# API.FUNC - TELEMETRY & DIAGNOSTICS API
# ==============================================================================
#
# Provides functions for sending anonymous telemetry data to Community-Scripts
# API for analytics and diagnostics purposes.
#
# Features:
# - Container/VM creation statistics
# - Installation success/failure tracking
# - Error code mapping and reporting
# - Privacy-respecting anonymous telemetry
#
# Usage:
# source <(curl -fsSL .../api.func)
# post_to_api # Report container creation
# post_update_to_api # Report installation status
#
# Privacy:
# - Only anonymous statistics (no personal data)
# - User can opt-out via diagnostics settings
# - Random UUID for session tracking only
#
# ==============================================================================
# ==============================================================================
# SECTION 1: ERROR CODE DESCRIPTIONS
# ==============================================================================
# ------------------------------------------------------------------------------
# explain_exit_code()
#
# - Maps numeric exit codes to human-readable error descriptions
# - Supports:
# * Generic/Shell errors (1, 2, 126, 127, 128, 130, 137, 139, 143)
# * Package manager errors (APT, DPKG: 100, 101, 255)
# * Node.js/npm errors (243-249, 254)
# * Python/pip/uv errors (210-212)
# * PostgreSQL errors (231-234)
# * MySQL/MariaDB errors (241-244)
# * MongoDB errors (251-254)
# * Proxmox custom codes (200-231)
# - Returns description string for given exit code
# - Shared function with error_handler.func for consistency

# post_to_api()

# - Sends LXC container creation statistics to Community-Scripts API
# - Only executes if:
# * curl is available

# * RANDOM_UUID is set
# - Payload includes:
# * Container type, disk size, CPU cores, RAM
# * OS type and version
# * IPv6 disable status
# * Application name (NSAPP)
# * Installation method
# * PVE version
# * Status: "installing"
# * Random UUID for session tracking
# - Anonymous telemetry (no personal data)
