[Pharo-project] Fuel - a fast object deployment tool
by Martin Dias June 20, 2011

June 20, 2011

Hi all Last months I and Tristan have been working on Fuel project, an object binary serialization tool. The idea is that objects are much more times loaded than stored, therefore it is worth to spend time while storing in order to have faster loading and user experience. We present an implementation of a pickle format that is based on clustering similar objects. There is a summary of the project below, but more complete information is available here: http://rmod.lille.inria.fr/web/pier/software/Fuel The implementation still needs a lot of work to be really useful, optimizations should be done, but we'll be glad to get feedback of the community. = Pickle format = The pickle format and the serialization algorithm main idea, is explained in this slides: http://www.slideshare.net/tinchodias/fuel-serialization-in-an-example = Current features = - Class shape changing (when a variable has been added, or removed, or its index changed) - Serialize most of the basic objects. - Serialize (almost) any CompiledMethod - Detection of global or class variables - Support for cyclic object graphs - Tests = Next steps = - Improve version checking. - Optimize performance. - Serialize more kinds of objects: -- Class with its complete description. -- Method contexts -- Active block closures -- Continuation - Some improvements for the user: -- pre and post actions to be executed. -- easily say 'this object is singleton'. - Partial loading of a stored graph. - Fast statistics/brief info extraction of a stored graph. - ConfigurationOfFuel. - Be able to deploy materialization behavior only (independent from the serialization behavior) = Download = In a Pharo 1.1 or 1.1.1 evaluate: Gofer new squeaksource: 'Fuel'; version: 'Fuel-MartinDias.74'; version: 'FuelBenchmarks-MartinDias.4'; load. = Benchmarks = You can run benchmarks executing this line (results in Transcript): FLBenchmarks newBasic run. Thank you! Martin Dias

by StÃ©phane Ducasse June 19, 2011

June 19, 2011

Hi Sven with igor we went over the start up list and we saw that ZnServer resgiter all subclasses of ZnServer. We think that it would be better to have a list of servers to be registered and that users can decide. What do you think? Stef

[Pharo-project] Tiling Window Manager - status update
by laurent laffont June 13, 2011

June 13, 2011

First thanks to all people that send patches (and tests !!). Still not haven't merged all of them - don't hesitate to post in repository so code is not lost. Yes I will merge layout policies. Gofer it squeaksource: 'TilingWindowManager'; package: 'TWM'; load. (Smalltalk at: #StandardUITheme) beCurrent. (Smalltalk at: #TWMBar) showTWMBar:true. Tested on PharoCore 1.2 and Pharo 1.3. Now this has support for world snapshot, that means you can arrange the windows and take a snapshot of the layout. Then you can restore these layouts later. (icons camera, <, > and trash). I'm not entirely satisfied with this, thanks for feedback. In Pharo 1.3 there's initial integration with KeyMapping. To load: Gofer it squeaksource: 'ShortWays'; package: 'ConfigurationOfKeymapping'; load. (Smalltalk at: #ConfigurationOfKeymapping project version: #bleedingEdge) load. Then in settings browser > Keymappings > Tiling Window Managers you have all actions of the dock mapped. Not all shortcuts are working, don't know why, if people can test and find good shortcuts thank you. Creating a nice Metacello Configuration for TWM will be appreciated :) Cheers, Laurent Laffont - @lolgzs <http://twitter.com/#!/lolgzs> Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/ Developer group: http://cara74.seasidehosting.st

[Pharo-project] hudson for seaside broken [WAS] Fwd: [Hudson] Updates
by Mariano Martinez Peck June 6, 2011

I guess Dale could take a look when he comes from holidays cheers mariano ---------- Forwarded message ---------- From: Marcus Denker <marcus.denker(a)inria.fr> Date: Mon, May 9, 2011 at 11:40 AM Subject: [Pharo-project] [Hudson] Updates To: An open mailing list to discuss any topics related to an open-source Smalltalk <Pharo-project(a)lists.gforge.inria.fr> Hudson Updates ============= -> I fixed the build of 1.2 Full. For the Future, I would like to establish a new rule that a failing project is removed (with all its dependencies) from Hudson after 2 weeks of faling builds. A Project with a failing build over a long has proven to the world that nobody is interested in it. In addition, automatic builds don't make sense if they are broken all the time. -> Pharo Clients now are build for 1.3 in addition to 1.2 https://pharo-ic.lille.inria.fr/hudson/view/Pharo-Clients/ NOTE: Seaside is broken. This is due to MetaCello config that needs to be done for 1.3. It would be nice if someone would take the lead in fixing this.

[Pharo-project] tests ui errors in headless mode
by Tudor Girba June 6, 2011

June 6, 2011

Hi, We have some smoke tests in Moose that basically spawn a UI and check for Error. This used to work when running headless in Pharo 1.2 but now they fail in Pharo 1.3. I believe this has to do with the new changes in the UI Manager, but I do not know what to do. To reproduce the problem, you can simply call a Pharo-1.3.image in headless mode and file in the attached st file that: - installs a simple test: HeadlessTest>>testStartup self shouldnt: [1 inspect] raise: Error - loads HudsonTools - runs the test and outputs the XML file report - although the test should pass, it raises the error: HeadlessStartupTest(TestCase)>>signalFailure: HeadlessStartupTest(TestCase)>>assert: HeadlessStartupTest(TestCase)>>shouldnt:raise: HeadlessStartupTest>>testStartup HeadlessStartupTest(TestCase)>>performTest Can anyone help? Cheers, Doru -- www.tudorgirba.com "What is more important: To be happy, or to make happy?"

[Pharo-project] usability of Pharo and Squeak
by Andreas Wacknitz June 4, 2011

June 4, 2011

Hi all, I have convinced a friend to take a closer look at Pharo 1.2.1 and Dolphin Smalltalk. He is an experienced Java developer. After some time he started to complain about Pharo. I was discussing with him and now think that he has some valid points. His biggest complaint is: "Why does Pharo always show windows at sizes and positions I don't want?" I answered him: You could set the standard window size in the class RealEstateAgent and furthermore you can create or change >>initialExtent methods in every class that is involved. But his answer was: Why should I do that? It's the responsibility of an IDE. I don't want to program elementary things of my IDE. Why is there no mechanism that let a user set the sizes and positions of windows? Netbeans and Eclipse are doing that nicely. Why isn't it possible in Pharo? After that discussion I now question my own way of using Pharo and Squeak. I have created some changesets that I used to file in when using a fresh image. But that seems stupid now... His second complaint was that he doesn't like the cluttered windows. While programming he had a lot of open windows and told me that he lost overview. Especially in Pharo he is complaining about minimized windows that are hard to distinguish. He better likes Dolphin with tabbed windows that are common in other IDE's. Regards Andreas
