Create PR
^^^^^^^^^

.. code-block::
git checkout -b <owner>/release-<X.Y>
scripts/release.sh <X.Y>~rc1
git push -u origin <owner>/release-<X.Y>
firefox https://github.com/gramineproject/gramine/pull/new/<owner>/release-<X.Y>
Then set the PR on reviewable.io to be reviewed commit-by-commit.

Update version in PR
^^^^^^^^^^^^^^^^^^^^

.. code-block::
git reset --hard HEAD~
scripts/release.sh X.Y~rcN
git push --force
Tag
^^^

.. code-block::
git tag -m "Gramine <X.Y>" v<X.Y> HEAD~
git push v<X.Y>
Code signing
------------

.. note::

“Code signing” is not to be confused with “signing off” your commits.

“Signing off” is a |~| legal device for a sort of signature by which you
assert that you are holding copyrights to the code you're submitting (or
your're authorized by copyright holder to submit the code). “Signing off” is
done by writing ``Signed-off-by:`` line to the commit message (maybe using
:command:`git commit -s`) and does not carry a separate cryptographic
signature. For details, please read :doc:`DCO/index`.

“Code signing” refers to the process of cryptographically siging your
contributions (commits and tags), so other people are able to mathematically
prove that the contribution came from the holder of a |~| particular
cryptographic key. It has no legal meaning. It can be done using
:command:`git commit -S` or by configuring :program:`git` (see below).

Generating key
^^^^^^^^^^^^^^
First, you need to generate you key using :program:`gpg`. The key needs to be
"sign only"! Otherwise, if you also add encrypt capability, people will add your
key to their :abbr:`MUA (Mail User Agent)`\ s and will encrypt e-mail messages
to you using code signing key. This is not desired, the key generated for the
purpose of code signing should not be used in any other context (e.g. e-mail or
singing code in other projects).

In user ID, please write your name and comment saying that the key is meant for
code signing in this project.

The key needs to be RSA (at least 3072 to match overall security level in SGX)
or Curve25519. 25519 keys are preferred, because they are smaller and faster to
use. In some versions of :program:`gpg` you need to use ``--full-gen-key
--expert`` to be able to choose ECC keys.

Is this correct? (y/N) y
GnuPG needs to construct a user ID to identify your key.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

.. yes, this is actual log from generating my own key!
Submitting key to GitHub
^^^^^^^^^^^^^^^^^^^^^^^^

https://docs.github.com/en/authentication/managing-commit-signature-verification/adding-a-gpg-key-to-your-github-account#adding-a-gpg-key

Setting up git
^^^^^^^^^^^^^^

*(Substitute key ID for your own key. The following example matches key ID from
the example generation listing.)*

.. code-block:: sh
git config --global commit.gpgsign true
git config --global user.signingkey 9C4D27D9157EF771A4283926044D9664E7A77E16
If you are using Split GPG feature of Qubes OS
(https://www.qubes-os.org/doc/split-gpg/#using-git-with-split-gpg):

.. code-block:: sh
git config --global gpg.program qubes-gpg-client-wrapper
and remember to set ``QUBES_GPG_DOMAIN`` envrionment variable in your shell
config file.
