Summary: 0001733: LD_LIBRARY_PATH
Description: (rep by George Cox)


One thing which came out of it was that I noticed that LD_LIBRARY_PATH
is not being passed down to the child/worker JVM by the watchdog JVM
when the latter invokes it, but DYLD_LIBRARY_PATH is. Is that
intentional? This means that I have to put my Tibco JNI libraries in
the resin/libexec/ directory which sucks.

Something like this would be handy:

    static Map<String,String> watchdogEnvironment = System.getenv();

    ProcessBuilder processBuilder = new ProcessBuilder(argv);
    Map<String, String> envp = processBuilder.environment();
    envp.put("LD_LIBRARY_PATH",
watchdogEnvironment.get("LD_LIBRARY_PATH"));

        Process process = null;
        try {
            process = processBuilder.start();
        } catch (IOException e) {
            e.printStackTrace();
        }

Hi,

The preferable behaviour is to pass _all_ environment variables from the watchdog process to the child. So this:

    ProcessBuilder processBuilder = new ProcessBuilder(argv);
    processBuilder.environment().putAll(System.getenv());

    Process process = null;
    try {
        process = processBuilder.start();
    } catch (IOException e) {
        e.printStackTrace();
    }


...is better than this:

    Map<String,String> watchdogEnvironment = System.getenv();
    ProcessBuilder processBuilder = new ProcessBuilder(argv);
    Map<String, String> envp = processBuilder.environment();
    envp.put("LD_LIBRARY_PATH", watchdogEnvironment.get("LD_LIBRARY_PATH"));

    Process process = null;
    try {
        process = processBuilder.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
