Swazoo - LGPL or MIT?
by Bruce Badger 27 Mar '08

27 Mar '08

Swazoo is licensed under the LGPL, it says so right on the SourceForge project and it was on that basis that we did some work with it. http://sourceforge.net/projects/swazoo/ And has been confirmed in discussions on cls in 2000 and more recently in 2006 ... yet in the Squeak Map package loader it is listed as having an MIT licence. It seems to have been mis-categorised in Squeak Map. How can this be fixed? -- Make the most of your skills - with OpenSkills http://www.openskills.org/

On the swazoo list
by Bruce Badger 26 Mar '08

26 Mar '08

On the Swazoo list, from which I have been excluded, Janko is asking the question of whether Swazoo should be re licensed under the MIT license rather than the LGPL. Regardless of the outcome of this, the current status is that Swazoo is under the LGPL. Only new versions of Swazoo would be affected by any "relicense" and only then if all code contributed by people who were not included in the discussion were removed. So far, the discussion does not appear to include any of the other original contributors to Swazoo. Clearly, as I am excluded from the discussion there can be no question of any of my code being subject to any "decisions" on the swazoo list. The same would apply to any other contributor too. Copyright to the rescue. You know, I do agree that there needs to be clarity in licensing. With Swazoo, I thought we had that, since from day one it has been under the LGPL which I thought was a pretty open license (I share Paolo's view on that). But this idea of grabbing other people code and claiming that it is licensed as you please is not what I signed up for. It looks like some kind of software mugging from where I sit. -- Make the most of your skills - with OpenSkills http://www.openskills.org/

Installer problem with .mcm files and possible solution
by Sebastian Sastre 26 Mar '08

26 Mar '08

Hi there, I was trying Installer to customize some images I need. The .mcm file I needed to load was causing trouble. Installer in mcThing makes version workingCopy repositoryGroup addRepository: mc for every version but if instead of a regular package you asked for a .mcm then it will give you a DNU on #workingCopy So I've patched it unelegantly perhaps to: (version isKindOf: MCConfiguration) ifFalse:[ version workingCopy repositoryGroup addRepository: mc]. and it worked fine. cheers Sebastian Sastre PD: here is the whole method patched mcThing | files fileToLoad version count | self logCR: 'finding ', self package asString, '...'. "several attempts to read files - repository readableFileNames sometimes fails" count := 0. fileToLoad := nil. [count := count + 1. (fileToLoad = nil) and:[ count < 5 ] ] whileTrue: [ files := mc readableFileNames asSortedCollection: self mcSortFileBlock. fileToLoad := files detect: self mcDetectFileBlock ifNone: [ nil ]. ]. version := mc versionFromFileNamed: fileToLoad. (version isKindOf: MCConfiguration) ifFalse:[ version workingCopy repositoryGroup addRepository: mc]. mc creationTemplate: mc asCreationTemplate. self log: ' found ', version fileName, '...'. ^ version

26 Mar '08

Hello All, I need a file selection dialog , but when using FileList, FileList2 o FileChooser, I get a list of remote sites like Squeakland, SuperSwiki, or Squeak related ftp sites that have no meaning for the users of my app. How can I get rid of that ? What I use now (from FileChooser example1): | fc stream | fc := FileChooser new. fc initalizeAsDialogBox. stream := fc open. Thanks in advance, Javier Reyes

linux beta testers for GStreamer?
by John M McIntosh 26 Mar '08

26 Mar '08

Ok I'm far enough along so that I need some beta testers to try the SUnits for the GStreamer plugin on Linux. Right now the SUnit runs thru about 32 tests to check the sanity of the API and functionality of playing *.ogg files it has created, or downloaded from http://www.gutenberg.org/files. This of course works on my os-x macintel machine with GStreamer installed but I need to broaden the test base a bit. Other issues. (a) I have not written this for 64bit linux, I don't have a test machine setup for that. Likely some work is required to rework the SLANG so that it's 64bit pointer aware versus being 32bit aware. (b) GStreamer is not part of the standard OS-X installation, installing it requires practice with the cmd-line, and lots of time. (c) I have no plans to test or make this work on Windows. -- = = = ======================================================================== John M.

Bezier filled shape rendering artifacts
by Igor Stasenko 26 Mar '08

26 Mar '08

Hello, i spent a few hours to implement new morph (BezierMorph) , partly to see how balloon draws bezier shapes, partly to be able to edit all cubic bezier parameters. What i found that at some specific point it produces a visual artifacts by infinitely extending a single horizontal lines. Can't say, is this bug of balloon plugin or it's because of inaccuracies , which can be eliminated/avoided by ST, without fixing plugin? I'm specially making sure that all segment joints having same coordinates (endpoint of segment A is equal to starting point of segment B, which follows A). Also shape is closed. To reproduce a bug, file in a morph. Put it on desktop, then right-click -> convert to filled shape. You can also edit a morph's points (by choosing 'edit shape' in context menu) and see how horizontal line appears and disappears depending on vertex position and segments curvature. Btw, time to time i see same artifacts in hint popups which using filled curved shapes too. -- Best regards, Igor Stasenko AKA sig.

Squeak-Map may be down?
by Kum Sackey 26 Mar '08

26 Mar '08

I posted this message on the Seaside mailing list, and was told that Squeak map might be down. I'm trying to install the Seaside Magma Helper through the Universe package browser, however always fails with: Syntax Error: 'Nothing more expected -><' when it tries to install the dependency: 'Logging version 3.11' When I checked the debugging to see what it was actually doing... it seemed to me that the SqueekMap package server is down, or responding badly. This is the response from the server: DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> Argument expected -><html><head> <title>502 Proxy Error</title> </head><body> <h1>Proxy Error</h1> <p>The proxy server received an invalid response from an upstream server.<br /> The proxy server could not handle the request <em><a href="/accountbyid/4f504af8-92c9-4c5a-9a17-ec2e0d374620/files/InstallerInstallLogging.st">GET /accountbyid/4f504af8-92c9-4c5a-9a17-ec2e0d374620/files/InstallerInstallLogging.st</a></em>.<p> Reason: <strong>Error reading from remote server</strong></p></p> </body></html> -- ------- K.

MC bugs in 3.10
by Michael van der Gulik 25 Mar '08

25 Mar '08

Hi all. I'm trying to release a package that will load into 3.10. However, it won't work because: - I've changed instance variables PluggableTreeSpec in the ToolBuilder-Kernel package available from the Universes browser. The MC that is packaged with 3.10 does not properly recompile the code, so bytecodes in methods are now referring to the wrong instance variables. - So I try adding a postscript to the package to recompile that class. In the Monticello UI, I click on Scripts -> edit postscript, and I get a DNU. Are these known bugs? Gulik. -- Michael van der Gulik <mikevdg(a)gmail.com>
