Gerrit Code Review - Command Line Tools

Client

Client commands and hooks can be downloaded via scp, wget or curl from Gerrit’s daemon, and then executed on the client system.

To download a client command or hook, use scp or an http client:

$ scp -p -P 29418 john.doe@review.example.com:bin/gerrit-cherry-pick ~/bin/
$ scp -p -P 29418 john.doe@review.example.com:hooks/commit-msg .git/hooks/

$ curl -Lo ~/bin/gerrit-cherry-pick http://review.example.com/tools/bin/gerrit-cherry-pick
$ curl -Lo .git/hooks/commit-msg http://review.example.com/tools/hooks/commit-msg

For more details on how to determine the correct SSH port number, see Testing Your SSH Connection.

Commands

gerrit-cherry-pick: Download and cherry-pick one or more changes (commits).

Hooks

Client hooks can be installed into a local Git repository, improving the developer experience when working with a Gerrit Code Review server.

commit-msg: Automatically generate Change-Id: tags in commit messages.

Server

Aside from the standard Git server side actions, Gerrit supports several other commands over its internal SSH daemon. As Gerrit does not provide an interactive shell, the commands must be triggered from an ssh client, for example:

  $ ssh -p 29418 review.example.com gerrit ls-projects

For more details on how to determine the correct SSH port number, see Testing Your SSH Connection.

Trace

For executing SSH commands tracing can be enabled by setting the --trace and --trace-id <trace-id> options. It is recommended to use the ID of the issue that is being investigated as trace ID.

  $ ssh -p 29418 review.example.com gerrit create-project --trace --trace-id issue/123 foo/bar

It is also possible to omit the trace ID and get a unique trace ID generated.

  $ ssh -p 29418 review.example.com gerrit create-project --trace foo/bar

Enabling tracing results in additional logs with debug information that are written to the error_log. All logs that correspond to the traced request are associated with the trace ID. The trace ID is printed to the stderr command output:

  TRACE_ID: 1534174322774-7edf2a7b

Given the trace ID an administrator can find the corresponding logs and investigate issues more easily.
