ConnectBox Master Changes Log

This file tracks the architecture changes, thinking process, and code refactors made to the ConnectBox system.

1. PxUSBm.py Refactor & Modularization (Completed)

Goal: Deconstruct the monolithic PxUSBm.py script into single-responsibility, event-driven scripts. Changes Made:

  • Created first-boot-expand.py to handle initial filesystem expansion, triggered by a one-shot systemd service (first-boot-expand.service).
  • Created usb_mounter.py triggered natively by udev rules (99-usb-automount.rules) to handle USB insertion events instead of using a constant polling loop.
  • Created network-watchdog.py as a lightweight daemon to handle Wi-Fi recovery (unloading/loading kernel drivers dynamically via rmmod/modprobe) and restarting hostapd.
  • Relied on systemd Restart=always overrides for process management instead of Python-based checks.

2. Deprecation of brand.txt (Completed)

Goal: Eliminate dual-source-of-truth syncing between brand.txt and brand.j2. Move all remaining system components to read directly from the JSON-based brand.j2 file. Changes Made:

  1. Updated globals.py to exclusively read and load configuration from /usr/local/connectbox/brand.j2 instead of brand.txt.
  2. Cleaned up obsolete synchronization code in globals.py, completely removing any reads or writes to /usr/local/connectbox/brand.txt.
  3. Updated BrandCreationTool.py to output configurations directly to brand.j2.
  4. Modified buttons.py, usb.py, hats.py, and mmiLoader.py to correctly reflect the updated brand.j2 references, eliminating confusing/outdated comments referencing brand.txt.
  5. Removed the sync_brand() logic entirely from network-watchdog.py.
  6. Moving forward, the source of truth for device branding and specific flag configurations like usb0NoMount will exclusively be brand.j2.
