> The user guide does not say anything about the exit code of Cactus. I think that if Cactus has a level-0 warning, i.e. an error, then it should exit with a non-zero exit code. Is there a reason to exit "success" in this case?
Further, the test system seems to ignore the fact that Cactus exits with a nonzero exit code. It displays
Cactus exited with error code 1
Please check the logfile...
No files created in test directory
Success: 0 files identical
And in the summary at the end, treats this as a passing test. In this case, there were no test reference files and no files output, because the test does not produce any data, it just aborts if the test fails.
