- Fixed incorrect init_connections() call in test_etcp_simple_traffic.c (was calling server_instance instead of client_instance)
- Fixed double free in timeout_heap_pop() when handling deleted elements
- Enhanced NULL pointer safety in uasync_print_resources() by removing complex heap manipulation
- Added debug logging to timeout_heap_pop() for better error tracking
Test results: test_etcp_simple_traffic now passes without double free errors
✅ Fixed critical segmentation fault (SIGABRT) in test_etcp_two_instances
✅ Added comprehensive timer debug logging with DEBUG_CATEGORY_TIMERS
✅ Created uasync_print_resources() function for resource diagnostics
✅ Created utun_instance_diagnose_leaks() function for leak analysis
✅ Fixed cleanup order - cancel timers before destroying uasync instances
✅ Fixed timer cancellation to properly update counters
✅ Fixed socket cleanup to unregister from uasync before destruction
✅ Added detailed diagnostic output for memory leak tracking
✅ All tests now pass without crashes
Key fixes:
- Fixed use-after-free in test cleanup sequence
- Added proper timer leak detection and cleanup
- Enhanced debug capabilities for future debugging
- Fixed ETCP socket cleanup to prevent resource leaks
The test_etcp_two_instances now runs successfully without segmentation faults.
- Устранена критическая race condition: callback больше не пытается отменить уже удаленный waiter
- Упрощена логика управления waiter'ами: callback просто очищает указатель и отправляет следующий пакет
- Добавлена статистика pacing для анализа производительности
- Оптимизирована производительность: убраны лишние отладочные сообщения в hot path
- Улучшена обработка NULL от queue_wait_threshold: разделены случаи очередь пуста и ошибка
- Добавлена условная компиляция для отладочных сообщений в ll_queue.c
- Pacing теперь работает быстро при нулевых очередях: callback вызывается немедленно при опустошении
- Implement queue_wait_threshold() with automatic waiter checking in ll_queue
- Add pkt_normalizer_flush() to force buffer sending
- Enhance test suite with async wait tests, fragmentation verification, and buffer flush tests
- Fix test edge cases by flushing packer buffer between subtests
- Improve test reliability with increased iteration limits and while loop processing
- Add connection module for secure UDP communication with ECC/AES-CCM cryptography
- Move all test files to tests/ directory
- Update Makefile to build tests in tests/ directory
- Add fragment reassembly timeout mechanism (500ms default)
- Add error count API (pkt_normalizer_get_error_count, pkt_normalizer_reset_error_count)
- Enhance error handling with timeout callbacks
- Add comprehensive stress tests and edge case tests
- Update .gitignore for build artifacts
