Change Details

Node 6 [was recently transitioned to LTS status](https://github.com/nodejs/LTS), and will be the active LTS release until April 2018. Node 4 will enter maintenance-only mode in April 2017. In the maintenance period until April 2018, Node 4 will continue to receive critical (security) fixes. It will however be fairly out of date in terms of functionality and performance. ## Current status - Node 6 packages are [still in experimental](https://packages.debian.org/search?keywords=nodejs). - The node ecosystem is still widely compatible with Node 4. ## Benefits of upgrading early - We are seeing very significant performance improvements (~50%) for services like RESTBase. Initial Parsoid parser test runs show no peformance changes. - Solid ES6 support. ## Issues with upgrading early - Additional packaging / maintenance work, especially if we get significantly ahead of Debian. ## Compatibility testing - [x] RESTBase, hyperswitch & dependencies - [x] [service-runner](https://github.com/wikimedia/service-runner/pull/135) - [x] [mathoid](https://github.com/wikimedia/mathoid/commit/d3ac8f653d1a6f1cfd2b639c80adeddd426a8e1f) - [x] [ChangeProp](https://github.com/wikimedia/change-propagation/blob/master/.travis.yml) - [x] Analytics Query Service: [merged](https://gerrit.wikimedia.org/r/#/c/318995/), travis enabled, but no test run yet. Based on hyperswitch & doesn't use any binary dependencies, so very unlikely to have any issues. Calling this done -- @gwicke - [x] graphoid -- Manually tested - [ ] kartotherian -- [merged](https://github.com/kartotherian/kartotherian/pull/27). Mapnik's "geojson" plugin is missing (T152131) - [x] citoid -- Does not use travis, manually tested - [x] cxserver -- Does not use travis, manually tested - [x] MCS -- Manually tested - [x] [parsoid](https://github.com/wikimedia/parsoid/blob/master/.travis.yml): [pending](https://gerrit.wikimedia.org/r/#/c/318999/) - [x] Electron render service -- Manually tested by @gwicke - [x] Trending Edits -- Manually tested, OK
