class in c subclasses python classes, called in python
I'm looking to create an application that uses c++ and python together. Currently my application is all python. But need to obfuscate some of the code. I am wanting to have c++ code so I can handle encryption with it and other tasks. But first I need it to subclass some python class objects. One task that I need to do is create a class in c++ that subclasses 3 python classes and calls the base class constructor as super would call in python. I need this in c++. How can I do this please? class ABC(a,b,c): def __init__(self, *args, **kwargs): super(ABC, self).__init__(*args, **kwargs) What I would like to know is how would I create a class in C or C++ that would: 1. create a class that subclasses 2 or more python classes 2. initializes the subclassed classes by calling the contructors like python's super would 3. import the class in python and call this class constructor with ABC(*args, **kwargs) is there a way to do this? Thanks in advance :) Thank you, -Alex Goretoy -- http://mail.python.org/mailman/listinfo/python-list
ssh browser? where?
why not ssh browser traffic? why use SSL certificate authorities which can't be trusted in the first place? Is SSH not proven to be secure?

Re: ssh browser? where?
If we were to use SSH on the web, which is certainly not the point of SSH, we'd still need some kind of certificate authority to make the whole system workable. Yeah, you are correct. I thought about that after having posted these questions. Even though it was SSH there still would be wiggle room for a mitm. I had a dream last night that my future employer was asking me what SSH was. lol I appreciate your response and making it clear as day. Still though, I think there maybe something for testing here. I personally verify and scope out my cert manually. Well for the sites I visit often. But I understand not everyone will be likely to do this.

Re: Encryption source code with md5
There's not many options when it comes to obfuscating python source. If you even do find a way to obfuscate it. It won't take much to reverse it. That's just how python works. Really I wouldn't even worry about looking for a way to do this, reason behind that is that it's not difficult to reverse it. This is not c,c++, php or java man/woman. Good luck.

Re: execute bash builtins in python
Steve thank you. The problem is that you can only run commands from Popen or
os.system and stuff. You cant run bash shell builtin commands for some
reason.
I was able to get this to work. What I did is call this:
Popen([bash -c 'source
$HOME/.bashrc;alias'],shell=True,stdout=PIPE).stdout.read()
and make sure you don't have a line like this in your .bashrc:
[ -z $PS1 ] return
Another approach I came up with was to set aliases and functions as a
environment variable and access them with os.environ.
this is how I'm doing it.
export ALIASES=`alias|awk '{print $2}'|cut -d = -f 1|xargs`
export FUNCTIONS=`declare -F|awk '{print $3}'|xargs`
use this at the end or the .bashrc and then you can access defined aliases
and functions inside python with environ

In general you'll IMHO be better off with the variables as attributes of an

If you want them to be modifiable then you can do
class Whatever: pass
myPrefix = Whatever()
myPrefix.a = 'a'
myPrefix.b = 'b'
myPrefix.c = 'c'
If you want them to be sort of constants (weasel words intentional) then
you might do (Python 3.x) -- disclaimer: off-the-cuff I'm not sure if
that function is called 'namedtuple' but I think you'll find it anyway --

a solution. I just don't know how to use setattr without it being in a
class.

