Hi,
I'm writing a file system under fuse-python. The main problem I'm
facing now is that the flags which are provided by the fuse module
when r/w are called, are screwing up the situation.
I wrote a file class for fuse as shown below.
class FlusterFile(object):
def __init__(self,
Anyone got any idea of how to create a 256 byte/block filesystem using
FUSE in python ? How to implement block level reads/writes instead of
byte level reads/writes in fuse-python ?

The break and continue problem was actually my own mistake. I wrote
no_blks = length/4096 + 1, so the loop actually executes twice. Sorry
for my idiotic mistake
But the read() problem still persists.
Thanks..

By redirection I meant reading the snapshot file instead of the

Hi everyone,
I need to implement custom import hooks for an application (http://
www.python.org/dev/peps/pep-0302/). I want to restrict an application
to import certain modules (say socket module). Google app engine is
using a module hook to do this (HardenedModulesHook in google/

Hi,
I know this is not the best way to do it. But I have to do it at least
to make it *hard* to decompile the python bytecode.
I want to distribute a software written in Python without the source.
So I compiled Python from source changing some opcode values (Taking
care of HAVE_ARGUMENT value) an
