This new modifier can be used by plugins to modify search ordering.
Specifically plugins such as discourse_solved can amend search ordering
so solved topics bump to the top.
Also correct edge case where low and high sort priority categories did not
order correctly when it came to closed/archived
This commit adds support for the following ordering filters:
1. `order:activity` which orders the topics by `Topic#bumped_at` in descending order
2. `order:activity-asc` which orders the topics by `Topic#bumped_at` in ascending order
3. `order:latest-post` which orders the topics by `Topic#last_posted_at` in descending order
4. `order:latest-post-asc` which orders the topics by `Topic#last_posted_at` in ascending order
5. `order:created` which orders the topics by `Topic#created_at` in descending order
6. `order:created-asc` which orders the topics by `Topic#created_at` in ascending order
7. `order:views` which orders the topics by `Topic#views` in descending order
8. `order:views-asc` which orders the topics by `Topic#views` in ascending order
9. `order:likes` which orders the topics by `Topic#likes` in descending order
10. `order:likes-asc` which orders the topics by `Topic#likes` in ascending order
11. `order:likes-op` which orders the topics by `Post#like_count` of the first post in the topic in descending order
12. `order:likes-op-asc` which orders the topics by `Post#like_count` of the first post in the topic in ascending order
13. `order:posters` which orders the topics by `Topic#participant_count` in descending order
14. `order:posters-asc` which orders the topics by `Topic#participant_count` in ascending order
15. `order:category` which orders the topics by `Category#name` of the topic's category in descending order
16. `order:category-asc` which orders the topics by `Category#name` of the topic's category in ascending order
Multiple order filters can be composed together and the order of ordering is applied based on the position of the filter
in the query string. For example, `order:views order:created` will order the topics by `Topic#views` in descending order
and then order the topics by `Topics#created_at` in descending order.
This commit adds support for the following date filters:
1. `activity-before:<YYYY-MM-DD>` which filters for topics that have been bumped at or before given date
2. `activity-after:<YYYY-MM-DD>` which filters for topics that have been bumped at or after given date
3. `created-before:<YYYY-MM-DD>` which filters for topics that have been created at or before given date
4. `created-after:<YYYY-MM-DD>` which filters for topics that have been created at or after given date
5. `latest-post-before:<YYYY-MM-DD>` which filters for topics with the
latest post posted at or before given date
6. `latest-post-after:<YYYY-MM-DD>` which filters for topics with the
latest post posted at or after given date
If the filter has an invalid value, i.e string that cannot be converted
into a proper date in the `YYYY-MM-DD` format, the filter will be ignored.
If either of each filter is specify multiple times, only the last
occurrence of each filter will be taken into consideration.
Large or broken images are removed from oneboxes, but sometimes images
were removed when they were oneboxed too. The reason is that images can
be oneboxed by the AllowlistedGenericOnebox or ImageOnebox and only
AllowlistedGenericOnebox was handled correctly.
When revising a post, if the topic that post belonged to did not have a category attached it would error with

- Move the old '`define_include_method`' arg to a `respect_plugin_enabled` kwarg
- Introduce an `include_condition` kwarg which can be passed a lambda with inclusion logic. Lambda will be run via `instance_exec` in the context of the serializer instance
This is backwards compatible - old-style invocations will trigger a deprecation message

Update chat and poll plugins to new pattern
Responding to negative behaviour tends to solicit more of the same. Common wisdom states: "don't feed the trolls".
This change codifies that advice by introducing a new nudge when hitting the reply button on a flagged post. It will be shown if either the current user, or two other users (configurable via a site setting) have flagged the post.
* DEV: Support `likes-(min:max):<count>` on `/filter` route
This commit adds support for the following filters:
1. `likes-min`
2. `likes-max`
3. `views-min`
4. `views-max`
5. `likes-op-min`
6. `likes-op-max`
If the filter has an invalid value, i.e string that cannot be converted
into an integer, the filter will be ignored.
If either of each filter is specify multiple times, only the last
occurrence of each filter will be taken into consideration.
This commit adds support for the `posters-min:<count>` and
`posters-max:<count>` filters for the topics filtering query language.
`posters-min:1` will filter for topics with at least a one poster while
`posters-max:3` will filter for topics with a maximum of 3 posters.
If the filter has an invalid value, i.e string that cannot be converted
into an integer, the filter will be ignored.
If either of each filter is specify multiple times, only the last
occurence of each filter will be taken into consideration.
This commit adds support for the `posts-min:<count>` and

