The stock socket should work and I think I've missed an obvious bug in the code other than checking the return status. Obviously you wanted to recv() on your 'clientsocket' not your 'seversocket'. You can use sendall() to send all the given data; it will raise an exception if it fails so there's no return code to check. Since TCP is a stream protocol and does not have any concept of message boundaries, you'll need to delimit messages within your protocol, and call recv() until you have an entire message. -- --Bryan -- http://mail.python.org/mailman/listinfo/python-list

Re: Access to static members from inside a method decorator?
[EMAIL PROTECTED] wrote: Thanks for all the help guys ... in almost every way using a metaclass seems to be the right solution for what I'm trying to do here. I say almost because there is one thing that is still confusing me: what is the most elegant way to provide base-class implementations of methods that are expected to be overriden by some of the derived classes (or in the case of metaclasses, the classes that either declare __metaclass__ = Exposed or are derived from such classes). Here's what I've just knocked out: [snip example] The problem here is that the implementation of 'bar' inside Exposed.__init__ overrides the implementation of bar() in Process, which makes sense I guess seeing as Exposed.__init__() is called after the class has been initialised. It's not a problem for getExposedMethods() seeing as it's not overriden by any derived classes. So what is the accepted way of doing this? Do I need two Exposed classes, one is the metaclass that handles all the static mapping stuff, and another provides base implementations of methods and is what is actually derived from? E.g.: You define one base type with a custom metaclass and inherit from that. Your example then becomes: import sys class ExposedType( type ): def __init__( cls, *args, **kw ): # Track marked exposed methods cls.s_exposedMethods = [] for superclass in cls.__mro__: for name, meth in superclass.__dict__.items(): if hasattr( meth, exposed ): cls.s_exposedMethods.append( name ) class Exposed: __metaclass__ = ExposedType def getExposedMethods(self): return self.s_exposedMethods def bar(self): print bar\n @staticmethod def expose( f ): f.exposed = True return f class Process( Exposed): @Exposed.expose def foo( self ): pass def bar( self ): print BAR class BotProcess( Process ): @Exposed.expose def addBots( self ): pass p = Process() p.bar() This prints BAR as expected.

If we would use a tracker that is free software, yet hosted it elsewhere, the same thing could happen: the hoster could make modifications to it which are non-free. Not even the GPL could protect from this case: the hoster would be required to publish source only if he publishes binaries, but he wouldn't publish any binaries, so he wouldn't need to release the source changes, either. Also, even if it the software is open source and unmodified, there still wouldn't be a guarantee that you can get the data out of it if you want to. You *only* get the advantages of free software if you also run it yourself. Unfortunately, there is a significant cost associated with running the software yourself. You have many good points here, Martin.

Of course, spreading the load among several people helps with the other tasks as well.

In my case, I will have a thread for input, as well as one for output to send commands away. The bit I was complaining about above is the replacement of a thread to do the animation timing with a stutter machine inside the gui thread, where the timing is handled by callbacks. A piece of feedback - the stutter machine animation timing is much smoother than the timing based on threaded sleep calls - less jittery - looks much better... So I am kind of glad the thing fell over because this implementation is going to be much better. Thank You All. - Hendrik -- http://mail.python.org/mailman/listinfo/python-list

groupby and itemgetter
Hello, there is an example how to use groupby in the itertools documentation (http://docs.python.org/lib/itertools-example.html): # Show a dictionary sorted and grouped by value from operator import itemgetter d = dict(a=1, b=2, c=1, d=2, e=1, f=2, g=3) di = sorted(d.iteritems(), key=itemgetter(1)) for k, g in groupby(di, key=itemgetter(1)): ... print k, map(itemgetter(0), g) ... 1 ['a', 'c', 'e'] 2 ['b', 'd', 'f'] 3 ['g'] Now i wonder why itemgetter is used in this example. More straightforward is: d = dict(a=1, b=2, c=1, d=2, e=1, f=2, g=3) di = sorted(d.iterkeys(), key=d.get) for k, g in groupby(di, key=d.get): ... print k, list(g) ... 1 ['a', 'c', 'e'] 2 ['b', 'd', 'f'] 3 ['g'] This code does not need the operator module, and its also faster (tested using timeit).

