Modern Ember only sets up a container when the ApplicationInstance is booted. We have legacy code which relies on having access to a container before boot (e.g. during pre-initializers).
In production we run with the default `autoboot` flag, which triggers Ember's internal `_globalsMode` flag, which sets up an ApplicationInstance immediately when an Application is initialized (via the `_buildDeprecatedInstance` method).
In tests, we worked around the problem by creating a fresh container, and placing a reference to it under `Discourse.__container__`.
HOWEVER, Ember was still creating a Container instance for each ApplicationInstance to use internally, and make available to EmberObjects via injection. The `Discourse.__container__` instance we created was barely used at all.
Having two different Container instances in play could cause some weird issues. For example, I noticed the problem because the `appEvents` instance held by DiscourseURL was different to the `appEvents` instance held by all the Ember components in our app. This meant that events triggered by DiscourseURL were not picked up by components in test mode.
This commit makes the hack more robust by ensuring that Ember re-uses the Container instance which we created pre-boot. This means we only have one Container instance in play, and makes `appEvents` work reliably across all parts of the app. It also adds detailed comments describing the hack, to help future travelers.
Hopefully in future we can remove this hack entirely, but it will require significant refactoring to our initialization process in Core and Plugins.
The mapping-router and map-routes initializer are updated to avoid the need for `container.lookup` during teardown. This isn't allowed under modern Ember, but was previously working for us because the pre-initializer was using the 'fake' container which was not ember-managed.
da6edc1 introduced the `lookupView` method, which initialized a fresh resolver, and used it to directly look up raw-views (with no caching). This worked well, but was not a clean solution. It required initializing an entirely new resolver, and did not have any caching.
This commit updates the `helperContext` to include access to the registry, and uses it to perform raw-view lookups. As well as re-using the registry, this also means we're making use of the resolver's built-in cache.
I haven't been able to measure any noticeable performance impact from this change, but there is certainly less work being done, so it may be beneficial on older devices.

Also removes "appEventsCache". (and reduces the reported test memory usage by ~33%)
There's no longer any need to remove appEvent listeners in application-instance initializers' `teardown`, as app instances are recreated before each test (in both legacy and ember cli envs)
- Allow the `/presence/get` endpoint to return multiple channels in a single request (limited to 50)
- When multiple presence channels are initialized in a single Ember runloop, batch them into a single GET request
- Introduce the `presence-pretender` to allow easy testing of PresenceChannel-related features
- Introduce a `use_cache` boolean (default true) on the the server-side PresenceChannel initializer. Useful during testing.
Previously we would store every FakeRequest object for all tests, resulting in many hundreds/thousands of objects in the `handledRequests` array.
This commit ensures all pretender state is reset between tests.
This is `console.log`'d to the browser console. run-qunit will print this to stdout. testem will not, so a custom reporter is implemented to print this message.
The `--enable-precise-memory-info` is added so that chrome provides high-resolution memory information. This API is not supported by firefox. The logic will degrade gracefully.
We were using multiple methods to check which environment we're running in. This commit switches us to use the isLegacyEmber helper consistently. This should be a no-op, but makes the code much easier to read
Under Ember CLI, we create a new application instance for each test. We were not correctly destroying it after the test, causing many references to be maintaned (e.g. at the end of a test run, `Ember.Namespace.NAMESPACES` would have an entry for each application instance).
Calling `destroy` on the application instance tidies up these references, and is one step towards fixing our test memory leak problem. Unfortunately there still seem to be other references being held to the application, so this commit is not a total fix.
This commit also hides a number of options which are not used during Discourse development.
Change have been tested on both the legacy `/qunit` route, and the Ember CLI `/tests` route.
This adds support for `qunit_skip_core`, `qunit_skip_plugins` and `qunit_single_plugin` parameters on the Ember CLI `/tests` route using the `addModuleExcludeMatcher` API. Legacy support is maintained for the `/qunit` route.
The first thing we needed here was an enum rather than a boolean to determine how a directory_column was created. Now we have `automatic`, `user_field` and `plugin` directory columns.
This plugin API is assuming that the plugin has added a migration to a column to the `directory_items` table.
This was created to be initially used by discourse-solved. PR with API usage - https://github.com/discourse/discourse-solved/pull/137/
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change

