-----------------------------------

             Summary: These changes of the PID(org.apache.karaf.cellar.groups)  
which in both blacklist inbound and blacklist outbound can be synchronized to 
other karaf instance
                 Key: KARAF-1408
                 URL: https://issues.apache.org/jira/browse/KARAF-1408
             Project: Karaf
          Issue Type: Bug
          Components: cellar-config
            Reporter: Meifang Shen


About the configuration of the PID(org.apache.karaf.cellar.groups) as follows:
{noformat} 
default.config.whitelist.inbound=*
default.config.whitelist.outbound=*
default.config.blacklist.inbound=org.apache.karaf.cellar.groups,org.apache.karaf.cellar.instance,org.apache.karaf.cellar.node,org.apache.karaf.management
default.config.blacklist.outbound=org.apache.karaf.cellar.groups,org.apache.karaf.cellar.instance,org.apache.karaf.cellar.node,org.apache.karaf.management
default.config.sync=true

default.features.whitelist.inbound=*
default.features.whitelist.outbound=*
default.features.blacklist.inbound=cellar,jetty,http
default.features.blacklist.outbound =cellar,jetty,http
default.features.sync=true
default.features.repositories.sync=true

default.bundle.whitelist.inbound=none
default.bundle.whitelist.outbound=none
default.bundle.sync=false

default.obr.urls.sync=true
default.obr.bundles.sync=true
{noformat} 

Please note: the pid "org.apache.karaf.cellar.groups" is in blacklist.

Locally there are three karaf instances(node1, node2, node3), all are installed 
the feature cellar.

(1)would like to test this property "default.features.blacklist.inbound".

Expect that blacklist inbound works as below:
=> one node1 has feature("eventadmin") in blacklist inbound, node2 and node3 
have not..., node2 installs feature, node3 gets synchronized, node1 not...

When execute the below command on node1 manually:
{noformat}
config:edit org.apache.karaf.cellar.groups; config:propappend 
default.features.blacklist.inbound ,eventadmin; config:update
{noformat}

Then sometimes changed this pid configuration on node1, but often changed this 
pid configuration on node2 or node3.
It seems that the configuration of this pid org.apache.karaf.cellar.groups can 
be synchronized.

(2)would like to test this property "default.features.blacklist.outbound".

Expect that blacklist outbound works as below:
=> one node1 has feature in blacklist outbound, all others have not... if node1 
installs blacklisted feature, it shall not be synchronized.

Execute the below command on node1 manually:
{noformat}
config:edit org.apache.karaf.cellar.groups; config:propappend 
default.features.blacklist.outbound ,eventadmin; config:update
{noformat}
Then same as the above case. should only the configuration on node1 can be 
changed, however often node1 not changed but node2 or node3 would be changed.

(3) If firstly changed the above configuration(blacklist.outbound or 
blacklist.inbound) manually not use the above command, then start three karaf 
instances, then it worked as expected.
