Mac carbon VM 3.8.15b1 pending

I put a new macintosh carbon VM on my idisk and FTP site
http://www.smalltalkconsulting.com/squeak.html

Squeak 3.8.15beta1U.app.zip


This VM incorporates some changes to fix issues with sound recording/
playback crashes that the Scratch Support team found.
It fixes a problem with untrustedUserDirectory that Tetsuya HAYASHI  
found.
It fixes an issue with the alternate grow VM memory logic that the  
Sophie Team found.


VM changes are:

3.8.15b1 interp.c
                        Alter VMMaker logic to put in missing period in
                                biasToGrow
                                | growSize |
                                growSize :=  growHeadroom*3/2 - (self sizeOfFree: freeBlock).
                                self growObjectMemory: growSize

                        sqMacSecurity.c
                                untrustedUserDirectory  remove fixPath that Tetsuya HAYASHI  
reported stripping last directory
                                off of untrusted directory path that is in info.plis
               
                        sqUnixSoundMacOSXJMM.c
                                        dprintf, change to #define otherwise use of dummy method causes  
compiler to push parms,
                                        resulting in crash if buffer was not allocated on startPlay

3.8.14b8 Basis for MIT Scratch VM
                       
                        sqUnixSoundMacOSXJMM.c
                                        Changes to recording buffer logic to watch for buffer being  
freed by main thread, since
                                        recording buffer logic runs on separate os-x process. Issue was  
crash on stop recording
                                        Where we seem to stop the recording and dispose of the buffer,  
but then the buffer
                                        recording logic on the other thread (osx 10.3) wants to memcopy  
just one more buffer...

3.8.14b7 sqMacMain.c Add signal handler on SIGSEGV, dump all stacks.

Hi John,
    just a note, I try it and it is a lot more fast than the previous
one
Thank for the good work.

Raymond

How interesting...

Could people run a few tinybenchmarks for me

10 timesRepeat: [Transcript show: 1 tinyBenchmarks printString;cr]

with a 3.8.14 versus 3.8.15b1  VM

let me know if the machine is powerpc, versus macIntel.

Hi Brian,

what clock speed does your G4 have?

Best,

phew. I was wondering what I have been doing to my G4. ;-)
