A couple of weeks ago I moved the uBLAS tests into 'libs/numeric/ublas/test' for consistency with the rest of Boost. Since then the regression test results are filled with a lot of confussing results. I assume this results from the combing of stale result and the new configuration.

Yes, likely.

I assume (and hope) that the next time testers do a 'clean build' things will clear up. This is a lot of work for many testers and there test machines however.

A clean rebuild isn't needed. It's sufficient to delete the stale results. They're located in a single directory (bin/libs/numeric/ublas). A "rm -rf *.test" in that directory is sufficient on Unix systems.

Any ideas how to better make such changes in the future to avoid such confussion?

By announcing that kind of changes on the boost-testing list, for now. I think it would help if there was a way to specify removed tests in the jamfile. The associated action would be to delete the directories containing the test results if they still exist for old tests. After some time (e.g. a couple of weeks), the entries for outdated tests could be removed; alternatively, this step could also be made part of the release preparations. It's not an ideal solution but I think it would be rather easy to implement for those who know Boost.Build better than me. Regards, m
