I don't think issue 4500 should delay 1.9.0.
This is about representing tree conflicts on merges where there are 4 interesting revisions.
On a merge we merge the difference between URL1 and URL2 into a working copy which was original from URL3, but can have local changes.
The problem described here is that we don't describe URL3 in the merge-info skel. Personally I don't think we should ever describe this in the skel, as we already have all that information in NODES. Duplicating the information requires keeping it synchronized...
I think it is better to obtain that information (if we need it) directly from BASE. (A simple svn info X + svn cat X (or svn info X_at_BASE + svn cat x_at_BASE on deletes) provides all of the info we have for the other URLs and even a bitmore
On Update/Switch URL1 and URL3 are the same thing, so in that case we do store the information.
Duplicating the information will require some form of working copy format bump as the conflict skels will no longer be backwards compatible with 1.8.
Note that for the property conflicts described in the conflict the 4 way information is already implemented: It just fetches the nodes from the PRISTINE layer in NODES.
(It used to fetch them from BASE, but I recently fixed that... as op-depth 0 doesn't have to exist; especially during merges)