Mmm, I don't quite understand what you said. lambda creates functions
that
aren't different than functions created by def: apart from the name,
they're really the same thing.
Oh, good, I'm not the only one for whom the above didn't make sense :)
I feel a little less dense now.
And if you imply that *where* you call a function does matter, it does
not. A function carries its own local namespace, its own closure, and its
global namespace. At call time, no additional binding is done (except
parameters - arguments).
(and the address space is always the one of the running process)
I poked around in the API docs and experimented with func_closure and
related attributes, and after bending my brain for a while I think I
understand this. The actual implementation of the closure is a single
list of 'cell' objects which represent namespace slots in the nested
scopes in which the closed-over function is defined.
But the fact that it is a single list is an implementation detail, and
the implementation is in fact carefully designed so that conceptually
we can think of the closure as giving the function access to those
nested-scope namespaces in almost(*) the same sense that it has a
reference to the global and local namespaces. That is, if what a name
in _any_ of those namespaces points to is changed, then the closed-over
function sees those changes.
In this way, we understand the original example: when defining a
lambda having a 'free variable' (that is, one not defined in either the
local or global scope) that was a name in the surrounding function's
local namespace, the lambda is going to see any changes made by the
surrounding function with regards to what that name points to. Thus,
the final value that the lambda uses is whatever the final value of the
for loop variable was when the surrounding function finished executing.
However, I think that a Python closure is not quite the same thing as a
'computer science' closure, for the same reason that people coming from a
language with variables-and-values as opposed to namespaces get confused
when dealing with Python function call semantics. Consider:
http://en.wikipedia.org/wiki/Closure_(computer_science)http://en.wikipedia.org/wiki/Closure_%28computer_science%29
That says that a closure can be used to provide a function with a private
set of variables that persist from one invocation to the next, so that
a value established in one call can be accessed in the next. The last
part of that sentence is not true in Python, since any assignment inside
a function affects only the local (per-invocation) namespace or (given
a global statement) the global namespace. A function cannot change the
thing pointed to by a name in the closure. Only the outer function,
for whom that name is in its local namespace, can do that.
(*) That last sentence in the previous paragraph is why I said '_almost_
the same sense' earlier: a function can modify what names point to in
its local and global namespaces, but cannot modify what names point to
in the closure namespace.
Of course, we can produce the same _effect_ as a computer science closure
in Python by using mutable objects...which is exactly parallel to the
difference between passing mutable or immutable objects in a function
call.

Re: Is python worth learning as a second language?
I've only read he subject and a few lines from other responses. yes, it is worth learning. I came from PHP to Python. It's very powerful and makes application development easier for me than in PHP and/or C#, but bash, well that depends on the type of bash. It has a lot of diffent ways you can use it too, so that adds to how powerful it is. IMHO, Bash is great for quick and dirty hacks, as a kind of simplified Perl. But when bash script grows too big, I would consider rewriting it in Python rather than Perl. But this is just my personal choice. Since we are already a little offtopic :-), did you see any speed difference between PHP and Python? I understand, that you are doing web devel in those two? yes, I am doing web developemnt. At the moment I'm playing around with GAE(google app engine), but later on I most likely will setup a django site for my combined projects set, web frontend You are right, bash is very good for simple quick and dirty hacks, but when the script growns it's much better to just use python I really can't say too much about speed increase or decrease, it really depends on the site and how its built, what libs are used and how they are loaded, same thing in PHP, It would be difficult for me to same anything on speed because of that. I built a templated modulated cms in CodeIgniter(PHP MVC), google it, It is a base for a templated system. using smarty and ci templating syntax, although the smarty side of things makes it slower I think. Also it is modulated, which breaks up your code into modules that you can load on the page into a div with ajax, preferrably jquery but you can use any framework for that too I can go on forever I maybe will recreate something like that in python, is a good idea, thx GAE is pretty limiting, but I will try to hack it to do things for me anyway. maybe uploading my own libs and import those or upload python into the project, not sure yet, thats why I may go with django -Alex Goretoy http://www.goretoy.com Samuel Beckett - Birth was the death of him.

It doesn't strike me either. But resources are not the only dimension of judging the language, you know. You misunderstand me: I was talking about the resources (people and money) used to create Java. Ah, I see now. From my perspective, it depends on how things ended. Since Java went into VB-like direction, I think I can agree. They have to go deeper and deeper into this... dead end (business decisions and the like). But it wasn't always looking as bad as now, so, you know, it is always easy to judge past, especially knowing that something was a failure. As I was reading about Java's prospects long ago, the use of people and money by Sun seemed like quite good way of spending resources (not best, but justified). In my opinion, it was the direction Java took somewhere around dot com burst that has really sinked it (namely, letting go of innovating aspect and pushing Java as, pardon the word, business-level solution). Java is yet another language with heavy static typing and an object-oriented focus. What should have caused me to waste more time before dismissing it? Really, I don't know. From how you wrote it, seems you had not much need to investigate the subject. So, since you did not feel such need in the first place, it could be difficult to convince you. It really depends on what kind of programs you write (or are going to write). For me, there are some cases, when I would at least consider Java during design phase: 1. Writing code that has to be, umh, mobile (not in a cell phone sense). Working on a network, sending code to other nodes. Special case - when this code has to do some computations, not heavy enough to justify using C, but still enough so that JIT is an advantage (even though JIT may not be available on every node type). And, of course, having a C compiler on every node is not always feasible. My favourites at the moment would be: - Scheme. PLT Scheme has JIT and is my current workhorse language. It is possible to find other Scheme flavors on almost any =32-bit cpu. Cons: all those flavors, albeit very similar and based on well defined common standard - to be frank, not so common anymore, but this is irrelevant - are still a bit different which can get problematic). - Java. Has JIT and is quite ubiquitous, from mainframes to cellphones. Cons: different Java flavors, EE, SE, MIDP... are quite different and their common subset is too simple for my taste. - Python. I like it more than Java, sometimes it is possible to use JIT. Still, the fact that I

