Be more consistent about object ids used in ref operation validation In CreateBranch, a RefUpdate is created with expectedOldObjectId set but not oldObjectId. In DeleteBranch[es], none of expectedOldObjectId, oldObjectId, and newObjectId is set. As a result, when RefOperationValidators uses oldObjectId and newObjectId to create a ReceiveCommand, they can be null, resulting in NullPointerException when a listener dereferences them. So use expectedOldObjectId instead of oldObjectId in RefOperationValidators. Before a ref update has been performed, only the former is meant to be set. In DeleteBranch[es], set the expectedOldObjectId and the newObjectId (which is zero). This way, in RefOperationValidators we know both values will always be set.

Gerrit is a code review and project management tool for Git based projects.
Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.
Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.
For information about how to install and use Gerrit, refer to the documentation.
Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.
Please report bugs on the issue tracker.
Gerrit is the work of hundreds of contributors. We appreciate your help!
Please read the contribution guidelines.
Note that we do not accept Pull Requests via the Github mirror.
The IRC channel on freenode is #gerrit. An archive is available at: echelog.com.
The Developer Mailing list is repo-discuss on Google Groups.
