* glusterd, cli: handle uuid conflicts in probe gracefullyRaghavendra Bhat2012-07-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | A commonly faced problem among glusterfs users is: after a fresh installation of glusterfs in a virtual machine, the VM image is cloned to make multiple instances of the server. This breaks glusterd because right after glusterfs installation on the first boot glusterd would have created the node UUID and this gets inherited into the clone. The result is wierd behavior at the time of peer probe where glusterd does not (yet) deal with UUID collisions in a user friendly way. With this patch the peer which got the probe request will compare the uuid of the machine which send the probe request with its own uuid and send the proper error to cli if the uuids are same.

* rpc: Fixed ping timer algo.Krishnan Parthasarathi2012-06-301-1/+0
| | | | | | | | | | | | | | | | | | | | | The purpose of the ping timer is to assert the absence of any evidence the server is possibly alive. The current implementation updates the 'last_sent' timer in the following points in time, - rpc_clnt_submit: when rpc messages are being queued at the transport layer. (wrong!, since we have no way to determine if server actually received the message) - rpc_clnt_notify: when client receives pollout event on sending a message on the 'wire'. (correct, since it indicates ACK from server) The fix removes the 'incorrect' update of 'last_sent'.

* localtime and ctime are not MT-SAFEKaleb S. KEITHLEY2012-06-291-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of nit-level issues throughout the source with the use of localtime and ctime. While they apparently aren't causing too many problems, apart from the one in bz 828058, they ought to be fixed. Among the "real" problems that are fixed in this patch: 1) general localtime and ctime not MT-SAFE. There's a non-zero chance that another thread calling localtime (or ctime) will over-write the static data about to be used in another thread 2) localtime(& <64-bit-type>) or ctime(& <64-bit-type>) generally not a problem on 64-bit or little-endian 32-bit. But even though we probably have zero users on big-ending 32-bit platforms, it's still incorrect. 3) multiple nested calls passed as params. Last one wins, i.e. over- writes result of prior calls. 4) Inconsistent error handling. Most of these calls are for logging, tracing, or dumping. I submit that if an error somehow occurs in the call to localtime or ctime, the log/trace/dump still should still occur. 5) Appliances should all have their clocks set to UTC, and all log entries, traces, and dumps should use GMT. 6) fix strtok(), change to strtok_r() Other things this patch fixes/changes (that aren't bugs per se): 1) Change "%Y-%m-%d %H:%M:%S" and similar to their equivalent shorthand, e.g. "%F %T" 2) change sizeof(timestr) to sizeof timestr. sizeof is an operator, not a function. You don't use i +(32), why use sizeof(<var>). (And yes, you do use parens with sizeof(<type>).) 3) change 'char timestr[256]' to 'char timestr[32]' where appropriate. Per-thread stack is limited. Time strings are never longer than ~20 characters, so why waste 220+ bytes on the stack? Things this patch doesn't fix: 1) hodgepodge of %Y-%m-%d %H:%M:%S versus %Y/%m/%d-%H%M%S and other variations. It's not clear to me whether this ever matters, not to mention 3rd party log filtering tools may already rely on a particular format. Still it would be nice to have a single manifest constant and have every call to localtime/strftime consistently use the same format.

* protocol/server: add and remove the transports from the list, inside the lockRaghavendra Bhat2012-03-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Till now for graph changes, glusterfs client used to remember the old graph also. Hence the transport object on the server corresponding the old graph never received disconnect. But now since the graph cleanup is happening, transport on the server side gets disconnect for the cleaned up graph. Server maintains, all the transports in a list. But addition of the new transport to the list, or removal of the transport from the list is not happening within the lock. Thus if a thread is accessing a transport (in cases of statedump, where each transprt's information is dumped), and the server gets a disconnect on that transport, then it leads to segfault of the process. To avoid it do the list (of transports) manipulation inside the lock.

* protocol/client,server: fcntl lock self healing.Mohammed Junaid2012-02-202-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently(with out this patch), on a disconnect the server cleans up the transport which inturn closes the fd's and releases the locks acquired on those fd's by that client. On a reconnect, client just reopens the fd's but doesn't reacquire the locks. The application that had previously acquired the locks still is under the assumption that it is the owner of those locks which might have been granted to other clients(if they request) by the server leading to data corruption. This patch allows the client to reacquire the fcntl locks (held on the fd's) during client-server handshake. * The server identifies the client via process-uuid-xl (which is a combination of uuid and client-protocol name, it is assumed to be unique) and lk-version number. * The client maintains a list of process-uuid-xl, lk-version pair for each accepted connection. On a connect, the server traverses the list for a matching pair, if a matching pair is not found the the server returns lk-version with value 0, else it returns the lk-version it has in store. * On a disconnect, the server and client enter grace period, and on the completion of the grace period, the client bumps up its lk-version number (which means, it will reacquire the locks the next time) and the server will distroy the connection. If reconnection happens within the grace period, the server will find the matching (process-uuid-xl, lk-version) pair in its list which guarantees that the fd's and there corresponding locks are still valid for this client. Configurable options: To set grace-timeout, the following options are option server.grace-timeout value option client.grace-timeout value To enable or disable the lk-heal, option lk-heal [on|off] gluster volume set command can be used to configurable options Change-Id: Id677ef1087b300d649f278b8b2aa0d94eae85ed2 BUG: 795386 Signed-off-by: Mohammed Junaid <junaid@redhat.com> Reviewed-on: http://review.gluster.com/2766 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>

Other commands use either one of the 2 generic output routines, cli_xml_output_str() & cli_xml_output_dict(). NOTE: When using "all" for "volume status" and "volume info" the XML output will have multiple roots.
