errors while building a cog development image
by Sophie Kaleba 03 May '17

03 May '17

Hi, I have tried to build a cog dvlpt image using the following instructions : $ git clone http://www.github.com/OpenSmalltalk/opensmalltalk-vm $ cd opensmalltalk-vm/image $ ./buildspurtrunkvmmakerimage.sh while running the script, i get 2 errors (see attached file): - "Context cannot be changed" - and then "stackp store failure" which prevent me from actually building the image (the last error goes in an infinite loop) Has anyone ever experienced this problem? I am using Ubuntu 15.10, 64 bits. Thanks Sophie

Informing the VM that the display bits have changed via primitiveBeDisplay
by Eliot Miranda 02 May '17

02 May '17

Tim, John, Bert, et al, if you look at e.g. resizing code in the platforms/iOS code (in e.g. platforms/iOS//vm/OSX/sqSqueakOSXOpenGLView.m) the code accesses the display bits by looking up the display object installed via primitiveBeDisplay in the specialObjectsArray: - (void) performDraw: (CGRect)rect { sqInt form = interpreterProxy->displayObject(); // Form CGContextRef context = (CGContextRef)[[NSGraphicsContext currentContext] graphicsPort]; CGContextSaveGState(context); int width = interpreterProxy->positive32BitValueOf(interpreterProxy->fetchPointerofObject(1, form)); int height = interpreterProxy->positive32BitValueOf(interpreterProxy->fetchPointerofObject(2, form)); sqInt formBits = interpreterProxy->fetchPointerofObject(0, form); // bits void* bits = (void*)interpreterProxy->firstIndexableField(formBits); // bits int bitSize = interpreterProxy->byteSizeOf(formBits); int bytePerRow = 4*width; This is really unsafe. If it gets called while the VM is compacting, or doing a become, then potentially boom! Storing the display in the specialObjectsArray stops it form being GCed, but it doesn't stop it moving around, and it doesn't stop a become altering the location of the objects surrounding it, etc. Surely a better approach is to inform the VM of the location, depth and extent of the bits via some ioSetDisplayBits function and then cacheing those values somewhere in the VM. Thoughts? P.S. John McIntosh tells me that you, Tim R, may have written such code in the past. _,,,^..^,,,_ best, Eliot

Can someone LMK and/or fix it along these lines?
