adds support for forks that maintain custom changes and need to merge from upstream instead of resetting. the new GIT_MODE=merge option in update.sh calls git_merge_from_upstream() which fetches and merges upstream/main while preserving local commits.

# update.sh - Main update orchestrator
|
|
# =============================================================================
|
|
# Performs a full system and service update:
|
|
# 1. Backs up user-customizable directories (e.g., python-runner/)
|
|
# 2. Syncs with remote repository (method depends on GIT_MODE)
|
|
# 3. Restores backed up directories to preserve user modifications
|
|
# 4. Updates Ubuntu system packages (apt-get update && upgrade)
|
|
# 5. Delegates to apply_update.sh for service updates
|
|
#
|
|
# This two-stage approach ensures apply_update.sh itself gets updated before
|
|
# running, so new update logic is always applied.
|
|
#
|
|
# Git modes (set via GIT_MODE environment variable):
|
|
# - reset (default): git fetch + reset --hard origin/<branch>
|
|
# Best for: Standard installations, always syncs cleanly with remote
|
|
# - merge: git fetch upstream + merge upstream/<branch>
|
|
# Best for: Forks that maintain their own changes and merge from upstream
|
|
#
|
|
# Preserved directories: Defined in PRESERVE_DIRS array in utils.sh.
|
|
# These directories contain user-customizable content that survives git reset.
|
|
#
|
|
# Usage:
|
|
# make update - Standard update (reset mode)
|
|
# make git-pull - Fork update (merge mode)
|
|
# GIT_MODE=merge sudo bash scripts/update.sh - Manual merge mode
