Problem:
Tests were calling `defer setup.Close()` which was interfering with the
library cleanup added in the previous commit. The execution order was:
1. setupTestServer() registers t.Cleanup() with library deletion code
2. Test calls defer setup.Close()
3. Test finishes:
- defer setup.Close() runs FIRST → closes DB pool
- t.Cleanup() runs SECOND → tries to delete libraries but DB is closed!
This prevented "Job Status Test Library" and other test libraries from
being cleaned up, leaving residual data in the database after tests.
Root Cause:
The setupTestServer() function already handles cleanup via t.Cleanup(),
which calls setup.Close() at the end. The explicit defer calls were
redundant and caused the database pool to close before library cleanup
could execute.
Solution:
Removed all 17 occurrences of `defer setup.Close()` from test files:
- worker_test.go: 4 tests
- jobs_test.go: 7 tests
- scan_settings_integration_test.go: 3 tests
- library_browse_test.go: 1 test
- goroutine_leak_test.go: 1 test
- fsnotify_integration_test.go: 1 test
Now setupTestServer()'s t.Cleanup() function properly:
1. Deletes "test" libraries (while DB is still connected)
2. Then calls setup.Close() to close connections
This ensures all test libraries are cleaned up, leaving a clean database
after `make test-integration` completes.
Files changed:
- cmd/server/tests/worker_test.go: Removed 4 defer calls
- cmd/server/tests/jobs_test.go: Removed 7 defer calls
- cmd/server/tests/scan_settings_integration_test.go: Removed 3 defer calls
- cmd/server/tests/library_browse_test.go: Removed 1 defer call
- cmd/server/tests/goroutine_leak_test.go: Removed 1 defer call
- cmd/server/tests/fsnotify_integration_test.go: Removed 1 defer call
- Correct indentation in goroutine leak test setup block
- Align struct field tags in BookMatch and all matching methods for
consistent column-style formatting (media_item_id, bookhoard_uuid,
confidence, match_method)
- Improves code readability and adheres to project indentation guidelines
Critical fixes to prevent goroutine leaks during application shutdown:
1. Sync Queue Processor:
- Changed StartCleanupTask() to return context.CancelFunc
- Modified to accept and watch cancellable context
- Added queue context/cancel to Handler struct
- Created StartBackgroundTasks() method for main handler instance
- Cancel queue processor during shutdown in StopScheduler()
2. Connection Manager:
- Modified StartCleanupTask() to use cancellable context
- Returns cancel function that can be called during shutdown
- Goroutine now properly exits when context is cancelled
3. Handler Lifecycle:
- Added StartBackgroundTasks() to Handler
- Only main handler instance starts background goroutines
- Temporary handler instances (library/sync routes) don't start tasks
- StopScheduler() now properly shuts down all background goroutines
4. Router Integration:
- Updated SetupRoutes to accept queueProcessor parameter
- Main scanner handler starts background tasks after creation
- Library and sync route handlers don't start duplicate tasks
Impact:
- Fixes 2 major goroutine leaks (queue processor + connection cleanup)
- Application now properly shuts down all goroutines on exit
- No more resource leaks from long-running goroutines
- Test added to detect future goroutine regressions
Test: TestGoroutineCleanup verifies background services can be stopped.
