[英]Is there a simple way to "git describe" a remote repository?
I want to execute the following command on a remote server: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-
The problem is I don't know what $tag
is.问题是我不知道
$tag
是什么。 It should be the output of git describe --abbrev=0
on an up-to-date clone, but I don't know how to get that information without making a local clone of the repository.它应该是
git describe --abbrev=0
在最新克隆上的输出,但我不知道如何在不制作存储库的本地克隆的情况下获取该信息。 Is it possible to do this without making a local clone?是否可以在不制作本地克隆的情况下执行此操作?
#!/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
}
Sample output样本输出
$ git-describe-remote.awk https://github.com/stedolan/jq
jq-1.4-148-g89791a0
The only way you could start parsing for your tag, without adding too much to your local disk, would be:您可以开始解析标签而不向本地磁盘添加太多内容的唯一方法是:
git fetch --dry-run
git fetch --dry-run
That will load the pack files of the remote repo, though.不过,这将加载远程仓库的包文件。
I don't think you can just query this information without downloading something .我不认为你可以只查询这些信息而不下载一些东西。
I have done it for a gitolite repo for instance:例如,我为 gitolite 存储库完成了此操作:
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

--- could be the tag you need
As mentioned above, the only traces are the pack files, so at least you can easily clean them once you have your information:如上所述,唯一的痕迹是包文件,因此至少您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/
