Day47 - Multi-Message TX Queue

Goal

Upgrade the Day46 single-message TX buffer into a multi-message TX queue.

Implemented

• tx_msg
• tx_queue
• tx_queue_push()
• tx_queue_front()
• tx_queue_pop()
• tx_queue_clear()
• EPOLLOUT drain loop
• client cleanup with pending TX messages released

Test

./mytcp_server
bash test_epoll_txq.sh

Result

• Multi-client test passed.
• Burst TX queue behavior worked.
• Partial recv behavior was observed.
• TCP stream parsing is required for application-level message boundaries.
