Andrei Dulceanu created OAK-6661:
------------------------------------

             Summary: ResponseDecoder should check that the length of the received blob matches the length of the sent blob
                 Key: OAK-6661
                 URL: https://issues.apache.org/jira/browse/OAK-6661
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: segment-tar, tarmk-standby
    Affects Versions: 1.7.6
            Reporter: Andrei Dulceanu
            Assignee: Andrei Dulceanu
             Fix For: 1.7.8


As already explained in OAK-6659, there can be cases in which deleting the previous spool file fails (Windows) and new (duplicate) content is added under the hood to the old file. This way the persisted blob doesn't match in content and id with the original sent by the server.

By ensuring that the spool file has the same size as the original blob we solve this problem. This check is sufficient, since all the chunks received are individually checked by hash, before appending them to the spool file.
