OSCog updated

Hi All,

I've updated http://ftp.squeak.org/Cog with new source, OpenSourceCog-oscog.16.tar.gz/VMMaker-oscog.16.mcz that fixes the three issues people have found:

Nicholas' crash on loading SUnit.dtl.?? which was a very nasty bug in the GC'ing of some trace logs the VM maintains. It was down to a difference between Smalltalk's \\ and C's %, specifically that the latter can answer something of different sign to the modulus.

The failure of GeneratorTest, superficially due to cannotReturn: crashes, but fundamentally to do with inter-page returns to frames within the page not preserving the frames above, which can be in use due to co-routining (swapSender: usage). I hope this will fix Seaside on Cog. Please let me know.

Crashes due to temps occurring in very simple blocks (that Cog compiles frameless) e.g. [ | b | 5 ] value.

HTH

Eliot

Thank you for the update, unfortunately the update does not seem to
fix the problem with Seaside.

I've ripped out the failing functionality and the associated tests.
You should be able to load Seaside-Pharo-Continuation and
Seaside-Tests-Pharo-Continuation into any recent Pharo or Squeak image
to reproduce the problem. On traditional VMs all 16 tests pass.

Hi Lukas,

this is now fixed in r2221 of http://www.squeakvm.org/svn/squeak/branches/Cog & www.squeaksource.com/VMMaker/VMMaker-oscog.17.

Re: [squeak-dev] OSCog updated

Hi Eliot,

Thank you for the quick fix. I can confirm that all 1600 Seaside 3.0
tests run green now.

However I stil get random crashes when using Seaside through the
webbrowser. Sometimes it survives 30 requests, sometimes it crashes
right after the first request. In the console I get:

nanosleep: Invalid argument
Exited with exit code: 1

How can I further debug this? I cannot reproduce it with the tests. It
only happens (randomly) when using Seaside through the webbrowser.

Maybe this is network related issue?
