The strict-dynamic CSP directive is supported in all our target browsers, and makes for a much simpler configuration. Instead of allowlisting paths, we use a per-request nonce to authorize `<script>` tags, and then those scripts are allowed to load additional scripts (or add additional inline scripts) without restriction.
This becomes especially useful when admins want to add external scripts like Google Tag Manager, or advertising scripts, which then go on to load a ton of other scripts.
All script tags introduced via themes will automatically have the nonce attribute applied, so it should be zero-effort for theme developers. Plugins *may* need some changes if they are inserting their own script tags.
This commit introduces a strict-dynamic-based CSP behind an experimental `content_security_policy_strict_dynamic` site setting.
Why this change?
As the number of themes which the Discourse team supports officially
grows, we want to ensure that changes made to Discourse core do not
break the plugins. As such, we are adding a step to our Github actions
test job to run the QUnit tests for all official themes.
What does this change do?
This change adds a new job to our tests Github actions workflow to run the QUnit
tests for all official plugins. This is achieved with the following
changes:
1. Update `testem.js` to rely on the `THEME_TEST_PAGES` env variable to set the
`test_page` option when running theme QUnit tests with testem. The
`test_page` option [allows an array to be specified](https://github.com/testem/testem#multiple-test-pages) such that tests for
multiple pages can be run at the same time. We are relying on a ENV variable
because the `testem` CLI does not support passing a list of pages
to the `--test_page` option.
2. Support a `/testem-theme-qunit/:testem_id/theme-qunit` Rails route in the development environment. This
is done because testem prefixes the path with a unique ID to the configured `test_page` URL.
This is problematic for us because we proxy all testem requests to the
Rails server and testem's proxy configuration option does not allow us
to easily rewrite the URL to remove the prefix. Therefore, we configure a proxy in testem to prefix `theme-qunit` requests with
`/testem-theme-qunit` which can then be easily identified by the Rails server and routed accordingly.
3. Update `qunit:test` to support a `THEME_IDS` environment variable
which will allow it to run QUnit tests for multiple themes at the
same time.
4. Support `bin/rake themes:qunit[ids,"<theme_id>|<theme_id>"]` to run
the QUnit tests for multiple themes at the same time.
5. Adds a `themes:qunit_all_official` Rake task which runs the QUnit
tests for all the official themes.
- Remove no-longer-used `commits-widget` and `site_customizations` paths
- Add `/presence/`
- Move from regex to strings. The unanchored regexes were causing unexpected behaviour (e.g. if a topic had the word `assets` in its slug, it would be skipped). When passed strings, mini-profiler uses `String#starts_with?` for comparison
- Add `Discourse.base_path` to ensure proper functionality in subfolder environments
Mini-profiler causes routes to become uncacheable. When using mini_profiler in production, the lack of cache on these routes can have a noticeable impact on performance/rate-limiting.
This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.
This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.
Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.
This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.
Deprecated settings:
* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb
rack-mini-profiler was setting a cookie path of / which was clobbering
the session cookie path of Discourse.base_path.
Fixes some issues when local dev is unable to read or write from/to
the user session, such as during omniauth CSRF checks.
Previously the default stack suppressor in rack-mini-profiler was excluding
the plugin directory.
This made islolating issues more complicated cause you needed to defer to
pp=full-backtrace which is both slow and noisy
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
This provides us with instrumentation missing after rails upgrade
Latest version of rails uses exec_params internally which is no longer
routed to intercepted methods in mini profiler 1.0.0
* Add missing icons to set
* Revert FA5 revert
This reverts commit 42572ff
* use new SVG syntax in locales
* Noscript page changes (remove login button, center "powered by" footer text)
* Cast wider net for SVG icons in settings
- include any _icon setting for SVG registry (offers better support for plugin settings)
- let themes store multiple pipe-delimited icons in a setting
- also replaces broken onebox image icon with SVG reference in cooked post processor
* interpolate icons in locales
* Fix composer whisper icon alignment
* Add support for stacked icons
* SECURITY: enforce hostname to match discourse hostname
This ensures that the hostname rails uses for various helpers always matches
the Discourse hostname

This avoids needing to deal with CORS for loading of the SVG
Note, added the svg- prefix to the filename so we can quickly tell in
dev tools what the file is
