Create a Beta Tag

Require an explicit stable base version in <major>.<minor>[.<patch>] form; treat two components as patch 0. Do not infer it from the branch or package metadata, and do not edit version files while creating the tag.

Prefer release/<major>.<minor>. If that remote branch does not exist, use main only when its workspace version equals the requested base version. Select the next unused positive beta number for that exact base version unless the user provides one. Relay tags are raw SemVer: 0.9.0-beta.1, never v0.9.0-beta.1.

Before the destructive tag push, require explicit approval. Preserve user changes: do not stash, discard, or switch away from a dirty checkout. Fetch the source branch and tags, require HEAD to equal upstream/<source-branch>, and require the workspace version to equal the stable base version. Verify both local and remote tags are absent, create a signed annotated tag, verify it with git tag -v, and push only refs/tags/<tag>. Stop on any failed check; never force-update, replace, or delete tags.

Select and Verify the Source

Use upstream for NVIDIA/NeMo-Relay. The version and optional beta number are user inputs. Validate a supplied number as a positive integer; otherwise derive the next number after fetching tags for the selected source branch.

BASE_VERSION=<major.minor[.patch]>
[[ "$BASE_VERSION" =~ ^[0-9]+\.[0-9]+(\.[0-9]+)?$ ]] || { echo "Error: invalid base version" >&2; exit 1; }
if [[ "$BASE_VERSION" =~ ^[0-9]+\.[0-9]+$ ]]; then BASE_VERSION="$BASE_VERSION.0"; fi
RELEASE_BRANCH="release/$(printf '%s' "$BASE_VERSION" | cut -d. -f1,2)"
SOURCE_BRANCH="$RELEASE_BRANCH"
if git ls-remote --exit-code --heads upstream "refs/heads/$SOURCE_BRANCH" >/dev/null; then
  :
else
  lookup_status=$?
  case "$lookup_status" in
    2) SOURCE_BRANCH=main ;;
    *) echo "Error: release branch lookup failed" >&2; exit "$lookup_status" ;;
  esac
fi
git fetch upstream "$SOURCE_BRANCH" --tags

LAST_BETA="$(git tag --list "${BASE_VERSION}-beta.*" | sed -nE "s/^${BASE_VERSION//./\\.}-beta\.([1-9][0-9]*)$/\\1/p" | sort -n | tail -1)"
BETA_NUMBER="${BETA_NUMBER:-$(( ${LAST_BETA:-0} + 1 ))}"
[[ "$BETA_NUMBER" =~ ^[1-9][0-9]*$ ]]
TAG="${BASE_VERSION}-beta.${BETA_NUMBER}"

From a clean checkout of SOURCE_BRANCH, verify the branch is current, the workspace version matches BASE_VERSION, and the tag is absent locally and on upstream. When SOURCE_BRANCH is main, make the same version check against upstream/main before switching. After the user authorizes the push:

git tag -s -a -m "NVIDIA NeMo Relay ${TAG}" "$TAG" HEAD
git tag -v "$TAG"
git push upstream "refs/tags/$TAG"
