interpreting values from gpgme_get_sig_ulong_attr

[Marshall Rose]

environment:

      gpg = 1.0.7
    gpgme = 0.3.11 (from cvs)

    
i use gpgme_op_verify to verify a detached signature. the call succeeds
and the the r_status parameter is updated to GPGME_SIG_STAT_GOOD.
    
i then enter a loop to determine how many signatures there were by doing this:
    
    for (idx = 0;
	     (fpr = gpgme_get_sig_status (..., idx, NULL, NULL)) != NULL;
	     idx++) {

    }
    
inside the loop i call gpgme_get_sig_ulong_attr on
    
    GPGME_ATTR_VALIDITY   - comes back as 0
    GPGME_ATTR_CREATED    - comes back as a valid date (secs since epoch)
    GPGME_ATTR_EXPIRES    - comes back as 0
    GPGME_ATTR_SIG_STATUS - comes back as GPGME_SIG_STAT_GOOD
    GPGME_ATTR_SIG_SUMMARY - comes back as 0

of the three that come back as zero, i think the validity/summary are
wrong, but maybe i just misunderstand.
    
the reason i think they should be non-zero is because i've assigned a
trust of 5 to the key that did the signing, so i think that, at the very
least it should be
    
    validity = GPGME_VALIDITY_FULL
    summary = GPGME_SIGSUM_VALID | GPGME_SIGSUM_GREEN
    
so, what am i missing here...
    
thanks,
