Subject [jira] [Commented] (ACCUMULO-1051) Authorizations has inconsistent serialization
Date Thu, 14 Feb 2013 00:00:13 GMT


Kevin Faro commented on ACCUMULO-1051:

Good point ... sorry I am still trying to get my hands around the code.  

Would it be better to sort auths in checkAuths and store the authorizations in sorted order
in the authList?  Then in serialize, just iterate over the authList instead of auths.  It
would take slightly longer for object creation, but then the sort would only happen once.

John ... what class/classes are failing to build?

> The same set of authorizations may not serialize to the same value each time, if specified
in a different order when constructed (like new Authorizations("a", "b") and new Authorizations("b",
"a")), because serialization reproducibility depends on the insert order in the underlying
> So, one could get the following to happen:
> {code:java}
> true == auths1.equals(auths2) && !auths1.serialize().equals(auths2.serialize());
> {code}
