Optionally push opening repo into ChangeKindCacheImpl.Loader

The ChangeKind cache is persistent and should have a very high hit
rate. Thus opening the repository before every call to getChangeKind
is potentially very wasteful, particularly if called in a loop during
ChangeJson. Allow the Repository args to ChangeKindCache to be
@Nullable, and open the repo lazily from Loader#call() only if a cache
load happens.

There is still a path in ChangeJson where we need to open the repo to
get commit info. We punt on that path for now and continue opening the
repo in a loop. Fortunately none of these options are used in search
results in the UI. Contrast this with ChangeKindCache which is now
used to populate the revision fields in each ChangeInfo.

Gerrit Code Review

Gerrit is a code review and project management tool for Git based projects.

Objective

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.

Documentation

For information about how to install and use Gerrit, refer to the documentation.

Source

Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.

Reporting bugs

Please report bugs on the issue tracker.

Contribute

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.

Getting in contact

The IRC channel on freenode is #gerrit. An archive is available at: echelog.com.

The Developer Mailing list is repo-discuss on Google Groups.

License

Gerrit is provided under the Apache License 2.0.

Build

Install Buck and run the following:

    git clone --recursive https://gerrit.googlesource.com/gerrit
    cd gerrit && buck build release

Install binary packages (Deb/Rpm)

The instruction how to configure GerritForge/BinTray repositories is here

On Debian/Ubuntu run:

    apt-get update & apt-get install gerrit=<version>-<release>

NOTE: release is a counter that starts with 1 and indicates the number of packages that have been released with the same version of the software.

On CentOS/RedHat run:

    yum clean all && yum install gerrit-<version>[-<release>]

NOTE: release is optional. Last released package of the version is installed if the release number is omitted.
