We recently tried to default the normalize_emails site setting to true to avoid spam. What this does is it considers e-mails the same regardless of plus addressing, e.g. bob+1@mail.com == bob+2@mail.com. This caused some problems for SSO users.
This PR makes it so that DiscourseConnect never normalizes e-mails.
The normalize_emails setting makes it so that only canonical e-mails are considered for validation purposes. This means disallowing "plus addressing". For example, with this enabled, bob@discourse.org and bob+foo@discourse.org are considered the same address, and you can only sign up with one of them.
Currently this is disabled by default, leading to a lot of spam sign-ups. It's healthier to consider this an opt-out setting.
We're seeing errors in logs due to some sites setting the reserved_usernames setting to nil. This is causing multiple use cases upstream of User#reserved_username? to error out.
This commit changes from using the raw #reserved_usernames to using the #reserved_usernames_map helper which exists on list-type site settings. It returns an empty array if the raw value is nil or empty string.
This commit fixes a regression introduced in 8979adc where under certain conditions the groups syncing logic in Discourse Connect would try to add users to groups they're already members of and cause errors when users try to sign in using Discourse Connect.
Discourse Connect can be used to manage group memberships of users by including a `add_groups`, `remove_groups` or `groups` attribute in the Discourse Connect payload. However, additions/deletions of users from groups aren't logged to the groups logs (available at `/g/<group>/manage/logs`) which can cause confusions to admins they try to figure out when/how users were added or removed from a group. This commit makes Discourse Connect add entries to the groups logs when it makes changes to users' group memberships.
This commit introduces a new site setting: `use_name_for_username_suggestions` (default true)
Admins can disable it if they want to stop using Name values when generating usernames for users. This can be useful if you want to keep real names private-by-default or, when used in conjunction with the `use_email_for_username_and_name_suggestions` setting, you would prefer to use email-based username suggestions.
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.
