ifTrue ifFalse shortcuts
by Peter UhnÃ¡k Aug. 10, 2016

Aug. 10, 2016

Hi, was removal of ifTrue/ifFalse shortcuts on purpose, or by accident? https://pharo.fogbugz.com/f/cases/16125/Nautilus-doesn-t-recognize-the-cmd-… (maybe was caused by switch to Rubric?) Peter

I noticed the SmallPOS on ss3 is under MIT license. AFAIK, it was GPLv3. When did this relicensing happen? Stephan

Problem with delay waiting (OSSubprocess code) on Pharo 5.0
by Mariano Martinez Peck Aug. 8, 2016

Aug. 8, 2016

Hi guys, I am seeing a problem in Pharo 5.0 regarding Delay >> wait. I cannot explain how this could happened but it does, and it happened to me a couple of times (but not fully reproducible). In OSSubprocess I have this child watcher: initializeChildWatcher "This is a process which waits for the death of a child processes. Use SIGCHLD events rather than a Delay to poll." | processSynchronizationDelay | *processSynchronizationDelay := Delay forMilliseconds: 20.* childWatcher ifNil: [ childWatcher := [[ "OSProcess authors suspected that there were various ways in which OS signals could be missed under conditions of heavy load. For that reason, we use #waitTimeoutMSecs: with the semaphore, so that if a signal is missed, we time out and rescan occasionally anyway (#updateActiveChildrenAndNotifyDead sends queryExitStatus which sends waitpid() ) " self sigChldSemaphore waitTimeoutMSecs: 1000. *processSynchronizationDelay wait. "Avoids lost signals in heavy process switching"* self updateActiveChildrenAndNotifyDead. ] repeat] newProcess. childWatcher resume. "name selected to look reasonable in the process browser" childWatcher name: ((ReadStream on: childWatcher hash asString) next: 5) , ': the OSSubprocess child watcher' ] The problem is that now above process is hung on the "*processSynchronizationDelay wait.". *At least that's what I can see from the process browser. That should not hung, of course, and should stop waiting after 20 ms. If I inspect the Delay instance in question (doing the wait) I see that the print string is bad.... "a Delay(20 msecs; 3641032396485 msecs remaining)". WTF? 20ms and you remain 3641032396485 to wait??? I attach an screenshot of the Delay instance in case there could be something wrong. Maybe it is wrong to keep and re-use same instance of Delay? (note it is outside the closure) (this was not a problem in the past). Thanks in advance for any clue. -- Mariano http://marianopeck.wordpress.com

Limbo/PharoInProgress repositories
by Serge Stinckwich July 29, 2016

July 29, 2016

Dear all, on SquareBracketAssociates github org, I see a Limbo repo : https://github.com/SquareBracketAssociates/PharoLimbo and a PharoInProgress repo: https://github.com/SquareBracketAssociates/PharoInProgress Basically there are collections of chapters that are not part of any books until now. And there is also a repo called: PharoReadyForReviews https://github.com/SquareBracketAssociates/PharoReadyForReviews for chapters ready for reviews but with some chapters more than 2 years old. Does it make sense to merge all these repos in one ? Having too much repos, we forget about the others ... BTW, I add a draft of a chapter regarding Continuations (in French) I wrote several years ago : https://github.com/SquareBracketAssociates/PharoLimbo/blob/master/Continuat… Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Option for as-in-moose debugger layout
by Yuriy Tymchuk July 29, 2016

July 29, 2016

Hi, is it possible to have some setting to switch the debugger into the layout that is used in Moose? I.e. have the stack vertically on the left. Because come on, look at this image: only 3 lines of variables? And you see all that empty space on the right both in source code and variables pane? Cheers. Uko
