Re: Storing a callback function as a class member

[Nathan Huesken]

Hey,

Sorry, I tried to sent only the relevant parts of the example, but the
part where the error was, was left out.

I defined the function, used as callback like this:
class SomeClass:
def callback(param):
...

So I forgot the self parameter, and therefor the callback had a
different number of parameters than I expected.

Thanks for the effort!

I am packing large files with tarfile. Is there any way I can get
progress information while packing?

Thanks!

Storing a callback function as a class member

[Nathan Huesken]

Hi,

I have a class, where I want to store a callback function as a member
to access later:

class CallbackClass:
def setCallback(self,cb):
self.cb = cb

def callCallback(self, para):
self.cb(para)

Doing so, I get the error:
callbackFunc() takes exactly 1 parameter (2 given)

self is given as parameter this way, is it not? How can this be done?

Thanks!

importing modules from higher level directory

[Nathan Huesken]

Hi,

Is it somehow possible to import modules from *.py files in a higher
level directory?
Intuitively I would do

import ../module

but that does not work.
How does it work?

Thanks!

File descriptor to file object

[Nathan Huesken]

Hi,

tempfile.mkstemp returns a file name and a file descriptor (as returned
by os.open). Can I somehow convert this descriptor to a file object?

Thanks!

Re: FIle transfer over network - with Pyro?

[Nathan Huesken]

Thanks for all the replies.
I might use http, or I utilize a separate ftp server.

  Didn't the OP request something fast?
 
 Nope. He pointed out that pyro is not efficient and asked what
 libraries we would use.
 
 OP: HTTP is a reasonable choice unless you need really extreme
 performance.

FIle transfer over network - with Pyro?

[Nathan Huesken]

Hi,

I am writing a network application which needs from time to time do
file transfer (I am writing the server as well as the client).
For simple network messages, I use pyro because it is very comfortable.
But I suspect, that doing a file transfer is very inefficient over
pyro, am I right (the files are pretty big)?

I somehow need to ensure, that the client requesting a file transfer is
the same client getting the file. So some sort of authentication is
needed.

What library would you use to do the file transfer?
Regards,
Nathan
