Jean-Daniel Cryans updated KUDU-2110:
-------------------------------------
Labels: 1.6.0 (was: )
> RPC footer may be appended more than once
> -----------------------------------------
>
> Key: KUDU-2110
> URL: https://issues.apache.org/jira/browse/KUDU-2110
> Project: Kudu
> Issue Type: Bug
> Components: rpc
> Affects Versions: 1.5.0
> Reporter: Michael Ho
> Assignee: Michael Ho
> Priority: Blocker
> Labels: 1.6.0
>
> The fix for KUDU-2065 included a footer to RPC messages. The footer is
> appended during the beginning of the transmission of the outbound transfer
> for an outbound call. However, the check for the beginning of transmission
> for an outbound call isn't quite correct as it's possible for an outbound
> transfer to not send anything in Transfer::SendBuffer().
> {noformat}
> // Transfer for outbound call must call StartCallTransfer() before
> transmission can
> // begin to append footer to the payload if the remote supports it.
> if (!transfer->TransferStarted() &&
> transfer->is_for_outbound_call() &&
> !StartCallTransfer(transfer)) {
> OutboundQueuePopFront();
> continue;
> }
> {noformat}
