Subject [jira] [Commented] (DERBY-5195) Create tools for browsing the files in the database log directory.

Rick Hillegas commented on DERBY-5195:
--------------------------------------

Hi Kathey,

I agree that it would help tech support if we checked in DataFileReader, ControlFileReader,
and LogFileReader. Together they weigh a little under 60K so I don't think we would significantly
bloat up the engine jar if we checked them into an engine directory. Maybe org.apache.derby.impl.store.tools?
Mike may have some better theory about where to put these tools.

Productizing these tools would be a little chunk of work:

1) Refactor the tools so that they share helper code which is currently duplicated across
them.

2) Wire them into the list of extra classes so that the jar builder puts them into derby.jar.

3) Write regression tests to verify their behavior.

4) Document them in the Tools Guide.

Thanks,
-Rick

> It would be nice to have some tools to examine the contents of the log directory. The
tools should be able to read the files in that directory without disturbing them.
