# dep_freshness_changed.sh - run the dependency-freshness gate on the
|
|
# manifests THIS BRANCH changed, not on every manifest pre-commit hands over.
|
|
#
|
|
# Why: `pre-commit run --all-files` (the todoImplementer runner's check) passes
|
|
# every manifest in the monorepo, so one feature branch went red on 43 stale
|
|
# pins in 12 projects it never touched. Scoping to changed manifests makes the
|
|
# hook answer "did this change leave a stale pin?". The repo-wide question
|
|
# stays with CI (.github/workflows/dependency-freshness.yml: --all --strict).
|
|
#
|
|
# "Changed" = differs from the merge-base with $DEP_FRESHNESS_BASE (default
|
|
# main, then origin/main), working tree included, plus untracked files.
|
|
# A plain commit only passes staged files, which are all "changed", so normal
|
|
# commits behave exactly as before.
|
|
#
|
|
# Fails closed: no resolvable base, or a cwd that is not the repo root (so
|
|
# paths cannot be compared), forwards every file unfiltered.
|
|
#
|
|
# Usage: scripts/dep_freshness_changed.sh <file>...
|
|
# Env: DEP_FRESHNESS_GATE gate to call (default: check_dependency_freshness.sh
|
|
# next to this script); DEP_FRESHNESS_BASE (main)
