Run this recipe:
#!/bin/sh
URL=file:///`pwd`/repos
rm -rf repos wc
svnadmin create repos
svn co -q ${URL}/ wc
# Add a file.
echo "This is the original file." > wc/file
svn add -q wc/file
svn ci -q -m "Commit original file." wc
svn up -q wc
# Replace the file.
svn rm -q wc/file
echo "New file, new contents." > wc/file
svn add -q wc/file
# Show the diff.
cd wc
svn diff
You'll see a difference between the old and new files:
Index: file
===================================================================
--- file (working copy)
+++ file (working copy)
@@ -1 +1 @@
-This is the original file.
+New file, new contents.
... even though they are not related and should not be diffed against each
other! Probably a more correct behavior would be to show two separate file
diffs, one containing all deletions, followed by another containing all additions.
Note that diff_tests.py 4, diff_replace_a_file(), currently expects the above
bogus behavior.
This may be related to issue #1675, not really sure.
