開発者向けテスト版の更新(スナップショット) NOTE: 互換性をしっかりとチェックしていないためテスト用の キャッシュディレクトリを用意することを推奨。 master(82a564b)からの主な変更点 - DAT/HTMLパーサーの機能を強化 - リファクタリング - テストケースを追加 --- FIXME: ChunkedDecoder: heap-buffer-overflow `ChunkedDecoder`のデコード処理で特定の条件のときバッファーオーバーフロー が発生しました。以下の2条件を満たすときバッファの末尾にヌル文字を 書き込もうとしたときバッファの境界を越えるアクセスが起きます。 * 入力の長さと用意したバッファの長さが等しい * デコード結果の長さと入力の長さが等しい ASan report ``` ==182784==ERROR:
