Please do not do this. Primes *rapidly* get further between as it gets larger. While I don't expect that our memory cache is likely to get larger than a few hundred entries, the processing time necessary to identify a prime number above that will grow prohibitively more difficult. The potential hash-collision avoidance is not worth the cost. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlISGIwACgkQeiVVYja6o6NRGwCgobCv/u5jrFxX9SLdOxQ3V9o2 jHcAnA+2WRVb2MX+HhuUVeHE/W1N1MAM =oz4B -----END PGP SIGNATURE----- _______________________________________________ sssd-devel mailing list [email protected] https://lists.fedorahosted.org/mailman/listinfo/sssd-devel
