Mahadev konar updated ZOOKEEPER-38:
-----------------------------------
Attachment: ZOOKEEPER-38_8.patch
here is an updated patch. I cleared the patch with nice javadocs and more
testing. Fixed a few bugs i found during the testing.
bq. In ZooKeeperServerMain you changed from using the configuration methods
to putting everything in the constructor. I think we should stick with the
configuration methods. (This same comment applies to Leader and QuorumPeer
i am not sure abt this. did i remove something?
bq. In FileSnapLog.deserialize() if the snapshot is bad, you should try an
earlier snapshot. (We should add a test case for this)
you are right... i would rather have it as another jira since this would be an
improved over our earilier versions and would help getting this in without more
delay :).
bq. SnapLog should really be called Snapshot since it does not have a log
component
done.
bq. In FileTxnLog.getLogFiles() you should add a comment to the first (fzxid >
logZxid) check that you are taking advantage of the fact that the files are
sorted, so the last time this condition is true will be for the log file that
has snapshotZxid.
done.
bq. In FileTxnLog.getLastLoggedZxid() the comment is a bit unclear. I think
this method will also have a problem if the last logfile consists of a single
corrupt entry.
done... thats is true... I will open another jira for this as well.
bq. In FileTxnLog.truncate() you may need to delete files as well if the zxid
you are truncing to is in a log file before the last file
done.
bq. TxnLogCompletion is not used and should be removed
done.
bq. The Util class has some methods that are not used that should be removed.
done.
