New win32 VM available (was: More than 500MB for windows)

by Igor Stasenko

So, after spending unproportionally huge time (2days) dealing with jenkins config idiosyncrasies, it finally managed to build it. http://files.pharo.org/vm/pharo/win/latest.zip This VM should react properly on AddressSpaceLimit=<number of MBytes> setting in .ini file. The ini file is located in same directory as VM executable. If it doesn't exists, you can run VM once and it will create it automatically. Thanks for patience. -- Best regards, Igor Stasenko.

Phexample state keeping

by Norbert Hartl

I'm playing with Phexampe because I think that in my current project the setup of test scenarios will be a huge part of the testing. So do it in a structured way reducing doubled initialization procedures should be something good. I'm just wondering how the state is kept between dependent test cases. A Phexample test case returns a value so that value := self given: #shouldHaveCollectedSomeState transfers the state from the dependent test case into the current. What do you do if the state produced is more complex than a single value? To be honest I don't understand why in a test case that calls #given: a tearDown/setUp cycle is executed between the first and the second test case. I think while using #given: I make the second test case explicitly dependent on the first. Why should I reset state collected by the first before executing the second? I'm a bit reluctant to create new classes for all collected state scenarios so that I can return them properly from one test case to another. Any ideas? thanks, Norbert

If it is for DrGeo, it works on Pharo1.4. But yes, I will wait for its answer.

I am not looking from position of "making customer happy", but "making myself happy", because apparently i am also using same VM and i want it to shine not just from outside, but inside as well. That's why i am grumbling :) So, okay.. i ran following: | objectQuantity objectSize objects fs | objectQuantity := 1024. objectSize := 1024*1024. objects := Array new: objectQuantity. fs := 'allocation.log' asFileReference ensureDeleted writeStream. 1 to: objectQuantity do: [ :index | objects at: index put: (ByteArray new: objectSize). fs nextPutAll: index asString; cr. fs flush ]. and run it on windows, and it actually behaved quite well, at 472 Mb allocated , i got a low-space warning popup. And no ugly crash. (note it cannot be strictly 512Mb, because some space already taken by image + jit + etc.. ) now, i set AddressSpaceLimit=1024 in .ini file and run the same again, and it stopped at 984 (megs allocated), again showing low-space warning (but it took a whiile to show it.. and image responding quite slow.. maybe because i run on virtual box and it is more memory than i gave to boxed windows, so it forced to do a lot of disk swapping. so, it works. -- Best regards, Igor Stasenko.

My use case is simple: I have a normal ComposableModel that has two models - a list and a DynamicComposableModel. The DynamicComposableModel should contain a list of buttons that should change every time the user selects an element in the list.

I've manage to get away by dynamically reconstructing the layout when the selection changes, however it's not that nice because I had to duplicate the layout of the main widget both on the class side and the object side. It would be nice to add a widget to the layout like this: 'aSpec dynamicAdd: modelGetter withSpec: aSymbol ' that would call aSymbol on the object and not on the class.
