The QUnit rake task starts a server in test mode. We need a tweak to allow dynamic CSP hostnames in test mode. This tweak is already present in development mode.
To allow CSP to work, the browser host/port must match what the server sees. Therefore we need to disable the enforce_hostname middleware in test mode. To keep rspec and production as similar as possible, we skip enforce_hostname using an environment variable.
Also move the qunit rake task to use unicorn, for consistency with development and production.
- Refactor source_url to avoid using eval in development
- Precompile handlebars in development
- Include template compilers when running qunit
- Remove unsafe-eval in development CSP
- Include unsafe-eval only for qunit routes in development
Plugins can add it via API if they need to use `eval`:
```
extend_content_security_policy(script_src: [:unsafe_eval])
```
See https://meta.discourse.org/t/104243
* FEATURE: allow plugins and themes to extend the default CSP
For plugins:
```
extend_content_security_policy(
script_src: ['https://domain.com/script.js', 'https://your-cdn.com/'],
style_src: ['https://domain.com/style.css']
)
```
For themes and components:
```
extend_content_security_policy:
type: list
default: "script_src:https://domain.com/|style_src:https://domain.com"
```
* clear CSP base url before each test
we have a test that stubs `Rails.env.development?` to true
* Only allow extending directives that core includes, for now
