# Requires Node.js 24.0.0 or higher

# Enable Node.js 24 experimental features

# === MEMORY CONFIGURATION ===
# Detect if running on a low-memory system (Pi, embedded, <4GB RAM)
# Uncomment the appropriate line for your system:

# For Raspberry Pi 4 (8GB) - recommended settings:
NODE_OPTIONS="$NODE_OPTIONS --max-old-space-size=2048"

# For Raspberry Pi 4 (4GB):
# NODE_OPTIONS="$NODE_OPTIONS --max-old-space-size=1024"

# For Raspberry Pi 3/Zero or systems with <2GB:
# NODE_OPTIONS="$NODE_OPTIONS --max-old-space-size=512"

# For large servers (16GB+ RAM):
# NODE_OPTIONS="$NODE_OPTIONS --max-old-space-size=4096"

# === GARBAGE COLLECTION ===
# More aggressive GC for low-memory systems (reduces memory spikes)
# Uncomment for Pi/embedded systems:
GC_OPTIONS="--gc-interval=100"

# === ARM/FreeBSD FIX ===
# Disable Turbofan JIT optimizer - it generates illegal instructions on ARM FreeBSD
# This prevents SIGILL crashes (signal 4)
ARCH=$(uname -m)

# === NOTES ===
# If running on Pi with presence logging enabled, also set in config.json:
#   "activityLogger.lowMemoryMode": true
# This enables buffer limits and automatic cleanup of stale data.
