* geo-rep: Avoid duplicate stat in xsync changelog processingAravinda VK2014-07-091-6/+24
| | | | | | | | | | | | | | | | | | | | When A file/dir is identified for metadata sync, it was doing duplicate stat to get the metadata to sync. With this patch it avoids doing one additional stat call. Xsync performance will improve. rsync will copy files metadata, so no need to include for processing.

| | | | | | | | | | | | | | | | | | | | | | | | This patch enables geo-replication to be run as an unprivileged user. As of now, this is just the partial support, but is very close to achieve full functionality. Current limitation * Geo-replication executed Gluster CLI commands on the slave via SSH. On a non-root setup, Gluster CLI would run as an unprivileged user, failing to execute the command. As a workaround (for testing), setuid(2) Gluster CLI executable or use the glusterd option to accept commands by unprivileged CLI process. The nature of cli commands are "system::" commands (for key management) and remote volume info fetching. Remote volume info fetching has been modified to use --remote-host gluster cli option rather than ssh and remote cli execution.

* geo-rep: optimizing update stime after directory synchronizationAravinda VK2014-01-221-6/+14
| | | | | | | | | | | | | | | | | | | | | Since xsync crawl generates new changelog when number of entries reaches 8K or when directory is reached. If a directory has number of files less than 8K then respective changelog file will have less entries. Since xsync generated changelog files processed one after the other, so syncjobs are underutilized. hence low bandwidth utilization. With this patch, changelog will be generated for 8K entries only, but stime will be accumulated. Multiple dirs stime will be updated together since the generated changelog will have entries accross the dirs.

* geo-rep: logrotate: Logrotate handlingAravinda VK2013-10-032-15/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In existing georep logrotate was implemented by handling SIGSTOP and SIGCONT, gsyncd was failing to start again after SIGSTOP. New approach uses WatchedFileHandler in logging, which tracks the log file changes or logrotate. Reopens the log file if logrotate is triggered or if same log file is updated from other process. As per python doc: http://docs.python.org/2/library/logging.handlers.html: The WatchedFileHandler class, located in the logging.handlers module, is a FileHandler which watches the file it is logging to. If the file changes, it is closed and reopened using the file name. A file change can happen because of usage of programs such as newsyslog and logrotate which perform log file rotation. This handler, intended for use under Unix/Linux, watches the file to see if it has changed since the last emit. (A file is deemed to have changed if its device or inode have changed.) If the file has changed, the old file stream is closed, and the file opened to get a new stream.
