[Pharo-project] threads using NativeBoost
by Lawson English Aug. 1, 2012

Aug. 1, 2012

I'm to the point now where I want to try to call a library from NativeBoost in its own thread. Has anyone tried this? are there are any guidelines for threaded external libraries? Are there issues that would make this more difficult? Etc. Basically, I've got a mandelbrot set lib I'm playing with. It uses doubles for its default rendering, which means a 1K x 1K image can rander in .3 seconds. Evoking such a library would cause a rather dramatic delay, but when I move to arbitrary precision libraries, where drawing can take many seconds or even minutes/hours/days/weeks/etc, a dramatic delay would turn into a completely frozen VM, which is why I need to use threading. I only need one thread, but want to know if there are issues that might bite me at unexpected moments. Thanks.

[Pharo-project] how can we commit the configuration of rb to the refactoring browser repository
by StÃ©phane Ducasse Aug. 1, 2012

Aug. 1, 2012

Hi guys Configuration should not be only in metacello repository. Think objects! Now how can we commit the configuration of rb to the refactoring browser repository? should we fork it for real. I think that we should migrate from squeak source really soon now. Stef

[Pharo-project] double elements in diff morph?
by Esteban Lorenzano Aug. 1, 2012

Aug. 1, 2012

Hi, Since some days I'm often seeing that merge tool shows duplicated entries... I'm not sure why that happens and how... Can someone confirm the problem? If it is there... does anyone has an idea of why can that be happening? thanks, Esteban

[Pharo-project] Going meta (VM development)
by Igor Stasenko Aug. 1, 2012

Aug. 1, 2012

Hello, spent another day building VM, i found that our setup is still far from being simple.. the jenkins jobs right now using a page-long scripts to configure & build vm, and grown with many bells and whistless.. one of my goals when i created a configurations was to avoid that.. and keep these things 1-liners.. one of the reasons for doing that is that you can reproduce the whole build on local machine from command line by typing a simple commands like make , as well as simple doits in VMMaker image. So, here some of my suggestions: - create a single PharoVMBuilder class, which will encompass all the details of platform-specificness, and will pick the right configuration & default plugins based on our preference and target platform. By issuing: PharoVMBuilder generate. - it should generate sources - it should generate cmake files, based on environment variable set (btw, can we access an environment variables in our VMs now?) if not, then based on platform that image runs now , which is not good for cross-platform builds, but since now we don't have cross-builds, it will work fine. The approach , again is the same: lets encapsulate the information we need in edible form, not like this one: #!bash -lex # # build-vm.sh -- Builds Cog Virtual Machine. Have to be used together with Jenkins. # # Copyright (c) 2012 Christophe Demarey # export PHARO_VM=`$WORKSPACE/pharo-shell-scripts/fetchLatestVM.sh` if [ -z "$PHARO_VM" ] ; then echo "PHARO_VM environment variable is not set." exit 1 fi # Set environment ============================================================ PROCESS_PLUGIN="UnixOSProcessPlugin" EXTERNAL_PLUGINS="FT2Plugin" ZIP_FILTER='*' if [ "$OS" == "win" ]; then set -e # Stop the execution if a command fails! CONFIGNAME="CogWindowsConfig" PROCESS_PLUGIN="Win32OSProcessPlugin" ZIP_FILTER=' *.exe *.dll' elif [ "$OS" == "mac" ]; then CONFIGNAME="CogCocoaIOSConfig" export MACOSX_DEPLOYMENT_TARGET=10.5 export CC=/usr/bin/gcc-4.2 export CXX=/usr/bin/g++-4.2 else # [ "$OS" == "linux" ]; then CONFIGNAME="CogUnixConfig" export EXTERNAL_PLUGINS="SqueakSSLPlugin $EXTERNAL_PLUGINS" fi # Unpack sources ============================================================= cd "$WORKSPACE" rm -rf cog tar -xzf cog.tar.gz || echo # echo needed for Windows build (error on symlinks creation) mkdir -p cog/build mkdir -p cog/image cd cog/image unzip -o ../../vmmaker-image.zip # Generate sources =========================================================== echo "$CONFIGNAME new addExternalPlugins: #( $EXTERNAL_PLUGINS ); addInternalPlugins: #( $PROCESS_PLUGIN ); generateSources; generate. Smalltalk snapshot: false andQuit: true." > ./script.st "$PHARO_VM" -headless generator.image script.st -headless cd ../../ tar -czf ${CONFIGNAME}-sources.tar.gz -C cog . # Compile ==================================================================== cd cog/build if [ "$OS" == "win" ]; then cmake -G "MSYS Makefiles" . else cmake . fi make if [ "$OS" == "mac" ]; then make install fi cd .. # Install SSL Plugin ========================================================= SSL_PLUGIN_URL='http://squeakssl.googlecode.com/files/SqueakSSL-bin-0.1.5.zip' SSL_PLUGIN_ZIP='SqueakSSL-bin-0.1.5.zip' SSL_PLUGIN_OUT='SqueakSSL-bin' test -e 'SqueakSSL-bin-0.1.5.zip' || \ ($WORKSPACE/download.sh $SSL_PLUGIN_ZIP $SSL_PLUGIN_URL && unzip -o $SSL_PLUGIN_ZIP) if [ "$OS" == "win" ]; then cp $SSL_PLUGIN_OUT/win/* results/ #elif [ "$OS" == "linux" ]; then # cp $SSL_PLUGIN_OUT/unix/so.SqueakSSL results/libSqueakSSL.so fi rm -rf $SSL_PLUGIN_OUT # Archive ==================================================================== cd results COG_ZIP_FILE="Cog-${OS}.zip" zip -r $COG_ZIP_FILE $ZIP_FILTER mv -f $COG_ZIP_FILE ../../ #if [ "$OS" == "mac" ]; then # zip -r ../build/CogVM.zip CogVM.app # mv -f ../build/CogVM.zip ../../ #else # zip -r Cog.zip $ZIP_FILTER # mv Cog.zip ../../ #fi # success exit 0 Another thing, which i discussed locally , i thinking about creating a dedicated blog for VM developers, where we can share the news and describe details about changes and stuff.. In a way, that it will serve as a source of information about VM , jenkins , configurations, settings , building etc etc.. Because all of the bits of knowledge , which we collected till now is kind of floating in the air, and like any energy it tends to dissipate (things we remember and forget, the more things we should keep in head, the faster it happens). Also, blog is preferable to just simple CHANGELOG file (or similar), because it is two-way communication , and people can comment and discuss things. -- Best regards, Igor Stasenko.

[Pharo-project] [ENH]: Test Failure Browser
by Sean P. DeNigris Aug. 1, 2012

Aug. 1, 2012

Issue 6457: [ENH]: Test Failure Browser http://code.google.com/p/pharo/issues/detail?id=6457 This can be included in the Jenkins test images... Browse or debug test failures serialized as fuel files. The Jenkins test script could be enhanced to leave an instance open if there are test failures, so that you would have a dashboard to work from just by downloading and launching the image... Todo: * Toggle button enabling (commented out right now, seems to be a bug in Spec - always passes nil to #whenSelectionChanged: * I want the initial width to be big enough for the contents; it seems like that should be the default. For now, I hardcoded an initialExtent * Layout: how do I specify a toolbar of buttons with static height and that the next row should take up the rest of the height, but not impinge on the toolbar?
