Previously, accessing the Rails app directly in development mode would give you assets from our 'legacy' Ember asset pipeline. The only way to run with Ember CLI assets was to run ember-cli as a proxy. This was quite limiting when working on things which are bypassed when using the ember-cli proxy (e.g. changes to `application.html.erb`). Also, since `ember-auto-import` introduced chunking, visiting `/theme-qunit` under Ember CLI was failing to include all necessary chunks.
This commit teaches Sprockets about our Ember CLI assets so that they can be used in development mode, and are automatically collected up under `/public/assets` during `assets:precompile`. As a bonus, this allows us to remove all the custom manifest modification from `assets:precompile`.
The key changes are:
- Introduce a shared `EmberCli.enabled?` helper
- When ember-cli is enabled, add ember-cli `/dist/assets` as the top-priority Rails asset directory
- Have ember-cli output a `chunks.json` manifest, and teach `preload_script` to read it and append the correct chunks to their associated `afterFile`
- Remove most custom ember-cli logic from the `assets:precompile` step. Instead, rely on Rails to take care of pulling the 'precompiled' assets into the `public/assets` directory. Move the 'renaming' logic to runtime, so it can be used in development mode as well.
- Remove fingerprinting from `ember-cli-build`, and allow Rails to take care of things
Long-term, we may want to replace Sprockets with the lighter-weight Propshaft. The changes made in this commit have been made with that long-term goal in mind.
tldr: when you visit the rails app directly, you'll now be served the current ember-cli assets. To keep these up-to-date make sure either `ember serve`, or `ember build --watch` is running. If you really want to load the old non-ember-cli assets, then you should start the server with `EMBER_CLI_PROD_ASSETS=0`. (the legacy asset pipeline will be removed very soon)
These were originally very similar, but have diverged over time. This makes it very difficult to manage styling.
This commit moves the noscript header and footer into partials so they can be reused in both the crawler view and the `<noscript>` view. It also makes browser-update render the noscript content **instead of** the `<section id='main'>`, rather than adding adding the noscript inside the `<section>`. This provides better parity with the server-rendered crawler view.
This makes a small improvement to 'cold cache' ember-cli build times, and a large improvement to 'warm cache' build times
The ember-auto-import update means that vendor is now split into multiple files for efficiency. These are named `chunk.*`, and should be included immediately after the `vendor.js` file. This commit also updates the rails app to render script tags for these chunks.
This change was previously merged, and caused memory-related errors on RAM-constrained machines. This was because Webpack 5 switches from multiple worker processes to a single multi-threaded process. This meant that it was hitting node's default heap size limit (~500mb on a 1GB RAM server). Discourse's standard install procedure recommends adding 2GB swap to 1GB-RAM machines, so we can afford to override's Node's default via the `--max-old-space-size` flag.
This reverts commit f4c6a61855 and a8325c9016
This update of ember-auto-import and webpack causes significantly higher memory use during rebuilds. This made ember-cli totally unusable on 1GB RAM / 2GB swap environments. We don't have a specific need for this upgrade right now, so reverting for now.

Under some conditions, these varied responses could lead to cache poisoning, hence the 'security' label.
Previously the Rails application would serve JSON data in place of HTML whenever Ember CLI requested an `application.html.erb`-rendered page. This commit removes that logic, and instead parses the HTML out of the standard response. This means that Rails doesn't need to customize its response for Ember CLI.
We have two JS assets which are included in the `<body>` of responses. We were including the `<link rel='preload'` hint alongside the script tag in the body. Instead, we can move the preload hint to the `<head>` so that the browser discovers it earlier, and can start preloading the assets while the body is loading.
This was problematic if something like SCSS file throws an error as the
app would tell Ember CLI to bootstrap as if everything is fine and not
display the error.
The fix is to only hijack the rendering at the end of the template
instead of the beginning.
This adds an optional ENV variable, `EMBER_CLI_PROD_ASSETS`. If truthy,
compiling production assets will be done via Ember CLI and will replace
the assets Rails would otherwise use.
Before this change, calling `StyleSheet::Manager.stylesheet_details`
for the first time resulted in multiple queries to the database. This is
because the code was modelled in a way where each `Theme` was loaded
from the database one at a time.
This PR restructures the code such that it allows us to load all the
theme records in a single query. It also allows us to eager load the
required associations upfront. In order to achieve this, I removed the
support of loading multiple themes per request. It was initially added
to support user selectable theme components but the feature was never
completed and abandoned because it wasn't a feature that we thought was
worth building.
In Ember CLI addons get put into the vendor bundle, as opposed to their
own bundle like we're doing in the Rails app. We never use pretty-text
without our vendor bundle so this should have no difference on
performance.
We need to keep the pretty-text bundle for server side cooking.
In Ember CLI, the vendor bundler includes Ember/jQuery, so this brings
our app closer to that configuration.
We have a couple pages (Reset Password / Confirm New Email) where we need
`ember_jquery` without vendor so the file still exists for those cases.
* DEV: Give a nicer error when `--proxy` argument is missing
* DEV: Improve Ember CLI's bootstrap logic
Instead of having Ember CLI know which URLs to proxy or not, have it try
the URL with a special header `HTTP_X_DISCOURSE_EMBER_CLI`. If present,
and Discourse thinks we should bootstrap the application, it will
instead stop rendering and return a HTTP HEAD with a response header
telling Ember CLI to bootstrap.
In other words, any time Rails would otherwise serve up the HTML for the
Ember app, it stops and says "no, you do it."
* DEV: Support asset filters by path using a new options object
Without this, Ember CLI's bootstrap would not get the assets it wants
because the path it was requesting was different than the browser path.
This adds an optional request header to fix it.
So far this is only used by the styleguide.
This cookie is only used during login. Having it persist after that can
cause some unusual behavior, especially for sites with short session
lengths.
We were already deleting the cookie following a new signup, but not for
existing users.
This commit moves the cookie deletion logic out of the erb template, and
adds logic and tests to ensure it is always deleted consistently.

