[Pharo-project] Pharo Core HTTP Server OneCommandLine Demo

by Sven Van Caekenberghe

How easy and how fast can you download, install and start an complete Pharo Core based HTTP Server on a bare Linux machine ? It just takes OneCommandLine: $ curl http://zn.stfx.eu/zn/pharo-server.sh | bash In well under a minute (in 11 seconds below, actually), you can browse http://localhost:1701 and all this with way less than 20Mb being downloaded. Mind you, this is quick hack, for some this will be old news, for others I hope this feels like magic. Some notes: - pharo-server.sh will download, install and start a Pharo Smalltalk HTTP server - this script needs bash, curl, tar, unzip, at least, and was only tested on Ubuntu - no special permissions needed, all files will reside in ~/pharo-server - you will probably have to allow 1701 as a TCP port in your firewall for external access - technically, the most interesting thing is the script called st-exec.sh - you have to trust me that the installer is well-behaved, or have a look yourself ;-) Next is a terminal log of running this script, at the end there is a small benchmark showing what kind of performance you can expect from this setup (saving the best for last). The machine in question is an Amazon EC2 micro instance, the smallest, least powerful that you can get.

Why? Your conclusion makes no sense to me. Nautilus and all the browsers built by benjamin and will (with some adaptation) manipulate: compiledMethod class methodReference and their ring counterparts. So I do not see why you cannot do the same. There is no magic read the paper. Stef

[Pharo-project] a nice quote

Hi I was reading a book on risk management :) and I loved the quote: Progresser c'est changer d'erreurs. Making progress is changing of errors. Stef

> There is something wrong, I just took the build #650 and loaded your commit Zinc-Seaside-lr.17.mcz, created a new Zn adaptor, saved the image and quit: now the image refuses to start! I cannot reproduce, but one thing that seems strange with Zinc is that when I stop the server it actually takes 10 to 20 seconds for the site to stop responding ... :-/ Lukas -- Lukas Renggli www.lukas-renggli.ch

I don't think that the server manager calls #basicStop/#basicStart on startup/shutdown (this is when you explicitly start/stop the server), only #startUp/#shutDown. I might be wrong though ...

by Igor Stasenko

@Torsten, i cloned Cog/blessed repository to new one, called pharo-vm https://gitorious.org/+pharo-developers/cogvm/pharo-vm which will serve as a repository for branded pharo-vm. Now what you can do is to register on gitorious, make own clone of this repository and start adding necessary files. or just register without making own clone, i will add you into pharo-developers group so you can commit directly to this repository. -- Best regards, Igor Stasenko AKA sig.
