Multiple Rollback

Create a new article. Make 2 or 3 edits to the article.
Go to the History tab, and click "Undo" next to the first edit in the list.

Does it work correctly and undo the last edit?

For me it does this:
1. Undoes the last edit. Then creates a new edit that matches the original (before any edits).
OR
2. Undoes the last edit, but the text is truncated. Then creates a new edit with no text. The one with truncated text is applied to the article.

I tried this on a short edit (i.e. not much text) and I got result 1.

Do you have the Web Developer toolbar installed and active when you do this? After 11 hours working on this, I just figured something had to be sending a duplicate request (without the postvars), and this is the only thing I know of that does this.

The fix seems to have dealt with result #1, now to see how result #2 goes.

No, not using that toolbar. Sounds interesting. What's it do?

This is fixed for the next build by making sure all the necessary postvars are there. Now if a second request occurs, the duplicate revision error would be triggered as originally intended.

#2 happened because the type of compression we are introducing in 2.5 for the revision table doesn't play well with mysql_ functions unless the compressed data is also encoded in the database.

The Web Developer toolbar has quick access to a number of settings allowing you to disable the cache or javascript, or view the response headers, or validate HTML, CSS, etc. There's a lot more it does as well but this is mainly the extent to which I use it.
