New subject: JUMP SHIP (Re: About 512 MB changes patch)

2 Oct 2006


      Hi
Ok, I had an 3.9 7051 image that was very close at 32 MB. I could
either rebuild a new image from scratch or use the patch from Klaus.
Now I knew about the risks (wich are why it's not in 3.9) and that it
has not seen enough testing. But if nobody tests it because it has not
seen enough testing then nobody will test it and it will never see
enogh testing. So it basically boiled down to 'Who if not me? When if
not now?'
So I did
- loaded LargeSourceFilePointers-kwl.0.cs (said Proceed)
- did the doit
- loaded LargeSourceFilePointers-kwl.1.cs
- did the doit
loaded RefactoringEngine
run Lint on a package, did some fixes, commited via Monticello
run Lint on an other package, did some fixes, oops trace below
As you can see a CompiledMethod is in the preamble.
