Kernel32 error

[Nisaba]

Hello !

When I use TorSharp, I get this error :

This happens about half the time.
Thank you for your help !

I get this as well. Not sure what the root cause is. Seems to be related to an improperly disposed object but I cannot tell which it is.

From my side, I fixed the issue adding
await Task.Delay(3000);

after

await proxy.ConfigureAndStartAsync();

I have implemented it like this. Which works well until some arbitrary moment when it crashes and burns. with the kernel32 error.

I am not entirely sure why, but I assume the underlying tor proxy service is crashing or closing.

TorServiceExtensions.cs

public static class TorServiceExtensions
{
    private readonly static TorSharpSettings settings = new()
    {
        PrivoxySettings = { Disable = true },
        ZippedToolsDirectory = "./tor",
        ExtractedToolsDirectory = "./tor/extracted",
    };

    public static IServiceCollection AddTorHttpClient(this IServiceCollection services)
    {
        // Register the TorSharp proxy setup as a singleton
        services.AddSingleton<TorSharpProxy>(provider =>
        {
            var clientFactory = provider.GetRequiredService<IHttpClientFactory>();

            var fetcher = new TorSharpToolFetcher(settings, clientFactory.CreateClient());
            fetcher.FetchAsync().GetAwaiter().GetResult();

            var proxy = new TorSharpProxy(settings);
            proxy.ConfigureAndStartAsync().GetAwaiter().GetResult();

            return proxy;
        });

        // Register HttpClient with the Tor proxy
        services.AddHttpClient("TorClient", (provider, client) =>
        {
            client.Timeout = TimeSpan.FromMinutes(2);
            client.DefaultRequestVersion = new Version(2, 0); // Optional: Set HTTP version
        }).ConfigurePrimaryHttpMessageHandler((c) => {
            var proxy = services.BuildServiceProvider().GetRequiredService<TorSharpProxy>();
            var handler = new HttpClientHandler
            {
                Proxy = new WebProxy(new Uri($"socks5://localhost:{settings.TorSettings.SocksPort}")),
            };
            return handler;
        });

        return services;
    }
}

Program.cs

services.AddTorHttpClient();

ConsumingClient.cs

void SomeFunction(string url) {
        var torClient = _httpClientFactory.CreateClient("TorClient");
        var result = await torClient.GetAsync(url);
}
