Dirty fields are not correctly applied after serialization and map clearance
----------------------------------------------------------------------------
Key: GORA-120
URL: https://issues.apache.org/jira/browse/GORA-120
Project: Apache Gora
Issue Type: Bug
Reporter: Ferdy Galema
Fix For: 0.3
Dirty fields are not correctly applied in these situations:
-All entries in the map are incorrectly made dirty when a Persistent is
deserialized.
-Also, due to a separate bug all non-map entries that are deserialized are made
dirty too. (This is pure coincidence as the bugs have different causes).
-Finally, when a map is cleared but some entries that are put afterwards are
actually the same as before, it should be noticed as non-dirty. (This happens
in Nutchgora a lot: getInlinks.clear(), getOutlinks.clear(), getHeaders.clear()
etc.).
Because of this a lot of fields are dirty when they in fact are not. It is
never the other way around. Therefore, this bug purely affects performance.
Patch will follow shortly. Let me know if you have any comments.
