What's Changed

Added

  • gateway: Config.MaxDeserializedResponseSize allows setting a maximum file/directory size for deserialized gateway responses. Content exceeding this limit returns 410 Gone, directing users to run their own IPFS node. Trustless response formats (application/vnd.ipld.raw, application/vnd.ipld.car) are not affected. The size is read from the UnixFS root block, so no extra block fetches are needed for the check. #1138
  • gateway: Config.MaxUnixFSDAGResponseSize allows setting a maximum content size applied to all response formats (deserialized, raw blocks, CAR, TAR). Content exceeding this limit returns 410 Gone. For most handlers the check reuses size information already available in the request path; for CAR responses a lightweight Head call is made only when the limit is configured. #1138

Changed

  • bitswap/server: the default peer comparator now schedules peers fairly. A peer that has never been served, or has waited longer than 10s, outranks non-starved peers. Pending counts cap at 16 for ordering purposes, so peers with small wantlists no longer wait behind peers with large ones. The final tiebreak uses a per-process salted hash of peer.ID, so no peer can craft an ID that permanently outranks everyone. Engines built with WithTaskComparator keep their existing behavior. #1141
  • upgrade to go-libp2p-kad-dht v0.39.1

Fixed

  • bitswap/network/bsnet: SendMessage and handleNewStream now close streams in a background goroutine. Previously, stream.Close could hold the caller for up to DefaultNegotiationTimeout (10s) while lazyClientConn.Close waited for the remote peer to complete the multistream handshake. This saturated the bitswap TaskWorkerCount pool when peers were unresponsive and stopped bitswap from serving blocks to other peers. As a side effect, SendMessage no longer returns errors from stream.Close; close failures are logged at Debug. #1142
  • bitswap/server: a peer with a single pending want no longer waits behind peers with large wantlists. #1141
  • pinner/dspinner: RecursiveKeys and DirectKeys now snapshot the pin index under the read lock and release it before emitting pins, so a slow consumer (e.g. the reprovider draining the channel at DHT speed under Provide.Strategy=pinned*) can no longer starve Pin/Unpin/Flush writers. #1140
