✨ Added

Comprehensive Go Test Suite (2026-01-13)

  • Test Coverage: Achieved 30.0% test coverage (up from 12.5%)
  • Test Files:
    • uploader_coverage_test.go (766 lines) - Rate limiting, gallery operations, HTTP workflows
    • uploader_helpers_test.go (448 lines) - Helper functions, concurrent access, edge cases
    • uploader_utils_test.go (452 lines) - JSON parsing, template substitution, benchmarks
    • uploader_additional_test.go (329 lines) - Job handling, HTTP requests, concurrency
  • Total: 1,995 lines of comprehensive test code

    • HTTP request handling with mock servers
    • Edge cases and error conditions
    • Benchmark tests for performance tracking

Complete Graceful Shutdown System (2026-01-13)

A comprehensive two-layer graceful shutdown implementation for both application and sidecar:

Go Sidecar Layer (uploader.go):

  • Signal Handling: Listen for SIGINT and SIGTERM OS signals
  • Worker Management: sync.WaitGroup tracks all worker goroutines
  • Coordinated Shutdown:
    • Stop accepting new jobs immediately on shutdown signal
    • Close job queue to signal workers
    • Wait for all in-flight jobs to complete
    • Clean resource cleanup and logging
  • EOF Handling: Gracefully handle stdin closure (normal termination)

Python Application Layer (main.py, modules/ui/main_window.py, modules/sidecar.py):

  • Window close event handling via WM_DELETE_WINDOW protocol handler
  • File > Exit menu performs graceful shutdown
  • Signal handlers for SIGINT (Ctrl+C) and SIGTERM in main.py
  • Component-level shutdown methods:
    • AutoPoster.stop() - Stops forum posting thread with 3-second timeout
    • RenameWorker.stop() - Stops gallery rename worker with 2-second timeout
    • UploadManager.shutdown() - Unregisters event listeners and cleans up threads
    • SidecarBridge.shutdown() - Gracefully terminates Go sidecar process
      • Closes stdin to signal exit
      • Waits 5 seconds for graceful termination
      • Force kills if necessary (SIGTERM → SIGKILL)
  • Upload cancellation - In-progress uploads stopped cleanly via cancel_event
  • ThreadPoolExecutor cleanup - Thumbnail executor properly shut down
  • Resource cleanup:
    • All background threads properly joined with timeouts
    • Event queues unregistered from sidecar bridge
    • Go subprocess terminated cleanly
    • Log window closed if open

Combined Benefits:

  • No job loss during shutdown from either application exit or system signal
  • Uploads complete before exit
  • Container and systemd friendly
  • No orphaned goroutines or threads
  • Clean exit codes
  • Fast exit (worst case ~12 seconds with all timeouts)
  • Prevents resource leaks (threads, processes, file handles)
  • Ensures data integrity (no partial writes)
  • Cross-platform support (Windows, Linux, macOS)
