Bumping Python requirement to (at least) 2.2
We currently require Python only for the build-from-checkout and test
system, not for building from tarballs. We require 2.2 for Windows
and 2.0 for Unix.
Here is a timeline:
21-Dec-2001: Python 2.2 released.
23-Feb-2004: Subversion 1.0.0 released.
30-Nov-2004: Python 2.4 released.
17-Oct-2007: I am writing these words.
I think we should bump the Python requirement to at least 2.2, if not
2.4. This will let us use modern features like subprocess (which
comes with 2.4 and works with 2.2) in the test suite. There's a nice
table in http://www.python.org/dev/peps/pep-0291/ which shows what
language features we would be able to use.

+1 (but doesn't count because I'm not a full committer)
FWIW, cvs2svn has required Python 2.2 since August 2006, and nobody ever
complained. And generator functions are really fun :-)
I don't think the time is ripe to require Python 2.4 yet, though.
For cvs2svn, we have a couple of modules to add 2.4-like features to
Python 2.2; see
http://cvs2svn.tigris.org/svn/cvs2svn/trunk/cvs2svn_lib/...
boolean.py
process.py
set_support.py
though from recent discussions it sounds like we could include Python's
process module instead of using our module.

I don't have any pull here but I would agree. Python has matured a
lot since 2.0 and supporting older versions means a lot more code.
subprocess is a great example. We may even be able to make the test
suite smarter and more efficient because of it.
Take care,
Jeremy

Oops, I remembered wrong... my proposal was just to 2.2. This below was the
only objection to 2.4. And it's been over a year. And python is not
necessary to install from tarballs, recall.

I suggest bumping to 2.2 since RHEL 4, which is still in a lot of places, is
on 2.3. To have to build Python 2.4 or greater just to test svn on RHEL 4
would be a pain.
So bump to Python 2.2 but include subprocess.py with the svn test suite.
