Fix external ID cache

The purpose of the external ID cache is to provide external IDs by
account without need to reload all external IDs when one external ID is
changed. To achieve this ExternalIdsUpdate informs the cache when an
update to the external IDs is done so that the cache can apply the delta
to the current value.

The sequence in ExternalIdsUpdate is:
1. update external ID in NoteDb
2. inform the cache about the update

The cache needs to know the old cache value in order to apply the delta.
Instead of getting the old cache value it was wrongly reading the
external IDs from the current revision of the NoteDb branch. Fix this by
passing the old revision of the NoteDb branch to the cache and let the
cache use this revision to get the old cache value. External IDs for the
old revision are normally already loaded so that reloading the external
IDs from NoteDb does not happen.

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.
