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.
Internal topic: t/124648.
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
```

Currently to handle stub topics after merging, there are only options to (1) never delete a stub topic and (2) delete a stub topic after X amount of days. This adds the option to immediately delete a stub topic upon merge.

Previously in these 2 PRs, we introduced a new site setting `SiteSetting.enforce_second_factor_on_external_auth`.
https://github.com/discourse/discourse/pull/27547https://github.com/discourse/discourse/pull/27674
When disabled, it should enforce 2FA for local login with username and password and skip the requirement when authenticating with oauth2.
We stored information about the login method in a secure session but it is not reliable. Therefore, information about the login method is moved to the database.
* FEATURE: Clean up previously logged information after permanently deleting posts
When soft deleteing a topic or post, we will log some details in the
staff log, including the raw content of the post. Before this commit, we
will not clear the information in these records. Therefore, after
permanently deleting the post, `UserHistory` still retains copy of the
permanently deleted post. This is an unexpected behaviour and may raise
some potential legal issues.
This commit adds a behavior that when a post is permanently deleted, the
details column of the `UserHistory` associated with the post will be
overwritten to "(permanently deleted)". At the same time, for permanent
deletion, a new `action_id` is introduced to distinguish it from soft
deletion.

* FEATURE: Add logging for CustomEmoji
We didn't provide any logs for CustomEmoji before, nor did we record the
person who added any emoji in the database. As a result, the staff had
no way to trace back who added a certain emoji.
This commit adds a new column `user_id` to `custom_emojis` to record the
creator of an emoji. At the same time, a log is added for staff logs to
record who added or deleted a custom emoji.
Our old group SMTP SSL option was a checkbox,
but this was not ideal because there are actually
3 different ways SSL can be used when sending
SMTP:
* None
* SSL/TLS
* STARTTLS
We got around this before with specific overrides
for Gmail, but it's not flexible enough and now people
want to use other providers. It's best to be clear,
though it is a technical detail. We provide a way
to test the SMTP settings before saving them so there
should be little chance of messing this up.
This commit also converts GroupEmailSettings to a glimmer
component.
Allow admin to create custom flag which requires an additional message.
I decided to rename the old `custom_flag` into `require_message` as it is more descriptive.

GitHub auth tokens cannot be made with permissions to
access multiple organisations. This is quite limiting.
This commit changes the site setting to be a "secret list"
type, which allows for a key/value mapping where the value
is treated like a password in the UI.
Now when a GitHub URL is requested for oneboxing, the
org name from the URL is used to determine which token
to use for the request.
Just in case anyone used the old site setting already,
there is a migration to create a `default` entry
with that token in the new list setting, and for
a period of time we will consider that token valid to
use for all GitHub oneboxes as well.
