Hi,
I would like to read directly from a tar file into memory so I can
manipulate a file (quickly) and write its changes out to another file. I
thought I could do something like:
#!/usr/bin/env python
import tarfile
import mmap
fil = tarfile.open( "out.tar.gz" , "r:gz" )
tarinf = fil.next()
myfils = {}
while tarinf != None:
tarinf = fil.next()
ref = fil.extractfile( tarinf )
myfils[ tarinf.name ] = mmap.mmap( ref.fileno() , 0 )
But the extractfile() function of TarInfo doesn't seem to give me a fileno,
so I can't pass this to mmap.
Thoughts on a way to accomplish this?
Chris
