Description

We use TFS preview (our service is at dataarms.visualstudio.com).

14.02.2013 i had deleted project "Root Project", "Test Project1" and "Test Project2" as described here - http://social.msdn.microsoft.com/Forums/en-US/TFService/thread/81997146-a64f-43fb-9952-57d71542cd11.

15.02.2013 another developer commited his change 187 in project "DWH Искрателеком". Real change was in few files, that was checked-out before 14.02.2013.

One day later i get lastest version of "DWH Искрателеком" and found, that most of files are deleted in changeset 187!

We think, that deletion of pojects may bring deletion of files in next commit (for another projects).

Of course, with software, there is ALWAYS a possibility of a bug :). That said, from the greatly differing behaviors of tfsdeleteproject and deleting a group of files in a checkin I am VERY confident that these are unrelated. It does not however mean that your developer didn't hit another issue that is causing confusion here. I'd love to hear more about what the developer was doing and what they expected to happen versus what actually happened. Let's start with changeset 187. Did the developer attempt to check in any changes around the time that changeset 187 was created? If so, what changes did they think they were submitting and what was the workflow they used to create and submit those changes?

Furthermore, if you need the files that were deleted back, you can always rollback changeset 187. Let me know if you need directions on how to do this.

Thanks,
Taylor

Taylor, are you sure, that destoy of project A can not accidentially delete files in project B at next commit? Is it by design impossible?

You know, it mean, that my developer have deleted files, not software bug.

P.S. Who should i trust - the guy sitting 10 meters from me, or 10 000 kilometers? ;-)

Thanks for the feedback. I took a look at the log files and I think there may be a misunderstanding of the way that TFS works. tfsdeleteproject.exe will *destroy* an entire team project and all of its contents. Destroy is much different than delete. Destroy makes it look like the files destroyed were never present in the system. Delete leaves the history and contents of those files around in case you want them back.

Now, let's talk about delete. In order to delete a file foo.cs in TFS you will first pend a delete on foo.cs and then you will check-in that delete. This works the same way as an edit where you would pend an edit and then check-in that edit. I took a look at the changeset 187 mentioned in your bug. It appears that the developer pended deletes on all of those items and then checked them in.

I am closing this as by design because that is what our logs show as well. If you still have questions, feel free to respond and we'll be happy to answer them and dig in more if needed.

Thanks,
Taylor

If i will try to reproduce, i am worry if i could loose some work on my TFS account. It mean - i need another accouint to try to reproduce, and not sure it will be reproduced (because you have tried).

I think some unregistered by me conditions are lost. I described estimated reproduction steps, not sure steps, because incident happen only once. I have wrote steps by guess - only history is true.

I think more productive would be fact fixation. May you look for TFS request logs (at low level) at 14.02.2013 and say, if change 187 was for delete or for check-in of changed files?
