* add state filetv36 hours1-0/+1
| | | | | This allows storing the swarm ID and additionally discovered seeds, which prevents a formerly genesis node to start a new document.
* cache headstv2 days1-4/+4
| | | | To reduce the number of write locks, heads are now cached.

|
* add traffic countertv3 days1-0/+4
| | | | | | | | | | 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.

* pull missing changestv3 days1-0/+1
| | | | | | 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.

* use nonce in handshaketv3 days1-2/+14
| | | | | 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.

* no heal during catch-uptv3 days1-1/+6
|
* peers that just became ready get syncstv3 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 resettv3 days1-21/+18
| | | | | | | | | | 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.
* perform handshake in one round triptv3 days1-62/+52
|
* drop pre-membership sync messagestv3 days1-23/+4
| | | | | The handshake resets the session anyway, and the sender's reply timeout resends what still matters.
* bump number of heads in keepalive messagestv3 days1-0/+1
| | | | | Instead of arbitrarily limiting the number to 16, allow filling keepalive messages as long as they don't cause mycelium to chunk it.
* probe sync source during catch-uptv3 days1-1/+7
| | | | This allows changing sources without the fixed 30 s stall duration.
* enrich keepalive contenttv3 days1-26/+39
| | | | | | | Add ready and syncs_with_you flags as well as actual heads, so the peer - ready: same meaning as in the sync message - syncs_with_you: sender counts recipient as member and in same epoch - heads: allows to tell who's behind or if both sides have changes

* don't resend sync messages to up-to-date peerstv4 days1-6/+15
| | | | | | | | | | | When an sync messages arrives and automerge has nothing to say about it, then no reply is generated. With c9279e4 it was assumed that every sync message gets an answer, so missing replies caused unnecessary resends. Now a reply is only awaited if the peer's last reported heads differ from ours. If the peer's heads become equal through a third peer without replying, the waiting will also abort if a ping or pong showss the same heads digest on both sides.
