What are "_sync:rb" documents?

I’ve walked through the “Resolving Conflicts” documentation have struck the following problems.

  1. The method outlined for creating the conflict from the documentation doesn’t create any documents with the “_sync:rb” problem.

I successfully implemented the algorithm for resolving the conflict and it resolved the conflict for the test scenario from the documentation.

  1. It also detected the conflict for our application and “resolved” it - but it doesn’t seem to do anything about deleting the “_sync:rb” documents. They are still existing within the database and are still causing problems for our application.

  2. There doesn’t seem to be any visible linkage between the “_sync:rb” documents and the application document. They don’t share the same ID or revision numbers. I know it’s the same document by looking at other attributes in the document, but I can’t see how CB is maintaining any linkage between the documents.

I’m still stuck with the same problem of these “_sync:rb” documents cluttering up the database. I could just do a brute-force delete on them, but that seems wrong. Any help appreciated, and thank-you in advance.
