Why this change?
In `PostDestroyer#make_previous_post_the_last_one` and
`Topic.reset_highest`, we have a query that looks something like this:
```
SELECT user_id FROM posts
WHERE topic_id = :topic_id AND
deleted_at IS NULL AND
post_type <> 4
#{post_type}
ORDER BY created_at desc
LIMIT 1
```
However, we currently don't have an index that caters directly to this
query. As a result, we have seen this query performing poorly on large
sites if the PG planner ends up using an index that is suboptimal for
the query.
This commit adds an index to the `posts` table on `topic_id` and then
`created_at`. For the query above, PG will be able to do a backwards
index scan efficiently.
After deleting SiteSetting::ALLOWLIST_DEPRECATED_SITE_SETTINGS, we found out this was referenced in a migration file. This PR inlines the constant into the migration file to prevent it from erroring out.
Performing a `Delete User`/`Delete and Block User` reviewable actions for a
queued post reviewable from the `review.show` route results in an error
popup even if the action completes successfully.
This happens because unlike other reviewable types, a user delete action
on a queued post reviewable results in the deletion of the reviewable
itself. A subsequent attempt to reload the reviewable record results in
404. The deletion happens as part of the call to `UserDestroyer` which
includes a step for destroying reviewables created by the user being
destroyed. At the root of this is the creator of the queued post
being set as the creator of the reviewable as instead of the system
user.
This change assigns the creator of the reviewable to the system user and
uses the more approapriate `target_created_by` column for the creator of the
post being queued.
Simplified query based on SiteSettings to join only relevant user_options rows.
In addition, index was added to 'watched_precedence_over_muted` column in `user_options` table to speed up query
This PR adds a feature to help admins stay up-to-date with their translations. We already have protections preventing admins from problems when they update their overrides. This change adds some protection in the other direction (where translations change in core due to an upgrade) by creating a notice for admins when defaults have changed.
Terms:
- In the case where Discourse core changes the default translation, the translation override is considered "outdated".
- In the case above where interpolation keys were changed from the ones the override is using, it is considered "invalid".
- If none of the above applies, the override is considered "up to date".
How does it work?
There are a few pieces that makes this work:
- When an admin creates or updates a translation override, we store the original translation at the time of write. (This is used to detect changes later on.)
- There is a background job that runs once every day and checks for outdated and invalid overrides, and marks them as such.
- When there are any outdated or invalid overrides, a notice is shown in admin dashboard with a link to the text customization page.
Known limitations
The link from the dashboard links to the default locale text customization page. Given there might be invalid overrides in multiple languages, I'm not sure what we could do here. Consideration for future improvement.
Recently, site setting watched_precedence_over_muted was introduced - https://github.com/discourse/discourse/pull/22252
In this PR, we are allowing users to override it. The option is only displayed when the user has watched categories and muted tags, or vice versa.
Why this change?
We are currently not fully satisfied with the current way to edit the
categories and tags that appears in the sidebar where the user is
redirected to the tracking preferences tab in the user's profile causing
the user to lose context of the current page. In addition, the dropdown
to select categories or tags limits the amount of information we can
display.
Since editing or adding a custom categories section is already using a
modal, we have decided to switch editing the categories and tags that
appear in the sidebar to use a modal as well.
This commit removes the `new_edit_sidebar_categories_tags_interface_groups` site setting and
make the modals the default for all users.
Updates the interface for implementing summarization strategies and adds a cache layer to summarize topics once.
The cache stores the final summary and each chunk used to build it, which will be useful when we have to extend or rebuild it.
This PR splits up the preference that controls the count vs dot and destination of sidebar links, which is really hard to understand, into 2 simpler checkboxes:
The new preferences/checkboxes are off by default, but there are database migrations to switch the old preference to the new ones so that existing users don't have to update their preferences to keep their preferred behavior of sidebar links when this changed is rolled out.
Internal topic: t/103529.
Communities can use sidebar or header dropdown, therefore navigation menu is a better name settings in 2 places:
- Old user sidebar preferences;
- Site setting about default tags and categories.
