We previously had a system which would generate a 10x10px preview of images and add their URLs in a data-small-upload attribute. The client would then use that as the background-image of the `<img>` element. This works reasonably well on fast connections, but on slower connections it can take a few seconds for the placeholders to appear. The act of loading the placeholders can also break or delay the loading of the 'real' images.
This commit replaces the placeholder logic with a new approach. Instead of a 10x10px preview, we use imagemagick to calculate the average color of an image and store it in the database. The hex color value then added as a `data-dominant-color` attribute on the `<img>` element, and the client can use this as a `background-color` on the element while the real image is loading. That means no extra HTTP request is required, and so the placeholder color can appear instantly.
Dominant color will be calculated:
1. When a new upload is created
2. During a post rebake, if the dominant color is missing from an upload, it will be calculated and stored
3. Every 15 minutes, 25 old upload records are fetched and their dominant color calculated and stored. (part of the existing PeriodicalUpdates job)
Existing posts will continue to use the old 10x10px placeholder system until they are next rebaked
Upgrading to Markdown.it v13 broke empty inline BBCodes. This works around the problem by adding an empty token before a closing token if the previous token was a BBCode token.
It also removes the unused `jump` attribute which was removed in Markdown.it v12.3
Previously we were relying on a highly-customized version of the unmaintained Barber gem for theme template compilation. This commit switches us to use our own DiscourseJsProcessor, which makes use of more modern patterns and will be easier to maintain going forward.
In summary:
- Refactors DiscourseJsProcessor to move multiline JS heredocs into a companion `discourse-js-processor.js` file
- Use MiniRacer's `.call` method to avoid manually escaping JS strings
- Move Theme template AST transformers into DiscourseJsProcessor, and formalise interface for extending RawHandlebars AST transformations
- Update Ember template compilation to use a babel-based approach, just like Ember CLI. This gives each template its own ES6 module rather than directly assigning `Ember.TEMPLATES` values
- Improve testing of template compilation (and move some tests from `theme_javascript_compiler_spec.rb` to `discourse_js_processor_spec.rb`

We don't want to save the auto_delete_preference for bookmarks to the
user options if it was passed through as nil from the frontend,
this leads to confusion for the end user since they did not explicitly set it.
It's fine to create the bookmark with the default of "never" if no
auto_delete_preference is provided since it applies only to the
single bookmark, not future bookmarks.
- Seed the General category so that the general chat channel will have
a home
- Do not seed the Lounge category anymore
- Move the "Welcome to Site" topic to the General category
This commit makes a number of improvements to the DiscourseJsProcessor:
1. Remove dependence on the out-of-date Ember template compiler from the ember-rails gem; switch to modern template compiler
2. Refactor to make use of a proper module system with `define`/`require`
3. Introduce `babel-plugin-ember-template-compilation` to enable inline hbs compilation
The `mini-loader` is upgraded to support relative lookup and `require.has`, so that these new JS packages work correctly.
Topic allowed user records were created for small actions, which lead to
the system user being invited in many private topics when the user
removed themselves or if a group was invited but some members already
had access.
This commits skips creating topic allowed user. They are already skipped
for the whisper posts.
When preloading topic_list data we were giving it a 'preload key' which was loosely based on the parameters of the list. However, it did not include all parameters, and mismatches between client/server-side logic would cause the preloaded data to be ignored.
This commit simplifies things by using a single key for all topic_list preloading. This works on the assumption that "The first topic_list the JS app will load is the one which was preloaded". That assumption also existed to some extent in the old design, so we don't expect any regressions here.
In a multisite Discourse reported that no backup is running after 60 seconds because the Redis key expired. Also, the thread that listens for a shutdown signal stopped running immediately because it didn't detect a running operation.
Certain HTML can be rejected by nokogumbo, specifically cases where there
are enormous amounts of attributes
This ensures that malformed HTML is simply skipped instead of leaking out
an exception and terminating downstream processes.
* FIX: Do not allow to remove like if topic is archived
* FIX: Always show like button
The like button used to be hidden if the topic was archived and it had
no likes. This commit changes that to always show the like button, but
with a not-allowed cursor if the topic is archived.
`TopicQueryParams` allows for `match_all_tags` to be passed as a query parameter. `TagsController` forces the value to be true.
This change allows a value to be passed, and only sets it to true if no value has been set. It then uses `ActiveModel::Type::Boolean.new.cast` to compare the value.
The maximum_staged_users_per_email site setting controls how many
staged users will be invited to the topic created from an incoming
email. Previously, it counted only the new staged users.
Twitter removed OpenGraph tags from their pages. We can no longer
extract all the information (for example, the quoted tweet) we need
to render Oneboxes without using their API.
Dead and large images are replaced with a placeholder, either a broken
chain icon or a short text. This commit no longer applies this
transformation for images inside Oneboxes, but removes them instead.
This is a much better description of its function. It performs idempotent normalization of a URL. If consumers truly need to `encode` a URL (including double-encoding of existing encoded entities), they can use the existing `.encode` method.
normalized_encode in addressable has a number of issues, including https://github.com/sporkmonger/addressable/issues/472
To temporaily work around those issues for the majority of cases, we try parsing with `::URI`. If that fails (e.g. due to non-ascii characters) then we will fall back to addressable.
Hopefully we can simplify this back to `Addressable::URI.normalized_encode` in the future.
This commit also adds support for unicode domain names and emoji domain names with escape_uri.
This removes an unneeded hack checking for pre-signed urls, which are now handled by the general case due to starting off valid and only being minimally normalized. Previous test case continues to pass.
UrlHelper.s3_presigned_url? which was somewhat wide was removed.

