[Pharo-project] Cross compile Window from Unix/Mac os
by Jean Baptiste Arnaud July 7, 2011

July 7, 2011

Since the last Igor ( thank ) update it 's possible to cross compile windows VM(last version) from MacOs and Unix. Using Mingw and cmake. Now, i do for Cog, and for ARM9 processor. My process imply to fix some window file cause some include are wrong, then it the cross compiler don't find some include beginning by Uppercase(cause the file isn't beginning by uppercase). In /Platform/win32/vm/sqWin32Intel.c #include <float.h> instead #include <Float.h> in /Platform/win32/plugin/SocketPlugin/sqWin32NewNet.c #include <ws2tcpip.h> instead #include <Ws2tcpip.h> Regard Jean Baptiste Arnaud jbaptiste.arnaud(a)gmail.com

The resultant kernel and gofer images will be bigger. The question is if we will shrink this tables by default. I am in general not happy how resources are right now stored in the image... the only way right now is to either have them just there as objects, non-recreateble or people store stuff (fonts, bitmaps) as strings (or ByteArrays) in methods. This is not nice... but of course MC can store it and so its the only option. We should think about having an in-image, virtual file-system with all the static stuff... maybe this could even be per package and serialized with MC as part of the package? The MC packages now have already two sets of duplicated data: source (in the .st file) and the MC History data... which should not be underestimated: MC wastes right now 4MB of 13.5 MB in 1.4, In addtion, the fact that we have to wirite to .changes when loading a package is far from nice... it would be better of packages would be self-contained and the system would get the source from them.

[Pharo-project] Pharo Announcements and WADynamicVariable do not play nice
by Danie Roux July 7, 2011

July 7, 2011

Hi all, We use Announcements in our Seaside app. I've upgraded our Pharo image (from an ancient one) and the upgraded image looses the user's session. This issue is here: AnnouncementSubscription>>deliver: anAnnouncement " deliver an announcement to receiver. In case of failure, it will be handled in separate process" ^ (self handles: anAnnouncement class ) ifTrue: [ [action cull: anAnnouncement cull: announcer] on: Exception fork: [:ex | ex pass ]] Because of the catch-all, WARequestContext can't do its fancy footwork to manage thread-local variables. What is the rationale behind this? I removed the error handling. -- Danie Roux *shuffle* Adore Unix - http://danieroux.com

[Pharo-project] WindowOrganizer integration problems
by laurent laffont July 7, 2011

July 7, 2011

Hi, As work from Gary about grouping windows has been integrated in 1.4, I try to use it for TWM. If you load: Gofer it squeaksource: 'TilingWindowManager'; package: 'TWM'; load. StandardWindow new addMorph: GroupWindowMorph new fullFrame: (LayoutFrame fractions: (0@0corner: 1@1 )); openInWorld. You can drag and drop windows in the GroupWindowMorph to tab them. But I cannot find why GroupWindowMorph does not fill all the window....... Gary ? Then I want to use GroupWindowMorph in a DockingBar. There's some initial work in DockingWindowMorph but I'm stuck with the space fill problem.

[Pharo-project] [Jenkins] State of transition Hudson -> Jenkins
by Marcus Denker July 6, 2011

July 6, 2011

State of transition Hudson -> Jenkins ============================= We are slowly (step by step) moving builds from Hudson to Jenkins. the last days e.g. Coral (the scripting engine), RPackage, Nautilus... https://ci.lille.inria.fr/pharo/ The largest thing to move will be the VM autobuilt... that will be done later. Jean Baptiste Arnaud started with a setup for regression testing. https://ci.lille.inria.fr/pharo/job/Pharo%201.4%20Regression%20Tests/ This means "doing something slow" "run all tests" get new image "doing something other" "run all tests" The idea here is that this will be used for the following -> recompile the image -> decompile and recompile the decompiled code -> pretty print -> condense sources -> condense changes .... On the TODO list we have -> test the compiled VMs by running all tests on all plattforms -> update the One-click build script with the last good VM -> update the VM used to do everything with the self-build vm The goal is of course to have that what we release be build completely without human intervention, after every commit (either VM source or Image level change). In addtion, this setup will be available for others to use. This way students can easily clone the VM source and set up Continuous Integration for their research Fork. This will than make it far far easier for people to invent cool stuff that needs VM changes, like e.g. this: http://scg.unibe.ch/archive/papers/Lien08bBackInTimeDebugging.pdf or http://rmod.lille.inria.fr/archives/papers/Arna10a-Tools2010-ReadOnlyExecut… The problem right now is that all the code is "somewhere" and just picking up where the student left is a huge amount of work... with Git and autbuild, this will get much much better. (and it simplifies the life of the student a lot... autobuild, easy to track changes in the upstream...) JB already successfully builds his Handle VM: https://pharo-ic.lille.inria.fr/hudson/job/Handles/ So we are getting there.

[Pharo-project] reloaded Core failing tests
by Pavel Krivanek July 6, 2011

July 6, 2011

Hi Marcus, add this line to the initCore.st script on CI server: ActiveHand instVarNamed: #targetOffset put: 0@0. this will fix the testTargetPoint. The second and last failing tests is related to compressed unicode tables in the kernel image. I will prepare the code that will regenerate this tables. The second option is to disable call of privShrinkUnicodeTables method in privShrinkingProcess. The resultant kernel and gofer images will be bigger. The question is if we will shrink this tables by default. -- Pavel
