Current Testing Situation

[This is mostly for Ben, but the rest of you might care as well.]

There are a number of problems that are currently causing the entire
python testsuite to fail.

1. xml_tests has not been updated to reflect either the changed
locations of some functions (like svn_wc vs svn_tree), the new names
(wc_to_tree vs build_tree_from_wc), or the new return values. These are
just mechanical changes.

2. Either you neglected to commit, or just didn't like, the code to
convert entries files to a tree. This naturally makes using such code
hard.

3. The expected output for test 2 is a bunch of regular expressions,
which do not translate nicely to a tree.

4. The comparison function is not smart enough to understand that some
nodes lack of content is not a statement about the content, but a
statement about where the node came from. Therefore, it doesn't like
comparing a node from output paths to a node from a real file. It's
possible to hack around this by extending compare_trees so that it can
be told not to look at contents or props. But this should be done
automatically.

5. A number of the tree creation functions that you wrote
(tree_from_checkout, wc_to_tree) include the working copy directory,
called something like wc-t1, in the tree structure. This is a
mistake, since the name of that directory is arbitrary and not
controlled by subversion. Also, this makes it hard to compare trees
from two different working copies. I managed to kludge up your
wc_to_tree function to skip this dir, but didn't know how to for
tree_from_checkout.

Working around problems 1 and 2 was easy. Problem 3 I skipped, since
it relates to a more difficult issue I brought up in my last mail. I
kludged solutions to parts of 4 and 5. This got me to the point where
3 of the 4 tests pass. However, better solutions need to be found for
3, 4 and 5.

Ideas?
