Fixes a bug in user preferences > interface, the light scheme dropdown
was defaulting to "Theme Default" even when the user had selected a
different scheme.
In Discourse, `rails s` ultimately launches the `bin/unicorn` script. However, the overhead of `rails` launching `bin/rails`, and then in turn `bin/unicorn` can be non-trivial. Therefore it is much better to run `bin/unicorn` directly.
This commit prints a warning message to STDERR when `rails s` is used. Functionality is unchanged.
This commit makes a few changes to improve boot time in development environments. It will have no effect on production boot times.
- Skip the SchemaCache warmup. In development mode, the SchemaCache is refreshed every time there is a code change, so warmup is of limited use.
- Skip warming up PrettyText. This adds ~2s to each web worker's boot time. The vast majority of requests do not use PrettyText, so it is more efficient to defer its warmup until it's needed
- Skip the intentional 1 second pause during Unicorn worker forking. The comment (which also exists in Unicorn's documentation) suggests this works around a Unix signal handling bug, but I haven't been able to locate any more information. Skipping it in dev will significantly speed up boot. If we start to see issues, we can revert this change.
On my machine, this improves `/bin/unicorn` boot time from >10s to ~4s
This updates the preview_theme_id preservation logic to use more recent, robust, browser APIs. It also adds support for preserving the `?pp=async-flamegraph` parameter which is proposed in https://github.com/MiniProfiler/rack-mini-profiler/pull/494
Sometimes, parts of the application pass in the locale as a string, not a symbol. This was causing the translate_accelerator to cache two versions of the locale separately: one cache for the symbol version, and one cache for the string version. For example, in a running production process:
```
irb(main):001:0> I18n.instance_variable_get(:@loaded_locales)
=> [:en, "en"]
```
This commit ensures the `locale` key is always converted to a symbol, and adds a spec to ensure the same locale cannot appear twice in `@loaded_locales`
In development we regularly restart/reload Rails, which wipes out the schema cache. This then has to be regenerated using DDL queries on the database.
Instead, we can make use of the `rake db:schema:cache:dump` command. This will dump the schema cache to a YAML file, and then load it when needed. This is significantly faster than rebuilding the cache from DDL queries every time.
If the associated page of a remote url passed to `TopicEmber.new(remote_url)` contained a malformed link like: `<a href="(http://foo.bar)">Baz</a>` it would raise an uncaught exception:
```
Job exception: Invalid scheme format: (http
```
We really want to encourage all developers to use Ember CLI for local
development and testing. This will display an error page if they are not
with instructions on how to start the local server.
To disable it, you can set `NO_EMBER_CLI=1` as an ENV variable
* FEATURE: Small improvements to the topic list embed
- Ability to wrap the list in a custom class so you can styles different
lists using specific CSS
- Adds a topic link to the thumbnail when using the complete template
* FIX: Be more strict about allowed chars in class name
On every request, Rails checks to see whether any ruby code has been changed on the filesystem. The default FileUpdateChecker does this by iterating over every file on the autoload_paths and comparing its modified-time.
In Discourse, our autoload path of `/app` includes the `/app/assets` directory, and therefore thousands of non-ruby files (e.g. node_modules). This makes the `Dir["/app"]` call very slow (>100ms in my case). On my machine, every Rails-handled request spends around 150-200ms in the FileUpdateChecker. This commit introduces a couple of changes to completely eliminate this wasted time:
- The `/app/assets` directory is excluded from the file watchers. For me, this cut the time spent in the file_watcher to around 50-100ms
- Switches our development config to use the `EventedFileUpdateChecker`, which makes use of the `listen` gem to subscribe to os-specific notifications of changes. This completely removes the `FileUpdateChecker` from the critical path
On my machine, topic_list requests now return in around 80ms (previously >200ms). Live code reload still works as it did before
Some polls with images can be very long. Those which showed a pie chart
for the results had a fixed height set, which meant that some long polls
could be cut off.
