BUG: Rollback Causes File Label Corruption

Article ID: 193578

Article Last Modified on 10/15/2002

APPLIES TO

This article was previously published under Q193578

SYMPTOMS

When a file is rolled back, previous "File Label" label comments are corrupted. The first eight characters of the label comment are removed. If you run Analyze in autofix mode (-f switch), it removes the entire corrupted label comment.

A "File Label" is a label that is applied to an individual file, not a project. A project label is applied to an entire project and all its sub- projects. This error does not occur with project labels.

RESOLUTION

You can work around this problem by performing the steps in the following article instead of doing a rollback. The major benefit of this method is that it maintains all the history information.

For additional information, please see the following article in the Microsoft Knowledge Base:

MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a new file and add it to the project with a comment of "original comment".
  2. Check it out and make a change.
  3. Check it in with the comment "first comment".
  4. Label it with the label "first label" and the comment "first label comment".
  5. Check it out and make a change.
  6. Check it in with the comment "second comment".

  9. Check it in with the comment "third comment".
  10. Label it with the label "third label" and the comment "third label comment".
  11. Show history of the file. There should be five versions, with labels on versions one, three, and five. Examine each of the Details to make sure that all of the labels and comments are in tact.
  12. Click on version three.
  13. Click Rollback, and perform the rollback.
RESULT: Examine each of the Details.

NOTE: The first eight characters are missing from the label comment on version three.
