This seemed like a great plan; many backs were slapped, high-fives initiated (and returned!) and egos inflated. We are genius! So I don't know about the other guys, but I've been sleeping like a newborn baby knowing that all our bases were covered. I think you know where this is going. Except it's not. But it almost did.
Basically, papa-to-be was curious why some tests were failing and asked if I could unshelve his latest change and give it a look-see. When I went to do so, I got the following lovely error:
SupportTestData.xls is locked for check-out by INSERTCOWORKERHERE in workspace COWORKERSWORKSPACE.
Umm, that's not good. You see, xls is binary, so you can't share a check-out. And I can't download a shelveset unless I can check out every file. This is apparently a 'feature' of TFS, because hey, shelving isn't made for sharing, that's just a nice side-benefit, so don't expect it to always work the way you hoped it would.
Thankfully we discovered this pre-stork. Now we have the knowledge that he can simply undo his pending changes following his shelves, ensuring that there are no locks if he never comes back.
