# pyMC Console Management Script
# Install, Upgrade, Configure, and Manage pymc_console stack
#
# INSTALLATION FLOW (mirrors upstream pyMC_Repeater):
# 1. User clones pymc_console to their preferred location (e.g., ~/pymc_console)
# 2. User runs: sudo ./manage.sh install
# 3. This script clones pyMC_Repeater as a sibling directory (e.g., ~/pyMC_Repeater)
# 4. Applies patches to the clone, then copies files to /opt/pymc_repeater
# 5. Installs Python packages from the clone directory
# 6. Overlays our React dashboard to the installation
#
# This matches upstream's flow where manage.sh runs from within a cloned repo
# and copies files to /opt. This makes it easier to:
# - Submit patches as PRs to upstream
# - Stay compatible with upstream updates
# - Allow users to switch between console and vanilla pyMC_Repeater

# ============================================================================
# Bootstrap Self-Healing (runs BEFORE anything else)
# ============================================================================
# Fixes chicken-and-egg: if git history diverged (e.g., after force-push),
# the old manage.sh can't pull the new manage.sh. This check runs early
# and resyncs if needed, then re-execs to run the updated script.

# UPSTREAM INSTALLATION MANAGER

# This section handles running pyMC_Repeater's native manage.sh installer.
# We run upstream's installer directly (user sees their native TUI), then
# apply our patches and overlay our dashboard afterward.
#
# The approach:
# 1. Clone/update pyMC_Repeater to a sibling directory
# 2. Run upstream's manage.sh (install/upgrade) in foreground - user sees TUI
# 3. Apply our patches to the installed files (/opt/pymc_repeater)
# 4. Overlay our React dashboard
# 5. Run our radio configuration
#
# Note: Upstream's radio config script is temporarily renamed during install
# so we can run our own configuration flow instead.
# ============================================================================

# Run upstream's manage.sh with a specific action
# Usage: run_upstream_installer <action> [branch]

# PATCH REGISTRY
# ============================================================================
# Core patches that enhance pyMC_Repeater with pyMC Console features.
# These patches are candidates for upstream PR submission.
#
# REMOVED (Merged Upstream in PR #36 - feat/identity branch):
# - patch_api_endpoints - /api/update_radio_config endpoint
# - patch_stats_api - Extended /api/stats with max_flood_hops, advert_interval_minutes, rx_delay_base
#
# Remaining Patches:
#
# 2. patch_logging_section (main.py)
#    - Ensures config['logging'] exists before setting level from --log-level arg
#    - Fixes KeyError when service starts with --log-level DEBUG
#    - PR Status: Pending
#
# 3. patch_log_level_api (api_endpoints.py)
#    - Adds POST /api/set_log_level endpoint
#    - Allows web UI to toggle log level (INFO/DEBUG) and restart service
#    - PR Status: Pending
#
# 4. patch_mesh_cli (mesh_cli.py)
#    - Enhances mesh CLI with MeshCore CommonCLI.cpp parity
#    - tempradio with auto-revert timer, reboot, stats-*, board, neighbor.remove
#    - Implemented via external Python patch script (patches/mesh_cli_enhancements.py)
#    - PR Status: Pending
#
# 6. patch_private_key_api (mesh_cli.py)
#    - Adds get/set prv.key for private key management via Terminal
#    - Stores key in config['mesh']['identity_key']
#    - PR Status: Pending
#
# NOTE: patch_static_file_serving was removed
# Upstream's default() method already returns index.html for all unknown routes,
# which is exactly what a true SPA needs. React Router handles client-side routing.
#
# NOTE: GPIO patches (Fix A-D) were removed after discovery that the real issue
# was a race condition in pymc_core's interrupt initialization. Adding --log-level
# DEBUG to the service provides enough delay for the asyncio event loop to
# initialize before interrupt callbacks are registered. See create_backend_service().
#
# To generate clean patches for upstream PR:
#   1. Clone fresh pyMC_Repeater
#   2. Apply patches via manage.sh upgrade
#   3. git diff > patches/feature-name.patch
