angela commented on OAK-4599: ----------------------------- [~frm], not that i would like that but i really don't see another way to reproduce the issue in oak. May I kindly ask you to review the proposed refactoring... once we are good here, I think step 2 is somewhat redundant as we can't discuss alternative approaches to fixes this if we cannot reproduce the original issue... so only 3 and 4 would be left. > SecurityProviderRegistration fails to update config param of > SecurityConfiguration(s) > ------------------------------------------------------------------------------------- > > Key: OAK-4599 > URL: https://issues.apache.org/jira/browse/OAK-4599 > Project: Jackrabbit Oak > Issue Type: Bug > Components: core > Affects Versions: 1.1.8, 1.2.16, 1.0.32, 1.4.5, 1.5.6 > Reporter: angela > Assignee: angela > Attachments: OAK-4599_test_1_2.patch, OAK-4599_test_trunk.patch, > OAK-4599_trunk_var2.patch > > > h4. Steps to reproduce > - start Oak repository in OSGi setup with additional required (custom) > services that are passed to various security modules as config parameter such > as e.g. {{RestrictionProvider}}, {{UserAuthenticationFactory}}, > {{AuthorizableNodeName}} or {{AuthorizableActionProvider}} > - verify that the security setup contains the custom configurations > - now, force a re-registration of the {{SecurityProvider}} by changing a > referenced/required security service, which is not associated with the custom > configuration as specified in the initial setup > - once completed any {{SecurityConfiguration}}, that is associated with > custom configuration params such as the examples listed above will no longer > have the corresponding params set. > h4. Finding step by step > - {{SecurityProviderRegistration}} waits until all configured required > service references have been registered and all non-dynamic references have > been resolved. > - Once everything is resolved the {{SecurityProviderRegistration}} looks as > expected including all configuration parameters > - {{SecurityProviderRegistration}} now starts creating a new > {{SecurityProvider}} instance with all the unary and required module > references. > - During this step it also calls {{initializeConfiguration}} in order to have > the modules populated with additional stuff from the > {{SecurityProviderRegistration}} and it's here we have IMHO a bug: The > {{initializeConfiguration}} will push the params from > {{SecurityProviderRegistration}} to the {{SecurityConfiguration}}, while at > the same time trying to merge params defined directly on the > {{SecurityConfiguration}}. > h4. Explanation > In a plain Java setup as it was initial designed for the > {{SecurityProviderImpl}}: The 'local' params from {{SecurityConfiguration}} > need to take precedence over those present in {{SecurityProvider}}. > However, In our new, pure Osgi setup, where there is no such > mixed-param-setup, we would need a mandatory overwrite of e.g. > {{RestrictionProvider}} (s) or {{AuthorizableActionProvider}} (s), because > the _old_ values in the {{SecurityConfiguration}} had not been provided by > it's own config but as a matter of fact refer to the old values of the > {{SecurityProviderRegistration}}, which got unregistered and thus are stale > service references. > h4. Potential Fixes > In any case we must have a unit-test that illustrates the problem and allows > us to verify that whatever fix we apply actually addresses the problem. I > will try to provide that today. > h5. Variant 1 > Looking back my feeling is, that we should have moved all those extra-params > that get pushed to the {{SecurityConfiguration}} as references to the > modules. Not sure if/how that is feasible at the current state without > risking too many compatibility issues and regressions. > h5. Variant 2 > Since we no longer have a mixed java/osgi setup since the introduction of the > {{SecurityProviderRegistration}} and removed the OSGi-annotations from the > old (now pure java) {{SecurityProviderImpl}}, we might consider just changing > the following call in {{SecurityProviderRegistration}} from: > {code}base.setParameters(ConfigurationParameters.of(parameters, > base.getParameters()));{code} > to > {code}base.setParameters(ConfigurationParameters.of(base.getParameters(), > parameters));{code} > and thus actually doing what we intend to do: replace the existing entries in > the {{SecurityConfiguration}} by the new ones. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
