Why MC when you copying a package doing too much things?
by Igor Stasenko 30 Aug '11

30 Aug '11

If you look how MC copies package from remote repository to package-cache dir, you will find out , that it: - reads and parses all definitions from source package - and then writes all these definitions into a new file while instead it could just simply copy the contents of existing file to the directory and that's it. This actually explains why uploading VMMaker to squeaksource takes ages (and most of the times time outs), simply because on server we have this unnecessary load of read-deserialize-serialize-write cycle while it could be just read-write (copying). I think we could make it faster by copying and then parsing only the necessary parts of package, like commit log and ancestry information, but not parsing the whole package contents. Another approach is of course to split bloated VMMaker package into parts.. but the problem is that for building VMs there's already too many stuff there.. for example look at the configuration of cog: package: 'FFI-Pools' with: 'FFI-Pools-eem.3'; package: 'SharedPool-Speech' with: 'SharedPool-Speech-dtl.2'; package: 'Balloon-Engine-Pools' with: 'Balloon-Engine-Pools-JB.2'; package: 'Alien-Core' with: 'Alien-Core-IgorStasenko.68'; package: 'Sound' with: 'Sound-StephaneDucasse.62'; package: 'VMConstruction-Plugins-OSProcessPlugin' with: 'VMConstruction-Plugins-OSProcessPlugin.oscog-eem.31'; package: 'Freetype-Plugin' with: 'Freetype-Plugin-IgorStasenko.61'; package: 'ObjectiveC-Plugin' with: 'ObjectiveC-Plugin-John M McIntosh.20'; package: 'Cog' with: 'Cog-eem.45'; package: 'VMMaker-oscog' with: 'VMMaker-oscog-IgorStasenko.122'; package: 'Qwaq-VMProfiling-Plugins' with: 'Qwaq-VMProfiling-Plugins-JB.5'; package: 'Applescript-Core' with: 'Applescript-Core-SeanDeNigris.2'; package: 'CMakeVMMaker' with: 'CMakeVMMaker-IgorStasenko.136' ]. but i think we can deal with it nicely. Anyways, i think we should consider splitting VMMaker, because it goes nowhere. For Cog VMMaker , i think we could remove an Interpreter class, which can make a package like 20% smaller, without any need of refactoring and dependency rewiring. -- Best regards, Igor Stasenko AKA sig.

Cog shows around 19M/900K on the same tablet. Unless Android throttles the CPU down. Thank you. This is useful information for me. -- Dimitry Golubovsky Anywhere on the Web

Got network sockets working in Android Cog

The VM just emits a Complex event (see Cross/vm/sq.h and iOS/vm/iPhone/Classes/sqSqueakIPhoneApplication+events.m). > This is modeled very closely on what iOS uses natively. We may want to find a more cross-platform interface, but I have no idea how touch events look in Android. I have no idea either. Besides, my device does not support multitouch. But I see complex events, and if necessary can process them. PS: Bert, I just saw you note about OLPC XO 1.75 which runs Squeak. Just curious what CPU frequency is, what flavor of VM does it run (Cog or Classic) and how much 0 tinyBenchmarks outputs - do you have such details? Thanks. -- Dimitry Golubovsky Anywhere on the Web

Got network sockets working in Android Cog
by Dimitry Golubovsky 30 Aug '11

30 Aug '11

Hi, I got network sockets to work in my Android port of CogVM with PharoCore-13137 image. I made changes to the logic of aioPoll so that it just checks on all handles once and returns if no I/O operations are ready without any looping, otherwise calls all relevant I/O handlers and returns. aioPoll is called as part of ioProcessEvents. I am able to open Monticello repos, download packages, merge, see diffs etc. Socket tests mostly succeeded, 2 failed. One for https (I did not investigate yet how to use SSL in Android NDK, so no surprise it does not work); another is NetNameResolverTest>>testLocalHostName (also failed on PC as I just checked so there is something non-related to Android). I am trying to run the "Software update" item on Pharo. It seems to progress, but very slowly (partly because Squeaksource is very slow from the US). Not sure how long it may take, but I'll try to get it to complete ;) Anyway, this is another step towards release. I have currently these plugins compiled in: BitBltSimulation "BitBltPlugin" BalloonEnginePlugin "B2DPlugin" FileCopyPlugin FilePlugin FloatArrayPlugin FloatMathPlugin JoystickTabletPlugin JPEGReaderPlugin RePlugin SecurityPlugin JPEGReadWriter2Plugin SocketPlugin MiscPrimitivePlugin DeflatePlugin "ZipPlugin" The plugin choice was mostly arbitrary, beyond those really necessary (Balloon Engine, Socket, etc.) What other plugins are worth adding and testing before I start preparing for the release? Thanks. -- Dimitry Golubovsky Anywhere on the Web

