Allow GerritAccount Cookie authentication for Git/HTTP

Since the introduction of basic auth with Change-Id: Ibe589ab2b0,
the mechanism of keeping a session (it was a digest before)
across calls has not been preserved and the basic-auth implementation
resulted in multiple authentications with the configured realm.
Triggering a full authentication handshake could be an
issue when using potentially expensive authentication backends
like LDAP.

Allow to create a Gerrit session from the GerritAccount
cookie set on the Git client, so that only the first HTTP call
will actually authenticate and create a session whilst all
the others would just reuse the existing cookie.

The Git client needs to have HTTP cookies enabled by setting
the http.cookieFile in Git config pointing to a local
file. For keeping HTTP cookies across Git/HTTP commands, the
extra http.saveCookie Git config variable needs to be set to
true.

Previously all Git/HTTP requests were ignored for parsing
the GerritAccount cookie whilst now they are excluded only when
the account token is passed as URL parameter. This problem was
there since the very beginning of the introduction of Git/HTTP
basic auth.

NOTE: Gerrit does not generate HTTP cookies when using
password-based authentication against the external-ids rather
than using the realm: that is expected because it would not
be correct to allocate a cookie when a real authentication
against the realm has not been performed, therefore the
cookie-based authentication for Git/HTTP would not be
available.

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 Developer Mailing list is repo-discuss on Google Groups.

Build

Install Bazel and run the following:

    git clone --recurse-submodules 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.
