Add py37 to tox.ini

[hairychris]

Blocked by https://github.com/travis-ci/travis-ci/issues/9815 as Travis doesn't currently support Python 3.7 and 3.4 simultaneously.

From the travis issue:

So for now the best thing to do is to have sudo: required just for job with 3.7.0.

Maybe this workaround could get us there without waiting ^ ?

this is not blocking anything. plyvel works with python 3.7 already, and you can pip install it already today. the only thing missing is linux wheels for 3.7

[hairychris]

Sorry I presumed making sure the build works was a requirement to getting these wheels released.

[carver]

this is not blocking anything ... the only thing missing is linux wheels for 3.7

Cool, is there anything blocking the release of the linux wheels?

@hairychris The Travis thread implies that dist: xenial might also be required

[wbolster]

no blockers anymore except some maintainer time and effort. :)

i tried to update libsnappy (embedded in the wheels) to the latest upstream release but ran into some complications... the build system changed to cmake which just requires a few different commands, but cmake is not available by default inside the build environment (docker container).

i fixed all of the above already, and just need to find a bit of time to round it up, make new builds and publish those on pypi.

feel free to kindly remind me in a few days if i haven't gotten around to it by then.

Thanks wbolster!

@hairychris ah, and now 3.4 is busted, which people in that thread experienced too. That's why the final line was (my emphasis):

So for now the best thing to do is to have sudo: required just for job with 3.7.0.

[hairychris]

Yeah I thought that might happen but worth checking, I don't really want to change too much to get around a temporary issue.

[wbolster]

i published plyvel 1.0.5 with python 3.7 wheels on pypi. https://plyvel.readthedocs.io/en/latest/news.html

[wbolster]

i pushed the tox.ini changes in fbfaecdd07126fa7a113a96b6c27ac7099510b42

let's wait for travis to settle before introducing hacks that will quickly turn into technical debt when travis sorts out their infra.

[wbolster]

for those interested: 20d1d2c2ffb43774d415d92d9f80726fb1d5859d contains the build changes i referred to earlier
