* 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. More specific information is required for debugging, and hence adding the path log. Signed-off-by: Anand V.

* logging related bug fix in server_lookup()Amar Tumballi2009-08-041-4/+3
| | | | | | | | | | | | When 'dict_unserialize' failed, the log message was trying to print 'state->loc.path' and 'state->ino', which gets filled in later stages in flow. Caused segmentation fault when there was a failure. Signed-off-by: Anand V.

* server: don't check for 'loc->parent' in entrylk and inodelk callsAmar Tumballi2009-07-171-4/+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.

* version check between client/server made more specific to protocol only.Amar Tumballi2009-06-291-4/+4
| | | | | | | | | This patch is a step towards giving compatibility between the versions of GlusterFS. Now onwards, the protocol-version won't depend on release versions. In general, multiple glusterfs versions can have common protocol-version. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

| | | | | | | | | 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.

* check if the 'key' is the volume file name itself.Amar Tumballi2009-06-231-14/+34
| | | | | | | | With this patch, one can fetch any volumefile which is not pre-defined in volume file with 'option' in server protocol volume, instead clients can fetch the volume files based on the key name itself [From the confdir only] Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* server-helpers: cleanup connection only if there are no active transports.Raghavendra G2009-06-083-129/+194
| | | | | | | | | | | - thanks to Ioannis Aslanidis <iaslanidis@flumotion.com> for reporting. - breakup the server_connection_cleanup into smaller procedures. - do following operations in a single atomic operation. 1. conn->active_transports-- 2. collecting pointer to lock table and all fds if there are no active transports this will avoid any race conditions.

* 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.

* fd leak fixAnand V. Avati2009-04-222-4/+7
| | | | | | | | | | | | | | 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.

* server-protocol - reimplement connection cleanup to happen in 2 phasesRaghavendra G2009-04-034-22/+206
| | | | | | | | | | | - first phase, which happens when POLLERR is received on transport, releases all locks, flushes all open fds. - second phase, which happens when both the transports of connection destroyed, destroys the containers like lock table, fd table along with the connection. - the first phase, clears up any references to transport held by translators like posix-locks(in the form of blocked locks) paving way for the second phase.
