[Pharo-project] response to an AJAX POST request
by Bernat Romagosa Sept. 26, 2011

Sept. 26, 2011

Hi lists, I'm trying to get Amber and Pharo to talk to each other by using Ajax. So far, using an Ajax wrapper that Laurent wrote, I managed to get Pharo to receive a message from Amber by doing: |ajax| ajax := (Ajax url: 'http://localhost:4001/amber/'). ajax options at: 'type' put: 'POST'; at: 'data' put: 'Hi Pharo!'; at: 'timeout' put: 500. ajax onSuccessDo: [console log: 'ok!']; onErrorDo: [console log: 'not so ok...']. ajax send This is captured by a Swazoo resource, that does the following: answerTo: aRequest | response | [aRequest postData stream anyDataReady] whileTrue: [Transcript show: aRequest postData stream next]. response := HTTPResponse ok. response contentType: 'text/plain'; entity: 'Done!'. ^response My intention here is just to read the message data and return an OK response, but for some reason stream anyDataReady keeps evaluating to true even when there's no more data to read, so the code underneath is never executed. The Transcript shows 'Hi Pharo!' though, so I'm sure the request is being received and read. Any light shed on this would be of great help... Thanks! -- Bernat Romagosa.

[Pharo-project] I don't understand the GC root table
by Mariano Martinez Peck Sept. 26, 2011

Sept. 26, 2011

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

[Pharo-project] package renaming
by Pavel Krivanek Sept. 26, 2011

Sept. 26, 2011

Hi, do we have some experiences with renaming some of basic system packages in the update stream? Because we will need to rename Morphic package to something like Morphic-Core or so to enable the next Morphic package splitting. Cheers, -- Pavel

[Pharo-project] Class creation notification
by Mariano Martinez Peck Sept. 25, 2011

Sept. 25, 2011

Hi guys. I was checking who needs to be notified when a class is created. If I follow correctly senders of #notify:ofSystemChangesOfItem:change:using: and friends, I don't really find too many listeners. I found TestRunner >> initialize and MCPackageManager -- Mariano http://marianopeck.wordpress.com

[Pharo-project] Fraction>>asFloat needs review
by Nicolas Cellier Sept. 25, 2011

Sept. 25, 2011

After Integer>>asFloat, Fraction>>asFloat needs a review too. It is not broken. But it has unreachable code, performs more arithmetic than necessary and we could put some light on obscure comments and reduce implicit knowledge. So if we can leave a better example of coding in the image, let's do it. It's better to write this in a Blog http://smallissimo.blogspot.com/2011/09/reviewing-fraction-asfloat.html because it would be too long for a single commit comment. Nicolas
