Pharo image corruption and fatal VM error with Roassal
by Blondeau Vincent Aug. 3, 2014

Aug. 3, 2014

Hi, Yesterday, I was using GraphET (a part of Roassal) to do some charts and, today, when I wanted to reopen the image. And I got that : [cid:image001.png@01CFACAA.E0CB2060] It is *very* unpleasant... To reproduce the bug: 1 - You can do either: | builder | builder := GET2Line data: (0 to: 100) . builder y: [ :x | x*x ]. builder open. Or WorldMenu -> Roassal examples -> choose an item -> click on a graph . A TRMorph should be opened. 2 - don't close the graph and save the pharo image. 3 - Close the pharo image 4 - Reopen it I am under W7 x64 with the latest moose image and the VM available on the pharo.org website (http://files.pharo.org/platform/Pharo3.0-win.zip) from the 10 july. You will find the crash dump attached. Thankfully, I managed to open the image with a latest VM (http://www.mirandabanda.org/files/Cog/VM/VM.r3056/cogwin-14.29.3056.zip) Thanks a lot Eliot ! :) And I got this: [cid:image002.png@01CFACAD.350D7DB0] Thanks in advance Cheers, Vincent BLONDEAU ________________________________ Ce message et les pi?ces jointes sont confidentiels et r?serv?s ? l'usage exclusif de ses destinataires.

Hi, In the course of revamping the Pharo environment, we stumbled across the print it action and we (Andrei and I) decided to rethink it. [image: Inline image 1] You can find more details here: http://www.humane-assessment.com/blog/rethinking-print-it-in-pharo Let us know what you think.

Should nested mutexes work in Pharo 3.0?
by Marcel Taeumel Aug. 1, 2014

Aug. 1, 2014

Hi! :) I am playing around with Animations [1] in the Moose 5.0/Pharo 3.0 image [2]. Nested use of the same mutex seems to freeze the image. Should that work?

Smalltalkhub not serving any mcz files?
by pieter＠nagel.co.za July 31, 2014

July 31, 2014

Hi, It seems that www.smalltalkhub.com is not serving up any mcz files anymore. For example, all of the links from http://www.smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main just lead to "not found" error pages. Same with http://www.smalltalkhub.com/mc/smaass/Pharo3Sounds/main and http://www.smalltalkhub.com/mc/zeroflag/Teapot/main (projects chosen at random from www.smalltalkhub.com front page). Apologies if this is the wrong list; based on the archives this list seems to be the place where smalltalkhub errors have been reported in the past.

Android VM Status
by Jean Baptiste Arnaud July 31, 2014

July 31, 2014

Hi, I made some advance on Android StackVM (using the standard unix sources). :-) Last Unix Stack VM with last 40Pharo image (a little bit modified cause au no-NativeBoost and some constraint from the Android Sandboxing ). Content: - Somes lines of code change in SqUnixMain.c (using if define android, but not a lot, just for allow to load external lib :-). - 1 communication with java / C files, (will be split in two or three file one for printing debugging, one or two for core). - 1 external graphical plugins. vm-display-android, really short but for android, because the rendering is done by Android. All these plugins are includes (not deeply tested yet, but most of them should work): AndroidPlugin (for now I just allow to do debug printing from the image in the logCat), BitBltPlugin, B2DPlugin, BMPReadWriterPlugin, CroquetPlugin, DSAPrims, FFTPlugin, FileCopyPlugin, FilePlugin, FloatArrayPlugin, FloatMathPlugin, JoystickTabletPlugin, JPEGReaderPlugin, LargeIntegers,Matrix2x3Plugin, RePlugin, SecurityPlugin, JPEGReadWriter2Plugin, SocketPlugin, MiscPrimitivePlugin, ZipPlugin. And a lot of debugging. :-). Next step: - fixing all the Event. - Do a real Configuration generator to be able to generate from Jenkins using the NDK. - Then merge in the main PharoVM Git :-). - Do a configuration to allow older pharo image to run on it. Maybe older but I not convince yet. - And obviously a job for allow anybody to create a android package with it's own image :-) See you soon :-) Best Regards Dr Arnaud jbaptiste.arnaud(a)gmail.com
