* Restricted users (#4334): initial implementation
* Add User.IsRestricted & UI to edit it
* Pass user object instead of user id to places where IsRestricted flag matters
* Restricted users: maintain access rows for all referenced repos (incl public)
* Take logged in user & IsRestricted flag into account in org/repo listings, searches and accesses
* Add basic repo access tests for restricted users
Signed-off-by: Manush Dodunekov <manush@stendahls.se>
* Mention restricted users in the faq
Signed-off-by: Manush Dodunekov <manush@stendahls.se>
* Revert unnecessary change `.isUserPartOfOrg` -> `.IsUserPartOfOrg`
Signed-off-by: Manush Dodunekov <manush@stendahls.se>
* Remove unnecessary `org.IsOrganization()` call
Signed-off-by: Manush Dodunekov <manush@stendahls.se>
* Revert to an `int64` keyed `accessMap`
* Add type `userAccess`
* Add convenience func updateUserAccess()
* Turn accessMap into a `map[int64]userAccess`
Signed-off-by: Manush Dodunekov <manush@stendahls.se>
* or even better: `map[int64]*userAccess`
* updateUserAccess(): use tighter syntax as suggested by lafriks
* even tighter
* Avoid extra loop
* Don't disclose limited orgs to unauthenticated users
* Don't assume block only applies to orgs
* Use an array of `VisibleType` for filtering
* fix yet another thinko
* Ok - no need for u
* Revert "Ok - no need for u"