`posts-max:3` will filter foor topics with a maximum of 3 posts.
If the filter has an invalid value, i.e string that cannot be converted

When we "pull hotlinked images" on onebox images, they are added to the uploads table and their dominant color is calculated. This commit adds the data to the HTML so that it can be used by the client in the same way as non-onebox images. It also adds specific handling to the new `discourse-lazy-videos` plugin.
This commit adds support for the `created-by:<username>` query filter
which will return topics created by the specified user. Multiple
usernames can be specified by comma seperating the usernames like so:
`created-by:username1,username2`. This will filter for topics created by
either of the specified users. Multiple `created-by:<username>` can also
be composed together. `created-by:username1 created-by:username2` is
equivalent to `created-by:username1,username2`.
This was inadvertently removed in 4c46c7e. In very specific scenarios,
this could be used execute arbitrary JavaScript.
Only affects instances where SVGs are allowed as uploads and CDN is not
configured.
Previously, Discourse's password hashing was hard-coded to a specific algorithm and parameters. Any changes to the algorithm or parameters would essentially invalidate all existing user passwords.
This commit introduces a new `password_algorithm` column on the `users` table. This persists the algorithm/parameters which were use to generate the hash for a given user. All existing rows in the users table are assumed to be using Discourse's current algorithm/parameters. With this data stored per-user in the database, we'll be able to keep existing passwords working while adjusting the algorithm/parameters for newly hashed passwords.
Passwords which were hashed with an old algorithm will be automatically re-hashed with the new algorithm when the user next logs in.
Values in the `password_algorithm` column are based on the PHC string format (https://github.com/P-H-C/phc-string-format/blob/master/phc-sf-spec.md). Discourse's existing algorithm is described by the string `$pbkdf2-sha256$i=64000,l=32$`
To introduce a new algorithm and start using it, make sure it's implemented in the `PasswordHasher` library, then update `User::TARGET_PASSWORD_ALGORITHM`.
This commit adds support for the `in:<topic notification level>` query
filter. As an example, `in:tracking` will filter for topics that the
user is watching. Filtering for multiple topic notification levels can
be done by comma separating the topic notification level keys. For
example, `in:muted,tracking` or `in:muted,tracking,watching`.
Alternatively, the user can also compose multiple filters with `in:muted
in:tracking` which translates to the same behaviour as
`in:muted,tracking`.
This commit adds support for the `in:pinned` filter to the topics filtering
query language. When the filter is present, it will filter for topics
where `Topic#pinned_until` is greater than `Topic#pinned_at`.
This adds a SiteSetting, which when enabled, creates a small_action post for tag/category changes to the topic. It uses `topic.add_moderator_post, and passes raw text in, to describe the change.
Before this commit, composing multiple category filters with a query such as category:category1 and category:category2 would not return any results. This is because we were filtering for topics that belonged to both category1 and category2, which is impossible since a topic can only belong to a single category.
With this commit, specifying a query like category:category1 category:category2 will now translate to filtering for topics that belong to either the category1 or category2 category.
Invite only and Discourse connect could not be enabled at the same time
because of some legacy reason. This is a follow up commit to ce04db8,
355d51a and 40f6ceb.
This commit adds support for filtering for topics in specific
subcategories via the categories filter query language.
For example: `category:documentation:admins` will filter for topics and
subcategory topics in
the category with slug "admins" whose parent category has the slug
"documentation".
The `=` prefix can also be used such that
`=category:documentation:admins` will exclude subcategory topics of the
category with slug "admins" whose parent category has the slug
"documentation".
On the `/filter` route, the categories filtering query language is now
supported in the input per the example provided below:
```
category:bug => topics in the bug category AND all subcategories
=category:bug => topics in the bug category excluding subcategories
category:bug,feature => allow for categories either in bug or feature
=category:bug,feature => allow for exact categories match excluding sub cats
categories: => alias for category
```
Currently composing multiple category filters is not supported as we
have yet to determine what behaviour it should result in. For example,
`category:bug category:feature` would now return topics that are in both
the `bug` and `feature` category but it is not possible for a topic to
belong to two categories.
Add a modifier that will allow us to tune the results returned by suggested.
At the moment the modifier allows us to toggle including random results.
This was created for the discourse-ai module. It needs to switch off random
results when it returns related topics.
Longer term we can use it to toggle unread/new and other aspects.
This also demonstrates how to test the contract when adding modifiers.
Similar to the _map added for group_list SiteSettings in
e62e93f83a, this commit adds
the same extension for simple and compact `list` type SiteSettings,
so developers do not have to do the `.to_s.split("|")` dance
themselves all the time.
For example:
```
SiteSetting.markdown_linkify_tlds
=> "com|net|org|io|onion|co|tv|ru|cn|us|uk|me|de|fr|fi|gov|ddd"
SiteSetting.markdown_linkify_tlds_map
=> ["com", "net", "org", "io", "onion", "co", "tv", "ru", "cn", "us", "uk", "me", "de", "fr", "fi", "gov"]
```
There is no need to validate the user's emails when
promoting/demoting their trust level, this can cause
issues in things like Jobs::Tl3Promotions, we don't
need to fail in that case when all we are doing is changing
trust level.
Introduces a new API for plugin data modification without class-based extension overhead.
This commit introduces a new API that allows plugins to modify data in cases where they return different data rather than additional data, as is common with filtered_registers in DiscoursePluginRegistry. This API removes the need for defining class-based extension points.
When a plugin registers a modifier, it will automatically be called if the plugin is enabled. The core will then modify the parameter sent to it using the block registered by the plugin:
```ruby
DiscoursePluginRegistry.register_modifier(plugin_instance, :magic_sum_modifier) { |a, b| a + b }
sum = DiscoursePluginRegistry.apply_modifier(:magic_sum_filter, 1, 2)
expect(sum).to eq(3)
```
Key features of these modifiers:
- Operate in a stack (first registered, first called)
- Automatically disabled when the plugin is disabled
- Pass the cumulative result of all block invocations to the caller
The following are the changes being introduced in this commit:
1. Instead of mapping the query language to various query params on the
client side, we've decided that the benefits of having a more robust
query language far outweighs the benefits of having a more human readable query params in the URL.
As such, the `/filter` route will just accept a single `q` query param
and the query string will be parsed on the server side.
1. On the `/filter` route, the tags filtering query language is now
supported in the input per the example provided below:
```
tags:bug+feature tagged both bug and feature
tags:bug,feature tagged either bug or feature
-tags:bug+feature excluding topics tagged bug and feature
-tags:bug,feature excluding topics tagged bug or feature
```
The `tags` filter can also be specified multiple
times in the query string like so `tags:bug tags:feature` which will
filter topics that contain both the `bug` tag and `feature` tag. More
complex query like `tags:bug+feature -tags:experimental` will also work.
This change sets the ground work for allowing us to filter topics list
by tags in the following ways:
1. Filter for topics that matches all tags in a given set of tags
2. Filter for topics that matches any tags in a given set of tags
3. Exclude topics that matches all tags in a given set of tags
4. Exclude topics that matches any tags in a given set of tags
When we renamed the `default_categories_regular` to `default_categories_normal` we missed a site setting validation method. It allowed the duplicate category ids in `default_categories_normal` site setting and caused the problem in user registration process.

