Fix reading changes from index for older schema versions

Prior to index v27, there is no project field in the index, so we
can't count on the field being present when we need to create a
ChangeData from it. Detect this special case and call a new (well,
reborn) ChangeData.Factory method with an intentionally ugly name.
This sets the project to null initially, and triggers a lazy read from
Changes when looking up the project. In addition to the ugly name,
check that notedb is not enabled; this is a safe assumption, since the
whole point of v27 was to make it possible to read from notedb without
reading from the Changes table.

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.

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 Buck and run the following:

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

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