您可以使用 Subversion 进行部分结帐吗？

发布于 2024-07-04 03:26:58 字数 95 浏览 10 评论 0原文

如果我在 trunk/ 下有 20 个目录，每个目录中有很多文件，并且只需要其中的 3 个目录，是否可以仅使用 trunk 下的这 3 个目录进行 Subversion 签出？

事实上，由于对我的帖子的评论，它看起来像稀疏目录是正确的选择。我相信以下应该做到这一点：

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，--深度立即数而不是empty检查trunk/proj中的文件和目录，而不带其内容。这样您就可以看到存储库中存在哪些目录。

正如 @zigdon 的回答中提到的，您还可以进行非递归结帐。这是一种较旧且不太灵活的方法来实现类似的效果：

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

Indeed, thanks to the comments to my post here, it looks like sparse directories are the way to go. I believe the following should do it:

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

Alternatively, --depth immediates instead of empty checks out files and directories in trunk/proj without their contents. That way you can see which directories exist in the repository.

As mentioned in @zigdon's answer, you can also do a non-recursive checkout. This is an older and less flexible way to achieve a similar effect:

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

Subversion 1.5 引入了稀疏结帐，这可能对您有用。来自文档：

...稀疏目录（或浅层检出）...允许您更浅地轻松检出工作副本或工作副本的一部分比完全递归，可以在以后自由地引入以前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结账。

#!/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

或者对 /trunk 进行非递归签出，然后对您需要的 3 个目录进行手动更新。

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 命令支持多个路径。

更新根本地副本不会更改已修改文件夹的深度。

要将文件夹恢复为重复签出，您可以再次使用带有无穷大参数的 --set-depth 。

svn update --set-depth=infinity www

If you already have the full local copy, you can remove unwanted sub folders by using --set-depth command.

svn update --set-depth=exclude www

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

The set-depth command support multipile paths.

Updating the root local copy will not change the depth of the modified folder.

To restore the folder to being recusively checkingout, you could use --set-depth again with infinity param.

svn update --set-depth=infinity www

有点。正如鲍比所说：

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

将获得文件夹，但从颠覆的角度来看，您将获得单独的文件夹。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。

Sort of. As Bobby says:

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

will get the folders, but you will get separate folders from a subversion perspective. You will have to go separate commits and updates on each subfolder.

I don't believe you can checkout a partial tree and then work with the partial tree as a single entity.
