python - Extracting tar file with original time stamp -


my objective extract archive file members different location original timestamps using python 2.6.

for example :

tar -tzvf nas_archive_11-15-12.tgz -rw-r--r-- appins/app     2337 2012-11-15 10:25:09 nfs4exports/opt/prod/fmac/files/inbound/test_archive/a.txt.gpg

i want restore above file "/nfs4exports/opt/prod/fmac/files/inbound/test_archive/11-15-12/a.txt.gpg" since last modified on 15th november 2012.

i have created following script :

#!/usr/bin/python  import os, tarfile datetime import datetime, date, timedelta import datetime  a_path = '/home/appins/.scripts/'  root, subfolders, files in os.walk(a_path):         file in files:            if file.startswith("nas_archive"):                 print file, " getting extracted"                 mytar = tarfile.open(file)                 member in mytar.getmembers():                     if member.isreg():                         myname = '/' + member.name                         path_list = myname.rsplit('/')[1:]                         print path_list                         member.name = os.path.basename(member.name)                         i_base = 'inbound'                         = -1                         index,value in enumerate(path_list):                             if value == i_base:                                 = index                                 break                         if == -1:                             print i_base, " not found"                         else:                             path_list.insert(index + 2, '11-15-12')                             path_list.remove(member.name)                         print path_list                         newpath = '/' +  os.path.join(*path_list)                         print newpath                         mytar.extract(member,newpath)

this script working expected extracting files today's timestamps rather original time stamp. here won't able use extractall method since calculating path separately each file based on original path. there way me restore file new location original timestamps?

you need @ the mtime attribute of tarinfo objects:

import tarfile tar = tarfile.open('tarfile.tar') member in tar.getmembers():     print member.name, member.mtime

given mtime value, can use os.utime set both access , modification timestamps thus:

import os os.utime('file', (mtime, mtime))

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
