Sometimes, error happen (unknown recipient, server unreachable...) and i want to log them.

Thanks for your help.

JSON Formatter Error When dealing with property-less classes

Class A is defined as:

public class A {}

Serializing to JSON returns a string
"Namespace.A"
But it should really return
{}

Deserializing fails miserably too

ProcessRunner.GetProcessOutputAsync is not working

This is the code being used (From RaspberryIO Playground):

` public bool SetupWirelessNetwork(string adapterName, string networkSsid, string password = null)
{
var payload = "ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev\nupdate_config=1\n";

        payload += string.IsNullOrEmpty(password) ?
            $"network={{\n\tssid=\"{networkSsid}\"\n\t}}\n" :
            $"network={{\n\tssid=\"{networkSsid}\"\n\tpsk=\"{password}\"\n\t}}\n";

        try
        {
            File.WriteAllText("/etc/wpa_supplicant/wpa_supplicant.conf", payload);
            ProcessRunner.GetProcessOutputAsync("ifconfig >> /home/pi/ifconfig.txt");
            //ProcessRunner.GetProcessOutputAsync("sudo pkill -f wpa_supplicant >> /home/pi/Documents/kill_wpa.txt");
            //ProcessRunner.GetProcessOutputAsync("sudo wpa_supplicant", $"-B -D wext -i {adapterName} -c /etc/wpa_supplicant/wpa_supplicant.conf >> /home/pi/Documents/run_wpa.txt");
        }
        catch
        {
            return false;
        }

        return true;
    }`

After a while testing on raspberry, realized the "ProcessRunner.GetProcessOutputAsync" does nothing at all. Used the line "ProcessRunner.GetProcessOutputAsync("ifconfig >> /home/pi/ifconfig.txt");" to be sure and it did not created any file, but command worked on command line.

Am I using this the wrong way?

Terminal is not printing messages when ReadKey is waiting

If the logic has a task writing to the Terminal but the main thread is waiting for ReadKey, the messages are not shown:

Task.Factory.StartNew(async () =>

                while (true)
                {

[Enhancement] Possibility to set data encoding in GetProcessResultAsync

Now the data is decoded using the default coding (for me ANSI). Please add the option to choose another type of encoding. Specifically, it would be great utf-8. (I encountered this when processing the output from ffprobe, which is in utf-8.)

So far, it can be handled by RunProcessAsync. The data can be read as follows:
Encoding.GetEncoding("utf-8").GetString(data).WriteLine();

High CPU usage on RaspberryPi using Terminal

ManualResetEventSlim causes spinwaits (high CPU usage)
Terminal.cs - Lines 21 and 22 need to be changed to:

        private static readonly ManualResetEvent OutputDone = new ManualResetEvent(false);
        private static readonly ManualResetEvent InputDone = new ManualResetEvent(true);

Change DequeueOutputTask to a background (NOT THREADPOOL PLEASE) Thread with BelowNormalPriority. Here are all the changes:

               // Change declaration
               private static readonly Thread DequeueOutputTask;

                // Here we start the output task, fire-and-forget
                DequeueOutputTask = new Thread(DequeueOutputAsync)
                {
                    IsBackground = true,
                    Name = nameof(DequeueOutputTask),
                    Priority = ThreadPriority.BelowNormal
                };

               // Change signature:
               private static void DequeueOutputAsync()

              // wrap the outer loop of DequeueOutputAsync with:
              using (var tickLock = new ManualResetEvent(false))
              {

              // Change await Task.Delay(1) to 
              tickLock.WaitOne(1);

I need this fixed to continue one of my projects.
And you need this fixed to continue the AccessCore project as well

New .csproj with SDK "Microsoft.NET.Sdk.Web" fail to load

Cannot deploy ASP.NET Core project with SSHDeploy which depends on SWAN.

Unhandled Exception: System.ArgumentException: Project file is not of the new .csproj type.
     at Unosquare.Swan.Components.CsProjFile`1..ctor(Stream stream, Boolean leaveOpen)
     at Unosquare.Labs.SshDeploy.Program.Main(String[] args)

It is because the CsProjFile class checks for Sdk="Microsoft.NET.Sdk", and assumes that it is what makes it the new .csproj-format, but there is also Microsoft.NET.Sdk.Web for web projects.

Is that really the only way to check if it is the new csproj-format?

API CopyMemory in kernel32.dll is not supported for this application type. Unosquare.Swan.dll calls this API.

Hi,

we use Embed IO in one of our apps, which uses SWAN. Wenn we try to publish the app to the Windows Store, we get the error "API CopyMemory in kernel32.dll is not supported for this application type. Unosquare.Swan.dll calls this API."

We checked the code for Embed IO and did not found any reference to CircularBuffer() which causes the problem in SWAN:

    [DllImport("kernel32")]
    public static extern void CopyMemory(IntPtr destination, IntPtr source, uint length);

As a workaround for us we code remove the CircularBuffer Class from SWAN and resubmit but this is not a long term solution.

Could you implement a managed alternative and not using the unmanaged Windows API anymore?

Thanks and regards

Guido

Bug in RunProcessAsync?

I'm trying to process the output data from ffprobe. I have a problem processing with RunProcessAsync. The output is duplicated and garbled. Can you look at it, please?

Here is my code:

        private async Task RunTest()
        {
            string output = "";
            string output2 = "";

            var result = await ProcessRunner.RunProcessAsync(
               @"C:\Users\Test\Documents\ff\ffprobe.exe",
               "-v quiet -print_format xml -show_format \"b.mp4\"",
               // A success callback with a reference to the output and the process itself
               (data, proc) =>
               {
                   output = Encoding.GetEncoding("utf-8").GetString(data);
                   output2 += output;
                   Console.WriteLine("Success callback. Length: " + output.Length);
               },
               // An error callback with a reference to the error and the process itself
               (data, proc) =>
               {

               }
              );

            Console.WriteLine("Complete length:" + output2.Length);
            Console.WriteLine(output2);
        }

The console output is:

Success callback. Length: 517
