This reverts commit 767b49232e.
If anything else (e.g. GTM integration) introduces a nonce/hash, then this change stops the splash screen JS to fail and makes sites unusable.
Browsers will ignore unsafe-inline if nonces or hashes are included in the CSP. When unsafe-inline is enabled, nonces and hashes are not required, so we can skip them.
Our strong recommendation remains that unsafe-inline should not be used in production.
When enabled, the workbox caching logic in the service worker will be replaced with a very simple offline error page. We plan to use this as an experiment to see how it affects performance and stability of Discourse.
This commit also updates a handful of simple adapters which overrode the jsonMode or primaryKey options. These updates are necessary because class fields cannot be overwritten via `EmberObject`'s `.extend()` syntax. These options do not appear to be widely used by themes/plugins.
CI runs on slower machines, so we need to use longer wait times. `Capybara.default_max_wait_time` is automatically reconfigured based on the environment.
JS assets added by plugins via `register_asset` will be outside the `assets/javascripts` directory, and are therefore exempt from being transpiled. That means that there isn't really any need to run them through DiscourseJsProcessor. Instead, we can just concatenate them together, and avoid the need for all the sprockets-wrangling.
This commit also takes the opportunity to clean up a number of plugin-asset-related codepaths which are no longer required (e.g. globs, handlebars)
The `deprecate_column` helper would change its behavior based on the current `Discourse::VERSION`. This means that 'finalizing' a stable release introduces a previously untested behavior change.
Much better to keep it as a deprecation until manual action is taken to introduce the breaking change.
These routes were previously rendered using Rails, and had a fairly fragile 2fa implementation in vanilla-js. This commit refactors the routes to be handled in the Ember app, removes the custom vanilla-js bundles, and leans on our centralized 2fa implementation. It also introduces a set of system specs for the behavior.
Safari has a bug which means that scripts with the `defer` attribute are executed before stylesheets have finished loading. This is being tracked at https://bugs.webkit.org/show_bug.cgi?id=209261.
This commit works around the problem by introducing a no-op inline `<script>` to the end of our HTML document. This works because defer scripts are guaranteed to run after inline scripts, and inline scripts are guaranteed to run after any preceding stylesheets.
Technically we only need this for Safari. But given that the cost is so low, it makes sense to include it everywhere rather than incurring the complexity of gating it by user-agent.
Running Discourse 3.2 stable under Ember 3 will technically be possible, but is only intended as a short-term migration point. This commit adds an admin warning for sites which are using this configuration, to make it clear that themes and plugins are unlikely to support the configuration.
https://meta.discourse.org/t/287211
In a handful of situations, we need to verify a user's 2fa credentials before `current_user` is assigned. For example: login, email_login and change-email confirmation. This commit adds an explicit `target_user:` parameter to the centralized 2fa system so that it can be used for those situations.
For safety and clarity, this new parameter only works for anon. If some user is logged in, and target_user is set to a different user, an exception will be raised.
Some parts of our code (e.g. some types of reviewable) set `topic.category`. In the past this would override the computed property value, but with recent Ember it raises an error. This commit adds a setter which handles the situation cleanly
In normal use, this `text()` getter is never called. However, when running with the Ember inspector, it is eagerly evaluated and hits throws the "not implemented" error in the base class.
This will make it easier to analyze rate limiting in reverse-proxy logs. To make this possible without a database lookup, we add the username to the encrypted `_t` cookie data.
This was used by chat's HTML documentation experiment. That documentation experiment isn't being actively used/updated, but may be revisited in future. Therefore, this commit updates the jsdoc config to remove the custom theme, but keeps it functional (with the default jsdoc theme).
Having separate mobile/desktop templates is something we're moving away from. This commit moves the mobile-specific logic into a conditional in the main colocated template.
Previously it was relying on the `templates/mobile` logic to make this a simple div wrapper on mobile, and a more complex implementation on mobile. This commit colocates the template so it's active on mobile and desktop, but adds an `{{#if` block to explicitly change the behavior.
In Ember, these deprecations are wrapped in an `if(DEBUG)` check, so they are optimized out of the production build. We prefer to keep deprecations in production so that we can collect telemetry and warn theme authors who do not use local development environments.
This commit restores the deprecations as part of our ember-production-deprecations addon.
`window.deprecationWorkflow` does not exist in the server-side pretty-text environment. This commit fixes the check and adds a general spec for deprecations triggered inside pretty-text

* Move Wizard back into main app, remove Wizard addon
* Remove Wizard-related resolver or build hacks
* Install and enable `@embroider/router`
* Add "wizard" to `splitAtRoutes`
In a fully optimized Embroider app, route-based code splitting more
or less Just Work™ – install `@embroider/router`, subclass from it,
configure which routes you want to split and that's about it.
