1. `addRawTemplate` is called too early for deprecation handlers to process its deprecation call, so toggle the hbr flag directly
2. move the deprecation handler to an initializer so that other (non-template) calls are always handled
3. move the debug logging to the handler
This commit modernizes the post menu by migrating it from the existing widget-based implementation to Glimmer components. This transition aims to improve the maintainability, performance, and overall developer experience.
It also introduces a new DAG-based transformer API for customizations that aims to be more flexible than the widget base one.

Template overrides have been advised against for a long time, and are increasingly hard to maintain as Discourse's development accelerates. This commit officially deprecates this customization method, which will be removed in the not-too-distant future (likely in the first half of 2025).
We are moving away from the mobile-specific template pattern in favor of logical `{{#if}}` statements. This brings us closer to a standard Ember app, makes testing easier, and reduces duplicate code.
This commit includes some minor refactoring in the resolver & component-templates initializer, so that the mobile lookups happen on desktop, without actually being used. This allows us to print the deprecation message consistently, to improve visibility to developers.
There is a risk of overriding and then deleting a prop of the context in case of a naming clash between localName and that prop, e.g.
```js
class Test {
item = "foo";
items = [1, 2];
}
const template = `
{{#each items as |item|}}
{{item}}
{{/each}}
`;
const compiledTemplate = compile(template);
const object = new Test();
// object.item === "foo"
const output = compiledTemplate(object, RUNTIME_OPTIONS);
// object.item === undefined
```
…but I think we can accept this risk and just be careful.`#each` isn't widely used in hbr anyway (as proven by the other long-standing and recently fixed bug) and hbr is on its way out anyway.
This upgrade is designed to be fully backwards-compatible. Any icon names which have changed will be automatically remapped to the new name. For now, this will happen silently. In future, once core & official themes/plugins have been updated, we will start raising deprecation errors to help theme/plugin authors update their code.

This message indicates broken behavior, so it should be an error rather than a warning.
An early-return is added, so that we don't even attempt to make the modification. This will make the behavior consistent, and easier to understand.
Also updates the normalization logic to use the resolver's own logic. This will handle all sorts of normalization in addition to our deprecations.
e.g. we map `controller:composer` to `service:composer` in resolver lookups. So, when doing the cache check in modifyClass, we need to check against the normalized name, not the deprecated name.
* `@ember/owner` instead of `@ember/application`
* `discourse-i18n` instead of `I18n`
* `{ service } from "@ember/service"` instead of `inject as service`
The AdminPlugin JS model uses a similar pattern to chat models,
where it is a plain JS class manually converting provided
snake_case attributes from the serializer to JS camelCase.
However this doesn't work when it comes to using `add_to_serializer`
in plugins since core does not know about these new attributes.
Instead, we can use a JS function to convert snake_case to camelCase
and use that when initializing AdminPlugin. This commit also moves
similar functions to a new case-converter.js file in
discourse-common/lib.

Inline the helper functions, avoid creating and then immediately destructuring arrays, use complete strings instead of string interpolation, Map instead of a pojo.
`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.

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.
This commit ports the feature by @chapoi that was
previously a theme component in core.
A new post_menu button, copyLink, is added and used
as the default instead of share.
copyLink, on desktop, will copy the link of the post
to the user's clipboard and show a nice 'lil animation.
On mobile the native share menu will be shown.
If site owners want the old behaviour back, they just
need to change the post_menu site setting to use
the share button instead of copyLink.
This discourse-common decorator was dependent on the core app, hence creating a circular reference that was breaking the embroider upgrade. (see: #24391)
- Add prefixes to Ember deprecations (previously was just Discourse deprecations)
- Allow logic to work in tests (where window.Discourse is not defined)
- Detect `{plugin}_tests.js` files
- Optimise dev/test regex logic out of the production build using `if(DEBUG)`
Now that core has a file structure and default imports, Ember's resolver can load helpers lazily. So we can remove the lazy loading, and helpers in ember templates will continue to work. This should provide a slight performance improvement for initial boot.
However, there is a slight complication: some of our helpers are also registered with our Raw Handlebars system as a side-effect of loading the module. Therefore, this commit adds a `helperMissing` helper to our RawHandlebars system. This looks up the helper by name in the ember resolver, which triggers the relevant module to be evaluated, and the raw helper to be registered as a side effect.
For backwards-compatibility, plugin and theme helpers continue to be eagerly evaluated. Once the `discourse.register-unbound` deprecation is resolved, we can safely remove this eager loading.
`registerUnbound` was present for legacy reasons when using helpers in raw-hbs and has been replaced by `registerRawHelper`.
For new helpers used only in classic ember template, exporting a default function from `helpers/*.js` is recommended.
This change also means that all existing helpers will be available to import in `gjs` files.

