[jira] [Comment Edited] (QPID-4745) qpidd --port 0 sometimes fails
with 'Can't bind to port 0.0.0.0:49337: Address already in use
(qpid/sys/posix/Socket.cpp:206)'

----------------------------------------------------------------
I think the new qpidd-p0.py has a mistake - the command line it uses is:
qpidd --socket-fd <n> --disable-listen tcp --port <port of fd n>
I think the --port <...> is in error: it seems to try to listen to the same port as the socket it was passed in!
Also I think that for the python system tests it would make more sense to make this a qpidd launching class that is used as part of the test setup. This would create a socket pair and pass one end to the broker and pass the other to the tests to use directly (I think this last part will need a small amount of implementation in the python code).

> Key: QPID-4745
> URL: https://issues.apache.org/jira/browse/QPID-4745
> Project: Qpid
> Issue Type: Improvement
> Components: C++ Clustering
> Affects Versions: 0.22
> Reporter: Alan Conway
> Assignee: Alan Conway
> Priority: Minor
>
> Many of the tests use "qpidd --port=0" to start a broker on an available port.
> Thhis sporadically fails with: Can't bind to port 0.0.0.0:49337: Address already in use (qpid/sys/posix/Socket.cpp:206)
> Many HA tests use --port=0 to start a broker on an available port, but then need to shutdown and restart the broker _on the same port_. This is not safe, on a busy system it is possible for another process to take the port between the time the broker is shut down and the time it is restarted.
