[Pharo-project] Issue # 1498 "Collections should not accept non integer indexes"
by csrabak＠bol.com.br Dec. 2, 2009

Dec. 2, 2009

I'm trying to follow the directions given at: http://code.google.com/p/pharo/wiki/HowToContribute. However, after the SLICE asks for the first comment, it freezes the image and the small window "Writing definitions" stays at 50% progress and nothing happens then. So I'll resort to the alternative plan, which is to send the changeset to this list. On a core image update #11067 the Collection tests are all green. Running all tests show one error and two failures not related to the changed methods. -- Cesar Rabak

I am not expert in Morphic, but I feel there is a bug in how exceptions in Morph are handled. Create a subclass of Morph and put a "self halt" (or "1/0") in the drawOn: method. Open the morph and it will appear in red, telling that there is an error in the render loop. Now, for some reason, when blocks are heavily, the image freeze. I tried to isolate the error (i.e., without Mondrian), but I could not figure out how to do it.

[Pharo-project] [Pharo-Project] Monticello package corrupted
by Hernan Wilkinson Dec. 2, 2009

Dec. 2, 2009

Hi, I'm moving code from Pharo to GLASS using Monticello, but in some packages the code that is read by GLASS is not correct, it has 0s in it. For example, instead of 'to' it has 't o ' (where spaces are zeros) If I try to unzip the monticello package, I get a CRC error on the source file... Does anybody heard about this error before? Thanks, Hernan.

[Pharo-project] Committing resource files with Monticello or along Monticello packages
by Simon Denier Dec. 2, 2009

Dec. 2, 2009

Hi there I would like to know if you people have some tricks or clever strategies to commit resource files (binary, icons, big text files) along monticello packages. And how do you load such files along monticello packages. My use case: I have a big text file with data, which I use as a model to run some tests. I don't want to store this information in the body of a method. -- Simon

[Pharo-project] Continuous Integration Server for Pharo?
by Bart Gauquie Dec. 2, 2009

Dec. 2, 2009

Dear all, I come from a Java world and there we use for instance : http://hudson-ci.org/ to do a continuous integration build. Which means all latest code gets updated, all test ran & if build successful, the code is tagged (so you can take the code again from a successful build). It also provides a nice GUI, and lets you inspect previous builds, the results from that build, ... . In Pharo, I did not directly find an alternative, and therefor, also as an exercise, I tried to build one myself. The primitive, but working result so far is: http://www.squeaksource.com/BuildBot. This project depends on BBProjectDescription, which defines class BBBuildProjectDescription with defines: - BBBuildProjectDescription>>allProjectPackageNames - BBBuildProjectDescription>>installLatestWithDependencies - BBBuildProjectDescription>>buildsClassToPutVersionsOn What buildbot then does is using a BBBuildProjectDescription , checkout all latest code, run the tests for all these packages & , if successfull, take the buildsClassToPutVersionsOn and add a new method on it, describing the exact package numbers : for instance: BuildBotMockProjectBuilds class >> packagesForBuild20091127102654 ^#(('TODO' -> 'TODO-BKBAG.5.mcz') ('BuildBtMockProject' -> 'BuildBtMockProject-BartGauquie.7.mcz') ). Using this information I can easily install this exact version. Furthermore creating a release is then just creating for instance a class BuildBotMockProjectReleases with: BuildBotMockProjectReleasesclass >> release_1_0 ^BuildBotMockProjectBuilds packagesForBuild20091127102654 I am in fact 'tagging' a group packages that belong together and work together. So I can rollout this exact versions of the packages to some image automatically. However, Today I noticed that there already existed a project: http://www.squeaksource.com/TestServerSimple which more or less does the same thing. The only thing it does not do, or I did not find it, is to version the build, so that you can restore a project again ; a project which is consisting of a number of packages which are compatible and for which all tests ran. Is there a way to do that in TestServerSimple? Furthermore, are there any other projects that do a similar thing I'm not aware of? Is there any default way in Pharo to build a project which consists of multiple packages that each have different versions? I've seen MetaCello & Gofer as some other way 2 load groups of packages, but no integration into some kind of ci tool. This kind of automated ci server seems 2 me an essential tool in Pharo.

[Pharo-project] lukas-renggli.ch down, mirrors exists ?
by laurent laffont Dec. 2, 2009

Dec. 2, 2009

Hello, I want to check if there's updates to Slime package as I faces several bugs but sources.lukas-renggli.ch seems to be down. Is there a mirror ? About the bugs (Slime-lr.24,current pharo rc1 web image), when I select refactor > code critics: - it seems that ParserTreeSearcher has been renamed to RBParserTreeSearcher. Thus there's several errors like WAChangesStateWhileRenderingRule>>initialize (ParseTreeSearcher is Undeclared) - this done, I have the error: AnObsoleteParseTreeSearcher(Object)>>doesNotUnderstand: #executeTree:initialAnswer: (from RBAssignmentIfTrueRule>>checkMethod:) How do I save a stack trace to a text file (or clipboard) from the debugger ? Regards, Laurent Laffont
