Artifact archiving from an ssh slave fails if symlinks are present

    • Slave must be a "Unix via SSH" slave. I suspect the master must be Unix-based also. I tested with both the master and slave on Linux.

      When archiving artifacts from a job executed on a "Unix via SSH" slave, if a symlink is present and archived before its target, the archiving will fail. It looks like the master is trying to chmod the local symlink (because it has executable permissions stored in the tar used to do the remote copy), but that fails because the target doesn't exist yet, and the exception aborts the archiving. I think the solution is to just not chmod symlinks, since they don't have modes of their own. This was a regression from 1.455 to 1.456. I suspect the fixes for JENKINS-9118 are the cause.

      To reproduce this problem, install the Jenkins master on a Linux machine and add a "Unix via SSH" slave that is also a Linux machine. Create a job with the following build script:

      rm -rf stuff
      mkdir stuff
      cd stuff
      touch zzfile
      ln -s zzfile aafile
      ln -s zzfile bbfile

      Restrict this project to build on the slave. Set up archiving for "stuff/*". Run the job. The job will complete successfully, but archiving will abort partway though with a stack trace in the console.