As of #23867 this is now a real package, so updating the imports to
use the real package name, rather than relying on the alias. The
name change in the package name is because `I18n` is not a valid
name as NPM packages must be all lowercase.
This commit also introduces an eslint rule to prevent importing from
the old I18n path.
For themes/plugins, the old 'i18n' name remains functional.
`escape` from `pretty-text/sanitizer` is a re-export of the same
function defined in `discourse-common`. Updating the import paths
across the codebase to use the `discourse-common` import path.
`escape` is a rather simple function that can be accomplished with
a regular expression in `discourse-common`.
On the other hand, the remaining parts in `pretty-text/sanitizer`
has a lot of code, PLUS it depend on the rather heavy "xss" NPM
library.
Currently, most of the consumers of `pretty-text/sanitizer` are of
the `{ escape }` varient. This is resolved by this PR.
The remaining usages are either:
1. via/through `PrettyText` which is essentially gated behind
loading the markdown-it bundle, OR
2. via `sanitize` from `discourse/lib/text`
I believe we may ultimately be able to move all the usages to behind
the markdown-it bundle (or, equivilantly, set up another lazy bundle
for `sanitize`) and be able to shed the sanitization code and the
"xss" library from the initial page load.
`discourse/lib/text` also defines a `sanitizeAsync` which is gated
behind loading the markdown-it bundle.
Looking through the usages of `sanitize`, I believe most of these
can be safely switched to use `sanitizeAsync`, in that they are
already in an asynchrnous path that handles a server response. Most
of them are actually rendering a piece of server-generated HTML
message as flash message, so I am not sure there really is value in
sanitizing (we should be able to trust our own server?), but in any
case, code-wise, they should already be able to absorb the async
just fine.
I am not sure if `sanitize` and `sanitizeAsync` are actually API
compatible – they both take `options` but I think those `options` do
pretty different things. This is somethign for another person to
investigate down the road in another PR.
According to `all-the-plugins`, `discourse-graphviz` also import
from this location, so perhaps we should PR to update. That being
said, it doesn't really hurt anything to keep the alias around for
a while.
- Introduces a `deepFreeze` helper to block any mutations to the current-user fixture
- Add `cloneJSON` to any places which were previously causing mutations
Normally, modules defined under `blah/index` can be imported as `blah`. This is also true of Ember resolver lookups - `<MyComponent />` should resolve to the same as `<MyComponent::Index />`. This was working as expected in Discourse core, but we had not implemented the same in our custom resolver logic for themes/plugins.
This commit implements the `/index` fallback, and adds a test for the behaviour.
Our custom implementation of `getOwner` includes a fallback which returns an owner, even if the passed object does not have one set. This is confusing and creates a false sense of security. Generally if the fallback is used, it means there is a problem with the patterns being used.
This commit renames our custom implementation to `getOwnerWithFallback`, while maintaining the old `getOwner` export with a deprecation notice. Core code is updated to use the official `@ember/application` implementation, or the new `getOwnerWithFallback` function.
This commit updates all core uses of `{ getOwner } from discourse-common/lib/get-owner` to use `getOwnerWithFallback`. Future commits will work through and convert many of these to use the official `@ember/application` implementation
A new `rawRenderGlimmer` function is introduced which can be used to render glimmer components inside our legacy 'raw hbs' views. See discourse/lib/raw-render-glimmer for more information. This will help as we work to move away from raw-hbs use.
