Stepping through with GLORP Proxies
by Esteban A. Maringolo June 25, 2014

June 25, 2014

Does anybody else have issues while stepping through GLORP Proxy objects (collections in this case)? I simply can't use this feature unless the proxied collection was already materialized. I can't reproduce it right now, but it bites me everytime is step through blocks, because stepping into is really annoying :) Does anybody else have the same issue? This is Pharo 2. Esteban A.

Smalltalkhub is exposing private information
by Norbert Hartl March 3, 2014

March 3, 2014

When you look at someones page you can read commit messages of packages that belong to a private project. You can't see the project nor the package but it is listed in recent activities. I filed a bug https://code.google.com/p/smalltalk-hub/issues/detail?id=32 Norbert

Update Fuel documentation
by Nicolas Cellier Feb. 17, 2014

Feb. 17, 2014

This page http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.9/Documentation/… obsolete information, at least for Squeak installation. This is because ConfigurationOfFuel-MaxLeske.178 still points to old repository http://ss3.gemstone.com/ss/Fuel.html which has been drained... ConfigurationOfFuel-MartinDias.209 should be a better starting point. In latest Squeak trunk there is another problem: lack of squeak4.5.x support both in ConfigurationOfFuel and MetacelloSqueakPlatform>>defaultPlatformAttributes. But it's another problem, not related to documentation

Fuel: fix for Squeak trunk
by Nicolas Cellier Feb. 17, 2014

Feb. 17, 2014

I have an easy fix for Fuel on Squeak trunk. It concerns the FuelCompatibility layer, so I hesitate to publish on Pharo fogbugz... Is there a dedicated bug tracker? What is the preferred procedure? Nicolas

100% CPU usage on image resume
by Holger Hans Peter Freyther Feb. 16, 2014

Feb. 16, 2014

Hi, I saved an image and today I wanted to resume it. Everything comes up, for a second I can interact with it (e.g. move a window) but then the pharo VM goes to 100% CPU usage. I let it run while writing this email and it eventually aborted: C stack backtrace: ./pharo[0x80a0c0c] ./pharo(error+0x19)[0x80a0f69] ./pharo[0x80785d3] ./pharo[0x80786e1] ./pharo[0x8078f10] ./pharo[0x8090d97] ./pharo(ceStackOverflow+0x6a)[0x80946ea] [0x76ef122e] ./pharo(interpret+0x7a6)[0x8094f36] ./pharo(main+0x2b3)[0x80a18b3] /lib/i386-linux-gnu/i686/cmov/libc.so.6(__libc_start_main+0xf5)[0xb74bb8c5] Smalltalk stack dump: 0xbfd5c610 M SmallInteger(Number)>negative 0x3841=7200 0xbfd5c630 M SmallInteger(Integer)>* 0x3841=7200 0xbfd5c64c M SmallInteger>* 0x3841=7200 0xbfd5c668 M Duration>asNanoSeconds 0x790ddef4: a(n) Duration 0xbfd5c684 M Duration>= 0x7fe004a0: a(n) Duration 0xbfd5c6a0 M DateAndTime>asLocal 0x7fe00488: a(n) DateAndTime 0xbfd5c6c0 M DateAndTime>- 0x7fe0040c: a(n) DateAndTime 0xbfd5c6dc M DateAndTime>asSeconds 0x7fe0040c: a(n) DateAndTime 0xbfd5c700 M DateAndTime>< 0x78d2a5f8: a(n) DateAndTime 0xbfd5c71c M DateAndTime(Magnitude)>> 0x7fe0040c: a(n) DateAndTime 0xbfd5c73c M TimerScheduler>fireTimers: 0x77ef49ac: a(n) TimerScheduler 0xbfd5c764 I [] in TimerScheduler>runTimers 0x77ef49ac: a(n) TimerScheduler 0xbfd5c780 M BlockClosure>on:do: 0x78d2a60c: a(n) BlockClosure 0xbfd5c7a4 M [] in Dispatcher>dispatch 0x77ef4764: a(n) Dispatcher 0xbfd5c7c4 M BlockClosure>ensure: 0x78d2a798: a(n) BlockClosure 0xbfd5c7f0 I [] in Dispatcher>dispatch 0x77ef4764: a(n) Dispatcher 0xbfd5c810 I [] in BlockClosure>newProcess 0x78d2a634: a(n) BlockClosure Most recent primitives stack page bytes 4096 available headroom 3300 minimum unused headroom 3508 (last object overwritten) Aborted TimerScheduler/Dispatcher is code of mine but I wouldn't understand why this code is getting blocked and would eventually cause a stack overflow? holger

by Stephan Eggermont Jan. 13, 2014

Jan. 13, 2014

Call for Participation in the Smalltalk Devroom at FOSDEM 2014. http://www.fosdem.org, please forward " A devroom for the Pharo, Squeak, Amber, GST, EtoilÃ©, Seaside, Moose Smalltalk projects & Newspeak as derived language. Smalltalk environments offer a very high development productivity, unmatched by their successors. Come do some pair programming with us and experience yourself the advantages of a real OO environment" The meetup will take place Saturday, February 1, 2014, from 9AM until 5PM, building AW. This room has 72 seats, a VGA video projector and wireless internet. More information will be available later. If there are volunteers to record video content, the FOSDEM organization kindly offered to provide needed equipment & instructions. Please let me know if you would be willing to spend some time pointing a camera at a speaker. Proposals on content and format are welcome. People interested in running a session should send me an email at stephan ( @ ) stack ( dot ) nl with 'FOSDEM2014â in the subject and the following information: - Their name - The project they are associated with - A short bio, to be put on the website along with their speaker name - (optionally) a picture of themselves - The title of their session (which will go on the website and in the booklet) - A abstract describing the session in further detail. - The desired length of the session. - The desired time slot in which they want to hold the session. I will send out updates on a regular basis to the lists and anyone stating his interest. Suggested values for the duration are 55min, 25min, 6m40 (Pecha Kucha). The desired time slot is meant to help you prevent conflicts with other dev rooms in which you might have a talk or your travel arrangements. There are alternative, non smalltalk-specific tracks available: lightning talk and the main track The deadline for submissions is December 31, 23:00 GMT+1. Devroom related URLs: http://www.pharo-project.org http://www.squeak.org/ http://etoileos.com/ http://www.seaside.st/ http://smalltalk.gnu.org/ http://www.moosetechnology.org http://amber-lang.net http://newspeaklanguage.org/ http://www.esug.org First proposal already arrived: Stefan Marr proposed: I could give a presentation on SOM (Simple Object Machine) Smalltalk. I would especially go into detail of the Truffle-based and the RPython (PyPy) based implementations to show modern ways of language implementations with the goal of achieving high performance.

I guess this is not yet enough to be able to create a new CI job ? Do I still have to wait for a manual approval ?
