* transport shortcut b/w client and serverAnand V. Avati2009-05-072-0/+13
| | | | | | 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.

| | | | | | | | Metadata operations now lock only a single byte at offset (LLONG_MAX - 1) instead of the whole file, to avoid contention with writev(). Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* io-threads: Clarify thread count rangeShehjar Tikoo2009-05-052-16/+23
| | | | | | | | | | | | | | | This patch cleans up io-threads behaviour regarding the range values that can be specified for min-threads and max-threads. THe major change is that the min threads have been reduced to 2 to signify that io-threads needs minimum two threads for its operation, while keeping the default number of threads at 16. The idea is to decouple the default thread count from the minimum thread count. Note to Avati: This applies over Raghu's indentation and logging take-3 patch. Signed-off-by: Anand V.

| | | | | | | | | | | | | | 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 Signed-off-by: Anand V.
