Pharo Port
by Udo Schneider 04 May '17

04 May '17

All, I'm currently evaluating the effort needed to port Magma to Pharo. I already am as far as being to able to load all required packages using a configuration (w/o code changes so far ...). Now I'm wondering which Magma/package versions I should best start porting upon? Any hints? I'm also not sure how to deal with breaking changes. Just the fact that Pharo now uses a different file access approach means I have to change core methods (e.g. in Ma-Core in this case). So I can't "just" provide a "Ma*-Something-Pharo" package. And I'm pretty sure that there are other areas where Squeak and Pharo diverged over time ... CU, Udo

Processing objects using Ma Client Server
by Hari Balaraman 27 Apr '17

27 Apr '17

Hi All, I'm struggling with trying to implement conditionality in Server processing. What I am doing now is: myServer processOn: 12345 using: [ :requestObject | [requestObject processThis] fork. responseObject ] This allows processThis to happen and responseObject to come back. What I'd like to do is: myServer processOn: 12345 using: [ :requestObject | [requestObject is MemberOf:A] ifTrue:[(requestObject instVarL)='somevalue' ifTrue:[ ResponseObject1 instVarA:( (requestObject instVarL) ) ].] [requestObject is MemberOf:B] ifTrue:[(requestObject instVarT)='somevalue' ifTrue:[ ResponseObject2 doSomething:(requestObject)].] ] I'd like to get a response without forking.... so that the responseObject is based on the conditionality and the value of one of its instance variables is based on some processing of an instance variable of the requestObject. Is there something structurally wrong with what I am trying to do, i.e. introduce conditionality within the processOn method? Kind regards, Hari

MaObjectSerializer Error: "Incomplete graph, check serializer configuration"
by Hari Balaraman 06 Apr '17

06 Apr '17

Hi All, When attempting to serialise an object within my application, I get the error set out in the subject line, viz., "MaObjectSerializer Error: "Incomplete graph, check serializer configuration" When I have attempted to serialise an object of TestClass1 contained in an object of TestClass2 pursuant to the following class hierarchy: RectangleMorph I_ TestClass1 I_ TestClass2 onto a file in the filesystem, I have no problems. What could be causing the error? If any of the morphs are stepping, would that cause this error? Thanks in advance for all assistance, Hari

Hi Chris et al, I just loaded Ma Client Server on a new Squeak image in Windows 10 and got an error : WindowsOSProcessAccessor does not understand #restoreSigTerm in restartSigTermHandler. It is called by "initialize" and "startUp:" in MaServer. Kind regards, Hari

Fwd: Code Amendment Suggestion
by Hari Balaraman 03 Apr '17

03 Apr '17

Hi Chris, Please find attached, for your review, a fileout to convert a directoryname string into a FileDirectory for the purposes of serialisation by the Ma framework (in case the user sends the method a path as a string.) Kind regards, Hari Balaraman
