无法读取root

Question

所以我使用SharpSVN(SharpSvn.1.7-x86 1.7008.2243)并且我一直遇到问题.每当我尝试使用SvnWorkingCopyClient位于驱动器根目录的repo时(例如说我有D:\驱动器,它本身就是一个repo)它会svn_dirent_is_absolute向我抛出一个错误.

事实上,我能找到的唯一没有关心的命令是 SvnClient.GetUriFromWorkingCopy(string)

关于我如何解决这个问题的任何想法(除了移动我的工作副本或链接文件系统)？我希望在代码中找到一种方法,或者替代解决这个限制(因为看起来SVN 1.7不再具有此限制).

这是一些代码？

private void fakeFunction(){
    var RootPath="d:\";
    using (var client = new SharpSvn.SvnClient())
    using(var workingClient = new SvnWorkingCopyClient())
    {
        SvnWorkingCopyVersion workingVersion = null;
        // Exception happens here
        if (workingClient.GetVersion(this.RootPath, out workingVersion))
        {
            CurrentRevision = workingVersion.End;
                // This will resolve just fine
            var targetUri = client.GetUriFromWorkingCopy(RootPath);
            var target = SvnTarget.FromUri(targetUri);
            SvnInfoEventArgs info = null;
            if (client.GetInfo(target, out info))
            {
                if (workingVersion.End != info.Revision)
                {
                    System.Collections.ObjectModel.Collection<SvnLogEventArgs> logEventArgs = null;
                    if (client.GetLog(targetUri, out logEventArgs))
                    {
                        var oldBack = Console.BackgroundColor;
                        var oldFor = Console.ForegroundColor;
                        Console.BackgroundColor = ConsoleColor.DarkMagenta;
                        Console.ForegroundColor = ConsoleColor.White;
                        foreach (var l in logEventArgs)
                        {
                            Console.WriteLine("[{0}-{1}]-{2}", l.Revision, l.Author, l.LogMessage);
                        }
                        Console.BackgroundColor = oldBack;
                        Console.ForegroundColor = oldFor;
                    }

                    System.Console.WriteLine("Repo not up to date.");
                }
            }
        }
    }
}

我也偶然发现了这个http://subversion.tigris.org/issues/show_bug.cgi?id=3535和http://subversion.tigris.org/ds/viewMessage.do?dsForumId=463&viewType=browseAll&dsMessageId=2456472

所以,既然这种情况发生了,那么这不应该是一个问题吗？

SharSVN 存在根路径问题，我们可以在邮件存档中读取到。不过，我们可以为您的场合做一些小技巧：

1. 下载完整包 Sharpsvn http://sharpsvn.open.collab.net/files/documents/180/5569/SSvnEx-1.7002.1998.zip
2. 将 svnversion.exe 复制到您的 bin 目录

3. 然后我们需要一个 hack 方法来获取 verison

       public static bool GetVersionHack(string appPath,string targetPath,out long version)
       { 
          // <param name="appPath">Path to svnversion.exe</param>
          // <param name="path">Target path</param>
          // <param name="version">Result version</param>
   
           Process p = new Process();               
   
           p.StartInfo.UseShellExecute = false;
           p.StartInfo.RedirectStandardOutput = true;
           p.StartInfo.FileName = appPath;
           p.StartInfo.Arguments = targetPath + " -n";
           p.Start();
   
           //read svnversion.exe result
           string output = p.StandardOutput.ReadToEnd();
           p.WaitForExit();
   
           output = output.Replace("M", "");
           output = output.Replace("S", "");
           output = output.Replace("P", "");
   
           //valid results
           //4123:4168     mixed revision working copy
           //4168M         modified working copy
           //4123S         switched working copy
           //4123P         partial working copy, from a sparse checkout
           //4123:4168MS   mixed revision, modified, switched working copy            
   
           return long.TryParse(output, out version);
       }
   

4. 并修改你的假方法完整源代码

当然，这是一项肮脏的工作，但它可能会有所帮助。请小心svnversion.exe 结果 GetVersionHack 不理想。
