when you re-verify or re-classify you run the test so +may have to make it mtr-parsable; if you then put it in this suite, +the developer who will work on this bug in a few weeks or months will +not have to re-do the same download&fix, she/he can instead reuse your +work. +2) Others can see how their own work influences many unsolved +bugs, by running this suite. If they find that they fix a bug in this +suite, we won't later wonder "how come this bug doesn't happen +anymore, what fixed it?". +3) One can also run this suite with certain switches to see how they +influence unsolved bugs: +./mtr --suite=optimizer_unfixed_bugs \ +--mysqld=--optimizer_switch="firstmatch=off" + +Adding tests to this suite +~~~~~~~~~~~~~~~~~~~~~~~~~~ +One test file per bug,
