give me a while to look at the SVN code/do some research, and i'll give
some candidates.
for now, what about a 'tar' library? it doesn't compress, but it still
addresses all the issues, and i'm pretty sure it's stable and handles
big files...

honestly, i don't know enough about apr or how it works to comment. can
you recommend some documentation?

while i agree that it is reasonable to expect that a SVN client should
be SVN aware, the bigger issue is, why should we require that any
application be SVN aware? that would only limit its acceptance. the
point i was trying to make was, if even a SVN client doesn't play well
with the current SVN scheme, how can we expect/require that other apps
do so?

just because a lot of other VCS systems had this limitation is not
justification for SVN to keep it.

once again, the most popular IDE on the planet does not. and as MS has
proven many, many times, you cannot expect them (or any other company)
to go out of their way to ensure that other *competing* products work
with their product. if anything, you can expect the opposite. i'm sure
Bill Gates is *not* particularly distressed that VS7 doesn't work with
an open-source VCS and that developers will have to use Microsoft Visual
Source Safe instead. i don't know for sure, but i would imagine that
fixing how a competitor's software works with their product is *not*
high on the MS list of priorities. like it or not, VS .NET is *the* big
IDE. ensuring that SVN works with it is up to SVN and no one else.

most tools treat non-source/non-config files atomically, and ignore
files they don't understand. this is exactly the behavior we want and it
would fix many more problems than it created, if it created any.

but again, you are avoiding the central question: doesn't it make more
sense to make SVN work with other products than to require that every
other product on the planet be SVN-aware? AFAIK, this is the easiest way
to do that, short of moving the .svn directories out of the source
folders. and i think we can agree that is not where we want to go.
