[NB] NativeBoost and optCoerceNilToNull
by Max Leske Nov. 17, 2014

Nov. 17, 2014

Once again Iâm struggling with NativeBoost. Iâm trying to use optCoerceNilToNull with this function: ^self call: #(LGitReturnCodeEnum git_commit_create( LGitId * theCommitId, LGitRepository repo, String update_ref, LGitSignature * theAuthor, LGitSignature * theCommitter, String message_encoding, String theMessage, LGitTree theTree, int parent_count, LGitCommit * parentsPointer)) options: #( optCoerceNilToNull ) The last argument can be NULL, per documentation, (no parents). LGitCommit is a subclass of NBExternalObject and apparently NBExternalObjctType>>pushAsPointer: does *not* use the optCoerceNilToNull option (the super implementation in NBExternalType>>pushAsPointer: however does). The upshot of course is that the call fails with âan instance of LGitCommit expectedâ. My questions: - The documentation says: "#optCoerceNilToNull" "passing nil as a pointer-type argument, converts it to C NULL â but apparently this doesnât apply to every pointer type. Should the documentation be updated? - Why does NBExternlObjectType not use optCoerceNilToNull? I donât want to use tricks to pass null if I donât have to. - Related: there are instances where even non-pointer arguments are allowed to be NULL. Why does optCoerceNilToNull only work for pointer types? Igor! Help! :) Cheers, Max

Julia vs Pharo
by Serge Stinckwich Nov. 17, 2014

Nov. 17, 2014

Hi all, I find a recent paper about Julia that might be appealing for people interested in doing scientific computation in Pharo (like the SciSmalltalk community) : http://arxiv.org/pdf/1411.1607v1.pdf "Julia: A fresh approach to numerical computing" Julia is a new dynamic programming language for scientific programming with much higher performance than R or Python. I found that some concepts are quite closed to Pharo in fact: - meta-programming and code generation - arbitrary precision integer - JIT compiler (based on LLVM) - call to C API What is missing in Pharo at the moment: - multiple dispatch - arbitrary precision float - dynamic dataflow type inference - optional type annotations (maybe with pluggable type extensions for Pharo ?) - special matrices types like spares or dense matrix, tri-diagonal, etc ... - vectorization Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Help fight Ebola by joining the Computing for Ebola Challenge http://bit.ly/1oEdBag

Reproducible VM crash with excessive garbage collection
by Max Leske Nov. 17, 2014

Nov. 17, 2014

Hi. I may have discovered a bug in the PharoVM (stable and latest), which may have been around for at least two years (I had a very similiar situation about two years ago with Fuel). I have a test that fails when a particular method contains â3 timesRepeat: [ Smalltalk garbageCollect ]â. In order to be sure that itâ not the #timesRepeat message thatâs causing the crash, I replaced that with multiple âSmalltalk garbageCollectâ sends. The test Iâm talking about ObsoleteTest>>testFixObsoleteSharedPools. To make the test crash the VM, simply add a couple of garbageCollects at the end of SmalltalkImage>>fixObsoleteSharedPools. I tried to come up with a little script to demonstrate the issue but I can only reproduce the problem with Nautilus (which makes me suspect that the problem is related to Nautilus). Steps to reproduce: 1. get a fresh image and the latest vm: curl get.pharo.org/40+vmLastest <http://get.pharo.org/40+vmLastest> | bash && ./pharo-ui Pharo.image 2. open the class browser and navigate to SmalltalkImage>>fixObsoleteSharedPools 3. Append ten âself garbageCollectâ statements to the method. 4. navigate to ObsoleteTest>>testFixObsoleteSharedPools and click on the test runner icon to the left of the method name. I can reproduce this with the Mac VM (OS X 10.10) as well as with the linux VM (Ubuntu 12.04.1). Iâve opened an issue for this: https://pharo.fogbugz.com/f/cases/14478/Reproducible-VM-crash-with-excessiv… <https://pharo.fogbugz.com/f/cases/14478/Reproducible-VM-crash-with-excessiv…> Cheers, Max
