This is a very simple change, which creates a permanent table in the DB, rather than generating a temporary table when moving posts. This change is about capturing data and any usage will appear in a follow-up.
I did include a new column created_new_topic in the new table, so that it can be easily audited without having to compare destination topic created_at with moved_post records.
The primary key is usually a bigint column, but the foreign key columns
are usually of integer type. This can lead to issues when joining these
columns due to mismatched types and different value ranges.
This was using a temporary plugin / test API to make tests pass. After
more careful consideration, we concluded that it is safe to alter the
tables directly.

The migration that adds the invite link to the sidebar determines the position of the link by looking up the max position that a primary link has and inserts the invite link at the max position plus 1. This approach works fine for most sites, however, sites that have deleted all primary links from the sidebar will fail because the max position will be `nil` which blows up the migration.
This commit addresses this edge case by falling back to looking up the min position of secondary links, or to zero if there're also no secondary links, and then inserts the invite link at the min position minus 1.
This commit adds a new "Invite" link to the sidebar for all users who can invite to the site. Clicking the link opens the invite modal without changing the current route the user is on. Admins can customize the new link or remove it entirely if they wish by editing the sidebar section.

Adds a new site setting and corresponding user preference
to disable smart lists. By default they are enabled, because
this is a better experience for most users. A small number of
users would prefer to not have this enabled.
Smart lists automatically append new items to each
list started in the composer when enter is pressed. If
enter is pressed on an empty list item, it is cleared.
This setting will be removed when the new composer is complete.
Background
When creating webhooks on a site without the Discourse Category Experts plugin installed, the category_experts_unapproved_event and category_experts_approved_event webhook events are getting automatically added to webhooks without a way to disable them.
The category_experts_unapproved_event and category_experts_approved_event webhook events are associated with the Discourse Category Experts plugin so I am moving these webhook events into the Category Experts plugin.
Changes
This PR deletes Category Experts plugin specific webhook event types added into core.
In #29272 we added a backwards-compatible way to prevent duplicate problem check trackers. However, there was a mistake in the PR that would instead create duplicate admin notices. As a result, a number of admins now have multiple copies of the same admin notice in their dashboard.
The root cause was fixed in #29329, preventing new duplicates.
This PR is here to clean up notices that were already created.
Admin notices are meant to be ephemeral. Instead of going through hoops to delete duplicates and update the remaining notices' unstructured field with the correct target, it is a lot less error-prone to delete all notices and let the problem check system re-create them.
The real-time checks run every time the dashboard is loaded, so they will appear to never have been deleted. Any notices related to scheduled checks will be added back on the next run. This will happen within at most one hour, and isn't time sensitive.
We added NULLS NOT DISTINCT to a unique index on problem_check_trackers.
This option is only available in PG15+. It does not in itself break PG13, but restoring a PG15+ backup to PG13 currently errors out. It seems this is an operation that's more common than we first thought.
This commit fixes that by removing the NULLS NOT DISTINCT.
We already have another, backwards-compatible approach to do the same thing in place, so this shouldn't change existing behaviour.
In #29169 we added a NULLS NOT DISTINCT option to the unique index on problem_check_trackers. This is to enforce uniqueness even when the target is NULL. (Postgres considers all NULLs to be distinct by default.)
However, this only works in PG15. In PG13 it does nothing.
This commit adds a default dummy string value __NULL__ to target. Since it's a string, PG13 will be able to correctly identify duplicate records.
Theme modifiers can now be defined as theme settings, this allows for
site operators to override behavior of theme modifiers.
New syntax is:
```
{
...
"modifiers": {
"modifier_name": {
"type": "setting",
"value": "setting_name"
}
}
}
```
This also introduces a new theme modifier for serialize_post_user_badges. Name of badge must match the name of the badge in the badges table. The client-side is updated to load this new data from the post-stream serializer.

