Unfortunately ApacheBench uses exactly this. Correcting this was easy: Swazoo patch to allow Keep Alive (ab -k) over HTTP 1.0: HTTPConnection>>getAndDispatchMessages ... (self task request isHttp10 and: [self task request isKeepAlive not]) ifTrue: [self close]. ... Best regards Janko -- Janko MivÅ¡ek Aida/Web Smalltalk Web Application Server http://www.aidaweb.si

Re: [Pharo-project] New IDE alternative (was Misc. newbie questions)

by S Krish

Can take the latest of the package.. PackageTree-Browser-Experiment * Find class added and a crude/ workable expand for text morph.. As stated in the comments: will require a hack in Pharo 1.4 for now. Will work towards integrating TabbedPane with TWM/ this too as an addon with more complete features month ahead.

One thing I noted with testing Swazoo is that is doesn't support Keep-Alive with HTTP 1.0. Unfortunately ApacheBench uses exactly this. Cheers Philippe

I'm preparing a similar benchmark including the comparison with VW, so that we can see how Pharo is progressing on network field and also in general.

Re: [Pharo-project] Are Objects really hard?

by Janko MivÅ¡ek

Hi guys, Just to conclude this topic: there is a nice talk between Dave Thomas (of OTI fame where IBM VisualAge Smalltalk and nowadays VA Smalltalk came out), James Robertson and David Buck in recent Independent Misinterpretations: IM 67: Have Objects Failed Us? http://www.jarober.com/blog/blogView?entry=3507708198 What I like is a discussion about OO vs. relational world and ORM in the second half, which is also by my opinion the reason why OO didn't succeed more as it did, and why is considered hard for most of developers until our days.

I got a feeling when I messed around with SCGI that it can also matter "how" the frontend works against the backend. regards, GÃ¶ran

No, I build my own buffer and go straight to Socket. AJP is packet oriented with 8k packets so this is easy. Cheers Philippe

Hi Philippe! Nice to see your AJP work giving results! I think Nginx has a module for AJP, would be interesting to see if that makes a difference. :) Are you using stock SocketStream internally or anything even more bare bone? regards, GÃ¶ran

Re: [Pharo-project] eCompletion working in latest 1.4

by StÃ©phane Ducasse

Doru I published a new version called NEC. Now it works :) Please use this one. I will create a configurationOf so that you can work safely with it. The idea is to get it clean and be able to thing how OC can be plugged into it without copying everything. Now the extensions have been folded in their packages when it made sense and this is nicer.
