Such a measure is the exchange's own explanation 31 * for why it is not paying the account out. 32 * 33 * A measure counts as satisfied once some `legitimization_processes` row 34 * refers to it *and* the account has a `legitimization_outcomes` row that was 35 * decided no earlier than that process started. Both halves are needed: a 36 * process that was started and abandoned decides nothing, and an outcome that 37 * predates the process belongs to an earlier measure. 38 * 39 * This deliberately uses only columns that `taler-auditor-sync` replicates, so 40 * that an external auditor reaches the same verdict as an internal one. In 41 * particular it cannot look at `legitimization_measures.is_finished` or 42 * `legitimization_processes.finished`, neither of which is replicated. 43 * 44 * Primary test table: `legitimization_measures` (see test_legitimization_measures.c). 45 * 46 * @param pg the database context 47 * @param h_payto normalized hash of the payto URI of the account 48 * @param[out] legitimization_measure_serial_id set to the lowest such measure 49 * @param[out] start_time set to when that measure was imposed; the exchange 50 * writes this column at full precision, so it is not a rounded 51 * timestamp 52 * @return #GNUNET_DB_STATUS_SUCCESS_NO_RESULTS if every measure on the 53 * account was decided, including if there never was one 54 */ 55 enum GNUNET_DB_QueryStatus 56 TALER_EXCHANGEDB_get_open_legitimization_measure ( 57 struct TALER_EXCHANGEDB_PostgresContext *pg, 58 const struct TALER_NormalizedPaytoHashP *h_payto, 59 uint64_t *legitimization_measure_serial_id, 60 struct GNUNET_TIME_Absolute *start_time); 61 62 #endif
