ChangeNotesParser parses the commits in a change meta ref starting from
the most recent commit. While doing so it keeps track of patch set
creations. If during the parsing we observe meta data for a patch set in
a meta commit that was created before the patch set got created we fail
with a ConfigInvalidException. This works well, unless a patch set got
deleted and then recreated. In this case both patch sets have the same
patch set ID and when we hit the meta data for the deleted patch set we
find that it was created before the patch got created the second time,
and hence the exception is thrown. This means we currently cannot load
any change for which a patch set got deleted and then recreated. This
can affect all kind of operations that need to load such a change. To
fix this we are now skipping the parsing of meta data for deleted patch
sets completely, since it's anyway of no relevance.
Patch set deletions are no longer possible via the REST API, but they
were possible when we supported draft patch sets. Hence this bug affects
mostly old changes. Still even nowadays it can happen that a patch set
is marked as deleted. This happens if the ConsistencyChecker is run to
fix change inconsistencies. If the ConsistencyChecker finds a patch set
for which the commit is not found, the patch set is marked as deleted.
At Google we observed more than 200 exceptions that are caused by this,
just in the last month.

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.

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.
