svn diff Changed Behavior in SVN 1.9

[Jonathan Bedard <jb...@apple.com>]

In SVN 1.9, moving a file with svn move generates an unexpected patch file when running svn diff.  https://bugs.webkit.org/show_bug.cgi?id=166914 has the work-around which WebKit used to fix this issue in our svn support scripts.  Bellow is an example of svn 1.9.4 behavior contrasted with 1.7.19.

1.9.4:

Index: a.txt
===================================================================
--- a.txt	(revision 210689)
+++ a.txt	(working copy)
@@ -1,2 +0,0 @@
-Line 1
-Line 2
Index: b.txt
===================================================================


1.7.19:

Index: a.txt
===================================================================
--- a.txt	(revision 210689)
+++ a.txt	(working copy)
-Line 1
-Line 2

Newer versions of svn emit a file index without a body.  This seems to violate the intention of an index.

You probably want 'svn diff --no-diff-added'.
