      Description

      We have a slave running on an HP Itanium host (ver. HP-UX unknown B.11.23 U ia64) where the readlink command does not exists. So when trying to resolve symlinks, slave agent fails with the following error:

            Do you know any equiavlent command in HP-UX that works instead of readlink?

            Well, no ... But why do you need to use it to retrieve artifacts ?

            Hi Kohsuke, i am a colleague of Fulvio.
            jna and jna-posix libraries does not support HP Platform.
            In jna-posix there is a Posix Factory with following method:

            public static POSIX getPOSIX(POSIXHandler handler, boolean useNativePOSIX)
            {
            POSIX posix = null;

            if (useNativePOSIX) {
            try {
            if (Platform.IS_MAC)
            posix = loadMacOSPOSIX(handler);
            else if (Platform.IS_LINUX)
            posix = loadLinuxPOSIX(handler);
            else if (Platform.IS_FREEBSD)
            posix = loadFreeBSDPOSIX(handler);
            else if (Platform.IS_OPENBSD)
            posix = loadOpenBSDPOSIX(handler);
            else if (Platform.IS_32_BIT) {
            if (Platform.IS_WINDOWS)
            posix = loadWindowsPOSIX(handler);
            else if (Platform.IS_SOLARIS)

            { posix = loadSolarisPOSIX(handler); }

            }

            if (handler.isVerbose())
            if (posix != null)
            System.err.println("Successfully loaded native POSIX impl.");
            else
            System.err.println("Failed to load native POSIX impl; falling back on Java impl. Unsupported OS.");
            }
            catch (Throwable t)
            {
            if (handler.isVerbose())

            { System.err.println("Failed to load native POSIX impl; falling back on Java impl. Stacktrace follows."); t.printStackTrace(); }

            }
            }

            Any executable can not be run on this platform using the posix library.

            the closest I come is:

            $ touch aFile
            $ ln -s aFile aLink
            $ file -h aLink 
            aLink:          symbolic link to aFile

            I have the same problem on AIX (5.3 and 6.1). And it's kinda vital for me

            There was a script you may look at: http://unix.derkeiler.com/Newsgroups/comp.unix.shell/2011-12/msg00221.html

            Or if the functionality required measures only to getting the path you can parse the ls -l output. But carefully, because:

            freya:~/tmp/3>touch file
            freya:~/tmp/3>ln -s – file -\>
            freya:~/tmp/3>ln -s – file -\>\ 1
            freya:~/tmp/3>ln -s – -\>\ 1 file1
            freya:~/tmp/3>ls -l
            total 0
            lrwxrwxrwx 1 pooh users 4 Aug 20 11:44 -> -> file
            lrwxrwxrwx 1 pooh users 4 Aug 20 11:44 -> 1 -> file
            rw-rr- 1 pooh users 0 Aug 20 11:44 file
            lrwxrwxrwx 1 pooh users 4 Aug 20 11:45 file1 -> -> 1

            Anyway why do you need to call external program and not do it in java?

            I've added a stopgap fix in this pull request. This doesn't represent a final solution, but might take the heat off things a bit.
