             Summary: Fedora 28 python3-only test issues
                 Key: DISPATCH-1098
                 URL: https://issues.apache.org/jira/browse/DISPATCH-1098
             Project: Qpid Dispatch
          Issue Type: Bug
          Components: Tests
    Affects Versions: 1.2.0
            Reporter: Chuck Rolke


Building a Fedora 28, python-3-only (no python 2), proton and dispatch leads to some test issues.
 * `which python` is empty
 * `which unit2` is empty

h4. Define python

CMake finds python OK and builds proton and dispatch with the correct python version. But the tests don't work. _python_ appears to be a python 2 construct. In a python 3 system the executable is installed as python3. Python can be defined with the alternatives command

{{alternatives --install /usr/bin/python python /usr/bin/python3 1}}
h4. Define unit2

The self test runner in dispatch expects an executable named _unit2_. _Unit2_ is a python 2 executable and in python 3 the equivalent program is named _unit2-3_. The dispatch build scheme should always use _unit2_ and thiis can be accomplished for python 3 with:

{{alternatives --install /usr/bin/unit2 unit2 /usr/bin/unit2-3 1}}
h4. Proposal

Dispatch self test should use naked _python_ and _unit2_ commands. An check in the dispatch build could disable tests and warn about them being disabled similar to how a missing unittest2 is handled. See https://issues.apache.org/jira/browse/DISPATCH-919