'some text'
I actually want to extract the lines with the numbers, write
them to a file and finally use gnuplot for plotting them. A
nicer and more python way would be to extract those numbers,
write them into an array according to their column and plot
those using the gnuplot or matplotlib module :-)
Unfortunately, I am pretty new to the re module and tried
the following so far:
import re
pat = re.compile('\ \ \ NO.*?', re.DOTALL)
print re.sub(pat, '', open('log_star_orig').read())
but this works just the other way around, which means that
the original log file is printed without the number part. So
the next step would be to delete the part from the first
line to '\ \ \ \ NO' and the part from '' to the end,
but I do not know how to address the first and last line!?
Would be nice, if you can give me a hint and especially
interesting would it be, when you have an idea, how I can
put those columns in arrays, so I can plot them right away!
A more difficult log file looks like:

Using twisted, not telnetlib for interactive telnet (WAS: RE: Improving telnetlib)
The trouble is, I havent got a clue where to start and would appreciate a couple of pointers to get me going... I'd suggest taking a look at Twisted, which contains a more complete telnet implementation (not as important for being able to launch vi), an ssh implementation (which you might want to use instead of telnet), a VT102 implementation (which is actually what will help you run programs that want to fiddle around with the cursor in fancy ways), as well as a fair amount of work towards a simple terminal emulator (to help you keep track of what vi has done to your virtual terminal). API docs for insults: http://twistedmatrix.com/documents/current/api/twisted.conch.i nsults.html And for the telnet implementation: http://twistedmatrix.com/documents/current/api/twisted.conch.t elnet.html Looking through those docs quickly leads me into quite a bewildering maze. As a kind of way to perhaps get me heading in the right direction and understanding how I start to hang all that together to get what I want, I would appreciate it if anyone could look at this little code snippet I have, and illustrate how I can end up doing the same thing with twisted, but end up with an interactive connection that can handle vi... From there I will happily trundle off by myself. I think I'm looking for help in getting that AhA! moment :) Snippet; C=telnetlib.Telnet(self.TCPAddress) . . ((connection / password handling etc..)) . . if AliasedSubbedCmd=='__interact': if system=='UNIX': retkey='^D' else: retkey='^Z' print '\nTELNET entity '+self.Name+' entering interactive mode.

Ian Bicking wrote: It handles some other kinds of repositories now (bzr, I think?). From what I understand fully abstracting out the repository format seems to still be a work in progress, but it is in progress and you can write repository plugins right now. That covers Trac, but other projects probably need to get up to speed with providing similar functionality, too. This is another case where people should work together rather than developing an interoperability layer specific to their own project. Certainly, the Bazaar APIs looked like some kind of promising umbrella project for that kind of thing. Trac now includes a WSGI backend, and someone has written a WSGI backend for ViewVC (though I don't know if it is included with the project). Clearly you need to get on the WSGI bandwagon ;) Hey, WebStack supports WSGI, too, you know. ;-) Paul -- http://mail.python.org/mailman/listinfo/python-list

I think it is a reasonable assumption that if it isn't necessary, most users will elide the keywords. What I am argueing is that it is very natural for python programmers to assume that keyword arguments will work if they see a signature. IMO if a python programmer sees something like: abs(x) It is very natural to envision a corresponding def statement like: def abs(x): and a python function written like this will work if called as follows: abs(x=5) IMO this is a very natural thought process for a python programmer. So a python programmer seeing the first will tend to expect that last call to work. Now frederic claims that the general rule is different. Now I'm perfectly happy to accept that those who write the documentation do so based aacording to the rule frederic stated (you can't/shouldn't use a parameter as a keyword argument unless explictly stated in the documentation), but that doesn't contradict that readers may have different expectations. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list

Whats wrong with second print statement? When I give the discriptor or index explicitly its giving the correct answer. Why not in the loop? Am I wrong some where? Please help me.

Re: Access to static members from inside a method decorator?
no need for all that,i wrote a basic Ajax framework for cherrypy that features a Ajax.Net feature,exposing functions to JavaScript via attributes(or in python via decorators),here is a decorator that run one time(i.e. before running the actual code) and get the name of the class [code] def AddFunction(func): stack=inspect.stack() ClsName=stack[1][3]#get the class name from the stack #now you both have the ClassName and the func object,so you can populate your list return func#return the decorated function [/code] it use the module inspect,to inspect the stack. -- http://mail.python.org/mailman/listinfo/python-list

Re: extract certain values from file with re
Hi Fabian,
I'm still a youngster in Python but I think I can help with the
extracting data from the log file part. As I'm seeing it right now,
the only character separating the numbers below is the space character.
You could try splitting all the lines by that character starting from
the NO Column. The starting point of the split function could easily be
defined by regexes. Using this regex : \s+\d+\s{1,2}[\d\w\.-]*\s+ ... I
was able to extract the 2 first columns of every row. And since the
while document is structured like a table, you could define a
particular index for each of the columns of the split result.
I sincerely hope this can help in any way :)
