| # Description: |
| # Verify redaction works as expected for various scenarios. |
| # |
| # Strategy: |
| # 1. An unmodified file does not get redacted at all. |
| # 2. Empty redaction list redacts everything. |
| # 3. A file removed in the clone redacts the whole file. |
| # 4. A file moved in the clone does not redact the file. |
| # 5. A copied, then removed file in the clone redacts the whole file. |
| # 6. Overwriting a file with identical contents redacts the file. |
| # 7. A partially modified block redacts the entire block. |
| # 8. Only overlapping areas of modified ranges are redacted. |
| # 9. Send from the root dataset of a pool work correctly. |
