I ran a test on Subversion-1.0.4 with this script:
#!/bin/sh
while :; do
echo -n 0 >f
svn ci -m "0" f
echo -n 1 >f
svn ci -m "1" f
done
to see how Subversion performed when it contained lots of revisions. The
result was pretty ok, there were no significant loss in speed. But when
it reached 65536 revisions it aborts with this message before the
checkin is completed:
Sending f
svn: Commit failed (details follow):
svn: Out of date: 'f' in transaction '1ekk'
svn: Your commit message was left in a temporary file:
svn: '/root/many/.many/svn-commit.tmp'
The coredump is 491.192.320 bytes. "svnadmin verify" is able to verify
all 65536 revisions.
$ ./configure --prefix=/usr/local/prg/subversion --with-apxs

I'm not able to compile trunk on none of my Debians (woody and
unstable/sarge) to test this out, trunk doesn't find any of my APRs even
though both libapr0 and libapr0-dev are installed. That should be enough?
libtool: link: cannot find the library `/usr/local/bin/libaprutil-0.la'
make: *** [subversion/libsvn_subr/libsvn_subr-1.la] Error 1
Shouldn't be anything from apt-get in my /usr/local/ anyway.
