Re: [Vm-dev] Fwd: Compiling Squeak failed with VMMaker on Mac
by John M McIntosh 19 Apr '07

Ok, I checked in a UnixOSProcessPlugin folder in the Mac OS plugins tree that contains the xcode project to build 4.01 someone can take it and build a 4.xx version, and test. Then feedback the source and any changes and I'll build a binary for inclusion as a plugin the 3.8.17b1 version of the mac carbon vm. I've also added a note to the readme about the old browser technology, versus the new browser technology. -- ======================================================================== === John M.

Building gold Mac flavour
by Mathieu Suen 18 Apr '07

18 Apr '07

Hi, I'm reading the readme for mac so at the five six I can't find the Info-NPSqueak__Upgraded_.plist file. Where can I find it? Also when I open XCode the ExuperyPlugin.c file is missing which it's normal because I haven't download the plugin but It's optional so how to avoid a error when you build it? Thanks Mth

[BUG] Mysterious Delay lockups
by Andreas Raab 18 Apr '07

18 Apr '07

Hi Folks - Some of you (mostly those who run heavy servers) may have noticed that at times Squeak locks up in mysterious and unforeseen ways. One of those lockups involves Delay's AccessProtect in an unsignaled state and consequently the entire image locking up since Delay access is required in many, many places. Today, David presented me an image that was locked up in such a state but by sheer luck he managed to save it right before it happened which allowed me to investigate the situation. The result can best be explained by the little test case shown here: "Create mutex unsignaled so we can manually signal it" mutex := Semaphore new. "Create a process which will wait inside the mutex" p := [mutex critical:[]] forkAt: Processor userBackgroundPriority. "Wait until process has entered mutex" [p suspendingList == mutex] whileFalse:[(Delay forMilliseconds: 10) wait]. "Signal mutex" mutex signal. "Kill process" p terminate. "and check to see if the mutex is signaled" mutex isSignaled ifFalse:[self error: 'Mutex not signaled']. Note that despite the somewhat complex setup the basic idea is that a low priority process waiting in a critical section receives a signal on the semaphore it is waiting on but gets terminated by a higher priority process inbetween receiving the signal and execution of the process itself. This situation (manually executed in the above to make it more easily repeatable) can happen in many situations where processes get terminated "from the outside" and it would cause particular grief in the timing semaphore because it gets served by the highest priority process which makes the unfortunate cause of events much more likely. All Squeak versions that I have access to expose this behavior. Looking at Semaphore>>critical: which says Semaphore>>critical: aBlock self wait. [blockValue := aBlock value] ensure: [self signal]. makes it seem as if moving the wait into the ensured block is the correct answer, but that ain't necessarily so. When we move the wait into the block we risk that the entering process is terminated after entering the block but before entering the wait which would leave the semaphore signaled twice, which is just as bad as not signaled at all. Methinks a solution would involve Process>>terminate but I'm running out of steam after trying to understand the problem in all its implications. Any ideas would be greatly welcome. Cheers, - Andreas

Hi, I would like to know which version of the Squeak Image and VMMaker I should use to be able to play with the InterpreterSimulator? Did you plane to port it to squeak 3.9? Thanks Mth

Building Unix 3.9-8 Squeak VM On Intel Mac
by Ken G. Brown 16 Apr '07

16 Apr '07

Working with Craig to get the Spoon stuff working on MacIntel (MacPro 10.4.9). I installed Xcode 2.4.1 to get gdb and compilers but did the following from Terminal: Tried compiling the Unix sources from Squeak-3.9-8.src.tar.gz at <http://squeakvm.org/unix/> according to the HowToBuildFromSource.pdf and incorporated Todd's instructions below, and tried opening Sq-dev-beta-107.image but it hangs with 100% cpu. Have the 3.9 sources. Also tried an older image Squeak3.7a-5905.image and V3 sources with same results. Ideas anyone?

Hi, I had try to build the source of squeak but at the end I have got a /usr/bin/ld: Undefined symbols: _closeWindow _createWindowWidthheightoriginXyattrlength ... I had toke the latest source from svn and the latest VMMaker (3.8b6) with Squeak 3.10 image. Idea? Mth

Unix VM crash on MacOSX
by Craig Latta 13 Apr '07

13 Apr '07

Hi-- On MacOS 10.4.9 (PPC), when I build the Unix VM from the sources at squeakvm.org (3.9-8), and try to run Squeak3.9-final-7067, I get: *** Segmentation fault 53273604 SystemDictionary>lowSpaceWatcher Bus error *** When I run the same image with the pre-built PPC MacOS 3.9-8 VM on squeakvm.org, things are normal. When I run that image on Linux with a VM built from the same sources, things are normal. Any ideas? thanks! -C -- Craig Latta improvisational musical informaticist www.netjam.org Smalltalkers do: [:it | All with: Class, (And love: it)]

Re: Strange InvalidDirectoryErrors on Unix
by Andreas Raab 11 Apr '07

11 Apr '07

Hi - Turns out my analysis was a red herring - the InvalidDirectoryError I received was actually a genuine problem which caused the whole computation to abort before it even reached the updating part. I got confused because I didn't realize that the problem might be caused before it ever gets to the updating part and invoking the updater manually would of course work. Apologies for making a fuzz over nothing. Cheers, - Andreas Andreas Raab wrote: > J J wrote: >> What kind of filesystem is this on?
