But it would be interesting to try something similar to this with the LibGit bindings :). I might take a stab at this.. Right now itâs tied to the GitHub API which is kind of a bummer, but for prototype purposes itâs alright in my opinion.

This sounds suspiciously like the same thing we had with Fuel 2 or 3 years back. Search for "Frequent SegFaults in PharoVM with Pharo 3.0â.

What is the size of the .image when you are about to run GC?

Re: [Pharo-dev] Does Pharo stores original author of methods?

by Nicolas Cellier

It's not Monticello per se. It's the backend (the server) which is too naive. The .mcz must be considered as a unit of exchange between the server (the repository) and the client (the working copy). And please note that in Monticello, it's not the only way to exchange data, it can also be a .mcd (a diff). Nothing forces the server to store the .mcz as is. That's just a naive implementation. Chris Muller demonstrated how to use a database (magma) as backend... 2015-11-23 12:12 GMT+01:00 Marcus Denker <marcus.denker(a)inria.fr>: > > > On 22 Nov 2015, at 20:12, EuanM <euanmee(a)gmail.com> wrote: > > > > Is there any reason against amending Monticello to store and save all > > author's names? > > It does. *If* you have all the versionsâ¦ but doing anything with âall the > versionsâ > is so slow (you need to download them, unpack themâ¦) that we do not even > have > a tool to show the history of a method. > (getting the oldest should be simpler, if you have complete history+this > .mcz is > there). > > Monticello is meant to be a system to save the complete history of a > project > (if you keep all the MCZ available), but the idea to save every tiny > revision as > a complete snapshot, zip compresses, makes it near impossible to do > anything > with the history in practice. > > With today disks, a practical SCM would allow anyone to have the *complete* > history on the local disk.

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
