Hi Mike,
I'm not sure of this is the final wanted shape for Semaphore>>critical
(From 6755SemaCritical):
critical: mutuallyExcludedBlock
"Evaluate mutuallyExcludedBlock only if the receiver is not currently in
the process of running the critical: message. If the receiver is, evaluate
mutuallyExcludedBlock after the other critical: message is finished."
| blockValue caught |
caught := false.
[
caught := true.
self wait.
blockValue := mutuallyExcludedBlock value
] ensure: [caught ifTrue: [self signal]].
^blockValue
There was a bit of discussion about putting the "caught" flag AFTER the
wait. Something like:
self wait.
caught := true. "signal the flag just after we got the semaphore"
See http://tech.groups.yahoo.com/group/squeak/message/123504 for an
explanation from Andreas.
Cheers,
-- Diego
