* added log message when server fails to send the reply frameAmar Tumballi2009-08-171-4/+8
| | | | | | | | | | | | | As of now, if a frame submit fails on server, there are no logs, and clients will have missing frames (which leads to 'hangs'). Supporting situation like this very tricky without proper log messages. As a step to make our log message lean and meaningful, this log is important. Signed-off-by: Anand V.

* server-lookup: added path info from header to log messageAmar Tumballi2009-08-041-3/+4
| | | | | | | | | | | | in the previous commit, the path info was removed to prevent the segfault, which instead could have been provided from request header directly.

* server: don't check for 'loc->parent' in entrylk and inodelk callsAmar Tumballi2009-07-161-4/+2
| | | | | | | | | | | | the lock operation on entry or inode is going to happen on only one inode, and it doesn't need dentry (with info on parent) for the lock operation to complete. Hence, in server_{inode,entry}lk() calls after server_loc_fill, we -should not- be checking for parent inode. Signed-off-by: Anand V.

| | | | | | | | | Ref: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=35 The check done earlier was not handling the case when a 'op' is == MAX_VALUE (which is not defined), and used to skip to the next array (like gf_mops[MAX] == gf_cbks[0]) Signed-off-by: Anand V.

* transport shortcut b/w client and serverAnand V. Avati2009-05-071-0/+3
| | | | | | 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.

| | | | | | | | | | | | | | 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.