VM Maker: VMMaker-dtl.252.mcz

Dave Lewis uploaded a new version of VMMaker to project VM Maker: http://www.squeaksource.com/VMMaker/VMMaker-dtl.252.mcz ==================== Summary ==================== Name: VMMaker-dtl.252 Author: dtl Time: 28 August 2011, 8:47:55 am UUID: 28b5f45a-144a-411f-bede-f25f128f78ae Ancestors: VMMaker-dtl.251 VMMaker 4.7.9 Make NewObjectMemory work with a standard Interpreter. This update provides sufficient support for an Interpreter to run on a NewObjectMemory, rather than the normal Interpreter with ObjectMemory configuration. To reproduce this, make InterpreterPrimitives be a subclass of NewObjectMemory, and disable the error notifiers in CCodeGenerator>>addMethod: and CCodeGenerator>>checkClassForNameConflicts:. The Interpreter/NewObjectMemory configuration is only lightly tested, and may be somewhat slower than the normal Interpreter/ObjectMemory configuration. The purpose of this update is to provide support for StackInterpreter (not yet working) which requires a NewObjectMemory. NewObjectMemory>>clearLeakMakeAndMapAccessibleObjects is temporarily disabled, as it requires support in platforms/Cross/vm/sqHeapMap.c not yet present SVN trunk. There are no changes to standard VM generation with VMMakerTool, which continues to generate a standard Interpreter with ObjectMemory, and there are no functional changes to the standard interpreter VM as a result of this update.

Re: [Vm-dev] Install squeak on BSD x64

Here is my tryings with su: # squeak -display :0 Squeak4.2-10966.image CHECKING cogvm CHECKING squeakvm No protocol specified Could not open display `:0'. # echo $DISPLAY :0.0 # echo $HOME /root # squeak -display :0.0 Squeak4.2-10966.image CHECKING cogvm CHECKING squeakvm No protocol specified Could not open display `:0.0'. But suddenly I asked myself. Why su? And I ran it from my common user console. And It started! I get error window: "Squeak cannot locate the sources file named /usr/local/lib/squeak/4.4.7-2383/SqueakV41.sources". But I see the projects window and can work with it. I need to solve problem with sources file. But this is absolutely another problem. Hurray! Finally we did it! Thanks to everybody! I did not expect to get so friendly supporting and help! Let us make summary of my question (Installing Squeak vm on my platform: FreeBSD 8.2 x64). Ian Piumarta gave the link to tar.gz file with compiled version for my platform. I see a lot of files for different platforms in that location: http://squeakvm.org/unix/release/ What kind of place is it? Who builds this packages? It is a good place to look for certain compiled vm for anybody. I think next time (for example when I will upgrade to FreeBSD 9.0) I will visit this folder first and search necessary package there. * Ian Piumarta <piumarta(a)speakeasy.net> [Sat, 27 Aug 2011 12:34:54 -0700]: > Hello, > > > CHECKING cogvm > > CHECKING squeakvm > > No protocol specified > > Could not open display `(null)'. > > > > May be I must configure squeak somehow? > > I think squeak is working fine. > > The error message indicates a problem with opening the connection to > your X11 display server.

Hallo everybody! I'm trying to install squeak vm on FreeBSD 8.2 x64. kind man Gary Dunn gave me instructions and I report here last results (dialog started in beginners mailing list but I was asked to move my question here). I ran "squeak mySueak.image" from folder where image file resides. The same error: /libexec/ld-elf.so.1: /usr/local/lib/libfreetype.so.9: unsupported Also I've checked version of freetype2 package. It's up to date. What should we do now? So. I still ask to help me. * Gary Dunn <garydunnhi(a)gmail.com> [Wed, 24 Aug 2011 06:08:46 -1000]: > First try cd to the directory containing the image, then execute squeak > ... > eliminate the "path_to_image" part. > > Be sure your ports tree is up to date ,,, you may have an older version > of > freetype. > > The VM just says "i386" which means an Intel rather than PowerPC.

I ran some experiments at ESUG. Here are the results: VM (Jenkins) FFI OSP Applescript Stack Carbon yes yes buggy Stack Cocoa yes no no Jit Cocoa yes no no Jit Carbon yes yes buggy If anyone besides me is using the Applescript plugin, you can replace the buggy one with the one from 4.2.5 (Carbon Interpreter VM; pull the TestOSAPlugin file out of the TestOSAPlugin.bundle).
