获取远程遥控器和远程远程分支

发布于 2024-10-17 19:03:18 字数 566 浏览 7 评论 0原文

我想获取远程存储库的远程分支。

因此，例如，在这种情况下 —

$ cd alpha
$ git remote
beta
$ git branch -a
master
remotes/alpha/master
$ cd ../beta
$ git remote
gamma
$ git branch -a
master
remotes/gamma/slave

— 我想通过 gamma 的 slave 分支将其提取到 alpha 存储库中代码>测试版。这可能会添加 gamma 作为 alpha 的远程，并使用 gamma/slave 作为新分支的 refspec。我不一定想创建本地跟踪分支。与示例不同，我也不一定具有对 beta 或 gamma 的文件系统访问权限。

这种事情可以通过 $ git clone --mirror 来完成，但是有没有办法在已经存在的存储库中做到这一点？

原文

I'd like to fetch the remote branches of a remote repository.

So, for example, in this situation —

$ cd alpha
$ git remote
beta
$ git branch -a
master
remotes/alpha/master
$ cd ../beta
$ git remote
gamma
$ git branch -a
master
remotes/gamma/slave

— I'd like to fetch gamma's slave branch into the alpha repository by going through beta. This would presumably add gamma as a remote of alpha and use gamma/slave for the new branch's refspec. I don't necessarily want to create a local tracking branch. I also don't necessarily have filesystem access to beta or gamma, unlike in the example.

This sort of thing can be done with $ git clone --mirror, but is there a way to do it in an already-existing repo?

看起来设置一个非默认的 refspec 会让我半途而废。

例如，考虑以下设置：

初始化gamma

$ (mkdir gamma; cd gamma; git init; touch README; git add README;
   git commit -m '初始化从站。'; git 分支 -m 从属；回声）
在 /tmp/test-git/gamma/.git/ 中初始化空 Git 存储库
[master (root-commit) 0cebd50] 已初始化从站。
 0 个文件已更改、0 个插入(+)、0 个删除(-)
 创建模式 100644 自述文件

初始化 beta 并将 gamma 添加为遥控器：

$ (mkdir beta; cd beta; git init; touch README; git add README;
   git commit -m '初始化主控。';
   git 远程添加伽玛../伽玛; git 获取伽玛
   回声; echo "在仓库 $(basename $PWD) 中："; git分支-a；回声）
在 /tmp/test-git/beta/.git/ 中初始化空 Git 存储库
[master (root-commit) f6512e1] 已初始化 master。
 0 个文件已更改、0 个插入(+)、0 个删除(-)
 创建模式 100644 自述文件
警告：没有共同提交
远程：计数对象：3，完成。
远程：总共 3 个（增量 0），重用 0 个（增量 0）
拆开物体：100% (3/3)，完成。
来自../伽玛
 * [新分支]奴隶->伽玛/从属

在回购测试版中：
* 掌握
  遥控器/伽玛/从属

克隆 beta 以制作 alpha< /代码>：

$ git 克隆 beta alpha
在 /tmp/test-git/alpha/.git/ 中初始化空 Git 存储库
$ cd 阿尔法; git分支-a
* 掌握
  遥控器/原点/HEAD ->起源/主人
  遥控器/原点/主控

现在变得激烈：

# Avoid errors from pulling into active branch.
$ git checkout origin/master  | head -3  # intentionally acquire severed HEAD
Note: checking out 'origin/master'.

You are in 'detached HEAD' state. You can look around, make experimental
$ git fetch origin '+refs/*:refs/*'      # pour steroids into open esophagus
From /tmp/test-git/beta
 * [new branch]      gamma/slave -> gamma/slave
$ git branch -a
* (no branch)
  master
  remotes/gamma/slave
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
$ git remote
origin

所以执行 `$ git fetch '+refs/:refs/< /em>' 将拉入分支本身，但不会更新构成其所属远程的配置项。

有趣的是，为无远程分支设置跟踪分支将导致它开始跟踪自己的存储库：

$ git branch --track slave gamma/slave 
Branch slave set up to track local ref refs/remotes/gamma/slave.
$ git config -l | grep '^remote\|^branch'
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
remote.origin.url=/tmp/test-git/beta
branch.master.remote=origin
branch.master.merge=refs/heads/master
branch.slave.remote=.
branch.slave.merge=refs/remotes/gamma/slave

我认为这实际上不起作用。

$ git checkout slave
Switched to branch 'slave'
$ git fetch
From .
 * remote branch     gamma/slave -> FETCH_HEAD
$ git fetch
From .
 * remote branch     gamma/slave -> FETCH_HEAD

It looks like setting a non-default refspec will get me partway there.

For example, consider this setup:

Initialize gamma

$ (mkdir gamma; cd gamma; git init; touch README; git add README;
   git commit -m 'Initialized slave.'; git branch -m slave; echo)
Initialized empty Git repository in /tmp/test-git/gamma/.git/
[master (root-commit) 0cebd50] Initialized slave.
 0 files changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 README

Initialize beta and add gamma as a remote:

$ (mkdir beta; cd beta; git init; touch README; git add README;
   git commit -m 'Initialized master.';
   git remote add gamma ../gamma; git fetch gamma
   echo; echo "In repo $(basename $PWD):"; git branch -a; echo)
Initialized empty Git repository in /tmp/test-git/beta/.git/
[master (root-commit) f6512e1] Initialized master.
 0 files changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 README
warning: no common commits
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
From ../gamma
 * [new branch]      slave      -> gamma/slave

In repo beta:
* master
  remotes/gamma/slave

clone beta to make alpha:

$ git clone beta alpha
Initialized empty Git repository in /tmp/test-git/alpha/.git/
$ cd alpha; git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

Now get fierce:

# Avoid errors from pulling into active branch.
$ git checkout origin/master  | head -3  # intentionally acquire severed HEAD
Note: checking out 'origin/master'.

You are in 'detached HEAD' state. You can look around, make experimental
$ git fetch origin '+refs/*:refs/*'      # pour steroids into open esophagus
From /tmp/test-git/beta
 * [new branch]      gamma/slave -> gamma/slave
$ git branch -a
* (no branch)
  master
  remotes/gamma/slave
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
$ git remote
origin

So doing a `$ git fetch '+refs/:refs/' will pull in the branch itself, but will not update the configuration items that constitute the remote that it belongs to.

Interestingly, setting a tracking branch for the remoteless remote branch will cause it to start tracking its own repo:

$ git branch --track slave gamma/slave 
Branch slave set up to track local ref refs/remotes/gamma/slave.
$ git config -l | grep '^remote\|^branch'
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
remote.origin.url=/tmp/test-git/beta
branch.master.remote=origin
branch.master.merge=refs/heads/master
branch.slave.remote=.
branch.slave.merge=refs/remotes/gamma/slave

I think this doesn't really work.

$ git checkout slave
Switched to branch 'slave'
$ git fetch
From .
 * remote branch     gamma/slave -> FETCH_HEAD
$ git fetch
From .
 * remote branch     gamma/slave -> FETCH_HEAD