* DEV: refactor font sizing into css custom variables
Add font variables as css variables. Allows plugins/themes to update/overwrite the variables and have core pick up changes. This allows for a theme or plugin to overhaul core's font ratios if desired.
Checking for remote should cleanup after itself. Currently each check litters
the /tmp filesystem with checkouts. This patch ensures that update checks
keep the system a bit tidier.
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.
The message in logs will now look like:
```
BadgeGranter::GrantError: Failed to backfill 'Some Badge' badge: {:post_ids=>[]}. Reason: ERROR: column "email" does not exist
LINE 6: ...t id as user_id, current_timestamp as granted_at, email from...
```
Plugins always store their stylesheets under `/assets/stylesheets`, so we can make the glob pattern much more specific. In my local development environment, this increases the speed of `Stylesheet::Manager.max_file_mtime` from ~65ms to ~3ms (20x faster). This significantly improves stylesheet regeneration time, and the responsiveness of the theme admin UI.
Note that this will have negligible effect in production, because in production the value of `max_file_mtime` is aggressively cached.
- ensures footer buttons are aligned
- prevents focus on close button to be much larger than it should be, note that this fix could impact other modals but the current solution is not working, so better fix it differently if needed
This setting allows admin to de/activate automatic trimming of incoming email.
There are instances where it does wonders in trimming all the garbage content and other
instances where it's so bad that it trims the most important part of the email.
FIX: don't remove hidden content using the style attribute when converting HTML to Markdown.
The regexp used was doing more harm than good. It was way too broad.
FIX: properly elide signatures from emails sent with Front App.
This is fairly safe as Front App nicely identifies signatures in the HTML part.
This bug has first been seen when loading similar topics, minimum repro:
- Have a topic named "Something Foo Bar" with a category.
- Call this in console:
```
Discourse.currentUser.store.find("similar-topic", { title: "Something foo bar", raw: "" })
```
- Navigate to latest (no full refresh)
- The category from the topic should have disappeared
The aim of this PR is to improve the topic tracking state JavaScript code and test coverage so further modifications can be made in plugins and in core. This is focused on making topic tracking state changes easier to respond to with callbacks, and changing it so all state modifications go through a single method instead of modifying `this.state` all over the place. I have also tried to improve documentation, make the code clearer and easier to follow, and make it clear what are public and private methods.
The changes I have made here should not break backwards compatibility, though there is no way to tell for sure if other plugin/theme authors are using tracking state methods that are essentially private methods. Any name changes made in the tracking-state.js code have been reflected in core.
----
We now have a `_trackedTopicLimit` in the tracking state. Previously, if a topic was neither new nor unread it was removed from the tracking state; now it is only removed if we are tracking more than `_trackedTopicLimit` topics (which is set to 4000). This is so plugins/themes adding topics with `TopicTrackingState.register_refine_method` can add topics to track that aren't necessarily new or unread, e.g. for totals counts.
Anywhere where we were doing `tracker.states["t" + data.topic_id] = newObject` has now been changed to flow through central `modifyState` and `modifyStateProp` methods. This is so state objects are not modified until they need to be (e.g. sometimes properties are set based on certain conditions) and also so we can run callback functions when the state is modified.
I added `onStateChange` and `onMessageIncrement` methods to register callbacks that are called when the state is changed and when the message count is incremented, respectively. This was done so we no longer need to do things like `@observes("trackingState.states")` in other Ember classes.
I split up giant functions like `sync` and `establishChannels` into smaller functions for readability and testability, and renamed many small functions to _functionName to designate them as private functions which not be called by consumers of `topicTrackingState`. Public functions are now all documented (well...at least ones that are not immediately obvious).
----
On the backend side, I have changed the MessageBus publish events for TopicTrackingState to send back tags and tag IDs for more channels, and done some extra code cleanup and refactoring. Plugins may override `TopicTrackingState.report` so I have made its footprint as small as possible and externalised the main parts of it into other methods.
If the "use_site_small_logo_as_system_avatar" setting is enabled, the site's small logo is displayed as the selected option by the avatar-selector. Choosing a different avatar disables the setting.
