 4 | ===========================
 5 | 
 6 | _2018-07-01_: nearly all travis-ci VMs run Ubuntu trusty which ships with
 7 | openssl 1.0.1.  python3.7 [dropped][python3.7-pr] support for end-of-lifed
 8 | openssl versions.
 9 | 
10 | travis-ci has a `xenial` distribution which can be enabled with `dist: xenial`.
11 | The `python: 3.7-dev` virtualenv provided by travis-ci for trusty is still
12 | 3.7a4 which is quite a bit different from 3.7.0 final.
13 | 
14 | deadsnakes provides a backport of python3.7 for ubuntu xenial which can be
15 | enabled using the [travis-ci apt addon][travis-ci-apt-addon].
16 | 
17 | This repository contains a sample `.travis.yml` which installs python3.7 from
18 | deadsnakes and invokes `tox`.
19 | 
20 | The tl;dr magic to enable this:
21 | 
22 | ```yaml
23 | dist: xenial
24 | addons:
25 |   apt:
26 |     sources:
27 |     - deadsnakes
28 |     packages:
29 |     - python3.7-dev
30 | ```
31 | 
32 | It is suggested to use the [travis-ci matrix][travis-ci-matrix] feature to
33 | only install `python3.7` once as the `apt` add on adds a significant amount of
34 | time to the build.  The example `.travis.yml` does this.
35 | 
36 | ### update (2018-07-03)
37 | 
38 | travis-ci has enabled `python: 3.7` on `dist: xenial` so deadsnakes is no
39 | longer necessary:
40 | 
41 | ```yaml
42 |     - env: TOXENV=py37
43 |       python: 3.7
44 |       dist: xenial
45 | ```
46 | 
47 | _update 2018-10-15_: `sudo: required` is no longer necessary
