* Fix some trivial typos.Erick Tryzelaar2009-06-291-1/+1
| | | | | | | I noticed that there were some minor spelling mistakes/typos in some of the source files. This patch fixes the ones I've found. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* version check between client/server made more specific to protocol only.Amar Tumballi2009-06-292-9/+9
| | | | | | | | | 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>
* server-protocol: interpret the 'op' value properly when a packet is received.Amar Tumballi2009-06-231-4/+3
| | | | | | | | | 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. Avati <avati@dev.gluster.com>
* 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>
* client: Replace saved_fds dict with listShehjar Tikoo2009-06-152-158/+177
| | | | | | | | | | | Thhie change removes a huge inefficiency in file open path where every open resulted in dictionary operations in order to let the client maintain a list of fd_t's being used over a particular client context.

* 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.

* client-protocol: Fix memory corruption in client_lookupRaghavendra G2009-05-161-13/+7
| | | | | | | | - memory corruption was due to new members being added between allocation of buffer for serializing xattr_req dictionary and dict_serialize of xattr_req. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* 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.

* 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.

* client_protocol_reconnect - do not send notify of CHILD_DOWN event if errno ↵Anand V. Avati2009-04-201-1/+1
| | | | | | from transport_connect() was EINPROGRES This bug was racing between a CHILD_UP from poll thread resulting from the event_register() of the new socket called in fuse thread. CHILD_UP would sometimes overtake the CHILD_DOWN for EINPROGRESS. So replicate would receive CHILD_DOWN as the latest event. This resulted in self-heal not happening etc.

| | | | | | | | | | | - 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.
