Bug in #requiredSelectors?
by Zulq Alam 25 Jul '08

25 Jul '08

Is this a bug or am I doing something wrong? The last assertion fails, i.e. #requiredSelectors does not reflect removal if interest has been declared. " Declare interest in String. " RequiredSelectors current noteInterestOf: DynamicProtocols in: String. " Prove that the method we're adding isn't already present. " self assert: (String requiredSelectors includes: #requiredMethod) not. " Add a method the implies a new required method. " String compile: 'implyRequired self requiredMethod'. " Prove that the implied required method is known. " self assert: (String requiredSelectors includes: #requiredMethod). " Remove the method. " String removeSelector: #implyRequired. " Prove that the required method is no longer implied. " self assert: (String requiredSelectors includes: #requiredMethod) not. " Lose interest. " RequiredSelectors current lostInterest: DynamicProtocols in: String. It seems like the cache is not being updated. Thanks, Zulq.

About on:do:
by stephane ducasse 25 Jul '08

25 Jul '08

Hello I would like to know how the VM defines on:do: on: exception do: handlerAction "Evaluate the receiver in the scope of an exception handler." | handlerActive | <primitive: 199> "just a marker, fail and execute the following" handlerActive _ true. ^ self value I'm on a rather non existent internet connexion and I do not have the vm code and I would like to know where how the exception and handlerAction block are stored. I was imagining that may be the vm stores them in the previous context. Stef

Exception return: 10 vs 10
by stephane ducasse 25 Jul '08

25 Jul '08

Hello I'm trying to understand the exact difference between using return: and not as a last statement of a on:do: block I read the excellent tests of ExceptionTester (Tx andreas they are cool). returning "self new returning" ^ [self firstActionSignalingAnError. self secondActionReturning42] on: Error do: [:ex | Transcript show: 'An error has occurred: ', ex messageText ; cr. ex return: 69] returning "self new returning" ^ [self firstActionSignalingAnError. self secondActionReturning42] on: Error do: [:ex | Transcript show: 'An error has occurred: ', ex messageText ; cr. 69]

About ClassBuilderChangeClassTypeTest
by stephane ducasse 25 Jul '08

25 Jul '08

Hello guys I only find two methods (and not tests) in ClassBuilderChangeClassTypeTest and I was wondering if such tests exist somewhere. I plan to write tests for classBuilder and I would like to avoid reinventing the wheel. Thanks. Stef

by Jerome Peace 25 Jul '08

25 Jul '08

Hi all, Q: Why are TTCFont Glyphs forms of depth 32? As a bug tracker I've been looking into a whole slew of font code. It is sprawling and confusing (to me). I can't easily figure if what I am looking at is legit or not. So first an easy queastion. Can anybody help with an answer? Yours in curiosity and service, --Jerome Peace

RFB Mantainer
by Esteban Lorenzano 24 Jul '08

24 Jul '08

Hi all, Is the RFB mantainer around? I want to add a "keepRunning" flag to RFBServer, to keep the server when I restart the image (this is useful for headless images -running seaside). Of course, I can keep my own version of RFB, but I think is better to have just one and expand the options of use. Cheers, Esteban

Can I sneak in a Monticello save into this running image?
by itsme213 24 Jul '08

24 Jul '08

I've got my image in some loop, quite unresponsive (XP) and 100% CPU. If I try to close the window I get the "quit squeak without saving" dialog, and (presumably due to some UI thread blocking on the dialog) CPU drops to 0. In this state is there any way to sneak in a Monticello save of my working package? Thanks! Sophie

Content for the new web site (was: http://www.pragprog.com/screencasts)
by cdrick 24 Jul '08

24 Jul '08

Just 2 remarks for the future web site: > http://live.eclipse.org/ That'd be good to have an equivalent in the new squeak.ork site ;). Also, I think embedding nabble squeak page could be nice (butI think we need the owner to access the javascript snippet to insert) http://www.nabble.com/Squeak-f14152.html Cédrick

new blog post plus closure bootstrap code
by Eliot Miranda 23 Jul '08

23 Jul '08

Hi All, I've made a significant step today in making available the first cut of my closure scheme. There is a new blog post on www.mirandabanda.org/cogblogabout the closure bytecodes which at the end includes a pointer to the bootstrap @ www.mirandabanda.org/files/Cog/Closures0808/Bootstrap/. The bootstrap has been tested on internal Qwaq images, and on Croquet 1.0 and Squeak 3.9. I'd love to hear of other ports, e.g. to 3.10 and to Spoon. I'm interested in bug reports (I haven't yet tested eToys) and code reviews and tying up loose ends (for example I broke decompile with temp names and haven't fixed it). Thanks and enjoy.
