* add electoratetv14 hours1-8/+101
| | | | | For an upcoming change in remake coordination, nodes now maintain their self-assessed liveness in the document.

|
* add traffic countertv22 hours1-0/+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 changestv23 hours5-5/+159
| | | | | | 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 handshaketv24 hours1-2/+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.
* consolidate backoff codetv24 hours1-29/+15
|
* retry using fresh messagestv25 hours1-158/+127
| | | | | Don't store encoded messages but retry using a newly generated one. That way any accumulated changes can be delivered at once.
* drop stall breaker; resend needed changestv27 hours1-65/+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| | | | | | The stall breaker was superseded by regular re-handshaking Re-handshaking also gets triggered, when a node needs some of the heads its peer believes it has already sent.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-uptv28 hours1-1/+6
|
* peers that just became ready get syncstv28 hours1-0/+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 resettv28 hours3-42/+28
| | | | | | | | | | 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 triptv29 hours3-78/+68
|
* drop pre-membership sync messagestv29 hours3-43/+10
| | | | | The handshake resets the session anyway, and the sender's reply timeout resends what still matters.
* bump number of heads in keepalive messagestv29 hours1-0/+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-uptv29 hours3-106/+14
| | | | This allows changing sources without the fixed 30 s stall duration.
* enrich keepalive contenttv29 hours2-26/+208
| | | | | | | 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
* use only ready peers as sync sourcetv30 hours1-11/+52
| | | | | | Sync messages now carries a ready flag, telling whether the sending peer itself is joined or is itself still (re-)joining. In the latter case, the peer won't be used as sync source.

|
* open sync only from one sidetv45 hours1-3/+21
| | | | | | | | | If both sides open, the openings cross, and an empty node's answer to the other opening (empty heads) makes the other side send the whole document a second time. Now after a sync reset, only the side with the smaller public key opens the sync; the other answers it, or opens itself if nothing arrives.
* don't resend sync messages to up-to-date peerstv2 days2-9/+28
| | | | | | | | | | | 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.