This commit introduces several fine-grained methods
to UserCommScreener which can be used to show the actor
who they are ignoring/muting/blocking DMs from in order
to prevent them initiating conversation with those users
or to display relevant information in the UI to the
actor.
This will be used in a companion PR in discourse-chat,

* FEATURE: track stats around failing scheduled jobs
Discourse.job_exception_stats can now be used to gather stats around how
many regular scheduled jobs failed in the current process.
This will be consumed by the Prometheus plugin and potentially other
monitoring plugins.
* FEATURE: Add case-sensitivity flag to watched_words
Currently, all watched words are matched case-insensitively. This flag
allows a watched word to be flagged for case-sensitive matching.
To allow allow for backwards compatibility the flag is set to false by
default.
* FEATURE: Support case-sensitive creation of Watched Words via API
Extend admin creation and upload of Watched Words to support case
sensitive flag. This lays the ground work for supporting
case-insensitive matching of Watched Words.
Support for an extra column has also been introduced for the Watched
Words upload CSV file. The new column structure is as follows:
word,replacement,case_sentive
* FEATURE: Enable case-sensitive matching of Watched Words
WordWatcher's word_matcher_regexp now returns a list of regular
expressions instead of one case-insensitive regular expression.
With the ability to flag a Watched Word as case-sensitive, an action
can have words of both sensitivities.This makes the use of the global
Regexp::IGNORECASE flag added to all words problematic.
To get around platform limitations around the use of subexpression level
switches/flags, a list of regular expressions is returned instead, one for each
case sensitivity.
Word matching has also been updated to use this list of regular expressions
instead of one.
* FEATURE: Use case-sensitive regular expressions for Watched Words
Update Watched Words regular expressions matching and processing to handle
the extra metadata which comes along with the introduction of
case-sensitive Watched Words.
This allows case-sensitive Watched Words to matched as such.
* DEV: Simplify type casting of case-sensitive flag from uploads
Use builtin semantics instead of a custom method for converting
string case flags in uploaded Watched Words to boolean.
* UX: Add case-sensitivity details to Admin Watched Words UI
Update Watched Word form to include a toggle for case-sensitivity.
This also adds support for, case-sensitive testing and matching of Watched Word
in the admin UI.
* DEV: Code improvements from review feedback
- Extract watched word regex creation out to a utility function
- Make JS array presence check more explicit and readable
* DEV: Extract Watched Word regex creation to utility function
Clean-up work from review feedback. Reduce code duplication.
* DEV: Rename word_matcher_regexp to word_matcher_regexp_list
Since a list is returned now instead of a single regular expression,
change `word_matcher_regexp` to `word_matcher_regexp_list` to better communicate
this change.
* DEV: Incorporate WordWatcher updates from upstream
Resolve conflicts and ensure apply_to_text does not remove non-word characters in matches
that aren't at the beginning of the line.
Fixes edge case from fa5f3e228c.
In case the acting user is sent in with the target_user_ids,
we do not need to load those preferences, because even if the
acting user is preventing PMs or muting etc they need to always be able to
send themselves messages.
The "everyone" group is an automatic group and GroupUser records do not
exist for it. This commit allows all users if the group everyone is one
of the groups in the setting "pm_tags_allowed_for_groups".
* FIX: Rejected emails should not be cleaned up before their logs
If we delete the rejected emails before we delete their associated logs
we will receive 404 errors trying to inspect an email message for that
log.

