Code Editor : hibagent
#!/usr/bin/python3 # The EC2 Spot hibernation agent. This agent does several things: # 1. Upon startup it checks for sufficient swap space to allow hibernate and fails # if it's present but there's not enough of it. # 2. If there's no swap space, it creates it and launches a background thread to # touch all of its blocks to make sure that EBS volumes are pre-warmed. # 3. It updates the offset of the swap file in the kernel using SNAPSHOT_SET_SWAP_AREA ioctl. # 4. It daemonizes and starts a polling thread to listen for instance termination notifications. # # This file is compatible both with Python 2 and Python 3 import argparse import array import atexit import ctypes as ctypes import fcntl import mmap import os import struct import sys import syslog import requests from subprocess import check_call, check_output from threading import Thread from math import ceil from time import sleep try: from urllib.request import urlopen, Request except ImportError: from urllib2 import urlopen, Request, HTTPError try: from ConfigParser import ConfigParser, NoSectionError, NoOptionError except: from configparser import ConfigParser, NoSectionError, NoOptionError GRUB_FILE = '/boot/grub/menu.lst' GRUB2_DIR = '/etc/default/grub.d' SWAP_RESERVED_SIZE = 16384 log_to_syslog = True log_to_stderr = True IMDS_BASEURL = 'http://169.254.169.254' IMDS_API_TOKEN_PATH = 'latest/api/token' IMDS_SPOT_ACTION_PATH = 'latest/meta-data/hibernation/configured' def log(message): if log_to_syslog: syslog.syslog(message) if log_to_stderr: sys.stderr.write("%s\n" % message) def fallocate(fl, size): try: _libc = ctypes.CDLL('libc.so.6') _fallocate = _libc.fallocate _fallocate.argtypes = [ctypes.c_int, ctypes.c_int, ctypes.c_ulong, ctypes.c_ulong] # (FD, mode, offset, len) res = _fallocate(fl.fileno(), 0, 0, size) if res != 0: raise Exception("Failed to perform fallocate().
