將從舊分支添加的代碼行添加到最新版本

Question

我有一個由Stephan Ritcher更改的舊版本repo（renderdoc）（v 0.27）。然而它有很多bug，原來的作者Baldurk已經在最新版本中修正了0.33。問題是，如何從v 0.27獲取修補程序或更改並將其添加到v 0.33，或者如何更容易地從v 0.33獲取bug修復並將其添加到Stephan的分支？

此外，我怎樣才能以交互方式選擇所有Stephan的修補程序？

Answer 1

對於舊版本v0.27中的/d/experiment/renderdoc，您可以將其添加爲v0.33中的遠程/d/latest_renderdoc/renderdoc。然後，您可以將更改從v0.27更改爲v0.33。如下具體步驟：

git remote add old /d/experiment/renderdoc 
git fetch old 
git rebase --onto master <commit id on v0.27 before start to rebase) <commit if on v0.27 of the end to rebase> 
git checkout -b temp 
git checkout master 
git merge temp 

比如，如果你想在提交變基從7fff78c1a341e15e143a6007837414265cf124ee到c67e3e7b7a221780ff904c516e9861826939e511到v0.33主分支，你應該使用git rebase --onto master 5b60cf6 c67e3e7。

由於提交給主版本的提交併不存在於您的源中，並且在您將這些提交重新署定爲主版本之後，這些都不是分支點。所以你需要在完成rebase之後創建一個分支來指向提交，然後快速轉發master分支來指向它（作爲上面的最後3個命令）。
