feat: log each online player's position once a minute - #18
Merged

Conversation
Add a "player-pings" option (seconds, default 60, 0 disables). A repeating task records each online player's position as a session row with the new ping action, so purge, per-world config, every storage backend and the existing (user,time) index already handle it. No schema change is needed. "/co lookup a:ping" lists the pings. "a:session" now lists only logins and logouts, and "a:session,ping" lists both. The session API methods keep returning only logins and logouts. Session lookups no longer require the block or click lookup permissions, which they only hit because session actions reuse those ids.

- Around line 57-58: Update the NEXT_PING scheduling logic in PlayerPingListener
so existing player deadlines reflect the current positive interval when a world
or configuration changes it. Track each player’s last ping time and compare
elapsed time against the current interval, or recalculate the deadline when the
interval changes, while preserving the existing disabled-interval behavior.

Summary
player-pingsconfig option: every N seconds (default 60,0disables, per-world configs supported) each online player's position is stored as a row inco_sessionwith a newpingaction (2)./co lookup u:<player> a:pinglists the pings as<player> was online here.with clickable coordinates.a:sessionnow lists only logins and logouts.a:session,pingshows both.(user,time)index already work, with no schema change. Each row is about 40–60 bytes, so 15 players online on average comes to roughly 0.5 GB a year in SQLite.sessionLookup,performSessionLookup) still returns only logins and logouts, so existing callers are unaffected.coreprotect.lookup.blockorcoreprotect.lookup.click. They only needed those because session actions reuse the block action ids, anda:pingwould otherwise have needed click permission.The tick cost is one loop over online players per second. Database writes go through the normal consumer, off the main thread.
Testing
mvn packagepasses.player-pings: 5) with an offline bot that walked 4 blocks every 6 s for 30 s. Result: 1 login row, 5 ping rows following the bot's x position, 1 logout row.a:pingshowed only pings,a:sessiononly login and logout,a:session,pingboth, anda:-sessiononly the logout.player-pings: 0, ran/co reloadand reconnected. The new session logged a login and a logout and no pings.🤖 Generated with Claude Code
