Previously workbox JS was vendored into our git repository, and would be loaded from the `public/javascripts` directory with a 1 day cache lifetime. The main aim of this commit is to add 'cachebuster' to the workbox URL so that the cache lifetime can be increased.
- Remove vendored copies of workbox.
- Use ember-cli/broccoli to collect workbox files from node_modules into assets/workbox-{digest}
- Add assets to sprockets manifest so that they're collected from the ember-cli output directory (and uploaded to s3 when configured)
Some of the sprockets-related changes in this commit are not ideal, but we hope to remove sprockets in the not-too-distant future.
By default, the Sprockets DirectiveProcessor introduces a newline between possible 'header' comments and the rest of the JS file. This causes sourcemaps to be offset by 1 line, and therefore breaks browser tooling. We know that Ember-Cli assets do not use Sprockets directives, so we can totally bypass the DirectiveProcessor for those files.
We're using v3 of Sprockets, which is no longer supported - upstreaming a fix will be difficult. Long term, we intend to move away from sprockets.
This patch removes some of our freedom patches that have been deprecated
for some time now.
Some of them have been updated so we’re not shipping code based on an
old version of Rails.
When plugin spec is evaluated for the first time, it took 30 seconds to run:
```
rm -rf tmp/* && LOAD_PLUGINS=1 be rspec ./plugins/discourse-solved/spec/requests/topics_controller_spec.rb
```
Applying sprocket patch in test environment solves that issue
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