I've only read he subject and a few lines from other responses. yes, it is worth learning. I came from PHP to Python.

We think we'd like to trigger an on_load event after a class is fully instantiated (or just a function call for simplicity, so you dont need to worry about our specific system). This is so that if I make a subclass of some widget, I dont have to overwrite the __init__ method (use super, know the args, and pass them) everytime. Maybe I just want to do some really basic stuff that doesn't really have anything to do with the parent class. Anyway. My first attempt was to simply put a call to self.on_load at the end of the widget base class. This doesn't work though, because, if I subclass it and do things after the call to super.__init__, on_load will be called before the constructor finishes (when the top most parent class __init__ finishes) We've sort of managed to achieve this by using a decorator that changes the __init__ function. but even this doesnt seem like the best way to do this. a) I now have to decorate every constructor i ever write. b) it seems impossible to make it so that it only happens once after the object is actually instantiated (since i have a decorator on all my constructors..each constructor in the inheritance line will call on_load once) Can I do something fancy with metaclasses here? I think I could kind of do this by making all my classes use __new__, and then essentially use __init__ as what i want on_load to be...but that just seems really nasty and unpythonic. not to speak about the confusion it would cause with people trying to figure out the library.

somewhere else in my code so can't test this right now, Is this a good
method to do this? or is there another option?

Re: how to repeat function definitions less
i did this because this will read colors into a nested variable How would i make this work the way you suggest? I already have it working now :) Not able to set to dict value with setattr, how to do this too(sorry if off subject)? I can set it like this: for i in self.opt['properties'].keys(): self.opt[i] = getattr(self.opt['properties_object'], i) but not like this: for i in self.opt['properties'].keys(): setattr(self, opt[i], getattr(self.opt['properties_object'], i)) -Alex Goretoy http://www.goretoy.com On Sun, Mar 15, 2009 at 6:41 PM, MRAB goo...@mrabarnett.plus.com wrote: alex goretoy wrote: ok now for the final result, i decided to split options out to a separate dict of lists, does this look right to every one, I currently have error somewhere else in my code so can't test this right now, Is this a good method to do this? or is there another option? [snip] First of all, *don't use is and is not to test for equality*; use == and !=. When you split the options out like that you get duplication.

what is I just set colors: self.opt['arg_opts_options']['imp_colors'] then they are both pointing to the same place, correct? -Alex Goretoy http://www.goretoy.com On Sun, Mar 15, 2009 at 11:16 PM, alex goretoy aleksandr.gore...@gmail.comwrote: i did this because this will read colors into a nested variable How would i make this work the way you suggest?

I think thats what it is. It does look cool, thats for telling me about the

that makes sense to me, where would I read more about python optimizations?

I would imagine that I could do this with a generator and setattr, but I am
still learning how to do that kinda of codingmaybe if I had a dictionary

