Description Anthony Hunter

2013-10-09 14:23:50 EDT

When migrating the storage from Orion 3.0 CompatibilityMetaStore to Orion 4.0 SimpleMetaStore, the end result is the local project location changing on disk from /serverworkspace/A/A/B to /serverworkspace/an/anthony/OrionContent/Project.

As a result I have been deleting the index folder before migration so that new indexes are built.

If you forget and leave the old indexes there, you get a NPE:

java.lang.NullPointerException
	at org.eclipse.orion.internal.server.search.Indexer.indexWorkspace(Indexer.java:144)
	at org.eclipse.orion.internal.server.search.Indexer.indexUser(Indexer.java:130)
	at org.eclipse.orion.internal.server.search.Indexer.run(Indexer.java:288)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53)

We can force index regeneration programmatically by incrementing SearchActivator#CURRENT_INDEX_GENERATION. After that change all servers will get indexes regenerated on startup.

Oops just realized this bug is a few months old. I believe I fixed the symptom (NPE) already. We should make sure index generation is incremented at least once for 5.0 release though.

Yes, I have verified that this NPE no longer occurs.
