FreeBSD rc.d 経由で daemon(8) 起動した本番環境で、Puma プロセスの fd 0/1/2 が reader のいない pipe を指した状態になり、Sinatra の dump_errors! (STDERR.puts) が Errno::EPIPE で失敗して 500 を返す。 EPIPE が handle_exception! で再 raise されるため、本来の例外内容 が一切ログに残らない。 tomato-shrieker #1442 (1c11177) のパターンを bin/puma_daemon.rb 冒頭 に移植する。空バッファの flush は EPIPE を出さず素通りするため、 mulukhiya 側の「flush 試行→例外時のみ reopen」ではなく、非 tty 時 無条件 reopen 版を採用する。 TTY 直起動 (foreground 開発実行) は io.tty? で除外され影響なし。 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
