Hi!
I have a problem in the recent Pharo 4 image: the method MonitorDelay>>#signalLock:afterMSecs:inMonitor:queue: returns a boolean instead of MonitorDelay object. And in the method Monitor>>#exitAndWaitInQueue:maxMilliseconds: it raises message not understood on #unschedule.
Pharo #40505.
-=-=- | monitor | monitor := Monitor new. monitor critical: [ monitor waitWhile: [ true ] maxMilliseconds: 200 ]. -=-=-
Is it known error? Someone is changing Monitor or related code? Thanks, Juraj

Well, basically it is enough to add #yourself in to the class method:
signalLock: aSemaphore afterMSecs: anInteger inMonitor: aMonitor queue: anOrderedCollection anInteger < 0 ifTrue: [self error: 'delay times cannot be negative']. ^ (self new setDelay: anInteger forSemaphore: aSemaphore monitor: aMonitor queue: anOrderedCollection) schedule; *yourself*
But I am wondering if it is the only one affected method. If someone agree with this solution, I can create test case and slice.
Cheers, Juraj

Yes, this has changed (see multiple issues on fogbugz). Ben Coman uses the return value in WorldState>>#interCyclePause: for tesing if the delay has been scheduled.
I think there is a good chance that Monitor is the only class that expects the Delay as the return value. So, yes, please create a fix with your proposed solution. - or wait for Ben to comment on this :)

Juraj, Your solution looks fine. Please go ahead to create a Fogbugz issue and submit a slice. It would be cool if your test covers the usage of that method and not "just" that it returns a particular class, since there seems no existing test for that method. I haven't had a lot to do with Monitors so it would be good to see a use case. If you notify me when you <Resolve> the issue I'll be happy to review. btw, can you cover both methods? Actually, looking through senders of #schedule, Delay class>>timeoutSemaphore:afterMSecs: suffers the same. Juraj could you cover this also? cheers -ben
