stringio+tarfile

[superpollo]

thanks to the guys who bothered to answer me even using their chrystal 
ball ;-)

i'll try to be more specific.

yes: i want to create a tar file in memory, and add some content from a
memory buffer...

my platform:

$ uname -a
Linux fisso 2.4.24 #1 Thu Feb 12 19:49:02 CET 2004 i686 GNU/Linux
$ python -V
Python 2.3.4

following some suggestions i modified the code:

$ cat tar001.py
import tarfile
import StringIO
sfo1 = StringIO.StringIO("one\n")
sfo2 = StringIO.StringIO("two\n")
tfo = StringIO.StringIO()
tar = tarfile.open(fileobj=tfo , mode="w")
ti = tar.gettarinfo(fileobj=tfo)
for sfo in [sfo1 , sfo2]:
     tar.addfile(fileobj=sfo , tarinfo=ti)
print tfo

and that's what i get:

$ python tar001.py > tar001.out
Traceback (most recent call last):
   File "tar001.py", line 7, in ?
     ti = tar.gettarinfo(fileobj=tfo)
   File "/usr/lib/python2.3/tarfile.py", line 1060, in gettarinfo
     name = fileobj.name
AttributeError: StringIO instance has no attribute 'name'

can you help?

TIA

ps: i'd also like that the tar file has names for the buffers, so than 
once output the file can be untarred with /bin/tar into regular files...
