Re: [Pharo-project] How to subclass Process and have it used by spawned blocks?

by Eliot Miranda

Hi Stefan, this sounds a lot like an issue that bit someone in squeak 4.x recently and was due to a bytecode compiler bug that I fixed. I can't find or remember the email associated with this, so if anyone does remember please speak up. Stefan, you might try running this in an updated squeak 4.1 image and compare the bytecodes. If you get different bytecodes then we need to port the compiler fixes from 4.1 trunk to Pharo.

Re: [Pharo-project] How to subclass Process and have it used by spawned blocks?

by Stefan Marr

Further testing reveals a strange behavior in the debugger. So, I am not sure where the problem is actually caused. I added a new local variable block to the method. block gets assigned aBlock (the parameter). If I executed Erlang spawn: [Transcript show: 'foo'], the '1 halt.' is executed as I mentioned before. However, the debugger does not allow me to access aBlock, there is a subscript out of bound exception. Interestingly, 'block' is accessible without error. If I now actually use 'block' instead of 'aBlock' in the executed block, then phenomena is reversed. Thus, the variable which is actually referenced in the code is not accessible anymore but gets somehow lost. They also get lost if I use both. I would still like to understand what is going on here. So any remarks are welcome. Thanks Stefan spawn: aBlock "Answer an ErlProcess running the code given in the parameter. The process isscheduled." | proc block | <primitive: 19> "Simulation guard" block := aBlock. proc := Process forContext: [1 halt. aBlock value.

Re: [Pharo-project] Alien Plugin for Linux

by Henrik Johansen

Uhm, this method (and many others in the extensions-category) have been present in their expected-by-Alien form in Pharo since at least 1.0 Probably a better idea to separate the Alien-"Core" into two packages, one which is actually needed, and one which you only need to load in really old Squeak/Cuis images in order to have it work. In which case you probably won't have method trailers either, and generate: #(0 0 0 0) is the proper extension. Come to think of it, you probably have to go back to pre-closure enabled for that to be the case, with the amount of platform support for alien vms offered back then, it might not be a bad idea to just ditch it entirely.
