AbstractLicenceValidator - Socket Exception in the discoveryHost start method.

[madu020]

In our project, we are testing the AbstractLicenceValidator.

We got an Exception with DiscoveryHost. It was a SocketException.
I have lost the stackTrace of the exception, but, i'm opening an issue to give you the solution that we applied in our project.

To resolve the problem, we have add a new constructor of AbstractLicenceValidator.
This constructor contain a boolean parameter that can enable or disable the discoveryhost.

There is the constructor :

    protected AbstractLicenseValidator(string publicKey, bool enableDiscovery = true)
    {
        LeaseTimeout = TimeSpan.FromMinutes(5);
        LicenseAttributes = new Dictionary<string, string>();
        nextLeaseTimer = new Timer(LeaseLicenseAgain);
        this.publicKey = publicKey;
        SetupDiscoveryHost(enableDiscovery);
    }

The Constructor call this Method :

    private void SetupDiscoveryHost(bool enableDiscovery)
    {
        DiscoveryEnabled = enableDiscovery;

        if (!enableDiscovery) return;

        senderId = Guid.NewGuid();
        discoveryHost = new DiscoveryHost();
        discoveryHost.ClientDiscovered += DiscoveryHostOnClientDiscovered;
        discoveryHost.Start();
    }

So.... In Conclusion, do you think that this solution can be add to your product ?

If yes, can you advise me when this new constructor will be available in the futur nuget package of Rhino.Licensing ?

Thanks to your team!

I can confirm this issue. It happens on a system with highly restrictive network settings.

Here is a stacktrace:

2015-02-10 14:39:05,301 [1] FATAL [ApplicationLoader]   Unhandled exception occurred:

It happens on a German system, therefore the exception description is in German. It translates to: "An invalid argument has been given."

Hang on, I just realized that this is the wrong repo. The issue arises with the version from Nuget. But the version featured on Nuget is actually a fork made by Hadi Eskandari. This is the correct repo: https://github.com/hibernating-rhinos
