GetBestWorkingFolder and Get latest file

random · Post by **random** » Tue Apr 29, 2008 12:01 pm

I am having issues with getting the latest version of a checked-out file. I am able to connect and checkout the file; however, Get fails with a GetLatestVersionFailedException because I do not have a working folder.

I have attempted to use both GetBestWorkingFolder and GetWorkingFolder to no avail. They both always return null. From what I understand, GetBest* works with inherited working folders while GetWorkingFolder works with explicit working folders. I have setup both scenarios and am still unable to get a working folder.

Is there something that I am missing?

can you post a code snippet?

Absolutely! Thanks for your help

VaultClientFolder folder = m_client.Repository.Root.FindFolderRecursive( workingFolder );

if( folder == null )
return null;

// Get the working folder otherwise Get will fail.
if( m_client.TreeCache.GetBestWorkingFolder( folder.FullPath ) == null )
return null;

m_client.Refresh();

// TODO should check responses to see if there were errors
VaultClientFile[] files = VaultConnection.GetFiles( folder, fileNames );
VaultLib.VaultResponseItem[] responses = m_client.CheckOut( files, VaultLib.VaultCheckOutType.CheckOut, "" );

// We must do a get after the checkout otherwise the client will not be aware that the file
// exists locally and will not be able to check in later.
if( VaultConnection.GetLatestFiles( files ) )
return new List<VaultClientFile>( files );

return null;

Probably self-evident, but m_client is an instance of the ClientInstance class that has previously been created and is connected to our Vault server.

Also, I made sure that the version of the assemblies and the vault server are the same.

I forgot to ask, what version of the api are you using?

random · Post by **random** » Wed Apr 30, 2008 9:08 am

4.1.1.18060

our VaultConnection class doesn't have a GetFiles or GetLatestFiles method, is this a class you wrote?

random · Post by **random** » Wed Apr 30, 2008 9:38 am

It is. Here is the code for those methods:

private static VaultClientFile[] GetFiles( VaultClientFolder workingFolder, List<string> fileNames )
{
if( !m_isConnected )
return null;

try
{
List<VaultClientFile> list = new List<VaultClientFile>();

foreach( string fileName in fileNames )
{
if( workingFolder.HasFile( fileName ) )
{
foreach( VaultClientFile file in workingFolder.Files )
{
if( file.Name == fileName )
list.Add( file );
}
}
}

return list.ToArray<VaultClientFile>();
}
catch
{
}

return null;
}

public static bool GetLatestFiles( VaultClientFile[] files )
{
try
{
m_client.Get( files, true, MakeWritableType.MakeAllFilesWritable, SetFileTimeType.Current, MergeType.OverwriteWorkingCopy, null );
m_client.Refresh();
return true;
}
catch
{
}

return false;
}

It is the call to the Get method in GetLatestFiles that is throwing the GetLatestFailedException because of the lack of a working folder.

How are you setting the working folders? Can you log into the gui client and see that they've actually been set?

random · Post by **random** » Wed Apr 30, 2008 9:47 am

I can. The root ($) folder is set to "d:\localdev.net" and I force the inheritance of all subfolders. I also tried explicitly setting a working folder but the result was the same.

I'm working to figure out your problem, but it's taking some time. Can you give me the exact exception information, maybe a stack trace?

Just a note: the file is successfully CheckedOut using the API before the Get method is called.

Are you setting your working folders using the gui client or in code with the api?

Can you successfully do a get on one of the files from the gui client? (make sure the file needs a get when you test this, i.e. old)

random · Post by **random** » Wed Apr 30, 2008 10:59 am

Working folders are set in the GUI client. I can do a getlatest without issues through the GUI client.

shannon · Post by **shannon** » Wed Apr 30, 2008 11:48 am

Please insert a call to m_client.TreeCache.GetWorkingFolderAssignments before your call to GetBestWorkingFolder and see what it returns.
