POPython recursion limit

copied!<p>So I understand the reason for the recursion limit of 1000. I want to run a script continuously, but am I right understanding that eventually the recursion limit will be reached (even if I set it higher) and Python will break?</p> <p>In the scheme of things, its not a big deal, because I could get the OS to keep re-starting the script, but I thought there may be a more elegant solution I can employ within the script itself (swapping threads??).</p> <p>My script:</p> <pre><code>import os import subprocess import time import logging import datetime from sys import argv if len(argv) < 3: exit('Please provide two arguments - Source Destination') LOC_DIR = argv[1] REM_DIR = argv[2] POLL_INT = 10 RUN_INT = 60 FILE_EXT = '.mov' # logging setup logging.basicConfig(filename='%s' % os.path.join(LOC_DIR, '%s the_log.log' % datetime.datetime.now()),level=logging.DEBUG) # make an easy print and logging function def printLog(string): print '%s %s' % (datetime.datetime.now(), string) logging.info('%s %s' % (datetime.datetime.now(), string)) # get the files with absolute paths def getFiles(path): return [os.path.join(path, entry) for entry in os.listdir(path)] # check if file is still being copied (file size has changed within the poll interval) def checkSize(path): same = False while same is False: printLog("Processing '%s'" % os.path.basename(path)) printLog('Waiting %s seconds for any filesize change' % POLL_INT) size1 = os.path.getsize(path) time.sleep(POLL_INT) size2 = os.path.getsize(path) if size1 == size2: same = True printLog('File size stayed the same for %s seconds' % POLL_INT) return same else: printLog('File size change detected.
