Greetings, if you are implementing this 64bit support in your VM, or
using it, you all should know that the test suite I posted back in
Dec does in fact NOT test for files > 2GB.
The eager folks out there should modify the test that checks for large files
testFileCreateAndSeekLargeFiles
and adjust the limits to some irrational whole numbers greater than
2GB bound by what your OS allows.
Note although my FreeBSD box claims to have a file 4,398,046,511,108
bytes in size, it lies (kinda), unlike the Mac OS which would
actually want real bytes around for that file and my wife refuses to
buy me a couple of terabytes of dasd right now.
Secondly I admit I did NOT cross check to confirm if you read/write
to files > 4GB that in fact what Squeak is doing is actually true or
if it is lying because of a coding error on my part. A bit of C code
might be needed or usage of dd using iseek might be need to confirm
things and it would be nice to get independent confirmation.
