Subject [jira] [Commented] (OAK-3146) ExternalLoginModuleFactory should inject SyncManager and ExternalIdentityProviderManager
Date Tue, 28 Jul 2015 18:31:04 GMT

    [ https://issues.apache.org/jira/browse/OAK-3146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14644806#comment-14644806

Tobias Bocanegra commented on OAK-3146:

I would just remove the performance label and fix the issue w/o benchmark. from the description
and code-flow it is obvious that it can inconsistent situations when the login module is initialized
during the logout phase. so not directly performance related.

> {{ExternalLoginModule}} currently performs a lookup of {{SyncManager}} and {{ExternalIdentityProviderManager}}
in initialize call which performs service lookup using ServiceTracker. Doing a service lookup
in critical path would have adverse performance impact. 
> Instead of performing the lookup {{ExternalLoginModuleFactory}} should track the two
manager instances and pass them to {{ExternalLoginModule}}. This would ensure that expensive
operation like service lookup is not performed in critical path
