I have a use case of wanting to be able to create a new tree with the
same file ids as another tree (or subset of the other tree). I used to
do this with a custom Action object, which would grab the file id when
it went to add the entry to the inventory.
Since we now always add the object to the inventory (in __add_one), it
would be nice to have ability to customize file id generation.
My 'add_from' plugin:
Basically hijacks the current __add_one function to add this
functionality. But rather than monkey patching, the attached diff does
what I need.
I already have tests for it, since I'm using it in my add_from branch,
so I would be happy to update bzr.dev, with tests.
And the changes to the Action object, are only for sanitary purposes.
(you always implicitly return None, but since we now expect a result,
explicitly do so).
