Evil twin - could this happen in RTC?
Hi
ClearCase users sometimes got themselves into a knot with the so-called Evil Twin problem. Very simply, a user would remove a file and recreate it - leaving the original file in the system as well as the new version - with different people working on different files depending on where they were "looking" with their view. The remove was actually removing the name from the directory record (cc cmd is rmname). Is it possible to do the same thing in RTC (accidentally of course)? thanks anthony |

This can't happen in RTC. But you can get evil-twin conflicts when different users add the files/folders with the same name. For an outline of how RTC supports add/add evil-twins see:

Just for interests sake, what is it that can't happen in RTC?
In particular, in RTC, a user can remove a file and create a new file with that name, resulting in different files working on different files with the same name. I believe the only difference between CC and RTC in this regard is that in CC, the file by this name is recorded in the directory version, while in RTC, the file by this name is recorded in the configuration.

Just for interests sake, what is it that can't happen in RTC? Ah - when I tried to create the situation in RTC to see how it would behave - I found that my new file had a new (and a very short) history, and looking back in the component history, I could pick out the original file and see its (longer) history. This is how I expect things to work. My (mis?)understanding was that the ET effect in CC was that CC thought it was just a new version of the file. anthony |
