从svn转到git时保留所有历史记录

从svn转到git时,是否可以保留所有历史记录? 我发现 svn copy 之前的历史记录丢失了。

我有以下svn存储库:

  • PROJECT1 /中继线/ A
  • 项目2 /中继/ DIR / B
  • 项目3 /中继线
    • A - 从project1
    • 复制
    • dir / B - 从project2
    • 复制

如果我git svn clone project3,则project1和project2中没有A和B的历史记录。

以下是问题的演示:

> svn co https://localhost/svn/test
> cd test
> mkdir -p project1/trunk project1/branches project1/tags
> mkdir -p project2/trunk/dir project2/branches project2/tags
> mkdir -p project3/trunk project3/branches project3/tags
> touch project1/trunk/A project2/trunk/dir/B
> svn add project1 project2 project3
> svn ci -m 'initial commit'
> svn copy project1/trunk/A project3/trunk/
> svn copy project2/trunk/dir project3/trunk/
> svn ci -m 'project restructure'

每次运行 svn log 都会显示两个版本:

> svn log project3/trunk/A 
 ------------------------------------------------------------------------
 r2 | tanderson | 2015-04-16 19:37:33 +1000 (Thu, 16 Apr 2015) | 1 line

 project restructure
 ------------------------------------------------------------------------
 r1 | tanderson | 2015-04-16 19:37:32 +1000 (Thu, 16 Apr 2015) | 1 line

 initial commit
 ------------------------------------------------------------------------
> svn log project3/trunk/dir/B 
 ------------------------------------------------------------------------
 r2 | tanderson | 2015-04-16 19:37:33 +1000 (Thu, 16 Apr 2015) | 1 line

 project restructure
 ------------------------------------------------------------------------
 r1 | tanderson | 2015-04-16 19:37:32 +1000 (Thu, 16 Apr 2015) | 1 line

 initial commit
 ------------------------------------------------------------------------

现在克隆:

> git svn clone --stdlayout --follow-parent https://localhost/svn/test/project3 gittest
  Using higher level of URL: https://localhost/svn/test/project3 => https://localhost/svn/test
  r1 = 1bc0768d6d823b49305978d227df6834d2787fdc (refs/remotes/origin/trunk)
       A       A
       A       dir/B
  r2 = c71c15ec116a7ada952d8457d50902c970616ef5 (refs/remotes/origin/trunk)
  Checked out HEAD:
      https://localhost/svn/test/project3/trunk r2

我希望看到A和B的两个版本,但在这两种情况下只显示最终版本。 E.g。

> cd gittest
> git log --follow A
   commit c71c15ec116a7ada952d8457d50902c970616ef5

    project restructure

    git-svn-id: https://localhost/svn/test/project3/trunk@2 897fde24-c897-6841-ad7f-93f2e7295302

是的,它可以。有用于此目的的工具。

一个常见工具是https://github.com/nirvdrum/svn2git。它将完整的svn历史翻译为git。

在上面的简单测试存储库中,svn-all-fast-export可以正常工作。

它是用C ++编写的,并没有二进制文件。我能够使用cygwin构建它。

要隐藏上面的示例svn存储库:

  1. 在本地复制svn存储库(使用svnadmin hotcopy或svnsync)
  2. 根据https://git-scm.com/book/en/v2/Git-and-Other-Systems-Migrating-to-Git
  3. 创建作者文件users.txt
  4. 创建一个规则文件rules.txt来指示svn-fast-all-export如何处理存储库路径:

    create repository testnew
    end repository
    
    match /project1/trunk/
        repository testnew
        branch project1
    end match
    
    match /project2/trunk/
        repository testnew
        branch project2
    end match
    
    match /project3/trunk/
        repository testnew
        branch master
    end match
    
  5. 执行命令

    svn-all-fast-export --identity-map=users.txt --rules=rules.txt --stats /path/to/repo/test.svn
    
  6. 这将在当前目录中创建一个git存储库 testnew git log 命令显示A和B的两个版本。例如:

    > git log A
