688,P3,bittorrent-dht,failed to handle duplicate bt source when concurrent download with metalink,unsupported-behavior,duplicate-bt-source-handling,no-code,"No code fix applied. Source review confirms aria2 models each active BitTorrent download by unique infoHash: RequestGroup.cc rejects a second active BT RequestGroup for the same infoHash through BtRegistry, which matches the reported errorCode=12. Metalink grouping with metaurl@name can map multiple entries into one dependant RequestGroup, but BtDependency.cc resolves torrent file entries by originalName and cannot fan out one torrent file to multiple output names. The maintainer comment also identifies the requested behavior as same content under different names using the same torrent, which aria2 does not support. A correct implementation would require a new post-download copy/link fan-out model, not a duplicate-source bug fix."

Source review shows aria2.addTorrent and torrent files loaded after aria2.addUri both converge on createRequestGroupForBitTorrent and bittorrent::processRootDictionary, so there is no separate URL-loaded infohash calculation path in current source. processRootDictionary computes the v1 infohash from bencode2::encode(infoDict), and Dict uses std::map ordering, giving canonical key ordering for hybrid torrents that still contain the v1 pieces field. The maintainer could not reproduce the report, and the reporter later suggested a local or Windows build-specific problem. No sample torrent is available in the retained issue data to reproduce a wrong hash."
