Show 404 when project lookup fails

Following Ic9c9f0071e, looking up the project of a nonexistent change
would result in a 404 in the getChange REST call. This network failure
would propagate to a visual not-found message automatically and the
router merely needed to stop attempting to redirect when it recognized
the failure.

In I7336ae90d7, the getChange method is updated to use a query because
the former endpoint had been deprecated. However, because the call
became a query, nonexistent changes would yield an empty set rather than
a 404 network error -- consequently, no visual 404 would appear and the
app would appear to hang.

With this change, instead of merely halting when recognizing a project
lookup failure, the router will display a 404.

The new project lookup query is updated to use the change ID operator
query as Ibe82272104 does.

Gerrit Code Review

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

Build Status

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.

Build

Install Bazel and run the following:

    git clone --recursive https://gerrit.googlesource.com/gerrit
    cd gerrit && bazel 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>]

On Fedora run:

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

Use pre-built Gerrit images on Docker

Docker images of Gerrit are available on DockerHub

To run a CentOS 7 based Gerrit image:

    docker run -p 8080:8080 gerritforge/gerrit-centos7[:version]

To run a Ubuntu 15.04 based Gerrit image:

    docker run -p 8080:8080 gerritforge/gerrit-ubuntu15.04[:version]

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