node: Create a locker for multiple Console.Write

[shargon]

Currently we can receive from plugins some outputs that can be mixed with the entered command. We should be able to send these results together.

Related to neo-project/neo-node#905 (comment)

We need somthing like:

 public static class ConsoleHelper
    {
        public static readonly object Locker = new();
...
        public static void Info(params string[] values)
        {
            lock (Locker)
            {
                var currentColor = new ConsoleColorSet();

                for (int i = 0; i < values.Length; i++)
                {
                    if (i % 2 == 0)
                        InfoColor.Apply();
                    else
                        currentColor.Apply();
                    Console.Write(values[i]);
                }
                currentColor.Apply();
                Console.WriteLine();
            }
        }

In order to allow lock(ConsoleHelper.Lock){ ... multiple out ... }

Wouldn't it be better to do this on neo-core

namespace Neo
{
    public delegate void LogEventHandler(string source, LogLevel level, object message);

    public static class Utility
    {
        internal class Logger : ReceiveActor
        {
            public Logger()
            {
                Receive<InitializeLogger>(_ => Sender.Tell(new LoggerInitialized()));
                Receive<LogEvent>(e => Log(e.LogSource, (LogLevel)e.LogLevel(), e.Message));
            }
        }

        public static event LogEventHandler Logging;

        public static Encoding StrictUTF8 { get; }

        static Utility()
        {
            StrictUTF8 = (Encoding)Encoding.UTF8.Clone();
            StrictUTF8.DecoderFallback = DecoderFallback.ExceptionFallback;
            StrictUTF8.EncoderFallback = EncoderFallback.ExceptionFallback;
        }

        public static object ConsoleLock { get; } = new(); // Add this line
        public static void Log(string source, LogLevel level, object message)
        {
            lock (ConsoleLock) // Add this line
                Logging?.Invoke(source, level, message);
        }
    }
}

Because the plugin you were talking about uses, Utility.Log

I did find this in neo-cli; syncRoot its for locking so you can sync root of console.

[cschuchardt88]

this can be closed. has one built-in

Where is syncRoot?

[cschuchardt88]

It is in neo-cli
https://github.com/neo-project/neo-node/blob/da786195cfb6d70236bb37611c37d7016bbc3aae/neo-cli/CLI/MainService.Logger.cs#L29

[shargon]

But is private, how can be used in neo-project/neo-node#905 ?

[cschuchardt88]

Its a partial class

https://github.com/neo-project/neo-node/blob/da786195cfb6d70236bb37611c37d7016bbc3aae/neo-cli/CLI/MainService.cs#L41

[shargon]

But we also use Console outside this repo, in plugins, we should have access to it

[cschuchardt88]

We can make it public and do something like #2995
