Python文件完整性監控

Question

我寫了下面的代碼，無法讓它工作，我看不出爲什麼。代碼：

1. 讀取目標文件的列表
2. 遍歷目錄
3. 奔跑MD5哈希上的文件
4. 檢查ACTIVEFILE對於以前的MD5哈希值的所述文件
5. 如果該文件是新的它會將其記錄爲新的
6. 如果日誌已存在但已更改，它將寫入更改並記錄更改
7. 如果不是新的並且沒有更改，則不要NG

下面是代碼：

import hashlib 
import logging as log 
import optparse 
import os 
import re 
import sys 
import glob 
import shutil 

def md5(fileName): 
    """Compute md5 hash of the specified file""" 
    try: 
     fileHandle = open(fileName, "rb") 
    except IOError: 
     return 
    m5Hash = hashlib.md5() 
    while True: 
     data = fileHandle.read(8192) 
     if not data: 
      break 
     m5Hash.update(data) 
    fileHandle.close() 
    return m5Hash.hexdigest() 

req = open("requested.txt") 
for reqline in req: 
    reqName = reqline[reqline.rfind('/') + 1:len(reqline) - 1] 
    reqDir = reqline[0:reqline.rfind('/') + 1] 
    tempFile = open("activetemp.txt", 'w') 
    for name in glob.glob(reqDir + reqName):  
     fileHash = md5(name) 
     actInt = 0 
     if fileHash != None: 

      actFile = open("activefile.txt") 

      for actLine in actFile: 
       actNameDir = actLine[0:actLine.rfind(' : ')] 
       actHash = actLine[actLine.rfind(' : ') + 3:len(actLine) -1] 
       if actNameDir == name and actHash == fileHash: 
        tempFile.write(name + " : " + fileHash + "\n") 
        actInt = 1 
        print fileHash 
        print actHash 
        print name 
        print actNameDir 
       if actNameDir == name and actHash != fileHash: 
        fimlog = open("fimlog.txt", 'a') 
        tempFile.write(name + " : " + actHash + "\n")   
        actInt = 1 
        fimlog.write("FIM Log: The file " + name + " was modified: " + actHash + "\n") 
      if actInt == 0: 
       fimlog = open("fimlog.txt", 'a') 
       fimlog.write("FIM Log: The file " + name + " was created: " + fileHash + "\n") 
       tempFile.write(name + " : " + fileHash + "\n")      

shutil.copyfile("activetemp.txt", "activefile.txt")

你從來沒有真正描述的問題，但一個可能的罪魁禍首是你從來沒有關閉臨時文件（或其他文件，爲這一問題），因此該文件最後複製可能會失敗。
