OSX el capitan - SIP
by recursive68＠gmail.com Jan. 4, 2016

Jan. 4, 2016

Hi, OSX el capitan implements System Integrity Protection: https://en.wikipedia.org/wiki/System_Integrity_Protection One of the effects of this is you can no longer modify DYLD_LIBRARY_PATH for an OSX application. I use a FFI wrapper to load and use an Oracle library in Pharo but this requires modification of the DYLD_LIBRARY_PATH to work. Up until now I could do this by adding a plist config file to /Library/LaunchAgents for the Pharo application which modified DYLD_LIBRARY_PATH. This no longer works because of SIP. Launching Pharo from a terminal having modified DYLD_LIBRARY_PATH via .bash_profile works as required but this is less than ideal. Anyone know of any other way of doing this so I can launch Pharo directly as an OSX application ? Thanks

Versionner and package dependencies
by Ferlicot D. Cyril Jan. 4, 2016

Jan. 4, 2016

Hi, I wanted to use versionner to manage some existing configurations but in one of these configuration there is some dependencies on packages that have no project. For example in the baseline there is: spec package: 'Glamour-EyeSee-Presentations' with: [ spec requires: #('EyeSee'). spec repository: 'http://smalltalkhub.com/mc/Moose/Glamour/main' ]. But in versionner I can only add a project as dependency. Is there a way to do such a thing or is it a future feature of versionner? -- Cyril Ferlicot http://www.synectique.eu 165 Avenue Bretagne Lille 59000 France

Adding description doc for Catalog browser projects
by Dimitris Chloupis Jan. 4, 2016

Jan. 4, 2016

It has just occured me to that since meta repo is public and anyone can commit to it, is it ok if I add descriptions to projects that have none ? Because I am tried of seeing a project on Catalog Browser with no idea what it does. But i thought to ask permission to edit other people's configurations, though I wont be touching the configurations themselves only add descriptions to projects I find interesting yet they have not description. Is that ok with you ?

[IMPORTANT] Starting migration to Spur VM
by Esteban Lorenzano Jan. 3, 2016

Jan. 3, 2016

We will start migration to Spur today. To complete it, we will require some time, specially to adapt the CI and check everything is ok. Spur will allow us to do a big step forward in Pharo development, in the concrete you will see it immediately for this: - We have noticed a speed increment of 100% in tiny benchmarks (and according to Eliot, it will be at least 35% in general on the system). - No more GC stops (noticeable when running large systems) - We will be able to scale our systems up to 2G memory consumption without loosing performance. But, this will have some drawbacks in the first times: 1) VM will not be compatible between versions anymore: Pharo 5.0 will have a Pharo Spur VM associated (and they are not compatible). - There WILL NOT be a "non-spur" version of Pharo 5.0. Once completed the transitions, this will be the only one. 2) NativeBoost-FFI implementation has been replaced with a new implementation who relies in ThreadedFFIPlugin and IA32Plugin. While we worked a lot to do this transition as painless as possible and we achieve a good level of backward compatibility (most uses of #nbCall: should work out of the box), there are some problems we cannot solve: - there are some stuff not possible to compatibilise, notably: - Structures now need to inherit from FFIExternalStructure - Arrays now are now shadowed - in general is a bit slower (impossible to compete with ASM) but in general is not perceptible. - THERE WILL BE BUGS AND NON-IMPLEMENTED FEATURES: Current implementation is validated with Athens and even Roassal was working, but of course that does not covers all cases. 2.1) ASMJIT will be removed from system and put in a separated packages. NOTE: There will be a blog post explaining FFI-NB architecture during the week. 3) There are more or less 70 new failing tests, some of them important than we need to fix as soon as possible. Please, please, please, help us with them :) 4) In general we foresee the system will became unstable some weeks, before it gets back to normal. Please be patient. 5) You will need to adapt your Pharo 5.0 related apps and CI processes (to take care about new VM). Some programs will stop work at all (for example, I think Pharo-launcher will need to be adapted).

Hi Pharoers I want to thank all of you for making Pharo what it is becoming: a Really Cool system and community. I wish you good health and a lot of business or fun in Pharo :). 2016 will see many changes that are planned to name a few - Pharo 5.0 with Spur - Pharo 5.0 with 64 bits - Bootstrap Pharo in production - SDL full integration - Git and Package validation - A full Mooc on Pharo - A couple of cool tutorials And I'm sure many unexpected project and libraries... The consortium should continue to grow so if you are hesitating to join please do. Stef

Pharo 5: Bug in removing key combinations
by Johan Fabry Dec. 30, 2015

Dec. 30, 2015

Hi all, Miguel and I found a bug in removing key combinations on a morph. Now they are global, while in Pharo 4 this was not the case. Consider the following code: | morph | morph := RubScrolledTextMorph new. (morph textArea) removeKeyCombination: $s command; removeKeyCombination: $s control; on: $s command do: [morph flash ]; on: $s control do: [morph flash ]. morph openInWorld. In the morph, cmd-s will cause a flash, as expected. However in other windows (or browsers and playgrounds least) the original shortcut is lost, only a s character is added to the text field. I did not see it on fogbugz so I would like to announce it here before I open a case, in case (heh) I missed it. So the question: is this a known bug? ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile

Block that doesn't leak memory
by webwarrior Dec. 29, 2015

Dec. 29, 2015

BlockClosure objects hold reference to object that created them via outerContext receiver. This can cause memory leaks when moving blocks around/deepcopying/serializing. Is there a way to get "lightweight" block that has empty outerContext (like when executing code in Playground) or is there another class for such "lightweight" blocks somewhere? Obviously I'm talking about blocks that don't reference variables in enclosing scope and don't do nonlocal return. -- View this message in context: http://forum.world.st/Block-that-doesn-t-leak-memory-tp4868529.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

[OT] Dolphin 7 opensourced
by Torsten Bergmann Dec. 29, 2015

Dec. 29, 2015

Hi, just as an info and in case you missed it but might be interested: Dolphin Smalltalk for Windows 7 will be released open source (MIT licensed) on GitHub today ([1]/[2]). The sources for both the image and the virtual machine will be available. For those who do not know it: Dolphin is a Smalltalk system for Windows provided by Andy Bower and Blaire McGlashan from www.object-arts.com The article from BitwiseMag [3] gives an overview. The existing Dolphin 6.2 codebase was brought by Andy Bower now under Git and compiles completely under VisualStudio Community 2013. This is a new version, Dolphin 7, that is modelled off the previous X6.1 Professional Edition (although you can choose to build Dolphin Community Edition from it if you like). Have fun T.
