squeak-dev@lists.squeakfoundation.org, seaside@lists.squeakfoundation.org, pharo-project@lists.gforge.inria.frSurvey for framework and library developers: "Information needs in software ecosystems"
by Nicole Haenni 03 Mar '13

03 Mar '13

Hi, I’m Nicole Haenni and I'm doing research for my thesis at the University of Berne (scg.unibe.ch) with Mircea Lungu and Niko Schwarz. We are researching on monitoring the activity in software ecosystems. A software ecosystem might be a project repository like GitHub, an open source community (e.g. the Apache community) or a language-based community (e.g. Smalltalk has Squeaksource, Ruby has Rubyforge). This is a study about information needs that arise in such software ecosystems. I need your help to fill out the survey below. It takes about 10 minutes to complete it. We formulate our research question as follows: "What information needs arise when developers use code from other projects, or see their own code used elsewhere." Survey link: https://docs.google.com/spreadsheet/viewform?formkey=dFBJUmVodVU1V3BMMGRPRW… Thank you for your support!

EventSensor>processEvent: has bogus code
by tim Rowledge 03 Mar '13

03 Mar '13

I'm trawling around in the bowels of Scratch and spotted some ugly soreta-event code. I've checked a nice recent image and although the ugly is different it still seems to be there in spirit at least. Same basic code is in Cuis as well - EventSensor>processSensorEvent: For a while now - about a decade I'd think - the VMs have *not* reported the use of the set interrupt key (which is *still* set to cmd-. Mac style and not to a platform suited value except on RISC OS) as a keyboard event. Thus the clause in EventSensor>processEvent: where " type = EventTypeKeyboard ifTrue: [ "Check if the event is a user interrupt" ((evt at: 4) = 0 and: [((evt at: 3) bitOr: (((evt at: 5) bitAnd: 8) bitShift: 8)) = interruptKey]) ifTrue: ["interrupt key is meta - not reported as event" ^ interruptSemaphore signal]. " does the testing is bogus. It even has a comment explaining why it is bogus. Unless I'm missing things (it's Friday afternoon ok?) this clause really ought to be removed. And really - we still have all those long obsolete io prims called in there too? Oh my. You can just about excuse the VMs having the code to support ancient images, but not modern images. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Fractured Idiom:- RIGOR MORRIS - The cat is dead

Re: [squeak-dev] The Trunk: Network-fbs.140.mcz
by David T. Lewis 02 Mar '13

02 Mar '13

I am not sure how to reproduce the original problem (on Linux), but I'm not sure if the proposed fix will work if the IPv6 networking is disabled in preferences. The resolver behaves differently depending on whether the new network primitives are being used, and may answer #[0 0 0 0] rather than nil. NetNameResolver useOldNetwork: true. NetNameResolver addressForName: 'foo' timeout: 20 ==> #[0 0 0 0] NetNameResolver useOldNetwork: false. NetNameResolver addressForName: 'foo' timeout: 20 ==> nil Dave On Fri, Mar 01, 2013 at 10:39:44AM +0000, commits(a)source.squeak.org wrote: > Frank Shearar uploaded a new version of Network to project The Trunk: > http://source.squeak.org/trunk/Network-fbs.140.mcz > > ==================== Summary ==================== > > Name: Network-fbs.140 > Author: fbs > Time: 1 March 2013, 10:39:25.076 am > UUID: 9f6d4989-84fc-4303-87ab-406d2296fd73 > Ancestors: Network-fbs.139 > > If the user gives up on trying to resolve a name, fail the socket connect completely. > > http://bugs.squeak.org/view.php?id=4025. > > =============== Diff against Network-fbs.139 =============== > > Item was changed: > ----- Method: SocketStream class>>openConnectionToHostNamed:port: (in category 'instance creation') ----- > openConnectionToHostNamed: hostName port: portNumber > | hostIP | > hostIP := NetNameResolver addressForName: hostName timeout: 20. > + hostIP ifNil: [NetworkError signal: ('Cannot resolve {1}.' format: {hostName})]. > ^self openConnectionToHost: hostIP port: portNumber!

Block argument syntax
by Frank Shearar 02 Mar '13

02 Mar '13

I was rather surprised to learn that the following is valid syntax: [ : x | x + 1] (Note the space before the argument name.) In fact, this is too: [ : "This is a really long comment in a very, very strange place. It makes it very hard to see that the : before this comment turns the token after this comment into a block argument." x | x + 1] Is that intentional? Does ANSI Smalltalk define it? frank
