* bound stable-hub degreetv6 days1-4/+46
| | | | | | Each stable member can be preferred at most by 4*k members. The budget is spent in key order, which is the same on every node, so the graph stays deterministic, symmetric and connected.

* cache headstv6 days7-24/+61
| | | | To reduce the number of write locks, heads are now cached.

|
* being caught up needs some headstv6 days1-5/+9
| | | | | | | | | | | A sync message from a ready peer only completes the initial sync if that peer has at least one head. A peer with an empty document can no longer make a joiner ready on an empty store: a misconfigured second swarm, or a genesis node in its first seconds. Effect on a brand-new swarm: a joiner now waits until the genesis node has registered itself in the member list, which happens within about 5 s of it becoming ready.

* add traffic countertv6 days9-12/+270
| | | | | | | | | | This introduces a new wrapper that counts messages and payload bytes per peer, split by kind (hello, helloReply, sync, ping, pong), each sent, received and refused. The traffic counter goes around the firewall, which means messages dropped outbound are still counted as sent, and messages dropped inbound don't count as received.

| | | | | | Nodes push changes to their neighbours but don't relay them directly. In a partial mesh, nodes can learn about missing changes via keepalive messages and can pull them from their neighbours.

| | | | | To prevent stale hello replies to cause joins and thus stale sessions, each run gets a random ID, which used as nonce in the handshake.

| | | | | Don't store encoded messages but retry using a newly generated one. That way any accumulated changes can be delivered at once.
* heal from noticed divergencetv7 days1-6/+27
| | | | | Wait 2*keepalive but at least 20 s to trigger resync so that lost messages can be resent first.

* drop stall breaker; resend needed changestv7 days2-82/+21
| | | | | | The stall breaker was superseded by regular re-handshaking Re-handshaking also gets triggered, when a node needs some of the heads its peer believes it has already sent. In that case the peer now resends what's needed.
* no heal during catch-uptv7 days1-1/+6
|
* peers that just became ready get syncstv7 days1-0/+9
| | | | | | When keepalive says ready and we didn't have taht on record before, the peer is queued for sync. Hello and hello reply don't do this because the handshake already queues a sync.
* both sides may open sync after resettv7 days6-163/+64
| | | | | | | | | | Ready nodes will leave the first message to the pear that isn't ready. Hello and hello reply now carry ready, so readiness is known from the very first contact, before any sync. Together with the sync messages and keepalives, reports_ready is always current. After epoch switch, pings go to everyone except ready members already on the new epoch, these learn from the lagging peer's opening.

* drop pre-membership sync messagestv7 days4-47/+10
| | | | | The handshake resets the session anyway, and the sender's reply timeout resends what still matters.
