2002-07-10 Chris Toshok <toshok@ximian.com> * backend/pas/pas-backend-summary.c (clear_items): actually remove the items from the pointer array too, so an error while loading doesn't leave the memory summary corrupted. (pas_backend_summary_load_header): bleah, load the num_items and summary_mtime in the right order :) Also, set upgraded to TRUE if we loaded a v1.0 summary. (pas_backend_summary_open): make this return a gboolean, return TRUE if the summary is already open (priv->fp != NULL). return FALSE in error conditions. (pas_backend_summary_load): if summary_open returns FALSE, return FALSE, also set the dirty flag to FALSE after we load, and if the summary was upgraded write it out. (pas_backend_summary_save): update the in memory mtime to that of the file when we save. (summary_flush_func): if we're not dirty, do nothing and return. (pas_backend_summary_is_up_to_date): make sure we've opened the summary. (pas_backend_summary_get_summary_vcard): fix compiler warning. svn path=/trunk/; revision=17416
