你能用Subversion做部分结账吗?

如果我在trunk下有20个目录,每个目录中有很多文件,只需要3个目录,是否可以在trunk下只有3个目录进行Subversion结账?

的确,感谢我在这里发表的评论,看起来sparse directories是可行的方式。我相信以下内容应该这样做:

svn checkout --depth empty http://svnserver/trunk/proj
svn update --set-depth infinity proj/foo
svn update --set-depth infinity proj/bar
svn update --set-depth infinity proj/baz

或者,--depth immediates代替empty检查trunk/proj中没有内容的文件和目录。这样您就可以看到存储库中存在哪些目录。


正如@ zigdon的回答中所提到的,你也可以进行非递归结账。这是一种较老且不太灵活的方式来实现类似的效果:

svn checkout --non-recursive http://svnserver/trunk/proj
svn update trunk/foo
svn update trunk/bar
svn update trunk/baz

Subversion 1.5引入了稀疏检查,这可能是您可能会觉得有用的东西。来自documentation

  

... 稀疏目录(或浅签出)...允许您轻松查看工作副本或工作副本的一部分 - 更浅比完全递归,可以自由地在以后引入先前被忽略的文件和子目录。

我编写了一个脚本来自动执行复杂的稀疏检出。

#!/usr/bin/env python

'''
This script makes a sparse checkout of an SVN tree in the current working directory.

Given a list of paths in an SVN repository, it will:
1. Checkout the common root directory
2. Update with depth=empty for intermediate directories
3. Update with depth=infinity for the leaf directories

答案 3 :(得分:5)

或者对/ trunk进行非递归检查,然后只需对您需要的3个目录进行手动更新。

答案 4 :(得分:0)

如果您已经拥有完整的本地副本,则可以使用--set-depth命令删除不需要的子文件夹。

svn update --set-depth=exclude www

请参阅:http://blogs.collab.net/subversion/sparse-directories-now-with-exclusion

set-depth命令支持多路径。

更新根本地副本不会更改修改后的文件夹的深度。

要将文件夹恢复为可退回签出,可以再次将--set-depth与无穷大参数一起使用。

svn update --set-depth=infinity www

答案 5 :(得分:-1)

排序。正如鲍比所说:

svn co file:///.../trunk/foo file:///.../trunk/bar file:///.../trunk/hum

将获取文件夹,但您将从subversion角度获取单独的文件夹。您必须对每个子文件夹进行单独的提交和更新。

我不相信您可以签出部分树,然后将部分树作为单个实体使用。

答案 6 :(得分:-10)

没有任何特别有用的方式,没有。你可以查看子树(如Bobby Jack的建议),但是你失去了以原子方式更新/提交它们的能力;要做到这一点,他们需要被置于他们共同的父母之下,一旦你检查了共同的父母,你就会下载该父母的一切。非递归不是一个好的选择,因为您希望更新和提交是递归的。
