SGLang Cherry-Pick

Trigger .github/workflows/bot-cherry-pick.yml for each PR in a list, then monitor the resulting workflow runs and report per-PR success/failure with links to the created cherry-pick PRs (or the failure reason).

Slash Command

/sglang-cherrypick <target_branch> <pr1> [pr2 pr3 ...]

Examples:

• /sglang-cherrypick release/v0.5.7 25956 25958 25987
• /sglang-cherrypick release/v0.5.7 25956,25958,25987 (comma-separated also accepted)

Arguments

• target_branch (required): Release branch in the form release/vX.Y or release/vX.Y.Z. Must already exist on origin (i.e., sgl-project/sglang).
• pr_numbers (required, one or more): Merged PR numbers to cherry-pick. Each must be a positive integer.

Repository

Always targets the upstream repo sgl-project/sglang. The workflow's job guard (if: github.repository == 'sgl-project/sglang') means triggering it on a fork is a no-op.

Workflow

Step 1 — Validate arguments

Fail fast before triggering anything.

# target branch shape (matches the workflow's own validator)
[[ "$TARGET_BRANCH" =~ ^release/v[0-9]+\.[0-9]+(\.[0-9]+)?$ ]] || die "Invalid target_branch"

# branch exists on upstream
gh api "repos/sgl-project/sglang/branches/$TARGET_BRANCH" --jq '.name' >/dev/null || die "Branch not found"

# each PR is numeric, exists, MERGED, and has a recorded merge commit
declare -A PR_TO_SHA=()
declare -A PR_TO_TITLE=()
for PR in "${PRS[@]}"; do
  [[ "$PR" =~ ^[0-9]+$ ]] || die "PR '$PR' is not a positive integer"
  PR_JSON=$(gh pr view "$PR" --repo sgl-project/sglang --json state,mergeCommit,title) \
    || die "PR #$PR not found"
  STATE=$(jq -r .state <<<"$PR_JSON")
  [[ "$STATE" == "MERGED" ]] || die "PR #$PR is not MERGED (state=$STATE)"
  SHA=$(jq -r '.mergeCommit.oid // empty' <<<"$PR_JSON")
  [[ -n "$SHA" ]] || die "PR #$PR has no merge commit recorded"
  PR_TO_SHA[$PR]="$SHA"
  PR_TO_TITLE[$PR]=$(jq -r .title <<<"$PR_JSON")
done

Report any failures and stop — do not trigger partial batches.
