Description Michal Tkacz

Build Identifier: 

Bug 330235 introduced backup/restore functionality for MEMStore and DBStore. It would be nice to have the same functionality for Hibernate Store.

According to Eike

"The new export/import mechanism requires at least the implementation of these optional IStore APIs:

org.eclipse.emf.cdo.server.IStoreAccessor.handleRevisions(EClass, CDOBranch, long, boolean, CDORevisionHandler)
org.eclipse.emf.cdo.server.IStoreAccessor.Raw.rawStore(InternalCDOPackageUnit[], OMMonitor)
org.eclipse.emf.cdo.server.IStoreAccessor.Raw.rawStore(InternalCDORevision, OMMonitor)
org.eclipse.emf.cdo.server.IStoreAccessor.Raw.rawCommit(double, OMMonitor)

Eventually plus these:

org.eclipse.emf.cdo.server.IStoreAccessor.Raw.rawStore(byte[], long, InputStream)
org.eclipse.emf.cdo.server.IStoreAccessor.Raw.rawStore(byte[], long, Reader)
org.eclipse.emf.cdo.server.IStoreAccessor.Raw.rawStore(CDOBranch, long, long, String, String, OMMonitor)
org.eclipse.emf.cdo.server.IStoreAccessor.Raw.rawDelete(CDOID, int, CDOBranch, EClass, OMMonitor)"

Reproducible: Always

commit 47d969e972089caf5e58fef905a63180db2ce51d

I think I've fixed the CDORevision-->CDOID bug in WrappedHibernateList.

Then I've implemented the IStoreAccessor.Raw interface for the server import mechanism. Trying to find out now, what methods to implement from it...

commit 6ffdacfc9822b349a3cdbaee1753e68d22eca196

Okay, I've marked the following methods with // TODO:

org.eclipse.emf.cdo.server.internal.hibernate.HibernateStoreAccessor.rawStore(InternalCDOPackageUnit[], OMMonitor)
org.eclipse.emf.cdo.server.internal.hibernate.HibernateStoreAccessor.rawStore(InternalCDORevision, OMMonitor)
org.eclipse.emf.cdo.server.internal.hibernate.HibernateStoreAccessor.rawCommit(double, OMMonitor)

Comment 4 Martin Taal

I implemented the methods proposed by Eike, the backup tests works except for these 2:
featuremap
externalreference

I will leave these two open for now. The featuremap fails because featuremap support in CDO Hibernate does not seem complete, the externalreference is probably a setup question.

Closing.

Featuremap and export of external references now also passed in the testcase. This is available in the 4.2 stream.
