Collections with more than a few thousand elements should use multiple blocks of memory (e.g. btree) to have acceptable insert performance. >Hmmm, opening a simple Array of 1.000.000 elements consumes 4 megabytes >in Pharo ... The point being? In a 64bit environment it will be 8MB. Only for bit/ byte sets or compressed collections it will be less. Cheap pc's currently have up to 16GB of memory, so the first 2.000.000.000 elements are no problem. Stephan

[Pharo-project] Iso-Collections ....
by stepken May 15, 2009

May 15, 2009

Hi! Frank sais: "Traditionally Smalltalk has one Object-Memory which is garbage-collected. This introduces overhead and complicates things in multihreading programs. LSWVST introduces multiple Object-Spaces, in which garbage collection can be controlled by the programmer. Every thread has its own Standard-Object-Memory avoiding synchronisation problems. Traditionally in Smalltalk every object is boxed. An object is a pointer which has a reference to the class. This is necessary to dynamically lookup the method during resolving a message-send. This makes programs which operate on huge data-collections of the same type rather inefficient. LSWVST introduces a new object-type - IsoCollections. Iso-Collections stores type information of its elements only once." Hmmm, opening a simple Array of 1.000.000 elements consumes 4 megabytes in Pharo ... regards, Guido Stepken

[Pharo-project] Underscores: clarifiation/thanks

Stef, I was thinking a little more about our correspondence earlier today and recalled something that appears to be correct. Stef wrote: "Sure. So far I do not know. I imagine that if you really want this to happen so you propose some code. As you see in the bugTracker we put _ in selector for 1.1" So that puts a partial solution plan in place for 1.1 instead of 2.0 as the original AST integrtion, which is real progress from my perspective. I see it!! There has been a long-standing patch that allows _ in selectors in any but the first position of a selector. Even that would be a help, it would be better still to allow them in all locations and of course in class names too. However, I will take what I can get, and am thrilled to see it on the agenda in any way prior to 2.0. I will help if I can, but doubt I am enough of a parser expert to be of real help, because it needs to be done solidly. It might also be that I can get the hack to work and start relying on it, knowing that I will stop being an rogue by 1.1. Thanks!!! Bill

[Pharo-project] accessors
by Steve Wirts May 14, 2009

May 14, 2009

Hi Folks, Would it be inappropriate to request that an effort be made at some point to try to provide accessors for all instance/class instance variables, and try to get rid of inappropriate direct variable accessing where possible? The "chasing variables" function is handy but seems more cumbersome than just putting a halt in a setter. I know this would be a lot of work but maybe it could be automated. Just tell me to shut up and go away if I'm being a nuisance. Steve :)
