TarFile using binary strings

[Marc Poinot (Onera)]

Hi all,

I have a DBMS with Blobs, I want to export them into a tar.gz file using
the TarFile module.
So far, I'm using a temporary file for the tar file creation, each blob
is exported into a
file and then added to the tar file.

Is it possible to avoid the temporary files, and read the stream from
the binary string coming
from DBMS ? The TarInfo object uses a fileobj Python type, is there any
trick (or module) to
make TarInfo happy with a 'possible' fileobj-like on a memory zone ?
