It's still valid. The problem is that if something changes in a subdir, the
server sends the changes, and the client chokes, since by this point it's
never heard of the subdirs.
There are two possible solutions that I can think of.
1) The client maintains state, and sends to the server during an update: "I
have base-rev X, but I'm not interested in changes within foo, bar, or bazz."
The server sends a normal update response, but excludes the parts the client
said it wasn't interested in.
2) The client maintains state, and sends a normal update request, then filters
the results for the subdirs it's not interested in.
I think 1 is a preferred solution, but two affects less code.
Just in case you wanted one, heres a repro recipe. If someone could add this
to the issue, it might help me not have to answer this question every month or
so. (I guess if I just fixed that would do it too :)
svnadmin create repo
svn co file://`pwd`/repo wc1
cd wc1
mkdir a
touch foo
touch a/bar
svn add a
svn add foo
svn add a/bar
svn ci
cd ..
svn co -N file://`pwd`/repo wc2 # get only foo here.
cd wc1/a
vim bar # make some changes
svn ci
cd ../wc2
svn up #watch the client choke because it's never heard of a/bar.
