Release management

Release numbering

The Forgejo release numbers are composed of the Gitea release number followed by a dash and a serial number. For instance:

• Gitea v1.18.0 will be Forgejo v1.18.0-0, v1.18.0-1, etc

The Gitea release candidates are suffixed with -rcN which is handled as a special case for packaging: although X.Y.Z is lexicographically lower than X.Y.Z-rc1 is is considered greater. The Forgejo serial number must therefore be inserted before the -rcN suffix to preserve the expected version ordering.

• Gitea v1.18.0-rc0 will be Forgejo v1.18.0-0-rc0, v1.18.0-1-rc0
• Gitea v1.18.0-rc1 will be Forgejo v1.18.0-2-rc1, v1.18.0-3-rc1, v1.18.0-4-rc1
• Gitea v1.18.0 will be Forgejo v1.18.0-5, v1.18.0-6, v1.18.0-7
• etc.

Because Forgejo is a soft fork of Gitea, it must retain the same release numbering scheme to be compatible with libraries and tools that depend on it. For instance, the tea CLI or the Gitea SDK will behave differently depending on the server version they connect to. If Forgejo had a different numbering scheme, it would no longer be compatible with the Gitea ecosystem.

From a Semantic Versioning standpoint, all Forgejo releases are pre-releases because they are suffixed with a dash. They are syntactically correct but do not comply with the Semantic Versioning recommendations. Gitea is not compliant either and as long as Forgejo is a soft fork, it inherits this problem.

Release process

Integration

• Reset the vX.Y/forgejo branch to the Gitea tag vX.Y.Z
• Merge all feature branches into the vX.Y/forgejo branch

Testing

When Forgejo is released, artefacts (packages, binaries, etc.) are first published by the CI/CD pipelines in the https://codeberg.org/forgejo-integration organization, to be downloaded and verified to work. When modifying the CI/CD pipelines, there is a chance that these verification steps fail and that the published artefacts override previous ones or worse. During this debugging phase, a fork of Forgejo must be used.

• Push the vX.Y.Z-N tag to a Forgejo fork (e.g. https://codeberg.org/someuser/forgejo)
• Verify the release is published in https://codeberg.org/forgejo-integration
• Verify the release is published in https://codeberg.org/someuser

Publication

• Push the vX.Y.Z-N tag to https://codeberg.org/forgejo/forgejo
• Binaries are built, signed and uploaded by the CI.
• Container images are built and uploaded by the CI.

Website update

• Restart the last CI build at https://codeberg.org/forgejo/website/src/branch/main/
• Verify https://forgejo.org/download/ points to the expected release
• Manually try the instructions to work

Release signing keys management

A GPG master key with no expiration date is created and shared with members of the Owners team via encrypted email. A subkey with a one year expiration date is created and stored in the secrets repository, to be used by the CI pipeline. The public master key is stored in the secrets repository and published where relevant.

Master key creation

• gpg --expert --full-generate-key
• key type: ECC and ECC option with Curve 25519 as curve
• no expiration
• id: Forgejo Releases contact@forgejo.org
• gpg --export-secret-keys --armor EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 and send via encrypted email to Owners
• gpg --export --armor EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 > release-team-gpg.pub
• commit to the secret repository

Subkey creation and renewal

• gpg --expert --edit-key EB114F5E6C0DC2BCDD183550A4B61A2DC5923710
• addkey
• key type: ECC (signature only)
• key validity: one year
• create an issue to schedule the renewal

2023

• gpg --export --armor F7CBF02094E7665E17ED6C44E381BF3E50D53707 > 2023-release-team-gpg.pub
• gpg --export-secret-keys --armor F7CBF02094E7665E17ED6C44E381BF3E50D53707 > 2023-release-team-gpg
• commit to the secrets repository
• renewal issue https://codeberg.org/forgejo/forgejo/issues/58

CI configuration

In the Woodpecker CI configuration the following secrets must be set:

• releaseteamgpg is the secret GPG key used to sign the releases
• releaseteamuser is the user name to authenticate with the Forgejo API and publish the releases
• releaseteamtoken is the token to authenticate releaseteamuser with the Forgejo API and publish the releases
• domain is codeberg.org

Users, organizations and repositories

Shared user: release-team

The release-team user publishes and signs all releases. The associated email is mailto:release@forgejo.org.

The public GPG key used to sign the releases is EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 Forgejo Releases <release@forgejo.org>

Integration organization

The https://codeberg.org/forgejo-integration organization is dedicated to integration testing. Its purpose is to ensure all artefacts can effectively be published and retrieved by the CI/CD pipelines. The release-team user as well as all Forgejo contributors working on the CI/CD pipeline should be owners of the forgejo-integration organization. Assuming someuser is such a user, they can use this organization to verify a modified CI/CD pipeline behaves as expected before actually trying to publish anything for real at https://codeberg.org/forgejo.

• Modify files in the .woodpecker directory
• Set a tag (e.g. v10.0.0)
• Push the tag to https://codeberg.org/someouser/forgejo
• After the CI/CD pipeline completes the artefacts (release, package, etc.) must be available and identical at https://codeberg.org/someouser/forgejo and https://codeberg.org/forgejo-integration/forgejo
