transport shortcut b/w client and server

2009-05-06T19:54:41+00:00

This patch makes the server pass back the transport pointer of the client. If the UUID matches, the client makes the local transport 'shortcut' with the remote transport (pointer received from server)

The shortcut simulates a socket queue. Instead of serialized messages going over the network and getting queued in the tcp socket queue, the messages get queued in a transport specific queue picked by a polling thread.

fd leak fix

2009-04-22T07:37:22+00:00

steps:
  - server_finodelk uses req->volume pointer into state->volume
  - finodelk is queued by locks translator
  - c call returns from server_pollin and hdr is FREE'd
  - now state->volname is pointing to FREE'ed region (junk)
  - server_finodelk_cbk calls gf_add_locker
  - gf_add_locker remembers lock with junked path along with fd_ref
  - gf_del_locker from new server_finodelk cannot string match with junked volume thus
    lock is not deleted, hence fd_ref remains as a leak
