Tux-Dock Development Log

0.1.1-beta

This release establishes the first beta-quality Docker integration and TUI workflow.

Docker integration

• Added direct Docker Engine API access through /var/run/docker.sock.
• Added startup Docker preflight using GET /_ping before launching the TUI.
• Added synchronous initial container and image loading.
• Added asynchronous cache refreshes after mutations and interactive sessions.
• Preserved cached state when a refresh fails.
• Added structured container/image JSON mapping with exited-container support.

Process execution

• Replaced system() and popen() with a fork/exec process runner.
• Added captured stdout/stderr and inherited terminal I/O modes.
• Kept direct CLI execution for interactive terminal handoffs.

Reliability

• Added HTTP response parsing for Content-Length, chunked transfer, and bodyless responses.
• Added robust handling for Docker 204 and idempotent 304 responses.
• Added tri-state stop polling: stopped, running, and unknown.
• Added bounded stop retries after transport timeouts.
• Stop completion now refreshes cached state before showing the result modal.

TUI

• Replaced the persistent status panel with a centered actions panel.
• Added busy-operation modals with spinner feedback.
• Blocked input during long-running Docker operations.
• Added structured, scrollable container and image list dialogs.

Tests

• Added HTTP response parser tests.
• Added container JSON mapping tests.
• Added operation-state tests.
• Added stop polling and timeout-sequence regression tests.
