Your picture does lack the op-depth part, though; there are N layers between BASE and WORKING, unlike in the filesystem, where we always work against a single (base) revision. (Well, almost always ... the update report is more complex.)
Also note that the working copy may have switched subtrees, or individual files, which IIRC are represented in the BASE, so that would make WC replay somewhat different from repository replay. > I am starting with this streamy I/O layer because I can use it to improve > shelving. > > The "WC replay delta" is simple and about ready to commit.

I understand these APIs could be reused for both shelving and driving/being driven by the RA layer. Could any of them be used by libsvn_client for local working copy modifications? Also is this "just" an additional layer in svn_wc.h, or do you expect to deprecate swathes of the remaining public WC APIs as a result? -- Brane
