Tests: - tombstone_purge_test_short.rs: Quick validation (~10 min) with 5-min interval - tombstone_purge_test.rs: Full test (~65 min) with 1-hour CBS minimum interval Test scenario: 1. Create document in accessible channel and replicate 2. Delete document (creating tombstone) 3. Purge tombstone from Sync Gateway 4. Configure CBS metadata purge interval 5. Wait for purge interval + margin 6. Compact CBS and SGW 7. Verify tombstone no longer exists in CBS 8. Re-create document with same ID 9. Verify it's treated as new (flags=0) not deleted (flags=1) The tests validate whether tombstones can be completely purged from CBS and SGW such that re-creating a document with the same ID is treated as a brand new document.

charset=UTF-8 Content-Transfer-Encoding: 8bit Update tombstone_purge_test.rs to use the new automated test infrastructure with Docker management and structured reporting. Changes to tombstone_purge_test.rs: - Add git status validation before test - Automatically rebuild Docker environment with correct config - Integrate TestReporter for structured output - Add checkpoints at each major step with _sync xattr capture - Generate comprehensive report in test_results/ directory - Note: Purge interval no longer set during test (STEP 4) It's now configured at bucket creation via Docker setup New example: - test_with_reporting.rs: Minimal example demonstrating the reporting infrastructure without long waits README updates: - Document automated test infrastructure features - Add check_cbs_config and tombstone_quick_check examples - Explain test report structure and contents - Update tombstone_purge_test description with automation details The test now ensures clean, reproducible runs with complete documentation for Couchbase support analysis. šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- examples/README.md | 62 +++++++++- examples/test_with_reporting.rs | 163 ++++++++++++++++++++++++++ examples/tombstone_purge_test.rs | 190 ++++++++++++++++++++++--------- 3 files changed, 359 insertions(+), 56 deletions(-) create mode 100644 examples/test_with_reporting.rs diff --git a/examples/README.md b/examples/README.md index 75273f3..677cdfa 100644 --- a/examples/README.md +++ b/examples/README.md @@ -42,10 +42,55 @@ Update the file `docker-conf/db-config.json` and run $ curl -XPUT -v "http://localhost:4985/my-db/" -H 'Content-Type: application/json' --data-binary @docker-conf/db-config.json ``` +## Automated Test Infrastructure + +The long-running tests (`tombstone_purge_test` and `tombstone_purge_test_short`) now include: + +- **Automatic Docker environment management**: Stops, rebuilds, and starts containers with correct configuration +- **Git validation**: Ensures no uncommitted changes before running +- **Structured reporting**: Generates comprehensive test reports in `test_results/` directory + +### Test Reports + +Each test run generates a timestamped report directory containing: +- `README.md`: Executive summary with test checkpoints and findings +- `metadata.json`: Test metadata, commit SHA, GitHub link +- `tombstone_states.json`: Full `_sync` xattr content at each checkpoint +- `test_output.log`: Complete console output +- `cbs_logs.log`: Couchbase Server container logs +- `sgw_logs.log`: Sync Gateway container logs + +**Example report path**: `test_results/test_run_2025-11-01_08-00-00_8db78d6/` + ## Running an example ### Available examples +#### `check_cbs_config` +Utility to verify Couchbase Server bucket configuration, especially metadata purge interval. + +**Runtime: Instant** + +```shell +$ cargo run --features=enterprise --example check_cbs_config +``` + +Expected output: +``` +āœ“ CBS metadata purge interval (at purgeInterval): 0.04 + = 0.04 days (~1.0 hours, ~58 minutes) +``` + +#### `tombstone_quick_check` +Rapid validation test for tombstone detection via XATTRs.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implement sync function logic to detect and handle documents that resurrect after their tombstones have expired (BC-994 scenario). Logic: - If document arrives without oldDoc (!oldDoc) AND has updatedAt field - Check if updatedAt is older than 1 hour (test value, production uses 60 days) - If YES: Route to "soft_deleted" channel + set TTL to 5 minutes - This triggers auto-purge in cblite (document removed from accessible channels) - TTL ensures cleanup from central after 5 minutes Test parameters (adapted for rapid testing): - Cutoff: 1 hour (vs 60 days in production) - TTL: 5 minutes (vs 6 months in production) This tests the complete flow: 1. Document older than cutoff resurre cts from cblite 2. Sync function routes to soft_deleted 3. Auto-purge removes from cblite (not in user channels) 4.

charset=UTF-8 Content-Transfer-Encoding: 8bit Create comprehensive test to validate the complete soft_delete flow when documents resurrect after central tombstone expiry. Test scenario (~75 minutes): 1. Create doc with updatedAt=NOW, replicate to central, STOP replication 2. Delete doc from CENTRAL only (doc remains in cblite) 3. Wait 65 minutes (doc's updatedAt becomes > 1 hour old) 4. Compact CBS + SGW to purge central tombstone 5. Restart replication with RESET CHECKPOINT - Cblite pushes doc1 back to central (resurrection) - Sync function detects updatedAt > 1h cutoff - Routes to "soft_deleted" channel + sets 5-min TTL 6. Verify auto-purge in cblite (doc removed, user has no access to soft_deleted) 7. Wait 6 minutes for TTL expiry 8. Compact CBS + SGW 9. Verify doc purged from central (TTL expired) Features: - Uses automated test infrastructure (Docker management, reporting) - Creates doc with updatedAt field for sync function logic - Tests complete BC-994 flow from resurrection to final purge - Non-blocking checks (logs warnings instead of panics) - Captures full state at each checkpoint This validates the billeo-engine PR #7672 soft_delete logic adapted for testing with 1-hour cutoff and 5-minute TTL. šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- examples/tombstone_resurrection_test.rs | 381 ++++++++++++++++++++++++ 1 file changed, 381 insertions(+) create mode 100644 examples/tombstone_resurrection_test.rs diff --git a/examples/tombstone_resurrection_test.rs b/examples/tombstone_resurrection_test.rs new file mode 100644 index 0000000..5dc82f4 --- /dev/null +++ b/examples/tombstone_resurrection_test.rs @@ -0,0 +1,381 @@ +mod utils;
