Logmon now captures the share diff from ckpool's "Possible block
solve" line preceding the confirmation and attaches it to the
BlockEvent. Persisted as share_diff alongside height/hash/reward
and rendered as a new column in the dashboard block history.
Adds RPC.GetBlock(hash, verbosity=2) and a CoinbaseReward
helper that sums the first tx's outputs. IngestBlockEvents
now does getblockhash -> getblock -> sum(vout) so
BlockRecord.RewardBT carries the actual BTC paid out on
solve instead of always being zero. Both RPC calls share a
single 5s deadline and are best-effort — bitcoind being
down just leaves the reward at zero.
New internal/store package wraps modernc.org/sqlite (pure Go,
no CGO) with a BlockStore that exposes Open/Close/InsertBlock/
Recent. The aggregator now accepts an optional *store.BlockStore;
on Run() it loads up to maxBlockHistory rows from the store before
the first refresh, and each ingested block gets written to the
DB before being appended to the in-memory ring.
main.go opens the store at cfg.DBPath and logs a warning + falls
back to in-memory-only if the file can't be created — a broken
data volume shouldn't stop the pool from running.
InsertBlock uses INSERT OR IGNORE on the height primary key so
replayed log events after a restart are harmless.
Adds real-time block detection via ckpool log tailing and a push
channel for the upcoming Svelte UI, all stdlib-only:
- logmon.Tailer follows ckpool.log with rotation/truncation survival
(inode + size tracking) and parses "Solved and confirmed block N"
into BlockEvent values.
- state.Aggregator grows a 256-entry block ring, an OnRefresh hook,
and IngestBlockEvents which best-effort enriches events with the
block hash via bitcoind getblockhash.
- httpapi.Hub implements RFC 6455 from scratch (SHA1 handshake,
unmasked text frames out, masked frames in, ping keepalive,
per-client write mutex, slow-client drop) so we don't pull in a
ws dependency before we can go mod tidy.
- New routes: GET /api/blocks and GET /api/ws. Snapshot pushes fire
on every poll tick and immediately on block-solve.
ZMQ hashblock subscription and SQLite persistence are deferred to
Phase 2b.5 once the s9pk packaging repo exists and we have a real
build environment for adding Go deps.
