使用strace查九州娛樂888 找Emacs啟動壅閉的緣故原由

由

之前就以為我的 Emacs 啟動好慢，查望啟動日記會發明啟動到一般的時辰會有一個比較永劫間的卡頓。 之前一向沒有理會它，本日花了點時間索求了一下，發明禍首罪魁竟然是 exec-path-from-shell 這個包。
現將索求的進程記載以下： 因為使用了 spacemacs 的設置，設置上比較龐大，不太想經由過程試驗縮減設置的方式來試探出成績之處。剛好近來在進修使用 strace 對象，是以決定使用 strace 來望望 Emacs 到底卡在那里。

strace emacs –fg-daemon

輸入的內容分外多，這里只截取卡頓前的部門內容
