Attila Magyar updated KNOX-2638:
--------------------------------
Resolution: Fixed
Status: Resolved (was: Patch Available)
> Shiro propererties are missing after topology deployment
> --------------------------------------------------------
>
> Key: KNOX-2638
> URL: https://issues.apache.org/jira/browse/KNOX-2638
> Project: Apache Knox
> Issue Type: Bug
> Reporter: Attila Magyar
> Assignee: Attila Magyar
> Priority: Major
> Time Spent: 1h
> Remaining Estimate: 0h
>
> STR:
> 1. Have an existing topology (test.xml), see if
> blockSemicolon/blockBackslash/blockNonAscii are in the get topology output:
> curl -u admin:admin-password -k -X GET
> [https://localhost:8443/gateway/admin/api/v1/topologies/test]
> | grep blockSemicolon
> <name>main.invalidRequest.blockSemicolon</name>
> 2. Deploy a new topology file (test2.xml)
> {code:java}
> cp ./conf/topologies/test.xml ./conf/topologies/test2.xml {code}
> 3. blockSemicolon/blockBackslash/blockNonAscii are no longer in the orignial
> test.xml output:
> {code:java}
> curl -u admin:admin-password -k -X GET
> https://localhost:8443/gateway/admin/api/v1/topologies/test | grep
> blockSemicolon {code}
> This also causes some flakiness in tests like GatewayAdminTopologyFuncTest.
>
> The reason why these shiro properties are missing is because we only add
> these after a topology deployment to the in memory representation of a
> topology. When we deploy a new topology we also reload all the existing
> topologies but only redeploy the newly added one.
>
> {code:java}
> @Override
> public void reloadTopologies() {
> try {
> synchronized (this) {
> Map<File, Topology> oldTopologies = topologies;
> Map<File, Topology> newTopologies =
> loadTopologies(topologiesDirectory); // <= parse everything from disk
> List<TopologyEvent> events = createChangeEvents(oldTopologies,
> newTopologies);
> topologies = newTopologies;
> notifyChangeListeners(events); // <= this will redeploy the new
> topology and add the shiro properties, but those will be missing from all
> other existing topologies
> }
> } catch (Exception e) {
> // Maybe it makes sense to throw exception
> log.failedToReloadTopologies(e);
> }
> } {code}
>
