In case you hadn’t noticed, I’m a bit of a stickler for terminology. So, after hearing the popular, yet misleading, JavaScript term “self-executing anonymous function” (or self-invoked anonymous function) one too many times, I’ve finally decided to organize my thoughts into an article.

In addition to providing some very thorough information about how this pattern actually works, I’ve actually made a recommendation on what we should call it, moving forward. Also, If you want to skip ahead, you can just check out some actual Immediately-Invoked Function Expressions, but I recommend reading the entire article.

Please understand that this article isn’t intended to be an “I’m right, you’re wrong” kind of thing. I’m genuinely interested in helping people understand potentially complex concepts, and feel that using consistent and accurate terminology is one of the easiest things that people can do to facilitate understanding.

So, what’s this all about, anyways?

Team Foundation Server Changeset rollback

Warren LaFrance Leave a comment

One of the new features for TFS 2010 Version Control is the ability to rollback or undo a changeset or check-in inside the product and see it as a new pending change type (and new change type in the history) inside Team Explorer. This feature has been available in TFS 2008 but you had to use the TFS Power Tools. The only gotcha for the TFS 2010 implementation is that you have to use the command-line application tf.exe to actually perform the rollback operation. More information about the tool is available here in the MSDN Library: http://msdn.microsoft.com/en-us/library/dd380776(VS.100).aspx

Syntax:

tf rollback /changeset:changesetfrom~changesetto [itemspec] [/recursive]
[/lock:none|checkin|checkout] [/version:versionspec]
[/keepmergehistory] [/noprompt] [/login:username,[password]]

tf rollback /toversion:versionspec itemspec [/recursive]
[/lock:none|checkin|checkout] [/version:versionspec]
[/keepmergehistory] [/noprompt] [/login:username,[password]]

Example:

Admin Console Changeset

VS 2010 Powertool changeset

Using the Power Tools for VS TFS 2010  UI method

If you have the August 2011 or later version of the TFS 2010 Power Tools installed, you now have the ability to fire off a rollback straight from Team Explorer without having to use the command-line approach.  The main way would be to fire it off from the Source Control Explorer window.
