Destroy old data in TFS

Team Foundation Server only performs soft deletes and the files are very easy to recover just by performing an undelete. After a while the deleted files may use a lot of unneccesary space. From TFS 2008 it is possible to erase the data from the database. On option would be to use tf.exe and the destroy command. That however will be pretty tedious when there is more than one file that should be destroyed. I have created a small application to help with this task.

The TFS communication is handled in a separate class which i very simple without any error handling.

using System;
using System.Net;
using System.Windows.Forms;
using Microsoft.TeamFoundation.Client;
using Microsoft.TeamFoundation.VersionControl.Client;
using Microsoft.TeamFoundation.VersionControl.Common;

namespace TFSCleanupTool
{
    internal class TFS
    {
        private string ServerName = null;
        private VersionControlServer VersionControl = null;

        internal TFS(string servername)
        {
            ServerName = servername;
        }

        internal void Connect(string domain, string username, string password)
        {
            TeamFoundationServer server = new TeamFoundationServer(ServerName, new NetworkCredential(username, password, domain));
            server.Authenticate();
            VersionControl = (VersionControlServer)server.GetService(typeof(VersionControlServer));
        }

        internal Item[] GetDeletedItems(string path)
        {
            ItemSet itemSet = VersionControl.GetItems(path, VersionSpec.Latest, RecursionType.Full, DeletedState.Deleted, ItemType.Any);
            return itemSet.Items;
        }

        internal void DestroyDeletedItem(Item item)
        {
            ItemSpec itemSpec = new ItemSpec(item.ServerItem, RecursionType.Full, item.DeletionId);
            VersionControl.Destroy(itemSpec, VersionSpec.Latest, null, DestroyFlags.None);
        }
    }
}

Usage of this class is very simple and this is just sample.

TFS tfs = new TFS("server");
tfs.Connect("domain", "username", "password");
Item[] items = tfs.GetDeletedItems("$/");
foreach(Item item in items)
{
    tfs.DestroyDeletedItem(item);
}

This class only handles already deleted files. It is possible to destroy non-deleted files as well, but I do not really see the point in that. Keep in mind that the data will be permanently removed and cannot be restored, so be careful! Always back up the TfsVersionControl database before using the destroy methods.

LEAP Sweden - Identity & Access Management

Today was the third day of the Swedish Lead Enterprise Architect Program at Microsoft in Kista. It has been a day filled with sessions on security and identity with a kind of unavoidable focus on federated identities in the cloud. Overall it has been an awesome day with seminars from Henrik Nilsson , Barry O'Reilly and Sergio Molero among others. A lot of Microsoft technologies was mentioned, Forefront Identity Manager , Active Directory Federation Services 2.0 , Forefront Unified Access Gateway , Direct Access ,  Windows Identity Framework and of course  Azure Access Control Service . Microsoft really has a great suite of applications regarding Identity & Access Management. I just wish there was a project or two where I could utilize all of these amazing technologies. I have had a plan to add a login feature to the Cornball using federated identities, so that might happen in the near future. Besides, Björn Eriksen provided a tip for all of us thursty for e...

The Cornball goes to Brunch with Chaplin

Lately I've been working pretty hard on different projects but not really stumbling upon anything blogworthy. The most recent project is quite interesting though, a single page, touch friendly, web application using the latest and greatest technologies. We've ended up with using Brunch with Chaplin , which is a very neat way of setting up a Backbone based single page web project with Brunch and Chaplin . Aside from this, I have my own little project that has lived on for almost 15 years already, The Cornball . From being a plain Windows application written i C an Win32 API, it has been ported to .NET using WPF, and is currently a Silverlight application hosted on Windows Azure. I could not find a better time to reanimate this project and create a new web based version, touch friendly, super optimized, awesome in any way. So I did... So please follow my journey at Github . It's going to take a while, I assure you, but I already have some ground work done. Meanwhile,...

Using ASP.NET MVC with MEF

I wrote this post almost a year ago, but never published it for some reason. Anyway, here is a little MVC/MEF magic. By default a controller in MVC must have a parameterless constructor. When using MEF a good practice is to inject the services via constructor parameters. These two in combination obviously creates an issue where the following scenario will not work out of the box, since there is no parameterless constructor for  MVC  to use. Note that the PartCreationPolicy is set to NonShared since a new controller have to be initialized for each request. [Export] [PartCreationPolicy(CreationPolicy.NonShared)] public class HomeController : Controller {     private readonly IServiceClient _service;     [ImportingConstructor]     public HomeController(IServiceClient service)     {         _service = service;     }     public ActionResult Index()     {         ...
