Notedb: Fix reviewedBy computation in ChangeData

To find which users have reviewed a change we find all users that have
posted a message or uploaded a patch set after the change owner has
posted a message or uploaded a patch set. To do this we internally
created ReviewedByEvents based on the changes messages and the patch
sets and sorted them by date. When two actions were done with the same
timestamp this could result in a wrong order. E.g. the owner uploads
patch set 1 and then a user posts a review, we have 2 change messages
and 1 patch set and they all can have the same timestamp. For the
change message the correct order is guaranteed by respecting the order
of the commits on the refs/changes/XX/YYYY/meta branch, but doing a
sorting by timestamp in the reviewedBy computation may result in a
wrong order. Because of this the
ChangeIT#checkReviewedFlagBeforeAndAfterReview() was flaky when
notedb was enabled. To fix the issue the sorting by timestamp is
removed from the reviewedBy computation. This is possible by only
relying on the change messages and not considering the patch sets.
It's OK to ignore the patch set because any patch set creation also
creates a change message.

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

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 instruction how to configure GerritForge/BinTray repositories is here

On Debian/Ubuntu run:

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.
