os.walk/list
so i am trying to add md5 checksum calc to my file copy stuff, to make sure the source and dest. are same file. i implemented it fine with the single file copy part. something like : for files in sourcepath: f1=file(files ,'rb') try: shutil.copy2(files, os.path.join(destpath,os.path.basename(files))) except: print "error file" f2=file(os.path.join(destpath,os.path.basename(files)), 'rb') truth = md5.new(f1.read()).digest() == md5.new(f2.read()).digest() if truth == 0: print "file copy error" this worked swimmingly. i moved on to my backupall function, something like for (path, dirs, files) in os.walk(source): #os.walk drills down thru all the folders of source for fname in dirs: currentdir = destination+leftover try: os.mkdir(os.path.join(currentdir,fname),0755) except: print "error folder" for fname in files: leftover = path.replace(source, '') currentdir = destination+leftover f1=file(files ,'rb') try: shutil.copy2(os.path.join(path,fname), os.path.join(currentdir,fname)) f2 = file(os.path.join(currentdir,fname,files)) except: print "error file" truth = md5.new(f1.read()).digest() == md5.new(f2.read()).digest() if truth == 0: print "file copy error" but here, "fname" is a list, not a single file.i didn't really want to spend a lot of time on the md5 part. thought it would be an easy add- on. i don't really want to write the file names out to a list and parse through them one a time doing the calc, but it sounds like i will have to do something like that. -- http://mail.python.org/mailman/listinfo/python-list
Re: os.walk/list
yes i agree breaking stuff into smaller chunks is a good way to do it. even were i to do something like def safe_copy() f1=file(files ,'rb') f2 = file(os.path.join(currentdir,fname,files)) truth = md5.new(f1.read()).digest() == md5.new(f2.read()).digest() if truth == 0: print "file copy error" that would probably work for the single file copy functions. but would still breakdown during the for ...os.walk(), again because "fname" is a list there, and the crypto functions work 1 file at a time. even changing crypto functions wouldn't change that. -- http://mail.python.org/mailman/listinfo/python-list
python time
I'm working on a script that will run all the time. at time specified
in a config file, will kick-off a backup.
problem is, its not actually starting the job. the double while loop
runs, the first comparing date works. the second for hour/min does
not.
#python file
import os,string,,time,getpass,ConfigParser
from datetime import *
from os.path import join, getsize
from time import strftime,localtime
config = ConfigParser.ConfigParser()
config.read("config.ini")
source = config.get("myvars", "source")
destination = config.get("myvars", "destination")
date = config.get("myvars", "date")
time = config.get("myvars", "time")
str_time=strftime("%H:%M",localtime())
while datetime.now().weekday() == int(date):
while str_time == time:
print "do it"
#config file
#change the time variable to "now"+a min or two to observe
#this needs to be where ever the actual python script is
[myvars]
#only set source if you want it to be different
source: c:\users\jon

#what day of the week to perform backup?where Monday is 0 and Sunday

i guess im just having a hard time creating something like
check if go condition,
else sleep
the double while loops take 12% cpu usage on my machine so this is
probably unacceptable.
also the sleep command does not like me :
>>> from datetime import *
>>> from time import strftime,localtime,sleep
>>> time.sleep(3)
Traceback (most recent call last):
File "", line 1, in
time.sleep(3)
AttributeError: type object 'datetime.time' has no attribute 'sleep'
>>>
here it is updated with the hour/min check fixed.
#updated python code
import os,string,time,getpass,md5,ConfigParser
from datetime import *
from os.path import join, getsize
from time import strftime,localtime,sleep
config = ConfigParser.ConfigParser()

i think this is what you are talking about
except that the time.sleep just does not work.
even changing "from time import strftime,localtime" to "from time
import strftime,localtime,sleep" does not do it.
#python code

