SVN到Git转换后缺少标签 [英] Missing tags after SVN to Git conversion

问题描述

我正在尝试使用以下命令将Subversion存储库转换为Git存储库.

I'm trying to convert a Subversion repository to a Git repository using the following commands.:

git svn clone URL_TO_SVN/PROJECT --authors-file=users.txt -T trunk -b branches -t tags/release

与SVN标准布局唯一不同的是SVN标签存储在tags/release下.

The only thing that differs from the SVN standard layout is that the SVN tags stored under tags/release.

移动 SVN标签后，成为合适的Git 标签:

cp -Rf .git/refs/remotes/origin/tags/release/* .git/refs/tags/
rm -Rf .git/refs/remotes/origin/tags

我只有几个标签，但是现在并不是所有的SVN标签都是Git标签.

I only get a few tags, but not all SVN tags are now Git tags.

在SVN存储库中，标签的版本从0.1到0.35.2，但在Git存储库中，我仅包含标签0.33.10、0.34.0、0.34.1、0.34.2、0.35.0、0.35. 1，0.35.2.

In the SVN repo are tags from version 0.1 up to 0.35.2, but in the Git repo I only have the tags 0.33.10, 0.34.0, 0.34.1, 0.34.2, 0.35.0, 0.35.1, 0.35.2.

如何将所有SVN标签转换为Git标签?

How can I convert all SVN tags to Git tags?

推荐答案

我猜想您的存储库已打包，因此一些引用已经在打包文件中，因此您不能简单地在它们上使用cp或rm

I'd guess that your repo was packed and thus some references were in pack files already and thus you cannot simply use cp or rm on them.

但是，无论如何，对于一次性迁移git-svn来说，不是不是用于存储库或部分存储库转换的正确工具.如果要将Git用作现有SVN服务器的前端，这是一个很好的工具，但是对于一次性转换，您应该不使用git-svn，而svn2git则更适合这个用例.

But anyways, for a one-time migration git-svn is not the right tool for conversions of repositories or parts of repositories. It is a great tool if you want to use Git as frontend for an existing SVN server, but for one-time conversions you should not use git-svn, but svn2git which is much more suited for this use-case.

有很多称为svn2git的工具，可能最好的工具是来自 https://github.com/svn-all-fast-export/svn2git .我强烈建议使用该svn2git工具.这是我所知道的最好的，它在处理规则文件方面非常灵活.

There are plenty tools called svn2git, the probably best one is the KDE one from https://github.com/svn-all-fast-export/svn2git. I strongly recommend using that svn2git tool. It is the best I know available out there and it is very flexible in what you can do with its rules files.

您将能够轻松配置svn2git规则文件，以从当前SVN布局中生成所需的结果，包括可能存在的任何复杂历史记录，以及从一个SVN存储库中生成多个Git存储库，或组合使用不同的SVN干净地存储到一个Git存储库中.

You will be easily able to configure svn2gits rule file to produce the result you want from your current SVN layout, including any complex histories that might exist and including producing several Git repos out of one SVN repo or combining different SVN repos into one Git repo cleanly.

如果您不是100％知道存储库的历史记录，请从 http://blog.hartwork.org/?p=763 是将SVN储存库迁移到Git时研究其历史的绝佳工具.

If you are not 100% about the history of your repository, svneverever from http://blog.hartwork.org/?p=763 is a great tool to investigate the history of an SVN repository when migrating it to Git.

尽管git-svn较容易入门，但还有一些其他原因为什么除了灵活性之外，使用KDE svn2git代替git-svn更为优越:

Even though git-svn is easier to start with, here are some further reasons why using the KDE svn2git instead of git-svn is superior, besides its flexibility:

• 通过svn2git(如果使用了正确的历史记录)可以更好，更清晰地重建历史记录，对于具有分支和合并等更复杂历史记录的情况尤其如此.
• 标签是真实标签，不是Git中的分支
• 带有git-svn的标记包含一个额外的空提交，这也使它们不属于分支，因此普通的fetch不会得到它们，直到您将--tags赋予命令为止，因为默认情况下仅指向提取的分支也将被提取.带有正确的svn2git标签是它们所属的地方
• 如果您在SVN中更改了布局，则可以轻松地使用svn2git进行配置，而使用git-svn最终会丢失历史记录
• 使用svn2git，您还可以轻松地将一个SVN存储库拆分为多个Git存储库
• 或将同一SVN根目录中的多个SVN存储库轻松组合到一个Git存储库中
• 使用正确的svn2git进行的转换要比使用git-svn
的转换快万千倍

• the history is rebuilt much better and cleaner by svn2git (if the correct one is used), this is especially the case for more complex histories with branches and merges and so on
• the tags are real tags and not branches in Git
• with git-svn the tags contain an extra empty commit which also makes them not part of the branches, so a normal fetch will not get them until you give --tags to the command as by default only tags pointing to fetched branches are fetched also. With the proper svn2git tags are where they belong
• if you changed layout in SVN you can easily configure this with svn2git, with git-svn you will loose history eventually
• with svn2git you can also split one SVN repository into multiple Git repositories easily
• or combine multiple SVN repositories in the same SVN root into one Git repository easily
• the conversion is a gazillion times faster with the correct svn2git than with git-svn

您看到，git-svn较差而KDE svn2git较优的原因很多. :-)

You see, there are many reasons why git-svn is worse and the KDE svn2git is superior. :-)