When setting the ACL for optimized images after setting the
ACL for the linked upload (e.g. via the SyncACLForUploads job),
we were using the optimized image path as the S3 key. This worked
for single sites, however it would fail silently for multisite
sites since the path would be incorrect, because the Discourse.store.upload_path
was not included.
For example, something like this:
somecluster1/optimized/2X/1/3478534853498753984_2_1380x300.png
Instead of:
somecluster1/uploads/somesite1/2X/1/3478534853498753984_2_1380x300.png
The silent failure is still intentional, since we don't want to
break other things because of ACL updates, but now we will update
the ACL correctly for optimized images on multisite sites.
Our SafeMigrate system is designed to prevent tables/columns being dropped in pre-deploy migrations. Its regex-based detection was triggering incorrectly on `ALTER COLUMN DROP NOT NULL`.
There was a lot of duplication in the svg parsing and coercion code. This reduces that duplication and causes svg sprite parsing to happen earlier so that more computation is cached.
Our schema allows `category.topic_id` to be NULL. Null values shouldn't actually happen in production, but it is very common in tests because `Fabricate(:category)` skips creating the definition topic to improve performance. Before this commit, a NULL category.topic_id would cause all subcategory topics to be excluded from a TopicQuery result. This is because, in postgres, `NULL <> anything` is falsy. Instead, we can use `IS DISTINCT FROM`, which will return true when NULL is compared to a non-NULL value.
Why is this change required?
Prior to this change, we would list all group messages that a user
has access to in the user menu messages notifications panel dropdown.
However, this did not respect the topic's notification level setting and
group messages which the user has set to 'normal' notification level were
being displayed
What does this commit do?
With this commit, we no longer display all group messages that a user
has access to. Instead, we only display group messages that a user is
watching in the user menu messages notifications panel dropdown.
Internal Ref: /t/94392
Follow up to 4d2a95ffe6. Sometimes
due to the original UploadReference migration or other issues,
multiple UploadReference records can have the exact same
created_at date and time. To tiebreak and correct the SQL order
when this happens, we can add a secondary `id ASC` ordering
when we check for the first upload reference.
Similar spirit to e195e6f614,
this moves the Bookmarkable registration to DiscoursePluginRegistry
so plugins which are not enabled do not register additional
bookmarkable classes.
When a theme setting of type `upload` has a default upload, it should return the URL of the specified default upload until a custom upload is used for the setting. However, currently this isn't the case and we get null instead of the default upload URL.
The reason for this is because the `super` method of `#value` already returns the default upload URL (if there's one), so we can't pass that to `cdn_url` which expects an upload ID:
c961dcc757/lib/theme_settings_manager.rb (L212)
This commit fixes the bug by skipping the call to `cdn_url` when we fallback to the default upload for the setting value.

