* p2p/dnsdisc: add support for enode.Iterator This changes the dnsdisc.Client API to support the enode.Iterator interface. * p2p/dnsdisc: rate-limit DNS requests * p2p/dnsdisc: preserve linked trees across root updates This improves the way links are handled when the link root changes. Previously, sync would simply remove all links from the current tree and garbage-collect all unreachable trees before syncing the new list of links. This behavior isn't great in certain cases: Consider a structure where trees A, B, and C reference each other and D links to A. If D's link root changed, the sync code would first remove trees A, B and C, only to re-sync them later when the link to A was found again. The fix for this problem is to track the current set of links in each clientTree and removing old links only AFTER all links are synced. * p2p/dnsdisc: deflake iterator test * cmd/devp2p: adapt dnsClient to new p2p/dnsdisc API * p2p/dnsdisc: tiny comment fix |
