Dear Miyake-san, Thank you for updating the patch.
> When argc == 2, pgbench assumes that (1) argv[1] is just a number (e.g. > \sleep 10) or (2) argv[1] is a pair of a number and a time unit (e.g. > \sleep 10ms). I see. > So I fixed the problem as follows: > 1) When argv[1] starts with a number, raises an error depending on > whether the time unit is correct or not. > 2) When argv[1] does not starts with a number, raises an error because > it must be an integer. > > With this modification, the behavior for input should be as follows. > "\sleep 10" -> pass > "\sleep 10s" -> pass > "\sleep 10foo" -> "unrecognized time unit" error > "\sleep foo10" -> "\sleep command argument must be an integer..." error > > Is this OK? Please tell me what you think. I confirmed your code and how it works, it's OK. Finally the message should be "a positive integer" in order to handle the following case: \set time -1 \sleep :time -> pgbench: error: \sleep command argument must be an integer (not "-1") Best Regards, Hayato Kuroda FUJITSU LIMITED
