Seaside and Fuel

by Jeff Gray

I am writing a Seaside application which will have a modest set of data to be persisted. I would like to use Fuel for the persistance, for its simplicity. I assume that Fuel will be a "load all data into memory" and "save all data back to disk" sort of a model. If so, I 'm wondering where I should do this in my code. I can attach the "load" to the entry page but the "save" is more tricky. Would it make more sense to attach these to start up and close down of the image? What do you reckon (or am I thinking about this all wrong)? -- View this message in context: http://forum.world.st/Seaside-and-Fuel-tp4075405p4075405.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

You're probably better off asking this on the Seaside list.

WAFile or link to file

by Foxugly

Hi, I have a problem with WAFile, upload/download files. Of course i know this link : http://book.seaside.st/book/fundamentals/forms/fileupload but in my project I have to import/export all the datas and files and so I lose my WAFile objects So, is it possible to create a WAFile without the web interface (so without html uploadFile) or do you know how to make a link to an existing file on the server. can you help me ? best regards Renaud Vilain

I am using multiple Smalltalk server instances/images behind a non-Smalltalk (Apache 2 in my case) load balancer. Current VMs are single core, so to use the multiple cores on modern machines, this is useful. Given the amount of memory you get today, you can better use it, and Smalltalk is very efficient compared to say Java. This kind of setup also allows for a more resilient system since requests can be routed around a crash in a worker. There exist server tools (like monit) that monitor your workers and restart them automatically when needed. The challenge is of course to build a system that is either stateless or where the shared state lives efficiently outsite each worker. Sven

I guess that sven is using pharo to manage multiple servers using a rest like architecture.

Hi Offray, I'm afraid none of these would suite very well. The usual approach for a webserver in Pharo is to put it behind a Nginx/Apache/etc (as with your Rails or Zope). I don't know anyone who is using a Pharo server to load balance other applications but I'm maybe wrong.

When you take over mouse handling, you lose the standard "pick up morph" behavior. Glad you got some use out of it!

Changing Cherokee for a Smalltalk based web server?

by Offray Vladimir Luna CÃ¡rdenas

Hi all, I'm getting random "504 gateway error" answers from several sites (using Zope and Rails) that are served by Cherokee using a reverse proxy setup. This error is an open issue in Cherokee and has been reported and not properly patched since 2009: https://code.google.com/p/cherokee/issues/detail?id=504 I did choose Cherokee because of its easiness to setup and newbie friendly interface and character, but with this problem I'm thinking in testing another server, may be a Smalltalk based one that have similar characteristics and can serve sites in Zope or Rails also. I know about Comanche, Swazoo and Zinc, but I don't know which of them is better (making load balance and stuff like that) and have proper documentation about using it in combination with other software (Zope and Rails in my case). Any advice on this matter is greatly appreciated, Offray
