Question

我想在远程服务器上执行以下命令：

git archive --prefix="$tag/" --remote="ssh://$gitserver/var/git/$repo" "$tag" | tar -xvf-

问题是我不知道$tag是什么。它应该是最新克隆上git describe --abbrev=0的输出，但我不知道如何在不进行存储库的本地克隆的情况下获取该信息。是否可以在不进行本地克隆的情况下执行此操作？

Answer 1

#!/usr/bin/awk -f
BEGIN {
  FS = "[ /^]+"
  while ("git ls-remote " ARGV[1] "| sort -Vk2" | getline) {
    if (!sha)
      sha = substr($0, 1, 7)
    tag = $3
  }
  while ("curl -s " ARGV[1] "/releases/tag/" tag | getline)
    if ($3 ~ "commits")
      com = $2
  printf com ? "%s-%s-g%s\n" : "%s\n", tag, com, sha
}

示例输出

$ git-describe-remote.awk https://github.com/stedolan/jq

Answer 2

您可以开始解析代码而不将太多添加到本地磁盘的唯一方法是：

制作一个空的回购
添加远程仓库的远程地址
尝试git fetch --dry-run

但是，这将加载远程仓库的包文件我认为您不能在不下载某事的情况下查询此信息。

我为gitolite repo做过这样的事情，例如：

VonC@NETVONC /c/prog/git
$ git init g2
Initialized empty Git repository in c:/prog/git/g2/.git/

VonC@NETVONC /c/prog/git
$ cd g2

VonC@NETVONC /c/prog/git/g2 (master)
$ git remote add origin https://github.com/sitaramc/gitolite.git

VonC@NETVONC /c/prog/git/g2 (master)
$ git fetch --dry-run

如上所述，唯一的痕迹是包文件，所以至少你可以在获得信息后轻松清理它们：

VonC@NETVONC /c/prog/git/g2 (master)
$ l .git/objects/pack/
total 1000
drwxr-xr-x    4 VonC     Administ        0 Nov  8 19:45 ..

是否有一种简单的方法来“git describe”一个远程存储库？
