Introduce @DynamicItem.Final for immutable bindings

In some cases plugins would like to expose their API to other plugins,
for example to give access to internal state or to programatically
modify its configuration.

This can be potentially done currently with the usage of DynamicItem,
but that doesn't guarantee that the implementation will not be
overwritten by other plugins.
Also, one plugin may have specific expectations of where the
implementation of those interfaces must be found and
therefore exposing that constraint to Gerrit plugin load so that
only the allowed plugin is accepted for binding that item.

Introduce the @DynamicItem.Final annotation that, once assigned to a
type, requires the type to be bound at most once.

Any attempt to re-bind a DynamicItem.Final twice or from a plugin
which is not the expected one, would result in a Guice
ProvisionException.

Example:

@DynamicItem.Final(implementedByPlugin="foo-plugin")
public interface FooInterface {
    String fooApi(String param);
}

Bug: Issue 338786480
Release-Notes: Introduce @DynamicItem.Final for allowing immutable dynamic bindings of interfaces to implementations in other plugins.

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.