Re: python time
i see. i was using time as a variable name , messing it all up.im not
going to post the whole backup script here, but here are a few lines
that i changed to make it work.
from datetime import datetime
from os.path import join, getsize
import time,os,string,getpass,md5,ConfigParser
from time import strftime,localtime
hrmin = config.get("myvars", "hrmin") #was time =, this is what did
it.
while a>0:
if datetime.now().weekday() == int(date):
str_time=strftime("%H:%M",localtime())
if str_time == hrmin:
print "do it"
os.system(cmd)
time.sleep(5)#will prolly want to change to to 30 or higher for

string to path problem
i am writing a basic backup program for my school. so they wanted the
possibility to be able to set source/destination from a config file.
my source/destination was fine before, i would build it up with
functions, like 1 that got the user-name, and put it all together with
os.path.join. but if they set a source in the config file to something
like c:\users\jon\backup python tries to read from c:\\users\\jon\
\backup, and throws out a read permission (because it doesn't
exist ...). i am not sure what to do at this point. i have look at the
docs for string, and os. . i cant os.path.join anything if they
give me an absolute path. here is a bit of the code
import os,string,fnmatch,shutil,time,getpass,md5,ConfigParser
from datetime import *
from os.path import join, getsize
config = ConfigParser.ConfigParser()
config.read("config.ini")
source = config.get("myvars", "source")
destination = config.get("myvars", "destination")
helptext = config.get("myvars", "helptext")
def weekChoice():
dateNum = datetime.now().day
if dateNum <=7:
week = 1
elif (dateNum >= 8) and (dateNum <= 14):
week = 2
elif (dateNum >= 15) and (dateNum <= 21):
week = 3
elif dateNum > 22:
week = 4
else:
print "error"
return week
def destination1():
global destination
username = getpass.getuser()
week = weekChoice()
weekstr = "week"+str(week)
destination1 = os.path.join("//mothera","jon","week1") #where //
mothera is a samba server on the network
return destination1
print "source :",source
destination = destination1()
shutil.copy2(source, destination)
here is some of config.ini
[myvars]
source:c:\users\jon\backup

homedir, file copy
hello,
i am trying to work with windows homedirectory as a starting point for
some kind of file copy command. i'm testing this on a win7 box so my
home is c:\Users\jon\
here is the code snippet i am working on:
import os
homedir = os.path.expanduser('~')
try:
from win32com.shell import shellcon, shell
homedir = shell.SHGetFolderPath(0, shellcon.CSIDL_APPDATA, 0, 0)
except ImportError:
homedir = os.path.expanduser("~")
print homedir
print os.listdir(homedir+"\\backup\\")
homedir.replace("" , "\\")
print homedir
shutil.copy (homedir+"\\backup\\", homedir+"\\backup2\\")
output looks like:
C:\Users\jon
['test1.txt', 'test2.txt']
C:\Users\jon
Traceback (most recent call last):
File "D:\spring 11\capstone-project\date.py", line 43, in

with open(src, 'rb') as fsrc:
IOError: [Errno 2] No such file or directory: 'C:\\Users\\jon\\backup\

i will, closer towards the end.
just wanted to get past the naming stuff, the problem above.
right now i just want to see it move files from 1 place to another.
i had copytree in before, and will go back to that for final version.
im working on a backup program, and copytree looks yummy.
still no idea why getting permission denied.

