One bytecode missing in initializePushConstantBytecodeTable
by André Wendt 09 Apr '08

09 Apr '08

Hello everybody, is there any reason for pushConstantTrueBytecode to be missing from Interpreter class>>#initializePushConstantBytecodeTable ? There's only seven instead of eight values in the table. BTW, this is on 3.9, I didn't check 3.10. Regards, André

SecureDirectory and UserDirectory handling in Windows VM
by Yoshiki Ohshima 08 Apr '08

08 Apr '08

Hello, In Squeak.ini, you can specify SecureDirectory and UserDirectory to specify the values used by: SecurityManager default untrustedUserDirectory. SecurityManager default secureUserDirectory. About a year ago, there was a discussion initiated by korakurider about expanding the environment variable in SecureDirectory: http://squeakland.org/pipermail/squeakland/2007-February/003438.html but the issue seems to be still there. Is there any plan to update the VM for it? That would be very helpful to package the new Squeakland release (based on the OLPC Etoys image). Thank you! -- Yoshiki

Object>>#at:put: reports improper store when everything seems fine
by André Wendt 05 Apr '08

05 Apr '08

Hi, I just stumble upon this: Object>>#at:put: calls <primitive:61>. If that fails, the following lines read index isInteger ifTrue: [self class isVariable ifTrue: [(index >= 1 and: [index <= self size]) ifTrue: [self errorImproperStore] Why is it an improper store if the index is an integer, the receiver class is variable, and the index is within bounds? Someone please enlighten me... (If this is merely reporting "there was an error in the primitive although everything's alright", then I feel the message should be something other than "Improper store into indexable object".) Thanks, André

He Kelly, (CC to the vm-dev list) I don't know the answer to your question, but there is a separate mailing list devoted to Squeak VM development that may be of some help. http://lists.squeakfoundation.org/mailman/listinfo/vm-dev - Dave On Sun, Mar 23, 2008 at 10:13:12AM -0600, Kelly Wilson wrote: > Hello everyone, > > > > I recently ported squeak to Syllable OS and it runs with vm-display-null and > vm-sound-null just fine.
