2b839abUpdate chainparams comment for more info on service bits per dnsseed (Matt Corallo)62e7642Fall back to oneshot for DNS Seeds which don't support filtering. (Matt Corallo)51ae766Use GetDesireableServiceFlags in static seeds, document this. (Matt Corallo)fb6f6b1bluematt's testnet-seed now supports x9 (and is just a static list) (Matt Corallo) Pull request description:4440710broke inserting entries into addrman from dnsseeds which did not support service bits, as well as static seeds. Static seeds were already being filtered by UA for 0.13.1+ (ie NODE_WITNESS), so simply changing the default service bits to include NODE_WITNESS (and updating docs appropriately) is sufficient. For DNS Seeds, not supporting NODE_WITNESS is no longer useful, so instead use non-filtering seeds as oneshot hosts irrespective of named proxy. I've set my testnet-seed to also support x9, though because it is simply a static host, it may be useful to leave the support off so that it is used as a oneshot to get addresses from a live node instead. I'm fine with either. Tree-SHA512: 3f17d4d2b0b84d876981c962d2b44cb0c8f95f52c56a48c6b35fd882f6d7a40805f320ec452985a1c0b34aebddb1922709156c3ceccd1b9f8363fd7cb537d21d
