Setting up environment
======================

This chapter is based on the `Git Guide <https://docs.releng.linuxfoundation.org/en/latest/git.html>`_
and the `Gerrit Guide <https://docs.releng.linuxfoundation.org/en/latest/gerrit.html>`_
in the Linux Foundation Releng Documentation.

Prerequisites
~~~~~~~~~~~~~

Before you start, you should have an LFID account (sign up
`here <https://identity.linuxfoundation.org/>`_).

Installing git
~~~~~~~~~~~~~~

1. Install Git.

   For Debian based systems:

   .. code-block:: bash

      sudo apt-get install git -y


   For rpm based systems:

   .. code-block:: bash

      sudo dnf install git -y


   For MacOS systems, install `homebrew <http://brew.sh>`_ and install Git

   .. code-block:: bash

      brew install git

.. note:: For more information on git, see the `Git Guide <https://docs.releng.linuxfoundation.org/en/latest/git.html>`_ in the Linux Foundation Releng Documentation.

Configure Git
~~~~~~~~~~~~~

1. Set the author name or email used to sign off a commit with the following commands.

.. code-block:: bash

   git config --local user.name "Your Name"
   git config --local user.email yourname@example.com

.. note:: Your name and e-mail address (including capitalization) must match the one you entered when creating your LFID account.

2. Optionally, change the Git commit editor to your preferred editor, for example, vim.

.. code-block:: bash

   git config --global core.editor "vim"

Installing git-review
~~~~~~~~~~~~~~~~~~~~~

1. Install git-review.

.. code-block:: bash

    pip install git-review

.. note:: If you don’t have pip installed already, follow the `installation documentation <https://pip.pypa.io/en/stable/installation/>`_ for pip.

Setting up gerrit
~~~~~~~~~~~~~~~~~

Setting SSH keys
----------------

1. Generate SSH keys.

    For OpenSSH 8.7 or older versions:

    .. code-block:: bash

       ssh-keygen -t rsa

    For OpenSSH 8.8 or later versions, either use ed25519 or ECDSA algorithm to generate ssh keys:

    .. code-block:: bash

        ssh-keygen -t ed25519

    or

    .. code-block:: bash

        ssh-keygen -t ECDSA

    .. note:: OpenSSH 8.8+ disables RSA signatures using the SHA-1 hash algorithm by default, which may cause authentication problem when pull/push code. You can either specify the encrypt algorithm or re-enable the RSA/SHA1 in ~/.ssh/config file to solve the issue. For more information, please refer to `OpenSSH Release Notes <https://www.openssh.com/releasenotes.html>`_.

    Your public key is now available as .ssh/id_rsa.pub or .ssh/id_ed25519.pub or .ssh/id_ecdsa.pub under .ssh folder.

2. Print the generated key to the terminal and copy it.

.. code-block:: bash

    cat .ssh/id_rsa.pub

3. On the project gerrit page, go to Settings.
