概要
dns.resolve4()依存からdns.lookup(..., { family: 4 })ベースへ変更しましたqueryA EREFUSED platform.claude.comが発生して OAuth ログインできない問題を回避しますorigin/masterに preload 本体がないため、再導入コミットもあわせて含まれます変更理由
dns.resolve4()は system resolver を経由せず、VPN 提供 DNS と相性が悪い環境でAquery が拒否されていましたdns.lookup(..., { family: 4 })なら macOS / VPN の resolver を使いながら IPv4 固定を維持できます影響ファイル
.claude/bun-ipv4-preload.js.zshrcsymlink.sh手動確認
node -e 'require("node:dns").resolve4("platform.claude.com", (err) => { console.log(String(err)); process.exit(err ? 1 : 0); })'でqueryA EREFUSED platform.claude.comを確認\n-node -e 'require("node:dns").lookup("platform.claude.com", { family: 4, all: true }, (err, addrs) => { console.log(err ? String(err) : JSON.stringify(addrs)); process.exit(err ? 1 : 0); })'で IPv4 解決成功を確認\n-node --import ./.claude/bun-ipv4-preload.js -e 'import https from "node:https"; await new Promise((resolve, reject) => { const req = https.get("https://platform.claude.com", (res) => { console.log(res.statusCode); res.resume(); res.on("end", resolve); }); req.on("error", reject); });'で200を確認\n-node --import ./.claude/bun-ipv4-preload.js -e 'console.log("preload ok")'で preload の構文読み込みを確認\n
