* add possibility to start with a documenttv9 days4-13/+163
| | | | The --recover-from option allows a node start with a given document.
* add state filetv9 days7-4/+266
| | | | | This allows storing the swarm ID and additionally discovered seeds, which prevents a formerly genesis node to start a new document.
* put swarm ID into the documenttv9 days4-6/+27
|
* add genesis flag and never give uptv9 days3-76/+112
| | | | | | | | | The --genesis flag has been introduced to start with a new document. This prevents restarts to accidentally start with a new document and accept reads/writes, causing a second swarm to appear. Additionally, bootstrapping doesn't timeout anymore as that's of no use for nobody.
* compact remake fixes base at the committv10 days5-40/+138
| | | | | | | Instead of fixing base heads at when proposed, compact fixes them when committing. This shrinks the window where writes can be lost if their author restarts to the switch delay; during replace and import remakes writes can still be lost during the voting period.

* bound stable-hub degreetv10 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.

| | | | To reduce the number of write locks, heads are now cached.

|
* being caught up needs some headstv10 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 countertv11 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.
