Handle network failures during project lookup

Navigating to nonexistent change numbers should result in a visual 404,
but if the URL uses a legacy pattern (without the change's project) a
lookup is performed for the nonexistent change number using the REST API
interface's `getFromProjectLookup` method.

When this lookup request fails, the method yields undefined (per its
JSDoc signature), but the undefined case is not handled by the router's
URL upgrade and an attempt is made to redirect to the same project-less
URL. The result is an infinite loop of failing network requests.

With this change, additional handling is added for the case when
`getFromProjectLookup` fails.

The network failures generated by this bug were not being displayed in
the UI because gr-router uses an unattached REST API interface, the
events from which are unable to propagate to the app and error manager.
With this change, the interface is now DOM attached so that the expected
404 message appears in this case.

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.

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 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.
