This commit introduces the scaffolding for us to easily switch between Ember 3.28 and Ember 5 on the `main` branch of Discourse. Unfortunately, there is no built-in system to apply this kind of flagging within yarn / ember-cli. There are projects like `ember-try` which are designed for running against multiple version of a dependency, but they do not allow us to 'lock' dependency/sub-dependency versions, and are therefore unsuitable for our use in production.
Instead, we will be maintaining two root `package.json` files, and two `yarn.lock` files. For ember-3, they remain as-is. For ember5, we use a yarn 'resolution' to override the version for ember-source across the entire yarn workspace.
To allow for easy switching with minimal diff against the repository, `package.json` and `yarn.lock` are symlinks which point to `package-ember3.json` and `yarn-ember3.lock` by default. To switch to Ember 5, we can run `script/switch ember version 5` to update the symlinks to point to `package-ember5.json` and `package-ember3.json` respectively. In production, and when using `bin/ember-cli` for development, the ember version can also be upgraded using the `EMBER_VERSION=5` environment variable.
When making changes to dependencies, these should be made against the default `ember3` versions, and then `script/regen_ember_5_lockfile` should be used to regenerate `yarn-ember5.lock` accordingly. A new 'Ember Version Lockfiles' GitHub workflow will automate this process on Dependabot PRs.
When running a local environment against Ember 5, the two symlink changes will show up as git diffs. To avoid us accidentally committing/pushing that change, another GitHub workflow is introduced which checks the default Ember version and raises an error if it is greater than v3.
Supporting two ember versions simultaneously obviously carries significant overhead, so our aim will be to get themes/plugins updated as quickly as possible, and then drop this flag.
This breaks the `plugin:install_all_gems` Rake task when used before
Redis is running. Need to go back to the drawing board.
This reverts commit 189aa5fa4e.
Why this change?
This regressed in dec68d780c where the
commit assumes that plugin gems are always installed when the
`plugin:install_all_gems` Rake task is ran as it would run the our Rails
initializers which activates plugins and install the gems. However, this
assumption only holds true when the `LOAD_PLUGINS` is present and set to
`1`.
What does this change do?
This commit changes the `plugin:install_all_gems` to load the Rails
environment with `LOAD_PLUGINS` set to `1` such that the plugin gems
will be installed as part of our initialization process for the app.
The commit also removes the `plugin:install_gems` Rake task which is
currently a noop and does not seem to be used anywhere..
Why this change?
Similar to d0117ff6e3, `plugins:update_all` spends most of its time waiting
on the network. On my local machine, this takes up to 2 mins when I have
all the official plugins installed. On a 32 cores machine, the total
time is cut down to 4 seconds.
What does this change do?
1. Move the logic in the `plugin:update` Rake task into a method.
2. Updates the `plugin:update` and `plugin:update_all` to rely on the
new method.
3. Wraps the method call to update a plugin in `plugin:update_all` in a
`Concurrent::Promise`
This change also adds the `--quiet` option to the `git pull` option
since the `git pull` output is just noise for 99% of the time.
Why this change?
`plugin:install_all_official` is quite slow at the moment taking roughly
1 minute and 51 seconds on my machine. Since most of the time is spent
waiting on the network, we can actually speed up the Rake task
significantly by executing the cloning concurrently. With a 8 cores
machine, cloning all plugins will only take 15 seconds.
What does this change do?
This change wraps the `git clone` operation in the
`plugin:install_all_official` Rake task in a `Concurrent::Promise` which
basically runs the `git clone` operation in a Thread. The `--quiet`
option has also been added to `git clone` since running stuff
concurrently messes up the output. That could be fixed but it has been
determined to be not worth it since the output from `git clone` is
meaningless to us.
Why this change?
There are instances where we would like to customize what the
`docker:test:setup` Rake task does.
What does this change do?
Adds a bunch of env variables that could be set to customize what the
`docker:test:setup` Rake test does.
Why this change?
We support a `USE_TURBO` environment variable which tells the
`docker:test` rake task to run rspec tests in parallel. However, this
currently does not apply to system tests.
What does this change do?
This commit runs system specs for both core and plugins using
`./bin/turbo_rspec` when the `USE_TURBO` environment is present. Note
that when running system specs, we will only spawn X number of test
processes where X is half the number of available CPU cores. This is
done because we have to leave CPU resources for the chrome processes
that will be created.
Why this change?
As the number of themes which the Discourse team supports officially
grows, we want to ensure that changes made to Discourse core do not
break the plugins. As such, we are adding a step to our Github actions
test job to run the QUnit tests for all official themes.
What does this change do?
