Test Plan

• portlint: OK (looks fine.)
• testport: OK (poudriere: 1200051, armv7, '', python2.7 tested)
• unittest: OK (run=65 failures=0)

Always compare port declarations against the respective upstream source declarations, matching as closely as possible (without being incorrect).

Apparently mock is only a PYTHON_REL < 3300 TEST_DEPENDS [1]

But it might not be (validate/test)
:)

21–22

If it supports 2.6-3.5(+?) why is this limited to 2.7?

23

Package provides end user scripts [1], so this port should be tested and verified to be 'concurrent safe' and made concurrent safe if not.

Concurrent safe means two package installs of the same port for different python versions (eg: py27-foo and py36-foo) do not conflict (each file in common locations is has a unique filename).

See USE_PYTHON=concurrent. It is usually enough.

RUN_DEPENDS sysutils/py-supervisor is limited to 2.7.

[koobs]

If supervisor is an actual (compulsory and version unconditional) dependency and it only supports 2.7, then the dependent package cannot by definition support anything other than 2.7

superlance upstream provides a .travis.yml that tests (apparently) against Python 3.x, and the file contains no special provisions for that Python environment.

My guess at this point (unless I'm missing something?), without explicit evidence to the contrary as to how superlance can work with 3.x while depending unconditionally on a python 2.x only dependency, is that it can't.

However, there are commits fixing tests on Python 3.x [1] and actual Python 3 support commits [2]

I would personally resolve this quandary prior to commit, but i suppose its not a blocker as setting USES=2.7 in the absence of an explanation is technically correctly.

The supervisor master branch [0] supports Python 3.x, but the 3.3-branch [1]
only work with Python 2.x. The latest release of supervisor is 3.3.3 on PyPI:

Then superlance does not "support 3.x" in its current form and USES=2.7 is correct :)

Accepted with previous comment, either way

Nice port!
