通过HTTP转储基于Git的远程SVN存储库时出错

Question

我试图克隆/镜像GitHub仓库时遇到了几个错误.我试过在本地通过HTTPS或服务器到服务器这样做(所以我可以将它热回复到我们的SVN服务器仓库).我正在使用的BASH脚本应该转储repo失败并出现以下错误:

$ svnsync init file:/// home/jdaniel/www/clone/rest https://github.com/ehime/Restful-MVC-Prototype
svnsync:E125005:错误或意外的属性值
svnsync:E125003:虚假日期

$ svnsync同步文件:/// home/jdaniel/www/clone/rest https://github.com/ehime/Restful-MVC-Prototype
svnsync:E200007:请求的报告未知.

我也试过使用snvrdump但得到一个类似奇怪的问题:

$ svnrdump dump https://github.com/ehime/CLI-Parser

svnrdump: E200007: The requested report is unknown.

这以相同的Requested report is unknown错误结束.

到目前为止我测试的所有GitHub repos(4-5)都会报告未知错误.请帮忙.

根据 Simons 的要求，这是我最终编写的用于将 Subversion 移至 GH 的脚本

\n

不管怎样，git-svn 很好地支持了这一点，只是与通常的 git svn 克隆略有不同。

\n

我们使用稍微不同的而不是标准的项目/主干|分支|标签，parent/trunk|branches|tags/project因此您\xe2\x80\x99会看到我指定了 -T/-t/-b标志。

\n

git svn init\n

\n

这是我从现有的本地 git 存储库中所做的：

\n

# Create the project directory in subversion\n$ /usr/bin/svn mkdir\n  https://example.com/svn/parent/trunk/project\n  -m "Make project directory."\nCommitted revision 200.\n\n# Initialize git-svn, doesn't fetch anything yet\n$ git svn init https://example.com/svn/\n  -T parent/trunk/project\n  -t parent/tags/project\n  -b parent/branches/project\n  --prefix=svn/\n\n# Set authors so we get prettier authors\n$ git config svn.authorsfile ../authors\n\n# Now pull down the svn commits\n$ git svn fetch\nW: Ignoring error from SVN, ...\nW: Do not be alarmed at the above message git-svn ...\nThis may take a while on large repositories\nr200 = (guid) (refs/remotes/svn/trunk)\n\n# We should now see our svn trunk setup under our svn remote\n$ git branch -av\n* master            c3a7161 The latest git commit.\n  remotes/svn/trunk 3b7fed6 Make project directory.\n\n# Now we want to take all of our local commits and \n# rebase them on top of the new svn/trunk\n$ git rebase svn/trunk\nFirst, rewinding head to replay your work on top of it...\nApplying: First git commit\nApplying: The latest git commit\n\n# Now we should see our local commits applied\n# on top of svn/trunk\n$ git lg\n* 52b7977 (HEAD, master) The latest git commit\n* a34e162 First git commit\n* 3b7fed6 (svn/trunk) Make project directory.\n\n# Everything is cool, push it back to svn\n$ git svn dcommit\nCommitting to https://example.com/svn/parent/trunk/project\n...\n\n\xe2\x80\x93prefix=svn\n

\n

我最近特别喜欢的一个标志git svn clone是，您也可以将其与 一起使用--prefix=svn/。

\n

这将为远程 Subversion 分支、标签和主干的所有跟踪分支添加 svn/ 前缀，使其看起来非常像常规 git 远程使用的常用 origin/ 习惯用法。

\n

由于跟踪分支具有前缀，您还可以将它们用作本地分支名称，例如：

\n

# Name your copy of svn/trunk "trunk" instead of "master"\n$ git checkout -b trunk master\nSwitched to a new branch 'trunk'\n\n$ git branch -d master\nDeleted branch master (was 33c3136).\n\n$ git branch -av\n* trunk             33c3136 Latest svn commit\n* remotes/svn/trunk 33c3136 Latest svn commit\n

\n

然后，如果您想跟踪其他分支：

\n

$ git checkout -b featurea svn/featurea\n
