[Pharo-project] So I broke 8k req/s today
by Philippe Marschall Feb. 27, 2012

Feb. 27, 2012

Hi I heighten everybody's mood I'll post some positive news. After some optimizations in both Seaside and AJP I managed to break 8000 requests / sec with a single Pharo 1.3 image. Thanks to SystemProfiler I knew where to look. This is with a single request handler that just returns a two byte response. It doesn't involve any rendering, sessions, continuations or whatsoever but it kicks on the full Seaside request handling machinery with a request context and everything. I'm using WASmallRequestHandler from the Seaside-Benchmark package. WASmallRequestHandler >> #handleFiltered: aRequestContext aRequestContext respond: [ :response | response binary; contentType: WAMimeType textHtml; nextPutAll: 'OK' asByteArray ] Apache 2.2.21 mpm_worker mod_proxy_ajp CPU Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz SmalltalkImage current vmVersion 'Croquet Closure Cog VM [CoInterpreter VMMaker.oscog-eem.138]' Attached you'll find the output of ApacheBench. Cheers Philippe

[Pharo-project] [JOB, Academia] PhD Position at INRIA Lille
by Marcus Denker Feb. 27, 2012

Feb. 27, 2012

INRIA has a new call for PhD Student positions. Description ============ To support the creation and evolution of complex systems, dynamic languages provide support for reflection. A reflective system contains a model of itself to enable runtime change: if we change the model, the system changes and vice versa. Reflection allows the programmer to do any kind of change at runtime, even those that render the system useless or breach any kind of security guarantees. Reflection is an established research theme and has seen a lot of work over the last decades. The question of how to control reflection and related that of secure reflective systems in general has not seen much research activity. The goal of this PhD is to propose a new secure reflective language kernel for dynamic languages. The following points should be explored: - Study existing models of security. - Study existing reflective systems and especially prior work on security and reflection. - Propose a new, secure model of reflection. - Implemented the model in a dynamic, object-oriented language.

Hi guys This version of ecompletion will work on pharo1.4 (i.e. enhanced shout packages) and new text editor (so cool). MCHttpRepository location: 'http://ss3.gemstone.com/ss/NEC' user: '' password: '' Feedback is welcome of course. I'm currently renaming the classes to avoid clashes and I will clean it a bit and check OCompletion. Stef

[Pharo-project] Misc. newbie questions
by Gerry Weaver Feb. 27, 2012

Feb. 27, 2012

Hello All, Firstly, let me say that I am enjoying Pharo very much at this point. I wish I would have found the time to look at this a long time ago. I have a few misc. newbie questions.Â 1. VisualWorks - I am doing a lot of thinking about projects that I could use Smalltalk on. I have a consulting project coming up that might be a good candidate, but I'm sure I would be required to use a commercial Smalltalk version for it. I guess it may be odd to ask about VisualWorks on this list, but I'm not really looking for a comparison to Pharo. What I'm interested in is your opinion of the product. I would like to know if any of you would consider using it on a project. I would appreciate anything y'all could share in the form of experiences good or bad. I am trying to get my hands on it, but Cincom's mail server (windoze) is having issues. I am also having some trouble getting pricing out of them. Anyway, I would like to get your take on the Cincom products. 2. There appear to be some tool choices in the Pharo image. I would like to be able to create a class and it's methods in an editor in one go. I like being able to see all of the class code at once. Is there a way to do this? Â I just want to be able to type it all in and accept (evaluate?) all at once. 3. I've seen some discussion about images and image sizes. What is the current state of this. Is it possible to strip an image down to just the required components for an application (ie; no world menu, etc.). I would like to be able to run an image that would bring my gui application up filling the image window such that it looks a close as possible to a conventional gui application. 4. I have been reading about something called "Opentalk". It is a way for images to be able to comminucate with each other over the network. I've also seen something callesd "rST" that appears to do a similar thing. In addition, I notice that someone has done some FFI bindings for zeromq. What would y'all recommend as the best option to achieve something like this in Pharo? 5. I'm trying to figure out exactly what the Pharo gui toolkit provides in the way of widgets. Is there a widget gallery type thing somewhere that shows all of them? I know I can play with them in the image, but it would be nice to see a list of what is there with a brief description. 6. I know Pharo doesn't currently support OS threads in an image, but I'm wondering about the FFI. Is it possible to call a foreign function in a separate OS thread or asynchronously in Pharo? Disclaimer: I'm not asking for any how to type answers here. I can do the reading and experimentation myself. I just want to know if these things are possible and where to start looking for a solution.Â Thanks, Gerry
