Pipes missing messages

[philliha]

Very occasionally the pipes miss messages. I believe this is because of the ways the pipes connect after receiving a message. In my pipeclient I have a timeout on the initial connect but none after that one:

private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
      {
          string log = "";
          if (Settings.Default.selLogger == "My Computer")
              log = ".";
          else
              log = Settings.Default.selLogger;
          using (var client = new NamedPipeClientStream(log, System.Environment.MachineName + anglePort.ToString(), PipeDirection.In))
          {
              Console.Write("Attempting to connect to pipe...");
             // client.Connect();
              try
              {
                  client.Connect(2000);
              }
              catch (TimeoutException)
              {
                  return;
              }
              Console.WriteLine("Connected to pipe.");
              using (StreamReader sr = new StreamReader(client))
              {
                  string temp;
                  while (true)
                  {
                      while ((temp = sr.ReadLine()) != null)
                      {
                          Console.WriteLine("Received from server: {0}", temp);
                          if (temp.StartsWith("P"))
                          {
                              filePath = temp.Substring(1);
                              backgroundWorker1.ReportProgress(0);
                          }
                          if (temp.StartsWith("stop"))
                          {
                              backgroundWorker1.ReportProgress(1);
                          }
                          if (temp.StartsWith("halt"))
                          {
                              return;
                          }
                          client.Connect();
                      }
                  }
              }
          }
      }

I think if we mirror this functionality we'll be all set.

Occasionally missing the first clip is still happening, very sporadically. No sort of sequence to it, Joe was doing the same test every time and it happened 2 out of 30ish. Works fine after the first missed clip, you can continue to capture. Seems like it only every happens on the first clip as Joe logged 50 in a row with no issue. Will test further this afternoon.

@philliha yeah, that's what I was noticing too - which is why I was trying to do the first clip before the loop. I might go back to that, especially since you've said that logger switching will require a restart.
