* split state moduletv13 days1-1297/+0

* add clock moduletv13 days1-8/+7
| | | | | The Clock module is the system clock that every unix timestamp new goes through. It comes with an offset that only tests can set.
* avoid stalled sourcetv13 days1-0/+3
| | | | | | | | | | | | | A source given up for not answering our sync messages could become the source again straight away. Whoever asks first after the reset takes the role, and that's often the same peer, which would then stall for another delivery limit. Now, a stalled source isn't chosen again for one more delivery_limit. If it's the only candidate, catching up waits that long and then tries it again. Before, a retry with that peer couldn't have helped any sooner anyway: a source is only given up after a whole delivery limit without a sync message, and that clock restarts when it is chosen again.

* add traffic countertv2026-10-241-0/+2
| | | | | | | | | | 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 changestv2026-10-241-0/+2
| | | | | | 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 handshaketv2026-10-241-0/+3
| | | | | 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.

* retry using fresh messagestv2026-10-241-11/+52
| | | | | 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 divergencetv2026-10-241-6/+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 changestv2026-10-241-17/+0
| | | | | | The stall breaker was superseded by regular re-handshaking Re-handshaking also gets triggered, when a node needs some of the heads its peer believes it has already sent.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.
* both sides may open sync after resettv2026-10-231-121/+26
| | | | | | | | | | 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 triptv2026-10-231-5/+0
|
* drop pre-membership sync messagestv2026-10-231-4/+0
| | | | | The handshake resets the session anyway, and the sender's reply timeout resends what still matters.
* bump number of heads in keepalive messagestv2026-10-231-0/+4
| | | | | 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-uptv2026-10-231-3/+14
| | | | This allows changing sources without the fixed 30 s stall duration.
* enrich keepalive contenttv2026-10-231-5/+9
| | | | | | | 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 sourcetv2026-10-231-0/+4
| | | | | | 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.
* catch up with a single source onlytv2026-10-231-0/+15

* introduce announce opening varianttv2026-10-231-6/+14
| | | | | This prevents a fall back to the 3 s grace period if a reset happens between the epoch switch and our opening went out.
