--------------------------------------
Summary: [Go] Acknowledging a message on a closed receiver results
in a segmentation fault
Key: PROTON-2843
URL: https://issues.apache.org/jira/browse/PROTON-2843
Project: Qpid Proton
Issue Type: Bug
Components: go-binding
Reporter: Patrick Taibel
Assignee: Alan Conway
Using the {{electron}} package when acknowledging messages ({{{}Accept(){}}},
{{Reject()}} or {{Release()}} on a {{{}ReceivedMessage{}}}) a segmentation
fault occurs if the {{Receiver}} was already closed.
This happens because the underlying link of the receiver gets freed which,
according to the docs of {{pn_link_free,}} also frees any unsettled deliveries.
As the actual acknowledgement needs to run in the engine goroutine the check
for an active receiver has to happen inside the {{electron}} package.
I'd suggest adding a check if the receiver is still alive in the injected
function in {{{}func (rm *ReceivedMessage) acknowledge(status uint64) error{}}}.
I plan to do a PR to fix this but it will take a couple of weeks until I get
there as this is a low priority fix on our end.
