Thank you for the tip. But that also means now I should change my configurations to stay updated because you (doesn't matter who) just couldn't resist copying all NumericalMethods packages to your own repository. This is like if I get 5 mathematicians, fork SciSmalltalk, push cool new features, and then make all you loose them if you don't update. And I could do it for fun 1000 times. You get the idea. But I am not against SciSmalltalk, I don't like forks without a good reason. > "a MetacelloFetchingMCSpecLoader(linear load : > linear load : 0.16 [ConfigurationOfSciSmalltalk] > linear load : 1.0 [ConfigurationOfArbitraryPrecisionFloat] > load : ArbitraryPrecisionFloat-nice.38 > load : ArbitraryPrecisionFloatTests-nice.16 > load : ExtendedNumberParser-nice.1 > load : Math-DHB-Numerical-wernerkassens.30 > load : Math-Tests-DHB-Numerical-wernerkassens.9 > load : Math-DHB-NumericalExtensions-WernerKassens.5)" > this loads additionally ArbitraryPrecisionFloat, but this is, i'd say, an > unimportant bug in the config, that should get repaired occasionally. and > ArbitraryPrecisionFloat is not that big. it's not really a problem. > > >Can you import the ConfigurationOfNumericalMethod from a common > repository in SciSmalltalk? > > there could eventually be a little difficulty. you cant load both > versions.

how to debug zinc server errors from tests

by Martin BÃ¤hr

hi, when debugging a zinc server with tests structured as in http://zn.stfx.eu/zn/build-and-deploy-1st-webapp/ i am wondering how to best debug errors in the server while running tests. one test makes a ZnClient connection to a testserver started from the same test. the test fails with the server returning a 500 error. next i get an opportunity to debug the test, but what i really want is to to debug the server itself. one way is to run the client request manually from the browser, while the real server is in debug mode. that works most of the time, but sometimes it doesn't because there is a difference between the test-server and the real server. i found that i can set the test server into debug mode too, but that is not very satisfying because it causes the test to hang and lock until a timeout is reached and only then the debugger pops up. i'd like the debugger pop up immediately, let me debug and fix the error, and then have the tests proceed. is there a way to do that? greetings, eMBee. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/

smalltalk workshops (building a webserver) after code-in

by Martin BÃ¤hr

hi, Google Code-In is over (i'll probably write more about that later) and there are a few students who have started their path to smalltalk. because there was interest among the students to continue learning, we have started a series of workshops to learn the elements of building a webserver. i have created a screencast for the first topic: FileSystem you can read more about the workshop and find the screencast here: http://societyserver.org/mbaehr/training/Using-the-FileSystem-class-in-Phar… being new to smalltalk myself, there are probably some mistakes, and things that could be done better, however i believe the screencast is usable for learning. i recorded this mostly without interruption except for a few times where i was lost and had to stop and look up what i was going to do. i am open to feedback and criticism of any kind, from pointing out redundant ()s or ways to improve the code to tips for debugging and testing. the next workshop will be saturday the greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/
