[jira] Commented: (DERBY-3045) Write a tool to do a binary search of past trunk builds to find the source of regressions

Daniel John Debrunner commented on DERBY-3045:
----------------------------------------------

What's a "trunk jar from a previous release"? Releases are off branches, not the trunk?

Also why keep any jars around, the jars can be re-built from a codeline at the correct revision? In some cases the regression might have been caused by one of three changes included in a set of built jars, so the built jars may not always lead to the specific change.

> Often we have to backtrack to find the source of a regression.   It would be useful to have a tool which would run a java program against archived builds and do a binary search for the build that caused the failure.  Trunk builds for the current release are stored at http://dbtg.thresher.com/derby/bits/trunk/ but in order for the tool to be most useful we would need to start keeping the trunk jars from previous releases.
