Fwd: [Pharo-project] is it possible to know the memory occupation (bytes) of an object?
by Mariano Martinez Peck 29 Apr '10

29 Apr '10

Hi folks. Sorry for the cross post this time, but I guess it is worth. In Pharo we were trying to get a way to know the amount of memory (bytes) that an objects is occupying in RAM memory. For such purpose, Adrian posposed the following method: Object>>sizeInMemory "Returns the number of bytes used by this object in memory (including its header)" | headerSize instanceSize | headerSize := (self class indexIfCompact > 0 ifTrue: [ 4 ] ifFalse: [ 8 ]). instanceSize := (self class isVariable ifFalse: [ self class instSize * Smalltalk wordSize ] ifTrue: [ (self basicSize * (self class isBytes ifTrue: [ 1 ] ifFalse: [ Smalltalk wordSize ])) ]). ^ headerSize + instanceSize Do you think this is correct for all cases? Is there a way to know this but from the VM side also ? how ? I really need it from the VM side :( but I have no idea how to do it.

[Unix] spaces in realpath
by Bert Freudenberg 29 Apr '10

29 Apr '10

Hi Ian, the realpath() function in the "squeak" script does not like spaces in the path. Here is one that doesn't mind (only else-case differs): realpath () { path="$1" while test -L "${path}"; do dir=`dirname "${path}"` dir=`cd "${dir}" && pwd -P` path=`basename "${path}"` path=`ls -l "${dir}/${path}" | sed 's,.* -> ,,'` path="${dir}/${path}" done if test -d "${path}"; then (cd "${path}" && pwd -P) else dir=`dirname "${path}"` file=`basename "${path}"` (cd "${dir}" && echo "`pwd -P`/${file}") fi } - Bert -

Win32 woes: VM_VERSION undefined

Hello, i just updated to the latest VMMaker/svn and when trying to compile, it bugs me about the subject. I am missing something (as usual? ;) or it should be set manually before build? If yes, then how & where? -- Best regards, Igor Stasenko AKA sig.

And it is something I very much want to do soon as it will make the threaded FFI Cog VM I've done much more scalable. No, I've not even started on it yet. But it will be part of the new object representation (much simpler class access) GC I also want to do.

How to return an array in a primitive ?
by Mariano Martinez Peck 28 Apr '10

28 Apr '10

Hi folks. I am writing some primitives in Interpreter and now I need to return more than one value. Of course, in a OOP the ideal would be to return an object that represents the result. That object would also have all the instance variables I want. So..first question, is it possible to create and push on the stack an object of my own class ? If true, con can I do it ? now...suppose I cannot do that, the other option is to create an array with the values I want to return, and then return the array. For this particular case, I have 3 or 4 interegers I would like to put in the array, and push it in the stack. Is this possible ? If true, how ? Are there other options for what I need ? Thanks in advance for any help. Mariano

Linux VM built, but can't run
by Igor Stasenko 28 Apr '10

28 Apr '10

after building and installing squeak vm.. i tried to run it: sig@sig-desktop:~/squeak$ squeak Squeak4.1.image could not find display driver vm-display-X11; either: - check that /usr/local/lib/squeak/3.10-6/vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. Aborted i tried different things: - setting LD_LIBRARY_PATH=/usr/local/lib/squeak/3.10-6/ not helps. running with -plugins argument: sig@sig-desktop:~/squeak$ squeak -plugins /usr/local/lib/squeak/3.10-6 Squeak4.1.image don't helps either.. changing the /etc/ld.so.conf cat /etc/ld.so.conf include /etc/ld.so.conf.d/*.conf /usr/local/lib/squeak/3.10-6 don't helps too. symlinking /usr/local/lib/squeak/3.10-6/vm-display-X11 to /usr/local/lib/squeak/3.10-6/vm-display-X11.so still no success.. i'm out of variants.. WTF???? -- Best regards, Igor Stasenko AKA sig.

by Igor Stasenko 28 Apr '10

28 Apr '10

Hello CMake gurus. My plugin having a routine, written in assembly which i put into a file callgate.s it should be added to compilation (to produce a callgate.o) and linked into a final plugin's library together with object compiled from plugin sources generated by VMMaker. Any clues , what i should patch in order to achieve that? Some linux plugins having custom Makefile.inc config.cmake but i can't find a good example (yet), how i can make own, which fullfills my needs. -- Best regards, Igor Stasenko AKA sig.
