Changes since 13675: - Fix cloning MessageSet's. - Pointer-chaser, display the id-hash of Morph's in the path to chased object. - Sending basicNew to CompiledMethod may crash the VM, so don't do that. - Fix incorrect display of underscore and caret in case of WideString displayed in DejaVu sans Strike fonts. |
Bad news I'm afraid. Found a serious bug in the final release candidate.
To reproduce, start up Squeak4.5-13680.image, download the current version of Collections to the package-cache (Collections-ul.564.mcz), and load it from the package-cache. There's an infinite recursion apparently due to WriteStream>>nextPutAll: being not understood (!!). For some reason the load decides to remove nextPutAll:. Here's part of the stack:

I don't have much time to investigate over the weekend but someone else with more Monticello smarts may figure this out.. BTW, it may be related to hashing. When I try the same thing in a Spur-ised Squeak4.5-13680.image (where I'm loading a patched version of Collections-ul.564.mcz to restore source to the changed methods in Character that have no source after the bootstrap) it locks up at a similar point but die to a deadlock in preference access. So I suspect that there's some instability in Monticello loading that's affected by the different identityHashes obtained in Spur and SqueakV3. I had hoped to use the release candidate on Spur before using it on SqueakV3 but hit this bug. Hubris :-( ... ;-)

Could you clarify exactly what you mean by "download the current
version of Collections to the package-cache (Collections-ul.564.mcz)"? I already had (Collections-ul.564.mcz) in my package-cache so I simply loaded it (even though its already loaded into 4.5-13680, so why am I/you doing it in the 1st place?). Nothing happened. No lockup. Same package version. No difference. On Sat, Mar 1, 2014 at 10:55 AM, Eliot Miranda <[hidden email]> wrote: > Bad news I'm afraid.

Yes. The issue was that the package on squeak45 was empty. Chris uploaded a valid file as I didn't have one locally. So panic over :p

In 4.6 and beyond, I'm sure thoughtful discussions about Universes and more will happen that will result some things being excluded in future image versions, but still loadable as external packages. |

Yea, I anticipate Ken and I pushing it over the top this week. We need to play with nginx and tinydns and that's it. (Unless there's something Ken knows about that I don't).

No > one took it out during 4.5. Right. It may or may not be a good idea to have Universes in the image, but that is a discussion for the next release cycle. Squeak 4.5 is complete. Dave |
