How do I remove a file from history?

Asked by Stuart P. Bentley

I have a project where I'm developing a library, and I also included a file for a test application. I've decided now that I want to keep the main branch free of any applications and do any apps in branches, so how can I change the main branch to only include the other files in its history (as in, making a branch with all the same files except the app one and swapping the branches afterward)?

I think you can do this history editing using bzr-rewrite?

You can just remove the subdirectories from your main branch. (see also bzr split --help)
I would not recommend rewriting history unless you don't want to disclose your secret source recipes or the additional history is really too big to hunk around.

@Martin Pool: How would I do that?
@Marius Kruger: The file isn't in a subdirectory.

Well as I said you can just remove it: `bzr remove unneededfile` .
But if it is very big or if it contains secret stuff then you can try rewriting history.
To that you can use the lp:bzr-fastimport plugin see:

Can you help with this problem?
