[Pharo-dev] different execution result debugger vs. 'normal run'
Hi there, In the process of porting our work to Pharo3, I encounter a bug where the execution in the debugger works correctly but not outside of it. It consistently occurs in a testcase of our code, across different images running Pharo 30700 and latest stable vm om mac (26 dec) as well as an older vm (6 sep). Since it's difficult to create a separate public test for this to recreate the problem, how do we go about this? cheers, Johan

Re: [Pharo-dev] Pharo on a Raspbian
you need to subclass NewObjectMemory to override growObjectMemory: delta (see it in NBCoObjectMemory) to enable object memory to be executable you need to subclass from StackInterpreter to override initStackPagesAndInterpret to enable object memory to be executable and to use new object memory class. basically, same sort of changes what i did for NBCoInterpreter, when adapting NB plugin for Cog.

Re: [Pharo-dev] Pharo on a Raspbian
JB? Soon in the blog close to you :) Hi, We compile the StackVM now for RaspberryPi based on a Raspbian os. In order to do that you have to: - get your image - prepare your RaspberryPi or your cross compile environment - and compile First step, the VMMaker image: Here is the link to the source (basically the job just prepare the source and a image): https://ci.inria.fr/pharo-contribution/view/RaspberryPi/job/RaspberryPi-Cog-Git-Tracker/ You will found a preconfigured image in the image folder. If you want to create your own and not just extend this one, you need to clone the pharo-vm git repository: https://github.com/pharo-project/pharo-vm all the used source code is in mc use the filetree in montecello. Second Step Preparing the Raspberry: I used the linux source (raspbian), Then you can recompile using a RaspberryPi (what I do), but you need to follow Nick instruction for install all the required dependencies on the RaspberryPi: On the raspberry PI: # install build tools sudo apt-get install gcc g++ cmake # dependencies for vm plugins sudo apt-get install libasound2-dev libssl-dev libfreetype6-dev libgl1-mesa-dev sudo apt-get install build-essential # to fix: # /usr/bin/ld: cannot find -lSM #/usr/bin/ld: cannot find -lICE # create the following links in: /usr/lib/arm-linux-gnueabihf/ sudo ln -s libSM.so.6 libSM.so sudo ln -s libICE.so.6 libICE.so Once the source is installed: chmod +x platforms/unix/config/version chmod +x platforms/unix/config/verstamp Then compile: I have done a configuration to generate VM on raspbian. StackRaspbianConfig, you need to subclass and add your plugin + configure Cmake as you want. YourSubclass generate and recompile (cmake . make from a terminal in build folder) on the Raspberry Pi, it should work. My jenkins job actually take the last version of the source VM, and it is able to rebuild it on RaspPi. You can cross-compile but I do not explore that way. I hope that help you. Second mail I will explain everything. First of all the StackVM on rbp now work only on headless mode but soon the fast bltbit will be introduce. The main issue is you cannot develop directly on raspberryPi for now. You need to develop on another os for prepare the environment and then push it on your raspberryPi for compile (I have a job jenkins to do that). You need to do newImage.sh, but this will not work on raspberry pi. For create your generator image. In this image load you own source. (with your configuration and plugin). You can use this image to generate vm, try to do not keep this image for keeping your vm up to date. after that you need to: - first generate source in by doing: YourConfigSubclass new generateSources.. but this step is really long If you do on raspberry pi, but you can do on raspberry pi, you can also do this step before send the source on the Rasp (what i do to save time). - second you need to generate CMakeFile. That step should be perform on RaspPi The process required a working vm, Here is a working vm for RaspberryPi on Raspbian: https://ci.inria.fr/pharo-contribution/view/RaspberryPi/job/RaspberryPi-Compilation/ As you cannot run the VM with UI So, you need to run a script.st like this one. echo YourConfigSubclass new generate. Smalltalk snapshot: false andQuit: true. ./script.st execute like that in a shell: ./StackVM -vm-display-null generator.image script.st - third step: build. in build folder do: sh build.sh RaspberryPi is slow for recompiling everything. Maybe a solution for develop faster is to cross-compile but as I say I do not explore that way.

