[Pharo-project] why (MCPackage named: 'NonExistenPackage') unload. doesnt fail ?
by Mariano Martinez Peck Jan. 6, 2011

Jan. 6, 2011

Do we want that? I am finding a lot of outdated code that uses code like that and it doesnt fail, but still doesnt unload the package. For example, cleanUpForRelease does a (MCPackage named: 'HelpSystem') unload. and that package doesnt exist anymore since it was split.... so...do we want that silent behaviour ? cheers mariano

[Pharo-project] Another Design Question - SOAP and WSDL - Subclass or not XMLElement
by CÃ©drick BÃ©ler Jan. 6, 2011

Jan. 6, 2011

Hi there, While doing my experiments with SOAP and friends, I've come to the conclusion, I'll redo mainly SOAP because previous implementation is linked to an independent XML representation. I find XMLSupport very nice in design and well documented so I consider it as a basis for implementing SOAP (to me it's a really good example of package as they should be). But there come the design question. To me SOAP elements are particular XMLDocument and XMLElement. Indeed, I found the interfaces of java 6 which was quite what I have in mind [1]. I think the main problem (to me) is that XMLElement in Smalltalk has an inst var containing all children node. I think this is different in java. The consequence is to model SOAPEnvelope (subclass of XMLElement), I can't really add a body and header field respectively for the SOAPHeader and SOAPBody object. Instead I should put them in the children collection node. Is it a good practice ? Do I use a factory to ensure there's at least one and only one body and eventually a header ? Any other pattern for such situations ? Or would you avoid to subclass ? Secondary question: As I found this java API, I got really tempted to use a similar organization. It it authorized ? I couldn't really parse the license file :) Thanks in advance, CÃ©drick [1] http://download.oracle.com/javase/6/docs/api/javax/xml/soap/

[Pharo-project] controlling the size of a morph embedded in a morphtreemorph
by Tudor Girba Jan. 6, 2011

Jan. 6, 2011

Hi (Alain :)), I am trying to embed morphs into a MorphTreeMorph, but I cannot seem to be able to control the size. Please take a look at the screenshot in the attachment. On the right hand side I have a tree morph that lists all methods, and when I expand a selector, I see the source code. Now, I would like to have the followings: - the text morph fill the entire horizontal space - the text morph expand on the vertical, too - the label fill the entire horizontal space I tried to: - set the MorphTreeMorph to have lastColumnUnbounded, and - the morph layout to (fullFrame: (LayoutFrame fractions: (0 @ 0 corner: 1 @ 1))) but it did not work. Does anyone have an idea? If you want to take a look at the example, you need Glamour: Gofer new squeaksource: 'Glamour'; package: 'ConfigurationOfGlamour'; load. (Smalltalk at: #ConfigurationOfGlamour) perform: #loadDefault. and then: GLMOtherExamples new expander openOn: Collection withAllSubclasses.

[Pharo-project] [ANN] Amazon AWS S3 Client
by Sven Van Caekenberghe Jan. 6, 2011

Jan. 6, 2011

Hi All, I implemented and published a Pharo client for Amazon's AWS S3 service called ZnAWSS3Client. For some background, see http://en.wikipedia.org/wiki/Amazon_S3 or http://aws.amazon.com/s3. The code can be found in the package 'Zinc-AWS' in http://www.squeaksource.com/ZincHTTPComponents.html. It depends on both Zinc HTTP Components and XML Support (an excellent package BTW) as well as on the cryptography functionality in Pharo (md5, sha1 & hmac). Basically, Amazon S3 (Simple Storage Service) is an online storage web service where you store and retrieve objects under keys organized in groups called buckets. Objects can be any web resource identified by a mime type. The main advantage is that S3 is a highly scalable, reliable, secure, fast, inexpensive service. The client is currently a proof of concept implementing the basic S3 concepts. Here is some example usage: | client | (client := ZnAWSS3Client new) accessKeyId: '2ZGSSBGBHQGJ9VV5N441'; secretAccessKey: 'OtxrzxIsfpFjA7SwPzILwy8Bw21TLhquhboDYROV'; checkIntegrity: true. client buckets. client keysIn: 'my-bucket'. client keysIn: 'my-bucket' query: (Dictionary with: 'prefix'->'my-'). client at: 'my-bucket' -> 'my-key'. client at: 'my-bucket' -> 'my-key' put: (ZnEntity with: '0123456789'). client at: 'my-bucket' -> 'my-key' put: (ZnEntity with: 'Smalltalk rules S3!') headers: (Dictionary with: 'x-amz-acl'->'public-read'). Sven PS: the code does contain comments but you will need to read up on S3 first. To run anything you will have to create an AWS S3 account.

[Pharo-project] Alien and callbacks from "foreign" threads?
by Joachim Geidel Jan. 6, 2011

Jan. 6, 2011

Hi everybody, I am close to releasing JNIPort (http://jniport.wikispaces.com) for Pharo and Squeak. Almost everything works on both Mac OS X and Windows with one exception. I can attach a Java VM to Pharo/Squeak, I can send messages to Java objects and get results back, and even callbacks from Java to Smalltalk seem to work. The exception is that a callback from Java to Smalltalk which comes from a different thread leads to a crash of the Squeak VM. I have not been able to figure out what the problem is. There is a similar problem with a hook of the Java VM: one can register a callback function which is called whenever the Java VM produces output for stdout/stderr. With Pharo 1.1.1 on Mac OS X, using this hook works when the hook contains a "nil halt", and if I simply proceed in each of the notifiers. When I remove the halt or replace it by a Delay, the image freezes. In Squeak 4.1 on Windows, the behavior is different: the VM crashes. Does Alien support callbacks coming from a "foreign" thread? Or is this a limitation of Alien? Thanks in advance for any help, Joachim Geidel -- View this message in context: http://forum.world.st/Alien-and-callbacks-from-foreign-threads-tp3175989p31… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Yes. He used the term correctly, because the decided titles were PharoCore for core, and Pharo for core+tools :) Cheers, Doru On 5 Jan 2011, at 23:12, StÃ©phane Ducasse wrote: > do you mean in Pharo-dev? > > On Jan 5, 2011, at 6:39 PM, Alexandre Bergel wrote: > >> I had a quick look at it. >> In Pharo 1.2, the XML-Parser parkage is clean (i.e.,not dirty).

[Pharo-project] about cleaning undo
by Mariano Martinez Peck Jan. 5, 2011

Jan. 5, 2011

Hi alain. In #cleanUpForRelease of Pharo 1.1 we did at some point a Smalltalk cleanUpUndoCommands. Now in pharo 1.2 this is removed. I guess it is because of the new undo framework? in such case, there insn't anything to be cleaned ? thanks mariano
