Bug 135381 – [webkitpy] Make diff_text generate correct diff if there is no newline at the end of file

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Tibor Mészáros]

If only one line break is the difference between the actual and expected result, the pretty diff will fail.

Example:

actual result:
 "A\n\nB"

expected result:
"A\n\nB\n\n\n"

current diff:
"--- exp.txt
+++ act.txt
@@ -1,3 +1,5 @@
 A
 
-B+B
+
+"

expected diff:
"--- exp.txt
+++ act.txt
@@ -1,3 +1,5 @@
 A
 
-B
\ No newline at end of file
+B
+
+"
