Re: [Pharo-project] Updated ConfigurationsOf...scripts?

by HernÃ¡n Morales Durand

Ok if there are not, I think is a must, I spend a lot of time searching for the updated scripts or exporting/importing them in my images. What about creating a wiki page in the google project?

Comment #1 on issue 3534 by Torsten....(a)astares.de: LargePositiveInteger(Object)>>error http://code.google.com/p/pharo/issues/detail?id=3534 The problem with this bug is that I was hit by it 7 or 8 times since using the Cog VM. Anytime when opening the world menu. Unfortunately it is hard to reproduce manually, I can open the world menu afterwards without any problem. The problem I see in the debugger is that instead of returning a Color instance (which would understand #pixelValueForDepth:) a large positive integer 4278190081 is returned from the expression "(colors at: i)" in the method ColorForm>>colormapIfNeededForDepth:

Comment #4 on issue 3533 by siguctua: add Dictionary>>at:ifAbsentValue: http://code.google.com/p/pharo/issues/detail?id=3533 Of course, you can always use: dict at: x ifAbsent: y except that it is not always desirable to send #value message to 'y' argument, especially if you can't tell anything about nature of objects you are storing in dictionary, and when speed is essential, it would be good to have something like this: at: key ifAbsentValue: defaultValue "Answer the value associated with the key or, if key isn't found, answer the default value" ^((array at: (self findElementOrNil: key)) ifNil: [ ^ defaultValue ]) value Cog VM shows a significant difference in delivering an answer: | dict | dict := Dictionary new. dict at: #a put: 1. [ 1000000 timesRepeat: [ dict at: #foo ifAbsentValue: #bar ] ] timeToRun 236 234 239 [ 1000000 timesRepeat: [ dict at: #a ifAbsentValue: #bar ] ] timeToRun 241 234 236 237 [ 1000000 timesRepeat: [ dict at: #foo ifAbsent: [#bar] ] ] timeToRun 322 318 [ 1000000 timesRepeat: [ dict at: #a ifAbsent: [ #bar ] ] ] timeToRun 363 336 340

Re: [Pharo-project] DuplicatedVariableError: styler is already defined in PluggableTextMorph

There is a fix already submitted to PharoTaskForces. If you download the last version from the metacello config, it should load well :). Cheers!

[Pharo-project] Dirty MC Packages in Pharo-1.1.1-OneClickCogVM

by Sven Van Caekenberghe

Yesterday I downloaded Pharo-1.1.1-OneClickCogVM from https://gforge.inria.fr/frs/download.php/27524/Pharo-1.1.1-OneClickCogVM.zip and I noticed it has two dirty MC packages (MethodWrappers and Tests). This is probably a glitch, but not nice and confusion for beginners. Sven

[Pharo-project] DuplicatedVariableError: styler is already defined in PluggableTextMorph

When trying to do: Gofer new renggli: 'omnibrowser'; package: 'OmniBrowser'; package: 'OB-Standard'; package: 'OB-Morphic'; package: 'OB-Shout'; package: 'OB-Refactory'; package: 'OB-Regex'; package: 'OB-SUnitIntegration'; load (Part of the build scripts of LR's builder scripting package) I get the following error: DuplicatedVariableError: styler is already defined in PluggableTextMorph while loading the definitiion of OBPluggableTextMorphWithShout in PharoCore 1.2 #12294. I have seen some things flying around on the mailinglist related indirectly to this issue. Is there a solution ? Thx, Sven

TestResource is what you look for.

Re: [Pharo-project] Socket question (Was Re: Xtreams up to date)

by Schwab,Wilhelm K

Attached is some code I wrote a while ago based on advice that ConnectionQueue and SocketStream are correct starting points. I am a big believer that network code should do what it is told until it told to stop; timeouts should be in the hands of the user, application programmer or server administrator, not decided by the socket layer. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of mkobetic(a)gmail.com [mkobetic(a)gmail.com] Sent: Wednesday, January 12, 2011 1:13 PM To: pharo-project(a)lists.gforge.inria.fr Subject: [Pharo-project] Socket question (Was Re: Xtreams up to date) I started looking at the Socket failures that I can reproduce and I can't wrap my head around the SocketReadingWritingTest>>setUp. Based on what I know about TCP sockets it doesn't make sense to me. AFAIK to get both ends of a connected TCP connection (lacking a socketpair call) I need 3 sockets. A listening socket, a client socket (doing connect) and finally the server socket that comes out as a result of accept on the listener. So I'd expect to see something like this in the setUp: | data input output listener socket1 socket2 process sync | Socket initializeNetwork. sync := Semaphore new. listener := Socket newTCP. listener listenOn: 9999. process := [ [ socket1 := listener accept ] ensure: [ listener close ]. sync signal ] fork. socket2 := Socket newTCP. socket2 connectTo: (NetNameResolver localHostAddress) port: 9999. sync wait. output := socket1 reading. input := socket2 writing. Surprisingly, the above doesn't work, while many of the Socket tests seem to pass for me despite my brain telling me that it can't possibly. Can anyone shed some light on this for me ? Thanks, Martin
