I'm trying to merge a branch into a sparse checkout (all the files I touched in the branch are included in the checkout) and I'm getting the following error:
Cannot reintegrate into a working copy not entirely at infinite depth
Does this mean what I think it means? That you have to have a fully recursive checkout in order to merge into?
Just an update for anybody that stumbles across this (like I did)...
SVN 1.7 now supports this functionality. I haven't tried to reintegrate yet but merging a range of revisions seems to work well.
TortoiseSVN 1.7 also has some nice features for working with sparse checkouts.
