Re: [Pharo-project] response to an AJAX POST request

by Bernat Romagosa

Thanks guys! I read that Mozilla link, and it seems you just need to tell the server to respond that the origin URL is allowed to send requests to the server. I asked Janko how to do that and the following line was enough: response addHeaderName: 'Access-Control-Allow-Origin' value: ' http://localhost:4000/'. Now Amber can send data to Pharo and receive a valid response.

[Pharo-project] I don't understand the GC root table

by Mariano Martinez Peck

Hi guys. I usually thought that the root table of the GC was the #specialObjectsArray. Now, checking a little bit the VM and image side, it seems I am totally wrong. "Smalltalk rootTable" answers an array that I cannot understand how such array can be the root. Where are the references to all the system from such an array? there is no reference to specialObjectsArray for example. Even more, the table seems to be full of weird stuff, such as "an OController", a lot of "a Text" instances about my workspaces stuff, Colors, Morhpic, etc.... Smalltalk isRoot: Smalltalk specialObjectsArray -> false Smalltalk isRoot: true -> false Smalltalk isRoot: false -> false Smalltalk isRoot: nil -> false so...I am lost. Thanks in advance for any help. -- Mariano http://marianopeck.wordpress.com

Be sure to use last version. Here it loads: Deprecation raiseWarning: false. Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfCog'; load.

In Seaside 3.0 you find a method on the class-side of WADevelopment that takes care of everything. It has no dependencies, so you can just copy it from there.
