Running test_httpservers on a 64-bit build of Python 2.7 trunk on OS X
10.5:  (I added a print "nobody=", nobody)

test_authorization (__main__.CGIHTTPServerTestCase) ... nobody= 4294967294
Exception happened during processing of request from ('', 55322)

Fixed in r71299 trunk.  Needs backporting to release26-maint and
release30-maint.  (I'm waiting for buildbot results before I do that)
msg85615 - (view) Author: Gregory P. Smith (gregory.p.smith) * (Python committer) Date: 2009-04-06 06:50
merged into release26-maint.  release30-maint still needed.

Closes duplicate Issue3586?
msg87064 - (view) Author: Gregory P. Smith (gregory.p.smith) * (Python committer) Date: 2009-05-03 20:22
release30-maint r72245 (its already been merged into py3k).

Another potential bug discovered in posixmodule.c in the function

posix_lchown(PyObject *self, PyObject *args)
 	int uid, gid;
 	if (!PyArg_ParseTuple(args, "etii:lchown",
 	                      Py_FileSystemDefaultEncoding, &path,
 	                      &uid, &gid))

uid and gid could also cause over flow. Patch attached.

Hope some one can comment on the patch, thanks a lot!

@boya: It's maybe better to open a new issue for posix_lchown.

I think this can be closed, now that there is another issue for posix_lchown.