Follow up to 098ab29d41. Since
we just used a `cattr_reader` on `About` this was not safe
for multisite, since some sites could have the chat plugin
enabled and some may not. Using `DiscoursePluginRegistry` gets
around this issue, and makes it so the chat stats only show
for a site if `chat_enabled` is true.
Sometimes we get Maps URL containing a zoom level as a float (17.5z and
not 17z) but this doesn’t work with our current onebox implementation.
While Google accepts those float zoom levels, it removes automatically
the floating part in the URL (thus when visiting a Maps URL containing
17.5z, the URL will be rewritten shortly after as 17z). When putting a
float zoom level in an embedded URL, this actually breaks (Maps API
returns a 400 error).
This patch addresses the issue by allowing the onebox engine to match on
a zoom level expressed as a float but we only keep the integer part thus
rendering properly maps.
This commit implements many changes to topic and comments embedding. It
deprecates the class_name field from EmbeddableHost and suggests using
the className parameter. discourse_username parameter has been
deprecated and it will fetch it from embedded site from the author or
discourse-username meta.
See the updated code sample from Admin > Customize > Embedding page.
* FEATURE: Add className parameter for Discourse embed
* DEV: Hide class_name from EmbeddableHost
* DEV: Deprecate class_name field of EmbeddableHost

