Can't read root

Question

So I'm using SharpSVN(SharpSvn.1.7-x86 1.7008.2243) and I keep running into a problem. Every time I try to use the SvnWorkingCopyClient on a repo that's at the root of a drive( for example say I have the D:\ drive, and it itself is a repo) it throws a svn_dirent_is_absolute error at me.

In fact the only command I could find that didn't care was SvnClient.GetUriFromWorkingCopy(string)

Any Ideas on how I could resolve this(aside from moving my working copy, or linking on the filesystem)? I'm hoping to find a way in code, or an alternative to work around this limitation(as it appears that SVN 1.7 doesn't have this limitation anymore).

Here's some code?

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.");
                }
            }
        }
    }
}

I also stumbled across this http://subversion.tigris.org/issues/show_bug.cgi?id=3535 and http://subversion.tigris.org/ds/viewMessage.do?dsForumId=463&viewType=browseAll&dsMessageId=2456472

So, since that happened way back when, shouldn't this not be an issue anymore?

Answer 1

A kludge is to ".." your way up to the root from your current directory:

[pwd = C:\USERS\franklin\absrel]
root = ..\..\..

Answer 2

SharSVN has issue with root paths as we can read in mail-archives. However we can made small hack for your occasion:

1. Download full package sharpsvn http://sharpsvn.open.collab.net/files/documents/180/5569/SSvnEx-1.7002.1998.zip
2. Copy svnversion.exe to your bin directory

3. Then we need a hack method to get 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. And modify your fake method full source code

Sure its a dirty work around but it can be helpful. Please be careful with svnversion.exe results GetVersionHack not ideal.