Currently when generating oneboxes if the connection timeouts and we’re
using the `FinalDestination#get` method, then it raises an exception.
We already catch this exception when using the
`FinalDestination#resolve` method so this patch just applies the same
logic to `FinalDestination#get`.
All other tests that are setting grade_period use either unitless `0`, `1.minute` or `5.minutes` so it wasn't clear if `5` was meant to be seconds (it was)
Our theme system is very complex and it can take a while to figure out how to invalidate the various types of caches that are used throughout the theme system. So, having a single helper method that invalidates everything can be useful in emergency situations where there is no time to read through the code and figure out how to clear the various caches.
Internal ticket: t64732.
When a topic was published from a shared draft and it had tags, the
users watching the tags were not notified. The problem was that the
topics are usually created in a secret category and publishing it just
moves an existent topic to the target category, without making any
changes to the tags.
Tag edit notifications are either created by PostActionNotifier or
PostRevisor. PostActionNotifier already checks if the site setting is
enabled. but PostRevisor scheduled a NotifyTagChange job without
checking disable_tags_edit_notifications.
This commit introduces a new plugin API to register
a group of stats that will be included in about.json
and also conditionally in the site about UI at /about.
The usage is like this:
```ruby
register_about_stat_group("chat_messages", show_in_ui: true) do
{
last_day: 1,
"7_days" => 10,
"30_days" => 100,
count: 1000,
previous_30_days: 120
}
end
```
In reality the stats will be generated any way the implementer
chooses within the plugin. The `last_day`, `7_days`, `30_days,` and `count`
keys must be present but apart from that additional stats may be added.
Only those core 4 stat keys will be shown in the UI, but everything will be shown
in about.json.
The stat group name is used to prefix the stats in about.json like so:
```json
"chat_messages_last_day": 2322,
"chat_messages_7_days": 2322,
"chat_messages_30_days": 2322,
"chat_messages_count": 2322,
```
The `show_in_ui` option (default false) is used to determine whether the
group of stats is shown on the site About page in the Site Statistics
table. Some stats may be needed purely for reporting purposes and thus
do not need to be shown in the UI to admins/users. An extension to the Site
serializer, `displayed_about_plugin_stat_groups`, has been added so this
can be inspected on the client-side.
It makes more sense to use user_ids for the UserCommScreener
introduced in fa5f3e228c since
in most cases the ID will be available, not the username. This
was discovered while starting work on a plugin that will
use this. In the cases where only usernames are available
the extra query is negligble.
The idea behind this refactor is to centralise all of the user ignoring / muting / disallow PM checks in a single place, so they can be used consistently in core as well as for plugins like chat, while improving the main bulk of the checks to run in a single fast non-AR query.
Also fixed up the invite error when someone is muting/ignoring the user that is trying to invite them to the topic.
Previously the spec was hardcoded to expect a certain compiled result. The precise result will change as we update to more recent Ember versions.
Instead, we can compile via the special theme compiler, and then compile our expected result via the normal compiler. If they match, then things are working as intended. This technique should be safe across template-compiler upgrades.
* FIX: min/max username length limits weren't validated
The custom validators introduced in e0d7cda made so we ignored the mix
and max values set on site_settings.yml. That change allowed admins to
set values outside of the range defined on the yaml file.

Logging out failed when the current user was cached by an instance of `Auth::DefaultCurrentUserProvider` and `#log_off_user` was called on a different instance of that class.
Co-authored-by: Sam <sam.saffron@gmail.com>
This happened when a middleware accessed the `currentUser` before a controller had a chance to populate the `action_dispatch.request.path_parameters` env variable. In that case Discourse would always cache `nil` as `currentUser`.
Before, whispers were only available for staff members.
Config has been changed to allow to configure privileged groups with access to whispers. Post migration was added to move from the old setting into the new one.
I considered having a boolean column `whisperer` on user model similar to `admin/moderator` for performance reason. Finally, I decided to keep looking for groups as queries are only done for current user and didn't notice any N+1 queries.

This PR introduces a new hidden site setting that allows admins to display a splash screen while site assets load.
The splash screen can be enabled via the `splash_screen` hidden site setting.
This is what the splash screen currently looks like

