git过滤器分支和git子树之间的区别？ [英] Difference between git filter branch and git subtree?
问题描述
有人能告诉我b / w git子树和git filter-branch的区别吗？
我会在原始问题中使用同样的例子：
git subtree split --prefix = some_subdir -b some_branch
git filter-branch --subdirectory-filter some_subdir some_branch
是， git subtree （一个contrib外壳程序）可用于分割回购库，如通过。 com / stucampbellrel =nofollow noreferrer> Stu Campbell 。
您需要删除您在分割文件夹中复制的代码：
git subtree split --prefix = path / to / code -b split
git push〜/ shared / s plit：master
git rm -r path / to / code
git commit -am删除拆分代码。
与 git filter-branch （原生Git命令），它重写回购历史记录，实际上会影响特定子目录的内容。
含义：在 git rm c $ c> filter-branch 已经运行。
git filter-branch 不会像 git subtree split 确实：删除（过滤掉）与特定条件不匹配的所有内容（这里是子文件夹路径）
Was searching throw SO for an answer to this. Came across this older thread which didn't seem to give any answers. Retriggering this thread hoping someone may know!
Can someone tell me the difference b/w git subtree and git filter-branch? I'll use the same example in the original question for this:
git subtree split --prefix=some_subdir -b some_branch
git filter-branch --subdirectory-filter some_subdir some_branch
Yes, git subtree (a contrib shell) can be used to split repos, as described in "Using Git subtrees for repository separation" by Stu Campbell.
You need to remove the code that you have duplicated in your split folder though:
git subtree split --prefix=path/to/code -b split
git push ~/shared/ split:master
git rm -r path/to/code
git commit -am "Remove split code."
That differs from git filter-branch (a native Git command) which rewrites the repo history picking up only those commits that actually affect the content of a specific subdirectory.
Meaning: there is no code to git rm once the filter-branch has been run.
git filter-branch does not duplicate commits like git subtree split does: it deletes ("filters out") everything that does not match a certain criteria (here a subfolder path)
