commit 2ea552e019bd427b5b1709160a6ed7da9dd23fbd Author: Chris Dent <[email protected]> Date: Mon Dec 10 11:22:54 2018 +0000 Add python 3.7 unit and functional tox jobs Without these, if you try to run tox -epy37,functional-py37 you'll get a successful tox run, but no actual tests are run, which is rather misleading. Given the generaly availability of python 3.7 this is a bad thing. Running the tests under python 3.7 identified a few minor tests failures, also fixed here. Each is a result of a change in behavior in python 3.7: * printable unicode changes with a new Unicode 11-based unicodedata package * intentionally raising StopIteration in a generator is now considered a RuntimeError, 'return' should be used instead * an exception message is different beween python 3 and python 2, and the guard for it was mapping python 3.5 and 3.6 but not 3.7. zuul configuration is adjusted to add an experimental job for python 3.7 unit. A functional test job is not added, because we don't have 3.6 yet, and we probably want to get through that first.