* DEV: move sidebar community section to database
Before, community section was hard-coded. In the future, we are planning to allow admins to edit it. Therefore, it has to be moved to database to `custom_sections` table.
Few steps and simplifications has to be made:
- custom section was hidden behind `enable_custom_sidebar_sections` feature flag. It has to be deleted so all forums, see community section;
- migration to add `section_type` column to sidebar section to show it is a special type;
- migration to add `segment` column to sidebar links to determine if link should be displayed in primary section or in more section;
- simplify more section to have one level only (secondary section links are merged);
- ensure that links like `everything` are correctly tracking state;
- make user an anonymous links position consistence. For example, from now on `faq` link for user and anonymous is visible in more tab;
- delete old community-section template.
* FEATURE: add a setting to allowlist DiscourseConnect return path domains
This commit adds a site setting to allowlist DiscourseConnect return
path domains. The setting needs supports exact domain or wildcard
character (*) to allow for any domain as return path.
* Add more specs to clarify what is allowed in site setting
* Update setting description to explain what is allowed
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`.
We use schema_migration_details to determine the age of a site in multiple migrations. This commit moves the logic into a dedicated `Migration::Helpers` module so that it doesn't need to be re-implemented every time.
We perform lookups on sidebar section links based on sidebar_section_id
totally ignoring user. This ensures we have an index to work with.
This removes the previous index `links_user_id_section_id_position` which
partially doubled up `idx_unique_sidebar_section_links`
Currently the auto-bump cooldown is hard-coded to 24 hours.
This change makes the highlighted 24 hours part configurable (defaulting to 24 hours), and the rest of the process remains the same.
This uses the new CategorySetting model associated with Category. We decided to add this because we want to move away from custom fields due to the lack of type casting and validations, but we want to keep the loading of these optional as they are not needed for almost all of the flows.
Category settings will be back-filled to all categories as part of this change, and creating a new category will now also create a category setting.
That column is obsolete since we added the `granted_title_badge_id` column in 2019 (56d3e29a69). Having both columns can lead to inconsistencies (mostly due to old data from before 2019).
For example, `BadgeGranter.revoke_ungranted_titles!` doesn't work correctly if `badge_granted_title` is `false` while `granted_title_badge_id` points to the badge that is used as title.
With the introduction of the sidebar navigation menu, the design team at
Discourse redesigned the user profile navigation to better coexist with
the sidebar.
Fixes migration introduced in a90ad52dff,
some category custom fields like `num_auto_bump_daily` which should be
an integer are actually empty string ''.
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 is the first in a multi-part change to move the custom fields to a new table. It includes:
- Adding a new CategorySetting model and corresponding table.
- Populating it with data from the category_custom_fields table.

What was fixed:
- [x] Use ember transitions instead of full reload
- [x] Link was inaccurately kept active
- [x] "+ save" renamed to just "save"
- [x] Render emojis in link name
- [x] UI to set icon
- [x] Delete link is trash icon instead of "x"
- [x] Add another link to on the left and rewording
- [x] Raname "link name" -> "name", "points to" -> link
- [x] Add limits to fields
- [x] Move add section button to the bottom
Allows users to configure their own custom sidebar sections with links withing Discourse instance. Links can be passed as relative path, for example "/tags" or full URL.
Only path is saved in DB, so when Discourse domain is changed, links will be still valid.
Feature is hidden behind SiteSetting.enable_custom_sidebar_sections. This hidden setting determines the group which members have access to this new feature.
Currently, when doing `@mention` for users we have 0 tolerance for typos and misspellings.
With this patch, if a user search doesn't return enough results we go and use `pg_trgm` features to try and find more matches based on trigrams of usernames and names.
It also introduces GiST indexes on those fields in order to improve performance of this search, going from 130ms down to 15ms in my tests.
This is all gated in a feature flag and can be enabled by running `SiteSetting.user_search_similar_results = true` in the rails console.
This commits adds a database migration to limit the user status to 100
characters, limits the user status in the UI and makes sure that the
emoji is valid.
