* pull missing changestv35 hours1-0/+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.
* find reachable neighbourstv36 hours1-0/+2
|
* sync with neighbourstv36 hours1-3/+38
|
* add member registrytv36 hours1-0/+1
|
* use nonce in handshaketv37 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 codetv37 hours1-29/+15
|
* no heal during catch-uptv41 hours1-1/+6
|
* peers that just became ready get syncstv41 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 resettv41 hours1-21/+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 triptv41 hours1-62/+52
|
* drop pre-membership sync messagestv41 hours1-23/+4
| | | | | The handshake resets the session anyway, and the sender's reply timeout resends what still matters.
* bump number of heads in keepalive messagestv42 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-uptv42 hours1-1/+7
| | | | This allows changing sources without the fixed 30 s stall duration.
* enrich keepalive contenttv42 hours1-26/+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 peerstv3 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.
