In reference to: Minifying Woes
by Tom Braun 28 Aug '23

28 Aug '23

Hi all, I am new to the list, so I couldn’t answer directly to Minifying Woes (or at least didn’t know how to). I identified 75 VM intern objects in Tom’s (tobe) image, by loading it in the simulator and setting a halt after loading the image. With the following code: | collection | collection := OrderedCollection new. self allOldSpaceEntitiesDo: [:obj | (((self classIndexOf: obj) < self lastClassIndexPun) and: (self isImmediate: obj) not) ifTrue: [ collection add: obj] ]. (collection sorted: [:a :b | (self bytesInBody: a) > (self bytesInBody: b)]) collect: [:ea | ea hex -> (self bytesInBody: ea)] I get the following 75 objects: 1. A free chunk after all other objects. Can be ignored for the sake of minimising image size 2. Remembered set -> 1048592 byte 3. hiddenRootsObj -> 32848 byte 4 - 61. Pages of the mark and weakling stack -> respectively 32752 byte 62 - 74. arrays of the class table -> respectively 8208 byte 75. specialObjectsOop -> 520 byte As far as I can judge the stack pages and remembered set could be removed from the image to minimize it further. If I understand correctly the StackPages could be removed by using the SpurImagePreener. The remembered set Could be removed in the SpurImagePreener too (when the VM initialises the memory it initialises a new remembered set too, if it is nil). After a quick read of the SpurImagePreener I didn’t see that the remembered set gets removed. When I tried using the preener it resulted in an unusable image (both simulator and compiled VM couldn’t load it). I tried both: SpurImagePreener new preenImage: '/Users/tombraun/Desktop/Squeak6.0-22104-64bit copy.image' SpurImagePreener new writeDefaultHeader: true; savedWindowSize: 1@1; preenImage: '/Users/tombraun/Desktop/Squeak6.0-22104-64bit copy.image' Could be a me problem, as I did some changes to the memory management in my VMMaker image, although this shouldn’t influence the preener…. On this note @Eliot: why the decision to make the object stacks and the remembered set VM managed objects instead of allocating them separately? 1. We don’t need to keep them in a snapshot. All object stacks are empty after GC and as we flushed the new space pre snapshot The remembered set shouldn't need to be persisted too. 2. During GC we simply mark all stack pages and keep them alive. When we at least freed empty pages (after a limit, to prevent the running VM from having to allocate too many pages every GC?) I would see the value. What did I overlook or does it simply have historical reasons? Best, Tom (WoC)

Mailing lists updated | Please reclaim your mail address
by Marcel Taeumel 29 May '23

29 May '23

Hi all -- We successfully migrated our mailing lists from mailman2 and pipermail to mailman3 and HyperKitty: - https://lists.squeakfoundation.org/mailman3/lists/ - https://lists.squeakfoundation.org/archives/ Your subscriptions were transferred to the new system so that mail delivery continued to function as expected. To manage mail delivery and other preferences, you can now create an actual account using your mail address. Please do so at your earliest convenience: - https://lists.squeakfoundation.org/accounts/signup/?next=/mailman3/lists/ You might want to use a different password as mailman2 stored those in plaintext, which enabled the system to remind you of your current password as a "feature" ... ;-) This is not possible anymore. Best, Marcel
