Bug ID: 293116
Summary: diff incorrectly reports "Directory loop detected"
Product: Base System
Version: Unspecified
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
diff reports "Directory loop detected" even when there isn't such a loop.
Simple test:
cd /tmp
mkdir -p x/b y/a y/b # /tmp/x and /tmp/y don't exist
ln -s b x/a
diff -r x y
It will report
diff: x/b: Directory loop detected
The issue seems to be following symlinks when it shouldn't. There is a command
line option "--no-deference" but that is not quite right. Note that gdiff does
not have this problem.
