# Netlify configuration for Superset documentation
# This enables automatic deploy previews for PRs that modify docs

  base = "docs"
  # Build command for Docusaurus
  command = "yarn install && yarn build"
  # Output directory (relative to base)
  publish = "build"
  # Skip builds when no docs changes (exit 0 = skip, non-zero = build).
  # Checks for changes in docs/ and README.md (which gets pulled into docs).
  #
  # $CACHED_COMMIT_REF is the last *deployed* commit; it is set on incremental
  # builds (notably the master production deploy) and empty on a context's
  # first build (every deploy preview). The production path diffs against it
  # and skips correctly.
  #
  # Deploy previews need different handling: Netlify checks out a *merge*
  # commit, so $COMMIT_REF (the PR head SHA) is frequently not resolvable in
  # the clone, and on a shallow clone `git merge-base` can fail too -- so the
  # previous logic fell through to a build on every PR, even non-docs ones.
  # Instead, always diff the checked-out HEAD against its merge-base with
  # master, deepening the shallow clone until that merge-base resolves. If it
  # genuinely can't be determined, exit non-zero to build (fail safe).
