Cannot use `mkdir a\b` in shared folder => Fixed in 1.6.6

Same here. I'm using Windows XPpro with ant and my builds all fail because any creation of a directory or file where the creation of a parent is implied fails.

I can successfully do the build when the directory is mounted via samba or if I copy the directory to the guest OS disk. It only happens with a shared folder.

I run fedora core 9, x86_64.

I tried working around this using samba on the host computer and mapping the drive in Windows. This works in that the mkdir-s work properly, but it is over *three* times slower than using the shared folders. For me this is a pretty big hit since my 1 hour system (yes the system is quite large) build goes to over 3.5 hours.

It would be great if we could get some status on if and when this might get addressed.

Problem confirmed. We are currently not sure which part is misbehaving, either our guest additions or the host shared folders service.

Bug fixed in 1.6.6 (not yet released), you need to update the guest additions.

It doesn't appear as if this fix made it in 1.6.6, or it was not complete. I am running a Fedora 9 (AMD64) host with a Windows XP guest. I just updated VirtualBox and installed the 1.6.6 additions. I am still getting the same error when using ant to do a build. The build works fine when using a samba share.

"BUILD FAILED T:\workspace\hre_29\build.xml:301: Failed to copy T:\workspace\hre_29\rulesconfig\drools\CallCenter?\CallCenter?.drl to T:\workspace\hre_29\target\classes\drools\CallCenter?\CallCenter?.drl due to java.io.FileNotFoundException? T:\workspace\hre_29\target\classes\drools\CallCenter?\CallCenter?.drl (The system cannot find the file specified)"

Please could you check if

mkdir foo\bar\buzz

works if foo and/or bar is not present? Use the command line. Because that works fine here and I wonder what is different with your environment.

mkdir foo\bar\buzz does appear to work on my system as well. I also tried xcopy, which works. It looks like it might be an Ant/Shared Folders problem when Ant does a copy. As I mentioned earlier, the Ant build script I am using works fine (just very slow) using samba to connect to the same shared folder. Also FYI, I upgraded to VB 2.0.0.

Without a simple test case this problem is difficult to fix.

When I get some free time, I will see if I can create one.

Paste the following into a file build.xml on a shared folder:

<?xml version="1.0" encoding="UTF-8"?>
<project name="vboxbug1870" default="test" basedir=".">
	<description>Exposes VirtualBox bug #1870.</description>
	<target name="test">
		<delete dir="a" />
		<mkdir dir="a/b/c" />
	</target>
</project>

Install Java and Ant. Then open a command prompt in the folder containing build.xml. Run the command ant.

My output for VirtualBox 1.6.6 is:

F:\vbox-bug>ant
Buildfile: build.xml

test:

BUILD FAILED
F:\vbox-bug\build.xml:6: Directory F:\vbox-bug\a\b\c creation was not successful for an unknown reason

Total time: 0 seconds

It looks like the underlying problem is with java file io. Here is a test program that removes an existing test directory structure if it exists, then creates it again with a single File.mkdir instruction. To run, copy the text below to a file called FileIOTest.java, compile the code with javac, then run "java java FileIOTest" inside of a shared folder.

import java.io.File;


public class FileIOTest 
{
	
	static public boolean deleteDirectory(File path) 
	{
		if( path.exists() ) 
		{
			File[] files = path.listFiles();
		    for(int i=0; i<files.length; i++) 
		    {
		    	if(files[i].isDirectory()) 
		    		deleteDirectory(files[i]);
		        else 
		           files[i].delete();
		    }
		}
		return(path.delete());  
	}

	
	public static void main(String args[])
	{
		String mkdirPath = "vbtrac1870"+File.separator+"foo"+File.separator+"bar";
		File dir = new File(mkdirPath);
		String topDirName = "vbtrac1870";
		File topDir = new File(topDirName);
		
		if(topDir.exists())
		{
			System.out.println("Removing old test directory structure: "+topDirName);
			try
			{
				if (deleteDirectory(topDir))
					System.out.println("-- SUCCESS");
				else
					System.out.println("-- FAILURE - structure not removed, no exceptions thrown");
			}
			catch(Exception e)
			{
				System.out.println("-- ERROR");
				e.printStackTrace();
			}
		}
		
		System.out.println("Creating directory structure: "+mkdirPath);
		try
		{
			if (dir.mkdirs())
				System.out.println("-- SUCCESS");
			else
				System.out.println("-- FAILURE - structure not created, no exceptions thrown");
		}
		catch(Exception e)
		{
			System.out.println("-- ERROR");
			e.printStackTrace();
		}
	}
	

}

Here are my results:

Using samba:

Z:\>java FileIOTest
Creating directory structure: vbtrac1870\foo\bar
-- SUCCESS

Using a shared folder:

T:\>java FileIOTest
Removing old test directory structure: vbtrac1870
-- SUCCESS
Creating directory structure: vbtrac1870\foo\bar
-- FAILURE - structure not created, no exceptions thrown

Oops, the command to run should be "java FileIOTest" not "java java FileIOTest"

Just echoing a "me too" about the problem still happening for me in VirtualBox 2.0 which I'm assuming encompasses "1.6.6". I also use ant so I'll be interested in the results of electricsam's test case.

(I mainly added this comment because there doesn't seem to be a way to add myself to the cc list and I am very much interested in the status of this bug. I use Vbox for compiling Java code under windows and the speed difference between Samba and shared folders is very important to me.)

Please update to 2.0.2 and install the 2.0.2 additions there. The additions installer had some issues before that prevented it from updating some files.

Unfortunately upgrading to 2.0.2 and installing the 2.0.2 additions does not fix the problem. I'm getting the same result from the java test.

T:\>java FileIOTest
Creating directory structure: vbtrac1870\foo\bar
-- FAILURE - structure not created, no exceptions thrown

Is there any new status on this bug? I've upgraded to 2.0.4 and reinstalled the shared folder extensions. I'm developing java applications under a windows guest and I'd love to have this bug fixed: shared folders seem to be about 3-5x faster than a samba mount.

I just tried with 2.0.4. It is still not fixed.
