I think I probably confused things with that second posting. Anyway,
attached is a script which demonstrates what happens where a directory
has been replaced - I think this demo may be more helpful.
Do a show log on "bar" after running the script a compare revisions 2
and 3. This shows file1.txt and file2.txt modified. Clicking file2.txt
will give an error. Clicking file1.txt will do the equivlalent of
svn diff %REPO%/bar/file1.txt_at_2 %REPO%/foo/file1.txt_at_3
Whereas I think it should do
svn diff %REPO%/foo/file1.txt_at_2 %REPO%/foo/file1.txt_at_3
Which is equivalent to
svn diff bar/file1.txt -r2:3
which is the operation I think the user would expect from the GUI in
this case.
REM My CWD is C:\SVN\tests
set REPO=file:///c:/SVN/tests/test_repo
svnadmin create test_repo
svn co %REPO% test_wc
cd test_wc
mkdir foo
mkdir bar
svn add foo bar
svn ci . -m"Add dirs"
echo Text in foo/file1 > foo\file1.txt
echo Text in foo/file2 > foo\file2.txt
echo Text in bar/file1 > bar\file1.txt
svn add foo/*
svn add bar/*
svn ci . -m"Add files"
echo More text >> foo\file1.txt
echo More text >> foo\file2.txt
svn ci . -m"Modify files in foo"
echo More text >> bar\file1.txt
svn ci . -m"Modify files in bar"
svn rm %REPO%/bar -m"Delete bar"
svn mv %REPO%/foo %REPO%/bar -m"Move foo to bar"
svn up
