在GUI中單擊存盤庫/壓縮資料庫時執行的git命令到底是什么($gitgui)-有解無憂

我想知道在 GUI ($git gui) 中單擊存盤庫/壓縮資料庫時執行的 git 命令究竟是什么？有人可以撰寫此選單選項中執行的內容嗎？在 GUI 中單擊存盤庫/壓縮資料庫時執行的 git 命令到底是什么 ($git gui)

我檢查了來源，這是它的作用：

${NS}::button $w.buttons.gc -text [mc "Compress Database"] \
  34                 -default normal \
  35                 -command "destroy $w;do_gc"

// < snip >

proc do_gc {} {
  72         set w [console::new {gc} [mc "Compressing the object database"]]
  73         console::chain $w {
  74                 {exec git pack-refs --prune}
  75                 {exec git reflog expire --all}
  76                 {exec git repack -a -d -l}
  77                 {exec git rerere gc}

所以有趣的部分（git 命令）是：

git pack-refs --prune
git reflog expire --all
git repack -a -d -l
git rerere gc

檔案在這里：
git pack-refs
git reflog
git repack
git rerere

不知道是否有一種方法來跟蹤命令，因為它們運行，您可以嘗試激活之一git的跟蹤ENV變數啟動時git gui：

GIT_TRACE=1 git gui

但是，代碼實際上是可以訪問的：查看'repo.xml中的git-gui/git-gui.sh檔案git。

搜索Compress database指向該檔案的線索，
搜索do_gc到該功能：

proc do_gc {} {
    set w [console::new {gc} [mc "Compressing the object database"]]
    console::chain $w {
        {exec git pack-refs --prune}
        {exec git reflog expire --all}
        {exec git repack -a -d -l}
        {exec git rerere gc}
    }
}

strace -qqv -f -e execve -e signal=\!all git gui

將向您展示確切的內容git gui及其所有子項 exec，一點點清理（在 vim 中:set nowrap|g/execve(/.,/ = 0$/j）讓我看著
