-----------------------------------
Summary: local-idle-timeout is detected but on_transport_error
callback is not called
Key: PROTON-2101
URL: https://issues.apache.org/jira/browse/PROTON-2101
Project: Qpid Proton
Issue Type: Bug
Components: cpp-binding, proton-c
Affects Versions: proton-c-0.29.0, proton-c-0.28.0, proton-c-0.27.1,
proton-c-0.27.0, proton-c-0.26.0, proton-c-0.25.0
Environment: Windows, 64-bit, TLS, Visual Studio 17 C++
Reporter: Bajan Fella
Attachments: simple_recv.cpp
I am running 0.25 and I see an issue where the local-dle-timeout is being
detected but the on_transport_error callback is not being called. As a result
sometimes when my application experience temporary network issues it cannot
recover. This is a release blocker for me.
I have all my TRACE flags enabled and I am seeing
->[000001661BD6BDF0]:ERROR amqp:resource-limit-exceeded local-idle-timeout
expired
->[000001661BD6BDF0]:0 -> @close(24) [error=@error(29)
[condition=:"amqp:resource-limit-exceeded", description="local-idle-timeout
expired"]]
When I caught this issue in the debugger I can see the PN_TRANSPORT_TAIL_CLOSED
event but never receive the PN_TRANSPORT_CLOSED event.
To reproduce, I took the \qpid-proton-master\cpp\examples\simple_recv.cpp from
the 0.29.0 repo and modified it so I can connect to my server which is setup
for TLS. Please see attached sample code.
Once I connect I then use Clumsy ([https://jagt.github.io/clumsy/index.html])
to slow down/throttle/drop some packets on the port. For example, if my server
is listening on port pxxx at ipx.ipx.ipx.ipx. I use
(((ip.DstAddr=ipx.ipx.ipx.ipx) and (tcp.DstPort=pxxx)) or
((ip.SrcAddr=ipx.ipx.ipx.ipx) and (tcp.SrcPort=pxxx))) as a filter in Clumsy
After a minute our so I get the expected output in the trace and netstat -ano |
finsstr /c:pxxx shows that the TCP connection is closed but I did not receive a
transport_error or transport_close
