New issue 1312 by la...@lancehudson.com: Can't get relative submodule  
subscriptions to work
http://code.google.com/p/gerrit/issues/detail?id=1312

Affected Version: 2.3-RC0

What steps will reproduce the problem?
1. Create two projects (A and B)
2. Clone project A locally
3. Create a .gitmodules file in project A
[submodule "B"]
        path = B
        url = ../B.git
        branch = refs/heads/master
4. git submodule init (to check .gitmodules created correctly)
5. git submodule update (to create gitlink)
6. Commit and push the git link and .gitmodule
7. Clone project B locally
8. make changes in project B
9. Commit changes in project B
10. pull project A
11. git submodule update
12. change is not downloaded in submodule (gitlink was not updated)

What is the expected output? What do you see instead?
The gitlink would have been updated and the changes would have shown up in  
the submodule dir.

Please provide any additional information below.

I also have connected to the mysql database running this and do not see a  
subscription in the reviewdb.submodule_subscriptions table.

Looking at the code  
/gerrit/gerrit-server/src/main/java/com/google/gerrit/server/util/Submodule SectionParser.java  
L84

boolean urlIsRelative = url.startsWith("/");

It looks like gerrit requires relative submodules to begin with a '/'. I  
have been unable to get git (msysgit 1.7.9-preview20120201) to work  
properly with a submodule url starting with '/' or './', only '../' works.