}

Re: __import__ with dict values
Gabriel, Thank you. This makes sense to me. I will go with sys.modules. Can you give me a good example how to do it getattr way? currently I am having this problem in my code. Kinda off subject, but not entirely. I set default variable in self.opt after that I import jar.properties into self.opt['properties']. Now my self.opt doesn't have the same defaults set. in other words we load our configuration properties. Then we over write any configuration properties with supplied sys.argv[1::] arguments I am passing my sys.argv to a class and inside the class I use getopt to get site_name and files_name, also many other variable that overwrite the configuration that is set from the jar.properties This was working when I was using exec and eval. I was not able to just use exec I had to use exec on import and eval on module.module it was wierd, can someone tell me why? -Alex Goretoy http://www.goretoy.com On Thu, Mar 12, 2009 at 1:00 PM, Gabriel Genellina gagsl-...@yahoo.com.arwrote: En Thu, 12 Mar 2009 09:27:35 -0200, alex goretoy aleksandr.gore...@gmail.com escribió: note i would still like to be able to do __import__(sys).path p = __import__(sys).path That's a convoluted way of doing: import sys p = sys.path (except that the latter one inserts sys in the current namespace) maybe if __import__ had __str__ defined, How is my thinking on this? and how would I achieve something like this? __str__ has absolutely nothing to do. __import__(opt['imp_mod']).options eval(opt['imp_mod']+.+opt['imp_opt']) how to make top work like bottom?

[PyGTK] Singleton Window
Hello All,
I am trying to create a singleton window in pygtk and for the life of me
can't seem to figure out a better way to go about doing this. The way I'm
doing it now is to recreate the window and show it. Example code is below. I
would much appreciate any assistance in this matter. I've googled to no
avail. I'm hiding the child window because when I execute main_quit on the
child it kills parent (which makes sense).
My singleton hack works, but its cluncky, I am wondering if theres some
other way(working shmingleton?).
My question is this. How to create a singleton child window without hiding
old childs(seeing as this creates many hidden childs after a while) or how
to hide it and when showing it again also have it display all contents in
the child window?
Thank you.

Re: best way to serve wsgi with multiple processes
GAE (Google App Engine) uses WSGI for webapps. You don't have to overhead of managing a server and all it's services this way as well. Just manage dns entries. Although, there are limitations depending on your project needs of what libs you need to use. appengine.google.com -Alex Goretoy http://www.goretoy.com On Wed, Feb 11, 2009 at 1:59 PM, Graham Dumpleton graham.dumple...@gmail.com wrote: On Feb 11, 8:50 pm, Robin robi...@gmail.com wrote: Hi, I am building some computational web services using soaplib. This creates a WSGI application. However, since some of these services are computationally intensive, and may be long running, I was looking for a way to use multiple processes. I thought about using multiprocessing.Process manually in the service, but I was a bit worried about how that might interact with a threaded server (I was hoping the thread serving that request could just wait until the child is finished). Also it would be good to keep the services as simple as possible so it's easier for people to write them. I have at the moment the following WSGI structure: TransLogger(URLMap(URLParser(soaplib objects))) although presumably, due to the beauty of WSGI, this shouldn't matter. As I've found with all web-related Python stuff, I'm overwhelmed by the choice and number of alternatives. I've so far been using cherrypy and ajp-wsgi for my testing, but am aware of Spawning, twisted etc. What would be the simplest [quickest to setup and fewest details of the server required - ideally with a simple example] and most reliable [this will eventually be 'in production' as part of a large scientific project] way to host this sort of WSGI with a process-per-request style? In this sort of situation one wouldn't normally do the work in the main web server, but have a separarte long running daemon process embedding mini web server that understands XML-RPC. The main web server would then make XML-RPC requests against the backend daemon process, which would use threading and or queueing to handle the requests. If the work is indeed long running, the backend process would normally just acknowledge the request and not wait. The web page would return and it would be up to user to then somehow occassionally poll web server, manually or by AJAX, to see how progres is going. That is, further XML-RPC requests from main server to backend daemon process asking about progress. I do't believe the suggestions about fastcgi/scgi/ajp/flup or mod_wsgi are really appropriate as you don't want this done in web server processes as then you are at mercy of web server processes being killed or dying when part way through something. Some of these systems will do this if requests take too long. Thus better to offload real work to another process.

