Thread: isolationtester's "dry run" mode
This patch adds a -n option to isolationtester. With this option, instead of running the tests, it prints the permutations that would be run. This is very useful for generating test specs which need to remove permutations that are not valid (because they would run a command on a blocked session). Objections? Sample run: $ ./isolationtester -n < ~-/specs/classroom-scheduling.spec permutation "rx1" "wy1" "c1" "ry2" "wx2" "c2" permutation "rx1" "wy1" "ry2" "c1" "wx2" "c2" permutation "rx1" "wy1" "ry2" "wx2" "c1" "c2" permutation "rx1" "wy1" "ry2" "wx2" "c2" "c1" permutation "rx1" "ry2" "wy1" "c1" "wx2" "c2" permutation "rx1" "ry2" "wy1" "wx2" "c1" "c2" permutation "rx1" "ry2" "wy1" "wx2" "c2" "c1" permutation "rx1" "ry2" "wx2" "wy1" "c1" "c2" permutation "rx1" "ry2" "wx2" "wy1" "c2" "c1" permutation "rx1" "ry2" "wx2" "c2" "wy1" "c1" permutation "ry2" "rx1" "wy1" "c1" "wx2" "c2" permutation "ry2" "rx1" "wy1" "wx2" "c1" "c2" permutation "ry2" "rx1" "wy1" "wx2" "c2" "c1" permutation "ry2" "rx1" "wx2" "wy1" "c1" "c2" permutation "ry2" "rx1" "wx2" "wy1" "c2" "c1" permutation "ry2" "rx1" "wx2" "c2" "wy1" "c1" permutation "ry2" "wx2" "rx1" "wy1" "c1" "c2" permutation "ry2" "wx2" "rx1" "wy1" "c2" "c1" permutation "ry2" "wx2" "rx1" "c2" "wy1" "c1" permutation "ry2" "wx2" "c2" "rx1" "wy1" "c1" -- Álvaro Herrera <alvherre@alvh.no-ip.org>
