Temp File Cleanup for McMillan Installer Pgms

[achrist@easystreet.com]

After using the McMillan installer and executables built with
it for a while, I've noticed some residual files accumulating
on my disk. The installer docs mentions these.

Here's code I wrote to clean these up:

--------------------Program Fillows----------------------

import fnmatch
import os
import os.path
import stat
import tempfile
import time

currentTime = time.time()

def PathIsOld(pathN ame):
accessTime = os.stat(pathNam e)[stat.ST_ATIME]
createTime = os.stat(pathNam e)[stat.ST_CTIME]
modifiedTime = os.stat(pathNam e)[stat.ST_MTIME]
return (((currentTime - accessTime) > 5000) or (
(currentTime - createTime) > 50000)) and (
(currentTime - modifiedTime) > 5000)


def GetMEISubdirect ories(aDir):
for fName in os.listdir(aDir ):
if fnmatch.fnmatch (fName, "*"):
if fName.lower()[:4] == '_mei':
fullName = os.path.join(aD ir, fName)
fMode = os.stat(fullNam e)[stat.ST_MODE]
if stat.S_ISDIR(fM ode):
yield fullName

def GetMEIFiles(aDi r):
for fName in os.listdir(aDir ):
if fName.lower()[:4] == '_mei':
fullName = os.path.join(aD ir, fName)
fMode = os.stat(fullNam e)[stat.ST_MODE]
if stat.S_ISREG(fM ode):
yield fullName


def GetTempLocation ():
return tempfile.gettem pdir()

def GetMEIDirectori es():
return filter(
PathIsOld,
GetMEISubdirect ories(GetTempLo cation())
)

def DeleteMEIDirect ory(d):
for fileName in os.listdir(d):
fullName = os.path.join(d, fileName)
try:
os.remove(fullN ame)
except:
pass
try:
os.rmdir(d)
except:
pass

for d in GetMEIDirectori es():
DeleteMEIDirect ory(d)

for f in GetMEIFiles(Get TempLocation()) :
if PathIsOld(f):
os.remove(f)

-----------------------End of Program -------------------------

What are the top 10 reasons for not including this in every
program that I turn into an executable with the McMillan
installer?

TIA
