I did an 'Smalltalk allClasses collect:[:cl | cl -> cl allInstances size]' before starting a load and right after a load that just does not crash the image. I noticed the following number of new instances that were still being referenced (i.e. not garbage collected). The following lists the number of _added_ instances during the load with the largest first. I include all of them but some are obviously more indicative than others. Float->3580540 Point->2149989 Rectangle->818991 Array->573089 MorphExtension->309932 TableLayoutProperties->204571 ByteString->108891 OrderedCollection->107527 IdentityDictionary->103768 ImageMorph->102338 StringMorph->102318 Morph->102313 DependentsArray->102309 TableLayout->102308 RowLayout->102259 MorphTreeNodeMorph->102252 PackageTreePackageNodeModel->102250 Association->26405 Duration->14081 CompiledMethod->11191 MethodChangeRecord->11131 IdentitySet->10843 ....

Hi Doru! Download the stable version ConfigurationOfTaskIt stable. We are going through a refactor that adds new concepts, the last code is very unstable.

Re: [Pharo-dev] Pharo and Amber relationship

by kilon alios

yes those are the easy part and I have done them already but for example I don't know how to include amber in my distribution, meaning the Helios IDE. I tried to do that with Github pages and it display the two buttons but it does not open the old or the helios ide. I had to manually comment out gitignore so I can add all ignored folders, but maybe there is more to amber than those folders which would explain why it cannot load Helios. So its definitely not straightforward even for very basic things. But I am willing to learn and contribute. On Sun, Jun 29, 2014 at 4:02 AM, Sean P.

New Cog VMs available

by Eliot Miranda

...in http://www.mirandabanda.org/files/Cog/VM/VM.r3021/. In particular, these fix VM crashes when running the AllocationTest in Spur. CogVM source as per VMMaker.oscog-eem.787/r3021 Fix mixup of old & young spaces in primitiveVMParameter, and comment some new parameters. Fix return types for positive[64/32]BitValueOf:. positive32BitValueOf: must answer a usqInt, positive64BitValueOf: must answer a usqLong. Use positiveMachineIntegerValueOf: to decode arg in primitiveNewWithArg and ensure positiveMachineIntegerValueOf: is inlined there-in. win32: Set the IMAGE_FILE_LARGE_ADDRESS_AWARE flag in the image header of the Windows executables to allow e.g. Spur to allocate more than 2Gb. Spur: Fix sign and overflow issues in instantiating larger objects and determining the size of large instances. Fix some freeChunk accesses that used fetchPointer:ofObject:. Cog ARM: Fix prim return for compileInterpreterPrimitive: on RISCs. On return from interpreter prim, ret pc is in instructionPointer and must return to whence it came, which is the stack on CISC and the LinkReg on RISC. Hence restoring the receiver reg requires different offsets in the two cases. Rework the rotatable quick constant logic a little and clean up users. Fix concretizeMoveRXbrR to do byte not word loads. Fix concretizeConditionalJumpLong: to actually be conditional. Oops. Correct mistaken callersaved reg stuff for ARM Fix concretizedRetN to not over-bump the SP The method abort trampolines shouldn't pop anything, especially now we have the pushLinkreg: arg to manage the LinkReg more easily. Slang: Rip out the UseRightShiftForDivide optimization. It gets unsigned division wrong, and C compilers can and will optimize this correctly themselves. -- best, Eliot

Sharing/Versioning Data

by Sean P. DeNigris

How do we do this now with MC? Are there options other than "encode in string returned by method" like I've seen done for image data? My use case is that I have a very static domain, and so doesn't require user changes. I think the easiest way to distribute it would be to edit the data on a dev image, and then somehow save the data in a way that can be committed with MC so that loading via MetaC config loads the latest version of the data. What would be the best way to do that? Thanks. p.s. on a related note, I'm also interested in distributing static files with the code e.g. maybe a PDF readme ----- Cheers, Sean -- View this message in context: http://forum.world.st/Sharing-Versioning-Data-tp4765528.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
