ReleaseProcess

This page is a work in progress.

= Manual Release Process Notes = Documenting the steps taken todo a release manually, in hopes that it can be automated.

Cross-referencing
Cherry picking, using the -xs flags, automatically adds a cross reference, for example

commit bc21cf1f9ca25dd3efcbc9806cee4f6c1726a905 Author: Marcus Müller  Date:  Sun Aug 15 18:54:10 2021 +0200 audio/jack: to_string is no longer part of boost:: NS, instead use std:: Signed-off-by: Marcus Müller  (cherry picked from commit 883315208853121a8dfa68ae9c2f74400acd5ac5) Signed-off-by: Jeff Long 

For other commits, add cross references to Git commits only, not to PRs. The git repo should stand on its own. At the very least, explain how a commit relates to any work on the master branch.

Backported PRs should reference the original PRs like this Backport #1234 at the bottom of the description.

Change freeze
About 2-3 weeks before release. This is informal. Accept only critical or very low risk changes at this point.

Announce
Mention on the Development and General Chat channels on Matrix. At this point, the mailing list is more for communicating with users than with core developers, so announcements there would not be useful, and could result in solicitation of extra PRs exactly when we are not going to consider them.

RC plan
About 1 week before release.

Changelog
Date and version

Release commit

 * Change CMakeLists.txt to MAJOR.API.ABI.PATCH. If a release candidate, PATCH `0-rc1` format to help with sort order. For final version, PATCH is `0`
 * Create PR with this change, title formatted like "Release v3.8.3.0-rc1"
 * Merge release PR
 * Sync local checkout for later comparison step

Version change for continuation
Skip if this is a RC version. The branch will stay linear until the final version is released.

CMakeLists.txt
Change CMakeLists.txt to MAJOR.API.ABI.git

Sign tag
Tagging is done against a git clone of. Recommend keeping this in a separate directory, to avoid inadvertent pushes directly to the gnuradio repo. git checkout  git tag -u info@gnuradio.org  -m '' git tag -v  git push origin  This will use the latest signing key associated with info@gnuradio.org.

Release

 * In Github, go to code, branch, and then release list (or tags, then hit releases)
 * Draft a new release
 * Select branch and enter release version from commit as a tag
 * Title same as commit: "Release v..."
 * Publish
 * Github creates a tar.gz and a zip
 * Download these files immediately
 * For 3.8, create variants with a -with-volk-X.Y.Z suffix
 * Check out volk using
 * Create tar.gz and zip files
 * Volk versions
 * Previous to 3.8.3.0, it was included in all releases
 * 3.8.3.0 -with-volk variant includes v2.0.0
 * 3.8.3.1 and later include both v2.0.0 and latest-stable variants
 * Fedora requested we continue to include Volk for 3.8 to keep packaging consistent

Verify or create valid signing key
The GPG key includes a signing subkey, which is used to sign releases. The master key is used only for certifying subkeys.

Currently, the signing subkey expiration date is extended a year at a time, as long as there are no personnel changes and the key remains secure.

Download tar.gz and zip
If not done in release step

Verify archives

 * Unpack each archive
 * Diff against existing git checkout to verify, e.g., with meld. Expect minor differences due to git ignored files (e.g., `__pycache__`, `.vscode`)
 * Keep the tar and zip files locally for a little while in case something comes up

Sign archives

 * Create detacted signatures: `gpg --detach-sign --armor -u info@gnuradio.org filename`
 * Verify signatures: `gpg --verify filename.asc`
 * Keep the signatures locally for a little while in case something comes up

Upload signatures and public key

 * On Github release page, edit release
 * Click "attach binaries" or drag/drop files
 * ...tar.gz.asc
 * ...zip.asc
 * gnuradio-software-signing-key.asc
 * Note that the signing key should also be somewhere else where people can verify it