This change adds a new job to our tests Github actions workflow to run the QUnit
tests for all official plugins. This is achieved with the following
changes:
1. Update `testem.js` to rely on the `THEME_TEST_PAGES` env variable to set the
`test_page` option when running theme QUnit tests with testem. The
`test_page` option [allows an array to be specified](https://github.com/testem/testem#multiple-test-pages) such that tests for
multiple pages can be run at the same time. We are relying on a ENV variable
because the `testem` CLI does not support passing a list of pages
to the `--test_page` option.
2. Support a `/testem-theme-qunit/:testem_id/theme-qunit` Rails route in the development environment. This
is done because testem prefixes the path with a unique ID to the configured `test_page` URL.
This is problematic for us because we proxy all testem requests to the
Rails server and testem's proxy configuration option does not allow us
to easily rewrite the URL to remove the prefix. Therefore, we configure a proxy in testem to prefix `theme-qunit` requests with
`/testem-theme-qunit` which can then be easily identified by the Rails server and routed accordingly.
3. Update `qunit:test` to support a `THEME_IDS` environment variable
which will allow it to run QUnit tests for multiple themes at the
same time.
4. Support `bin/rake themes:qunit[ids,"<theme_id>|<theme_id>"]` to run
the QUnit tests for multiple themes at the same time.
5. Adds a `themes:qunit_all_official` Rake task which runs the QUnit
tests for all the official themes.
Why this change?
By default the `db:create` Rake task in activerecord creates the
databases for both the development and test environment. This while
seemingly odd is by design from Rails. In order to avoid creating the
test database, Rails supports the `SKIP_TEST_DATABASE` environment
variable which we should respect when creating the multisite test
database.
Why this change?
As the number of themes which the Discourse team supports officially
grows, we want to ensure that changes made to Discourse core do not
break the plugins. As such, we are adding a step to our Github actions
test job to run the system tests for all official themes.
What does this change do?
This change adds a step to our Github actions test job to run the system
tests for all official plugins. This is achieved by the introduction of
the `themes:install_all_official` Rake task which installs all the
themes that are officially supported by the Discourse team.
- Remove vendored copy
- Update Rails implementation to look for language definitions in node_modules
- Use webpack-based dynamic import for hljs core
- Use browser-native dynamic import for site-specific language bundle (and fallback to webpack-based dynamic import in tests)
- Simplify markdown implementation to allow all languages into the `lang-{blah}` className
- Now that all languages are passed through, resolve aliases at runtime to avoid the need for the pre-built `highlightjs-aliases` index
This commit introduces a new feature that allows theme developers to manage the transformation of theme settings over time. Similar to Rails migrations, the theme settings migration system enables developers to write and execute migrations for theme settings, ensuring a smooth transition when changes are required in the format or structure of setting values.
Example use cases for the theme settings migration system:
1. Renaming a theme setting.
2. Changing the data type of a theme setting (e.g., transforming a string setting containing comma-separated values into a proper list setting).
3. Altering the format of data stored in a theme setting.
All of these use cases and more are now possible while preserving theme setting values for sites that have already modified their theme settings.
Usage:
1. Create a top-level directory called `migrations` in your theme/component, and then within the `migrations` directory create another directory called `settings`.
2. Inside the `migrations/settings` directory, create a JavaScript file using the format `XXXX-some-name.js`, where `XXXX` is a unique 4-digit number, and `some-name` is a descriptor of your choice that describes the migration.
3. Within the JavaScript file, define and export (as the default) a function called `migrate`. This function will receive a `Map` object and must also return a `Map` object (it's acceptable to return the same `Map` object that the function received).
4. The `Map` object received by the `migrate` function will include settings that have been overridden or changed by site administrators. Settings that have never been changed from the default will not be included.
5. The keys and values contained in the `Map` object that the `migrate` function returns will replace all the currently changed settings of the theme.
6. Migrations are executed in numerical order based on the XXXX segment in the migration filenames. For instance, `0001-some-migration.js` will be executed before `0002-another-migration.js`.
Here's a complete example migration script that renames a setting from `setting_with_old_name` to `setting_with_new_name`:
```js
// File name: 0001-rename-setting.js
export default function migrate(settings) {
if (settings.has("setting_with_old_name")) {
settings.set("setting_with_new_name", settings.get("setting_with_old_name"));
}
return settings;
}
```
Internal topic: t/109980
Followup to b53449eac9, we cannot
generate the links to plugin admin pages in this way because it
depends on which plugins are installed; we would need to somehow
do it at runtime. Leaving it out for now, for people who need to
find these admin routes the Ember Inspector extension for Chrome
can be used in the meantime.
NOTE: Most of this is experimental and will be removed at a later
time, which is why things like translations have not been added.
The new /admin-revamp UI uses a sidebar for admin nav. This initial
step adds a script to generate a map of all the current admin nav
into a format the sidebar to read. Then, people can experiment
with different changes to this structure.
The structure can then be edited from `/admin-revamp/config/sidebar-experiment`,
and it is saved to local storage so people can visually experiment with different ways
of showing the admin sidebar links.
