Re: [Pharo-project] About a object life

Only for new objects? If so, you could add an instance variable to Object and store a timestamp. On 03.11.2012, at 15:26, Edgar J. De Cleene <edgardec2005(a)gmail.com> wrote: > Folks: > > I wish know how old a object is. > > Any have code for this ? > > Thanks in advance > > Edgar

Re: [Pharo-project] How to load MetacelloToolbox

by Francois Stephany

We looked a bit at OSProcess in 2.0 with Mariano on Friday. We tried to have clean loading (i.e., remove FileDirectory references + a couple of other stuff). We also spotted some inconsistencies in the ConfigurationOfOSProcess. I'm going to continue what we started but I don't think I will be able to make all the tests pass (if I remember well, they are not passing in 1.4 summer neither...) Where should I commit the changes?

Re: [Pharo-project] Are the any Fuel file analysis tools/techniques?

by Mariano Martinez Peck

Hi guys. Indeed, this is something we wanted since a long time and it has already been discussed: http://code.google.com/p/fuel/issues/detail?id=163 Unfortunately, nobody had time to do it. What we do have is written here: http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.8/Documentation/… but the visualization that does not work well if the graph is large. If your object graphs you usually serializer are around a known range of size, you can check after the serialization if that was the case, and if it was not, then debug it. Something you can do is to put a halt in FLSerialization >> #run just after doing the "self analysisStep.". At that point, you can inspect the instVar 'clusters'. You can see which clusters you have and each cluster understand #objects which answers all the list of objects associated to that cluster. If a cluster corresponds to a particular class you can also ask #theClass. But this only works for the serialization, not for the materialization.

Re: [Pharo-project] How to load MetacelloToolbox

by Dale Henrichs

Esteban, If I'm not mistaken the MetacelloToolBox is a candidate for inclusion to support Versionner. If you are getting Github stuff in Pharo2.0, then I am curious which version of Metacello you are using. The #stable version of Metacello doesn't include github. The github support stuff needs OSProcess and from what I understand OSProcess won't be included in Pharo2.0, so perhaps you are more concerned about the GitHub support than MetacelloToolBox? I really can't think of anything in MetacelloToolBox that makes it a "bad idea" to include in Pharo2.0. I think that you might be happier if you stuck with 1.0-beta.31.1.5 as that predates the github support.

Okay, I didn't think that there should be undeclared references showing up because of MetacelloToolBox ... a bug of some sort is more likely the root cause...

Re: [Pharo-project] How to load MetacelloToolbox

ConfigurationOfMetacello ... load: 'Metacello-ToolBox'. should doit, and the baseline says: package: 'Metacello-ToolBox' with: [ spec requires: #('Metacello-Base' 'Metacello-Core') ]; and the "already included" metacello should be what is in the 'batch' group (Base and some Github access stuff). And I insist, including MetacelloToolBox in the 2.0 core image is a bad idea...

Re: [Pharo-project] 20381 running the test does not work ...

by Camillo Bruni

There are a couple of things missing in the progress refactoring I started with sean - Job/ProgressBar should only use a single progress variable (0.0 - 1.0), no more unbounded min/max/current which leads to duplicate size calculations everywhere - The Visual part should be adapted to only take a single variable into account - The ProgressMorph only updates maximally every 50ms no matter how many change/updates it got - Make sure that concurrent progress are supported (currently only the last added progress morph is updated) On 2012-11-03, at 22:48, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > Ouch two problems! > > I'm also wondering why we have > > SystemProgressItemMorph and ProgressBarMorph > in addition to SystemProgressMorph > > and of course JobProgressMorph and JobProgressBarMorph > > to me it looks like this is ok to have > > - one with the forbidden flag = JobProgressMorph > - a default one = SystemProgressMorph > and the bar = ProgressBarMorph definitely the hierarchy is mess there. And there are indeed only 4 items needed - the Global displayed SystemProgressMorph which contains multiple progress indicators and the logics to force update the UI even when stuff runs in the UI thread - the item (title + progress bar) - the progress bar - the job item (title + progress bar + interrupt button) > and I saw that the size of the SystemProgressMorph is not passed to the its inner elements leading to this ugly bar getting out of the > size of the progress bar. the size should and has to be adapted automatically. Currently it's not properly updated since I removed a forced refresh, which makes it >factor 10 faster. Of course this should be rewritten once the previous points have been fixed.
