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)
1. Sort plugins by name
2. Include plugins that are a symbolic link to a submodule repo (in those cases `.git` isn't a directory but a file that looks like e.g. `gitdir: ../../.git/modules/plugins/name-here`)
1. `test/run-qunit.js` wasn't eslinted (I'm not adding it to the CI workflow for now, just fixed the issues)
2. "…" utf character isn't rendered correctly in Jenkins, replaced with three dots
3. Don't try to lint `tmp` when doing `eslint .` in the root dir
Missing plugin gems are installed when the app is being loaded.
That means when you run `bin/rails plugin:install_all_gems` it first installs missing gems and then reinstalls all gems…
Also, the method these rake tasks were using to install gems was very crude, and the regex there was incorrect which resulted in failures in certain cases. Though that didn't matter since those gems were being installed using a correct method just moments before…
…to avoid repeatedly printed notes:

`Dir.glob` doesn't guarantee any particular order for results. However, it does appear to be consistent on a given machine. This means that specs can consistently pass on one machine while consistently failing on another. This can lead to some very confusing situations!
This commit sorts the spec files alphabetically so that load order is consistent across environments.
Note that the order in which tests are **run** is not affected by this change. Run order is still randomized by RSpec

This commit introduces a new environment variable `RAISE_THEME_ERRORS`
that can control what happens when `theme:update` Rake task errors. It
can have three possible values: `0` to always print errors, `1` to
always raise on error, or be absent to use the default behavior which
raises errors only for default sites.
Example error:
```
/__w/discourse/discourse/lib/tasks/assets.rake:3: warning: already initialized constant EMBER_CLI
/__w/discourse/discourse/lib/tasks/assets.rake:3: warning: previous definition of EMBER_CLI was here
```
The `assets:precompile` rake task loads the full Ruby app, which can consume around 500mb of RAM by itself. Using `exec` to run `ember build` allows us to free up the Ruby memory and make more space for `ember build`
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.
Ember CLI gives sourcemaps their own digest. Our `s3.rake` logic assumes that the digest portion of sourcemap filenames remains the same.
The Ember CLI sourcemaps are included in the manifest file, so we can ensure they are uploaded by letting them past the MiniMime check.

If no path is supplied, browsers will look for the map on the same path as the JS file itself. This fixes two problems that we see in production:
1. When compiling assets against one CDN, and then re-using them on a site with a different CDN, the sourceMappingUrls would be incorrect and print warnings in the console
2. If both an S3 CDN and an app CDN are configured, we were using the S3 CDN for the JS and the app CDN for the map. This commit will make sure we use the S3 CDN for both.
ember-cli already runs terser on its output. Running it through again provides no benefit, takes longer, and also breaks source mapping of these assets in production.
This can be disabled by setting `EMBER_CLI_PROD_ASSETS=0`, but this option will not be available for long. If your theme/plugin/site has issues under Ember CLI, please open a topic on https://meta.discourse.org
Job arguments go via JSON, and so symbols will appear as strings in the Job's `#execute` method. The latest version of Sidekiq has started warning about this to reduce developer confusion.
Running `update_from_remote` and `save!` cause a number of side-effects, including instructing all clients to reload CSS files. If there are no changes, then this is wasteful, and can even cause a 'flicker' effect on clients as they reload CSS.
This commit checks if any updates are available before triggering `update_from_remote` / `save!`. This should be much faster, and stop the 'flickering' UX from happening on every themes:update run.
It also improves the output of the command to include the from/to commit hashes, which may be useful for debugging issues. For example:
```
Checking 'Alien Night | A Dark Discourse Theme' for 'default'... already up to date
Checking 'Star Wars' for 'default'... updating from d8a170dd to 66b9756f
Checking 'Media Overlay' for 'default'... already up to date
```
`account_created` email contains a URL to `/u/password-reset/TOKEN`
which means that the correct scope for the email token is
`password_reset`, not `signup`.
For now this is still gated behind a `QUNIT_EMBER_CLI=1` environment variable, but will eventually become the default so that we can remove `run-qunit.js`.
This reverts commit 2c7906999a.
The changes break some things in local development (putting JS files
into minified files, not allowing debugger, and others)
This reverts commit ea84a82f77.
This is causing problems with `/theme-qunit` on legacy, non-ember-cli production sites. Reverting while we work on a fix
This is quite complex as it means that in production we have to build
Ember CLI test files and allow them to be used by our Rails application.
There is a fair bit of glue we can remove in the future once we move to
Ember CLI completely.
The `plugin:pull_compatible_all` task is intended to take incompatible plugins and downgrade them to an earlier version. Problem is, when running the rake task in development/production environments, the plugins have already been activated. If an incompatible plugin raises an error in `plugin.rb` then the rake task will be unable to start.
This commit centralises our LOAD_PLUGINS detection, adds support for LOAD_PLUGINS=0 in dev/prod, and adds a warning to `plugin:pull_compatible_all` if it's run with plugins enabled.
Also:
* Remove an unused method (#fill_email)
* Replace a method that was used just once (#generate_username) with `SecureRandom.alphanumeric`
* Remove an obsolete dev puma `tmp/restart` file logic
* File.exists? is deprecated and removed in Ruby 3.2 in favor of
File.exist?
* Dir.exists? is deprecated and removed in Ruby 3.2 in favor of
Dir.exist?