- Remove the wildcard crawler. This was already excluding almost all file types, but the exclude list was missing '.gjs' which meant those files were unnecessarily being hoisted into the `public/` directory during precompile
- Automatically include all ember-cli-generated assets without needing them to be listed. The main motivation for this change is to allow us to start using async imports via Embroider/Webpack. The filenames for those new async bundles will not be known in advance.
- Skips sprockets fingerprinting on Embroider/Webpack chunk JS files. Their filenames already include a fingerprint, and having sprockets change the filenames will cause problems for the async import feature (where filenames are included deep inside js bundles)
This commit also updates our ember-cli build so that it skips building plugin tests in the production environment. This should provide a slight build speed improvement.
No plugins or themes rely on anonymous_posting_min_trust_level so we
can just switch straight over to anonymous_posting_allowed_groups
This also adds an AUTO_GROUPS const which can be imported in JS
tests which is analogous to the one defined in group.rb. This can be used
to set the current user's groups where JS tests call for checking these groups
against site settings.
Finally a AtLeastOneGroupValidator validator is added for group_list site
settings which ensures that at least one group is always selected, since if
you want to allow all users to use a feature in this way you can just use
the everyone group.
* DEV: refactor rake asset precompile tasks
add a separate ember build task that does not depend on rails env
allowing us to compile assets without db+redis connections
rename EMBER_CLI_COMPILE_DONE to SKIP_EMBER_CLI_COMPILE
better semantics in build steps
We will soon be dropping support for `/theme-qunit` in production, so this will start failing if we don't remove it. Plus, we now have system specs which verify the end-to-end functionality of the Theme QUnit system.
This was the last thing which was using the legacy `run-qunit` script, so that can also be dropped.
Until now, we have allowed testing themes in production environments via `/theme-qunit`. This was made possible by hacking the ember-cli build so that it would create the `tests.js` bundle in production. However, this is fundamentally problematic because a number of test-specific things are still optimized out of the Ember build in production mode. It also makes asset compilation significantly slower, and makes it more difficult for us to update our build pipeline (e.g. to introduce Embroider).
This commit removes the ability to run qunit tests in production builds of the JS app when the Embdroider flag is enabled. If a production instance of Discourse exists exclusively for the development of themes (e.g. discourse.theme-creator.io) then they can add `EMBER_ENV: development` to their `app.yml` file. This will build the entire app in development mode, and has a significant performance impact. This must not be used for real production sites.
This commit also refactors many of the request specs into system specs. This means that the tests are guaranteed to have Ember assets built, and is also a better end-to-end test than simply checking for the presence of certain `<script>` tags in the HTML.
This is a follow up to 9caba30d5c
In that commit, we were migrating the database but we didn't actually
ensure that the database was created and that plugins were updated
before the databases were migrated.
## What is the context here?
The `docker.rake` Rakefile contains Rake tasks that are meant to be run
in the `discourse/discourse_test:release` Docker image. For example, we
have the `docker:test` Rake task that makes it easier to run the test
suite for a particular Discourse commit.
Why are we introducing a `docker:test:setup` Rake task?
While we have the `docker:test` Rake task, it is very limited in the
test commands that can be executed. It is very useful for automated
testing but not very useful for running tests in the development
environment. Therefore, we are introducing a `docker:test:setup` rake
task that can be used to set up the test environment for running tests.
The envisioned example usage is something like this:
```
docker run -d --name=discourse_test --entrypoint=/sbin/boot discourse/discourse_test:release
docker exec -u discourse:discourse discourse_test ruby script/docker_test.rb --no-tests
docker exec -u discourse:discourse discourse_test bundle exec rake docker:test:setup
docker exec -u discourse:discourse discourse_test bundle exec rspec <path to file>
```
This adds a new secure_uploads_pm_only site setting. When secure_uploads
is true with this setting, only uploads created in PMs will be marked
secure; no uploads in secure categories will be marked as secure, and
the login_required site setting has no bearing on upload security
either.
This is meant to be a stopgap solution to prevent secure uploads
in a single place (private messages) for sensitive admin data exports.
Ideally we would want a more comprehensive way of saying that certain
upload types get secured which is a hybrid/mixed mode secure uploads,
but for now this will do the trick.
The theme tests we use for the smoke-test typically take 3-4 seconds to complete. This commit reduces the timeout from 10 minutes to 20 seconds, so that failures are detected more quickl
* DEV: Add rake command to help detect dead settings
Some Site Settings may still exist but are no longer being used in the
core discourse code or in related plugins. This rake task will help
identify any unused (aka: dead) settings by using the `rg` command to
search for them.
You can execute the rake task by using this command:
`LOAD_PLUGINS=1 bin/rails "site_settings:find_dead"`
* Add env variable, apply feedback
