[AG-TECH] FC7 Issues

Not sure if the FC7 packages are 'complete' and fully supported yet; however I have got AG3 running
on FC7 with a couple of changes.

First off, for some reason doing a 'yum install AccessGrid' failed because of a python-ZSI missing
dependency.  The rpm is in the repository, so I just downloaded/installed it manually:


The second issue was failure to contact the bridge registry.  The logs showed:

06/05/2007 09:41:15 AM -1208486208 RegistryClient     RegistryClient.py:98 ERROR Failed to connect
to registry vv3.mcs.anl.gov:8030
Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/AccessGrid3/AccessGrid/Registry/RegistryClient.py", line
93, in _connectToRegistry
    if self.PingRegistryPeer(tmpServerProxy) > -1:
  File "/usr/lib/python2.5/site-packages/AccessGrid3/AccessGrid/Registry/RegistryClient.py", line

    startTime = serverProxy.Ping(time.time())

  File "/usr/lib/python2.5/xmlrpclib.py", line 1437, in __request
  File "/usr/lib/python2.5/xmlrpclib.py", line 1201, in request
    return self._parse_response(h.getfile(), sock)
  File "/usr/lib/python2.5/xmlrpclib.py", line 1324, in _parse_response
    p, u = self.getparser()
  File "/usr/lib/python2.5/xmlrpclib.py", line 1210, in getparser
    return getparser(use_datetime=self._use_datetime)
AttributeError: TimeoutTransport instance has no attribute '_use_datetime'

I solved this issue by adding a _use_datetime attribute to the Transport class in
/usr/lib/python2.5/xmlrpclib.py (~ line 1160)

    _use_datetime = False

Not sure if these are known issues - but those changes got me rolling.
