Git子树标记

Question

我想使用子树合并将一个远程项目拉到我自己的git树中的一个目录中。我按照这里的说明操作：using subtree merge

但我不确定如何签出标签。我想这是一个常见的请求--你想引入一个外部项目，但是得到一个安全的标记版本的源代码。子树合并解决方案工作得很好，但我不确定如何获得我想要的标签？我喜欢git，但有时它会让我头疼……

Answer 1

当您输入git tag时，您将获得存储库中所有标签的列表。远程标签也在这里显示，我不知道它们是否会冲突(没有检查)，以及如何检查哪些标签被导入到您的存储库。

但我检查的是，当你添加remote时，它从其他项目获取，你会看到导入了哪些标签。然后，您可以与该标记合并，例如：

git merge -s ours --no-commit v0.1.2 # instead of: Bproject/master (2)
git read-tree --prefix=dir-B/ -u v0.1.2 # instead of: Bproject/master (3)

它应该是有效的。

希望这会有一点帮助，但我并不像我希望的那样使用git :-)

Answer 2

GitHub采用了kernel.org的HowTo：http://help.github.com/subtree-merge/

Answer 3

我在Github上做了一个名为的示例项目，如下所示：

我在下面的示例中使用了curl、jq、cut和tail命令，因此在运行示例之前需要使用它们。

对于第一个，找到项目的最后两个标记：

me@ubuntu: ~ $ curl -s https://api.github.com/repos/hesco/hesco-weave/git/refs/tags | jq -r ".[].ref" | cut -d "/" -f 3
v0.1
v0.2
v0.3
v0.4
v0.5
v0.6
v0.7
v0.8
v0.8.6
v0.8.7

me@ubuntu: ~ $ curl -s https://api.github.com/repos/hesco/hesco-weave/git/refs/tags | jq -r ".[].ref" | cut -d "/" -f 3 | tail -n 3
v0.8.6
v0.8.7

或者，如果你有一个项目的签出版本：

me@ubuntu: ~/github/hesco-weave (master) $ git remote -v
origin  https://github.com/hesco/hesco-weave.git (fetch)
origin  https://github.com/hesco/hesco-weave.git (push)
me@ubuntu: ~/github/hesco-weave (master) $ git tag -l
v0.1
v0.2
v0.3
v0.4
v0.5
v0.6
v0.7
v0.8
v0.8.6
v0.8.7

me@ubuntu: ~/github/hesco-weave (master) $ git tag -l | tail -n 2
v0.8.6
v0.8.7

参考文献如下：

me@linux: ~ $ git ls-remote | tail -n 2
be74d8368acd4815b6863daded46a232944e0d84  refs/tags/v0.8.6
9181306caa304b4cf8b3764b1446c0c4006833d8  refs/tags/v0.8.7

对于第二个，将创建一个git存储库：

me@linux: ~  $ mkdir -p ~/test
me@linux: ~  $ cd ~/test
me@linux: ~/test  $ git init
Initialized empty Git repository in ~/test/.git/
me@linux: ~/test  $ touch README.md
me@linux: ~/test  $ git add .
me@linux: ~/test  $ git commit -m "README.md added"
[master (root-commit) b1ac90e] README.md added
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 README.md
me@linux: ~/test (master) $ git log

Author: Me <me@linux.me>
Date:   Wed Jun 14 13:02:05 2017 +0200

README.md added

对于第三个，Github存储库的v0.8.6标签将作为子树添加到创建的存储库中：

me@linux: ~/test (master) $ git subtree add --squash --prefix=weave https://github.com/hesco/hesco-weave.git v0.8.6

git fetch https://github.com/hesco/hesco-weave.git v0.8.6

最后是，带有较新标记v0.8.7的编织子树与git subtree pull合并

me@linux: ~/test (master) $ git subtree pull --squash --prefix=weave https://github.com/hesco/hesco-weave.git v0.8.7
