The server used to respond with a generic 'error, contact admin' message
which did not offer any hint what the error was. This happened even when
the error could be easily corrected by the user (for example, if they
chose a very common password).
We used to generate invite keys that were 32-characters long which were
not very friendly and lead to very long links. This commit changes the
generation method to use almost all alphanumeric characters to produce
a 10-character long invite key.
This commit also introduces a rate limit for redeeming invites because
the probability of guessing an invite key has increased.
When invited by email, users will receive an invite URL which contains
a token. If that token is present when the invite is redeemed, their
account will be automatically activated.
In Improve invite system, a newly created link only invite cannot
be retrieved via API with the invitee's email once created. A new
route, /invites/retrieve, is introduced to fetch an already
created invite by email address.
Admins can use bulk invites to pre-populate user fields. The imported
CSV file must have a header with "email" column (first position) and
names of the user fields (exact match).
Under the hood, the bulk invite will create staged users and populate
the user fields of those.
This commit ensures that email validation is skipped when the email is
obfuscated, that the email is no longer send when it is not an invite
link and no username is suggested if the email is hidden as it may
reveal the first part of the email.

This PR allows invitations to be used when the DiscourseConnect SSO is enabled for a site (`enable_discourse_connect`) and local logins are disabled. Previously invites could not be accepted with SSO enabled simply because we did not have the code paths to handle that logic.
The invitation methods that are supported include:
* Inviting people to groups via email address
* Inviting people to topics via email address
* Using invitation links generated by the Invite Users UI in the /my/invited/pending route
The flow works like this:
1. User visits an invite URL
2. The normal invitation validations (redemptions/expiry) happen at that point
3. We store the invite key in a secure session
4. The user clicks "Accept Invitation and Continue" (see below)
5. The user is redirected to /session/sso then to the SSO provider URL then back to /session/sso_login
6. We retrieve the invite based on the invite key in secure session. We revalidate the invitation. We show an error to the user if it is not valid. An additional check here for invites with an email specified is to check the SSO email matches the invite email
7. If the invite is OK we create the user via the normal SSO methods
8. We redeem the invite and activate the user. We clear the invite key in secure session.
9. If the invite had a topic we redirect the user there, otherwise we redirect to /
Note that we decided for SSO-based invites the `must_approve_users` site setting is ignored, because the invite is a form of pre-approval, and because regular non-staff users cannot send out email invites or generally invite to the forum in this case.

* FIX: Do not show expired invites under Pending tab
* DEV: Controller action was renamed in previous commit
* FEATURE: Add 'Expired' tab to invites
* FEATURE: Refresh model after removing expired invites
* FEATURE: Do not immediately add invite to the list
Opening the 'create-invite' modal used to automatically generate an
invite to reserve an invite link. If the user did not save it and
closed the modal, the invite would be destroyed. This operations caused
the invite list to change in the background and confuse users.
* FEATURE: Sort redeemed users by creation time
* UX: Improve show / hide advanced options link
* FIX: Show redeemed users even if invites were trashed
* UX: Change modal title when editing invite
* UX: Remove Get Link button
Users can get it from the edit modal
* FEATURE: Add limit for invite links generated by regular users
* FEATURE: Add option to skip email
* UX: Show better error messages
* FIX: Show "Invited by" even if invite was trashed

* FEATURE: Add button to save without sending email
Follow up to c86379a465f28a3cc64a4a8c939cf32cf2931659.
* DEV: Use a buffer to hold all changed data
* FEATURE: Close modal after save
* FEATURE: Rate limit resend invite email
* FEATURE: Make the save buttons smarter
* FEATURE: Do not always send email even for new invites
A missing email when accepting an invite link does not make sense so we
should make it a required param which helps to catch bugs in our test
suite and also prevent potential bugs in our code base when the code
trips on a `nil` email.
The user interface has been reorganized to show email and link invites
in the same screen. Staff has more control over creating and updating
invites. Bulk invite has also been improved with better explanations.
On the server side, many code paths for email and link invites have
been merged to avoid duplicated logic. The API returns better responses
with more appropriate HTTP status codes.
The 'Discourse SSO' protocol is being rebranded to DiscourseConnect. This should help to reduce confusion when 'SSO' is used in the generic sense.
This commit aims to:
- Rename `sso_` site settings. DiscourseConnect specific ones are prefixed `discourse_connect_`. Generic settings are prefixed `auth_`
- Add (server-side-only) backwards compatibility for the old setting names, with deprecation notices
- Copy `site_settings` database records to the new names
- Rename relevant translation keys
- Update relevant translations
This commit does **not** aim to:
- Rename any Ruby classes or methods. This might be done in a future commit
- Change any URLs. This would break existing integrations
- Make any changes to the protocol. This would break existing integrations
- Change any functionality. Further normalization across DiscourseConnect and other auth methods will be done separately
The risks are:
- There is no backwards compatibility for site settings on the client-side. Accessing auth-related site settings in Javascript is fairly rare, and an error on the client side would not be security-critical.
- If a plugin is monkey-patching parts of the auth process, changes to locale keys could cause broken error messages. This should also be unlikely. The old site setting names remain functional, so security-related overrides will remain working.
A follow-up commit will be made with a post-deploy migration to delete the old `site_settings` rows.
* Add timezone to user_options table
* Also migrate existing timezone values from UserCustomField,
which is where the discourse-calendar plugin is storing them
* Allow user to change their core timezone from Profile
* Auto guess & set timezone on login & invite accept & signup
* Serialize user_options.timezone for group members. this is so discourse-group-timezones can access the core user timezone, as it is being removed in discourse-calendar.
* Annotate user_option with timezone
* Validate timezone values
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
Do not send an activation email to users invited via email. They
already confirmed their email address by clicking the invite link.
Users invited via link will need to confirm their email address before
they can login.
