It seems my mail was not clear at all. I know that with #cleanUpForRelease it will reduce, but my question is....if I understand correlty what a Bitmap is, why they are nstantiated when I am running headless? shouldn't the amount of instances be 0? I think I don't understand what really the -headless does. I thought the world was not display, not Bitmap was instanciated, etc... cheers Mariano > HTH, > > Sven > > On 24 Aug 2010, at 14:18, Mariano Martinez Peck wrote: > > I took a dev image, and run them in two ways: the normal and headless.

Thanks Stef! It loads ok on the latest PharoCore 1.2. A quick try show me that the tests don't work mainly because the changes on UI. I can add this to my infinite to-do list and take a look if is worth to the community. Also we should add a repo on SqueakSource?

[Pharo-project] why are Bitmaps instanciated even in headless mode?

by Mariano Martinez Peck

I took a dev image, and run them in two ways: the normal and headless. For each I did a: "Smalltalk garbageCollect. SpaceTally new printSpaceAnalysis" Normal one: Class code space # instances inst space percent Bitmap 3753 133 11099904 37.4 ByteString 2515 85110 6106378 20.6 CompiledMethod 19130 59452 3703463 12.5 Array 2176 77579 2561928 8.6 ...... Headless: Class code space # instances inst space percent ByteString 2515 85110 6106378 24.7 Bitmap 3753 126 6049208 24.5 CompiledMethod 19130 59452 3703463 15.0 Array 2176 77577 2561844 10.4 ...... So....even in headless mode, I have 133 instances of Bitmap, representing 24.5% of the memory.... Ok, 24.5 is better than 37.5, but I don't understand why Bitmap instances are created. Why they are needed ? is there a way to garbageCollect them? thanks Mariano

Re: [Pharo-project] 'foo' asTime

Thinking aloud. I usually don't have to write dates in my code, because they are picked by the user. I think that a well built kernel and nice well integrated UI widgets (maybe I'm going out of the scope :P ) are enough in most of the cases.
