There are many questions related to Stackless Python. But none answering this my question, I think (correct me if wrong - please!). There's some buzz about it all the time so I curious to know. What would I use Stackless for? How is it better than CPython? Yes it has green threads (stackless) that allow quickly create many lightweight t...
I've noticed two methods to "message passing". One I've seen Erlang use and the other is from Stackless Python. From what I understand here's the difference Erlang Style - Messages are sent and queued into the mailbox of the receiving process. From there they are removed in a FIFO basis. Once the first process sends the message it is fr...
I am looking for a way to serve HTTP (and do HTTP requests) in an asynchronous, non-blocking fashion. This seems to be hard to do when you’ve decided on Stackless Python 3.1 (also see here for docs) as i did. There are some basic examples, like the pretty informative and detailed article How To Use Linux epoll with Python, and there is...
I have simple map-reduce type algorithm, which I want to implement in python and make use of multiple cores. I read somewhere that threads using native thread module in 2.6 dont make use of multiple cores. is that true? I even implemented it using stackless python however i am getting into weird errors [Update: a quick search showed t...
In my stackless application I'd like to have Erlang style message box queues. Instead of mandating that sending tasklets are blocked until the receiving tasklet is ready to receive, I'd like to have the sending tasklet to queue up the message in the receiver's message box, and be able to wake the receiver if it's sleeping. The sending t...
We're using Twisted extensively for apps requiring a great deal of asynchronous io. There are some cases where stuff is cpu bound instead and for that we spawn a pool of processes to do the work and have a system for managing these across multiple servers as well - all done in Twisted. Works great. The problem is that it's hard to bring...
Stackless Experts, I have managed to create tasklets under Stackless Python (both from the Stackless and the C side). It seems to me that in order to create a tasklet in Stackless, you bind an arbitrary Python callable (function) to the tasklet (as well as the required parameters), so the bound callable would be run as a tasklet. Howev...
How do you implement a stackless language on top of the CLR? What are some issues with implementing a stackless language on top of a stackful virtual machine, and are there any OSS projects out there that have done this kind of work on the CLR? ...
We're building a test harness to push binary messages out on a UDP multicast. The prototype is using the Twisted reactor loop to push out messages, which is achieving just about the level of traffic we require - about 120000 messages per second. We have a 16 cores on our test machine, and obviously I'd like to spread this over those co...
It seems that most new programming languages that have appeared in the last 20 years have been written in C. This makes complete sense as C can be seen as a sort of portable assembly language. But what I'm curious about is whether this has constrained the design of the languages in any way. What prompted my question was thinking about ho...
In Stackless Python in Eve, there is some talk about "BLUE" objects in Python. Does anyone know details about this technology? ...
I have a typical producer, consumer pattern. If the producer sends an object over a channel, the producer is blocked until the consumer accepts the object. After the consumer accepts the object, the producer alters the object in some way. Does the consumer see the object get altered? Or was there an implicit copy when sending the data ov...
Any advantage on stack-less python implentation than Lua's coroutine? What's the difference of them? ...
