geo-rep: Avoid duplicate stat in xsync changelog processing

2014-07-09T08:52:24+00:00

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.

geo-rep: Fix the fd leak in worker/agent spawn

2014-06-30T10:40:45+00:00

worker and agent uses pipe to communicate, if worker dies
for some reason agent should get EOF and terminate.

Each worker-agent spawning is done in thread, Due to race
if multiple workers in same node retain the pipe refs of
other workers. Hence agent will not get EOF even if
worker dies.

feature/geo-rep: Fix to retain pause state of gsyncd on restart

2014-06-20T08:17:22+00:00

On soft reboot, geo-rep monitor is writing 'faulty' into status
file. It should not do it if previous state is paused as
glusterd depend on the state file on node restart.

feature/geo-rep: Fix for changelog agent becoming zombie.

2014-06-18T04:47:07+00:00

Monitor process spawns changelog agent and is not
wait on it, hence becoming zombie. When worker is
dies/killed, it respawns both worker and corresponding
agent leaving the earlier changelog agent in zombie
state. This patch addresses this issue by waiting
on agent process in montor process.

geo-rep: Making replica failover check interval configurable

2014-06-12T06:55:31+00:00

by default. Now this option is made configurable and
defaulted to 1 sec.

To change the default value

geo-rep: entry_ops errors handling

2014-06-12T06:52:52+00:00

Xattr.lsetxattr_l call will not raise OSError which
errno_wrap can handle, so we need to use Xattr.lsetxattr
to get proper OSError and errno_wrap ignores or retries
accordingly.

gsyncd / geo-rep: FSH recommended log locations

2014-06-10T16:55:55+00:00

Upgrading "working_dir" on the fly is a bit unclean yet
(though it works) as currently config upgrade does not
support "old" values to be expanded by using configuration
variables.

A new gsyncd options '--pause-on-start' is introduced. When node
reboots, if the status is paused, gsyncd is started with this
option. After gsyncd spawns worker and agent, worker will send 
SIGSTOP to negative pid of monitor to enter pause mode.
