Regarding this issue: http://subversion.tigris.org/issues/show_bug.cgi?id=3311
We don't support using --depth options other than infinity with externals. Bert mentions that wc-ng should make it easier to implement this. However, given the way svn:externals can be defined I think that it's really hard to implement this without a performance hit or without having users frustrated by the way it works. In particular you can define svn:externals at a different level than where you're putting them. If we wanted this to work the way most people I think would expect them to work you'd end up needing to walk all the way up to the repo root looking for externals on every checkout/update. Which stinks. We could punt on that but I'm not sure I like the idea of just continuing to apply hacks upon a poor design. So I'm wondering if it wouldn't be better to just replace externals with something that resolves a lot of other issues and gives us a more consistent behavior. While leaving the existing externals implementation alone. What does everyone else think? Anyone have put any thought into replacing externals?
