Say you "Update" a local svn from a remote repo. For clarity, say the update will have 100 items (new files) totalling 1gb.
Say the net breaks and the Update is stopped half way through. (Or, you deliberately cancel the update). Say it has downloaded 50 of the new files, .5 gb of files.
In fact, are the 50 files actually placed in your local copy?? They become part of your local version?
or (2), does it "hold on to" those files locally (to avoid downloading them again) and then use them only when you can get a whole successful update
or (3), was the partial download a completely waste: it starts over.
Surprisingly I could not find the answer to this anywhere.
