IPFSのハッシュを自動的に収集できるのではないかということに気がついた。 スイカネットを流れるデータを拾って集める横浜駅SFのワンシーンを思い出してテンションが上がった。

ログを見る

ipfs log tail でイベントのログを見ることができる。 どのイベントが何を意味するのか、ドキュメントは見つけられなかった。

イベント名を抽出してみる。

$ ipfs log tail | jq ".event" | awk '!colname[$1]++{print $1}'
"updatePeer"
"handleFindPeerBegin"
"handleFindPeer"
"Bitswap.Rebroadcast.idle"
"handleAddProviderBegin"
"handleAddProvider"
"tptDialReusePort"
"connDial"
"swarmDialDo"
"swarmDialBackoffAdd"
"swarmDialAttemptStart"
"swarmDialAttemptSync"
"getClosestPeers"
"swarmDialAttemptSyncBegin"
"dhtSentMessage"
"swarmDialAttemptStartBegin"
"swarmDialDoBegin"
"interfaceListenAddresses"
"provide"
"provideBegin"
"getClosestPeersBegin"
"findPeerSingleBegin"
"dhtReceivedMessage"
"findPeerSingle"
"connDialBegin"
"tptDialReusePortBegin"
"connLifetime"
"handleGetProvidersBegin"
"handleGetProviders"
"connDialZeroAddr"
"handleGetValueBegin"
"handleGetValue"
"swarmDialBackoff"
"connLifetimeBegin"
"secureHandshakeBegin"
"secureHandshake"
"swarmDialDoSetupBegin"
"swarmDialDoSetup"
"swarmDialBackoffClear"
"periodicBootstrapBegin"
"bootstrapSkip"
"periodicBootstrap"

このうちhandleGetProvidersというイベントは 「誰かがipfs dht findprovしたか、ゲートウェイ等で自動的に呼ばれたかで、ハッシュと対応したコンテンツを持っていないかを他のノードが聞いてきた」 という意味のイベント（だと思う）。 つまり、このイベントをキャッチすれば誰かがアクセスしようとしたハッシュを収集できる。

$ ipfs log tail | grep '"handleGetProviders"' -m 1 --line-buffered | jq

{
  "duration": 2045973,
  "event": "handleGetProviders",
  "key": "QmXLjNdoUETwAi8bErpc73FQEESTovBscu5XaC2wnpgfpY",
  "peer": "QmX9Nhr56k7K2JBQbu9JBpF2s1AQk8WpmZc6v4sqZERMRu",
  "session": "8e57bece-9c9d-400f-b0ff-ab616dcdfe91",
  "system": "dht",
  "time": "2017-11-10T06:56:50.517580514Z"
}

keyが、誰かが探そうとしているハッシュだと思う。 とりあえず200件ほど集めてみる。 それなりに時間がかかる。

$ ipfs log tail | grep '"handleGetProviders"' -m 200 --line-buffered | jq ".key" -r --unbuffered >> hashes.txt
$ cat hashes.txt

このなかでアクセスできるハッシュだけをフィルタする。 ゲートウェイでのアクセスに失敗した時にipfs resolve -rのエラーメッセージが出ていた気がするので、それを使う。 これまたものすごく時間がかかる。

$ cat hashes.txt | xargs -I hash timeout 60 ipfs resolve -r hash 2>/dev/null | sed '/^$/d' >> resolve.txt

40件くらいに減ってしまった。 ファイル名が入っているが肝心の中身にアクセスできない壊れたディレクトリオブジェクトや、 フォーマットのわからないバイナリがほとんどである。 そもそものユーザ数が少ないため、読めるデータもだいたい WikipediaのHTML（ページ内のすべてがリンク切れ） やWikipediaの画像だったりする。 これはWikipediaがトルコでブロックされたために作られたスナップショットのものだと思う。

Uncensorable Wikipedia on IPFS

そんな中によくわからない画像や テキストがある。 面白くはない。 あえて言うならば癒やしである。
