bzr: copy file from one branch to another unrelated branch

Is it possible to copy a file from one branch to another unrelated branch while preserving history for that file?

Bazaar has no direct support for this operation.

Though you can achieve this goal with additional tools. But it's not very trivial operation. You can use bzr-fasimport plugin to export full history of your branch into fastimport stream, then filter history for required file and create new branch with only this one file and its history:

bzr fast-export > full-branch.fi
bzr fast-import-filter -i foo.txt full-branch.fi > only-foo.fi
bzr fast-import only-foo.fi foo-only-branch

Then merge foo-only-branch into your destination branch

bzr merge /path/to/foo-only-branch -r0..-1

NOTE: after fast-export/fast-import dance the history of only-foo will be incompatible with original branch, so you can't do this trick several times.
