[Pharo-project] 'file:spaceTally.st' asUrl retrieveContents should work?
by Mariano Martinez Peck Sept. 21, 2010

Sept. 21, 2010

Hi...I was running a pharo headless in Mac OS running something like this: ./Pharo/VM/Squeak\ 4.2.5beta1U.app/Contents/MacOS/Squeak\ VM\ Opt -headless Pharo/imagenes/Pharo-1.1-11411dev10.07.1/Pharo-1.1-11411dev10.07.1.image spaceTally.st And I come to the problem that there is an error while trying to process spaceTally.st. This file is a text file that just contains "SpaceTally new printSpaceAnalysis" Now....to conclude, the problem is that according to the wonderful and nice CodeLoader (I really hate this class...I promise I will do something with it) this: 'file:spaceTally.st' asUrl retrieveContents should answer me the contents ("SpaceTally new printSpaceAnalysis") ...but instead nil is returned. The file exist. Is this wrong? is it expected? how can I fix it ? Thanks!! Mariano

[Pharo-project] running Magma tests in 1.1
by Chris Muller Sept. 21, 2010

Sept. 21, 2010

To run the test-suite for Magma 1.1r2 in Pharo: - Proceed past two warnings about "FlapTab" when loading Magma. - Revert FileDirectory>>#fileExists: to the prior version. - Remove #testClassSchemaUpgrades. - Load OSProcess. The second and third steps, above, I believe may be regressions in Pharo 1.1. In Pharo 1.1: FileDirectory default fileExists: '/bin/sh' "---> false" but the file does, indeed, exist as a soft-link. Squeak answers true and, I'll bet, so does Pharo 1.0, so I'm not sure if there is a problem here or not. #testClassSchemaUpgrades tests Magma's ability to keep up with class-schema changes in the image. Usually class-schemas change only in development, not production systems so maybe it's not a big deal. But still, it can be very convenient develop new class schemas while connected to a persistent Magma store. Magma makes use of the SystemChangeNotifier to do this. I don't know if Pharo cleaned something with SystemChangeNotifier or a regression happened, but I don't have time to debug it right now. Certainly, if there is a problem with Magma I will fix it, but I'm not convinced of that yet. - Chris

[Pharo-project] ThemeSettings>>#menuSelectionColor: should return self
by Sven Van Caekenberghe Sept. 20, 2010

Sept. 20, 2010

I was playing with the new Pro theme, and this bit me hard (crashed my image several times before I found out why): ThemeSettings>>#menuSelectionColor: should return self not a Color, just like all other setters, otherwise the cascades in UITheme class>>#newDefaultSettings won't work, although a final #yourself would be good style there too.

[Pharo-project] Experimental Cocoa OS-X based Squeak Cog JIT VM 5.8b3.
by John M McIntosh Sept. 20, 2010

Sept. 20, 2010

I've stuck a version (5.8b3) of the cocoa based os-x squeak cog JIT based VM in my experimental folder. http://homepage.mac.com/johnmci/.Public/experimental/Squeak%205.8b3.app.zip This VM is built from the Cog sources (with some minor changes for the iPhone) & revised & fixed Socket Plugin. It currently does NOT contain any external plugins. I did check in the changes to squeakvm.org that are required to build this VM excluding the required Cog changes... People are invited to take it for a whirl, report any performance gains, issues and especially crashes. PS (a) yes shortly we'll get the iPhone changes folded back into the source tree so you can build the VM. (b) yes when resizing a window you get neat graphic effects (fixing that issue is non-trival). (c) As time permits we'll look into rebuild this rather long list of plugins. ClipboardExtendedPlugin.bundle CroquetPlugin.bundle CurlPlugin.bundle FloatMathPlugin.bundle FT2Plugin.bundle IA32ABI.bundle KedamaPlugin.bundle KedamaPlugin2.bundle LocalePlugin.bundle mpeg3Plugin.bundle ObjectiveCPlugin.bundle OggPlugin.bundle PrintJobPlugin.bundle QuicktimePlugin.bundle RomePlugin.bundle SerialExtendedUnixPlugin.bundle ServicesPlugin.bundle SpellingPlugin.bundle SqueakFFIPrims.bundle TestOSAPlugin.bundle UnixOSProcessPlugin.bundle -- =========================================================================== John M.

Yes, Mariano made a ConfigurationOfOCompletion. Otherwise, just loading the latest OCompletion package on top of the old one should work too.

Re: [Pharo-project] Sockets in Pharo CollaborActive Book
by Schwab,Wilhelm K Sept. 8, 2010

Sept. 8, 2010

Stef, Noury, Thanks for doing this, and for the preview! Sometimes being a good friend means getting tough, and it's time for that. You are doing a great job of writing up how to create poorly designed socket applications. They are poorly designed because of what we inherit from Squeak. Servers should not listen for a time period; they need to listen until told otherwise, and trigger events (notifications if preferred) when a client tries to connect, at which point a dedicated process accepts the connection - that process more or less is the server. Clients should try to connect and read until told otherwise, either by a watchdog thread or by a user. Nothing should block in either case except the calling Smalltalk Process. If a client program does not hang because of a non-responsive server, an interacting user has the opportunity to hit a cancel button and put an end to wasted effort, or a watchdog can run and similarly #erminate the offending thread. IMHO, we should not direct energy at documenting the current state of sockets; we should do the few remaining things to get something that really works. At the same time, we should try as much as possible to allow IrDA and OpenSSL to appear as options.

[Pharo-project] Magma in Pharo 1.1
by Mariano Martinez Peck Sept. 8, 2010

Sept. 8, 2010

Hi. I was trying the welcome workspace of Pharo 1.1 in order to install Magma but it fails. I am evaluating: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfMagma'; load. ((Smalltalk at: #ConfigurationOfMagma) project latestVersion) load The error was a Sintax Error in lazyX ^ x ifNil: [x _ Period or right bracket expected ->42] I attach screenshot. It seems the problem with the underscore as they are not allowed anymore as asiggment in Pharo 1.1. In order to appear in Pharo welcome workpsace this should be working. If someone makes the changes and updates de configuration please let me know (sorry but I don't have time to do it myself). Otherwise, I will have to remove it from Pharo 1.1 workspace as it doesn't work and makes confusion. Thanks Mariano

[Pharo-project] Please help!! Error: There is no free space in this set!'
by Mariano Martinez Peck Sept. 7, 2010

Sept. 7, 2010

I know this is a alraedy known issue: http://code.google.com/p/pharo/issues/detail?id=1628 I am trying to make SqueakDBX work in 1.1 and it doesn't work because of this. Each DBXConnection is registered in the WeakRegistry just to close the database connection in case they don't do it explicitly. This this, I have a: addObjectToGarbageCollect: anObject WeakRegistry default add: anObject. And in DBXConnetion >> connect, I call that method. Do you know how to solve the problem? I read the issue but I am uncertain what should I do nor if it is fixed. I think this bug is really important. Thanks Mariano
