# Decide which release an automatic run publishes, out of the two release-please invocations in the prepare job.
|
|
#
|
|
# FIRST_* comes from the invocation that recovers releases for pull requests already merged when the run started, which is the one that fires when a human merged the release pull request by hand instead of letting land-release-pr.sh do it. SECOND_* comes from the invocation after this run merged the pull request itself. On any given push at most one of them normally reports a release. The invocation between them only refreshes the pull request and creates no release, so it is not consulted here.
|
|
#
|
|
# When both do report one, the push carried a merged release pull request and further releasable commits at once. The second release is the newer version and supersedes the first, so it is the one that gets built; the first remains a stable draft for a manual dispatch to pick up. The selected release also remains a stable draft: publish-release.sh creates a separate beta prerelease for the automatic artifact.
|
|
#
|
|
# The manual path gets its immutability guarantees from validate-draft-release.sh. Nothing validates release-please's own outputs, so the same two invariants are checked here: the commit is a full SHA rather than a branch name, and the tag agrees with the version.
|
|
#
|
|
# Requires FIRST_CREATED, FIRST_TAG, FIRST_VERSION, FIRST_SHA and the matching SECOND_* values.
|
|
# Writes release_created, tag_name, version and target_sha to GITHUB_OUTPUT.
