You're on Mac when you do that, right? OSProcess output redirection doesn't work in the latest Mac VM... my fault (introduced in the OSProcess plugin) :( but I have no idea why the fd dup / pipes work on Linux and not on Mac OS X.

And I remember also an issue with OSProcess in OSX in 5.0 and Spur...but cannot remember what exactly :( So it seems there is something going on there... -- Mariano http://marianopeck.wordpress.com

I do know that the Mac OSProcess plugin for Spur has an issue. Thierry

Re: [Pharo-dev] Status of GitFileTree in Pharo 5.0 and Spur

by Mariano Martinez Peck

mmmm ok, I am giving it a try but it seems it's not working or... mostly likely, I am doing something wrong. I just created a repo via github web interface, then I clone it to my machine, and then I tried to add the gitfiletree repo in MC Browser, but I get an error in: #currentBranch because #gitBranchs answered an empty array. But the `git branch` command was really executed as I can see the output of it in the stdout of the VM. So I guess OSProcess stdout setting may be what is not working?

Status of GitFileTree in Pharo 5.0 and Spur

by Mariano Martinez Peck

Hi Thierry, I had some problems with OSProcess in 5.0 with Spur so I wonder what's the status with GitFileTree. Is it working with latest 5.0? I tried to search some tests to confirm this but I found none. Thanks in advance, -- Mariano http://marianopeck.wordpress.com

I > think that's years away. Interesting. I have two questions: - what is the complexity you mentioned? To have an hierarchy of mirrors and calling the right now instead of a method? - for the speed cost: What was it exactly? Creating a mirror and sending a message that will then apply the primitive to the object? I imagine that they are some scenarios - like manipulating a remote object or a different space where the cost should be small compared to other operations At cadence what were the use of mirrors?

[Survey] Forking Operating System Proces in Pharo

by Mariano Martinez Peck

Dear all, As I mentioned in the thread "Pharo Consortium Sponsored Development Effort" [1] I built a survey about Forking Operating System Processes in Pharo. The idea of the survey is simple: I want to understand what people needs the most, which features would be useful, which ones would not, what is missing, what is wrong, etc etc etc. As always, since we have limited resources, we should optimize them as much as possible. I count with you so that we can make a roadmap together on this project. Please, feel free to forward this survey anywhere where there could be an interest. https://www.surveymonkey.com/r/DHR22TL Best regards, [1] http://forum.world.st/ANN-Pharo-Consortium-Sponsored-Development-Effort-td4… -- Mariano http://marianopeck.wordpress.com
