Treat unsaved comment as a DraftInfo entity

This means removing the `UnsavedInfo` type and moving control of unsaved
drafts into the comment model. Before this change unsaved drafts were
just a local state of comment components.

The motivation for this change comes from implementing optimistic
updates. For that we need to be able to go back from SAVING state to
UNSAVED in case of an error. With the current implementation that was
not really possible, or would at least have created a great mess.

The simplification in `gr-comment-thread` and `gr-diff-host` proves that
this change is also desirable for other reasons. It is much easier for
these two components to just consume everything from the model instead
of treating unsaved and saved drafts separately.

One challenge was how to deal with the `id` of a draft. The server sets
the `id` once it was saved, but until then we still need some kind of
identification, so for unsaved drafts we create a `client_id` and use
that for identifying the draft, even after it has been saved.

The type system for `CommentInfo` and `DraftInfo` has also cleaned up a
bit. Sorry for the noise of replacing some `PathToCommentsInfoMap` by
`{[path: string]: CommentInfo[]}` etc.

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.