Original solution to use `description` instead of `text_description` was wrong: https://github.com/discourse/discourse/pull/20436
Problem is that we have to escape HTML tags.
However, we would like to use escape method which is keep `/` intact. Expected behavior is given by ERB::Util.html_escape instead of Rack::Utils.escape_html
/t/92015
When invoking e.g. `can_see?(Foo.new)`, the guardian checks if there's a method `#can_see_foo?` defined and if so uses that to determine whether the user can see it or not.
When such a method is not defined, the guardian currently returns `true`, but it is probably a better call (pun intended) to make it "safe by default" and return `false` instead. I.e. if you can't explicitly see it, you can't see it at all.
This change makes the change to `Guardian#can_see?` to fall back to `false` if no visibility check method is defined.
For `#can_see_user?` and `#can_see_tag?` we don't have any particular logic that prevents viewing. We previously relied on the implicit `true` value, but since that's now change to `false`, I have explicitly implemented these two methods in `UserGuardian` and `TagGuardian` modules. If in the future we want to add some logic for it, this would be the place.
To be clear, **the behaviour remains the same**, but the `true` value is now explicit rather than implicit.
The current default timeout is hardcoded to 2 seconds which is proving
too low for certain cases, and resulting in sporadic timeouts due to slow DNS queries.
As of ba3f62f576, handlebars templates are colocated with js files so the path to hbs templates referenced by this rake task is no longer valid. This commit fixes the path to hbs templates and updates a couple of files that are generated by the rake task.
- Reduce duplication of terms in post index from unlimited to 6. This will
result in reduced index size and reduced weighting for posts containing
a huge amount of duplicate terms. (Eg: a post containing "sam sam sam sam
sam sam sam sam", will index as "sam sam sam sam sam sam", only including
the word up to 6 times.) This corrects a flaw where title weighting could
be ignored.
- Prioritize exact matches of words in titles. Our search always performs
a prefix match. However we want to give special weight to exact title matches
meaning that a search for "sum" will find topics such as "the sum of us" vs
"summer in spring".
- Pick up fixes to our search algorithm which are missing from old indexes.
Specifically pick up the fix that indexes URLs properly. (`https://happy.com`
was stemmed to `happi` in keywords and then was not searchable)
see also:
https://meta.discourse.org/t/refinements-to-search-being-tested-on-meta/254158
Indexing will take a while and work in batches, in the background.
This commit adds backend support for a new topics list that combines both the current unread and new topics lists. We're going to experiment with this new list (name TBD) internally and decide if this feature is something that we want to fully build.
Internal topic: t/77234.
* FIX: do not notify admins on suppressed categories
Avoid notifying admins on categories where they are not explicitly members
in cases where SiteSetting.suppress_secured_categories_from_admin is
enabled.
This helps keep notification stream clean and avoids admins mistakenly
being invited to discussions that should be suppressed
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.
There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.
This PR is a major change to Sass compilation in Discourse.
The new version of sass-ruby moves to dart-sass putting we back on the supported version of Sass. It does so while keeping compatibility with the existing method signatures, so minimal change is needed in Discourse for this change.
This moves us
From:
- sassc 2.0.1 (Feb 2019)
- libsass 3.5.2 (May 2018)
To:
- dart-sass 1.58

SCSS files have been migrated automatically using `sass-migrator division app/assets/stylesheets/**/*.scss`
Previously due to an error archived topics were more prominent in search
than closed topics.
This amends our internal logic to ensure archived topics are bumped down
the list.
If a post contains domain with a word that stems to a non prefix single
words will not match it.
For example: in happy.com, `happy` stems to `happi`. Thus searches for happy
will not find URLs with it included.
This bloats the index a tiny bit, but impact is limited.
Will require a full reindex of search to take effect.
When we are done refining search we can consider a full version bump.
Previously to_tsquery would split terms and join with &
In PG 14 terms are split and use <-> which means followed directly by.
In PG 13:
discourse_test=# SELECT to_tsquery('english', '''hello world''');
to_tsquery
---------------------
'hello' & 'world'
(1 row)
In PG 14:
discourse_test=# SELECT to_tsquery('english', '''hello world''');
to_tsquery
---------------------
'hello' <-> 'world'
(1 row)
Change is very unobtrosive, we simply amend our to_tsquery to behave like
it used to behave and make no use of the `<->` operator
More detail at: https://akorotkov.github.io/blog/2021/05/22/pg-14-query-parsing/
Note that plainto_tsquery used elsewhere in Discourse keeps the exact
same function.
This also corrects a faulty test that was passing by a fluke on older
version of PG
We've had a couple of problems with the R2 gem where it generated a broken RTL CSS bundle that caused a badly broken layout when Discourse is used in an RTL language, see a3ce93b and 5926386. For this reason, we're replacing R2 with `rtlcss` that can handle modern CSS features better than R2 does.
`rltcss` is written in JS and available as an npm package. Calling the `rltcss` from rubyland is done via the `rtlcss_wrapper` gem which contains a distributable copy of the `rtlcss` package and loads/calls it with Mini Racer. See https://github.com/discourse/rtlcss_wrapper for more details.

The new `prioritize_exact_search_match` can be used to force the search
algorithm to prioritize exact term matches in title when ranking results.
This is scoped narrowly to titles for cases such as a topic titled:
"organisation chart" and a search of "org chart".
If we scoped this wider, all discussion about "org chart" would float to
the top and leave a very common title de-prioritized.
This is a hidden site setting and it has some performance impact due
to double ranking.
That said, performance impact is somewhat mitigated cause ranking on
title alone is a very cheap operation.
