* syncdaemon: implement template substitutions for config valuesCsaba Henk2011-04-193-22/+66
| | | | | | | | | | | | | | | | | | | | | | | | | 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).

* features/marker-quota: reduce contributions to parents during unlink only if ↵Raghavendra G2011-04-182-4/+33
| | | | | | | | | | | | | | | | | | | it is the last link. - since we are not having different contributions for different (parent, name) pairs, but only for different parents, links present in the same directory will have only one contribution representing all of them. Hence parents will not be updated for each link call and parents account for just file-size instead of (numlinks * filesize). However this patch will cause issues for links present accross directories, as only one of their contributions is subtracted when all of them removed (Here all the links are accounted in their parents, thereby total size accounted is [numlinks * filesize]).

| | | | | | | | | | | | | | - Though we are setting in memory contribution to zero, during updation process contribution is actually fetched from backend. If they are not deleted and if newpath did not exist before doing rename, contributions from oldloc->inode will be retained even for newloc->inode, there by preventing addition of file-size to parents in newpath.
