Summary
Introduces a canonical NOTICE template and a manual prek hook to keep all
distribution NOTICE files in sync.
Problem
The repo has 170+ NOTICE files maintained independently. When the ASF header
needs updating (e.g. wording change, year), every file must be touched manually
with no automation to ensure consistency.
Changes
New scripts/ci/license-templates/NOTICE — canonical ASF header for all
standard distributions. This is the single source of truth; all standard
provider/SDK NOTICE files should match it exactly.
New scripts/ci/prek/sync_notice_files.py — manual-stage prek hook that:
Overwrites standard NOTICE files that diverge from the canonical source
For NOTICE files containing a
=======================================================================
separator (vendored-in third-party content: airflow-core, chart,
providers/fab), only updates the copyright year and leaves the custom sections
untouched
Automatically excludes node_modules, .git, .venv, .build
No hardcoded distribution list — presence of the separator is sufficient to
detect custom content
Updated .pre-commit-config.yaml — registers sync-notice-files as a manual
hook
Updated airflow-core/NOTICE, chart/NOTICE, providers/fab/NOTICE — restored
original line break and separator format
(=======================================================================, 71
chars) which had drifted
Usage
Run once whenever the canonical source changes:
```
prek run sync-notice-files --all-files
```
Out of scope
Annual year updates are handled by a separate update-notice-year hook.
