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
When tagging is enabled, we were correctly serializing tags by their name. However, when tagging was disabled we were attempting to serialize an entire Tag object which raises an error since ee07f6da7d.

`delete_previous!` deletes existing topics even when we cannot send a new one due to the `limit_once_per` option. The dashboard problems PM gets deleted the next time the job runs (30 minutes), so the inbox could be empty when
admins click on the summary notification.
Right now the experimental user menu sorts notifications the same way that the old menu does: unread high-priority notifications are shown first in reverse-chronological order followed by everything else also in reverse-chronological order. However, since the experimental user menu has dedicated tabs for some notification types and each tab displays a badge with the count of unread notifications in the tab, we feel like it makes sense to change how notifications are sorted in the experimental user menu to this:
1. unread high-priority notifications
2. unread regular notifications
3. all read notifications (both high-priority and regular)
4. within each group, notifications are sorted in reverse-chronological order (i.e. newest is shown first).
This new sorting logic applies to all tabs in the experimental user menu, however it doesn't change anything in the old menu. With this change, if a tab in the experimental user menu shows an unread notification badge for a really old notification, it will be surfaced to the top and prevents confusing scenarios where a user sees an unread notification badge on a tab, but the tab doesn't show the unread notification because it's too old to make it to the list.
Internal topic: t72199.
A user could receive more than a notification for the same post if they
watched both the categories and tags at different levels. This commit
makes sure that only the watching notification is created.
* Add DiscourseEvent before post notifications are created
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`
The generate RSA key and import theme routes worked separate from each
other. The RSA key returned both the public and private key and it was
the frontend which posted the private key back to the server. With this
commit, only the public key is necessary as the server keeps a map of
public and private keys that is used to get the private key back from
a public key.
It used to return the next URL anyway which lead to an additional
request. On the frontend, if the result set was empty, it kept retrying
until at least one result was returned. This bug is fixed in this commit
too.
This lets us use all our normal JS tooling like prettier, esline and babel on the splash screen JS. At runtime the JS file is read and inlined into the HTML. This commit also switches us to use a CSP hash rather than a nonce for the splash screen.
* FIX: hide welcome topic banner as soon as the welcome topic is edited
This commit adds a message bus listener on client to hide the welcome
topic banner as soon as the welcome topic is edited.
* update test
* only subscribe when show_welcome_topic_banner is true
* Do not lookup for messageBus service if it's not required
* Remove unneeded code
* Cache result for Site.show_welcome_topic_banner
* Update tests per latest changes
* Changes per PR review
Each new user menu notifications should have their own count. Therefore, we need to include all types to serializer and not only `grouped_unread_high_priority_notifications`
Additional PR will be created for chat and assign plugin, as they will have to switch to `grouped_unread_notifications` as well.
* FIX: Only seed general category on new sites
If the site already has human users (users with an id > 0) don't seed
the categories.
Follow up to: a6ad74c759
* use human_users scope
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.
If a topic is converted to a private message, all posters were invited
to the new private message. This included users who only whispered or
posted small actions.
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.
If a user was granted a trust level, joined a group that granted a trust
level and left the group, the trust level was reset. This commit tries
to restore the last known trust level before joining the group by
looking into staff logs.
This commit also migrates old :change_trust_level user history records
to use previous_value and new_value fields.
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.
Default sidebar tags for not authenticated users can be defined in admin panel. Otherwise, top 5 categories and tags are taken.
Optionally, if categories are set up in permanent order, then the first 5 categories are taken.
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.
The logic was added in commit ec8306835d,
to show the like action even if the user could not like the post. It is
not necessary for this logic to be implemented on the server side.
* 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 logic to determine what post excerpt to show for
a topic-level bookmark based on the last unread post
was complex and slow, so we decided to remove it and
always just use the first post excerpt.
This commit also fixes an issue where a couple of
instances of for_topic were missed when doing the
Bookmarkable refactors, so:
1. Clicking the topic bookmark link was not taking
the user to the last unread post
2. When replying to a topic where there was a topic
level bookmark with the auto delete preference
of "on owner reply", we were not removing the
bookmark from the UI correctly.
A test has been added for the former, the latter would
be quite time-consuming to test and not really worth
it considering it's quite an edge case UI bug.
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.
Previously, for every bookmarked topic, all topic_user records were being preloaded. Only the current user's record is actually required.
This commit introduces a new `perform_custom_preload!` API which bookmarkables can use to add custom preloading logic. We use this in topic_bookmarkable to load just the topic_user data we need (in the same way as `topic_list.rb`).

Handles edge-case when a user is an admin and has an associated reviewable. Hitting this exception should be rare since we clear the reviewable when
granting staff to the user.
