I can't quite parse that answer, so let's be more specific.
Doc says:
bayes_expiry_max_db_size (default: 150000)
What should be the maximum size of the Bayes tokens database? When
expiry occurs, the Bayes system will keep either 75% of the maximum
value, or 100,000 tokens, whichever has a larger value.
>From this (and the more elaborate description in the EXPIRATION section,
which I've also read) I thought it worked roughly like this:
if (ntokens < bayes_expiry_max_db_size)
do_nothing()
else
goal_ntokens = max(100000, 0.75 * bayes_expiry_max_db_size)
while (ntokens > goal_ntokens)
kill_oldest_tokens()
If I misunderstood, how/where? Sorry for my density :-(