files,folders,paths
i have a samba server at home (acting as my test environment) with one of the 'shares' mounted as v: on my windows box. inside of that are 4 folders week[1-4]. i have created c:\users\name\backup , and put a few files/folders in there to test with. please ignore the wxpython parts of the script, the last 1/3, that part is functional. initial test was looking good. (in the code, ver011 source1, destination1) coping files/ folders and not clobbering files. going to version 12a, it seems like it is trying to copy the files under the folder, before making the folder. or doing the copy2 part before the copytree part. i dont know why it works on ver011, and not in ver12a, the only difference being the destination. http://thanksforallthefish.endofinternet.net/ facbac-011.py">facbac 011 http://thanksforallthefish.endofinternet.net/ facbac-012a.py">facbac 012a Traceback (most recent call last): File "I:\college\spring11\capstone-project\facbac-012a.py", line 161, in button1Click backupall() File "I:\college\spring11\capstone-project\facbac-012a.py", line 81, in backupall shutil.copy2(filesource, filedest1) File "C:\Python27\lib\shutil.py", line 127, in copy2 copyfile(src, dst) File "C:\Python27\lib\shutil.py", line 82, in copyfile with open(dst, 'wb') as fdst: IOError: [Errno 2] No such file or directory: 'V:\\week2\\configs\ \apache2.conf' here, apache2.conf = c:\users\name\backup\config\apache2.conf trying to copy to v:\week2\config\apache2.conf but there is no v:\week2\config as it has not made the config folder yet i think the problem might be the \\ in the destination name. -- http://mail.python.org/mailman/listinfo/python-list

if i do not change the directory how do i get the relative folder
path. for example,
starting with c:\users\name\backup\folder1\folder2\file
as the oswalk drills down through the folders, when it is in the
'folder2' folder, if you do something like
print dirs
it would output just 'folder2' not the whole path or any of the other
parts.
so how do i know where to write this to on the destination relative
to
\\servername\username\week[1-4]\ or possibly that folder mounted as a
drive in windows as
v:\week[1-4]\ ?
how do i build the output folder name.
bear in mind it works great in version 011.
i spent weeks, and tried maybe 7 different other ways before going
down this path, so to speak.
i thought about using a list. or an array. but you wouldnt know when
oswalk starts bak from top level to go int another folder. let me
think if i can say it another way. ...
i think what you guys want me to do the osjoin on is this line
destination = r"Mothera\\"+username+"\\"+weekstr or
shutil.copytree(os.getcwd(), destination+leftover)
please clarify.

i think i got it. my dirlist wasn't the right way to go, i needed to iterate thu what oswalk was giving me in dirs, and files. not bruteforce strip to a string. i have been starting at an early version and a later version for the last 4 hours or so, and i think i have it this only handles the folders. i wanted to try out the logic before i doubled up and parsed files too. substitute this in for the backup function. and for now the source and destination functions are in this to. ill clean it up once i test it more. backupdir = os.path.join(homedir, "backup") remotedir = os.path.join(homedir, "backup2") weekstr = "week"+str(week) remotedirweek = os.path.join(remotedir, weekstr) print '' for (path, dirs, files) in os.walk(backupdir): print "current path is : ",path print "current dir is : ",dirs print "current files are: ",files for fname in dirs: os.chdir(path) leftover = os.getcwd().replace(backupdir, '') print "leftover is:",leftover print "remotedirweek is:",remotedirweek currentdir1 = remotedirweek+leftover if not os.path.isdir(currentdir1): print "currentdir1:",currentdir1 print "i should copy teh folderz",os.path.join(currentdir1,fname) shutil.copytree(os.getcwd(),os.path.join(currentdir1,fname)) -- http://mail.python.org/mailman/listinfo/python-list

Re: files,folders,paths
well i think i will close this out. redid recursive foldering now for
3rd or 4th time. below script works from a windows to another folder
(destination1) or a unc path(destination2). i tried it on my linux
box, and the error deals with writing to a remote smb share. i think
if it was mounted somewhere, it would work fine with something like
dest1, but changing the path(or mounting the remote drive to backup2
for the lazy ).

file/folder naming
im trying to use wxpython to get a source file/files, then a
destination folder to write them to. the file and folder picker works.
the problem is, actually copying (actually shutil.copy2() ). i get an
except error, as if the destination file name is not correct. looking
at the print lines the destination looks right. i used os.path.join to
join the folder path and the filebasename. i can hear it now, that
this belongs on the wxpython page, and i will be posting there as
well. but, im fairly certain its something in this "for files in
sourcepath:"
