NullPointerException when browsing repo with empty or non-existing master branch #823
Description
Originally reported on Google Code with ID 527
It seems Gitblit chokes when a repository it hosts either has no master branch, or a
master branch with no commits. The repository has other branches with commits, but
these commits cannot be viewed without Gitblit throwing a NullPointerException.
What steps will reproduce the problem?
1. Set up Gitblit GO (add SSH key for admin user)
2. Create new repository "example.git" via Gitblit web interface
3. On workstation run "git init example.git"
4. cd example.git
5. git checkout -b develop
6. touch foo.txt
7. git add foo.txt
8. git commit -m"Add empty foo.txt"
9. git remote add gitblit ssh://[email protected]:29418/example.git
10. git push gitblit develop
11. Go to https://gitblit.vm:8443/summary/example.git
12. Click on the commit message "Add empty foo.txt"
13. Observe "Internal error"
What version of the product are you using? On what operating system?
Gitblit GO 1.6.2 on an Ubuntu 12.04 Vagrant VM
