Thanks for the summary, Trent.
Some history here:
Subversion does require Python 2.0 for a reason: there's some code in
the test suite that uses a feature that wasn't available in 1.5.2. I
frankly don't remember exactly what the issue was, I just remember
that Mike Sussman or Ben discovered that something didn't work with
pre-2.0 Pythons, did a little research, and found out that we'd made
use of a feature new in 2.0. In other words, 2.0 turned out to be
backward-compatible but not forward-compatible with 1.5.2... as is
usually the case with languages, I suppose.
SOLUTION:
I doubt it's worth it to make the test suite run with 1.5.2 and 2.0,
since the 2.x series will probably be widespread fairly soon.
However, since some OS's are apparently installing Python 2.0 as
"python2", if we can make Subversion check for "python2" during the
configure-time search for a useable Python, and then substitute
"python2" in the appropriate places if it finds it, then things should
work correctly for more people.
Any volunteers, preferably someone with a box that has both Pythons
installed?