Re: [Pharo-dev] ScreencastMorph
Sean did you try to create a new WorldMorph? Now one of the problem is that there is only one hand (global variable). In Bloc alain removed the ActiveHand and ActiveWorld globals. Stef On 16 Jan 2014, at 15:53, DeNigris Sean s...@clipperadams.com wrote: I'm working on a ScreencastMorph. The idea is to have something like what HandMorphForReplay does, but in a self contained window. The effect would be that there was another World running in a window, where the HandMorphForReplay could carry out a UI script that could be played, sped up, slowed down, rewound - all the actions you would except from a media player. Unfortunately, starting a World in a window does not seem easy. Most of the time I try it or manually mess with HandMorphs, my image locks up permanently. I've also had trouble getting the tool to resize. I tried Window - TransformationMorph - PasteUpMorph - MyCoolToolWindow. That seems promising - although I have to open the tool in the world before embedding in the PasteUpMorph. The tool will resize and even interact for a while, but eventually that too seems to lock up the image. Any ideas? Thanks, Sean p.s. cross-posting to Squeak-dev and Pharo-dev. If I get it working, I plan on porting to both. p.p.s. I'm posting to the dev lists because I see clear killer uses for this in the Core system (UI Testing, live documentation)
Re: [Pharo-dev] Displaying labels with Athens on Linux?
For normal humans you do not convey the pain behind …. here is the answer I got from the two amigos igor and ronie that looked at the problem We debugged in both machines at the same time. Installed some debug symbols, looking at the libpixman source code. Disassembling and looking some instructions. When I saw the use of intrinsics in the source code, I started to suspect a bit of the alignment of some stuff and when Igor, found the segmentation fault causing instruction movdqa (Move double-quadword aligned), it was clear that it was a stack alignment issue. Checking the Intel manual confirmed this and I asked about whose responsible for aligning the stack, suspecting it was a problem with the library not conforming to the ABI. Then, Igor remembered how to change the stack alignment in native boost and it worked. This is why having people with such knowledge around is key to let us (the smart cosy smalltalkers) having fun with our cool language. Stef Fix integrated. in 3.0 704 -- Best regards, Igor Stasenko.

With this now PUnQLite package can be loaded again in Pharo 3.0 without errors: Gofer new url: 'http://smalltalkhub.com/mc/MasashiUmezawa/PunQLite/main'; package: 'ConfigurationOfPunQLite'; load. (Smalltalk at: #ConfigurationOfPunQLite) load The examples from https://github.com/mumez/PunQLite work, EXCEPT one: Import from files db := PqDatabase open: 'mczCache.db'. (FileSystem workingDirectory / 'package-cache') files do: [:each | (db importAt: each basename fromFile: each pathString) ifTrue: [db commitTransaction]. ]. db keys inspect. db close. which first gives an PqCursor error and when run for a second time leads to a hard VM CRASH (on Windows 8). Anyone able to reproduce? Note that one requires UnQLite library to reproduce which is prebuilt here: https://github.com/mumez/PunQLite/tree/master/binary I guess it is somewhere in #importAt:fromFile: which uses memory mapped files...

Thanks! Still there is a problem: (NBExternalTypeValue ofType: 'NBInt64'). in a Pharo3.0 Latest update: #30703 (with the fix integrated) throws now an #DNU because the new anonymous subclass of NBExternalTypeValue class does not understand #rebuildFieldAccessors NBExternalTypeValue(class)valueType: sends #rebuildFieldAccessors but there is no such method in this hierarchy. But there is NBExternalStructurerebuildFieldAccessors and NBExternalTypeValue(class)installAccessors.

Re: [Pharo-dev] Displaying labels with Athens on Linux?
I suspected a big pain, but not that much. Thanks guys!

Installed some debug symbols, looking at the libpixman source code. Disassembling and looking some instructions. When I saw the use of intrinsics in the source code, I started to suspect a bit of the alignment of some stuff and when Igor, found the segmentation fault causing instruction movdqa (Move double-quadword aligned), it was clear that it was a stack alignment issue. Checking the Intel manual confirmed this and I asked about whose responsible for aligning the stack, suspecting it was a problem with the library not conforming to the ABI. Then, Igor remembered how to change the stack alignment in native boost and it worked. This is why having people with such knowledge around is key to let us (the smart cosy smalltalkers) having fun with our cool language.

Re: [Pharo-dev] Pharo on a Raspbian
Btw, to reduce the pain, i propose to introduce: NativeBoost isAvailable protocol. The implementation is simple, since primitiveIsEnabled fails only if it not exists (else it returns true or false), do a following: isAvailable ^ self primIsAvailable notNil primIsAvailable Answer flag indicating whether running a native code enabled by plugin primitive: #primitiveIsEnabled module: #NativeBoostPlugin ^ nil Then you can easily implement a fallback mechanisms, if NB is not avail.

Re: [Pharo-dev] different execution result debugger vs. 'normal run'
I figured it out and it's because of this: DateAndTime now = DateAndTime now is true in Pharo 3 is false in Pharo 2.0 is false in Pharo 1.4 Did Pharo3 become so fast or did the clock precision decrease?

Re: [Pharo-dev] different execution result debugger vs. 'normal run'
And I will answer my own question, having found the thread on the subject [1]. short answer: DateAndTime now got faster ;-) Good job guys! Our test was flawed because it relied (unknowingly) on the delay in DateAndTime creation. thx!
