P.S.: Could you make a new release? I just need that critical #37 fix, but it's inconvenient to use my own Neutronium build with CI, for example.

David-Desmaisons · 2017-11-22T23:21:54Z

I will release new nugets this week-end.
From the 2 first stacks, I can see that some updates are done during the closing: Neutronium is called to refresh a binding at a time that the browser has already been closed.
Check if you call Dispose on the HTMLViewControl control on the OnClosing events

o2genum · 2017-11-23T01:01:32Z

Ok, so this is the same thing, something gets updated when the browser's been already disposed. I think all the exceptions are related, thanks.

David-Desmaisons · 2017-11-24T02:15:39Z

Hello @o2genum , I just released version 1.0.1 containing correction for issue #37

o2genum · 2017-11-28T01:49:26Z

After a HtmlViewControl.Dispose() call I can update ViewModel without a problem. The control is blank, of course, but it causes no exception.

But I've found how to get a Chromium.CfxRemotingException:

Start a Neutronium app that has a timer that updates ViewModel every second.
Kill ChromiumFXRenderProcess repeatedly (PowerShell):

While(1) {
Stop-Process -processname ChromiumFXRenderProcess
}

ChromiumFXRenderProcess restarts a few times.
In a few seconds I get a random Chromium.CfxRemotingException.

I catch it like this to prevent the app from crashing:

    public class BindableBase : INotifyPropertyChanged
    {
        private static Logger logger = LogManager.GetCurrentClassLogger();

        public event PropertyChangedEventHandler PropertyChanged;

        protected bool SetProperty<T>(ref T storage, T value, [CallerMemberName] String propertyName = null)
        {
            if (object.Equals(storage, value)) return false;

            storage = value;
            this.OnPropertyChanged(propertyName);
            return true;
        }

        protected void OnPropertyChanged([CallerMemberName] string propertyName = null)
        {
            try
            {   // Don't crash!
                this.PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
            }
            catch (Exception ex)
            {
                logger.Debug(ex);
            }
        }
    }

When Chromium.CfxRemotingException occurs, ChromiumFXRenderProcess won't restart anymore and the HtmlViewControl is blank.

I still don't understand what the users do, though. Probably this is caused by system shutdown or they kill the Chromium process for fun.

It would be good to catch this exception in Neutronium, if possible, and restart the Chromum process, I think.

o2genum · 2017-11-28T02:42:33Z

Ok, sometimes it recovers even after Chromium.CfxRemotingException, sometimes it doesn't.

David-Desmaisons · 2017-11-28T13:47:53Z

Hi @o2genum , thanks for sharing the scenario and working on reproduction. I will work on improving recuperation on CfxRemotingException.

There already exists a mechanism that try to restart Chromium process in case of unplanned failure. It seems that this mechanism needs to be improved

David-Desmaisons · 2017-11-28T16:19:18Z

I was abble to reproduce this unhandled exception with the scenario you mencioned.
I am providing a fix. From what I have seen, your fix in OnPropertyChanged will do the trick before the release of the corrected version.
From my tests, Neutronium is now recovering everytime Chromium process is killed.

jmecosta · 2017-11-28T19:04:51Z

@David-Desmaisons i also get the

An unhandled exception of type 'Chromium.CfxRemotingException' occurred in WindowsBase.dll
Remote connection lost.


Unhandled Exception: Chromium.CfxRemotingException: Remote connection lost. ---> System.IO.EndOfStreamException: Unable to read beyond the end of the stream.
   at System.IO.BinaryReader.FillBuffer(Int32 numBytes)
   at System.IO.BinaryReader.ReadUInt16()
   at Chromium.Remote.RemoteConnection.ReadLoop()

does you fix fixes this one or any CfxRemotingException? some users have also experiencing some random crashes so we can also verify this

…e package

David-Desmaisons · 2017-11-29T01:20:24Z

@jmecosta Well what is your scenario? It will be very usefull if you can share what happens during this crashes. Are they also linked to during system shutdown?

From what we are seeing here, this fix will correct some edge cases when Chromium process is killed most probably during system shutdown.

This is only scenario I am aware of where such an CfxRemotingException exception is not catched by Neutronium. So let me know if this will continue afterthis correction

jmecosta · 2017-11-29T08:07:24Z

The one I got was actually during startup. But I will monitor with the fix. Thanks

@jmecosta Do you application start or system start-up?

jmecosta · 2017-11-29T11:21:32Z

At my application startup. Not system. I got that actually launching under a debug session. But I had reports of the application crashing while using it also. For example when when using more than one neutronium controls in different tabs and swapping between them

David-Desmaisons · 2017-11-29T12:17:02Z

@jmecosta Thanks for the information,
I remenber we discuss your tab solution and the solution was to dispose the Neutronium component when switching tabs.
I am closing this for now. Please re-open an issue with specific scenario if problem persists after this fix.

jmecosta · 2017-11-29T12:34:29Z

Yep, and those are in place. Still it sometime crashes. I will keep an eye on it. Ghay

o2genum · 2017-12-27T01:03:09Z

For me, if still won't recover after a while-kill loop. The view gets blank.

Neutronium - Error - WebView crashed trying recover
Exception thrown: 'System.IO.IOException' in System.Core.dll
Exception thrown: 'System.IO.IOException' in System.Core.dll
Exception thrown: 'Chromium.CfxRemotingException' in ChromiumFX.dll
Exception thrown: 'System.IO.IOException' in System.Core.dll
Exception thrown: 'Chromium.CfxRemotingException' in ChromiumFX.dll

Still no info on what causes it in real use, though.

Is there a way to reload it manually?

David-Desmaisons · 2017-12-27T15:01:01Z

@o2genum , if you are seing this trace:
Neutronium - Error - WebView crashed trying recover
that means that Neutronium is trying to reload the View.
If the views get blanks and did you display anything that means that the recover process failed.
It will be great to identify better such scenario so that the recovery process can be improved.

Is there a way to reload it manually?
You can try something like setting the datamodel to null and then back to the original value.
