It's possible to make HEAD ref to itself #28

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Select "Team > Branch > HEAD > ok"
2. Now .git/HEAD is "ref: HEAD"
3. readRefBasic throws IOException due circular references.

What is the expected output? What do you see instead?

 Circular references shouldn't be created.

What version of the product are you using? On what operating system?

package org.spearce.jgit.lib;

Test case:

import java.io.IOException;

public class BranchTestCase extends RepositoryTestCase {
    public void testSelfRef() throws IOException {
        db.writeSymref("HEAD", "HEAD");
        db.resolve("HEAD");
    }
}

output:
java.io.IOException: Exceeded maximum ref depth of 5 at HEAD.  Circular 
reference?
