Fix for Client.set_permissions() issue

[JKDingwall]

import pyxs xsc = pyxs.Client(xen_bus_path="/proc/xen/xenbus") xsc.mkdir("/some/path") xsc.set_permissions("/some/path", 'r0')

would raise: Traceback (most recent call last): File "", line 1, in File "/root/.local/lib/python2.7/site-packages/pyxs-0.3-py2.7.egg/pyxs/client.py", line 227, in set_permissions self.ack(Op.SET_PERMS, path, _perms) File "/root/.local/lib/python2.7/site-packages/pyxs-0.3-py2.7.egg/pyxs/client.py", line 154, in ack if self.execute_command(_args) != "OK": File "/root/.local/lib/python2.7/site-packages/pyxs-0.3-py2.7.egg/pyxs/client.py", line 116, in execute_command if not self.COMMAND_VALIDATORS.get(op, lambda _args: True)(_args): File "/root/.local/lib/python2.7/site-packages/pyxs-0.3-py2.7.egg/pyxs/client.py", line 68, in lambda p, *perms: validate_path(p) and validate_perms(perms)), File "/root/.local/lib/python2.7/site-packages/pyxs-0.3-py2.7.egg/pyxs/helpers.py", line 154, in validate_perms raise InvalidPermission(perm) pyxs.exceptions.InvalidPermission: r

With this change:

xsc.set_permissions("/some/path", 'r0', 'w0')

works correctly and verifying the results with xenstore-ls -p shows: some = "" . . . . . . . . . . . . . . . . . . . . . . . . (n0) path = "" . . . . . . . . . . . . . . . . . . . . . . . . (r0,w0)
