[M3devel] Juno/win32threads

[Jay K]

Yes that's what I was referring to.

You were already looking at the right timeframe, around Feb 20 2009.

Earlier mail has a 30 minute window identified.

P.S.  I did commit back some changes to ThreadWin32.m3 which backed out some of 1.30.  Did you try those?

OK, I've lost track, since we've been discussing two different things: the problems with pthreads which I just fixed, and the Windows threading problem.  What is the time-frame that I should be looking at for that problem?

Eh? Tony, the thread changes from around feb 20 that you recently 'unmerged'? These crashes seem to date from around Feb, more precise info in my other mails..

I don't think anything I changed affects Windows.

Tony, the behavior still seems the same.

Can you maybe debug this on birch?
 
I can e.g. put debuggers at \bin\x86\cdb
 (just install them locally which involves some GUI, then tar/gz them up and untar/gz..you don't need the installer to run, can just copy them around)
and then you can like:
 
ssh hudson at birch.elegosoft.com
ssh elego at localhost2
/cygdrive/c/bin/x86/cdb ./Juno.exe
 
Just be sure not to run Juno outside of a debugger..not sure what will happen, but you won't be able to see it.
 
Or, feel free to commit some version that uses RTIO a bunch and I can send you the output.
Slow turnaround that way.
Clearly nobody is using any of this stuff..
