NativeBoost VM crash
by Holger Freyther July 23, 2015

July 23, 2015

Hi, I have a class that calls RAND_bytes in libcrypto and I am (mis-?)using NativeBoost for that. The function appears to work in general and I can make 1000000 calls in a row. I am now invoking (RAND bytes: 4) asInteger from within and then get crashes if I insert enough (10000) objects. Iâm using a Pharo3 image with todays Pharo-vm-mac-latest and it is easily reproducible. I am not sure if that is before or after the C code has been called but the frame just looks invalid (hence invalid). I had a breakpoint in the initial call to RAND_bytes and looked at the âtrampolineâ, at the time it is crashing the frame is a different one and the original is gone (disassembles to something different) . Am I using NativeBoost correctly here? Do you have any hints? Is the code moving or being garbage collected? Is there an easy way I could proof the theory? kind regards holger Details * thread #1: tid = 0x120dae, 0x21a70140, queue = 'com.apple.main-thread', stop reason = signal SIGILL frame #0: 0x21a70140 -> 0x21a70140: negl %esp 0x21a70142: addl -0xc(%ebp), %esp 0x21a70145: movl 0xada30, %eax 0x21a7014b: movl (%eax), %eax (lldb) register read General Purpose Registers: eax = 0x21a70110 ebx = 0x000000e8 ecx = 0x00000002 edx = 0x0000000f edi = 0x21a7010c esi = 0x21a70131 ebp = 0xbffacb38 esp = 0x00000008 ss = 0x00000023 eflags = 0x00000202 eip = 0x21a70140 cs = 0x0000001b ds = 0x00000023 es = 0x00000023 fs = 0x00000000 gs = 0x0000000f (lldb) bt * thread #1: tid = 0x120dae, 0x21a70140, queue = 'com.apple.main-thread', stop reason = signal SIGILL * frame #0: 0x21a70140 frame #1: 0x0009827b Pharo`primitiveNativeCall + 107 frame #2: 0x1f400780 (lldb) di -f -> 0x21a70140: negl %esp 0x21a70142: addl -0xc(%ebp), %esp 0x21a70145: movl 0xada30, %eax 0x21a7014b: movl (%eax), %eax 0x21a7014d: movl %esp, -0x10(%ebp) 0x21a70150: subl $0x4, %esp 0x21a70153: andl $0xf, %esp 0x21a70156: negl %esp 0x21a70158: addl -0x10(%ebp), %esp 0x21a7015b: pushl %eax Object subclass: #RAND instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Hack'!

Contributing to VoyageMongo (improving insertion/updating speed)
by Holger Freyther July 23, 2015

July 23, 2015

Hi, I wanted to benchmark some look-ups with VoyageMongo and tried to insert some dummy objects and it was quite slow (pharo takes 99% CPU and mongo is idle). Using the nice profiler i noticed that VOMongoRepository>>#newVersion calls UUIDGenerator new makeSeed which will take quite long. [UUIDGenerator new makeSeed] bench '96.9 per second.â I am running this on OSX so it will end up in >>#makeUnixSeed which will open /dev/urandom. I needed cryptographic random numbers in another project and used NativeBoost to call into libcrypto of OpenSSL and use the RAND_bytes function to get them. [ (RAND rand: 4) asInteger ] bench '588,000 per second.â The quality of the random numbers should be comparable and now I wonder how I can help integrating such a change. >From my point of view I can either patch Voyage-Mongo-Core to be able to use other random number sources. Or I could add another âseedâ source to the UUIDGenerator. What would be the preferred approach and how to move forward? Is NativeBoost something one could rely on in upcoming Pharo versions? For a simple insertion of a class with a couple (~5) fields the insertion time for 1000 items goes from ~10s to ~250ms. How can I move this forward? holger

Hello, I have been working in making a exporter from blender into a custom JSON format for Woden with support for animations. Here I made a short video: https://www.youtube.com/watch?v=HQpaeDQ3TBM&feature=youtu.be I also made a new shader management system for Woden, so I took the opportunity for adding support for parallax occlusion mapping: https://www.youtube.com/watch?v=fFf7v37j8xg&feature=youtu.be Greetings, Ronie

MongoTalk: new place on smalltalkhub
by FranÃ§ois Stephany July 23, 2015

July 23, 2015

Hi, I've just created a new team for MongoTalk on SmalltalkHub: http://www.smalltalkhub.com/#!/~MongoTalkTeam The old repo (http://www.smalltalkhub.com/#!/~francois/MongoTalk) will stay just in case some scripts rely on it but you should update to the new repo: http://www.smalltalkhub.com/#!/~MongoTalkTeam/mongotalk I've created a version 1.5.1 in the Metacello configuration to reflect the repo migration. Shout at me if I missed something! Cheers, Fa (Many thanks to Norbert for pushing the migration ;)

Seeking help to resolve startup error on CI automated build
by Jigyasa Grover July 23, 2015

July 23, 2015

HiI am trying to build my first application in Pharo i.e. an offline text search application namely *searchQuick* which returns the list of file titles from the pre-loaded text files present in the resource folder when a string is searched for. You all are welcome to fork the code (https://github.com/jig08/sQuick_new) , try the infancy application and send in suggestions. Currently, I have put my application up on CI for automated build. I am currently getting a StartUp error on VERSION=development (40) The error is as follows: *The symbolic version '0.1-baseline' is not defined in ConfigurationOfsQuick_new for the current platform. Possible symbolic version values include: #(#bleedingEdge #development #stable)* I have checked ConfigurationOfsQuick_new and the corresponding method reads as follows:*------------------------------------------------------ development: spec <symbolicVersion: #'development'> spec for: #'common' version: '0.1-baseline'*.*------------------------------------------------------* It would be great if my mistake is pin-pointed and I could resolve it. Thanks and Regards Jigyasa
