To Artifact [fb8d00c06e]:

• File src/db.c — part of check-in [8e85d6ca22] at 2022-12-30 11:53:39 on branch trunk — If there is a need to do lazy updates of the full text index during a request that is not from the same origin, then allow database writes for the duration of that update. Also, allow changes to USER and CONFIG tables when explicitly authorized by db_unprotect() even if the request that prompted the change is not from the same origin. (user: drh size: 165269)
