Markus Armbruster 876d061875 tests: Make update robust against variations in PRNG use ... Tests need repeatable pseudo-random numbers to yield repeatable results. Commit 73f1ac8 (v4.3.33) reseeds the PRNG with the count of commands right before executing a command when running_test_suite is on. This doesn't help the update: whenever update code exercised by a test is changed to consume fewer or more PRNs, all subsequent users get different numbers regardless. The ensuing test result changes are extremely tedious to review. To address this problem, reseed the PRNG in the update's two most important loops with the iteration count when running_test_suite. This way, the effect of perturbing the PRN sequence lasts only until the next iteration. There are many more loops, but reseeding in all of them seems impractical. Perturbs test results across the board. Hopefully, that'll happen less frequently now. Signed-off-by: Markus Armbruster <armbru@pond.sub.org>		2017-08-06 19:59:56 +02:00
