Souzoh confidential and proprietarygolang/goキャッシュビルド導入13● rcs: cmd/go/internal/cache: implement build artifact cache○ https://github.com/golang/go/commit/1114d403fa7d16247a3c569978290d0827f224a1● rcs: cmd/go: cache built packages○ https://github.com/golang/go/commit/de4b6ebf5d0a12f57ace43948b8b1b90f200fae9
Souzoh confidential and proprietary● GOCACHE環境変数が増えた○ go env GOCACHE○ キャッシュファイルが保存されるところ● sha256でハッシュ化され保存される● 二回目以降のビルド時から使用され、既にビルド時間の短縮に繋がっている● 雰囲気はccacheみたいな感じ○ 実装までは まだ追えてません 時間がないので省略golang/goキャッシュビルド導入14