Re: best way to serve wsgi with multiple processes
GAE is definitely not suitable in this case... The servers are provided and maintained as part of a large scientific project for which I am providing just a few services... Other groups are running services in other platforms on tomcat through soaplab/instantsoap - but I was hoping to use native python services since I thought it would be easier. OK, that's cool. I understand about project requirements. It was just a suggestion. Nonetheless I'm still interested in what people have to say in this thread. -- http://mail.python.org/mailman/listinfo/python-list

reconstruct html form in pyGTK window and create dict from pyGTK
Hello All,
What would be the best way to fetch a form/s from a webpage and then
recreate it in a pygtk window?
I'm doing some research on this for a project called pynutbutter. This is
for jellpy actually, which handles creating option mappings for pynutbutter
from a GUI.
The things I know I would need some examples on:
How to work multiple glade files? (so i can have multiple pages for
different types of options) more efficient way, is this a good option?
loading of forms fields and reconstructiting in pyGTK with
comboboxes/comboboxtextentry textboxes/textentry and textviews, not how to
load them or display them...I can see that on pygtk websitebut the more
efficient way to do this dynamically.
What is the best way to create a dict from a gui? just have a user type the
dict: somedict={some:thing} or have another window pop up that handles for
name value pairs of the dict and a field for dict name.
After all this what would be the best way for me to merge this dict into a
options file. There will be other options in there. How would I only either
prepend the new dict or if one with same name exists overwrite it. Would
that be a safe move?
What would be the most effiecient and user friendly way to contruct this on
a form basis in a pyGTK GUI
defaults = {formfield:somevalue,anotherfield:somefieldvalue}
mappings =
{somefield:filefield1,anotherfield:some_function(filefield2)}
headers = {filefield1:somefield,filefield2:anotherfield}
What would be the best way for me to construct this dict from a user
friendly form in pyGTK
Sorry this is alot of questions. Any advise on this matter will be greatly
appreciated. Thank you.

PyNutButter BETA 1.0.0 - Automates CSV data Importation into any website http/https and/or mysql database
Introducing PynutButter BETA 1.0.0 Automates csv data importation into any website. Or your money back. Programs like this idea of a program I have here cost $2500. Pynutbutter is opensource. You can use the code anyway you want. As long as I get my credit where it is due. I've worked on this project for roughly 1.5 years now. This is an idea I tried in 2 languages. PHP and python, now. No matter how much data in your csv file. No matter what the field names are. No matter how data is formatted With PyNutButter you can parse this data in custom functions and then send it to its destinations. You can map all the csv file headers to fields of a html page. It loops for each line in the csv file and imports your data. You must configure your configuration and create custom functions that you can call from this configuration. I've uploaded all the main files, except my configuration(I am working on examples and making the main project page better) You can find this project here: http://code.google.com/p/pynutbutter/ I've worked long and hard on this application and the idea behind it. Any help making this tool better would be greatly appreaciated. Please let me know what you this of this tool. Any ideas/features are also always welcome. I also have a presentation I am working on for this tool. I hope to find a nice job. This tools is very powerfuls. I was think next to try it with scapy. That would be sweet. You can add custom flavors(data parsing/sending libraries). My goal for this tool was to make everything as dynamic as possible. calling of functions and dealing with parsed data in functions. Only reason why I built is because I needed a tool like this. I know someone else woulnd't mind having a tool like this either, so here you go. If you can please donate or something somehow.

It's probably because I only downloaded python from svn repo and ran
./configuremakemake install
I didn't do anything else. Like set PYTHONPATH. I solved it though. You can
tell by the output it's looking for it in my other python install lib path.
Thank you.

For packaging, you can choose from a multitude of installer builders - none of which are really Python specific. I'm not even talking about that level of packaging -- I'm just talking about making something that appears to the user like a normal executable, which they can double-click on their system and have it actually run, rather than aborting with something unhelpful like No module named MySQLdb.

Especially when there are significantly way better things out there to feed you mind and your computer. In an unrestrictive so much environment as windows. Especially for development. Sorry this is long and off topic. (I need to learn how to write better.) It's just some things I think about sometimes. Please help me some how to achieve this goal. I want people to really harness the true power of there computer and stop eating BS for applications and development environments. If there is more sand, then there's more sand castles, holes and fun. Why would someone want to pass up the ability to use the same thing in so many more ways than one. It doesn't compute.

