Travis optimization #2404

Munter · 2018-07-28T14:03:44Z

I've leveraged as much caching on Travis as possible, which have sped up yarn installs and proselint runs by a lot.

I've switched the travis setup to run on the cheap and fast container setup, which means the test start faster.

The lint+build stage runs all linting except proselint, which runs in parallel in a separate container.

The lint+build stage saves build artefacts in a cache.

After the build has succeeded the external link check runs on the build artefacts in a separate container. This is a non-blocking test run to avoid massive blockage of PR's based on external links changing.

After the build has succeeded and if the build is of the master branch, a deploy will be initialized with the cached artefacts from the build in a previous container.

The fetching of the repositories for loaders and plugins, which previously caused our github api usage to exeed the rate limit has now been removed from the build pipeline. Instead it is a script you will run manually as a maintainer or contributor (yarn update-repos) , which will save the updated repos in version control. The build uses that list of repos to fetch the readmes without ever hitting the github api, and thus avoiding the rate limitation.

All of the above means we can increase the number of parallel builds on Travis, which are currently limited to 1. I think 4 is the maximum we can get, which will give us significant improvement on feedback time.

Latest build of this branch: https://travis-ci.org/webpack/webpack.js.org/builds/409489808

Build times are around 5 minutes for the blocking part and 4 minutes for the non-blocking part. I've set travis up to `fast_finish, which should give a green light in Github as soon as the blocking part of the tests are finished.

It worked?

.travis.yml

+      if: branch = master


This condition saves deploy.sh internal condition, right?

I'll clean that up in a bit

.travis.yml

+      script: yarn linkcheck

Why it this one post build? We shouldn't build if this command fails.

We can re-order as we see fit later. Right now I just need to get the pieces working, then we can discuss what the pipeline should do.

This should be revisited. At this point it was already deployed, right?

Yeah, I also forgot that the dist folder is actually not even checked with proselint at all. Just src/content. So this is just useless

Not that this PR merges to rebuild-hyperlink, since the changes there are prerequisites

byzyk · 2018-07-29T10:21:27Z

.travis.yml

+  include:
+    - stage: Build
+      name: Lint and Build
+      before_install: npm install --global yarn


Travis will automatically use yarn once it sees yarn.lock file, we don't need to install it explicitly.

byzyk · 2018-07-29T10:25:23Z

package.json

    "test": "npm run lint",
    "lint": "run-s lint:*",
-    "lint:js": "eslint src --ext .js,.jsx,.md",
+    "lint:js": "eslint src --ext .js,.jsx,.md --cache true --cache-location .cache/.eslintcache",


Nice one! 👍🏽

+
+          await writeFile(fileName, headmatter + body);
+
+          console.log('Generated:', path.relative(cwd, fileName));


Don't mean to sound too picky but perhaps we could add space after Generated: here?

The console logging adds a space between arguments :)

+    fs.writeFile(jsonPath, json, (err) => {
+      if (err) {
+        throw err;

Do you think it will make sense to add some basic logging here, the same as one in fetch-package-readmes script?

That would indeed make sense. I'd prefer if someone else adds that. I'm about to be offline for a week

byzyk · 2018-07-29T10:41:34Z

Awesome work @Munter, can't wait to try this out! I like the idea of not having to fetch GH repos every 5 minutes and it's gonna solve the API limit issue finally 🎉

montogeek · 2018-07-31T10:28:50Z

@jeremenichelli @EugeneHlushko Any feedback? I would like to merge this one.

montogeek · 2018-07-31T10:30:01Z

@Munter There is a cron job that deploys every day, How would this affect it?

Munter · 2018-07-31T16:37:16Z

@montogeek since I kept the script names intact I think there will be no impact on any cron job

montogeek · 2018-07-31T16:52:54Z

@Munter Yep
