Snor,
The simplest solution is to change your system and put the DB on the

to complete (avoid the TCP stack completely). This way you might not

possible to recreate the tcp streams (a lot of packet capturing devices
already do that). So the gateway would have to have some kind of a
dispatch that would recognize the initialization of a chat loggon and
start a capture pr
Michael,
You only need to call the __init__ method of the superclass if you need
to do something special during initialization. In general I just use
the SuperClass.__init__(self,...) way of calling the super class
constructors. This way, I only initialize the immediate parents and
they will in tur
John,
Cycles are tricky. Python is an interpreted dynamic language, whatever
object you instantiate in your methods is a different thing than class
hierarchy. Your class hierarchy is fine: ClassA->ClassASubclass->ClassC
and it should work. If it doesn't, create a quick mock example and
post it alo
Brian,
You can try the setdefault method of the dictionary.
For a dictionary D the setdefault work like this:
D.setdefault(k, defvalue). If k not in D then D[k] is set to defvalue
and defvalue is returned.
For example:
In [1]: d={}
In [2]: d.setdefault(1,5)
Out[2]:5
In [3]: d
Out[3]:{1: 5}
In y
Use it anywhere a quick definition of a function is needed that can be
written as an expression. For example when a callback function is
needed you could say:
def callback(x,y):
return x*y
some_function(when_done_call_this=callback)
But with lambda you could just write
some_function(when_done_cal
idea from above won't work too well, you
will have to capture all the traffic then decode each stream, for each
side, for each protocol.
3) Recording or replay is easy. Save to files or dump to a MySQL table
indexed by user id, timestamp, IP etc. Because of buffering issues you
will probably
;t be able to jump to line 15000 without
reading lines 0-14999. You can either iterate over the rows by yourself
or simply use the 'linecache' module like shown above. If I were you I
would use the linecache, but of course you don't mention anything about
the context of your project
