strange warning in threaded VM/Win

Igor Stasenko
 
i just built a threaded cog VM for win32,
and when i starting an image, a console window shows warnings:
# Debug console
# To close: F2 -> 'debug options' -> 'show output console'
# To disable: F2 -> 'debug options' -> 'show console on errors'
warning, processHasThreadId flag is unset; cannot function as a
threaded VM if so.
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread
warning: Process doesn't have threadId; VM will not thread


however, in pharo we already introduced the threadId ivar:

Link subclass: #Process
        instanceVariableNames: 'suspendedContext priority myList threadId
errorHandler name env'
        classVariableNames: ''
        poolDictionaries: ''
        category: 'Kernel-Processes'

could it be because of initial "warning, processHasThreadId flag is
unset; cannot function as a threaded VM if so."?

Yes. The VM doesn't actually look at class Process - it only checks the
flag in the image header.

The warning is entirely correct, it tells you that the
processHasThreadId ->FLAG<- isn't set.

warning: Process doesn't have threadId; VM will not thread

wheere you see any mention about flag?
i think that it is clear to everyone who reading the above that it is
not about flag, but
about mising thread id var in Process.

i think that it is clear to everyone who reading the above that it is
not about flag, but
about mising thread id var in Process.

Whatever.  The VM doesn't know how to interrogate the class Process to find if it has the inst var.  You tell the VM that Process has the inst var by setting the flag and saving the image.  You set the flag using bit 0 of VM parameter 48.  Find a nice accessor attached.

I know that. Just don't want a confusion to spread.
For me, those warnings are not an issue. But if others start using
that VM they will see that warning, which will lead to same silly
questions by everyone.

Actually, i'd rather turn these messages into notifications, not
warnings. Because there are certain gap between things most people can
ignore, and things
that make them scared " oh my. it wanrs me about something that i
don't understand.. it seems that my image/VM is broken, lets report
that to mailing list..."

OK, so how about
    warning: VM parameter 48 indicates Process doesn't have threadId; VM will not thread 
?
