Dear fans of move tracking,
I heartily invite you to help by playing with 'svnmover'. Can you have
a go and see what it can do? It's quite fun to play with (in a nerdy
way :-)
To get it, build the 'move-tracking-2' branch and look in
'subversion/svnmover/svnmover' -- it's a sibling to 'svn' and
'svnmucc'.
It's fairly easy to pick up as you go along. There's a transcript
below, as an example. You can also see in the IRC history [1] where I
guided Brane through playing with it for the first time.
You can try
- doing renames/moves (using 'mv PATH1 PATH2')
- merging those changes onto another branch ('merge FROM TO YCA')
- visualize what's happening ('branches PATH', 'ls PATH', 'ls-br-r')
- type 'help' to see usage message
You should find that it copes perfectly with renames inside renames, and so on.
Do please share any thoughts or questions you have --
* about the model
* do you grok the way moves work in svnmover?
* any new feature 'svnmover' should have to help with experimenting?
I believe we can build a move-tracking design for Subversion. This
stage is not trying to give the final answer, it is squarely aimed at
exploring and understanding how it could and should work. So I need
*your* input, please, if you can spare some thought cycles and
experimentation cycles.
Here's an example transcript.
