Commit 1494306 from [~aconway]
[ https://svn.apache.org/r1494306 ]
QPID-4745: Alternative port allocation for tests, instead of 'qpidd --port=0'
qpidd-p0 script binds a new port to a socket using bind(0), and then
execs qpidd using the --socket-fd option to pass the socket to qpidd.
It is intended to replace
/path/to/qpidd --port 0 <args...>
with
qpidd-p0 /path/to/qpidd <args...>
Most tests do not yet use qpidd-p0, they will be updated in a future commit.
Changes:
- Added qpidd-p0
- Fixed qpidd port printing logic: print port only if --port=0, regardless of
--transport.
> 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)'

> 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.
