From 9a5d75225e839204cd41865520731d6f06008a14 Mon Sep 17 00:00:00 2001 From: Chris Toshok Date: Wed, 17 Oct 2001 07:37:39 +0000 Subject: add upgrade from 0.1 to 0.2, where we make sure id dbt's match vcard id's, 2001-10-17 Chris Toshok * 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.
