2001-10-17 Chris Toshok <toshok@ximian.com> * backend/pas/pas-backend-file.c (pas_backend_file_upgrade_db): add upgrade from 0.1 to 0.2, where we make sure id dbt's match vcard id's, fixes longstanding bug (#7406) where cards were not modifiable or removable after having been created during a 1-2 week long window in early betas. (PAS_BACKEND_FILE_VERSION): change to 0.2 (PAS_ID_PREFIX): #define this here. (pas_backend_file_create_unique_id): use PAS_ID_PREFIX instead of the string. svn path=/trunk/; revision=13720
