DEV: Minimal first pass of rails system test setup (#16311) This commit introduces rails system tests run with chromedriver, selenium, and headless chrome to our testing toolbox. We use the `webdrivers` gem and `selenium-webdriver` which is what the latest Rails uses so the tests run locally and in CI out of the box. You can use `SELENIUM_VERBOSE_DRIVER_LOGS=1` to show extra verbose logs of what selenium is doing to communicate with the system tests. By default JS logs are verbose so errors from JS are shown when running system tests, you can disable this with `SELENIUM_DISABLE_VERBOSE_JS_LOGS=1` You can use `SELENIUM_HEADLESS=0` to run the system tests inside a chrome browser instead of headless, which can be useful to debug things and see what the spec sees. See note above about `bin/ember-cli` to avoid surprises. I have modified `bin/turbo_rspec` to exclude `spec/system` by default, support for parallel system specs is a little shaky right now and we don't want them slowing down the turbo by default either. ### PageObjects and System Tests To make querying and inspecting parts of the page easier and more reusable inbetween system tests, we are using the concept of [PageObjects](https://www.selenium.dev/documentation/test_practices/encouraged/page_object_models/) in our system tests. A "Page" here is generally corresponds to an overarching ember route, e.g. "Topic" for `/t/324345/some-topic`, and this contains logic for querying components within the topic such as "Posts". I have also split "Modals" into their own entity. Further down the line we may want to explore creating independent "Component" contexts. Capybara DSL should be included in each PageObject class, reference for this can be found at https://rubydoc.info/github/teamcapybara/capybara/master#the-dsl For system tests, since they are so slow, we want to focus on the "happy path" and not do every different possible context and branch check using them. They are meant to be overarching tests that check a number of things are correct using the full stack from JS and ember to rails to ruby and then the database. ### CI Setup Whenever a system spec fails, a screenshot is taken and a build artifact is produced _after the entire CI run is complete_, which can be downloaded from the Actions UI in the repo. Most importantly, a step to build the Ember app using Ember CLI is needed, otherwise the JS assets cannot be found by capybara: ``` - name: Build Ember CLI run: bin/ember-cli --build ``` A new `--build` argument has been added to `bin/ember-cli` for this case, which is not needed locally if you already have the discourse rails server running via `bin/ember-cli -u` since the whole server is built and set up by default.

FEATURE: Generic hashtag autocomplete lookup and markdown cooking (#18937) This commit fleshes out and adds functionality for the new `#hashtag` search and lookup system, still hidden behind the `enable_experimental_hashtag_autocomplete` feature flag. **Serverside** We have two plugin API registration methods that are used to define data sources (`register_hashtag_data_source`) and hashtag result type priorities depending on the context (`register_hashtag_type_in_context`). Reading the comments in plugin.rb should make it clear what these are doing. Reading the `HashtagAutocompleteService` in full will likely help a lot as well. Each data source is responsible for providing its own **lookup** and **search** method that returns hashtag results based on the arguments provided. For example, the category hashtag data source has to take into account parent categories and how they relate, and each data source has to define their own icon to use for the hashtag, and so on. The `Site` serializer has two new attributes that source data from `HashtagAutocompleteService`. There is `hashtag_icons` that is just a simple array of all the different icons that can be used for allowlisting in our markdown pipeline, and there is `hashtag_context_configurations` that is used to store the type priority orders for each registered context. When sending emails, we cannot render the SVG icons for hashtags, so we need to change the HTML hashtags to the normal `#hashtag` text. **Markdown** The `hashtag-autocomplete.js` file is where I have added the new `hashtag-autocomplete` markdown rule, and like all of our rules this is used to cook the raw text on both the clientside and on the serverside using MiniRacer. Only on the server side do we actually reach out to the database with the `hashtagLookup` function, on the clientside we just render a plainer version of the hashtag HTML. Only in the composer preview do we do further lookups based on this. This rule is the first one (that I can find) that uses the `currentUser` based on a passed in `user_id` for guardian checks in markdown rendering code. This is the `last_editor_id` for both the post and chat message. In some cases we need to cook without a user present, so the `Discourse.system_user` is used in this case. **Chat Channels** This also contains the changes required for chat so that chat channels can be used as a data source for hashtag searches and lookups. This data source will only be used when `enable_experimental_hashtag_autocomplete` is `true`, so we don't have to worry about channel results suddenly turning up. ------ **Known Rough Edges** - Onebox excerpts will not render the icon svg/use tags, I plan to address that in a follow up PR - Selecting a hashtag + pressing the Quote button will result in weird behaviour, I plan to address that in a follow up PR - Mixed hashtag contexts for hashtags without a type suffix will not work correctly, e.g. #ux which is both a category and a channel slug will resolve to a category when used inside a post or within a [chat] transcript in that post. Users can get around this manually by adding the correct suffix, for example ::channel. We may get to this at some point in future - Icons will not show for the hashtags in emails since SVG support is so terrible in email (this is not likely to be resolved, but still noting for posterity) - Additional refinements and review fixes wil
