cog-based image crashes on mac
Locked
 
|
Hi,
I have been using the Cog VM exclusively for several months now, and from time to time it crashes on me without leaving any trace in debug log. One frequent cause for the crash that I noticed is dealing with Monticello (both reading and writing). Does anyone experience similar things? Am I doing something wrong? The image I got is based on the sources from 27.06.2010. Perhaps a more general idea: given that this VM brings an important improvement, do we want to have a more concerted effort to beta-test it?

Do you ordinarily get output in the log? I have found the Linux vm to be very stingy with such information, but something like
( /fullPathTo/squeakvm \ /anotherFullPath/Pharo-1.0.image # ) 1>pharo_out.txt 2>pharo_error.txt seemed to work. ________________________________________ From: [hidden email] [[hidden email]] On Behalf Of Tudor Girba [[hidden email]] Sent: Sunday, July 25, 2010 6:47 AM To: Pharo Development Subject: [Pharo-project] cog-based image crashes on mac Hi, I have been using the Cog VM exclusively for several months now, and from time to time it crashes on me without leaving any trace in debug log.

No. I directly got the sources from SVN and compile them for Mac.

There's an update in svn that could fix crashes. I had some logging code that looks like
static unsigned long long useclog[LOGSIZE]; static int ulogidx = (unsigned int)-1; # define logusecs(usecs) do { sqLowLevelMFence(); \
if (logClock) useclog[++ulogidx % LOGSIZE] = (usecs); \ } while (0) which blows up when ulogidx wraps around. It the sign of -ve % +ve is undefined in C.
The fix is simple; make the index unsigned: static unsigned long long useclog[LOGSIZE]; static unsigned int ulogidx = (unsigned int)-1; # define logusecs(usecs) do { sqLowLevelMFence(); \
if (logClock) useclog[++ulogidx % LOGSIZE] = (usecs); \ } while (0) HTH Eliot On Mon, Jul 26, 2010 at 4:32 AM, Lukas Renggli <[hidden email]> wrote:

I have a similar problem, with the latest svn version, 2249.
(localPrimIndex > 255) && (localPrimIndex < 520) 15376 squeak: could not load plugin `SocketPlugin' [Switching to process 26735] nanosleep: Invalid argument But it is not random. It happens everytime I try to run PharoCore 12069 tests.

could you have a look at http://code.google.com/p/pharo/issues/detail?id=2579 because henrik mentioned that we missed something or could do it better.

The changes I submitted are the ones of Eliot adapted to work in
Pharo. I don't understand what Henrik writes, if he has something better he should attach the change.

If I'm not mistaken, if primitive 38 fails in Cog, so will primitive 60. Primitive 38 will always fail in a non-cog vm. The failure handling code after the ec == nil check is the same in Float>>basicAt: and Object basicAt: Thus, writing Float>>basicAt: index <primitive:38> ^super basicAt: index would yield the exact same result, with the difference that you will have an extra primtive 60 failure in Cog vm's, an ec = nil check less in non-cog VM's, and no duplication of the fallback-handling code. The alternate code was attached, in issue 2581.
