Just in case, before it becomes totally incompatible with HEAD code, I have a patch I never committed, it's about making pcache admin-friendly if it makes any sense.
- a (persistent) counter that reports, for each query, how many times it
evaluated to answerable
- "proxycache-" prefixed statements are passed to the private database.
This allows to avoid ambiguities when applying general database directives in slapd.conf. In fact, it is not clear whether they apply to the proxy database or to the cache database.
If they make sense, I'd like to commit them before slapo-pcache enhancement begins.