However, our app is not "fully optimized", by which I mean we are
not able to turn on all the `static*` flags.
In Embroider, "static" means "statically analyzable". Specifically
it means that all inter-dependencies between modules (files) are
explicitly expressed as `import`s, as opposed to `{{i18n ...}}`
magically means "look for the default export in app/helpers/i18n.js"
or something even more dynamic with the resolver.
Without turning on those flags, Embroider behaves conservatively,
slurps up all `app` files eagerly into the primary bundle/chunks.
So, while you _could_ turn on route-based code splitting, there
won't be much to split.
The commits leading up to this involves a bunch of refactors and
cleanups that 1) works perfectly fine in the classic build, 2) are
good and useful in their own right, but also 3) re-arranged things
such that most dependencies are now explicit.
With those in place, I was able to move all the wizard code into
the "app/static" folder. Embroider does not eagerly pull things from
this folder into any bundle, unless something explicitly "asks" for
them via `imports`. Conversely, things from this folder are not
registered with the resolver and are not added to the `loader.js`
registry.
In conjunction with route-based code splitting, we now have the
ability to split out islands of on-demand functionalities from the
main app bundle.
When you split a route in Embroider, it automatically creates a
bundle/entrypoint with the relevant routes/templates/controllers
matching that route prefix. Anything they import will be added to
the bundle as well, assuming they are not already in the main app
bundle, which is where the "app/static" folder comes into play.
The "app/static" folder name is not special. It is configured in
ember-cli-build.js. Alternatively, we could have left everything
in their normal locations, and add more fine-grained paths to the
`staticAppPaths` array. I just thought it would be easy to manage
and scale, and less error-prone to do it this way.
Note that putting things in `app/static` does not guarantee that
it would not be part of the main app bundle. For example, if we
were to add an `import ... from "app/static/wizard/...";` in a
main bundle file (say, `app.js`), then that chunk of the module
graph would be pulled in. (Consider using `await import(...)`?)
Overtime, we can build better tooling (e.g. lint rules and babel
macros to make things less repetitive) as we expand the use of
this pattern, but this is a start.

The regen_ember_5_lockfile script was actually just duplicating the ember3 lockfile without changes 🤦♂️. This commit fixes that, and updates the ember-version-enforcement workflow to detect lockfile issues in future.
Consumers should use the default export. This function doesn't work directly (unless you manually construct its arguments) - the default export helper handles all that automatically.
This makes it much easier to see what a production site will look like before launch. The notices return on the next pageload, so there is minimal risk of this affecting visibility of an email configuration problem.
Previously, `addGlobalNotice` would have to be called before the GlobalNotice component was rendered. By using a TrackedArray, we can improve that so that plugins can call the function at any time and the notice will be rendered immediately
It's very unlikely that something will be introduced which works under Ember 5 and not Ember 3. To reduce GitHub actions costs, flakiness, and visual noise, let's cut down the matrix so we're only using Ember 3 for the 'core frontend' job. All others can run under Ember 5.
This commit adds an additional toggle to our safe-mode system. When enabled, it will cause all deprecation messages to become exceptions. This gives admins a way to test their themes/plugins against upcoming Discourse changes without needing to use the browser developer tools.
Now that we're using native `import()`, our main JS bundles might not even be parse-able by older browsers. In that case, `I18n` will never be defined, and so we need to account for that situation in the browser-update code.
We allow HTML in site setting descriptions, so `<code>` was being rendered as HTML instead of text. This commit fixes that, and adds an additional sentence about how to control markdown-authored code blocks.
In modern hljs, languages should be targetted with `lang-` prefixes. These selectors haven't worked in Discourse for a long time, so let's drop them to reduce confusion
It's possible for browser extensions to trigger JS errors and deprecation warnings. That can lead to significant confusion and noise in our logs/metrics. One recent example we've identified is the 'Wappalyzer' extension triggering the `ember-global` deprecation.
This commit will clearly identify these errors/deprecations with a `[BROWSER EXTENSION]` prefix in the console.
Passing through `attrs` is problematic for a few reasons:
1. Connectors could mutate it and cause issues in the parent widget
2. It doesn't provide a clean API boundary. The connector can access all attrs of the widget. As we move towards refactoring the header away from widgets, this may change. Better to explicitly call out the things we expect plugins/themes to access
3. `attrs` is a reserved property for classic components. Passing an argument called `attrs` into a classic component raises a 'computed property override' deprecation error under Ember 3.28, and causes an error in Ember 4+.
