Currently, the trust level method is calculating trust level based on maximum value from:
- locked trust level
- group automatic trust level
- previously granted trust level by admin
https://github.com/discourse/discourse/blob/main/lib/trust_level.rb#L33
Let's say the user belongs to groups with automatic trust level 1 and in the meantime meets all criteria to get trust level 2.
Each time, a user is removed from a group with automatic trust_level 1, they will be downgraded to trust_level 1 and promoted to trust_level 2
120a2f70a9/lib/promotion.rb (L142)
This will cause duplicated promotion messages.
Therefore, we have to check if the user meets the criteria, before downgrading.
We have all these calls to Group.refresh_automatic_groups! littered throughout the tests. Including tests that are seemingly unrelated to groups. This is because automatic group memberships aren't fabricated when making a vanilla user. There are two places where you'd want to use this:
You have fabricated a user that needs a certain trust level (which is now based on group membership.)
You need the system user to have a certain trust level.
In the first case, we can pass refresh_auto_groups: true to the fabricator instead. This is a more lightweight operation that only considers a single user, instead of all users in all groups.
The second case is no longer a thing after #25400.
The most common thing that we do with fab! is:
fab!(:thing) { Fabricate(:thing) }
This commit adds a shorthand for this which is just simply:
fab!(:thing)
i.e. If you omit the block, then, by default, you'll get a `Fabricate`d object using the fabricator of the same name.
While load testing our user creation code path in production, we
identified that executing the DB statement to update the `Group#user_count` column within a
transaction is creating a bottleneck for us. This is because the
creation of a user and addition of the user to the relevant groups are
done in a transaction. When we execute the DB statement to update
`Group#user_count` for the relevant group, a row level lock is held
until the transaction completes. This row level lock acts like a global
lock when the server is creating users that will be added to the same
group in quick succession.
Instead of updating the counter cache within a transaction which the
default ActiveRecord `counter_cache` option does, we simply update the
counter cache outside of the committing transaction.

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.
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
* DEV: use active record `save!` instead of mini sql.
The "save" method will trigger the before_save callback "match_primary_group_changes" for User model. Else `flair_group_id` won't be removed from the user.
* check whether the method `match_primary_group_changes` called or not.
This is a recent regression introduced by https://github.com/discourse/discourse/pull/12937 which makes it so that when looking at a user profile that is not your own, specifically the category and tag notification settings, you would see your own settings instead of the target user. This is only a problem for admins because regular users cannot see these details for other users.
The issue was that we were using `scope` in the serializer, which refers to the current user, rather than using a scope for the target user via `Guardian.new(user)`.
However, on further inspection the `notification_levels_for` method for `TagUser` and `CategoryUser` did not actually need to be accepting an instance of Guardian, all that it was using it for was to check guardian.anonymous? which is just a fancy way of saying user.blank?. Changed this method to just accept a user instead and send the user in from the serializer.
If a user always read all group messages, we will never update the
`first_pm_unread_at` column since the previous query will not return the
group_user. Instead, we should update `first_pm_unread_at` to the
current timestamp if the user has read everything.
Follow-up to 9b75d95fc6
For sites that are configured to mute some or all categories and tags
for users by default, groups can now be configured to set members'
notification level to normal from the group manage UI.
* FEATURE: set notification levels when added to a group
This feature allows admins and group owners to define default
category and tag tracking levels that will be applied to user
preferences automatically at the time when users are added to the
group. Users are free to change those preferences afterwards.
When removed from a group, the user's notification preferences aren't
changed.
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