Re: math module for Decimals
Hmm. Maybe we shouldn't be using this syntax in from_float, if it's the only thing that prevents the trunk version of decimal.py from being used with Python 2.4. On the other hand, from_float isn't going to work until 2.7 anyway, since it uses a whole bunch of new stuff: as_integer_ratio and copysign (both introduced in 2.6), and bit_length (introduced in 2.7). I so new to python that I'm not sure that anything I can say may help as much as someone with more experience. I would leave is compatability to be decided by what other functions it relies on.(as_integer_ratio and copysign) Throw the rest out the window. Since that would make this function more bulky and I don't think there will be that many people wanting to use it with 2.4, OTOH I'm using BackTrack2 and it comes with python2.4.3 I started building my little program using ubuntu with python2.5.x, then I started to use my other option for dual-boot. Backtrack2 is an old time favorite and is alot faster for me to use when running X,firefox(with anywhere from 15-100 tabs open),konqueror,etc Ialready installed other versions of python for bt, no problem there. I'm just wondering about this import error in decimal.py inside python2.7a0(svn repo), don't let curiosity kill this cat. I just wanted to let All know what decimal.py is doing on my pc. Maybe I'm the only one getting this? This version of python2.7 is from python's svn repo. Is the python repo considered to be unstable(wrong word?) and this is expected? I get this when importing decimal: Python 2.7a0 (trunk:68339M, Jan 5 2009, 05:18:41) [GCC 3.4.6] on linux2 Type help, copyright, credits or license for more information. import decimal Traceback (most recent call last): File stdin, line 1, in module File /usr/local/lib/python2.7/decimal.py, line 138, in module import math as _math ImportError: No module named math Are other people seeing this as well?

Re: threading a 10 lines out of a file
Steve, Are you referring to the endless GIL debate? I googled about what you said. I'll look into it here shortly. I just know one thing, is that I need a comparison for regular code and something about how GIL and threading fit in the picture. It makes it easier for me to understand what is going on. Can you post an example? something I can use to truely thread a for loop? The example previously posted show that it works 10 times faster than original for loop. My current program runs for 4.5 hours. I think it will be good to minimize that by 10 times. But if It can do more/faster, than that would be great. TIA for all your help. -Alex Goretoy http://www.alexgoretoy.com On Mon, Jan 5, 2009 at 6:13 PM, Steve Holden st...@holdenweb.com wrote: re, however, that the CPython implementation won't net you any benefit if all threads are CPU-bound, since due to something called the GIL (global interpreter lock) no two threads will run concurrently. -- http://mail.python.org/mailman/listinfo/python-list
Re: threading a 10 lines out of a file
Se we need to know a bit more about your 4.5-hour program before we can determine whether threads can help. There is light at the end of the tunnel, however, since even if threads don't work it's possible that the multiprocessing module will (assuming you have multi-processor hardware at your disposal). What my program is doing is sending each line to a function that processes it via pycurl(with urllib fallback),mysqlDB(with _mysql fallback). It check the mysql database to see if this line exists. If it doesn't then it sends it either via mysql query or pycurl. Depending on the option set in the functions. Some sections of the function have time.sleep(6) in them. Otherwise things won't work. This considerably slows down performance. If I thread all lines then it will process more at the same time. So that means there will be like 10 or set amount threads running doing all steps in the functions. posting forms, performing queries and waiting for form postings to process on the server, etc... I hope this adds more light at the end of that tunnel. It currently works under my ubuntu install of python(2.5.x) and bt's python(2.4.3). Then reason why I added a fallback to MySQLdb and pycurl is then a person can install this on a server that is hosted elsewhere. Where you can't install python modules, due to permissions and such. I want it to work everywhere. There's alot more to this application, I'm not sure I can disclose at the moment. Seeing as it can be used for good or bad. I don't want it to get in the wrong hands if it's public. OTOH, I think I'll make it public. That's all up in the air at the moment. One thing it that it does make life easier for me. A lot easier. Although, I haven't made money with it. Yet. Plus, I want to make pyGTK frontend for it. Looking into that too. I wouldn't be against a private team assembling to create this though. As long as I can get money out of it somehow. Cuz I'm broke. and I live with my mom. Not sure how anyone can help me there. But I'll throw it up in the air for all to see. Maybe somethings comes out of it. This program is an idea I've been building inside my garage(my room) for about a year and a half. Built in PHP and python, now. Would something that uses pycurl,mysql be good for threading? It doesn't run on SMP but maybe one day. I also need to look into how to make a python package out of it. I researched some stuff awhile ago, but I didn't quite need it then. I just wanted to see what I'm getting into. Any other stuff about this would be appreciated to. Although of topic. Sorry. By the way, I wanted to really thank everyone for all your help. It means a lot to me. -Alex Goretoy http://www.alexgoretoy.com On Mon, Jan 5, 2009 at 9:17 PM, Steve Holden st...@holdenweb.com wrote: I did, once upon a time, write code that used several hundred threads to send emails, and gave a dramatic speed-up (because of the network-bound nature of the task). Can I presume that your original inquiry was a toy, and that your real problem is also IO-bound? Otherwise I am unsure how you will benefit by threading - if your line-processing tasks don't contain any IO then using a threaded approach will not yield any speed-up at all. The example you quoted achieved its speed-up because a thread releases the GIL while waiting for a network response, allowing other threads to process. Thus it effectively ran all the pings in parallel. Se we need to know a bit more about your 4.5-hour program before we can determine whether threads can help.

