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?

Your second line of code `var RootPath="d:\";` does not compile (is this your actual source?). Also further down you reference `this.RootPath`, that is a different variable, is that what you intend to do? — heijp06, Feb 03 '13 at 21:14
Yes. Those are filled at runtime, I was just showing what the path was set to. — Kelly Elton, Feb 04 '13 at 18:16
I found the root cause in SharpSvn for this issue. It should be fixed in the next build. It would be much easier for me if you can post this as a small reproducible issue here or on users@sharpsvn.open.collab.net. Showing workingClient.GetVersion("C:\\", out q) as the problem with the exception output is much easier to diagnose then your full example. — Bert Huijben, Apr 08 '13 at 12:41

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

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

If this works and can trick it into reading it properly, that I think this is the right answer. – Kelly Elton Mar 26 '13 at 02:17

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

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

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);
    }

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.

This isn't ideal. It would almost make more sense to temporarily copy the whole svn directory to another location, then get the results. — Kelly Elton, Feb 04 '13 at 18:18
@kelton52 if you can move it to other location better to do it — Sanja Melnichuk, Feb 04 '13 at 19:03
I can't really, and it's a few gig repo...I'm sorry but this solution is too hacky. — Kelly Elton, Feb 04 '13 at 20:08
So wait, does version 1.7002.1998 work with root drives? Or is it only that one file? — Kelly Elton, Feb 05 '13 at 17:25

If it complains about the absolute path then try defining the unc path instead. Share your D:\ drive which is your svn repo. Then access it using

    var RootPath="\\<servername>\D$";
