-------------------------------------
Assignee: Mike Matrigali
> In case of checksum error, insure correct error reported to user.
> -----------------------------------------------------------------
>
> Key: DERBY-5002
> URL: https://issues.apache.org/jira/browse/DERBY-5002
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.7.1.1
> Reporter: Mike Matrigali
> Assignee: Mike Matrigali
>
> Checksum errors should always be reported first before doing any other
> checking on the page. Before this fix
> the system would read in the page header first and as a side effect of the
> read do some initial sanity checking which
> for some page corruptions would report errors and never get to the check sum
> check. Checksum errors should
> be reported first as they most quickly and clearly point to disk and system
> crash problems.
> For example in the database corruption reported in DERBY-4894 the following
> error was reported when instead a
> checksum error should have been reported:
> ERROR XSDB0: Unexpected exception on in-memory page Page(103,Container(0,
> 1137))