CSS are blocking resources, so keeping them below JS delays

DEV: Replace instances of Discourse.base_uri with Discourse.base_path
This is clearer because the base_uri is actually just a path prefix. This continues the work started in 555f467.
* DEV: To be pedantic, there is more than EMBER in there now
* DEV: Use less globals. Have `Discourse` start in an initializer
* DEV: Remove another global
In order to avoid a boatload of attributeBindings, I moved the root
element of the suggested-topics component into the template. Also,
autoformat their hbs files.
Testing info: https://www.scottohara.me/blog/2018/03/03/landmarks.html#using-screen-readers-to-navigate-landmarks
Additionally, flag modals with aria-modal=true to avoid the screenreader
accidentally escaping the modal. There's no need to ever toggle the
attribute to false, because we display:none the modal root when it's
closed.
Additionally correctly handle cookie path for authentication_data
There were two bugs that exposed an interesting case where two discourse
instances hosted across two subfolder installs in the same domain
with oauth may clash and cause strange redirection on first login:
Log in to example.com/forum1. authentication_data cookie is set with path /
On the first redirection, the current authentication_data cookie is not unset.
Log in to example.com/forum2. In this case, the authentication_data cookie
is already set from forum1 - the initial page load will incorrectly redirect
the user to the redirect URL from the already-stored cookie, to /forum1.
This removes this issue by:
* Setting the cookie for the correct path, and not having it on root
* Correctly removing the cookie on first login
Attempt 2, with more test.

When showing the native app banner, we include an app argument to automatically add the current site to the official DiscourseHub app. However, the app id can be changed via a hidden site setting, and when changed, that argument is no longer useful. This ensures the argument is only included for the official iOS app banner.
And don't load javascript assets if plugin is disabled.

You can now add javascript files under `/javascripts/*` in a theme, and they will be loaded as if they were included in core, or a plugin. If you give something the same name as a core/plugin file, it will be overridden. Support file extensions are `.js.es6`, `.hbs` and `.raw.hbs`.
This commit adds some improvements to native app banners for iOS and Android
- iOS and Android now have separate settings for native app banners
- app banners will now only show for users on TL1 and up
- app ids are now in a hidden site setting to allow sites to switch to their own app, if desired
- iOS only: the site URL is passed to the app arguments
This will allow users installing a Discourse PWA to use their active
theme colors on the generated app. Thanks for @mgiuca for the tip.
Also makes the share_target config explicit to silence Chrome warnings
- Themes can supply translation files in a format like `/locales/{locale}.yml`. These files should be valid YAML, with a single top level key equal to the locale being defined. For now these can only be defined using the `discourse_theme` CLI, importing a `.tar.gz`, or from a GIT repository.
- Fallback is handled on a global level (if the locale is not defined in the theme), as well as on individual keys (if some keys are missing from the selected interface language).
- Administrators can override individual keys on a per-theme basis in the /admin/customize/themes user interface.
- Theme developers should access defined translations using the new theme prefix variables:
JavaScript: `I18n.t(themePrefix("my_translation_key"))`
Handlebars: `{{theme-i18n "my_translation_key"}}` or `{{i18n (theme-prefix "my_translation_key")}}`
- To design for backwards compatibility, theme developers can check for the presence of the `themePrefix` variable in JavaScript
- As part of this, the old `{{themeSetting.setting_name}}` syntax is deprecated in favour of `{{theme-setting "setting_name"}}`
Regression following the ember3 upgrade. In addition to fixing, this commit consolidates our social registration logic into one place, and adds tests for the behaviour.
