Kiran Ayyagari resolved DIRSERVER-2014.
---------------------------------------
Resolution: Fixed
> Synchronization is stopped if remote server was not restored during refresh
> interval
> ------------------------------------------------------------------------------------
>
> Key: DIRSERVER-2014
> URL: https://issues.apache.org/jira/browse/DIRSERVER-2014
> Project: Directory ApacheDS
> Issue Type: Bug
> Components: ldap
> Affects Versions: 2.0.0-M16
> Reporter: Alexander Kozlov
> Assignee: Kiran Ayyagari
> Fix For: 2.0.0-M18
>
>
> *Steps to reproduce:*
> 1. Set up synchronization between two servers S1 and S2
> 2. Stop server S2
> 3. Wait more than refresh interval
> 4. Start server S2
> *Observed result:*
> S1 never read/update data from S2
> *Reason:*
> When connection lost and we tried to reconnect at least one time,
> _ReplicationConsumerImpl.disconnected_ field become equals to _true_.
> ReplicationConsumerImpl: {code}
> private ReplicationStatusEnum doRefreshOnly()
> {
> while ( !disconnected )
> {
> CONSUMER_LOG.debug( "==================== Refresh Only
> ==========" );
> try
> {
> doSyncSearch( SynchronizationModeEnum.REFRESH_ONLY, reload );
> CONSUMER_LOG.debug( "--------------------- Sleep for {}
> seconds ------------------", ( config.getRefreshInterval() / 1000 ) );
> Thread.sleep( config.getRefreshInterval() );
> CONSUMER_LOG.debug( "--------------------- syncing again
> ------------------" );
> }
> catch ( InterruptedException ie )
> {
> CONSUMER_LOG.warn( "refresher thread interrupted" );
> return ReplicationStatusEnum.DISCONNECTED;
> }
> catch ( Exception e )
> {
> CONSUMER_LOG.error( "Failed to sync with refresh only mode",
> e );
> return ReplicationStatusEnum.DISCONNECTED;
> }
> }
> return ReplicationStatusEnum.STOPPED;
> }
> {code}
> After _Thread.sleep( config.getRefreshInterval() );_ we exit _while_ loop,
> and method return _ReplicationStatusEnum.STOPPED_ instead of _DISCONNECTED_.
> LdapServer:{code}
> public void startReplicationConsumers() throws Exception
> {
> ...............
> do
> {
> status = consumer.startSync();
> }
> while ( status ==
> ReplicationStatusEnum.REFRESH_REQUIRED );
> if ( status ==
> ReplicationStatusEnum.STOPPED )
> {
> // Exit the loop
> break;
> }
> ...............
> {code}
> In that we exit from thread, and our server never try to get updated data
> from S2..