Re: multiprocessing vs thread performance
There doesn't seem to be any good examples on POSH or it's not clear to me. For when using with a for loop like mk is doing who started this thread. How would somethings like this be possible to do with POSH? The example show how to share variables between processes/threads but nothing about How the thread starts or a for loop. -Alex Goretoy http://www.alexgoretoy.com somebodywhoca...@gmail.com On Sat, Jan 3, 2009 at 1:31 PM, Nick Craig-Wood n...@craig-wood.com wrote: mk mrk...@gmail.com wrote: After reading http://www.python.org/dev/peps/pep-0371/ I was under impression that performance of multiprocessing package is similar to that of thread / threading. However, to familiarize myself with both packages I wrote my own test of spawning and returning 100,000 empty threads or processes (while maintaining at most 100 processes / threads active at any one time), respectively. The results I got are very different from the benchmark quoted in PEP 371. On twin Xeon machine the threaded version executed in 5.54 secs, while multiprocessing version took over 222 secs to complete! Am I doing smth wrong in code below? Yes! The problem with your code is that you never start more than one process at once in the multiprocessing example. Just check ps when it is running and you will see. My conjecture is that this is due to the way fork() works under unix. I think that when the parent forks it yields the CPU to the child. Because you are giving the child effectively no work to do it returns immediately, re-awakening the parent, thus serialising your jobs. If you give the children some work to do you'll see a quite different result. I gave each child time.sleep(1) to do and cut down the total number to 10,000. $ ./test_multiprocessing.py == Process 1000 working == == Process 2000 working == == Process 3000 working == == Process 4000 working == == Process 5000 working == == Process 6000 working == == Process 7000 working == == Process 8000 working == == Process 9000 working == == Process 1 working == === Main thread waiting for all processes to finish === Total time: 101.382129192 $ ./test_threading.py == Thread 1000 working == == Thread 2000 working == == Thread 3000 working == == Thread 4000 working == == Thread 5000 working == == Thread 6000 working == == Thread 7000 working == == Thread 8000 working == == Thread 9000 working == == Thread 1 working == Total time: 100.659118176 So almost identical results and as expected - we ran 10,000 sleep(1)s in 100 seconds so we must have been running 100 simultaneously. If you replace the time.sleep(1) with for _ in xrange(100): pass you get this much more interesting answer on my dual core linux laptop, showing nicely the effect of the contention on the python global interpreter lock and how multiprocessing avoids it. $ ./test_multiprocessing.py == Process 1000 working == == Process 2000 working == == Process 3000 working == == Process 4000 working == == Process 5000 working == == Process 6000 working == == Process 7000 working == == Process 8000 working == == Process 9000 working == == Process 1 working == === Main thread waiting for all processes to finish === Total time: 266.808327913 $ ./test_threading.py == Thread 1000 working == == Thread 2000 working == == Thread 3000 working == == Thread 4000 working == == Thread 5000 working == == Thread 6000 working == == Thread 7000 working == == Thread 8000 working == == Thread 9000 working == == Thread 1 working == Total time: 834.81882 -- Nick Craig-Wood n...@craig-wood.com -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
