() and appears to try and flush entries
from the vnode cache, among other effects, but when I call it with a
valid path, like "/", I get a segmentation fault. Here's my code
(using python bindings):
<code>
// python function
def purgeName(path):
return FusePurgeName(path)
// C function
static PyObject *
FusePurgeName(PyObject *self, PyObject *args)
{
char *path;
PyObject *ret;
int err;
PyArg_ParseTuple(args, "s", &path);
printf("%s\n", path);
err = fuse_purge_path_np(path);
// segmentation fault before it returns
printf("%i\n", err);
ret = Py_BuildValue("i", err);
return(ret);
}
</code>
I'm admittedly rusty with C, so I could be passing the path string
incorrectly, but the printf looks correct, and PyArg_ParseTuple is
guaranteed to null-terminate any strings.
If I set path to "" or NULL, the behavior is correct (i.e., it returns
with an errno). Any idea why it faults when I pass it a path string?
