Csaba Kiraly 06c5ce8372 eth/peerstats: split peer quality aggregation out of txtracker ... Introduces a new eth/peerstats package as the single home for per-peer quality metrics consumed by the dropper. txtracker shrinks to a pure tx-lifecycle role: it maps tx hash to deliverer, subscribes to chain heads, computes per-block per-peer inclusion and finalization deltas, and emits them to a StatsConsumer. peerstats owns the aggregates: inclusion EMA, finalized counter, latency EMA, sample counter, and the MinLatencySamples bootstrap constant the dropper uses to filter under-sampled peers. It's a plain struct with a mutex — no goroutine of its own, no lifecycle management. The fetcher's onRequestLatency callback now flows to peerStats.NotifyRequestLatency, the handler's unregisterPeer cleans up via peerStats.NotifyPeerDrop, and the dropper reads its snapshot via peerStats.GetAllPeerStats. txtracker.handleChainHead computes deltas under its own lock, then releases the lock before calling the consumer, which avoids any cross-package lock ordering. Tests are split along the same line: tracker tests use a mock consumer to assert what signals are emitted, peerstats tests cover EMA math and aggregation semantics directly.		2026-04-20 09:30:52 +02:00
