Yikes, good catch. I wonder if it would be possible for the test suite to catch this. I think env--helper would have written a message to stderr, but because we use --exit-code, we can't tell the difference between that and "false". I think we'd have go back to something more like: test_tristate () { bool=$(git env--helper --type=bool --default=true "$1") || eval "error \"$1 is not a bool: \$$1\"" test "$bool" = "true" } ... if test_tristate GIT_TEST_HTTPD then ... use httpd ... fi Not sure if it's worth it. -Peff
