Re: [Pharo-users] direct image code exchange

by Juraj Kubelka

Hi! It is great that people are interested in sharing information between images. GTChatter was the first try and we will come with a new solution. What is the most urgent information you want to share between images? Source code? I am curious about your use cases: Do you want to share information between images on the same computer? Between your computers? Between co-workers?

Re: [Pharo-users] MongoDB: console commands? query embedded indexed fields?

by Sabine Manaa

Hi Norbert, Hi Phil, thanks for your help! Now I know what the problem is/was. :-))) The query was right, the index was used, all is fine. BUT: I used an inspector to look at the query's result and opening the inspector forced to load all the other objects which belong to the object found. Explanation: I have a person which has N trips with N receipts, all with back pointers. Opening an Inspector with one trip loads its person and all other trips of this person hahaha. The magritte description isLazy but the inspector forced the loading of the objects in the VOMongoRepository at first time after image starting. Time millisecondsToRun: [(RKATrip selectMany: { 'receipts.receiptDescription' -> 'a' } asDictionary) size] 764 . Time millisecondsToRun: [(RKATrip selectMany: { 'receipts.receiptDescription' -> 'a' } asDictionary) inspect] 17234 So, I messed around with myself. Currently I do not have so much data but I hope in future there will be a lot and I want the application prepared for that. BTW: I found this nice document: https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/ws/Voyage/Vo… I was mentioned there, thanks!

how to reinitialize the jvm in jniport?

Hi, I am trying to shutdown a Jvm instance but when I try to use a new instance, I get a "JNIError: unknown error". Here is what I do on OS X using Pharo 3.0: Gofer new smalltalkhubUser: 'JNIPort' project: 'JNIPort'; configuration; loadVersion: '3.0-baseline'. JNIPortJNIInterface libraryFile: '/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/libclient.dylib'. jvm := JVM newWithDefaultSettings. jvm findClass: 'java.lang.String'. "==> public final java.lang.String Instance class: JavaLangString Static class: StaticJavaLangObject" jvm shutdown. "with or without this line, the below error is the same" anotherJvm := JVM newWithDefaultSettings. ==> "JNIError: unknown error" What am I doing wrong?
