    # AI 時代的 Legacy Code 營救術 - 墨嗓 (陳佑竹) {%hackmd o8oUosN0QnqMSkF1_6kH7g %} #### 📚 議程介紹 {%preview https://webconf.tw/agenda/39 %} ###### ▼▼▼ 開始筆記 ▼▼▼ - 簡報:[20251212 AI 時代的 Legacy Code 營救術 2025 WebConf - Speaker Deck](https://speakerdeck.com/mouson/20251212-ai-shi-dai-de-legacy-code-ying-jiu-shu) Apache 1.3 & php 4.x -> Nginx & php 8.2 (分五階段完成) 有辦法一次到位嗎 如果再走一次 ,AI時代會怎麼走? Legacy 怎麼變 Legacy? - 技術債: - 為了追求速度而做出的權衡,長期累積下來的利息(為求快速而走捷徑) - 缺乏持續的組織及整理(老闆常說能動就好...) - 能不能欠技術債?可以,但要可以還的起利息 - 需求變更 - 並非開發者的錯,而是環境必然的改變 - 產品的需求改變 - 環境變化 (e.g. CPU原本慢慢的很好,在快的CPU就壞了、或沒預料到使用者數量快速增長) - 外部依賴更新 - 一個可參考的重構框架 - 成功的重構 像蓋一棟建築 需要規劃執行與維護 - 勘查與量測 - 版本控制與數據更新 - 程式碼的覆蓋率 (寫好UT) - 原始碼靜態分析(確定有沒有deprcated code、弱點掃描) - CI持續整合 CD持續部署 ## 我們的實作與AI時代的勘查與量測 重新建立版本控制 建立內部issue tracking system 建立研發團隊 工作流程 AI世代 版本控制是基本需求 第二點沒記到 建立單元測試、整合測試、E2E =>先從核心重要的開始 [Refactoring at Scale](https://www.tenlong.com.tw/products/9789865027780) [sonarqube](https://www.sonarsource.com/products/sonarqube/) --- #### 聊天室 古老到沒機會碰到XDD ~~至少有composer~~ > 我的印象是5.2末版就有支援 但是好像並沒有XD > 主要是 namespace 的支援至少超過 5.3 之後才能相對的支援,真的完整支援,大概要 PHP 7.0 之後的版本 PHP 才真正的脫胎換骨。 跟爬樓梯一樣 一次跳五六階沒摔斷腿就不錯了XDDD >尤其年紀大了 能管理好的技術債就還好 >給別人還(被打) >同事還 在舊系統工作會照順序跑 新系統就變成順序會跳XD 最近的AI工具都只先支援github啊!!!!!! >claude code on web的gitlab支援啊~~~~ > 用cli的話沒差吧?
