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
rendering of the page. CSS should be loaded ASAP.
This change speeds up first contentful paint by 0.2s on localhost.
The slower the device, the bigger the difference could be.
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.
* precompile auto generated plugin js assets

* remove plugin js from test_helper

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.

There was some old code that restricted a percentage of a themes code from
admin, only when admin was refreshed, this leads to lots of confusion
Conditional is now removed
* Phase 0 for user-selectable theme components
- Drops `key` column from the `themes` table

- Removes the `default_theme_key` site setting and adds `default_theme_id` instead.
- Replaces `theme_key` cookie with a new one called `theme_ids`
- no longer need Theme.settings_for_client
