hidden dependency on bash in test scripts?

  • Next message: Bjarni R. Einarsson: "Re: hidden dependency on bash in test scripts?" in version 1.54 fails on sanitizer.msg-crlf on my system
    (Debian GNU/Linux 3.0 ; sparc64)

    diff shows the following:

    < X-Junk: -e DEFANGED[99] X-Evil-Header: boo

    > X-Junk:  DEFANGED[99] X-Evil-Header: boo

    indicating that CRHACK= in sanitizer.msg-crlf.t is not initialised correctly, because "echo -e" is a bash-specific feature that doesn't work in ash, which happens to be my /bin/sh

    so, I recommend either:

    1) requiring /bin/bash in this test script (as opposed to generic /bin/sh), or

    2) using /bin/echo from GNU sh-utils, or

    3) generating ^M directly:

    #CRHACK=$(echo -e "\rX-Evil-Header: boo") CRHACK="^MX-Evil-Header: boo"

    where "^M" is the actual return character. Ugly but works.
