Re: Cog on Linux

Hi Rob, In case you never got a CogVM compiled: I was able to compile to 32bit VM on 64 bit ubuntu 10.04 desktop after installing these packages: lib32asound2-dev libgl1-mesa-dev libglu1-mesa-dev build-essential ia32-libs gcc-multilib g++multilib Then follow the instructions here: http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild/HowToBuild This was the configure incantation: ../../platforms/unix/config/configure CC="gcc -m32" CXX="g++ -m32" CFLAGS="-g -O2 -msse2 -D_GNU_SOURCE -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0" LIBS=-lpthread Then do this: http://forum.world.st/CogVM-td2262856.html#a2262856 But. The VM will open your image, but it seg faults a short, random amount of time after that. Even if you make the change Eliot recommends here: http://forum.world.st/Cog-segfaults-on-linux-td2289607.html#a2289607 Good luck. Paul

Squeak devices and applications
by Torsten Bergmann 22 Jul '10

22 Jul '10

Just read the post from Hilaire about Pharo on OLPC [1]. This leads to the following interesting question: What is the most crazy device Squeak VM is running on? What is the most interesting application where nobody would have expected Squeak/Pharo/Cuis? Feel free to answer by posting screenshots/pictures even if you think the device/app is boring. Would be nice to know and we can collect these to do a little bit of advertising on the Squeak/Pharo web pages... Bye T.

Using FFI on MacOSX
by Nicolas Cellier 22 Jul '10

22 Jul '10

Its not obvious for a Mac newbie like me to get FFI running on MacOSX. What I (re?) discovered is below. Please correct me if I'm wrong. To vm maintainers : wouldn't it be a good idea to pass the flag ffiLoad to ioLoadModule() instead of relying only on a single global variable whether it is a plugin that is requested or not ? This way we could have both secured/fast plugin loading and opened FFI (if distributed in the bundle). Unless there are other reasons unknown of me... Nicolas ----------------------------------------------------- Ah, some news! In order to track and debug the problem with FFI, I built a VM. (uneasy because latest svn xcodeproj is not exactly configured for a one click build...). The problem is that most vm are configured to search for plugin only in squeak bundle (global variable gSqueakPluginsBuiltInOrLocalOnly in files sqMain.c and sqMacUnixExternalPrims.c) I guess this is to save time at startup (and batteries for iPhone...) And also to get some more secure VM (can't load an invalid plugin from an older squeak vm). Unfortunately, no difference is made between loading a squeak plugin and loading a FFI library... There is a ffiLoad flag passed to findAndLoadModule() in sqNamedPrims.c but not to subfunction ioLoadModule() in sqMacUnixExternalPrims.c... (a mistake IMHO) So this setting is preventing FFI to work. What you should do is change this setting: - select your squeak vm in the finder. - Then choose a menu item like "display package content" (it's a guess, my version is configured in french). - Then edit the contents/info.plist with a property editor. - Then uncheck the box corresponding to SqueakPluginsBuiltInOrLocalOnly and save properties Then FFI should be operational again... (But Smallapack may well crash, at least that's what happens here...) I think I will CC squeak-dev/vm-dev to check If I this is the expected solution. Nicolas

Detecting objects that point to an object
by Mariano Martinez Peck 22 Jul '10

22 Jul '10

Hi folks. I need to know the objects (actually, only how many) that are pointing to any object. So...I take an object X, and I want to know how many objects are pointing to X. The only possible I see in Squeak VM is to do a full mark over all objects in memory (or starting by the roots). This is time consuming and I even need (maybe) to do this check (to know how many objects are pointing to an object) for every single object. So...is there a faster solution for this? The only thing I can imagine is to modify the object header, maybe create a new type, and add an array with the addresses of the objects that are pointing to that object. Or maybe just a counter that I can increase or decrease ? Thanks for any tip. Mariano

The current VMMaker for SqueakVM does not use or support pragmas (method annotations). Converting to pragmas makes VMMaker unloadable in older Squeak images. It should be feasible to have the Cog VMMaker handle message send declarations (although I have not tried), but the reverse may not be supportable. If that is the case, then plugins that are intended for use on both SqueakVM and Cog would need to use message-based declarations, at least until such time as we decide to move SqueakVM to use method annotations. Follow-up discussion concerning method annotations in SqueakVM and Cog VMMaker is probably best moved to the vm-dev list. Dave

Re: [Vm-dev] Re: Cog segmentation fault on Linux
by Rob Withers 21 Jul '10

21 Jul '10

Hi Eliot, (I forgot to CC the mailing list - added) I made a few things happen. First, I found that the argument to -leakcheck is an integer that gets masked to determine whether to leak check an incremental or full GC. I made the call with '-leakcheck 7'. Second, I added a -leakcheck section to the COGVM section: #if COGVM else if (!strcmp(argv[0], "-leakcheck")) { extern sqInt checkForLeaks; checkForLeaks = atoi(argv[1]); return 2; } I compiled and ran it. I am unsure where any output from the leak checker goes. If it is to stdout or stderr, I forget the magic incantation to redirect these to files. I think it is '2> stderr.txt 1> stdout.txt' for /bin/sh. Is that right? So when I ran it, it runs (the new image with stepping button bar - takes 30% cpu). When I send 'kill -USR1 <pid>' it seg faults guaranteed. This may or may not be the original seg fault - it may be the leakchecker? The only stuff I am doing that calls out of the image is socket stuff. This may or may not be in the middle of a call when it seg faults. I will work to turn off all the socket activity and see if it still seg faults. Am I activating the leakchecker ok? Regards, Rob From: Rob Withers Sent: Monday, July 19, 2010 9:22 PM To: Eliot Miranda Subject: Re: [Vm-dev] Re: Cog segmentation fault on Linux hey Eliot, It looks like this command line argument, -leakcheck, is for the STACKVM, not the COGVM.

It turns out that this morning I found that I had a button bar that was stepping and part of the step was a Smalltalk garbageCollect to force collection before checking for instances. It may be something I don't need to do anymore, however it helps expose this seg fault. Both stack dumps were in the garbageCollect. I removed the button bar, uploaded the image, and ran it. CPU% dropped from 33% to 2%. I let it run all day. At some point it exited, for an unknown reason, as it was gone when I returned tonight. I have reinstated the button bar, to help this bug occur, and uploaded it to the server. Now I just need to enable -leakcheck. From sqUnixMain.c it looks like it takes an argument. What is that argument?

Here is the stack dump. Below is a second stack dump that looks different. While the heap corruption might be a bug in Cog it might also be heap corruption from external code (e.g. objects passed through FFI calls to external code that overwrites those objects' bounds). There's a leak checker in Cog (see the -leakcheck argument in platforms/unix/vm/sqUnixMain.c) that can help you localise this. Its best to distrust your code before you distrust the VM, simply because thinking it's the VM can blind-side you to potential bugs in your own code or other parts of the system. The goal here is a reproducible case. If you get a reproducible case that doesn't use any external code then the bug is in the VM.
