Do not request revision information from reply dialog.

For PostReview the web UI currently always requests revision information
to learn about new revisions that have been uploaded concurrently
(uploaded since the change screen was last reloaded). If no revision has
been uploaded concurrently the revision data is computed by backend
unnecessarily, which is expensive and increases the latency of the
response. (the revision data never changes as result of a PostReview
request).

In I30f69f638 Backend was updated to return the current revision number.
With this change we update the logic to only request the revision data
only if needed. Based on the last known patchset in the PostReview
response frontend will trigger the reload if extra information is
required.

Since the revision information is no longer requested and therefore not
present in the response to PostReview, we carry-over existing revision
information from the currently known ChangeInfo. If the
current_revision_number is outdated, we will then schedule the complete
reload of the ChangeInfo. However this reload is explicitly not included
in the SendReply timing information, which completes as soon as
PostReview requests finishes and UI updates.

Within the reply dialog there was another place where an expensive fetch
of all revisions was previously happening. Opening of reply dialog would
request change detail to see if the newer patchset is available. We
update the fetchChangeUpdates to use cheaper getChange() method instead,
since similar to "send" only the number is needed and it's now
available, without extra options.

Gerrit Code Review

Gerrit is a code review and project management tool for Git based projects.

Build Status Maven Central

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.

License

Gerrit is provided under the Apache License 2.0.

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 8 based Gerrit image:

    docker run -p 8080:8080 gerritcodereview/gerrit[:version]-centos8

To run a Ubuntu 20.04 based Gerrit image:

    docker run -p 8080:8080 gerritcodereview/gerrit[:version]-ubuntu20

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