[ Fixes (almost certainly) #24649, #25494, #27351, and other LDAP search
2002-08-26 Chris Toshok <toshok@ximian.com> [ Fixes (almost certainly) #24649, #25494, #27351, and other LDAP search crashes ] * backend/pas/pas-backend-ldap.c (view_destroy): use an EList instead of a GList to store the book_view's so we don't have weird issues with modifying the list while it's being traversed. (find_book_view): same. (create_card_handler): same. (remove_card_handler): same. (modify_card_modify_handler): same. (poll_ldap): same, and also ref the book_view before calling ldap_search_op_timeout (and therefore send_pending_adds). (ldap_search_handler): same. (ldap_op_add): warn about conflicting ldap msgid's (shouldn't ever happen..) (homephone_populate): make this a bit more robust (if values[0] == NULL, values[1] won't be valid). (business_populate): same. (build_card_from_entry): break out of the prop_info loop when we get a match, and only set the simple field if the value != NULL. (ldap_search_dtor): free all the pending adds stuff. (pas_backend_ldap_process_get_book_view): g_list_prepend => e_list_append. (pas_backend_ldap_remove_client): simplify the removing of the book (use g_list_remove instead of searching and then using g_list_remove_link.) (pas_backend_ldap_destroy): unref the book_views list. (pas_backend_ldap_init): initialize the EList for book_views. svn path=/trunk/; revision=17870
