[Ironpython-users] Passing Python exceptions in a sandboxed domain

[Cesar Mello]

Hey guys,

I know this is not IronPython specific, but it is causing pain to embbed
IronPython in our product. If someone can help, thanks so much!

I can repro the problem throwing a TypeErrorException from the restricted
appdomain like this:

        // starts with standard Internet Zone sandbox permissions
        var evidence = new Evidence();
        evidence.AddHostEvidence(new Zone(SecurityZone.Internet));
        var permissionSet = SecurityManager.GetStandardSandbox(evidence);
        permissionSet.AddPermission(new
ReflectionPermission(PermissionState.Unrestricted));

        var setup = new AppDomainSetup();
        setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory;
        setup.ApplicationName = "ConsoleScriptHost";

        var domain = AppDomain.CreateDomain(setup.ApplicationName,
evidence, setup, permissionSet, null);

        try
        {
          domain.DoCallBack(delegate
          {
            var x = new
IronPython.Runtime.Exceptions.TypeErrorException("xxx");
            throw x;
          });
        }
        catch (SecurityException ex)
        {
          var m = ex.Message; // why this?
        }
