Astreams error

[Rusty]

I am running a TCPService that when it starts connects to a server (PC).
After handshakes and buffersizes are negotiated (several volleys of successful communication), it gets an Astreams error and I lose my connection.
I've viewed the unfiltered logs, but don't understand what I am seeing.
What seems to be occuring, if this is discernable from the below log?

Can you post the code in Astreams_Terminated ?

 

[Rusty]

Here are both Astreams_Error and Astreams_Terminated:

Sub Astreams_Error
    WeAreConnected = False
   
    If Socket1.IsInitialized Then 
        Socket1.close
    End If
    If Astreams.IsInitialized Then
        Astreams.close
    End If
Fn.logit("Astreams error " & LastException)
    RescheduleService(3000)    'retry in 3 seconds
    If XferFile.Sending OR XferFile.Receiving Then
        XferFile.Initialize                            'reset all transfer flags/filenames        
        CallSub(Main,"MRNDownloadFail")
    End If
End Sub
    
Sub Astreams_Terminated
    WeAreConnected = False
   
    WaitingOnSocket = 0
    IncomingMsgLength = 0 
    IncomingBufferChannel = 0
    IncomingBufferPointer = 0
    If Socket1.Connected Then
        Socket1.close
    End If
    If Astreams.IsInitialized Then
        Astreams.Close
    End If
    XferFile.Receiving = False
    XferFile.Sending = False
    
    ResetIncoming
Fn.logit("  Astreams terminated " & LastException )
    RescheduleService(3000)    'retry in 3 seconds
End Sub

Thanks Erel

At least some of the errors in the logs happen because you are closing an already closed streams.

1. Do not close anything in the Terminated event as it was already closed.
2. Only close AStreams in Error event. Closing it will also close the socket.

Erel, Regarding (1.) in your above post...

B4a-Bridge does a stream close in Update Status, called from _Terminated.

Sub Streams_Terminated
    If Sender <> Streams Then Return
    UpdateStatus(False, True)

Sub UpdateStatus (Connected As Boolean, AllowFurtherConnections As Boolean)
    ConnectedStatus = Connected
    If Connected Then
    Else
        If Streams.IsInitialized Then Streams.Close

It is better to start a new thread instead of bumping an old thread.

Streams.IsInitialized will return False in this case.
