jsbell@ / dgrogan@ - one more big review? Lots of code removal in this one :)

Overall LGTM...

> Source/WebCore/Modules/indexeddb/IDBBackingStore.cpp:640
> +            return false;

This changes the semantics of this method from "plow ahead in case of error" to "fail the load completely". I don't disagree with this change, but it's orthogonal to the rest of the patch, isn't it? (Also, I'd rather that we just implemented the FIXME if we're going to change the behavior.)

> Source/WebCore/Modules/indexeddb/IDBBackingStore.cpp:1017
> +            return false;

Ditto.

> Source/WebCore/Modules/indexeddb/IDBBackingStore.cpp:1037
>      return indexes;

Should be return true ?

> Source/WebCore/Modules/indexeddb/IDBDatabaseBackendImpl.cpp:56
> +    const RefPtr<IDBBackingStore> m_backingStore;

Not for this patch (because it's consistent with other Operations), but given that we can get to the backing store via the transaction which is passed into perform(), we can probably eliminate this member from this and other Operations.

> Source/WebCore/Modules/indexeddb/IDBDatabaseBackendImpl.cpp:1347
> +    m_metadata.objectStores.clear();

Is this ever called with non-empty m_metadata.objectStores?

> Source/WebCore/Modules/indexeddb/IDBDatabaseBackendImpl.h:108
>      class VersionChangeOperation;

Remove this from IDBDatabaseBackendImpl class while the others are moving out too?

> Source/WebCore/Modules/indexeddb/IDBDatabaseBackendImpl.h:111
>      class VersionChangeAbortOperation;

Ditto?

> Source/WebCore/Modules/indexeddb/IDBObjectStoreBackendImpl.h:46
> +namespace IDBObjectStoreBackendImpl {

May want to add a FIXME indicating that this is temporary, and things in this namespace will move to ... ?

> Source/WebKit/chromium/tests/IDBDatabaseBackendTest.cpp:-50
> -TEST(IDBDatabaseBackendTest, BackingStoreRetention)

Any way to change this test rather than removing it? E.g. creating an IDBTransactionBackendImpl which holds a reference?

Nit: I would say where these are copied from.

> +// FIXME: This should do some error handling rather than plowing ahead when bad data is encountered.

Are there security implications of plowing ahead when bad data is encountered?

> Source/WebCore/Modules/indexeddb/IDBDatabaseBackendImpl.h:69
> +    virtual PassRefPtr<IDBObjectStoreBackendInterface> createObjectStore(int64_t id, const String& name, const IDBKeyPath&, bool autoIncrement, IDBTransactionBackendInterface*, ExceptionCode&)  { ASSERT_NOT_REACHED(); return 0; }
> +    virtual void createObjectStore(int64_t transactionId, int64_t objectStoreId, const String& name, const IDBKeyPath&, bool autoIncrement);

> +    virtual void deleteObjectStore(int64_t transactionId, int64_t objectStoreId);

Should these have OVERRIDE?
