[Pharo-project] Problem with fork
by Mariano Martinez Peck July 6, 2009

July 6, 2009

Hi folks! I am doing some benchmarks and I having problems with fork (I think). I have this method collect: collect |semaphores tr| semaphores := Array new: 10. tr := ThreadSafeTranscript new. tr open. 1 to: 10 do: [ :index | semaphores at: index put: Semaphore forMutualExclusion ]. 1 to: 10 do: [:i | [ tr show: 'one fork'; cr. (semaphores at: i) signal. ] fork ]. semaphores do: [:each | each wait ]. tr show: 'all forks proccesed'; cr. What I want is that the method collect returns when ALL of the forks created inside, are finished. Obviously in my real code, I don't do a transcript show: but another thing. I would expect something like this: one fork one fork one fork one fork one fork one fork one fork one fork one fork one fork all forks proccesed But the output is: all forks proccesed one fork one fork one fork one forkone fork one fork one fork one forkone fork one fork one fork one forkone fork So, I guess it isn't working :( I don't know too much about forks so any help is welcome! can be a problem with ThreadSafeTranscript ? If so, how could I test if my code is working as expected ? Thanks, Mariano

[Pharo-project] Alternative Linux VM link is not closure support
by Mariano Martinez Peck July 6, 2009

July 6, 2009

If you follow the link of "alternative" for Linux, you will get the link http://squeakvm.org/unix/ squeak-vm_3.10-5_i386.deb seems not to have the closure enables and you get the error: This interpreter (vers. 6502) cannot read image file (vers. 6504). This is confusing for new people. We should remove that link or put the same as the first one (exupery). cheers, Mariano

[Pharo-project] Why does Pharo have both a System Browser and a Class Browser?
by Oscar Nierstrasz July 6, 2009

July 6, 2009

Hi folks, In the Tools ... menu there are entries for both a System Browser and a Class Browser. Both give you an OmniBrowser Package Browser. Is there a reason for this? Also, all the tools available from the World menu are available as well from the Tools menu. This just adds to confusion. Finally, there seems to be no way to push-pin submenus. Is that a conscious design decision, or just a random act of GUI violence? - on [migrating Squeak by Example to Pharo by Example]

[Pharo-project] What will be the standard browser in Pharo?
by Oscar Nierstrasz July 5, 2009

July 5, 2009

Hi Folks, I am trying to port Squeak by Example to Pharo by Example. I am a bit confused about what is suppose dto be the standard browser now. I thought it was the OB Package Browser, but Damien Cassou just gave me a new image where the browser is an OB System Browser (Categories, not packages). I cannot even see any more how to switch between the two. Can someone enlighten me? (Then I can explain it in the book.) - on