This commit allows site admins to run theme tests in production via a new `/theme-qunit` route. When you visit `/theme-qunit`, you'll see a list of the themes/components installed on your site that have tests, and from there you can select a theme or component that you run its tests.
We also have a new rake task `themes:install_and_test` that can be used to install a list of themes/components on a temporary database and run the tests of the themes/components that are installed. This rake task can be useful when upgrading/deploying a Discourse instance to make sure that the installed themes/components are compatible with the new Discourse version being deployed, and if the tests fail you can abort the build/deploy process so you don't end up with a broken site.

This commit allows themes and theme components to have QUnit tests. To add tests to your theme/component, create a top-level directory in your theme and name it `test`, and Discourse will save all the files in that directory (and its sub-directories) as "tests files" in the database. While tests files/directories are not required to be organized in a specific way, we recommend that you follow Discourse core's tests [structure](https://github.com/discourse/discourse/tree/master/app/assets/javascripts/discourse/tests).
Writing theme tests should be identical to writing plugins or core tests; all the `import` statements and APIs that you see in core (or plugins) to define/setup tests should just work in themes.
You do need a working Discourse install to run theme tests, and you have 2 ways to run theme tests:
* In the browser at the `/qunit` route. `/qunit` will run tests of all active themes/components as well as core and plugins. The `/qunit` now accepts a `theme_name` or `theme_url` params that you can use to run tests of a specific theme/component like so: `/qunit?theme_name=<your_theme_name>`.
* In the command line using the `themes:qunit` rake task. This take is meant to run tests of a single theme/component so you need to provide it with a theme name or URL like so: `bundle exec rake themes:qunit[name=<theme_name>]` or `bundle exec rake themes:qunit[url=<theme_url>]`.
There are some refactors to how Discourse processes JavaScript that comes with themes/components, and these refactors may break your JS customizations; see https://meta.discourse.org/t/upcoming-core-changes-that-may-break-some-themes-components-april-12/186252?u=osama for details on how you can check if your themes/components are affected and what you need to do to fix them.
This commit also improves theme error handling in Discourse. We will now be able to catch errors that occur when theme initializers are run and prevent them from breaking the site and other themes/components.

There are some refactors to internal code that's responsible for processing themes/components in Discourse, most notably:
* `<script type="text/discourse-plugin">` tags are automatically converted to modules.
* The `theme-settings` service is removed in favor of a simple `lib` file responsible for managing theme settings. This was done to allow us to register/lookup theme settings very early in our Ember app lifecycle and because there was no reason for it to be an Ember service.
These refactors should 100% backward compatible and invisible to theme developers.
By default our QUnit test runner starts automatically. This is normally
fine but for our `run-qunit.js` script we add a bunch of QUnit events
using `eval` and sometimes those events were added after the tests
already started/finished resulting in a hang.
This adds a new parameter that will cause QUnit not to run
automatically, which the runner uses, then triggers a `start()` when it
knows it's ready.
This encompasses a lot of work done over the last year, much of which
has already been merged into master. This is the final set of changes
required to get Ember CLI running locally for development.
From here on it will be bug fixes / enhancements.

* The creation of a testing div is specific to Rails, so that is
moved back out of setupTests();
* We've removed the `Discourse` globals from the acceptance helpers in favor of
`setApplication`/`getApplication`.
* We pass the container to setupTests because there is no
`__container__` in later Ember versions.
* `App` is now `app` because it's not a constant or class, it's an
instance of an application.
I also took the opportunity with this commit to move some test specific
stuff out of `discourse-loader` which is loaded on the front end of the
application. The test module building now happens in the `test_helper`
bundle.
This is long overdue. We had a lot of (not linted) code to initialize
our test suite as part of the Ruby `test_helper.js` bundle.
This refactor moves that out to a `setup-tests` module, which imports
all the modules properly, rather than using `require`.
It also removes the global `server` variable which some tests were using
for pretender. Those tests are fixed, and in the case of widget tests,
support for a `pretend()` was added, which mimics our acceptance tests.
One problematic test was removed, which overwrites `/posts` - this could
break tons of other tests depending on order.
