Unable to save document edited during ChangeTracking

[MikeGoldsmith]

This integration test fails:
BucketContextTests.SubmitChanges_WhenDocsAreModified_DocumentIsMutated
with the error:
Couchbase.Linq.CouchbaseConsistencyException : Data exists for key

The test enables ChangeTracking, retrieves and updates a document then calls SubmitChanges(). This should update the stored document, but is instead throwing CouchbaseConsistencyException which indicates the result's status was "KeyExists". See here.

I don't think a KeyExists response code should be interpreted as consistency issue.

I believe that for inserting a document I was treating KeyExists as a consistency error to catch cases where you're inserting a new document and that document already exists. Is the SDK also returning KeyExists for updates to existing documents?

[MikeGoldsmith]

I would have expected it to be "Success"

@MikeGoldsmith

On my machine this test is currently passing.

1. Using current "master" branch (with SDK 2.3.10)
2. Using Server 4.6.0-3453 Enterprise Edition (build-3453) (Developer preview released at Connect)

My cluster is two 4.5.1-2844 Enterprise Edition (build-2844) nodes. I'll check to see if I get the same on 4.6.0.

[MikeGoldsmith]

Hmm, the test also passes for me when using 4.6.0-3558 Enterprise Edition (build-3558).

@jeffrymorris @brantburnett Can one of you verify if you see this test fail with server 4.5.1 please? It may be a 4.5.1 server bug.

@MikeGoldsmith @brantburnett - i have a 4.5.1 cluster I can test against.

@jeffrymorris have you had any luck reproducing this bug?
