CogVM/StackVM fail to read in image, fine on Squeak 4.2.1 MacVM
by Stefan Marr 21 Jul '11

21 Jul '11

Hi: I recently added support to load images that have been saved with the CogVM in image format 6505 to the RoarVM. However, now I noticed that the CogVM/StackVM crash when they are asked to load an image which is saved by our RoarVM. Interestingly, the Squeak 4.2.1 and earlier are able to load this image. To reproduce the problem, I put online an image [1] which is a stock Squeak4.2-10966, just downloaded, opened and saved with the RoarVM. The Cog/StackVM fail to open it with an error in "0 org.squeakfoundation.Squeak 0x00033462 readImageFromFileHeapSizeStartingAt + 3058" Interestingly, if I open the image with Squeak 4.2.1, and save it and then open it in Cog, Cog does not crash. So, there might be some inconsistencies in our image loading/saving routines. Could someone give it a try on a VM instrumented for debugging and explain me what the problem is? There could be a bug in the RoarVM with filing out the image, but it is strange that Squeak 4.2.1 handles it just fine. Thanks Stefan [1] http://soft.vub.ac.be/~smarr/roarvm/squeak-saved-with-rvm.zip

request for two more entry points in the interpreter proxy
by Craig Latta 21 Jul '11

21 Jul '11

Hi-- Aha, in my own Spoon VMs I'd been using a couple of entry points I added to the interpreter proxy (sqVirtualMachine.h) that aren't in the official version. They are getNextWakeupTick() and setInterruptCheckCounter(), I use them in my pluggable relinquish-processor primitive. Would whoever owns the interpreter proxy definition add these, please? (Eliot or Dave, I assume.) thanks! -C -- Craig Latta www.netjam.org/resume +31 6 2757 7177 + 1 415 287 3547