Constants should always be only assigned once. The logical OR assignment
of a constant is a relic of the past before we used zeitwerk for
autoloading and had bugs where a file could be loaded twice resulting in
constant redefinition warnings.
The `id` column of `notifications` table and `notification_id` columns
of the other tables have been migrated to bigint in previous commits
(for example, 799a45a).
In order to run the migrations with zero downtime, the data had to be
copied to new columns and swapped, but the old columns have been kept
to allow for rollback. They are no longer needed now.
By default, when checking uniqueness on a tuple for the purposes of enforcing a unique index, PostgreSQL considers NULLs to be distinct values. Because of this we could incorrectly have multiple entries with { identifier: "rails_env", target: nil } created due to race conditions. This would then cause errors at runtime.
* Add migrations to ensure password hash is synced across users & user_passwords
* Persist password-related data in user_passwords instead of users
* Merge User#expire_old_email_tokens with User#expire_tokens_if_password_changed
* Add post deploy migration to mark password-related columns from users table as read-only
* Refactored UserPassword#confirm_password? and changes required to accommodate hashing the password after validations
Anonymous users are "shadow" users created when an existing real user desires to post anonymously. This feature is off by default, but it can be enabled via the `allow_anonymous_posting` site setting. Those shadow users shouldn't be included in the users directory (`/u`).
In 14cf8eacf1, we added the
`user_search_similar_results` site setting which when enabled will use
trigram matching for similarity search in `UserSearch`. However, we
noted that adding the `index_users_on_username_lower_trgm` index is
causing the PG planner to not use the `index_users_on_username_lower`
index when the `=` operator is used against the `username_lower` column.
Based on the PG mailing list discussion where support for the `=`
operator in gist_trgm_ops was being considered, it stated that "I also have checked that btree_gist is preferred over pg_trgm gist
index for equality search." This is however quite different from reality
on our own PG clusters where the btree index is not preferred leading to
significantly slower queries when the `=` operator is used.
Since the pg_trgm gist index is only used for queries when the `user_search_similar_results` site setting
is enabled, we decided to drop the feature instead as it is hidden and
disabled by default. As such, we can consider it experiemental and drop
it without deprecation.

This upgrade is designed to be fully backwards-compatible. Any icon names which have changed will be automatically remapped to the new name. For now, this will happen silently. In future, once core & official themes/plugins have been updated, we will start raising deprecation errors to help theme/plugin authors update their code.

Currently, categories support designating only 1 group as a moderation group on the category. This commit removes the one group limitation and makes it possible to designate multiple groups as mods on a category.

TagUser.rb is used to set user notification levels for a tag, we don't have a unique index on the notification level itself. This means that there might be some weird case where a user may have multiple of the same notification level on a tag.
This PR adds a migration which de-duplicates this based on defaults, where we keep the earliest record in the event there is multiple notification level per-user-per-tag.
* add data migration to keep only unexpired or most recently expired user password
* refactor to 1:1 relationship between User and UserPassword
* add migration to remove redundant indexes on user passwords
The `notifications.id` has been migrated to bigint in previous commit
799a45a291. This commit migrates one of
the related columns, `user_badges.notification_id`, to `bigint`.
The `notifications.id` column is the most probable column to run out of
values. This is because it is an `int` column that has only 2147483647
values and many notifications are generated on a regular basis in an
active community. This commit migrates the column to `bigint`.
These migrations do not use `ALTER TABLE ... COLUMN ... TYPE` in order
to avoid the `ACCESS EXCLUSIVE` lock on the entire table. Instead, they
create a new `bigint` column, copy the values to the new column and
then sets the new column as primary key.
Related columns (see `user_badges`, `shelved_notifications`) will
be migrated in a follow-up commit.
### Why?
Before, all flags were static. Therefore, they were stored in class variables and serialized by SiteSerializer. Recently, we added an option for admins to add their own flags or disable existing flags. Therefore, the class variable had to be dropped because it was unsafe for a multisite environment. However, it started causing performance problems.
### Solution
When a new Flag system is used, instead of using PostActionType, we can serialize Flags and use fragment cache for performance reasons.
At the same time, we are still supporting deprecated `replace_flags` API call. When it is used, we fall back to the old solution and the admin cannot add custom flags. In a couple of months, we will be able to drop that API function and clean that code properly. However, because it may still be used, redis cache was introduced to improve performance.
To test backward compatibility you can add this code to any plugin
```ruby
replace_flags do |flag_settings|
flag_settings.add(
4,
:inappropriate,
topic_type: true,
notify_type: true,
auto_action_type: true,
)
flag_settings.add(1001, :trolling, topic_type: true, notify_type: true, auto_action_type: true)
end
```
