dotnetmq's Issues

Possible issue on non persistent queue

Hi,
time ago I used DotNetMQ on a project (compliments for the amazing job) and have found a possible issue on non persistent queue.

FILE: MDSPersistentRemoteApplicationBase.cs
METHOD: EnqueueMessage(MDSDataTransferMessage message) method
ROW:
//Add message to queue.
_waitingMessages.AddFirst(new WaitingMessage(messageRecord));

As per my understanding this is a LIFO queue, but I think it is more correct to have a FIFO queue, so I fixed it in:
//Add message to queue.
_waitingMessages.AddLast(new WaitingMessage(messageRecord));

Please let me know your feedback about that.

Thank you,
F

Is this a dead project?

I am researching for a solution(MS.Net preferably) that can be used for a customer queue system where each customer gets token as they arrive. One important aspect is to be able to rebuild the tokens in correct order in a system crash. Lot of queue/messaging systems are kind of overkill and using standard Queue/ConcurrentQueue is not adequate.

I feel DotnetMQ may fit the bill but it seems an abandoned project. Is it the case?

I can't start the service.

I have a problem and that is when he tried to start the service he gives me the 1058 system error and he mentions that he can not start the service.

I would appreciate the help.

InvalidOperationException in DotNetMQ halts all communication

Hi.

Recently in my production environment all the machines stopped sending/receiving messages via DotNetMQ. One machine had following exception in logs:

WARN  2018-04-12 15:18:25,028 [22   ] MDS.Communication.MDSRemoteApplication   - Collection was modified after the enumerator was instantiated.
System.InvalidOperationException: Collection was modified after the enumerator was instantiated.
   at System.Collections.Generic.LinkedList`1.Enumerator.MoveNext()
   at MDS.Communication.MDSRemoteApplication.MessageDeliverer.AsynchronMessageControlTimer_Elapsed(Object state)

This happened 3 to 4 times recently and every time one machine has above Dotnetmq logs. The setup is point-to-point in-memory non-persistent.

I checked the DotnetMQ code. Inside method MessageDeliverer.AsynchronMessageControlTimer_Elapsed(), there is a foreach loop trying to modify the collection which is causing this exception. Following is the extraction:

foreach (var connectedCommunicator in _remoteApplication._communicators)
{
    ...
    //Send communicator to end of the _receiverCommunicators list.
    _remoteApplication._communicators.Remove(connectedCommunicator);
    _remoteApplication._communicators.AddLast(connectedCommunicator);
}

Can you please help to describe what this code is trying to achieve. Can you please also help fixing the above code.

Thanks
Abhishek
