fix(ipip-476): wire dht router to composableRouter#127
Merged
Conversation
…sabled fixes two issues with the GetClosestPeers endpoint: 1. endpoint returned HTTP 200 with empty results instead of actual DHT peers 2. when DHT disabled, returned HTTP 200 with empty results instead of error root cause: during rebase of PR #124 (commit 0dad3f7) when integrating with autoconf refactor (PR #123 / ec76365), the dhtRouters initialization was accidentally omitted from server.go. the autoconf PR renamed getCombinedRouting to combineRouters and changed its signature, but the rebase failed to preserve the dhtRouters creation line that existed in commit 42bd221. changes: - server.go:201-208: add explicit dhtRouters creation with caching and sanitization, similar to original 42bd221 implementation - server.go:232: wire dhtRouters to composableRouter.dht field - server.go:338: update combineRouters signature to accept host.Host parameter needed for GetClosestPeers peerstore lookups - server_routers.go:73-77: return routing.ErrNotSupported instead of empty iterator when DHT is nil, resulting in HTTP 500 instead of misleading HTTP 200 - server_test.go:16,20,24: update combineRouters test calls with new signature - server_dht_test.go:355-379: add test verifying HTTP 500 when DHT disabled

This PR fixes two issues with the GetClosestPeers endpoint:
IIUC during rebase of PR #124 (commit 0dad3f7) when integrating with autoconf refactor (PR #123 / ec76365), the
dhtRoutersinitialization was accidentally omitted fromserver.go. the autoconf PR renamedgetCombinedRoutingtocombineRoutersand changed its signature, but the rebase failed to preserve thedhtRouterscreation line that existed in commit 42bd221.This PR fixes that and now
GET /routing/v1/dht/closest/peers/{cid}returns HTTP 200 with results OR HTTP 500 if DHT is not available.cc @hsanjuan @gammazero for sanity check if I got this right
