Hi, We're (a couple of us here at HP) are in the process of making some changes to better support Ant on HP's OpenVMS operating system. See http://issues.apache.org/bugzilla/show_bug.cgi?id=39359
One of the changes we are making has to do with determining success or failure based on return value. On OpenVMS, a return value of 1 (or an odd value) signifies success, and even numbered return values signify failure. Some of our customers rely on this, while others would like us to act like all the other "Unix-like" platforms. We'd like to make a property available that our customers could set to control the behavior. Are there any guidelines for making up property names? We think it should be called something like os.supportVMSExit, which when set to true would cause the VMS style return values to be used. By default, however, the standard Unix-type return values would be used. At any rate, we have no interest in the actual name/spelling of the property, so we'd like the Ant dev team's advice. Just for completeness, here's what we propose...a simple change in Execute.java to isFailure for this...something like /** Controls whether we honor VMS status or standard Unix exit status **/ private static boolean supportVMSExit = Boolean.getBoolean("os.supportVMSExit"); : : : * Checks whether <code>exitValue</code> signals a failure on the current * system (OS specific). * * <p><b>Note</b> that this method relies on the conventions of * the OS, it will return false results if the application you are * running doesn't follow these conventions. * One notable exception is the Java VM provided by HP for * OpenVMS - it will return 0 if successful (like on any other platform), * but this signals a failure on OpenVMS. On OpenVMS use the boolean * property Os.supportVMSExit to have VMS exit semantics honored. * * @param exitValue the exit value (return code) to be checked. * @return <code>true</code> if <code>exitValue</code> signals a failure. */ public static boolean isFailure(int exitValue) { //on openvms even exit value signals failure; // for other platforms nonzero exit value signals failure return (Os.isFamily("openvms") && supportVMSExit) ? (exitValue % 2 == 0) : (exitValue != 0); } Thanks for your advice!
