Maybe we can add this to the cleanUpForRelease script. Cheers -- Miguel CobÃ¡ http://miguel.leugim.com.mx

[Pharo-project] Delay startTimerInterruptWatcher in ScriptLoader >> cleanUpMethods -> DNU
by Mariano Martinez Peck March 1, 2010

March 1, 2010

Try to evaluate ScriptLoader new cleanUpMethods and you will see that in ScriptLoader >> cleanUpMethods you do: Delay startTimerInterruptWatcher. and there is the DNU as startTimerInterruptWatcher is never implemented. Solutions ? 1) Remove Delay startTimerInterruptWatcher. from cleanUpMethods 2) Maybe the message should be stopTimerEventLoop ?? I have no idea The only thing I found in the issues was this: http://code.google.com/p/pharo/issues/detail?id=1424 In squeak 3.9 the method is implemented, and like this: startTimerInterruptWatcher "Reset the class variables that keep track of active Delays and re-start the timer interrupt watcher process. Any currently scheduled delays are forgotten." "Delay startTimerInterruptWatcher" | p | self primSignal: nil atMilliseconds: 0. TimingSemaphore == nil ifFalse: [TimingSemaphore terminateProcess]. TimingSemaphore _ Semaphore new. AccessProtect _ Semaphore forMutualExclusion. SuspendedDelays _ SortedCollection sortBlock: [:d1 :d2 | d1 resumptionTime <= d2 resumptionTime]. ActiveDelay _ nil. p _ [self timerInterruptWatcher] newProcess. p priority: Processor timingPriority. p resume.

[Pharo-project] databases

Hi, I would like to learn on Pharo + databases. I've seen there's several solutions in both object and relational databases. - Which (open source) object database should I start with (most used) ? - Which object database can be accessed from Smalltalk AND Ruby or Python ? How ? - I want to try MySQL too. Is there up to date small applications on squeaksource which show this stuff quite well ? Thanks for help ! Laurent Laffont
