Archive git repositories before deletion: - Create tar.gz archives in .archive/<npub>/<identifier>-<timestamp>.tar.gz - Store metadata JSON with deletion info and expiry timestamp - Archive git data BEFORE moving events to holding database - Uses flate2 for gzip compression and tar crate for archive creation - Graceful error handling (deletion continues even if archival fails) Background cleanup task: - Spawned as tokio task in main.rs - Runs on startup (catch-up for offline periods) - Runs at configurable interval (default: 24 hours) - Deletes expired events from holding database - Removes archive tar.gz files and metadata JSON - Tracks disk space reclamation in CleanupResult Archive metadata structure: - Deletion timestamp and event ID - Maintainer pubkey and repository identifier - Archive file path for cleanup coordination - Expiry timestamp (deletion_ts + retention_secs) Tests: 21 tests covering: - Archive unit tests (8 tests) - Archive creation and compression - Extraction and integrity verification - Metadata serialization - Error handling (missing directories, corrupt data) - Cleanup unit tests (5 tests) - Expired event deletion - Archive file cleanup - Missing file handling - CleanupResult statistics - Integration tests (8 tests) - End-to-end archival workflow - Background cleanup with short retention (5 seconds) - Startup cleanup (pre-existing expired data) - Disk space reclamation verification - Multiple expired events - Preservation of non-expired events
Reference
Information-oriented documentation - Technical details and specifications.
What Is Reference Documentation?
Reference documentation provides factual, technical information that you look up when needed.
Characteristics:
- ✅ Information-oriented (facts and data)
- ✅ Comprehensive and accurate
- ✅ Structured for lookup
- ✅ Dry and to-the-point
- ✅ Maintained as code changes
Not reference:
- ❌ Learning materials (those are Tutorials)
- ❌ Problem-solving guides (those are How-To)
- ❌ Conceptual explanations (those are Explanation)
