==================== Summary ====================

Name: Collections.spur-ul.586
Author: eem
Time: 28 October 2014, 10:22:44.764 am
UUID: 2412b3e4-6494-45ce-b462-0a783482d92b
Ancestors: Collections-ul.586, Collections.spur-cmm.585

Collections-ul.586 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.212

Symbol table changes:
- ensure that enumerations stay consistent
- avoid read-write and write-write race conditions
- added a safe #condenseNewSymbols method, which is a replacement for former unsafe methods (#shutDown: and #compactSymbolTable). It's also automatically triggered whenever there are more than 1000 NewSymbols.
- deprecated #compactSymbolTable
- updated some comments

Note that interning many symbols is a bit slower, but thread safety is more important.

Well, this is gonna be interesting in the future.
Are SPUR MCZs now completely incompatible to non-spur MCZs?

This would be terrible…

No, but Spur has new class formats which are not recognized by
SqueakSource. I shouldn't be hard to fix it for someone who knows how
SqueakSource works, and what the new formats are.

SqueakSource uses the available Monticello.
This obviously means that the “old” monticello is incompatible to
the Class formats of SPUR, right?

Should be possible. But I have no access to it.

While we are at it; can we make provisions for
GemStone class formats? They differ ever so slightly
and it is really hard to keep all in sync.

We now have:
        Squeak/Pharo Class formats (ca Squeak 3.8 - Squeak 4.6/Pharo3.0)
        Squeak/Pharo SPUR Class Formats (current and possibly onward)
        GemStone class formats (somewhat mapped from the squeak ones)

I did a bit of coding for the gemstone monticello version about one or
two years back and the mapping between the known monticello class formats
and gemstone class formats is a little fragile, I think.

Good question. We should try it and find out. The source.squeak.org
and squeaksource.com servers are now running on pretty much the same
image, so if we can fix it for one we will fix it for both.

I'll try to look into this soon if noone else gets to it first.

Tobias,

If you do anything with this, please let me know if I can help. Your
own work on SqueakSource is more advanced than whatever we are currently
running on squeak.org and squeaksource.com, but if you want or need access
to those images I'll make sure you can get a copy. I don't think that we
should make them publicly downloadable because they may contain passwords
and personal information.

Note that I am not really a squeaksource expert, I'm just trying to keep
squeaksource.com running reliably. I'll try to update Monticello in a
copy of the existing squeaksource.com image, but if you have something
better that includes Gemstone support I would be happy to follow your lead
if possible.