Unfortunately this will be a breaking change to the outlet. Fortunately, it was introduced fairly recently and does not have too many users. We will make immediate updates to themes/plugins we are aware of.
Followup to 9cc2b5cc20
This commit refactors the Wizard component code in preparation for moving it to the 'static' directory for Embroider route-splitting. It also includes a number of general improvements and simplifications.

We were previously relying on Ember's 'vendor' bundle to make the jquery global available on the activate_account route. That no longer happens under our Ember 5 build.
This commit updates our activate-account script to remove the need for jquery, so that it works under both Ember 3 and Ember 5 builds.
Using `DiscourseURL.routeTo` with `replaceURL: true` wouldn't cause a true Ember redirect. That meant that the transition source would be be replaced in the browser's history stack, and the 'back' button wouldn't work as expected. Instead, we can use the router service to perform a proper redirect.
We funnel vendored javascript through ember-cli, but that's only used for the testem environment. Therefore, there's no need to minify it in production builds. In my tests, this reduces peak RSS of a production build from 3.53GB to 3.15GB.
Since 4425e99bf9, we no longer ship the template compiler to the client under any circumstances, so this shim doesn't work. Plus, even if it did work, it would trigger the ember-global deprecation and fail under Ember 4+.
We add `Access-Control-Allow-Origin: *` to all asset requests which are requested via a configured CDN. This is particularly important now that we're using browser-native `import()` to load the highlightjs bundle. Unfortunately, user-configurable 'cors_origins' site setting was overriding the wldcard value on CDN assets and causing CORS errors.
This commit updates the logic to give the `*` value precedence, and adds a spec for the situation. It also invalidates the cache of hljs assets (because CDNs will have cached the bad Access-Control-Allow-Origin header).
The rack-cors middleware is also slightly tweaked so that it is always inserted. This makes things easier to test and more consistent.
In development, I sometimes get `nil` `location.absolute_path` values. It looks like this is sometimes expected (https://bugs.ruby-lang.org/issues/10561) so we should fallback to `.path` and add a nil check.
This value is included when generating static asset URLs. Updating the value will allow site operators to invalidate all asset urls to recover from configuration issues which may have been cached by CDNs/browsers.
This commit introduces the scaffolding for us to easily switch between Ember 3.28 and Ember 5 on the `main` branch of Discourse. Unfortunately, there is no built-in system to apply this kind of flagging within yarn / ember-cli. There are projects like `ember-try` which are designed for running against multiple version of a dependency, but they do not allow us to 'lock' dependency/sub-dependency versions, and are therefore unsuitable for our use in production.
Instead, we will be maintaining two root `package.json` files, and two `yarn.lock` files. For ember-3, they remain as-is. For ember5, we use a yarn 'resolution' to override the version for ember-source across the entire yarn workspace.
To allow for easy switching with minimal diff against the repository, `package.json` and `yarn.lock` are symlinks which point to `package-ember3.json` and `yarn-ember3.lock` by default. To switch to Ember 5, we can run `script/switch ember version 5` to update the symlinks to point to `package-ember5.json` and `package-ember3.json` respectively. In production, and when using `bin/ember-cli` for development, the ember version can also be upgraded using the `EMBER_VERSION=5` environment variable.
When making changes to dependencies, these should be made against the default `ember3` versions, and then `script/regen_ember_5_lockfile` should be used to regenerate `yarn-ember5.lock` accordingly. A new 'Ember Version Lockfiles' GitHub workflow will automate this process on Dependabot PRs.
When running a local environment against Ember 5, the two symlink changes will show up as git diffs. To avoid us accidentally committing/pushing that change, another GitHub workflow is introduced which checks the default Ember version and raises an error if it is greater than v3.
Supporting two ember versions simultaneously obviously carries significant overhead, so our aim will be to get themes/plugins updated as quickly as possible, and then drop this flag.
- Update optional-features to tie the `jquery-integration` flag to the current ember version
- Wrap ember-4-specific logic in ember-cli-build with a version check
- Update global-compat.js to add the jquery global if it doesn't exist (i.e. if we're on a modern ember version)

- Skip rendering DModalLegacy when running Ember 5
- Move named outlet inside the DModalLegacy component file
- Exclude that DModalLegacy template from the build when running Ember 5
- Skip LegacySupport version of modal service when running Ember 5
- Add error popup for legacy modals when running Ember 5