Once site assets load, the splash screen is automatically removed.
To control the loading text that shows in the splash screen, you can change the preloader_text translation string in admin > customize > text
Future versions of redis will validate this port number causing the tests
relying on this to fail with:
```
Redis::CommandError:
ERR Invalid master port

Also change from an IPv4 address that might feasibly be in use to an IPv6
random ULA address that almost *certainly* won't be.
At some point in the past we decided to rename the 'regular' notification state of topics/categories to 'normal'. However, some UI copy was missed when the initial renaming was done so this commit changes the spots that were missed to the new name.

This doesn't cope well with gzipped, binary, or large responses. Ideally we would teach FinalDestination to safely retrieve and decode some of the response body. But for now, let's remove the broken implementation.
This reverts commit 94c3bbc2d1.
At this current point in time, we do not have enough data on whether
this centralisation is the trade-offs of coupling features into a single
channel.
When sending emails with delivery_method_options -> return_response
set to true, the SMTP sending code inside Mail will return the SMTP
response when calling deliver! for mail within the app. This commit
ensures that Email::Sender captures this response if it is returned
and stores it against the EmailLog created for the sent email.
A follow up PR will make this visible within the admin email UI.
* FIX: Fix a bug that is accessing the values in a hash wrongly and write tests
I decided to write tests in order to be confident in my refactor that's in the next commit.
Meanwhile I have discovered a potential bug. The `title_attr` key was accessed as a string,
but all the keys are actually symbols so it was never evaluated to be true.
irb(main):025:0> d = {key: 'value'}
=> {:key=>"value"}
irb(main):026:0> d['key']
=> nil
irb(main):027:0> d[:key]
=> "value"
* DEV: Extract methods for readability
I will be adding a new method following the conventions in place for adding a new normalizer. And this will make the readability of the `raw` block even more difficult; so I am extracting self contained private methods beforehand.
* FEATURE: Parse JSON-LD and introduce Movie object
JSON LD data is very easily transferable to Ruby objects because they contain types. If these types are mapped to Ruby objects, it is also better to make all the parsed data very explicit and easily extendable.
JSON-LD has many more standardized item types, with a full list here: https://schema.org/docs/full.html
However in order to decrease the scope, I only adapted the movie type.
* DEV: Change inheritance between normalizers
Normalizers are not supposed to have an inheritance relationships amongst each other. They are all normalizers, but all normalizing separate protocols. This is why I chose to extract a parent class and relieve Open Graph off that responsibility. Removing the parent class altogether could also a possibility, but I am keeping the scope limited to having a more accurate representation of the normalizers while making it easier to add a new one.
* Lint changes
* Bring back the Oembed OpenGraph inheritance
There is one test that caught that this inheritance was necessary. I still think modelling wise this inheritance shouldn't exist, but this can be tackled separately.
* Return empty hash if the json received is invalid
Before this change if there was a parsing error with JSON it would throw an exception. The goal of this commit is to rescue that exception and then log a warning. I chose to use Discourse's logger wrapper `warn_exception` to have the backtrace and not just used Rails logger. I considered raising an `InvalidParameters` error however if the JSON here is invalid it should not block showing of the Onebox, so logging is enough.
* Prep to support more JSONLD schema types with case
* Extract mustache template object created from JSONLD
This PR changes the rescue block to rescue only Net::TimeoutError exceptions and removes the log line to prevent clutter the logs with errors that are ignored. Other errors can bubble up because they're errors we probably want to know about

Following the Rails 7 upgrade, the `DISCOURSE_SMTP_ENABLE_START_TLS`
setting doesn’t work anymore. This is because Rails upgraded the
`net-smtp` gem to the 0.3.1 version which enables `starttls` by default.
The `mail` gem doesn’t support this new behavior yet and doesn’t know
how to disable TLS. This should be fixed in an upcoming release.
Meanwhile applying this patch allows us to get back the previous
behavior which is expected by many.

```

to
```
PostReplyKey.create_or_find_by!

But I don't think it is working as a 1-1 replacement because of the
`Validation failed: Post has already been taken` error we are receiving
with this change. Also we need to make sure we don't re-introduce any
concurrency issues.

Twitter does not allow SVGs to be used for twitter:image
metadata (see https://developer.twitter.com/en/docs/twitter-for-websites/cards/overview/markup)
so we should fall back to the site logo if the image option
provided to `crawlable_meta_data` or SiteSetting.site_twitter_summary_large_image_url
is an SVG, and do not add the meta tag for twitter:image at all
if the site logo is an SVG.
In 7328a2bfb0 we changed the
InlineOneboxer#onebox_for method to run the title of the
onebox through WatchedWord#censor_text. However, it is
allowable for the title to be nil, which was causing this
error in production:
> NoMethodError : undefined method gsub for nil:NilClass
We just need to check whether the title is nil before trying
to censor it.
Previously we hardcoded the DOWNLOAD_URL_EXPIRES_AFTER_SECONDS const
inside S3Helper to be 5 minutes (300 seconds). For various reasons,
some hosted sites may need this to be longer for other integrations.
The maximum expiry time for presigned URLs is 1 week (which is
604800 seconds), so that has been added as a validation on the
setting as well. The setting is hidden because 99% of the time
it should not be changed.
