* cli: add geo-replication log-rotate commandVenky Shankar2011-11-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Rotating geo-replication master/monitor log files from cli. On invocation, the log file for a given master-slave session is backed up with the current timestamp suffixed to the file name and signal is sent to gsyncd to start logging to a new log file. Sample commands: * Rotate log file for this <master>:<slave> session: gluster volume geo-replication <master> <slave> log-rotate * Rotate log files for all session for master volume <master> gluster volume geo-replication <master> log-rotate * Rotate log files for all sessions: gluster volume geo-replication log-rotate Change-Id: If801743e9f37bd282e68d262203141626ce77e55 BUG: 3519 Reviewed-on: http://review.gluster.com/653 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Csaba Henk <csaba@gluster.com>

* syncdaemon: implement template substitutions for config valuesCsaba Henk2011-04-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | So, for example, a log file setting of /var/log/${mastervol}/${eSlave}.log will be substituted with the volume name of the master and the canonicalized-escaped name of the slave for each master-slave pair. As template expanders, beyond the various forms and derivatives of master and slave, the following are also available: - gsyncd tunables (set in command line or in config) - for regexp sections, regexp group captures can be accessed via "match<i>_<n>", where i=1,2 corresponds to the i-th peer-rx in the section title and n=1,... to the n-th capture. This will enable us to have a static configuration (not having to add new entries on each gsyncd start).

* syncdaemon: give some refactoring to cascading codeCsaba Henk2011-04-041-20/+30
| | | | | | | | | | | | | | | | | | | | | | | - expiry check of foreign volinfo moved back to GLUSTERServer, so that under the hood we can removexattr the expired ones; a nice side-effect is that we can use the same dict layout for foreign and native volinfo (ie., foreign needs no timeout field) - get_volinfo() is renamed to get_sys_volinfo() and most of the logic is stripped off of it (what remained there is the check against foreign master ambiguity) - volinfo transition logic is cut out to an almost purely functional static method (only impurity is the exeption raised upon forbidden volinfo change) - ping renamed to keep-alive, as something called "ping" is not supposed to have payload (yeah, keep-alive is a bit fishy on this front too, but could not come up with better...)

Switch over fcntl lock based pidfile handling which can provide reliable info about status of the process.
