When some data must be sent to the endpoint but an error was previously reported, nothing is performed and we leave. But, in this case, the SC is not notified the sends are blocked. It is indeed an issue if the endpoint reports an error after consuming all data from the SC. In the endpoint the outgoing data are trashed because of the error, but on the SC, everything was sent, even if an error was also reported. Because of this bug, it is possible to have outgoing data blocked at the SC level but without any write timeout armed. In some cases, this may lead to blocking conditions where the stream is never closed. So now, when outgoing data cannot be sent because an previous error was triggered, a blocked send is reported. This way, it is possible to report a write timeout. This patch should fix the issue #2754. It must be backported as far as 2.8. |
