1323559 - Switch to the newer Travis Ubuntu Trusty images

Status: RESOLVED FIXED

(Tree Management :: Treeherder, defect, P2)

Description

[Ed Morley [:emorley]]

Currently on Travis we run:
* linters on their container-based Ubuntu Precise (12.04) image
* the Python tests on their legacy ("group: deprecated") non-container Trusty (14.04) image

They've recently announced a beta for Trusty container images:
https://blog.travis-ci.com/2016-11-08-trusty-container-public-beta/
...so we can stop running the linters on an Ubuntu version that doesn't reflect production.

And the bug that meant we had to use the legacy non-container images has now been fixed:
https://github.com/travis-ci/travis-ci/issues/6928

Which means we can switch to the newer image that already includes mysql 5.6, thereby saving us having to manually install it every time:

In addition to making the linter jobs use Ubuntu 14.04 instead of 12.04 (to match everything else), this trims 40-50s off the sudo-enabled test runs (~20%), making our both our feedback loop and deploys faster :-)

Bug 1323559 - Travis: Switch to the newer sudo-enabled image

The image has received several updates, including now defaulting to
mysql-server 5.6:
https://docs.travis-ci.com/user/build-environment-updates/2016-12-01/
...which means we can skip the 20-25s install of mysql-server-5.6.

The issue with Java on the newer image has now been fixed, so we no
longer need to remain on the older (`group: deprecated`) release.

Bug 1323559 - Travis: Switch the container builds to the new Trusty beta

Travis have just announced a beta for container-based Ubuntu Trusty
builds:
https://blog.travis-ci.com/2016-11-08-trusty-container-public-beta/

This means the linter runs can now run on the same version of Ubuntu
used by the other tests and production. This also reduces runtime since
Travis can skip the glibc patching step required on the older image.

Bug 1323559 - Travis: Don't try to start memcached since already running

The service is running by default, so no need to get Travis to start it,
particularly since Travis adds a `sleep` between each service:

Bug 1323559 - Travis: Move the Elasticsearch readiness check later

The Elasticsearch background process takes up to 8 seconds to start but
isn't required until the tests run, so needn't block the other setup
tasks from running in parallel.
