------------------------------------
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.
