Fixed underscore assignments in VMMaker and plugins
by Matthew Fulmer 05 Nov '09

05 Nov '09

I removed all underscore assignments from VMMaker and all plugins I could find[1]. Now VMMaker will load into cobalt. Could someone copy the packages from my repository into where these packages belong? All the updated packages are at: http://croquet-src-01.oit.duke.edu:8886/RayTracing.html They should go in the listed repositories: http://www.squeaksource.com/VMMaker.html VMMaker-mtf.148 http://www.squeaksource.com/OSProcessPlugin.html VMConstruction-Plugins-OSProcessPlugin-mtf.21 http://www.squeaksource.com/Balloon3D.html Balloon3D-Plugins-mtf.6 Balloon3D-Plugins-mtf.5 http://www.squeaksource.com/KedamaPlugins.html Kedama-Plugins-mtf.2 [1] I got the list of plugin packages from: http://squeakvm.org/unix/platforms/unix/doc/RELEASE_NOTES_3.11.3.2135 -- Matthew Fulmer (a.k.a. Tapple)

Win32 VM Service facility broken?
by Torsten Bergmann 04 Nov '09

>is not compiled in by default anymore That would explain it, maybe I should have digged in the makefile ... > Editing the registry is apparently the way you have to do it. Why manipulate the Registry, there are API's to create and register a service. >please point me to the appropriate documentation. According to: http://msdn.microsoft.com/en-us/library/ms682450(VS.85).aspx you can just pass the args with lpBinaryPathName to the CreateService() API. If you have a recent Java installed you will find an example in the "Java Quick Starter" (jqs.exe) service. If you open it in the control panel you will see that arguments are passed.

>If someone could tell me how to run VM as service, i may check. see http://wiki.squeak.org/squeak/105 If correctly installed it should run and there should also be an entry in HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services BTW: if you installed it you can remove it using: sc.exe delete MyService where MyService is the name you've given. >you can run a VM as a standalone app, with seaside server. Yes, I can always run squeak headless together with an entry in Autostart or use other workarounds. But it is not the same. Any Windows admin will tell you. Especially since you can use scripting or the management console to start/stop service on remote machines and the like ... With the SCM (Service control manager) I can manage it like any other service (including Apache). I can define if and when it's started. The VM provides the "-service" option and if it's broken we should really fix it. This would also allow people to create Smalltalk based application server products for their Seaside apps (similar to Apache) and so on ... >i consider services as an unnecessary and complex solution >for resident applications We dont have to discuss how good the API or Windows in general is. Any other service based program integrates nicely ... and so should Squeak. I dont think we should yet again ignore the outside world here. Especially since we know that it worked before....

This would stop using the VM for seaside/web apps running as a service on a windows machines. I know most people use linux for server apps, but it was always nice to run a local squeaksource server as a service - which is now not possible with the latest Win32-VM's. Are you at least able to confirm that it is broken? Bye T. -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01

Integer overflow with BitBlt rule 20 and depth 32
by Henrik Johansen 04 Nov '09

04 Nov '09

Any combination of alpha values with a sum greater than 383 will cause an overflow, and return an alpha of sum - 255. Works correctly in BitBltSimulator, but the generated x86 C-code fails. Reproduced on latest versions of both Windows and MacOSX VMs. (I don't have a Linux install) Not quite sure of the best way to fix this (and possibly other similarily effected rules when depth is 32) Cheers, Henry Tests: sourceForm destForm blt| destForm := Form extent: 1@1 depth: 32. destForm bits at: 1 put: ((192 << 24) + (255 << 16) + (255 << 8) + 255). sourceForm := Form extent: 1@1 depth: 32. sourceForm bits at: 1 put: ((192 << 24) + (33 << 16) + (25 << 8) + 27). blt := BitBlt new. blt sourceForm: sourceForm. blt sourceOrigin: 0@0. blt setDestForm: destForm. blt destOrigin: 0@0. blt combinationRule: 20. blt copyBits. ((blt destForm bits at: 1) digitAt: 4) = 255 - Using Simulator: |word1 word2| word1 := (192 << 24) + (255 << 16) + (255 << 8) + 255. word2 := (192 << 24) + (33 << 16) + (25 << 8) + 27. ((BitBltSimulator new initBBOpTable partitionedAdd: word1 to: word2 nBits: 8 nPartitions: 4) digitAt: 4) = 255

see http://lists.squeakfoundation.org/pipermail/vm-dev/2009-October/003289.html Any answers on this? At least anyone able to test on Windows? Thanks Torsten -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01
