Charles E. Rolke commented on DISPATCH-1878:
--------------------------------------------
Made some progress on this issue. I'm attaching a sequence diagram
[[email protected]|mailto:[email protected]] to show what's going on. This just
a snapshot and not to be considered correct.
* The client has opened the connection, send the data, and closed the
connection before proton sends the PN_RAW_CONNECTION_CONNECTED event.
Chasing the data and the subsequent close through the system is the basic
problem of this Jira issue.
* The pn_raw_connection to the client is closed for read only.
* An outbound connection to the server is opened.
* The message is written to the server
* The server connection gets a CLOSED_WRITE and a CLOSED_READ event
* The message goes over the wire to the server
* The reply comes back from the server
* The server data is either never seen or it is discarded
Still a work in progress

> Project: Qpid Dispatch
> Issue Type: Bug

> Affects Versions: 2.0.0
> Reporter: Fernando Giorgetti
> Assignee: Charles E. Rolke
> Priority: Major

> I have a tcp-echo server running locally through:
> podman run -d --rm --name tcpecho -p 9090:9090 quay.io/skupper/tcp-go-echo
> And I have a router configured with a tcpConnector to localhost at port 9090
> and a tcpListener at port 9999.
> I am able to use nc (netcat) to send data to the tcp-echo directly (port
> 9090) or through
> the router (port 9999), if I run "nc 127.0.0.1 9999" and the send the data.
> But if I run it as: "echo abcd | nc 127.0.0.1 9999" I am not seeing a
> response, but if
> I use port 9090 (original port) instead of 9999 (router tcpListener), then I
> get the
> response correctly.
