使用pygit2从远程拉出的步骤 [英] Steps for pulling from remote using pygit2

问题描述

使用pygit2库时，一个简单的repo.fetch()会获取所有差异. 答案此处描述了步骤viz
1. Remote.fetch()
2. Repository.create_reference()或Reference.target=
3. Repository.checkout_head()

我不确定第二步到底发生了什么以及需要传递什么参数. r.repo.create_reference: (self, name, target, force=False)

创建一个指向对象或另一个对象的新引用名称"
参考.

根据目标参数的类型和值，此方法尝试
猜测它是直接引用还是符号引用.

关键字参数:

力
如果True引用将被覆盖，否则(默认)是一个
引发异常.

示例::

repo.create_reference('refs/heads/foo'，repo.head.target)
repo.create_reference('refs/tags/foo'，'refs/heads/master')
repo.create_reference('refs/tags/foo'，'bbb78a9cec580')

第二步中发生的事情以及Reference.target=的含义 它应该指向哪里? 以及所有这些如何使用Remote.fetch()动作?

解决方案

refs/heads/master":这是一个简单的文件，带有引用，必须包含该引用，以便该分支指向(引用)另一个分支SHA1.

While using the pygit2 library a simple repo.fetch() fetches all the diffs. The answer here describes the steps viz
1. Remote.fetch()
2. Repository.create_reference() or Reference.target=
3. Repository.checkout_head()

I am not sure about what is happening under the hood in second step and what parameters need to be passed. r.repo.create_reference: (self, name, target, force=False)

Create a new reference "name" which points to an object or to another
reference.

Based on the type and value of the target parameter, this method tries
to guess whether it is a direct or a symbolic reference.

Keyword arguments:

force
If True references will be overridden, otherwise (the default) an
exception is raised.

Examples::

repo.create_reference('refs/heads/foo', repo.head.target)
repo.create_reference('refs/tags/foo', 'refs/heads/master')
repo.create_reference('refs/tags/foo', 'bbb78a9cec580')

What is happening in the second step and what is meant by Reference.target= Where should it point to? And how does all this use the Remote.fetch() action?

解决方案

The create_reference method changes the target in order for said target to contains (reference) the name.

Here, after a fetch, you would want to set the reference of the local branch (you want to checkout) to the right remote tracking branch (you just fetched):

repo.create_reference('refs/remotes/origin/master', 'refs/heads/master')

You can look up the file "refs/heads/master" in your .git folder: it is a simple file with the reference it has to contain in order for that branch to point to (reference) another branch SHA1.
