vm crash in SmalltalkImage>garbageCollect

by Andrei Chis

Hi, With both the latest and stable vm I have an use case in which the vm crashed in SmalltalkImage>>garbageCollect. To set up an image that exhibits the failure , execute this with the latest pharo version: /pharo Pharo.image eval --save "{ { 'ConfigurationOfRubric'. 'Pharo'. 'Rubric' }. { 'ConfigurationOfGlamourCore'. 'Moose'. 'Glamour' }. { 'ConfigurationOfGTInspectorCore'. 'Moose'. 'GToolkit' }. { 'ConfigurationOfGTPlaygroundCore'. 'Moose'. 'GToolkit' }. { 'ConfigurationOfGTEventRecorder'. 'Moose'. 'GToolkit' }. { 'ConfigurationOfGTSpotter'. 'Moose'. 'GToolkit' }. } do: [ :spec | Gofer new smalltalkhubUser: spec second project: spec third; package: spec first; load ]." ./pharo Pharo.image config http://www.smalltalkhub.com/mc/Pharo/Pharo50Inbox/main ConfigurationOfGToolkitCore --install=3.2 Then attempting to run the following code triggers the failure: ./pharo Pharo.image eval --save "TestRunner open model packageSearchUpdate: 'gt-tests-inspector'; classSearchUpdate: 'GTInspectorExamplesTest'; runAll" Based on the trace below the failure happens when the test GTInspectorExamplesTest calls 'Smalltalk>>garbageCollect' in the setUp method. That call can be removed, however, in other runs the failure happens in other methods calling Smalltalk>>garbageCollect. Is it possible that this is a bug with the image (some broken object) or is it a vm bug? Cheers, Andrei andrei$ ./pharo Pharo.image eval --save "{ { 'ConfigurationOfRubric'. 'Pharo'. 'Rubric' }. { 'ConfigurationOfGlamourCore'. 'Moose'. 'Glamour' }. { 'ConfigurationOfGTInspectorCore'. 'Moose'. 'GToolkit' }. { 'ConfigurationOfGTPlaygroundCore'. 'Moose'.

Basic versioning of GitHub repositories from within Pharo

by Skip Lentz

Hi everyone, As part of my internship I am creating bindings to the GitHub API in Pharo. As a prototype and demo, I have created a small tool last week to do some basic versioning, namely checking out a version, committing a version and showing a log of commits along with a branch tree. Hereâs a screenshot: http://i.imgur.com/iMfWOvp.png <http://i.imgur.com/iMfWOvp.png> The repository of the bindings and the tool is here: http://smalltalkhub.com/#!/~Balletie/GitHub To load the tool into your image, execute: (ConfigurationOfGitHub project version: #development) load: #tool Keep in mind that this is tied to GitHub, since internally it uses the API. A nice side effect of this is that everything can be done in-memory. That is, thereâs no local copy on the filesystem. One does not even need git installed. That being said, feel free to take off with my prototype and make it work with e.g. the LibGit bindings in Pharo. Known bug: - When selecting a different repository from the dropdown while a version is also selected in the log, one gets a DNU. To work around this for the time being, just deselect the version before you switch repositories. Let me know what you think and feel free to ask some questions. Skip

Hi, Great. Please do not add any group. This is definitely a useful presentation, and it should be loaded by default with ConfigurationOfGlamour (not GlamourCore yet).

Hi Doru, Cyril has already copied glamour components for FASTTable in Glamour's repo. To load these, we can create a group in configOfGlamour to load glamour components and their dependencies (fasttable).
