arkane-systems / arkane.zeroconf Goto Github PK

I noticed occasionally call to ServiceBrowser.Browse would result in exception being silently thrown, which i only noticed on the debugger in Visual Studio:
Exception thrown: 'ArkaneSystems.Arkane.Zeroconf.Providers.Bonjour.ServiceErrorException' in Arkane.Zeroconf.dll

Exception is being silently dropped in Providers/Bonjour/ServiceBrowser.cs Start(async = true) method.
Because of this.task = Task.Run (() => this.ProcessStart ()).ContinueWith (_ => this.task = null) ;
Task.Run just drops any exceptions thrown by ProcessStart().

Could you please provide a public API that is friendly with async/await that exposes Task as a return value so caller can decide how best to handle exceptions on async calls.
Or at a minimum provide an option to use Synchronous Browse and let caller handle async routing on their own

Hi,
Some new error codes are added to Bonjour service :
you can add them to SerivceError.cs

    BadSig = -65560,
    BadKey = -65561,
    Transient = -65562,
    ServiceNotRunning = -65563,  /* Background daemon not running * /
    NatPortMappingUnsupported = -65564,  /* NAT doesn't support PCP, NAT-PMP or UPnP * / 
   NatPortMappingDisabled = -65565,  /* NAT supports PCP, NAT-PMP or UPnP, but it's disabled by the administrator * /
    NoRouter = -65566,  /* No router currently configured (probably no network connectivity) * /
    PollingMode = -65567,
    Timeout = -65568

Hi,

Thank you for your version of Mono.Zeroconf. Currently i'm using it in an Unity project. But I have an weird bug that is caused by dnssd.dll. On one computer it works fine, but on the other ones it crashes when exploring dns for devices.

dnssd.dll caused an Access Violation (0xc0000005) in module dnssd.dll at 0033:396a2895.

I'm using bonjour 3 on all devices

I was trying to register and then deregister a service, but on de-register the method Dispose hangs and never comes back.
Is there a solution for it?

Analysis:
Problem is, that this.sdRef.Process (); in method ProcessRegister() is blocking, therefore the this.task will never finish. In Dispose this.task?.Wait (); is called which will block the application.
