Re: [Pharo-project] Alien Plugin for Linux

by Fernando olivero

This Error prevents from using Alien in the lastest Pharo image. I will try to fix this today. Also i will remove the ConfigurationOfAlien from the Alien repository, because the version in MetacelloRepository should be used instead. So there are no future misunderstandings Thanks to Eliot, and using his precompiled Vms for all platforms Alien would be available now! (if the mentioned bug were fixed).

Re: [Pharo-project] Problem with Proxies, objects and MethoDict

by StÃ©phane Ducasse

Mariano why your proxy class does not have at least a format, methodDict and superclass? In the past Behavior new something was carashing the vm because methodDict was nil and boum it crashed. I fixed that long time ago. Now I think that a class proxy cannot be just the same as an object proxy from the vm look at structure.

Could you elaborate on that? No other process can be accepted for what? Being scheduled, or being executed? There is also a comment in the comment of Process which suggests that it should be possible: "(If anyone ever makes a subclass of Process, be sure to use allSubInstances in anyProcessesAbove:.)" But even after making the change, that does not seem to be the actual problem. The process gets execute fine. With a '1 halt.' as the first statement of the aBlock block I even get a debugger. It only fails on accessing variables referenced by the closure with an index out of bound error or something similar. >> Erlang>>spawn: aBlock >> "Answer an ErlProcess running the code given in the parameter. >> The process is scheduled." >> | proc | >> proc := ErlProcess >> forContext: >> [1 halt. aBlock value. >> Processor terminateActive] asContext >> priority: Processor activePriority. >> proc resume. >> ^ proc Thanks and best regards Stefan -- Stefan Marr Software Languages Lab Vrije Universiteit Brussel Pleinlaan 2 / B-1050 Brussels / Belgium http://soft.vub.ac.be/~smarr Phone: +32 2 629 2974 Fax: +32 2 629 3525

On > 30k was a bit optimistic assumption. For example the Pharo 1.1 OneClick image has 3220 globals. The sortBlock asks for the preference twice per evaluation. SortedCollection uses a binary search during #add:. If we are optimistic, then the preference is asked 3220 * (3220 ln / 2 ln) * 2 times which is ~75k. > > In the same image the "old" code asked for the preference 2282899 times during the tests, while the new code did it only 398 times. If the preference is changed to return the value of a variable, then the difference is only 80 ms, otherwise it's 36.6 seconds.
