Mac carbon Hydra VM
by John M McIntosh 15 May '08

15 May '08

I've posted a basic Hydra VM to the usual place http://smalltalkconsulting.com/squeak.html via ftp or the idisk, look in the experimental/Hydra Someone will need to point out where to find a Hydra based image. It will not work on the PowerPC, maybe later this year? It does not contain any of the usual bundled plugins: CroquetPlugin.bundle FloatMathPlugin.bundle FT2Plugin.bundle LocalePlugin.bundle mpeg3Plugin.bundle PrintJobPlugin.bundle QuicktimePlugin.bundle ServicesPlugin.bundle SpellingPlugin.bundle SqueakFFIPrims.bundle TestOSAPlugin.bundle UnixOSProcessPlugin.bundle Since none of those have been cross checked for issues with a Hydra VM. However thoughts are that they should just work. -- = = = ======================================================================== John M.

different behaviour for Carbon VM depending on how it's started
by Michael Haupt 05 May '08

05 May '08

Dear all, today, I came across some interesting (and, so far, unsettling) behaviour of the Carbon VM (on Mac OS X, of course). The scenario is this: inside the image, OSProcess is used to start a Python script that goes to daemon state after some time. The command line passed to OSProcess>>#waitForCommand: is 'python /path/to/script.py -some -args'. Here's the interesting bit. The OSProcess has an exit value of 256 (and does not work) when I start the image the "normal" way, i.e., by double-clicking it, or by drag-and-dropping it to a VM, or by issuing "open -a /path/to/SqueakVM.app my.image". The VM process, as shown by "ps x", looks like this: "/path/to/Squeak VM Opt.app/Contents/MacOS/Squeak VM Opt -psn_0_4199425". Conversely, when I start the same image by first starting the VM, either by double-clicking it or by starting it directly from the terminal command line ("open /path/to/SqueakVM.app" or "/path/to/SqueakVM.app/Contents/MacOS/Squeak\ VM\ Opt"), and then selecting the image from the file selection dialogue, everything is fine. The VM process, then, looks like this: "/path/to/Squeak VM Opt.app/Contents/MacOS/Squeak VM Opt" (i.e., without the "-psn..."). What is the difference, and why? I'm puzzled. Someone, please enlighten me. :-) Best, Michael
