FIX: A hotfix rollup is available for Team Foundation Server 2010


A hotfix rollup is available for Microsoft Visual Studio Team Foundation Server (TFS) 2010. This hotfix rollup includes all the previously released hotfixes that are described in the following Microsoft Knowledge Base (KB) articles:
2725894 FIX: You cannot connect to a project in a Team Foundation Server 2010 server
2696878 FIX: "The field '<field>' contains a value that is not in the list of supported values" error message when you save a work item of a team project that is created in TFS 2010
2687761 FIX: Merge results between two branches are incorrect after you roll back a merge of a renamed folder, and corrupted file content is saved in Team Foundation Server 2010 version control
2655761 FIX: Time out occurs when Team Foundation builds are waiting for build agent reservations in Visual Studio Team Foundation Server 2010

This hotfix rollup also includes fixes for the following issues in TFS 2010:
  • The test adapter runs for longer than expected when it tries to rebuild a warehouse.
  • The test adapter experiences a primary key violation error and stops working when it tries to clear test results from a warehouse.
  • The test adapter experiences a timeout error and stops working when it attempts to clear test results from a warehouse.
Note The changes that are introduced in this hotfix rollup target performance and reliability aspects of the test adapter in TFS 2010.

After rebuilding the warehouse, the test adapter handles two main workloads. The workloads pump data from the project collection database to the warehouse and process deletion events. The changes in this hotfix rollup make the test adapter avoid deletion event processing. This reduces the running time dramatically. This change applies only to the first time that you run the test adapter after rebuilding the warehouse. 

Other changes that are introduced in this hotfix rollup improve the reliability of deletion event processing by implementing batching that scales with data size. Additionally, this hotfix rollup improves the performance of the test adapter when it pumps data into the warehouse.

This hotfix rollup does not initiate a rebuild operation of the warehouse during installation. Additionally, you do not need to rebuild the warehouse after installing this hotfix rollup.
